What Is a Vehicle Separation Light Curtain? How Does It Work?
The vehicle separation light curtain is specially designed for vehicle separation detection in the highway (ETC) automatic toll collection system. The mature technology completely eliminates the phenomenon of following vehicles, reliably separates semi-trailers, full trailers, and single vehicles, and ensures a one-to-one correspondence between weighing detection data and vehicles. So which vehicle separation light curtain is better?
What is a Vehicle Separation Light Curtain？
The vehicle separation light curtain transmits and receives infrared light in a linearly arranged configuration to achieve synchronous scanning of the vehicle. It then converts the light signal into an electrical signal, enabling comprehensive detection of vehicle data. Compared to other detection technologies, infrared vehicle detection products have a mature technology, are easy to install, have a high-speed response, strong anti-interference capabilities, and can output a wealth of vehicle technical information. They can reliably detect a variety of special vehicles. The infrared vehicle scanning system is used in a variety of applications, including general highway toll booths, non-stop toll collection systems (ETC), automatic vehicle classification systems (AVC), highway weighing systems (AVC), highway weighing and charging systems (WIM), fixed over-limit detection stations, customs vehicle management systems, and more.
What Are the Components of a Complete Vehicle Separation Light Curtain?
1. Transmitter and receiver
Transmitter and receiver: The transmitter has built-in linearly arranged high-energy light-emitting elements, and the receiver has built-in receiving elements with the same number as the transmitter. The corresponding photoelectric elements of the transmitter and the receiver are triggered synchronously in sequence to detect whether the light path is conductive. When the car passes through the scanning area, part or all of the light beam is blocked and thus detected.
2. Controller
Read and process the synchronous scanning signal of the transmitter/receiver, detect the working status of the light curtain at the same time, and provide a variety of output signals, such as: switch output, serial port output or analog output. Considering the reliability of the system and the ease of installation, the commonly used vehicle separators on the market are two-box products with built-in controllers, without independent external controllers.
3. Protective cover
It is made of stainless steel or aluminum alloy material to provide protection for the separator. It has built-in electric heating glass, temperature controller, and humidity controller to achieve automatic heating when the humidity is too high and the temperature is too low, so as to ensure the reliable use of the vehicle separator in humid areas, rainy and snowy weather, and cold seasons.
4. Cable
Connector cable connecting the transmitter/receiver and the controller
