Automatic switching control system and method for walking gears of milling machine

The invention discloses an automatic switching control system and method for walking gears of a milling machine. The system is characterized by comprising a controller, an electric control handle, a walking gear shifting switch and a milling drum starting and stopping switch electrically connected with the input end of the controller, and a walking driving pump proportional valve, a milling drum driving electromagnetic valve and a gear shifting electromagnetic valve electrically connected with the output end of the controller. The electric control handle is electrically connected with an analog signal input interface of the controller, the walking gear shifting switch and the milling drum starting and stopping switch are electrically connected with a digital signal input interface of the controller, and the controller can store the gear state of the milling drum in the starting state and the gear state of the milling drum in the stopping state in real time. According to the automatic switching control system
