Embodiment 1
[0028] As shown in Figure 1, the safety barrier includes a horizontally arranged slope or curved anti-stand plate 2, which is made of 1.5-2mm stainless steel or other metal materials, which extends the barrier of the screen door to the direction of the track. The detection function is not convenient for people to stand, especially when one foot steps into the gap interval, it is difficult to prevent passengers from standing in the gap between the train door 6 and the screen door. Preferably, as shown in Figures 2a and 2b, the slope or curved anti-stand plate 2 is hinged to the side of the sliding door 1 near the track through a hinge 21, and a pressure sensor 3 is arranged below it, and the data processing between the pressure sensor 3 and the obstacle detection system The device 4 is connected to send an induction signal to it, and is used to detect whether there are people between the closed screen door and the train door gap, and simultaneously control the switch door. When...
Embodiment 2
[0030] The safety baffle includes metal baffles, rubber baffles or other non-metallic baffles 5 that are arranged on the edge of the sliding door 1 and protrude toward the track direction, so that the obstacle detection function of the screen door extends to the track direction and reduces Gap between train and screen door. In this embodiment, a baffle plate 5 with a height of about 500-2150 mm is vertically arranged on the edge of the sliding door. The size of the baffle plate extending to the track direction is related to the limit requirements, and its shape can be various, as shown in Figure 1 or with The limit curve requires a matching shape or other shapes of the baffle, and the design and installation of the baffle is especially suitable for the installed screen door (because the limit requirement is large, the gap needs to be adjusted or reduced). When the screen door is in the closing process, if the passenger is too close to the sliding door 1, the baffle plate 5 wil...
Embodiment 3
[0032] This embodiment is a combination of Embodiments 1 and 2. The safety stop includes an inclined or curved anti-standing plate 2 and a piezoelectric start sensor 3 located below the inclined or curved anti-standing plate 2, and also includes a metal plate vertically arranged on the edge of the sliding door 1 protruding toward the direction of the track. Baffle, rubber baffle or other non-metallic baffle 5, to further improve safety and reliability.
[0033] Based on the anti-clamping device of the above-mentioned shielded door, the present invention improves the obstacle detection method of the shielded door, as shown in Figure 4, the detection method is realized by the following steps:
[0034] (1) Start the screen door closing procedure;
[0035] (2) Detect whether there is an obstacle during the closing process of the shielded door. If there is an obstacle, the shielded door will stop closing and slide or open freely. Alarm; if there is no obstacle, the screen door is...
