Embodiment Construction
[0032] In order to further describe the technical solution of the present invention, first in conjunction with the accompanying drawings:
[0033] combined with figure 1 , 2 , the subway screen door A5 and the subway screen door B7 are respectively provided with two reflector supports 4 by gluing, the reflector support 4 is L-shaped, and the reflector support 4 is vertical on the subway screen door A5 and the subway screen door B7 Symmetrical distribution, the reflector A2 and the reflector B6 are installed on the reflector bracket 4 on the subway shield door A5 and the subway shield door B7 through rivets, and the reflector A2 and the reflector B6 are installed on one side of the L-shaped reflector bracket 4 side, and this side is close to the side of the ground-fall screen door A5 and the subway screen door B7.
[0034] When the subway screen door A5 and the subway screen door B7 were closed, the mirror distance between the reflector A2 and the reflector B6 was 60cm.

The invention discloses a metro boundary safety detection device based on a laser linear array.The metro boundary safety detection device comprises a laser transmitting terminal, a reflecting mirror A, a reflecting mirror B, a laser receiving terminal, four reflecting mirror supports, a metro shielding door A and a metro shielding door B, wherein the reflecting mirror supports are symmetrically installed on the vertical inner side face of the metro shielding door A and the vertical inner side face of the metro shielding door B and are vertically distributed along the metro shielding door A and the metro shielding door B; the reflecting mirror A and the reflecting mirror B are installed on the reflecting mirror supports, and when metro shielding door A and the metro shielding door B are closed, the distance between the surface of the reflecting mirror A and the surface of the reflecting mirror B is 50-70 cm; the laser transmitting terminal and the laser receiving terminal are installed on the metro shielding door A, the laser transmitting terminal is located at the lower side of the reflecting mirror A, and the laser receiving end is located on the surface of the reflecting mirror A and is close to the upper side edge of the reflecting mirror A; the included angle between the laser transmitting end and the horizontal plane is 2-8 degrees; the laser receiving end is composed of multiple laser receiving tubes arranged perpendicular to the metro shielding door A in parallel.
Description
technical field [0001] The invention relates to an urban rail transit subway station boundary protection system, in particular to a subway boundary safety detection device based on a laser line array. Background technique [0002] With the rapid development of my country's urban rail transit, for the consideration of air-conditioning energy saving and passenger safety, subway platform screen doors are widely used. At the same time, in order to ensure the safe high-speed operation of the subway, a certain gap must be left between the screen door and the car body. This gap is called the boundary. The boundaries of domestic subways are mostly about 30cm. Once the screen doors and subway doors are closed, there will be great safety hazards for passengers staying in the boundaries. [0003] At present, the method to solve this problem is to adopt laser or infrared device and anti-trap baffle to detect whether passengers are stranded (including limb stranded). The traditional la...
