Wireless sensor network gateway device with 3G remote transmission

Abstract

The present invention discloses a wireless sensor network gateway with 3G remote transmission, comprising a 3G wireless communication unit, a ZigBee wireless radio frequency transceiving unit, a touch screen interface control unit, an ARM11 embedded processor control unit, a USB interface and SD card interface control unit and a button interface control unit. The 3G wireless communication unit uses a SIM5210 chip; the wireless radio frequency transceiving unit uses a CC2530 chip and a CC2591 chip; the AEM11 embedded processor control unit uses a S3C6410 chip; and the touch screen interface control unit uses AT043TN24V.1 chip. The effective wireless communication distance of the gateway device of the present invention accessing into a ZigBee network node is 700-1000m, the wireless connection of the ZigBee network node and Internet is realized, so that the gateway arranging geographical position is more flexible; the wireless sensor network gate device is particularly suitable for monitoring areas having difficulty and inconvenience in laying wired communication cables or optical cable auxiliary equipment; the gateway has stronger practicability, and the relevant information of a gateway can be accessed in a remote wireless webpage manner.

AI Technical Summary

Problems solved by technology

The effective wireless communication distance of traditional gateways accessing ZigBee network nodes is within 100 meters, which limits the deployment location of gateways

And the ZigBee network is generally connected to the Internet by wired communication, so it is not suitable for monitoring areas where wired communication cables or optical cables are difficult and inconvenient to lay; although wireless GPRS is also used to forward monitoring data in SMS, the amount of forwarding monitoring data is small. The gateway device cannot be accessed and remotely controlled and managed via the webpage
