Vehicle Loop Detector / Barrier Gate/ Parking Management System From Shenzhen Jutai Comm Co., Ltd

-
Vehicle loop detector Application:

Loop detectors are used wherever vehicles have to be detected. Like monitoring and safe guarding access ways to counting vehicles.
The output signal can be used for controlling door and gate drive mechanisms, operating barriers, controlling traffic light systems
in car parks or activating card dispensers in car parks.

The LD-100 is a single channel inductive loop detectors. The principle is based on a change in the inductance within the loop
which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor.
Ease of use thanks to automatic calibration when the operating voltage is applied.




Product key words
Loop Detectors, vehicle loop detectors, loop sensors, vehicle sensors,
 car parking sensors, car park detectors
Application & Advantages
Loop detector is used in vehicle access control areas
 to keep the barrier gate opening until the vehicle leaves the covering area.
Features

1) Reset Switch : The reset switch enables the detector to be manually reset 

during registering and testing and it is a process of system recovery;

2) Selectable Pulse Time : This feature sets the length of time that
 the pulse relay will be lasting for 1 Second or 0.5 Seconds ;

3) Pulse Relay Selection : The Pulse Relay may be configured
 to activate on detection of a vehicle or when the vehicle leaves the loop;

4) Sensitivity Reinforcement : This feature sets the un-detecting level to
 a maximum sensitivity to prevent failing to detect vehicles as big trucks;

5) Switch Sensibility Adjustable : 4 sensitivity setting are available
 on the switches to change sensitivity ;

6) Switch Frequency Adjustable : 4 frequency settings are available 
to prevent signal interference with neighboring loops ;

7) Filtering Option : This option is used to provide a delay
 between detection of the vehicle and switching of the output relay . 
This relay is normally used to prevent false detection 
of small or fast moving objects ;

8) Permanent Presence Option : This feature ensures the detection 
of the vehicle will be maintained when the vehicle stays within the loop 
area 
for extended periods

Vehicle Loop Detectors, Loops, and Loop Accessories for Gate Operators & Other Equipment Free Exit or Entrance for Automated Gates and Doors:  Loop detectors and loops may be used for a variety of applications. Vehicle loop detectors are frequently used to provide free entrance and/or free exit for traffic. Wire loop detector directly to  gate operator  or overhead door, connect to buried loop, and allow larger metal objects which drive over loop to trigger the gate or door to open, or close. Loops remain practically invisible, buried beneath gravel, asphalt, or concrete driveways. Vehicle loop detectors are a safe and reliable way of controlling an assortment of equipment. Safety Devices for Automated Gates and Doors:  Vehicle loops and loop detectors are also frequently used as safety devices. Loop detectors are wired or plugged directly to the gate operator or overhead door. Loops are buried directly under the automated gate or door. When a vehicle, or oth...

What is a LOOP? Loop Installation?

What is a LOOP? A loop sensor is a detector that senses a change in inductance caused by the passage of a vehicle near the sensor. It is used to manage traffic flow. Vehicles passing over or stopped within the detection area of an inductive-loop detector decrease the inductance of the loop. The electronics unit senses this event as a decrease in frequency and sends a pulse to the controller signifying the passage or presence of a vehicle. Loop Installation? Traffic Counting Loops are installed in the surface asphalt of secondary roads, highways, freeways & freeway ramps. The number of loops per location varies from 1 (on a single lane ramp) up to 8, 10 or more on a multi-lane freeway. The dimensions of a loop are dependant on the exact requirements from Ministry of Transportation, Ontario, Region or Municipality requesting the work. In order to install the loops Highway Technology requests permission to close the lane or lanes in which the work is to t...

Inductive Loop Detector works by detecting an inductance change in wire loop (coil) that is buried in road

 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...
