Description

[Technical Field]

[0001] The present invention relates to a work management system and a work management method for construction machinery. [Background technology]

[0002] Traditionally, construction progress and work completion rates at construction sites have been confirmed by construction managers who physically inspect the construction status and take notes, and the accuracy of the progress confirmation has depended on the experience and know-how of the construction managers. In order to eliminate this variation in the accuracy of progress confirmation due to individual experience, one possible method is to use image recognition processing to check the operating status of various construction machinery.However, with image recognition processing, it is difficult to determine the operating times and operating areas of various construction machinery, and when the same type of construction machinery is operating at the same time, it is extremely difficult to distinguish between the different construction machinery, making this method unlikely to be an effective management method.

[0003] Here, Patent Document 1 proposes a tunnel construction process recording device and construction process recording method that quickly record information based on tunnel construction processes at any time without relying on manual work. This tunnel construction process recording device has an information acquisition unit that acquires electricity usage information corresponding to each device or device group in chronological order from the power sources of multiple devices used in tunnel construction, a process determination unit that analyzes the electricity usage information acquired in chronological order by the information acquisition unit and determines the corresponding tunnel construction process, and a process information recording unit that records information based on the tunnel construction process determined by the process determination unit. In the tunnel construction process recording device, the waveform of the electric energy obtained when using a device or group of devices is predetermined as a reference waveform, and the process determination unit compares the waveform of the electric energy obtained in chronological order with the reference waveform, estimates that the device or group of devices linked to the reference waveform that most closely resembles the waveform of the electric energy obtained in chronological order is being used, and determines that the process using the linked device or group of devices is the corresponding tunnel construction process. In addition, when the process determination unit obtains a cyclic power waveform pattern from the electricity usage information obtained in chronological order using a pattern recognition technique, it sets the waveform pattern as a reference waveform for the tunnel construction process corresponding to the equipment or group of equipment operating at the time of acquisition, and thereafter, when it detects an electric power waveform corresponding to the reference waveform from the electric power waveforms obtained from the electricity usage information obtained in chronological order, it determines that it is the corresponding tunnel construction process.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-27097 Summary of the Invention [Problem to be solved by the invention]

[0005] The tunnel construction process recording device described in Patent Document 1 requires that a reference waveform, which is the waveform of the amount of power, be determined in advance for each piece of equipment or group of equipment, and therefore the number of reference waveforms to be set increases depending on the number and type of equipment, leaving room for improvement in terms of less hassle and more efficient work management.

[0013] In another aspect of the work management system for construction machines according to the present invention, The server device a storage unit that stores a database relating to the type of construction machine and the work content specific to the construction machine, in which the position information and the electricity usage information of each of the position / operation information signals are linked to the ID specific to the position / operation information signal; an identification unit that collates the ID of the position / operation information signal received from the transmitter with the database to identify work progress information included in the work information; The device is characterized by comprising a communication unit that receives the position / operation information signal transmitted from the transmitter and transmits the work information signal to the management terminal.

[0014] According to this aspect, the server device stores the location information and electricity usage information based on the location / operation information signal as a database relating to the type of construction machine linked to an ID unique to the location / operation information signal and the work content unique to this construction machine, and the ID-assigned location / operation information signal and the database are referenced to identify the type of construction machine and its work progress information, which is then sent to the management terminal as a work information signal, thereby enabling the identification of the work progress information of the construction machine to be performed highly accurately and efficiently, and allowing, for example, multiple people involved in the construction work to simultaneously share the work progress information of each construction machine.

[0015] Furthermore, one aspect of the construction machine work management method according to the present invention is to Step A includes a location information acquisition means and a transmitter electrically connected to a main power switch of the construction machine, and the transmitter transmits a location and operation information signal including location information and electricity usage information of the construction machine to a server device; Step B: in the server device, work information of the construction machine is identified based on the received position / operation information signal, and a work information signal relating to the work information is transmitted to a management terminal; The method is characterized by having a step C of displaying work information of the construction machine on the management terminal based on the received work information signal.

[0019] Hereinafter, a construction machine work management system and a work management method according to an embodiment will be described with reference to the accompanying drawings. Note that in this specification and the drawings, substantially identical components will be designated by the same reference numerals, and redundant explanations may be omitted.

