The invention relates to a permanent magnetic vacuum circuit breaker control device. A direct current sampling module is used for collecting direct current analog signals, such as a circuit breaker travel distance, excitation currents, and operating voltages; an input acquisition module is used for obtaining digital input signals; an alternating current sampling module is used for sampling alternating current analog signals such as protecting voltages, protective currents and measuring currents; a processing module is used for sending control signals with specified logic according to alternating current signals, voltage analog signals, the digital input signals, the protecting voltages, the protecting currents and the measuring currents; a driving control module is used for controlling the movement of a permanent magnetic vacuum circuit breaker according to the control signals. A synchronous sampling module, the input acquisition module and the alternating current sampling module are adopted for monitoring and controlling alternating current signals and direct current signals in a circuit, when currents or voltages in the current are abnormal, the processing module is used for sending control signals with specified logic of cutting off the breaker, so that the driving control module controls the breaker to open so as to achieve the protection of the breaker.
