Embodiments for Carrying Out the Invention

[0009] Hereinafter, the present invention will be specifically described based on the drawings showing its embodiments. (Embodiment 1) FIG. 1 is an explanatory diagram for explaining the process of transporting construction-generated soil. The construction-generated soil generated at a construction site is a useful renewable resource that can be used for land reclamation and the like as landfill or embankment materials. The construction-generated soil generated at the construction site is loaded onto a transport vehicle such as a dump truck and transported to a stockyard or the like.

[0010] A stockyard is a place where the construction-generated soil carried in by transport vehicles is temporarily deposited. The stockyard is operated by a for-profit or non-profit operator. The construction-generated soil deposited in the stockyard is further transported to another stockyard or a final disposal site. The final disposal site is a landfill or an embankment construction site, etc. The construction-generated soil generated at the construction site may be transported to the final disposal site via one or more stockyards from the construction site, or may be directly transported to the final disposal site. Also, the construction-generated soil may be transported to other construction sites.

[0011] On the other hand, when the demand for construction-generated soil decreases, it is also assumed that the surplus soil removed at the construction site has no destination and accumulates, and is left as an embankment. Even if the embankment that has been dug up and moved is leveled and solidified, it is fragile compared to when it was in its original ground. When heavy rain occurs, the risk of the boundary between the ground and the embankment collapsing and crumbling increases. In order to reduce such risks, the Land Reclamation and Specific Embankment, etc. Regulation Law (Embankment Regulation Law), which has as its basic policy ensuring the safety of embankments, etc., clarifying the location of responsibility, and effective penalty measures, has been implemented.

[0012] In addition, in accordance with the implementation of the earthwork regulation law, a stockyard registration system has been established. The stockyard registration system is a system established for the purpose of cultivating excellent stockyards and promoting the proper treatment and recycling of construction-generated soil. Prime contractors who undertake construction work involving the removal of construction-generated soil are obliged to confirm the location of the construction-generated soil until the final destination of removal to ensure that the removed construction-generated soil is not used for illegal or dangerous embankments. Therefore, prime contractors are required to request the delivery of a receipt from the destination and keep a copy of the receipt for a specified period. Also, when the soil is further removed from the above-mentioned destination to another destination, unless the destination is a place managed by the state or a local public body or a stockyard registered with the state (hereinafter referred to as a registered stockyard), a written confirmation of the location until the final destination of removal must be created and kept for a specified period. On the other hand, when construction-generated soil is removed to a registered stockyard, the operator of that stockyard takes over the subsequent proper removal, so the prime contractor does not need to confirm the location of the construction-generated soil until the final destination of removal, reducing the burden on the prime contractor. Since registered stockyards are more likely to be selected by prime contractors as destinations for removing construction-generated soil, this is beneficial for operators.

[0013] Hereinafter, an information providing system that centrally manages information on destinations including stockyards and final disposal sites and provides information on candidate destinations in response to requests from prime contractors will be described.

[0014] FIG. 2 is a schematic diagram showing a configuration example of the information providing system according to Embodiment 1. The information providing system according to Embodiment 1 includes a prime contractor terminal 100, a worker terminal 120, operator terminals 140 and 160, and a management server 200. These terminals 100 to 160 and the management server 200 are communicably connected via a communication network NW1.

[0015] The prime contractor terminal 100 is a terminal used by the prime contractor who undertakes the work of transporting construction-generated soil. The worker terminal 120 is a terminal used by the worker who performs the loading and unloading operations of construction-generated soil. The worker terminal 120 may be a terminal owned by the worker himself / herself or a terminal mounted on a transport vehicle. The operator terminals 140 and 160 are terminals used by the operators of the stockyard and the final disposal site, respectively. These terminals 100 to 160 are existing terminals such as personal computers, smartphones, and tablet terminals, and are equipped with an operation unit (input interface) that accepts the user's operation, a communication unit (communication interface) that transmits and receives various information via the communication network NW1, a display unit (display) that presents necessary information to the user, and the like.

[0016] The management server 200 is an information processing device that centrally manages the information of the unloading destinations including the stockyard and the final disposal site and provides information in response to requests from the prime contractor. Hereinafter, the configuration of the management server 200 will be described.

[0017] FIG. 3 is a block diagram for explaining the internal configuration of the management server 200. The management server 200 is a dedicated or general-purpose computer and includes a control unit 201, a storage unit 202, a communication unit 203, an operation unit 204, and a display unit 205.

[0018] The control unit 201 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. In the ROM included in the control unit 201, a control program for controlling the operations of each part of the hardware included in the management server 200 and the like are stored. The CPU in the control unit 201 executes the control program stored in the ROM and the information providing program PG described later stored in the storage unit 202, and controls the operations of each part of the hardware, thereby causing the entire device to function as the management server 200 (information processing device) of the present disclosure. In the RAM included in the control unit 201, data and the like used during the execution of calculations are temporarily stored.

[0019] The control unit 201 may be one or more control circuits or arithmetic circuits including a GPU (Graphics Processing Unit), an FPGA (Field Programmable Gate Array), a volatile or non-volatile memory, etc., not limited to the above configuration. Further, the control unit 201 may have functions such as a clock that outputs date and time information, a timer that measures the elapsed time from when a measurement start instruction is given until a measurement end instruction is given, and a counter that counts numbers.

[0020] The storage unit 202 includes a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). Various computer programs executed by the control unit 201 and data necessary for various processes are stored in the storage unit 202.

[0021] The computer programs stored in the storage unit 202 include an information providing program PG that manages information on delivery destinations including the stockyard and the final disposal site and provides it to the prime contractor terminal 100 and the worker terminal 120 as necessary. The information providing program PG may be a single computer program or a program group composed of a plurality of computer programs. Further, the information providing program PG may partially use an existing library. The information providing program PG may be executed by a single computer or may be executed in cooperation by a plurality of computers.

[0022] A computer program including an information providing program PG is provided by a non-transitory recording medium RM (program product) in which the computer program is recordable. The recording medium RM is, for example, a portable memory such as a CD-ROM, a USB memory, an SD (Secure Digital) card, or the like. The control unit 201 reads a necessary computer program from the recording medium RM using a reading device (not shown in the figure) and stores the read computer program in the storage unit 202. Alternatively, a computer program including the information providing program PG may be provided by communication. In this case, the control unit 201 acquires a computer program including the information providing program PG by communication via the communication unit 203 and stores the acquired computer program in the storage unit 202.

[0023] In addition, the storage unit 202 includes a registration information management database DB that stores registration information regarding the disposal destinations of construction-generated soil including the stockyard and the final disposal site. The information registered in the registration information management database DB will be described in detail with reference to FIG. 4.

[0024] The communication unit 203 includes a communication interface for transmitting and receiving various data to and from an external device. As the communication interface of the communication unit 203, a communication interface compliant with existing communication standards such as WiFi (registered trademark), LAN (Local Area Network), Bluetooth (registered trademark), ZigBee (registered trademark), 3G, 4G, 5G, LTE (Long Term Evolution), etc. can be used. When data to be transmitted is input from the control unit 201, the communication unit 203 transmits the data to the destination external device, and when receiving data transmitted from the external device, the communication unit 203 outputs the received data to the control unit 201. In the present embodiment, the external devices are the prime contractor terminal 100, the worker terminal 120, and the operator terminals 140 and 160.

[0025] The operation unit 204 is provided with operation devices such as a touch panel, a keyboard, and switches, and accepts various operations and settings by an administrator or the like. The control unit 201 performs appropriate control based on various operation information given from the operation unit 204, and stores setting information in the storage unit 202 as necessary.

[0026] The display unit 205 is provided with a display device such as a liquid crystal display or an organic EL (Electro-Luminescence) display, and displays information to be presented according to an instruction from the control unit 201.

[0027] In the present embodiment, the management server 200 may be a single computer, or may be a computer system configured by a plurality of computers, peripheral devices, or the like. Further, the management server 200 may be a virtual machine in which the entity is virtualized, or may be a cloud.

[0028] FIG. 4 is a conceptual diagram showing a configuration example of the registration information management database DB. The registration information management database DB stores information such as an operator, a recipient name, a registration number, a location, a depositable amount, acceptance availability, usage time, a fee, a soil quality classification, and acceptance conditions in association with each recipient of construction-generated soil. Recipients of construction-generated soil include registered stockyards (stockyards registered in the country), unregistered stockyards (stockyards not registered in the country), final disposal sites, construction sites, and the like. In the following, when there is no need to distinguish between recipients, these are collectively referred to as stockyards or the like. The management server 200 communicates with the operator terminals 140 and 160 of stockyards or the like through the communication unit 203 to acquire necessary registration information, and stores the acquired registration information in the registration information management database DB.

[0029] In this embodiment, the stockyard is classified into a registered stockyard and a non-registered stockyard, but these classifications are merely for convenience. For example, the stockyard may be classified into a first stockyard that has received approval (such as authorization, certification, permission, or consent) from a predetermined institution or organization such as a country, and a second stockyard that has not received approval (such as authorization, certification, permission, or consent). In the present disclosure, a stockyard that has been registered, approved, certified, permitted, consented, etc. by a predetermined institution or organization is described as a registered stockyard, and a stockyard that has not been registered, approved, certified, permitted, consented, etc. by a predetermined institution or organization is described as a non-stockyard.

[0030] In the item of the operating operator, the name of the operator who operates the stockyard etc. is stored. In the item of the recipient name, the name of the stockyard etc. is stored. In the item of the registration number, in the case of a registered stockyard, the registration number registered in the country is stored. In the case of a non-registered stockyard (a stockyard not registered in the country), the item of the registration number is blank. In the item of the location, the address (location information) of the stockyard etc. is stored.

