摘　　要：针对传统的液位测量仪表大多不具备无线通信功能、在复杂环境中不易布线的问题,提出了一种具有GPRS通信功能的无线超声波液位测量系统的设计方案。该系统采用LM3S811作为主控器件,将超声波液位测量电路采集的数据通过GPRS通信模块传输至监控中心的服务器端;服务器端采用JSP技术进行动态网页开发,其后台通过访问SQL Server数据库存储信息。测试结果验证了该系统的可行性。In view of problems of no wireless communication function and uneasy routing in complex environment existed in traditional liquid level measuring instruments, the paper proposed a design scheme of wireless ultrasonic-wave liquid level measuring system with GPRS communication function. The system uses LM3S811 as main control device which transmits data collected by ultrasonic-wave liquid measuring circuit to server of monitoring center through GPRS communication module, and the server uses JSP technology to develop dynamic Web page and its background stores data through accessing SQL Server database. The test result validated feasibility of the system.
