A real-time monitoring system for the curved bridge transverse displacement was designed because most studies in China for curved bridge transverse displacement are the qualitative analysis in theory,few researchers made efforts for real-time monitoring system for the actual lateral displacement of curved bridges,and most of the existing bridge monitoring systems are to monitor the immunity of the bridges. This system is divided into two parts:lower computer(composed of linear displace-ment sensor and wireless sensor network) and upper computer (composed of lower computer data browsing,storage manage-ment,real-time display softwares designed with C # language). The simulation testing results indicate that the system can per-form real-time monitoring and reflect the dynamic changes of the curved bridge transverse displacement.%国内大多数对曲线桥横向位移的研究都是从理论上定性分析，很少有针对曲线桥梁实际横向位移的实时监测系统，而现行的桥梁监测系统大多是对桥梁的扰度进行监测，因此设计了一种针对曲线桥桥梁的横向位移的实时监测系统。该系统分为两个部分：由直线位移传感器和无线传感网组成的下位机部分，以及用C#语言设计的下位机数据的浏览、存储管理、实时显示软件组成的上位机部分。通过模拟测试，该系统能实时地监测反映出曲线桥横向位移的动态变化。
