ITS50激光交調系統(tǒng),采用激光非接觸式精準測量,通過測量區(qū)域機動車的車高、車速、車長、車身輪廓來對機動車進行自動模型比對精確分型(可按交通運輸部Ⅰ、Ⅱ類車標準分型),同時按《交調設備相關技術要求、管理辦法及外場檢測操作實施細則》中規(guī)定的 I 級設備要求,將車頭時間、車速、車長、9 類車型號由激光器直接以 RS-485 輸出,以供中心計算車流量、地點車速、車頭時距、跟車百分比、車頭間距 、時間占有率等交通情況調查數據。
ITS50 laser Intermodulation system, using laser non-contact precision measurement, By measuring the vehicle height, speed, length, and body profile of the motor vehicle in the area, the motor vehicle is automatically modeled(according to the standard types I and II of the Ministry of Transport). At the same time, according to the requirements of Class I equipment stipulated in the "Technical Requirements for Intermodal Equipment, Management Measures, and Implementation Rules for Outfield Detection Operations," the front time, speed, length, and type 9 vehicles are directly exported by the laser to RS-485. The center is used to calculate traffic survey data such as traffic flow, location speed, time distance from the front of the car, percentage of the car, distance from the front of the car, and time share.
本系統(tǒng)和方法屬于非接觸方式,安裝頂置激光器即可。系統(tǒng)結構簡單,操作方便,成本較低。
The system and method belong to the non-contact mode, the installation of the top laser can be. The system has simple structure, convenient operation and low cost.
