DETAILED DESCRIPTION

[0030] (Implementation Method 1)

[0031] The operation management system 1000 according to the present embodiment will be described with reference to the accompanying drawings. Figure 1 As shown, the work management system 1000 includes a control device 100 mounted on a work device 30 , a communication terminal 200 , a work management device 300 , and a display terminal 400 .

[0032] The working device 30 performs work while moving, for example, in the field 700. The working device 30 has a manual mode in which the worker moves the working device manually, and an autonomous mode in which the working device 30 autonomously moves along a guide path indicating a preset path. The working device 30 includes, for example, a tractor, a combine harvester, a drone, and the like.

[0033] The control device 100 is mounted on the working device 30, and controls the working device 30 so that it moves along a pre-set guide path when the working device 30 moves in an autonomous mode. For example, the control device 100 measures the current position of the working device 30 when the working device 30 moves in an autonomous mode. For example, the control device 100 receives positioning information from a plurality of artificial satellites 40 and correction information from a fixed station 50 to measure the current position of the working device 30. The control device 100 compares the measured position with the position indicated by the guide path, and controls the working device 30 so that the working device 30 moves along the guide path. Here, the correction information is determined in the fixed station 50, and the correction information is used to correct the positioning information from the artificial satellite 40.

[0034] The communication terminal 200 outputs first communication information indicating the communication status with the control device 100 to the work management device 300 .

[0035] The work management device 300 determines the use information indicating the use status of the correction information transmitted from the fixed station 50 based on the first communication information acquired from the communication terminal 200. For example, the work management device 300 determines the autonomous movement time indicating the time during which the control device 100 controls the work device 30.

[0036] The display terminal 400 displays usage information indicating the usage status of the calibration information, such as an image indicating the autonomous movement time. A user, such as a manager of the fixed station 50, can check the usage status of the calibration information by viewing the usage information. Thus, the user can check whether the fixed station 50 is being used effectively.

[0037] (Structure of the job management system)

[0045] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20.

In addition, the communication device 230 transmits a signal generated by the operation device 220 to the work management device 300.

[0046] In addition, the communication device 230 is electrically connected to the control device 100, and communicates with the control device 100, specifically, the first positioning device 111. The communication device 230 transmits, for example, correction information from the computing device 220 to the working device 30. In addition, the communication device 230 transmits a signal received from the control device 100 to the computing device 220. The communication device 230 includes, for example, a transceiver used in wireless communications such as a wireless LAN (Local Area Network), a cellular network, and short-range wireless communications, a NIC (Network Interface Card), and various interfaces such as a USB (Universal Serial Bus).

[0047] The storage device 240 stores various data for transmitting the correction information to the control device 100, such as the transmission program 510. The storage device 240 is used as a non-transitory tangible storage medium for storing the transmission program 510. The transmission program 510 can be provided as a computer program product recorded in the computer-readable storage medium 2, or can also be provided as a computer program product that can be downloaded from a server.

[0048] The computing device 220 reads and executes the transmission program 510 from the storage device 240 to perform various data processing for transmitting the calibration information. For example, the computing device 220 includes a central processing unit (CPU) and the like.

[0049] The computing device 220 reads and executes the transmission program 510. Figure 3 The information transmission unit 250 is implemented as shown. The information transmission unit 250 receives the calibration information from the fixed station 50 and transmits it to the control device 100. In addition, the information transmission unit 250 outputs the first communication information indicating the communication status with the control device 100 to the work management device 300.

[0050] Next, the structure of the operation management device 300 is described. Figure 5 As shown, the operation management device 300 includes an input-output device 310, a computing device 320, a communication device 330, and a storage device 340. The operation management device 300 is, for example, a computer including a cloud server. Information for processing by the computing device 320 is input to the input-output device 310. In addition, the input-output device 310 outputs the result obtained by the processing performed by the computing device 320. The input-output device 310 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, etc. The input-output device 310 may also be omitted.

