Abstract

The invention provides a frequency resource and power distribution method and device for a high-speed industrial bus system, electronic equipment and a computer readable medium; the high-speed industrial bus system adopts an OFDM communication mechanism; the method comprises the following steps: dividing a frequency resource into N segments; carrying out frequency resource allocation from the low-frequency band to the high-frequency band, and sequentially allocating the frequency resources to the terminal nodes from the maximum channel attenuation to the minimum channel attenuation. According to the technical scheme of the invention, the method is suitable for different transmission distance scenes, and the transmitting power is as small as possible under the constraint of a given coding modulation mode and transmission capacity.

Description

technical field [0001] The present application relates to the field of industrial control bus communication, in particular, to a method, device, electronic device and computer-readable medium for frequency resource and power allocation of a high-speed industrial bus system. Background technique [0002] The communication rate of the current process industry field bus is mainly low speed. The HART communication rate is 1.2kbps. The communication rate of FFH1 bus and PROFIBUS PA is 31.25kbps. The physical layer of MODBUS RTU and PROFIBUS DP is RS-485, and its communication rate will not exceed 12Mbps. These bus communication technologies, which are widely used in the field of process industry, originated in the 1990s, reflecting the technical level of data communication at that time. However, due to the process industry's own reasons, the development of industrial fieldbus is slow, but it occupies the mainstream position of industrial field communication. Most of the exist...
