Good Quality Loop Coil With Resistance High Temperature.
Good Quality Loop Coil
Good quality loo coil consists of a surrounding coil and an inductive digital circuit board. Anti-corrosion good quality loop coil (wire material adopts special anti-corrosion line for grounding, has the characteristics of wear resistance and corrosion resistance), the good quality loop coil is buried in the underground 10-15CM, as long as there is a vehicle passing on the road, the coil generates an induced current and transmits it to the circuit board, and then the circuit The board generates a TTL level signal or a dry junction signal to the controller or the electric gate. The vehicle detector in front of the entrance ticket box is mainly matched with the entrance control board and the automatic card issuing machine, and realizes the function of “having a car card” and “one car only one card”. When the vehicle enters the signal and presses the card take-up button, the card-issuing card-issuing machine automatically issues the card, and the vehicle detector under the gate railing is matched with the gate control board, which acts as a flood prevention function when the vehicle passes by.
The car automatic prevents losing cards. Everyone should know that in the standard one-in-one-out system, temporary vehicles come into play through automatic card retrieval. He only needs to press the button. The role of the sense of the ground is to take the card when the vehicle is in the present, instead of the person pressing the button to get the card. Stops after the car have passed. The ground-sensing card is used to identify the direction of the vehicle in a long-distance card reading system. There are also two directions for the entrance and exit gates. First, let the cargo. When the car is in the sense of the ground, the brake lever will not fall. The car passed the pole. loop detector coil, traffic detection coil, loop sensor coil.
According to the drawings, draw the lines of the coil size on the road surface, and cut the square coil groove by the road cutting machine according to the line.
1. The size of the sense coil in the parking lot is generally 1.8 meters wide and 1.2 meters long.
2. Cut the chamfer of 10 cm X 10 cm at the corner to prevent the hard concrete from cutting the coil at right angles.
3. The depth of the groove is 4 cm, the width of the coil groove is 0.5 cm, the width of the coil lead groove is 1 cm, and the depth and width should be uniform. It should be avoided as much as possible.
4. There should be no debris in the cut tank, especially if there is no hard object. Rinse it with water first, then dry it.
5. The lead groove of the good quality loop coil should be cut into the safe island to avoid the lead exposed on the road surface. Buried ground coil After the coil groove is cut and cleaned and dried, the coil should be buried in time to prevent debris from falling into the groove.
