DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] An integrated fleet management system according to an embodiment will be described in detail below with reference to the drawings. However, the scope of the invention is not limited thereto.

[0009] [Overview of the integrated fleet management system] FIG. 1 is a diagram showing a schematic configuration of an integrated fleet management system 1 according to this embodiment. The integrated fleet management system 1 is a management system that links appropriate management of transport vehicles for construction work (so-called fleet management) with a payload system mounted on construction machinery used in the construction work.

[0010] The integrated fleet management system 1 includes a construction machine 100, an operator terminal 200, a transport vehicle 300, a management server 400, and the like. The construction machine 100, the operator terminal 200, and the management server 400 are connected via a communication network N. The transport vehicle 300 is equipped with a beacon transmitter (e.g., an iBeacon (registered trademark) transmitter) BT that transmits a beacon signal by BLE (Bluetooth Low Energy). The beacon signal includes ID information (e.g., UUID, etc.) for identifying the transport vehicle 300 equipped with the beacon transmitter BT that transmitted the signal. The beacon signal transmitted from the beacon transmitter BT is received by the nearby construction machine 100. The number of the construction machines 100, the operator terminals 200, the transport vehicles 300, and the like is not particularly limited.

[0011] The communication network N includes a communication network capable of transmitting and receiving information between the construction machine 100, the operator terminal 200, and the management server 400. The communication network N may be, for example, a mobile communication network conforming to LTE, 4G, 5G, etc., WiFi (Wireless Fidelity), the Internet, an in-house network, a LAN, a dedicated line, a telephone line, Bluetooth (registered trademark), other communication lines, or a combination thereof, regardless of whether the communication network is wired or wireless.

[0012] The construction machine 100 is a machine used in civil engineering and construction work, such as an excavator (shovel) that excavates and loads earth and sand. The construction machine 100 is equipped with a payload system 110 that measures various information related to the load, such as the load of the cargo and the number of loads (hereinafter also referred to as "payload").

[0013] The payload system 110 includes a measurement unit 111 that measures the loading load and number of loadings by the construction machine 100 and outputs the measurement results as payload information, an operation button group 112 for instructing the start and end of payload measurement, and a communication unit 113 that transmits the generated payload information to the operator terminal 200. The operation button group 112 includes at least a start button B1 that instructs the start of payload measurement and an end button B2 that instructs the end of payload measurement. The communication unit 113 includes a CAN-WiFi converter CO for transmitting CAN (Controller Area Network) information used by the construction machine 100 to the operator terminal 200 via wireless LAN (WiFi). When the communication unit 113 receives CAN information (here, payload information) from the measurement unit 111, the communication unit 113 wirelessizes the CAN communication using the CAN-WiFi converter CO and transmits it to the operator terminal 200.

[0014] The operator terminal 200 is a terminal, such as a tablet terminal, used by an operator who operates the construction machine 100. The operator terminal 200 is not limited to a tablet terminal, and may be, for example, a smartphone, a wearable terminal, a notebook PC (Personal Computer), a PC terminal, or other terminal device.

[0015] An application (hereinafter also referred to as a "client application") AP is installed on the operator terminal 200 for displaying payload information of the construction machine 100 operated by the operator and for selecting the transport vehicle 300 onto which the construction machine 100 will load cargo. The client application AP may be configured such that some or all of its functions are provided via the communication network N (so-called SaaS (Software as a Service) or the like). The operator terminal 200 may be installed in advance on each construction machine 100, or may be configured so that each operator can carry it with them.

[0016] The transport vehicle 300 is a vehicle onto which the construction machine 100 loads cargo, and may be, for example, a dump vehicle. The transport vehicle 300 is not limited to a dump vehicle, and may be any vehicle capable of transporting construction-related goods. Construction-related goods may include goods carried in and out of a construction site, such as construction soil, construction by-products, ready mixed concrete, asphalt, and construction materials and equipment. Of course, construction-related goods are not limited to these.

[0017] As already explained, the transport vehicle 300 of this embodiment is equipped with a beacon transmitter BT that transmits a beacon signal including ID information, and the beacon signal transmitted from the beacon transmitter BT is received by a nearby construction machine 100.

