Nowadays, many parking lot are equipped with intelligent parking system, intelligent parking system is generally composed of entrance control machine, exit control machine, automatic barrier gate, sensor coil, residual display screen, image recognition equipment, system software, management workstation and so on.
The following are common failures of the parking system for maintenance purposes only.
Parking lot license plate recognition equipment can not clearly identify the number
The difficulty of vehicle license plate area identification mainly comes from the collected images.
Due to the diversity of license plate images collected and the influence of rain, fog, light and other factors, the quality of some license plate images is different.
In this case, if the image can be clearly focused, the recognition results can be satisfied.
This has certain requirements for the photosensitive parts of the parking system. The camera also needs some configuration improvements. Display resolution, color desktop size adjustment.
The intelligent parking system identified the vehicle, but the gate was not raised
Check whether the switch terminal is firmly connected; Check whether there is switch signal output in the switch terminal. If there is no switch signal output, the track brake control relay is broken. Replace the control board of the control machine; If the brake still cannot be opened, check whether the lane brake is dead.
Vehicle passed, but the gates were not down
Possible reasons are: improper embedding of the ground sensing coil or damaged or broken coil; The power of the vehicle detector power supply is insufficient (Max250mA) or the induction sensitivity is adjusted improperly (too high or too low); The interface between the ground detector and the gate controller is disconnected or in poor contact.
LED display of parking system is not displayed
Check whether the LED power supply is normal; Check whether the LED chip is normal.
No voice prompt
Check the voice chip; Check the potentiometer.
