Problems solved by technology

[0003] At present, the conventional subway ventilation device control method adopts simultaneous control of multiple actuators to simultaneously open the fan blades 4 of all ventilation units. Although this control method can save time, it has high requirements on the power supply system and cables, which increases the The cost of equipment, while the power will cause a large loss in the transmission process, increasing the operating cost

Embodiment 1

[0022] Embodiment one: a kind of time-sharing control method of subway screen door ventilation device, such as Figure 1~2 As shown, the ventilation device is located on the upper part of the screen door, and consists of a plurality of ventilation units 3 arranged side by side from left to right, and each ventilation unit 3 is provided with a plurality of fan blades 4 side by side from left to right, And each fan blade 4 is controlled by an actuator (not shown in the figure) to flip open and close;

[0023] The time-sharing control method of the ventilation device includes: first preset a control circuit, such as image 3 As shown, the control circuit includes a main control unit and a plurality of sub-control units; wherein, the main control unit is electrically connected with a plurality of sub-control units, and each sub-control unit is connected with a plurality of actuators in the ventilation unit 3 electrically connected to form a tertiary control circuit;

[0024] Whe...

Embodiment 2

[0036] Embodiment two: the difference with embodiment one is:

[0037] Wherein, when one of the actuators under one of the sub-control units completes the opening action corresponding to the fan blade 4, another actuator under the sub-control unit starts to work again until all the actuators under the sub-control unit are completely opened. After the fan blade 4 works, another sub-control unit starts to work again; that is, only one actuator works in a unit time, and only one fan blade 4 does the opening action;

[0038] Furthermore, the opening action of the fan blades 4 is completed at least twice; the first opening, each actuator works one by one, and all the fan blades 4 are turned over one by one to make them open at an angle; the second opening, Each actuator continues to work one by one, completes turning over all fan blades 4 one by one, and repeats this cycle until all fan blades 4 are fully opened one by one.

Abstract

Disclosed is a time-sharing control method of metro shielded door ventilating device. A ventilating device is arranged at the upper portion of a shielded door. The ventilating device is characterized in that a control circuit is arranged in advance, the ventilating device comprises a main control unit and a plurality of sub-control units, each sub-control unit is electrically connected with a plurality of actuators in a ventilating unit to form a three-step control circuit; when the ventilating device needs to be started, a main control unit of the control circuit sends control signals to each sub-control unit to control each sub-control unit to work; each sub-control unit sends the control signals to each actuator, wherein when one actuator under control of the sub-control unit finishes starting operation of corresponding fan blades, then another actuator under the control of the sub-control unit starts to open; the starting operation of the fan blades can be finished at twice. The time-sharing control method of the metro shielded door ventilating device can lower requirements of a power supply system and a cable, further reduce cost of the device, and at the same time solve the problem that energy consumption is large during operation of the system in the past.

Description

technical field [0001] The invention relates to a subway screen door, in particular to a time-sharing control method for a ventilation device of a subway screen door. Background technique [0002] The structure of the common subway screen door is as follows: figure 1 As shown, it includes a door 1, a partition wall panel 2 and a ventilation device. Wherein, the fan door 1 and the partition wall panel 2 form the main body of the screen door; the ventilation device is located on the upper part of the screen door body, and consists of a plurality of ventilation units 3 arranged side by side from left to right, each ventilation unit 3 A plurality of fan blades 4 are arranged side by side from left to right, and each fan blade 4 is controlled by an actuator to flip open and close (see figure 2 ). The ventilation device of the subway screen door mainly has the following functions: 1. Control and adjust the temperature and humidity in the station; take summer as an example, the...
