Description
Technical Field
The invention relates to the field of signal transmission, in particular to a data transmission signal detection system and method based on a block chain and the Internet of things.
Background
The transmission signal is short for a signal suitable for transmission, and includes an analog transmission signal and a digital transmission signal. The transmission signal is a short name of a signal suitable for transmission, and includes an analog signal and a digital signal. Analog signal transmission: transmission means for transmitting information in analog signals in a transmission medium. Analog transmission is a transmission without regard to its content, and is a way of conducting energy, which must be lost during transmission, and whose signal strength is amplified by an amplifier. In long-distance transmission, a stage is needed to amplify the energy, but the noise increases along with the energy, so-called distortion. Digital signal transmission: transmission means for transmitting information in a transmission medium as a digital signal. The digital transmission also needs to amplify signals in the transmission process, and the digital signals are simply recombined and regenerated by utilizing a threshold voltage formed by a circuit to generate new signals which completely eliminate attenuation or distortion.
The transmission signals can be divided into the following four types of transmission: analog data is transmitted in analog signals: traditional telephone systems, which employ hierarchical switching; the long-distance trunk line adopts a frequency division multiplexing transmission mode, namely carrier telephone. Digital data is transmitted in analog signals: for digital transmission in an analog channel, the digital signal must first be converted to an analog signal. The solution is as follows: the positive (remaining) string analog signal of a certain frequency is selected as a carrier signal to carry the digital signal to be transmitted. The specific implementation method comprises the following steps: modulation and demodulation. Analog data is transmitted as digital signals: the sending end converts the analog signal into a digital signal through a decoder, and then the receiving end restores the received digital signal into the analog signal through the decoder. The digital data is transmitted as digital signals: data is encoded to improve the efficiency of data transmission and realize the signal synchronization of both communication parties.
At present, in the process of network model transmission, signal quality difference between a signal sender and a signal receiver can cause signal interruption, so that the signal receiver cannot receive signals, when the transmission signal quality is poor, a network can select a transmission channel according to the nearest distance to resend or resend after waiting for manual maintenance.
