Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0034] The Industrial Internet is a network that is applied in the industrial environment and serves industrial production. With the expansion of the network of industrial equipment, the demand for the Industrial Internet is also increasing. In the industrial Internet, the communication of each device is realized by a bus. Currently, the bus used includes a Controller Area Network (CAN) bus, a Process Field Bus (PROFIBUS) bus, and the like. However, the above-mentioned bus mainly adopts single-carrier technology, ...

Abstract

The invention discloses an OFDM-based data transmission method, device, equipment and storage medium. An OFDM-based data transmission method includes: adopting a discrete mode to carry aperiodic service data, wherein, in the discrete mode, wireless frames are in the same M consecutive OFDM symbols of subcarriers carry service data, and adopt continuous mode to carry periodic control data. According to different data types, it is carried in the wireless frame and the wireless frame is sent. The OFDM-based data transmission method, device, equipment and storage medium disclosed in the present invention are used to realize real-time transmission of multiple concurrent data.

Description

technical field [0001] The embodiments of the present invention relate to network technology, and in particular to an OFDM-based data transmission method, device, device and storage medium. Background technique [0002] In the industrial Internet, the communication of control data is mainly realized by bus. At present, in the industrial Internet, the control bus is a narrowband transmission bus, which adopts single-carrier technology, and data is transmitted based on time slicing and time-sharing. For various types of business data, they are transmitted sequentially according to the priority of the business. [0003] But for multi-service transmission, the current bus transmission mode can easily cause bus congestion. With the expansion of the scale of the industrial Internet and the increasing number of access devices, the current data transmission method of the control bus can no longer meet the high-speed and real-time transmission requirements of data. Contents of th...