[0018] That is, a beacon receiver BR is mounted on each construction machine 100 so that it can receive a beacon signal transmitted from a beacon transmitter BT of a nearby transport vehicle 300. When the beacon receiver BR of the construction machine 100 receives a beacon signal from one or more nearby transport vehicles 300, it transmits ID information of the beacon transmitter BT contained in the beacon signal to the management server 400.

[0019] The beacon transmitter BT may continue to transmit the beacon signal while the beacon signal is being received by the beacon receiver BR. For example, the beacon transmitter BT may continue to transmit the beacon signal at intervals of 100 milliseconds while the beacon signal is being detected by the beacon receiver BR mounted on the nearby construction machine 100. In the following, for ease of understanding, an example will be described in which the construction-related transported object is construction generated soil.

[0020] The management server 400 is a server that centrally manages the transport vehicles 300 and the like, and is composed of a server computer and the like. The management server 400 includes a control device 410 and a storage device 420. The control device 410 includes, as hardware, a CPU, memories such as ROM and RAM, an input interface, an output interface, a communication interface, and buses connecting these, and the like.

[0021] The control device 410 realizes various functions required for managing each transport vehicle 300 by the CPU executing a program stored in a ROM or the like. The storage device 420 is a hard disk drive or the like, and includes a transport vehicle database (DB) related to the transport vehicles 300. Various transport vehicle information related to the transport vehicles 300 is registered in the transport vehicle DB. The transport vehicle information may include, but is not limited to, for example, the vehicle number, the vehicle number, ID information of the beacon transmitter, the operating status such as the current location of the vehicle, and information related to the loaded load. The registered contents of the transport vehicle DB are updated successively by information transmitted periodically or irregularly from the operator terminal 200 or an external server (not shown), etc.

[0022] Next, a flow of operations (outline) from preparation by the operator of the construction machine 100 to confirmation of performance will be described with reference to FIG. First, the operator operates his / her operator terminal 200 to perform advance preparations for connecting to the CAN-WiFi converter CO via WiFi (step S1). As an example, the operator operates a setting screen (not shown) of the operator terminal 200 and enters an SSID, a password, and the like to establish a WiFi connection with the CAN-WiFi converter CO.

[0023] The operator starts the client application AP installed in the operator terminal 200 (step S2). After that, when the transport vehicle 300 approaches the construction machine 100 operated by the operator (step S3), the operator appropriately operates the operator terminal 200 to select the transport vehicle 300 to load the load (here, construction generated soil) (step S4).

[0024] When the operator is ready to load the construction generated soil, he or she presses the start button B1 of the payload system 110 of the construction machine 100 (step S5) to instruct the start of payload measurement (that is, excavation and loading of construction generated soil, etc.).

[0025] When the construction machine 100 detects that the start button B1 has been pressed, it repeats excavation and loading of construction generated soil until the set loading target is reached (step S6 → step S7). The payload measurement results by the payload system 110 are successively transmitted to the operator terminal 200 and displayed.

[0026] When the operator detects that the loading target has been reached, he or she presses the end button B2 of the payload system 110 (step S8). When the construction machine 100 detects that the end button B2 has been pressed, it notifies the operator terminal 200 that the payload measurement has ended. When the operator terminal 200 receives this notification, it transmits information related to loading (also referred to as payload information) to the management server 400 (step S9). The payload information may include, for example, the loading load of construction generated soil, the elapsed loading time, the loading start time, the loading end time, the number of loadings, etc., but is not limited to these.

[0027] When the management server 400 receives the payload information, it stores it in the transport vehicle DB and updates the transport vehicle information of the transport vehicle 300 registered in the database (step S10). By accessing the transport vehicle DB of the management server 400, a manager who manages the progress of construction work can view and compile the loading results of each transport vehicle 300 in real time, and can more appropriately manage the appropriate operation of the transport vehicles and the results based on the display of the loading target value for each vehicle.

[0028] [Operator terminal configuration] FIG. 3 is a block diagram showing the configuration of the operator terminal 200. As shown in FIG. As shown in FIG. 3, the operator terminal 200 includes, as its physical components, a processor 210, a communication interface 220, a storage device 230, an input device 240, and a display device 250, for example.

[0029] The processor 210 is, for example, a processor such as a CPU, an MPU, etc. The processor 210 executes a program 231 stored in the storage device 230, thereby functioning as a control unit 211 that realizes various functions of the operator terminal 200.

