DQSM系列車輛分離光幕：

產品配置：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.控制單元：調取并處理發射器/接收器的同步掃描信號，同時檢測光幕工作狀態，提供多種輸出信號，如：開關量輸出、串口輸出或模擬量輸出。考慮到系統的可靠性和安裝的簡便性，市場上普遍使用的車輛分離光幕都是控制器內置的兩箱式產品，而沒有獨立的外置控制器。

               3.電纜線：連接發射器/接收器與控制器的接插電纜，一般長度為5—10m。

               4.防護外罩：為不銹鋼或鋁合金材料，為分離器提供防護，內置電加熱玻璃、溫度控制器、濕度控制器，在濕度過高、溫度過低時實現自動加熱，以保證車輛分離器在潮濕地區、雨雪天氣、寒冷季節可靠使用。

產品特點：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七種，其他間距可以定做；

               4.檢測距離：0—5米，0—10米；

               5.LED指示燈可顯示光幕的工作狀態及故障狀態；

               6.雙NPN輸出：#輸出1：車輛檢測信號輸出；#輸出2：光幕故障報警輸出；

               7.運用算法，使光幕只檢測150mm以上的物體，同時具有1mm的分辨率，既可以避免由陽光、飛、鳥、蚊蟲及污泥引起的誤動作，也可以可靠檢測車輛掛鉤；

               8.自動檢測故障，并忽略（屏蔽）有問題的光束，仍能保持正常工作，同時輸出報警信號；

               9.使用高能量、高穿透率光電管，便于安裝維護；

              10.可以實現車輛自動分離、計數、存在檢測、分類檢測、確定車頭時距；

              11.消除跟車現象，將半掛車、全掛車、單車可靠分離；

              12.專用防護外殼使用堅固的鋁型材制成，保證車輛分類光幕可靠用于室外的惡劣環境；

              13.適用溫度：-10℃—55℃；環境濕度：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)
