Description

[Technical Field]

[0001] The present invention relates to a technology for remote management of wastewater generated from cutting machines in pavement cutting operations. [Background technology]

[0002] When cutting asphalt or concrete pavement, wastewater containing cutting powder and blade cooling water from the cutting machine is generated. This wastewater is generally called "cutter wastewater."

[0003] Cutter wastewater is an industrial waste, and from the viewpoint of preventing water pollution, it is necessary to collect and treat it appropriately. For this reason, cutting machines equipped with a cutter wastewater suction function that sucks up cutter wastewater by vacuum are known (for example, Patent Document 1).

[0004] In the cutting machine described in Patent Document 1, a blade cooling water tank mounted on a vehicle is connected to the cutting machine by a blade cooling water supply pipe. The blade cooling water in the blade cooling water tank flows through the blade cooling water supply pipe and is supplied to the cutting machine. Furthermore, the cutter drainage water tank mounted on the vehicle is connected to the cutting machine by a cutter drainage recovery pipe. The cutter drainage water collected by the cutter drainage suction function of the cutting machine flows through the cutter drainage recovery pipe and is stored in the cutter drainage water tank.

[0005] According to the cutting machine described in Patent Document 1, cutter wastewater can be collected in a cutter wastewater storage tank, so the collected cutter wastewater can be taken to a treatment plant for treatment. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 4045079 (paragraphs 0017 to 0019, Figures 1 and 2) Summary of the Invention [Problem to be solved by the invention]

[0007] From the viewpoint of appropriate cutter drainage recovery, the supply flow rate of blade cooling water and the recovery flow rate of cutter drainage during cutting machine operation are important management items in pavement cutting work. Furthermore, because the total amount of blade cooling water that can be loaded onto a vehicle and brought to the site is limited due to tank capacity, it is necessary to manage the remaining amount of blade cooling water when the cutting machine is in operation.

[0008] In addition, some of the cutter wastewater generated when cooling the rotating, heated blades of the cutting machine inevitably evaporates or is absorbed around the cut section of the pavement, but it is desirable to minimize the amount of cutter wastewater that goes unrecovered. Therefore, it is desirable to maintain the cutter wastewater recovery rate, which is the ratio of the recovered cutter wastewater flow rate to the supplied blade cooling water flow rate, at a predetermined value or higher.

[0009] However, Patent Document 1 does not mention the management of the remaining amount of blade cooling water in the blade cooling water tank, the flow rate of blade cooling water supplied, the flow rate of recovered cutter wastewater, and the cutter wastewater recovery rate. Furthermore, these management items related to cutter wastewater are currently managed separately at multiple pavement cutting work sites. As a result, efficiency across multiple pavement cutting work sites is not being improved. Furthermore, data on management items related to cutter wastewater is not properly stored.

[0010] Therefore, the present invention aims to solve the above problem by providing a cutter drainage remote management system that can remotely monitor the above management items related to cutter drainage-related equipment at multiple pavement cutting work sites from a centralized management center. [Means for solving the problem]

[0011] The cutter drainage remote management system of the first invention is a cutter drainage remote management system in which cutter drainage related devices for cutting machines used at multiple pavement cutting work sites and a cutter drainage management server that manages operating information of the cutter drainage related devices are connected to each other via a communication network so as to be able to communicate data, wherein the cutter drainage related devices comprise: a blade cooling water flow rate measuring means that measures the flow rate of blade cooling water supplied to cool the blades of the cutting machine; a cutter drainage flow rate measuring means that measures the flow rate of cutter drainage recovered from the cutting machine; a blade cooling water level measuring means that measures the level of blade cooling water in a blade cooling water tank; and a cutter drainage related device side data communication means that exchanges data with the cutter drainage management server, and the cutter drainage management server comprises: a server side data communication means that exchanges data with the cutter drainage related devices; a cutter drainage recovery rate calculation means that acquires the blade cooling water flow rate and the cutter drainage flow rate and calculates the cutter drainage recovery rate; and a cutter drainage management item display means that displays cutter drainage management items consisting of the blade cooling water flow rate, the cutter drainage flow rate, the blade cooling water level, and the cutter drainage recovery rate, etc.

