Description

  The present invention relates to an analysis device control system, an analysis device control method, an analysis device control program, and an analysis system including the analysis device.

  In recent years, in the manufacturing industry and the inspection industry, it has been required to ensure the traceability (traceability) of electronic data obtained by an analyzer and to prevent falsification of electronic data and the like. For this reason, the authority to use each analyzer is given only to a specific person, and the person having the authority to operate is limited for each operation content of each analyzer (see, for example, Patent Document 1).

  In the analyzer described in Patent Literature 1, authority items corresponding to each of a plurality of processes executed for analysis are stored. Also, the correspondence between authority items and authority names is stored, and the correspondence between user information and authority names is stored. The authority name is authenticated based on the user information input from the input device, and the authority item based on the authenticated authority name is executed.

JP 2005-327080 A

  In the analysis apparatus described in Patent Literature 1, each user can execute only authority items given in advance. In addition, after an authorized user performs input processing using the input device, input processing becomes impossible when input processing is not performed within a certain lockout time. This prevents a third party from entering the measurement location and changing the measurement conditions or tampering with the measurement data when the authorized user leaves the measurement location.

  However, if a legitimate user does not perform input processing within the lockout time, it is necessary to perform re-authentication by inputting user information from the input device in order to continue measurement. In this case, the user of the analyzer often wears protective gloves in order to prepare a measurement object such as weighing and addition of a reagent. When touching an input device such as a touch panel or a keyboard with a finger wearing protective gloves, the input device may not respond. Also, chemicals attached to protective gloves may damage the input device. Therefore, the user must remove the protective gloves and perform re-authentication. As described above, the re-authentication in the analyzer involves complicated work.

  An object of the present invention is to provide an analysis apparatus control system, a control method, and an analysis apparatus capable of reliably prohibiting an operation by a person who does not have an operation authority while improving convenience of an operation by a person having an operation authority for each operation content It is to provide a control program as well as an analysis system.

  (1) The control system for an analyzer according to the present invention includes a login authentication unit that places the control system in a login state based on login authentication, a voice input unit that inputs the voice of the user of the analyzer, and the control system logs in A voice recognition unit that detects an operation command and a voiceprint by a voice recognition function from the voice input by the voice input unit, and whether or not the detected voiceprint matches the voiceprint of the person who has logged in to the control system A voiceprint determination unit that determines whether or not the logged-in person has an operation authority according to the detected operation command, and the detected voiceprint matches the voiceprint of the logged-in person and logged in An operation command supply unit that gives the detected operation command to the analyzer when the person has an operation authority based on the detected operation command; Provided.

  In the control system, when a voice is input by the user in a login state, an operation command and a voiceprint are detected from the voice. It is determined whether or not the detected voiceprint matches the voiceprint of the person who has logged into the control system, and it is determined whether or not the logged-in person has the operation authority for the detected operation command. When the detected voiceprint matches the voiceprint of the logged-in person and the logged-in person has the operation authority based on the detected operation command, the detected operation command is given to the analyzer. This makes it impossible for a person other than the logged-in person to operate the analyzer by voice. Further, even a logged-in person cannot perform an operation without operating authority. In this case, the user can instruct the operation of the analyzer by voice without performing work such as removing protective gloves. Therefore, it is possible to reliably prohibit an operation by a person who does not have the operation authority while improving the convenience of the operation by the person having the operation authority for each operation content.

  (2) The control system records, as an operation log, information indicating an operation command or operation content given to the analysis apparatus, information indicating a person who has instructed an operation using the operation command, and information indicating an operation time A part may be further provided.

  In this case, it is possible to recognize the operation content of the analyzer, the person who instructed the operation, and the operation time based on the operation log. This ensures traceability of the analysis results.

  (3) The control system further includes a storage unit that stores voice print information indicating a voice print of a right-of-use person who has the right to use the analysis apparatus, and operation right information indicating whether or not each of the right-of-use authority has an operation right by each operation command. The voiceprint determination unit determines whether the detected voiceprint matches the voiceprint of the logged-in person based on the voiceprint information stored in the storage unit, and the operation authority determination unit is stored in the storage unit. Based on the operation authority information, it may be determined whether or not the logged-in person has the operation authority based on the detected operation command.

