Problems solved by technology

However, the working status of the vehicle emission control post-processing device directly affects the level of vehicle pollutant emissions; the failure of the vehicle emission control post-processing device to work or work in an abnormal state will greatly increase the content of pollutants in the vehicle exhaust
In response to this situation, two monitoring methods, manual inspection and on-board diagnostic system, are currently mainly used, but both lack effective supervision, which is not conducive to timely troubleshooting of vehicle emission control post-processing device failures

Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039] Such as Figure 1-3 As shown, this embodiment provides a monitoring system for automotive emission control post-processing devices, including a differential pressure sensor 2 , a temperature sensor 1 , a sampling unit 3 , a control unit 4 , a server 5 , and a monitoring terminal 6 .

[0040] The pressure difference sensor 2 is used to detect the exhaust pressure difference between the upstream and downstream of the vehicle emission control post-processing device, and the temperature sensor 1 is used to measure the exhaust temperature and pressure difference sensor at the set position of the post-vehicle emission control post-processing device. Proper location of emission control aftertreatment devices figure 2 It is a preferred installation method. The temperature sensor includes a front temperature sensor and a rear temperature sensor, which are installed on the i...

Abstract

The invention discloses a monitoring system and method for a vehicle emission control aftertreatment device. The monitoring system comprises a pressure difference sensor, a temperature sensor, a sampling unit, a control unit, a server and a monitoring terminal, the input end of the sampling unit is connected with the pressure difference sensor and the temperature sensor, and the output end of the sampling unit is connected with the control unit. The control unit comprises a data processing chip, an OBD communication module, a wireless communication module, a GPS module and a display module, the data processing chip is connected with the OBD communication module, the wireless communication module, the GPS module and the display module, and the OBD communication module is connected with a vehicle OBD interface. The data processing chip is connected with the server through the wireless communication module, and the monitoring terminal is connected with the server. The monitoring system can serve as a basis of the government for treating motor vehicle pollution and punishing illegal emissions, a driver is supervised and urged to normatively use a vehicle, and pollutant emissions are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile emission control, in particular to a monitoring system and method for an aftertreatment device of automobile emission control. Background technique [0002] With the rapid development of my country's automobile industry, my country's urban air began to show the characteristics of combined pollution of soot and motor vehicle exhaust, which directly affects the health of the masses; Motor vehicles emit 45.473 million tons of pollutants. Automobiles are the main contributor to the total amount of pollutants. The emissions of NOx and PM exceed 90%, and HC and CO exceed 80%. Vehicle emissions have become an important source of air pollution in my country. It is an important cause of haze and photochemical smog pollution. The urgency of automobile pollution prevention and control has become increasingly prominent. The government work report clearly stated that "strengthen the comprehensive prevention ...