[0012] The cutter drainage remote management system according to the first aspect of the present invention allows a centralized management center to remotely monitor the cutter drainage management items at multiple pavement cutting work sites, thereby improving the efficiency of the entire multiple pavement cutting work sites. Furthermore, data on management items related to cutter drainage can be appropriately stored. In addition, by remotely monitoring the remaining amount of blade cooling water from a centralized control center, a blade cooling water transport vehicle can be dispatched in a timely manner to a pavement cutting work site where the remaining amount of blade cooling water is low in order to replenish the blade cooling water.

[0013] The cutter wastewater remote management system of the second invention is characterized in that the cutter wastewater-related device further includes a cutter wastewater recycling means for filtering and dewatering the collected cutter wastewater and separating it into treated water and solids, thereby reusing the cutter wastewater.

[0014] The cutter wastewater remote management system according to the second aspect of the present invention can reuse cutter wastewater using the cutter wastewater recycling means, thereby significantly extending the time between dispatches for additional replenishment of blade cooling water. In addition, since cutter wastewater can be treated at the pavement cutting site, there is no need to take the collected cutter wastewater to a wastewater treatment facility.

[0015] The cutter drainage remote management system of the third invention is characterized in that the cutter drainage related device further comprises a buried metal object detection means installed on the cutting machine for detecting buried metal objects in the pavement in the direction of travel of the cutting machine, and an alarm means installed on the cutting machine for issuing an alarm, and when a buried metal object is detected, an alarm is issued by the alarm means and a notification that a buried metal object has been detected is sent to the cutter drainage management server.

[0016] The cutter drainage remote management system according to the third invention issues an alarm when it detects buried metal objects in the pavement in the direction of travel of the cutting machine, preventing accidents where buried metal objects are accidentally cut. Detection of buried metal objects can also be remotely managed. This can further improve the overall efficiency of multiple pavement cutting work sites. [Effects of the Invention]

[0017] According to the present invention, the operating status of cutter drainage-related devices at multiple pavement cutting work sites can be remotely monitored from a centralized control center, thereby improving efficiency across multiple pavement cutting work sites. In addition, data on management items related to cutter drainage can be appropriately stored and used. Furthermore, by remotely monitoring the remaining amount of blade cooling water from a centralized control center, a blade cooling water transport vehicle can be dispatched in a timely manner to a pavement cutting work site where the remaining amount of blade cooling water is low in order to replenish the blade cooling water.

[0019] Hereinafter, an embodiment of a cutter drainage remote management system according to the present invention will be described with reference to the drawings.

[0020] [Overall schematic configuration of the cutter drainage remote management system] FIG. 1 shows a schematic overall configuration of a cutter drainage remote management system 1 according to the present invention. The cutter drainage remote management system 1 comprises a cutter drainage management server 2 installed in a centralized management center, and cutter drainage-related devices 3 at multiple pavement cutting work sites (pavement cutting work site 1, pavement cutting work site 2, pavement cutting work site 3, etc.). The cutter drainage management server 2 and the cutter drainage-related devices 3 are connected to each other so that data communication is possible via a communication network N. Note that the number of pavement cutting work sites that make up the cutter drainage remote management system 1 is not particularly limited.

[0021] The cutter drainage-related device 3 supplies blade cooling water used to cool the blades of the cutting machine 4 used at the pavement cutting work site. The cutter drainage-related device 3 also collects cutter drainage water from the cutting machine 4. The cutter drainage-related device 3 and the cutting machine 4 are connected by a hose 5 or the like for supplying blade cooling water and collecting cutter drainage water.

[0022] [First embodiment] (System configuration) 2 shows a detailed system configuration of the cutter drainage remote management system 10 according to the first embodiment. The cutter drainage-related device 11 according to the first embodiment has the following configuration.

[0023] A blade cooling water tank 13 mounted on a vehicle 12 is connected to the cutting machine 4 by a blade cooling water supply pipe 14. Blade cooling water 15 in the blade cooling water tank 13 is sent to the blade 16 of the cutting machine 4 through the blade cooling water supply pipe 14. The arrows in the figure indicate the direction in which the blade cooling water 15 flows.

[0024] When the rotating blade 16 cuts the asphalt or concrete pavement 17, cutter wastewater containing a mixture of blade cooling water and cutting powder is generated. The cutter wastewater is sucked out by the vacuum suction function of the cutting machine 4.

