[0004] Patent Document 1: Japanese Patent Application Publication No. 2022-140355

[0005] Information used for road construction or information detected during road construction is no longer used when the construction is completed. Therefore, even if the construction machinery workers sometimes temporarily save the construction information during road construction in order to confirm the construction content, it will be deleted in the long run. In other words, the construction information during road construction is usually only used after the construction machinery has been used once, and is not used for other opportunities. Summary of the invention

[0006] The present invention provides a technology capable of improving convenience by appropriately utilizing construction information when a construction machine is constructing a road.

[0007] According to one embodiment of the present invention, there is provided a construction information management system, which includes: a construction machine for performing road construction; a server device for acquiring construction information when the construction machine performs the road construction and storing the information in a database; and a client device for being connected to the server device for information communication. In the construction information management system, the server device sends provision information including part or all of the construction information during the road construction stored in the database to the client device based on access by the client device.

DETAILED DESCRIPTION

[0019] Hereinafter, the mode for implementing the present invention will be described with reference to the drawings. In each of the drawings, the same components are denoted by the same reference numerals, and duplicate description may be omitted.

[0020] Figure 1 1 is a diagram showing the overall structure of the construction information management system 1 according to the embodiment. Figure 1 As shown, the construction information management system 1 involved in the embodiment includes: a work site CP where a construction machine 10 actually constructs a road, a management location AP having a server device 100, and a use location UP having a client device 200. Various structures of the work site CP, the server device 100 of the management location AP, and the client device 200 of the use location UP are connected to each other via a network 300 such as the Internet so as to be able to communicate information.

[0021] The construction information management system 1 is preferably constructed by a group that manages roads in a wide range, such as a national unit, a prefectural unit, or a municipal unit. In addition, the construction information management system 1 can be constructed in an association composed of multiple companies performing construction or in a single company. Figure 1 In FIG. 1 , one work site CP is illustrated, but there are multiple (many) work sites CP managed by the construction information management system 1. Figure 1 Although one management location AP is illustrated, there may be multiple management location APs and server devices 100. When multiple server devices 100 are provided, the server devices 100 may be connected to each other in a peer-to-peer manner so as to be able to communicate information, for example.

[0022] At the work site CP where the road is being constructed, a road construction company prepares a plurality of construction machines 10. For example, as the construction machines 10, a road cutter 20 for cutting asphalt on the road surface, an asphalt roller 30 for applying new asphalt, and a dump truck 40 can be cited. In addition, the construction machines 10 used at the work site CP are not limited thereto, and various machines can be used depending on the road construction content and / or construction scope. For example, as other construction machines 10, an asphalt spreader, a sprayer, a suction truck, a snowplow, etc. can be cited.

[0023] Furthermore, a terminal 50 for managing road construction can be prepared at the work site CP. The terminal 50 for the work site is configured to communicate information with each construction machine 10 such as a road cutter 20 or an asphalt roller 30, and to provide information required by each construction machine 10 or obtain information of each construction machine 10. The terminal 50 for the work site is not particularly limited, but for example, a laptop computer or a tablet computer that can be easily carried is preferably used. Furthermore, the terminal 50 for the work site can be used as a client device 200 that obtains information provided by the server device 100.

[0024] The road cutting machine 20 used in the work site CP is a construction machine 10 that cuts (crushes, cuts, etc.) asphalt constituting the road surface while traveling on the road. For example, the road cutting machine 20 includes: a vehicle body 21 that allows the road cutting machine 20 to travel; a cutting mechanism 22 that cuts the road surface R; and a conveyor 23 that conveys cuttings generated by the cutting mechanism 22.

[0025] The vehicle body 21 includes a plurality of wheels 24 (or tracks), a driver's seat 25, etc. Furthermore, an engine (not shown), a controller 26 for controlling the operation of the road cutting machine 20, etc. are provided inside the vehicle body 21.

[0026] The cutting mechanism 22 has a tool disc 221 extending in the vehicle width direction of the vehicle body 21 and rotatable between the front and rear wheels 24 at the lower part of the vehicle body 21, and a plurality of cutter heads 222 protruding from the outer peripheral surface of the tool disc 221. In addition, the tool disc 221 of the cutting mechanism 22 can be moved in the vertical direction relative to the vehicle body 21 by other hydraulic cylinders not shown, and the cutting depth of the road surface by the cutter heads 222 can be adjusted. The road surface cutting machine 20 discharges the cutting chips scraped by the cutting mechanism 22 to the conveyor 23.

[0027] The conveyor 23 delivers the chips scraped by the cutting mechanism 22 to another location (eg, a cargo box of a dump truck 40 traveling together with the road cutter 20 in front of the road cutter 20). In order to efficiently transport the chips, a plurality of conveyors 23 may be provided.

