A kind of Internet of things data transmission correction equipment

Abstract

The invention discloses Internet of Things data transmission correction equipment. The Internet of Things data transmission correction equipment includes a frequency acquisition circuit, a frequency division feedback circuit and an operational amplifier output circuit, wherein the frequency acquisition circuit acquires data signal frequency when the Internet of Things equipment works; The frequency division feedback circuit uses an inductor L1 and capacitors C4 to C6 to form a frequency division circuit for signal frequency division. one path of the frequency-divided signal uses a switch circuit composed of a triode Q2 and the triode Q3 to detects abnormal signals. in the second path, a power supply + 10V and a variable resistor RW2 are used for compensating signals; the last two paths ofsignals are input into an operational amplifier AR1 together; meanwhile, the operational amplifier AR3 and the triode Q5 feed back an output signal of the operational amplifier AR1 to the base electrode of the triode Q3; A switch circuit signal conduction value composed of the triode Q2 and the triode Q3 is adjusted, an output signal of the operational amplifier AR1 is output after in-phase amplification is conducted on the output signal of the operational amplifier AR1 through the operational amplifier output circuit, the Internet of Things data signal frequency can be converted into a compensation signal of a data signal of Internet of Things data equipment, and meanwhile the signal is automatically calibrated.

Description

technical field [0001] The invention relates to the technical field of signal calibration, in particular to an Internet of Things data transmission calibration device. Background technique [0002] The Internet of Things refers to the integration of information space and physical space, that is, the fusion of virtual and reality, digitizing and networking all objects and events, and realizing information interaction between people and people, people and things, and things and things. Realize automatic identification of items, monitoring and positioning and remote management. The Internet of Things is based on the existing Internet and various proprietary networks, and transmits various data collected and summarized through the perception layer to realize real-time data transmission and ensure data security. At the same time, in order to make the data transmission of the Internet of Things more accurate, it needs Networked data transmission and correction equipment, however,...

The Internet of Things is based on the existing Internet and various proprietary networks, and transmits various data collected and summarized through the perception layer to realize real-time data transmission and ensure data security. At the same time, in order to make the data transmission of the Internet of Things more accurate, it needs Networked data transmission and correction equipment, however, in practice, when the Internet of Things data transmission and correction equipment is used, there will often be signal attenuation during transmission, and when the signal passes through a strong magnetic field during transmission, there will be signal anomalies, resulting in the Internet of Things Data transfer correction equipment not working well
