Abstract:
1. A system comprising multiple monitoring terminals, each monitoring terminal comprising: at least one facility monitor device which monitors a monitor object facility; a storage device which stores information obtained by said at least one facility monitor device; a communication control device which sends and receives information to and from a monitoring apparatus in a central site via communication; and a control device which controls at least said at least one facility monitor device, said storage device, and said communication control device, wherein: in a case that a plurality of monitor terminals are placed in order to monitor a plurality of monitor object facilities, each of said monitor terminals acts as a server relative to the monitoring apparatus acting as a client in setting an initial state, and in establishing a communication with said monitoring apparatus, each of the control device of the plurality of the monitor terminals authenticates by comparing a first communication information being preset and common among the plurality of monitor terminals with a communication information received from said monitoring apparatus, and when these information are coincident the control device establishes the communication; on the basis of the first communication information, the control device changes a state so that the first communication information is changed to a plurality of second communication information, which are different from said first communication information, and respectively in each of the plurality of the monitor terminals, which is different from each other; in a monitor-warning communication after setting of the initial state, the monitor terminals act as client relative to the monitoring apparatus acting as server; each of the control device of the plurality of the monitor terminals transmits each respective second communication information to the monitoring apparatus and receives authentication from the monitoring apparatus and new communication between the monitor terminal and the monitoring apparatus is established; and the monitor terminal transmits a warning data to the monitoring apparatus after establishment of the communication.
