Real-time fuel consumption remote monitoring equipment based on mobile Internet

Abstract

The invention discloses a real-time fuel consumption remote monitoring device based on the mobile Internet, which is characterized in that it includes a fuel consumption detection device, a vehicle-mounted mobile terminal and an information management center, and the fuel consumption detection device periodically transmits the detected fuel consumption information to The vehicle-mounted mobile terminal, the vehicle-mounted mobile terminal calculates the actual fuel consumption from the received fuel consumption information, and detects the driving information in real time at the same time, and periodically passes the actual fuel consumption and the driving information GPRS The wireless communication network transmits to the information management center, and the information management center receives the information transmitted from the vehicle-mounted mobile terminal for tracking and processing, and monitors the fuel consumption and driving trajectory of the vehicle in real time, which can fundamentally solve the problem of stealing and selling oil, falsely reporting expenses, public car private Use, vehicle whereabouts are unknown and other issues.

Description

technical field [0001] The invention relates to a real-time fuel consumption remote monitoring device based on the mobile Internet. Background technique [0002] Fuel costs are the bulk of motor vehicle operating costs. Reducing fuel and improving vehicle efficiency are important issues that need to be resolved urgently in vehicle supervision. There are many oil quantity monitoring methods currently on the market, but all have various defects: [0003] (1) The oil quantity monitoring method based on pressure induction, install a pressure sensor at the bottom of the fuel tank, measure and calculate the height value of the oil level of the fuel tank through the output pressure value and fuel density, and then calibrate the oil quantity value in the fuel tank according to the height of the oil level . This method has the following defects: (a) In this method, the pressure sensor is installed at the bottom of the fuel tank, leading to the atmosphere and the pressure guide port...

AI Technical Summary

Problems solved by technology

This method has the following defects: (a) In this method, the pressure sensor is installed at the bottom of the fuel tank, leading to the atmosphere and the pressure guide port in the fuel tank, which is often blocked due to the influence of oil pollution, so after working for a period of time, it cannot measure normally ; (b) Since the height of the fuel tank is generally less than 1 meter, the range of the selected pressure sensor is generally about 0 to 10KPA, and the measurement accuracy of this type of micro-pressure sensor is low; (c) The pressure sensor is installed at the oil drain valve at the bottom of the fuel tank , cannot be disassembled frequently, which will affect the cleaning of the fuel tank; (d) The pressure sensor is greatly affected by the temperature, and the measurement results are not necessarily accurate

This method also has some problems: (a) the fuel tank needs to be relatively large modified, the construction is difficult, and there are certain safety hazards; (b) the vibration will cause the oil level to change greatly during the driving process of the vehicle, and the accuracy is not high

The principle of this method is simple, but the feasibility is poor: (a) It is necessary to manually calibrate the numerical relationship between the fuel volume and the voltage value, and the calculation formulas of different models or fuel tank models are also different, so it is difficult to implement; (b) this The method requires a certain degree of modification to the fuel tank, and there are some potential safety hazards

[0006] At present, there are various problems in the use of vehicles: (a) the driver cannot control the stealing and selling of oil; Low efficiency; (c) vehicle costs remain high, and various costs do not match the reality (such as falsely reporting tolls, fuel costs, etc.); (d) lack of supervision on vehicle use (such as frequent private use of public vehicles, private work, etc.); ( e) Bad driving habits or ways of drivers will cause serious fuel waste. According to statistics, different driving styles may lead to a difference of 20% or even 50% in fuel consumption levels

These problems will bring huge economic losses to enterprises and institutions
