Description

  The present invention relates to an equipment management system in a manufacturing plant, and more particularly to a system for managing plant equipment using a so-called RFID tag.

  In general, when each equipment installed in a manufacturing plant is maintained, if the scale of the plant is small, the information required for equipment maintenance is recorded in a ledger stored by the factory management department and managed as paper information. ing.

  In addition, when the scale of the plant is large, the information necessary for maintenance of the equipment is, for example, a server storing management information and a portable port that can be accessed by each worker through a wireless LAN. A management system is configured with the terminal, and the worker holds the portable terminal and goes to the facility or apparatus, and inputs management information unique to the facility necessary for managing the facility or apparatus to the portable terminal. The factory is configured to store and transfer the data stored in the mobile terminal after the completion of all work or after the maintenance work to the server via the wireless LAN, and manage all information by the electronic file of the server Has been.

  Therefore, in such a conventional facility management system, a wired LAN network or a wireless LAN network is installed in almost the entire area of the factory or plant, and a database server is connected to the wireless LAN network, so that each site Since it is necessary to configure so that the database server can be accessed from, the scale of the entire management system becomes large and the equipment cost increases.

  In addition, as described above, management information of conventional factories, plant facilities or equipment is centrally managed in electronic files such as paper ledgers or servers, separately from the equipment, equipment and facilities on site. Therefore, when maintenance and maintenance of facilities and equipment, each worker uses and refers to management information. In the case of a paper ledger, always go to the factory management department and check the management ledger stored by the management department. If it is necessary and managed in the electronic file of the server, it is necessary to access the electronic file of the server each time using the portable terminal. For this, it is complicated to confirm and acquire information necessary for maintenance.

Therefore, it is not necessary to go to the management department and check the paper ledger every time when checking the management information of each equipment and device at the site. There is a need for an equipment management system that does not require access and that can reduce equipment costs for storing management information.
In addition, a plurality of maintenance workers are working at the plant work site. In particular, a certain worker performs maintenance work on a predetermined valve device at a liquid product (especially food, milk, dairy product) production site. When the operation is started, it is necessary for the same worker to complete the maintenance work from the viewpoint of safety of the maintenance work.
For example, it may be assumed that a certain worker starts a maintenance work on a certain valve device and leaves the site temporarily due to the circumstances of the worker. In such a case, another worker determines that the maintenance work of the valve device has been completed, and the valve device in which the maintenance work has not been completed is actually moved to another department for use. There is a possibility. In such a case, the above-mentioned valve device that has not undergone maintenance work will continue to be used as it is, and in the production site of liquid products (especially food, milk, dairy products), it was considered from a hygienic viewpoint. If this is the case, it will be extremely inappropriate.

As a result of investigating the prior art from this point of view, for example, as described below, RFID tags (so-called IC tags) are used to manage various products, manage various equipment, or manage plant facilities. Techniques to do this have been proposed.

  The above Patent Document 1 relates to a “plant information collection system”, and conventionally, purchase history, operation history, maintenance history, design drawings showing installation locations of plant facilities where trouble has occurred, and different departments in different databases. In many cases, different persons in charge manage information, and there is a problem that it takes time to search for information. Therefore, an IC tag having a wireless function is attached to each facility of the plant and management information such as maintenance history is provided. The management information stored in the IC tag is read out by the IC tag reader having a wireless function, and is communicated with the information processing apparatus via the network from the wireless access point, and the information is obtained by the search logic based on the information acquired by the reader terminal. A system for searching a database included in a processing apparatus and collecting related information is disclosed.

  The above Patent Document 2 relates to “inspection history management device and RFID tag”, attaches an RFID tag to a device that requires periodic inspection used in a nuclear power plant, reads the device attribute data of the RFID tag with a reader when necessary, A system is disclosed in which the data is given to a device management terminal, and the device management terminal is configured to manage inspection times, inspection contents, and the like of a plurality of devices based on device attribute data.

  The above Patent Document 3 relates to a “support system and equipment unit”, and relates to a management system for a gas manufacturing plant and a city gas supply equipment network. In view of the enormous amount of man-hours required for maintenance and management, an IC tag is attached to a representative equipment member, and inspection information, maintenance information, etc. relating to the equipment member are stored, and when necessary, the information is stored via a handy computer. A system is disclosed that is configured to obtain and rewrite management information of a management terminal in which management information is stored.

