Intelligent parking system common problem solution

As parking problems gradually spread, many residential communities have basically installed intelligent parking systems. Although the parking system is bought from parking companies, they are responsible for the failure, but the property still needs proper maintenance. , complement each other, in order to better extend the life of the parking system.

　　
The intelligent parking lot system generally consists of an entrance control machine, an exit control machine, a smart gate, a ground sense coil, a residual display, an image recognition device, a system software, a management workstation, etc., and daily maintenance generally starts from these aspects. .
 
　 First, the entrance control machine: the car is pressed into the sensing area, the call button and the button light are not lit, and there is no voice prompt.
 
1. Check if the microcontroller is working.
 
2. Whether the sensor is inductive;
 
3. Check if there is any problem with the diaphragm;
 
4. Is there any problem with the ticket wiring?


 
　　 Second, the license plate recognition: the recorded license plate, can not be identified
 
1, the image is not clear
 
The difficulty of positioning the license plate area is mainly from the collected images. Due to the diversity of the collected license plate images, and the image is affected by many factors, such as rain, fog, light, etc., some license plate image quality appears different degrees. The difference.
 
In this case, the recognition result can only achieve a satisfactory result if the image is sharply focused. That has certain requirements for the photosensitive parts of the parking system. The video camera will also need to improve some configurations. Look at the video settings are not normal (set normal), display resolution, color desktop size adjustment.
 
2, the license plate is damaged or stained
 
In the actual application process on the road and in the city, it is difficult to ensure that the license plates involved are not defaced. After several years of use, the license plate will inevitably become polluted and worn.
 
In this case, many intelligent parking systems have gradually solved such problems, but if it is too serious, it has to rely on labor.

 
　 Third, the gate does not open: the license plate recognition passes, the gate does not open
 
1. Check if the open wiring terminal is securely connected;
 
2. Check whether the switch terminal has a switch signal output. If not, the gate control relay is broken and replace the control panel of the control unit;
 
3. If you still can't open the gate, check if the gate is dead.
 
　 Fourth, the display LED does not display
 
1. Check if the LED power supply is normal;

2. Check if the LED chip is normal.
 
　　 Five, no voice prompts
 
1. Check the voice chip;

2. Check the potentiometer.
 
　 6. The gates move up and down or often turn over the head.
 

1. Check the limit switch;

2, check the CPU;

3. Check the limit switch;

4. Check the power off switch.