[0020] [Construction Machine Work Management System and Work Management Method According to the Embodiment] An example of a work management system and a work management method for a construction machine according to an embodiment will be described with reference to Figures 1 to 6. Here, Figure 1 is a diagram showing an example of the overall configuration of a work management system for a construction machine according to an embodiment, and Figure 2 is a diagram showing an example of a circuit diagram in which a main power switch, a transmitter, and a position information acquisition means are electrically connected.

[0021] The illustrated construction machinery work management system 70 includes multiple types of construction machinery 10, a server device 50 that receives, via a network 40, position and operation information signals including the position information and electricity usage information of the construction machinery 10 transmitted from a transmitter 30 mounted on each construction machinery 10, and a management terminal 60 that receives, via the network 40, work information signals related to work information of the construction machinery 10 transmitted from the server device 50. Here, the illustrated server device 50 is a cloud server device. There may be multiple management terminals 60, and the multiple management terminals 60 may include a management computer (management terminal 60A) in a management building at the construction site, smartphones or tablets carried by, for example, multiple construction managers at the construction site, and computers (management terminal 60B) in related departments at head office or branch offices.

[0022] The construction machines 10 shown in the figure are a bulldozer 10A, a vibrating roller 10B, a dump truck 10C, and a welding machine 10D, each equipped with its own transmitter 30A, 30B, 30C, and 30D. The construction machines are not limited to the examples shown in the figure, and include a variety of construction machines depending on the type of work, such as cranes, excavators, rock drills, and tunnel boring machines.

[0023] Here, the electrical connection configuration of each component of the construction machine 10 will be described with reference to FIG.

[0024] A signal circuit 15 is connected to the main power switch 20 of the construction machine 10, and is connected to a power source 16 via the signal circuit 15. A GPS (an example of a location information acquisition means) that identifies the location information of the construction machine 10 is also connected to the signal circuit 15. A transmitter 30 is connected midway through the signal circuit 15. Here, Wi-Fi, Beacon, or the like may be used as the location information acquisition means.

[0025] The transmitter 30 of each construction machine 10 is assigned a unique ID, and therefore, position and operation information signals with the assigned ID are transmitted from each transmitter 30 to the server device 50.

[0026] Here, the electricity usage information of the construction machine 10, which is the source of the operation information signal, includes the time and time period when the main power switch 20 is turned on. As will be described in detail below, the server device 50 identifies the corresponding transmitter 30 and construction machine 10 based on the ID of the received position / operation information signal, identifies the work information of the construction machine 10 based on the position / operation information signal corresponding to the transmitter 30, and transmits a work information signal related to the work information to the management terminal 60.

[0027] Next, an example of the hardware configuration of the server device 50 and the management terminal 60 will be described with reference to FIG. 3, and an example of the functional configuration of the server device 50 will be described with reference to FIG.

[0028] As shown in FIG. 3, both the server device 50 and the management terminal 60 are configured by information processing devices (computers) such as personal computers (PCs).

[0029] The computer that constitutes the server device 50 and the management terminal 60 includes a CPU (Central Processing Unit) 51, a main memory device 52, an auxiliary memory device 53, an input / output IF (interface) 54, and a communication IF 55, which are interconnected by a connection bus 56. The main memory device 52 and the auxiliary memory device 53 are computer-readable recording media. Note that the above components may be provided separately, or some of the components may not be provided.

[0030] The CPU 51 is also called an MPU (Microprocessor) or a processor, and may be a single processor or a multiprocessor. The CPU 51 is a central processing unit that performs overall control of the server device 50 and the management terminal 60, which are made up of computers. The CPU 51, for example, deploys a program stored in the auxiliary storage device 53 in an executable form in the working area of ​​the main storage device 52, and controls peripheral devices through the execution of the program, thereby providing functions that meet a predetermined purpose.

[0031] The main memory device 52 stores computer programs executed by the CPU 51, data processed by the CPU 51, etc. The main memory device 52 includes, for example, a flash memory, a RAM (Random Access Memory), and a ROM (Read Only Memory). The auxiliary memory device 53 stores various programs and various data on a readable and writable recording medium, and is also called an external memory device. The auxiliary memory device 53 stores, for example, an OS (Operating System), various programs, various tables, etc. The OS includes, for example, a communication interface program that exchanges data with external devices connected via the communication IF 55. The external devices for the server device 50 include the transmitter 30 and the management terminal 60, and the external devices for the management terminal 60 include, in addition to the server device 50, smartphones and tablets carried by operators of the construction machines 10 and construction managers at the construction site.

