Background technology
Due to the acceleration of Urbanization in China, the building of modernization more and more occur in city, the work of people
Becoming increasingly dependent on building as life, the time is all spent in building greatly.
On the one hand, building environmental amenity, safety etc. are especially paid attention to by people.It is directed to this, in the prior art,
The most commonly used monitoring system for environment is monitored and sends when producing unusual condition alarm signal, such as, apply
Fire alarm equipment in interior architecture thing, gas leakage alarm device, cigarette sense alarm device, burglar alarm etc., with
And it is applied to the atmosphere quality monitoring device etc. of outdoor.
On the other hand, along with the aggravation that world energy sources is the most in short supply, the energy saving of building also seems and is even more important.It is directed to
This, in the prior art, can be the fortune of the electrical equipment such as central air-conditioning, refrigerator by effectively monitoring building environment
Row provides reference, and energy-saving and emission-reduction are played positive impetus.
Sensing network is the wired or wireless network being made up of with free configuration mode one group of sensor, its objective is to work in coordination with
Ground perception, gather and process the information of perceptive object in the geographic area of the network coverage, and converge to observer.Sensor, net
The process of network technology and information is three fundamentals of sensing network;Complete perception task one group of sensor synergism;Wired network
Network or wireless network between sensors, transmit data and control command between sensor and control centre;To initial data
Statistics, analyze on the basis of form decision-making and control, to realize the function of information processing.
