[0004] Recently, systems have been considered in which multiple measuring devices are connected to a single host computer, and the host computer manages the authority defined for each measuring device and the operation logs (audit trails) of users to whom the authority has been assigned. The management of the authority and operation logs can be performed, for example, using a management program called DI (Data Integrity) software. In particular, in the pharmaceutical field, stricter data management is required, and data management based on a management program has become extremely important.

[0005] In order to expand a system, it may be necessary to connect a new measurement device to a host computer to which multiple measurement devices are already connected. To manage the permissions and operation logs of the newly added measurement device, for example, it is possible to rewrite the existing management program (including overwriting, upgrading, or modifying the program) to a program that can also handle the new measurement device. However, rewriting the existing management program requires the user of the system to verify or evaluate whether the rewritten management program operates normally and appropriately, which increases the burden on the user. Therefore, it is desirable to manage permissions and operation logs without rewriting the existing management program.

[0006] The present invention has been made to solve the above problems, and its purpose is to provide a host computer, a measurement system, an authority management method, and a management program that can manage authority and operation logs without rewriting existing management programs, even when a new measurement device is added to the system.

[0007] A host computer according to one aspect of the present invention is a host computer to which a measurement device is connected, which receives authority information indicating authority defined in the measurement device from the measurement device and stores the authority information.

[0008] A measurement system according to another aspect of the present invention includes the host computer described above and a plurality of measurement devices connected to the host computer.

[0009] A further aspect of the present invention relates to an authority management method in a host computer to which a measuring device is connected, and includes an authority information storage step of receiving authority information indicating the authority defined in the measuring device from the measuring device and storing the authority information.

[0010] A management program according to yet another aspect of the present invention is a management program for causing a host computer to which a measuring device is connected to perform authority management, and for causing the host computer to execute an authority information storage step of receiving authority information indicating the authority defined in the measuring device from the measuring device and storing the authority information.

[0011] According to the present invention, even when a new measuring device is added to a system, it is possible to manage the authority and operation log without rewriting the existing management program.

[0013] Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. In this specification, "management" means controlling the whole so that it does not deviate from a certain standard.

[0014] 1. Measurement System FIG. 1 is a block diagram showing a schematic configuration of a measurement system 100 according to this embodiment. The measurement system 100 is configured by connecting a plurality of measurement devices 80 to a host computer 1 via a communication line so that the devices can communicate with each other. The communication line may be wired or wireless. For convenience, FIG. 1 shows a first measurement device 80a, a second measurement device 80b, and a third measurement device 80c as the plurality of measurement devices 80. The number of the plurality of measurement devices 80 is not particularly limited and may be two, four, or more. Various measurement (analysis) devices, such as an X-ray analyzer, a Raman spectrometer, or a water quality analyzer, can be used as the measurement devices 80.

[0015] The host computer 1 includes a database 2 , an input unit 3 , a display unit 4 , a communication unit 5 , and a control unit 6 .

[0016] The database 2 is a memory that stores various types of information, and is configured to include a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (Hard Disk Drive), an SSD (Solid State Drive), or a non-volatile memory.

[0017] The database 2 includes a host information database 21, a measurement information database 22, and a management information database 23. The host information database 21 stores the operating program of the host computer 1 as well as setting information for the host computer 1 (for example, setting information for the display on the display unit 4).

[0018] The measurement information database 22 stores control programs and measurement information for each of the multiple measurement devices 80. The measurement information includes measurement data (including spectra and mapping) acquired by each measurement device 80 and setting information managed by each measurement device 80. The setting information also includes information regarding option settings and calibration for each measurement device 80. The measurement information is transmitted from each measurement device 80 to the host computer 1 via a communication line and stored in the measurement information database 22. The control programs are transmitted, for example, from each measurement device 80 via a communication line and stored in the measurement information database 22. The control programs may be downloaded from a specific server and stored in the measurement information database 22. Alternatively, a reading unit (not shown) of the host computer 1 may read the control programs from a recording medium storing the control programs and store them in the measurement information database 22.

