Information

It is aimed at the phenomenon that the vehicle fails to deduct the fee due to "the following distance being too close" or non-ETC vehicles entering by mistake. GTEK's relevant technical engineers have carried out corresponding technical upgrades on the light curtain in response to this situation and launched the LHN (C) vehicle separation light curtain, which effectively solved the problems of vehicle interference and improved the speed and reliability of vehicles.

 

Vehicle separation light curtain, also called vehicle separation grating, is specially designed for vehicle separation and detection in the highway (ETC) automatic toll collection systems. The technology is mature and eliminates the phenomenon of following vehicles, and can reliably separate semi-trailers, trailers, and single vehicles. Ensure that the weighing data corresponds to the vehicle one by one.

 

At present, GTEK's vehicle separation light curtain can be used both indoors and outdoors. Easy to align, the light curtain has a built-in electric heating glass window, with automatic heating and defrosting function; in good weather, the accuracy of separation judgment is high; the protective shell has electric heating glass, with temperature control, effective anti-fog and anti-frost and other bad weather. The grating adapts to the ambient temperature: -45-80°C; ambient humidity: RH≤95%. And it can provide a variety of options for stainless steel windproof covers to meet the budgetary needs of vehicle separation light curtains at highway intersections and weighbridges.

 

 

Working principle of vehicle separation light curtain.

A vehicle separation light curtain is also called an infrared vehicle separator. It is mainly composed of a transmitter and a receiver, which are relatively placed on both sides of the toll-by-weight lane, and are responsible for judging whether the vehicle passes through the lane completely. The working principle of the LHN(C) series infrared vehicle separation light curtain is to realize the synchronous scanning of the vehicle through the infrared light emission and reception of the non-contact linear arrangement, and convert the optical signal into an electrical signal, to realize the comprehensive detection of vehicle data. Compared with other detection technologies, LHN(C) series infrared vehicle separation light curtain products have mature technology, easy installation, high-speed response, and strong anti-interference. It can output rich vehicle data information, can reliably detect various special vehicles, and can eliminate the phenomenon of car following.

 

 

The vehicle separator at the toll station is used outdoors, so it is generally used together with a protective cover made of 304 stainless steel. Protect the vehicle separation light curtain, and built-in electric heating glass window, when the penetration of the vehicle separator decreases due to rain and snow, the electric heating system will automatically start using optical communication technology to realize synchronous scanning between the transmitter and receiver. To ensure the normal operation of infrared vehicle detectors in ETC high-speed toll stations.

 

ETC high-speed toll station vehicle separation light curtain composition.

◆Transmitter and receiver: The transmitter has a built-in high-energy light-emitting element in a linear arrangement, and the receiver has a built-in receiving element with the same number as the transmitter. The corresponding photoelectric elements of the transmitter and receiver are sequentially triggered synchronously to detect whether the optical path is conducting. When a car passes through the scanning area, some or all of the beams are blocked and thus detected.

◆Protective cover: stainless steel material, providing protection for the separator, built-in electric heating glass. Automatic heating is realized when the temperature is too low to ensure reliable use of the vehicle separator in wet areas, rainy and foggy weather, and cold seasons.
