Abstract

PURPOSE:To deal with statistic data with an existing controller despite the development of a device containing the new statistic data and to be controlled by sending a statistic item name corresponding to an identification symbol and an up-load command of the statistic data to the device to be controlled that transmitted an identification symbol of unmatch when unmatching is secured with the identification symbol. CONSTITUTION:A controller 1 decides whether an identification symbol is included in a statistic data storage table 11 or not and sends a command to a device 4 to be controlled to up-load a statistic item since an identification symbol '000' is not contained in a common data base. Thus the device 4 reads a statistic item name 'X' corresponding to the symbol '000' out of a data storage part 43 and sends it to the controller as a response. The controller 1 stores the name 'X' into the table 11 together with the symbol '000'. Thus the controller 1 can control the new statistic data even if the device 4 contains its own new non-common statistic data. Then the statistic data can be dealt as the common statistic data.

Description

Detailed Description of the Invention Technical Field The present invention relates to a statistical data management system, and more particularly, a control device and a plurality of controlled devices are connected by a communication cable, and each of the control device and the controlled devices connects the communication cable. The present invention relates to a statistical data management method when statistical data is exchanged via the network.

Prior art In a collective terminal device having such a control device, a controlled device that has statistical information that does not exist in the database of the control device cannot exchange data with the control device; It is not compatible with collective terminal equipment, and therefore can only support fixed statistical information.

In the conventional system described above, the control device has a database dedicated to existing controlled devices, so if a controlled device is developed that has statistical data that is not included in this database, the control device has a database that corresponds to the statistical data. The disadvantage is that a new control device must be developed.

Purpose of the Invention Therefore, the present invention was made to solve the drawbacks of the conventional ones, and its purpose is to ensure that even if a controlled device having new statistical data is developed, it can be handled by the existing control device. The objective is to provide a possible statistical data management method.

Composition of the Invention According to the present invention, a control device and a plurality of controlled devices are connected by a communication cable, and statistics are obtained when the control device and each of the controlled devices exchange data via the communication cable. The data management method includes statistical data, a statistical item name indicating a data name of this statistical data, and an identification symbol for identifying this statistical item name, and Each of the control devices includes
Storage means is provided for storing the identification symbol, the statistical item name, and the statistical data, and each of the non-control devices stores the information in its own storage means in response to an identification symbol upload command from the control device. An identification symbol is sent to the control device, and the control device compares the sent identification symbol with the identification symbol stored in its own storage means, and if there is a mismatch, it sends the mismatched identification symbol to the device that sent it. A statistical data management method characterized by controlling a control device to send a statistical item name corresponding to the identification symbol and a statistical data upload command. This will be explained in detail.

FIG. 1 is a system block diagram of an embodiment of the present invention.

The control device 1 is configured to exchange data with a plurality of controlled devices 2 to 4 via a communication cable 5.

The control device 1 stores a common statistical database in the format shown in FIG. 2 in the statistical data storage table 11, and the controlled devices 2 and 3 store statistics in the format shown in FIG. 3 in the statistical data storage units 23 and 33, respectively. It has a database. Furthermore, the controlled device 4 has a statistical database in the format shown in FIG. 4 in the statistical data storage section 43.

As shown in FIG. 2, the statistical database possessed by the control device 1 includes individual statistical data, statistical item names indicating the data names of each of these statistical data, and information for identifying each of these statistical item names. It consists of an identification symbol.

In this embodiment, the controlled device 4 has statistical data as shown in FIG.
It is assumed that the Therefore, the statistical data storage section 43 of the controlled device 4 includes data as shown in FIG. 5 in addition to the data shown in FIG.

That is, the statistical item name X regarding another statistical data Xl different from the common statistical data A-C, and its identification symbol “00
0'' is stored in the statistical data storage section 43 in advance.

Each transmission/reception control unit 12.21, 31.41 has a command and data transmission/reception function, and the control unit 13゜22.32.4
2 has a function of controlling each part. The display section 14 has a function of displaying statistical data, etc., and the memory section 15 has a function of displaying statistical data etc.
A memory for temporarily storing control programs and data.

In the above configuration, first, the control unit 1 and the controlled device 2.3
The data upload sequence between the two will be explained with reference to FIG. When the control unit 1 generates a command to upload an identification symbol from the transmitting/receiving unit 12 via the cable 5, the controlled units 2 and 3 receive this command at the transmitting/receiving unit 21.31, and as a response, the statistical data storage unit 23 Identification symbol “002” stored in .33
"003" is returned to the control device 1.

The control device 1 uses these identification symbols “002”, “00”
31 exists in the statistical data storage table 11. This determination is performed by the control unit 13. In this case, since they exist, a command for uploading the statistical data B1, C1 corresponding to each identification symbol is sent to the controlled device 2.3.

In response to this, the controlled device 2.3 sends statistical data B1, C1 to the control device 1 as a response. Since the control device 1 has already confirmed that the identification symbols “002” and “003” received from the controlled device 2.3 exist in the statistical data storage table 11, the statistical data Bl and C1 are stored in the common statistical database. They will be stored in the portions corresponding to the identification symbols "002" and "003" in FIG. 2, respectively. The contents of this common statistical database are displayed on the display section 14 according to a predetermined format.

Next, the data upload sequence between the control device 1 and the controlled device 4 will be explained with reference to FIG. When the controlled device 4 receives the identification symbol upload command from the control device 1, the identification symbol “002” is retrieved from the database in the statistical data storage unit 43 as a response.
“000” is returned to the control device 1.

The control device 1 uses this identification symbol as the statistical data storage table 1.
1, and for "002", the same procedure as explained in the sequence of FIG. 7 is performed.

Since the identification symbol "000" does not exist in the common statistical database of the statistical data storage table 11, the control device 1 sends a command to the controlled device 4 to upload statistical items.

In response, the controlled device 4 reads the statistical item name "X" corresponding to the identification symbol "000" from the statistical data storage section 43 and sends it to the control device as a response. Control device 1
stores this statistical item name “X” in the statistical data storage table 11 together with the identification symbol “00ku”. Furthermore, a command for uploading statistical data is sent to the controlled device 4.

In response to this, the controlled device 4 returns statistical data X1 from the database (FIG. 4) of the statistical data storage section 43 to the control device 1 as a response. The control device 1 stores this statistical data Xi in the corresponding database section of the statistical data storage table 11 together with the statistical item name and identification symbol name, and similarly displays it on the display section 8.

Effects of the Invention As described above, according to the present invention, a database is configured with identification symbols, statistical items, and statistical data, and the control device uses the identification symbols to manage statistical data in the controlled device. Therefore, even if the controlled device has its own new non-common statistical data, the control device can manage the new statistical data using its identification symbol, so it can be treated as common statistical data. It has the effect of becoming.
