Design of Serial Communication Module Based on Solar-Blind UV Communication System

UV communication is a wireless optical communication technology which bases on the scattering and absorption of UV light in atmospheric. It combines the advantages of traditional optical communications and wireless communications, including non-line-of-sight (NLOS), anti-interference, low wiretapping and electromagnetic silent. With a wide range of serial communications for remote monitoring and control, the demand for serial communications is increasing in engineering applications. This paper presents the application of serial port in non line-of-sight UV communications to meet the requirements of low-rate, short-range communication. A serial communication interface based on Altera Company’s Cyclone II series FPGA chip (EP2C35F672C6) has been designed. The Universal Asynchronous Receiver Transmitter (UART) module is generated by the Verilog HDL programming language in the integrated software development environment (Quartus II 9.0). Simulation and debugging results indicate that it shows good functions and satisfies protocol requirements.
