Abstract

PURPOSE:To receive a sent signal even when a manager of a supervised station is absent by using a signal identifying device to identify a sent signal from a supervisory station, operating a line switch based thereupon and connecting a data signal receiver or a sound signal recorder to a line and displaying the result of identification. CONSTITUTION:The bell incoming call signal detector 4 of a supervised station 3 detects a call from a supervisory station 1, uses an automatic hookup mechanism to connect a line between the supervisory station 1 and the supervised station 3 and the outgoing signal from the station 1 is given to a signal identifying device 6. In case of the data, signal, the device 6 operates a line switch 8 to connect a data signal receiver 9 and a subscriber line 2, and in the case of a sound signal, the line switch 8 connects the sound signal recorder 10 and the line 2. Then a signal display device 7 displays the result of identification of the device 6 by, e.g., a lamp. Then even when the manager of the station 3 is absent, both data signal and sound signal can be received.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote monitoring device, and particularly to a remote monitoring device that receives data signals and voice signals from a monitoring station and a monitored station using the same subscriber line.

[Conventional technology]

A conventional remote monitoring system is, for example, disclosed in Japanese Patent Application Laid-Open No. 58-215.
As shown in Publication No. 163, the monitoring station and the monitored station are connected by a subscriber line, and the monitored station has a telephone connected to the subscriber line, and data signals between the monitoring station and the monitored station are connected. A switching device is used to switch between the sound and the voice percentage. In other words, when the bell rings at a monitored station, the administrator immediately picks up the telephone hook and continues the conversation if it is a voice signal, while automatically transmitting data by placing the hook in the case of a data signal. I was receiving it.

[Problem that the invention seeks to solve]

In the above-mentioned remote monitoring system, if the administrator of the monitored station is absent, when the monitoring station sends a voice (No. If the hook is picked up and left in the next state, unnecessary call charges will be added, and the sender will feel uncomfortable because they will not be able to talk even if they pick up the hook for a long time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a remote monitoring device that can receive audio signals and data signals even when the administrator of a monitored station is absent.

[Means for solving problems]

The present invention provides a device that connects a line between the monitoring station and the monitored station when the monitored station detects a bell incoming signal issued by the monitoring station, and whether the signal transmitted from the monitoring station is a data signal or an audio signal. a device for identifying a signal, a device for displaying the results of the identification device, and a device for connecting a line by the identification device to an audio signal recording device in the case of an audio signal and to a data signal receiving device in the case of a data signal. The invention is characterized in that it is equipped with a line switching device.

[For production]

Since the remote monitoring device according to the present invention is configured as described above,
The administrator of the monitored station looks at the display and determines whether the transmitted signal is a data signal or an audio signal. Be able to receive audio signals with a recording device.

[laughing ψ1j] Embodiments of the present invention will be described below with reference to all the drawings.

The monitoring station 1 is connected by a subscriber line 2 to a bell incoming signal detector 4, a line switching device ft8, and a telephone 5 in the monitored station 3. A bell incoming signal detector 4 detects an incoming bell signal from the monitoring station 1, and when there is an incoming bell signal, an automatic hook-up mechanism connects the monitoring station 1 and the signal identification device 6.
Connect the line with. The signal identification device f6 identifies whether the transmission signal from the monitoring station 1 is a data signal or a voice signal, and switches the line switching device 8 accordingly.

Further, the signal display device 7 displays whether the transmission signal from the monitoring station 1 identified by the signal identification device 6 is a data signal or an audio signal.

Next, the operation of this device will be explained.

First, a case will be described in which a transmission signal is sent from the monitoring station 1 when the administrator of the monitored station is absent.

At this time, the bell incoming signal detector 4 of the monitored station 3 detects the call from the monitoring station 1, connects the line between the monitoring station 1 and the monitored station 3 using the automatic hookup mechanism, and transmits the signal from the monitoring station 1. The signal 'lt is transmitted to the signal identification device 6. The signal identification device 6 identifies whether the signal from the monitoring station 1 is a data signal or an audio signal, and if it is a data signal, the line switching device 8
Since the data signal receiving device 11ji9 and the subscriber line 2 are connected by operating the data signal receiving device 9, the data signal from the monitoring station 1 is received by the data signal receiving device 9. On the other hand, when the transmitted signal is a voice signal, the line switching device 8 is operated to connect the voice signal recording device IO and the joining line 2, so that the prayer signal from the monitoring station 1 is received by the voice signal recording device 10. Ru. At this time, the signal display device 7 displays the identification result of the signal identification device 6 using, for example, a lamp.

In this way, even if the administrator of the monitored station 3 is absent, both data signals and audio signals can be received.

Next, a case will be described in which a transmission key signal is sent from the monitoring station 1 when the monitored station 3 has a manager.

In this case, the bell-watching signal detector 4, the signal identification device! 16
By looking at the lamp display on the signal display device 7 displayed via the The user picks up the handset of the telephone set 5, thereby enabling voice communication between the monitoring station 1 and the monitored station 3. Therefore, it is possible to avoid the waste of picking up the handset of the telephone set 5 even though the transmission signal from the monitoring station 1 is a data signal. Further, in the case of an audio signal, since the audio signal recording device (i!110) is connected to the line by the line switching device 8, the content of the conversation between the monitoring station 1 and the monitored station 30 is recorded by the audio signal recording device.

In addition, when transmitting the audio signal from the monitored station 3 to the monitoring station 1,
This can be done using the telephone 5 and via the subscriber line 2.

[Effects of the Invention] As explained above, the present invention identifies a transmission signal from a monitoring station using signal identification IT, operates a line switching device based on the identification, and connects a data signal receiving device or audio signal recording device to the line. At the same time, the above identification results are displayed on the signal display device, so even if the administrator of the monitored station is absent, the transmitted Ig signal can be received, and the administrator can also No need to pick up the phone when needed.