[0051] The communication device 330 is electrically connected to the network 20, and communicates with each device via the network 20. The communication device 330 transmits, for example, the first communication information acquired from the communication terminal 200 to the computing device 320. In addition, the signal generated by the computing device 320 is transmitted to the display terminal 400. The communication device 330 includes, for example, various interfaces such as NIC (Network Interface Card) and USB (Universal Serial Bus).

[0052] The storage device 340 stores usage information indicating the usage status of the correction information, for example, various data for determining the autonomous movement time of the working device 30 controlled by the control device 100, such as the control device data 520 and the work management program 530.

The work management program 530 can be provided as a computer program product recorded in the computer-readable storage medium 3, or can also be provided as a computer program product that can be downloaded from a server.

[0053] The control device data 520 indicates information that associates information of the working device 30 controlled by the control device 100, such as an identifier of the working device 30, with an identifier of the first positioning device 111, such as an identifier of a device that receives calibration information from the communication terminal 200. For example, when the first positioning device 111 is connected to the communication terminal 200 via a wireless LAN, the identifier of the first positioning device 111 indicates a physical address of the device connected to the wireless LAN. The identifier of the first positioning device 111 may also indicate a display name of a device used in communication with the communication terminal 200.

[0054] The operation device 320 reads and executes the operation management program 530 from the storage device 340 to perform various data processing for determining the usage information. For example, the operation device 320 includes a central processing unit (CPU) and the like.

[0061] (Operation of the work management system)

[0062] The operation of the work management system 1000 of the present embodiment will be described. First, the process of outputting the first communication information by the communication terminal 200 when the control device 100 controls the work device 30 will be described. For example, an operator using the work device 30 starts the work device 30 in order to work on the field 700. For example, the operator starts the drive device of the work device 30, such as an engine, a motor, etc. When the drive device of the work device 30 is started, the computing device 120 of the control device 100 mounted on the work device 30 reads and executes the control program 500.

[0063] In addition, an operation for outputting the correction information to the control device 100 is input to the input / output device 210 of the communication terminal 200. The computing device 220 of the communication terminal 200 reads and executes the transmission program 510 according to the operation. When the transmission program 510 is read and executed, the computing device 220 starts to execute the operation as part of the work management method. Figure 7 Processing shown.

[0064] In step S110, the information transmission unit 250 implemented by the computing device 220 is connected to the control device 100, specifically, the first positioning device 111, so that the calibration information can be output. For example, the operator selects the first positioning device 111 as the output destination of the calibration information in the input / output device 210 of the communication terminal 200, so as to be connected to the first positioning device 111 of the control device 100. For example, the operator selects an identifier, such as a display name, of the first positioning device 111 in the input / output device 210. In addition, the operator inputs an operation to the input / output device 210 to start transmission of the calibration information.

[0065] In step S120, the information transmission unit 250 obtains the calibration information from the fixed station 50 and outputs it to the first positioning device 111 of the control device 100. For example, the information transmission unit 250 may be configured as follows: Figure 1 As shown in FIG. 1 , the information transmitter 250 receives the correction information via the network 20. Alternatively, the information transmitter 250 may directly receive the correction information from the fixed station 50 by wireless communication. The information transmitter 250 transmits the received correction information to the first positioning device 111 of the control device 100.

[0066] In step S130, the information transmission unit 250 outputs the first communication information indicating the communication status between the communication device 230 of the communication terminal 200 and the first positioning device 111 of the control device 100 to the operation management device 300. For example, the information transmission unit 250 outputs the first communication information indicating the connection between the communication device 230 of the communication terminal 200 and the first positioning device 111 in association with the current time to the operation management device 300. In addition, the information transmission unit 250 may also output information indicating the connected first positioning device 111, such as the identifier of the first positioning device 111, and the first communication information indicating the current time to the operation management device 300.

[0067] In step S140, the first positioning device 111 of the control device 100 measures the position of the working device 30 based on the correction information obtained from the communication terminal 200. For example, the first positioning device 111 measures the position of the working device 30, specifically, the position of the working device 30, using the positioning information and correction information obtained from the artificial satellite 40.

