Parking system wiring installation notes:
1, power supply:
Ensure sufficient power, try to use a linear power supply. Install the power supply as close as possible to the electrical equipment to avoid interference and transmission loss.
2, wiring:
Divided into power lines, communication lines, signal lines, pay attention to strong, weak separation of wiring, two pipes separated by more than 20cm.
Power cord: The wire is thick enough to use multiple wires.
Signal and communication lines: Shielded Category 5 twisted pair cable. The 485 bus must use a twisted pair of wires to connect A+, A-. It is recommended to use 4*0.5 four-core shielded cable when purchasing the wire.
Note the following points:
The shielded wire must not be used as a 0V voltage (power ground) connection.
Each shield circuit can only have one ground terminal.
When the shielded loop cannot be grounded, the shielded wire can be connected to another shielded loop in the network.
The signal grounds of the individual modules must be connected together.
If there is a breakpoint in the middle of the line, the breakpoint must be soldered and insulated.
Do not put the network cable with AC power.
The parking lot system is a network system that is set up through computers, network equipment, and lane management equipment to manage the entrance and exit of parking vehicles, the guidance of on-site traffic, and the collection of parking fees. It is a necessary tool for professional parking yard management companies. It collects and records the vehicle's in-and-out records and field locations to achieve dynamic and static integrated management of vehicle access and on-site vehicles. The system generally uses a radio frequency induction card as a carrier, records vehicle in and out information through a proximity card, and implements charging policies, management of charging accounts, and control of lane equipment through management software. The market of intelligent parking system is gradually expanding, and it is firmly in the market. What are the functions of the parking system?
1. Anti-dumping function: Parking system When the vehicle is directly below the barrier, the vehicle is detected by the ground coil, the barrier will not fall, and the parking system will not support the offline operation until all the vehicles have left directly below it. .
2. Pressure waves prevent people or car functions. In places where pedestrians may pass under the brake rods, in order to prevent deafness, pressure wave detectors must be installed so as to prevent the deterring of people while also preventing the deterrence.
3. Supports permanent and temporary card working methods, automatic identification, record storage.
4. Barrier can be manually opened after system power failure.
5. One car, one card, one in and one out, only when you enter, you can go out, and only after you go out, customers should be careful not to be deceived by the limited access control system. Such a system can make more than one card. .
6. Parking lot system full-position detection function: Set the parking lot parking space in the management computer. If the vehicle entering the parking lot arrives at the parking space, the computer will remind the administrator and display the parking space on the electronic display screen.
The length of service life of the parking management system depends not only on the quality of the parking management system itself, but also on the maintenance of the parking management system. If the quality of the car park management system is high, it must be strictly controlled during the procurement process. Do not lose profits because of small profits. In terms of maintenance, the management personnel's intentions are needed. For the open-air parking lot, the parking system used must have a waterproof effect so as to avoid damage due to moisture on the motherboard. For the parking system, the damage of the barrier is more common, and the main reason is that some managers will adjust the opening time of the barrier beyond the tolerance of the barrier to accelerate the traffic speed of the vehicle. The service life of the movement is shortened, which in turn shortens the service life of the parking system. In fact, the most effective maintenance method is to carry out regular maintenance work on the parking lot management system. For example, it is necessary to inspect whether or not the parts of the line connectors are loose or rotating.
