<Maintenance management device 1>
The vendor information acquisition unit 11 acquires the vendor information possessed by the vendor of the field device from the vendor information providing device 2 by using the identification information for identifying the field device. Field equipment is a sensor, actuator, or the like installed in a plant and having a communication function for communicating via a wired or wireless network. The sensor measures physical quantity data such as pressure, temperature, pH, product flow rate, etc. in the process of the plant, for example. The actuator is a valve, a pump, or the like. Some parts such as sensor elements used in field equipment deteriorate over time (deterioration over time). For field equipment that has parts that deteriorate over time, maintenance work for replacement is performed when an alarm prompting the replacement of parts is output from the field equipment or at a predetermined replacement cycle. In the maintenance work of replacement, in the case of a field device in which only parts can be replaced, parts are replaced, and in the case of a field device in which parts cannot be replaced, the entire field device (main body) is replaced. In the following explanation, the replacement of field equipment may include the replacement of parts. The vendor information acquisition unit 11 acquires the alarm information and the information necessary for exchanging the field equipment prompted in response to the alarm information from the vendor information held by the vendor of the field equipment. The details of the vendor information acquired by the vendor information acquisition unit 11 will be described later.

The vendor information acquisition unit 11 acquires vendor information using identification information that identifies a field device. The identification information for identifying the field device is, for example, a serial number attached to each field device to uniquely identify the field device. (Identifier). The identification information that identifies the field device may be information such as the model of the field device. In the following description, an identifier will be exemplified as identification information for identifying the field device.
The identification information may include, for example, redundant information indicating that the identification information is legitimate information. The vendor information acquisition unit 11 transmits the identification information to the vendor information providing device 2 as XML (XML (Extension Markup Language) data, for example, and acquires the vendor information corresponding to the transmitted identification information from the vendor information providing device 2. The vendor information acquisition unit 11 acquires vendor information, for example, when a user gives an instruction to acquire the vendor information. The vendor information acquisition unit 11 may acquire vendor information on a regular basis.

The user information acquisition unit 12 acquires the user information possessed by the user who uses the field device from the user information providing device 3. A user who uses a field device is a user who can provide information on the field device used (owned), and for example, even a user who operates a plant or the like in which the field device is installed in the field. It may be a user who maintains the equipment. The user information includes, for example, a device ledger of field devices managed by the user and inventory information of field devices. The user information may include information on the usage status such as the operating time of the field device and the replacement history. The user information acquisition unit 12 acquires user information when an instruction for acquisition is given by the user. The user information acquisition unit 12 may acquire user information on a regular basis. The details of the user information including the usage status acquired by the vendor information acquisition unit 11 will be described later.

The join information storage unit 13 stores the join information obtained by table-joining the vendor information acquired from the vendor information providing device 2 and the usage status acquired from the user information providing device 3. Table join is a process of joining (merging) a plurality of information represented by table (tabular) data, and is a process of joining information existing in a plurality of tables searched by a predetermined search key into one. Is. The search key is a data item common to a plurality of tables, and in the present embodiment, a case where the above-mentioned identifier and alarm information are used as the search key will be illustrated. That is, the combined information storage unit 13 stores the combined information in which the vendor information and the user information are combined in a table using the identifier and the alarm information as search keys. The table join process is executed by the join information storage unit 13. The join information storage unit 13 stores a new table (join table) generated by collecting the joined vendor information. An example of the newly generated join table will be described later with reference to FIG.

The search key can be determined by the table to be joined, and for example, the model of the field device may be used as the search key. The model of the field device is information for specifying the specifications of the field device, and the field device of the same model has the same alarm information and the information necessary for exchanging the field device prompted in response to the alarm information. To do. Further, the combined information storage unit 13 may store, for example, the combined information in which the vendor information is combined or the combined information in which the user information is combined. Further, the table join process may be executed by the vendor information acquisition unit 11 or the user information acquisition unit 12. Further, the combined information storage unit 13 may store only the combined information (link information) of the vendor information. That is, the table join may be one that logically joins (associates) a plurality of table data.

