Abstract

A time-dependent sunlight tracker capable of setting latitude and longitude, mainly composed of a signal processing device and a sunlight receiver adjustment device, characterized in that: the signal processing device contains a time module, a GPS module and a CPU module, and the time module can Automatically update the year, month, day, time or (and) manually input the year, month, day, and time. The GPS module can automatically or (and) manually input the latitude and longitude. There is a database stored in the CPU module. This database records different longitudes and latitudes and different years, months, days, The solar radiation angle of the time, the CPU module can also receive the year, month and day of the time module, the time signal and the longitude and latitude signal of the GPS module, and then compare it with the stored database to find out the solar radiation angle, and output the electrical signal after calculation and processing to Sun receiver adjustment device.

Description

Sun tracker over time with configurable latitude and longitude

technical field

The invention relates to a sunlight tracker, in particular to a tracker which automatically tracks sunlight with time.

Background technique

At present, the sunlight tracking system mainly uses the photoelectric signal processing circuit to judge the sunlight irradiation angle, and the accuracy of such a system is generally relatively high. However, in reality, there is not much difference in the lighting effect between direct sunlight and small angle of oblique illumination, which will reduce the return on investment of the above-mentioned type of tracker. Moreover, when the above-mentioned type of equipment has too much sunlight intensity, its components may be damaged, and when the sunlight intensity is too low, it cannot capture sunlight, causing its work to fail, and cannot make full use of the weak sunlight.

Chinese patent 2012101644670 discloses a GPS-based two-degree-of-freedom sun tracking system, which uses the GPS receiver to output latitude, longitude and time information every ten minutes, and compares it with the previous results. The cost rises; and in general, the latitude and longitude of the sun tracker does not change, which makes the functions of the above-mentioned system redundant.

Contents of the invention

The present invention improves on the above-mentioned deficiencies, abandons the photoelectric signal processing circuit for judging the sunlight irradiation angle, determines the angle change of the sun through time on the basis of the sun's operating law, and corrects the above-mentioned angle with GPS data, thereby obtaining an approximate Accurate sun irradiation angle, and then drive the adjustment motor to adjust the direction of the sun receiver.

The technical solution adopted in the present invention is: mainly composed of two parts: a signal processing device and a sunlight receiver adjustment device, characterized in that: the signal processing device contains a time module, a GPS module and a CPU module, and the time module can automatically update the year and month Day, time or (and) manual input of year, month, day, time, GPS module can automatically or (and) manual input of latitude and longitude, a database is stored in the CPU module, this database records the sun exposure of different longitudes and latitudes and different years, months, days, and times Angle, the CPU module can also receive the year, month, day, time signal of the time module and the latitude and longitude signal of the GPS module, and then compare it with the stored database to find out the angle of the sun, and after calculation and processing, output an electrical signal to the sunlight receiver for adjustment device. The sunlight receiver adjustment device includes a base (4), a sunlight receiver (1), an adjustment rod (2), an adjustment motor (3), etc., the adjustment motor receives the electrical signal sent by the CPU, and the length of the adjustment rod is changed to adjust the sunlight receiver angle to achieve sunlight tracking.

Detailed ways

Before using the present invention, it is necessary to adjust the level and direction first, then fix it, input the local longitude and latitude and confirm the year, month, day and time, the signals of the time module and the GPS module are sent to the CPU module, and the CPU module and its stored Compare the database to find out the angle of the sun, and output the electrical signal to the adjustment motor after calculation and processing. The adjustment motor receives the electrical signal sent by the CPU module, and the length of the adjustment rod is changed to adjust the angle of the sun receiver, so as to realize the tracking of the sun. .
