In the case of a tractor, sensors 11 and 12 regarding the plowing depth and the type of work are installed depending on the type of the work machine. In the case of combine C, sensors related to yield, paddy moisture, footjob depth, and vehicle height are installed. Furthermore, in the rice transplanter, sensors 11 and 12 regarding the number of planted mats, the amount of fertilizer applied, the number of tillages, etc. are installed. In addition, various information is automatically and immediately transmitted from the sensors 11 and 12 to the service center S. In addition, the monitor 3 displays the communication status with the service center S or the sales office L, which will be described later. With the above configuration, the status of the work equipment can be grasped from the monitor 2 displaying the sensor result and from the monitor 3 from the communication status with the service center at the driver's seat.

【0010】

(Equipment configuration) The various sensors 11, 12 ... Of the combine C are connected to the controllers 21, 22 ... As shown in FIG. 1 or 5, and each of the controllers 21, 22 ... Is a storage medium. It is connected to the 25 and the monitor 2, and the information of the storage medium 25 is conveyed to the service center S through the mobile phone 30, PHS, satellite line 31, and the like. Therefore, the operation information from the various sensors 11, 12 ... Is temporarily stored in the storage medium 25 provided in the combine C main body, and is constantly communicated using a communication means such as a mobile phone 30, PHS, or satellite line 31. It is sent to the service center S by the packet method.

【0011】

(Memory retention for a certain period of time) The storage medium 25 on the combine C main unit stores information (information in normal operation) from the controllers 21, 22 ... in the storage medium 25 until a certain time before the present. .. When a trouble occurs, the above information related to the trouble (information up to a certain time ago) is sent to the service center S and the sales office L by communication means.

【0012】

(Monitor 3) Further, as shown in FIG. 4, a monitor 3 is provided in addition to the normal monitor 2 on the combine C side, and as shown in FIG. 6, a user (operator) can display the bidirectional communication result with the service center S. ) Is transmitted by image (monitor 3) or voice. Further, a microphone 4 and a speaker 5 are provided in the vicinity of the monitor 3, and information can be exchanged by voice between the operator on the combine C side and the service center S or the like. Naturally, a similar device is attached to the computer on the service center S side. Further, the monitor 3 is also provided with a self-diagnosis function button, and the operator can activate and display the self-diagnosis function by turning on the button as appropriate.

(Service Center S) As shown in Fig. 8, Service Center S grasps all the information sent from several combine harvesters C ... in the jurisdiction simultaneously or as needed by the monitor 32. To do. In this case, instead of the service center S or in addition to the service center S, the service person may be communicated with the service person by a mobile phone. In addition, by storing all the information sent from combine C ... in the database 33, it is possible to view it only when a trouble occurs. When a trouble occurs in combine C, the information of the past fixed time is sent from the combine C side automatically or manually, so the information of the normal state and the information of the trouble state are compared. As a result, the cause of the trouble can be immediately identified at the service center S, and the user (operator) is notified of the inspection location by voice or / and data, and prompt response to the user (arrangement of abnormal parts). Etc.) can be done.

【0014】

For example, by accumulating the working time, an instruction to change the oil and trouble information will inform the user of the inspection point. At the service center S, information related to the maintenance of the combine C is basically exchanged, and the sales office L is responsible for the recovery work of the failure. However, if the service center S and the sales office L are in the same place, information transmission becomes easier. As shown in FIG. 7, wireless communication may be performed directly via a communication satellite, but as shown in FIG. 9, information is transmitted and received using normal communication by a mobile phone or communication via a computer. You may.

【0015】

(Sales office L) As shown in FIGS. 1 and 8, the sales office L takes trouble-solving measures for the combine S based on the information on the failure and failure recovery from the service center S. Information processing and communication systems are also provided at this sales office L, making it easy to communicate with combine harvesters C and service personnel in the field.

【0016】

(Failure detection) There are various types of failures, and uniform detection means cannot be adopted, but quantitative changes in the amount of work, that is, volume troubles are troubles when the volume voltage is not in the 0.5 to 4.5V range. Judge. If the data before a certain period of time is stored from the time when the trouble is determined, it can be seen that the voltage temporarily becomes 0V, and it can be determined that the volume has a poor contact. Therefore, the component in which the sensor that caused the volume trouble is installed is the faulty part.

【0017】

Data before a certain time (V) 3.00 2.98 2.96 3.95 0.00 Suddenly drops to 0V 0.00 Trouble judgment 0.00 2.77 2.74 [0018]

(Separate Example) As an addition to the above-mentioned Example, in the event of a fire, in addition to transmitting to the service center S, the combine C may systematically arrange automatically directly from the combine C to the fire department. Furthermore, at agricultural cooperatives, etc., agricultural work such as renting, rice planting, and harvesting is undertaken by farmers, but the agricultural cooperative sometimes works in a field different from the field designated by the farmer, but this is prevented. As a means, mark the area to be requested for agricultural work on the map information, make a reservation with the agricultural cooperative on the Internet, etc., and the agricultural cooperative will work according to the instructions on the map using GPS (Global Positioning System) radio waves to the contractor. By doing so, the occurrence of the above problem is solved.

【0019】

Further, the operation information may be stored in the system on the service center S side instead of the combine C side for a certain period of time in the past. Although the above embodiment shows an example of a combine harvester, it goes without saying that it can be applied not only to other agricultural machines but also to construction machines, transport vehicles and the like.
