摘要
提出一种基于ZigBee无线通信技术的深基坑降排水控制系统。系统设计了ZigBee协调器节点、路由节点以及监控节点,采用树簇拓扑结构,基于分布式地址分配机制给出节点网络地址的分配方式,并分析基坑控制系统的主要工作流程。该方案组网灵活,可实时监控深基坑井点管内水位的变化,远程控制潜水泵的启停,确保深基坑坑内水位在安全高度,尽可能地减小基坑的总涌水量,降低基坑排水施工的难度,保证施工安全,具有较好的应用前景。
In this paper,a drainage control system for deep foundation pits is proposed on the basis of ZigBee wireless communication technology. The nodes of ZigBee coordinator,router and monitor are designed and the tree topology is adopted. IP address of the nodes are given based on the distributed address allocation mechanism and then the main work process of the control system for foundation pit is analyzed. Because of the flexible networking of this system,water-level fluctuation in the well points of deep foundation pits can be monitored in real time and the submersible pumps can be started and stopped with the long-rang control so as to ensure the water in deep foundation pits at a safe level and keep the water inflow as low as possible. The system will make the work of drainage in pits easier and guarantee the safety of the work,thereby being promising in practical application.