[0068] In step S150, the movement control unit 150 of the control device 100 controls the working device 30 based on the position of the working device 30 so that the working device 30 moves along the preset guide path. For example, the movement control unit 150 compares the position indicated by the guide path with the measured position of the working device 30 and controls the working device 30 so that the working device 30 moves along the guide path. For example, the movement control unit 150 compares the position indicated by the guide path with the position indicated by the second position information and determines the steering angle of the working device 30 for moving the working device 30 along the guide path, and controls the steering angle of the working device 30 to be the determined steering angle.

[0069] In step S160, the movement control unit 150 determines whether the working device 30 is switched to the manual mode of manual movement. When the working device 30 is not switched to the manual mode, specifically, when it is in the autonomous mode (NO), the process returns to step S120 and the process is repeatedly performed. When the working device 30 is switched to the manual mode (YES), the movement control unit 150 stops the measurement of the position based on the first positioning device 111 and transfers the process to step S170. For example, the first positioning device 111 cuts off the communication for receiving the calibration information from the communication terminal 200.

[0070] In step S170 , the information transmission unit 250 of the communication terminal 200 monitors whether the connection with the control device 100 has been cut off.

[0071] In step S180, the information transmission unit 250 outputs the first communication information indicating the communication status between the communication device 230 of the communication terminal 200 and the first positioning device 111 of the control device 100 to the operation management device 300. For example, the information transmission unit 250 outputs the first communication information indicating that the connection with the control device 100 has been disconnected to the operation management device 300 in association with the current time.

[0072] In this way, the information transmission unit 250 of the communication terminal 200 outputs the first communication information indicating the communication status with the first positioning device 111 of the control device 100 using the correction information to the operation management device 300. For example, when the correction information is output to the first positioning device 111, the information transmission unit 250 outputs the first communication information indicating that the communication terminal 200 and the first positioning device 111 can communicate with each other to the operation management device 300. For example, the information transmission unit 250 outputs the information of the first positioning device 111 that outputs the correction information, such as the information indicating the identifier of the first positioning device 111, to the operation management device 300.

[0073] In addition, the information transmission unit 250 outputs the first communication information indicating that the output of the correction information has stopped as a communication status to the operation management device 300. For example, when the connection with the first positioning device 111 that outputs the correction information has been disconnected, the information transmission unit 250 outputs the first communication information indicating that the communication has been disconnected to the operation management device 300.

[0074] The information transmission unit 250 outputs the first communication information to the work management device 300 , thereby outputting information indicating a period during which the correction information is output to the first positioning device 111 that actually uses the correction information to the work management device 300 .

[0075] Furthermore, when the operator moves the working device 30 manually, in other words, when the control device 100 does not control the working device 30, the control device 100 does not use the correction information to measure the position of the working device 30. Therefore, the first positioning device 111 of the control device 100 does not need to obtain the correction information from the communication terminal 200, and the communication terminal 200 does not need to transmit the correction information to the first positioning device 111. Therefore, when the working device 30 moves in the manual mode, no correction information is performed. Figure 7 Instead of the process shown, the operator controls the working device 30.

[0076] Next, the operation management device 300 that has received the first communication information determines the use information indicating the use status of the correction information, such as the time when the correction information is used. When a predetermined time, such as a preset time every day, is reached, the operation device 320 of the operation management device 300 reads and executes the operation management program 530. The operation device 320 may also read and execute the operation management program 530 when receiving a request signal for displaying the use information from the display terminal 400. When the operation device 320 reads and executes the operation management program 530, execution of the operation management method as part of the operation management method is started. Figure 8 Processing shown.

[0077] In step S210 , the information acquisition unit 350 implemented by the computing device 320 acquires the first communication information from the communication terminal 200 .

[0078] In step S220, the information determination unit 360 determines usage information indicating the state of use of the correction information, such as the time of use, based on the first communication information. The first communication information includes information indicating the state of use of the correction information. Figure 7 The first communication information includes information indicating the time at which the correction information is sent to the device that actually uses the correction information, specifically, the first positioning device 111, by processing in step S130. Figure 7 The information determining unit 360 stops transmitting the time information to the device that actually uses the correction information by performing the process of step S180. Therefore, the information determining unit 360 determines the time to use the correction information based on the time indicated by the plurality of first communication information.