  In this case, based on the operation authority information, whether or not the voice print of the voice input by the voice input unit matches the voice print of the logged-in person and whether or not the logged-in person has the operation authority for the operation content designated by the voice. Can be easily determined. In addition, by changing the operation authority information stored in the storage unit, the person having the operation authority can be changed for each operation content.

  (4) An analysis system according to the present invention includes an analysis device and the control system described above, and the analysis device executes an operation command given by the control system.

  Since the analysis system includes the above-described control system, it is possible to reliably prohibit an operation by a person who does not have the operation authority while improving convenience of operation by a person who has the operation authority for each operation content.

  (5) The method for controlling an analyzer according to the present invention includes a step of setting the control system of the analyzer to a login state based on login authentication, a step of inputting a voice of a user of the analyzer, and the control system being in a login state The step of detecting an operation command and a voiceprint by a voice recognition function from the voice input by the voice input unit, and determining whether or not the detected voiceprint matches the voiceprint of the person who has logged into the control system A step, a step of determining whether or not the logged-in person has the operation authority according to the detected operation command, and the detected voiceprint matches the voiceprint of the logged-in person and the logged-in person is detected A step of giving the detected operation command to the analysis apparatus when having the operation authority.

  According to the control method, it becomes impossible for a person other than the logged-in person to operate the analyzer by voice. Further, even a logged-in person cannot perform an operation without operating authority. In this case, the user can instruct the operation of the analyzer by voice without performing work such as removing protective gloves. Therefore, it is possible to reliably prohibit an operation by a person who does not have the operation authority while improving the convenience of the operation by the person having the operation authority for each operation content.

  (6) The control program for the analyzer according to the present invention includes a process for setting the control program in a login state based on login authentication, a process for inputting the voice of the user of the analyzer, and the control program in the login state. In addition, a process for detecting an operation command and a voiceprint from the input voice by a voice recognition function, a process for determining whether or not the detected voiceprint matches a voiceprint of a person who has logged into the control program, and a person who has logged in When determining whether or not to have an operation authority by the detected operation command, and when the detected voiceprint matches the voiceprint of the logged-in person and the logged-in person has the operational authority by the detected operation command, This is for causing the computer to execute the process of giving the detected operation command to the analyzer.

  According to the control program, it becomes impossible for a person other than the logged-in person to operate the analyzer by voice. Further, even a logged-in person cannot perform an operation without operating authority. In this case, the user can instruct the operation of the analyzer by voice without performing work such as removing protective gloves. Therefore, it is possible to reliably prohibit an operation by a person who does not have the operation authority while improving the convenience of the operation by the person having the operation authority for each operation content.

(1) Configuration of Analysis System FIG. 1 is a block diagram showing a configuration of an analysis system according to an embodiment of the present invention. The analysis system 100 in FIG. 1 includes a control system 1 and an analysis apparatus 2. The control system 1 includes an information input unit 10, a voice input unit 20, a display unit 30, a data processing device 40, a storage device 50, and an output device 60.

  The information input unit 10 includes a keyboard, a pointing device, and the like, and is used for inputting login information and other information. The voice input unit 20 includes a microphone or the like, and is used to input a speaker's voice as a voice signal. The display unit 30 includes a liquid crystal display and displays various information and images.

  The data processing device 40 includes a use authority determination unit 11, a voice recognition unit 12, an operation authority determination unit 13, a table acquisition unit 14, a voiceprint determination unit 15, an operation command supply unit 16, and an operation log recording unit 17. The data processing device 40 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and is a personal computer, for example. When the CPU executes a control program that is a computer program stored in a storage medium (recording medium) such as the ROM or the storage device 50, the functions of the above-described components (11 to 17) are realized. Some or all of the components of the data processing device 40 may be realized by hardware such as an electronic circuit. The information input unit 10 and the use authority determination unit 11 constitute a login authentication unit 18.

