Description

BACKGROUND OF THE INVENTIONField of the InventionThe present invention relates to a management system that manages machining apparatuses using a coolant.Related ArtConventionally, a machining apparatus that chip-processes a workpiece using a cutting fluid or a lubricating oil is known. This machining apparatus includes motors, driving apparatuses, control apparatuses, etc. In the case of printed substrates, as for resin components used for airtight holding members and the like, which are installed in the motor, the driving apparatus, the control apparatus, etc., which are used in environments where the cutting fluid, the lubricating oil, etc., used in the machining meet, there is a possibility of occurrence of chemical changes (aging) and occurrence of malfunction (e.g., deterioration or defect of the airtight mechanism or components) of the motor, etc. Thereby, the machining apparatus may be stopped and may not be capable of completing the machining of the workpiece for a long period of time.In the case of failure of a machining apparatus, the possibility of failure of machining apparatuses of the same type for which the same type of cutting fluid or lubricating oil is used is considered, and countermeasures such as performing general maintenance of the machining apparatuses of the same type or individual maintenance of the stopped machining apparatus are taken. In general maintenance, machining apparatuses on which no wear has occurred can be unnecessarily maintained. Moreover, in individual maintenance of stopped machines, countermeasures may be taken too late in machining apparatuses of the same type in which wear progresses.Therefore, a system has been proposed in which disturbance information is shared among the machining apparatuses for which cutting fluid is used and applied to other machining apparatuses (for example, see Patent Document 1). In addition, a system has been proposed that collects data on failures of processing devices in a server, analyzes the data, and notifies occurrence of an abnormality (for example, see Patent Document 2). Moreover, a system that detects an abnormality from a decrease in the concentration of the cutting liquid has been proposed (see, e.g., Patent Document 3).Patent Document 1: Japanese Unexamined Patent Application, Publication No. JP 2009-282 822 APatent Document 2: Japanese Unexamined Patent Application, Publication No. JP 2009-175 793 APatent Document 3: Japanese Unexamined Patent Application, Publication No. JP H09-85 585 ASUMMARY OF THE INVENTIONThe systems disclosed in Patent Documents 1 to 3 are useful in that they are suitable for handling troubles of individual machining apparatuses. On the other hand, these systems are not suitable for somewhat predicting the frequency of occurrence of troubles in consideration of the operating conditions of the individual machining apparatuses.It is an object of the present invention to provide a management system capable of predicting the occurrence frequency of failures in consideration of the operating conditions of individual machining apparatuses.A first aspect of the present invention relates to a management system (e.g., the later-described management system 1) that manages machining devices (e.g., the later-described machining device 100) using a coolant, the management system including: a duration information generation unit (e.g., the later-described duration information generation unit 102) that generates duration information including a setup duration and an operation duration of the machining device; a condition information generation unit (e.g., the later-described condition information generation unit 103) that generates condition information based on setup conditions and operation conditions of the machining device; a retrieval unit (e.g., the retrieval unit 11 described later) that retrieves the duration information and the condition information to each of the machining devices; an analysis unit (e.g., the analysis unit 23 described later) that analyzes a frequency of occurrence of failures of the machining device based on the duration information and the condition information and failure occurrence information caused by the coolant; and a notification unit (e.g., the notification unit 104 described later) that outputs notification information based on the frequency of occurrence of failures.According to a second aspect of the present invention, in the management system described in the first aspect, the analysis unit may include: a calculation element (e.g., the calculation element 231 described later) that calculates a malfunction occurrence frequency of each of the machining devices by comparing the malfunction occurrence information with the duration information; and a correction element (e.g., the correction element 232 described later) that corrects a malfunction occurrence frequency calculated by the calculation element to a malfunction occurrence frequency of each of the machining devices based on the condition information.According to a third aspect of the present invention, in the management system described in the second aspect, the correction unit may correct a frequency of occurrence of failures using the temperature and humidity of an atmosphere surrounding the processing device based on a placement location of the processing device.According to a fourth aspect of the present invention, in the management system described in any one of the first to third aspects, in the event of occurrence of failure of one of the machining devices of the same type, the retrieval unit may retrieve the information on duration and the information on conditions from another one of the machining devices among the machining devices of the same type.According to a fifth aspect of the present invention, in the management system described in any one of the first to fourth aspects, the machining device may include a motor, and the information on the conditions may include a rotation state of the motor.According to a sixth aspect of the present invention, the management system described in any one of the first to fifth aspects may further include an associating unit (e.g., the associating unit 15 described later) that associates a total load amount of a plurality of the machining devices with each of the machining devices based on the occurrence frequency of failures.According to the present invention, it is possible to provide a management system capable of predicting the frequency of occurrence of failures in consideration of the operating conditions of individual machining apparatuses.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a schematic block diagram showing a management system according to a first embodiment of the present invention;

