Developing a module-based security system for an intelligent home

The security system in a workplace or home is important to human life. Unlucky events are often caused by the negligence of humans. We have developed a modulebased security system for home automation. The structure of the security system contains many modules. Each module has two types of interface (wireless RF and speech). There are active and passive modules in the security system. The active security module is a smart robot. We have designed many types of smart robot for the security system. The passive security modules include a fire security module, an intruder security module, an environment security module, a gas security module, an AC power security module, and an appliance control module. In the security module, we use multisensor fusion algorithms to decide the exact output. In these modules, we use a two-wire communication method through the wireless RF interface, and a voice alarm for serious events, and transmit the real-time status to the supervised computer. In the smart robot system, we have designed many types of smart robot for the security system. We have designed a general user interface (GUI) for the intelligent security system. The user interface can supervise these modules and the smart robots via the wireless RF device, and supervise the security system via wireless, Internet, and cell phone.
