3G-ZigBee communication gateway

The utility model is a 3G-ZigBee communication gateway. The 3G-ZigBee communication gateway comprises a ZigBee wireless radio frequency module, a central processor unit, a 3G communication module, a first key module and a power supply module, wherein the signal output end of the ZigBee wireless radio frequency module is connected with the input end of the central processor unit, the input end of the central processor unit is further connected with the first key module, the output end of the central processor unit is connected with the 3G communication module, and the power supply module supplies power to the ZigBee wireless radio frequency module, the central processor unit, the 3G communication module and the first key module. The power supply module provides an alternating current power supply mode and a battery power supply mode for the gateway to select. The 3G-ZigBee communication gateway is low in power consumption, suitable for connection of various ZigBee networks and 3G networks, and capable of enlarging the covering range of the networks. Besides, the 3G-ZigBee communication gateway can select the alternating current power supply mode and the battery power supply mode according to the application environment. Thus, the layout of the gateway can be more flexible, and the gateway is higher in practicability and can adapt to different geographical environments.