[0025] The cutting machine 4 and a cutter drainage water tank 18 mounted on the vehicle 12 are connected by a cutter drainage recovery pipe 19. Cutter drainage water 20 collected by the cutter drainage suction function of the cutting machine 4 passes through the cutter drainage recovery pipe 19 and is stored in the cutter drainage water tank 18. The arrows in the figure indicate the flow direction of the cutter drainage water 20.

[0026] A programmable logic controller 22 (hereinafter abbreviated as "PLC22") shown in FIG. 2 is used to perform sequence control of the cutter / drainage related device 11.

[0027] FIG. 3 shows the functional configuration of the PLC 22. As shown in FIG. 3, the PLC 22 is configured to include a control unit 31, an operation unit 32, an input unit 33, a RAM 35, a memory unit 36, an output unit 38, a calculation unit 39, etc., and each unit is connected by a bus 37.

[0028] The control unit 31 is composed of a CPU (Central Processing Unit) and the like, and comprehensively controls the processing operations of each unit of the PLC 22. Specifically, the CPU reads out various processing programs stored in the storage unit 36 ​​in response to operation signals input from the operation unit 32 or input signals received by the input unit 33, loads them into the RAM 35, and performs various processes in cooperation with the programs.

[0029] The RAM 35 stores various programs read from the storage unit 36, parameters and files required for executing the programs, etc., in various processes executed by the control unit 31. The output unit 38 outputs the results of the processes executed by the control unit 31.

[0030] As shown in Figure 2, a flow rate sensor 21 is installed in the blade cooling water supply pipe 14. The flow rate sensor 21 can be installed by being clamped to the blade cooling water supply pipe 14. The flow rate sensor 21 can measure the flow rate (liters per minute) regardless of the type of fluid, even if the flow is pulsating. The flow rate sensor 21 and the PLC 22 are connected by a signal line 23. The flow rate sensor 21 in the blade cooling water supply pipe 14 and the PLC 22 constitute a blade cooling water flow rate measurement means 40.

[0031] 2, a flow rate sensor 21 is also installed in the cutter wastewater recovery pipe 19. The flow rate sensor 21 and the PLC 22 are connected by a signal line 24. The flow rate sensor 21 of the cutter wastewater recovery pipe 19 and the PLC 22 constitute a cutter wastewater flow rate measuring means 41.

[0032] As shown in Figure 2, a liquid level sensor 25 is installed in the blade cooling water tank 13. The liquid level sensor 25 detects the liquid level using a pulse signal when a probe (sensing unit) is inserted into the liquid. The liquid level sensor 25 can measure the liquid level regardless of the type of fluid. The liquid level sensor 25 and the PLC 22 are connected by a signal line 26. The liquid level sensor 25 and the PLC 22 constitute the blade cooling water level measurement means 42.

[0033] 2 collects data from the sensors and control devices from the output section of the PLC 22 and transfers it to the cloud or a central system. This corresponds to a cutter drainage-related device side data communication means 44 that communicates data with the cutter drainage management server (described later).

[0034] In this embodiment 1, the gateway terminal 43 transmits data, including the blade cooling water flow rate measured by the blade cooling water flow rate measuring means 40, the cutter drainage flow rate measured by the cutter drainage flow rate measuring means 41, and the blade cooling water level measured by the blade cooling water level measuring means, to the cutter drainage management server via the communication network N.

[0035] FIG. 4 shows the functional configuration of the cutter wastewater management server 2 according to the first embodiment. The cutter drainage management server 2 is configured with a control unit 51, an operation unit 52, a display unit 53, a communication unit 54, a RAM 55, a memory unit 56, a calculation unit 57, etc., and each unit is connected by a bus 58.

[0036] The control unit 51 is composed of a CPU (Central Processing Unit) and the like, and comprehensively controls the processing operations of each unit of the cutter drainage management server 2. Specifically, the CPU reads out various processing programs stored in the memory unit 56 in response to an operation signal input from the operation unit 52 or an instruction signal received by the communication unit 54, expands them in the RAM 55, and performs various processes in cooperation with the programs.

[0037] The operation unit 52 is configured with a keyboard equipped with cursor keys, numeric input keys, and various function keys, etc., and a pointing device such as a mouse, and outputs operation signals input by key operations on the keyboard or mouse operations to the control unit 51.

