Zigbee　technology　is　a　kind　of　bi-directional　wireless　communication　technology　characterized　by　low　complexity,　low　power　consumption,　close　distance,　low　speed　and　low　cost.　It　is　mainly　used　for　data　transmission　with　low　power　consumption,　low　transmission　speed　and　short　distance,　as　well　as　application　of　typical　periodic　data,　low　reaction　time　data　and　intermittent　data　transmission.　This　article　presents　a　design　of　intelligent　power　supply　unit　system　based　on　zigbee　technology.　The　system　is　composed　of　end　devices,　zigbee　wireless　network,　wireless　/　Internet　gateway　and　server.　The　goal　of　the　system　is　to　manage　power　supply　to　equipments　automatically,　and　to　develop　the　safety　level　of　the　work　environment.　Finally　this　article　gives　an　analysis　of　the　management　and　maintenance　of　the　system,　so　as　to　contribute　to　further　studies.
