Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0057] The model of the corn harvester simulated by the present invention is a vertical axial flow grain harvester, and the control module of the corn harvester control system includes: a walking control module, a header control module, a threshing control module and a cleaning control module.

[0058] The walking control module is responsible for the control of the walking speed of the whole vehicle. The engine transmits the power to the hydraulic pump, changes the opening of the walking proportional solenoid valve through the position of the control handle on the armrest box to control the speed of the walking hydraulic motor, and transmits the power to the wheels through the reducer. Control the whole vehicle to walk.

[0059] The header control module is responsible for taking off the ears of corn from the corn plant and sending them to the threshin...

Abstract

The invention relates to a corn harvester intelligent control test platform based on a CAN bus. The corn harvester intelligent control test platform comprises a test platform main body, and a parameter display setting panel, a vehicle control unit, a harvesting controller, a demonstration panel, a test platform operation module, a simulation execution mechanism and a measurement transmitting device which are arranged on the test platform main body; the parameter display setting panel, the vehicle control unit and the harvesting controller are connected through a CAN bus; and the harvesting controller receives and stores a control module of a corn harvester control system to be simulated and debugged, sends a control instruction to the vehicle control unit according to harvesting parametersset by the parameter display setting panel and the control module, and automatically simulates and adjusts the harvesting process. The test platform operation module is connected with an input port of the vehicle control unit; a corn harvester simulation diagram is drawn on the demonstration panel; the simulation execution mechanism comprises a plurality of simulation execution components which are connected with the output port of the vehicle control unit; and the measurement transmitting device collects data signals of all the simulation execution components.

Description

technical field [0001] The invention belongs to the field of agricultural automation, and in particular relates to a CAN bus-based intelligent control test platform for corn harvesters. Background technique [0002] Up to now, the machine yield rate of corn in my country is still at a lower level compared with rice and wheat. In some areas, corn harvesting is still completely dependent on manpower, and the existing corn harvesting machinery is relatively backward in terms of automatic adjustment and automatic control. . The development of domestic corn harvesters should learn from the development direction of foreign corn harvesters, combine the actual situation of domestic corn, and more and more equip CAN bus communication technology and automatic adjustment and control technology in the harvesting process to the control of domestic corn harvesters In the system, the corn harvester control system suitable for the domestic situation is developed. [0003] The field test of...
