The method for controlling the opening and closing of the subway door in the embodiment is described below, and specifically comprises the following steps:

When the subway stops, the sliding motor 39 starts to rotate forward to drive the rotating shafts 31 at two sides to rotate synchronously, the sliding block 40 is driven to slide far away from the sliding motor 39 through threaded connection, the sliding block 40 drives the movable plate 19 to slide through fixed connection, the movable plate 19 can drive the subway door 11 to slide through the fixed shaft 18, and at the moment, the subway door 11 at two sides slides far away from the sliding motor 39 until the subway is opened. Here, the right place behind the subway door 11 is a passenger getting-off area in the subway, the waiting areas of getting-on subway passengers are arranged on two sides of the getting-off area, the front of the subway door 11 is a subway carriage correspondingly, the opening of the pressure cavity 20 faces the getting-off area, the passengers needing to wait for riding wait for getting-on in the waiting area, and the passengers waiting for getting-off wait for getting-off in the carriage.

And the step of unlocking the subway door, namely when the subway door 11 slides, the electromagnet 38 is started, the magnet 30 is driven to slide through magnetic connection, and then the locking block 29 is driven to slide into the cavity 36 through fixed connection and is in a state of being separated from the inner wall of the locking cavity 28, and at the moment, the movable plate 19 and the subway door 11 are unlocked. Here, the first contact switch 34 is in contact with the second contact switch 35 but does not cause the electromagnet 38 to stop operating because the electromagnet 38 is forcibly activated.

The subway door 11 slides, the spur gear 21 is driven to slide through the fixed connection, after the spur gear 21 slides to be contacted with one end face, close to the rack cavity 22, of the rack 24 when being meshed with the rack 24, the outer circular face of the spur gear 21 is meshed with one end face of the rack 24, when the spur gear 21 continues to slide, the spur gear 21 can be driven to rotate through the gear meshing, the spur gear 21 drives one end, close to the sliding motor 39, of the subway door 11 to rotate towards the lower car area through the fixed connection until the subway doors 11 on two sides are unfolded in an eight shape, the wide openings of the subway doors on two sides face into a carriage, the narrow openings face into the lower car area, and passengers in the subway can get off conveniently. Here, when the subway door 11 slides, the spur gear 21 may be driven to slide through the fixed connection, and when the spur gear 21 moves to the position just before being meshed with the rack 24, the electromagnet 38 is started to unlock the movable plate 19 from the subway door 11.

When the subway door 11 slides, the telescopic motor 15 starts to rotate positively, the telescopic motor 15 drives the threaded shaft 16 to rotate, and then the telescopic plate 13 is driven to slide far away from the corresponding telescopic motor 15 through threaded connection, the first contact switch 34 is separated from the second contact switch 35, after the telescopic plate 13 slides to the maximum distance, the telescopic motor 15 stops rotating, at the moment, the two side telescopic plates 13 reduce the getting-off area, passengers waiting for getting off in the middle get off the subway are prevented from getting on the subway at the same time, confusion is caused, meanwhile, the telescopic plate 13 slides to drive the pressure plate 26 to slide, after the pressure plate 26 slides out of the extension cavity 12, the pressure plate 26 is not pressed by the inner wall of the extension cavity 12, at the moment, the compression spring 27 drives the pressure plate 26 to slide far away from the distance sensor 25 through self elasticity, the distance sensor 25 starts to detect the distance between the pressure plate 26, when passengers in the subway get off the subway, the passengers waiting for getting on the subway at the same time are crowded, the passengers can contact the pressure plate 26 firstly to press the pressure plate 26 into the pressure cavity 20, when the passengers get on the subway at the crowded subway, the passengers enter the subway, the distance is larger than the preset value, the distance is equal to the preset, and the voice signal is sent to the terminal order is kept downwards, and the passengers can send out, and the voice signal is sent downwards by the passengers; when the extension plate 13 moves to the maximum distance, after a period of time, the telescopic motor 15 is reversed to drive the extension plate 13 to reset, after the extension plate 13 is reset, the area between the subway doors 11 on both sides is enlarged, at the moment, the phenomenon of subway congestion is relieved when the subway is opened, the larger area between the subway doors 11 on both sides is convenient for passengers to get on and off the subway at the moment, the efficiency is improved.

When the subway door 11 is to be closed, the sliding motor 39 is reversed to drive the subway door 11 to slide and reset in the direction approaching to the sliding motor 39, when the spur gear 21 passes through the rack 24 again, the spur gear 21 rotates and drives the subway door 11 to rotate to reset, at the moment, the first contact switch 34 and the second contact switch 35 are propped against each other, the electromagnet 38 can be controlled to stop working, the locking spring 37 drives the locking block 29 to slide into the locking cavity 28 through self elasticity and locks the subway door 11 and the movable plate 19, and after the sliding block 40 slides to reset, the adjacent end faces of the subway doors 11 at two sides are propped against each other, so that closing is completed.

Referring to fig. 7, two ends of the pressure plate 26 near the side of the compression spring 27 are fixed with guide plates 41, the guide plates 41 are slidably connected with the pressure chamber 20 and cover the compression spring 27 therein, so that the pressure plate 26 cannot completely extend out of the pressure chamber 20 to cause abnormal resetting, and the function of guiding and protecting the compression spring 27 is also achieved.

When the subway door (11) slides, it rotates outwards driven by the rack mechanism until the subway doors (11) on both sides are unfolded in an "eight" shape, with the wide openings of the subway doors (11) on both sides facing the carriage and the narrow openings facing the getting-off area. When the subway door (11) slides, the extension plate (13) slides outwards of the subway door (11). When the extension plate (13) slides to the maximum distance, it stops. At this time, the extension plates (13) on both sides reduce the getting-off area and form a barrier together with the subway door (11) to prevent passengers who get off in the middle from getting off the subway while passengers waiting to get on the train on both sides get on the train at the same time, causing chaos. At the same time, the sliding of the extension plate (13) drives the pressure plate (26) to slide. When the pressure plate (26) slides out of the extension cavity (12), the pressure plate (26) is no longer pressed by the inner wall of the extension cavity (12). At this time, the compression spring (27) drives the pressure plate (26) in a direction away from the distance sensor (25) through its own elasticity. The distance sensor (25) starts to slide and begins to detect the distance between the distance sensor (25) and the pressure plate (26). When passengers in the subway get off the subway, passengers waiting to board the subway outside get on the subway at the same time, causing congestion. When the passengers get on the subway, the passengers will first contact the pressure plate (26) and then drive the pressure plate (26) to be pressed into the pressure chamber (20). When the distance that the pressure plate (26) slides into the pressure chamber (20) is greater than a preset value, the distance sensor (25) sends an electrical signal to the terminal, and then the subway station can make a sound or prompt the passengers to get off and then get on through staff to maintain order. When the extension plate (13) moves to the maximum distance, after a period of time, the extension plate (13) is reset. After the extension plate (13) is reset, the area between the subway doors (11) on both sides becomes larger. At this time, the congestion phenomenon of getting on and off the subway and the subway door opening is much relieved. The larger area between the subway doors (11) on both sides is convenient for passengers to get on and off the subway at this time.
