Abstract

The invention provides a high-emission vehicle comprehensive integrated monitoring Internet of Things device which comprises a detection probe (3), a control assembly (2) and a connecting pipe (1), wherein the detection probe (3) and the control assembly (2) are arranged at the two ends of the connecting pipe (1) respectively; at least one detection ring (4) is arranged on the outer surface of the detection probe (3); each detection ring (4) is arranged in an inner cavity of a gas collecting tube (5); a gas inlet and a gas outlet of the gas collecting tube (5) are arranged along the length direction of the detection probe (3); and the size of the gas inlet of the gas collecting tube (5) is larger than that of the gas outlet of the gas collecting tube (5). According to the invention, it can be ensured that the collected automobile exhaust fully contacts the detection ring (4) after being converged in the gas collecting pipe (5), so that the detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an Internet of Things device for comprehensive and integrated monitoring of high-emission vehicles. Background technique [0002] With the increasing demand for environmental protection supervision, the supervision of non-road mobile machinery and other high-emission vehicles needs to be solved harshly. Relevant surveys and studies have shown that high-emission vehicles such as non-road mobile machinery are one of the important reasons for haze weather. High-emission vehicles such as non-road mobile machinery have harsh working conditions, large loads, and drastic changes in working conditions, which require high reliability and economy of the engine. In addition, they are widely distributed in space, and it is difficult to detect and monitor their exhaust emissions. Big. Existing monitoring equipment for high-emission vehicles such as off-road mobile machinery...
