Description

  The present invention relates to a facility management apparatus and a facility management method.

  In the manufacturing facility or service industry, continuous maintenance activities to maintain the performance, function and safety of the product or service provided (hereinafter referred to as “maintenance activities” refers to the performance and functional safety of the product or service provided. Means an activity to maintain

  In particular, careful attention must be paid to eliminating all possible impediments to maintenance activities when the products or services provided affect human life and social life.

  Various countermeasures have been taken with respect to these countermeasures. For example, ISO 9000 series quality management system requirements, which are international standards, have been issued.

  In order to ensure the safety of the maintenance activity, a technique for authenticating using the characteristics of the living body is known.

  Such a technique is described in, for example, JP-A-2005-71118.

  As a result of analyzing problems related to the performance, function, and safety of conventional products and services while referring to the technology described in Japanese Patent Application Laid-Open No. 2005-71118, those problem factors can be roughly classified into three types. I understood.

JP 2005-71118 A

  These three types of problem factors are 1 for human factors, 2 for facilities and services themselves (mechanical, electrical, other physical factors and logical factors such as program errors), and 3 for Inconsistency with environment and rules.

  It is an object of the present invention to provide a facility capable of maintaining maintenance activities with minimal influence on human factors, factors of the facilities and services themselves, and hindering factors such as environmental and rule factors. A management apparatus and a management method for equipment are provided.

  In order to achieve the above object, according to the present invention, individual authentication is performed by collating identification information of an individual ("individual" includes not only a living body such as a person and an animal but also an object and a moving system), and Maintenance activity that determines authority from information, receives maintenance activity information related to maintenance activity for the equipment for which maintenance activity is permitted based on the individual authentication and authority determination, and defines allowable maintenance activity according to maintenance activity conditions A maintenance activity consistency is read out from the maintenance activity rule storage unit storing the rules, and the maintenance activity consistency is logically calculated by comparing the received maintenance activity information with the allowable maintenance activities read from the maintenance activity rules. Configured.

  Specifically, in order to eliminate human factors, those who perform maintenance actions (hereinafter, those who perform maintenance actions are not only “humans” but also “robots”, “dedicated maintenance reception devices”, “remote operation” (Remote operation) maintenance management function etc. ”) is authenticated to have appropriate authority (qualification). Also, the person who authenticates the person, records the result of inspection and repair work to prove that the inspection and repair work of the equipment and service itself is appropriate, and the rules applied to the environment of the equipment and equipment And certify the consistency of maintenance activities.

  In addition, if regular maintenance activities are required, alerts will be given in advance.

  Furthermore, in preparation for the case where an organization other than the manager of the manufacturing facility and the service providing facility performs the maintenance activities independently, the maintenance work is requested and accepted, and the costs associated with the activities are charged.

  According to the present invention, it is possible to perform continuous facility or service maintenance activities with reduced influence on human factors, factors of facilities and services themselves, and obstruction factors such as environmental and rule factors.

  In addition, it is possible to eliminate problems caused by human factors, problems caused by the factors of the equipment and services themselves, and environment such as manufacturing environment and service environment, which may occur when maintaining manufacturing equipment and service providing equipment. Eliminating inconsistencies between these rules and maintenance activities can be implemented comprehensively and systematically, and as a result, the level of performance, function, and safety of products or services that can be provided from manufacturing facilities or service providing facilities can be maintained.

  In addition, when a regular maintenance activity is required, alerting in advance can prevent the most nasty and basic error that the maintenance activity itself is not performed.

  Furthermore, it is possible for an organization other than the manager of the production facility and the service providing facility to carry out the maintenance activities independently, and the maintenance activities can be made more fair.

  Hereinafter, examples for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory diagram showing a maintenance method for manufacturing facilities and service providing facilities. FIG. 2 is an image diagram showing a configuration of an operation authority authentication system that performs personal authentication and authority authentication in the present invention. FIG. 3 shows an example of recorded contents of authority information indicating which equipment can be maintained by an operator.

  Hereinafter, taking FIG. 3 as an example, the operation for determining the presence / absence of authority in the case where an operator performs maintenance work on equipment will be described. This company has three workers (A, B, and C) and three facilities (X, Y, and Z), and the facilities that each worker can perform maintenance work are determined.

In FIG. 1, an arithmetic processing unit (not shown) performs operations of the flowcharts (S31 to S34) according to the biological information storage unit 110, authority information storage unit 120, equipment environment, application rule storage unit 130, and maintenance work execution information. The process is executed with reference to the storage contents of the storage unit 140.

  First, the flow of work when the worker A performs maintenance work on the equipment X will be described with reference to FIG.

(Business flow)
The worker performs personal authentication using the biometric information storage unit 110 registered in advance. When the worker A is specified, it is confirmed using the authority information storage unit 120 that there is a maintenance work authority for the equipment X (S31). When the operation to the target facility becomes possible and the maintenance work for the facility X is performed by the worker A, the execution information is received and stored in the corresponding storage unit (S32).

  Consistency of the result of the maintenance work performed by the worker is authenticated by the equipment environment, the equipment environment applied to the equipment, and the application rule storage unit 130 (S33).

  Further, the maintenance work performed by the worker is recorded as the maintenance work execution information storage unit 140 (S34).

(Operation authority authentication system)

FIG. FIG. 2 will be used to explain the details of the operation authority authentication system that permits the facility maintenance work to be performed by the personal authentication and authority authentication. As shown in FIG. 2, the operation authority authentication includes an authentication device 100, an operation key device 200, and a biological information sensor (finger vein sensor) 400 that is a biological information sensor. Note that, when the maintenance authority for the operator's target facility is authenticated by the operation authority authentication system, the operation prohibition state of the maintenance target facility 300 is released and the maintenance operation can be performed. .

