Abstract

PURPOSE:To allow a monitor center to cope with concentrated calls without requiring a large sized monitor center by adopting the configuration such that a switch is opened when a storage quantity of a received text reaches a setting quantity and the switch is closed when the storage quantity of the received text is less than the setting quantity. CONSTITUTION:When a 1st storage area CH1 only in a memory 26 is able to be stored and a 2nd storage area CH2 or the like is not able to be stored, an incoming switch data memory 30 sets only the 1st storage area CH1 and resets the 2nd storage area CH2 or the like. Thus, an incoming call switch 22a corresponding to the 1st storage area CH1 is closed to receive a call from terminal equipments 1a-1n, while an incoming call switch 22b corresponding to the 2nd storage area CH2 or the like is opened not to receive the call. Thus, the monitor center copes with the concentrated call without increasing the processing capability of an output device and a storage capacity of the memory of the monitor center, that is, without the large sized monitor center.

That is, since it is necessary to increase the size of the output device W5, memory 9, etc., there is a problem that the installation cost of the monitoring center 3 becomes considerably high.

The present invention has been made in view of the actual situation in the prior art, and its purpose is to provide a remote monitoring device that can respond to alerts that are concentrated on a monitoring center without increasing the size of the monitoring center. It's about doing.

[Means for Solving the Problems] In order to achieve this object, the present invention has a monitoring center that monitors a plurality of terminal devices via telephone lines, and receives data transmitted from the terminal devices as received text. In the remote monitoring device, the monitoring center is equipped with a memory for storing received texts, and the monitoring center includes a switch for opening and closing an information transmission path connected to an input side of the memory, and a storage amount of received text to be stored in the memory. A counting means for counting and outputting an output signal when a set amount predetermined according to the storage capacity of the memory is reached, and a switch control section for controlling opening and closing operations of the switch according to the output signal, The switch is opened when the stored amount of received text reaches the set amount, and the switch is closed when the stored amount of received text becomes less than the set amount.

[Operation] Since the present invention is configured as described above, when data transmitted from a terminal device is received at the monitoring center and stored in the memory as received text, the storage amount of the received text is counted by the counting means, An output signal is output when a set amount predetermined according to the storage capacity of the memory is reached.

Next, in response to this output signal, the switch is operated under the control of the switch control section to open the information transmission path connected to the input side of the memory. In this state, there is no line connection between the monitoring center and the terminal device, so even if a notification is output from the terminal device, it will not be received by the terminal device.

Thereafter, when the received text stored in the memory is retrieved and the stored amount becomes less than the set amount, the switch is closed under the control of the switch control unit and the received text is no longer stored in the memory. resume. On the other hand, since the terminal device does not receive the alert while the switch is open as described above, the terminal device issues the alert again after a predetermined period of time.

The data sent from the terminal device is then received at the monitoring center, and the received text is stored in the memory.

As a result, it is possible to respond to alerts that are concentrated on the monitoring center without increasing the processing capacity of the output device of the monitoring center or the storage capacity of the memory, that is, without increasing the size of the monitoring center.

[Example] Hereinafter, an example of the remote monitoring device of the present invention will be described based on the drawings.

The above-mentioned line connection control device 21 includes, as shown in FIG. 24, a text storage management processing section 25 connected to this line connection reception processing section 24, a memory 26 connected to this text storage management processing section 25 and storing received text, and the text storage management processing section 25 described above. a text transmitting section 27 connected to the text transmitting section 27, a transmitting section 28 connected to the text transmitting section 27 and the above-mentioned output device w5, a text management data memory 29 connected to the above text storage management processing section 25, and an incoming call. It includes a switch data memory 3o.

The above-mentioned incoming call switch 22 is controlled by the line connection reception processing section 24 according to the reception status of alarm data outputted from the terminal devices 18 to 1n and the transfer status of the received text to the output device. These incoming call switches 22a-2
2m is open, the notifications output from the terminals W1a to 1n are not received.

When the line connection reception processing section 24 receives alarm data from the terminal devices 1a to 1n via the reception section 23, the text storage management processing section 25 described above stores it in the memory 26 as a received text, and also outputs it to the output device. If there is received text that has not been transferred to W5, the text transmitter 27 is activated and the untransferred received text is transmitted to the output device 5 via the transmitter 28. In addition, this text storage management processing section 25 also processes the memory 2 as described above.
When storing the received text in the memory 26 or when taking out the received text stored in the memory 26 and transferring it to the output device 5, text management data, for example, data indicating the storage location of the received text, is transferred to the output device 5. Data indicating the position of the received text, data on the storage amount of the received text that has not been transferred to the output device 5, etc. are created and stored in the text management data memory 29. The text storage management processing unit 25 is configured to create incoming switch data and store it in the incoming switch data memory 30. The above incoming call switch data is set to be reset when there is no remaining area in the memory 26 that can store the received text, and to be set when there is remaining area in the memory 26 that can store the received text. has been done.

