Description

  The present invention relates to a system and method for collecting data generated by a remote machine at a work site or data center at a work site where the available communication lines are limited.

  As background art, there is Japanese Patent No. 5147823 (Patent Document 1). In this gazette, in order to collect data generated by a remote machine that does not have a fixed communication line at the site base, a transport vehicle that reciprocates between the machine and the site base from the server at the site base And the task list with the data to be collected is received by wireless communication, moved from the site to the work site of the machine to be collected, collected from the machine to be collected by wireless communication, moved to the site, and collected. A system is disclosed in which such data is transmitted by wireless communication to a server at a site.

  Further, in the system disclosed in Patent Document 1, when there are a plurality of the above-described transport vehicles, the base is configured so that the machine preferentially transmits data to the transport vehicles that reciprocate between the machine and the site base frequently. A configuration is also included in which the server delivers a transport vehicle list indicating the priority of data transmission to the transport vehicle.

Japanese Patent No. 5147823

  In the system disclosed in Patent Document 1, it is shown that data collection efficiency is improved by setting the priority of a transport vehicle that collects data from a machine.

  By the way, the data generated by the machine includes daily report data, which is a summary of the daily operating status of the machine, sensor data output by sensors installed in the machine, and alarm data indicating the error status of each part of the machine body. There are various types depending on the business, such as communication error logs including communication failure information. Among them, for example, alarm data and a communication error log need to be collected as soon as possible in order to quickly detect a failure such as a machine failure or a stoppage of the collection system, and to perform preventive maintenance and recovery. On the other hand, daily report data and sensor data are rarely required to have real-time collection time.

  As described above, although the data generated by the machine has an attribute called collection priority, in the system disclosed in Patent Document 1, all the data is transferred to the site on the site regardless of the data collection priority. It is collected at the time of arrival. That is, Patent Document 1 does not consider collecting data with a high collection priority as soon as possible when collecting data generated by a remote machine without a fixed communication line.

  In order to solve the above problems, a wireless relay transfer apparatus according to the present invention is installed in an area where communication with a first apparatus connected to a data center via an Internet line is impossible via a mobile phone line. A first wireless communication unit that is installed in a moving body that moves between the first and second devices and transmits / receives data to / from the data center via the mobile phone communication line; and the first and second devices. A second wireless communication unit that transmits and receives data via a distance wireless communication line, a data storage unit that stores data received from the first and second devices, and communication by the mobile phone are possible An analysis unit that detects movement to an area, and the first wireless communication unit, when the analysis unit detects the movement, includes a predetermined data in the data received from the second wireless communication device. Data before The second wireless communication unit transmits the received data other than the predetermined data to the first data center via the short-range wireless communication line via a mobile phone line. Send to.

  In the wireless relay transfer method according to the present invention, the first device connected to the data center via the Internet line and the second device installed in the area where communication via the mobile phone line is impossible. When the wireless relay transfer device installed in the moving body that moves between the two devices detects that it has moved to an area where communication by the mobile phone is possible, the data received from the second device via the short-range wireless line Is transmitted to the data center via the mobile phone line, and the received data other than the predetermined data is transmitted to the first device via the short-range wireless communication line. Send to.

  According to the present invention, in a work site where the available communication line is limited, it becomes possible to collect data with high collection priority in business among data generated by a remote machine as soon as possible. By collecting less frequent data by an inexpensive data transmission means, the cost of data collection can be reduced.

  In addition, by collecting data with high collection priority, such as machine alarm data and communication error logs, as soon as possible, it is possible to respond quickly to machine body failures and data collection system failures. It is possible to reduce the downtime and maintenance cost of the collection system.

The thing shown with the same number with respect to several figures shall have the same function. In the present embodiment, the present invention can be applied to all data communication between devices in a work site where available communication lines are limited. However, in the following description, data communication between a mining machine and a base server in a mine work site will be described as an example. To do.

  As a first embodiment of the present invention, a machine information collection system and a machine information collection method in the case where there is one transport vehicle that moves between a site base and a mining machine and transports the mined mineral will be described.