[0028] Furthermore, the road cutting machine 20 is provided with various detection sensors 27, which detect the operation state of the road cutting, etc. under the control of the controller 26, and send the detection information to the controller 26. The detection sensors 27 of the road cutting machine 20 are not particularly limited, but examples thereof include GNSS positioning devices, distance detection sensors, posture detection sensors, speed sensors, encoders, cameras, other optical sensors, other magnetic sensors, and the like.

[0029] Figure 2 The diagram shows the hardware configuration of the controllers 26 and 36 of the construction machine 10 , the work site terminal 50 , the server device 100 , and the client device 200 .

[0030] like Figure 2 As shown, the function of the controller 26 of the road cutting machine 20 as the construction machine 10 is realized by any hardware, software or a combination thereof. For example, as the controller 26, a computer having a processor 11, a memory 12, an input unit 13, an output unit 14 and a communication unit 15 can be applied. The processor 11 is one or a combination of a plurality of circuits such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), and a circuit composed of a plurality of discrete semiconductors, and executes a program stored in the memory 12. The memory 12 includes a main storage device composed of a semiconductor memory and an auxiliary storage device composed of a magnetic disk or a semiconductor memory (flash memory).

[0031] The input unit 13 of the construction machine 10 may adopt an appropriate structure according to the operation mode of the construction machine 10, for example, including buttons, handles, joysticks, pedals, touch panels, etc. In addition, the output unit 14 of the construction machine 10 may include a display or a speaker, and include various structures controlled by the controller 26 in the construction machine 10. The communication unit 15 applies a communication module with an appropriate communication standard capable of directly communicating with the work site terminal 50 (or other construction machines 10) or the network 300.

[0032] The target construction information related to the road to be constructed is input manually by the staff to the controller 26 of the road cutting machine 20, or is input from the terminal 50 (or the client device 200) at the work site. As the target construction information, for example, the shape of the road (length, width, slope, etc.), the state of the road (type, density, thickness, presence or absence of cracks or damage of the paving material constituting the road), and the construction range of the scheduled cutting (construction length, construction width, etc.) can be cited. The controller 26 calculates the cutting depth, target construction track, target construction speed, etc. of the road cutting machine 20 based on the input target construction information, and performs operation support control of the road cutting machine 20 based on the calculation result. The operation support control based on the controller 26, for example, can include adjustment control for automatically adjusting the height of the cutting mechanism 22 according to the cutting depth, and autonomous operation control for automatically moving the road cutting machine 20 according to the target construction track and target construction speed during cutting and cutting the road surface. Alternatively, the operation support control can be a guidance function for notifying the staff of the road cutting machine 20 of the target height and / or target construction track of the cutting mechanism 22.

[0033] Furthermore, the controller 26 has the following functions: when cutting the road surface, selectively collects Figure 1 The detection information detected by the various detection sensors 27 shown in the figure is stored in the memory. As the detection information detected by the road cutting machine 20 when cutting the road surface, for example, the construction length, construction width, construction thickness (cutting depth) and the like as information of the construction position of the road actually constructed can be cited. In addition, the detection information detected by the road cutting machine 20 also includes the construction track and construction speed on which the road cutting machine 20 moves as information of the construction content of the road. Hereinafter, the detection information detected by the construction machine 10 when constructing the road will also be referred to as actual construction information.

[0034] Back to Figure 1The asphalt roller 30 spits out paving materials such as asphalt mixture onto the lower surface of the road (e.g., the ground), and levels the spewed paving materials, thereby spreading the paving materials on the road. For example, the asphalt roller 30 includes: a tractor 31 for driving the asphalt roller 30; a hopper 32 provided in front of the tractor 31; and a leveler 33 provided at the rear of the tractor 31.

[0035] The tractor 31 uses a hydraulic motor for traveling (not shown) to rotate a plurality of wheels 34, thereby moving the asphalt roller 30. The asphalt roller 30 may use crawler tracks instead of the wheels 34. In addition, a driver's seat 35 for riding the asphalt roller 30 is provided on the upper part of the tractor 31. An engine (not shown) and a controller 36 for controlling the operation of the asphalt roller 30 are provided inside the tractor 31.

[0036] The hopper 32 is a mechanism for receiving paving materials, and is configured to be openable and closable in the vehicle width direction by a hopper cylinder (not shown). For example, the hopper 32 receives paving materials from a dump truck (not shown) in an open state. The paving materials supplied to the hopper 32 are delivered to the rear side of the tractor 31.

[0037] Furthermore, the paving material moved to the rear side of the tractor 31 is spread in the vehicle width direction of the leveler 33 by a screw not shown. The leveler 33 of the asphalt roller 30 is a mechanism for evenly spreading the paving material, and in the embodiment, a floating leveler towed by the tractor 31 is used. For example, the leveler 33 includes: a front leveler 331 that roughly levels the paving material first; and a rear leveler 332 that adjusts the leveling of the paving material behind the front leveler 331.