[0031] In the item of the depositable amount, the maximum amount of construction-generated soil that can be received in the stockyard etc. is stored. In the item of the acceptance possibility, information on whether construction-generated soil can be accepted is stored. Whether construction-generated soil can be accepted is determined by the operating operator who operates the stockyard etc. The acceptance possibility can be appropriately changed from "yes" to "no" or from "no" to "yes" according to the usage status of the stockyard etc. The management server 200 communicates with the operator terminals 140, 160, etc. to obtain the determination result of the acceptance possibility by the operating operator, and updates the item of the acceptance possibility according to the obtained determination result. Also, in addition to the acceptance possibility, the amount (volume) of construction-generated soil that can be accepted at that time may be registered.

[0032] Furthermore, the acceptance status item may be updated according to the reservation for removal from the prime contractor or the transport vehicle. For example, when the prime contractor or the worker makes a reservation for removal to the operator and notifies the estimated amount of construction waste to be removed, the acceptance status item in the registration information management database DB may be updated accordingly. In this case, at the time of making the removal reservation, the prime contractor terminal 100 or the worker terminal 120 notifies the operator terminals 140, 160 of the information on the estimated amount of removal. The operator terminals 140, 160 transmit the notified information on the estimated amount of removal to the management server 200. The management server 200 updates the amount of construction waste that can be accepted in its stockyard or the like based on the information received from the operator terminals 140, 160. Also, when the updated amount of construction waste that can be accepted becomes less than the set value, the management server 200 updates the acceptance status item from "acceptable" to "not acceptable". By adopting such a configuration, it is possible to avoid a situation where the carrier that made the removal reservation cannot perform the removal due to another carrier having performed the removal work between the reservation and the arrival at the stockyard or the like.

[0033] The item of usage time stores information on the usage time of the stockyard or the like. The item of fee stores information on the fee of the stockyard or the like. The fees may be registered separately for the fee collected by the operator when the construction waste is brought into the stockyard or the like and the fee collected by the operator when the construction waste is removed from the stockyard or the like. In addition to the item of usage time, an acceptable date item indicating acceptable days of the week, holidays, Golden Week, Obon, New Year's holidays, etc. may be included.

[0034] The soil classification represents the type of construction-generated soil. The construction-generated soil is classified, for example, into the first type to the fourth type of generated soil or muddy soil. The first type of generated soil includes sand, gravel, and those similar thereto. The second type of generated soil includes sandy soil, gravelly soil, and those similar thereto. The third type of generated soil includes cohesive soil with ensured normal workability and those similar thereto. The fourth type of generated soil includes cohesive soil and those similar thereto. In each item of the soil classification, information on the acceptability for each type is stored. In the example of FIG. 4, "○" indicates that acceptance is possible, and "×" indicates that acceptance is not possible. The soil classification is not limited to the above and can be set as appropriate.

[0035] In the item of acceptance conditions, acceptance conditions such as those of the stockyard are stored. In the example of FIG. 4, as acceptance conditions, public works only, own company works only, and no restriction on the source of delivery are set. When the stockyard etc. accepts construction-generated soil limited to public works, "○" is stored in the item of public works only. When the stockyard etc. accepts construction-generated soil limited to own company works, "○" is stored in the item of own company works only. Also, when there is no restriction on the source of delivery of the construction-generated soil, "○" is stored in the item of no restriction on the source of delivery.

[0036] Note that in this embodiment, the registration information management database DB is provided in the storage unit 202 of the management server 200, but the registration information management database DB may be outside the management server 200. In this case, the management server 200 may access the registration information management database DB via the communication unit 203.

[0037] Hereinafter, the operation of the information providing system will be described. FIG. 5 is a flowchart for explaining the operation of the information providing system. When the prime contractor receives information on candidates for the unloading destination from the management server 200, as preparatory work, the prime contractor checks the working status of the transport vehicles it manages. Specifically, the prime contractor terminal 100 acquires information on the current position of the transport vehicle that is about to unload the construction-generated soil to a stockyard or the like from the worker terminal 120, and information on the loading amount of the construction-generated soil loaded on the transport vehicle (step S101). The current position of the transport vehicle is measured by a GPS (Global Positioning System) system mounted on the transport vehicle or the worker terminal 120. Also, when a weighing scale is mounted on the transport vehicle, the loading amount of the construction-generated soil is measured using the weight of the construction-generated soil measured by the weighing scale and the density of the construction-generated soil. The density of the construction-generated soil may be assumed to be known. For example, regarding the weighing of the construction-generated soil, by using the configuration disclosed in Patent No. 7208888 or the like, it is possible to output with high accuracy even under various conditions. Regarding the density, it may be calculated in a form using a virtual volume based on the captured image with a camera or the like and the weight, or in a form of obtaining information from construction vehicles and their workers at the construction site, or in a form of excluding the information of the measurement target.

[0038] Next, the prime contractor terminal 100 causes the reception screen provided by the management server 200 to be displayed on the display unit of the prime contractor terminal 100 (step S102). FIG. 6 is a schematic diagram showing an example of the reception screen. The reception screen 10 shown in FIG. 6 is a screen for receiving information on the transport vehicle that is about to unload the construction-generated soil to a stockyard or the like. The prime contractor terminal 100 can access the management server 200 and cause the reception screen 10 as shown in FIG. 6 to be displayed on its own display unit, for example, by performing login authentication.

[0039] The reception screen 10 includes a current location input field 11, a loading capacity input field 12, a soil type selection field 13, and a transmission button 14. Information on the current location of the transport vehicle is input into the current location input field 11. Information on the loading capacity of the construction-generated soil loaded on the transport vehicle is input into the loading capacity input field 12. The information on the current location and loading capacity of the transport vehicle may be automatically input with the information obtained in step S101, or may be manually input by the prime contractor. The soil type selection field 13 is a selection field in the form of a pull-down menu, and accepts a selection of which soil type category the construction-generated soil loaded on the transport vehicle belongs to. The transmission button 14 is a button for transmitting the input or selected information to the management server 200.

[0040] On the reception screen 10, when various information is input or selected and the transmission button 14 is pressed, the prime contractor terminal 100 transmits a search request for unloading destination candidates to the management server 200 (step S103). Note that it is preferable that the search request at least includes information on the current location of the transport vehicle, and may further include information on the loading capacity or soil type.

[0041] The management server 200 receives the search request transmitted from the prime contractor terminal 100 via the communication unit 203 (step S104). The control unit 201 of the management server 200 searches for unloading destination candidates from the registration information management database DB based on the received search request (step S105). When the search request includes information on the current location of the transport vehicle, the control unit 201 searches the registration information management database DB for stockyards, etc. that are within the set distance range (for example, within 30 kilometers) from the current location of the transport vehicle among those for which acceptance is "OK" at that time. When the search request includes information on the loading capacity, the control unit 201 may search the registration information management database DB for stockyards, etc. that can accept that amount. Further, when the search request includes information on the soil type, the control unit 201 may search the registration information management database DB for stockyards, etc. that can accept the construction-generated soil of that soil type.

[0042] In addition, among the stockyards and the like registered in the registration information management database DB, the registered stockyards may be preferentially searched. For example, a registered stockyard that is a candidate for the destination of conveyance is searched from the registration information management database DB. If there is no corresponding registered stockyard, an unregistered stockyard, another construction site, a final disposal site, or the like may be searched.

[0043] The management server 200 transmits the search result of the candidates for the unloading destination to the prime contractor terminal 100 (step S106). The search result may include various information registered in the registration information management database DB. Further, the detection result may indicate the candidates for the unloading destination by distinguishing between the registered stockyards and the unregistered stockyards.

[0044] The prime contractor terminal 100 receives the search result of the candidates for the unloading destination transmitted from the management server 200 (step S107), and causes the display unit to display the information of the candidates for the unloading destination (step S108). FIG. 7 is a schematic diagram showing an example of the display of the candidates for the unloading destination. In the display example of FIG. 7, the candidates for the unloading destination are shown in a list format by distinguishing between the registered stockyards and the unregistered stockyards. In the display example of FIG. 7, information such as the operator, the name of the receiving party, the registration number, the location, the usage time, and the fee is shown, but information such as the soil classification, the available receiving date, and the receiving conditions may be further included.

[0045] As described above, in the first embodiment, the management server 200 can refer to the registration information management database DB in response to a request from the prime contractor and output information on candidates for the conveyance destination where the construction-generated soil can be received.

[0046] In the first embodiment, the management server 200 searches the registration information management database DB in response to a search request from the prime contractor terminal 100 and returns the search result. However, the management server 200 may be configured to search the registration information management database DB in response to a search request from the worker terminal 120 used by the worker himself / herself and return the search result.

[0047] In addition, the information providing system may include the prime contractor's server (hereinafter referred to as the prime contractor server). The prime contractor server is a server that constitutes a construction management system in the prime contractor and manages the details of the construction. The prime contractor server is communicably connected to the communication network NW1. Information on construction-generated soil measured in a vehicle or at a construction site and the position information of the transport vehicle are uploaded to the prime contractor server. The prime contractor server may send a search request including the information on construction-generated soil and the position information of the transport vehicle to the management server 200, and as a response thereto, receive information on a stockyard or the like searched by the management server 200 via the communication network NW1.

