s1, respectively electrifying an information encoding module (23), a wireless receiving antenna (17), a central processing unit (18) and a data information processing unit (19) through a power module (25);
s2, coding and converting information to be transmitted through an information coding module (23), modulating the converted coded information into ultraviolet light with a certain frequency and wavelength through an information modulation module (22), and then transmitting the ultraviolet light to the outside through an ultraviolet detector (21);
s3, capturing and receiving external ultraviolet signals by the wireless receiving antenna (17), and enhancing and concentrating the external ultraviolet signals by the arc-shaped cover (15) and the arc-shaped light collecting plate (16);
s4, when people need to catch signals in different directions outside, the people can operate the control switch to enable the central processing unit (18) to control the adjusting motor (6) to start to work, the adjusting motor (4) drives the first bevel gear (4) to rotate through the second belt pulley (7), the first belt pulley (5) and the rotating shaft (3), the first bevel gear (4) drives the second transmission gear (13) to rotate through the second bevel gear (10), the transmission shaft (9) and the first transmission gear (11), and the second transmission gear (13) drives the wireless receiving antenna (17) to slowly rotate through the rotating shaft (8), the fixed sleeve (12) and the connecting rod (14) respectively;
s5, after the ultraviolet signals are captured by the wireless receiving antenna (17), the wireless receiving antenna (17) transmits the ultraviolet signals to the central processing unit (18), and the central processing unit (18) transmits the ultraviolet signals to the data information processing unit (19) for processing;
s6, a pulse counter (191) in the data information processing unit (19) counts the received ultraviolet signals, a phase-locked loop (192) locks the frequency of the received ultraviolet signals, a symbol/time slot synchronization module (193) continuously receives and synchronizes the received ultraviolet signals, the received ultraviolet signals are decoded by an information decoding module (194), and the decoded data information is buffered and transmitted to a display (24) for display through a data buffer module (195) respectively, so that people can read the information conveniently.
