Description

Anti-trailing brake device

This creation is about a passage blocking device, and more particularly, a trailing brake device.

The gate is a kind of channel blocking device (channel management equipment). It is used to manage the flow of people and regulate pedestrian access. It is mainly used in subway gate systems and toll gate systems. The most basic and core function of the gate is to realize that it can only be used by one person at a time, and can be used at the entrance channel of various toll collection and access control occasions. The gate is used to identify the passing state of the pedestrian, determine whether the pedestrian is legally passing, and can determine whether the pedestrian is within the movement range of the blocking body to protect the pedestrian's personal safety.

In order to improve the accuracy of detection, high-end gates will use more than 10 pairs of imported infrared photoelectric switches. Special occasions will use high-performance infrared light curtains or other special sensors, which often results in expensive gate manufacturing and use costs. In addition, different recognition algorithms need to be set according to the pedestrian height, step distance, speed, and the size and location of the luggage carried. Gate manufacturers need to establish corresponding mathematical models based on a large amount of experimental data and develop their own identification algorithms, which increases the complexity and time of gate development. In addition, if more than one person passes the gate continuously, a trailing situation is likely to occur. The gate manufacturer often needs to set up a more accurate sensor or a more complicated algorithm, which increases the difficulty of research and development of the manufacturing cost of the gate.

Application scenario 1: When no passenger passes the gate:

The front door and the back door are closed, and the grating and the photocoupler are not blocked by any opposing light spots, and the detection area is idle.

Application scenario 2: When a passenger passes the gate without luggage:

(1) Passengers need to enter the detection area stage: When a passenger passes the front grating Z5, the front grating Z5 has light spots blocked, indicating that someone needs to enter the detection area. Front door 2 and rear door 3 are opened to allow passengers to enter the detection area.

(2) Passengers enter the detection zone stage: Specifically, suppose that the height of normal passersby is more than 1.4 meters, and the area that blocks the middle raster Z234 is the ankle part below the knee. The area is above the chest. The middle grating Z234 and the upper handrail grating Z6 use a measuring light curtain with a light spot spacing of 8cm. The width of the wings of the front door 2 and the rear door 3 is 30cm. The middle grating Z234 detects that at least one light spot is blocked, and the object blocking the light spot is displaced to a position more than 30 cm (or other distance) from the door wing of the front door 2, the front door 2 is closed, and it is determined that the passenger has entered the detection area.

(3) Passenger leaving the detection area: When the passenger leaves from the rear door 3, after no light spot is blocked in the middle grating Z234 and the rear grating Z1, the rear door 3 is closed.

Application scenario 3: When two passengers pass through the gate:

(1) Passengers need to enter the detection area stage: same as (1) in application scenario 2.

(2) The passenger enters the detection area stage: the middle grating Z234 detects that there are two occlusion areas, plus more than one transmission point, plus another occlusion area, and the upper handrail grating Z6 also detects that there are two occlusion areas, plus more than one The transmission point, plus a blocking point, indicates that at least two columnar objects pass through with a gap, and a trailing alarm is issued.

Application scenario four: a passenger with a backpack:

The difference from application scenario two is that the backpack can only affect the upper handrail grating Z6 to detect that more than two light spots are blocked, while the middle grating Z234 does not have more than two blocked areas blocked.

Application scenario five: a passenger with a tow box:

The difference from application scenario two is that the drag box can only affect that the middle grating Z234 detects that more than two light spots are blocked, while the upper handrail grating Z6 does not block more than two light spots.
