Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a network-compatible measuring apparatus, and more particularly to improvement of a login function in a measuring apparatus such as a recorder that records digitized measurement data on a storage medium.
[Prior art]
[0002]
A recorder, which is a type of measuring device, is also used for monitoring manufacturing processes of pharmaceuticals, for example. Depending on the usage pattern in the monitoring of the manufacturing process of pharmaceuticals, etc., as shown in FIG. 4, a personal computer PC and a plurality of recorders R are connected via a LAN, and the measurement conditions of each recorder R are set to the personal computer PC. The measurement data is also read into the personal computer PC.
[0003]
Incidentally, some network-compatible measuring apparatuses are provided with a login function so that only a specific registered user can operate from the viewpoint of ensuring the security of the measurement system.
[0004]
FIG. 5 is a block diagram showing an example of such a conventional network-compatible measuring apparatus, and shows an example of a recorder. Prior to the operation of the recorder, user information including a user name, a user ID, and a password for giving authority to log in to the recorder is set using the setting data operation unit 1. This setting data is stored in the setting data area of the internal memory 3 via the arithmetic control unit 2. Note that, as these setting data, a user list having an operation authority from the key login operation unit 4 and a user list having an operation authority from the communication login operation unit 5 are individually stored.
[0005]
When the user performs a login operation from the key login operation unit 4, the arithmetic control unit 2 performs a key login operation in which the user name, user ID, and password input by the key login operation unit 4 are stored in the internal memory 3. It is confirmed whether or not the user name, user ID, and password registered in the user list having the operation authority from the unit 4 match. The arithmetic control unit 2 also confirms that there is no user who is currently key-logged in based on the key login status data stored in another area of the internal memory 3. When the user name, the user ID, and the password match and there is no user who is currently logged in with the key, the user is permitted to log in with the key, and operations such as setting the measurement conditions of the recorder become possible. In logout state, operations other than logging in can be performed.
[0006]
When the user logs in using the communication login operation unit 5, the arithmetic control unit 2 stores the user name, user ID, and password input by the communication login operation unit 5 in the internal memory 3. It is confirmed whether the user name, user ID, and password registered in the user list having the operation authority from the communication login operation unit 5 match. The arithmetic control unit 2 also confirms that there is no user who is currently logged in through communication login status data stored in another area of the internal memory 3. If the user name, the user ID, and the password match and there is no user who is currently logged in via communication, the user is permitted to log in via communication, and operations such as setting measurement conditions for the recorder become possible. In logout state, operations other than logging in can be performed.
[0007]
When measurement is started through these series of login procedures, an input signal such as a voltage applied to the input terminal 6 is converted into digital data by the measurement circuit 7, and these digital data are set in advance via the arithmetic control unit 2. It is stored in the measurement data area of the internal memory 3 as measurement data from the memory start to the memory stop at the cycle.
[0008]
The measurement data stored in the internal memory 3 is transferred and stored in the storage medium 8 in a file format when the memory is stopped. In addition to the measurement data, the storage medium 8 also stores information for displaying the waveform of the measurement data, and information on alarms and messages generated during the measurement. After the file is saved, the measurement data file is read from the storage medium 8 and the measurement data is referred to by the display means 9.
[0009]
However, in the conventional measuring apparatus, the management of the key login and the communication login is performed independently and individually. Thereby, it is possible to log in from the communication login operation unit 5 / key login operation unit 4 regardless of the login / logout state from the key login operation unit 4 / communication login operation unit 5, and to set the measurement device and read out measurement data. Was possible.
[0010]
Although the management of the key login and the communication login is performed individually and independently in this way, there is an advantage that the setting and operation of the measurement device can be performed substantially simultaneously, but the user who can set and operate the measurement device can simultaneously There will be more than one.
[0011]
[Problems to be solved by the invention]
However, the presence of a plurality of users who can set and operate the measuring device at the same time has a problem that it does not conform to the audit trail described below.
[0012]
In other words, the measurement results of the recorder used for monitoring the manufacturing process of pharmaceuticals and the like are required to have reliability for responding to inspections by public institutions. Specific examples include the restriction of access to measurement results requested by the US Food and Drug Administration for audits to pharmaceutical manufacturers, the storage of operation histories, and the writing of signatures during data authentication. These are called audit trails. .
[0013]
Therefore, in order to adapt to the audit trail, it is possible to disable only the communication login function by enabling only the key login function. The degree of freedom is greatly limited.
[0014]
The present invention has been made to solve such problems, and it is an object of the present invention to provide a network-compatible measuring apparatus that improves operability and allows the recorded results to be handled as formal data that conforms to an audit trail. .

[0023]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing an embodiment of the present invention, and the same reference numerals are given to portions common to FIG. 1 and 5 differ in the data storage form in the internal memory 3 and the configuration of the login operation unit 10.
[0024]
In other words, in the internal memory 3, the login user list area is stored in a centralized manner without being divided into key login and communication login. Further, the login control data area stores the key login status data and the communication login status data in a unified manner as shown in FIG.
[0025]
The login operation unit 10 is also shared without being separated into the key login operation unit 4 and the communication login operation unit 5 as shown in FIG. 5, and the key input unit 11 and the communication input unit 12 are individually provided as input units.
[0026]
In such a configuration, user information that gives authority to log in to the measuring apparatus (recorder in the example of FIG. 1) is input from the setting data operation unit 1, and the login user list in the internal memory 3 and Save in the login control list area. The stored contents include a login method, a user name, a user ID and password, an operable range, and the like. Depending on the login method, it is possible to set, for each user, a method in which login is not possible, only from the key, only from communication, and login from the key and communication.
