摘要
本论文研究基于MSP430的短距离多模光纤多点检测系统,设计了光纤通信链路的软硬件、数据采集软硬件和单总线传输协议,该系统由传感器模块,MSP430模块,光调制模块,多模光纤模块,光解调模块,显示模块等组成。使用HFBR-1414T发射模块将电信号转化为光信号进行光纤传输,再通过HFBR-2414T接收模块将激光信号转化为电信号。在实际的实验中,实现了压力及温湿度数据采集和1 km数据传输,经过该试验表明,该系统具有较高的可靠性和准确性,低成本,稳定性好。
The paper studies short multimode fiber multipoint detection system based on MSP430, design the software and hardware, data acquisition hardware and software of fiber optic communication link and a single bus transmission protocol. The system consists of sensor module, MSP430 module, light modulation module, multimode optical fiber, optical demodulation module, display module, etc. Using HFBR-1414-T launch module converts electrical signals into light signal optical fiber transmission, through HFBR-2414-T receiving module will laser signal into electrical signal. In the actual experiments, has realized the lkm of the data acquisition and transmission, the experiment shows that this system has high reliability and accuracy, low cost, good stability.
