Photovoltaic array positioning tracking monitoring system based on internet of things and operating method

Abstract

The invention discloses a photovoltaic array positioning tracking monitoring system based on the internet of things and an operating method. The photovoltaic array positioning tracking monitoring system based on the internet of things is characterized in that a plurality of wireless measurement and control instruments are respectively used for collecting photovoltaic array data with 1-N numbered subdomains, respectively perform data interaction with the adjacent wireless measurement and control instruments by short distance wireless communication links, and then send interactive data to a wireless gateway, wherein the data comprise autonomous positioning data of the photovoltaic array; the data are uploaded to a wireless transceiver by intermediate distance wireless communication links and then are transmitted to a local master control center; the local master control center sends the data to a different master control center in a long-distance mode by an Internet network or a satellite communication system; and the data are subjected to verification and analysis and the wireless measurement and control instruments are subjected to remote control in accordance with the analysis result. The method of the wireless measurement and control instruments on the autonomous positioning of the photovoltaic array comprises a transmitting radius determination method, an initial positioning algorithm, a boundary problem processing method and a Y value conflict processing method. Accurate positioning of photovoltaic modules can be realized without expanding positioning devices, thus reducing the installation complexity and the error rate and strengthening the system robustness.
