Abstract
A multi-parameter monitoring system has been designed for mechanical and electric equipment based on DSP and CPLD. Designing methods for hardware and software are introduced in this paper. As in the system, powerful capability for numeric operation of DSP is used to deal with real-time data, while CPLD is held responsible for logic control. Therefore, by combining DSP and CPLD, malfunction can be observed and alarming signal can be provided in due time.
Highlights
In the industrial field, the implementation of real-time monitoring and displaying of important parameters regarding the equipment are very necessary
The structure diagram is showed in Fig. (1)
At the core of the module device is a DSP, whose primary task is to analyze and process the signal from forward-channel according to certain algorithms so as to form various effective data to meet the preset functions, and the processed results are forwarded to the backward channel
Summary
The implementation of real-time monitoring and displaying of important parameters (such as pressure, temperature, liquid level, speed, vibration, etc.) regarding the equipment are very necessary. It makes use of DSP-TMS320LF-2407A as a processor, uses CPLD to determine logic control and communicates with the host computer via USB interfaces. It can enable the staff to master the working conditions of the equipment in a timely manner and the predictive maintenance of the equipment can be realized beforehand. This can further enhance the economic efficiency of the enterprises