The alarm information acquisition unit 14 acquires alarm information output from the field device.
The alarm information is information indicating the content of the alarm, and is, for example, an alarm number determined for each field device. The maintenance worker carries out the necessary maintenance work based on the alarm information. For example, when the alarm information is content (alarm number, etc.) that prompts the replacement of a specific part used in the field device, the maintenance worker uses the alarm number output from the field device, etc. The meaning of the alarm number can be confirmed manually, and the parts specified by the alarm number can be replaced. The alarm information acquisition unit 14 automatically collects alarm information acquired by the maintenance worker with the maintenance equipment. The alarm information acquisition unit 14 acquires alarm information from, for example, a field device, an operation control device such as a PLC (Programmable Logic Controller), a maintenance device, or the like. In the present embodiment, the case where the alarm information acquired by the alarm information acquisition unit 14 is information determined for each model of the field device has been described, but the model of the field device is a communication that the field device can communicate with. The method may be included. For example, depending on the communication method, troubles related to communication reserved in advance may be assigned to the alarm number output by the field device. Therefore, the alarm information may include an alarm number common to various types of field devices.

The work order processing unit 15 generates a work order or provides a work order. A work order is information or the content of the information instructing the implementation of maintenance work of field equipment. A work order is, for example, a command instructing calibration or replacement of a field device. Further, the work order may be character information or image information (work instruction sheet) indicating the procedure of the work content to be performed.

<Generation of work order>
The work order processing unit 15 generates a work order for maintenance work of field equipment based on the acquired vendor information and user information. For example, the work order processing unit 15 includes the model of the field device that outputs the alarm acquired as user information, the output alarm number, and the model information of the field device acquired as vendor information. A work order is generated based on the alarm number in the field device of the model and the coping method corresponding to the alarm number. The model information of the field device, the alarm number in the field device of the model, and the coping method corresponding to the alarm number are stored in the combined information storage unit 13. That is, the work order processing unit 15 searches the combined information storage unit 13 from the acquired field device model and alarm number, and specifies a coping method. In the present embodiment, the work order processing unit 15 generates a predetermined work order triggered by the acquisition of the alarm information, but the timing and contents of the work order generation are arbitrary. For example, after acquiring the alarm information, the maintenance worker who provides the work order may be specified, and then the work order may be generated according to the skill of the specified maintenance worker. A work order is, for example, textual information in which the procedure of maintenance work is itemized. The work order may be a still image file or a moving image file that explains the work procedure with a still image or a moving image.

<Providing work orders>
The work order processing unit 15 provides the generated work order to the maintenance worker. The work order processing unit 15 may, for example, send a work order to a maintenance device carried by a maintenance worker by e-mail or the like, or make it available for download. Further, the work order processing unit 15 may provide a work order to the maintenance manager who manages the maintenance work. Further, the work order processing unit 15 may provide the work order to the maintenance management system that records the maintenance history of the field equipment or manages the maintenance plan of the field equipment.

The parts order processing unit 16 generates a parts order or provides a parts order. The parts order is information or order contents for ordering parts (replacement parts) used in field equipment.

<Generation of parts order>
The parts order processing unit 16 generates a parts order for ordering parts used in the field device based on the vendor information acquired from the vendor information providing device 2 and the user information acquired from the user information providing device. To do. The vendor information acquired from the vendor information providing device 2 includes, for example, alarm information determined for each model of the field device and parts information to be replaced in response to the alarm information. That is, the parts order processing unit 16 can generate information for ordering parts for which replacement is urged. The parts order processing unit 16 can refer to the information on the number of parts in stock acquired as user information. The parts order processing unit 16 determines, for example, whether or not the parts to be replaced are in stock, or whether or not the number of parts to be replaced is less than the predetermined number of stocks, and when the parts are out of stock or the number of parts in stock is less than or equal to the predetermined value. If it becomes, a parts order is generated.

<Providing parts orders>
The parts order processing unit 16 provides the generated parts order to the ordering system that manages the ordering business. The ordering system is, for example, a function operated in a core system that manages the management resources of the entire company. By providing the generated parts order to the ordering system, the parts order processing unit 16 can automatically manage the inventory quantity of an appropriate quantity of parts. Therefore, the maintenance worker or the maintenance manager does not need to check the inventory of the parts and place an order for the parts every time the replacement work occurs, and the maintenance management work can be made more efficient. .. The method of providing the generated parts order is arbitrary. For example, the parts order processing unit 16 may print out a purchase order from a printer based on the generated parts order. Further, the parts order processing unit 16 may display the generated parts order as character information on a display unit (not shown).

