Parking system construction steps and details
The construction of parking lot system can be divided into the following steps according to the sequence:
Determine the position of barriers and card readers
1. When determining the position of barrier gates and card readers, the width of the lane should be ensured first, so that the vehicle can enter and exit smoothly. The width of the lane is generally not less than 3 meters and is about 4.5 meters.
2. The distance from the reader to the gate is generally 3.5 meters, and it is not less than 2.5 meters in the most recent time. It is mainly to prevent the front from touching the rail when reading the card.
3. For underground parking, reading equipment should be placed on a relatively level ground, otherwise it would be more troublesome for the vehicle to stop parking when going uphill or downhill.
4. For the underground parking lot, if there is a barrier above the barrier, you need to use a folding barrier. The height of the barrier is -1.2 meters, which is the position of the folding point.
5. The position of the gate gate and card reader equipment is directly related to the user's convenience. Once the position is determined to be in place, it will cause great trouble for the construction. Therefore, the project is in this respect. Experience is not a lot of engineering personnel, the first gate and card reader equipment installed in place, and then simulate the user, together with the staff to see if the positioning is appropriate, and then lay the pipeline.
Determine the location of the automatic ejector
In the parking lot where there is a temporary vehicle access, if a long-distance card reading device is selected and an automatic card ejector is selected at the same time, the automatic card ejection device is an independent body and is installed approximately 0.3 meters away from the card reading device in front of the card reading device. . If an ordinary card reading device is selected and an automatic card ejector is selected at the same time, the automatic card ejector and the card reader are installed in the same device, and the on-site construction does not need to consider this step.
Determine the camera installation location
The angle of view of the entrance and exit cameras is mainly for the location of the license plate when the vehicle enters and exits the card. Generally, the automatic iris lens is selected, and the installation height is generally 0.5-2 meters. If you do not select the image comparison function, you do not need to consider this item.
Determine the location of the booth
For parking lots with temporary vehicles, post boxes are generally placed at the exits, so that due to the need to place control consoles and other equipment within the toll booths, and at the same time, it is a work place for on-duty personnel. Therefore, there is a certain requirement for the size of the post office, and it is best not to Less than 4 square meters.
Determine the location of the control host
The control host is the core control unit of the entire parking lot system. If a parking lot is located near the entrance to the parking lot, it will be placed in the post office; if there is no post office, it will be placed in the central control room. However, the distance between the control host and the card reader is generally not more than 200 meters.
Parking system design parameters
1. Card reader (center distance) and barrier (center distance)> 2.5M;
2. The distance from the management computer (usually placed in the parking lot management booth) to the reader is <100M;
3 camera installation height: 2 - 2.5M;
4 sense coil size: 2M (long) X0.8M (width);
5. Minimum charge management booth area: 4 square meters (2M*2M);
6. In and out lane width: >3M;
7. Equipment installation base size: 0.4M (long) * 0.4M (wide);
Pipeline laying
The laying of pipelines is relatively simple. Before laying the pipelines, the signal properties, signal flow and power supply of each equipment are clarified against the schematics of the parking lot system and the pipeline diagram. The signal line and the power line should be worn separately. For the power line, lines with different voltage levels and different current levels cannot wear the same tube.
Wire model
1. Communication line (management computer to the entrance and exit machine): RVVP6*0.3mm;
2. Control line (inlet and exit gates): RVVP6*0.3mm;
3. Video cable (access camera to management computer): 75-5 coaxial cable;
4. The sense of the line: high temperature corrosion resistance single stranded multi-core 1.5mm2 wire wound 6 circles, buried depth 3cm - 5cm;
5. Power cord: (power supply to card reader, barrier, camera) RVV3*2.5mm;
Control machine and barrier installation
Cast a 10-20cm high-precision waterproof and crashworthy island (mounting base), and pre-lay pipelines in the middle of the entrance and exit gates. Use four expansion bolts to secure the entrance and exit gates to the islands.
Placement of geomagnetic coils
The embedding of the geomagnetic coils is performed at the same time as the paving of the exit and entrance lanes or paving of the road surface. When the road surface is paved or is being paved, a slot is placed on the lane adjacent to the entrance and exit of the entrance and exit gates (coils). Put in the cut slot, the slot width is 1.5CM), the size of the ground coil is 200CM (length) X80CM (width) X5CM (deep). The ground sense line is wound 5-6 times along the slot, and the two terminals of the coil are introduced into the cabinet of the entrance machine and the gate, and the slot is filled with cement or asphalt.