[0038] The display unit 53 is configured to include a monitor such as an LCD (Liquid Crystal Display), and displays various screens according to instructions of a display signal input from the control unit 51.

[0039] The communication unit 54 is configured by a network interface or the like, and transmits and receives data to and from external devices connected via a communication network N such as a LAN (Local Area Network), a WAN (Wide Area Network), or the Internet. In the present invention, the communication unit 54 corresponds to the server-side data communication means 50, and exchanges data with the gateway terminal 43 of the cutter drainage-related device 11 described above.

[0040] The RAM 55 forms a work area for temporarily storing various programs read from the storage unit 56, input or output data, parameters, etc., during various processes executed and controlled by the control unit 51.

[0041] The memory unit 56 is configured with an HDD (Hard Disk Drive), a semiconductor non-volatile memory, etc., and stores various processing programs, parameters and files required to execute the programs, etc. The memory unit 56 also stores the flow rate of blade cooling water sent from multiple pavement cutting work sites (see Figure 1), the flow rate of cutter wastewater, the level of blade cooling water, the cutter wastewater recovery rate calculated by the calculation unit 57, etc., in association with the date and time, the name of the work site, etc.

[0042] The above-described functional configuration configures a cutter wastewater recovery rate calculation means 69 within the cutter wastewater management server 2. The cutter wastewater recovery rate calculation means 69 calculates the cutter wastewater recovery rate from the blade cooling water flow rate and the cutter wastewater flow rate.

[0043] (System Operation) Next, the operation of the cutter drainage remote management system 10 according to the first embodiment will be described. 6 is a flowchart showing the remote management of cutter drainage performed by the cutter drainage-related device 11 and the cutter drainage management server 2. This process is executed when pavement cutting work is performed by the cutting machine 4 at the pavement cutting work site (see FIG. 1).

[0044] First, the cutter drainage-related device 11 (see FIG. 2) determines whether the power is turned on (step 1). When the power is turned on, the gateway terminal 43 transmits the information to the cutter drainage management server 2 (step 2). The cutter drainage management server 2 certifies that the power has been turned on, along with related information such as the site name, date and time, and person in charge (step 3).

[0045] The cutter drainage-related device 11 determines whether the cutting machine 4 has started (step 4). If it is determined that the cutting machine 4 has started, the blade cooling water flow rate Qb (liters / minute), the cutter drainage flow rate Qc (liters / minute), and the blade cooling water level Hb (centimeters) are measured (step 5). Specifically, the two flow rate sensors 21 and the PLC 22 shown in FIG. 2 work together to measure the blade cooling water flow rate Qb and the cutter drainage flow rate Qc. Furthermore, the liquid level sensor 25 and the PLC 22 work together to measure the blade cooling water level Hb.

[0046] Next, the measured data of the blade cooling water flow rate Qb, cutter drainage water flow rate Qc, and blade cooling water level Hb are transmitted by the gateway terminal 43 to the cutter drainage water management server 2 via the communication network N (S6).

[0047] The cutter drainage management server 2 authenticates the cutting work performed by the cutting machine (step 7). Next, the cutter drainage management server 2 calculates the recovery rate Rr (cutter drainage flow rate Qc / blade cooling water flow rate Qb) (step 8). In this case, since both flow rates have the property of pulsating and fluctuating over time, the average flow rate after measurement for a predetermined period of time is used for the calculation.

[0048] The cutter drainage management items are displayed on the cutter drainage management server 2 (step 9). Figure 5 shows an example of a display on the cutter drainage management item display means 60, which shows the display contents on the monitor 61 and its screen 62 used as the display unit 53 (see Figure 4) of the cutter drainage management server 2.

[0049] Specifically, the screen 62 of the monitor 61 displays the site name 63, date and time 64, and person in charge 65. It also displays the blade cooling water flow rate and cutter drainage water flow rate 66. These flow rates are displayed numerically, and the flow rates that change over time can be displayed using a bar graph or line graph, for example. The calculated cutter water drain recovery rate 67 is displayed numerically and graphically, and the blade cooling water level 68 is displayed numerically and graphically.

[0050] In this way, the cutter drainage management server 2 according to the first embodiment allows the centralized control center to remotely monitor the operating status of the cutter drainage-related devices 11 at multiple pavement cutting work sites (see FIG. 1) using the monitor 61. Furthermore, the centralized control center can remotely monitor the remaining amount of blade cooling water, so that a blade cooling water transport vehicle can be dispatched in a timely manner to replenish blade cooling water at pavement cutting work sites where the remaining amount of blade cooling water is low.

