摘要
针对传统采集技术以人工操作为主导致数据采集效率较低、时间较长的问题,提出了物联网RFID技术的统计数据采集方法研究。构建物联网技术应用于拟审计算机数据采集影响模型,确定拟审计算机数据采集影响因素。选取Mesh网络结构作为感知网络结构,以ZigBee与GPRS为数据感知中心进行数据通信。根据RFID技术原理,计算不同参考节点到需要采取的信息节点距离,确定信息节点坐标。计算异常数据借助RFID技术扫描的初始时间,设定基础阈值,分析异常数据扫描初始位置,确定异常数据扫描初始时间,由此定位异常数据。确定数据时序,保证统计数据在不同采集设备上采集幅度保持一致性。控制读写数据,对齐统计数据字边界,设计数据采集流程,降低信息传输过程中时延出现的概率,由此完成数据采集。通过实验研究结果可知,该技术最高采集效率为80%,采集512bits数据时间比传统技术快30ms,具有良好采集效果。
Aiming at the problem of low data collection efficiency and long time due to manual operation of traditional collection technology,a research on the statistical data collection method of Internet of Things RFID technology is proposed.Construct a model for the application of the Internet of Things technology to the computer data collection to be reviewed and determine the factors affecting the computer data collection to be reviewed.Select the Mesh network structure as the sensing network structure,and use ZigBee and GPRS as the data sensing center for data communication.According to the principle of RFID technology,calculate the distance between different reference nodes and the information node to be taken,and determine the information node coordinates.Calculate the initial time of the abnormal data scanning with RFID technology,set the basic threshold,analyze the initial position of the abnormal data scanning,determine the initial time of the abnormal data scanning,and locate the abnormal data.Determine the time sequence of the data to ensure that the statistical data is consistent in the acquisition range on different acquisition devices.Control the reading and writing of data,align the word boundaries of statistical data,design the data collection process,reduce the probability of delay in the information transmission process,and thus complete the data collection.The experimental research results show that the highest collection efficiency of this technology is 80%,and the collection time of 512bits data is 30ms faster than the traditional technology,and it has a good collection effect.
