Tractor tire pressure multi-state control system

A tractor tire pressure multi-state control system comprises a controller, a pressure sensor and a tire inflation and deflation executing mechanism. A plurality of tire pressure standard values corresponding to different operation forms are preset in the controller, the pressure sensor is used for detecting the tire pressure and transmitting the tire pressure value to the controller, and the controller is used for comparing the tire pressure value with the tire pressure standard values in the controller and intelligently controlling the tire pressure according to the comparison result; and the system further comprises a multi-state selection switch used for selecting operation states is arranged and connected with the controller. Operation is easy and convenient, tractor power can be fully exerted, operation efficiency is improved, and oil consumption is reduced. 一种拖拉机轮胎胎压多态控制系统，包括控制器、压力传感器和轮胎充放气执行机构；在控制器内预设有多种对应不同作业形态的轮胎胎压标准值，压力传感器用于检测轮胎胎压并将轮胎胎压值传送给控制器，控制器用于将轮胎胎压值与控制器内轮胎胎压标准值相比较，并根据比较结果对轮胎胎压进行智能控制；与控制连接设有用于选
