Abstract

The invention discloses a universal automobile combination instrument function detection device and relates to a tester. The universal automobile combination instrument function detection device comprises a power module, an input detection module, a single-chip microcomputer module, a frequency pulse signal module, a resistor signal module, a switch signal module, a CAN communication port and a serial port, wherein the power module supplies power to the single-chip microcomputer module, the input detection module detects whether input data is correct and inputs detected input data to the single-chip microcomputer module, and the single-chip microcomputer module respectively outputs corresponding data signals; and the frequency pulse signal module, after receiving pulse signals outputted by the single-chip microcomputer module, outputs corresponding frequency signals to an instrument, the resistor signal module, after receiving resistor signals outputted by the single-chip microcomputer module, outputs corresponding resistor signals to the instrument, and the switch signal module outputs switch signals outputted by the single-chip microcomputer module to switches. The universal automobile combination instrument function detection device has the advantages of high versatility, lightness, convenience, low cost, high production efficiency and the like, thereby being applied to various occasions including production, examination, service after sale and the like of an automobile combination instrument.

Description

Technical field [0001] The invention relates to a tester, in particular to a general-purpose automobile combined instrument function test equipment. Background technique [0002] Automobile combination instrument is an important device used to display and record various driving information and engine operating conditions of the automobile. It is convenient for the driver to understand and grasp the operating conditions of the various system components of the automobile at any time, and is an important condition to ensure the safe driving of the automobile. The existing automobile combination meter function testing equipment has a single function, and generally can only test the specific parameters of a specific combination meter. Many combination meters of different models and functions require multiple corresponding combination meter testers to operate. Moreover, this kind of equipment does not have a good plan for the place of use, and it is inconvenient to use. Summary of the...