[0038] Furthermore, the asphalt roller 30 is provided with a detection sensor 37, which detects the operation state when the paving material is evenly spread and / or the state of the evenly spread paving material, and sends the detected detection information to the controller 36. The detection sensor 37 is also similar to the detection sensor 27 of the road cutting machine 20, and for example, a GNSS positioning device, a distance detection sensor, a posture detection sensor, a speed sensor, an encoder, a camera, other optical sensors, other magnetic sensors, etc. can be applied.

[0039] The controller 36 of the asphalt roller 30 is similar to the controller 26 of the road cutting machine 20, and its functions are realized by arbitrary hardware, software, or a combination thereof. The controller 36 can be implemented by a computer having a processor 11, a memory 12, an input unit 13, an output unit 14, and a communication unit 15 (see Figure 2 ).

[0040] The controller 36 of the asphalt roller 30 is similar to the controller 26. The target construction information related to the road to be constructed is input manually by the worker, or input from the work site terminal 50 (or the client device 200). Examples of the target construction information include the shape of the road (length, width, slope, etc.), the construction range of the paving material to be supplied (construction length, construction width, construction thickness, etc.), the state of the road (the state of the exposed ground, the residual state of asphalt, etc.), and the information of the paving material (the type of paving material, etc.).

[0041] The controller 36 calculates the supply width and / or supply height of the paving material of the asphalt roller 30, the target construction track, the target construction speed, etc. according to the target construction information, and performs operation support control of the asphalt roller 30 according to the calculation results. The operation support control based on the controller 36, for example, can include adjustment control of automatically adjusting the screed machine 33 according to the supply width and / or supply height, and autonomous operation control of automatically moving the road cutter 20 and paving the paving material according to the target construction track and the target construction speed. Alternatively, the operation support control can be a guidance function that notifies the staff of the asphalt roller 30 of the adjustment of the screed machine 33 and / or the target construction track.

[0042] In addition, the controller 36 has the following function: when supplying paving materials, it selectively collects detection information detected by various detection sensors 37 of the asphalt roller 30 and stores it in the memory. As the detection information when supplying paving materials, for example, the construction length, construction width, construction thickness (construction height) and the like at the construction position of the actual construction can be cited. In addition, the detection information of the asphalt roller 30 also includes the construction track and construction speed of the asphalt roller 30 as information on the construction content of the road. Alternatively, in the case where the detection sensor 37 takes a picture of the paving materials actually supplied, the controller 36 can perform image processing on the video information, calculate the information of the constructed paving materials (density of the paving materials, height difference with other unconstructed road surfaces, unevenness, etc.), and store the information.

[0043] In addition, if Figure 2 As shown, the work site terminal 50 of the work site CP can be applied to a computer having a processor 51, a memory 52, an input unit 53, an output unit 54, and a communication unit 55. The input unit 53 is composed of a keyboard, a mouse, a touch panel, etc. The output unit 54 is composed of a display (including a touch panel display) and a speaker, etc.

[0044] The work site terminal 50 can exchange information with the controller 26, 36, etc. via wired communication, wireless communication, or a storage medium such as a USB memory. For example, the work site terminal 50 sends target construction information to each construction machine 10 before construction. In addition, for example, the work site terminal 50 obtains actual construction information (construction information during road construction) detected by each construction machine 10 after construction.

[0045] Then, the work site terminal 50 of the work site CP is connected to the network 300 in a wired or wireless communication manner, and can access the server device 100 of the management location AP. The construction information management system 1 sends the actual construction information stored by the work site terminal 50 during the road construction from the work site terminal 50 to the server device 100. Thus, the construction information management system 1 can store the construction information (actual construction information) during various road constructions in the server device 100. In addition, the construction information management system 1 can also be configured as follows: the construction information is sent directly (not via the work site terminal 50) from the controller 26 of the road cutter 20, the controller 36 of the asphalt roller 30, etc. to the server device 100.

[0046] The server device 100 of the management location AP is a computer that collectively stores construction information of a plurality of work sites CP. The server device 100 manages a plurality of construction information as big data (aggregate) in a database, and can provide information to the client devices 200 of a plurality of usage locations UP.

[0047] Specifically, the server device 100 includes a processing unit 101, a storage device 102, an input device 103, an output device 104, and a communication device 105. In this case, the processing unit 101 can be composed of a plurality of server CPUs. The storage device 102 is a large-capacity storage device, for example, a storage rack or a recording and reproducing mechanism formed by collecting a plurality of cassette recording media. The input device 103 is a well-known keyboard, mouse, etc. The output device 104 is a well-known display, speaker, etc. The communication device 105 is a communication device capable of transmitting data to the network 300 in a large capacity and at a high speed.

[0048] On the other hand, the client device 200 connected to the server device 100 via the network 300 can be a general-purpose computer having a processor 201, a memory 202, an input unit 203, an output unit 204, a communication unit 205, etc. The client device 200 can be a desktop computer, a laptop computer, a tablet terminal including a smartphone, a wearable computer, etc.

