The information collected from an information collection unit 13 is sent to the central processing unit 1 together with the address information of the information collection unit 13 with respect to the state change of the supervisory source 14. The central processing unit 1 receives the said information via a modulator-demodulator 3. The operation above is repeated to collect the information from all the information collection units 13.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention monitors various conditions at each installation location or the status of various devices installed at each location using a plurality of terminal devices installed over a wide area. The present invention relates to an information collection device that collects information and collects the information via a communication line.

[Technical background of the invention and its problems] For example, when power is being supplied to demand equipment that is distributed over a wide area, the operating status of the electrical system of each demand equipment and the operating status of the demand equipment can be centrally monitored. It is important to constantly monitor the equipment using monitoring equipment and to be able to take immediate action if a change in status such as a failure occurs in these equipment.

In addition, this is not limited to such power-demanding equipment, but also monitors the operating status of various devices that are distributed over a wide area, such as the opening/closing status of switches, etc., and performs necessary processing in response to changes in the status. The same applies to cases in which various types of information are collected by monitoring the various conditions of each installation location using various devices installed in a distributed manner, and necessary processing is performed according to the analysis results of the collected information.

Information gathering devices that monitor the status of various devices distributed over a wide area and collect information regarding changes in their status generally utilize communication lines. FIG. 6 is a block diagram of such a conventional information gathering device.

In the conventional information collecting device J3 shown in FIG. 6, all information from each part is collected in the central processing unit 1, where each information is processed, and in some cases, the information is displayed or Necessary actions are taken depending on the content of the information. Central processing S! A modem device 3 is connected to the device 1, and the modem device 3 demodulates and demodulates the information collected from each section and supplies it to the central processing device 1, and also sends it out from the central processing device 1 to each section. Information is being modulated. Further, the modem device 3 is connected to a monitoring side exchange 7 via a network control device 5, and is further connected to a plurality of demand equipment side exchanges 9a and 9b via a relay line from this island side converter 7. . The network control device 5 is a desired counterpart to the monitoring side exchange m7 and the demand equipment exchanges 9a and 9b, namely the demand equipment side exchange 9a.

The dial A7 ring operation is performed to send a dial signal to select the desired line (F line 11) connected to the F line 9b.Each demand equipment side exchange 9a.

A plurality of communication lines 11 are connected to 9b, and the plurality of communication lines 11 are controlled by the network control device 5.
One communication line 11 is selected, and the central processing unit 1 is connected to the selected communication line 11 by the modem device 3, network control device 5,
They are connected via the monitoring side receiver 19i machine 7 and the demand equipment side exchanges 11a and 9b. Information units 1 to 13 are connected to each communication line 11, and a monitoring source 14 is connected via this information collection unit 13. Monitoring source 1
Reference numeral 4 monitors the status of, for example, a switch, and information such as changes in status monitored by this monitoring source 14 is temporarily collected by an information collection unit 13.

The information collected by each information collection unit 13 is then transmitted via the communication line 11 to the demand equipment side exchanges 19a, 9b.
, the monitoring side exchange 7, the network control device 5, and the modem device 3, and are collected by the central processing unit 1, so that all information can be monitored by the central processing unit 1.

In the conventional information gathering device configured in this way,
As a method of connecting the central processing unit 1 and each information collecting unit 13 and collecting information from the information collecting unit 13 to the central processing unit 1, there is a method of calling each information collecting unit 13 from the central processing unit 1 and each information. Collection Units 1 to 13
From the central office I! ! ! There is a method in which the device 1 is pushed out.

In the method in which each information collection unit 1 to 13 is made available from the central processing unit 1, each information collection unit 13 to be sequentially called is specified under the control of the central processing unit 1, and the specified information collection unit The dial signal of the communication line 11 to which 13 is connected is sent from the network control device 5 to the monitoring side exchange 7 and the consumer side exchanges 9a and 9b, and the central processing unit 1 is connected to the modem 3, the network control device
It is connected to the communication line 11 to which the specified information collection unit 13 is connected via the monitoring side exchange 7 and the demand equipment side exchanges 9a and 9b. After being connected to the communication line 111 in this way, the central processing unit 1 calls only the specified information collection unit 13 from among the plurality of information collection units 13 connected to this communication line 11, and collects the specified information. The unit 13 collects information from the corresponding monitoring source 14 via the communication line 11, exchange, etc. By sequentially performing such operations on all the information units 1 to 13, the central processing unit 1 collects information from all the information collecting units 13. Nah, 13
Although the figure shows a 1:N configuration in which a plurality (N) of information units 13 are connected to each communication line 11, a 1:1 configuration is also the same.

Furthermore, in the method in which the central processing unit 1 is called from the information collection unit 73, when the information collection unit 13 collects state change information from the monitoring source 14, the information collection unit 13 acquires the communication line 11 to which it is connected. death,
Demand equipment side exchange 19a.

