摘要
为了智能监控河流、湖泊等水系统液位,提出了一种基于感应式数字水位传感器的无线监测系统,介绍了系统设计原理和实现基本方法,该系统采用低电压、超低功耗的MSP430单片机作为处理核心,实现了数据的实时采集、发送;采集的信息通过ZigBee网络平台传送到远程监控中心,监控中心采用LabVIEW上位机做监控和控制系统;设计实验条件如下:硬件测试条件包括一台装LabVIEW的笔记本电脑,通过RS232串口与中心协调器连接,一个监测终端、一个中继路由,两个长度为1m且每两个触点之间的距离为1cm的感应式数字水位传感器,传感器分别接在监测终端,经测试该系统具有稳定性好、灵活性强、易操作等优点,有良好的应用前景。
In order to monitor water level of water Supply System like rivers and lakes, this paper introduces a monitoring system of water supply based on inductive digital water-level sensor , then ZigBee module transmit data to control terminals. The upper computer can a- chieve functions like Monitoring and control by LabVIEW . The principle of system design and implementation method are described. The system uses MSP430 as the controller for real-time data collection and transmission. We designed an experiment, a computer with LabVIEW software, connected via RS232 serial port and center coordinator, a monitoring terminal, a relay route , two lengths of 1 m and a distance of 1 cm between each two contacts induction type digital water level sensor, sensors were connected to the monitoring terminal. The test show the system has good stability, flexibility, easy to pperate, wide application scope and has better application prospect.
