**Wing Gate** is an intelligent channel management system developed and manufactured by Baowei Intelligent Technology Co., Ltd. after years of research and development. This advanced equipment integrates various reading and writing devices, mechanical components, electronic systems, microprocessor control, and multiple reading technologies into a single, cohesive unit. It features reliable safety protection mechanisms, real-time alarm systems, and user-friendly direction indication interfaces, enabling efficient and intelligent control over the flow of vehicles or people.
To ensure that the Wing Gate operates smoothly under normal conditions, it's essential to pay attention to the induction coil it is connected to. Several key factors influence the performance of the coil, including the material used, its shape, and how it is installed underground. Proper installation is crucial for optimal functionality, so the following guidelines should be followed carefully:
1. The coil should ideally be rectangular in shape, unless site constraints prevent this. The longer sides of the coil should be positioned perpendicular to the direction of vehicle movement. It is recommended that the distance between the two long sides is around 1 meter. The length of each long side depends on the road width and should typically be 0.5 meters narrower than the road itself. The number of turns in the coil is usually 4 or 6, and if two coils are placed next to each other, one should have 4 turns and the other 6.
2. **Crosstalk** can occur when two induction coils are too close, causing their magnetic fields to interfere with each other. This can lead to incorrect detection results or even system lockups. To prevent crosstalk, consider the following measures:
A. Use different numbers of turns for adjacent coils of the same size to change their operating frequencies. For example, one coil can have 4 turns, while the other has 6.
B. Increase the spacing between adjacent coils. The distance between them should be at least 3 meters to minimize interference.
C. Ensure that the lead wires from the coil are properly shielded and grounded at the detector end. The cables and connectors should be made of stranded copper wire, and it's best to avoid any mid-cable connections. If connections are necessary, they should be soldered securely and placed in a waterproof location. The cross-sectional area of the conductor should not be less than 0.5 square millimeters.
3. **Installation method**: Before installing the coil, cut a groove into the road using a road cutter. Chamfer the four corners at a 45-degree angle to prevent sharp edges from damaging the cable. The groove should be approximately 4 mm wide and 30–50 mm deep. A separate slot must also be cut to route the lead wires to the roadside. When laying the cable, make sure there is enough length to connect to the loop sensor, and avoid having any joints in the middle. After winding the coil, pass the cable through the lead-out slot. The output leads should be tightly twisted, with at least 1 meter of 20-strand twisted wire. The maximum length of the lead should not exceed 10 meters. Since longer leads reduce sensitivity, it's important to keep the lead as short as possible for optimal performance.
