Dqlv Vehicle Separation Light Curtain
Product configuration
1. Transmitters and receivers: Transmitters have linearly arranged high-energy light-emitting elements, receivers have the same number of receiving elements as transmitters. The corresponding optoelectronic elements of transmitters and receivers are triggered synchronously in sequence to detect whether the light path is on or not. When the car passes through the scanning area, some or all of the beams are occluded and thus detected.
2. Control Unit: Bead and process the synchronous scanning signal of transmitter/receiver, detect the working state of the light screen, and provide a variety of output signals, such as switching output, serial output or analog output. Considering the reliability of the system and the convenience of installation, the vehicle separating light curtain commonly used in the market is a two-box product built in the controller, but there is no independent external controller.
3. Cable: Connect the cable between transmitter/receiver and controller. The default length is 5m.
4. Protective cover: for stainless steel or aluminium allov materials, to provide protection for separators, built-in electric heating glass. temperature controller, humidity controller, when the humidity is too high, the temperature is too low to realize automatic heating, in order to ensure the reliable use of vehicle separators in wet areas, rain and snow weather. Cold season.
Product characteristics
1.Integrated design, no controller, simple and easy to use.
2.Light curtain height:60mm-2840mm;
3. Light screen spacing: 10, 14, 20, 25, 30, 40, 80 mm, other spacing can be customized;
4.Detection distance:0-5m,0-10m,0-130m;
5. The LED indicator can display the working state and failure state of the light screen.
6.Dual NPN output:
# Output 1:Vehicle detection signal output;
# Output 2:Output of light screen fault alarm;
7.Using a unique algorithm, the light curtain can detect only objects over 150 mm with a resolution of 1 mm, which can avoid the misoperation caused by sunlight, birds, mosquitoes and sludge, and also can reliably detect vehicle hooks.
8. Automatically detect faults and ignore shield) faulty beams. still can maintain normal operation. while outputting alarm signals;
9. Use high-energy and high-penetration photovoltaic cells for easy installation and maintenance.
10. Automatic separation, counting, presence detection, classification detection and determination of headway can be realized.
11. Completely eliminate the phenomenon of car-following and reliably separate semi-trailer, full-trailer and bicycle.
12. The special protective shell is made of solid aluminium profiles to ensure that the vehicle light separation screen is reliably used in outdoor harsh environment.
13. Applicable temperature: -10C--55C: Environmental humidity: RH<85%(20C)
Working principle
The working principle of the vehicle separation light curtain is to realize synchronous scanning of the vehicle through linearly arranged infrared light transmission and reception, and convert the optical signal into an electrical signal, thereby realizing comprehensive detection of vehicle data, compared with other detection technologies.
Infrared vehicle detection products are mature in technology, easy to install, high-speed response, strong anti-interference, can output a wealth of vehicle technical information, and can reliably detect various special vehicles. Infrared vehicle scanning system is mainly used for: general road toll station, non-stop toll collection system (ETC), automatic vehicle classification system (AVC), highway weight collection system (WIM), fixed over-limit detection station, customs vehicle management system, etc.
Technical parameters of protective cover
Protective cover
Spray plastic material for stainless steel and cold steel plate, provide protection for light curtain, built-in electric heating glass, temperature controller, humidity controller, realize automatic heating when humidity is too high and temperature is too low, in order to ensure the reliable use of vehicle separation light curtain in wet areas, rain and snow weather.cold season.
It is widely used in intelligent transportation system, highway toll collection system non-stop toll collection system, highway weighing system, over-limit detection system and other traffic control systems. Le use of vehicle separators in wet areas rain and snow weather.cold season.
★ It is specially used for detecting the light curtain when it is installed outdoors to protect the light curtain from impact damage.
★ Built-in electric heating glass can be automatically heated.
★ Internal temperature automatic control, when wet or heavy rain and fog vapor, automatic removal of snow and rain on the glass surface;
★ Box material: stainless steel, cold rolled steel plate, aluminum alloy, etc.
★ Antifogging glass: electric heating wire plus wire safety tempered glass. power 200W/set,power supply 24VDC;
★ Start heating when the temperature is lower than C (can be set on site); start heating when humidity is above 96% (can be set on site);
★ Overheat protection control: disconnect the heating when the temperature is higher than 45 ℃.
