The current receiving system of the urban railway vehicle is direct current, and the national railway line supplies power to alternating current, so that the urban railway vehicle needs to carry out unpowered loopback, a traction system does not work in the loopback process of the vehicle, and only a braking system is put into use. The existing loopback scheme is only converted by a loopback device according to a braking command and a level applied by an urban railway vehicle, the braking system of the urban railway vehicle applies and relieves the braking command, the state cannot be monitored, usually, when the vehicle arrives at a stop station, a worker manually observes the state of applying or relieving the braking of the vehicle, and during the running process, the vehicle wheel rubbing and the full-train wheel pair are locked, even a fire disaster is caused, and great loss is caused. Meanwhile, the urban railway vehicle is not provided with a toilet, so that no person watches the vehicle in the returning process, the vehicle is often braked and not relieved, or the power supply is controlled to lose power, and the like, so that a larger accident is easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a loopback monitoring system of an urban railway vehicle, which can monitor the application and release states of service braking and emergency braking of the urban railway vehicle and remind personnel in the loopback vehicle to carry out fault treatment in time when the states are abnormal.

In order to achieve the above object, the present invention provides a loopback monitoring system for an urban railway vehicle, characterized in that: the urban railway vehicle loopback connector plug on the urban railway vehicle is butted with the urban railway vehicle loopback connector socket on the loopback vehicle, so that a brake release state negative line, a DC110V monitoring positive line, a DC110V monitoring negative line, a DC110V power supply positive line, a DC110V power supply negative line and an emergency brake positive line between the urban railway vehicle and the loopback vehicle are communicated; the acousto-optic alarm device on the return vehicle, the return connector socket of the urban railway vehicle, the return connector plug of the urban railway vehicle on the urban railway vehicle and the cab electrical cabinet are connected through the wire pressing terminal.

Furthermore, the sound and light alarm device mainly comprises a terminal strip, a circuit breaker, a DC-DC conversion module and a control module, wherein DC110V control signals introduced from a vehicle respectively enter the circuit breaker and the DC-DC conversion module through the terminal strip, come out of the DC-DC conversion module and enter the control module, and drive indicator lamps through the control module according to the types of different signals to display different states.

Furthermore, a service brake applying indicator lamp, an emergency brake power supply monitoring indicator lamp, a direct current bus voltage monitoring indicator lamp and a detection module working power supply indicator lamp are arranged on the audible and visual alarm device, and respectively correspond to service brake release abnormity, emergency brake release abnormity, direct current bus undervoltage and audible and visual alarm device faults, and the state of the vehicle can be judged according to the states of the indicator lamps and the buzzer.

The utility model integrates a whole set of brake system monitoring scheme, and the service brake release loop line, the emergency brake positive line, the 110V positive line and the 110V negative line are connected with the acousto-optic alarm device through the special loopback connector to respectively monitor whether the service brake state, the emergency brake state and the loopback power supply work normally or not. When abnormality occurs, the sound-light alarm device gives an alarm, workers in the vehicle are returned to be in contact with a driver, and the fault is processed in the parking process. The problem of vehicle friction wheel, full row wheel pair locking has effectively been solved, the very big loss that reduces traffic accident and conflagration and cause.