First, a processing device 100 managed by the management system 1 according to the first embodiment will be explained.The machining device 100 is, for example, a machine tool such as a lathe or a machining center, and includes motors, devices for driving and controlling them, etc. The machining device 100 machines a workpiece using a coolant such as a cutting fluid, a lubricating oil, and a liquid coolant.A plurality of the machining apparatuses 100 are installed in a manufacturing facility in which workpieces are machined, for example. Each of the processing devices 100 is installed at a different location within the manufacturing facility and operates in a different environment (e.g., atmosphere). Each of the processing devices 100 thereby operates in a different ambient temperature and humidity, for example. In addition, the machining apparatus 100 becomes suitable for machining a workpiece under a load (e.g., a work load) depending on a set load magnitude.In the processing of a workpiece, the coolant may adhere to a printed substrate, resin components, etc. incorporated in the motor, the driving device, or the control device of the processing device 100. In the processing apparatus 100, failure of insulation of the motor and corrosion on the printed substrate may occur due to chemical change by the adhering coolant. In addition, as failure caused by the coolant starts to occur, components that affect the movement of the motor, such as the bearings of the motor, the influence in torque, a positioning error, etc. Therefore, the frequency of occurrence of failure caused by the coolant of the machining device 100 increases with the length of the operation time of the machining device 100.On the other hand, the amount of chemical change due to the coolant even in the same operation time changes according to the operation conditions of the processing apparatus 100. The amount of chemical change due to the coolant changes depending on, for example, the temperature and humidity of the environment of the processing apparatus 100. Specifically, the amount of chemical change due to the coolant increases at a higher temperature of the environment of the processing apparatus 100, and increases as the humidity increases. Therefore, the frequency of occurrence of coolant-caused failures of the machining apparatus 100 differs according to the operating conditions in machining apparatuses 100 of the same type for which the same type of coolant is used even in the same operating time.It should be noted that the same type of refrigerant (e.g., with respect to different type numbers or manufacturers, etc.) The term "coolant" refers to those having the same or similar chemical properties. In addition, machining apparatus 100 of the same type refers to machining apparatuses 100 that can perform the same machining or similar machining on a workpiece.(First Embodiment)Next, referring to FIGS. 1 to 7, a management system 1 according to a first embodiment of the present invention will be explained. The management system 1 according to the present embodiment is a system that manages the machining devices 100 according to individual machining devices 100 of the same type for which the same type of coolant is used. The management system 1 is a system that predicts the occurrence frequency of failures for each machining device 100 in which a coolant is used, and manages the machining devices 100 on the basis of the predicted occurrence frequency of failures. More specifically, the management system 1 is a system that outputs notification information notifying a case where the abnormality occurrence frequency is high in a machining device 100 where a high abnormality occurrence frequency has been determined. The management system 1 includes the processing devices 100, an intermediate server 10, and a higher-order server 20 as shown in FIG. 1.The processing device 100 is in communication with the intermediate server 10 via a network. As shown in FIG. 2, the processing apparatus 100 includes a failure detection unit 101, a duration information generation unit 102, a condition information generation unit 103, and a notification unit 104.The abnormality detection unit 101 detects whether an abnormality occurs in the operation of the machining apparatus 100. Upon detection of the occurrence of a fault, the fault detection unit 101 sends information indicating the event of the occurrence of a fault to the duration information generation unit 102 and the condition information generation unit 103.The duration information generation unit 102 generates duration information from the fault detection unit 101 in the case of receiving information indicating the event of occurrence of a fault. More specifically, the duration information generation unit 102 generates duration information including the operation time elapsed since the installation of a machining apparatus 100. The duration information generation unit 102 transmits the generated duration information to the intermediate server 10.The condition information generation unit 103 generates condition information in the case of receiving information indicating the event of occurrence of a fault from the fault detection unit 101. The condition information generation unit 103 generates condition information based on the operating conditions of the machining apparatus 100. More specifically, the condition information generation unit 103 generates, for example, condition information including the installation location within the manufacturing operation, the rotation speed and the torque of an engine, the conditions under which a malfunction occurs, the type of coolant used, etc. The condition information generation unit 103 transmits