【摘要】 本文设计了一种基于GSM网络的安防系统。该系统主要由主控系统(MCU)、前端传感器(振动传感器、角度传感器、加速度传感器、力传感器、声音传感器和图像传感器等)、执行器、电源模块、GSM通信模块以及计算机接口模块等组成。 随着人们生活水平和科技的进步,越来越多的家电产品和高档消费品进入了人们的生活,但随之而来的除了方便人们的生活外也使得家居的安全防范成为一件棘手的问题。而且盗贼的盗窃手段也越来越高明。所有的这一切都呼唤出现一种智能安防系统,既能够监控防范家居的各种安全隐患,也能够起到很好的防盗作用。 本文介绍的基于GSM网络的安防系统正是基于此目的而研制开发的。该系统主要是利用前端传感器采集现场的各种信号,这其中包括各种设备的运行状态信息、环境信息以及各种声音和图像信息。对传感器采集到的信息通过单片机处理提取其中有用的部分,通过一定的决策算法,最终决定是否应该发送报警信息或者执行防范动作。报警信息通过GSM模块以短信息、语音或者其它形式发送到用户的手机终端上。这样用户便可以及时地了解现场的各种信息,用户也可以通过手机短信息的方式,以预先设定好的指令来访问现场各种设备的状态信息或者控制现场设备执行防范动作,从而实现了—种双向的主动和被动相结合的安全防范系统。此外系统的各种参数可以由短信息方式设定,也可以通过系统USB接口即插即用的连接到个人电脑,通过应用软件很方便的设定。 本文设计的基于GSM网络的安防系统,技术先进、应用灵活、扩展性好、使用方便,为家居、车辆等安防系统设计提供了一套切实可行的参考设计。更多还原

【Abstract】 A security and defense system based on GSM is described in this paper. This system consists of main control system (MCU), sensors (vibration sensor, angle sensor, acceleration sensor, force sensor, voice sensor and image sensor), actuator, power module, GSM module, computer interface module and so on.With the development of people’s living standard and technology, more and more electrical home appliances and luxury goods have entered people’s life, but the following one makes the safe precaution of home become the headache besides facilitating people’s life. And the robber’s means of stealing is more and more sophisticated. All all these is it appear one intellectual security and defense system, can is it take precautions against various kinds of potential safety hazards of house to control already to call, can play very good theft-proof function too.A security and defense system based on GSM has been developed just for the purpose mentioned above. This system mainly utilizes various kinds of sensors gathering local signals that include status information of operation of different equipment, environmental information, sound and image information. Through certain decision algorithm, the microcontroller manages and picks up the useful part among the information that has been gathered by sensors, then determine whether it should send warning message or carry out defence action. Warning message will be sent to users’ phones in short message, voice call or other forms by GSM module. In this way users can acquire various kinds of local information in time. Users can also visit local equipment status informations or control it to carry out defence actions by the order set beforehand in short message. Thus a kind of bidirectional security and defense system syncretizing initiativeness and passiveness has been realized. In addition, parameters of the system may be set by short message and application software through USB interface.Security and defense system based on GSM in this paper is advanced, flexible, expansile, easy to use, and can offer a set of feasible reference for the design of such security and defense system as the house, vehicle, etc.更多还原