[0051] Next, the cutter drainage management server 2 stores the cutter drainage management items in the memory unit 56 (step 10). The cutter drainage management items stored in the memory unit 56 can be read out later as needed. This data can accurately certify the amount of cutter drainage collected at each pavement cutting work site, the cutter drainage collection rate, and other figures, and can be used as useful data for various procedures at related organizations.

[0052] The cutter drainage-related device 11 determines whether the cutting machine 4 has stopped (step 11). If it is determined that the cutting machine 4 has not stopped, the process returns to step 5, where measurement of the cutter drainage management items continues and remote management continues. On the other hand, if it is determined that the cutting machine 4 has stopped, it determines whether the cutter drainage-related device 3 has been powered off (S12).

[0053] If it is determined that the power has not been turned off, remote management continues. If it is determined that the power has been turned off, the cutter drainage-related device 3 transmits a message to the cutter drainage management server 2 that the power has been turned off (S13). This causes the operation of the cutter drainage-related device 3 to end (S14).

[0054] The cutter drainage management server 2 authenticates that the cutter drainage-related device 3 has been powered off (step 15), and then ends the remote management by the cutter drainage management server 2 (step 16).

[0055] Second Embodiment (System configuration) Figure 7 shows the system configuration of a cutter drainage remote management system 80 according to the second embodiment. The configuration of a cutter drainage-related device 83 according to the second embodiment has additional and modified components compared to the cutter drainage-related device 11 (see Figure 2) according to the first embodiment. Below, based on Figure 7, only the additional and modified components will be described in detail, and a description of the common components will be omitted.

[0056] The cutter drainage-related device 83 has an on-board dewatering machine 81 mounted on the vehicle 12 instead of the blade cooling water tank 13 and cutter drainage water storage tank 18 according to the first embodiment. The on-board dewatering machine 81 is equipped with cutter drainage recycling means 85 for recycling cutter drainage. The cutter drainage recycling means 85 separates the cutter drainage into treated water and solids, and reuses the treated water as blade cooling water.

[0057] The on-board dehydration processor 81 is equipped with a water tank (not shown) that corresponds to the blade cooling water tank and cutter wastewater storage tank according to the first embodiment. In the on-board dehydration processor 81, a flocculant is added to the collected cutter wastewater and the water is stirred. Furthermore, a diaphragm pump (not shown) driven by a generator (not shown) mounted on the on-board dehydration processor 81 sends the cutter wastewater toward a filter chamber 84 where it is filtered. Then, solid matter such as cutting powder contained in the cutter wastewater is separated in the filter chamber 84, and treated water is produced.

[0058] As shown in Fig. 7, a blade cooling water tank (not shown) of an on-board dehydration processor 81 mounted on a vehicle 12 is connected to the cutting machine 4 by a blade cooling water supply pipe 14. Blade cooling water 15 in the blade cooling water tank is sent to the blade 16 of the cutting machine 4 through the blade cooling water supply pipe 14. The arrows in the figure indicate the direction in which the blade cooling water 15 flows.

[0059] The cutting machine 4 and a cutter wastewater storage tank (not shown) of the on-board dewatering treatment machine 81 mounted on the vehicle 12 are connected by a cutter wastewater recovery pipe 19. Cutter wastewater 20 collected by the cutter wastewater suction function of the cutting machine 4 passes through the cutter wastewater recovery pipe 19 and is stored in the cutter wastewater storage tank (not shown) of the on-board dewatering treatment machine 81.

[0060] (System Operation) The operation of the cutter drainage remote management system 80 according to the second embodiment is common to the operation of the cutter drainage remote management system 10 according to the first embodiment shown in Fig. 6. Therefore, the cutter drainage remote management system 80 according to the second embodiment can achieve the same functions and effects as the cutter drainage remote management system 10 according to the first embodiment.

[0061] In the cutter wastewater remote management system 80 according to the second embodiment, the cutter wastewater is further reused by the above-mentioned cutter wastewater recycling means 85. That is, the collected cutter wastewater is filtered and dewatered in the filter chamber 84 to separate it into treated water and solids.

