Abstract

The invention discloses a phase sensitive detecting type oil consumption tester based on temperature detection, and is characterized in that the phase sensitive detecting type oil consumption tester comprises a single chip microcomputer, a voltage-stabilized power supply module, a display, a keyboard, a wireless transmission unit, a network interface, a phase sensitive detecting unit, a temperature detecting unit, and an oil consumption sensor. The voltage-stabilized power supply module, the display, the keyboard, the wireless transmission unit, the network interface, the phase sensitive detecting unit, and the temperature detecting unit are all connected to the single chip microcomputer, and the oil consumption sensor is connected to the phase sensitive detecting unit. The phase sensitive detecting type oil consumption tester has the phase sensitive detecting unit which can judge oil consumption signals and inhibit other interference signals. The influence of the interference signals on the phase sensitive detecting type oil consumption tester based on the temperature detection is eliminated, and the detection accuracy of the phase sensitive detecting type oil consumption tester based on the temperature detection is improved. The phase sensitive detecting type oil consumption tester based on the temperature detection can detect the machine oil temperature and prevent the machine oil temperature from becoming over high so as to damage the oil consumption tester.

Description

technical field [0001] The invention relates to a fuel consumption tester, in particular to a phase-sensitive detection-type fuel consumption tester based on temperature detection. Background technique [0002] The fuel consumption meter is an important testing instrument to measure the economic performance and dynamic performance of motor vehicles, and it is a necessary testing instrument for the automobile and tractor manufacturing industries, agricultural machinery supervision departments and scientific research departments. The currently used fuel consumption tester must be connected to a computer with a data cable to complete the transmission of test data and test curves. And the tester is frequently connected with the computer, which greatly affects the work efficiency of the tester. At the same time, the traditional fuel consumption tester is easily affected by external interference signals during work, resulting in low detection accuracy and unable to meet people's ...