[0030] The control unit 211 realizes, for example, a function of displaying various screens on the display device 250, a function of accepting contents inputted to various screens, a function of exchanging information with the management server 400, etc., in accordance with instructions from an operator who operates the operator terminal 200. The various screens will be described later.

[0031] The communication interface 220 functions as a communication unit that connects to the communication network N and communicates with other devices on the communication network N.

[0032] The storage device 230 is, for example, a computer-readable recording medium such as a disk drive or a semiconductor memory. The storage device 230 functions as a storage unit that stores a program 231 for implementing various functions of the operator terminal 200 and various data used by the program 231. The program 231 includes the above-mentioned client application AP.

[0033] The input device 240 functions as an input unit that accepts input from a user. As the input device 240, for example, a touch panel, a pen tablet, a keyboard, a mouse, a microphone, etc. can be used.

[0034] The display device 250 functions as a display unit that displays (presents) images, screens, etc. to an operator. As the display device 250, for example, an organic EL display, a liquid crystal display, etc. can be used.

[0035] [Screen displayed on operator terminal] With reference to the drawings, various screens displayed on the operator terminal 200 will be described in the following order in (1) to (5).

[0036] (1) Business start screen FIG. 4 shows an example of the business start screen P1. The work start screen P1 is a screen for an operator of the construction machine 100 to instruct the start of work related to construction work (i.e., launching the client application AP). In addition to a work start button B3 for instructing the start of work, the work start screen P1 also displays a loading history button B4 for checking the actual loading record on the transport vehicle 300, a setting button B5 for making various settings, and the like.

[0037] Also, a device ID for identifying the client application AP installed in the operator terminal 200 is displayed at the top of the business start screen P1. Although not shown in the figure, a button for updating information about the transport vehicle 300 scheduled to arrive at the construction site, a button for sending payload information within the past 24 hours to the management server 400, a button for sending all payload information held by the client application AP to the management server 400, and the like may be displayed. When the business start button B3 is pressed by the operator, a selection screen for the transport vehicle 300 is displayed on the display device 250.

[0038] (2) Transport vehicle selection screen 5A and 5B show an example of the transport vehicle selection screen P2. The transport vehicle selection screen P2 is a screen for the operator to select a transport vehicle 300 for loading the construction generated soil excavated by the construction machine 100. The transport vehicle selection screen P2 displays transport vehicle information IF10 related to one or more transport vehicles 300 scheduled to arrive at the site.

[0039] The transport vehicle selection screen P2 also displays an update timer UT indicating the update timing of the transport vehicle information (such as the time until the next update), a task end button B6 for instructing the task end, etc. The transport vehicle information IF10 of one or more transport vehicles 300 scheduled to arrive at the site is transmitted in list form from the management server 400 (described later).

[0040] As already described, the construction machine 100 is equipped with a beacon receiver BR for receiving beacon signals transmitted from each transport vehicle 300. The management server 400 may transmit information on each transport vehicle 300 adjacent to the construction machine 100 to the operator terminal 200 based on information on the beacon signal transmitted from the beacon receiver BR. The information on the beacon signal may include, for example, the reception strength of the beacon signal, the reception time of the beacon signal, and the like, but is not limited thereto. In this embodiment, it is assumed that the operator terminal 200 requests the management server 400 to update information on each transport vehicle 300 adjacent to the construction machine 100, but is not limited thereto. The management server 400 may push updated information on the transport vehicles 300 adjacent to the construction machine 100 to the operator terminal 200.

[0041] The transport vehicle information IF10 includes a vehicle number IF11 indicating the license plate of the transport vehicle 300, a vehicle bib number IF12 indicating the display number (bib number) of the transport vehicle 300 which is required to be attached to large vehicles, and a loading target IF13 indicating the target volume of soil to be loaded onto the transport vehicle 300.

[0042] In the example shown in Fig. 5A, the transport vehicle information IF10 of the transport vehicle 300 close to the construction machine 100 is highlighted. Specifically, the transport vehicle information IF10 of the transport vehicle 300 that was able to receive a beacon signal by the beacon receiver BR of the construction machine 100 is displayed in a first color (e.g., green) (first and second from the top in Fig. 5A).

