At present, the shortage of energy is becoming a significant reason to restricteconomic development of one country. To reduce the oil demand and environmentprotection, the ways to getting improve efficiency of Photovoltaic solar using shouldbe considered by countries and regions all around the world. Which is an integral partshould be contained by any new energy policy. Some great achievements in using ofPhotovoltaic solar in China have being made, but there are still some problems being,especially in the development of remote collection of Photovoltaic solarenvironmental parameters. The lack of Environmental data for researchers to researchthe development of Photovoltaic solar efficiency is seriously restricting thedevelopment of Photovoltaic solar development and application. Therefore, there is arequirement for one data enquiry system which can get the solution to existingproblems, to improve the accuracy and timeliness of data transmission of Photovoltaicsolar, environment, and to facilitate the data analyzing of the researchers.Photovoltaic solar and environmental data acquisition system and data networkmonitoring platform used RS-485 industrial communication technology andembedded technology-based to solve the remote data collection and queries. ThisThesis embedded systems chose as the core, and analyzed the key technologies ofhow to structure the system. The scene of temperature, humidity, solar irradiance, andwind direction data will be collected and transmitted by the RS-485 communication todata management platform, storage, and network transmission via the Internet toanyone who wants to query, analyze the data. Get the promotion to enhance thePhotovoltaic solar efficiency development and the project site selection decision. Itcan solve the problem of remote data acquisition and transmission, has a greaterimpact to improve the efficiency of Photovoltaic solar using.This thesis analyzed the demand of environment parameters on photovoltaicpower generation, provided the overall system design of the program, hardware andsoftware programs and data network monitoring platform construction. The thesis wasconstructed based on ARM &μc/OSⅡembedded platform, and achievedenvironmental parameters data collection on this basis. The system hardware used theARM CORTEX-M0 microprocessor contained LPC1114 as the core, and RS-485remote communication. In addition, the system used the ORACLE database to storethe data, and using the JAVA programming language to develop the B/S structure of the data network monitoring platform.The innovation of the paper is using the real-time function ofμc/OSII embeddedoperating system to solve the problems of parallel processing of multiple tasks in thesystem, to protect the stability of the system, reliability, and improved the speed ofsystem. And more, the network monitoring platform is highly scalable, with a varietyof data interfaces, can be easily accessed by other data system. The system can beused in the mining industry, agriculture, meteorology and other fields with some smallmodifications.
