Electric vehicle smart instrument control system

Abstract

The invention relates to the technical field of instruments, in particular to an electric vehicle smart instrument control system. The electric vehicle smart instrument control system comprises a single-chip microcomputer core module, a sensor module, a PC (personal computer) and a display module. The sensor module collects information and transmits the information to the single-chip microcomputer core module through an input module. The converting module, connected through a parallel peripheral interface, of the PC mutually exchanges processing data with the single-chip microcomputer core module. The display module is connected with the single-chip microcomputer core module through a serial periphery interface. The electric vehicle smart instrument control system has the advantages that the MC68HC90 single-chip microcomputer is used as the control core, the display function of traditional instruments is kept by the aid of LCD dynamic display, the single-chip microcomputer secondarily processes the collected data in real time so as to obtain vehicle operation parameters which cannot be directly collected by a sensor, and the vehicle operation parameters can also be dynamically displayed on an instrument panel through LCD; the system further comprises an interface for communicating with the PC, and the collected vehicle operation parameters can be recorded, stored and analyzed in the PC.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to an electric vehicle intelligent instrument control system. Background technique [0002] Electric vehicles include pure electric vehicles (EV), hybrid electric vehicles (HEV) and fuel cell vehicles (FCV), which are ideal zero-emission or low-emission vehicles. The operating parameters of electric vehicles are very different from those of traditional internal combustion engine vehicles, and it is necessary to increase the real-time detection of motor and battery performance parameters. The traditional instrument system only has the function of displaying the detection parameters, and cannot automatically record, store, and analyze; the experimenter can only record the data displayed by the instrument at regular intervals, not only the workload is relatively large, the objectivity of the data is not strong, and the later The data processing work is cumbersome, and t...

Problems solved by technology

[0003] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide an electric vehicle intelligent instrument control system, which is used to solve the problem that the traditional instrument system in the prior art only has the function of displaying the detection parameters and cannot perform automatic recording. Storage and analysis; the experimenter can only record the data displayed by the instrument regularly, not only the workload is relatively large, the objectivity of the data is not strong, but also the later data processing work is cumbersome, and the preservation of the original data is difficult
