出行物品安全已成为当今社会人人外出时必须考虑的一件事,针对这一物品易丢失的问题,文章基于51系列的STC89C52单片机为控制核心;选用通信稳定、功耗低的n RF24L01无线通信模块作为无线发射及接收器件,结合现有电路技术及单片机编程技术,设计了一款便携式距离可调的手提包防盗系统,通过测试,实现了设定范围内声光报警功能,并可进行10米范围内3段距离可调声光报警。 The safety of travel goods has become one of the issues that must be considered in the present society for all to go out. In view of the problem that this article is easy to lose, the article is based on the 51 series STC89C52 microcontroller as the control core. It selects n RF24L01 wireless communication with stable communication and low power consumption Module as a wireless transmitter and receiver devices, combined with existing circuit technology and microcontroller programming technology, designed a portable distance adjustable bag anti-theft system, through the test, to achieve the set range of sound and light alarm, and can be 10 3 meters adjustable range of distance sound and light alarm.