[0048] In addition, since the search request includes information on the current position of the transport vehicle and the position information of a stockyard or the like is included in the registration information management database DB in the management server 200, the fuel consumption of the transport vehicle can be calculated based on these pieces of information. Further, the management server 200 multiplies the calculated fuel consumption by the calorific value per unit usage, the carbon emission per unit calorific value, and a predetermined coefficient to calculate the CO 2 emission amount. Further, the management server 200 may consider the vehicle weight of the transport vehicle when calculating the CO 2 emission amount. Since the vehicle weight varies depending on the loading amount in the transport vehicle, the management server 200 may directly or indirectly acquire the information on the loading amount measured in the transport vehicle from the transport vehicle. The management server 200 may include the calculated CO 2 emission amount in the search result and present it to the prime contractor.

[0049] In addition, when sending the search result of the unloading destination candidates in response to a request from the prime contractor, the management server 200 may generate a map in which information such as the current position of the transport vehicle, the position of the unloading destination candidates, the fee, and the CO 2 emission amount is superimposed, and send the generated map as the search result to the prime contractor terminal 100. When the prime contractor terminal 100 receives the map (search result) sent from the management server 200, it is displayed on its own display unit.

[0050] FIG. 8 is a schematic diagram showing another display example of candidates for the unloading destination. In the display example of FIG. 8, the current position of the transport vehicle is indicated by an icon of a dump truck, and the positions, fees, and CO 2 emission amounts of the candidates for the unloading destination existing around the transport vehicle are superimposed and shown on the map. In the example of FIG. 8, the registered stockyards and the unregistered stockyards are distinguished and shown by letters. Alternatively, they may be distinguished by different display modes such as colors and icons. Also, in the example of FIG. 8, when the construction-generated soil loaded on the transport vehicle is unloaded to each candidate for the unloading destination, the total amount of fees (= unit price × loading amount) that the prime contractor should pay is shown, but the unit price may be shown instead. Also, in the example of FIG. 8, the CO 2 emission amount calculated as described above is also shown. In addition, information such as the name of the operating company, the name of the receiving party, the address of the location, and the usage time may be shown together.

[0051] In the present embodiment, the configuration is such that information is transmitted and received between the prime contractor terminal 100 or the worker terminal 120 and the management server 200, but the transport vehicle may be provided with such a function. That is, when the transport vehicle is provided with an operation unit (input interface) that receives the operation of the worker, a communication unit (communication interface) that transmits and receives various information via the communication network NW1, a display unit (display) that presents necessary information to the user, etc., a search request may be transmitted to the management server 200 through the communication unit of the transport vehicle, and the search result returned from the management server 200 as a result may be displayed on the display unit of the transport vehicle. When the transport vehicle is provided with a load weighing meter, information on the weight of the construction-generated soil measured by the load weighing meter may be notified to the management server 200. Regarding the weight measurement of the construction-generated soil, a configuration disclosed in Patent No. 7208888 or the like can be used to output with high accuracy under various conditions. Further, when the transport vehicle is provided with an imaging device that images the gantry from above, the image obtained by the imaging device may be transmitted to the management server 200.

[0052] (Embodiment 2) In Embodiment 2, a configuration for managing data of a receipt certificate indicating that the unloading destination has received the construction-generated soil will be described. Since the configuration of the information providing system and the configuration of each device are the same as those in the first embodiment, the description thereof will be omitted.

[0053] When an operator managing a stockyard or the like receives construction-generated soil from a prime contractor, the operator issues a receipt indicating that the construction-generated soil has been received. At this time, the operator registers the data of the receipt in the management server 200 together with the contractor ID for identifying the prime contractor and the business ID for identifying the business of the prime contractor.

[0054] FIG. 9 is a flowchart for explaining the registration processing procedure of the receipt in the second embodiment. When receiving construction-generated soil in a stockyard or the like, the operator operating the stockyard or the like issues a receipt. A terminal (for example, the operator terminal 140) used by the operator acquires the data of the receipt (step S201). Here, the data acquired in step S201 may be image data obtained by optically reading a receipt issued as a paper medium. Also, when the receipt is issued as electronic data, the data acquired in step S201 may be the electronic data of the receipt.

[0055] Next, the operator terminal 140 acquires the construction-generated soil ID, the contractor ID, and the business ID (step S202). The construction-generated soil ID is an ID for identifying the construction-generated soil received by the operator, and is set, for example, by the receiving party (operator). Also, the operator terminal 140 inquires of the prime contractor terminal 100 used by the prime contractor that carried out the construction-generated soil or the worker terminal 120 used by the worker via communication about the contractor ID and the business ID, and acquires the contractor ID and the business ID based on the response from the prime contractor terminal 100 or the worker terminal 120. When the contractor ID and the business ID are included in the data of the receipt, the contractor ID and the business ID may be read from the data of the receipt.

[0056] The operator terminal 140 transmits the acquired receipt data, the construction-generated soil ID, the contractor ID, and the business ID to the management server 200 (step S203).

[0057] The management server 200 receives the data of the receipt certificate, the construction-generated soil ID, the contractor ID, and the business ID transmitted from the operator terminal 140 (step S204). The control unit 201 of the management server 200 registers the received receipt certificate data, construction-generated soil ID, contractor ID, and business ID in association with the registration table (step S205). FIG. 10 is a conceptual diagram showing the registration table for receipt certificate data. The registration table is provided in the storage unit 202. In the registration table, the date when the recipient received the construction-generated soil (receipt date), the recipient name, the construction-generated soil ID, the contractor ID, the business ID, and the receipt certificate data (image data or electronic data of the receipt certificate) are stored in association with each other.

[0058] The processes of steps S201 to S205 described above may be executed between the terminal of the recipient (such as the operator terminals 140 and 160) and the management server 200 each time the stockyard or the like receives the construction-generated soil.

[0059] By referring to the registration contents of the registration table, the management server 200 can always grasp, based on the construction-generated soil ID, which contractor is the consignor of the construction-generated soil and which contractor is the recipient of the construction-generated soil.

[0060] When the transport vehicle is equipped with a loading weight meter, the loading weight at the time of loading (the weight after the loading of the construction-generated soil is completed) and the loading weight after unloading may be measured by the loading weight meter, and the information thereof may be transmitted to the management server 200. It is convenient to use the configuration disclosed in Patent No. 7208888 or the like for measuring the loading weight. By acquiring this information, the management server 200 can determine whether the amount of the construction-generated soil loaded on the transport vehicle is equal to the amount of the construction-generated soil unloaded, and can confirm that there is no illegal dumping on the way. When the management server 200 confirms that there is no illegal dumping on the way, the information to that effect may be included in the receipt certificate data.

[0061] (Embodiment 3) In Embodiment 3, a configuration for registering the data of the receipt, the construction-generated soil ID, the contractor ID, and the business ID in the distributed ledger network will be described.

[0062] FIG. 11 is a schematic diagram showing a configuration example of the information providing system according to Embodiment 3. The information providing system according to Embodiment 3 includes a prime contractor terminal 100, a worker terminal 120, operating contractor terminals 140 and 160, and in addition to a management server 200, a distributed ledger network NW2 accessible from the management server 200 or the like. The distributed ledger network NW2 is, for example, a blockchain, and includes a plurality of nodes ND, ND,..., ND that distributively store the information registered from the management server 200.

[0063] Instead of registering the information including the data of the receipt, the construction-generated soil ID, the contractor ID, and the business ID in a registration table in the storage unit 202, the management server 200 broadcasts the information to the plurality of nodes ND, ND,..., ND of the distributed ledger network NW2 and stores it distributively in these nodes ND, ND,..., ND.

[0064] FIG. 12 is a conceptual diagram showing an example of the information held by the node ND of the distributed ledger network NW2. As one of the distributed ledgers, for example, a technology typified by a blockchain can be used. In blockchain technology, transaction information (transaction data) broadcast in the network is approved by one terminal in the network on behalf of others, a block including the transaction information is generated, and registered in the existing blockchain. The fact that there is no fraud in this process is verified by the entire system. In blockchain technology, the reliability of the information exchanged among the participants is ensured by the process of forming a consensus in the network formed by all the participants, and the integrity of the blockchain is maintained by preventing fraud such as tampering and double use throughout the system.

[0065] In this embodiment, as transaction information, data of a receipt certificate when a construction-generated soil is received by a recipient, a construction-generated soil ID, a contractor ID, and a business ID are distributively stored in nodes ND, ND, …, ND of a distributed ledger network NW2. At this time, the management server 200 broadcasts transaction data including the data of the receipt certificate, the construction-generated soil ID, the contractor ID, and the business ID to the nodes ND, ND, …, ND of the distributed ledger network NW2. The broadcast transaction data is approved by one node ND in the distributed ledger network NW2. This node ND generates a block including the transaction data and registers the generated block in the blockchain.

[0066] In FIG. 12, the n-th block represents the last block of the blockchain, and the (n + 1)-th block represents a block being generated that is to be added to the blockchain in which the blocks up to the n-th block are registered. The n-th block includes the hash value of the previous block, a nonce value unique to the block, and the transaction data broadcast from the management server 200.

[0067] When attempting to add a new block to the blockchain in which the blocks up to the n-th block are registered, the node ND performs a calculation (Proof of Work) to obtain a nonce value such that the hash value of the block satisfies a specific condition (for example, the condition that the first k bits of the hash value are 0). The node ND that succeeds in the calculation registers a new block including the hash value of the previous block, the nonce value, and the aforementioned information in the blockchain.

[0068] In Embodiment 3, a form using blockchain as an example of a distributed ledger was described. However, the distributed ledger in which data such as receipt data is registered is not limited to blockchain. For example, instead of proof of work, a distributed ledger using another consensus algorithm such as proof of stake may be used. Even when using other consensus algorithms such as proof of stake, it is possible to achieve the difficulty of predicting the hash value of a block in advance and to ensure the reliability of the system without depending on a specific management entity.

