Abstract

PURPOSE:To enable data collected at each terminal to be accessed by another terminal by sending the data to a realized table when taking out the data with the address of the data storage part of its own terminal, and sending and outputting the data taken out from the data taken out from the data storage part to the realized table of a call terminal when receiving a command from another terminal. CONSTITUTION:Each terminal is equipped with the storage part 1 of the command, the data storage part 2, the realized table 3 storing an address corresponding to each command and the telephone number of another terminal, and a telephone directory 4 which sends the command to another terminal when the telephone number of another terminal is designated by the realized table 3. When the realized table 3 takes out the data with the address of the data storage part 2 of its own terminal corresponding to the command, the data is sent to the realized table 3. Also, when the designation of the command is received from another terminal, the data taken out from the data storage part 2 is outputted by sending to the realized table 3 of the call terminal with the command of its own terminal corresponding to the command. Thereby, it is possible to automatically make access the data collected with each terminal from another terminal.

Description

[Detailed Description of the Invention] [Summary] Regarding a method for accessing data collected on one terminal from another terminal, a method is realized in which data collected on each terminal can be automatically accessed on other terminals. For the purpose of this, each terminal has a storage section for a specified command, a data storage section, and an actualization table that stores the address of the data storage section of the own terminal or the telephone number of another terminal corresponding to each command, a telephone directory that sends a command to the other terminal by automatic dialing when the telephone number of another terminal is specified by the realization table, and the realization table is a data storage section of the own terminal corresponding to the command. When data is retrieved from the address, the data is sent to the actualization table and output, and when a command is received from another terminal, the data retrieved from the data storage unit in response to the command is actualized on the calling terminal. Configure it to send to a table for output.

[Industrial application field]

The present invention relates to an inter-terminal data access method, and more particularly to a method for accessing data collected by one terminal from another terminal.

In the recent information society, it is required to be able to obtain necessary information no matter where one is, and it is necessary to be able to easily obtain data collected on one terminal on another terminal.

[Conventional technology]

For example, if a person in Tokyo wants to know the humidity in a room in Osaka, the conventional methods are: 1) The person in Tokyo requests the person in Osaka to transfer the data, and 2) The person in Oban sends the data. , the requested data is transferred to the requester in Tokyo, and 3) the person in Tokyo receives the transferred data and uses it for the specified purpose.

[Problem to be solved by the invention]

Conventional methods like this have the problem that each step has to be done manually, which makes the process cumbersome, takes time to access the data, and the probability of receiving accurate data is low. .

Therefore, it is an object of the present invention to realize a system in which data collected by each terminal can be automatically accessed by other terminals.

[Means and operations for solving the problems] In order to solve the above problems, the terminal-to-terminal data access method according to the present invention is such that each terminal can perform command designation (a) as shown in principle in FIG. A storage section 1 for the command specified by , a data storage section 2, and an actualization table 3 that stores the address (C) of the data storage section 2 of the own terminal or the telephone number of the other terminal corresponding to each command (b). and a telephone directory 4 that sends the command (a) to the other terminal by automatic dialing (e) when the telephone number of another terminal is specified (d) by the actualization table 3.

When the actualization table 3 retrieves data using the address (C) of the data storage section 2 of its own terminal corresponding to the command, etc., it sends the data to the actualization table 3 and outputs it (i). Specifying commands from the terminal (
f) When receiving the command (f), the own terminal's command corresponding to the command (f) (by the instant) sends the data (c) retrieved from the data storage unit 2 to the realization table 3 of the calling terminal and outputs (i). Occur.

In this way, by preparing a realization table of the same format on each terminal, data at a remote location can be easily and quickly accessed.

〔Example〕

FIG. 2 schematically shows an embodiment of the terminal-to-terminal data access method according to the present invention shown in FIG.
md2. cmd3. - is stored in the data storage section 2.
For example, the temperature 25°C detected by the thermometer 10 is stored at address 1000 as data, and the actualization table 3 is as shown in FIG.
md2, cmd3. ..., respectively, the address of the data storage section 2 of the own terminal or the number No. B of the other terminal (
In the case of a terminal, the telephone directory 4 is composed of a data storage location for storing the number of terminal B) and an extraction data storage location for storing the data retrieved from the data storage section 2. It has a function that automatically dials the corresponding phone number when it receives a terminal number.

An outline of the operation of such an embodiment is shown in FIGS. 4 and 5, and will be described below with reference to these.

First, when terminal A in Tokyo wants to access the temperature of terminal B in Osaka, it specifies the command necessary for the access (step S1).

As a result, the command storage unit 1 of the terminal A sends the specified command to the actualization table 3.

Then, the actualization table 3 refers to this command (step S2) and specifies the address or terminal number of the data storage location (step S3).

At this time, for example, if the command is cmd 1, step
As a result of checking in block S3, it is found that the address of the data storage section 2 of the own terminal, that is, address 1000, is specified, so the "temperature 25°CJ" at address 1000 is extracted and the extracted data is stored in the actualization table 3. The location is set (step S4).

After this, the data in the extraction data storage location of the actualization table 3 is output (step S8).

Furthermore, if the specified command is cmd 2, the data storage location is specified as the number N0-B of terminal B (FIG. 5TI), so this terminal number No. , the telephone directory 4 specifies the telephone number (T2) corresponding to this terminal number and connects the terminals A-B by automatic dialing (step S5).
).

When the terminal is connected to terminal B, the above specified command cmd 2 is transferred from terminal A to terminal B, so terminal B transfers the address 2000 of the data storage unit 2 of its own terminal corresponding to this command cmd2. Since the address (T3) is specified, the data of this address, ie "Humidity 78%
J is extracted and set in the extraction data storage location of the actualization table 3 of terminal B (step S6).

Then, in the realization table 3 of terminal B, this data [humidity 78%] is immediately transferred to terminal A via the currently connected telephone line.

Terminal A stores the transferred data "humidity 78%" in the extraction data storage location of command cmd 2 of actualization table 3 (step S7).

After this, the retrieved data is output in the same way as the retrieved data of the own terminal (step S8).

In this way, terminal A in Tokyo can immediately access the humidity at terminal B in Osaka.

〔Effect of the invention〕

As explained above, according to the terminal-to-terminal data access method according to the present invention, each terminal has an actualization table that stores telephone numbers of other terminals corresponding to each specified command, and this actualization table When the phone number of another terminal is specified, the command is sent to the other terminal by automatic dialing using the telephone directory, and when a command is received from another terminal, the data retrieved from that terminal is called in response to the command. Since the configuration is configured to send and output to the actualization table of the terminal, you can easily obtain data existing on other terminals in the same way as when obtaining data existing on your own terminal, without worrying about the location. The data access environment will be prepared.