  FIG. 1 is a schematic diagram of the entire machine information collection system in the first embodiment. In addition to explaining the components of the machine information collection system in the present embodiment using this figure, a transport vehicle and movement of machine information are shown. The machine information collection method will be described according to S1070 to S1077.

  The mine site 1000 is a work site where communication lines that can be used for reasons such as topography and installation costs are limited, such as mountainous areas. In the present embodiment, although the 3G line 1001 can be used in a part of the mine site as an example of the mobile communication line, there is an area 1002 incapable of 3G communication for reasons such as topography and installation costs such as the vicinity of the mining site. Suppose that it is an existing work site.

  Within the mine site 1000, a work machine 1030 that performs mining at a mining site included in a site server 1010, 3G communication impossible area 1002 installed in a site office, a processing site of a mining mineral, a parking lot of a transport vehicle described later, A transport vehicle 1020 that moves between the base server 1010 and the work machine 1030 to transport the mining mineral (1020A to 1020E in the figure are all the same transport vehicle 1020, but for convenience of explanation, depending on the position and the state. Is changing).

  In the machine information collection system of the present embodiment, it is assumed that the machine information is stored in the data center 1004 located far from the mine site 1000. The machine information stored in the data center 1004 is used for operations such as fault detection and recovery, and preventive maintenance.

  Before moving to the mining site, the transport vehicle 1020A shows the state of the transport vehicle at the time of receiving a task necessary for collecting machine information from the base server 1010, and when the transport vehicle 1020B arrives at the work machine 1030 at the mining site. The transport vehicle 1020C shows the state of the transport vehicle at the time when the loading of the mining minerals and the collection of the data generated by the work machine 1030 are completed, and the transport vehicle 1020D moves from the mining site to the base server 1010. The state of the transport vehicle at the time of leaving the 3G communication disabled area 1002 is shown, and the transport vehicle 1020E indicates the state of the transport vehicle at the time of arrival at the base server 1010.

  Although the detailed configuration will be described later, the base server 1010 has a task list 1011 for indicating a task of collecting machine information to the transport vehicle 1020 and the work machine 1030, a location such as a road, a base, and a machine in the mine site 1000, and an area where 3G communication is possible Is generated and stored, and the task list 1011 and the communication area map 1012 are transmitted to the transport vehicle 1020 (1020A) by the wireless communication unit 1040 such as a Wi-Fi module (S1070).

  Although the detailed configuration will be described later, the transport vehicle 1020 includes a wireless communication unit 1040, a 3G communication unit 1050, and a positioning unit 1060 such as a GPS (Global Positioning System), and receives a task list 1011 and a communication area map 1012 from the base server 1010. Are accumulated (S1070).

  The transport vehicle 1020 moves to the mining site shown in the communication area map 1012, automatically recognizes the work machine 1030 as the collection target machine using the wireless communication unit 1040 based on the task list 1011, and transmits the task list 1011 (S1071). . For example, the technology described in Patent Document 1 can be used for automatic recognition of a collection target machine and establishment of communication processing.

  Although a detailed configuration will be described later, the work machine 1030 includes a wireless communication unit 1040 and generates machine information associated with the mining work. The machine information is classified into machine information 1031 having a high collection priority and machine information 1032 having a low collection priority, and the difference in priority is set in advance for each machine information. Assume that sharing with the base server 1010 in the process of introducing 1030 is also possible.

  The work machine 1030 transmits machine information 1031 and 1032 according to the task list 1011 received from the transport vehicle 1020 (1020B) to the transport vehicle 1020 (1020C) using the wireless communication unit 1040 (S1072). The transport vehicle 1020C accumulates the machine information 1031 and 1032 received from the work machine 1030, and moves in the 3G communication disabled area 1002 from the mining site to the base server 1010 (S1073).

  If it is determined that the transport vehicle 1020 has left the 3G communication disabled area 1002 while moving to the base server 1010, the transport vehicle 1020 transmits only the machine information 1031 having a high collection priority to the data center 1004 using the 3G communication unit 1050 (S1074). ). In addition, after transmitting to the base server 1010 using the 3G communication unit 1050, the base server 1010 may transmit to the data center 1004 through the Internet line 1003.