[0062] As described above, the cutter wastewater remote management system 80 according to the second embodiment allows the cutter wastewater to be reused by the cutter wastewater recycling means 85 of the vehicle-mounted dewatering machine 81. This significantly extends the time between dispatches for additional replenishment of blade cooling water. In addition, there is no longer a need to take the collected cutter wastewater to a treatment facility for treatment, thereby reducing the time and cost required for this.

[0063] Third Embodiment (System configuration) Figure 8 shows the system configuration of a cutter drainage remote management system 90 according to the third embodiment. The configuration of a cutter drainage-related device 91 according to the third embodiment has additional components compared to the cutter drainage-related device 11 (see Figure 2) according to the first embodiment. Only the additional components will be described in detail below with reference to Figure 8, and a description of the common components will be omitted. In addition, the system configuration of the cutter drainage remote management system 90 according to the third embodiment can also be implemented by providing the same additional configuration as the cutter drainage-related device 83 according to the second embodiment (see Figure 7).

[0064] As shown in Figure 8, a metal detector 92 is installed in the cutting machine 4. The metal detector 92 uses an electromagnetic induction method in which a current is passed through a coil to detect metal by the distortion of the electric field. The metal detector 92 and the PLC 22 are connected by a signal line 93. The metal detector 92 and the PLC 22 constitute buried metal object detection means 94.

[0065] 8, the cutting machine 4 is further provided with a rotating light (Patlite (registered trademark)) 95. The rotating light 95 and the PLC 22 are connected by a signal line 96. The rotating light 95 and the PLC 22 constitute an alarm means 97. In the above description, the metal detector 92 and rotating light 95, which are additional components, are connected to the PLC 22 via signal lines 93 and 96, i.e., a wired embodiment is described. However, it goes without saying that the metal detector 92 and rotating light 95 may be connected to the PLC 22 wirelessly. In this case, a transceiver and a power source for the metal detector 92 and rotating light 95 are mounted on the cutting machine 4.

[0066] (System Operation) Next, the operation of the cutter drainage remote management system 90 according to the third embodiment will be described. FIG. 9 is a flowchart showing the remote management of cutter drainage executed by the cutter drainage-related device 91 and the cutter drainage management server 2 according to the third embodiment.

[0067] The flowchart of Fig. 9 for the cutter drainage remote management system 90 according to the third embodiment is the same as the flowchart of the cutter drainage remote management system 10 according to the first embodiment (see Fig. 6), except that a flowchart for part A located approximately in the center has been added. Below, only the added control will be described in detail based on Fig. 10 showing the flowchart for part A. Explanations of common parts will be omitted.

[0068] As shown in FIG. 10, buried metal objects 98 are detected by a metal detector 92 (buried metal object detection means 94) (step 20). Specific buried metal objects include water and sewerage pipes, optical fiber joint boxes (registered trademark), various communication cables, and power lines. A warning (alarm) is issued by a rotating light 95 (alarm means 97) in the cutter drainage-related device 91 (step 21). This alerts the operator of the cutting machine 4 that if the pavement cutting operation continues, the blade may cut the buried metal objects, and the operator stops the cutting operation. In this way, a serious cutting accident is prevented.

[0069] The detection data is sent to the cutter drainage management server 2 (step 22). In the cutter drainage management server 2, the cutter drainage management item display means 60 (monitor 61) displays (alarms) that a buried metal object has been detected (step 23). This allows the management center to urgently notify the owner of the presence of a buried metal object and promptly discuss how to deal with the situation with the owner. In addition, the memory unit 56 (see Figure 4) stores the fact that a buried metal object has been detected (step 24).

[0070] As described above, the cutter drainage remote management system 90 according to the third aspect of the present invention can prevent the cutting of buried metal objects. Therefore, by preventing damage to valuable infrastructure facilities, long-term work interruptions can be eliminated and the efficiency of the entire pavement cutting work can be improved.

[0071] 10, in the cutter drainage remote management system 90 according to the third invention, the cutter drainage management server 2 also stores the cutter drainage management items and the detection of buried metal objects in the memory unit 56 (step 24). The cutter drainage management items and buried metal object detection information stored in the memory unit 56 can be read out as needed at a later date. In this way, since it can be certified as data for each pavement cutting work site, it can be used as data for procedures at a later date by related organizations.

[0072] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is defined by the appended claims. [Explanation of symbols]
