Problems solved by technology

The traditional self-propelled windrower is composed of a universal power chassis and a header assembly. The transmission mechanism of its moving knife consists of a header transmission box, a transmission box pulley, a cylindrical helical straight tooth main and driven wheels, I shaft, II shaft, Composed of III shaft, elastic coupling, crank, roller shaft, roller handle and moving knife rod, the transmission mechanism is arranged in the middle part of the header assembly as a whole, which realizes the middle drive of the cutting knife within the entire width, and the cutting knife is under force. It is reasonable and has the characteristics of stable transmission of equipment, small vibration, low noise, few faults, reliable work, and good work quality, but the fly in the ointment is that the structure is relatively complicated and the volume is large
Moreover, the control system of the traditional windrower uses switches, relays, and hard wiring to complete the control function. There are a large number of mechanical contacts in the system, and the wiring is cumbersome, and the reliability, maintainability, and expandability are very poor.
The protection level of the system is low, it is not suitable for harsh environments, it is easy to malfunction due to vibration, and the operation is cumbersome and labor-intensive

Abstract

The invention discloses a human-computer interface control system and a control method for a self-propelled swather. The control system comprises sensors, a controller and a display, wherein the controller is connected with the sensors; the display is connected with the controller; the sensors are used for sensing a real-time working state of each part of the swather; the controller is used for receiving information sensed by the sensors and controlling each action of the swather; and the display is used for inputting a control command of a user and displaying an obtained real-time working state parameter of each part of the swather. According to the invention, the control system and a human-computer interface are like the brain of the swather, the control system has the advantages of safety, reliability, easiness for operation and humanization and the automatic level of the swather is improved, so that the swather has higher working efficiency and higher reliability and time, labor and materials can be saved.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and relates to a man-machine interface control system and a control method of a self-propelled windrower. Background technique [0002] The windrower is a kind of grain harvesting machine. Its function is to cut down the stalks of crops such as wheat, and spread them on the stubble to become stalks with lapped ears for drying. Windrower is an important part of agricultural machinery, which is divided into three types: self-propelled, tractor-drawn and suspended. The traditional self-propelled windrower is composed of a universal power chassis and a header assembly. The transmission mechanism of its moving knife consists of a header transmission box, a transmission box pulley, a cylindrical helical straight tooth main and driven wheels, I shaft, II shaft, Composed of III axis, elastic coupling, crank, roller shaft, roller handle and moving knife rod, the transmission mechanism is arran...
