The Development Of The High-speed Temperature-measuring Instruments Based On The TMS320LF2407

This dissert aims at developing the high-speed temperature-measuring instrument for the application of high energy density heating. The instrument developed has the ability to fast measure a temperature that can be displayed or printed after being processed by the FFT algorithm.In Section I, this dissert firstly gives the introduction of the temperature- measuring instruments, and demonstrates the necessity and practicability of the development of the high-speed temperature measuring instruments based on the high technology of the DSP chip capable of processing data at high speed by the wide survey of the civil markets. Then on the basis of the introduction of the development and the features of the DSP chip, this paper discusses how to select the DSP type in my developed system. As a result, based on the good configuration and characters of the TMS320LF2407 DSP chip, it is selected as the DSP chip of our developed high-speed temperature-measuring instrument for fast processing the temperature data. In Section II, the functions of my developed instrument are explained in detail. Based on them, we optimally design all hard wares in my developed instrument system by their delicate selections. Accordingly, We design the software system for the hardware system using CCS2.0 (code composer studio version 2.0). Finally, in particular, this dissert explains the key techniques of our developed instrument system such as the designs for resistant interference and for printing circuit board.After the hardware and the software of it are carefully debugged and tested many times, my developed high-speed temperature-measuring instrument based on the DSP chip technology meets the request of measuring temperatures at a high speed and works well.
