Embodiment Construction

[0041] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0042] Embodiment of the control method of a kind of tractor field constant speed operation of the present invention:

[0043] The tractor runs on the field soil at a certain gear, and the running speed of the electric tractor under this gear is obtained. This running speed is the speed of the driven wheel of the electric tractor. The tractor includes the driving wheel and the driven wheel. Generally, the driving wheel refers to the tractor The rear wheel of the tractor, the passive wheel refers to the front wheel of the tractor, therefore, the passive wheel claimed in this embodiment is the front wheel of the tractor, and the driving wheel is the rear wheel of the tractor; Due to problems such as the size of pebbles, there must be a slip rate when the tractor is running in the soil. The allowable range of the slip rate in this embodiment is 10%-3...

Abstract

The invention provides a control method and a device for constant speed operation of a tractor in fields. In a certain gear, if the operating speed of a tractor is less than a theoretical speed of the tractor, an expected angular speed of a motor is calculated according to a slippage rate; the expected angular speed of the motor is set as a control target variable and the angular speed of the motor is controlled to approach the expected angular speed of the motor infinitely. The method takes into consideration the slippage rate of a tractor in operation, thereby according with the requirements of actual working environments, achieving stable and accurate control of a tractor and enabling the performance of a tractor to maintain a good state; further, the method achieves constant speed operation control of a tractor, guarantees tilling quality, reduces labor intensity of a driver and guarantees signal collection precision.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering, and in particular relates to a control method and device for a tractor running at a constant speed in the field. Background technique [0002] During the field work of the electric tractor, due to the softness and hardness of the soil, the height of the terrain, and the size of the stones in the soil, etc., it often slips or does not move when the gear position remains unchanged, so that it can be used for plowing, sowing, etc. In some cases, there will be uneven plowing and inconsistent sowing density, and in this case, the power consumption is fast and the loss of the motor is serious. [0003] In view of the above situation, it is mainly affected by the slip rate. Slip means that the actual distance traveled by the driving wheel is less than the distance that should be traveled during pure rolling. The ratio of the sliding amount on the ground per unit time to the theoretical...
