Abstract

PURPOSE:To prevent an operator from approaching to offlimits area by operating the address of the operator from the strength of the receiving signal of many receivers for receiving an electric wave transmitted from a transmitter carried by the operator. CONSTITUTION:The electric wave constantly transmitted from the transmitter 4 carried by the respective operators is received by the many receivers 3 disposed in respective parts in a facility 1 and the address of the respective operators is obtained in an operation by a position discriminating means in a central supervisory device 7 based on the strength of the electric wave received by the respective receivers 3. Then, when the obtained address of the respective operators belongs to the offlimits area, an alarm is generated to a main person through a speech device carried by the operator by an alarm generating means in the central monitor device 7 and the alarm is issued to the vicinity by a speaker 9 simultaneously. Thereby, the operator approaching to the offlimits area by mistake can be immediately retired from the area.