  Patent Document 4 relates to “a maintenance system, a maintenance support terminal, an RFID tag, a product maintenance method, and a maintenance support program”, and requires maintenance such as inspection and repair after delivery to a customer as a product user. An IC tag storing maintenance information is attached to a product to be maintained, and maintenance information is stored in a database according to the importance level via an electronic terminal equipped with a reader / writer function, and the maintenance history is updated. A system configured as described above is disclosed. .

  In such conventional techniques, all of the information stored in the IC tag is read by a reader, and the read information is centrally managed by a management computer. A network such as a LAN is required between the reader and the database server, the entire system becomes large, and the cost of the system configuration increases.

Therefore, the first problem of the present invention is that the cost required for the system configuration can be reduced, and maintenance can be performed quickly and easily without accessing the information management device that is the core of the management system at the time of maintenance. An object of the present invention is to provide an equipment management system in a manufacturing plant capable of acquiring information.
Furthermore, the second problem of the present invention is that a certain worker starts a maintenance work on a certain valve device at a manufacturing site of a liquid product (especially food, milk, dairy product), and temporarily depends on the circumstances of the worker. After leaving the site, other workers actually move the valve device, which has not been completed, to other departments and continue to use it. An object of the present invention is to provide an equipment management system that can avoid a serious situation.

In order to solve such a technical problem, the invention according to claim 1 is an equipment management system in a manufacturing plant, which is attached to each equipment of the manufacturing plant and stores information on each equipment. and tags, is constituted by the above-described RFID tag information read / writable portable terminal, information on each facility, both when it is managed only by the RFID tag, the mobile terminal, the RFID tag via radio waves The stored information is formed to be readable / writable, and when the RFID tag is accessed, it is configured to be able to read / write information by acquiring a unique flag register transmitted by the RFID tag. And

Therefore, in the invention described in claim 1, the management system can be formed only by each facility constituting the manufacturing plant, the RFID tag mounted on each device, and the portable terminal. An information management device such as a database for centrally managing information and a wireless LAN facility for accessing the database server from a portable terminal are not required.
Further, since the portable terminal is formed so as to be able to read / write (read / write) information stored in the RFID tag by radio waves, the so-called “electromagnetic induction method” is used in the invention according to claim 1. Instead, based on the “radio wave system”, the radio wave emitted from the portable terminal is received by the antenna of the RFID tag to transmit information. Therefore, the worker can acquire information stored in the RFID tag from a farther position than the “electromagnetic induction method”.
The portable terminal is configured to be able to read / write (read / write) information by obtaining a unique flag register transmitted by the RFID tag when accessing the RFID tag.

  In the invention described in claim 2, the information includes history information as a result of occasional maintenance work related to each facility. Therefore, in the invention described in claim 2, since the history information of maintenance related to each facility is stored in the RFID tag, the history information can be acquired by the portable terminal.

  In the invention described in claim 3, the information includes history information of a result of occasional use regarding each facility. Therefore, in the invention described in claim 3, since the history information on the use related to each facility is stored in the RFID tag, the history information can be acquired by the portable terminal.

  According to a fourth aspect of the present invention, the facility is a valve device that is disposed in a pipeline for manufacturing a fluid product and can control the opening and closing of the pipeline.

  According to a fifth aspect of the present invention, the RFID tag is mounted on an air motor unit that can open and close the valve body.

  The invention described in claim 6 is characterized in that the information is a use management manual for each device.

  The invention according to claim 7 is characterized in that the information is character information.

  The invention according to claim 8 is characterized in that the information is image information. In this case, the image information includes still image information and moving image information.

  The invention according to claim 9 is characterized in that the information is image information indicating an environment in the plant where the valve device is used. Therefore, the operator can acquire the environment where the specific valve device is used from the RFID tag by the image.

The invention according to claim 10 is characterized in that the RFID tag is a passive tag. Therefore, in the invention described in claim 11, since the RFID tag is constituted by a passive tag, the radio wave emitted from the portable terminal is operated as an energy source, and there is no need to incorporate a battery. .

