Automatic control system for large-sized cotton picking machine

Abstract

The invention discloses an automatic control system for a large-sized cotton picking machine. The automatic control system comprises a vehicle-mounted electronic control unit (1) of the cotton picking machine and is characterized in that: the vehicle-mounted electronic control unit (1) is connected with an engine assembly signal acquisition module (2), a complete vehicle state switch signal acquisition module (3), a cotton picking head state signal acquisition module (4) and an automatic line aligning sensor signal acquisition module (5) respectively and is used for receiving data of the engine assembly signal acquisition module (2), the complete vehicle state switch signal acquisition module (3), the cotton picking head state signal acquisition module (4) and the automatic line aligning sensor signal acquisition module (5); and the vehicle-mounted electronic control unit (1) is connected with an instrument and meter display module (6), a complete vehicle state indicator light control module (7), a cotton picking head control module (8) and an automatic line aligning device control module (9) respectively and is used for sending control signals of the instrument and meter display module (6), the complete vehicle state indicator light control module (7), the cotton picking head control module (8) and the automatic line aligning device control module (9). In the invention, controller area network (CAN) transmission is realized by embedded equipment, and a general automatic control platform is provided for the cotton picking machine; and a field bus technology is applied to control of the cotton picking machine so as to complete digital transmission of system data and the data acquisition and control of all monitoring points of the cotton picking machine.

Description

technical field [0001] The invention relates to an automatic control system of a large cotton picker, which belongs to the technical field of cotton pickers. Background technique [0002] Large-scale cotton pickers refer to three-row, five-row or six-row self-propelled cotton pickers, which belong to large-scale agricultural machinery and are a symbolic machinery for measuring a country's agricultural technology and equipment. In the world, there are only a few countries such as the United States and China. can be manufactured. With the rapid rise of domestic prices, the cost of manual picking has been soaring, resulting in higher and higher cotton costs. Therefore, the domestic demand for cotton pickers is increasing. There are following shortcoming in prior art. [0003] (1) The prior art has not realized digital control, and the control method is outdated and poor in reliability. [0004] (2) The driving control of the cotton picker and the control of the cotton pickin...

AI Technical Summary

Problems solved by technology

[0003] (1) The existing technology does not realize digital control, the control method is backward and the reliability is poor

[0004] (2) The driving control of the cotton picker and the control of the cotton picking device are independent of each other and have not been integrated

[0005] (3) The control function is weak, and there are no functions such as automatic intercommunication and network control