[0032] The auxiliary storage device 53 is used, for example, as a storage area that supplements the main storage device 52, and stores computer programs executed by the CPU 51, data processed by the CPU 51, etc. The auxiliary storage device 53 is a silicon disk including nonvolatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD: Hard Disk Drive), a solid state drive, etc. Examples of the auxiliary storage device 53 include drives for removable recording media such as CD drives, DVD drives, and BD drives, and examples of the removable recording media include CDs, DVDs, BDs, USB (Universal Serial Bus) memories, and SD (Secure Digital) memory cards.

[0033] The input / output IF 54 is an interface for inputting and outputting data between the server device 50 and devices connected to the management terminal 60. Input devices such as a keyboard, a touch panel, a mouse or other pointing device, and a microphone are connected to the input / output IF 54. Both the server device 50 and the management terminal 60 receive, via the input / output IF 54, operation instructions and the like from an operator who operates an input device.

[0034] In addition, display devices such as a liquid crystal display (LCD) panel or an organic electroluminescence (EL) panel, as well as output devices such as a printer and a speaker, are connected to the input / output IF 54. The management terminal 60 is configured to display, for example, specific work information of the construction machine 10 at a specific construction site.

[0035] The communication IF 55 is an interface with the network 40 to which the server device 50 is connected. The communication IF 55 receives position / operation information signals with IDs assigned from the transmitter 30 via various networks 40, such as public networks such as the Internet, wireless networks such as mobile phone networks, dedicated networks such as VPNs (Virtual Private Networks), and LANs (Local Area Networks), and similarly transmits work information signals of the construction machines 10 corresponding to the position / operation information signals to the management terminal 60 via the network 40.

[0036] The communication IF 55 may also be an LPWA wireless communication module, and major LPWA communication methods (communication protocols) include Sigfox, LoRaWAN (Long Range Wide Area Network), and NB-IoT. LoRaWAN is a communication method that uses the 920 MHz ISM band and employs LoRa modulation, enabling long-distance communication even at low output power of 13 dBm or less. As mentioned above, among the various communication protocols, it is preferable to use private LoRa, which does not require a license, allows for the installation of private base stations inside tunnels (an example of a construction site) even in mountainous areas where mobile phone signals are difficult to reach, and allows for the construction of low-cost communication systems.

[0037] The communication IF 55 receives work information signals regarding work information of the construction machine 10 from the server device 50 via the network 40 to which the management terminal 60 is connected, and transmits the work information signals to smartphones, tablets, etc. carried by construction personnel who manage work on the construction machine 10 at the construction site.

[0038] 4, the server device 50 provides various functions of at least a communication unit 510, an identification unit 520, a display unit 530, and a storage unit 540 by executing a program by a CPU 51. Here, at least a part of the processing functions may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), or the like, and similarly, at least a part of the processing functions may be provided by a dedicated LSI (Large Scale Integration) such as an FPGA (Field-Programmable Gate Array), a numerical calculation processor, an image processing processor, or other digital circuits, or the like.

[0039] The communication unit 510 receives position and operation information signals, each having a unique ID attached thereto, transmitted from each transmitter 30 as needed, and stores the received signals in the storage unit 540 as needed.

[0040] The storage unit 540 stores a database relating to the type of construction machine 10 and the work content specific to the construction machine 10, in which the position information and electricity usage information of each of the multiple types of position / operation information signals (in the illustrated example, position / operation information signals transmitted from transmitters 30A, 30B, 30C, and 30D) is linked to an ID unique to the position / operation information signal.

[0041] Here, the types of construction machinery 10 include, as mentioned above, bulldozers, dump trucks, cranes, etc., and the work content specific to the construction machinery 10 includes leveling earth and sand in the case of bulldozers, and transporting earth and sand in the case of dump trucks.

[0042] Since multiple construction machines 10 are operating at a particular construction site, the database includes all the IDs of the transmitters 30 installed on each construction machine 10, and the work content of the construction machine 10 corresponding to each transmitter 30 is added.

[0043] The identification unit 520 compares the ID of the position / operation information signal received from the transmitter 30 with the construction machine and its work details stored in the database, and identifies the work information.