[0049] The server device 100 stores the construction information (actual construction information) acquired from the work site CP in a database. Therefore, the processing unit 101 of the server device 100 executes a program (not shown) stored in the storage device 102 to construct a database such as Figure 3 The functional blocks shown are used to database the construction information. Figure 3 This is a block diagram showing the functional blocks of each device of the construction information management system 1 .

[0050] Specifically, a construction information acquisition unit 111, a database processing unit 112, a distribution information generation unit 113, a distribution unit 114, a request information acquisition unit 115, a detailed information generation unit 116, and an information transmission unit 117 are formed inside the server device 100. Furthermore, an information acquisition unit 211, a request information generation and output unit 212, a construction plan generation unit 213, and a pre-construction information output unit 214 are formed inside the client device 200. The information acquisition unit 211, the request information generation and output unit 212, the construction plan generation unit 213, and the pre-construction information output unit 214 may be formed by an application installed in the client device 200, or may be formed by the client device 200 opening information (homepage, etc.) on the network 300.

[0051] The construction information acquisition unit 111 of the server device 100 acquires the actual construction information of the work site CP by communicating information with the work site terminal 50. For example, if the staff of the work site terminal 50 performs construction on the road, the actual construction information is sent from the construction machine 10 (pavement cutter 20, asphalt roller 30, etc.) used to the work site terminal 50. Then, the staff of the work site terminal 50 appropriately organizes the acquired actual construction information and sends it to the server device 100. For this purpose, the work site terminal 50 may have an application that extracts appropriate information from a plurality of actual construction information of the construction machine 10 and sends the extracted information to the server device 100. In addition, the work site terminal 50 can access the server device 100 from the work site CP, but can also access the server device 100 from a place different from the work site CP, such as an office building of a construction company.

[0052] The construction information (actual construction information) sent to the server device 100 includes "construction location", "construction date", "construction content", "construction machinery", "paving materials", "construction length", "construction width", "construction thickness", "construction track", "construction speed", "state of the road after construction", etc. However, the actual construction information may be changed according to the construction content of the road or the construction machinery 10 used. In addition, the actual construction information may include construction drawings used for construction, or may also include target construction information used for construction.

[0053] The "construction location" included in the construction information can be location information including longitude and latitude automatically acquired by the GNSS positioning device of the construction machine 10, or can be information measured by the staff. For example, the controller 26, 36 of the construction machine 10 can continuously detect the log of the moving location information during the actual construction, and store it as a parameter of the construction location. Alternatively, the "construction location" can also be the address of the work site CP, etc.

[0054] The "construction date" is the year, month, and day when the construction of the work site CP was carried out and the construction was completed. The "construction date" may include the time when the work was completed, etc. In addition, the work site terminal 50 may automatically extract the date when the actual construction information is received and set it as the "construction date". In addition, in the case where the road construction spans multiple days, the actual construction information may be sent to the server device 100 even during the construction. In this case, the server device 100 only needs to update the past actual construction information at any time as new actual construction information is received.

[0055] "Construction content" is information indicating the type of construction performed on the road. For example, if asphalt is paved, asphalt paving is recorded, and if concrete is paved, concrete paving is recorded. In addition, "construction content" such as drainage paving, permeable paving, water-retaining paving, and block paving is also recorded. The controller 26, 36 of the construction machine 10 can automatically provide the construction content performed during actual construction to the work site terminal 50 or the server device 100.

[0056] "Construction machinery" is information indicating the model of the construction machinery 10 used in road construction. For example, "construction machinery" may include an identification number marked on the construction machinery 10, or may include the name, model, etc. of the construction machinery 10. When the controller 26, 36 of the construction machinery 10 sends other information to the work site terminal 50 or the server device 100, it may automatically attach the model information and send it.

[0057] “Paving material” is information indicating the type, mixture content, particle size, etc. of the paving material used for the road surface during road construction. For example, “paving material” may record an identification number marked on the paving material, or may record the name of the paving material, etc. When the controller 36 of the asphalt roller 30 obtains the paving material information as the target construction information, it may automatically send the information.

[0058] "Construction length" is information indicating the length of the actual construction along the direction in which the road extends. "Construction width" is information indicating the width of the actual construction in the width direction of the road. "Construction thickness" is information indicating the thickness of the actual construction in the thickness direction of the road (cutting depth, height of paving material). The controllers 26 and 36 of the construction machine 10 can detect the construction length, construction width and construction thickness performed during the actual construction by the detection sensors 27 and 37 and store the parameters.

[0059] The "construction track" is a track along which the construction machine 10 moves during construction, and can be generated, for example, by recording the path along which the construction machine 10 moves when looking down at the construction area. The construction track may include the number of times the construction machine 10 reciprocates the same location multiple times.

[0060] The "construction speed" is the speed at which the construction machine 10 moves during construction. For example, the controller 26, 36 of the construction machine 10 detects and stores the construction speed during actual construction using the detection sensors 27, 37. The construction speed of the construction machine 10 can be used as a parameter that affects the density of the paving material laid on the road during construction.

