As shown in fig. 5, the controller controls, for the second period of time, to turn off all the laser transmitters and the light receivers, when the red light is turned on, all the laser transmitters and the light receivers are turned on, the controller controls, under the condition that the red light is in a lighting state, when more than one light receiver does not receive the light signal of the laser transmitter (indicating that a person (or an article) stands on the bottom plate at the moment), the sound prompt device sends prompt information (the prompt information is, for example, "please go backwards, do not need to cross the stop line", thereby urging the pedestrian to go backwards, if the pedestrian goes backwards, all the light receivers can receive the signal, corresponding operation is carried out, if the pedestrian does not go backwards, the prompt information is sent out all the time, and the first telescopic rod and the second telescopic rod do not extend, so that the first elastic rope and the second elastic rope are prevented from catching the pedestrian); under the condition that the red light is in a lighting state, when all the light receivers can receive light signals of the laser transmitters (no pedestrian exists on the surface of the bottom plate), all the laser transmitters and the light receivers are turned off, and the first electric telescopic rod and the second electric telescopic rod are extended from the shortest state to the longest state (the first electric telescopic rod and the second electric telescopic rod are extended to further confirm whether the person exists in the first electric telescopic rod or not according to the measured value of the tension sensor, and when the measured value of the tension sensor is smaller than a set threshold value, the fact that the person does not exist is indicated); under the condition that the first electric telescopic rod and the second electric telescopic rod are both in the longest state, when the measured value of the tension sensor is larger than or equal to a set threshold value (indicating that a person is at the bottom plate at the moment, the situation rarely occurs, although no person is judged according to the signal of the light receiver, the light receiver judges only one point after all, and the judgment is not completely accurate), the sound prompting device sends prompting information, when the measured value of the tension sensor is smaller than the set threshold value (further confirmation is carried out at the moment, no person is at the position corresponding to the first electric telescopic rod and the second electric telescopic rod, and the width of the horizontal groove is very narrow, so that when the position of the first electric telescopic rod and the position of the second electric telescopic rod are not at the moment, no person is at the position of the first vertical guide rod and the position of the second vertical guide rod basically, the first motor and the second motor are controlled to.
Through foretell mode to the realization stops pedestrian's red light of running through when the red light. This is very effective when the red light is on and the pedestrian is not crossing the stop line. Although when the red light is on, people always cross the stop line and stand on the bottom plate, the stay cord cannot be lifted, and the effect of stopping running the red light is poor. But also avoids the pedestrian being scraped by the pull rope when the pull rope is pulled up. The first and second sliders can be lowered by paying off the first and second winding devices together, and the first and second sliders can be raised by taking up the first and second winding devices together.
When the green light is on, if the first electric telescopic rod and the second electric telescopic rod are in the shortest state, the first electric telescopic rod and the second electric telescopic rod are kept in the shortest state, and if the first electric telescopic rod and the second electric telescopic rod are in the non-shortest state, the first electric telescopic rod and the second electric telescopic rod are restored to the shortest state; when the green light is on, if the first sliding block and the second sliding block are at the lowest positions, the first sliding block and the second sliding block are kept at the lowest positions, and if the first sliding block and the second sliding block are not at the lowest positions, the first sliding block and the second sliding block are restored to the lowest positions.
By the arrangement, when the green light is in a green state, the stretching rope and the elastic rope are located in the horizontal groove, so that normal passing of pedestrians is not affected.
While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined in the following claims.
