The invention provides a method and a system for switching power-saving working modes of a mining intrinsic safety type vehicle-mounted terminal, and relates to the field of vehicle-mounted terminals. The method is applied to an MCU processing unit of the mining intrinsic safety type vehicle-mounted terminal and comprises the steps that a first ignition signal is received, external power supply is connected, and all functional modules of the mining intrinsic safety type vehicle-mounted terminal are started; wherein the function module comprises an intrinsic safety power supply module, and the intrinsic safety power supply module comprises an external power supply and a battery power supply; receiving the flameout signal, and controlling the intrinsic safety power supply module to be switched to battery power supply; when battery power supply is detected, power supply of the camera module is cut off, and a power-saving mode is entered; when it is detected that the battery remaining capacity of the intrinsic sa
