Description

Technical Field

[0001] The utility model relates to the field of tail light strips for subway shielding doors, in particular to a color-changeable tail light strip system for subway shielding doors. Background Art

[0002] With the construction of urban rail transit and the increase in population, it is becoming increasingly convenient to travel by subway. It has brought about an increase in passenger flow, and at the same time, more and more intelligent equipment and automated facilities have been put into actual operations. As one of the equipment that electric train drivers must pay attention to in daily life, the light strip at the tail of the shield door is installed to facilitate the electric train driver to observe the gap between the train and the door. After the electric train driver has completed the platform door opening and closing operation, the last step before entering the cab is to confirm whether the tail light strip between the door and the platform door is complete, to assist the driver in observing whether there is a safety incident of people or objects being caught in the door, or whether there are passengers or items left in the gap. In daily work, it has the characteristics of high frequency of use, great effect, and easy to ignore. Once the driver observes the incompleteness of the light strip, it will have a huge impact on the driving organization, which may cause the train to be delayed at the least, or cause the door or shield door to catch people or objects in the train, resulting in casualties.

[0029] In a specific implementation, the controller uses a universal single-channel circuit board, the purpose of which is to ensure that only one channel is powered in the case of multiple links.

[0030] Embodiment 3, this embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0031] The variable light strip module is a COB-LED light strip.

[0032] Embodiment 4: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0033] The human detection module is an infrared human body detection sensor switch module.

[0034] Embodiment 5, this embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0035] The object detection module is an infrared diffuse reflection sensor switch module.

[0036] Embodiment 6: This embodiment is a further improvement on the basis of embodiment 1, and its details are as follows:

[0037] The proximity start module is an electromagnetic proximity sensor switch module. In the specific implementation, the electromagnetic proximity sensor switch module adopts a three-wire PVP type electromagnetic induction proximity switch module; when the object approaches the proximity switch, a high level is generated on the black signal line, and load 1 is powered on, where load 1 is a "detection of people and objects" module. Specific embodiment:

[0039] The normally closed module is connected to a yellow light strip, which is always on to indicate normal operation, so that the driver can observe the gap between the door and the shield door.

[0040] The close-range start module is installed on both sides of the station platform screen door. When the gap between the left and right platform screen doors is 5 cm, the close-range start module is closed, and the three modules of the detection module, object detection module and variable light strip module are powered and start working.

[0041] When there is no person or object trapped by the doors and shield doors, the gap is safe, and the driver observes that the tail light strip shows a complete yellow light strip;

[0042] When both the car door and the shield door are pinching people or objects, or one of them is pinching people or objects, the gap is unsafe;

[0043] When a person is caught, the circuit of the detection module is closed, the normally closed module is short-circuited, and only a red light strip is displayed, warning the electric train driver not to move the train; the infrared human body detection sensor switch module has an independent circuit, which ensures that in the case of multiple circuits, the "detection" circuit has a higher priority triggering than other circuits;

[0044] When an object is caught, the object detection module starts working, the module is normally closed without short circuit, and the blue light strip is energized and lights up. At this time, the blue light strip and the yellow light strip are cross-arranged LEDs, and integrated into a complete light strip will show green. The driver observes that the tail light strip is an incomplete green light, reminding the driver that the gap is unsafe at this time, there is a foreign object in the gap between the vehicle and the platform, and the vehicle cannot be moved.

[0045] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
