Embodiment 1

[0064] A safety protection device for full-height screen doors, such as figure 2 As shown, the safety protection device 2 is installed on the door frame 3 of the screen door, located at the position of the door leaf 1, and fixed at the top leftmost end of the door leaf 1. Such as figure 1 As shown, the safety protection device 2 includes: a laser emitting device, a laser deflection device, an optical signal receiving device, and an analysis and processing device. Wherein, the laser emitting device emits a directional laser signal to the laser deflection device. The laser deflection device deflects the directional laser signal to a preset angle under the control of the analysis and processing device, and forms a laser scanning sector 4 . The optical signal receiving device is used for receiving the returned laser signal and transmitting the signal to the analyzing and processing device. The analysis and processing device includes: a laser deflection control module, a trigge...

Embodiment 2

[0067] A safety protection device for a full-height shielded door, the safety protection device 2 is installed on the door frame 3 of the shielded door, located at the position of the door leaf 1, and fixed at the top leftmost end of the door leaf 1. Such as figure 1 As shown, the safety protection device 2 includes: a laser emitting device, a laser deflection device, an optical signal receiving device, and an analysis and processing device. The analysis and processing device includes: a laser deflection control module, a trigger distance analysis module, a scanning area adjustment module and a scanning signal analysis module. Such as image 3 As shown, the safety protection device 2 uses itself as a base point to form a laser scanning sector 4 in the shape of a quarter-circle sector with one side horizontal and the other vertical. The scanning area adjustment module includes the following analysis steps:

[0068] S1. Scan in a safe environment.

[0069] S2. Record the dis...

Embodiment 3

[0072] A safety protection device for a full-height shielded door, the safety protection device 2 is installed on the door frame 3 of the shielded door, located at the position of the door leaf 1, and fixed at the top of the door leaf 1 near the left end. Such as figure 1 As shown, the safety protection device 2 includes: a laser emitting device, a laser deflection device, an optical signal receiving device, and an analysis and processing device. The analysis and processing device includes: a laser deflection control module, a trigger distance analysis module, a scanning area adjustment module and a scanning signal analysis module. Such as Figure 4 As shown, the safety protection device 2 uses itself as a base point to form a fan-shaped laser scanning sector 4 that is horizontal on one side and forms an angle with the door frame 3 on the other side. The central angle of the laser scanning sector 4 is 110°. The scanning area adjustment module includes the following analysis ...

Abstract

The invention provides a safety protection device used for a full-height safety door and aims to overcome defects in the prior art. The safety protection device comprises a laser emitter, a laser deflector, a laser signal receiver and an analyzing and processing unit, wherein the laser emitter emits a directional laser signal to the laser deflector; the laser deflector is used for deflecting the directional laser signal by a preset angle and forming at least one laser scanning sector; the laser signal receiver is used for receiving a returned laser signal; the analyzing and processing unit comprises a trigger distance analyzing module, a scanning zone adjusting module and a scanning signal analyzing module; the trigger distance analyzing module is used for analyzing distance information of the distance between a trigger point and a safety protection device body; the scanning zone adjusting module is used for adjusting the zone contour generating an effective feedback signal in the laser scanning sectors; and the scanning signal analyzing module forms a safety door control signal according to the trigger point distance information obtained by the trigger distance analyzing module.

Description

technical field [0001] The invention belongs to the technical field of automatic door sensors, and in particular relates to a safety protection device for a full-height shielded door. Background technique [0002] In recent years, with the continuous progress of the urbanization process, the pressure on urban traffic is increasing, leading to more and more cities choosing to use rail transit to relieve the necessary traffic pressure. Among them, the subway is a common urban rail transport. Compared with traditional rail transit vehicles such as trains, bullet trains, and high-speed rails, since subways are often built underground, and passengers are often waiting on the platform before the train enters the station, and the number of subway passengers is often large, it is easy to be crowded due to platform congestion. Thus causing safety accidents. Therefore, screen doors with safety protection functions need to be equipped on subway platforms, some bullet trains, and high...
