Embodiment

[0019] Such as figure 1 As shown, the simple fuel consumption tester based on temperature detection and signal filtering processing of the present invention consists of a single-chip microcomputer, a signal filtering unit connected to the single-chip microcomputer, a stabilized power supply module, a display, a keyboard, a wireless transmission unit, a temperature detection unit and a network. interface, and a fuel consumption sensor connected to the signal filter unit.

[0020] Among them, the fuel consumption sensor is set in the fuel tank of the engine to collect the fuel consumption information of the engine and transmit it to the signal filter unit. The DYP / DS1309 fuel consumption sensor produced by Shenzhen Dianyingpu Technology Co., Ltd. is preferred. This type of fuel consumption sensor has The temperature compensation range of -40 ~ 80 ℃ can be used in various states of the engine, and has high sensitivity.

[0021] As the control center of the present invention, the...

Abstract

The invention discloses a simple oil consumption tester based on temperature detecting and signal filtering. The simple oil consumption tester is characterized by being composed of a single-chip microcomputer, a voltage-stabilized power supply module, a display, a key board, a wireless transmission unit, a signal filtering unit, a network interface, a temperature detecting unit and an oil consumption sensor connected with signal filtering unit, wherein the voltage-stabilized power supply module, the display, the key board, the wireless transmission unit, the signal filtering unit, the network interface and the temperature detecting unit are connected with the single-chip microcomputer. According to the simple oil consumption tester, external interference signals can be removed through the signal filtering unit, and therefore the influence brought by the interference signals on the detecting precision of the tester are avoided; the machine oil temperature can be detected, and therefore the oil consumption tester can be prevented from being damaged due to the fact that the machine oil temperature is too high.

Description

technical field [0001] The invention relates to a fuel consumption tester, in particular to a simple fuel consumption tester based on temperature detection and signal filtering processing. 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 p...