[0069] (Embodiment 4) Regarding the above-described Embodiments 1 to 3, the present invention can be applied to vehicles other than dump trucks that transport construction-generated soil. For example, waste generated in urban areas is loaded at collection sites onto transport vehicles such as garbage collection trucks and transported to relay facilities, waste incineration plants, and the like. Here, the collection site is a place designated in advance where residents dispose of waste. The relay facility is a facility that compresses the garbage collected by the garbage collection truck and transfers it to a large transport vehicle in order to improve the transport efficiency of the waste. A format passing through such a relay facility or a format directly transporting to a waste incineration plant without passing through a relay facility is appropriately selected.

[0070] At a waste incineration plant, in order to grasp and record the amount of carbon dioxide emitted, in addition to managing the types and weights of the waste transported into the waste incineration plant, it is known to grasp the amount of carbon dioxide emissions based on the drive time of the incineration device according to the types and weights. In this case, at the waste incineration plant that is the destination of the transfer, it is possible to grasp the total amount of the waste that is transported and incinerated, but it is difficult to grasp the amount of waste generated in each area that is the source of the transfer because the waste is collected at a plurality of locations during the transportation. In order to skillfully grasp and manage the data regarding this generation amount, it is preferable that it is possible to specifically identify the source of the transfer (the place where the waste is loaded on the transport vehicle and its weight, etc.). Furthermore, by being able to manage the waste collection status by the operator in each area that becomes such a source of the transfer without the residents forgetting to dispose of the waste, it is also possible to improve the reliability regarding the waste collection and transportation operations.

[0071] Therefore, based on information regarding the loading (collection) of waste onto a transport vehicle, it can also be used for information management of unloading destinations such as relay facilities and waste incineration plants, and an information providing system will be described that provides information regarding efficient and reliable loading and transportation in response to various requests.

[0072] FIG. 13 is a schematic diagram showing a configuration example of an information providing system according to Embodiment 4. The information providing system 400 according to Embodiment 4 includes a collection management operator terminal 410 that manages the movement status of a garbage collection vehicle (transport vehicle) 401, an operator terminal 420 related to the transport vehicle 401, operation operator terminals 440 and 460 that manage relay facilities, waste incineration plants, etc., a garbage collection information support device 470 that supports the work of the operator of the transport vehicle 401, and a management server 400S that manages information of each terminal and the like. Note that these terminals, the garbage collection information support device 470, a resident terminal 480 held by a resident living in an urban area, and the management server 400S are communicably connected to each other via a communication network NW4. The communication network NW4 uses a local wireless communication network such as WiFi (registered trademark), or a global wireless communication network such as 3G, 4G, 5G, or LTE.

[0073] The collection management operator terminal 410 is a terminal used by an operator who undertakes the waste collection work. The worker terminal 420 is a terminal used by a worker who actually performs the collection work. The worker terminal 420 may be a terminal owned by the worker himself / herself or a terminal mounted on the transport vehicle 401. The operation operator terminals 440 and 460 are terminals used by the operation operators of the relay facility and the waste incineration plant (final disposal site), respectively. The waste collection information support device 470 includes an imaging device 470C fixed to a utility pole or the like at the collection location. The collection location is set as the imaging area of the imaging device 470C. The imaging device 470C can transmit and receive signals related to imaging. Also, the resident terminal 480 is a terminal owned and used by a resident. The resident can obtain the approach information of the transport vehicle 401 using this resident terminal 480. The management server 400S is an information processing device that centrally manages the information of the unloading destinations including the relay facility and the waste incineration plant based on the information obtained by the transport vehicle 401 and provides information in response to requests from waste collection operators. Note that these terminals and the management server 400S have the same functions and the like as those in the above-described embodiments.

[0074] The imaging device 470C is provided with an imaging communication unit capable of communicating with an information communication unit 4016 of the transport vehicle 401, which will be described later. When the transport vehicle 401 approaches within a predetermined area, an imaging signal for imaging the above-specified location at predetermined intervals is output. The imaging device 470C that receives this imaging signal performs imaging at predetermined time intervals, and the imaging data is output to and stored in the management server 400S.

[0075] The transport vehicle 401 is provided with a dust collection box and a dust input box on a vehicle body (chassis frame) having the longitudinal direction in the vehicle front-rear direction. The opening at the rear of the dust collection box communicates with the opening at the front of the dust input box. The dust input box is pivotally supported by a pivot having the longitudinal direction in the left-right direction at its upper part and is tilted by a tilting cylinder, having a known configuration. Further, the dust input box is provided with a rectangular and open dust input port for dust input at the lower part of its back surface. Above this dust input port, a rear imaging device (in-vehicle camera) having at least a part of the dust input port and a peripheral area in the vicinity thereof as an imaging area is provided. The transport vehicle 401 is provided with a working device 401W (see FIG. 14) for loading and discharging waste. The working device 401W has a dust loading device 401Wa and a dust discharging device 401Wb (see FIG. 14). The dust loading device 401Wa is provided inside the dust input box. The dust loading device 401Wa has a known structure and loads the waste input into the dust input box into the dust collection box.

[0076] A so-called press type is adopted for the dust loading device 401Wa according to the transport vehicle 401 of the present embodiment. This dust loading device 401Wa includes a partition wall provided to be inclined from the front upper end portion to the rear lower end portion of the dust input box, a sliding plate provided to be movable up and down along the partition wall, and a compression plate connected to the lower end portion of the sliding plate and rotatable in the front-rear direction. The dust loading device 401Wa executes an operation including a reverse step in which the compression plate rotates backward, a lowering step in which the sliding plate descends together with the compression plate, a compression step in which the compression plate rotates forward, and a rising step in which the sliding plate rises together with the compression plate as one cycle of operation, thereby compressing the dust input into the dust input box and loading it into the dust collection box (for example, refer to the structure of the dust loading device disclosed in Japanese Patent No. 6888964).

[0077] In addition, the dust and waste discharge device 401Wb has a known structure and discharges the waste contained inside the dust and waste storage box from the dust and waste storage box. A so-called discharge plate type is adopted for the dust and waste discharge device 401Wb according to the transport vehicle 401 of the present embodiment. The dust and waste discharge device 401Wb has a discharge plate provided inside the dust and waste storage box. The discharge plate divides the inside of the dust and waste storage box into a storage area for storing waste on the rear side of the vehicle and a non-storage area where waste is not loaded on the front side of the vehicle. The discharge plate is slidable in the longitudinal direction of the vehicle and slides to the rear side of the vehicle when discharging the waste to discharge the waste in the storage area.

[0078] FIG. 14 is a block diagram showing the configuration of the control system in the transport vehicle 401. The transport vehicle 401 includes a mounting control unit 4011, a mounting storage unit 4012, a mounting operation unit 4013, a mounting input unit 4014, a mounting output unit 4015, an information communication unit 4016, a mounting display unit 4017, a PTO switch 4018, and a maintenance detection unit 4019. The information communication unit 4016 transmits vehicle information including the position, attitude, or weight and loading rate of the loaded waste of the transport vehicle 401 to the management server 400S. The information communication unit 4016 according to the present embodiment is configured to be mounted on the transport vehicle 401, but may be a terminal device such as a smartphone held by a crew member of the transport vehicle 401. In that case, the information communication unit 4016 independently includes a control unit, a storage unit, an operation unit, an input unit, an output unit, a communication unit, and a display unit. Information is transmitted from the management server 400S to each of the terminals 410, 440, 460, 480 and the garbage collection information support device 470 through the information communication unit 4016. Note that the information communication unit 4016 and the worker terminal 420 may be integrated.

[0079] The rack-mounted control unit 4011 includes, for example, a CPU, a ROM, a RAM, etc. The ROM included in the rack-mounted control unit 4011 stores a control program and the like for controlling the operations of the respective hardware components of the transport vehicle 401. The CPU in the rack-mounted control unit 4011 executes the control program stored in the ROM and controls the operations of the respective hardware components, thereby enabling the entire rack-mounted object to function as the transport vehicle 401 of the present disclosure. The RAM included in the rack-mounted control unit 4011 temporarily stores data and the like used during the execution of calculations.

[0080] The rack-mounted storage unit 4012 includes a storage device such as a flash memory. The rack-mounted storage unit 4012 stores various programs executed by the rack-mounted control unit 4011 and data necessary for various processes. Therefore, operation information related to the vehicle, such as the position and loading weight of the transport vehicle 401 described later, is stored.

[0081] The rack-mounted operation unit 4013 is composed of an operation switch and the like and receives operations by an operator. The rack-mounted control unit 4011 executes appropriate control on the sliding plate, the compression plate, the discharge plate, etc. based on the operation received through the rack-mounted operation unit 4013.

[0082] The rack-mounted input unit 4014 includes an interface for connecting various data processing units and sensors. Connected to the rack-mounted input unit 4014 are, for example, a loading position sensor S41 for grasping the positions of the sliding plate and the compression plate, a loading pressure sensor S42 for grasping the pressure applied to the sliding plate and the compression plate, a discharge plate position sensor S43 for grasping the position of the discharge plate, and a discharge plate pressure sensor S44 for grasping the pressure applied to the discharge plate. For example, a proximity sensor for detecting the rod position of a hydraulic cylinder for operating the sliding plate and the compression plate is used as the loading position sensor S41. Also, a hydraulic pressure sensor for detecting the hydraulic pressure value of a hydraulic cylinder for operating the sliding plate, the compression plate, and the discharge plate is used as the loading pressure sensor S42 and the discharge plate pressure sensor S44. Also, an infrared sensor for detecting the distance between the front wall of the dust collection box and the discharge plate is used as the discharge plate position sensor S43.

