Embodiment Construction

[0019] As shown in the figure, the specific implementation method is as follows:

[0020] A control system for a combine harvester. The combine harvester uses an engine as a power source, and a hydraulic pump drives the advance of the combine harvester and the operation of the threshing drum and the harvesting working parts. The control system includes a control system for monitoring the engine The engine ECU, the hydraulic pump ECU used to monitor the hydraulic pump and the threshing drum ECU used to detect the working condition of the threshing drum, the control system is also provided with a front-end controller for receiving the working condition information of the harvesting working parts, for Control the back-end controller of the hydraulic pump ECU, the display for displaying operating parameters and status, and the operating handle for manually controlling the advance of the combine harvester and the operation of the harvesting working parts. The front-end controller, b...

Abstract

The invention discloses a control system for combined harvesters. The control system is characterized in that information of working conditions of threshing cylinders can be monitored in real time by the aid of a rear-end controller of the control system, and control signals outputted to a hydraulic pump ECU (electronic control unit) are automatically reduced and reach zero after running loads of the threshing cylinders are continuously higher than preset values and preset time elapses, so that the combined harvesters can be automatically stopped. The control system has the advantages that working conditions of the integral harvesters can be monitored in real time, so that dynamic conditions of the integral harvesters can be observed in real time; an operation panel input mode and an operation handle input mode are used with each other, so that the control system can be in an automatic mode and a manual mode and is quite convenient; the system can judge the working conditions of the harvesters according to detected loads of the harvesters, the harvesters can be automatically stopped in overload states, accordingly, the harvesters are particularly safe in use, and accidents can be reduced.

Description

technical field [0001] The invention relates to a detection system of a combine harvester, in particular to a working condition monitoring system for a combine harvester. Background technique [0002] With the development of economy and technology, the market for combine harvesters has been expanding year by year, and it has become an indispensable agricultural machine tool in today's rural areas. In order to ensure the normal work and operation of the harvester, people began to install monitoring and detection devices on the harvester to display the driving speed and other working conditions, but the existing detection system can only detect part and part, and cannot effectively control measures, inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide a working condition monitoring system for combine harvesters in order to solve the shortcomings of the above technical problems, which solves the problems of inconvenient c...
