Double-shaft high-precision solar tracking motor controller

Abstract

The invention discloses a double-shaft high-precision solar tracking motor controller, which includes a power interface, a singlechip and a circuit board, wherein photosensitive sensors and four relays are arranged on the circuit board; the photosensitive sensors are positioned on the peripheries of the relays; the relays are positioned above the circuit board; the photosensitive sensors are positioned under the circuit board; light transmitting holes are formed in the circuit board; the photosurfaces of the photosensitive sensors face upwards; the photosensitive sensors receive sunlight through the light transmitting holes; the power interface is connected with the singlechip through the power switching circuit; the singlechip receives signals of the photosensitive sensors and sends control signals to the corresponding relays; and the relays receive the control signals and then enable the motor to stop rotating or rotate leftwards, rightwards, downwards and upwards. The double-shaft high-precision solar tracking motor controller is used for measuring the solar azimuth based on the solar ray rectilinear propagation and photoeffect principles, automatically tracks the sun, and can be operated manually in a remote manner, achieves the auto-tracking accuracy within 3 degrees, and guarantees the solar thermal utilization of the maximum efficiency.

Description

technical field [0001] The invention relates to the measurement of the sun orientation, in particular to a high-precision sun tracking device. Background technique [0002] The world's energy system is basically dominated by oil, coal mines and natural gas, which are non-renewable resources. With the development of human beings and the progress of society, the dependence on energy is gradually increasing, especially oil. After the 1950s, due to the outbreak of the oil crisis, which had a huge impact on the world economy, international public opinion began to pay attention to the world's "energy crisis". Many people even predict that the world's oil resources will be exhausted, and the energy crisis will be inevitable. If major efforts are not made to utilize and develop new energy sources, human beings will face a serious problem of energy shortage in the near future. New energy must meet two conditions at the same time: first, the reserves are abundant and will not be ex...
