Research On Streaming Current Detector And Controller Based On ARM Embedded System

The embedded system has been employed in a wide field because of its miniaturization,customized and high-reliability. With the rapid development of micro-electronic techmology,those measurement and control systems of traditional can't meet demands of user gradually,so it is urgent that the new generation of measurement and control system for the streaming current goes forward on the way of digitization,intelligentization and integration.The main task of the research subject is to develop a set of new type measurement and control system for the streaming current based on ARM microprocessor after absorbing present system.The research work include mainly as follows:1. The subject discussed the streaming current technique and streaming current sensor,analyzed the present constructure of SC measurement and control system and its deficiencies.At last,the research methods in ARM embedded system on SC measurement and control system are given. 2. According to the principle and requirement, the subject designed the scheme of SC measurement and control system based on 32-bit ARM microprocessor(LPC2210)3. The concept and composing of embedded system are depicted generally.The characteristic of embedded system is analyzed. According to the general scheme,the hardware and software development environment based on the MCU ARM LPC2210 is conctructed.4. Each hardware component and application software had been completed. FIR filter had been designed and used increment PID arithmetic.The capability of system is improved.In conclusion,the design of hardware and software,the application of embedded system are detailed roundly. The embedded system model of development and process and the mothods of testing were obtained.The constructure and functions of SC measurement and control system have been inproved and firmly base for intelligentized instrument designing development was set up.
