Example Embodiment

[0032] The present invention includes two types of node designs, namely the design of the sink node and the design of the gateway node. Both of these two kinds of nodes are composed of four main modules. The constituent modules of the sink node include: a processor module, a short-range wireless communication module, a long-range wireless communication module, and a power supply module. The gateway node also includes a processor module, a long-distance wireless communication module, and a power supply module, as well as an Internet access module. The sink node is generally placed within 100 meters from the wireless sensor network, and receives the data sent by the wireless sensor network through the short-range wireless communication module, and then the processor converts the protocol, and finally sends it out through the long-range wireless communication module. The gateway node is generally placed within 100 meters from the Internet access station, and receives the data sent by...

Abstract

A kind of connection device between wireless sensor network and internet is mainly used to resolve problem of communication between wireless sensor network and internet. The device includes two kinds of nodes: convergent node and gateway node. The main functions of the two kinds of nodes are converting protocols, and it possesses following characters: the convergent node possesses two communication modules which are close quarters wireless communication module and remote distance wireless communication module, the former is used to receive data from the wireless sensor network, the later is used to send data to gateway node, the processor chip is used to accomplish the conversion between close quarters wireless communication protocol and remote distance wireless communication protocol; the network node possesses a remote distance wireless communication module and a internet module, the former is used to receive data from the convergent node, the later is used to send data to the internet, so the processor chip is used to accomplish the conversion between remote distance wireless communication protocol and TCP/IP protocol.

Description

technical field [0001] The invention relates to a solution for communication between two networks using different protocols, and belongs to the intersecting field of embedded development and computer network technology. Background technique [0002] Wireless Sensor Network (WSN for short) is the product of the development and integration of information technology such as microelectronics technology, AdHoc wireless network, and distributed computing. It uses low-cost, low-power, and computable wireless sensor network nodes to collect and process the data of monitoring objects that users are interested in, and sends the collected data to users in an ad hoc multi-hop network transmission mode. It has broad application prospects in the fields of military, environmental monitoring, medical treatment, agriculture and mining. [0003] The main characteristics of wireless sensor network nodes are miniaturization, low power consumption, and low cost. At present, there are not many ...