[0043] On the other hand, the transport vehicle information IF10 of the transport vehicle 300 whose beacon signal could not be received by the beacon receiver BR of the construction machine 100 is displayed in a second color (for example, gray) (third to fifth from the top in FIG. 5A).

[0044] In this embodiment, the transport vehicle 300 approaching the construction machine 100 is highlighted by changing the display color of the transport vehicle information IF10, but the highlighting method is not limited to this as long as the operator can identify the approaching transport vehicle 300. For example, the approaching transport vehicle 300 may be highlighted by making the transport vehicle information IF10 relating to the approaching transport vehicle 300 blink on the operator terminal 200.

[0045] The size of the transport vehicle information IF10 of the transport vehicle 300 may be changed depending on the proximity state of each transport vehicle 300. For example, the transport vehicle 300 that could not receive the beacon signal and the transport vehicle 300 that could only receive the beacon signal with a reception strength lower than a preset threshold may be displayed in a normal size or a size reduced from the normal size (second to fourth from the top in FIG. 5A), and the transport vehicle 300 that could receive the beacon signal with a reception strength higher than a preset threshold may be displayed in a size enlarged from the normal size (first from the top in FIG. 5A). However, the manner in which the transport vehicle information IF10 is displayed can be arbitrarily set or changed depending on the UI design, etc. For example, as illustrated in FIG. 5B, the transport vehicle information IF10 of each transport vehicle 300 may be displayed in the same size (normal size) without being emphasized. According to such a screen configuration (layout), the operator can efficiently grasp the overall image of each transport vehicle 300 that is scheduled to approach the construction machine 100 later.

[0046] The operator visually checks the nearby transport vehicles 300, selects the transport vehicle 300 to be loaded, and presses the vehicle number IF11 corresponding to the selected transport vehicle 300. When the operator presses any one of the vehicle number IF11, a loading screen is displayed on the display device 250.

[0047] (3) Loading screen FIG. 6 shows an example of the loading screen P3. The loading screen P3 is a screen for displaying information related to the loading of construction generated soil onto the selected transport vehicle 300. The loading screen P3 displays a loading status IF21 indicating the loading state (status), a vehicle number IF22 of the transport vehicle 300 performing the loading, a tip load IF23 indicating the amount of construction generated soil (soil volume) scooped up by the bucket of the construction machine 100, a loading load IF24 indicating the total amount of soil loaded onto the transport vehicle 300, a loading target IF25 indicating the target amount of soil to be loaded onto one transport vehicle 300 during loading, a loading count IF26 indicating the total number of times one transport vehicle 300 has been loaded, a back button B7 for returning to the transport vehicle selection screen P2, and the like.

[0048] The operator presses the start button B1 (see FIG. 1) of the payload system 110 of the construction machine 100. When this operation is performed, the loading status IF21 of the transport vehicle 300 displayed on the loading screen P3 switches from "Waiting to start loading" to "Loading". The loading target IF25 may be set in advance for each transport vehicle 300 based on the vehicle width, overall length, vehicle weight, maximum load capacity, etc., or may be set appropriately by an administrator or the like who manages the transport vehicle 300.

[0049] (4) Loading completion screen FIG. 7 shows an example of the loading completion screen P4. The loading completion screen P4 is a screen for displaying information indicating the completion of loading of construction generated soil. The loading completion screen P4 displays a loading status IF31 indicating the loading state (status), a vehicle number IF32 of the transport vehicle 300 performing the loading, a loading load IF33 indicating the total amount of soil loaded onto the transport vehicle 300, a loading target IF34 indicating the target amount of soil to be loaded onto one transport vehicle 300, and a loading count IF35 indicating the total number of times one transport vehicle 300 has been loaded.

[0050] In addition, the middle and lower sections of the loading completion screen P4 display the work time T1, which indicates the time elapsed since the start button B1 was pressed, the loading start time T2, which indicates the time when the start button B1 was pressed, the loading end time T3, which indicates the time when the end button B2 was pressed, and a close button B8 for returning to the transport vehicle selection screen P2.

[0051] When the operator judges that the loading of construction generated soil by the construction machine 100 should be ended, he / she presses the end button B2 (see FIG. 1) of the payload system 110. When this operation is performed, the loading status IF31 of the transport vehicle 300 displayed on the loading completion screen P4 switches from "loading" to "completed." When the operator then presses the close button B8, the transport vehicle selection screen P2 is displayed on the display device 250.

