基于GPS双围栏的学校自动考勤系统

摘要

Based on GPS dual fence a school automatic attendance system?was designed. Compared with the system based on RFID and ZigBee, the algorithm was more accurate and reliable. And at the same time since today’s students use the phone with a GPS module, the server also needs to increase the signal receiving device. It is simple to build deployment for the system, for client data server uses IOCP parallel processing technology. Systems running instances showed that the system had good results.%给出一种基于GPS双围栏的学校自动考勤系统的设计方法。客户端App程序可通过Service服务调用GPS模块来获取终端当前地理位置，并结合双GPS围栏考勤算法得出某个学生的校外或校内状态，进而得出该学生当前是进校还是离校。运行结果表明，相比于基于超高频RFID考勤技术，基于GPS双围栏技术考勤算法更准确、可靠。
