Description

Technical Field

[0001] The invention mainly relates to the technical field of subway platform door control, in particular to a portable single-track platform door cycle switch door controller. Background Art

[0002] In order to ease the traffic congestion problem, many cities have built underground transportation networks, and the subway has become the main means of transportation for people. The fundamental task of subway train operation is to transport passengers to their destinations safely, punctually and comfortably. Due to the advantages of subway trains such as high speed, low interference, energy saving and reduced pollution, they have attracted widespread attention from passengers. They are often crowded and have large passenger flow, so the safe operation of the subway is highly valued.

[0003] The safe operation of the subway has become the most important issue. The subway door control system is most closely related to the passengers. Once a fault occurs in its controller, the door control fails or responds slowly, which will affect the normal operation of the subway and even cause a major accident. During the maintenance or fault handling of the subway single-track platform door, the single-track platform door is tested by circulating the switch. Compared with the existing manual switch, it has higher work efficiency and is easier to find problems with the platform door. Therefore, the utility model provides a portable single-track platform door circulating switch door controller. Summary of the invention

[0004] In order to solve the problems of the prior art, the present invention provides a portable single-track platform door cycle opening and closing door controller.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A portable single-channel platform door cycle switch door controller, characterized in that it includes a control box, a dual-channel delay relay, a passive relay group, a DC24V power supply and a DCU wiring terminal.

[0007] The control box includes four gears: circulation gear, 0 gear, door closing gear, and door opening gear. The angle between each gear is 90 degrees, and each gear is interlocked. Except for the circulation gear and the door opening gear, which cannot be reached by directly rotating 90 degrees, the other gears can be reached by rotating 90 degrees clockwise or counterclockwise.

[0008] The dual-circuit time delay relay realizes the energization and action of the two relays KT1 and KT2 at the specified time by setting the corresponding program.

[0009] The passive relay group includes a door opening relay and a door closing relay. The passive relay group corresponds to the output ends of KT1 and KT2 connected to the dual-circuit delay relay respectively. When the passive relay is energized, the normally open contact is energized.

[0010] The DCU terminal is an interface for controlling the movement of a single-track platform door and is directly connected to the controlled platform door.

[0011] The control box can realize the one-button cyclic door opening and closing function, and also includes single manual door opening and closing. By adjusting the control box to the door opening position, the single-track platform door can be manually triggered to open. By adjusting the control box to the door closing position, the single-track platform door can be manually triggered to close.

[0012] After the dual-channel time delay relay is powered on, the KT1 relay works for A seconds and then disconnects, stops for B seconds, the KT2 relay starts working for C seconds and then disconnects, stops for D seconds, and the cycle is repeated according to the above logic.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] A combination of single door opening and closing and cyclic automatic door opening is adopted. Manual door opening and closing is achieved by manually adjusting the gear position of the control box. The cyclic automatic door opening and closing mode is achieved by setting the corresponding program through the dual-way delay relay, and the door controller automatically opens and closes the door through delay, thereby continuously cycling the corresponding door opening and closing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is the electrical schematic diagram of the portable single-track platform door cycle switch door controller of the utility model. DETAILED DESCRIPTION

[0016] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0017] like Figure 1 As shown, a portable single-channel platform door cycle switch door controller includes a control box, a dual-channel delay relay, a passive relay group, a DC24V power supply and a DCU wiring terminal.

[0018] The control box includes four gears: cycle gear, 0 gear, door closing gear, and door opening gear. The angle between each gear is 90°, and they are interlocked. That is, in any gear, only the preset function of the gear is executed, and the other three gears do not have any effect. Except for the cycle gear and the door opening gear, which cannot be reached by directly rotating 90°, the other gears can be reached by rotating 90 degrees clockwise or counterclockwise.

[0019] The dual-channel time-delay relay sets the corresponding program to realize the power-on action of the two relays KT1 and KT2 at the specified time. When the KT1 relay is energized, it triggers the single-track platform door to open; after KT1 loses power, KT2 is energized, triggering the single-track door to close, and this cycle is repeated to realize cyclic switching.

[0020] The passive relay group is connected to the output terminals of KT1 and KT2 of the dual-channel time delay relay. When the passive relay is energized, the normally open contact is closed.

[0021] The DCU terminal block is the interface for controlling the movement of single-track platform doors and is directly connected to the controlled platform door.

[0022] Furthermore, the control box can realize the one-button cyclic door opening and closing function, and also includes single manual door opening and closing. By adjusting the control box to the door opening position or the door closing position, the single-track platform door can be manually triggered to open.

[0023] Furthermore, after the dual-channel delay relay is energized, the KT1 relay works for A seconds (giving a door opening signal) and then disconnects, stops for B seconds, and the KT2 relay starts working for C seconds (giving a door closing signal) and then disconnects, stops for D seconds, and the cycle is repeated according to the above logic.

[0024] Specifically, Figure 1 In the figure, × indicates the conduction of the switch. In the cycle position, ① and ②, ⑨ and ⑩ are turned on. and conduction; in the 0 gear position, ③ and ④ are conducted; in the door closing gear position, ⑤ and ⑥ are conducted, ⑨ and ⑩ are conducted, and When the door is open, ⑦ and ⑧ are connected, ⑨ and ⑩ are connected, and Conductivity.

[0025] Steps:

[0026] The control box is in the 0 position by default. Connect the DCU terminal to the DCU door machine controller of the controlled single-track platform door, and adjust the control box to the cycle position. At this time, the DC24V power supply completes the power supply to the dual-channel delay relay.

[0027] 1. The dual-channel time delay relay starts working, KT1 is energized, and the energization holding time is adjustable. At this time, KT2 is not energized, and the door opening relay of the passive relay group is energized, so that its normally open contact is attracted, and the ⑧ and Conductive, triggering the single-track platform door to open.

[0028] 2. After the KT1 power-on time is over, KT1 is de-energized, KT2 is energized, and the power-on holding time is adjustable. The closing relay of the passive relay group is energized, so that its normally open contact is attracted, and ⑦ and Conductive, triggering the closing of the single-track platform door.

[0029] The dual-channel delay relay has a built-in program that can automatically cycle through the first and second steps to achieve one-button cycle door opening and closing. In addition to the one-button cycle door opening and closing function, the control box is also set to single manual door opening and closing. Taking single manual door opening as an example, adjust the control box to the door opening position. At this time, ⑦ and ⑧ on the control box are connected. After connection, ⑧ and ∫ on the DCU terminal block are connected. Conductive, triggering the single-track platform door to open.

[0030] While the apparatus described and illustrated is highly effective in carrying out the objects of the invention, it should be understood that the embodiments described are merely examples and that numerous modifications in construction details and design are possible, as will be apparent to those skilled in the art, without departing from the broader scope and spirit of the invention.