[0019] The management information database 23 is a memory that stores information necessary for DI (Data Integrity) control, and includes a management program storage unit 23a, an authority information storage unit 23b, and an operation log storage unit 23c.

[0020] The management program storage unit 23a stores a management program called DI software, which is an authority management program for managing authority information and operation logs, which will be described later.

[0021] The authority information storage unit 23b stores authority information indicating the authority defined for each of the multiple measurement devices 80 for each measurement device 80. Examples of the authority include access authority that permits access to a specific measurement device 80, operator authority that permits operation as an operator for a specific measurement device 80, administrator authority that permits operation as an administrator, and authority that permits various settings. When the measurement device 80 is connected to the host computer 1, the authority information is transmitted from the measurement device 80 to the host computer 1 and stored in the authority information storage unit 23b. The authority information storage unit 23b also stores information set by a user with administrator authority (hereinafter simply referred to as an "administrator"), specifically, an authority group including at least one authority and account information of a user to be assigned to the authority group, the details of which will be described later.

[0022] The operation log storage unit 23c stores the operation log of the user to whom the authority is assigned (i.e., the operation log of the input unit 3) on the host computer 1. Therefore, for example, information on when, who, and what was done (what kind of operation was performed) is stored in the operation log storage unit 23c as an operation log.

[0023] The input unit 3 is an operation unit that accepts user operations. The input unit 3 is configured to include, for example, a keyboard, a mouse, or a mouse pad. A user who has been assigned a predetermined authority can operate the input unit 3 to issue instructions (e.g., an instruction to start measurement) to the measurement device 80. The measurement device 80 performs an operation (e.g., a measurement operation) based on the instruction.

[0024] The display unit 4 is configured, for example, as a liquid crystal display device, and displays various types of information. The display unit 4 may also be configured as a display device with a touch panel. In this case, the touch panel can constitute the input unit 3. The communication unit 5 is a module (communication module) that serves as a communication interface for the host computer 1 to communicate with multiple measuring devices 80.

[0025] The control unit 6 is composed of a central processing unit called a CPU (Central Processing Unit). The control unit 6 includes an overall control unit 61 and a management control unit 62. The overall control unit 61 executes an operating program stored in the host information database 21 to control the operation of each unit of the host computer 1. The management control unit 62 executes a management program stored in the management program storage unit 23a of the management information database 23. This allows management of authorities and operation logs. In other words, authority information is registered in the authority information storage unit 23b, and operation logs are registered in the operation log storage unit 23c.

[0026] [2. Authorization Management Method] Next, an authorization management method in the measurement system 100 configured as described above will be described. Figure 2 shows an example of authorization information stored in the authorization information storage unit 23b when a first measurement device 80a and a second measurement device 80b are connected to the host computer 1, but a third measurement device 80c is not connected. As shown in the figure, if authorizations A to D are defined for the first measurement device 80a and authorizations E to G are defined for the second measurement device 80b, authorization information including these authorizations A to G is stored in the authorization information storage unit 23b for each measurement device 80 (distinguished between the first measurement device 80a and the second measurement device 80b). Authorities A to G are different from each other, such as the access authorization and operator authorization described above.

[0027] Note that authority A may be, for example, access authority to the first measuring device 80a, and authority E may be access authority to the second measuring device 80b. In this case, authority A and authority E have the same access authority but different access targets. In this respect, authority A and authority E are considered to be different (distinguished) from each other.

[0028] By executing the management program, the management control unit 62 stores and manages the operation logs of users who have been assigned the authority (authorities A to G) stored in the authority information storage unit 23b in the operation log storage unit 23c.

