一种基于单总线技术的深基坑承压水监控系统设计

Design of Monitoring System for Confined Water in Deep Foundation Pit Based on 1-wire Technology

单总线网络具有成本低、连接便捷、稳定可靠的特点,广泛应用于多点传感应用的场合。本文提出了一种基于单总线技术的深基坑承压水监控系统解决方案,将无线GPRS引入单总线网络,克服了纯单总线扩展性差,灵活性不足的问题。该方案具有组网灵活的特点,可实时监测基坑井点管内水位,减小基坑的总涌水量,可为基坑施工安全提供技术保证,具有较好的应用开发前景。

1-wire network has the characteristics of low cost, convenient connection, stability and reliability, which is widely used in the application of multi-point sensor. In this paper, a solution of deep foundation pit confined water monitoring system based on1-wire technology is proposed. Wireless GPRS is introduced into 1-wire network, which overcomes the problems of poor scalability and flexibility of pure single bus. The scheme has the characteristics of flexible networking, real-time monitoring of water level in the well point pipe of the foundation pit, reducing the total water inflow of the foundation pit, providing technical guarantee for the construction safety of the foundation pit, and has a good prospect of application and development.
