摘要
利用GPS技术、单片机和射频通信技术,完成了儿童定位和报警电路的设计与制作。本电路解析GPS数据获得儿童的位置、速度信息,SD卡存储轨迹信息,8位ATmega单片机完成距离的计算和逻辑判断,射频收发芯片完成儿童与监护人之间的数据传送,实现两者之间应答式的实时定位监护。
Using MCU and RF IC, a design of children tracking and alarming circuit with GPS technique is presentposition and speed information can be obtained. The information is written in SD card. The information is analyzed by 8 bit ATmega microprocessor, which calculates dised. Through analysis of GPS data and decoding of it, the current tance and makes logical judgment. RF transmitter and receiver allows the real-time positioning and tracking between children and guardian through data transfer.