  The use authority determination unit 11 performs login authentication. Specifically, the use authority determining unit 11 includes login information input by the information input unit 10 and login information of a use authority having the use authority of the analyzer 2 based on a user-authority correspondence table TB described later. If the input login information matches the login information of the authorized user, the control program of the control system 1 is set in the login state. In addition, when the information input unit 10 inputs a logout instruction, the use authority determination unit 11 puts the control program of the control system 1 into a logout state. Hereinafter, a person who logs in the control program by inputting login information is referred to as a login user.

  The table acquisition unit 14 acquires a user-authority correspondence table TB, which will be described later, stored in the storage device 50. The voice recognition unit 12 detects an operation command and a voiceprint of a speaker from the voice signal input by the voice input unit 20 using a voice recognition function. The voiceprint determination unit 15 determines whether the voiceprint of the logged-in user matches the voiceprint detected by the voice recognition unit 12 based on the user-authority correspondence table TB. The operation authority determination unit 13 determines whether the login user has an operation authority based on the operation command detected by the voice recognition unit 12 based on the user-authority correspondence table TB.

  The operation command supply unit 16 detects an operation detected when the voiceprint detected by the voice recognition unit 12 matches the voiceprint of the logged-in user and the logged-in user has an operation authority based on the operation command detected by the voice recognition unit 12. A command is given to the analyzer 2. The operation log recording unit 17 indicates identification information for identifying a person (login user) who has instructed an operation by an operation command by voice, operation information indicating an operation content by an operation command given to the analyzer 2, and an operation time. The time information is recorded in the storage device 50 as the operation log LG. In the present embodiment, the operation information includes an operation command and an operation content designated by the operation command.

  The storage device 50 includes a storage medium such as a hard disk, an optical disk, a magnetic disk, a semiconductor memory, or a memory card, and stores a user-authority correspondence table TB and an operation log LG. The output device 60 includes a printing device or a display device, and prints data such as an operation log LG on a paper medium or displays it on a screen. The analyzer 2 is, for example, a liquid chromatograph or a gas chromatograph.

(2) User-authority correspondence table TB
FIG. 2 is a diagram showing an example of the user-authority correspondence table TB. The user-authority correspondence table TB in FIG. 2 includes the correspondence between login information, voiceprint information, operation commands, and authorized users. This user-authority correspondence table TB is stored in the storage device 50 as a database.

  The authorized person is a person who has the authority to use the analyzer 2. In this example, a user A who is an apparatus administrator, a user B who is an analysis supervisor, and a user C who is an operator are authorized users of the analysis apparatus 2. The login information includes, for example, a login ID (identifier) and a login password. In this example, login information LA is assigned to user A, login information LB is assigned to user B, and login information LC is assigned to user C.

  The voiceprint information is information for specifying the voiceprint of each authorized user. The voiceprint information of user A is VA, the voiceprint information of user B is VB, and the voiceprint information of user C is VC. A voice print pattern of each authorized user is stored in the storage device 50. The voice print pattern stored in the storage device 50 can be acquired using the voice print information.

  The operation command is a command for instructing the operation of the analyzer 2. In this example, as operation commands, an operation command C1 for instructing activation of the analysis apparatus 2, an operation command C2 for instructing stop of the analysis apparatus 2, an operation command C3 for instructing execution of analysis by the analysis apparatus 2, and an analysis apparatus 2 There are prepared an operation command C4 for instructing a parameter change, an operation command C5 for instructing a temporary stop of analysis by the analyzer 2, and an operation command C6 for instructing to stop the analysis by the analyzer 2.

  In detail, the operation authority by the operation command C1 is an authority for starting the analysis apparatus 2 from a stop (sleep) state. The operation authority by the operation command C2 is an authority for putting the analyzer 2 in operation into a stop state. In order to ensure failure prevention, stability, and performance of the analyzer 2, it is necessary to start and stop the analyzer 2 under appropriate conditions. Therefore, the operation authority by the operation commands C1 and C2 is given only to the device administrator. Is done.

  The operation authority by the operation command C3 is an authority to execute the analysis, and is given to the device manager, the analysis manager, and the operator. The operation authority by the operation command C4 is an authority to temporarily change the parameters of the analyzer 2 (for example, the flow rate of the liquid feed pump) during analysis or during preparation for analysis. In an environment where the inspection process is strictly managed, the operation authority by the operation command C4 may be invalidated. An operator who performs analysis outside strict management is appropriately given an operation authority by the operation command C4 in consideration of convenience.