9b and the monitoring side exchange 7, a dial signal corresponding to the telephone number of the central processing unit 1 is sent to call the central processing unit 1. When the central processing unit 1 responds, the information collecting unit 13 is connected to the central processing unit 1 via the communication line 11 and the exchange, and the modulated collected information is transmitted from the information collecting unit 13 via this path, and this information is is demodulated by the modem 3 and collected by the central processing unit r111''c.

In both methods in which information is transmitted as described above, first, in the method in which the central processing unit 1 calls the information collection unit 13, for example, the state change in the monitoring source 14, the switch to be monitored, etc. Changes in the opening/closing status, etc., change at a medium level of about a few degrees of sand and sand, and it is necessary to collect this status change information as soon as possible. One communication line 11 via device side exchanges 19a and 9b
Since it takes about 10 degrees to capture the monitoring source 111, the monitoring source 111 is dispersed over a wide area, and the monitoring source 14 is
However, there is a problem in that it takes a very long time to call one of the information collection units 1 to 13 to collect information, detect and cover changes in status, and that sufficient monitoring cannot be performed.

In addition, in order to call the central processing unit 1 from the information collection units i to 13 in the J method, each information collection unit 13 calls the central processing unit 1 from the information collection units 13 to 3 lines 11. Since it is necessary to provide a network control means built into each information collection unit 13 or externally attached thereto, it is necessary to have a function for capturing the information, drying it, and calling the medium heat treatment device 1. There is a problem that p+jrs is expensive.Furthermore, when information collection units 1 to 13 are connected to the communication line 11 in a 1:N configuration, up to N information collection units]・13 to At the same time, an operation that attempts to capture the communication line 11 of one tree may occur, resulting in the problem that line capture becomes impossible.To solve this problem, a priority circuit for capturing the line 111i is required. There is a problem in that each information collection unit 13 becomes even more expensive.

In addition, in the method in which the central processing unit 1 does not call the information gathering unit 13, when the central processing unit 1 calls the specified information gathering unit 13, if there is no response from the specified information gathering unit 13, the central processing unit 1 The processing device 1 calls the same information collection unit 1-13 several times to increase the reliability of information collection.

However, such a recall operation cannot be performed when the information gathering unit 13 is not connected or when an abnormality occurs in the information gathering unit 13.
13 was disconnected midway through J3, and if this was done without knowing that the information gathering units 1 to 13 were disconnected or removed, it would be a wasteful calling operation, and each information gathering unit 1 to 13 There is a problem in that it takes time to collect information from and detect state changes.

[Object of the Invention] This invention has been made in view of the above, and its purpose is to provide an information collection device that quickly and economically collects information from each terminal device installed at each location. It is about providing.

[Summary of the Invention] In order to achieve the above object, information is collected by monitoring the status of various devices being asked at each location or various conditions at each installation location. The present invention provides a call information collection device that sequentially calls each terminal device via each terminal line to which one or more of the terminal devices are connected and collects information from each terminal device. The central information collecting device connected to the calling information collecting device via a communication line and the calling information collecting device No. 11a call the central information collecting device No. C111′l via the communication line and collect the calling information. The gist is to define the information transmission device that transmits the information collected from each terminal device to the central information collection device.

[Embodiments of the invention] Hereinafter, the present invention will be explained in detail using the drawings.

The information gathering device shown in this embodiment differs from the conventional device shown in FIG. 6 in that a multi-line automatic calling device 15 is connected between the demand equipment side exchanges 9a, 9b and each communication line 11. ing. That is, the central processing unit 1 is connected to the monitoring side exchange 7 and the demand equipment side exchanges 9a and 9b via the modem device 3 and the network control device 5, and the demand equipment side exchanges 9a and 9b are connected to multi-line exchanges 9a and 9b, respectively. It is connected to a plurality of communication lines 11 via an automatic calling device 15. A monitoring source 14 is connected to each communication line 11 via an information collection unit 13.

As shown in FIG. 2, each multi-line automatic calling device 15 includes a calling section 23 that generates a signal to automatically call a designated information collecting unit 13, and a calling section 23 that collects signals and information from this calling section 23. A modulation/demodulation section 25 that converts the Ig code from the unit 13 and a line switching section 27 that receives a designation signal designating the communication line 11 from the calling section 23 and connects the designated communication line 11 to the modulation/demodulation section 25. and a calling unit 21 that receives a calling unit 23 from the calling unit 23 a calling instruction signal for calling the central processing unit 1 from the multi-line automatic calling device 15, and performs calling control.

First, the multi-line automatic calling device 15 periodically calls the monitoring source 14.
In order to monitor the state change in the communication line, the calling unit 23 outputs an instruction signal for sequentially capturing each communication line 11, and the line switching unit 27 is controlled by this instruction signal to control the modem unit 2.
5 and the specified communication line 11 via the line switching unit 27. When a specified communication line 11 is connected to the modulation/demodulation unit 25 via the line switching unit 27, the selected one of the plurality of information collection units 13 connected to this communication line 11 is selected. The specified data stored in the storage unit 29 is The address data of the information collecting unit 13 is transmitted via the communication line 11, and state change information of the corresponding C visual source 14 is collected from the designated information collecting units 1 to 13.

