Develop The Environmental Monitoring And Communication System Of Solar Energy Management System

As China has strongly advocated to create environmental conservation-oriented society, the Solar photovoltaic power generation system become the key of the State investment. The Solar Energy Management System is the important component of the Solar photovoltaic power generation system can accomplish Collecting and Monitoring of the system parameter and control the whole Solar photovoltaic power generation system. Meanwhile, the technique of Environmental Monitoring Technology is an important role of the whole system which is a part of The Solar Energy Management System's research. Based on the domestic and international advanced technique of Environmental Monitoring Technology, it proposed and implemented an environmental monitoring system. The system can realize real-time and automatic collect the Weather environment monitoring data of vertical profiler. In the acquisition and monitoring system, the control system is the core element.This paper's main task is the design and the implementation of the Environmental Monitoring and Control System which is the Solar Energy Management System's Subsystem. The overall design of electronic and communication system, Environmental monitoring equipment hardware design, set up ARM-Linux operating systems, software design and system commissioning are given.Environmental Monitoring of Electronic and Communication System is the subsystem of the Solar Energy Management System. This monitoring system can be divided into two parts: Monitoring data acquisition subsystem and Environmental Monitoring of Electronic and Communication subsystem. Environmental monitoring platform obtain weather environmental data through numbers of Measurement sensor (Temperature, humidity, light intensity, wind etc. And then the data save to a large capacity SD card and USB device. Environmental Monitoring of Electronic and Communication System obtain the collected data through the serial port (RS232). Utilizing A/D sampling read battery voltage and get the buoy stance information by Angle sensor. The data got stored and will send to monitoring center by ZigBee at the scheduled time. The monitoring system works once for 24 hours. Communication platform using the solar battery and storage battery as power that can improve reliability of the system.Environmental Monitoring and Control System uses AT91SAM9260 as core chip which has abundant port resources, in order to satisfy various profiler of the data collection, storage and communication needs. The AT91SAM9260 is based on the integration of an ARM926EJ-S processor which has one 4-channel 10-bit Analog-to-Digital Converter, one SSC, four USART and two 2-wire UARTs.The chip has many serials that can reduce the system's power. The chip uses Linux as operating system.The software design uses the modular design method, and divides into serial data acquisition module, reading and writing files module, motion control module, ZigBee communication module, the monitoring platform software is programmed in VB language. Experiments show that the functions of control subsystem perfectly, operate stably of the Environmental Monitoring of Electronic and Communication system. Weather environmental data acquisition can transmitted to monitor center accurately that meet the design requirements.
