迷你智能蓝牙防丢报警系统设计.pdfVIP

摘 要 本文设计了一种基于单片机STC89C52的迷你智能蓝牙防丢报警系统设计方案 ，由LCD屏显电路、GPS定位电路、蓝牙4.0高速通信电路、按键电路、电源电路 、蜂鸣器报警电路、单片机主控电路共同搭建而成。当主机与从机蓝牙模块断开 连接时，蜂鸣器报警电路会进行工作，发出提示声来提示用户可能遗忘或丢失自 己的物件，并且从机GPS模块会实时与卫星通信，通过接收卫星数据传输到单片 机，单片机会把通过GPS接收到的数据显示在LCD屏幕。本设计系统对用户出现可 能遗忘的小物件或者儿童丢失等情况都有着极为重要的作用，有着极高的市场价 值。该系统优点是精确、高性价比、实用、清晰、灵活。 关键词 STC89C52单片机 蓝牙4.0 防丢 GPS定位 Abstract ： This paper designs a mini intelligent Bluetooth anti-loss alarm system based on STC89C52, which is composed of LCD screen display circuit, GPS positioning circuit, Bluetooth 4.0 high-speed communication circuit, key circuit, power supply circuit, buzzer alarm circuit and MCU main control circuit. When the host is disconnected from the slave Bluetooth module, the buzzer alarm circuit will work and send out a reminder to remind users that they may forget or lose their objects. The slave GPS module will communicate with the satellite in real time. By receiving satellite data transmission to the MCU, the MCU will display the data received through GPS on the LCD screen. This design system plays an extremely important role in the occurrence of small items that may be forgotten by users or the loss of children, and has a very high market value. The advantages of this system are accuracy, high cost performance, practicability, I clarity and flexibility.
