Aiming　at　the　problems　of　most　meters　without　wireless　communication　interfaces,　an　embedded　wireless　communication　interface　based　on　2.4　GHz　Wireless　Communication　Technology　is　designed　for　single-phase　electronic　watt-hour　meter　in　this　paper.　The　interface　consists　of　nRF2401　chip　and　PIC16F690　and　the　peripheral　circuits.　It　adopts　DL/T　645　protocol　which　has　good　openness　and　receives　meters＇　data　by　interrupt　mode,　which　raises　the　utilization　rate　of　CPU.　The　interface　also　has　some　features　of　small　volume,　low　cost,　high　communication　speed,　high　stability　and　reliability,　and　the　communication　distance　can　meet　the　need　of　automatic　meter　reading.　Some　possible　engineering　problems　are　taken　into　account　in　design,　including　data　loss　in　communication,　the　problems　of　communication　conflict,　electricity　data　length　over　the　data　width　configured　in　nRF2401　and　so　on.　It　makes　the　interface　designed　valuable　in　practical　application.