<Vendor information providing device 2>
The vendor information providing device 2 provides vendor information to the maintenance management device 1. The vendor information is information that can be acquired from a vendor that provides the field device, and is, for example, alarm information output by the field device, identification information of the field device, or the like.

The alarm information storage unit 21 deals with the alarm information, which stores the alarm information determined for each model of the field device, the coping method for dealing with the alarm information, and the parts information for dealing with the alarm information and to be replaced. The coping method is, for example, information on the procedure of maintenance work that is prompted to be carried out in response to the occurrence of an alarm. Maintenance work that is encouraged to be carried out includes, for example, field equipment inspection work, field equipment parameter confirmation work, parts replacement necessity determination method, and parts replacement method. The coping method differs depending on the model of the field device and the alarm information, but the alarm information storage unit 21 may store the coping method common to the plurality of models and the alarm information.

The identification information storage unit 22 stores the identification information of the field device and provides the identification information of the field device to the user. The identification information of the field device includes, for example, a serial number that can uniquely identify the field device. Etc., and information on the model (model name) of the field device of the identifier. The identification information of the field device may include information such as a manufacturing date in which the field device having the identifier is manufactured and a shipping date (purchase date of the user) in which the field device having the identifier is shipped. As described above, since the vendor information of the field device differs depending on the model of the shield device, the user acquires the vendor information from the model of the field device.

The identification information storage unit 24 can identify a unique field device by using, for example, an identifier that uniquely identifies the field device as a search key, and provide information such as a model of the specified field device as vendor information. It is possible to prevent unauthorized information acquisition by including a check key (redundant information) that cannot be known if the field device is not at hand in the search key.

<User information providing device 3>
The user information providing device 3 provides user information to the maintenance management device 1. The user information is information that can be acquired from a user who uses the field device, and is, for example, a device ledger of the field device, an inventory ledger of the field device, and the like. The user information may include usage status such as parts replacement history of field equipment, operation history of field equipment, and calibration history of field equipment.

The device ledger storage unit 31 stores the device ledger of the field device. The equipment ledger of the field equipment is information that records the field equipment managed by the user. For example, an identifier that uniquely identifies the field equipment, a tag name given to the field equipment installed in the plant, and the field equipment in the plant. Includes information such as the installation date indicating the installation date and the installation location indicating the installation location of the field equipment in the plant. For example, when a maintenance worker installs a field device in a plant, the information on the field device is added to the device ledger, and when the field device is removed from the plant, the information on the field device is deleted.

The inventory information storage unit 32 stores inventory (spare parts) information of field equipment. The inventory information of the field equipment is the inventory information of the field equipment itself or the inventory information of the parts used in the field equipment. In the plant, stock an appropriate number of spare parts in case of regular maintenance work or sudden failure. Inventory information of field equipment is, for example, information on warehousing and delivery in a warehouse. The inventory information of the field equipment includes, for example, information such as the model (or part number) of the field equipment, the number of stocks, and the storage location. The inventory information may include information on the field equipment currently being ordered.

The functions of the vendor information acquisition unit 11, the user information acquisition unit 12, the coupling information storage unit 13, the alarm information acquisition unit 14, the work order processing unit 15, and the parts order processing unit 16 of the maintenance management device 1 in FIG. 1 are , The case realized by software was explained. However, one or more of the above functions may be realized by hardware. Further, each of the above functions may be performed by dividing one function into a plurality of functions. Further, each of the above functions may be implemented by aggregating two or more functions into one function. Further, the functions of the alarm information storage unit 21 and the identification information storage unit 22 of the vendor information providing device 2 or the functions of the device ledger storage unit 31 and the inventory information storage unit 32 of the user information providing device 3 are also described above. One or more functions in each function may be realized by hardware. Although FIG. 1 shows a maintenance management system 100 having three devices, a maintenance management device 1, a vendor information providing device 2, and a user information providing device 3, the maintenance management device 1, the vendor information providing device 2, or the user information providing device 3 is shown. One or more functions of each device of the device 3 may be realized in another device. That is, the maintenance management system 100 shown in FIG. 1 is one aspect of the maintenance management device in the present embodiment, and the configuration of the maintenance management device 1 is limited by the configuration of the vendor information providing device 2 or the user information providing device 3. is not.

