摘　　要：随着社会发展和科技进步,研究人员发现激光网络在目标信号转换和传输方面有着得天独厚的作用,对激光网络目标信号的同步传输,能够有效提高目标信号的处理效率。因此,设计稳定高效的激光网络目标信号同步传输系统,激光驱动器驱动激光网络中被试品的目标信号,通过激光探测器中进行调制、转换处理,并通过FPGA和总线实现目标信号的采集和传输,同步控制模块通过AVR处理器和FPGA处理器检测、存储目标信号,并采用同步比例传输方法,确保激光网络目标信号的同步传输。实验结果表明,该同步传输系统故障消除率、同步传输精度均高于对比系统,明显提高了目标信号的传输效率和稳定性。With the development of society and the progress of science and technology,researchers have found that laser network has a unique role in target signal conversion and transmission. Synchronized transmission of target signal in laser network can effectively improve the processing efficiency of target signal. Therefore,a stable and efficient laser network target signal synchronization transmission system is designed. The laser driver drives the target signal of the test object in the laser network,modulates and converts the target signal through the laser detector,and collects and transmits target signal through the FPGA and the bus. The synchronization control module detects and stores target signal through the AVR processor and the FPGA processor. The step-by-step proportional transmission method ensures synchronous transmission of target signal in laser network. The experimental results show that the fault elimination rate and synchronous transmission accuracy of synchronous transmission system are higher than those of comparative system,and the transmission efficiency and stability of the target signal are obviously improved.
