Abnormality diagnosis system of fuel consumption of coach

Abstract

The invention discloses an abnormality diagnosis system of fuel consumption of a coach. The system is composed of a vehicle state detection module including a pressure sensor, a tire pressure sensor and a data receiving module, a GPS navigation module arranged at a vehicle, a fuel consumption calculation module, a fuel amount recording module, and a fuel consumption diagnosis module. The GPS navigation module sets different road condition evaluation values based on different actual road conditions. The fuel consumption calculation module is in communication connection with the vehicle state detection module is used for obtaining a load w, a tire pressure p, and a vehicle engine wearing value a of the vehicle. The fuel amount recording module consists of a fuel amount detector, a processorcommunicatively connected to the fuel amount detector and a memory communicatively connected to the processor. The fuel consumption diagnosis module in communication connection with the fuel consumption calculation module and the fuel amount recording module is used for reading a total consumption value and an actual consumption value and making a comparison. Therefore, a problem that the illegalrefueling and fuel stealing behaviors of the driver can not be monitored during the long-distance transportation process is solved; and the diagnostic accuracy of the equipment is improved, the falsediagnosis probability is reduced, and the credibility is high.

Description

technical field [0001] The invention relates to the field of automobile fuel consumption. More specifically, the present invention relates to a system for diagnosing abnormal fuel consumption of coaches. Background technique [0002] With the development of road traffic, long-distance buses are becoming more and more popular in various towns. The business rights of some long-distance buses belong to individuals, often the drivers. Therefore, there is no waste or stealing of fuel during long-distance transportation. However, most of the long-distance buses belong to some passenger and freight companies, and some drivers will have some careful thoughts in the process of driving for the passenger and freight companies, or refuel indiscriminately, or secretly suck part of the fuel from the fuel tank during transportation, and convert it into It is impossible for these passenger and freight companies to monitor the running status of these vehicles in real time, especially the fu...

[0002] With the development of road traffic, long-distance buses are becoming more and more popular in various towns. The business rights of some long-distance buses belong to individuals, often the drivers. Therefore, there is no waste or stealing of fuel during long-distance transportation. However, most of the long-distance buses belong to some passenger and freight companies, and some drivers will have some careful thoughts in the process of driving for the passenger and freight companies, or refuel indiscriminately, or secretly suck part of the fuel from the fuel tank during transportation, and convert it into It is impossible for these passenger and freight companies to monitor the running status of these vehicles in real time, especially the fuel consumption status of the vehicles, so there is an urgent need for a diagnostic system that can check whether there is abnormal fuel consumption during long-distance bus transportation
