Abstract

PURPOSE:To check quantitatively an operation of a control device by providing a parameter display device by which a duty ratio of on and off is varied continuously in accordance with a variation of a detecting signal from a sensor. CONSTITUTION:A titled machine is provided with a parameter display device by which a duty ratio of on and off is varied continuously in accordance with a variation of the respective detecting signals of each sensor. For instance, an input interface 9 to which a signal from each sensor S1, S2 is inputted at a regular time, and an output interface 10 for outputting a control signal to a device to be controlled are connected respectively or individually to a parameter display device 14, and basing on a combination of switches SW1, SW2, a diagnostic program is selected. Subsequently, in accordance with the selected program, the corresponding display parts 15a-15d of a display part 15, irradiated by lamps L1-L4. Thereafter, lamps l1-ln corresponding to an item which requires a check are flickered by a duty ratio corresponding to a variation of a detecting signal from the sensors S1, S2, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reaping and harvesting machine, and more specifically, it has sensors that detect various parameters that continuously change, such as engine rotation speed, traveling speed, and the position of a working device. Based on the results, the grain culm is harvested as the aircraft moves forward.
The present invention relates to a reaping harvester equipped with a control device that continuously and automatically performs threshing processing operations.

Conventionally, various controls such as cutting height control and working speed control are generally performed in this type of reaping/harvesting machine, but in recent years so-called microcomputers have been increasingly used as the control device.

When this microcomputer is used as a control device, it is possible to perform various controls by simply changing the software control program, even though the hardware has the same configuration, and the operation of the controlled device (work device) can be easily controlled. Although this device has a very large effect that conventional control devices do not have, it is difficult to quantitatively check its operation.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a reaping harvester equipped with means capable of quantitatively checking the operation of a control device.

In order to achieve the above object, the reaping/harvesting machine according to the present invention responds to changes in the detection signals of the respective sensors.
It is characterized in that it is equipped with a parameter display device that continuously changes the OFF detent ratio.

Due to the above features, the following excellent effects have been achieved.

In other words, it turns on and off in response to changes in the detection signal from each sensor.
By using a parameter display device in which the duty ratio of 0F11'' changes continuously, it has become possible to easily and reliably quantitatively check the operation of the control device and sensors by using a single display device.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG.
Equipped with 1/+ fuselage (11 with threshing device (31, control section (
4) and an engine (E) as a power source are mounted on the fuselage 11+, a pulling device IS1 at the front, a reaping device (61), and a threshing device (31) at the rear to merge the harvested grain culms. A reaping section (81) consisting of a feeding conveyance device (7) and the like is provided to constitute a combine harvester as a reaping/harvesting machine.

The crawler traveling device (211, the threshing device 131, the engine (El, etc.) and other rotating devices are provided with a sensor (Sl) for detecting the rotation speed, and the conveying device (71 and the reaping section (8) ) and other devices that move in position are equipped with a sensor (S3) that detects the position and orientation (angle) of each device, and is configured to continuously detect the state of the device that requires control. (The positions of each sensor are not shown.) As the sensor (81), a type of sensor that continuously generates a pulse train of a frequency corresponding to the rotational speed of the detected device is used. , a sensor (S...) that detects the position (angle),
A type of sensor such as a rotary encoder or potentiometer that can obtain a signal output corresponding to a change in position (rotation angle) is used.