[0061] The “road status after construction” is information indicating the status of the road after construction by the construction machine 10. The “road status after construction” may be, for example, video information captured by a camera installed on the construction machine 10, or may be information inferring the status of the road (density of paving materials, unevenness, height difference from other road surfaces, slope, etc.) by performing image processing on the video information. Furthermore, the road status after construction may be information measured or captured by a worker at the work site CP.

[0062] The database processing unit 112 selects the construction information (actual construction information) obtained by the construction information acquisition unit 111, or calculates it into information that can be stored in the database DB, and registers it in the database DB. For example, the database processing unit 112 marks the construction information with an identification number, and after rearranging the information attached to the construction information in a manner consistent with the pre-set items, registers the construction information in the database DB. In the case where different actual construction information is stored at the same construction location, the database processing unit 112 can retain the actual construction information with a newer date and delete the data with an older date.

[0063] Figure 4 1 is a diagram showing a database DB managed by the server device 100. The database processing unit 112 generates the following information based on the construction information (actual construction information) acquired by the construction information acquisition unit 111: Figure 4The database DB shown. For example, the database DB has items such as "identification number", "construction location", "construction date", "construction content", "construction machinery", "paving material", "construction length", "construction width", "construction thickness", "construction track", "construction speed", and "state of the road after construction". The database processing unit 112 organizes the construction information obtained from the work site CP in a manner corresponding to each item of the database DB. In the case where there is no information corresponding to an item in the database DB, the database processing unit 112 can set the item to blank and register it. Alternatively, in the case where there is no item required for registration in the database DB, the database processing unit 112 can request the information from the work site terminal 50.

[0064] The "construction location" of the database DB includes the range of coordinates (longitude, latitude) where the road was constructed, and can be used to match the construction information with the map information of the distribution information 500 described later. In addition, the "construction location" becomes an indicator when the user of the client device 200 searches for construction information from the distribution information 500 (database DB) of the server device 100. In addition, the "construction location" indicates the construction range where the road was constructed last time, and thus also becomes information that can be used for construction planning when construction including the construction range is performed.

[0065] The "construction date" in the database DB is information on the date when the road was constructed, and the user of the client device 200 can use this information to identify the period of time since the last construction of the road. For example, in the case of new construction, the user can understand the state of the road to some extent based on the elapsed time.

[0066] The "construction content" of the database DB is information such as the type of construction performed on the road, and the user of the client device 200 can use this information to identify the paving status of the road. For example, when a new road is being constructed, the user can use the "construction content" to make a construction plan. In addition, when the construction machine 10 is an asphalt roller 30, the "construction content" also becomes a requirement for setting the paving content.

[0067] The "construction machine" of the database DB is information such as the model of the construction machine 10 used in the road construction, and the user of the client device 200 can use it to select the construction machine 10 when performing new construction. As an example, when the construction machine 10 is an asphalt roller 30, by knowing its model, the width of the tractor 31 and the width of the leveler 33 can be known, so that the construction track can be calculated based on the mechanical error with the asphalt roller 30 used. Alternatively, when there is a construction machine 10 of the same type as the previous construction machine 10, the information of the previous construction machine 10 can be used, so that the construction plan can be easily prepared.

[0068] The “paving material” in the database DB is information such as the types of paving materials on the road surface, and can be used by the user of the client device 200 to select a paving material when performing new construction and to select a construction machine 10 corresponding to the paving material.

[0069] The "construction length" and "construction width" of the database DB are information indicating the construction range of the road, and the user of the client device 200 can identify the construction range of the previous road based on this information. For example, when a new road is being constructed, the user can compare the construction range of the previous road with the construction range of the new road to make a construction plan.

[0070] The "construction thickness" of the database DB is information indicating the construction range in the thickness direction of the road, and the user of the client device 200 can use this information to set the construction thickness of the construction machine 10, the amount of paving material used, etc. For example, when the construction machine 10 is an asphalt roller 30, the "construction thickness" can be used as information for adjusting the supply amount of paving material to the road surface.

[0071] The "construction track" of the database DB is the track used by the construction machine 10 when it last performed construction. The user of the client device 200 can identify what track was used in the last road construction or the construction status of the road based on this information. In addition, when the same construction machine 10 is used in new road construction, the construction track can be used as it is. When the construction machine 10 is an asphalt roller 30, the "construction track" can be used as information for setting the movement content of the asphalt roller 30.

[0072] The "construction speed" of the database DB is the speed at which the construction machine 10 moved during the last road construction. For example, when the construction machine 10 is an asphalt roller 30, the slower the "construction speed", the higher the density of the paving material of the road. The user of the client device 200 can infer the construction status to some extent based on the "construction speed". In addition, when the same construction machine 10 is used in new road construction, the "construction speed" can be used.

