Daozha, which is one of the channel management equipments, is widely used in airports, subway stations, stations, docks, attractions, parks, and unit walkways. It is an ideal management and grooming device for pedestrians with high-frequency access. The influence of the induction coil on the operation state of the gate gate is very important. Barrier coil shape and number of turns, unless the conditions do not allow, the search coil should be rectangular. The two long sides are perpendicular to the direction of motion of the vehicle and are recommended to be 1 meter apart. The length of the long side depends on the width of the road and is usually 0.5 meters narrower than the width of the road. Barrier coils are mainly affected by three problems: the coil material, the shape of the coil, and whether the construction is properly installed.
When the barrier induction coils are very close together, the magnetic fields of the two coils are superposed, causing mutual interference. This phenomenon is coil crosstalk. Barrier crosstalk can cause erroneous detection results and loop detector deadlock. To avoid coil crosstalk, we should:
1. The same number of turns in the same size of the gate to change the operating frequency of the coil. It is generally recommended that one lap is 4 and the other is 6 laps.
2. Increase the distance between adjacent coils of the gate. It must be ensured that the spacing between the detection coils is greater than 3 meters.
3, good shielding of the lead wire from the barrier coil, shielded wire must be grounded at the detector end. Coil cables and connectors are preferably made of stranded copper wire. It is best not to have a connection between the cable and the connector.
The coil installation method of the gate gate is to be embedded in the road surface firstly with a slicing machine and chamfered at 45 degrees on four corners to prevent the sharp corner from damaging the coil cable. When laying the cable, leave enough length to connect to the loop sensor and ensure there is no joint in the middle. After winding the coil cable, lead the cable through the lead-out slot. 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.
Shenzhen Hongshunmeng Co., Ltd. specializes in R&D and production of three-roll gates, intelligent barrier gates, barrier gates, swing gates, and full-height gates. It is committed to customizing personalized intelligent channel solutions, intelligent security management systems, intelligent access control, attendance, consumption, and charges. The systems of governance and tickets provide a civilized and orderly way for communities, exhibitions, conference halls, canteens, hotels, museums, gymnasiums, clubs, subways, stations, terminals, schools, prisons, and stations.
All product shells are made of stainless steel. The internal components of the box are all made of stainless steel or rust-proof and anti-corrosion treatment. They are durable and rust-proof, and have strong anti-destructive power. Smooth operation, no jitter; low noise, low power consumption, energy saving and environmental protection. Welcome to inquire!