  The transport vehicle 1020D moves to the base server 1010 (S1075). At this time, the machine information stored in the transport vehicle 1020D is only the machine information 1032 having a low collection priority. When the transport vehicle 1020E arrives at the base server 1010, it uses the wireless communication unit 1040 to transmit machine information 1032 having a low collection priority to the base server, and the base server 1010 accumulates the received machine information 1032 (S1076). ). The base server 1010 transmits machine information 1032 having a low collection priority to the data center 1004 through the Internet line 1003 (S1077).

This information may be recorded as machine management information, which will be described later, stored in the base server 1010 in the process of installing the communication module on the collection target machine and the transport vehicle, for example.

  In addition, as information indicating machine information to be collected among a plurality of types of machine information, for example, ID information for distinguishing machine information is included. This information is set in the machine information generation unit in the process of installing a machine information generation unit (to be described later) of the collection target machine, for example, and the set ID information is accumulated in the base server 1010.

  FIG. 5 is a sequence diagram of a machine information collection flow in the first embodiment. In S1070 to S1077 in FIG. 1, the machine information collection method has been described by showing the movement of setting data, machine information, and component elements. However, in this drawing, the machine information collection method is described by the sequence of the processing flow of each component element. To do.

  The base server 1010 is operated as necessary by the mining operation manager, the transport vehicle 1020 is moved between the base and the mining site by the driver, and the work machine 1030 is operated by the worker to perform the mining work. Suppose you do. It is assumed that the transport vehicle 1020 is waiting in the vicinity of the base server 1010 at the start of the shift of the work of transporting the mining mineral to the base (S500).

  In addition, the work machine 1030 performs a mining operation in the mining area, and accordingly, machine information is generated in the machine information generation unit 43 and stored as generated machine information 441 in the data storage unit 44 (S501).

  At the site, the mining operation manager operates the processing input unit 25 of the site server 1010, selects the work machine to be collected and the machine information to be collected from the machine management information 242, and sets the collection priority setting 241 as Among the machine information, the one having a high collection priority is set, the information on the transport vehicle collecting the machine information is selected from the machine management information 242, and the task list generation unit 21 generates the task list 1011 based on the information. The data is stored in the data storage unit 24 (S502).

  Next, at the site, the mining operation manager operates the processing input unit 25 of the site server 1010, and the communication area map generation unit 22 generates the communication area map 1012 based on the mesh map data 244 and the communication speed measurement data 245, and stores the data. The data is stored in the unit 24 (S503). This process may be performed periodically regardless of the process of the mine business manager, or the generated communication area map may be reused.

  Next, at the site, the mine operation manager operates the processing input unit 25 of the site server 1010 and transmits the task list 1011 and the communication area map 1012 to the transport vehicle 1020 waiting at the site using the wireless communication unit 1040. The transport vehicle 1020 receives the task list 1011 and the communication area map 1012 using the wireless communication unit 1040, and stores them in the data storage unit 34 (S504, S505). This processing may be performed automatically between the base server 1010 and the transport vehicle 1020 without depending on the processing of the mining business manager.

  Next, when it is detected in the transport vehicle 1020 that the task list 1011 has been accumulated, the task list analysis unit 31 analyzes the task list 1011 to analyze the position information and IP address of the collection target machine, and the ID of the machine information to be collected. Or, the ID of the machine information having a high collection priority is extracted, the collection priority information is transmitted to the priority transmission determination unit 33, and the information of the collection target machine is transmitted to, for example, the video display device viewed by the driver. Send. When it is detected that the communication area map 1012 is accumulated, the communication area map analysis unit 32 analyzes the communication area map 1012 and extracts communication speed information for the position information (S506). The analysis of the communication area map 1012 only needs to be completed before the machine information is received from the work machine 1030 in S512 described later.

  Next, when the information on the collection target machine is displayed on the video display device, for example, the driver of the transport vehicle 1020 drives the transport vehicle 1020 from the base to the mining site accordingly (S507).

