The invention discloses a test method of the reliability of an elevator safety circuit test device comprising an electronic component, and aims at providing a test method capable of automatically judging correctness of an output signal of the safety circuit. The test method comprises the steps of: inputting a test signal to a tested safety circuit by using a PLC (Programmable Logic Controller), monitoring input and output signals of the tested safety circuit by using an industrial personal computer, and judging a logic relation of the input signal and the output signal by the industrial personal computer to realize automatic judgment of the correctness of the output signal of the tested safety circuit. When the output signal of the safety circuit is wrong, a test stopping signal is sent to a test stand by the industrial personal computer, and the test is stopped, thus damage of the safety circuit and energy waste caused by the continuity of the test are avoided.