[0029] 3 is a flowchart showing the processing flow of the authority management method when a third measuring device 80c is additionally connected to the host computer 1. When the third measuring device 80c is connected to the host computer 1 via a communication line (S1), the third measuring device 80c outputs (transmits) necessary information to the host computer 1 and submits a request to register the necessary information (S2). The necessary information includes, for example, the model name of the third measuring device 80c, the device's unique number, and the type of authority defined in the third measuring device 80c.

[0030] When the host computer 1 acquires the necessary information via the communication unit 5, the management control unit 62, based on the management program, stores the authority information regarding the authority of the third measuring device 80c from the above necessary information in the authority information storage unit 23b of the management information database 23, and stores the remaining information in the measurement information database 22 (S3; authority information storage step).

[0031] More specifically, when the management control unit 62 receives the registration request from the third measuring device 80c (S31; application receiving step), it automatically registers the authority information included in the necessary information in the authority information storage unit 23b (S32; registration step). If necessary, an authentication receiving step for receiving authentication by an administrator may be provided between S31 and S32. Then, the authority information may be automatically registered in S32 only if authentication (approval of the application) is obtained by the administrator in the authentication receiving step. The administrator's authentication is received by operating the input unit 3.

[0032] The authority information for the first measuring device 80a and the second measuring device 80b is registered in the authority information storage unit 23b in the same manner as in S1 to S3.

[0033] 4 shows an example of authority information stored in the authority information storage unit 23b when a third measurement device 80c is newly connected to the host computer 1. As shown in the figure, when authorities H to I are set in the third measurement device 80c, authority information including these authorities H to I is stored in the authority information storage unit 23b. Note that authorities A to I are different authorities from each other.

[0034] Based on the authority information stored in the authority information storage unit 23b, the management control unit 62 stores in the operation log storage unit 23c an operation log of the input unit 3 of a user to whom an authority (authorities A to I) included in the authority information is assigned (S4; operation log storage step). Therefore, for example, when a user having some authority for the third measuring device 80c operates the input unit 3, in S4, the management control unit 62 controls the operation log of the third measuring device 80c to be stored in the authority information storage unit 23b.

[0035] As described above, the host computer 1 of this embodiment is a computer to which the measuring device 80 is connected, and receives authority information indicating the authority defined in the measuring device 80 from the measuring device 80, and stores the received authority information in the authority information storage unit 23b (S3). Note that, in this example of this embodiment, the measuring device 80 may be any of the first measuring device 80a to the third measuring device 80c, but here we will consider the first measuring device 80a as an example.

[0036] In this way, the authority information of the measuring device 80 connected to the host computer 1 is stored in the authority information storage unit 23b. As a result, the management control unit 62 can store and manage operation logs of users assigned with the authority indicated by the authority information in the operation log storage unit 23c based on the authority information stored in the authority information storage unit 23b. Therefore, once an operation program (management program) for managing operation logs based on the authority information stored in the authority information storage unit 23b is established, even if a new measuring device 80 (e.g., a third measuring device 80c) is connected to the host computer 1, the management control unit 62 can execute the operation program to store and manage operation logs of users assigned with authority for the new measuring device 80 in the operation log storage unit 23c (see FIG. 4 ). In other words, even if a new measuring device 80 is added to the system, the authority and operation log can be managed without rewriting the management program (e.g., overwriting, upgrading, modifying, etc.). In other words, the same management program can be used to manage the authority and operation log whether the measuring device 80 is added or not. Furthermore, when performing authority management on the host computer 1, the authority indicated by the authority information stored in the authority information storage unit 23b can be matched with the authority defined in the measuring device 80, thereby enabling smooth implementation of authority management.

[0037] The authority management method of this embodiment includes an authority information storage step (S3). As a result, even when a new measuring device 80 is connected to the host computer 1, the management control unit 62 can manage the authority and operation log for the added measuring device 80 using the same management program as before the addition, as described above. Therefore, there is no need to rewrite the management program in response to the addition of the measuring device 80.

