EmailThe mobile vehicle exhaust telemetry system independently developed by our company is suitable for urban road mobile monitoring and single-lane fixed monitoring. The detection of CO, CO2, NO, HC, opaque smoke and light absorption coefficient in gasoline and diesel vehicle exhaust is realized by tunable semiconductor laser absorption spectroscopy technology, ultraviolet differential absorption spectroscopy technology, green laser transmission principle and high-definition image recognition technology, the response time is fast (less than 0.5s), and the system operation is simple. The remote sensing monitoring method is used for monitoring, which does not affect the normal driving of the vehicle, avoids the interference and uncertainty caused by sampling, and the monitoring results are objective and true. The measurement signal is transmitted through WI-FI, and an external LED display can be connected to display the exhaust emission information of the vehicle.
Accurate monitoring results: Longitudinal multi-point identification of vehicle position, accurate capture of exhaust gas
mass monitoring
High monitoring efficiency: Telemetry measurement method, does not affect vehicle driving, fast response (less than 0.5s)
Independent research and development of core technology: TDLAS and UV-DOAS monitoring technology developed with
independent property rights
Efficient on-site layout: Using a unique optical path adjustment module, on-site layout can be completed in a very short
time
Compact and lightweight: Highly integrated design, compact and lightweight, more conducive to mobile operation
Integrated calibration system: Four components (CO, CO2, HC, NO) can be automatically calibrated, the operation is
simple and convenient, and the work efficiency is high
Real-time data matching: Real-time output of monitoring results, without post-processing, can directly screen vehicles with
excessive emissions
Automatic recording and storage: Real-time recording of running status data, power failure does not affect data storage
