The Design Of Energy Collector System Based On AT91RM9200

With the rapid development of the society, traditional way of electric energy acquisition exists problems of ineffective and finite transmission distance, therefore, build more effective and convenient system is needed. Nowadays, the technology of ARM trends to be mature, the embedded system has been becoming the highlight in the computer technology, it has made a wide range of applications. Because of these characteristics, the designer of such equipment will be provided to a very good technical support.The purpose of this paper is to develop a microprocessor-based embedded AT91RM9200 andμC/OS-II operating system, which is a common platform for embedded development, to provide a more complete hardware and software environment for embedded design. Using Atmel's AT91RM9200 ARM embedded processor core for embedded systems hardware system design, including memory modules, serial interface module, reset the module, and clock circuitry, JTAG debug module, network interface module, power module design. In considering the case of electromagnetic compatibility, and then use software Protel DXP 2004 schematic drawing hardware, and according to the schematic for a PCB design to complete the entire board of the hardware structure of the physical structures in the software design process, a bootloader in accordance with AT91RM9200 embedded system is designed, by using the software ADS1.2,we can accomplish system clock and the interrupt of handling vector, so we can accomplish the transplant of theμC/OS-Ⅱoperating system from AT91RM9200.Finally, we finish the design of the embedded energy collector. And, test the functions of energy acquisition.Energy collector as access to electric meter conversion device energy management system.And because it is responsible for collecting electrical energy, so there is no efficiency issues. If by increasing its fiber-optic chip, equipped with optical interfaces, enabling long-distance transmission of electric energy, electric energy to facilitate the monitoring and management.