[0079] For example, the information determination unit 360 extracts the start time of transmission of the correction information from among the times associated with the first communication information indicating that the communication terminal 200 and the first positioning device 111 are connected. Fig. 9 As shown, the information determination unit 360 extracts a plurality of connection times 600 associated with a plurality of first communication information indicating that the communication terminal 200 and the first positioning device 111 are connected. The information determination unit 360 determines the first connection time 600-1 among the connection times 600 as the start transmission time indicating the time when the communication terminal 200 starts to transmit the correction information to the first positioning device 111.

[0080] Next, the information decision unit 360 extracts the stop transmission time at which the transmission of the correction information is stopped from among the times associated with the first communication information indicating that the connection between the communication terminal 200 and the first positioning device 111 has been disconnected. For example, the information decision unit 360 extracts the disconnection time 610 associated with the first communication information indicating that the connection between the communication terminal 200 and the first positioning device 111 has been disconnected. The information decision unit 360 determines the first disconnection time 610-1, which is later than the start transmission time, for example, the first connection time 600-1, as the stop transmission time at which the transmission of the correction information is stopped.

[0081] The information decision unit 360 determines the time from the start of transmission to the stop of transmission as the time for using the correction information. In addition, the information decision unit 360 may also determine the time from the start of transmission to the stop of transmission as the autonomous movement time 620 for the control device 100 to control and move the working device 30 using the correction information.

[0082] When there is a connection time 600 after the stop transmission time, for example, the first disconnection time 610-1, the information decision unit 360 determines the second second autonomous movement time 620-2 in addition to the first first autonomous movement time 620-1. For example, the information decision unit 360 determines the stop transmission time, for example, the first disconnection time 610-1, which is later than the first autonomous movement time 620-1 and is the first connection time 600, for example, the second connection time 600-2, as the second start transmission time. In addition, the information decision unit 360 determines the first disconnection time 610, for example, the second disconnection time 610-2, which is later than the second start transmission time, for example, the second connection time 600-2, as the second stop transmission time. The information decision unit 360 determines the time between the second start transmission time and the second stop transmission time as the second autonomous movement time 620-2.

[0083] The information determination unit 360 may determine the third and subsequent autonomous movement times 620 in the same manner.

[0084] In this way, the information determination unit 360 determines the time to send the correction information to the device that uses the correction information, such as the first positioning device 111. In addition, the information determination unit 360 can also determine the working device 30 controlled by the control device 100 based on the information indicating the connected device, such as the first positioning device 111, included in the first communication information, and the control device data 520. For example, the information determination unit 360 extracts the information of the working device 30 stored in association with the information indicating the first positioning device 111, such as the identifier, from the control device data 520. The information determination unit 360 determines the working device 30 indicated by the extracted information as the working device 30 controlled by the control device 100.

[0085] exist Figure 8 In step S230, the output unit 370 outputs the determined usage information, for example, information indicating the autonomous movement time 620, to the display terminal 400. The usage information may include information indicating the working device 30 controlled by the control device 100.

[0086] In step S240, the display unit 450 of the display terminal 400 displays the use information acquired from the work management device 300, such as information indicating the autonomous movement time 620, on the input / output device 410. For example, the display unit 450 displays information indicating the work device 30 controlled by the control device 100, such as the name of the work device 30 and information indicating the autonomous movement time 620. A user, such as a manager of the fixed station 50, can confirm the actual use status of the correction information, such as the use time (such as the autonomous movement time 620), based on the use information displayed on the input / output device 410.

[0087] (Implementation Method 2)

[0088] The usage information provided to the user is not limited to the time when the correction information is used, but can also indicate any information that can be obtained. For example, the control device 100 can output operating information indicating the state of the working device 30, such as the position, speed, steering angle, etc., to the work management device 300. In addition, the operating information includes information indicating the first positioning device 111 of the control device 100, such as information indicating the identifier of the first positioning device 111. The work management device 300 determines the usage information indicating the work of the working device 30 as the status of using the correction information based on the first communication information and the operating information. For example, the work management device 300 determines the operating information corresponding to the first communication information based on the information indicating the first positioning device 111 included in the first communication information and the information indicating the first positioning device 111 included in the operating information.

