Abstract

PURPOSE:To surely enable whole input checks and to simplify operation, by lighting and displaying a pilot lamp related to an automatic control system when the input check results of a group of detecting means constituting the automatic control system are all good. CONSTITUTION:In carrying out input check of a detecting means of each automatic control system, an operator sets an input check switch 56 to on to work an input checking means 60. In this state, for example, a group of detecting means 41, 46, 47, 49... of an automatic control system of depth treatment is handled by the hand to input the signal. Then, every time signals from a group of the detecting means 41, 46, 47, 49... are inputted, whether the signals are good or bad is judged by the input checking means 60. Then, when the input check results of a group of the detecting means 41, 46, 47, 49... are all good, a pilot lamp 31 corresponding to the automatic control device of depth treatment is lighted. Further the same input checking is carried out in other automatic control systems.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to an input check device that checks the input of a detection means such as a sensor. The present invention relates to an input check device for a work vehicle equipped with an automatic control system that performs automatic control such as a work vehicle.

(b) Conventional technology In general, work vehicles, such as combine harvesters, are equipped with automatic mowing, automatic height control, and shallow control during threshing, which appropriately controls the height of the reaping section above the ground, in order to save the operator's complicated operations during the reaping operation. Various automatic controls are carried out, including automatic handling depth control that appropriately controls handling and deep handling, and automatic direction control that automatically steers the traveling machine along the rows of culms.

In order to perform S control for each of these, the cutting height is automatically [8
For cutting height main switch and cutting height sensor, etc.
For automatic handling depth control, a handling depth sensor consisting of a tip sensor, a stock sensor, and a handling depth main sensor, etc., and for automatic direction control, a group of sensors such as a mown side sensor, an uncut side sensor, etc. Each is equipped with switches.

Gl→ Problems to be Solved by the Invention By the way, with the conventional combine harvester mentioned above, when checking the input signals from the sensors and switches of each control system mentioned above during maintenance and shipping, the control group Touch and inspect each sensor, switch, etc.
It is often impossible to determine which of the many sensors and switches belong to the same control group, which makes control system inspection extremely troublesome and may not be carried out reliably.

Therefore, the sensors and switches of each control group are individually operated by hand, and when the input signals from the sensors and switches are normal, the buzzer is configured to sound briefly.
Sensors in each control system.

It is possible to check the switch input, but
Even with this method, as input checks are performed on many sensors and switches one by one, it becomes difficult to know which control system switch was checked, and there is a risk that sensors and switches in the same control system may be overlooked. There is a risk that the control system may be shipped with a defective sensor or the like installed in it because the input is not checked.

Therefore, the present invention is configured such that when all the sensors and switches in the same control system are checked for input, it can be identified that all the sensors and switches in the control system are in good condition by lighting a pilot lamp. It is an object of the present invention to provide an input checking device that solves the above-mentioned problems.

(b) Means for Solving the Problem The present invention has been made in view of the above-mentioned circumstances, and includes a group of detection means (for example, 41,
46, 47, 49), in the work vehicle 1 equipped with each automatic control system that performs automatic control such as handling depth control, the input check means 60 that is activated by operating the input check switch 56 and each automatic control system. A pilot lamp (for example, 31) is provided for each control system, and the detection means (
41, 46, 47, 49), a group of detection means (41, 46, 47, 4
The present invention is characterized in that the pilot lamp (31) related to the automatic control system is turned on and displayed when all input check results in step 9) are good. .

(e) Operation Based on the above-described configuration, when checking the input of the detection means of each automatic control system at the time of shipment or maintenance of the work vehicle 1, the operator turns on the input check switch 56 to activate the input check means 60. , in this state,
For example, a group of detection means 41, 46, 4 in an automatic handling depth control system
7, 49, etc. by hand and input the signal. Then, these groups of detection means 41, 46, 47, 49.
Each time a signal from ... is input, the input check means 6
0 is used to judge whether it is good or bad. If the input check results of the group of detection means 41, 46, 47, 49, . . . are all positive, the pilot lamp 31 corresponding to the automatic depth control system lights up. Furthermore, similar input checks are performed in other automatic control systems as well.