[0073] The "road state after construction" of the database DB is information indicating the state of the road other than the construction thickness, construction track, and construction speed, and may include various information. For example, when the construction machine 10 is an asphalt roller 30, by using the "road state after construction", it is set to correspond to the paving state of the surrounding roads, thereby suppressing the height difference with the surrounding roads.

[0074] Back to Figure 3 , the distribution information generation unit 113 generates distribution information 500 as provided information to be provided to the client device 200. That is, the server device 100 not only stores the construction information of the work site CP, but also transmits the provided information to the client device 200 that has accessed the server device 100. For example, the server device 100 distributes the distribution information 500 associated with the map information 510 for a plurality of construction information in the database DB to the network 300. Thus, the user of the client device 200 can access the distribution information 500 and easily retrieve the required information.

[0075] Figure 5 2 is a diagram illustrating distribution information 500 generated by the server device 100. The distribution information 500 has a data structure in which a plurality of data layers such as map information 510, position information 520, and simple construction information 530 are superimposed.

[0076] The map information 510 is a road map that records roads registered with government agencies, etc. In addition to the road map, the map information 510 may also include information on facilities such as stations, lines, houses or buildings, landmarks, and natural environments such as mountains or lakes. The map information 510 may be mapped using a network such as Google Maps (registered trademark).

[0077] The position information 520 is information indicating the position of a road by longitude and latitude. The position information 520 can be formed by, for example, setting a plurality of nodes having longitude and latitude on the road in the map information 510 and connecting the nodes with links.

[0078] The simple construction information 530 reads the construction information registered in the database DB, and the "construction location" of the construction information is associated with the location information 520 of the distribution information 500, thereby being superimposed on the map information 510 of the distribution information 500. The simple construction information 530 is displayed on the client device 200 (display) by the user of the client device 200 operating the distribution information 500.

[0079] The simple construction information 530 may include items of the construction information in the database DB, which are selected so as to provide enough information to easily identify the construction status of the road in order to reduce the processing load of the server device 100. Figure 5 As shown, in the simple construction information 530, the construction date, construction content, construction width, construction thickness, etc. of the construction information can be superimposed and displayed on the node on the position information 520 corresponding to its construction length.

[0080] Back to Figure 3 , the distribution unit 114 of the server device 100 distributes (publishes) the distribution information 500 generated by the distribution information generation unit 113 to the network 300. As a result, the information acquisition unit 211 of the client device 200 can access the server device 100 via the network 300 and obtain the distributed distribution information 500 (displayed on the display of the client device 200). In addition, the construction information management system 1 can be configured as follows: for example, only users limited to the construction company can access the distribution information 500.

[0081] The user of the client device 200 can intuitively recognize the simple construction information 530 associated with the desired position of the map information 510 while operating the map information 510 of the distribution information 500. For example, when the user is considering road construction, he or she obtains the distribution information 500 in advance and confirms whether there is construction information of the road. In this way, if there is construction information of past construction on the road scheduled for construction, the user can easily obtain the information. In this way, the user can easily recognize the state of the road before the road construction.

[0082] Furthermore, the following configuration may be adopted: when the user of the client device 200 wishes to obtain more detailed information on a road scheduled for construction, the user may send a request for providing information to the server device 100, and receive detailed construction information as provided information from the server device 100. For example, when a construction company decides to carry out road construction, the user of the construction company accesses the server device 100 and obtains detailed construction information in order to obtain detailed information on the road. Alternatively, a road management group may use the detailed construction information to determine whether to carry out road construction.

[0083] The request information generation and output unit 212 of the client device 200 generates the request information under the operation of the user and transmits it to the server device 100. Upon receiving the request information from the client device 200, the request information acquisition unit 115 of the server device 100 determines the client device 200 to which the detailed construction information is to be transmitted. Furthermore, the detailed information generation unit 116 generates the detailed construction information to be transmitted to the client device 200.

[0084] The detailed construction information can read the actual construction information registered in the database DB and use the actual construction information as it is, or extract the required information from the actual construction information and generate the detailed construction information. The detailed construction information preferably includes the construction position, construction length, construction width and construction thickness as the construction information during the past road construction. In addition, the detailed construction information can also include information such as construction machinery, paving materials, construction tracks, construction speed and the state of the road after construction. This is because this information may also be used in the current road construction.

[0085] When the detailed construction information is generated by the detailed information generating unit 116, the information transmitting unit 117 of the server device 100 transmits the detailed construction information to the client device 200. Thus, the information acquiring unit 211 of the client device 200 can smoothly acquire the detailed construction information.

