WSN gateway supporting multiple frequency bands and multiple communication modes

Abstract

The invention relates to a WSN gateway supporting multiple frequency bands and multiple communication modes, and belongs to the technical field of wireless communication. The gateway comprises an extranet access unit, a master control unit, a WSN radio frequency access unit and a power supply management unit. The extranet access unit comprises 3G, WiFi and the ethernet and is used for uploading data of a wireless sensing network to an upper computer through three different transmission paths so that remote monitoring of internal nodes of the wireless sensing network can be realized, and the upper computer can also directly access and control the internal nodes of the wireless sensing network. The master control unit is used for processing data packages of various protocol types in the gateway so that system scheduling, management and control can be completed. The WSN radio frequency access unit is composed of wireless radio frequency modules of 433MHz, 470MHz, 780MHz and 2.4GHz frequency bands and responsible for networking of four frequency bands and management and data interaction of node equipment. The power supply management unit is responsible for supplying working power for the whole gateway system. According to the gateway, various types of network equipment can stably access to the internet so that centralized control and management of various network systems can be realized.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a WSN gateway supporting multiple frequency bands and multiple communication modes, in particular to a WSN gateway supporting four frequency bands in downlink and three communication modes in uplink. Background technique [0002] The gateway plays an important role in the development of wireless communication communication technology. The process of wireless data collection and information transmission involves fieldbuses with different structural types of protocol stacks, and the gateway is to provide data when communicating with fieldbuses using different protocols. Equipment for switching and protocol conversion functions. Traditional control devices can be connected to Ethernet and other network devices through gateways without considering compatibility issues with other heterogeneous networks. It realizes the transparent transmission of data between different n...
