Problems solved by technology

Although these two methods can solve the problem of communication transmission, there are still some problems. For example, in the entire power network, there may only be two nodes in the wired power line carrier communication part. There are path problems, so the wired method is directly abandoned and the wireless me

Embodiment Construction

[0050] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0051] According to the current problems in the Internet of Things communication, a dual-mode solution is proposed. The key feature is that in the Internet of Things communication, the two communication modes share the application layer and protocol stack, and the physical layer is composed of two transmission modes. , Both of these two physical layer transmission modes can send data blocks of the protocol stack. At the same time, the data blocks received in these two physical layer modes are reported to the protocol stack for processing. In the communication process, the protocol stack does not care about which physical layer transmission mode the physical layer uses for transmission, such as figure 1 Shown. The features of the present invention are:

[0052] First: The application layer can set the physical layer preferred transmissio...

Abstract

The invention relates to a physical layer double mode design method of a communication module in the Internet of Things, and belongs to the field of communication of the Internet of Things. In the communication of the Internet of Things, an application layer and a protocol stack part in two communication modes are shared, a physical layer is respectively composed of two communication modes, the two communication modes of the physical layer can send data blocks of the protocol stack. At the same time, the data blocks received by the two physical layer modes are reported to the protocol stack for processing. In a communication process, the protocol stack does not care about the physical layer adopts which physical layer transmission mode for transmission. In a complex Internet of Things communication scene, the two communication modes of the physical layer are adopted to improve the communication ability in the Internet of Things, which is conducive to improving the performance of the Internet of Things.

Description

Technical field [0001] The invention belongs to the communication field of the Internet of Things, and relates to a physical layer dual-mode design method of a communication module in the Internet of Things. Background technique [0002] Power Line Communication (PLC) technology refers to a communication method that uses power lines to transmit data and media signals. The technology is to load the high frequency carrying information on the electric current, and then use the wire to transmit the information-receiving adapter to separate the high frequency from the electric current and transmit it to the computer or phone to realize the information transmission. [0003] The basic principle of power communication is to use modulation technology to modulate user data when sending, load the high frequency carrying information on the current, and then transmit it on the power line; at the receiving end, first pass the filter to modulate the signal Take it out and demodulate it to get t...
