摘　　要：变形监测作为大坝安全状态感知的重要手段,具有测值直观、能全面反映大坝安全状态等特点,对保障大坝长期安全稳定运行具有重要的意义。目前大坝水平位移自动化监测主要使用引张线法、真空激光准直法及垂线法。尽管CCD垂线坐标仪已在大坝工程实践中广泛应用,可该仪器存在不支持现场配置、现场实时数据读取等不足,且无直接远程交互功能,需要接入其他采集装置或转接设备才能进行远程通信。本文设计的智能式CCD垂线坐标仪运用微处理器及以太网接口,不需要接入其他采集设备,可直接接入软件系统,解决了仪器集成复杂、传统通信方式不稳定等问题;并运用蓝牙通信和智能手机APP,解决了现场参数配置、实时采集显示的问题;提出了一种反馈式自适应调光技术,提高了仪器的自适应性和稳定性。Safety monitoring plays a crucial role in ensuring the safe and stable operation of water conservancy projects,serving as a fundamental prerequisite for achieving intelligent water conservancy.By directly capturing the displacement(or deformation)response of building structures under external loads,deformation monitoring offers a direct reflection of building safety.Currently,automatic monitoring of dam horizontal displacement primarily relies on the tension line method,vacuum laser alignment method,and vertical line method.The CCD vertical coordinate instrument has seen widespread use in dam engineering practice;however,it suffers from drawbacks such as the lack of on-site configuration and real-time data reading capabilities,and the absence of direct remote interaction function.This necessitates the use of auxiliary acquisition devices or switching devices for remote communication.To address these limitations,we designed an intelligent CCD vertical coordinate instrument with a microprocessor and Ethernet interface,eliminating the need for connection to additional acquisition equipment and enabling direct connectivity to the software system.This solution effectively resolves issues related to complex instrument integration and the unstable nature of traditional communication modes.To address field parameter configuration,real-time acquisition and display challenges,we employed bluetooth communication and a smartphone APP in designing this instrument.Furthermore,we propose an adaptive dimming technique to enhance the instrument’s self-adaptability and stability.