In the invention according to claim 11 , the RFID tag is fixed to the outer surface portion of the air motor portion, and the RFID tag can be accommodated and separated outward from the outer surface of the air motor portion at a predetermined interval. A base portion and a cover portion that can cover the RFID tag and the base plate portion are provided.

In invention of Claims 1-10, it is comprised by the RFID tag with which each equipment was mounted | worn and stored the information regarding each equipment, and the portable terminal device which can read / write the information of the said RFID tag, Information related to each facility is managed only by the RFID tag, and a management system can be formed only by the RFID tag and the portable terminal mounted on each facility and apparatus. Since no wired LAN or wireless LAN equipment for accessing the database server from the portable terminal is required, the equipment cost required for configuring the management system can be greatly reduced. it can.

  In addition, transmission of business instructions at the work site is very important for business management. However, since the RFID tag can store items to be transmitted to the next maintenance worker for each valve, Compared with the case where items to be communicated with memos, etc., work transmission errors can be eliminated, so that a reliable business instruction system can be established on site.

  In addition, since the necessary items to be sent can be directly written to the RFID tag of the model or equipment that requires maintenance, it is possible to eliminate misunderstandings due to the model and equipment and to transfer important communication information to the RFID tag of the relevant model or equipment. Since the information is directly written, it is possible to reliably convey work information and the like as compared to the case of separately transmitting and transmitting messages using a medium.

  In recent years, in the food industry, etc., it has become possible to grasp the food movement history during production, processing, and distribution processes from the viewpoint of preventing food accidents and providing safety and security to consumers and consumers. The concept of “traceability” is introduced. In this case, for example, as a traceability in the food industry, a so-called “raw material-derived traceability system” that manages based on the origin of the raw material food used in the liquid product is generally used. In the process, there is also a “manufacturing process traceability system” that specifies that a predetermined tank is manufactured from a predetermined tank via a predetermined production line.

  That is, information indicating that “the valve through which the predetermined beverage product has passed is maintained at a predetermined date and time”, information indicating that “the valve through which the predetermined beverage product has been used is being used for a predetermined period”, etc. In addition to the above-mentioned “traceability derived from raw materials” and “traceability of manufacturing process”, is important as a traceability management element. In this case, until now, for example, the management method of “traceability based on maintenance work” of food manufacturing equipment in food manufacturing plants is not yet common, and in a small number of management systems, A large management system was needed.

However, in the invention described in claim 1 , since maintenance information can be written to the RFID tag attached to the individual equipment and the information written by the portable information terminal can be read, when an accident or the like occurs, Even when there is no large-scale LAN equipment or management server when a production line is specified, the maintenance history can be grasped directly and quickly on site, and the management method of “traceability based on maintenance work” is simple and quick. Can be executed.

  In addition, as described above, since it is possible to simultaneously grasp the presence or absence of special notification items related to maintenance and use, it is possible to grasp whether or not there was a cause in the maintenance and use of plant component equipment, without increasing costs. , “Manufacturing Process Traceability” can be implemented.

  Furthermore, since a conventional information management device such as a database server that centrally manages information is not required, an operator needs to access the information management device that is the core of the management system at the time of maintenance. Therefore, it is possible to provide an equipment management system in a production plant that can quickly and easily acquire maintenance information.

In addition, in the facility management system in the manufacturing plant according to the first aspect of the invention, in addition to the above-described effect, the portable terminal uses a unique flag register transmitted by the RFID tag when accessing the RFID tag. Since it is configured to be able to read / write (read / write) information by acquiring the RFID tag specific flag register, the RFID tag information can be read by the portable information terminal, I can't write information. As a result, when a certain worker starts the maintenance work, only the worker reads the maintenance information of the RFID tag and performs the maintenance work. A system for writing information indicating that the maintenance work has been completed is established, and the certainty of the maintenance work can be improved. As a result, the management accuracy as an equipment management system in the manufacturing plant can be improved.
Therefore, it is possible to prevent a plurality of workers from overwriting the same RFID tag at the manufacturing site of liquid products (especially food, milk, dairy products). When a worker starts maintenance work and temporarily leaves the site due to the circumstances of the worker, other portable terminals that have repeatedly accessed the same RFID tag without completing the maintenance work of the valve device It is possible to prevent a situation in which the valve device is used in another pipe line or the like without knowing the circumstances by another maintenance worker who owns the machine.
As a result, at the manufacturing site of liquid products (especially food, milk, dairy products), a certain worker starts maintenance work for a certain valve device, and temporarily leaves the site due to the circumstances of the worker, To avoid a very inappropriate situation from a hygienic point of view, when another worker who does not know the situation moves the valve device that has not yet undergone maintenance work to another department and continues to use it. can do.