The information gathering operation for each information gathering unit 13 by the multi-line automatic calling device 15 is performed periodically, thereby selecting a monitoring source 14 whose state has changed. As a result, when the multi-line automatic calling device 15 detects any state change, the transmitting section 21 of the multi-line automatic dispensing device 15 sends a dial signal for the telephone number of the central processing unit 1 stored in the two storage sections. From the network control unit 17 to the demand equipment side exchange 9a.

When the central processing unit 1 is connected to the multi-line automatic paging device 15, the information collected from the information collecting unit 13 regarding the state change of the monitoring source 14 is sent to the central processing unit 1 along with the address information of the information collecting unit 1-13. to be transmitted. The central processing unit 1 receives this information via the modem 3. This operation is repeated sequentially to collect information from all information collection units 1 13 .

In the system configured as described above, the multi-line automatic calling device 15 periodically calls each information collection unit 13 to detect a change in the state of the monitoring source 14, and transmits this information to the central processing unit 1. Therefore, as shown in FIG. 6, the information collection operation is faster than that of the conventional device, and the information collection devices 1 to 13 are faster in response to the calling operation from the multi-line automatic calling device 15. The configuration is simple and economical, as all that is required is to send the information. In addition, if the 6th type is called from the information result unit [-13 side, for example, if there are few changes in the status of the monitoring source 14 [), it may be possible to determine whether there is no status change and no information transmission, or if the communication line 11 is defective. Although it may be unclear whether there is no information transmission due to the
5 to 1 call method, it is possible to accurately detect defects or abnormalities in the communication line 11, individual units of the information gathering unit 13, etc., and inform the medium heat treatment device 1 of these. can.

Instead, the central processing unit 1 and each multi-line automatic calling device 15 are connected using a dedicated line 31. This eliminates the need for the organizing tan device 5.17 for selecting an exchange line, and eliminates the need for the time required to select and acquire an exchange line, resulting in a corresponding increase in speed.

FIG. 4 shows another embodiment of the invention.

The information number R device of this embodiment is the medium heat processing device I J

It has a setting device 45 that sets information on whether the information collection unit 13 is installed or not, indicating whether the information collection unit 1-13 is connected to the communication line 43. This prevents unnecessary calls to information collection units 1 to 13 that are not currently available, thereby further increasing speed.

In other words, the automatic collection device 4'1 of this embodiment, as shown in FIG. The stored setting device 45 outputs a calling signal of a predetermined telegram to the information convergence units 1-13 connected to the communication line 43, and also outputs a response signal from the information collecting unit 1-13 to this calling signal. A collection unit 47 that receives the signals and monitors changes in the state of the monitoring source 14, a storage unit 53 connected to the collection unit 47 and storing address data of the information collection unit 13, and a communication line for transmitting the signals of the collection unit 47. a modulation/demodulation section 49 that converts the signal received from the information convergence unit 13 and outputs the signal received from the information convergence unit 13;

In this J: configuration, the collection unit 47 reads out the address data of the information result units 1-13 stored in the storage unit 53 in a predetermined order, and calls the information collection unit 13 with this address data. First, data is loaded into the setting device 45 to check whether the information result unit 1 13 corresponding to the address data is connected to the communication line 43 or not.

As a result of this confirmation, if the specified information collection unit 1-13 corresponding to the address data is connected, the collection unit 47 connects the specified information collection unit 1-13 via the line switching unit 51.
-13 is connected to the specified communication line 43, and connects the four modem units and the specified communication line 43 via the line switching unit 51. Then, a predetermined telegram paging signal is sent to the connected communication N line 43, and information such as state changes in the monitoring source 14 is collected from the designated information collection unit 13.

Furthermore, if it is confirmed that the specified information collection unit 13 is not connected as a result of checking the setting device 45, the collection section 47 selects the specified information collection units 1 to 13.
The next information gathering unit 1 does not perform the calling operation from

It is also possible to read out the code information on whether or not a specified information collection unit 13 is installed, and check whether the designated information collection unit 13 is installed or not.

[Effects of the Invention] As explained above, according to the present invention, the call information collecting device sequentially calls the terminal devices connected to each terminal line to collect information from each terminal device, and collects the collected information. Since the information is collected by transmitting the information from the call information collection device to the central information collection device via the information transmission device, the information is not collected entirely from the central information collection device through the exchange as in the past. When Ril is shortened and speed is increased when collecting information, each terminal device sends out information in response to the paging operation by the paging information collection device. The configuration and functions of the device are simple, small, and economical. Furthermore, installation information setting means is provided to determine whether each terminal device is installed and connected to the line, and only the installed terminal devices are called based on the information from this installation information setting means. Since unnecessary calling operations are not performed for terminal devices that are not installed, the information gathering operation can be speeded up.
