Problems solved by technology
[0005] The present invention proposes a control system for the air valve of a subway vehicle. Before the door needs to be closed, the fresh air volume is reduced, so that the air pressure in the car is kept at a low level, thereby ensuring that the door can be closed normally; after the door is closed, the fresh air volume and The pressure in the car returns to normal level, which solves the problem that a single door cannot be closed normally when the positive pressure in the car is high

Embodiment 1
[0015] as attached figure 1 The control system for the air-conditioning air valve of a subway vehicle is shown, including a central control unit, a load sensing unit, an air-conditioning control unit, and a door control unit. The central control unit controls the operation of the entire vehicle system and sends a door-opening command to the air-conditioning control unit At the same time, the door opening and closing instructions are sent to the door control unit; the door control unit is connected to the central control unit, receives and executes the door opening and closing instructions from the central control unit, and sends the information that the doors have been opened and that all the doors have been closed The information sent to the air-conditioning control unit; the load sensing unit senses the weight of the passenger, and sends the sensed passenger weight to the air-conditioning control unit; the air-conditioning control unit is connected to the central control unit...

The invention belongs to the field of electric control design for rail transit vehicle air conditioner control units and relates to a control system of a subway vehicle air conditioner air valve. According to the control system, an air conditioner control unit is connected with a central control unit and a vehicle door control unit, the central control unit transmits a door opening command to the air conditioner control unit while transmitting the door opening command to the vehicle door control unit, the opening degree of a fresh air valve is decreased when the air conditioner control unit receives the door opening command transmitted by the central control unit, and after the information which is transmitted by the vehicle door control unit and indicates that all vehicle doors are closed is received, the opening degree of the fresh air valve is adjusted again according to the passenger weight induced by a load induction unit; and the vehicle door control unit is connected with the central control unit and receives and executes the door opening command and door closing command transmitted by the central control unit. By the adoption of the technical scheme, the requirement for fresh air amount at the positive pressure can be met while the requirement for fresh air amount is met.
Description
technical field [0001] The invention belongs to the field of electrical control design of an air-conditioning control unit of a rail transit vehicle, and relates to a control system for an air-conditioning air valve of a subway vehicle. Background technique [0002] The air conditioning control unit is a complex coupling system. In subway vehicles, the fresh air valve is mainly used to control the amount of fresh air entering the car. At present, the opening is usually adjusted according to the load, that is, the opening is large when there are many people, and the opening is small when there are few people. The opening does not change when the load does not change. In subway vehicles, it is generally required that the positive pressure inside the car be controlled between 30 and 50 Pa. The reason is to ensure the normal closing of the doors; It was mistakenly believed that there was an obstacle and could not be closed normally. On subway vehicles, there is an inseparable ...
