Abstract


With the development of Chinese social economy, people long to live in a more comfortable and warm residence. Meanwhile, they hope to live in a safe environment. Therefore, the widespread application of the intelligent system of residential community gradually becomes a kind of new social requirement.This thesis introduces a kind of flexible, convenient, and reliable intelligent alarm system in residence community, which can monitor and give an alarm through the network automatically. Automatic monitor indicates that various multi-sensors can automatically monitor various imitation signals (hot ultra red signal of human body, temperature, smoke-thickness, and harmful gas density, etc.)of various safe affairs in the community, and the application of multiple transducer strengthen the reliability of system. Automatic alarm through the network indicates that through LAN in residence community and TCP/IP , the system can send helping signal to community center. The whole system consists of three parts: sensor、safeguard terminal and community safeguard host. Detecting safe affairs, multi-sensors will output the number of power switch of alarm signal. After coding it will send to household core by the way of wireless, and then the safeguard terminal will control network communication interface automatically, transporting the message to the community safeguard host , so that relevant security guard can rapidly intervene the scene and handle it appropriately according to the type and position of affairs. Meanwhile, the safeguard host of community center will record information for consulting.The sensors of this system and safeguard terminal adopt the way of wireless to send data. It overcomes the weak points that traditional wired line paves difficultly, and once the sensor fixed, it cannot be easy to move. Encoding wireless communicating way resolves the problem that the wireless signals between launching and receiving module of the system interference each other and the problem of partnership. It only needs to set different address codes through DIP switch when using. Automatic alarm gets help from LAN established system in the community, sending affairs information back to community center, which treats TCP/IP. It doesn’t need increase extra communicative circuit, which realizes low cost and commonality. The system designed by considering, and the standard interface makes the whole system easy to expand.The system designs from both hardware and software and strengthens the ability to interfere. This system is practical and reliable, and its function is various and flexible. It can be widely used in residence public community.
