Abstract

PROBLEM TO BE SOLVED: To provide a networked analysis device system in which a plurality of users can access a data management server and that can protect file occupation for analysis while preventing unauthorized occupation of a file due to some accident, and a file management program for the system.SOLUTION: When there is a file being lent by a user who is not logged in to a system and is not in charge of analysis of any analysis device, file release processing for releasing the file from being lent is repeatedly executed at predetermined timing.

Description

  The present invention relates to a system in which an analysis apparatus and a client computer are connected to each other in a data communication network, and a program for operating the system. In particular, the present invention relates to a system and program for managing various files related to analysis such as analysis results.

  In the present invention, the analysis device includes all types of devices that measure the physical quantity of the sample to be measured.

  In recent years, by connecting a plurality of client terminals (for example, personal computers) and a data management server via a data communication network such as a LAN (local area network), and sharing and using a file stored in the data management server, Many network-type file management systems that centrally manage files are used in companies and the like.

  In the network type file management system, when a user wants to view or edit a certain file, the following file lending process is executed. This process will be described with reference to FIG.

  The user logs in to the system by operating the client terminal and inputting, for example, an ID and a password. When the login is completed normally, the user inputs a file lending request (file editing request) on the client terminal. Upon receiving this input, the file management module of the data management server determines whether the file can be lent to the database in which the file is stored, that is, whether the file is being rented to another user (other user). Inquire whether or not is being edited). If the file management module is not lent to another user, the file management module registers the file for rent to the database, and the status of the file is lent. Thereafter, the user can edit the file at the client terminal.

  When editing is completed, the user inputs a file return request (file editing completion instruction) at the client terminal and closes the file. In response to this operation, the file management module performs file return registration on the database, and the status of the file is released from being lent and becomes a status that can be lent.

JP2007-148876

  As described above, by properly managing the file lending status, multiple users can edit one file at the same time, resulting in inconsistencies in the file or damage to the file. It can be avoided.

  By the way, during the lending of a file, some error (for example, shutdown due to a power failure, computer crash, application error, etc.) may occur in a client terminal used by a user who is a lending target. In such a case, the file being edited at the client terminal at that time does not change its editing state on the file management module side of the data management server, and the lending state is maintained. If this happens, even if another user tries to open the file, the loan is rejected even though no one is actually editing it. Therefore, in order to solve such a problem, the conventional system is provided with a file forced release function for forcibly releasing the file lending state based on some criterion such as exceeding a predetermined time.

  On the other hand, also in the field of analyzers, in recent years, network type analyzer systems that connect a plurality of analyzers, a plurality of client terminals, and a data management server via a network have become mainstream (for example, Patent Document 1). In a network type analyzer system, various types of analyzers can be controlled from a single client terminal (usually a general computer), and a plurality of different client terminals can be connected to connect a plurality of different analyzer apparatuses. Since the analyzer can be controlled from a location, high convenience is provided to the user. Also in this network type analysis apparatus system, various files related to the analysis are centrally managed in the data management server.

  In the network type analyzer system, the user may directly edit the file in the data management server and may delegate access to the file to the analyzer. In the latter case, the user controls the analysis device from the client terminal, specifies a file in the data management server through the control, and causes the analysis device to access the file. As a result, the analysis apparatus inputs parameters necessary for analysis such as apparatus settings and analysis conditions from a file in the data management server, and outputs analysis results to a file in the data management server.

  However, if the lending state of the file being used is forcibly released while the analyzer is accessing the file in the data management server in this way, the analysis is interrupted. Further, as in the case of the network type file management system described above, there is a problem that the consistency of files in the data management server is impaired.

  The present invention is intended to solve the above-described problems, and its main purpose is to prevent unfair occupancy of a file due to some accident in a network type analyzer system in which a plurality of users can access a data management server. On the other hand, the exclusive use of files by analysis is to provide an analysis apparatus system and a file management program for the system that can be protected.

In order to solve the above problems, a network type analyzer system according to the present invention comprises:
A network-type analyzer system in which one or more analyzers, one or more client terminals, and a data management server that manages various files related to the analyzer are connected via a network,
The data management server is

Upon receiving a return request, a file lending unit that releases the file from being lent,
When there is a file that is being rented to a user who is not logged in to the system and who is not in charge of analysis of any analysis device, the file release process for releasing the file from being lent is executed repeatedly at a specified timing. A file release unit to perform,
It is characterized by having.