[0089] For example, when the operation information includes position information indicating the position of the working device 30, as shown in FIG. Fig.10 As shown, the work management device 300 can determine the use information indicating the manual path 820 and the autonomous path 830. The manual path 820 indicates a path for the work device 30 to be moved manually by the operator without using the correction information. The autonomous path 830 indicates a path for the work device 30 to be moved autonomously using the correction information. For example, the work management device 300 determines the autonomous movement time 620 based on the first communication information. In addition, the work management device 300 determines the autonomous path 830 for the work device 30 to move within the autonomous movement time 620, and the manual path 820 based on the operation information corresponding to the first communication information.

[0090] The operation information may include status information indicating the status of each machine of the working device 30, such as the ON / OFF status of various clutches. In addition, when the working device 30 is a vehicle that tows a working machine, such as a tractor, the status information may also include information such as the PTO (power take-off) speed when transmitting power to the working machine, the pitch height indicating the posture of the working machine, and the boom angle. The status information may also include information indicating the harvest amount of crops harvested by the working device 30.

[0091] (Structure of the job management system)

[0092] The structure of the work management system 1000 of this embodiment is described. Fig.11 As shown, the control device 100 included in the operation management system 1000 includes an input / output device 110, a first positioning device 111, a second positioning device 112, a computing device 120B, a communication device 130B, and a storage device 140. The control device 100 includes, for example, a computer, a tablet computer, a mobile phone, etc. The input / output device 110, the first positioning device 111, and the storage device 140 are the same as those in the first embodiment, so detailed descriptions are omitted.

[0093] The second positioning device 112 measures the position of the machine at each time and measures the position of the working device 30 on which the machine is mounted. For example, the second positioning device 112 measures the position of the working device 30 at a predetermined time interval, for example, at an interval of 10 seconds. The second positioning device 112 is, for example, a GNSS (Global Navigation Satellite System) receiver, a quantum compass, etc. Figure 1 As shown, the second positioning device 112 receives positioning information from a plurality of artificial satellites 40 and measures the position of the working device 30. The position measured by the second positioning device 112 does not use correction information, so the accuracy is lower than the position measured by the first positioning device 111. In addition, the second positioning device 112 measures the position of the working device 30 regardless of whether the working device 30 is in the autonomous mode or the manual mode.

[0094] Fig.11 The communication device 130B shown communicates with the working device 30. For example, the communication device 130B transmits a signal generated by the computing device 120B, such as a control signal for controlling the working device 30, to the working device 30. In addition, the communication device 130B obtains status information from the working device 30 and transmits it to the computing device 120B.

[0095] In addition, the communication device 130B is electrically connected to the network 20, and communicates with each device via the network 20. For example, the communication device 130B transmits the operation information obtained from the operation device 120B to the operation management device 300. In addition, the communication device 130B transmits the signal received from the operation management device 300 to the operation device 120B. The communication device 130B includes, for example, a transceiver used in wireless communication such as a wireless LAN (Local Area Network) and a cellular network, a transceiver used in wired communication such as a CAN (Controller Area Network), a NIC (Network Interface Card), and a USB (Universal Serial Bus) and other various interfaces.

[0096] The computing device 120B reads and executes the control program 500 from the storage device 140 to perform various data processing for controlling the working device 30 and outputting operation information. For example, the computing device 120B includes a central processing unit (CPU) and the like.

[0097] The computing device 120B reads and executes the control program 500. Fig.12 The movement control unit 150 and the information output unit 160 are implemented as shown. The movement control unit 150 is the same as that in Embodiment 1, so the detailed description is omitted. The information output unit 160 obtains the state information of the work device 30 from the work device 30, and outputs the operation information including the state information and the position information to the work management device 300.

[0098] The configuration of communication terminal 200 is the same as that of Embodiment 1, and therefore detailed description thereof will be omitted.

