<p>PROBLEM TO BE SOLVED: To conduct quickly monitoring jobs macroscopically by receiving a projector power supply automatically on the occurrence of a fault or the like. SOLUTION: In the monitor controller in which a large sized projector 1 is used as a display device and a CPU 2 is used to send a video signal, a signal output module 11 to fetch a power supply on/off signal to the projector 1 is mounted on the CPU 2. Projector power supply ON information is added in advance to an equipment/instrumentation information database and a projector power supply on-output is put out automatically when fault information is received.</p> |
