Problems solved by technology

If the train shakes a lot when entering and leaving the station, the light belt and the beams that fix the light belt will scratch the train, causing damage to the train
Moreover, the current light strips do not have an alarm function, which is not conducive to timely detection of faults. In addition, the existing light strips cannot be disassembled, and the replacement method is cumbersome.

Embodiment 1

[0041] The fixed column of the present embodiment is a platform screen door column, which will be described below in conjunction with the accompanying drawings.

[0042] Such as Figure 1 to Figure 9 As shown, the light strip device of this embodiment includes a light strip base 1, a light strip body 2, a light strip controller 3, and three mounting brackets 4 (upper, middle, and lower). Installed in the gap between the screen door of the subway platform and the train, the light strip body 2 includes a plurality of LED illuminants 5, light strip circuits, aluminum profiles 6 and long strip light-transmitting lampshades 7, the light strip body 2 It is detachably fixed on the light strip base 1. There is a connecting line 8 between the light strip body 2 and the light strip controller 3. One end of the connecting line 8 is connected to the light strip body 2, and the other end can be connected to the light strip body 2 along the The upper mounting bracket 4 extends to an open p...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that the fixed column is a specially set lamp strip fixed column on the platform.

Embodiment 3

[0051] Such as Figure 10 and Figure 11 As shown, the main feature of this embodiment is: the first bracket body 12 in the mounting bracket 4 and the lamp holder base 1 form an integrated structure. The advantage of this structure is that the manufacture of the lamp strip base is simpler, and the lamp The overall volume of the body device is smaller.

Abstract

The invention discloses a lamp belt device for detecting foreign matters in a gap between a shielded gate at a metro platform and a train. The lamp belt device comprises a lamp belt body, a lamp belt controller, a lamp belt substrate and a mounting support, wherein the belt lamp controller is connected with the lamp belt body, the lamp belt body is detachably fixed in the lamp belt substrate, and the mounting support adopts a rotary structure; the lamp belt body comprises a plurality of LED (Light-Emitting Diode) light-emitting bodies, a lamp belt circuit, aluminum profile and a long strip-shaped transparent lamp cover; the LED light-emitting bodies comprise various colors of LED light-emitting bodies. Different light colors can be obtained through the combination of different colors, and the various colors of LED light-emitting bodies are controlled by the lamp belt controller, so that the lamp color of the lamp belt body automatically changes on time, false detection when the color of a detected matter is similar to that of the lamp belt can be avoided, and the detection accuracy rate for the foreign matters is improved; due to the mounting support adopting the rotary structure, the train can be prevented from being out of control to violently impact the lamp belt, and the damage of the lamp belt device to the train is reduced.

Description

technical field [0001] The invention relates to an LED light strip device, in particular to a light strip device for detecting foreign matter between a subway platform screen door and a train, and belongs to the field of subway operation safety. Background technique [0002] As the scale of the subway network across the country continues to expand and the passenger flow continues to increase, it is particularly important to ensure the safe and efficient operation of the subway. In order to ensure the safety of passengers, screen doors are installed on most of the subway platforms in China. However, there is still a gap of about 10 centimeters between the subway train door and the platform screen door. If passengers or objects are caught in the gap between the screen door and the train door, it will have a serious impact on the safe operation of the subway. Therefore, before the departure of the subway train, the driver must detect whether there is a foreign object in the g...
