With the increasing parking problem, many residential communities have basically installed intelligent parking system. The intelligent parking system generally consists of entrance control machine, exit control machine, intelligent gate, ground sense coil, residual display, and image. Identification equipment, system software, management workstations, etc. The following are the common faults and solutions for the parking system.
1. 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.
A. Check if the microcontroller is working.
B. Whether the sensor is inductive;
C. Check if there is a problem with the diaphragm;
D. Is there any problem with the ticket wiring?

2, license plate recognition: recorded license plate, can not identify
A, 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 (normal settings), display resolution, color desktop size adjustment.
B, 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, and the license plate will inevitably become polluted and worn after several years of use.
In this case, many intelligent parking systems have gradually solved such problems, but if it is too serious, it has to be artificial.
3, the gate does not open: the license plate recognition passed, the gate does not open
A. Check if the open terminal is securely connected;
B. Check whether the switch terminal has a switch signal output. If not, the gate control relay is broken, and the control panel is replaced.
C. If you still can't open the gate, check if the gate is dead.
4, the display's LED does not display
A. Check if the LED power supply is normal; B. Check if the LED chip is normal.
5, no voice prompts
A. Check the voice chip; B. Check the potentiometer.
6, the gate up and down movement or often turn over the head
A, check the limit switch; B, check the CPU; C, check the limit switch; D, check the power off switch.
7, the car does not go down
possible reason:
1 The ground sense coil is buried incorrectly or the coil is damaged or broken;
2 vehicle detector power shortage (Max250mA) or improper sensing sensitivity (too high or too low);
The "COM" end of the 3 sense detector is disconnected or in poor contact with the "GND" common ground of the gate controller.
8. Click the [Open Gate] button in the software monitoring interface, the gate is not open, but the manual button can be used to open the gate.
possible reason:
1 The “control switch†in the card reader is not short-circuited (it is disconnected at the factory and is in offline working state. When it is connected with the computer, it must be short-circuited online);
2 The computer and the card reader cannot communicate normally, and the controller does not receive the open command. (Check if the connection of the computer serial port is normal and the parameter setting is correct)
9, the computer is unstable, the system often goes wrong, it is easy to crash when operating the software.
A. Reinstall the operating system.
B. Is the CPU fan bad and the temperature inside the chassis is normal?
C. Check if there are too many vehicle records in the computer.
10, the computer network is unstable, when the time is disconnected
A.RJ-4S head is damaged
Is the power of B.HUB stable?
C. Whether the network card settings are changed
Excavator Quick Couple
An excavator quick coupler is a mechanism that enables the operator to quickly and easily change out attachments on an excavator without having to manually detach and reattach them. It is essentially a hydraulic clamp that connects the excavator arm to the attachment, allowing for quick and efficient tool changes. This saves time and enhances productivity on job sites where multiple attachments are needed.qa
