Brief introduction

Tunnel is a special kind of tubular structures, due to the small space, with a closed characteristics, the tunnel's vehicle emissions exhaust gas, such as timely and reasonable emission out, resulting in the aggregation of CO and suspended particulate matter, is directly related to, the vehicles in the tunnel of our passengers and maintenance staff safety. To the tunnel visibility and CO concentrations of all-weather monitoring, in a timely manner in order to start the fan forced ventilation and take other corresponding measures, automation of the Vico detection instrument in modern traffic is indispensable testing equipment.

HY-VICO series is designed to collect VI/CO data online, provide to the traffic control department, to provide decision-making basis for tunnel ventilation and road safety.

HY-VICO detector according to the transmission principle and transmit / receiver and a reflector mounted opposite, fixed by the frame alignment, optical components to give the highly focused beam become a test beam, installation distance 3 meters (round-trip double optical path, actual detection optical path for 6 meters), attenuation due to dust, the receiver signal is obtained after treatment to measure value. According to the requirement of the design code for ventilation and lighting of highway tunnel, the top or side wall of the tunnel is installed.

The intelligent detection instrument with compensation function, the optical lens in the pollution situation, can automatically gain compensation, thus ensuring a long maintenance cycle.

Features

Visibility (VI) and carbon monoxide (CO) can be measured at the same time;

High resolution visibility measurement;

Effect of measurement without other stray light;

Specially aimed at the tunnel bad environment design;

Effectively avoid the environment, the past caused by vehicle vibration can not be measured;

Installation, start-up, maintenance costs low;

Instrument with state display, fault alarm and data storage function, easy to debug and equipment maintenance;

Multiple output mode, data acquisition is convenient;

The compensation function is unique, ensure a longer maintenance period;

Non contact and continuous monitoring of visibility;

Using the latest microprocessor technology, fully digital operation.
