Abstract

The invention provides an integrated measurement system for indirectly measuring the oil consumption of vehicular fuel oil and aims at providing the integrated measurement system with the advantages of capabilities of continuously detecting and displaying remaining oil mass, a real-time oil consumption valve, total oil consumption and hundred-kilometer oil consumption rate of the vehicle and accuracy and reliability in measurement. The integrated measurement system disclosed by the invention is realized by the following technical scheme that an exciting source circuit of a signal conversion assembly (2) is used for preprocessing a current oil mass data signal acquired by a signal receiving assembly (3) through a computing center (4) and an oil mass sensor assembly (1) and then converting the received capacitance signal into a standard voltage signal or a current valve signal; the standard voltage signal or the current valve signal enters the computing center (4) through an input/output interface (5) and is sampled by an A/D (Analogue/Digital) converter in the computing center (4); meanwhile, an ECU (Electronic Control Unit) oil injection pulse signal is directly transmitted to a single chip microcomputer in the computing center; and the processed data are outputted to a display unit or uploaded to an upper computer by resolving program software.

Description

technical field [0001] The invention relates to a comprehensive measurement system mainly used for measuring the remaining liquids such as gasoline, diesel oil and alcohol in the vehicle fuel tank and the real-time fuel consumption of the vehicle. Background technique [0002] Generally, the function of measuring and displaying the remaining fuel quantity of vehicles is very simple, and generally it is an analog pointer instrument that can only roughly display the fuel quantity. Such as Image 6 The traditional vehicle remaining oil measurement system shown mostly adopts contact measurement. The measurement systems used in the prior art mainly include float variable resistance sensors and magnetic induction sensors. And most of the measurement of the oil quantity in the vehicle fuel tank still adopts the traditional float variable resistance sensor method. For example, the float variable resistance liquid level sensor used in the Toyota Crown sedan has a float connected to...
