摘　　要：讨论了羊八井大型高海拔宇宙线探测实验(Large High Altitude Air Observatory,LHAASO)的水切伦科夫探测器阵列(water Cherenkov detector array,WCDA)分布式电子学系统原理。并设计了一个包括两个原型模块的原理验证电子学系统,用于验证相关原理,包括远距离大范围时钟分配方案和回声原理的校准方法。测试结果表明分布式电子学原理满足WCDA实验需求,并将运用到实际工程设计中。A distributed electronics system is discussed, which is expected to have a high performance in the water Cherenkov detector arrays （WCDAs） in the Large High Altitude Air Observatory （LHAASO） project. A prototype system consisting two modules is developed to evaluate the principles of main techniques on the distributed architecture, including clock distribution within a big scale in dimension and online transmission delay calibration. The results are positive and the integrate system will be developed later.
