感應(yīng)式數(shù)字水位傳感器在傳統(tǒng)的應(yīng)用中，采集數(shù)據(jù)的傳輸都是采用有線傳輸。由于傳統(tǒng)有線網(wǎng)絡(luò)本身的局限性，許多特殊的環(huán)境下網(wǎng)絡(luò)覆蓋和網(wǎng)絡(luò)支持仍然是個難題。針對這個問題，提出了基于ZigBee無線通信技術(shù)的便攜式數(shù)字水位傳感器無線變送器的設(shè)計方案。該變送器體積小，成本低，可操作性強，現(xiàn)場安裝簡單。由于采用ZigBee技術(shù)，更加適合組建有大量的現(xiàn)場數(shù)據(jù)采集點的監(jiān)控系統(tǒng)，且組網(wǎng)靈活，極大地擴展了感應(yīng)式數(shù)字水位傳感器的應(yīng)用范圍。

　　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.
