DQSM系列車輛分離光幕：

産品配置：1.發射器和接收器：發射器內置線性排列的高能量發光元件，接收器內置與發射器數量相同的接受元件，發射器和接收器的對應光電元件依次按順序同步觸發，檢測光路是否導通，當汽車通過掃描區域時，部分或全部光束被遮擋，因而被檢測出。

               2.控制单元：调取并处理发射器/接收器的同步扫描信号，同时检测光幕工作状态，提供多种输出信号，如：开关量输出、串口输出或模拟量输出。考虑到系统的可靠性和安装的简便性，市场上普遍使用的车辆分离光幕都是控制器内置的两箱式产品，而没有独立的外置控制器。

               3.电缆线：连接发射器/接收器与控制器的接插电缆，一般长度为5—10m。

               4.防护外罩：为不锈钢或铝合金材料，为分离器提供防护，内置电加热玻璃、温度控制器、湿度控制器，在湿度过高、温度过低时实现自动加热，以保证车辆分离器在潮湿地区、雨雪天气、寒冷季节可靠使用。

産品特點：1.集成化設計、無需控制器，簡單易用；

               2.光幕高度：50mm到2840mm；

               3.光軸間距：10、14、20、25、30、40、80mm七种，其他间距可以定做；

               4.检测距离：0—5米，0—10米；

               5.LED指示灯可显示光幕的工作状态及故障状态；

               6.双NPN输出：#输出1：车辆检测信号输出；#输出2：光幕故障报警输出；

               7.运用独特算法，使光幕只检测150mm以上的物体，同时具有1mm的分辨率，既可以避免由阳光、飞、鸟、蚊虫及污泥引起的误动作，也可以可靠检测车辆挂钩；

               8.自动检测故障，并忽略（屏蔽）有问题的光束，仍能保持正常工作，同时输出报警信号；

               9.使用高能量、高穿透率光电管，便于安装维护；

              10.可以实现车辆自动分离、计数、存在检测、分类检测、确定车头时距；

              11.完全消除跟车现象，将半挂车、全挂车、单车可靠分离；

              12.专用防护外壳使用坚固的铝型材制成，保证车辆分类光幕可靠用于室外的恶劣环境；

              13.适用温度：-10℃—55℃；环境湿度：RH≤85%（20℃）

DQSM series vehicle separation screen:
Product configuration: 1. transmitter and receiver: high energy light emitter built-in linear array, the same number of built-in receiver receiving element and corresponding transmitter, photoelectric element transmitter and receiver are orderly synchronized trigger detection optical path is switched on, when the car passes through the scanning area, all or part of beam is blocked, so it is detect.
                               2. control unit: synchronous scanning signal processing and retrieval of transmitter / receiver, and inspection work, to provide a variety of output signals, such as switch output, serial output or analog output. Considering the simplicity and reliability of the installed systems, vehicle separation screen is widely used on the market are two box products built-in controller, without external controller independent.
                               3. cable: connect the transmitter / receiver and controller connector cable, the general length is 5 - 10m.
                               4. the protection cover is stainless steel or Aluminum Alloy materials, to provide protection for the separator, a built-in electric heating glass, temperature controller and humidity controller, the humidity is too high, too low temperature of automatic heating, to ensure that vehicles separator in humid areas, rain and snow, cold season and reliable.
Features: 1. integrated design, no controller, easy to use;
              2. screen height: 50mm to 2840mm;
              3. optical axis spacing: 10, 14, 20, 25, 30, 40, 80mm seven kinds, other spacing can be made to order;
              4. detection distance: 0 - 5 meters, 0 - 10 meters;
              5.LED indicator shows the working state and fault state of the screen;
              6. double NPN output: # output 1: vehicle detection signal output; output: 2 # screen fault alarm output;
              7. the use of the unique algorithm, the screen only detected more than 150mm objects, with a resolution of 1mm, which can be avoided by the sun, bird, fly, mosquito and sludge caused by misoperation, can reliably detect vehicle hook;
              8. automatically detect faults and ignore (shielded) problematic light beams that still function properly while outputting an alarm signal;
              9. use high energy and high penetration photoelectric tube for easy installation and maintenance;
             10. automatic separation, counting, detection, classification and determination of vehicle headway can be realized;
             11. completely eliminate car following phenomenon, the semi-trailer, full trailer, bicycle reliable separation;
             12. special protective shell using aluminum made of sturdy, reliable guarantee for vehicle classification screen to the harsh outdoor environment;
Suitable temperature: -10 13. C and 55 C; humidity: RH = 85% (20 C)
