Abstract

The invention discloses a communication method, device and system capable of reducing bus interference. The method comprises the steps that in the data sending process, adjusting the communication frequency of a bus according to a preset rule; and after the communication frequency is adjusted each time, sending frequency identification data to target equipment, and sending the target data to the target equipment based on the current communication frequency. By means of the invention, the communication frequency of the bus according to a preset rule in the data transmitting process; every timethe communication frequency is adjusted, and the frequency identification data is sent to the target device, and the target data is sent to the target device based on the current communication frequency, thereby dynamically changing the communication frequency of the inter-device bus, dispersing the interference energy of the signal into a plurality of frequency spectrums, reducing the interference energy of each frequency spectrum, and reducing the interference of the communication bus.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, device and system capable of reducing bus interference. Background technique [0002] With the rapid development of electrical equipment, there are more and more communications between electrical equipment. In order to meet the communication needs, the speed of communication lines must be increased. At present, the most direct method is to increase the bus communication frequency to increase the communication rate per unit time. [0003] However, the increase in communication frequency brings about an increase in electromagnetic interference, which is not conducive to EMC (Electromagnetic Compatibility, electromagnetic compatibility) testing and reduction of equipment interference. In order to reduce electromagnetic interference, the purpose of reducing high-order harmonic interference can generally be achieved by delaying the level change of...