  In the network type analysis device system according to the present invention, the login management unit and the analysis device management unit of the data management server allow the user to log in to the system and the operating status of each analysis device (whether the analysis device is analyzing). Or who is the user in charge if analysis is in progress). Based on the management information of the login management unit and the analysis device management unit, the file release unit is rented to a user who has not logged in to this system and has not instructed any analysis device under analysis. Check if the file exists. If such a file exists, it can be determined that the file is being lent out due to some error and is not actually being edited by the user. Process to release. By adopting such a configuration, in the network type analyzer system, it is possible to appropriately manage files in the data management server while ensuring the continuation of analysis safely.

Further, a file management program for a network type analyzer system according to the present invention, which has been made to solve the above problems,
In a network-type analyzer system in which one or more analyzers, one or more client terminals, and a data management server that manages various files related to the analyzer are connected via a network,

It is made to function as.

  In the network type analyzer system and the file management program for the system according to the present invention, the file release unit detects a file that has been lent to a user who is not logged in to the system and is not under analysis, and so on. A file release process is periodically executed for a simple file at a predetermined timing. By performing such an operation, the file release unit can properly release the status of files that are still being edited from being lent even if something goes wrong in the client terminal or network. It can be used and edited by other users. On the other hand, since the file release processing is not performed for the file used by the analysis apparatus, the analysis is safely continued.

  Hereinafter, an embodiment of a network type analyzer system according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of an embodiment of a network type analyzer system according to the present invention. The network type analyzer system 1 of this embodiment (hereinafter abbreviated as “system 1” as appropriate) has a configuration described below.

  Acquisition of necessary information by controlling operations of client terminals T1 and T2, which are terminals operated by the user, a data management server DS for managing various data relating to analysis, analysis devices A1 to A4, and analysis devices A1 to A4 Controllers ACQ1 and ACQ2 are connected to each other via a system network NW that is a data communication network such as a local area network (LAN).

  The data management server DS includes a file storage unit 2 composed of a large-capacity storage medium such as a hard disk. Various files related to the analysis in the system 1 are stored in the file storage unit 2 in an integrated manner.

  The number and type of analyzers included in the network type analyzer system 1 may be anything. In this embodiment, two client terminals are connected, but this number can be changed as appropriate.

  The client terminals T1 and T2 are general-purpose computers, and a dedicated analysis application is installed. By using this analysis application, the user can issue an analysis execution instruction to the analysis devices A1 to A4, and can confirm the state of the analysis being performed. In addition, various files such as past analysis results stored in the file storage unit 2 of the data management server DS can be referred to and edited by the analysis application.

  The data management server DS includes a file lending unit 3 and a file releasing unit 4. Both the file lending unit 3 and the file releasing unit 4 execute a file management program installed in advance by the CPU (central processing unit) of the data management server DS cooperating with a storage area such as a memory or a hard disk. This is a software configuration realized by the above. In addition, the data management server DS controls login / logout of the user to the system 1 and manages the login management unit 5 for managing the access to the analysis devices A1 to A4 of the user who has logged into the system 1, An analysis device management unit 6 that manages whether or not each of the analysis devices A1 to A4 is under analysis, and a management data storage unit 7 that stores data for managing the system 1 are provided. These are also software configurations.

  FIG. 2 is a schematic configuration diagram of the management data storage unit 7 in the network type analyzer system 1 of the present embodiment. As shown in FIG. 2, in the management data storage unit 7, a system registration user table 10 that records user names registered in the system 1 and passwords of the respective users, and a login that records users who have logged in to the system 1. A medium user list 11, a lending file table 12 that records the status and lending user of each file stored in the file storage unit 2, and an apparatus operating status table 13 that records the statuses of the analysis apparatuses A1 to A4 and the user in charge , Is stored.

  Hereinafter, the operations of the file lending unit 3, the file releasing unit 4, the login management unit 5, the analysis device management unit 6, and the management data storage unit 7 will be specifically described.

  First, it is assumed that the user operates the client terminal T1 to activate the analysis application. When the user name and password are input after the analysis application is started, the login management unit 5 of the data management server DS causes the input user name and password name to be registered in the system registration user table 10. And the password are matched, and if they match, the user is permitted to log in to the system 1. This login information is recorded in the logged-in user list 11 by the login management unit 5.

  Various authorities for each user (for example, an administrator authority that allows all operations, a user authority that allows only analysis device operations and file editing / viewing, and only file viewing are permitted. If the visitor authority is set in advance, the user naturally performs an operation that is possible within the authority that has been granted. In this embodiment, it is assumed that the user is given all authority.

