Household security system

Abstract

The invention provides a household security system which comprises a home gateway, sensors and a zigbee wireless transceiver, wherein the zigbee wireless transceiver is used for providing information interchange between the sensors and the home gateway; the home gateway comprises a central processor and further comprises a camera interface for connecting a camera, a UART (Universal Asynchronous Receiver / Transmitter) serial port interface, an Ethernet interface, an SPI (Single Program Initiation) interface, an LCD (Liquid Crystal Display) interface and an I / O (Input / Output) interface which are arranged on the central processor; the central processor comprises a master chip s3c6410 based on an ARM11 framework and a peripheral circuit; the camera interface is a USB (Universal Serial Bus) interface capable of connecting a USB camera; the UART serial port interface is connected to a MC35iGSM module; the I / O interface is connected to a voice alarm; and the sensors comprise a fire detector, an antitheft detector and a gas detector. A complex wiring process for mounting the household security system is omitted, thereby realizing multi-point and remote transmission of security information, promoting safety and reliability as well as hidden performance of the household security system, and lowering the cost.

Description

technical field [0001] The invention belongs to the technical field of wireless network communication control, in particular to the application field of a digital home security system based on zigbee technology. Background technique [0002] After the Ministry of Public Security held the first national criminal technology prevention work conference in Shijiazhuang in 1979, security technology prevention, as a professional field, has experienced more than 20 years of development. The application scope of the security industry is constantly expanding, and the three historical stages of the development of the security industry are summarized, which are mainly characterized by the application of the security industry. From 1979 to 1983, the initial stage. The application range of the security industry is limited, mainly limited to very important and special units and parts. The typical security projects at that time were the Palace Museum project and the monitoring project of ...

AI Technical Summary

Problems solved by technology

The security system is no longer limited to anti-theft, but also anti-robbery, fire prevention, and real-time understanding and resolution of emergencies in the home, so as to realize the intelligence of the home security system. The security systems that appear on the market today are not easy to cause false alarms, or the functions are relatively single, or they use wired connections, which are cumbersome and easy to age.
