Wiring Installation and Maintenance of Parking Lot System - Tigerwong

[tigerwong technology] wiring installation and maintenance of parking lot system; The composition of the parking lot system is the management center. The management control center is composed of high-performance industrial computer, printer and parking lot system management software. The management control center is responsible for processing the information collected by import and export equipment, processing the information, controlling peripheral equipment, and processing the information into qualified reports for use by the management department. The main interface converters used in this part are generally 485 conversion card, TCP / IP hub, optical fiber converter, parking card authorizer and other equipment. Entrance equipment. The imported equipment is composed of image capture system, intelligent lighting, gate, entrance and exit control machine of parking lot, vehicle detector, automatic card issuing system, remote card reading equipment, etc., which is mainly responsible for automatic identification, identity verification and automatic landing of internal vehicles entering the parking lot; Issue cards to foreign vehicles, capture and record the entry time and vehicle information, and automatically take off and land the gate.

Sometimes, parking lot management system, parking space display system and parking lot guidance system need to be installed in this part! Export equipment. The exit equipment is composed of image capture system, intelligent light supplement, road gate, parking lot entrance and exit controller, vehicle detector, remote card reading equipment, temporary meter, etc. it is mainly responsible for automatic identification, identity verification and automatic landing of internal vehicles driving out of the parking lot; Charge for external vehicles, and automatically take off and land the gate after charging. When the fixed card user's vehicle enters the parking lot, the entrance controller actively detects the entry of the vehicle and detects whether the card is valid. If it is effective, the road gate is opened and the vehicle can drive into the parking lot. The camera captures the photo of the vehicle and stores it in the management computer.

When the vehicle leaves the parking lot, the exit control machine automatically detects the arrival of the vehicle and judges the validity of the card. If it is effective, the gate is opened and the exit camera is triggered to capture the vehicle, and the vehicle can leave the parking lot. When the temporary card user's vehicle enters the parking lot, he / she receives the temporary card from the entrance control machine. The entrance camera captures the photo of the vehicle and stores it in the computer. The controller records the entry time of the vehicle and transmits it to the computer when it is online.

When leaving the parking lot, the entrance control function detects that it is a temporary card and prompts the driver to pay the fee. The temporary car must return the temporary card to the security guard and pay a certain fee. It can leave only after being confirmed by the security guard. Precautions for wiring installation: the power supply shall ensure sufficient power and try to use linear power supply. The power supply shall be installed as close to the electrical equipment as possible to avoid interference and transmission loss.The wiring shall be divided into power line, communication line and signal line. During wiring, pay attention to the separation of strong and weak current. The distance between the two pipes shall be greater than 20cm. The wire diameter of the power line shall be thick enough and multi strand conductors shall be used. Shielded category 5 twisted pair shall be used for signal line and communication line.

The 485 bus must use a pair of twisted pair wires to connect a . a- When purchasing wire, it is recommended to use 4 * 0.5 four core shielded wire. At the same time, it should be noted that the shielded wire must not be used as the connecting wire of 0V voltage. Each shielded circuit can only have one grounding terminal. When the shielding circuit cannot be grounded, the shielding wire can be connected to another shielding circuit of the network. The signals of each module must be connected together. If there is a breakpoint in the middle of the line, the breakpoint shall be welded with soldering iron and insulated.

Do not put the network cable with the AC power supply. Parking lot system is a set of network system built through computer, network equipment and lane management equipment to manage the access of vehicles in the parking lot, the guidance of traffic flow in the parking lot and the collection of parking fees. It is a necessary tool for professional parking lot management companies. It realizes the dynamic and static comprehensive management of vehicle access and on-site vehicles by collecting and recording vehicle access records and on-site positions. The system generally takes the RF induction card as the carrier, records the vehicle access information through the induction card, and completes the functions of charging strategy, charging accounting management, Lane equipment control and so on through the management software.

Parking lot system function; The market of intelligent parking lot system is gradually expanding and is stable in the market. What functions should the parking lot system have? 1. Anti smashing function: when the vehicle is directly below the gate, the ground induction coil detects the presence of the vehicle, and the gate will not fall. The parking system supports offline operation until all vehicles leave directly below it. 2. Pressure wave anti smashing function. In places where pedestrians may pass under the brake rod, in order to prevent people from being hit, pressure wave detector must be installed to prevent people from being hit and vehicles from being hit at the same time. 3. Support the working mode of permanent card and temporary card, automatic identification, recording and storage. 4. The gateway can be opened manually after system power failure. 5. One car, one card, one in and one out. You can only go out when you enter, and you can only come in after you go out. Customers should be careful not to be deceived by the system modified with limited access control.

In such a system, one card can go in and out more. 6. Parking lot system full space detection function: set the parking space of the parking lot in the management computer. If the vehicles entering the parking lot arrive at the number of parking spaces, the computer will remind the administrator and display that the parking space is full on the electronic display screen. The service life of the parking lot management system depends not only on the quality of the parking lot management system itself, but also on the maintenance of the parking lot management system. If you want to improve the quality of the parking lot management system, you should strictly control the quality when purchasing, and don't get small profits and lose big profits. In terms of maintenance, managers need to pay attention.

For open-air parking lots, the parking lot system used must have waterproof effect to avoid damage caused by moisture on the main board. For the parking lot system, the damage of the gate is common. The main reason is that some managers will adjust the opening time of the gate beyond the bearing range of the gate in order to speed up the traffic speed of vehicles, so as to shorten the service life of the movement, and then shorten the service life of the parking lot system. In fact, the most effective maintenance method is to regularly maintain the parking lot management system, for example, check whether the line joints of each part are loose or whether the rotating parts need lubrication, etc.
