The database server 12, as shown in FIG.
Data is exchangeable with a plurality of test facilities 2, 2, 2,... Provided at the same base (for example, the first basement floor) and connected to a local area network (LAN).

The test equipment 2 includes, for example, environmental test devices (chambers) such as a high-temperature test, a low-temperature test, a constant-temperature and constant-humidity test, a temperature cycle test, a thermal shock test, a HAST test, and a condensation cycle test, migration evaluation, and insulation characteristics. Life tests such as evaluation, bonding reliability evaluation, impedance characteristics evaluation, secondary battery characteristics evaluation, semiconductor reliability evaluation, and other electrical characteristics evaluations, surface observation, cross-section observation, scanning electron microscope, transmission electron microscope, X Various measurement systems that perform analysis and analysis such as X-ray microanalysis and gas chromatography are used. In the test equipment 2, in the environmental tester, a built-in computer-configured controller 3 'controls measurement and manages measurement data, and in the measurement system, a personal computer 3 constituting the controller controls measurement and controls measurement data. 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, the first basement floor (same place)
Has a large number of test facilities 2, 2,.
It is connected to a LAN located on the first basement floor via B6, and a database server 12 similarly connected to the LAN is installed to exchange data with each test facility 2.

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.

In this embodiment, the Web servers 11 are installed in different places (management room on the fourth floor) in the same base. Here, a LAN provided in the same base is used from the database server 12 to the Web server 11. However, as shown in FIG. 3, when the Web server 11 and the database server 12 are located at different bases, they can be connected using a communication network such as the Internet, an intranet, or a dedicated line.

The measurement data sequentially stored in the Web server 12 as described above is connected to the LAN, and can be browsed and downloaded from the communication terminals 7 installed in the respective sections. As described above, the user can start the viewer program on the communication terminal 7 and refer to the downloaded data.

The Web server 11 can communicate with the database server 12 and has a management program. The Web server 11 operates in synchronization with the management program of the database server 12. . In the management program, the management data of the user who is the test requester is registered and an authentication number (such as a password) is assigned and recorded in a file for the user. 2 is assigned to which measurement test for which user, and a schedule is reserved for each user.

That is, each user accesses the Web server 11 using the communication terminal 7 arranged in each section, starts up the management program, and inputs the contents of the measurement test and the test period. Based on the input data, the assignment of the test equipment 2 used for the test and the test schedule are automatically created so as to be most efficiently performed. In the present embodiment, since the above data can be input not only to the Web server 11 but also to the database server 12, 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 once every hour, and unifies the management data between the servers 11 and 12. ing. 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”.

Each registration process (administrator registration, user registration, test equipment (including tester and chamber) registration)
Buttons (download buttons) for monitoring display of test equipment (chamber), monitor display of test equipment (chamber) and measurement data are arranged (see FIG. 7). In the case of this embodiment, the contents set by the operator are:
The test equipment registration (including tester and chamber) and the administrator and user information are registered, and the items normally set by the user via the communication terminal 7 are test assignment and schedule reservation, and monitor display of test equipment (chamber). The status can be checked with the button (download button) for referring to the viewer of the measurement data. However, these settings are not limited to the above-described embodiment, and a configuration in which some or all of the registration processing is performed by the operator, or a configuration in which the user performs some or all of the registration processing may be employed.

FIGS. 5 and 6 are diagrams for explaining the flow of data in the embodiment of FIG. 4, and show a data transfer request and where the data moves in response to the request. . That is, in the present embodiment shown in FIG.

0 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 facility 2 in advance, and confirms that the requested data has been transferred from the test facility 2 to the next test facility 2. A transfer request has been made. 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 then proceeds to each of the users set in the management program and the individual measurement tests 2 requested by the user. Based on the assignment status, the measurement data for each test facility in the database server 12 is extracted for each user, and the measurement data is transferred to a folder on the Web server 11 divided for each user.

The user's communication terminal 7 is composed of a personal computer,
The server b can be accessed (in the above-described embodiment, the operation is performed via the LAN, but the operation is the same, so the description is omitted). The Web server 11 permits a user who has been authenticated 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 7, the Web server 11 goes from the TOP page of the home page to the user-specific data page (not shown) and authenticates the user. After user authentication, the schedule reservation status for each user is displayed in a Gantt chart. Then, the measurement file corresponding to the user in the folder for each user can be downloaded.

The downloaded measurement data can be displayed on a display using a viewer program provided in the communication terminal 7. That is, the communication terminal 7 can check the schedule stored in the Web server 11 and download measurement data and documents registered for each user, and can download the measurement data downloaded on the screen of the monitor communication terminal 7. The data can be confirmed by the viewer.

As described above, in the case of this embodiment, the user
You can see new measurement data every day, so you can check the status of measurement data results every day. Therefore, even in the middle of the initially set test period, the user can terminate the measurement test, change the test period, or reserve a test for an empty test facility, based on the tendency of the obtained measurement data.
Alternatively, a change in the content of the measurement test can be determined at any time, so that an efficient measurement test can be performed.
In the present embodiment, a user who has obtained a specific authentication can execute the management program of the Web server 11 from his / her own communication terminal 7 so that the user can change the setting of the measurement test. You may.

In the above embodiment, the connection between the user's communication terminal 7 and the Web server 11 is performed using a LAN or an intranet. However, other various communication networks may be used. In the above configuration, the communication terminal 7 is connected to the Wen.
Although the configuration in which the measurement data stored in the Web server 11 is displayed or downloaded by connecting to the b server 11 has been described, the Web server 11 transmits the measurement data for each user via the communication network to the corresponding user. A configuration in which mail is delivered to a mobile phone or a mobile terminal (not shown) may be used.

Next, in this embodiment, the viewer program is
It is software that integrates and manages each viewer that can see measurement data of various test facilities. This viewer program is
Install it on the monitor communication terminal via LAN or the user's communication terminal via the Internet, and simply double-click the data downloaded from the homepage to launch various viewers that match the data and create the optimal form for measurement data. (FIG. 8)