[0083] In addition, a positioning meter 4014a, a direction meter 4014b, an inclinometer 4014c, a weighing meter 4014d, an object recognition device 4014e, etc. are connected to the mounting input unit 4014. The positioning meter 4014a includes, for example, a GPS receiver, receives radio waves transmitted from GPS satellites, and measures the current position of the transport vehicle 401. The mounting control unit 4011 acquires position information related to the current position of the transport vehicle 401 measured by the positioning meter 4014a through the mounting input unit 4014.

[0084] The direction meter 4014b includes sensors such as a geomagnetic sensor and a gyro sensor, and measures the direction of the transport vehicle 401 (the direction of the transport vehicle 401 in the horizontal plane). The mounting control unit 4011 acquires information related to the direction of the transport vehicle 401 measured by the direction meter 4014b through the mounting input unit 4014.

[0085] The inclinometer 4014c measures the inclination of the transport vehicle 401. The inclinometer 4014c is attached to the truck chassis that supports the dust collection box with the longitudinal direction being the vehicle front-rear direction, and measures the inclination angle (pitch) in the front-rear direction and the inclination angle (roll) in the left-right direction. The inclinometer 4014c attached to the truck chassis measures the inclination angle of the entire vehicle (i.e., the transport vehicle 401). The mounting control unit 4011 acquires information related to the inclination angle of the transport vehicle 401 measured by the inclinometer 4014c through the mounting input unit 4014.

[0086] In the present embodiment, the position of the transport vehicle 401 is measured by the positioning meter 4014a, and the attitude of the transport vehicle 401 is measured by the direction meter 4014b and the inclinometer 4014c. These may be attached to the truck chassis, may be attached to the mounted object, or may be attached to both the truck chassis and the mounted object. That is, the position and attitude of the transport vehicle 401 may be the position and attitude of the mounted object, or may be the position and attitude of the truck chassis.

[0087] The weighing meter 4014d measures the weight of the waste loaded in the dust collection box. The weighing meter 4014d may be provided with a displacement sensor (such as an infrared distance meter) that measures the displacement amount (for example, the distance to the differential gear for the rear wheels of the dust collection box) of a plurality of parts where the load by the loaded object acts, or a load sensor (such as a strain gauge) for measuring the load, in order to measure the weight of the loaded object. Regarding weight measurement, existing methods may be used, but by using the configuration disclosed in, for example, Patent No. 7208888, the weight of the loaded object can be measured with high accuracy under various conditions. The mounting control unit 4011 acquires information related to the weight of the loaded object measured by the weighing meter 4014d through the mounting input unit 4014. The acquired information on the loaded weight is stored in the mounting storage unit 4012.

[0088] The object recognition device 4014e includes the above-described in-vehicle camera that images at least a part of the dust inlet provided in the dust input box and its vicinity, a central processing unit, an image processing unit, and a storage unit. When the dust loading device 401Wa is performing the dust loading operation, there is a risk that an operator who is throwing waste into the dust inlet may be accidentally caught in a compression plate or the like. Therefore, in the transport vehicle 401 according to the present embodiment, the object recognition device 4014e is used to prevent entrapment damage. Specifically, the object recognition device 4014e has a function of collating the features extracted from the object image in the image captured by the in-vehicle camera with the human feature data stored in advance in the storage unit of the object recognition device 4014e to determine whether the object image represents a person. In addition, the object recognition device 4014e also has a function of determining that a person has entered a dangerous area around the dust inlet and its vicinity in the in-vehicle camera image. If the object recognition device 4014e determines that a person has entered a dangerous area around the dust inlet and its vicinity, it transmits the determination result signal to the mounting control unit 4011. The mounting control unit 4011 immediately stops the operation of the dust loading device 401Wa based on the determination result signal. The functions of such an object recognition device 4014e are the same as, for example, the functions disclosed in Patent No. 6938080.

[0089] In the object recognition device 4014e, the in-vehicle camera is installed at a position above the upper part of the back surface of the dustbin, so that a part of the lower dustbin and its vicinity can be imaged. The data of the captured image is used to determine whether a person has entered the dangerous area between the front edge and the rear edge of the dustbin inlet, specifically, whether a part of the human body (such as an arm or a head) has entered the dangerous area.

[0090] The mounting output unit 4015 includes an interface for connecting the working device 401W provided on the transport vehicle 401. The mounting control unit 4011 generates a control signal for controlling the operation of the working device 401W based on the operation information input from the mounting operation unit 4013, the output values from the sensors S41 to S44, the work support information received through the information communication unit 4016, etc., and outputs it to the working device 401W through the mounting output unit 4015.

[0091] The information communication unit 4016 outputs the output signal from the mounting control unit 4011, the vehicle information (operation information) recorded in the mounting storage unit 4012, etc. to an external device and receives the output signal from this external device. That is, it includes a communication interface for transmitting and receiving various data to and from an external device. As the communication interface of the information communication unit 4016, a communication interface compliant with existing communication standards such as WiFi (registered trademark), 3G, 4G, 5G, LTE, etc. can be used. When the data to be transmitted is input from the mounting control unit 4011, the information communication unit 4016 transmits the data to the destination external device, and when it receives the data transmitted from the external device, it outputs the received data to the mounting control unit 4011. The external device includes, in addition to the management server 400S and the transport vehicle 401, the garbage collection information support device 470, etc.

[0092] The mounting display unit 4017 includes a display device such as a liquid crystal monitor. The mounting display unit 4017 displays the information generated by the mounting control unit 4011, the vehicle information (such as the weight and loading rate of the loaded goods) via the working device 401W, and the work support information input from the management server 400S through the information communication unit 4016, etc.

[0093] The PTO switch 4018, when turned on, enables the extraction of the power of the driving source for the traveling of the transport vehicle 401 to operate the working device 401W. The PTO switch 4018 is turned on during the loading operation and turned off during vehicle traveling. That is, the PTO switch 4018 is turned on before the transport vehicle 401 arrives at the collection location and starts the loading operation, and is turned off when the loading operation is completed and the vehicle heads to the next collection location. By measuring the time from when the PTO switch 4018 is turned on to when it is turned off at each collection location, data on the loading operation time at each collection location can be obtained. Also, by summing up the loading operation times at all the collection locations on the collection route, it becomes possible to analyze the time taken from leaving the business office to returning, separated into the traveling time and the loading operation time. In addition, by correlating the operation history of the PTO switch 4018 with the position information history of the position measuring instrument 4014a, it can also be utilized as evidence information for work implementation.

[0094] The maintenance detection unit 4019 has a function of extracting, as maintenance information, the necessary part for maintenance from among the operation histories of each part of the working device 401W, the operation history of the PTO switch 4018, the operation history of the mounting operation unit 4013, the operation histories of the position measuring instrument 4014a, the azimuth meter 4014b, the inclinometer 4014c, the weighing meter 4014d, the object recognition device 4014e, the loading position sensor S41, the loading pressure sensor S42, the discharge plate position sensor S43, and the discharge plate pressure sensor S44, as well as the operation histories of other maintenance sensors (not shown). Examples of the maintenance sensors include an operating oil temperature sensor for the hydraulic actuator that drives the working device 401W, a hydraulic relief count measurement sensor for the working device 401W, a loading cycle time measurement sensor for the dust loading device 401Wa, a temperature sensor for the in-vehicle fire detection device, and the like.

[0095] When the transport vehicle 401 is in the EV (Electric Vehicle) format, it is preferable to include a remaining battery level sensor. The maintenance information extracted by the maintenance detection unit 4019 can be used for early detection of abnormal conditions in each part of the transport vehicle 401, estimation of the maintenance time, and optimization of the collection route. It also leads to an improvement in work efficiency in the operation management by the collection management operator. During the operation of the transport vehicle 401, the maintenance detection unit 4019 appropriately extracts the operation history and the operation history of each part and stores them as maintenance information in the mounted storage unit 4012. The maintenance information stored in the mounted storage unit 4012 is transmitted to the management server 400S, the collection management operator terminal 410, and the worker terminal 420 through the information communication unit 4016 in response to a request from any of them.

[0096] Figure 15 is a block diagram for explaining the internal configuration of the management server 400S. The management server 400S is a dedicated or general-purpose computer and includes a server control unit 401S, a server storage unit 402S, a server communication unit 403S, a server input unit 404S, and a server learning unit 405S.

[0097] The server control unit 401S includes, for example, a CPU, a ROM, a RAM, etc. In the ROM included in the server control unit 401S, a control program for controlling the operation of each part of the hardware included in the management server 400S and the like are stored. The CPU in the server control unit 401S executes the control program stored in the ROM and the work support program stored in the server storage unit 402S, and controls the operation of each part of the hardware, thereby causing the entire device to function as the management server 400S of the present disclosure. In the RAM included in the server control unit 401S, data and the like used during the execution of the calculation are temporarily stored.

[0098] The server control unit 401S may be one or more control circuits or arithmetic circuits including a GPU, an FPGA, a volatile or non-volatile memory, etc., not limited to the above configuration. Further, the server control unit 401S may have functions such as a clock that outputs date and time information, a timer that measures the elapsed time from when a measurement start instruction is given until a measurement end instruction is given, and a counter that counts numbers.

[0099] The server storage unit 402S includes a storage device such as an HDD or an SSD. The server storage unit 402S stores various computer programs executed by the server control unit 401S and data necessary for various processes.

[0100] The computer programs stored in the server storage unit 402S also include a work support program that generates work support information for the transport vehicle 401 based on the information of the collection location. These computer programs may be a single computer program or a program group composed of a plurality of computer programs. Further, the computer programs stored in the server storage unit 402S may partially use existing libraries. The computer program may be executed by a single computer or may be executed in cooperation by a plurality of computers.