[0086] The user of the client device 200 can generate a construction plan for the road this time using the detailed construction information (or distribution information 500) received from the server device 100. At this time, the client device 200 can generate a construction plan for the road this time by using the construction information of the road constructed in the past, the construction scope of the road this time, and the information of the construction machine 10 used this time through the construction plan generation unit 213. As an example, the construction plan for the road can include the construction information of the road in the past, the construction scope of the road this time, the target construction track and target construction speed of the construction machine 10 calculated based on the construction machine 10 used this time, etc. In addition, when generating a construction plan, the construction scope of the road in the past and the construction scope of the road this time can be slightly deviated. This is because, even in this case, it is possible to fully grasp the status of the road scheduled for construction using the information of the same degree of construction scope in the past.

[0087] Then, Figure 3The pre-construction information output unit 214 extracts the target construction information that can be input to the construction machine 10 in the current road construction plan generated by the construction plan generation unit 213 and outputs it to the construction machine 10. For example, when the construction machine 10 is automatically operated, the target construction information includes information on the target construction track and the target construction speed. If the construction machine 10 receives the target construction track and the target construction speed from the client device 200, it can actually use the received construction track and construction speed to perform operations in this road construction.

[0088] The construction information management system 1 according to the embodiment is basically configured as described above, and its operation (construction information management method) will be described below.

[0089] Figure 6 1 is a flowchart illustrating the processing flow of the server device 100 when acquiring construction information from the work site CP. Figure 6 As shown, the server device 100 acquires construction information (actual construction information) from a work site CP where a construction machine 10 is performing road construction via the construction information acquisition unit 111 (step S101 ).

[0090] Thus, the database processing unit 112 of the server device 100 processes the acquired construction information and registers it in the database DB managed by the server device 100 (step S102). In this way, the server device 100 can centrally manage a plurality of construction information by storing the construction information of a plurality of work sites CP.

[0091] The distribution information generation unit 113 of the server device 100 generates the distribution information 500 in advance and associates the construction information in the database DB with the distribution information 500, thereby updating the distribution information 500 (step S103). The time of updating the distribution information 500 is not particularly limited, and examples thereof include the time of registering the construction information in the database DB, updating at each set period, or updating at each set registration quantity.

[0092] Then, the server device 100 distributes the generated distribution information 500 to the network 300 via the distribution unit 114 (step S104 ). Thus, users of the use location UP such as a construction company can use the distribution information 500 using the client device 200 .

[0093] Figure 7 2 is a flowchart illustrating the sequence of information communication between the server device 100 and the client device 200. Figure 7 As shown, the construction information management system 1 provides a service of distributing distribution information 500 from the server device 100 to the client device 200 .

[0094] Specifically, the client device 200 accesses the server device 100 via the network 300 under the operation of the user (step S201 ).

[0095] Thus, the server device 100 distributes the distributed distribution information 500 to the client device 200 (step S202). The distribution information 500 is based on Figure 5 The map information 510 shown is distributed to the client device 200 . Therefore, the user can perform operations such as zooming in, zooming out, and sliding the map information 510 on the client device 200 .

[0096] Then, the client device 200 allows the user to operate the distribution information 500 and designate an arbitrary position in the map information 510 (step S203). Designation of the position is, for example, an operation in which the user places a cursor on the display at the position information 520 superimposed on the map information 510.

[0097] When receiving the arbitrary position designated by the user, the server device 100 distributes the simple construction information 530 corresponding to the arbitrary position and displays it on the display of the client device 200 (step S204). Thus, the user can easily recognize the simple construction information 530 of the distributed information 500.

[0098] Furthermore, in the client device 200 , when it is desired to obtain detailed construction information, the request information generation and output unit 212 generates request information and transmits the request information to the server device 100 (step S205 ).

[0099] When receiving the request information, the server device 100 generates corresponding detailed construction information and sends the detailed construction information to the client device 200 (step S206). Thus, for example, the user of the client device 200 can recognize and examine the construction information of the road in advance based on the detailed construction information of any location.

[0100] Furthermore, the client device 200 can generate a construction plan for the construction scope of the road to be constructed based on the detailed construction information obtained from the server device 100. For example, the construction plan generation unit 213 of the client device 200 calculates the target construction information (target construction track, target construction speed) of the construction machine 10 in the current road construction based on the information included in the detailed construction information (step S207).

[0101] Figure 8 is a diagram illustrating a target construction track generated in the client device 200. For example, Figure 8As shown, the construction plan generation unit 213 of the client device 200 generates a plan view 600 having a construction range 601 of the current road. The construction information management system 1 may also be configured to assist the client device 200 in generating the plan view 600 by attaching the map information 510 of the construction range to the detailed construction information sent from the server device 100. Furthermore, when generating the plan view 600, the construction plan generation unit 213 may display the difference between the current road construction range and the past road construction range by superimposing the past construction range 602 of the detailed construction information on the current construction range 601.

[0102] If the plan view 600 is prepared, the construction plan generation unit 213 calculates the construction tracks and construction speeds of various construction machines 10 based on the plan view 600. At this time, the construction plan generation unit 213 refers to the actual construction information of the past roads. For example, when the construction scope 601 of the current road is the same, the construction track or construction speed of the past road can be used. And, for example, when the construction scope of the current road deviates from the construction scope of the past road, the construction track of the past road is extended or shortened, and the construction speed of the part deviating from the past construction scope is changed. In this way, the construction plan generation unit 213 can obtain the construction track 603 and construction speed corresponding to the current construction scope 601.

