Description

[Detailed description of the invention] This invention is a system that centrally monitors information sent from multiple information sources such as multiple devices to be monitored in one place when they are geographically dispersed. Regarding monitoring equipment.

Conventionally, for centralized monitoring of wired and wireless transmission equipment, telephone exchanges, etc. that are geographically dispersed, or for building management, various information from many points is concentrated in one monitoring room, and the information is Normally, information content is displayed on a display such as a lamp depending on the location and type of information, and an audible sound such as a bell is also used to monitor the occurrence or disappearance of the occurrence. However, it is also common practice for the audible sound to be stopped or the tone to be changed by the operator's operation in preparation for the subsequent generation of information.

In the case of a system like the one described above, when certain information is generated, the supervisor may remotely control the information source or its related equipment by leaving the surveillance room and taking necessary measures. There are many cases where we go to the person's location and take necessary measures. However, it is also very common for other information to be generated while the observer is away. In this case, if there are multiple monitors, it is possible for an empty watcher to take the following measures, but if there is only one watcher at night, etc. When the following information occurs while the observer is away, the observer may be able to detect the occurrence of the information from an audible sound, but cannot know its contents.
Generally, the priority of measures is determined by the content of the information, so the monitor must return to the monitoring room to learn the content of the information. In this case, if the place where the measure is to be taken and the monitoring room are far apart, for example, when taking the measure on the roof of a building, there is an inefficiency in having to go to the monitoring room on the first floor to check the information.

In order to solve this problem, there is a method of distributing displays with the same functions as those in the monitoring room, but
It has been difficult to economically install the display itself, its installation location, information transfer, etc.

An object of the present invention is to provide a monitoring device that eliminates the above-mentioned inefficiency or uneconomical effect and allows all generated information to be easily known even at a location away from the monitoring room.

The monitoring device of the present invention has a means for centrally displaying information sent from a plurality of geographically dispersed monitored information sources in one place, a means for storing the content of the information in advance, and a means for displaying information sent from a plurality of geographically dispersed monitored information sources. It is characterized by comprising means for correspondingly selecting the output of the storing means and transmitting it as an audio signal to a related area.

FIG. 1 shows an embodiment of a monitoring device according to the present invention. In the figure, 11, 12...1n are information transmission lines, and various information is shown as an example in which a ground signal is sent from the information source by space division, but this may also be sent by frequency division or data signals, etc. Of course. Reference numerals 21 to 2n designate information display lamps for receiving the information and displaying necessary information, and reference numeral 3 designates an interface circuit between the lamp and the information transmission line that receives information from the information source and converts it into lamp display information. The OR circuit 41 is for displaying the presence or absence of information with a lamp, and if any information is generated, a total alarm lamp 100, 101, 102...1 of a different system from 21 to 2n is displayed.
Turn on 0k. This lamp 100, 101~
10k is, for example, a large red lamp, and is intended to be lit in several places other than the monitoring room to call attention to it. 43 is an inverter, 44,5
Reference numerals 1 and 52 to 5n are monostable multivibrators, which are circuits that output only one pulse when any of the lamps 21 to 2n is lit. 61 is RS
The flip-flop 62 is a T flip-flop with a clear terminal C, and the RS flip-flop 62 is a T flip-flop with a clear terminal C.
1 is set by the pulse of OR circuit 42 to provide a certain DC output at terminal Q, or reset by the ground provided by sleep keys 110, 111, 112-11k. 120,
121, 122, ~12k are flip-flop 6
This is a bell that emits an audible sound upon receiving the output of 1. 7
receives the drive outputs of the lamps 21 to 2n, scans them, and when there is a lamp lighting output, converts the output number into a read address signal for the next connected audio storage circuit 8. Address circuit 8 is a memory circuit for voice synthesis,
Currently, this circuit can be used in various ways, such as simply storing the audio in analog or digital format, or storing only the parameters that represent the characteristics of the audio and extracting specific parameters by specifying an address to synthesize the audio. There are several methods, but one should be selected in terms of economy, sound quality, etc. 9
is this voice storage circuit and speakers 131, 132
It is an interface circuit with ~13k, and if 8 is an analog type, it is simply an amplifier, and if it is a digital type, it is a digital-to-analog converter and an amplifier,
In the case of the parameter storage type, it is a speech synthesizer and an amplifier. Also 200, 201, 202...20k
2 is a room, and 200 specifically indicates a monitoring room.