  After logging in to the system 1, the user can view and edit various files stored in the file storage unit 2 of the data management server DS via the analysis application of the client terminal T1. When it is desired to edit the file, the analysis application of the client terminal T1 displays a file selection screen as shown in FIG. 3 on the display screen of the client terminal T1. The user selects a desired file while referring to the file selection screen.

  In the file selection screen shown in FIG. 3, various files stored in the file storage unit 2 can be referred to. In the example of FIG. 3, four types of tabs of data, method, report, and batch are provided, and by selecting each tab, a corresponding type of file list is displayed. In the example of FIG. 3, the file “Data1.lcd” is currently opened by userA and is being edited.

  Here, it is assumed that the user operates the client terminal T1 (for example, clicks the mouse) to input that he wants to edit (or browse) a file “Data12224.lcd”, for example. Based on this operation, the client terminal T1 transmits a file rental request for “Data12224.lcd” to the data management server DS. Based on the transmission of the file lending request, the file lending unit 3 checks whether or not the status of “Data12224.lcd” is being lent.

  When “Data12224.lcd” is already lent to other users at the time of receiving the file lending request for “Data12224.lcd”, the file lending unit 3 edits (lending) “Data12224.lcd”. To refuse. In addition, by displaying a message such as “Data12224.lcd is currently being edited by another user and cannot be opened” on the analysis application screen, the user is instructed that editing is not possible. .

  When the status of “Data12224.lcd” is not lent at the time of receiving the file lending request for “Data12224.lcd”, the file lending unit 3 gives this user permission to edit “Data12224.lcd” Set the status of “Data12224.lcd” to Lending. As a result, the user can edit “Data12224.lcd” at the client terminal T1. The file lending unit 3 also changes the status of the file in the lending file table 12 to lending and records the lending user name.

  When the editing of “Data12224.lcd” is completed, the user performs a predetermined operation indicating the end of file editing (for example, pressing the close button) on the client terminal T1. Based on this operation, a file return request of “Data12224.lcd” is transmitted from the client terminal T1 to the data management server DS. Based on the transmission of the file return request, the file lending unit 3 disconnects the connection of “Data12224.lcd” to the client terminal T1, and simultaneously releases the status of “Data12224.lcd” from being lent. The file lending unit 3 also deletes the lending user name after setting the status of the file in the lending file table 12 to an access-free state.

  On the other hand, the user can also instruct the analysis apparatuses A1 to A4 to perform analysis via the analysis application of the client terminal T1. In this case, the analysis application of the client terminal T1 displays an analysis device selection screen as shown in FIG. 4 on the display screen of the client terminal T1. The user selects an analyzer while referring to the analyzer selection screen. In the display example of FIG. 4, it is shown that the analyzer “HPLC2” is currently used by userB and is being analyzed.

  Here, it is assumed that the user inputs that he / she wants to use an analyzer called “HPLC1” by operating the client terminal T1. Based on this operation, the client terminal T1 transmits an analyzer use request for “HPLC1” to the data management server DS. Based on the fact that the analyzer use request has been transmitted, the analyzer management unit 6 confirms whether the status of “HPLC1” is being analyzed.

  When “HPLC1” is already used by another user at the time of receiving the analyzer use request for “HPLC1”, the analyzer management unit 6 refuses to use “HPLC1”. Further, for example, by displaying a message such as “HPLC 1 cannot be used because another user is currently analyzing” on the screen of the analysis application, the user is instructed to disable use.

  When the status of “HPLC1” is not under analysis at the time of receiving an analyzer use request for “HPLC1”, the analyzer management unit 6 gives the user permission to use “HPLC1” and “HPLC1”. Set the status of during analysis. As a result, communication between the client terminal T1 and “HPLC1” is ensured, and the user can use “HPLC1”. The analysis device manager 6 also changes the status of the analysis device in the device operation status table 13 during analysis, and records the user name in charge.

  When communication between the client terminal T1 and “HPLC1” is ensured, an analysis instruction screen is displayed on the display screen of the terminal via the analysis application of the client terminal T1. The user can make a reservation for analysis, instruct execution of analysis, or perform detailed analysis settings by inputting on the analysis instruction screen.

In addition, when inputting analysis conditions on the analysis instruction screen, the user inputs values one by one and uses a file (method file) in which analysis conditions are stored in the data management server DS. Thus, the analysis conditions used in the past can be input at once. In addition, after newly creating a method file in the file storage unit 2, the analysis conditions input on the analysis instruction screen can be stored.
Also, when specifying a file (data file) to output analysis result data, use a file in the data management server DS or create a new data file and save it in the data management server DS Can do.

