Supercharger rotating speed monitoring and recording and fault early warning device and early warning method

Abstract

The invention belongs to the field of supercharger monitoring and controlling, and particularly relates to a supercharger rotating speed monitoring and recording and early warning device and an earlywaning method. The supercharger rotating speed monitoring and recording and early warning device comprises a single chip microcomputer, a rotating speed measuring circuit, a clock module, a rotating speed output module, an early warning module, a power module and a memory module, wherein the rotating speed measuring circuit, the clock module, the rotating speed output module, the early warning module, the power module and the memory module are connected with the single chip microcomputer. The rotating speed measuring circuit and the clock module are connected with the input end of the single chip microcomputer. A rotating speed recording module, the rotating speed output module and the early warning module are connected with the output end of the single chip microcomputer. In addition, depend on a rotating speed recording function, a service life early warning function is applied to supercharger monitoring and controlling for the first time, current maintenance of a supercharger is facilitated, and using safety and reliability of the supercharger are improved.

Description

technical field [0001] The invention belongs to the field of supercharger measurement and control, and in particular relates to a supercharger rotational speed monitoring record and early warning device and early warning method. Background technique [0002] The main function of the supercharger is to increase the air intake of the engine, so as to achieve the purpose of increasing power, improving economy, and improving emissions. In recent years, the use of superchargers has been continuously upgraded with the increasing demand for engine power in OEMs. At the same time, the upgrade of emission standards has also led to a substantial increase in the market share of superchargers. Whether the performance of the supercharger is stable or not directly affects the smooth operation of the engine, so the supercharger has become an important part of the complete engine. At present, the domestic supercharger speed test device only has the function of monitoring the real-time speed...

AI Technical Summary

Problems solved by technology

The performance stability of the supercharger directly affects the smooth operation of the engine, so the supercharger has become an important part of the complete engine. At present, the domestic supercharger speed test device only has the function of monitoring the real-time speed of the supercharger. If the room wants to record the speed data, it can be completed after the speed output of the tachometer is installed and the acquisition card is connected to the host computer. After leaving the factory, the speed data cannot be recorded.

Especially when the supercharger fails, in many cases, the cause of the supercharger's failure cannot be traced, and the failure to accurately locate the cause of the failure is a shortcoming for engine OEMs and supercharger manufacturers.

The fault warning for the supercharger is even blank at present, and most OEMs can only do the overspeed warning
