Detailed Explanation Of License Plate Recognition Barrier Gate Debugging

1, How to debug the barrier gate license plate recognition management system? The vehicle barrier gate recognition system can automatically recognize license plates. When it recognizes a license plate in the warehouse, it will automatically turn on, making it convenient for users to pass. After installing the barrier gate license plate recognition management system, it needs to be debugged in a timely manner. The specific debugging method is: 1. System debugging. (1) Sensitivity adjustment of the ground sensing of the barrier gate control box. (2) Place the barrier gate in manual mode and check if the control box opens, closes, and stops normally; Activate the barrier gate and observe whether the fully open and fully closed positions are effective; Is the motor functioning properly; Is the operating range of the linkage mechanism normal; Test run more than four times. (3) Set the barrier gate to automatic mode and perform automatic pole dropping and anti smashing vehicle debugging. The method is to simulate vehicle entering, passing, and pole dropping; During the process of lowering the pole, the car comes to a stop when entering the pole. 2. Adjusting the angle of the license plate recognition area and adjusting the camera's universal joint can adjust the parallelism of the displayed image in license plate recognition. Pay attention to the relationship between the installation height and the corresponding effective recognition distance. 3. Barrier gate debugging (1) limit detection of gate rod: Use a triple switch or the start, fall, and stop operation on the barrier gate control board to carefully observe whether the barrier gate rod is in a vertical and parallel state, and check whether the limit is stuck. (2) Opening operation: Press the start button to observe whether the barrier gate has been raised to a vertical position and whether there is any shaking during the lifting process. If there is, adjust the assist spring. (3) Closing operation: Press the drop button to observe whether the barrier gate keeps landing parallel to the island, and whether there is any shaking of the pole during the drop process. If there is, adjust the assist spring. (4) Stop operation: During the process of lifting or lowering the barrier gate, press the stop button to immediately stop the barrier gate. (5) Anti smashing vehicle detection: Open the barrier gate pole to the vertical position, press the drop pole or short-circuit external grounding sense to add common. During the normal process of dropping the gate, short-circuit the external grounding sense and common again, and observe whether the barrier gate pole stops or restarts. 4. Ground sensing performance debugging (1) Brake drop detection: Use a large iron block to press down on the vehicle detection coil. At this time, the detection light on the ground sensing detector is always on, and there is no switch signal output from the ground sensing; When the iron block leaves again, the detector detects that the light has returned to normal and there is a relay signal output, causing the barrier gate to fall. (2) Anti smashing vehicle detection: During the process of falling the gate, if the iron block is re placed, the gate will stop or restart the lifting rod, and the anti smashing detection of the gate will be normal; Abnormal wiring needs to be checked. Can be tested multiple times to ensure accuracy. 2, How to input license plate numbers into the barrier gate license plate recognition management system? Many barrier gates have license plate recognition management systems, especially in residential areas. Homeowners in residential areas can go to the property management to input license plate information. This way, the gate at the entrance will automatically open when they go home or out every day, and it can also prevent vehicles from outside the community from entering and leaving the community casually, making it convenient to maintain order in the community. So, how to input license plate numbers into barrier gates? Barrier gates equipped with license plate recognition management systems are usually used in conjunction with computers. If you want to enter the license plate number, you can go to the property management office and submit your own license plate number. The property management will enter the license plate in the computer's input interface and enter the license plate number in the license plate information column, which is very convenient.