[0103] Back to Figure 7 The target construction information (target construction track 603, target construction speed) generated by the construction plan generation unit 213 is sent to the construction machine 10 by the pre-construction information output unit 214 as target construction information (step S208). As a result, the construction machine 10 can accurately perform operation support control such as automatic operation according to the target construction track 603 and target construction speed corresponding to the construction range of the road this time.

[0104] In addition, the construction information management system 1 is not limited to using the actual construction information of the past roads stored in the database DB as described above for the current road construction. For example, the construction information of the past roads can be used for the automatic operation of the vehicles actually traveling on the roads. As an example, the following can be cited: the server device 100 sends the construction information to the vehicles traveling on the roads, and notifies the vehicles of the unevenness of the roads and / or the state of the asphalt, thereby facilitating the processing of the automatic operation of the vehicles.

[0105] Hereinafter, the technical idea and effects of the present invention described in the above embodiments will be described.

[0106] The first method of the present invention includes: a construction machine 10, which performs road construction; a server device 100, which obtains construction information when the construction machine 10 performs road construction and stores it in a database DB; and a client device 200, which is connected to the server device 100 for information communication. In the above-mentioned construction information management system 1, the server device 100 sends provision information including part or all of the construction information during road construction stored in the database DB to the client device 200 based on the access of the client device 200.

[0107] According to the above, the construction information management system 1 can receive the provided information including the construction information when the road is being constructed from the server device 100 by the client device 200 accessing the server device 100. Thus, the construction information when the road is being constructed by the construction machine 10 can be appropriately used in the client device 200. For example, the user of the client device 200 can make a construction plan for this road based on the construction information of the past road. As a result, the preliminary preparation for construction can be greatly reduced, and the working hours of the staff can be reduced. That is, the construction information management system 1 can use the construction information of the past road, thereby improving the convenience of the user.

[0108] Furthermore, the construction information includes information on the road construction location and the road construction content. Thus, the construction information management system 1 can provide the construction location and construction content to the user of the client device 200. The user of the client device 200 can recognize the road construction status based on the construction location and construction content.

[0109] The road construction content information includes the model of the construction machine 10 and the detection information detected by the detection sensors 27 and 37 of the construction machine 10 when the construction machine 10 performs road construction. Thus, the construction information management system 1 can use the detection information during actual construction, such as when constructing a new road.

[0110] Furthermore, the detection information includes information on the construction track and construction speed when the construction machine 10 is performing road construction. Thus, the user of the client device 200 can infer the state of the road based on the construction track and / or construction speed during actual construction, and can use the construction track and / or construction speed when constructing a new road.

[0111] Furthermore, the server device 100 generates distribution information 500 as provided information, which associates a plurality of pieces of construction information (simple construction information 530) during road construction stored in the database DB with the map information 510, and distributes the distribution information 500 to the network 300 accessible to the client device 200. Thus, the construction information management system 1 can easily obtain the distribution information 500 associated with the construction information during road construction by accessing the server device 100 from the client device 200.

[0112] Furthermore, the server device 100 causes the client device 200 to display the road construction information associated with the map information 510 according to the operation of the distribution information 500 in the client device 200. Thus, the user of the client device 200 can smoothly obtain the road construction information in the map information 510 by intuitively operating the map information 510.

[0113] The client device 200 generates a construction track of the construction machine 10 in the current road construction based on the construction information of the past road construction included in the provided information. Thus, the construction machine can efficiently and accurately perform road construction along the generated construction track.

[0114] Furthermore, the construction information management system 1 has a work site terminal 50, which obtains the construction information detected by the construction machine 10 during road construction and sends it to the server device 100. Thus, the construction information management system 1 can process (select, choose, etc.) the detection information of the construction machine 10 that has constructed the road, and send the required information to the server device 100, thereby achieving the effect of reducing the load on the server device 100.

[0115] Furthermore, the second aspect of the present invention includes the following steps: obtaining construction information when the construction machine 10 performs road construction in the server device 100; storing the construction information when the road construction is performed in the database DB in the server device 100; and sending provision information including a part or all of the construction information when the road construction is performed stored in the database DB to the client device 200 in response to access by the client device 200. Even in this case, the construction information management method can improve convenience by being able to appropriately utilize the construction information when the construction machine 10 performs road construction.

[0116] The construction information management system involved in the embodiments disclosed this time is illustrative in all points and is not restrictive. The embodiments can be modified and improved in various ways without departing from the scope and purpose of the technical solution. The matters recorded in the above-mentioned multiple embodiments can adopt other structures within the scope of non-contradiction, and can be combined within the scope of non-contradiction.
