System for measuring and monitoring fuel consumption of automobile in use in real time and measurement and monitoring method thereof

Abstract

The invention discloses a system for measuring and monitoring the fuel consumption of an automobile in use in real time and a measurement and monitoring method thereof. The system comprises on-board equipment, roadside equipment and a monitoring center, wherein the on-board equipment is arranged in the automobile, is connected with an on-board self-diagnosis system by an on-board diagnosis (OBD) interface module to read fuel consumption information and automobile information, and calculates the total fuel consumption of an engine by a master control unit; and the roadside equipment reads the total fuel consumption of the automobile by wireless communication and transmits super-standard automobile information to the monitoring center. In the method, the total fuel consumption is calculated by the fuel consumption information read from the on-board self-diagnosis system and a fuel charge calculation formula; and the roadside equipment reads the fuel consumption of the automobile and the super-standard automobile information to the monitoring center for processing by the wireless communication, and simultaneously informs a driver of the automobile with the super-standard fuel consumption. In the system and the method, data is read from the on-board self-diagnosis system, so the technology is simple and reliable and the detection accuracy is high; and the system and the method are applied to the fuel consumption detection of the automobile in any state to integrate the fuel consumption detection, maintenance and management of the automobile.

Description

technical field [0001] The present invention is a real-time measurement and monitoring system of fuel consumption of in-use vehicles and a measurement and monitoring method thereof based on vehicle-road coordination technology, relates to the field of vehicle detection and the field of modern traffic technology, and can be widely used in the detection, supervision and management of fuel consumption of in-use vehicles. Background technique [0002] The sharp increase in automobile consumption and fuel consumption has brought enormous energy and environmental pressure to our country. The proportion of road transportation gasoline and diesel consumption in my country's petroleum energy consumption has been increasing year by year; in terms of energy consumption per unit of transportation, the fuel consumption per 100 ton-kilometers of my country's operating vehicles has generally shown a steady and slightly rising trend, that is, gasoline buses and diesel buses have respectively...

AI Technical Summary

Problems solved by technology

[0004] In my country, the detection of in-use vehicles is carried out on the inspection line in the form of annual inspection. Since the detection of fuel consumption of in-use vehicles needs to disassemble the oil inlet and return pipes of the engine and connect them to the fuel consumption meter for measurement, the preparation time is long (approx. 1 hour), sometimes it is necessary to destroy the original structure of the car, which cannot adapt to the fast pace of the inspection line. At present, the annual inspection of automobiles stipulated by the state cannot be carried out in most parts of the country for fuel consumption, and the fuel consumption of in-use vehicles is even more important. is out of control