  Next, when the transport vehicle 1020 arrives at the mining site, the transport vehicle 1020 automatically recognizes the work machine 1030 that is the collection target machine obtained from the task list 1011, and uses the wireless communication unit 1040 for the task list 1011. The work machine 1030 receives the task list 1011 using the wireless communication unit 1040 and stores it in the data storage unit 44 (S508, S509).

  Next, when it is detected in the work machine 1030 that the task list 1011 is accumulated, the task list analysis unit 41 analyzes the task list 1011 and extracts the IP address of the transport vehicle and the ID of the machine information to be collected, The machine information ID to be collected is transmitted to the collection target setting unit 42 (S510).

  Next, in the work machine 1030, when the collection target setting unit 42 receives the ID group of the machine information to be collected, the machine information to be collected from the generated machine information 441 accumulated in the data accumulation unit 44 ( For example, 1031 and 1032) are transmitted to the transport vehicle 1020 using the wireless communication unit 1040, and the transport vehicle 1020 receives the machine information using the wireless communication unit 1040 and stores the machine information in the data storage unit 34 (S511, S512). ). At this time, for example, the video display device viewed by the driver may be notified that the data reception is completed. S509 to S512 are automatically performed while the mining mineral of the work machine 1030 is loaded on the transport vehicle 1020.

  Next, when the notification of data reception completion is displayed on the video display device, for example, the driver of the transport vehicle 1020 drives toward the base in order to transport the mined mineral to the base. At this time, the communication area map analysis unit 32 acquires the position information of the transport vehicle 1020 using the positioning unit 1060, and periodically acquires the 3G communication speed information for the position information from the analysis result of the communication area map 1012. repeat. If it is detected that the 3G communication impossible area 1002 has been left in the middle of movement, the information is transmitted to the priority transmission determination unit 33, and when the priority transmission determination unit 33 receives the information, the collection priority extracted from the task list 1011 Among the collected machine information 341 stored in the data storage unit 34, the machine information 1031 having a high collection priority is transmitted to the data center 1004 by using the 3G communication unit 1050 based on the ID of the machine information having a high level. (S513, S514).

Here, the criterion for determining that the 3G communication disabled area 1002 has come out is to set threshold information in the communication area map 1012 in advance, and the threshold information is the machine information to be preferentially collected for business reasons. Set based on the data size. This setting includes, for example, the data size as an attribute of the machine information included in the machine management information 242, and when an ID of machine information having a high collection priority is selected in the collection priority setting 241 of the base server 1010, the machine information The data size included in the machine information included in the management information 242 may be acquired.
The driver of the transport vehicle 1020 may drive to the base without being aware of the processing of S513 and S514 (S515).

  Next, when the transport vehicle 1020 arrives at the site, the transport vehicle 1020 automatically recognizes the site server 1010 (the site server 1010 may automatically recognize the transport vehicle 1020), and transmits in S514 using the wireless communication unit 1040. The collected machine information (for example, machine information 1032 having a low collection priority) stored in the data storage unit 34 is transmitted to the base server 1010, and the base server 1010 uses the wireless communication unit 1040 to store the machine information. It is received and stored in the data storage unit 24 (S516, S517). Thereafter, the base server 1010 transmits the machine information to the data center 1004 using the Internet communication unit 23.

  As described above, machine information with high collection priority can be collected as soon as possible among machine information. At the same time, machine information with low collection priority can be collected by transporting by vehicle, wireless communication and Internet communication. It is also possible to reduce the communication cost of the entire information collection system.

  There is a possibility that the area where 3G communication is possible and the area where 3G communication is impossible are repeated, so that it may arrive at the base server 1010 before all the machine information with a high collection priority is transmitted. However, the effect is still sufficient. Further, the transport vehicle 1020 is not limited to the collection priority, and may be configured to transmit all the machine information remaining in the data storage unit 34 to the base server 1010.

  The communication area map 1012 may be a binary value of “3G communication is possible” or “3G communication is not possible”, or may be a multi-value based on the communication speed. In the case of multi-value, it is possible to set multi-level collection priorities corresponding to the multi-value, and a collection method of transmitting only the highest-priority machine information only in an area where 3G communication is possible even a little is possible.

