Electronic answering system based on ZigBee protocol

The invention discloses an electronic answering system based on a ZigBee protocol. The electronic answering system comprises at least one router, at least one hand-held terminal and a coordinator which is used for authentication of the router and the hand-held terminal, wherein routers are connected with one another or connected with the coordinator, the hand-held terminal is connected with the at least one router or the coordinator, the coordinator receives and stores messages which are sent by the terminal or forwarded by the at least one router, and sends messages to the hand-held terminal, and the hand-held terminal receives the messages which are sent by the coordinator or forwarded by the at least one router. According to the electronic answering system based on the ZigBee protocol, the whole system is based on the ZigBee protocol, signal transmission is stable and reliable, a ZigBee network is formed by the coordinator and a plurality of routers, the network capacity is high, the expandability is good, weak signals and dead zones can be effectively removed, requirements for the hand-held terminal are low, and the matched hand-held terminal is small in size and convenient to carry about.