In the above-mentioned memory 26, storage and management of received texts is performed in correspondence with each telephone line 2. For example, if only the first storage area CHI of the memory 26 is storable and the second storage area CH2 etc. are not storable, the incoming switch data memory is set only for the first storage area CHI, and the second storage area CH2 is not storable. 2 storage area CH2, etc. have been reset. Along with this, the incoming call switch 22a corresponding to the first storage area CHI is closed and becomes ready to receive notifications from the terminal devices 18 to 1n, while the incoming call switch 22a corresponding to the second storage area CH2 is closed. The incoming call switch 22b is opened to prevent the above notification from being received.

Note that the above-mentioned incoming calls switches 22a to 22m constitute a switch that opens and closes an information transmission path connected to the input side of this memory 26, and the above-mentioned text storage management processing section 25. The text management data memory 29 and the incoming switch data memory 30 constitute a counting means that counts the amount of stored received text and outputs an output signal when the amount reaches a predetermined amount depending on the storage capacity of the memory 26. , the above line connection reception processing section 24
, the incoming call switch 22 responds to the above-mentioned output signal.
It constitutes a switch control section that controls the opening/closing operation of the sections a to 22m.

In this embodiment, the received text is stored in the memory 26 of the monitoring center 20 according to the processing procedure shown in FIG. That is, for example, the terminal device 1a
When an alarm is issued via the telephone line 2, the line connection reception processing section 24 determines whether there is an incoming bell signal in step 5101, and if there is no incoming bell signal, the process ends. At this time, if it is determined that there is an incoming bell signal, in step 5102, the incoming switch 2
The open/closed states of 2a to 22m are determined.

When it is determined that these incoming call switches 22a to 22m are open, the process ends.

On the other hand, if five of the incoming switches 22a to 22m, for example, the incoming switch 22a, is closed, as step 1 5103, the line connection reception processing section 24 connects to the telephone line 2 via the incoming switch 22a, and the receiving section 23 makes a call. receiving the information data, and then receiving the information data.

In step 5104, the above notification data is stored in the first storage area CHI of the memory 26 as a received text. Then, in step 5105, the text management data described above is updated, and in step jls106, it is determined whether the first storage area CHI of the memory 26 is full of received texts, and if it is not full yet, the process is terminated.

Then, when it is determined that the memory 26 is full of received texts, the incoming switch data stored in the incoming switch data memory 30 is reset, and according to 29,
At step 5107, the line connection reception processing section 24 opens the incoming call switch 22a. Note that the above steps JIIjS] 04 to 5106 are performed by the text storage management processing section 25.

By processing according to the above steps 5101 to 5107, if the received text can be stored in the memory 26, the notification from the terminal devices 18 to 1n is received and stored in the memory 26.
On the other hand, if it is not possible to store the received text in the memory 26, the terminal devices i1a to 1n
You will no longer receive notifications from.

Then, according to the processing procedure shown in FIG.
It is designed to forward incoming text stored in . That is, as step 5201.

Based on the text management data stored in the text management data memory 29, it is determined whether there is any untransferred received text, and if there is no untransferred received text, the process is terminated. On the other hand, when it is determined that there is untransferred received text, the text transmission processing unit 27 is activated in step 5202, and the untransferred received text is transmitted to the output device 5 via the transmission unit 28. In step 5203, the text management data in the text management data memory 29 is updated, and the incoming switch data in the incoming switch data memory 30 is set, and in step 5204, the line connection reception processing section 24 opens the incoming switch 22a. . Note that the above steps 5201 to 5203 are performed by the text storage management processing section 25.

By processing according to steps 711 S 201 to 5207 above, the received text stored in the memory 26 is retrieved and transferred to the output device 5, and then the incoming call switch is opened to receive the notification from the terminal device [1a to 1n]. A new text is received and stored in the memory 26 as a received text.

In the embodiment configured in this way, the processing capacity of the output device 5 of the monitoring center 20 and the storage capacity of the memory 26 are not increased, that is, without increasing the size of the monitoring center 20, the processing power can be concentrated on the monitoring center 20. Able to respond to reports.

In this embodiment, the timing for setting the incoming switch data stored in the incoming switch data memory 30 is set at the time when the received text is transferred to the output device N5, that is, when the received text storage area has room for one text or more. If, instead of having a margin of more than one text, a margin of several texts is provided, the complicated opening and closing operations of the incoming call switches 22a to 22m at the received text storage limit can be prevented. In addition, in the above explanation, incoming call switch 2
Although 2a to 22m are mechanical contacts, instead of using these mechanical contacts, a software switch may be used that connects to the telephone line 11A2 based on incoming call switch data.