[0099] The configuration of the work management device 300 is the same as that of the first embodiment except for the information determination unit 360B which is realized by the operation device 320 reading and executing the work management program 530, so detailed descriptions of the configuration other than the information determination unit 360B are omitted. The information determination unit 360B determines the usage information indicating the usage status of the correction information based on the first communication information and the operation information of the work device 30.

[0100] The configuration of the display terminal 400 is the same as that of the first embodiment, and therefore a detailed description thereof will be omitted.

[0101] (Operation of the work management system)

[0102] The operation of the work management system 1000 of this embodiment will be described. When the movement control unit 150 of the control device 100 controls the work device 30, the communication terminal 200 outputs the first communication information. This process is the same as that of the first embodiment, so the detailed description is omitted.

[0103] Next, the process of the control device 100 outputting the operation information of the work device 30 to the work management device 300 will be described. The information output unit 160 of the control device 100 outputs the operation information of the work device 30 to the work management device 300. For example Fig.10 As shown, the information output unit 160 acquires position information indicating the positioning position 800 measured by the second positioning device 112 at each time. In addition, the information output unit 160 acquires the state information of the working device 30 from the working device 30 at each time. The information output unit 160 outputs the operation information including the state information and the position information and associated with the time when each information is acquired to the working management device 300. For example, when the driving device of the working device 30 stops, the information output unit 160 outputs the operation information from the start to the stop of the driving device to the working management device 300. In addition, the information output unit 160 can also output the acquired operation information to the working management device 300 in sequence.

[0104] Next, the process of determining the usage information by the operation management device 300 will be described. As in the first embodiment, when a predetermined time, such as a preset time every day, is reached, the operation device 320 of the operation management device 300 reads and executes the operation management program 530. The operation device 320 of the operation management device 300 may also read and execute the operation management program 530 when receiving a request signal for displaying the usage information from the display terminal 400. When the operation device 320 reads and executes the operation management program 530, execution of the operation management method as part of the operation management method is started. Fig.13 Processing shown.

[0105] In step S210B, the information acquisition unit 350 implemented by the computing device 320 acquires the first communication information from the communication terminal 200 , and acquires the operation information from the control device 100 .

[0106] In step S220B, information determination unit 360B determines usage information indicating a state of using correction information based on the first communication information and the operation information. For example, first, similarly to Embodiment 1, information determination unit 360B determines a time for using correction information, such as autonomous movement time 620, based on the first communication information. The process of determining the time for using correction information is the same as Embodiment 1, and therefore, detailed description thereof is omitted.

[0107] Next, the information determination unit 360B determines the use information indicating the work of the work device 30 during the time when the correction information is used, based on the operation information of the work device 30. Fig.10 As shown, the information determination unit 360B determines the moving path 810 of the working device 30 based on the position information included in the operation information. For example, the information determination unit 360B determines the moving path 810 by connecting the positioning positions 800 with a line, such as a straight line segment, in the order of the time when the positioning positions 800 are associated. The information determination unit 360B determines the path corresponding to the time when the correction information is used, such as the position information included in the autonomous moving time 620, among the determined moving paths 810 as the autonomous path 830. For example, when the autonomous moving time 620 is the time from the time when the first positioning position 800-1 is associated to the time when the second positioning position 800-2 is associated, the information determination unit 360B determines the path from the first positioning position 800-1 to the second positioning position 800-2 as the autonomous path 830. The information determination unit 360 determines the path other than the autonomous path 830 among the moving paths 810 as the manual path 820.

[0108] In this way, the information determination unit 360B determines the use information based on the operation information corresponding to the time when the correction information is used. In addition, the information determination unit 360 can also determine the working device 30 controlled by the control device 100 based on the information indicating the connected device, such as the first positioning device 111, included in the first communication information, and the control device data 520.

[0109] exist Fig.13 In step S230, the output unit 370 outputs the determined usage information, such as information indicating the manual path 820 and the autonomous path 830, to the display terminal 400. For example, the output unit 370 outputs information indicating an image that can recognizablely represent the manual path 820 and the autonomous path 830 on a map. The usage information output by the output unit 370 may also include information indicating the working device 30 moving along the manual path 820 and the autonomous path 830.

