Design Of An Embedded Monitoring System For Solar Power Station

This paper describes the technology of solar-powered supply and its research status of solar power station monitoring system. According to the system requirements,designed the monitoring system used for solar power station.According to the function of the monitoring system, briefly discussed the structure of solar power station monitoring system, design solutions is determined, the design of the whole system is in accordance with the solutions.Based on the needs of actual system solutions, we selected the freescale S12 X series microcomputer as the slave controller, selected st-microelectronics’ s 32-bit embedded micro-controller STM32F103 as the host, and briefly discussed the hardware design.In this paper, the main content is about the programming, as embed the real-time operating system μC/OS-Ⅱinto the slave controller, we also discussed how to embed real-time operating system μC/OS-Ⅱ into the micro-controller.Porting μC/OS-Ⅱ operating system into the micro-controller is mainly include the editing header files, asm files and C file. Based on the porting completed, we discussed the structure of the task module part of the coding of task.In the user program section, we discussed slove program, host program and monitor programs on the PC side. The slova program includes A/D converter driver,Zig Bee protocol dispatcher program, EEPROM read/write procedures, temperature and humidity reading program and so on, the host program in mainly about GPRS module program; and Monitor computer program on PC side can monitor and control the solar power station through different windowThis system has been applied in the laboratory environmental for testing, and has accomplished moist of the goal.