[0052] The close button B8 may be hidden by settings. In this case, the screen may automatically return to the transport vehicle selection screen P2 after a predetermined time has elapsed since the loading status IF31 was switched to "Completed". In addition, when the load of construction generated soil by the construction machine 100 exceeds the loading target, the load may be displayed in red or flashing to alert the operator of the risk of overloading.

[0053] (5) Setting screen FIG. 8 shows an example of the setting screen P5. The setting screen P5 is a screen for the operator to make various settings related to the work. The setting screen P5 displays a first setting ST1 for setting whether to display or hide the close button B8 on the loading completion screen P4 (see FIG. 7), a second setting ST2 for setting the time for automatically returning from the loading completion screen P4 to the transport vehicle selection screen P2, and a third setting ST3 for setting whether to display or hide the display number (bib number) of the transport vehicle 300 on the transport vehicle selection screen P2. Furthermore, the setting screen P5 displays a fourth setting ST4 for setting a loading target for the transport vehicle 300, a fifth setting ST5 for setting a threshold value for the radio wave strength of the beacon signal for determining whether the transport vehicle 300 is approaching, and a sixth setting ST6 for setting an interval (refresh rate) for reading data from the CAN-WiFi converter CO.

[0054] As an example, the loading target is set by specifying a numerical value (for example, in units of 0.1 (t)) to be subtracted from the maximum loading capacity of the transport vehicle 300. Meanwhile, the threshold value of radio wave strength is set to classify the size of the display of the vehicle number on the transport vehicle selection screen P2. Of course, the setting of the loading target and the threshold value of radio wave strength is not limited to these methods, and any method can be adopted. After making each of the above settings, the operator presses the setting button B9 to save the settings in the operator terminal 200.

[0055] In the above description, no particular reference was made to error display, but error display may be performed in various ways. For example, if a communication failure occurs while the transport vehicle selection screen P2 is being displayed and the nearby transport vehicle information IF10 cannot be acquired at the correct timing, the update timer UT may be displayed in red to notify the operator that an error has occurred. In addition, if the WiFi connection between the CAN-WiFi converter CO and the operator terminal 200 is disconnected, a message indicating that a communication error has occurred may be displayed as a pop-up on the operator terminal 200.

[0056] [Operation of integrated fleet management system] Next, the operation of the integrated fleet management system 1 in the embodiment will be described with reference to FIG. The operator operates the operator terminal 200 to start the client application AP (step S101). When the client application AP is started, the operator terminal (request unit) 200 requests the management server 400 for a list of transport vehicle information (transport vehicle list) regarding one or more transport vehicles 300 scheduled to arrive at the site, including the device ID of the client application AP (step S102).

[0057] When the management server 400 receives the request, it refers to the transport vehicle DB, identifies one or more transport vehicles 300 scheduled to arrive at the site, and generates and extracts a transport vehicle list of the identified transport vehicles 300. The management server 400 transmits the extracted transport vehicle list to the operator terminal (step S103). When the operator terminal (second receiving unit) 200 receives the transport vehicle list, it stores it in the storage device 230 and displays the received transport vehicle list on the display device. Thereafter, the operator terminal 200 requests transport vehicle information (nearby transport vehicle information) of the transport vehicles 300 that are close to the construction machine 100 at a predetermined timing (for example, every 5 (s)). The management server 400 may push the transport vehicle information of the transport vehicles 300 that are close to the construction machine 100, not only when there is a request from the operator terminal 200.

[0058] Meanwhile, the operator presses the start button B1 to start loading work using the payload system 110 (step S104). When the payload system 110 detects the pressing of the start button B1, it sends a loading work start instruction to the operator terminal 200 via the CAN-WiFi converter CO. The beacon transmitters BT mounted on each transport vehicle 300 scheduled to arrive at the site send out a beacon signal including ID information (step S105). When the beacon receiver BR mounted on the construction machine 100 receives a beacon signal including ID information from the beacon transmitter BT of a nearby transport vehicle 300, it transmits this to the management server 400 (step S106).