  The operation authority by the operation command C5 is an authority to pause the analysis under analysis, and the operation authority by the operation command C6 is an authority to cancel the analysis under analysis. The operation authority by the operation commands C5 and C6 is given only to a specific person in charge such as an apparatus manager and an analysis person in charge for the purpose of preventing the planned analysis from being canceled without any reason.

  The user-authority correspondence table TB includes operation authority information indicating the presence / absence of operation authority by each operation command for each authorized user. In FIG. 2, “O” indicates that the user has the operation authority, and “X” indicates that the user does not have the operation authority. User A has an operation authority for all operations by the operation commands C1 to C6. User B has the operation authority for the operation by the operation commands C3 to C6. User C has an operation authority only for the operation by the operation command C3.

(3) Control Program FIGS. 3 and 4 are flowcharts showing the algorithm of the control program of the control system 1. First, the use authority determination unit 11 in FIG. 1 determines whether or not login information is input by the information input unit 10 (step S1). When the login information is input, the table acquisition unit 14 acquires the user-authority correspondence table TB stored in the storage device 50 (step S2). The use authority determining unit 11 determines whether or not the input login information matches the login information of the use authority based on the user-authority correspondence table TB (step S3).

  If the input login information does not match the login information of the authorized user, the authorized authority determining unit 11 notifies the person who has entered the login information that there is no authorized usage (step S15). Specifically, the usage authority determination unit 11 causes the display unit 30 to display that the person who has input the login information does not have the usage authority. In the example of FIG. 2, when login information other than the login information LA, LB, LC is input, it is notified that there is no use authority. Thereafter, the processing of the control program returns to step S1.

  When the login information input in step S3 matches the login information of the authorized user, the authorized authority determining unit 11 sets the control program of the control system 1 to the logged-in state (step S4). For example, when any of the login information LA, LB, and LC is input, the control program is set to the login state. Further, the use authority determining unit 11 specifies a login user based on the user-authority correspondence table TB (step S5). For example, when the login information LA is input, the user A is specified as the login user.

  Next, the voice recognition unit 12 determines whether or not voice is input as a voice signal by the voice input unit 20 (step S6). When a voice signal is input, the voice recognition unit 12 detects an operation command and a voiceprint from the input voice signal using a voice recognition function (step S7). For example, when a voice signal based on the voice “activation of the analyzer” is input, the operation command C1 is detected from the voice signal and a voiceprint is detected.

  The voiceprint determination unit 15 collates the voiceprint (speaker's voiceprint) detected by the voice recognition unit 12 with the logged-in user's voiceprint based on the user-authority correspondence table TB (step S8). It is determined whether or not the login user's voiceprint matches (step S9).

  If the voiceprint of the speaker does not match the voiceprint of the logged-in user, it is notified that the speaker is not a logged-in user (step S16). Specifically, the voiceprint determination unit 15 causes the display unit 30 to display that the speaker is not a login user. For example, when the login user is the user A and a person other than the user A speaks, it is notified that the speaker is not the login user. Thereafter, the process of the control program returns to step S6.

  If the voiceprint of the speaker and the voiceprint of the logged-in user match in step S9, the operation authority determining unit 13 operates the operation command in which the logged-in user is detected by the voice recognition unit 12 based on the user-authority correspondence table TB. It is determined whether or not the user has the operation authority (step S10). For example, when the logged-in user is the user A and the user A utters the operation command C1, the presence / absence of the operation authority for the user A by the operation command C1 is determined. Further, when the logged-in user is the user B and the user B makes an utterance that means the operation command C1, it is determined whether the user B has the operation authority by the operation command C1.

  When the logged-in user does not have the operation authority based on the operation command detected by the voice recognition unit 12, the operation authority determination unit 13 notifies the logged-in user that there is no operation authority (step S17). Specifically, the operation authority determination unit 13 causes the display unit 30 to display that the login user does not have the operation authority. For example, when the logged-in user is the user B and the user B makes an utterance that means the operation command C1, the user B is notified that there is no operation authority. Thereafter, the process of the control program returns to step S6.