Next, the vendor information acquired by the vendor information acquisition unit 11 from the vendor information providing device 2 will be described with reference to FIGS. 2 to 3. The vendor information can be acquired by the vendor information acquisition unit 11 using the identification information that identifies the field device. The vendor information described with reference to FIGS. 2 to 3 is the same information as that described in the instruction manual that is included in the field device or that can be downloaded from the vendor's website, for example. By acquiring these vendor information, the vendor information acquisition unit 11 can save the user the trouble of checking the vendor information for each field device or each part from the instruction manual or the like.

FIG. 2 is a diagram showing an example of “alarm information” of vendor information acquired by the maintenance management device 1 of the embodiment. The alarm information is stored in the alarm information storage unit 21 of the vendor information providing device 2.

In FIG. 2, the alarm information has data items of "Model Name", "Alarm NO.", "Procedure" and "Part". The data item of "Model Name" indicates the model of the field device. The model of the field device may be the communication standard of the field device as described above. The data item of "Alarm NO." Is the alarm information output from the field device, and exemplifies the alarm number. The number of alarms to which an alarm number is assigned depends on the model of the field device. The data item of "Procedure" indicates a coping method specified by the combination of the model information of "Model Name" and the alarm information of "Alarm NO.". The coping method is, for example, information indicating a procedure of maintenance work. The "part" data item indicates information about the part used to perform the procedure in the "procedure" data item.

For example, in a field device in which "Model Name" is "AAA-P10", "Alarm NO." Outputs two types of alarms, "AL10" and "AL20". When the alarm of "AL10" is output, the "procedure" prompts the implementation of the maintenance work of "measure 1". In the maintenance work of "Countermeasure 1", replacement parts whose "parts" are "P12345" are used.

In addition, the field device whose "Model Name" is "BBB-F11" outputs four types of alarms whose "Alarm NO." Is "AL10" to "AL40". When the alarm of "AL10" is output, the "procedure" prompts the implementation of the maintenance work of "measure 3". In the maintenance work of "Countermeasure 3", "parts" is "none", that is, it indicates that replacement parts are unnecessary.

Here, "AL10" of "Alarm NO." Has the same alarm number in the field devices of "AAA-P10" and "BBB-F11". The alarm number may be represented by, for example, a 4-bit data string, and the same alarm number may be common to different types of field devices. In FIG. 2, as described above, the coping method shown in the “procedure” is specified in the combination of the model and the alarm number.

Further, in FIG. 2, the case where one part is used in one alarm number (one countermeasure) is shown, but a plurality of parts may be used in one countermeasure. In that case, the ordering of parts according to the inventory of parts shall be determined and executed for each part.

FIG. 3 is a diagram showing an example of “identification information” of vendor information acquired by the maintenance management device 1 of the embodiment. The identification information is stored in the identification information storage unit 22 of the vendor information providing device 2.

The data item of the "identifier" is information for uniquely identifying (identifying) the field device, for example, the serial number. Is. That is, in the identification information, the vendor stores the identifier of the field device and the model of the field device in association with each other. When the vendor information acquisition unit 11 searches for the identifier of the field device as a search key in the identification information, the information of "Model Name" of the field device can be acquired. Further, if the information of "Model Name" is known, it is possible to acquire the alarm information described with reference to FIG. 2 as vendor information using "Model Name" as a search key. In order to deal with the alarm information output from the field device, it is necessary to refer to a different coping method for each field device. In the present embodiment, the maintenance management device 1 can easily acquire the information of the "procedure" and the "part" by searching the vendor information using the identifier of the field device as the search key. Therefore, the user of the field device does not need to check the information on how to deal with the alarm for each field device, and the efficiency of maintenance management can be improved.

In addition, in FIG. 2, the case where the data items of "identifier" and "Model Name" are included as the identification information has been described, but the identification information includes, for example, data items such as "manufacturing date" and "shipment date". You may have. The "manufacturing date" and the like can be referred to in the maintenance management of parts that deteriorate over time.