  The communication area map 1012 is used to determine the 3G communication disabled area 1002, but instead of using the communication area map 1012, the 3G communication unit 1050 moves while measuring the communication speed periodically to recognize the communication area. Also good. However, in that case, the time cost and power consumption cost for the determination increase, such as an increase in the number of communication retries in the communication disabled area.

  Machine information generated by the transport vehicle 1020 itself can also be collected by a similar machine information collection system and machine information collection method. In that case, the collection target and the collection priority setting for the machine information generated by the transport vehicle 1020 may be added to the task list 1011. The priority transmission determination unit 33 of the transport vehicle 1020 is generated by the transport vehicle 1020 itself. The machine information stored in the data storage unit 34 may be transmitted using the 3G communication unit 1050 in accordance with the collection priority.

  As a second embodiment of the present invention, only a portion different from the first embodiment will be described regarding a machine information collection system and a machine information collection method to which processing for updating the communication area map 1012 in the first embodiment is added.

  FIG. 6 is a schematic diagram of the entire machine information collection system in the second embodiment. The difference from the schematic diagram of the entire machine information collection system in the first embodiment described in FIG. 1 is that a 3G communication log 6013 including information on the communication speed of 3G communication is generated and accumulated while the transport vehicle 6020 is moving, After the transport vehicle 6020 returns to the base, the 3G communication log 6013 is transmitted to the base server 6010 together with the machine information (S6078). As will be described later with reference to FIG. 9, by determining the communication area map 1012 based on the 3G communication log 6013 accumulated in the base server 6010, the determination accuracy of the 3G non-communication area 1002 that changes according to the change in the terrain of the mine. Can be improved.

  FIG. 7 is a block diagram of the base server in the second embodiment. The difference from the block diagram of the base server in the first embodiment described in FIG. 2 is that the 3G communication log 6013 is stored in the data storage unit 24, and the communication area map generation unit 22 is different from the communication area map generation update unit 72. It is to become. The communication area map generation update unit 72 is configured as a program in which a process for updating the communication speed measurement data 245 based on the 3G communication log 6013 is added in the communication area map generation process in the communication area map generation unit 22. The 3G communication log 6013 is data obtained by linking position information and 3G communication speed, and is generated by a 3G communication speed measurement unit described later.

  FIG. 8 is a block diagram of the transport vehicle in the second embodiment. The difference from the block diagram of the transport vehicle in the first embodiment described in FIG. 3 is that the 3G communication log 6013 is stored in the data storage unit 34 and the 3G communication speed measurement unit 85 is added. . For example, the 3G communication speed measurement unit 85 periodically transmits test data from the 3G communication unit 1050 and combines the result of measuring the communication speed with the position information acquired from the positioning unit 1060 to generate the 3G communication log 6013. The program is stored in the data storage unit 34. In the 3G communication log 6013, the position information and the measurement result may be added every time the communication speed is measured.

  FIG. 9 is a sequence diagram of a machine information collection flow in the second embodiment. The difference from the sequence diagram of the machine information collection flow in the first embodiment described in FIG. 5 is that the 3G communication log 6013 is collected and accumulated when the transport vehicle 6020 moves (S907, S913, S915) and the transport The vehicle 6020 returns from the mining site to the base, transmits the 3G communication log 6013 to the base server 6010 (S918, S919), and communicates by the communication area map generation update unit 72 based on the 3G communication log 6013 received by the base server 6010. The area map is updated (S920).

  The communication area map update process described in this embodiment can be similarly applied to all the embodiments described later.

Only the parts different from the form will be described.

  Although the system of the first embodiment, which is a machine information collection system and a machine information collection method in the case of one transport vehicle, can be applied to all the transport vehicles, all the transport vehicles follow the same road. However, depending on the transport vehicle, it may not be easy to enter the 3G communicable area, and as a result, the collection of machine information with a high collection priority may be delayed.

