The invention discloses an elevator control detection circuit with a controllable discharge loop. The elevator control detection circuit comprises a main circuit breaker, an auxiliary circuit breaker, a contactor control board, a power supply relay board, a contactor combination, a storage battery and the discharge loop. The contactor combination comprises a contactor type relay, a first contactor and a second contactor. The main circuit breaker is used for controlling the on-off of a motor power supply loop by an external network power supply. The auxiliary circuit breaker and the main circuit breaker act synchronously. The contactor control board is used for controlling the on-off of the contactor combination. The power supply relay board outputs direct current to supply power to the contactor control board. The contactor type relay and the first contactor are used for controlling charging and discharging of the storage battery; The discharge loop comprises a resistor combination and a second contactor.
