[Abstract]:With the deepening of industrialization, mankind's energy dependence is more and more strong. But the traditional fossil fuel reserves are limited, will eventually be depleted, the development of new energy imminent. Solar energy has a wide distribution, large amount, environmental protection and other advantages, in the field of new energy has been widely concerned. Solar tracking technology can effectively improve the efficiency of solar power generation system, which has great significance. This paper analyzes the existing tracking features, especially introduces the bionic technology. The sunflower technology has the advantages of easy modularization, adjustable precision, low energy consumption. This paper is based on the technology, developed the simulation system, test.1, first introduced the tracking principle of bionic tracking technology of sunflower street lighting, the application background was optimized based on the simplified, parallel two axis tracking model. After analyzing the operation rules of the sun, Sunshine model, established the target tracking system, tracking accuracy and so on. The key parameters in the tracking range and tracking accuracy as constraint driven geometry relation analysis and structure should be simplified parallel two axis force tracking system is analyzed by finite element method, the displacement ratio, the reliability verification of.2 tracking system, system design for tracking mechanism, the design of control circuit of two parts. The tracking mechanism design of modular design, completed the design and action unit sensing unit; modular sensing unit will be placed in a two axis sensor, simplifies installation and production; modular action unit adopts gear rack and limit switch the way to ensure the reliability of the mechanism. The control part of the design is divided into the design of hardware circuit design and software program; the hardware part, with MSP430F149 as the main control chip The circuit includes a microcontroller circuit, microcomputer system, signal acquisition module, motor control module and JTAG; to achieve the day tracking software program, the function of sleep at night, to complete the data acquisition, state determination, night sleep, tracking the four parts of the writing and debugging of the.3 test, indoor test and field consists of two parts the test finished. The indoor test track life, tracking accuracy and tracking speed test. Field test for tracking performance test and power generation efficiency of the two part of the test; tracking performance testing was completed to test and analysis of error tracking system work; power performance test of photovoltaic system by comparing the belt tracking mechanism and fixed photovoltaic system upgrade the power generation performance, the charging power, power generation, to improve test and analysis of the percentage of power generation.
