| 摘要 | PURPOSE:To make it possible to confirm the location of a person carring a response signal transmitting slave-device at the remote established place of a master machine, by a method wherein the master machine relays a discrimination signal among ones, which are always transmitted from the slave-devices corresponding to the number of said slave-devices, at every slave-device through a repeater to performs the transmission and reception with each slave-device and each slave-device is constituted so as to be capable of selecting the discrimination sigal transmitted by the master machine and transmitting a response signal. CONSTITUTION:When the location of a worker M1 carrying a slave-device is confirmed, among discrimination signals corresponding to slave-devices 7, 8, 9... always transmitted by a master machine 1, a discrimination signal for the slave-device 7 is received by the slave-device 7 through the repeater 2 positioned at the same floor as the slave- device 7. The slave-device 7 selects that said discrimination signal is one of itself in a selection part at the time of positional detection. When an always inherent response signal is received by the master machine 1 through the repeater 2, the master machine 1 selects the slave-device 7 and the repeater 2 from other ones to detect the positions of both of them and confirms that the worker M1 carrying the slave-device 7 is present on the fifth floor. By this mechanism, the locations of all slave-devices are successively detected and the position of each worker can be confirmed. | ||||||
