Abstract

PURPOSE:To judge to which category an alarm belongs by hearing an alarm tone even when a maintenance engineer is separated from a supervisory display panel by detecting a supervisory signal from a station device to be supervised by every category, and issuing different alarm tones at every category. CONSTITUTION:When the supervisory signal from the outside is inputted to the supervisory signal input circuit 3 of the station device 2 to be supervised, the first output signal of the supervisory signal input circuit 3 is inputted to a reception signal processing circuit 4, and is separated to a station alarm 21, a major alarm 22, and a system fault 23. Furthermore, respective alarm signal is inputted to an alarm tone generation circuit 5, and becomes a continuous tone or an intermittent tone of frequency corresponding to respective alarm, and makes a buzzer or a speaker 7 ring via an amplifier circuit 6. Thereby, it is possible to judge to which category out of the station alarm, the major alarm, or the system fault the supervisory signal belongs even when the maintenance engineer is separated from the supervisory display panel.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a remote monitoring system, and in particular, a system comprising a monitoring station device installed at a master station and a plurality of monitored station devices installed at slave stations. This paper is about a remote monitoring method. [Prior art] In the conventional remote monitoring system, when a monitoring signal is received, it is displayed by LED or lamp on the monitoring display panel according to the category of the signal, and at the same time, a single alarm sounds to notify maintenance personnel. It was. [Problems to be Solved by the Invention] In the conventional remote monitoring system described above, the alarm sound is a single sound, so if the maintenance person is far away from the monitoring display panel, the alarm may not be heard even if the alarm sound is heard. There was a problem in that it was not possible to determine which category it belonged to among , major alarms, and system failures.

In addition, in order to monitor multiple slave stations where a monitored station device is installed from a master station where the monitoring station device is installed, the monitoring station device has as many LEDs or lamps for each category of monitoring signal as there are slave stations. As a result, there was a problem in that the monitoring display panel became large and complicated.

An object of the present invention is to enable maintenance personnel to listen to the alarm sound and determine whether the alarm is a station alarm, major alarm, or
It is possible to determine which category it belongs to among alarms and system failures, etc., and there is no need to display monitoring alarms by category in the monitoring station equipment.
The objective is to provide a remote monitoring method that can reduce the number of EDs or lamps. [Means for Solving the Problems] A remote monitoring system of the present invention is a remote monitoring system that includes a monitoring station device and a plurality of monitored station devices, in which the monitoring station device receives information from the monitored station device. The apparatus includes an alarm detecting means for detecting monitoring signals by category, and an alarm sound generating means for emitting a different alarm sound for each category when receiving the monitoring signal.

The remote monitoring system shown in FIG. 1 is composed of a monitoring station device 1 and monitored station devices 2a and 2b. In FIG. 1, when a monitoring signal from the outside is input to the monitoring signal input circuit 3 of the monitored station device 2a, the first output signal of the monitoring signal input circuit 3 is transmitted to the received signal processing circuit (alarm detection means). 4, station alarm (STN ALM) 2 1, major alarm (MAJ ALM) 22. and system failure (SYS
FAL) 23 categories. Furthermore, each alarm signal is inputted to an alarm sound generation circuit (alarm sound generation means) 51, and as shown in FIG. 2 (a), a continuous sound 24 ( Figure 3(a))
, as shown in FIG. 2(b), an intermittent sound 25 of the frequency of the oscillator "2" corresponding to the major alarm 22 (FIG. 3(b))
), and as shown in FIG. 2(C), a continuous sound 26 (FIG. 3(C)) is created by combining the frequencies of oscillator "3" and oscillator r4 corresponding to the system failure 23, and the amplifier circuit 6
The buzzer or slot 7 will sound via the button. Further, an output signal for display is output from the received signal processing circuit 4, and a monitoring display is performed on a display unit 8, which is a monitoring display panel for the monitored station device. Furthermore, the second
The output signal is input from the supervisory signal input circuit 3 to the supervisory signal transmitting circuit 9, and sent to the supervisory signal receiving circuit 10 of the supervisory station device 1 via the transmission path.

The signal of the supervisory signal receiving circuit 10 of the supervisory station device 1 is processed by the received signal processing circuit (alarm detection means) 11 into the station alarm 21, major alarm 22, and system alarm similarly to the received signal processing circuit 4 of the monitored station device 2. It is classified as failure 23. Further, the alarm sound generation circuit (alarm sound generation means) 12 generates a continuous sound 24 of the frequency of the oscillator "1" corresponding to the station alarm 21, and a major alarm 22, similarly to the alarm sound generation circuit 5 of the monitored station device 2. Intermittent tone 25 at the frequency of the corresponding oscillator "2",
A continuous sound 26 is generated by combining the frequencies of the oscillator "1" and the oscillator "2" corresponding to the system failure 23, and the buzzer or the beaker 14 is sounded via the amplifier circuit 13. Further, an output signal for display is output from the received signal processing circuit 11, and a display unit 15 which is a monitoring display panel for the monitoring station device is output.

The conventional display section had a configuration as shown in FIG. 5, but since it is no longer necessary to display alarms by category on the display section 15 of the monitoring station device 1, the display section 15 of the monitoring station device 1 has a configuration for displaying alarms by category as shown in FIG. The number of LEDs or rungs can be reduced, and the monitoring display can be simplified. [Effects of the Invention] As explained above, the present invention enables monitoring signals to be used for station alarms, major alarms, system failures, etc. even when a maintenance person is far away from the monitoring display panel by changing the alarm sound. It has the effect of being able to determine which category it belongs to. In addition, since the monitoring station device does not need to display monitoring signals by category, the number of LEDs or lamps for displaying by category can be reduced, and the monitoring display panel can be simplified. ．．
