Abstract

The invention discloses a communication method, device and system capable of reducing bus interference. Wherein, the method includes: in the process of sending data, adjusting the communication frequency of the bus according to preset rules; after adjusting the communication frequency each time, sending frequency identification data to the target device, and sending the communication frequency to the target device based on the current communication frequency Send target data. Through the present invention, in the process of sending data, the communication frequency of the bus is adjusted according to the preset rules, and after each adjustment of the communication frequency, 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 By dynamically changing the communication frequency of the inter-device bus, the interference energy of the signal is dispersed into multiple frequency spectra, so that the interference energy of each frequency spectrum is reduced, thereby 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...