  FIG. 10 is a schematic diagram of the entire machine information collection system in the third embodiment. The difference from the schematic diagram of the entire machine information collection system in the first embodiment described with reference to FIG. 1 is that the base server 10010 generates a task list 10011 based on the operation plan 10014 and shows this as an example of a plurality of transport vehicles. The work vehicle 10020 is transmitted to the transport vehicle 1020A and the transport vehicle 10080A (S1070, S10070), and the work machine 10030 analyzes the task list 10011 received from the transport vehicle 1020 and determines that the transport vehicle 1020 is a transport vehicle to which machine information should be transmitted. And sending machine information. Since the transport vehicle 10080 leaves the 3G communication disabled area 1002 later than the transport vehicle 1020 (S10071, S10073), the work machine 10030 does not transmit machine information to the transport vehicle 10080.

  As will be described later with reference to FIG. 13, by generating a task list 10011 to which a vehicle that exits from the 3G communication disabled area 1002 earliest is set as a machine information transmission target vehicle, a task list 10011 is generated. The work machine 10030 can determine the transport vehicle that can transmit the machine information with the highest collection priority first, and the collection speed of the machine information with the high collection priority can be improved.

  FIG. 11 is a block diagram of the base server in the third embodiment. The difference from the block diagram of the base server in the first embodiment described in FIG. 2 is that the operation plan 10014 is stored in the data storage unit 24 and the processing of the task list generation unit 111 is a task as described later. This is partly different from the list generation unit 22.

  In the task list generation process in the task list generation unit 22, the task list generation unit 111 adds a setting that sets the transport vehicle that exits the 3G communication disabled area 1002 as the machine information transmission target transport vehicle earliest based on the operation plan 10014. The task list 10011 is configured as a program with added processing. The machine information transmission target transport vehicle is set as an IP address of the transport vehicle, for example.

  The operation plan 10014 is a list of departures, passages, arrival times, driving routes, drivers, and the like between the base and the work machine, for example, for each of a plurality of transport vehicles. sign up. Based on the speed performance information of each transport vehicle included in the operation plan 10014 and the machine management information 242 and the past driving history of the driver, position information of the transport vehicle for each hour is estimated and matched with the communication area map 1012. Thus, it is possible to estimate the transport vehicle that comes out of the 3G communication disabled area 1002 earliest.

  FIG. 12 is a block diagram of a work machine according to the third embodiment. A difference from the block diagram of the work machine in the first embodiment described in FIG. 4 is that the target transport vehicle determination unit 125 is provided. The target transport vehicle determination unit 125 receives the information of the machine information transmission target transport vehicle extracted from the task list 10011 by the task list analysis unit 41 with respect to the transport vehicle that has transmitted the task list 10011. If it is a transmission target transport vehicle, it is configured as a program that instructs the collection target setting unit 42 to transmit the collection target machine information described in the task list 10011 to the transport vehicle.

  FIG. 13 is a sequence diagram of a machine information collection flow in the third embodiment. The difference from the sequence diagram of the machine information collection flow in the first embodiment described with reference to FIG. 5 is that the base server 10010 transports the transport vehicle 1020 to the machine information transmission target based on the operation plan for the transport vehicle 1020 and the transport vehicle 10080. Generate the task list 10011 to which the setting as a car is added (S1302), and the work machine 10030 analyzes the task list 10011 and transmits the machine information to the transport vehicle 1020 determined to be the transport target transport vehicle. The machine information is not transmitted to the transport vehicle 10080 determined not to be the machine information transmission target transport vehicle (S1310).

  As a fourth embodiment of the present invention, a machine information collection system and a machine information collection method to which a function of transferring machine information between a plurality of transport vehicles in the third embodiment is added. I will explain only.

  FIG. 14 is a schematic diagram of a part of the machine information collection system according to the fourth embodiment. Only the configuration in the vicinity of the mining site, which is different from the third embodiment, is shown. Of the two transport vehicles 14020 and the transport vehicle 14080, the transport vehicle 14020 is assumed to be a transport vehicle targeted for machine information transmission.

