1. An equipment server comprising:
first processing circuitry
to communicate a message in a common data format with plural device servers which communicate a control signal with at least any one device among plural devices moving in a facility; and
to control equipment in the facility based on a received message, wherein
the equipment includes one or more passage restriction barriers which are provided in the facility so as to be capable of restricting passage of the plural devices
when a passing device among the plural devices, the passing device communicating a control signal with a passing device server which is any one of the plural device servers, passes through a place where a target passage restriction barrier is provided, the target passage restriction barrier being one of the one or more passage restriction barriers, the first processing circuitry determines whether or not a passage message is invalid based on the passage message, which is the received message, and outputs an authentication request, when the passage message is determined to be valid, to an access control system which includes the one or more passage restriction barriers.
