Description

technical field [0001] The invention relates to a traction logic control device for underground explosion-proof electric drive vehicles, which belongs to the technical field of traction logic control for underground electric drive vehicles. Background technique [0002] Underground diesel engine trackless rubber-tyred vehicles have been widely used in coal mines, but the pollution of diesel engines has also brought adverse effects on the environment in coal mines. In recent years, the zero-pollution characteristics of pure battery vehicles have attracted much attention. Based on this, there are It is necessary to invent a brand-new traction logic control device for underground electric drive vehicles to solve the problems of severe environmental pollution and serious harm to the health of miners with existing underground drive technology, and the unreliable control of underground explosion-proof electric drive vehicles. The underground environment is extremely complex. In or...