  The work machine 14030 generates a transport vehicle passage history 1433 that is history information of the transport vehicle group that has moved from the base to the work machine 14030, and the latest transport vehicle together with the machine information 1031 and 1032 is stored in the transport information target transport vehicle 14020. The passage history 1433 is transmitted (S14070). The transport vehicle passage history 1433 is log data that describes, for example, an IP address and a transit time for identifying a transport vehicle that has exchanged mining and machine information from the work machine 14030. Assume that the information is added to the machine 14030 and is added every time the vehicle is exchanged.

  The transport vehicle 14020 (14020C) that has received the machine information 1031 and 1032 and the transport vehicle passage history 1433 is moving to the base, and the transport vehicle 14020 based on the transport vehicle passage history 1433 before leaving the 3G communication disabled area 1002. First, a transport vehicle (referred to as a transport vehicle 14080 in this embodiment) that is expected to exit the 3G communication disabled area 1002 is searched, and machine information transfer to the transport vehicle 14080 is attempted using the wireless communication unit. For example, the transport vehicle 14080 that has passed immediately before is specified, and machine information transfer to the transport vehicle 14080 is attempted. This information transfer can be performed by the existing ad hoc communication technology between the wireless communication units. When the transport vehicle 14080 is found in the wireless communicable range, the machine information 1031 having a high collection priority is transferred to the transport vehicle 14080. (S14071).

  Upon receiving the machine information, the transport vehicle 14080 transmits the machine information using the 3G communication unit when leaving the 3G communication disabled area 1002. If not found, the machine information 1031 having a high collection priority is transmitted using the 3G communication unit after moving until it leaves the 3G communication impossible area 1002 as in the above-described embodiment.

  As described above, after receiving the machine information from the work machine 14030, the transport vehicle 14020 can transmit the machine information 1031 having a high collection priority earlier than the method of leaving the 3G communication disabled area 1002 only by the movement of the driver. Become.

  FIG. 15 is a block diagram of a transport vehicle according to the fourth embodiment. The difference from the block diagram of the transport vehicle in the first embodiment described in FIG. 3 (the same applies to the third embodiment) is that a transfer unit 155 for transferring machine information is provided, and the data storage unit 34 has a work It is to accumulate the transport vehicle passage history 1433 received from the machine 14030.

  When the transfer unit 155 receives the machine information 341 and the transport vehicle passage history 1433, the transfer unit 155 analyzes the transport vehicle passage history 1433, refers to the communication area map 1012, and transfers that are expected to exit from the 3G communication disabled area 1002 before itself. When the destination transport vehicle is searched and the transfer destination transport vehicle is found, communication with the transfer destination transport vehicle is attempted using the wireless communication unit 1040. When communication is possible, the machine information 1031 having a high collection priority is stored. Configure as a program to transfer.

  FIG. 16 is a block diagram of a work machine according to the fourth embodiment. The difference from the block diagram of the work machine in the third embodiment described with reference to FIG. 12 is that a transport vehicle passage history generation unit 166 that generates a transport vehicle passage history is provided, and that the data storage unit 44 includes a transport vehicle passage history. It is to accumulate the transport vehicle passage history 1433 generated by the generation unit 166. When the information indicating the transport vehicle such as the IP address is notified from the task list analysis unit 41, the transport vehicle passage history generation unit 166 generates the transport vehicle pass history 1433 and stores it in the data storage unit 44. Configure as.

  In the present embodiment, an example of transferring machine information between transport vehicles has been described. However, if installation is possible, a communication device having a function of relaying wireless communication or a function of performing 3G communication is installed on a part of a moving route to carry the vehicle. It is good also as a system which performs 3G communication from a vehicle via a relay communication apparatus to another transport vehicle or from a vehicle via a relay communication apparatus. Further, the machine information transfer process described in the present embodiment can be similarly applied to all the embodiments described later.

  As a fifth embodiment of the present invention, in the third embodiment, a machine information collection system and a machine information collection method, which have a function of determining a machine information transmission target transport vehicle not only at a base server but also at a work machine, are attached. Only parts different from the third embodiment will be described.

