Detailed Explanation On Debugging Of License Plate Recognition Barrier

1、 How to debug the road gate license plate recognition management system Vehicle road gate recognition system can automatically recognize the license plate. When the license plate in the warehouse is identified, it will automatically open for the convenience of users. After the road gate license plate recognition management system is installed, it needs to be debugged in time. The specific debugging methods are: 1. System debugging (1) Sensitivity adjustment of the road gate control box. (2) Put the barrier gate in the manual state, and check whether the control box is opened, closed and stopped normally; Start the barrier gate and observe whether the fully open and fully closed positions work; Whether the motor is normal; Whether the operation range of linkage mechanism is normal; Test run for more than four times. (3) Put the barrier gate in automatic state, and conduct automatic rod dropping commissioning and anti smashing commissioning. The method is: simulate the vehicle entering, passing and rod dropping; In the process of rod lowering, the vehicle enters the rod and stops. 2. Angle adjustment of license plate recognition area The universal joint of the camera can adjust the parallelism of the image displayed in license plate recognition. Note the relationship between the installation height and the corresponding effective recognition distance. 3. Track gate commissioning (1) Limit detection of gate lever. (2) Opening operation: press the start key to observe whether the barrier has been raised to the vertical state, whether the lever shakes during the rod lifting process, and if so, adjust the boost spring. (3) Closing operation: press the down key to observe whether the barrier gate has always landed in parallel with the island, and whether the rod shakes during the rod dropping process. If so, adjust the boost spring. (4) Stop operation: press the stop button during the lifting or lowering of the barrier gate to check whether the barrier gate will stop immediately. (5) Anti smashing detection: open the barrier bar to the vertical position, press the bar to drop or short-circuit the external grounding sense to make it public. In the process of normal brake dropping, short-circuit the external grounding sense to make it public again, and observe whether the barrier bar stops or lifts again. 4. Ground sensor performance commissioning (1) Closing detection: press the vehicle detection coil with a large iron block, at this time, the detection lamp on the ground sensor detector is always on, and there is no switch signal output of the ground sensor; When the iron block leaves again, the detector's detection light returns to normal and there is relay signal transmission, and the barrier gate is in the state of closing. (2) Anti smashing detection: in the process of falling the gate, put on the iron block again, stop the gate or restart the lifting rod, and the anti smashing detection of the gate is normal; Check the wiring if it is abnormal. The test can be repeated several times to ensure accuracy. 2、 How to enter the license plate number in the road gate license plate recognition management system Many road gates have a license plate recognition management system, especially in the community. The owners in the community can go to the property to enter the license plate information, so that the gate at the door will automatically open when they go home or go out every day. It can also prevent vehicles outside the community from randomly entering and leaving the community, which is convenient to maintain the order of the community. How can the road gate enter the license plate number? The road gate equipped with the license plate recognition management system will usually be used with the computer. If you want to enter the license plate number, you can go to the property office and submit your own license plate number. The property office will enter the license plate in the computer entry interface. It is convenient to enter the license plate number in the license plate information column