[0101] The server communication unit 403S includes a communication interface for transmitting and receiving various data to and from an external device. As the communication interface of the server communication unit 403S, a communication interface compliant with existing communication standards such as WiFi (registered trademark), 3G, 4G, 5G, and LTE can be used. When the data to be transmitted is input from the server control unit 401S, the server communication unit 403S transmits the data to the destination external device, and when receiving data transmitted from the external device, outputs the received data to the server control unit 401S. The external device is, in addition to the transport vehicle 401, a garbage collection information support device 470 or the like.

[0102] The server input unit 404S includes, for example, an interface for connecting the garbage collection information support device 470. The garbage collection information support device 470 receives the position information of the transport vehicle 401 transmitted from the information communication unit 4016 of the transport vehicle 401, drives the imaging device 470C to start imaging a preset area (the place where residents place waste), and outputs the imaging result.

[0103] The server learning unit 405S is provided to derive an appropriate collection route and the appropriate number of transport vehicles 401 based on various information transmitted from the information communication unit 4016 of the transport vehicle 401 by machine learning or deep learning. For example, the server learning unit 405S learns the tendency of how much the loading operation time at each collection location, which is derived from the on / off information of the PTO switch 4018, varies depending on the season. Then, for each of the multiple collection routes in a day, the total working time required for operation is analyzed and calculated, including not only the driving distance but also the loading operation time. And for all of the multiple collection routes, the collection routes are optimized seasonally so that the total working time in a day becomes equal. Existing technologies known in VRP (Vehicle Routing Problem) etc. may be used for the optimization of the collection route.

[0104] Also, it is preferable that the server learning unit 405S learns the relationship between the amount of waste before the loading operation obtained from the imaging data by the imaging device 470C of the garbage collection information support device 470 and the actual loading operation time taken to load that amount onto the transport vehicle 401. By performing learning in advance based on past information, it is possible to predict the loading operation time at each collection location on the day of garbage collection by the transport vehicle 401 from the imaging data imaged by the imaging device 470C of the garbage collection information support device 470 at each collection location on that day.

[0105] In the present embodiment, the management server 400S may be a single computer or a computer system composed of a plurality of computers, peripheral devices, and the like. Further, the management server 400S may be a virtual machine whose entity is virtualized or a cloud.

[0106] Although not shown in the figure, the garbage collection information support device 470 includes a support information communication unit in the same manner as the information communication unit 4016 related to the transport vehicle 401. The support information communication unit mainly receives a drive signal of the imaging device 470C from the management server 400S and transmits imaging data obtained by the imaging device 470C. The support information communication unit according to the present embodiment is configured to be installed on a utility pole together with the imaging device 470C, but may be a terminal device such as a smartphone held by a passenger of the transport vehicle 401. Information is transmitted from the management server 400S to each of the terminals 410, 440, 460, 480 and the garbage collection information support device 470 through the support information communication unit.

[0107] Next, a work management method for collecting, transporting, and discharging waste using the transport vehicle 401 according to the present embodiment will be described. FIGS. 16A and 16B are flowcharts for explaining the procedure of processing executed by the transport vehicle 401, the management server 400S, the garbage collection information support device 470, and the resident terminal 480. During the operation of the transport vehicle 401, it is assumed that a communication connection is established between the transport vehicle 401 (information communication unit 4016) and the management server 400S, and an information providing system 400 is constructed between these transport vehicles 401 and the management server 400S.

[0108] The information communication unit 4016 mounted on the transport vehicle 401 establishes communication with the management server 400S at the start point of the collection route (step S401).

[0109] During the operation of the collection route, the mounting control unit 4011 of the transport vehicle 401 detects the position of the transport vehicle 401 through the positioning meter 4014a at a predetermined time interval (step S402). At this time, the attitude of the transport vehicle 401 is also detected through the azimuth meter 4014b and the inclinometer 4014c (step S403). In this flowchart, for the sake of convenience, the procedure for detecting the position, attitude (azimuth and inclination) of the transport vehicle 401 is adopted in this order. However, these procedures may be in reverse order or may be carried out simultaneously.

[0110] The mounting control unit 4011 reads out the information regarding the loading weight of the transport vehicle 401 stored in the mounting storage unit 4012 as weight information (step S404). The mounting control unit 4011 transmits vehicle information including the detected information such as the position of the transport vehicle 401 and the weight information of the transport vehicle 401 read from the mounting storage unit 4012 to the information providing system 400 as vehicle information before the operation of the loading device (step S405). Specifically, the mounting control unit 4011 transmits this information to the management server 400S through the information communication unit 4016.

[0111] The server control unit 401S of the management server 400S receives the vehicle information transmitted from the information communication unit 4016 from the server communication unit 403S (step S406). The server control unit 401S specifies the positional relationship between the predetermined collection location of the waste and the transport vehicle 401 based on the vehicle information received in step S406 (step S407).

[0112] Based on the identified positional relationship, specifically based on the fact that the transport vehicle 401 has approached the desired distance, the server control unit 401S transmits the approach information of the transport vehicle 401 to the resident terminal 480 (step S408). With this information, if a resident has forgotten to take out the waste, the resident can recognize that they need to take out the waste to a predetermined location (collection location) before the transport vehicle 401 passes, such as immediately taking out the waste. In order to transmit the approach information to the residents, the correspondence relationship between a predetermined collection location and the residents who take out waste at that collection location is grasped by the management server 400S in advance. Specifically, a list of the correspondence relationship between the position and identification number of a predetermined collection location and the identification code, telephone number, email address, or SNS, etc. of a predetermined resident is stored in advance in the server storage unit 402S. Based on the information stored in the server storage unit 402S, when the transport vehicle 401 approaches a predetermined collection location, the server control unit 401S transmits the approach information to the residents corresponding to that collection location.

[0113] Note that the timing of transmitting the approach information is not limited to only the timing when the transport vehicle 401 approaches the collection location closest to it. The timing when the transport vehicle 401 approaches a collection location several stops ahead is also conceivable. For example, a resident who is designated to take out waste at the first collection location can receive the approach information when the transport vehicle 401 approaches the fourth collection location, which is separated from the first collection location by the second and third collection locations. With such a configuration, even if a resident has forgotten to take out the waste, they can take out the waste to the first collection location with a certain degree of leeway. Also, as the approach information, each time the transport vehicle 401 approaches a collection location closer to the first collection location, such as the fourth collection location, the third collection location, and the second collection location, it is also preferable to transmit to the residents the approach information "It has come to the collection location ○ stops ahead" or to transmit the magnitude of the approach distance.

[0114] Also, it is preferable that the approach information includes the estimated arrival time of the transport vehicle 401. The estimated arrival time is a prediction of how much time the transport vehicle 401 will take to arrive at the collection location (referred to as the arrival collection location) associated with the resident who receives the approach information at the resident terminal 480. For example, when the approach information is transmitted to the resident when the transport vehicle 401 approaches the collection location three locations ahead, the estimated arrival time is predicted by adding the estimated travel time from the current location of the transport vehicle 401 to the arrival collection location and the estimated total loading operation time. The estimated travel time is the value obtained by dividing the distance from the current location of the transport vehicle 401 to the arrival collection location by the average vehicle speed of the transport vehicle 401. Also, the estimated total loading operation time is the sum of the estimated loading operation times at three locations during the period from the current location of the transport vehicle 401 to the arrival collection location. Note that the transmission of the approach information is also effective when it is desired to take the waste to the predetermined collection location as close as possible to the collection time. If the waste is taken to the predetermined collection location too early, crows or the like may scatter the waste before collection. On the other hand, while waiting for the approach of the transport vehicle 401 to take out the waste just before collection, the transport vehicle 401 may arrive at the predetermined collection location earlier than expected, and the collection may end before the waste is taken out. By transmitting the approach information, the timing of the arrival of the transport vehicle 401 at the predetermined collection location can be known, so it is possible to prevent the waste from being left uncollected while suppressing damage caused by crows or the like.

[0115] Next, the server control unit 401S generates work support information for the garbage collection information support device 470 (step S409). The server control unit 401S generates, for example, a control command including a control value for driving the imaging device 470C as the work support information. The server control unit 401S transmits the generated work support information to the garbage collection information support device 470 (step S410).

[0116] The garbage collection information support device 470 receives the work support information transmitted from the management server 400S at the support input unit (step S411), and the support control unit drives the imaging device 470C to image the garbage collection location at a predetermined angle (step S412). Then, the support communication unit transmits the imaging data obtained by the imaging device 470C to the management server 400S (step S413). By storing the imaging data obtained by the imaging device 470C in the server storage unit 402S of the management server 400S, it becomes possible to check the garbage accumulation status at the collection location when the transport vehicle 401 approaches. In addition, in order to check the garbage accumulation status in this way, the transmission and reception in steps S409 to S413 are performed. Therefore, it is preferable to perform the transmission in step S410 for the garbage collection information support device 470 at the collection location closest to the transport vehicle 401. This is because the garbage accumulation status immediately before the loading operation can be checked.

[0117] When the transport vehicle 401 arrives at the collection location or its vicinity and stops, the operator turns on the PTO switch 4018 of the transport vehicle 401. As a result, the working device 401W becomes operable. The mounting control unit 4011 recognizes that the PTO switch 4018 has been turned on. The operator picks up the garbage placed at the collection location and throws it into the garbage inlet of the transport vehicle 401. When the garbage is thrown in and the mounting operation unit 4013 is operated, the garbage loading device 401Wa (such as a sliding plate or a compression plate) of the transport vehicle 401 operates. At this time, the mounting control unit 4011 recognizes the driving state such as the number of loading times and the loading load based on the detection contents of the loading position sensor S41, the loading pressure sensor S42, the discharge plate position sensor S43, and the discharge plate pressure sensor S44 (step S414). In addition, when the garbage loading device 401Wa is operated, the mounting control unit 4011 detects the position of the transport vehicle 401 through the position meter 4014a (step S415), and also detects the attitude of the transport vehicle 401 through the azimuth meter 4014b and the inclinometer 4014c (step S416).

