Objective To improve the ability of highly concurrent reading and writing of data transmitted by the Internet of things,a highly concurrent reading and writing system of data transmitted by the Internet of things based on single chip microcomputer was designed in this study.Methods Firstly,the data signal equalization model was constructed,and the data fusion model was established according to the physical node resource consumption,and the impulse response value of the channel was calculated,and the channel equalization control was realized by the random sequence spread spectrum method.Finally,the adjacent frame compensation method was used to measure the highly concurrent reading and writing parameters of the data,and then the error compensation was realized through symbol modulation in the transmission process.On the basis of software design,51 MCU was used to construct the hardware development and design of the highly concurrent reading and writing system for data transmission in the Internet of things.Results The experimental results showed that the stability of the method for the highly concurrent reading and writing of the data transmitted by the Internet of things was always above 0.8,and the transmission error rate was only 0.203%.Conclusion The system in this paper has good stability and low transmission error rate,which effectively improves the ability of highly concurrent reading,writing and control of data transmitted by the Internet of things.
