Title:
PHOTOCELL IRRADIATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/007927
Kind Code:
A1
Abstract:
A photocell irradiation sensor, comprising: a photocell selection circuit (10), a main control chip (20) electrically connected to the photocell selection circuit (10), an irradiation sampling circuit (30) electrically connected to the main control chip (20), a maximum power tracking circuit (40), an energy storage circuit (50), and a wireless communication module (60), wherein the maximum power tracking circuit (40) is also electrically connected to the energy storage circuit (50); the main control chip (20) controls, according to an "irradiation detection" or "power supply" function to be realized, the photocell selection circuit (10) to turn on or turn off the connection between a photocell and a subsequent circuit; when the main control chip (20) selects the "power supply" function, the main control chip (20) controls the maximum power tracking circuit (40) to enable the photocell to work at the maximum power position to output electrical energy, and the electrical energy is stored by means of the energy storage circuit (50), so as to facilitate the power supply of the energy storage circuit (50) to the other components; when the main control chip (20) selects the "irradiation detection" function, the irradiation sampling circuit (30) transmits an irradiation signal to the main control chip (20) for measurement; and the wireless communication module (60) sends the measured irradiation value in a wireless communication manner.