  In the inventions according to claims 4 and 5, in a production plant for fluid products for producing various liquid foods, a great number of valve devices are installed in the pipeline, In view of the fact that the valve device is also specified, the valve device used in a pipeline through which a certain liquid product circulates cannot be easily replaced with a pipeline through which another liquid product circulates. In a fluid product manufacturing plant, it is possible to easily and accurately determine whether or not to replace a valve device during maintenance.

  In addition to the above effects, the information stored in the RFID tag includes a use management manual (work procedure manual, instruction manual, etc.) in addition to the above effects. In addition, all information related to the valve device is integrated with the valve device, and the operator can easily obtain all relevant information related to the valve device in managing the equipment and the device. It can be obtained on site, and maintenance work can be performed quickly and accurately.

  In the invention according to claim 7, in addition to the above effect, the information related to the valve device stored in the RFID tag includes character information indicating the use environment of the valve. The environment in which the valve device was used can be specifically recognized at the work site, the life of the valve device can be determined, and the possibility of subsequent use can be examined and determined, improving the quality of maintenance work. Can be achieved.

  In the invention according to claim 8, in addition to the above effect, the information related to the valve device stored in the RFID tag includes image information indicating the use environment of the valve. Recognize the environment in which the valve device was used at a glance and be able to judge the life of the valve device and examine and determine the possibility of subsequent use, improving the quality of maintenance work Can be achieved.

In the invention described in claim 10 , since the RFID tag is constituted by a passive tag and operates using radio waves emitted from a portable terminal as an energy source, there is no need to incorporate or arrange a battery in the RFID tag. . As a result, the configuration of the RFID tag is simple and small, so it can be easily mounted on various plant equipment such as valve devices, and in the work environment (site) of the plant equipment for many years. An equipment management system in a production plant that can withstand use can be provided.

In the invention described in claim 11 , since the RFID tag has a base portion that is fixed to the outer surface portion of the air motor portion and can be separated from the outer surface portion of the air motor portion by a predetermined distance, Regardless of the existence, communication with the portable terminal can be performed without any inadequacy. In addition, since the cover member is provided, the RFID tag can be effectively protected, and can be protected against an external impact, and the durability of the RFID tag can be ensured.

  Hereinafter, based on an embodiment, the case where the equipment management system in the manufacturing plant concerning the present invention is applied to the manufacturing plant of a liquid product is illustrated and explained in detail.

  As shown in FIG. 1, the facility management system 10 in the manufacturing plant according to the present embodiment is mounted on a manufacturing facility for various fluid products, stores an RFID tag 11 that stores information on each facility, and the RFID tag 11. The mobile terminal 12 is configured to read / write information, and the information on each facility is managed only by the RFID tag 11.

  In the present embodiment, the RFID tag 11 is disposed in a fluid product manufacturing pipeline (not shown) of a liquid product manufacturing plant, and is attached to a valve device 13 that can control the opening and closing of the pipeline. Yes. That is, as shown in FIG. 1, the RFID tag 11 is mounted on an air motor unit 14 that can open and close a valve body in the valve device 13, and manufactures all fluid products arranged in the plant. The RFID tags 11 are attached to all the valve devices 13 disposed in the pipeline.

  As shown in FIG. 1, in the present embodiment, the RFID tag 11 is fixed to the upper end portion of the outer surface portion 15 of the air motor portion 14. As shown in FIG. 2, the RFID tag 11 is formed in a substantially square shape on a plane, has a thickness dimension of about 1 mm, and a width dimension of about 5 mm. The RFID tag 11 is fixed to the air motor unit 14 by a base member 16 and a cover member 18.

