Remote real-time vehicle exhaust emission monitoring device

Abstract

The invention discloses a remote real-time vehicle exhaust emission monitoring device which comprises an MCU (microprogrammed control unit) main control module, a GPS (global positioning system) positioning module, a GSM (global system for mobile communications) text message alarm module, an SD (secure digital) memory card storage module, a liquid crystal display module, a data acquisition module and a power module, wherein the data acquisition module is connected with the MCU main control module, the GPS positioning module is connected with the MCU main control module through a serial port 1, the MCU main control module is connected with the GSM text message alarm module through a serial port 2, the MCU main control module is further connected with the SD memory card storage module through an SPI (serial peripheral interface), and the MCU main control module is further connected with the liquid crystal display module and the power module. The remote real-time vehicle exhaust emission monitoring device enables detection personnel to detect any vehicle driven on a road anywhere with the aid of a monitoring screen in an office and is insusceptible to objective conditions such as weather, and labor intensity of the detection personnel can be also improved.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a remote real-time vehicle exhaust emission monitoring device. Background technique [0002] With the improvement of people's living standards, automobiles have entered the lives of ordinary people, and the number of automobiles has increased rapidly. The ensuing tail gas emission is becoming more and more serious to the environment pollution. Scientific analysis shows that automobile exhaust contains hundreds of different compounds, among which pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead, and sulfur oxides. The harmful exhaust gas emitted by a car in a year is three times larger than its own weight. The British Association for Clean Air and Environmental Protection once published a research report saying that compared with the victims of traffic accidents, the number of people who die from air pollution in the UK ...

AI Technical Summary

Problems solved by technology

[0003] How to detect automobile exhaust emissions and better prevent and control environmental pollution is a matter of great concern and attention to the successive governments and the entire society. Existing automobile exhaust emission instruments are large in size, heavy in weight, and require an external AC power supply, which is difficult to do. For real-time detection on the road, only fixed detection points can be set up, lacking randomness and immediacy, and the detection of the exhaust gas purification device must be carried out under working conditions. The current working condition test requires a bench test, and the price of the test equipment ranges from five to six. 100,000, as many as several hundred, tens of millions, and the cost of doing an exhaust gas purification device test is also very high

Many production and research units do not have the ability to test products frequently
