Detailed ways

The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Apparently, the described embodiments are only some embodiments of the utility model, not all embodiments.

Embodiment 1: As shown in Figures 1 to 4, a mobile exhaust gas monitoring device includes a main control module, a GPRS communication module, a laser emitting device, a reflecting device, a detection receiving device, a gas detection and analysis module, a power supply module, a camera module and Convolutional Neural Network Module. The main control module, laser emitting device, detection and receiving device, gas detection and analysis module, power supply module, camera module and convolutional neural network module are all integrated on the main body, and the main body is arranged as a movable box structure.

As shown in FIG. 3 , on the front, rear, left, and right sides of the main body 1 , a laser emitting device 2 and a detecting and receiving device 3 are respectively provided.

As set up above, the utility model is relatively compact overall, takes up little space, and is convenient for mobile installation.

As shown in FIG. 4 , the main body 1 is placed at the center of the intersection, and the reflection devices 8 are respectively installed at the middle positions of the four intersection edges, facing the laser emitting device 2 on the corresponding surface of the main body 1 . The mobile tail gas monitoring device uses tunable laser absorption spectroscopy technology to detect tail gas components.

As shown in FIG. 3 , the mobile exhaust gas monitoring device is respectively equipped with connecting rods 5 with adjustable length and direction on four surfaces, and the camera module 6 is mounted on the connecting rods.

Further, the present utility model can also be provided with a button module, an LED driver module and an LED dot matrix 4 . Three-color LED dot matrixes can be installed on the four panels of the main body. When the traffic lights fail or are temporarily needed, the traffic lights can be activated through the key module on the main body.

Furthermore, the power module of the present invention is composed of a solar panel 7 , a mains interface, a charging module, a storage battery and a DC conversion module, and the solar panel 7 is arranged on the top of the main body 1 .

The utility model can utilize solar power to supply power like this, also can use commercial power. In order to prevent power outages, storage batteries are set up and used during power outages. The DC conversion module converts AC power to DC power for use by the module.

When the utility model starts to work, the laser emitting device continuously emits laser signals, which are reflected by the reflecting device to the detecting and receiving device. If the detection and receiving device does not receive the reflected signal, it means that there is a car entering. The main control module controls the gas detection and analysis module to continuously read the signal received by the detection and receiving device. If the value exceeds the threshold, the main control module controls the high-speed camera to take pictures of the vehicle . And through the convolutional neural network module (CNN module), the pictures captured by the high-speed camera are processed to obtain the license plate and vehicle information, and then sent to the supervision department through the GPRS module.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