  When the logged-in user has an operation authority based on the operation command detected by the voice recognition unit 12 in step S10, the operation command supply unit 16 gives the operation command to the analyzer 2 (step S11). Thereby, an operation based on the operation command is executed in the analysis apparatus 2. For example, when the logged-in user is the user A and the user A utters the operation command C1, the operation command C1 is given to the analysis device 2. The analyzer 2 is activated based on the operation command C1.

  At this time, the operation log recording unit 17 identifies the person (login user) who has instructed the operation by the operation command, the operation information indicating the operation content by the operation command given to the analyzer 2, and the time indicating the operation time. Information is recorded in the operation log LG (step S12). For example, the identification information of the user A is recorded in the operation log LG as the person who has instructed the operation by the operation command C1, and “activation of the analyzer” is recorded together with the operation command C1 as the operation content by the operation command C1. “October 0 day o hour o min” is recorded.

  Thereafter, the use authority determination unit 11 determines whether or not a logout instruction is input by the information input unit 10 (step S13). When a logout instruction is input, the use authority determining unit 11 places the control program of the control system 1 in a logout state (step S14). Thereafter, the processing of the control program returns to step S1. If no logout instruction is input in step S13, the control program process returns to step S6.

  FIG. 5 is a diagram showing an example of the operation log. In FIG. 5, the operation log LG includes time information, login user identification information, operation commands, and operation contents. According to the example in FIG. 5, the user A who is an apparatus administrator instructs the activation of the analyzer by the operation command C1, the user B who is the person in charge of analysis instructs the change of parameters, and the user C who is the operator performs analysis. It can be seen that the execution is instructed. Thereafter, it can be seen that the user B instructs the suspension of the analysis, the user B instructs the change of the parameter, the user C instructs the execution of the analysis, and the user A instructs the stop of the analyzer. In this way, traceability of the analysis result is ensured by the operation log LG.

(4) Effects of the Embodiment According to the analysis system 100 including the control system 1 according to the present embodiment, an operation command and a voiceprint are detected from an audio signal based on the voice of the speaker after login authentication. An operation command is given to the analysis device 2 when the voiceprint of the speaker matches the voiceprint of the logged-in user and the logged-in user has operation authority based on the operation command. Therefore, it becomes impossible for a person other than the logged-in user to operate the analyzer 2 by voice. In addition, even a logged-in user cannot perform an operation without operating authority. In this case, after the login authentication, the user can instruct the operation of the analyzer 2 by voice without performing the work of removing the protective gloves. Therefore, the convenience of the operation by the person having the operation authority for each operation content is improved, and the operation by the person who does not have the operation authority is surely prohibited.

  In addition, since the operation log LG is automatically recorded, it is possible to easily recognize the operation content, the operator, and the operation time of the analysis device 2. Thereby, traceability of analysis is ensured.

(5) Other Embodiments The analyzer 2 in the analysis system 100 according to the above embodiment is not limited to a liquid chromatograph or a gas chromatograph, but is an analyzer using X-rays, an analyzer using electron beams, and an electromagnetic wave. Other analyzers such as analyzers using mass spectrometers, analyzers using thermal analysis, analyzers using electrochemical methods, analyzers using nuclear magnetic resonance, electron microscopes, etc. .

  In the above embodiment, login authentication is performed by the user inputting login information. However, the login authentication method is not limited to this. As login authentication, biometric authentication such as voiceprint authentication, fingerprint authentication, face authentication, iris authentication, and voice authentication may be used.

  Further, the control system 1 is not limited to a personal computer, and may be configured by installing a control program in a mobile terminal device such as a smart device having a touch panel and a voice input function. Further, the control system 1 may be built in the analysis device 2.

  The identification information of the operation log LG may be the name of the person who instructed the operation or the login information of the person who performed the operation. Further, the operation information of the operation log LG may include only the operation command, or may include only information indicating the operation content by the operation command.

  The control program of the control system 1 may be downloaded from a server connected to the Internet and stored in the storage device 50, for example.
