The invention provides a self-adaptive operation speed control system and method for a potato harvester. Through the system and the method, the running speed of an operation machine of the potato harvester and the linear speed of a separating device are adjusted in real time. The self-adaptive operation speed control system for the potato harvester comprises a signal acquisition module, a vehicle-mounted controller, an electromagnetic valve driving module and a monitoring terminal, wherein the signal acquisition module comprises sensors arranged at monitoring points of all working parts on thepotato harvester; the monitoring terminal is used for inputting operation instructions to the potato harvester and displaying working state parameters in real time when the potato harvester is used for harvesting; the vehicle-mounted controller is a fuzzy self-adaptive controller; the signal acquisition module is connected to an input end of the vehicle-mounted controller, an output end of the vehicle-mounted controller is connected with the electromagnetic valve driving module, and the monitoring terminal is connected with the input end and output end of the vehicle-mounted controller.
Description
technical field [0001] The invention relates to an adaptive control system and method for operating speed of a potato harvester [0002] , belonging to the field of agricultural machinery. Background technique [0003] The operating speed of the potato harvester includes the walking speed of the harvester and the linear speed of the potato-soil separation device. [0004] When the potato harvester is harvesting, the driver operates at a constant speed at a set initial speed based on experience (the speed is generally 3-7 km / h). If the operation speed is too fast, it will easily cause blockage, the rate of clear potatoes will decrease, and the traction force will be too large, which will easily lead to machine failure; If the residence time is too long, the rate of potato damage and the rate of broken skin will increase. If the operating speed can be adjusted in real time according to the amount of tuber crops fed, so that the harvester can always work at the optimal speed...
