Development And Research Of Multi-thread Real-time Engine Combustion Analysis System Under The NT System

In analyzes and refers to the development research results of the domestic and foreign internal combustion engines combustion analysis system , and the synthesis contrasts the fit and unfit quality of each system, this paper embarks from the reality develops exploitation a set of test system which functions practical, operation simple, the price is cheap, and promotion expansion ability strong. This set of system was compiled independent under the mature software and hardware platform, through transfered the DLL to realize the visit and operation with the first floor hardware. Only needs to install this test analysis system on the ordinary computer system, and matches the corresponding data acquisition meter, it may realize the function. The promotion or the function expansion be come to realize only needs in the original system to join the corresponding function modules , does not need carries on the modification to the hardware and DLL. Therefore this system has thereinafter advantages that disposition and the promotion is agility, the hardware system invests slightly, the entire wrap system cost may control.This paper introduced the development and the research situation of multi-thread real-time engine combustion analysis system under the NT system. The exploitation and running of the entire wrap system all is under the windowsNT environment. With the aid of windowsNT formidable API function-storehouse, the good stability and the versatility, this paper utilize the C + + language and the translation environment of Visual C+ + to develop a set of multi-thread and the real-time internal combustion engine data acquisition analysis systems. This set of system can gather the explosion pressure in the cylinder, the engine corner signal of the multichannel signal, and carries on the gathering signal to recuperate, compute, analyze, store and plot and so on, finally obtains the understanding data and the picture which can direct-viewing know by the person, furthermore enables each user to the engine which tests to have the concrete understanding, and has a basic understanding according to the data of each kind of test which the system provides to measure in the engine work process and the air cylinder combustion condition. This series of tests analysis is advantageous to the instruction function to optimize the engine combustion organization and the structure.
