Abstract

The invention discloses an embedded wireless sensor network gateway comprising an S5PV210 processor, a remote monitoring computer, a WSN coordinator node, an LCD display, a NAND FLASH EEPROM storage chip, a communication interface unit, a power module and a reset circuit. The gateway device accesses the Internet via the Ethernet; a WSN coordinator is connected with the gateway by a UART, the gateway is connected with the remote monitoring computer by a network for realizing remote data transmission and information resource sharing though TCP / IP; and the gateway device realizes the online update and maintenance of remote or local system software through USB communication or Ethernet communication. The gateway works stably, is simple and practical, is easy to maintain and has a wide application value.

Description

technical field [0001] The invention belongs to the technical field of communication and relates to an embedded wireless sensor network gateway, in particular to a wireless sensor network gateway based on an ARM CortexA-8 embedded platform. Background technique [0002] Wireless sensor network (WSN) is a multi-hop self-organizing network system composed of a large number of miniature sensor nodes through wireless communication. information and send it to users. However, if the wireless sensor network is really put into use, it cannot exist completely in isolation. It needs to be connected to the external network through the gateway device to realize the remote transmission of data and achieve the intercommunication and sharing of information resources. [0003] As a bridge between wireless sensor network and external network, gateway plays a very special and critical role in WSN. Currently, there are two main types of gateway designs. One is to add transmission modules, s...