the generated condition information to the intermediate server 10.The notification unit 104 is, for example, a display device or an acoustic device, and a device that outputs information by means of display and / or light emission, sound, etc. The notification unit 104 outputs information using display and / or light emission, sound, etc., based on the information transmitted from the intermediate server 10. The notification unit 104 outputs notification information generated by a notification information generation unit 14 described later.The intermediate server 10 is, for example, an edge server for fog computing. The intermediate server 10 is connected to the superordinate server 20 via the Internet N. The intermediate server 10 organizes the information on duration, the information on conditions, and the identification information transmitted from the plurality of processing devices 100. The intermediate server 10 transmits the organized information to the master server 20, and the intermediate server 10 transmits information to each processing device 100 on the basis of the frequency of occurrence of failures transmitted from the master server 20 to the processing device 100. Note that "organize" refers to consolidation of the different information sent from the plurality of processing devices 100 into a set of information. As shown in FIG. 3, the intermediate server 10 includes a retrieval unit 11, a duration information organization unit 12, a condition information organization unit 13, and a notification information generation unit 14.The retrieval unit 11 retrieves, for example, the information on duration including the operation time of the machining apparatus 100 and information on the conditions of each machining apparatus 100 based on the operation conditions of the machining apparatus 100. In addition, the retrieval unit 11 retrieves identification information from each of the plurality of processing devices 100. The retrieval unit 11 sends the retrieved duration information and the identification information to the duration information organization unit 12. In addition, the retrieval unit 11 sends the retrieved condition information and the identification information to the condition information organization unit 13.The duration information organization unit 12 organizes the duration information and the identification information transmitted from each of the plurality of processing apparatuses 100. The duration information organization unit 12 transmits the organized duration information and the identification information to the higher-level server 20.The condition information organization unit 13 organizes the condition information and the identification information of each of the plurality of processing apparatuses 100. The condition information organization unit 13 transmits the organized condition information and the identification information to the higher-level server 20.The notification information generation unit 14 acquires information indicating the frequency of occurrence of failures to each processing device 100 analyzed by the higher-order server 20. The notification information generation unit 14 generates notification information related to the corresponding processing device 100 when the analyzed malfunction occurrence frequency exceeds a predetermined threshold. The notification information generation unit 14 transmits the generated notification information to the notification unit 104 of the corresponding machining apparatus 100.The superordinate server 20 is, for example, a cloud server. The higher-level server 20 analyzes the occurrence frequency of failures for each processing device 100 based on the duration information and the condition information organized and sent by the intermediate server 10. In addition, the master server 20 transmits the analyzed malfunction occurrence frequency to the intermediate server 10.In the malfunction occurrence information database 21, the malfunction occurrence information indicating the frequency of occurrence of malfunction caused by coolant of the machining apparatus 100 is stored. More specifically, the malfunction occurrence information indicating the correlation between the operation time of the machining device 100 and the frequency of occurrence of malfunction caused by aging of components due to the coolant is stored in the malfunction occurrence information database 21. In the disturbance information database 21, the disturbance occurrence information indicating the correlation between the operation time and the frequency of occurrence of disturbance such as that shown in FIG. 5 is stored.In the correction information database 22, the correction amounts for the frequency of occurrence of interference corresponding to the operating conditions of the machining apparatus 100 are stored as correction information. In the correction information database 22, the various information included in the information on the conditions such as the corresponding correction amounts for the frequency of occurrence of disturbances shown in FIG. 6 are stored as the correction information.The analysis unit 23 analyzes the occurrence frequency of failures for each processing device 100 based on the information on the duration and the information on the conditions and the information on the occurrence of failures indicating the occurrence frequency of failures of the processing device 100 caused by coolant. The analysis unit 23 includes a calculation element 231 and a correction element 232.The calculation part 231 calculates the malfunction occurrence frequency for each machining apparatus 100, for example, by comparing the malfunction occurrence information indicating the malfunction occurrence frequency based on the operation time with the duration information. More specifically, the calculation element 231 reads the disturbance occurrence information from the disturbance occurrence information database 21 and compares it with the information transmitted from the intermediate server 10 for duration. The calculation part 231 calculates, as a result of the comparison, the occurrence frequency of failures for each of the plurality of machining devices 100 identified from the identification