The invention relates to a high-voltage cabinet safety monitoring system for electric automobiles. The high-voltage cabinet safety monitoring system comprises high-voltage contactors which are arranged in high-voltage power-on circuits of an electric automobile respectively, and a controller, a plurality of temperature sensors, an acceleration sensor, and a CAN communication module which are arranged in the high-voltage cabinet, wherein detecting ends of the temperature sensors are respectively arranged on bolts in the high-voltage cabinet; temperature signal output ends of the temperature sensors, and an acceleration signal output end of the acceleration sensor are respectively connected with signal input ends of the controller; control signal output ends of the controller are respectively connected with control signal input ends of the high-voltage contactors; a parameter signal output end of the controller is connected with a whole-automobile controller of the electric automobile through the CAN communication module. The high-voltage cabinet safety monitoring system is simple in structure and convenient to use, and adopts the CAN communication module so as to transmit signals acquired by a signal acquisition module to the whole-automobile controller in real time, so that working parameters in the high-voltage cabinet are accurately known in real time, and ensuring the safety of the high-voltage cabinet and the safety of the whole automobile is facilitated.
