In one embodiment, the failure diagnosis module 230 may determine whether the first agricultural work vehicle has a failure using data collected by the data collection device 210 according to a predetermined period. Specifically, the fault diagnosis module 230 arranges the values of the collected data according to a predetermined period on the time axis, and when the slope of the data value for the time axis is greater than or less than 0, the first agricultural work vehicle 10 It can be determined that an abnormality has occurred. In this way, the failure diagnosis module 230 may determine that an abnormality has occurred in the first agricultural work vehicle 10 when the value of the collected data according to a predetermined period increases or decreases.

Furthermore, the fault diagnosis module 230 arranges the values of the collected data according to a predetermined period on the time axis, so that when the slope of the data values on the time axis deviates from the first reference section, the first agricultural work vehicle ( It can be determined that an abnormality has occurred in 10). In this case, the first reference section may be set to a minimum value and a maximum value.

For example, if the minimum value of the first reference section is set to -1 and the maximum value of the first reference section is set to +1, the fault diagnosis module 230 may have a slope of the data value on the time axis between -1 and +1. If it is out of, it may be determined that an abnormality has occurred in the first agricultural work vehicle 10. Accordingly, the failure diagnosis module 230 may determine that an abnormality has occurred in the first agricultural work vehicle 10 when the value of the collected data is in a sharp increase or decrease.

In another embodiment, the failure diagnosis module 230 may determine whether the first agricultural work vehicle 10 has a failure using data collected by the data collection device 210 at a predetermined period for a predetermined period. Specifically, the fault diagnosis module 230 calculates an average value of data collected at a predetermined period for a predetermined period. The failure diagnosis module 230 may determine that an abnormality has occurred in the first agricultural work vehicle 10 when the value of the data currently collected by the data collection device 210 is larger or smaller than the calculated average value.

Further, when the absolute value of the deviation between the calculated average value and the data value collected by the current data collection device 210 is greater than a predetermined reference value, the fault diagnosis module 230 is abnormal in the first agricultural work vehicle 10. It can be determined that this has occurred.

Data can be. Here, the current time point may mean the same time point at which the data of the first agricultural work vehicle 10 is collected.

In another modified embodiment, the remote control server 330 receives the location information of the first agricultural work vehicle 10 from the second communication module 320 and is located outside the first reference radius based on the location information. The above second agricultural work vehicle 340 may be detected. For example, by receiving the location information of the first agricultural work vehicle 10, it is located outside the first reference radius based on the location information, but works in an area with soil similar to that of the first agricultural work vehicle 10 At least one second agricultural work vehicle 340 may be detected.

To this end, a soil quality measurement unit (not shown) may be formed on the first agricultural work vehicle 10 and the second agricultural work vehicle 340. The data collection device 210 may receive soil quality information of a working soil from a soil quality measurement unit of the first agricultural work vehicle 10. The soil quality information received from the soil quality measurement unit of the first agricultural work vehicle 10 may be transmitted to the failure diagnosis module 230 via the database 220.
