[0028] See also Figure 1 and Figure 4 As shown, a pedestrian detection device, a dangerous area alarm component 3, includes an infrared sensor 301, a telescopic shell 302, a telescopic inner core 303, a power supply 304, a rotating piece 305, a control power supply 306, and an alarm 307.

[0030] Working principle: First, install the device at the waiting place on the roadside. When a person comes to the device and waits for the green light to pass, the infrared transmitter 201 is always emitting infrared rays. When the corresponding infrared receiver 208 does not receive the signal, it is blocked by the person, and it can be understood whether there are people who need to cross the road. At this time, this information will be transmitted to the traffic light system. When the number of waiting people reaches a certain level or after waiting for a period of time, the system will control the pedestrian traffic light to turn green to let the person pass. When the person is waiting for the green light, the protective cover 203 will provide a protective function to prevent the person from accidentally touching the infrared transmitter 201. The infrared transmitter 201 and the infrared receiver 208 are damaged, and the protective cover 203 can be rotated so that personnel can inspect and repair the infrared transmitter 201 and the infrared receiver 208. In addition, when a large amount of dust is stained on the protective cover 203, it will affect the normal operation of the infrared transmitter 201 and the infrared receiver 208 to a certain extent. At this time, the control rod 205 can be operated to make the connecting block 206 carry the cleaning sheet 207 to clean the surface of the protective cover 203. The cleaning sheet 207 is connected to the connecting block 206 by Velcro. When the cleaning sheet 207 is too dirty, it can be disassembled for cleaning or replaced;

[0031] Next, when a person is waiting for the green light in the device, if the person is too close to the road, the infrared sensor 301 will sense it. At this time, the infrared sensor 301 will transmit in the form of an electrical signal, so that the telescopic inner core 303 extends from the telescopic outer shell 302, and pushes the rotating piece 305 to rotate around the power supply 304 and touch the control power supply 306. The power supply 304 can provide electrical energy, and the control power supply 306 is electrically connected to the alarm 307. At this time, the circuit of the alarm 307 can be connected, and the alarm 307 starts to work and sounds an alarm to remind the person to pay attention to safety. Then, when the person is waiting for the green light at this place on a rainy day, When the solar panel 404 is installed, the solar panel 404 can be shielded to prevent the rain from falling on people. At the same time, on sunny days, the solar panel 404 can provide electricity for the components in the device, and the angle of the solar panel 404 can be adjusted. The angle of the solar panel 404 can be adjusted by rotating the rotating ball 403. Therefore, the angle of the solar panel 404 can be controlled according to the actual situation of the installation site, so that the solar panel 404 can irradiate more solar energy. Then, after the angle of the solar panel 404 is adjusted to a suitable level, tighten the threaded locking rod 402 so that one end of it is against the rotating ball 403, and the angle of the solar panel 404 can be fixed.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