[0118] The mounting control unit 4011 transmits vehicle information including information such as the fact that the PTO switch 4018 has been turned on and the position of the transport vehicle 401 detected by each sensor, as vehicle information during the operation of the loading device, to the management server 400S through the information communication unit 4016 (step S417). Note that the mounting control unit 4011 may measure the weight of the waste loaded in the dust collection box by the weighing scale 4014d each time the dust collection device 401Wa operates and stops while the PTO switch 4018 is on. Then, this weight information may be included in the vehicle information during the operation of the loading device. In this case, it is possible to measure the change in the detailed loading weight within one collection location.

[0119] The server control unit 401S of the management server 400S receives the transmitted vehicle information through the server communication unit 403S (step S418). Based on the received vehicle information, the server control unit 401S transmits to the resident terminal 480 the fact that the dust collection device 401Wa of the transport vehicle 401 is in operation (step S419). With this information, the resident can grasp whether the transport vehicle 401 is simply parked at the collection location or is in the loading operation. As a specific content for displaying on the display unit of the resident terminal 480 that the dust collection device 401Wa of the transport vehicle 401 is in operation, for example, a simple display with "loading operation in progress" superimposed on the icon of the dust collection vehicle may be used, or an animation showing the operator throwing garbage into the dust inlet may be displayed.

[0120] In addition, when the waste loading device 401Wa of the transport vehicle 401 is in operation, if there is a difference between the current position of the transport vehicle 401 and the current collection location, it can be determined that the operator has left the transport vehicle 401 (run) and approached the collection location, and the operator has carried the waste to the transport vehicle 401. Also, for example, when the operator terminal 420 held by the operator is a mobile terminal and is configured to perform short-range wireless communication connection with the transport vehicle 401, the position information can be transmitted from the operator terminal 420 to the management server 400S. Based on the position information from this operator terminal 420, the server control unit 401S of the management server 400S can also determine the current collection location of the operator. Further, based on the difference between the position information from the operator terminal 420 and the position information from the transport vehicle 401, the server control unit 401S can also determine whether the operator has run from the transport vehicle 401 and approached the collection location. Also, the server control unit 401S can obtain information from the transport vehicle 401 on whether the short-range wireless communication with the operator terminal 420 has been disconnected, and thereby determine whether the operator is at a collection location that is a certain distance away from the transport vehicle 401.

[0121] After the operator finishes a set of waste loading operations with the transport vehicle 401 stopped, the operator turns off the PTO switch 4018 of the transport vehicle 401. The mounting control unit 4011 recognizes that the PTO switch 4018 has been turned off. Also, based on the detection contents of the loading position sensor S41, the loading pressure sensor S42, the discharge plate position sensor S43, and the discharge plate pressure sensor S44, the mounting control unit 4011 recognizes the driving state such as the number of loading operations and the loading load (step S420). Also, the mounting control unit 4011 detects the position of the transport vehicle 401 through the position meter 4014a (step S421), and also detects the attitude of the transport vehicle 401 through the azimuth meter 4014b and the inclinometer 4014c (step S422)

[0122] The vehicle-mounted control unit 4011 measures the weight of the waste loaded in the dust collection box by the weighing scale 4014d. Then, it stores the information on the latest loaded weight obtained in the vehicle-mounted storage unit 4012. The vehicle-mounted control unit 4011 reads out the information on the latest loaded weight of the transport vehicle 401 stored in the vehicle-mounted storage unit 4012 and the information on the past loaded weights as weight information (step S423). Note that by taking the difference between the latest loaded weight and the nearest past loaded weight, the weight of the waste loaded while the transport vehicle 401 is stopped can be calculated. The vehicle-mounted control unit 4011 transmits vehicle information including the fact that the PTO switch 4018 has been turned off, information such as the position of the transport vehicle 401 detected by each sensor, and the weight information of the transport vehicle 401 read from the vehicle-mounted storage unit 4012 to the information providing system 400 as vehicle information after the loading device operates (step S424). Specifically, the vehicle-mounted control unit 4011 transmits this information to the management server 400S through the information communication unit 4016. In addition, the operating status of the automatic opening and closing door provided at the dust inlet may be added to the vehicle information as supplementary information on the completion of the work.

[0123] The server control unit 401S of the management server 400S receives the vehicle information transmitted from the information communication unit 4016 from the server communication unit 403S (step S425). The server control unit 401S of the management server 400S can determine whether the loading work has been completed at a predetermined collection location based on the received vehicle information. Then, based on the determination that the loading work has been completed at a predetermined collection location, the server control unit 401S transmits to the target resident terminal 480 the fact that the waste collection by the transport vehicle 401 has been completed at the predetermined collection location (step S426). With this information, the resident can recognize that the waste collection has been completed. Further, the server control unit 401S generates work support information for the garbage collection information support device 470 (step S427). The server control unit 401S generates, for example, a control command including a control value for driving the imaging device 470C as the work support information. The server control unit 401S transmits the generated work support information to the garbage collection information support device 470 (step S428).

[0124] The garbage collection information support device 470 receives the work support information transmitted from the management server 400S at the support input unit (step S429), and the support control unit drives the imaging device 470C to image the garbage collection location at a predetermined angle (step S430). Then, the support communication unit transmits the imaging data obtained by the imaging device 470C to the management server 400S (step S431). By storing the imaging data obtained by the imaging device 470C in the server storage unit 402S of the management server 400S, it becomes possible to confirm the remaining status of the garbage at the collection location after the transport vehicle 401 has moved. Therefore, for the collection management operator and the garbage collection worker, it becomes automatically possible to accurately record the situation where the garbage has been collected. That is, by acquiring the images before and after collection together with the location where the transport vehicle 401 has moved and the movement time, it is possible to clearly indicate that the garbage at the collection location has been reliably collected. Note that it may be in a form where only one of the images before and after collection is acquired. After step S431, the steps of S402 to S431 are repeated for the number of collection locations on the collection route.

[0125] The information communication unit 4016 may estimate the loading state of the garbage loaded in the dustbin and transmit vehicle information further including the information on the estimated loading state to the management server 400S. The loading state represents the weight of the garbage in the dustbin and the ratio (loading rate) of the garbage occupying the inside of the dustbin. The method for estimating the loading state is not limited to a specific method, but instead of, or in addition to, using the weighing scale 4014d, a method of calculating using the hydraulic pressure value detected by the loading pressure sensor S42 may be adopted. Regarding the loading rate, a method of calculating based on the number of loading cycles of the garbage loading device 401Wa detected by the loading position sensor S41 is conceivable. Also, a method of calculating the loading rate using the position of the discharge plate detected by the discharge plate position sensor S43 or the hydraulic pressure value detected by the discharge plate pressure sensor S44 is also conceivable. Furthermore, a method of calculating using the aforementioned position and hydraulic pressure value and displaying as shown in FIG. 17 may be adopted.

[0126] In particular, when displaying as shown in Fig. 17, regarding the loading rate at the timing near the expiration value and the loading rate close to the timing of the start of loading, it is possible to detect the loading rate with relatively high accuracy even by the position of the discharge plate and the hydraulic pressure value. On the other hand, at the intermediate timing between the two timings, in addition to the position of the discharge plate and the hydraulic pressure value, the accuracy of the loading rate can also be improved by using the calculated values based on the number of loading cycles of the dust loading device 401Wa and the hydraulic pressure value described above. Also, regarding the estimation (calculation) of the loading rate, the accuracy can be improved by using the object recognition device 4014e in other ways. Specifically, the object recognition device 4014e has a waste verification unit that verifies the features extracted from the object image in the image captured by the in-vehicle camera against the waste feature data stored in advance in the storage unit of the object recognition device 4014e to determine whether the object image represents waste. The object recognition device 4014e also has an input determination unit that determines whether the object image determined to be waste by the waste verification unit has been input into the dust bin. The object recognition device 4014e also has a count unit that counts the number of wastes determined to have been input into the dust bin by the input determination unit. Furthermore, the object recognition device 4014e has a volume determination unit that determines the volume of the waste determined to have been input into the dust bin by the input determination unit. Such functions can apply the means for measuring the number of wastes as disclosed in Japanese Patent No. 7026540. In this case, the amount loaded in the dust collection bin can be determined according to the results calculated by the count unit and the volume determination unit.

[0127] The information and communication unit 4016 acquires data on the loading weight and loading rate of the waste in the above-described dustbin, and transmits vehicle information including such information to the management server 400S. In this case, the management server 400S can appropriately output such vehicle information to the operator terminals 440 and 460 of relay facilities, waste treatment plants, etc. At relay facilities and waste treatment plants, based on the position information of the transport vehicle 401, the time zone when the waste is transported and discharged (arrives) by the transport vehicle 401, and the amount of waste to be discharged can be confirmed early, which is preferable in their operation management. Also, the management server 400S outputs such vehicle information to the collection management operator terminal 410. In this case, the collection management operator can output, via the collection management operator terminal 410, changes to the collection route according to the collection status in the urban area to the transport vehicle 401 (worker terminal 420). In particular, regarding the information on the displayable loading rate, since the amount of waste placed at the collection location is not precisely grasped in advance, the determination method described above is also applicable to the loading rate of the dustbin.

