| Summary: | 碩士 === 中華技術學院 === 電子工程研究所碩士班 === 95 === More than fifty percent of Taiwan’s households are left unmanned in the daytime. As the police are short-handed in responding effectively to the rampant thievery and burglary in Taiwan, ZigBee wireless technology provides a tangible safeguard alternative for community and home securities.
In this study, 4 types of sensors, namely entrance control, infrared, smoke and vibration detections, are connected to the surveillance system through ZigBee wireless transmission technology. Once an alarm is triggered at any sensor, a local warning sound will be sent off first. The signal will be transmitted through a wireless module to the computer of the security guard and displayed as a corresponding red light on the monitor with a warning sound such that real-time, low-cost, low-power-consumption alarm feedback can be achieved to fend off crimes.
Contrast to the traditional system, in which signal transmission and connection relies on physical layout of wiring, ZigBee wireless transmission is far more reliable as it is less vulnerable to intentional manipulation. The relocation of the system is also very easy and inexpensive. Remote access and monitoring is possible once the system is integrated with Ethernet. This provides a cost-effective solution of home security for those who need to work in the daytime.
