Abstract

The invention discloses an Internet of Things method based on signal conversion, and relates to the technical field of Internet of Things. In the data transmission process of the Internet of Things, sent original information is encoded and exchanged to become a signal suitable for being transmitted on a channel, the original information is restored at a receiving end, and discretization processing is carried out on an analog signal in a time domain. According to the method, the redundant information step of removing the information source information is set in the method, the information amount of the digital signals can be effectively reduced, the transmission effectiveness is improved, and meanwhile the steps of conducting pulse code modulation on the signals and conducting linear code processing on the sampling signals are set in the method, so that the accuracy of data transmission is improved. The steps of pulse code modulation on the signals and linear code processing on the sampling signals can effectively reintegrate the signals, so that the influence of other cluttered signals on the converted signals is avoided, and the success rate of signal conversion is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method for the Internet of Things based on signal conversion. Background technique [0002] The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted, and its sound, Various required information such as light, heat, electricity, mechanics, chemistry, biology, and location can be connected through various possible networks to realize the ubiquitous connection between things and things, and between things and people, and realize the intelligence of things and processes Perceive, identify and manage. The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc. It allows all ordinary physical objects that can be independently addressed to form an interconnected network. There are many ways for the signal transmission of the Internet ...
