Abstract

PURPOSE: To promptly recognize conditions of disasters and prevent secondary disasters by using ordinary television receivers as condition display devices at the occurrence of disasters and providing the functions of preventing secondary disasters according to the kinds of the disasters.
CONSTITUTION: It is assumed now that a fire breaks out. A detector 1 detects this and the information thereof enters a control circuit 6. The circuit 6, upon receiving of this inoformation, causes an alarm sound generator 3 to actuate, alarming the occurrence of a disaster. Arrangement is so made that the picture pattern generated in a video signal generating circuit 7 may be displayed on the television screen by controlling the channel selection circuit and power supply circuit of a television receiver 8. This circuit 7 has stored the sketch map patterns of the supervised areas. The circuit 6 writes the pattern indicating the kind of the disasters in the position showing the disaster location in the picture pattern memory port in the circuit 7. As a result, the symbol or pattern indicating the fire is displayed in the disaster location in superposition with the area sketch map on the televison screen. At the same time, the circuit 6 controls a solenoid valve 9 to stop gas supply and also control a ventilation fan 10 to perform smoke exhaust
