基于NB-IoT的多道并行程序数据召测模型研究

Research on multichannel parallel program data call and test model based on NB⁃IoT

传统的多道并行程序数据召测模型对于病毒的抵御能力较差,导致安全系数较低。为此,基于NB-IoT研究了一种新的多道并行程序数据召测模型。首先分析NB-IoT技术的实现机制,并结合无线网络确定传输机制,引入5个不同的运行线程,与节点匹配包并行服务。同时,利用NB-IoT技术对每个进程进行隐形缓存,缓解计算机处理器的存储空间。多道并行程序可以直接通过共享内存间的数据拷贝来实现,因此线程间的数据通信效率很高,且可以有效地避免网络通信带来的延迟。基于此,利用基于线程的编程方式更好地发挥数据召测的性能,通过初始运行、程序操作、确定程序数据格式、召测信息输出完成召测。实验结果表明,该模型能够有效提高病毒抵御能力,增强安全系数。

The traditional multichannel parallel program data call and test model has poor resistance to virus,which leads to low security factor.Therefore,a new data call and test model of multichannel parallel program is studied based on NB⁃IoT(Narrow Band Internet of Things).The implementation mechanism of NB⁃IoT technology is analyzed,and the transmission mechanism is determined in combination with wireless network.5 different running threads are adopted to make paralleled service together with node matching packets.At the same time,the NB⁃IoT technology is used to carry out invisible cache for each course to remit the burden of the storage space of the computer processor.Multichannel parallel programs can be implemented directly by copying the data in shared memory,so the data communication between threads becomes very efficient and the delay caused by network communication can be effectively avoided.On the basis of this,the thread⁃based programming method is used to give better play to the performance of data call and test,and the call and test process is completed by initial run,program operation,determination of program data format and call and test information output.The experimental results show that the model can effectively improve the ability of resistance to virus and enhance the safety factor.
