In the first half of this year, Fuzhou will be able to achieve vehicle exhaust telemetry, and measure the exhaust emission value of driving vehicles within 1 second. The reporter learned yesterday that the vehicle exhaust fixed telemetry monitoring system, which citizens have been looking forward to for for a long time, has been determined to be located opposite the bus station at Houban junction of South Second Ring Road. The equipment has been installed and is being debugged. Roadside detection vehicle exhaust equipment Three factors for site selection Tail gas telemetry system is fixed and mobile. Fuzhou currently adopts fixed equipment, and a set of equipment is worth more than 200 million yuan. At present, this equipment has been installed in the direction of the South Second Ring Road to the White Lake Pavilion, opposite the bus station at the back ban intersection. There are three considerations for choosing here.” According to the law enforcement officer of Fuzhou environmental protection bureau, first of all, the traffic flow should be large enough, and the South Second Ring Road just meets this condition. Secondly, this is just the uphill section, “when the car goes uphill, it plus-sized the throttle, and the exhaust emissions are relatively large, which is conducive to screening polluted vehicles.” The last thing to consider is the construction conditions, “there must be a place to place equipment and be able to lay lines, etc.” According to reports, this is Fuzhou’s first tail gas telemetry system, which will be promoted according to the situation in the future. The reporter visited the scene a few days ago and saw two “Iron Box” on the green belt “. The staff explained that this is the “brain” of the system, which is a vehicle exhaust Telemeter. The two “Iron box” will transmit and receive infrared rays, etc. The car passes through the “iron box, within 1 second, the exhaust emission information can be detected. Find out “squid cars” and urge maintenance or re-inspection Environmental law enforcement officials said that the current methods of road inspection and exhaust gas monitoring are sampling in the exhaust pipe and then using conventional instruments for analysis. Only 30 to 40 vehicles can be checked in one morning. In contrast, by using telemetry, high-emission vehicles can be quickly found, and thousands of vehicles can be detected by fixed remote sensing monitoring points a day, with an efficiency more than ten times that of traditional methods. How will the Environmental Protection Department use the telemetry system to control the exhaust gas? According to law enforcement officers of Fuzhou environmental protection bureau, telemetry system is conducive to screening vehicles with high emission and high pollution. “Through this equipment, we can screen, judge and find out vehicles with high pollution and emission, such as the ‘Squid cars’ frequently reported by Haidu newspaper, and urge them to maintain or re-inspect the vehicles, so as to effectively reduce vehicle exhaust pollution.” (Haidu reporter Chen Wenhao/Wen Huang Kong Yu/picture)
