WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, AND CONTROL STATION

The present invention provides a wireless communication system that has high reliability. An abnormality detection system for wireless communication in a control system composed of a control station and a plurality of mobile vehicles which are connected to the control station is constituted. The plurality of mobile vehicles or a stationary wireless station connected to the plurality of mobile vehicles by wireless communication periodically measure position information and wireless communication quality information that indicates the quality of wireless communication and report the measurement results to the control station. The control station groups the measurement results reported from the plurality of mobile vehicles that belong to a first time range, on the basis of the position information and learns the distribution of the wireless communication quality information for each of the grouped positions. The control station further acquires the measurement results reported from the plurality of mobile vehicles that belong to a second time range, which is separate from the first time range, and derives the abundance ratio of an outlier in the measurement results belonging to the second time range, using the distribution of wireless communication quality information per learned position range.