[0044] Here, the work information includes work progress information. For example, the work information may specify that the type of construction machine 10 is a bulldozer, that it is being used for earthwork in work area X on year, month, and day at the XX construction site, that the work time is 8:00 AM to 3:00 PM, and that the distance traveled is 200 m. Then, based on the leveled area (or leveled volume) per meter of the bulldozer's travel, the total leveled area (or total leveled volume) of the bulldozer is specified as work progress information. Furthermore, based on the location information signal, the detailed work area in work area X of the bulldozer that is the subject of work management is also specified.

[0045] The display unit 530 displays the work information of the identified construction machine 10. Here, since the work information displayed on the display unit 530 of the server device 50 is not directly checked by people involved in the construction work who are located remotely (people involved in the construction work check the work information of each construction machine 10 on the display unit of their own management terminal 60), the server device 50 does not need to be equipped with the display unit 530.

[0046] The communication unit 510 transmits a work information signal relating to the work information of the construction machine 10 identified by the identification unit 520 to the management terminal 60. Here, the management terminal 60 is an associated computer that has access authority to the server device 50, and multiple management terminals 60 that have been granted access authority can share various data.

[0047] Although not shown in the figure, each management terminal 60 has at least a communication unit and a display unit. A work information signal relating to work information of the construction machine 10 is received from the server device 50 via the communication unit.

[0048] The work information of the construction machine 10 based on the received work information signal is displayed on the display unit of the management terminal 60.

[0049] According to the construction machinery work management system 70, a transmitter 30 is electrically connected to the main power switch 20 equipped on each construction machine 10, and the work information of the construction machine 10 is identified by the server device 50 based on the position / operation information signal transmitted from the transmitter 30, which includes the position information and electricity usage information of the construction machine 10, and the work information signal related to the work information is received and displayed on the management terminal 60, so that the position information and operation information specific to each construction machine 10 can be identified with high accuracy, and work management of each construction machine 10 (the work location and work progress of each construction machine) can be carried out with high accuracy and efficiently.

[0050] Furthermore, by transmitting a work information signal relating to the work information of each construction machine 10 from the server device 50 to each management terminal 60, multiple people involved in the construction work can share the work information of each construction machine 10 in real time.

[0051] The construction machine work management method according to the embodiment includes the following steps A to C.

[0052] In step A, the construction machine 10 is equipped with a location information acquisition means 17 and a transmitter 30 electrically connected to the main power switch 20, and a location / operation information signal including the location information and electricity usage information of the construction machine 10 is transmitted from the transmitter 30 to the server device 50.

[0053] In step B, the server device 50 identifies the work information of the construction machine 10 based on the received position / operation information signal, and transmits a work information signal relating to the work information to the management terminal 60.

[0054] In step C, the work information of the construction machine 10 is displayed on the management terminal 60 based on the received work information signal.

[0055] Next, an example of work information for a construction machine displayed on the display unit (display screen) of the management terminal 60 will be described with reference to Figures 5 and 6. Here, each figure is a time series diagram showing an example of work information for a construction machine.

[0056] 5 is work information for various construction machines in a dam body concrete work at a certain construction site. The construction machines in the illustrated example are Polyrobo (a polisher robot), cranes 1 and 2, a wheel loader, and a buyback.

[0057] Based on the operating time and movement amount of the buyback, the amount of concrete poured is identified as work progress information, based on the operating time and movement amount of one of the cranes, the amount of work done by the sliding formwork (area of ​​concrete poured) is identified as work progress information, and based on the operating time and movement amount of the polyrobot, the amount of laitance processing at the joint surface is identified as work progress information.

[0058] 6 shows work information for various construction machines in earthworks at a certain construction site. The construction machines shown in the figure are a bulldozer, dump trucks 1, 2, and 3, and a vibratory roller.

[0059] The amount of soil leveled is identified as work progress information based on the operating time and movement amount of the bulldozer, the amount of soil transported is identified as work progress information based on the operating time and movement amount of each dump truck 1, 2, 3, and the compacted area of ​​soil is identified as work progress information based on the operating time and movement amount of the vibratory roller.

[0060] It should be noted that the present invention is not limited to the configurations shown here, and other embodiments may be possible in which other components are combined with the configurations described in the above embodiments. In this regard, the present invention can be modified within the scope of the present invention, and can be appropriately determined depending on the application form. [Explanation of symbols]
