And all the cabling must be sleeved, PVC tubing and galvanized tubing can be used to prevent rats from biting off the circuit and causing problems;

If there is a breakpoint in the middle of the circuit, the breakpoint must be soldered with a soldering iron and insulated. The cable must be marked during the wiring to facilitate installation, commissioning and maintenance.

Bingzhong CAK1000 parking master control board, designed for parking environment, built-in accessories using the United States imported Lattice chip technology, Lattice is today's cutting-edge electronic application technology, its high operating frequency, anti-interference ability, large-scale integration, performance It is stable and has strong computing ability. It has applied advanced interface protection technology and circuit protection technology and is widely used in large-scale control systems and industrial control fields.

The board adopts SMD chip technology, high-precision components, and mature and reasonable circuit design to reduce the number of discrete devices and use large-scale integrated circuits to ensure the safety and stability of the entire system.

1. The power line entrance gate, entrance and exit control machine needs 220V power supply, adopts three-core shielded cable (RVVP3*1.5), generally receives special line UPS special line power supply, in some cases AC220V power supply can also be accessed nearby, but should be in line with For related specifications, ensure that the ground wire in the AC220V socket in the system is grounded.

2. Network cable (control machine - controller or controller - computer)

Parking network can be divided into: 485 communication, TCP / IP communication, RS422 communication, etc. 485 network cable must use shielded twisted pair RVVSP2 * 0.5, 485 bus length, in theory, can reach 1200 meters, it is recommended not to exceed 1000 meters.

If more than please use 485HUB or repeater to improve the communication environment. In order to ensure the stability of communication, connect the resistance at the end of the communication line, or connect all the shielding layers together, and the end can be suspended or connected to the ground according to the situation. The 485 network must be a bus type structure that does not allow full or partial star configuration. The TCP/IP network cable can be selected from Category 5 unshielded twisted pair cables. The distance from the controller to the switch or HUB is less than 100 meters.

1. Long distance reader signal lines (reader-controller): The reader signal line uses a four-core shielded cable (RVVP4*0.5).

4. Display signal line (display screen-controller): The signal line adopts two-core shielded wire: RVVP2*0.5. In order to make the signal wire undisturbed, it should be laid separately from the power wire when laying.

5, control line (barrier - control machine): standard car park control line uses four-core shielded line (RVVP4 * 0.5), simple parking (MAC board) uses two-core shielded line (RVVP2 * 0.5), according to the specific circumstances of parking Field type will be determined.

6. Video cable (camera-control room computer): The video cable uses the SYV75-5 video cable. Do not connect it with other strong power systems. It should keep a distance of 500mm.

Third, the construction of the construction of the pipe (fabric) technical requirements Line pipe (trunk) wiring open and dark lines are two, open-line pipe requirements horizontal and vertical, neat and beautiful. Dark pipe requires short, smooth, and elbows. Fixation of line pipe (slot), line pipe (slot) should be fixed at every corner or linear distance more than 1.5 meters.

In the vertical nozzle that does not enter the box (box), after the wire is pierced, the nozzle should be sealed. In the access control wiring, the utilization of the diameter of the straight pipe should be 50% to 60%, and the utilization of the diameter of the bent pipe should be 40% to 50%. If special conditions need to be adjusted during the construction process, they must be approved by the company's leaders and customers before they can be constructed.

Sometimes it is necessary to determine the slot during the construction of the conduit (slot): The slot should be based on the following principles:

1 The principle of the shortest route;

2 does not destroy the original principle of strong electricity;

3 does not destroy the waterproof principle.

4 determine the slot width: According to the number of signal lines to determine the number of PVC pipe, and then determine the width of the slot.

5 Determine the groove depth: If a 16mm PVC tube is selected, the groove depth is 20-25mm; if a 20mm PVC tube is selected, the groove depth is 25-30mm.

6 trough appearance requirements: horizontal and vertical, uniform size.

7 Measurement of the slot: The cassette and the distribution box are calculated independently. All slots are measured from the beginning of the slot to the end of the slot. If the width of the slot exceeds 80mm, the length of the doublecable is calculated.

8 Sealing groove: The wall surface and ground surface after sealing the groove shall not be higher than the plane, and shall be level with the original plane.

IV. Technical requirements for equipment installation 1. The distance between the entrance and exit control machines and the automatic barrier gate control distance from the corresponding barriers shall not be less than three meters (the exit and entrance shall be the same).

9. The two wires drawn from the coil should be twisted with a density of no less than 50 knots per meter. Untwisted output leads will cause interference. The output lead length should generally not exceed 5 meters. Since the sensitivity of the detection coil decreases as the length of the lead increases, the length of the lead cable must be as short as possible.

6. The technical requirements of the safety islands are to build a circular concrete pier in the middle of the road, commonly known as a safety island. The safety island mainly plays the role of placing equipment and preventing vehicles from hitting the equipment. If the equipment is installed on the roadside because of the width of the road, the equipment installation foundation should be made on the side of the road. Safety island construction precautions:

1. If the size of the foundation to be installed on the equipment should be more than 10cm larger than the actual size of the equipment, prevent the expansion screw from bursting the foundation when fixing the equipment.

2, the safety island should be higher than the ground about 10cm-15cm.

If the ground on which the equipment is installed is an asphalt foundation, the foundation may be laid directly on the ground, but where the laying is to be done, a reinforcing bar (Φ20 or more) should be punched every 25 cm in a star shape, and the steel bar should be deeper than 20 cm deep in the ground. No less than 5 cm exposed.

VII. System Inspection and Testing 1. Pre-installation inspection: Prior to installation of the equipment, it is necessary to check the installation contract for the type and quantity of equipment in advance and determine the correctness of the equipment from the warehouse. After the equipment is taken from the warehouse, it is necessary to test all the equipment one by one to check whether the equipment is normal and to avoid trouble during installation.