  FIG. 17 is a schematic diagram of a part of the machine information collection system in the fifth embodiment. Only the configuration in the vicinity of the mining site, which is different from the third embodiment, is shown. Among the three transport vehicles 17020, transport vehicles 17080, and transport vehicles 17090, the transport vehicle 17020 is a transport vehicle targeted for machine information transmission determined by the base server 1010. The transport vehicle 17020 has already received the machine information 1031A and 1032A from the work machine 17030. It is assumed that the vehicle is received and accumulated and is moving toward the base (S17070), and the transport vehicle 17080 and the transport vehicle 17090 are moving from the base toward the mining site (S17071, S17072). In addition to the same configuration as that of the third embodiment, all the transport vehicles also receive and accumulate the operation plan 10014 described in the third embodiment from the base server 1010 together with the task list and the communication area map.

  The work machine 17030 is still performing mining work after transmitting the machine information 1031A and 1032A to the transport vehicle 17020, and generates machine information 1031B and 1032B for the work. In addition, the operation plan 10014 and the communication area map 1012 are received from the preceding transport vehicle (for example, the transport vehicle 17020) and accumulated. Based on the operation plan 10014, the transport vehicle passage history 1433, and the communication area map 1012, the work machine 17030 collects the machine information 1031B having a high collection priority from the transport vehicle 17080 and the transport vehicle 17090 that will come to the mining site. Then, while returning from the mining site to the base, the transport vehicle that exits the 3G non-communication area 1002 is determined earlier (S17073), and when the transport vehicle arrives at the mining site, machine information 1031B and 1032B are transmitted. As in the third embodiment, the transport vehicle that has received and accumulated the machine information 1031B and 1032B exits the 3G communication disabled area 1002 when moving to the base, and then sends the machine information 1031B having a high collection priority to the 3G communication unit. Send using.

  As a result, machine information with high collection priority can be sent to another transport vehicle without waiting for the transport vehicle determined by the base server to return to the mining site next, and collected as a whole. Machine information with high priority can be collected more quickly.

  FIG. 18 is a block diagram of a work machine according to the fifth embodiment. The difference from the block diagram of the work machine in the third embodiment described in FIG. 12 is that the target transport vehicle determination unit 185 determines the target transport vehicle to be described later in addition to the processing of the target transport vehicle determination unit 125 described above. Based on the information transmitted from the unit 187, the machine information transmission target transport vehicle is determined, the collection priority monitoring unit 186, the target transport vehicle determination unit 187, the transport vehicle passage history generation unit 166, and the communication area map. The analysis unit 188 is provided, and the operation plan 10014, the transport vehicle passage history 1433, and the communication area map 1012 are stored in the data storage unit 44. The communication area map analysis unit 188 has the same configuration as the communication area map analysis unit 32 described above.

  The collection priority monitoring unit 186 monitors the generated machine information 441 generated by the machine information generation unit 43 and stored in the data storage unit 44 along with the mining work, and machine information (1031A and 1031B) having a high collection priority. If the generation | occurrence | production of this is detected, it will comprise as a program which notifies the object transport vehicle determination part 187 mentioned later that the machine information with high collection priority was produced | generated.

  The target transport vehicle determination unit 187 receives the notification that the machine information with the high collection priority is generated from the collection priority monitoring unit 186, and can perform 3G communication earliest based on the transport vehicle passage history 1433 and the operation plan 10014. A collection target transport vehicle that is expected to reach the area is determined, and as information indicating the transport vehicle, for example, an IP address of the transport vehicle is transmitted to the target transport vehicle determination unit 185. The determination method of the collection target transport vehicle is, for example, by referring to the transport vehicle passage history 1433, specifying the transport vehicle that has passed the work machine 17030 most recently, and in the operation plan 10014 after the most recent transport vehicle. A transport vehicle expected to reach the 3G communicable area earliest may be selected from a plurality of transport vehicles scheduled to reach work machine 17030.

  With the above processing and configuration, the operation plan is periodically updated at the base server and shared with the work machine via the transport vehicle so that the machine information collection target transport vehicle can be determined with higher accuracy. As a whole, machine information with a high collection priority can be collected earlier.
