Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the output voltage of the photovoltaic panel 1 is converted into the voltage range allowed by the analog-to-digital conversion unit 3 through the level conversion unit 2, and the analog-to-digital conversion unit 3 converts it into a digital value and sends it to the MCU control unit 4, and the MCU control unit 4 After processing and analyzing it, a control signal is output. The control signal is amplified by the control signal output unit 5 and sent to the stepper motor drive unit 6. The drive unit 6 drives the stepper motor 7 to rotate, and the stepper motor 7 drives the photovoltaic panel 1 to turn to the direction of the sun. .

[0016] The photovoltaic panel 1 charges the battery 9 through the battery charging control unit 8. When the voltage of the battery 9 exceeds its maximum allowable value, the charging control unit 8 cuts i...

Abstract

The invention discloses a sensorless single-shaft sun tracking system which consists of a photovoltaic panel, a level conversion unit, an analog-to-digital conversion unit, an MCU (Micro Controller Unit), a control signal output unit, a stepping motor drive unit, a stepping motor, a storage battery charging control unit and a storage battery. The photovoltaic panel in the system serves as a power generating device and a light sensor to assist the MCU in judging a sun direction; compared with the light sensor in the existing sun tracking system, the sun direction can be reflected better, the influence of a mounting azimuth on the tracking accuracy when the sensor is mounted is removed, a mounting and debugging process of the sun tracking system is simplified greatly, and the mounting cost is lowered. The storage battery charging control unit in the system has a function of protecting the storage battery and a function of automatically turning off the system after sunset, automatically turning on the system after sunrise and not turning on the system in cloudy days or insufficient light, and the purpose of reducing consumption of the system is achieved.

Description

technical field [0001] The invention relates to the field of solar systems, in particular to a sensorless solar system based on a single-chip microcomputer and suitable for photovoltaic panels. Background technique [0002] At present, the tracking methods of existing tracking devices at home and abroad can be divided into two types: single-axis tracking and dual-axis tracking. Whether it is single-axis tracking or dual-axis tracking, sun tracking devices can be divided into: clock type, program control type , differential pressure, controlled release, photoelectric and sun tracking devices for astronomical observation and weather stations. Although the devices used to observe solar activity are accurate in tracking, they are expensive; the principle and structure of differential pressure and controlled release sun trackers are relatively complicated; clock-type and program-controlled tracking devices have cumulative errors and cannot be automatically eliminated; photoelectr...
