The invention discloses a safe and reliable railway freight hopper car ground automatic unloading system which comprises a Siemens PLC I. The Siemens PLC I is electrically connected with a relay, a contactor is electrically connected with an unlocking stop block motor and a locking stop block motor, the Siemens PLC I is electrically connected with a proximity switch, the Siemens PLC I is electrically connected with a DC power supply A, and the DC power supply A is electrically connected with a relay. The first Siemens PLC is electrically connected with a measuring light curtain, the first Siemens PLC is electrically connected with a correlation ultrasonic sensor and a second Siemens PLC, the wireless transmission device is wirelessly connected with a network hard disk, and the network hard disk is electrically connected with an industrial switch. According to the safe and reliable automatic ground unloading system for the railway freight hopper car, the two systems are in handshake polling all the time to inform the normal or fault conditions of the systems, the main machine PLC and the auxiliary machine PLC independently transmit remote communication data to the central control board through the industrial switch at the same time, and once an abnormal state occurs, the central control board can be automatically unloaded. The central control board can send out alarm information, pause or process faults.
