Abstract

PURPOSE:To reduce the communication cost without laying plural telephone lines by transmitting gathered data, to which the subaddress designated by a designating means is added, to an optimum data output device through an integrated service digital network ISDN. CONSTITUTION:The designating means designates subaddresses of ISDN basic interface of optimum data output device 29 to 31 (electronic printer 29, high- speed printer 30, and image printer 31) corresponding to data classifications added to gathered data based on data classifications recognized by a data classification recognizing means. A data gathering device 21 transmits gathered data, to which subaddresses designated by the designating means are added, to optimum data output devices 29 to 31 through ISDN 25. Consequently, optimum data output devices corresponding to data classifications of gathered data are dynamically selected without intervention of an operator, and gathered data are transferred and outputted to optimum data output devices. Thus, the increase of the cost is prevented without laying plural telephone lines.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention transmits data collected by a data collection device to a corresponding data output device via an integrated service digital network (hereinafter referred to as ISDN). ■Recommendation 400 regarding output data collection methods, especially C, C, 1, T, and T.
The present invention relates to a data collection method in which the optimal data output device corresponding to the collected data is specified and the data is output using the subaddress of the I5DN basic interface defined in the series.

(Prior Art) FIG. 2 is a block diagram showing an example of a conventional data collection method using a telephone network. In the figure, 1 to 3 are data collection devices connected to the public telephone network 4, and 5 to 7 are data output devices connected to the public telephone network 4. The data collected by the collection devices 1 to 3 are output. Here, each of the data output devices 5 to 7 is, for example, a kanji printer.

Use a high-speed printer or image printer. Further, as the data collection devices 1 to 3, for example, a telemeter, a rain gauge,
Possible options include electric meter reading meters and window machines at each branch.

In the data collection method configured in this way, the data collected by the data collection devices 1 to 3 includes a mixture of different types of data such as kanji data, a large amount of numerical data, and image data. The data output devices 5 to 7 were switched depending on the type of data to be output.

FIG. 3 is a block diagram showing another example of a conventional data collection method using a telephone network. In the figure, 8 to 1θ are data collection devices, 11 is a public telephone network, 12 to 14 are data output devices that output data collected by data collection devices 8 to 10, and 1516 is a data collection device side, data This is a multiplexer on the output device side. The data collection devices 8 - 10 are connected to a public telephone network 11 via a multiplexer 15 and a single telephone line 17 . Further, the data output devices 12 to 14 are connected to one another via a multiplexer 16.
A real telephone line 18 is connected to the public telephone network 11.

The data collection devices 8 to 10 and the data output devices 12 to 14 have a one-to-one correspondence. For example, the data collection device 8 is configured to correspond to the data output device 12, the data collection device 9 is configured to correspond to the data output device 13, and the data collection device 10 is configured to correspond to the data output device 14.

In the data collection method configured in this way, for example, the data collected by the data collection device 8 is sent to the multiplexer 15.
．． Telephone line 17. Public telephone network 11, telephone line 18. The collected data is supplied to the data output device 12 via the multiplexer 16, and the collected data is output from the data output device 12. And by using multiplexers 15 and 16,
Since the data output devices 12 to 14 can be automatically switched, there is no need for an operator to switch the data output devices 12 to 14.

(Problems to be Solved by the Invention) However, the conventional data collection method described above has the following problems.

(1) First, in the conventional data collection method shown in Figure 2, the data collected by data collection devices 1 to 3 includes a mixture of different types of data, such as kanji data, large amounts of numerical data, and image data. However, it was necessary for the operator to switch to the appropriate data output device among the data output devices 5 to 7 depending on the type of data to be output.

Additionally, in order to eliminate the need for operator intervention, it is possible to connect the data collection devices 1 to 3 and the data output devices 5 to 7 in a one-to-one correspondence, but this would require a telephone line for the data output devices. There was a problem with the high cost.

(2) Next, in the conventional data collection method shown in Figure 3,
The operator's work of switching data is not required, and the data output devices 12 to 14 can be connected via the multiplexer 16 using only one telephone line. If the correspondence is one-to-one and each data collection device 8 to 10 is a device that collects multiple types of data, it is not possible to dynamically switch the data output device corresponding to the type of collected data (for example, data collection device 8 cannot be dynamically connected to the data output device 1213).

In view of these conventional problems, an object of the present invention is to dynamically select the most suitable data output device corresponding to the type of collected data without operator intervention, and output the collected data to the most suitable data. It is an object of the present invention to provide a data collection method that can be transferred and output to an output device and that can prevent the increase in cost caused by installing multiple telephone lines as in the past.

(Means for Solving the Problems) The present invention provides data collected by a data collection device such as rsD
In the data collection method, the data collection device is configured to transmit and output the data to a corresponding data output device via the N, and the data collection device includes a data type recognition means for recognizing the type of collected data and outputting the data type; designation means for designating, based on the output of the type recognition means, a sub-address of an I5DN basic interface of an optimal data output device corresponding to the data type to be added to the collected data; The collected data with the subaddress added is transmitted to the optimal data output device via the ISDN.

(Operation) In the data collection device, the data type recognition means recognizes the type of collected data, and the specification means specifies the data type to be added to the collected data based on the data type recognized by the data type recognition means. Specify the sub-address of the I5DN basic interface of the corresponding optimal data output device. The data collecting device transmits the collected data to which the subaddress specified by the specifying means is added to the optimal data output device via ISDN. This makes it possible to dynamically select the optimal data output device corresponding to the data type of the collected data without operator intervention, and transfer and output the collected data to the optimal data output device.

Further, it is possible to prevent an increase in costs without having to install multiple telephone lines as in the past.
