Abstract
PURPOSE:To perform sure control supervision, by arranging controlled alarm stations connected to the control supervisory station and by storing and transferring information sucessively through respective stations without a repeating station with radio waves of one small-power frequency. CONSTITUTION:The control code is transmitted from supervisory station 10 to adjacent alarm station 1. The control code cnsists of (a) indicating receiving station number 1, (b) indicating controlled station number 3, and (c) indicating siren sounding. Alarm station 1 decides on a basis of station numbers 1 and 3 that the control signal should be transferred to the next station, and the station number is changed to 2 to transfer the control code to alarm station 2 after parity check. The similar operation is repeated, and alarm station 3 decides that the control code is destined for itself, and the siren is sounded. After siren souding, the result signal (A, B, C, and D indicate station number 2, supervisory station number 10, the supervisory result, and parity check respectively) is stored and transferred successively up to supervisory station 10, thus completing communication control. In this constitution, sure control supervision can be executed without a repeating station with radio waves of one small-power frequency.
