The channel gate mechanical system is divided into two parts: the chassis and the movement. As a carrier, the chassis is equipped with a direction indicator, a reading and writing device, an infrared sensor, etc. The main components of the movement include a motor, a frame, a transmission shaft, a gate, and the like;
System working principle 1. Turn on the power, and the system will enter the working state after 3 seconds.
2. When the card reader reads a valid card, the beeper will emit a sweet sound, prompting the pedestrian to read the card successfully; at the same time, the information read from the card will be judged and processed, and an application pass signal will be sent to the main control board. ;
The main control board receives the signals of the card reader and the infrared sensor, and after comprehensive processing, it sends an effective control signal to the direction indicator and the motor, so that the direction indicator turns into the green arrow access flag, if the system is in the normally closed mode at this time. When the motor is running, the limit switch controls the power. 3. The motor turns the angle, the gate opens (in the normally open mode, the motor does not move), allowing pedestrians to pass;
4. After the pedestrian indicates the passage of the passage according to the direction indicator mark, the infrared sensor senses the whole course of the pedestrian passing through the passage, and continuously sends a signal to the main control board until the pedestrian has completely passed the passage;
5. If the pedestrian forgets to read the card or read the invalid card to enter the channel, the system will prohibit pedestrians (for the normally open mode, the gate will be closed; normally closed mode, the gate does not move;), and an alarm will be issued until the pedestrian exits the channel Only when the alarm is released; read the valid card again to allow the passage;
