The Design Of Electircal Dynamometer PC Monitoring Software

In recent years, with the progress of science and technology as well as the energycrisis, people showed a trend of growth in the demand for electric cars, also putsforward higher requirements on motor testing technology. rapidly developing andreliable ac electrical dynamometer is main equipment of electric dynamometer system.In order to meet the demand of laboratory dynamometer system of monitoring, Thedesign of automating PC monitoring software is extremely important. This topic isadvanced under this background.Firstly, based on the electric dynamometer system, I analyze the mainhardware electric dynamometer test bench principle and advantages, build the modelof the measurement and control system. Secondly, design the control systemcommunication network, realize the perfect cohesion from the CAN bus to the TCP/IPnetwork until the personal computer. The communication network is a suitablenetwork model of the measure and control system in the laboratory.Finally, on the basis of computer measurement and control system, accordingto the demand of the laboratory measurement and control research and development, Iput forward the electrical dynamometer PC monitoring software module design. Thesoftware is programmed based on the general high-level language Visual C++MFC(Microsoft Foundation Classes) and NI controller, mainly including parameter setting,data acquisition and display, report generation, fault warning etc. Function module.Among them, the curve of data fits by manipulating the Measurement Studiocontroller of NI Company, finally shows on the upper machine; The data storage usesthe database technology, Which is a easily data management and call model. Thestatements generated using Word operation, for the researchers further comparisonand reference. The electric dynamometer PC monitoring software realizes the dualfunction of measurement and control system monitoring and archiving, at the sametime, avoids to use expensive professional software, also save lab experimentoverhead, It is very important for electric.
