The electromagnet A157 is powered off and does not adsorb the counterweight iron rod 156. The sleeve 155 falls under gravity. The counterweight iron rod 156 pulls the sleeve 155 to make the display cloth 154 rotate out of the roller 151.

The ultrasonic transmitting end 232 on the ultrasonic sensor 23 sends an ultrasonic signal to detect the person. Positioning, the ultrasonic receiving end 233 receives the ultrasonic reflection signal, and then locates the position of the person according to the ultrasonic reflection signal. Because the entering people usually wear shoes, the shape and outline of the shoes are roughly the same, which is used to distinguish between luggage and pedestrians. The infrared sensor monitoring device 13 detects the pedestrian entry signal and transmits it to the main controller 4 through the signal line 3. The ultrasonic sensor 23 detects the pedestrian positioning signal and transmits it to the main controller 4 through the signal line 3. The main controller 4 collects and processes the information in a centralized manner, and then knows the number of pedestrians entering the area and their positioning positions, and then adds up the number of people in all areas to complete the passenger flow monitoring.

[0039] The diversion assembly 25 includes a hydraulic rod 251, a diversion baffle 252, a contact switch 253, a warning sticker 254 and a voice prompter 255.

When in normal use, when a person or luggage is directly above the warning sticker 254, the contact switch 253 is triggered, so that the voice prompter 255 sounds an alarm to remind the person or luggage to stay away from the contact switch 253 to avoid the diversion baffle 252 from hitting the luggage or pedestrians when it rises.

[0040] Working principle:

[0041] When the device is in use, the upper mounting frame 11 is installed on the top of the station through the support assembly 12, and the adjacent upper mounting frames 11 are docked and limited by the positioning blocks 121, and then the placement frame 123 is inserted into the inner side of the two upper mounting frames 11, and the threaded rod 125 is screwed into the installation card 122 so that the threaded rod 125 passes through the positioning groove of the placement frame 123 and enters the card groove of the upper mounting frame 11, and then the support assembly 12 is fixed to the top of the station, and then the assembly frame 143 is placed on the inner side of the upper mounting frame 11, the bracket A141 is aligned with the installation groove A, and the bracket B142 is aligned with the installation groove B, and the bracket A141 and the bracket B142 support the assembly frame 143. The lower monitoring mechanism 2 is laid on the surface, and a fixed groove is pre-opened on the ground for placing the hydraulic rod 251 and the diverter baffle 252. The upper mounting frame 11 is installed and aligned with the lower mounting frame 21. The area of ​​a lower mounting frame 21 is a separate area. When entering an area, the infrared sensor monitoring device 13 can detect whether someone has entered the corresponding area. The ultrasonic transmitting end 232 on the ultrasonic sensor 23 sends out an ultrasonic signal to locate the person, and the ultrasonic receiving end 233 receives the ultrasonic reflection signal, and then locates the person according to the ultrasonic reflection signal. Because the entering person generally wears shoes, the shape and contour of the shoe are roughly the same, which is used to distinguish between luggage and pedestrians.

[0042] The infrared sensor monitoring device 13 detects the pedestrian entry signal and transmits it to the main controller 4 through the signal line 3. The ultrasonic sensor 23 detects the pedestrian positioning signal and transmits it to the main controller 4 through the signal line 3. The main controller 4 collects and processes the information in a centralized manner, thereby knowing the number and positioning positions of pedestrians entering the area, and then adding up the number of people in all areas to complete the passenger flow monitoring.

[0043] When a fire or terrorist attack occurs, the infrared sensor monitoring device 13 and the ultrasonic sensor 23 are combined to monitor personnel, so as to determine whether there are still pedestrians in a certain area. The main controller 4 calculates that when a fire or terrorist attack occurs, the hydraulic rod 251 rises and pushes the diversion baffle 252 to rise, the electromagnet A157 is powered off and does not adsorb the counterweight iron rod 156, the sleeve 155 falls due to gravity, the counterweight iron rod 156 pulls the sleeve 155 to make the display cloth 154 rotate out of the roller 151, and the electromagnet B26 adsorbs the counterweight iron rod 156 and the sleeve 155 to prevent the display cloth 154 from moving around at will. At this time, the two display cloths 154 are facing outward, and then auxiliary instructions are given, and diversion and evacuation are carried out according to the guidance on the display cloth 154, so as to achieve rapid dispersion and unblocking of the flow of people.

[0044] During normal use, when a person or luggage is directly above the warning sticker 254, the contact switch 253 is triggered, causing the voice prompter 255 to sound an alarm, reminding the person or luggage to stay away from the contact switch 253 to prevent the diverter baffle 252 from hitting the luggage or pedestrians when it rises. When a fire or terrorist attack occurs and needs to be reset, the electromagnet A157 is energized, the counterweight iron rod 156 is placed between the electromagnets A157 to complete the adsorption and fixation, and the clockwork spring 152 drives the roller 151 to reset and rewind the display cloth 154.