[0027]
When logging in, a user name, a user ID, and a password are input to the calculation control unit 2 from the key input unit 11 or the communication input unit 12 of the main body via the login operation unit 10. The arithmetic control unit 2 confirms whether the input user name, user ID, and password match the user name, user ID, and password stored in the login control data area, or whether the user has already logged in. . If the user name, user ID, and password match, and the user is not logged in, the logged-in data is saved in the login control data area, and the entered user is logged in, allowing the recorder to be set up and operated. become.
[0028]
Here, when logging in from the communication input unit 12, it is possible to select a “setting connection” that can be set and operated and a “monitor connection” that can read only measured value data.
[0029]
Further, when there is a user who has logged in from the key input unit 11, login by communication setting connection is prohibited, and control is performed so as to limit the users who can set the recorder.
[0030]
Further, when there is a user who is logged in through the setting connection from the communication input unit 12, control is performed so that no user can log in from the key input unit 11.
[0031]
Further, when logging in from the communication input unit 12 through monitor connection, control is performed so that even if there is a user logged in through setting connection from the key input unit 11 and the communication input unit 12 unless they are the same user. As a result, measurement data can be constantly monitored as required.
[0032]
In the operation history data area, information for distinguishing whether the login is performed from the key input unit 11 or the communication input unit 11 is recorded in addition to the operation content, the date and time, and the operated user name.
[0033]
In the logout state, control is performed so that operations other than the login operation can be performed as in the conventional case.
[0034]
As a result, the number of users who can operate the recorder can be restricted, and the user who is operating the recorder can be specified, thereby ensuring the security of the recorder.
[0035]
When measurement is started through these series of login procedures, an input signal such as a voltage applied to the input terminal 6 is converted into digital data by the measurement circuit 7, and these digital data are set in advance via the arithmetic control unit 2. It is stored in the measurement data area of the internal memory 3 as measurement data from the memory start to the memory stop at the cycle.
[0036]
The measurement data stored in the internal memory 3 is transferred and stored in the storage medium 8 in a file format when the memory is stopped. In addition to the measurement data, the storage medium 8 includes information for displaying the waveform of the measurement data, information on alarms and messages generated during the measurement, and information on who made the memory start and memory stop. Is also stored.
[0037]
By adding the user information to the measurement data in this way, only the registered user can be given the right to access the data.
[0038]
In addition, by saving the operation history, it is possible to leave evidence about who, what, and what during the measurement.
[0039]
It should be noted that the contents of the save file may be saved together as one file, or may be saved individually in a file format corresponding to the measurement data file.
[0040]
After the file is saved, the measurement data file is read from the storage medium 8 and the measurement data is referenced on the display unit 9.
[0041]
FIG. 2 is a block diagram showing another embodiment of the present invention, and shows an example in which a signature is input from the signature input unit 13 as data authentication. When the sign input is performed, the sign information is added to the file read via the arithmetic control unit 2 and stored in the storage medium 8. The details of the sign information are the name of the signed user, time, determination of availability of measurement data, comments, and the like.
[0042]
In addition, by giving multiple users signature input and limiting the priority order of the signature input, for example, after the operator's signature input, the administrator can input the signature, and thorough data management can be achieved. .
[0043]
With the above, it is possible to realize a recorder that supports access restriction, operation history storage, signature writing, etc. for digitized data, and can receive the same treatment as measurement recording recorded with a conventional chart recorder did.
[0044]
Further, by providing the storage medium outside the apparatus, the measurement data can be read out and input by another apparatus such as a personal computer. At that time, by using the user information stored in the external storage medium, it is possible to permit only the user registered in the recorder to access the measurement data.
[0045]
Furthermore, data tampering can be prevented by making the data binary, and data tampering can be prevented by storing check information for detecting tampering of data and sharing the data tampering detection method between the recorder and the personal computer. It can also be detectable.
[0046]
FIG. 3 is a flowchart showing an example of a procedure for opening a file and inputting a signature on a personal computer. A description will be given according to the processing procedure of this flowchart.
(S1) A user name is input.
(S2) It is determined whether the user name is registered in the file.
(S3) If the determination in S2 is “Yes”, the user ID and password are entered. If the determination in S2 is “No”, the process ends.
(S4) It is determined whether the user ID and password are correct.
(S5) If the determination in S5 is “Yes”, the file is opened. If the determination in S5 is “No”, the user ID and password are re-input.
(S6) Sign input is performed.
[0047]
In the present invention, portability of measurement data can be realized by providing a storage medium outside the apparatus.
As a result, it is possible to realize excellent operability such that a digital signature can be performed after the measurement data is confirmed by another device at a place away from the measurement site.
[0048]
Note that the recorder of the present embodiment may record measurement data not only for the pharmaceutical industry but also for public authentication in other industries.
[0049]
Further, the remote control operation by the remote control terminal occurs and operates even when not logged in to the measuring apparatus. In a conventional apparatus, the operation history records the state at that time (user information when logged in, unknown when not logged in).
[0050]
On the other hand, by adding a mode that allows remote control operation only when the user is logged in to the measurement device, it is necessary to log in to the measurement device body when performing remote operation, and record it in the measurement device. Remote operation audit trail based on the operation history to be performed.
Note that operation method (key, communication, remote) information is stored in the operation history, so that the operation method can be distinguished.
[0051]
In the above embodiment, an example in which the measurement apparatus is a recorder has been described. However, the present invention is not limited to a recorder, and the present invention can be applied to any apparatus that records measurement results as electronic data, such as a data logger.
[0052]
【The invention's effect】
As described above, according to the present invention, it is possible to realize a network-compatible measuring apparatus that improves operability and can handle the recorded result as formal data that conforms to the audit trail. For example, the US Food and Drug Administration audits in the pharmaceutical industry. Can also be supported.
