The invention relates to an elevator safety circuit first fault capturing system and a using method thereof. In order to fill the blank in the prior art, the elevator safety circuit first fault capturing system comprises a plurality of fault signal sensors, a PLC and a human-computer interface, and a bit-to-double-word module, a first-in-first-out module, a double-word transposition module, a falling edge detection module and a digital signal analysis module are arranged in the PLC. The first-in first-out unit can latch a plurality of double-word signals, a newly received double-word signal automatically covers the first received double-word signal, the above modules are connected in sequence, the bit-to-double-word module is connected with each fault signal sensor, and the digital signal analysis module is connected with a human-computer interface. The elevator safety circuit first fault capturing system and the using method thereof have the advantages of being scientific in design and reliable in operation, are suitable for capturing the elevator safety circuit first fault, and are beneficial to quickening inspection and maintenance of the elevator.
