Vehicle Loop detector principle

Vehicle detector principle
:vehicle detector is the use of LC oscillator to detect whether there are metal objects at the coil to achieve the detection of the vehicle. Vehicle detector has a fixed capacitance, and then in the ground around a 3-5 m long coil, when the coil is not the vehicle when the inductance is relatively low, LC oscillation frequency is relatively high, the frequency is greater than 50Hz, when the coil has Vehicle, the inductance increased sharply, the frequency of lower-end LC oscillation, this time the frequency is less than 50Hz. Vehicle detector can be based on the frequency of LC oscillation to determine whether there is a vehicle through.
In this case,
Vehicle detectors are commonly used in parking lot systems. A, Vehicle detectors are used in conjunction with the barrier, and the B vehicle detector is used in conjunction with an automatic card reader.
In this case,
When the vehicle detector and the barrier with the use of vehicles at this time detector can play, anti-smashed cars and cars off the role of automatic gate.
In this case,
When: Vehicle detector and automatic card reader with the use of vehicles at this time detector can play a car to take the card, but also to achieve a car can only take a role in the card.

 Inductive Loop Detector works by detecting an inductance change in wire loop (coil) that is buried in road. It does that by measuring the frequency of the internal oscillator which powers the mentioned coil. When a metallic object moves over the coil it changes its inductance and that in turn changes the oscillator frequency which is measured by the microcontroller. It is used for vehicle access control at door and barrier controls, for monitoring the occupancy and for vehicle counting in parking garages, for traffic light installations and traffic controllers, for direction and speed detection of vehicle traffic (if dual channel version is used), in car-wash plants, etc.

How Barrier Gate Working With Jutai Products?

Barrier Gate Working With Jutai Products Gate barriers are typically found at level crossings, parking facilities, checkpoints and entrances to restricted areas. They are also the usual method for controlling passage through toll booths, and can also be found on some freeway. entrance ramps which are automatically controlled to drop to restrict traffic in the event of accident cleanup or road closures without the need to dispatch road workers or law enforcement to use a vehicle to block the way. Some barrier gates are automatic and powered, others are manually operated. In some places, boom gates are installed across suburban streets as a traffic calming measure, preventing through traffic, while allowing to take advantage of the shorter and more direct route authorized vehicles such as emergency services and buses. barrier gate installed in Taiwan Automatic boom barrier gate can be operated through Jutai Products 1. Loop Detector 2. RFID tags / RFID reader / Proximity

Why Choose JUTAI Automatic Gate System?

Why Choose JUTAI Automatic Gate System?  The boom barrier is the most common type of vehicle blocking device. It is an entrance and exit management device especially used to manage the driving passage of motor vehicles. It is widely used in highway toll stations and parking lot management systems to achieve the purpose of managing vehicle access. The security gate is usually composed of a reduction gearbox, a motor, (or a hydraulic) transmission mechanism, a balancing device, a chassis, a barrier arm., etc. The electric gate can be independently realized by wireless remote control or can be managed through a parking lot RFID system. The system is automatically managed and is often used in conjunction with the sense of the ground loop detectors (vehicle detectors). With the increasing number of vehicles, the demand for vehicle access management is also increasing, and people have put forward higher requirements for the performance of the boom gates . Such as the integrated brake
