Hardware Design Of Family Security System Based On Wireless Sensor Networks

With the progress of society,people's living standards are improved. People now have more attention on the safty of family property and home. People's conception of family residential changes a lot. People not only need houses which is spacious and deluxe, but also need living spaces which is saft and convenient. More and more products fixed people's need can be bought from market. More and more family consider to buy one of these products to prevent something to happen, such as theft, fire and so on. These product can insure family members'safty and property against theft and fire. But we find that these product is not intelligent,many function should be acceded to these product.We design two system to meet ordinary family's need. One system is family security system based on wireless sensor networks. Another system is control system based on wireless sensor networks.Based on the family wireless network security system is mainly for families in the design of the circumstances of the theft. Application of the low cost but is widely used form of PT2262/PT2272 family of wireless sensor networks. on the one hand makes the installation more convenient, on the other hand to protect the family within the original decoration. Users can set up alarm call, when a situation occurred after the police, set up by the host automatically dial the phone, users need not intervene to improve the emergency response rate, make it possible hazards to a minimum. Built-in clock chip, for the host to provide accurate time signal, host to clock chip can automatically deployed. Especially in the evening due to negligence of the owner if the deployment forget the manual, the host will be automatically deployed.Based on the wireless network control system, forming wireless sensor networks by PT2262/PT2272, will probe high-end detectors and low-end organic together. Mainly in the family fire, gas leak, theft, the system can happen in these cases to deal with as soon as possible, making losses to a minimum. For system is flexible, given full consideration to PT2262/PT2272 resources, a family can be deployed in the number of rooms can be reached eight, the detector can be reached Category 4, each detector in a room in the number can reach two . This will fully meet the needs of a family. Detector and the host's address code and data can change the code are, therefore, need only follow a set of rules, you can not only in the case of the original system change detector types, but can also achieve the same kind of detector Replacement.