[0038] Furthermore, when a new measuring device 80 is connected to the host computer 1 (S1), the management control unit 62 acquires authority information indicating the authority defined in the new measuring device 80 from the new measuring device 80 and stores it in the authority information storage unit 23b (S3). The authority information of the new measuring device 80 can be automatically registered in the authority information storage unit 23b by the management control unit 62 simply by connecting the new measuring device 80 to the host computer 1.

[0039] The authority information storage step (S3) includes an application acceptance step (S31) and a registration step (S32). When a new measuring device 80 is connected to the host computer 1, the authority information can be registered in the authority information storage unit 23b based on a registration application request from the new measuring device 80.

[0040] The measurement system 100 of this embodiment is configured by connecting a plurality of measurement devices 80 to the above-described host computer 1. According to the configuration of this embodiment, as described above, even when a new measurement device 80 is additionally connected to the host computer 1, it is possible to manage the authority and operation log without rewriting the management program. Therefore, it is easy to expand the system by increasing the number of measurement devices 80 connected to the host computer 1.

[0041] The above describes a configuration in which the management information database 23 is provided inside the host computer 1. That is, the host computer 1 includes an operation log storage unit 23c and an authority information storage unit 23b, and the management control unit 62 stores authority information for each measurement device 80 in the authority information storage unit 23b (see FIGS. 2 and 4). However, the host computer 1 is not limited to a configuration that includes the management information database 23. For example, the management information database 23 may be provided outside the host computer 1. That is, the operation log storage unit 23c and the authority information storage unit 23b may be provided outside the host computer 1. The management information database 23 may also be configured to be able to communicate with the host computer 1 via wired or wireless communication. In this case, the management information database 23 refers to a server, a drive, or storage.

[0042] Furthermore, although the above describes an example in which the authority information of the measuring device 80 is stored in the authority information storage unit 23b under the control of the management control unit 62 of the host computer 1, the present invention is not limited to this example. For example, when the measuring device 80 is connected to the host computer 1, the measuring device 80 may not submit a request to register the authority information to the host computer 1, but may instead directly transmit the authority information from the measuring device 80 to the host computer 1 and store it in the authority information storage unit 23b. In this case, control by the management control unit 62, specifically, control by the management control unit 62 to store the authority information in the authority information storage unit 23b, can be eliminated.

[0043] 3. Setting Authority Groups and Users (3-1. Overview) In this embodiment, the administrator can set and add authority groups by operating the input unit 3, and can also set users to whom authority is assigned for each authority group. These points will be described in detail below.

[0044] 5 schematically shows an example of authority groups and users set by an administrator when a first measuring device 80a and a second measuring device 80b are connected to the host computer 1 as multiple measuring devices 80. In the example shown in the figure, of the authorities A to D defined in the first measuring device 80a, authorities A to C are grouped together to set up authority group G1, and authority D is set up alone as authority group G3. Furthermore, of the authorities E to G defined in the second measuring device 80b, authorities E to F are grouped together to set up authority group G2. User U1 is assigned to authority group G1, users U2 and U3 are assigned to authority group G2, and user U3 is assigned to authority group G3.

[0045] With these settings, for example, user U1 can perform operations on the first measuring device 80a corresponding to authorities A to C included in authority group G1. Users U2 and U3 can perform operations on the second measuring device 80b corresponding to authorities E to F included in authority group G2. User U3 can perform operations on the first measuring device 80a corresponding to authority D included in authority group G3.

[0046] Information about the authority groups G1 to G3 and the account information about the users U1 to U3 assigned to the authority groups G1 to G3 are stored in the authority information storage unit 23b together with the information about the authorities A to G described above.

[0047] 6 shows an example of authority groups and users set by an administrator when a third measuring device 80c is newly connected to the host computer 1 in addition to the first measuring device 80a and second measuring device 80b. In the settings of FIG. 6, in addition to the settings of FIG. 5, of the authorities H to I defined in the third measuring device 80c, only authority I is set as authority group G4. User U3 is then assigned to authority group G4.

