Embodiment Construction
[0032] Let's take an actual scene as an example. The system includes four road sections A, B, C, and D in a city, involving people E, F, G, and H. in. Specific steps are as follows:
[0033] Step 1: Install and place all the devices of the system. In road sections A, B, C, and D, it is recommended to place the gas monitoring nodes in the flowerbeds on both sides of the road, adjust the height to 50cm above the ground, package the monitoring nodes, and place the converging nodes next to the traffic lights. The whole system is adjusted to the working state, the vehicle is driving on the road, the exhaust gas (carbon monoxide) is diffused and enters the air hole of the monitoring node on the roadside, and the gas sensor converts the gas concentration into an electron flow to generate concentration data The data is sent to the aggregation node, and the aggregation node next to the road transmits the data to the background server. The background software stores, processes, and a...