  The authentication device 100 is, for example, an IC card that is carried by each worker, and records a biometric information storage unit 110 that stores a biometric information template (hereinafter referred to as “finger vein template”) and equipment that allows the worker to perform maintenance work. It includes an authority information storage unit 120, a personal authentication unit 160 as an arithmetic function, an authority authentication unit 170, and a communication processing unit 180 that transmits and receives information to and from the operation key device 200.

  The biometric information storage unit 110 stores a finger vein template for collation with the finger vein data of the worker. For example, as shown in FIG. 3, the authority information storage unit 120 stores authority information that the operator A can perform maintenance work with X and Y, and Z cannot be performed.

  The personal authentication unit 160 includes a result determination unit 161, and collates the finger vein information of the worker image-processed by the preprocessing unit 210 of the operation key device 200 with the finger vein template stored in the biometric information storage unit 110. The user authentication is performed, and the authority authentication unit 170 is instructed based on the authentication result.

  The authority authentication unit 170 includes an authority determination unit 171 and is stored in the worker information authenticated by the principal authentication unit 160, the facility information of the facility information transmission unit 220 of the operation key device 200, and the authority information storage unit 120. Based on the authority information, it has a function of determining whether the operator can perform maintenance work on the equipment and transmitting the determination result to the operation canceling unit 230 of the operation key device 200.

The operation key device 200 is, for example, a device provided on an operation panel of the facility, and transmits and receives information between the preprocessing unit 210, the facility information transmission unit 220, the operation release unit 230, and the authentication device 100. And a communication processing unit 280 to perform.

  The pre-processing unit 210 has a function of processing finger vein information (finger vein image) acquired from the biological information sensor (finger vein sensor) 400 and transmitting the processing information to the personal authentication unit 160.

  The facility information transmission unit 220 has a function of transmitting facility information determined by authority authentication to the authority authentication unit 170.

  The operation canceling unit 230 has a function of receiving the authority determination result transmitted from the authority authenticating unit 170 and instructing the maintenance target facility 300 to operate if the maintenance work can be performed.

  Information exchange between the authentication device 100 and the operation key device 200 is performed via the communication processing units 180 and 280, and is performed wirelessly such as Bluetooth.

(Operation of the operation authority authentication system)
FIG. 3 shows the stored contents of the authority information storage unit 120 of FIG. With respect to this authority information storage unit 120, an operation authority authentication operation will be described by taking as an example the case where the workers A and B perform maintenance work on the equipment X.

  The worker A possesses the authentication device 100, and performs biometric authentication by holding a finger over the biometric information sensor (finger vein sensor) 400 of the operation key device 200 incorporated in the operation panel of the equipment X to be maintained. The finger vein data of the worker A is image-processed by the pre-processing unit 210, and the personal authentication is performed by collating the finger vein template registered in advance in the biometric information storage unit 110 by the personal authentication unit 160. The facilities that can be maintained by the authenticated worker A are the facilities X and Y based on the authority information registered in advance in the authority information storage unit 120. The authority authentication unit 170 determines that the operator A can work on the facility X. (Indicated by “◯” in FIG. 3). The determination result is transmitted to the operation canceling unit 230, and the operation key device 200 cancels the prohibition of the operation of the equipment X, so that the maintenance work of the worker A can be performed.

  On the other hand, when the worker B performs the maintenance work for the equipment X in the same manner, the authority authentication unit 170 determines that the work cannot be performed because the worker B does not have the maintenance work authority for the equipment X. Therefore, the prohibition on the operation of the equipment X is not lifted, and the worker B cannot perform the maintenance work on the equipment X (indicated by “x” in FIG. 3).

  As described above, the operation authority authentication system is an example in which a worker of a certain company holds an IC card as an authentication device and authenticates whether or not maintenance work can be performed on a facility provided with an operation key device having a finger vein sensor on an operation panel. Explained. In this system, since personal authentication is performed by biometric authentication, it is possible to prevent an unauthorized worker or an unregistered worker from impersonating an authorized worker.

Here, in the first embodiment, the finger vein is used as the biometric information. However, the biometric information is not limited to the finger vein, and other biometric information, for example, palm vein, fingerprint, iris, voiceprint, face type. ,
Information such as DNA (Deoxyribonucleic Acid: gene information) that can identify an individual may be used. For example, iris information may be recorded in the biological information storage unit 110 and the biological information sensor (finger vein sensor) 400 may be a camera.

  The authentication device 100 is not limited to an IC card, and may be a computer system such as a personal computer connected to the operation key device 200 via a LAN (wired or wireless), a computer system incorporated in the facility itself, or the like. Further, the communication means of the authentication device 100 and the operation key device 200 is not limited.

  The operation key device 200 is not limited to be provided on the operation panel of the facility, but may be any device connected to the target facility.

  The method by which the operation key device 200 prohibits the operation is not particularly limited, and for example, physical operation availability by locking / unlocking the operation panel or logical operation availability by changing the operation panel menu may be used. .

  In the first embodiment, the authority information storage unit 120 has a relationship between the worker and the facility. However, the authority information storage unit 120 is not particularly limited to this. For the worker, the attribute value of the worker (for example, presence or absence of specific qualification, position) , Affiliation, years of experience, etc.). Similarly, an equipment may be determined for an attribute value (for example, type, type, installation location, etc.) of the equipment.
