Embodiment Construction

[0015] Embodiments of the present invention will be explained below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the waste discharge linkage circuit of the present invention, the waste discharge power supply circuit and the waste discharge and fire detection linkage circuit.

[0017] Wherein, the waste discharge power supply circuit includes a waste discharge power supply circuit breaker AP, a waste discharge power supply AU, a normally closed contact FRC1 of the first fire alarm detection closing relay, a normally closed contact FRC2 of the second fire alarm detection closing relay and a waste discharge device AD . One end of AP of the waste power supply circuit breaker is connected to the positive pole of the power supply DC110V, and the other end is connected to the positive pole of the waste power supply AU input terminal; the negative pole of the waste power supply AU input terminal is connected to the power supply negative pole DC11...

Abstract

The invention relates to a waste discharge linkage circuit based on rail vehicle fire smoke detection. The waste discharge linkage circuit comprises a waste discharge power supply, a waste discharge device connected with the waste discharge power supply, a fire alarm controller, an in-vehicle fire smoke detector connected with the fire alarm controller, an under-vehicle fire smoke detector and a first fire alarm detection turn-off relay, wherein a normally closed contact of the first fire alarm detection turn-off relay is connected into a circuit between the waste discharge power supply and the waste discharge device in series. Compared with the prior art, the linkage waste discharge device based on a fire smoke detection system can realize that the waste discharge device is not influencedby the environment in the vehicle to close an air door when fire occurs in the vehicle or outside the vehicle; on the contrary, when no fire occurs in the vehicle or outside the vehicle, the waste discharge air door is kept in an open state, so that the air quality of the passenger room under a normal state or an emergency state can be effectively guaranteed, and the riding comfort degree of passengers is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle air conditioning, in particular to a waste discharge linkage method based on fire and smoke detection. Background technique [0002] In rail vehicles, the air-conditioning unit sends air to the compartment through the air supply duct and the air supply outlet, and sends it back to the air conditioner through the return air duct, and the air is recycled. The air conditioning unit delivers fresh air to the compartment through the fresh air outlet to ensure the freshness of the air in the compartment. While inputting fresh air into the cabin, there is a positive pressure in the cabin, and the exhaust device is opened to discharge the exhaust gas in the car and adjust the air pressure in the car. When there is no positive pressure in the car, the damper closes the damper by its own gravity. [0003] At present, most of the exhaust devices on rail vehicles adopt the natural ventilation exhaust m...
