Abstract

The invention belongs to the field of domestic security, environmental monitoring wireless alarming system, characterized in that it at least comprises a monitoring host computer, a base station, a GSM/GPRS modem and several intelligent nodes, where the intelligent nodes are used to detect indoor temperature, humidity, fire alarm, gas leakage and illegal invasion and are composed of sensor plate, microcontroller unit, radio frequency communication module and power supply module, the base station and the intelligent nodes intercommunicate any one of the three protocols of sMAC, IEEE 802.15.4 and ZigBee and the base station transmits the sampled data of the intelligent nodes to the monitoring host computer; and the monitoring host computer is installed with monitoring application software, and has defence setting and withdrawing switching button to control the base station, and also has phone number keying-in and modifying function and a fuction fo giving an alarm to users by phone short messages.

Description

technical field [0001] The invention belongs to a monitoring system based on a wireless sensor network, in particular to a home security and environment monitoring and alarm system. Background technique [0002] The rapid development and increasing maturity of microelectronics technology, sensor technology and network communication technology have made it possible to manufacture a large number of smart microsensors with small size, low power consumption, and multiple functions such as perception ability, computing ability and communication ability. These new-generation smart sensor nodes (referred to as smart nodes) can perceive the surrounding environment, process data, and communicate with each other through wireless communication modules. A wireless sensor network is a network composed of a large number of intelligent nodes. It is an emerging hot research field with a high degree of cross-discipline, and is considered to be one of the most important technologies in the 2...
