[0002]

2. Description of the Related Art In a display device for a working machine described above, for example, as disclosed in Japanese Patent Application Laid-Open No. 10-75625, when a combine for harvesting and harvesting, which is an example of a working machine, has an abnormal operating state during operation. , The abnormality information relating to the abnormality of the operating state such as the content of the abnormality and the treatment for the abnormality is displayed instead of the normal information on the image display unit that displays the load information of the power plant as the normal information, for example. It was

[0003]

In the above-mentioned prior art, when abnormal information relating to an abnormal operation state occurs, the abnormal information is immediately displayed on the image display section. Even abnormal information that is not necessary to be displayed immediately as information will be displayed instead of normal information each time the abnormal information occurs, and as a result, while viewing the normal information displayed on the image display unit. There is a possibility that the driving operation performed by the operator may be hindered by the sudden switching of the display to the abnormal information and may not be performed properly.

The present invention has been made in view of the above circumstances, and an object thereof is to display the above-mentioned abnormality information in a state where the driving operation of an operator is not hindered as much as possible in order to solve the problems of the above-mentioned prior art.

When 1 changes to the ON state, the self-diagnosis mode is activated.

In the fine adjustment mode, the actual information of each part of the machine is made to correspond to the detection information of each sensor when the respective parts of the machine such as the mowing unit 1 and the threshing unit 2 are in the standard state. Information of a reference value for obtaining the operating state (referred to as fine adjustment data) is stored in the memory MEM.
Specifically, fine adjustment data as exemplified below is stored. (1) Assuming that the left and right direction sensors S1 have returned to the lateral position of the machine body as a reference state, the detection value of each direction sensor S1 at that time (2) As a reference state for the reaping unit 1, the upper limit position is raised. Detection value of the reaper lift detection sensor S12 when the unloader is moved (3) The unloader position sensor S when the unloader 32 is swung to the home position as a reference state
Detected value of 3 (4) Detected value of the rolling sensor S4 when the aircraft V is set in the horizontal state as the reference state

In the normal mode, as shown in FIG. 20, a communication control process for communicating with each high-speed terminal unit LU1-5 and each module MU1-4, a management process of the notification information, a display control process, And work control processing for executing the plurality of controls. In this work control process, the actual operation state of each part of the machine is obtained based on the detection information of each sensor and the stored information of the fine adjustment data, and the actuators A are obtained based on the information of the actual operation state.
Control the operation of K.