[0128] Transmission by the information communication unit 4016 to the above-described operator terminals 440 and 460 and the collection management operator terminal 410 is performed in response to a waste transportation request. The waste transportation request according to the present embodiment refers not only to a request by direct operation of an operator or a collection management operator, but also to a state in which the operator terminals 440 and 460 and the collection management operator terminal 410 are connected to the information providing system 400 in order for the operator or the collection management operator to check the information of the transportation vehicle 401. Then, the collection management operators refer to the operation information of the transportation vehicle 401 on the day. For example, if there is a transportation vehicle 401 whose loading rate has become higher earlier than usual, they can change another transportation vehicle 401 with a margin in the loading rate from the original assumed route (collection route) and allocate it as support for the transportation vehicle 401 whose loading rate has become higher earlier than usual. At this time, the collection management operator can use the collection management operator terminal 410 to output the instruction to the worker terminal 420 held by the worker of the transportation vehicle 401 to be supported. In this way, it becomes possible to flexibly change the collection route within a day. When changing the assumed route, in addition to the loading rate, the relationship between the outer dimensions of the transportation vehicle 401 and the road dimensions included in the collection route may be considered. For example, in addition to the total vehicle length, vehicle width, and vehicle height of the transportation vehicle 401, the road width and the passable vehicle height of the road included in the collection route are stored in advance in the management server 400S. In particular, by being able to grasp or select a transportation vehicle 401 that can pass without problems regarding the road width and vehicle height, it helps to provide a good operation environment and conditions for the transportation vehicle 401 and the residents even when the collection route is changed.

[0129] And, as in this embodiment, by recording the work data at the collection location and making the data in an outputtable form, it is possible to classify, grasp, and manage the amount of waste in the urban area. At the relay facility and the waste incineration plant, a large number of transport vehicles 401 bring in waste, and it is possible to grasp the amount of waste brought in. However, it is difficult to grasp how much waste has been transported from which area. According to this embodiment, in addition to the drive data of the above-described garbage loading device 401Wa and garbage discharge device 401Wb (detection values by each sensor S41 to S44), by using measurement values of the position meter 4014a and the weighing meter 4014d, etc., it is possible to acquire data for each area from the transport vehicle 401. By recording how much waste is collected at which location by the transport vehicle 401 moving through the urban area in this way, it is also possible to utilize it for grasping and managing how many transport vehicles 401 are required for each collection route or how many workers are required, which leads to an improvement in work efficiency and an effective utilization of labor force, so it is preferable.

[0130] As in this embodiment, by using the transport vehicle 401 to make it possible to acquire data such as the location, time, and amount related to the collection of waste, it can also be utilized for supporting the local residents. For example, in an area where elderly people gather, by grasping the presence or absence of waste and the number of waste items (the number of garbage bags), it can also be used as a tool for confirming changes in the living environment in that area (for example, the number of garbage bags is less than usual).

[0131] In this embodiment, the configuration for managing the data of the receipt certificate according to Embodiment 2 can also be applied to the relay facility and the waste incineration plant.

[0132] The operating entity that manages relay facilities and waste incineration plants registers the data of the receipt certificate in the management server 400S together with the operator ID that identifies the collecting entity and the service ID that identifies the services of the collecting entity. When the transport vehicle 401 accepts the waste to be transported, the operating entity issues a receipt certificate, and the terminal used by the operating entity (for example, the operator terminal 460) acquires the data of the receipt certificate. Here, the data to be acquired may be image data obtained by optically reading the receipt certificate issued as a paper medium. Also, when the receipt certificate is issued as electronic data, the data to be acquired may be the electronic data of the receipt certificate.

[0133] Next, the operator terminal 460 acquires the waste ID, operator ID, and service ID. Here, the waste ID is an ID that identifies the accepted waste and is set, for example, by the receiving party (operating entity). Also, the operator terminal 460 inquires of the collection management operator terminal 410 used by the collection management entity that carried out the waste or the worker terminal 420 used by the worker about the operator ID and service ID via communication, and acquires the operator ID and service ID based on the response from the collection management operator terminal 410 or the worker terminal 420. When the operator ID and service ID are included in the data of the receipt certificate, the operator ID and service ID may be read from the data of the receipt certificate.

[0134] The operator terminal 460 transmits the data of the received receipt, the waste ID, the operator ID, and the business ID to the management server 400S, and the management server 400S receives the data of the receipt certificate, the waste ID, the operator ID, and the business ID transmitted from the operator terminal 460. The server control unit 401S of the management server 400S registers the received data of the receipt certificate, the waste ID, the operator ID, and the business ID in association with the registration table. The registration table is provided in the server storage unit 402S. In the registration table, the date when the recipient received the waste (receipt date), the recipient name, the waste ID, the operator ID, the business ID, and the data of the receipt certificate (image data or electronic data of the receipt certificate) are stored in association. These processing operations and controls may be executed between the terminal of the recipient (such as the operator terminals 440 and 460) and the management server 400S each time the waste is received at a waste incineration plant or the like.

[0135] By referring to the registration content of the registration table, the management server 400S can grasp at any time which operator is the source of the waste and which operator is the recipient of the waste, using the waste ID as a clue. At a waste incineration plant or the like, various monitors are carried out during the processing process of the transported waste, and the sorting status of the waste and the mixing of flammable substances are also grasped and managed. Therefore, by obtaining these IDs, it is possible to identify a transport vehicle 401 that transports insufficiently sorted waste, a transport vehicle 401 that transports waste with a large amount of flammable substances mixed in, and the like. As a result, it is also possible to effectively raise awareness in the area where such a transport vehicle 401 is responsible for collection.

[0136] Since the vehicle information including the amount of waste loaded on the transport vehicle 401 can be output, it is also possible to transmit the information on the loading weight at the time of loading and the loading weight after unloading to the management server 400S. By obtaining this information, the management server 400S can determine whether the amount of waste loaded on the transport vehicle 401 is equal to the amount of waste unloaded, and can also confirm that there is no illegal dumping on the way. When the management server 400S confirms that there is no illegal dumping on the way, it may include information to that effect in the data of the receipt certificate.

[0137] In this embodiment, the garbage collection information support device 470 is configured to include an imaging device 470C fixed to a utility pole or the like at the collection location. However, the present invention is not limited to this configuration, and any other configuration that can image the collection location before and after waste collection is applicable. For example, as shown in FIG. 18, it may be configured to include an imaging device 470Ca fixed to a protective cap H (helmet or hat) worn by an operator on the head. The imaging device 470Ca is provided with a function for recognizing the operator's gestures. In this embodiment, when the operator places the waste to be imaged within the imaging range of the imaging device 470Ca and makes a predetermined gesture within the imaging range at the collection location, the imaging device 470Ca executes imaging. For example, as shown in FIG. 19, when the operator makes a gesture G of forming a camera frame with both hands toward the collection location S, the content of the gesture G is recognized by image recognition and imaging is executed. The type of gesture G is not particularly limited, and various gestures such as repeatedly opening and closing the hand multiple times can be applied. In addition, the execution of imaging by the imaging device 470Ca is not limited to that performed by the gesture G, and it may be performed by voice recognition. Note that the above-described rear imaging device (in-vehicle camera) may be used as a device for imaging the collection location before and after waste collection. By using the image of the rear imaging device, it is possible to prevent the operator from being involved and leave evidence of waste collection.

[0138] The purpose of using the imaging device 470Ca fixed to the protective cap H is to enable imaging to be performed at a position closest to the waste to be collected and with the best visibility without the operator directly touching the imaging device 470Ca with the hand. Regarding the timing of executing imaging with the imaging device 470Ca, it is preferable to acquire an image of the collection location at at least two timings, namely, the timing when the operator starts removing the waste and the timing when the removal is completed. In order to prevent the operator from forgetting to image, when the dust loading device 401Wa is cycled by operating the mounting operation unit 4013 provided in the transport vehicle 401, or when it is automatically imaged a predetermined time before and after the operation of the mounting operation unit 4013.

[0139] The embodiments disclosed this time should be considered illustrative in all respects and not restrictive. The scope of the present invention is shown not by the above description but by the claims, and it is intended that all modifications within the meaning and scope equivalent to the claims be included.

[0140] In each of the above-described embodiments, the transport vehicle has been described as a dump truck or a garbage collection vehicle. Regarding the application of the present invention, as long as it has a configuration capable of outputting vehicle information in the same manner as the above-described embodiments, it is not limited to these vehicles, and other special vehicles (such as liquid transport vehicles, powder and granular transport vehicles, water supply vehicles, sprinkler trucks, mixer trucks, tanker lorries, suction vehicles, high-pressure cleaning vehicles, vehicle transport vehicles, road maintenance workers, vehicles with load platform lifting devices, etc.) may also be used.

[0141] Particularly, for any special vehicle, since vehicle information such as the position and weight of the transport vehicle can be output as operation information, this operation information can be skillfully utilized and can also be used for driving control of external devices by cooperating with external devices. Therefore, with a configuration capable of outputting the operation information according to the present invention, it is possible to lead to suppression of labor costs and improvement of work efficiency in various broad business scopes using special vehicles.

[0142] In addition, with a configuration capable of outputting the above operation information, the convenience of business management is also improved. It is possible to grasp and manage not only the electronic management of the actual business situation but also the actual driving route and distance of the transport vehicle, the number of collections of waste, etc. for each collection location, and the weight of the collected waste, so that the workload of each operator can also be specifically grasped. Therefore, in the form where the business consideration is based on a percentage system, it is also helpful to accurately and simply calculate the consideration using the output data according to the present invention.