  As shown in FIG. 3, in the present embodiment, the RFID tag 11 is accommodated in the outer surface portion 15 of the air motor 14 and is spaced outward from the outer surface portion 15 of the air motor portion 14 by a predetermined distance. The base portion 16 that can be separated by the adhesive is affixed and fixed by an adhesive 29 having excellent water resistance and durability. The base portion 16 is formed in a substantially planar disk shape, and a planar substantially square-shaped recess portion 17 that accommodates the RFID tag 11 is opened at the center portion.

  The base portion 16 is formed of a material having impact resistance and durability, such as synthetic resin, and the depth dimension and width dimension of the concave portion 17 are substantially the same as the thickness dimension and width dimension of the RFID tag 11. When the RFID tag 11 is press-fitted at the time of mounting, the RFID tag 11 can be mounted in the recess 17 with both the upper surface portions 30 being flush with each other. Moreover, the thickness dimension of the said recessed part 17 of the said base part 16 is formed in 1 mm.

  As shown in FIGS. 2 and 3, the cover member 18 has a disk shape so that the base member 16 can be accommodated, and is formed in a substantially U-shaped cross section. It is formed of a material having impact resistance and durability, and is configured so that the base portion 16 can be completely covered from above in a state where the RFID tag 11 is housed in the recess 17. That is, the depth dimension of the storage part 19 of the cover member 18 is formed slightly larger than the thickness dimension of the base part 16, and the diameter dimension of the storage part 19 is the same as the width dimension of the base part 16. In addition, a flange portion 21 is provided at the periphery of the lower end portion of the side surface portion 20, and is fixed to the outer surface portion 15 of the air motor portion 14 using the adhesive 29 by the flange portion 21. It is.

  Further, in the present embodiment, the RFID tag 11 is operated by a so-called “passive tag” that operates using radio waves emitted from a portable terminal as an energy source and does not need to incorporate a battery on the RFID tag 11 side. It is configured. Therefore, in the present embodiment, when the RFID tag 11 is attached to the air motor portion 14 of the valve device 13, the RFID tag 11 is press-fitted and fixed in the concave portion 17 of the base portion 16. Thereafter, the cover member 18 is covered from the surface side of the base portion 16, and an adhesive is applied to the flange portion 21 with the RFID tag 11 covered from the surface side of the base portion 16. The outer surface portion 15 is fixed in the vicinity of the upper end portion.

  In the present embodiment, the white seal 22 is then used to inform the worker that the RFID tag 11 is fixed to the valve device 13 in the liquid product pipeline in the plant. The cover member 18 is pasted so as to cover it. As shown in FIGS. 3 and 4, the seal 22 is formed in a substantially rectangular shape on a plane, and a hole portion 23 through which the cover member 18 passes is formed in the center portion. A QR code (registered trademark) 24 is printed at one corner.

  In the present embodiment, the information written in the RFID tag 11 is as follows.

  1. History information of the result of maintenance work on each facility by text information and image information: This history information includes "information on specific work name of maintenance", "year, month, day, time information on which maintenance work was performed" ”,“ Department of the worker who performed the maintenance work, character information indicating name information ”, and the like.

  2. Valve device usage management manual information based on text information and image information: This usage management manual information includes "the usage information of the valve device", "specification information of the valve device", and "maintenance manual information of the valve device". The character information shown is included.

  3. Image information indicating the environment in the plant in which the valve device was used: This image information includes the pipeline in which the valve device has been used in the past, the plant in which the valve device and the valve device were installed, A still image or a moving image of image information indicating the environment is included.

  Further, in the present embodiment, “writing work” and “reading work” of the above-described various information on the RFID tag 11 are performed by a personal digital assistant (PDA).

  In the present embodiment, the PDA is various general-purpose PDAs, and all can be applied as long as the PDA is configured to be able to read and write information to and from the RFID tag. As shown in FIG. 1, in the present embodiment, the PDA 25 includes a PDA main body 26 and a pen-type scanner 27 connected to the PDA main body 26. The pen-type scanner 27 is configured to emit radio waves by the power of the power source provided on the PDA main body 26 side to access the RFID tag 11 configured by the passive tag according to the present embodiment.

