In these systems, a relay device captures the operating state (fault, normal) of various devices, and the relay device cyclically transmits the operating states of various devices to the failure confirmation device of the central office by a predetermined transmission format. .

This failure confirmation device consists of a communication processing device, a keyboard, and a CR.
It has a display device composed of T etc. and operates as follows.

The communication processing device stores the graphic data of the device in the memory as shown in Table 1 below, and when receiving the failure information of the device, reads the failure graphic data “3” and transmits it to the display device. When the blower is displayed based on the graphic data of the table, the display form is as shown in FIG. Note that FIG. 3A corresponds to a normal figure and is displayed in white, for example. FIG. 3B corresponds to the restoration figure, and is displayed in, for example, the safety color green. FIG. 3C corresponds to a failure confirmation figure and is displayed in a caution color yellow. FIG. 3D corresponds to the failure figure and is displayed in a red warning color.

The display device receiving "3" displays the failure graphic on the screen.
The failure graphic displayed on this screen informs the operator of the equipment failure. Then, when a failure confirmation operation (key input) is performed by the operator, the failure confirmation graphic data "2" is requested to the communication processing device.

In response to this, the communication processor receives the failure confirmation graphic data “2”.
