摘　　要：针对无线局域网运行的过程中数据推送存在延迟性以及推送精度较差的问题,需要对无线局域网中数据实时推送系统进行设计。利用当前方法不能有效地实现数据推送的实时性,降低了数据推送的精准度。为此,提出一种基于单片机的无线局域网中数据实时推送系统设计方法。该方法首先进行硬件部分设计,硬件部分主要选用的是SIM900A的推送模块与控制器制成,与串口的终端进行收发数据,以无线局域网为纽带,结合键盘、音频设备和显示器构成,软件部分结合多特征提取算法对数据的提取,以遗忘曲线对用户的兴趣进行分类,将软件与硬件相结合完成对无线局域网中数据实时推送系统设计。实验结果表明,该方法有效地提高数据推送的精度,完成数据实时推送。In the process of wireless LAN operation,the data push has the problem of delay and poor pushaccuracy,which needs to design the real-time push system of data in wireless LAN.The current methodcan not effectively realize the real-time data push,and reduce the accuracy of the data push.In thispaper,a new real-time push system design method based on single chip microcomputer is proposed.Thismethod firstly carries on the hardware design,the hardware part of the main selection is SIM900A pushmodule and controller,and the terminals of the serial port to send and receive data,in wireless local areanetwork(LAN),combined with the keyboard and display,audio equipment,software part combined withmultiple feature extraction algorithm to extract the data,classified by forgetting curve to the user'sinterest,combining software and hardware of wireless local area network(LAN)data in real-timedelivery system design.Experimental results show that this method can effectively improve the accuracyof data push and achieve real-time data push.