[0110] In step S240, the display unit 450 of the display terminal 400 displays the use information acquired from the work management device 300, such as information indicating the manual path 820 and the autonomous path 830, on the input / output device 410. For example, the display unit 450 displays an image that indicates the manual path 820 and the autonomous path 830 in a recognizable manner on a map. The display unit 450 may also display information indicating the work device 30 moving along the manual path 820 and the autonomous path 830. The user can confirm the path along which the work device 30 is moved using the correction information based on the use information displayed on the input / output device 410.

[0111] (Variation Example)

[0112] The above-described embodiments and modifications are examples, and the structures described in the embodiments and modifications can be arbitrarily changed or / and combined without hindering the functions. In addition, as long as the required functions can be achieved, some functions described in the embodiments and modifications can be omitted.

[0113] In the second embodiment, the information determination unit 360 may Fig.10 The boundary between the manual path 820 and the autonomous path 830 is set between two adjacent positioning positions 800 at the time of measurement. For example, the boundary between the manual path 820 and the autonomous path 830 can be determined as any position between two positioning positions 800, such as the second positioning position 800-2 and the third positioning position 800-3, which are adjacent to each other at the time of measurement and one is included in the autonomous path 830 and the other is included in the manual path 820. For example, the boundary between the manual path 820 and the autonomous path 830 can be determined as the midpoint between the second positioning position 800-2 and the third positioning position 800-3.

[0114] The usage information determined by the information determination unit 360 is not limited to the path along which the working device 30 moves, and may also indicate any information for indicating the operation of the working device 30. For example, the usage information may indicate the position of the working device 30 when the calibration information is used without connecting the positioning positions 800 with a line. For example, the usage information may indicate the operation area of ​​the area where the working device 30 performs the operation using the calibration information. For example, the information determination unit 360 extracts the operation information when the working device 30 uses the calibration information and performs the operation from the plurality of operation information based on the first communication information. For example, the information determination unit 360 extracts the operation information measured during the time when the working device 30 moves using the calibration information as the operation information when the working device 30 uses the calibration information and performs the operation. The information determination unit 360 determines the convex hull for the positioning position 800 indicated by the extracted operation information, and determines the determined convex hull as the operation area where the working device 30 performs the operation using the calibration information. In addition, the information determination unit 360 may determine the area obtained by expanding the convex hull by the operation width of the working device 30 as the operation area.

[0115] In addition, when the operation information includes information indicating the harvest amount of crops harvested by the working device 30 , the usage information may indicate the harvest amount of crops harvested by the working device 30 within the autonomous movement time 620 .

[0116] In Embodiment 2, when the control device 100 controls the working device 30, the second positioning device 112 may not measure the position of the working device 30. In this case, the information output unit 160 of the control device 100 may output position information indicating the position measured by the first positioning device 111 to the working management device 300.

[0117] In the above embodiment, the control device 100 can be divided into multiple parts. For example, the input / output device 110 can be set to be separable from the control device 100. For example, the input / output device 110 can be set to be separable from the control device 100 and connected to the computing device 120, 120B to communicate wirelessly. For example, the operator can operate the input / output device 110 without riding the working device 30 to make the working device 30 move autonomously.

[0118] in addition, Fig.11 The control device 100 shown can be divided into a first control device including a first positioning device 111 and a second control device including a second positioning device 112. In addition, the first positioning device 111 and the second positioning device 112 may have a common part or may be formed integrally. For example, the integrally formed positioning device may function as the first positioning device 111 when receiving correction information from the fixed station 50, and may function as the second positioning device 112 when not receiving correction information.

[0119] exist Figure 8 Step S220 or Fig.13 In step S220B shown in FIG. 1 , the information decision unit 360 may determine that the transmission of correction information from the communication terminal 200 to the control device 100 has stopped based on the first communication information indicating that the communication terminal 200 is connected to the control device 100. For example, when the interval between two first communication information indicating the connection between the communication terminal 200 and the control device 100 that are adjacent in time reaches a predetermined period or longer, the information decision unit 360 may determine that the transmission of correction information from the communication terminal 200 to the control device 100 has stopped. In this case, the information decision unit 360 may be omitted. Figure 7 The processing of steps S170 and S180 is shown.

