Vehicle remote monitoring terminal based on various sensors

Abstract

The invention provides a vehicle remote monitoring terminal based on various sensors. The terminal comprises a power supply management module, a GPRS module, a GPS module, an SD card module, an analogsignal processing module, a digital signal processing module, a communication module, a hardware watchdog module, and a microcontroller module. According to the terminal, vehicle real-time data acquisition and monitoring can be realized, and the condition of practical operation of a diesel engine and the NOX concentration and the particulate matter concentration level in exhaust can be monitoredin real time. Real-time monitoring and data acquisition of information including the NOX concentration, the particulate matter concentration level, the SCR work efficiency, and the DPF before-after pressure difference in practical operation of the diesel vehicle can be realized through the terminal. According to the terminal, the emission of pollutants of the diesel vehicle can be supervised withhigher efficiency, position information of the vehicle is observed in real time through GPS positioning, and an active promotion effect is achieved for monitoring and technical improvement of the fields of automobiles and traffic.

Description

technical field [0001] The invention relates to a vehicle-mounted remote monitoring terminal based on various sensors, in particular, it belongs to the development technology of a diesel vehicle remote terminal. Background technique [0002] With the development of urban traffic and the substantial increase in the number of motor vehicles, motor vehicle emissions have become the main source of environmental pollution. Automobiles are the main contributors to the total amount of motor vehicle pollution emissions, with nitrogen oxides NOx and particulate matter PM exceeding 90%. Classified by fuel, the NOx emitted by diesel vehicles in the country is close to about 70% of the total vehicle emissions, and the PM exceeds 90%. Both NOx and PM are extremely harmful to the environment and human body. After NOx enters the alveoli, it can form nitrous acid and nitric acid, which will have a severe stimulating effect on lung tissue. NOx and HC react chemically after being irradiate...
