It includes a first infrared light sensor and a second infrared light sensor separated by a front and rear arrangement. The first infrared light sensor and the second infrared light are perpendicular to the ground and accurately control each lane. The exhaust spectrum module is used to measure the impact of vehicle exhaust on transmitted light, and includes a telemetry host transmitter fixed on the gantry and a ground-mounted reflector. The central processing module is used to process data from the infrared monitoring module, exhaust gas spectrum module, central processing module, weather collection unit and vehicle collection unit, and the central processing module transmits data to and from the above components; The weather collection unit is used to detect environmental parameters, including real-time detection driven by an infrared detection module and intermittent detection in parallel. The infrared detection module immediately detects the environment when a vehicle passes by and sends the detection results to the central processing module. When there are many vehicles, the single detection time of the weather collection unit is used as a cycle. The detection results of the current cycle are used within the cycle, and the detection results of the next cycle are used outside the cycle. The vehicle collection unit is used to collect vehicle parameters. The network transmission unit is used to upload the results of the central processing module to the network, and the network transmission unit and the central processing module data are transmitted; The large-screen display unit is used to display the test results, and the large-screen display unit transmits data to the network transmission unit; The environmental monitoring platform, the user unit of the present invention, makes decisions based on the detection results.

[0020] The first infrared sensor is normally open and used to monitor whether a vehicle enters the detection area. The second infrared sensor is controlled by the first infrared sensor. The first infrared sensor blocks the infrared radiation to detect vehicle entry, and the second infrared sensor is activated to sense vehicle entry. The first infrared sensor is normally open and used to monitor whether a vehicle enters the detection area. The second infrared sensor is controlled by the first infrared sensor. When the first infrared sensor detects a vehicle entry, it blocks the infrared radiation and the second infrared sensor is activated. The vehicle is detected to be in the detection area. If the second infrared sensor is not blocked within a specified time after the first infrared sensor is blocked, it is determined that no vehicle has entered. If the second infrared sensor is also blocked within a specified time after the first infrared sensor is blocked, it is determined that a vehicle has passed.

[0021] The exhaust spectrum module is arranged between the first infrared light sensor and the second infrared light sensor, and the exhaust spectrum module is controlled by the infrared monitoring module. The telemetry host transmitting device generates red and ultraviolet rays that pass through the exhaust gas to irradiate the reflecting device, and the red and ultraviolet rays are reflected by the reflecting device to the telemetry host transmitting device. The telemetry host transmitting device transmits a light source to send ultraviolet light and infrared light to the reflecting device under the road, and the reflecting device will reflect it to the telemetry host transmitting device. When the car passes through these light beams when driving on the road, the exhaust gas of the car absorbs the light and changes the intensity of the transmitted light. The exhaust gas of the motor vehicle is monitored by the change of light intensity in the detector. When the vehicle passes, the exhaust gas will be discharged into the atmosphere, which will interfere with the infrared and ultraviolet rays. Infrared light is used to detect CO2, CO and HC, and ultraviolet light is used to detect NOx emissions.

[0023] The vehicle collection unit includes a laser speed measuring device for detecting vehicle speed and a vehicle photographing device for vehicle sampling. The vehicle photographing device includes a front-end photographing device arranged at the front end of the infrared monitoring module and a rear-end photographing device arranged at the rear end of the infrared monitoring module. The rear-end photographing device is provided in all lanes. The front-end photographing device and the laser speed measuring device are used separately to detect vehicle information and vehicle speed, and send them to the central processing module.

[0024] The central processing module collects and processes data from all front-end facilities, including the infrared monitoring module, exhaust gas spectrum module, central processing module, meteorological collection unit and vehicle collection unit.

[0025] The central processing module works as follows: Spectral data of the exhaust gas spectrum module; The deviation value of the wind speed and direction of the wind monitoring device from the air mass is, in principle, to reduce the standard number of unqualified data; The impact value of the haze monitoring device on the haze red ultraviolet rays is based on the standard gas environment. If it is greater than the benchmark book, the standard number of unqualified data will be reduced, and if it is less than the benchmark number, the standard number of unqualified data will be increased; The impact value of the temperature and humidity data collected by the temperature and humidity collection device on the environment is based on the standard environmental value. If it is greater than the benchmark value, the standard number of unqualified data will be reduced, and if it is less than the benchmark value, the standard number of unqualified data will be increased; The vehicle speed result monitored by the vehicle collection unit is based on the standard vehicle speed. If the speed is greater than the standard speed, the number of unqualified data standards will be reduced, and if it is less than the standard speed, the number of unqualified data standards will be increased; Comprehensive calculation to judge the quality of exhaust gas; In this embodiment, a first infrared sensor is normally on to monitor whether a vehicle has entered the detection area. When the first infrared sensor detects vehicle entry, it blocks infrared radiation, and the second infrared sensor is activated. This senses vehicle entry. If the second infrared sensor remains unblocked within a specified period after the first infrared sensor is blocked, it is determined that no vehicle has entered. If the second infrared sensor is also blocked within a specified period after the first infrared sensor is blocked, it is determined that a vehicle has passed. The meteorological detection unit is activated to monitor the environment, and the laser speed measurement device is activated to measure the vehicle's speed. When the blockage of the first infrared sensor is no longer blocked, it is determined that the vehicle has completely entered. When the blockage of the second infrared sensor is no longer blocked, it is determined that the vehicle has completely exited. The spectral detection module is activated to monitor the area between the first and second infrared sensors. The detection results are then transmitted to the central processing module, which performs comprehensive calculations and transmits the results to the environmental detection platform and large-screen display module via the network transmission module, notifying the detected and detecting parties of the results. The detection results are then determined by the entire environmental detection platform, enabling accurate detection results to be presented, enabling decision makers to make scientific and accurate decisions.
