Intelligent parking lot system cable and signal wiring requirements

Parking system wiring, there are two requirements, a specification is safe and reliable, 2 it is to strive for wiring tidy and beautiful.In the process of the whole wiring should pay attention to the following:
1. If the building wiring installation, cable should keep balance or level, and combined with outside casing, ensure cable beautiful appearance;
2. In order to avoid interference, the 220 v wire to separated from signal lines laid, not covet convenient place in the same pipeline, spacing them best in more than 50 cm;
3. All walk line must be casing, can choose the PVC or galvanized pipe, protect cables, avoid cable bite by the rat;
4. Go have a breakpoint connecting line process, with a soldering iron welding and make insulation treatment;Wiring to tag, if after debugging maintenance is simple a lot.

here are specific cables, signal lines, wiring requirements.


a, cable entrance gate, need 220 v power supply, access control machine adopts three core shielded wire (RVVP3 * 1.5), and generally received a dedicated line UPS power supply, in some cases AC220V power also can access to the nearest, but should comply with the relevant specification, to ensure the ground real grounding AC220V socket in the system.

,
parking line networking mode can be divided into: 485 communication, TCP/IP communications, RS422 communication 485 Internet line is shielded twisted-pair cable must be used, such as RVVSP2 * 0.5, 485 bus length, are theoretically can reach 1200 meters, suggested that not more than 1000 meters.Please choose if more than 485 hub or repeater to improve the communication environment.In order to guarantee the stability of communication, in the end of the communication line resistance, or connect all the shielding layer, can be hung up or according to the situation at the end from the earth.485 network must be the total linear structure, do not allow the full or partial star structure.TCP/IP networking line can choose super five categories of shielded twisted-pair cable, control the machine to the switch or HUB distance less than 100 meters.