[0059] When the management server 400 receives a beacon signal from the beacon receiver BR mounted on the construction machine 100, it refers to the transport vehicle DB stored in the storage device 420, links the vehicle number of the transport vehicle 300 with information about the beacon signal (step S107), and performs proximity determination of the transport vehicle 300 (step S108). Specifically, the management server (identification unit) 400 identifies the transport vehicle 300 that is in proximity to the construction machine 100 based on the reception conditions of the beacon signal, such as the reception strength and reception time of the beacon signal. Then, the management server (transmission unit) 400 extracts transport vehicle information of the identified transport vehicle 300 (i.e., adjacent transport vehicle information) from the transport vehicle DB, and transmits it to the operator terminal 200 (step S109).

[0060] When the operator terminal (first receiving unit, display control unit) 200 receives the nearby transport vehicle information, it displays a transport vehicle selection screen P2 as shown in FIG. 5 and prompts the operator to select the transport vehicle 300 to be the loading destination. The operator visually checks the nearby transport vehicles 300 while checking the transport vehicle selection screen P2, and selects the transport vehicle 300 to actually load (step S110). Specifically, the operator uses the operator terminal 200 to press the vehicle number IF11 corresponding to the selected transport vehicle 300. When the operator terminal (reception unit) 200 accepts the selection of the transport vehicle 300 to actually load, the construction machine 100 starts excavation work. As the construction machine 100 starts work, the payload system 110 transmits payload information including the loading load of construction generated soil, loading elapsed time, loading start time, loading end time, loading count, etc. to the operator terminal 200 via the CAN-WiFi converter CO (step S111).

[0061] When the operator terminal (third receiving unit) 200 receives the payload information, it displays a loading screen P3 as shown in Fig. 6. After that, when the operator determines that the loading load of construction generated soil displayed on the loading screen P3 has reached the loading target and loading should be ended, he presses the end button B2 of the payload system 110 (step S112). When this operation is performed, the payload system 110 notifies the operator terminal 200 of the completion of loading.

[0062] When the operator terminal 200 receives the notification of the completion of loading, it displays a loading completion screen P4 as shown in FIG. 7. After that, when the operator presses the close button B8 displayed on the loading completion screen P4 (step S113), the operator terminal 200 displays the transport vehicle selection screen P2. Furthermore, the operator terminal 200 transmits payload information to the management server 400 together with the vehicle number of the transport vehicle 300 that has completed loading (step S114). Specifically, the operator terminal 200 transmits the loading load of the construction generated soil, the loading elapsed time, the loading start time, the loading end time, the number of loadings, etc., to the management server 400, linking them to the vehicle number of the transport vehicle 300. When the management server 400 receives the payload information from the operator terminal 200, it links the received payload information to the vehicle number of the transport vehicle 300 that has completed loading, stores the received payload information in the transport vehicle DB (step S115), and ends the process.

[0063] As described above, according to the integrated fleet management system of this embodiment, the nearby transport vehicle information of transport vehicles near the construction machine is narrowed down and displayed from a transport vehicle list that lists transport vehicles scheduled to arrive at the site based on the communication status between the beacon transmitter mounted on each transport vehicle and the beacon receiver mounted on the construction machine. The operator who operates the construction machine can easily select an appropriate transport vehicle taking into consideration the loading weight, etc. by checking the nearby transport vehicle information displayed on the operator terminal.

[0064] In addition, while the construction machine is loading the transport vehicle, the vehicle number of the transport vehicle, as well as information such as the loading weight, loading target, and number of loadings are displayed in real time on the operator terminal. By checking the operator terminal, the operator can carry out appropriate loading work according to the loading target, etc.

[0065] [Variations] The present invention is not limited to the above-mentioned embodiment, and can be embodied in various other forms without departing from the scope of the present invention. Therefore, the above-mentioned embodiment is merely an example in every respect, and should not be interpreted as being restrictive. For example, the above-mentioned processing steps can be arbitrarily changed in order or executed in parallel as long as there is no contradiction in the processing contents. As an example, the processing of step S104 may be executed before step S105, or after step S110.

[0066] In addition, the programs in the above-described embodiments can be installed or loaded into a computer through various recording media (computer-readable recording media) such as optical disks such as CDs and DVDs, magnetic disks, and semiconductor memories, or by downloading them from a server device (medium) via a communication network, etc. [Explanation of symbols]
