JPS6488798A - Group supervising device - Google Patents

Abstract

PURPOSE:To easily discriminate the leaving of a constituting member and to facilitate the supervising of a group by discriminating a slave machine, whose output level becomes at a set value or below, among the slave machine to respectively output the signal radio wave of a different code with a master machine and warning it. CONSTITUTION:Respective slave machines 100 are successively connected to a master machine 10, the difference codes are successively inputted by a setting device 12, and the signal radio waves of the different codes are outputted. On the other hand, a controller 26 of the master machine 10 discriminates corresponding frequencies Am and Bl from codes (m and l) stored in a memory 16, and designates local oscillating frequencies to a tuner 24 so as to continuously select the frequencies Am and Bl at every (t) time. The controller 26 compares the output level of the tuner 24 with the fixed value set in a selector 28, and when the value is at the set level or below, the discriminator 28 warns the concerned slave machine 100 through an alarm device such as a buzzer 30. Thus, a superviser can easily discriminate the leaving constituting member.