[0048] This setting allows user U3 to perform operations corresponding to the authorities included in authority groups G2 to G4 on the measurement device 80. Specifically, user U3 can perform operations corresponding to authorities E to F included in authority group G2 on the second measurement device 80b. Furthermore, user U3 can perform operations corresponding to authority D included in authority group G3 on the first measurement device 80a. Furthermore, user U3 can perform operations corresponding to authority I included in authority group G4 on the third measurement device 80c.

[0049] The information on the authority group G4 and the account information of the user U3 assigned to the authority group G4 are stored in the authority information storage unit 23b together with the information on the authorities A to I described above.

[0050] 7 schematically shows another example of authority groups and users set by the administrator when a third measuring device 80c is newly connected to the host computer 1 in addition to the first measuring device 80a and the second measuring device 80b. In the setting in FIG. 7, in addition to the setting in FIG. 5, of the authorities H to I defined in the third measuring device 80c, authority I is additionally set to authority group G1.

[0051] With this setting, the user U1 can perform operations corresponding to the authorities A to C included in the authority group G1 on the first measuring device 80a. Furthermore, the user U1 can perform operations corresponding to the authority I included in the authority group G1 on the third measuring device 80c.

[0052] (3-2. Display Screen Examples) The above-mentioned setting of authority groups and users can be performed on the display screen of the display unit 4. Fig. 8 is a flowchart showing the procedure for setting authority groups and users. Figs. 9 to 14 schematically show examples of the display screen of the display unit 4.

[0053] (3-2-1. Setting of Authority Group) First, the administrator operates the input unit 3 to display the group setting screen 4a shown in Fig. 9 on the display unit 4. Then, in the authority group display area D1 of the group setting screen 4a, the administrator manually inputs the group name and group ID of the authority group to be set using the input unit 3 (S51). The example of Fig. 9 shows a state in which authority group G1 and its group ID have been input as the authority group.

[0054] Next, the administrator selects and inputs the measuring device 80 that has the authority to be assigned to the authority group G1 from the pull-down menu in the measuring device selection area D2 of the group setting screen 4a. The example in FIG. 9 shows a state in which the first measuring device 80a has been selected. In this case, authorities A to D of the selected first measuring device 80a are displayed in the authority display area D10 of the group setting screen 4a. The administrator can select the authority to be set by operating the input unit 3. The example in FIG. 9 shows a state in which authorities A to C have been selected from authorities A to D of the first measuring device 80a. As a result, authorities A to C of the first measuring device 80a are set as authorities to be included in the authority group G1. In other words, the authority group G1 is set.

[0055] If there are no other authorities (e.g., authorities for other measuring devices 80) to be assigned to the authority group G1, the administrator can simply click the end button B2 displayed on the group setting screen 4a using the input unit 3. This completes the setting of the authority group G1.

[0056] On the other hand, if the administrator wishes to set additional authority for another measuring device 80 to the authority group G1, the administrator clicks the Add button B1 displayed on the group setting screen 4a using the input unit 3. Then, as shown in FIG. 10, an Add selection area D3 is displayed on the group setting screen 4a. Therefore, the administrator can operate the pull-down menu in the Add selection area D3 to select and input an additional measuring device 80 that has authority to be assigned to the authority group G1, as shown in FIG. 11. The example in FIG. 11 shows a state in which the third measuring device 80c has been selected. In this case, authorities H to I of the selected third measuring device 80c are displayed alongside authorities A to D of the first measuring device 80a in the authority display area D10 of the group setting screen 4a.

[0057] The administrator can select the authority to be set for the third measuring device 80c by operating the input unit 3. The example in Fig. 11 shows a state in which authority I is selected from authorities H to I for the third measuring device 80c. As a result, authority I for the third measuring device 80c is additionally set as an authority to be included in authority group G1.

