Abstract

The disclosed gateway device for wireless sensor network comprises: a GPRS communication unit to communicate between the gateway and Internet or wireless communication network, a wireless RF transceiver for gateway and wireless sensor network, and a MPU to control the communication of former two units, wherein the MPU uses UART (general asynchronous serial interface) to communicate with the GPRS unit and SPI (synchronous serial interface) to communicate with the RF transceiver. This invention realizes reliable remote connection and bidirectional transmission for request in real application.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a wireless sensor network gateway device. Background technique [0002] With the rapid development and maturity of communication technology, embedded computing technology and sensor technology, miniature sensors with perception, computing and communication capabilities begin to appear around the world. Randomly distributed tiny nodes integrated with sensors, data processing units and communication modules form a network through self-organization, and measure thermal, infrared, sonar, radar and seismic waves in the surrounding environment with the help of various types of sensors built into the nodes Signals to detect many material phenomena of interest to us, including temperature, humidity, noise, light intensity, pressure, soil composition, size, speed, and direction of moving objects. [0003] In terms of communication methods, although miniature sensors can ...