Next, the operation with respect to FIG. 1 will be explained.
Now, when earth air is sent to any of the information transmission lines 11 to 1n, the interface circuit 3 operates and lights up the corresponding one of the lamps 21 to 2n.
Necessary information is written and displayed on a display board illuminated by lamps. Also due to this
The total alarm lamps 101 to 10k are turned on through the OR circuit 41. Furthermore, the output pulses of multivibrators 51 to 5n are output to OR gate 4.
2, the flip-flop 61 is set, and the bells 120-12k are rung. Lamp 21-2
The supervisor (assuming that the supervisor is present in the monitoring room at this time), who has learned the content of the occurrence information from the display accompanying the lighting of n, presses the bounce key 110 to stop the ringing of the bell. This operation of the electric key 110 resets the flip-flop 61 and at the same time sets the T-flip-flop 62 to activate the information scanning/addressing circuit 7, which starts scanning information. As a result, when it is known that a lighting output is being given to one of the lamps 21 to 2n, the lamp number is converted into a necessary read address signal and sent to the memory circuit 8. If you write the same information as that displayed by ~2n, it will be read out and broadcast from the speakers in places other than the monitoring room, such as ``Nanakai Kuchiyoushitsu Denatsu Ijiyouteika.'' However, there is no need to install a speaker in the monitoring room, as information can be obtained through a lamp display. If measures are taken to prevent such broadcasts and the source of information disappears, lamps 21 to 21 will be released.
Since the monostable multivibrator 44 applies a pulse to the clear terminal of the T flip-flop 62 at the same time as the lit ones among the 2n and the total alarm lamps 100 to 10k go out,
The T flip-flop is reset and the scanning and addressing circuitry ceases operation, thus stopping audio broadcasting. Furthermore, if it is desired to stop only the audio broadcast, by pressing the telephone key 110 again, the T flip-flop is reset and the audio broadcast is stopped.

Next, we will discuss a case where the supervisor is away from the surveillance room due to the occurrence of certain information. A maintenance worker who confirms the occurrence of certain information presses the telephone key 110 in the monitoring room to stop the bell ringing, and if necessary, presses the telephone key 110 again to stop the broadcast of the information from the speaker. I left the observation room to take measures against him. Now, assume that this destination is room 20i. In this case, total alarm lamp 100
~10k is lit, but the bell has stopped ringing. Suppose that other information is generated while the supervisor is on his way to the room 20i or while working in the room 20i in this state. At this time, a set trigger is applied from the OR circuit 42 to the RS flip-flop 61, so that all the bells 120 to 12k start ringing again. The observer who knows this will find the nearest bounce electric key 11i or 11x (but 1xk)
When you go to the button and press it first, the RS flip-flop 61 will be reset and the bell will stop ringing.
At the same time, the T flip-flop 62 is set, so the information scanning/addressing circuit 7 starts operating, and all the information displayed on the lamps 21-2n is broadcast through the speakers. By listening to this, the supervisor can immediately learn about the content of newly generated information, so there is no need to return to the monitoring room and look at the lamp display every time new information occurs.
Able to make correct decisions instantly. In addition, if the supervisor wants to stop information being broadcast from the speaker, he/she can use the bounce key 11i or 11x.
By pressing again, the T flip-flop 62 is reset and the broadcast is stopped.

Furthermore, even if information is generated three or four times, the overall operation is exactly the same as in the above case.

As described above, according to the present invention, in a monitoring device that centrally monitors a large amount of information from geographically dispersed points, when multiple pieces of information occur continuously, it is possible to monitor the information without returning to the monitoring room each time. Since the information content can be known at any location within the relevant area, action can be taken effectively.

Since voice transmission is used to transfer information within the relevant area, the information transfer line and terminals are extremely simple and inexpensive, requiring only one metallic line and a speaker.

The audio-related circuits 7, 8, 9, etc. in FIG. 1 have recently made rapid progress in audio synthesis, and have been made into LSIs, lower in price, and smaller in size, and their cost share in the entire system is extremely small.

It has the following effects.
