Parabolic Trough Solar Chip Collector Tracking System Design Based On SCM

This paper discusses the design methodology uniaxial parabolic trough solar tracking system and make debugging. Composition and function of the automatic tracking control system to achieve a detailed analysis and research.Mechanical parts, parabolic trough solar tracking system by the microcontroller automatically track azimuth, elevation angle can be adjusted manually on a regular basis, through the analysis of experimental data, to ensure that the tracking accuracy, to verify the feasibility of this tracking ethod. In the electronic control, the design is completed with STC89C52 microcontroller as the core hardware circuit, which includes DS1302 clock circuit, LCD display circuit a power management circuit. Then, depending on the date of the trajectory algorithm, using open-loop stepper motor control trategies to KeiluVision4 software development platform, the preparation of the master control program, LCD program, clock program, motor drives and other program modules, and with the KeiluVision4 and SCM Proteus virtual laboratory simulation software to build and implementing software and hardware emulation FBI. Eventually, according to this design, fabrication and commissioning complete hysical model.Single-axis solar tracking system designed in this paper, the use of single-chip control system to automatically track the sun azimuth, elevation angle can be adjusted manually to make solar tracking to maintain a high tracking performance to overcome the shortcomings of the traditional low precision ingle-axis tracking system, At the same time compared to dual-drive two-way tracking system with low cost, easy maintenance, etc.the experiment proved that the system follows the economic, efficient and reliable anti-interference ability, easy operation and maintenance of design principles for the romotion of solar energy has an important the practical significance. The design considerations Northwest sunny summer simplify biaxial to uniaxial, reasonable compensation in the track elevation angle,reduce costs, complete precision tracking, single-axis tracking system described herein, the structure is simple, cost-effective, especially suitable for all kinds of small civilian use of solar energy equipment.
