摘　　要：为解决工程爆破中时间同步精度不足,导致爆破效果不理想的问题,研究提出了一种基于分布式网络的爆破控制系统。该系统采用FPGA作为核心控制器,通过改进的时间同步协议(PTP协议),确保各节点之间的高精度时间同步。此外,系统利用低压差分信号(LVDS)技术实现远距离数据传输,确保信号在复杂地形或环境下依然能够保持稳定传输和同步。爆破网络的各终端能够生成精确到纳秒级的延迟同步信号,从而保证所有爆破点在预定的时刻精确同步起爆,实现爆破效果的最大化。与传统的爆破同步方法相比,该系统不仅显著提高了同步精度,且在恶劣环境下仍能保持稳定运行。实验结果表明,该系统在各种复杂环境中都能稳定运行,时间同步精度达到了纳秒级,有效提升了爆破过程的安全性、一致性和可控性。该研究为解决工程爆破中的时间同步问题提供了一种创新且有效的方案,并为未来进一步提升爆破技术的精度和可靠性提供了理论依据和实践参考。In order to solve the problem of insufficient time synchronization accuracy in engineering blasting,which leads to unsatisfactory blasting effect,this study proposes a distributed network-based blasting control system.The system adopts FPGA as the core controller,and ensures high-precision time synchronization among nodes through an improved time synchronization proto⁃col(PTP protocol).In addition,the system utilizes low-voltage differential signaling(LVDS)technology to achieve long-distance data transmission,which ensures that the signal can still maintain stable transmission and synchronization in complex terrains or en⁃vironments.The terminals of the blasting network can generate delayed synchronization signals accurate to the nanosecond level,thus ensuring that all the blasting points in a predetermined moment of precise synchronization of the explosion,achieving the maxi⁃mum effect of blasting.Compared with traditional blasting synchronization methods,this system not only significantly improves the synchronization accuracy,but also maintains stable operation in harsh environments.Experimental results show that the system can operate stably in a variety of complex environments,and the time synchronization accuracy reaches the nanosecond level,which ef⁃fectively improves the safety,consistency and controllability of the blasting process.This study provides an innovative and effective solution to the time synchronization problem in engineering blasting,and provides a theoretical basis and practical reference for fur⁃ther improving the precision and reliability of blasting technology in the future.