[0120] exist Figure 7 In the illustrated process, an example is shown in which the information transmission unit 250 of the communication terminal 200 outputs the first communication information every time correction information is output, but the present invention is not limited thereto. For example, the information transmission unit 250 may output the first communication information when starting to output correction information and when stopping to output correction information.

[0121] The information acquisition unit 350 of the operation management device 300 may determine the use information using the second communication information indicating the communication status between the fixed station 50 and the communication terminal 200. For example, the second communication information may be obtained from the fixed station 50 or from the information transmission unit 250 of the communication terminal 200. For example, the use information may indicate the time when the correction information is actually used and the time when the communication terminal 200 obtains the correction information from the fixed station 50. In this case, the fixed station 50 outputs the second communication information indicating the time when the transmission request for requesting the transmission of the correction information is received from the communication terminal 200 and the time when the stop request for requesting the stop of the transmission of the correction information is received to the operation management device 300. In addition, the information transmission unit 250 of the communication terminal 200 may output the second communication information indicating the time when the transmission of the correction information is requested to the fixed station 50 and the time when the transmission of the correction information is requested to be stopped to the operation management device 300. For example, the operation management device 300 determines the time from the time when the transmission of the correction information is requested to the time when the transmission of the correction information is requested to be stopped as the output time when the fixed station 50 outputs the correction information to the communication terminal 200.

[0122] In this case, display unit 450 of display terminal 400 displays an image showing, in a comparable manner, the time when correction information is used and the time when correction information is output from fixed station 50 to communication terminal 200. Display unit 450 of display terminal 400 may also display information showing the ratio of the time when correction information is used to the time when correction information is output from fixed station 50 to communication terminal 200.

[0123] The work management device 300 may acquire the first communication information indicating the communication status with the corresponding control device 100 from the plurality of communication terminals 200. In this case, the information acquisition unit 350 of the work management device 300 identifies the first communication information corresponding to each control device 100 based on the information of the first positioning device 111 indicated by the first communication information. The information determination unit 360 determines the usage information indicating the usage status of the use correction information for each work device 30 corresponding to the control device 100 based on the first communication information corresponding to the control device 100 and the operation information.

[0124] The fixed station 50 may include a server that controls the transmission of correction information from the fixed station 50 to the communication terminal 200. For example, when requesting correction information from the fixed station 50, the information transmission unit 250 of the communication terminal 200 outputs information for requesting correction information from the server of the fixed station 50, such as qualification information. For example, the server of the fixed station 50 controls the fixed station 50 in such a manner that the correction information, such as the account name and password, is confirmed and the correction information is started to be transmitted to the communication terminal 200. In addition, the correction information may be transmitted to the communication terminal 200 via the server of the fixed station 50. In addition, the first communication information may be output from the communication terminal 200 to the operation management device 300 via the fixed station 50 or the server of the fixed station 50.

[0125] For example, the process of display terminal 400 may be executed by control device 100 or job management device 300. Also, the process of job management device 300 may be executed by control device 100 or display terminal 400. Job management program 530 may include one or more of control program 500, transfer program 510, and display program 540.

[0126] In addition, the display terminal 400 may not be included in the work management system 1000. For example, the output unit 370 of the work management device 300 may output the usage information to a terminal outside the system, and display the usage information on the terminal outside the system.

[0127] The communication terminal 200 may not be included in the work management system 1000. For example, the work management device 300 may acquire first communication information indicating a communication status between a device using correction information, for example, the control device 100, and the communication terminal from a communication terminal outside the system.

[0128] In addition, the control device 100 may not be included in the work management system 1000. For example, the work management device 300 may acquire the operation information from a control device external to the system mounted on the work device 30.

[0129] In addition, a part or all of the control device 100 may be incorporated in the working device 30. In addition, the working device 30 may perform work outside the field 700.
