It has a well-known configuration for management. In the illustrated example, the personal computer 3 is used to transfer the data managed by the controller 3 'of the environmental tester to the LAN. However, the configuration may be such that the environmental tester can be directly connected to the LAN.

In this embodiment, the raw data of the measurement test is stored in the memory managed by the controller 3 'in the environmental tester, and is stored in the memory of the personal computer 3 in the measurement system. As described above, in the test equipment 2, together with the measurement program for controlling the test equipment 2, the data measured by the test equipment is collectively compressed according to a request from the database server 12 and transferred to a specific folder of the database server 12. A siphon program is running.

In this embodiment, a large number of test facilities 2, 2,... Are installed at the same base, and the same L is connected via the HUB 6.
They are connected by an AN, and can exchange data with one database server 12 provided for each base.

The database server 12 stores a transfer program and a management program described later. In the transfer program, first, the order of data transfer requests to the test equipment 2 is set in advance. Then, the database server 12 outputs a data transfer request to the test equipment 2 at the designated time.

When it is confirmed that the requested measurement data has been transferred from the test facility 2 to a predetermined holder of the database server 12, a transfer request is made to the next test facility 2. Here, the data file name transferred from the test equipment 2 is fixed. Therefore, only the latest version of data measured by the test facility 2 remains in the database server 12 after being overwritten, so that the capacity of the memory can be effectively utilized. Terminate the transfer.

Next, the transfer program extracts measurement data for each user based on the compressed data of each test facility 2 transferred to the database server 12, and exemplifies the measurement data for each user as a unit period. Transfer to the Web server 11 once a day at the designated time. That is,
The database server 12 extracts measurement data for each user from the compressed data collected from each test facility 2 and transfers the data as test-unit compressed data to a folder for each user on the Web server 11. Here, a LAN is used for the same base (base A in the illustrated example) from the database server 12 to the Web server 11, and a dedicated line, an intranet, the Internet, or the like is used for a different base (base B in the illustrated example). Communication network can be used.

The measurement data thus stored in the Web server 12 is downloaded from the user's communication terminal 5 through the Internet 4. The user starts the viewer program on the communication terminal 5 as described above,
You can refer to the downloaded data.

The Web server 11 is capable of communicating data with the database servers 12, 12 installed one by one at each base, and is provided with a management program. The management program of the database server 12 is provided. It operates in synchronization with. In the present embodiment, the Web server 11 is connected to the Internet 4 and supports access to a Web page (home page) from the communication terminal 5 of the user.

In the management program, the management data of the user who requested the test is registered and an authentication number (such as a password) is assigned and recorded in a file for the user. The user sets the user to which measurement test the test facility 2 is to be assigned, and makes a schedule reservation for each user.

That is, the operator accesses the Web server 11 or the database server 12 using, for example, the communication terminal 7, starts up the management program, and inputs the contents of the measurement test and the test period. Based on the input data, allocation of the test equipment 2 used for the test and a test schedule are created. In the above embodiment, the data can be input not only to the Web server 11 but also to the database server 12, so that
It is necessary to create unified data.

Therefore, the management program executes replication (data synchronization) between the Web server 11 and the database server 12 between all the sites once every hour, and The management data is unified. The functions of this management program are as follows. (1) The operation status of the registered test equipment can be confirmed. (2) Measurement data of the registered test can be referenced. (3) A test schedule can be reserved. (4) Test management can be performed for each user. (5) The tests at other sites can also be confirmed on the management tool.

The contents displayed on the main screen of the current management program are a list of registered tests. In this embodiment, the test display items include “TEST I
D, "test name", "user name", "test equipment (tester) name", "test number", "last file update date and time", "administrator name", "compressed file name", etc. . On the screen, "By User", "By Exam Name",
The measurement data can be rearranged and displayed for each “TEST ID”, “test equipment”, and “location”.

Further, each registration processing (administrator registration, user registration, test equipment (tester) registration, test registration, schedule reservation), monitor display of test equipment (chamber), button for referring to viewer of measurement data (download button) ) Are arranged (see FIG. 5). In addition, the management program can set a data download time from the test facility 2 and can also transmit a data request by manual operation.

The database server 12 provided at each site and each test facility 2 are connected by a LAN (100 Mbps). In the illustrated example, the test facility 2 compresses all the measurement data and records the data in a memory managed by the test facility.

In the database server 12, the transfer program sets the order of the data transfer request to the test equipment 2 in advance and confirms that the requested data has been transferred from the test equipment 2. A transfer request has been made to Here, the file to be transferred is the same, so the file is overwritten.

When the data transfer from all the test facilities 2 managed by the database server 12 is completed, the transfer program next executes a process for each user set in the management program and the individual measurement test entrusted by the user. From the assignment status to the test equipment, the measurement data for each test equipment in the database server 12 is extracted for each user, and the measurement data is transferred to the folder on the Web server 11 divided for each user.

The user's communication terminal 5 is a personal computer, and allows the user to access a Web page (home page) of the Web server 11 on the trustee side via the Internet 4 by using a Web browser. The Web server 11 allows only a user who has been authenticated via the homepage to download the measurement data corresponding to the user. Then, when the user is authenticated, the reservation status of the schedule and the measurement data can be downloaded to the communication terminal 5 on the user side.

That is, in response to the user's access from the communication terminal 5, the Web server 11 proceeds from the TOP page of the home page to the user-specific data page as shown in FIG. 6, and authenticates the user (FIG. 6 ( a)). After the user authentication, the schedule reservation status for each user is displayed in a Gantt chart (see FIG. 6B). Then, the measurement file corresponding to the user in the user-specific folder can be downloaded (see FIG. 6C).

The downloaded measurement data can be displayed on a display using a viewer program provided in the communication terminal 5. Therefore, in the case of the present embodiment, the user can look at new measurement data every day, and can check the status of the measurement data results every day.
