Multi-protocol multi-interface wireless sensor network gateway

Abstract

The invention discloses a multi-protocol multi-interface wireless sensor network gateway and relates to the technical field of a wireless sensor network. The gateway mainly consists of an embedded processor, an SDRAM (Synchronous Dynamic Random Access Memory), a Flash memory, a WiFi (Wireless Fidelity) wireless radio frequency transceiver module, a ZigBee wireless radio frequency transceiver module, a GPRS (General Packet Radio Service) module, a Bluetooth module, a GPS (Global Positioning System) data acquisition module and an Ethernet interface control module. A networked operating system Linux is used as an operating system of the multi-protocol multi-interface wireless sensor network gateway and can be compatible with a TCP / IP (Transmission Control Protocol / Internet Protocol) protocol IPv6 (Internet Protocol Version 6). The multi-protocol multi-interface wireless sensor network gateway has the advantages that conversion among various protocols is completed by treatment of a design protocol conversion program; the multi-protocol multi-interface wireless sensor network gateway can be used for setting up networks with various architectures, interconnecting the networks with various architectures and transmitting data; various network access schemes are provided for the wireless sensor network; the multi-protocol multi-interface wireless sensor network gateway has strong anti-interference capability, low power consumption and small volume; and portable equipment is provided for interconnection among the networks with various architectures and building of an integrated network.
