Kind Code:
B2
Abstract:
To provide a tunnel disaster prevention system allowing an operator to simply and easily identify and understand in what kind of state a signal line is without viewing a content of predetermined information relating to a current flowing in the signal line when displaying the predetermined information relating to the current flowing in the signal line.SOLUTION: A control unit 40 provided in a disaster prevention reception board 10 as a part of a tunnel disaster prevention system measures a current value flowing in a signal line and determines a current value abnormality as an abnormality of the current flowing in the signal line on the basis of the current value measured. A sub-monitor device 46 as a display unit displays predetermined information (history of the measurement result, and the like) relating to the current flowing in the signal line in an identifiable manner (color arrangement, or the like depending on a state of the signal line) according to the state of the signal line (for example, a current value abnormality, a line failure state, a state during a line test, a fire state, or the like).SELECTED DRAWING: Figure 4