[0058] If there are other measuring devices 80 that have the authority to be included in the authority group G1, simply click the Add button B1 in the same way. This will cause the same display as above to be displayed, and the same selection input as above can be performed.

[0059] Thereafter, for other authority groups such as authority group G2, the same method as above can be used to set the authorities to be included in the authority group, that is, to set the authority group (S52).

[0060] (3-2-2. User Settings) Next, the administrator operates the input unit 3 to display a user settings screen 4b shown in Fig. 12 on the display unit 4. Then, in the user information display area D5 of the user settings screen 4b, the administrator manually inputs the account information (user name and user ID) of the user to be set using the input unit 3 (S54). The example in Fig. 12 shows a state in which user U3 and his user ID have been input as the user.

[0061] Next, the administrator selects and inputs the authority group to be assigned to user U3 from the pull-down menu in the authority group selection field D6 of the user setting screen 4b. The example of Fig. 12 shows that authority group G2 has been selected. In this case, authorities E to F included in the selected authority group G2 are displayed in the authority group display field D20 of the user setting screen 4b.

[0062] If there are no other authority groups to be assigned to user U3, the administrator can simply click the Finish button B4 on the user setting screen 4b using the input unit 3. This completes the setting of the authority group to be assigned to user U3. In other words, user U3 is set as the user to whom authorities E to F included in authority group G2 are assigned.

[0063] On the other hand, if the administrator wishes to assign another authority group to user U3, the administrator uses the input unit 3 to click the Add button B3 displayed on the user setting screen 4b. This causes an additional selection area D7 to appear on the user setting screen 4b, as shown in FIG. 13 . Therefore, the administrator can operate the pull-down menu in the additional selection area D7 to select and input an additional authority group to be assigned to user U3, as shown in FIG. 14 . The example in FIG. 14 shows a state in which authority group G3 has been selected. In this case, authority D included in the selected authority group G3 is displayed alongside authorities E to F included in authority group G2 in the authority group display area D20 on the user setting screen 4b.

[0064] If there is another authority group to be assigned to user U3, the user can click the Add button B3 in the same way. This will cause the same display as above to be displayed, and the user can make the same selection and input as above.

[0065] Hereinafter, for other users such as user U1, the authority groups to be assigned to the users can be set in the same manner as above. In other words, the users to whom the authorities included in the authority groups are assigned can be set (S54).

[0066] 5 to 7, when an authority group including at least one authority is set by the input unit 3, the authority information storage unit 23b further stores the authority group in addition to the authority. This allows authorities assigned to users to be managed collectively (as an authority group) in the authority information storage unit 23b.

[0067] Furthermore, the authority information storage unit 23b further stores account information indicating the user's account when a user to be assigned to an authority group is set by the input unit 3. This allows the authority group and the user to be linked and managed by the authority information storage unit 23b.

[0068] 9 to 14, in this embodiment, the display unit 4 of the host computer 1 displays at least one of authority, authority group, and user account (account information) in a configurable manner. This allows, for example, a system administrator to set authority, authority group, and user to be assigned the authority by operating the input unit 3 while looking at the display screen of the display unit 4. Furthermore, even when a new measurement device 80 is additionally connected to the host computer 1, it is possible to add the authority defined in the new measurement device 80 to an existing authority group, and also possible to add the authority as a new authority group.

[0069] 11, when an authority group includes authorities defined for at least two measurement devices 80, the display unit 4 displays the authorities arranged for each measurement device 80 (see FIG. 11). This allows the system administrator to check the display unit 4 and confirm that the authority group includes authorities for multiple measurement devices.

[0070] [4. Program] The host computer 1 of this embodiment can be configured as a computer on which an operating program (application software) is installed. The host computer 1 (particularly the control unit 6) reads and executes the program, thereby operating each unit of the host computer 1 and executing each of the processes (steps) described above. Such a program is obtained, for example, by downloading it from an external device via a network and stored in the database 2.
