Vehicle Loop Detectors for Automatic Gates and Doors

图片
Loop detectors are installed to operate an automatic gate. Usually installed within the premises to open and close gates automatically by detecting the presents of a vehicle. The loop consists of several loops of wire which is installed on the driveway. When vehicles pass over the loop a relay is triggered. The sensitivity can be easily adjusted to suit all vehicles. Loop detectors can be installed to automatically open the gate for all vehicles going out of an area.

How Loop Detectors Work

How Loop Detectors Work A frequently asked question in the newsgroups is about how the vehicle detectors used in traffic lights and in car parks work. The author designed such a detector too many years ago for comfort, and has frequently posted replies to these questions. Here is one of those replies. It is not a definitive treatment of the subject, but should give you an overview of how loop detectors work. When you approach a traffic signal or car park boom gate, you may notice a rectangular "scar" where the road surface has been cut with a saw and then re-sealed. This is the sensor loop. The loop consists of several turns or wire buried in the roadway, and connected to an electronic circuit which can detect a car passing over it. Normally the loop is about 1m x 1.5m in size. How do the electronics detect the passage of the vehicle over the loop? There are three methods I know of: "Damped Oscillator" The loop is part of an oscillator circuit. The oscillato...