  When analysis is performed using method files and data files in the data management server DS, the use of these files is also managed by the file lending unit 3 in the same manner as described above, and the status of each file is determined for other users. Whether or not it is lent out. If these files are not lent, the files can be used, and the status of the file is set to lent. At the same time, the status of the file in the lending file table 12 is changed to lending, and the user name in charge of this analysis is recorded.

  As described above, the user can instruct the analysis apparatus from the client terminal T1, but even if the user in charge logs out while the analysis apparatus is executing the analysis, the analysis of the analysis apparatus is performed. Is executed as is. In this case, the status of the analysis device and the files (method file, data file, etc.) used for the analysis remain under analysis and lending. In addition, although the user name of the logged-out user disappears from the logged-in user list 11, the user name of the logged-out user remains recorded in the lending file table 12 and the apparatus operating status table 13. Therefore, even if the user in charge logs out, these analysis devices and files cannot be used by other users until the analysis is completed.

  When the analyzer finishes the analysis, the information is transmitted to the analyzer management unit 6. Here, the analyzer management unit 6 confirms whether or not the user in charge of the analyzer is logged out by referring to the logged-in user list 11. As a result, if the user in charge has logged out, the status of the analyzer is released. Further, the status of the analysis device in the lending file table 12 and the status of the analysis device in the device operation status table 13 is changed to an access-free state, and the name of the user in charge is deleted. On the other hand, when the responsible user is logged in and communication between the client terminal used by the responsible user and the analyzer is ensured, the status of the analyzer is maintained, and the lending file table 12 and the apparatus operating status are maintained. The status and user name of the analyzer in the table 13 are maintained.

  Next, the operation of the file release unit 4 will be described with reference to FIG. The file release unit 4 performs the following file release operation at a predetermined timing (for example, once in the stage before executing the backup in which the operation amount of the analyzer is predicted to be the smallest during the day). Do.

(A) Acquisition of file renting user information The file release unit 4 determines which file is currently lent to which user among the files stored in the file storage unit 2 and the rented file and the renting user. Is confirmed by referring to the lending file table 12 associated with. In this example, it is known from the lending file table 12 that the A file is rented to the user B, the B file is to the user E, the C file is to the user A, and the D file is being lent to the user D. “User A, User B, User D, User E” are determined.

(B) Acquisition of Logout User Information Next, the file release unit 4 includes a system registration user table 10 in which information of all users registered in the system 1 is described, and all users who are currently logged in to the system 1. The currently logged out users are listed by comparing the logged-in user list 11 described. In the example of FIG. 5, it is determined that the logged out user is “user D, user E”.

(C) Acquisition of user information under analysis Further, the file release unit 4 refers to the device operation status table 13 in which the operation status of each of the analysis devices A1 to A4 is described, and lists the users who are currently analyzing . As described above, in the system 1 according to the present invention, it is possible for a certain user to continue executing the analysis while logging out of the system 1. In the example of FIG. 5, it is determined that the user under analysis is “user A, user B”.

(D) Confirmation of file release target user From the above processes (A), (B), and (C), the file release unit 4 is not logged in to the system 1, that is, is logging out ((B ) Information) and a user who is not executing analysis (information of (C)) and a user whose file is being lent (information of (A)) is checked. In the example of FIG. 5, the user E corresponds to this.

(E) Execution of File Release Processing The file release unit 4 releases a file lent to the user E from being lent. In the example of FIG. 5, the status of the B file is released from being lent.

  As described above, the file release unit 4 executes the file release process.

  As mentioned above, although the network type analyzer system according to the present invention has been described by using the embodiments, it is obvious that the above is only an example, and changes, modifications, or additions are appropriately made within the scope of the present invention. You can go.

  For example, the list of file lending users, the list of logout users, and the list of users under analysis may be prepared in advance separately from the execution of the file release process of the file release unit 4. In addition, the file release unit 4 may generate each time.

  Moreover, in the said Example, although the login management part 5 was contained in the data management server DS, according to the form of the system 1, it may be provided anywhere. For example, when a system server that manages the entire system 1 is separately provided, the login management unit 5 can be included in the system server.

  Furthermore, the execution timing and the number of times of file release processing are not limited to the above example, and may be set as appropriate. It may be executed whenever a file release processing execution request is received from a client terminal.
