[0002] With the development of the new situation of railway speed increase and transportation safety, it is increasingly important to better ensure the operational safety of self-propelled special equipment. In order to strengthen the operational management of self-propelled special equipment and ensure the driving safety of self-propelled special equipment, it is necessary to install a variety of on-board devices and safety management systems on the self-propelled special equipment to achieve real-time monitoring of the operating status, axle temperature equipment status, driver management, etc. of the self-propelled special equipment.
