Abstract

PURPOSE:To make it possible that a high order station monitors power-off of a commercial power source of a low order station, by transmitting a tone signal from a radiotelephony device of the low order station at intervals of a certain time while the commercial power is supplied. CONSTITUTION:When the commercial power source is turned on, a radio-telephony device 2 of the low order station transmits a tone signal fB to a radiotelephony device 1 if the high order station at intervals of a certain time (a) by a tone signal generating circuit 3. The high order station 1 detects the signal fB by a tone signal detecting circuit 4 to reset a timer circuit 5, which is operated by a preliminarily set time, at a time (d). If the commercial power source of the low order station 2 is turned off at a time (e), the timer circuit 5 is not reset because the signal fB is not transmitted. Therefore, low order station commercial power turn-off information (g) is outputted from a monitor information output circuit 6.

In this operation, communication between the second-level station 1 and the lower-level station 2 is performed using a single radio line. In this case, if the power source for the device is commercial power, wireless communication will be impossible if the commercial power is cut off.

きないという欠点があった。Upper station 1. As a power source for the radio telephone equipment in lower station 2, we have DC power supply equipment with a charging function, etc., converting the equipment's electric power to DC power, and when the commercial power supply is cut off, it is possible to secure communication by supplying power from the storage battery of the DC power equipment. I'm used to it. However, depending on various factors such as the equipment at the installation location and the importance of costs, the radio telephone equipment side of lower station 2 may have no choice but to operate with only commercial power input, and in this case, when the commercial power is cut off, Communication becomes impossible and the upper station 1. There was a drawback that it was impossible to determine that the cause of the inability to communicate between the lower stations 2 was due to a commercial power outage.

FIG. 3 is an operation time chart of the monitoring system according to the present invention. Next, to explain this operation, when the commercial power supply is operated manually, the tone signal generating circuit 3 sends a tone signal fB to the upper station radio telephone at time C at fixed time intervals a, as shown in the time chart A. Send to device 1. "The second station 1 detects the tone signal fB of the lower station 2 with the 1.-tone signal detection circuit 4, and resets the timer circuit 5, which operates at a preset time, as shown at time d in the time chart 13. do.

Since the on signal is transmitted, the timer circuit 5 of the upper station 1 is reset, and the output of the commercial power supply cutoff information from the monitoring information output circuit 6 is prohibited. Incidentally, when the upper station 1 and the lower station 2 are talking, the tone signal is sent out after the call ends, so that the tone signal is not mixed in during the communication between the upper station 1 and the lower station 2.
