Through the solution, there are three common reasons for the abnormal output of the image of the license plate recognition system:

One is the camera unit of the license plate recognition system

Not working properly, resulting in the camera unit not capturing relevant data, which in turn causes the camera to have no relevant output image data.

Second, there are problems with the connection hardware of the camera unit, such as incorrect connection or breakage of the lens drive cable, incorrect or broken connection of the camera and the control board, and poor connection of the analog video input interface of the access recognizer. Data cannot be output normally.

The third is that there is an error in the access command of the camera unit of the license plate recognition system, and the output command cannot be communicated normally. After finding the reason why the image of the license plate recognition system cannot be output normally, friends who have a certain installation foundation will know how to solve the problem that the image of the license plate recognition system cannot be normal. The output problem.

The first step is to check whether the camera unit has data to output. If not, it means that the camera unit has not captured relevant data. At this time, you can check whether the camera unit is installed correctly and whether it can shoot normally, otherwise directly replace the camera unit. 

The second step is to check that there is an error in the access command of the camera unit software of the license plate recognition system , and the output command cannot be communicated normally. The quality of the error must be debugged to enable it to issue the transmission quality normally.

The third step is to check the line, focusing on checking whether the lens drive line, the camera and the control board are connected incorrectly or broken, to ensure that the line is correctly connected, and there is no break; at the same time, pay attention to check the contact problems between various hardware The poor contact should be solved to ensure that the circuit will not have various failure problems. The license plate recognition system is an important intelligent facility for intelligent parking, improving residential vehicles, parking lots, hotels, schools, shopping malls and other property vehicle entrances and exits. Its application will ensure the efficiency of vehicles entering and exiting these property sites, and will enhance the automation and intelligence of property entry and exit vehicles. Management has positive significance. Its application will also effectively solve the traffic congestion that often occurs in these property sites, so we must ensure that the license plate recognition system can be used normally without various failures. In this way, the application significance of the license plate recognition system can be played to promote The city will build smart transportation, smart parking lots, and smart communities.
