Title:
PATTERN GENERATION DEVICE, PATTERN GENERATION METHOD, AND RADIO COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2022185211
Kind Code:
A
Abstract:
To provide a device that when many communication networks for communicating using a frequency hopping method exist in the same area, reduces possibility of collision between their radio waves.SOLUTION: An industrial radio communication system 10 comprises a communications network 14 including a pattern generation device 24 comprising: a random number generation unit that takes a unique number given to a base radio device 18 as a seed to generate a plurality of random numbers; an association unit for associating different random numbers with frequencies of respective channels; and a pattern generation unit that on the basis of numerical values represented by the respective random numbers, determines order of the plurality of random numbers and arranges frequencies corresponding to the random numbers in the same order as that of the random numbers to generate a change pattern.SELECTED DRAWING: Figure 1
