Vehicle Loop Detector Coil

Vehicle Loop Detector coil working principle. Before introducing the principle of the ground-sensing coil detector, we will introduce what is a ground-sensing coil. The “traffic detection coil” is an oscillating circuit. It is constructed in such a way that a circular groove is formed on the ground, about 1 meter in diameter, or a rectangular groove of comparable area, and two to three turns of wire are buried in the groove, which constitutes A loop detection coil buried in the earth's surface, this coil is part of an oscillating circuit. It consists of an oscillating circuit and a capacitor. The principle is that the oscillation is stable and reliable. This oscillating signal is sent to the frequency measuring circuit composed of the single-chip microcomputer through the conversion. Measure the frequency of this oscillator. When there is a large metal object such as a car passing through, the change of the oscillation frequency is caused by the change of the space medium (the oscillation frequency increases when there is a metal object), and this change is used as the confirmation signal of the car through the "loop detector coil", and The time interval between the start and end of the signal can, in turn, be used to measure the speed of the car. This is the "vehicle loop detector coil." The key to the technology is that the designed oscillator is stable and reliable, and the frequency changes significantly when the car passes.

The electronic weight bridge is an oscillating circuit that detects if there is a speed through which the car passes. The principle of action is: first create a circular groove on the ground, about 1 meter in diameter, or a rectangular groove of equal area, embedding two or three turns of wire in the groove, which constitutes a buried Inductive coil on the surface. This coil is part of the oscillating circuit, which consists of an oscillating circuit. The frequency of the oscillator can be measured by converting the oscillating signal to a frequency measuring circuit composed of a single chip microcomputer.

When there is a large metal object such as a car passing through, the change of the oscillation frequency is caused by the change of the space medium (the oscillation frequency increases when there is a metal object), and the single-chip microcomputer can measure the frequency value of the change, that is, it can be perceived that the car passes by. . At the same time, the time interval between the beginning and the end of this signal can be used to measure the moving speed of the car.  when we choose the vehicle loop detector coil. we will take the quality into consider.  If we can be guaranteed the quality of the vehicle detector coil. then our customer will reduce some maintenance cost.  Therefore.  When you need order vehicle loop detector coil. please feel free to contact us. we will give you reply as soon as possible.
