In the hardware design, the common between different kinds of nodes is fully considered, and the universal module is used to realize the unified structure of main control CPU board, power management interface card and wireless network access interface card. 在硬件设计中充分考虑了不同种类节点之间的共性,采用通用模块为节点实现了统一架构的主控CPU板卡、电源管理板卡、无线网络接入板卡。
