研究目的
To propose a laser wireless communication solution based on single chip microcomputer for short-range wireless optical communication.
研究成果
The design and implementation of a wireless optical communication device based on single-chip microcomputer, combining laser transmission technology, laser receiving technology, and single chip microcomputer technology, enhances the communication reliability of the system and reduces the bit error rate. A reliable transmission of the communication is completed under the condition that the 7.2 m internal emission power is 5 mW, and Beam divergence is 170 mrad.
研究不足
The system's effective communication distance is limited to 7.2 m under specific conditions. The received signal level drops significantly at distances beyond 7 m due to large divergence angle.
1：Experimental Design and Method Selection:
The system adopts STC12C5A60S2 MCU as the main control chip and encodes laser as communication carrier.
2：Sample Selection and Data Sources:
Uses a CW Laser as the light source and a Pseudo-Random Bit Sequence Generator for signal generation.
3：List of Experimental Equipment and Materials:
Includes STC89C52RC microcontroller, laser driving circuit, laser array light source, photodiode, and Optisystem software for simulation.
4：Experimental Procedures and Operational Workflow:
The modulated signal passes through the atmospheric channel to the receiving end, receives the signal through the PIN detector and the TIA amplifier, and uses the BRE Analyzer to test its error performance.
5：Data Analysis Methods:
The system's bit error rate and Q values are analyzed to evaluate communication performance.
