数字水位传感器无线变送器的设计方案

　　感应式数字水位传感器在传统的应用中，采集数据的传输都是采用有线传输。由于传统有线网络本身的局限性，许多特殊的环境下网络覆盖和网络支持仍然是个难题。针对这个问题，提出了基于ZigBee无线通信技术的便携式数字水位传感器无线变送器的设计方案。该变送器体积小，成本低，可操作性强，现场安装简单。由于采用ZigBee技术，更加适合组建有大量的现场数据采集点的监控系统，且组网灵活，极大地扩展了感应式数字水位传感器的应用范围。

　　Abstract:

　　In traditional applications of inductive digital water-level sensor， data acquired was transmitted by wire transmission. Owing to the limitations of traditional cable-Network itself， the coverage and technical support of cable-network is still a problem in many special circumstances. To address this issue， the design of wireless transmitter of portable digital water-level sensor based on ZigBee wireless communication technology is proposed in this paper. There are many advantages of this transmitter， such as small size， lower cost， easy operation， simple on-site installation， and so on. As a result of adopting the ZigBee technology， it is more suitable to construct a monitoring system of a large amount of on-site data collection point and flexible to construct network， and greatly extends the applications area of the digital water-level sensor.