  Therefore, in this embodiment, the field worker always carries the PDA 25 at the plant work site, and fixes the pen-type scanner 27 to the valve device 13 to be worked as necessary during maintenance. By performing various maintenance information on the valve device 13 by reading the various maintenance information written on the RFID tag 11 in the vicinity of the RFID tag 11 and writing the result of the maintenance work performed, Further, maintenance work information can be stored in the RFID tag 11.

  In this embodiment, when the RFID tag 11 is accessed, the RFID tag 11 transmits a unique flag register to the PDA 25, and only the PDA that has acquired the flag register receives the RFID tag. The information of the tag 11 can be read or written. That is, in the present embodiment, when the PDA acquires the flag register “1”, the maintenance information of the RFID tag 11 can be “read (read)”, and the flag “0” When the PDA acquires the register, the maintenance information can be “written (written)” to the RFID tag 11. This point is based on the following circumstances.

  At a plant work site, a plurality of maintenance workers are working, but with respect to a predetermined valve device 13, when a certain worker starts the maintenance work, the same worker completes the maintenance work. This is necessary from the viewpoint of safety of maintenance work.

  For example, regarding a certain valve device 13, a certain worker may start a maintenance work and temporarily leave the place due to the circumstances of the worker. In such a case, another worker determines that the maintenance work of the valve device 13 has been completed, and actually moves the valve device 13 that has not undergone the maintenance work to another department for use. There is also the possibility of doing. In such a case, the valve device 13 in which the maintenance work has not been completed is continued to be used as it is, and is considered from a hygienic viewpoint in the production site of liquid products (especially food, milk, and dairy products). If this is the case, it will be extremely inappropriate.

  In order to avoid such a situation, as in the present embodiment, when a specific flag register is specified for the RFID tag 11 and the RFID tag 11 is accessed by a PDA, the specific flag As long as the register is not acquired, it is effective to configure the PDA so that information cannot be read or written.

  As a result, it is possible to prevent a plurality of workers from accessing the same RFID tag redundantly, to prevent redundant writing work to the same RFID tag, and to perform maintenance work of the valve device 13. It is possible to prevent a situation in which the valve device 13 is used in another pipe line or the like by a maintenance worker who owns another PDA that has repeatedly accessed the same RFID tag without being completed.

  In the present embodiment, the facility management system 10 is configured only by the RFID tag 11 and the PDA 25 fixed to the valve device 13, but in order to centrally manage maintenance information and improve management efficiency, As shown in FIG. 5, if necessary, a maintenance information management PC 28 is installed in the plant management department, the maintenance work information stored in the PDA 25 is uploaded, and the maintenance work instructions are downloaded to the PDA 25. You may comprise so that it can do.

  Even in such a configuration, when a conventional information management device such as a database for centrally managing management information and a wireless LAN facility for accessing the database server from a mobile terminal are installed. Compared to the above, the cost required to configure the management system can be reduced. In the present embodiment, as described above, the RFID tag 11 is composed of a passive tag, and based on the “radio wave system” instead of the “electromagnetic induction system”, the radio wave emitted from the mobile terminal is transmitted to the antenna of the RFID tag. Therefore, it is configured to receive information and transmit information, and operates using radio waves emitted from a portable terminal as an energy source, so there is no need to incorporate a battery.

  As a result, the structure of the RFID tag is simple and small, so that it can be easily attached to various plant equipment such as a valve device, and can withstand long-term use in the work environment of the plant equipment. An equipment management system in a product manufacturing plant can be provided.

  Further, the RFID tag 11 is a passive tag, and an operator can acquire information stored in the RFID tag from a farther position than the “electromagnetic induction method”, so that a fluid product manufacturing plant can be obtained. In the case where the valve device 13 requiring maintenance is disposed in the pipe line, the RFID tag 11 of the valve device 13 can be accessed from a relatively remote location, and maintenance information can be obtained. After the maintenance work is completed, it is possible to access the RFID tag 11 from a relatively remote location and write the completed maintenance information, so that the maintenance information is read from the RFID tag 11 and the maintenance to the RFID tag 11 is performed. Information can be written easily.

  The equipment management system in the production plant according to the present invention can be widely applied to various product production plants.
