The Study Of Platform For Condition Monitoring And Analysis Based On DSP

Many key equipments of industrial fields have demands of status monitoring and signal analysis. Therefore kinds of instruments are developed. With the development of electronic industry, more and more people are focusing on instruments for status monitoring and signal analysis based on different hardware and software framework.The development of instruments for status monitoring and signal analysis at home and that of at overseas is firstly compared. A multi- function status monitor, signal analyzer, based on DSP-TMS320F2812 and Complex Programmed Logic Devices (CPLD), is discussed. Large-scale SRAM chips are used to avoid of losing real-time data. Powerful CAN bus controller, eCAN, is used to transmit data, which is integrated in the DSP. CAN bus has lots of advantages over the RS-485 bus. How the hardware system is constructed, how the ADC is used and how the software development environment is built, all of these will be demonstrated through a FFT example of a extern signal. The possibility and necessity of porting embedded real-time operation system,μC/OS-Ⅱ, to DSP platform is introduced. This platform can improve reliability and real-time performance of software. And special software is used to obtain the capability of multi-channel data acquisition, storage, analysis and communication without changing hardware design.In the end,a expert axletree system is discussed. The test do well as it is expected.
