Embodiment Construction

[0020] Such as figure 1 and figure 2 As shown, the hardware system of the combine harvester operation speed model reference adaptive control device is composed of a controller 2, a touch screen 1, a sensor system 3, a manual / automatic switch 6, and an execution system, wherein the execution system includes an electric control handle 5, a speed Control valve 7 and amplifier 4.

[0021] The sensor system 3 is composed of sensors installed at various monitoring points on the combine harvester 8, including a Hall speed sensor installed on the threshing drum, the grain transport auger and the shaft of the forward wheel, and installed on the shaft of the header auger. The feeding amount sensor on the upper part and the loss amount sensor installed at the tail of the combine harvester 8 sieve. The output of the sensor system 3 is connected to the input of the controller 2 .

[0022] The touch screen 1 is connected to the output end of the controller 2 for displaying the operatin...

Abstract

The invention discloses a device and a method for realizing model reference adaptive control on operation speed of a combine harvester and mainly relates to the field of agricultural machinery. The device is characterized by consisting of a controller, a touch screen, a sensor system, a manual / automatic selector switch and an execution system. The sensor system is used for acquiring signals of a threshing cylinder, a header auger, and a conveying trough, an input amount signal and a loss amount signal and the like of the combine harvester; the manual / automatic selector switch is used for switching between a manual state and an automatic state; the execution system consists of an amplifier, a speed control valve and an electronic control handle; and during work, the controller receives the signals acquired by the sensor system, and the operation speed of the combine harvester is adaptively controlled by a model reference adaptive control algorithm. In the control process, the running state of the combine harvest is displayed by the touch screen, and if the combine harvest is failed, an audible and visual alarm system on the touch screen can perform audible and visual alarm.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an operating speed model reference adaptive control device for a combine harvester. Background technique [0002] With the rapid development of agricultural mechanization, the application of combine harvesters in agricultural production has become more and more extensive, which has greatly promoted the economic development of rural areas. Manipulation comfort and intelligent requirements are getting higher and higher, and it is an inevitable trend for combine harvesters to develop in the direction of intelligence. The operating speed of the combine harvester is determined by factors such as crop density, humidity, field soil conditions, cutting width, etc. Different field environments correspond to different optimal operating speeds. The traditional operation method mainly relies on the driver's personal experience, which has high requirements on the driver's operation leve...
