Photovoltaic tracking support group control system and method based on wireless communication

Abstract

The invention provides a photovoltaic tracking support group control system based on wireless communication, and the system comprises an upper computer, a main control unit, and a plurality of photovoltaic tracking support drive subunits. The main control unit comprises a first single-chip microcomputer, a first manual / automatic change-over switch, a first wireless communication module, a first hand-operated module, a wind speed sensor, and a clock module. Each photovoltaic tracking support drive subunit comprises a second single-chip microcomputer, a second manual / automatic change-over switch, a second wireless communication module, a second hand-operated module, an inclination angle sensor, and a motor drive module. The upper computer is in bidirectional connection with the first single-chip microcomputers, and the first wireless communication modules are in wireless communication connection with the second wireless communication modules. The system achieves a purpose that one main control unit achieves the wireless control of a plurality of tracking supports through the wireless mesh network technology based on Zigbee, carries out the angle tracking control of a photovoltaic tracking support group, reduces the cost, and also greatly reduces the installation and debugging cost.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic solar energy, and in particular relates to a control system and a control method for a photovoltaic tracking bracket group based on wireless communication. Background technique [0002] Today, when global resources are increasingly scarce, the use of solar energy is favored by people. Solar energy is a low-density, intermittent, and spatially changing energy source, which requires high collection and utilization. The efficiency of the solar receiving module is not fully exerted due to the cosine effect caused by the oblique sunlight. Installing a device for tracking the sun on the solar receiving module, so that the sun's rays irradiate the solar receiving module vertically is the solution to the low power generation efficiency caused by the cosine effect. Effective way. [0003] Compared with the photovoltaic fixed bracket, the solar tracking bracket can make the placement angle of the pho...
