Smart Parking System Frequently Asked Questions Dealing Have you ever encountered?
With the gradual spread of parking problems, many residential communities have basically installed an intelligent parking system. Although the parking system is bought from the parking companies, they are responsible for the failure, but the property still needs proper maintenance. The relationship between the two is complementary, so as to better extend the life of the parking system.
The intelligent parking system is generally composed of entrance control machines, exit control machines, intelligent barriers, geomagnetic coils, residual display screens, image recognition equipment, system software, and management workstations. Routine maintenance generally starts from these aspects. .
1 Entrance control machine: The car is pressed into the sensing area. The call button and the ticket key light are off, and there is no voice prompt.
1. Check whether the SCM is working.
2. Does the sensor sense?
3, check whether there is a problem with light.
4, ticket lamp wiring is a problem.
2 license plate recognition: the recorded license plate can not be identified
A, the image is not clear
The difficulty in localization of the license plate area mainly comes from the collected images. Due to the diversity of the license plate images collected, and when the images are collected, it is affected by many factors, such as rain, fog, and light, which makes some license plate image quality appear different degrees. The difference.
In this case, the recognition result can only achieve satisfactory results only when the image is in focus. There are certain requirements for the photosensitive components of the parking lot system. The video camera must also be improved in some configurations. Look at the video settings are not normal (set properly), monitor resolution, color desktop size adjustment.
B. Damaged or stained license plate
In the actual application process in highways and cities, it is difficult to ensure that the license plates involved are not defaced. After a license plate is used for several years, pollution and wear will inevitably occur.
For this kind of situation, many smart parking systems have gradually solved this problem, but if it is too serious, it has to rely on artificial labor.
3 gates will not open: license plate recognition passed, gates will not open
1. Check whether the open terminal is connected firmly;
2. Check if there is a switch signal output for the opening and closing terminal. If not, then the relay control relay will be damaged and replace the controller control board;
3. If it is still not possible to open the gate, check if the barrier is dead.
4 LED display does not appear
1, check the LED power is normal; 2, check the LED chip is normal.
5 No voice prompt sound
1, check the voice chip; 2, check the potentiometer.
6 gates move up and down or often turn
1. Check the limit switch; 2. Check the CPU; 3. Check the limit switch; 4. Check the power switch.
Intake Manifold Air Pressure Sensor/MAP Sensor
The intake manifold Pressure Sensor is referred to as MAP, which is the main component of the D-type fuel injection system of the gasoline engine. As the basis for controlling the fuel injection quantity and ignition advance angle.The working principle of the intake manifold pressure sensor is to know the density of the air by measuring the absolute pressure in the intake pipe, and to calculate the amount of incoming air according to the speed of the engine.
