便携式数字水位传感器无线变送器的设计

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。而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，本文提出了基于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，极大的扩展了感应式数字水位传感器的应用范围。

Design of Wireless Portable Transmitter for Digital Water-level Sensor

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 is proposed in this paper, based on the ZIGBEE wireless communication technology. 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 introducing 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, greatly extends the applications of the digital water-level sensor.