information. The calculation part 231 sends the calculated malfunction occurrence frequency to the correction part 232. Hereinafter, the occurrence frequency of interference calculated by the calculation element 231 will be described as "occurrence frequency of interference before correction" when discrimination is required.The correction element 232 corrects the occurrence frequency of disturbances before correction calculated by the calculation element 231 on the basis of the information on the conditions, thereby correcting the occurrence frequency of disturbances for each machining apparatus 100. More specifically, the correction element 232 reads the correction information from the correction information database 22. The correction element 232 compares the correction information with the information on the conditions sent from the intermediate server 10. The correction element 232 determines, as a result of the comparison, the correction amount for the frequency of occurrence of defects before the correction for each of the plurality of processing apparatuses 100 identified from the identification information. The correction element 232 corrects the frequency of occurrence of noise before correction using the determined correction amount. The correction element 232 transmits the corrected abnormality occurrence frequency to the notification information generation unit 14 and an association unit. Hereinafter, the occurrence frequency of interference corrected by the correction element 232 will be described as "occurrence frequency of interference after correction" when discrimination is required.Next, with reference to the flowchart of FIG. 7, the processing for managing the processing devices 100 by the management system 1 will be explained. First, in step S 1, the abnormality detection element 101 of each of the plurality of processing apparatuses 100 detects whether or not an abnormality has occurred in any of the processing apparatuses 100. If a failure has occurred (step S 1: YES), the processing proceeds to step S 2. On the other hand, if no fault has occurred (step S 1: NO), the processing repeats step S 1.In step S 2, from the processing device 100 in which a failure has occurred, the duration information, the condition information, and the identification information are transmitted to the intermediate server 10. More specifically, the abnormality detection element 101 transmits information generated by the detection of the abnormality to the duration information generation element 102 and the condition information generation element 103 upon the detection of an abnormality of the machining apparatus 100. The duration information generation element 102 generates and sends information to the intermediate server 10.The condition information generation element 103 generates the condition information and transmits it to the intermediary server 10. the retrieval unit 11 requests transmission of duration information, condition information, and identification information from the processing apparatus 100 in which a failure has occurred. Each of the plurality of processing devices 100 generates the duration information, the condition information, and the identification information in response to the request, and sends them to the intermediate server 10. In addition, the retrieval unit 11 retrieves the information on duration, the information on conditions, and the identification information from the machining apparatuses 100 belonging to the same type and using the same type of coolant as the machining apparatus 100 in which a failure has occurred.In step S 3, the duration information organization unit 12 organizes the duration information and the identification information transmitted from the plurality of processing devices 100, and transmits them to the calculation element 231 of the upper server 20.In step S 4, the calculation part 231 calculates the occurrence frequency of failures before the correction by comparing the operation time included in the duration information with the occurrence information indicating the relationship between the operation time and the occurrence frequency of failures for each machining device 100 identified from the identification information. The calculation part 231 transmits the calculated occurrence frequency of noise before correction to the correction part 232 together with the identification information.In step S 5, the correction element 232 extracts correction information that matches or is similar to the operating conditions of the machining apparatus 100 included in the information on the conditions. The correction element 232 corrects the occurrence frequency of noise before correction to the occurrence frequency of noise after correction using the correction amount included in the extracted correction information. For example, the correction element 232 extracts correction information indicating conditions in which the temperature and / or humidity at the location where the machining apparatus 100 is installed are the same or similar, and corrects the frequency of occurrence of disturbances before the correction with the correction amount included in the extracted correction information to the frequency of occurrence of disturbances after the correction. In addition, the correction element 232 extracts, for example, correction information indicating conditions that are the same or similar with respect to the rotation state of the motor of the machining apparatus 100, and corrects the occurrence frequency of disturbances before correction with the correction amount included in the extracted correction information to the occurrence frequency of disturbances after correction. The correction element 232 transmits the occurrence frequency of failures after the correction to the intermediate server 10 together with the identification information.In step S 6, the notification information generation unit 14 judges, for each processing device 100 identified from the identification information, whether or not the occurrence frequency of failures after correction exceeds a predetermined threshold. When the occurrence frequency of failures after the correction exceeds the predetermined threshold (step S 6: YES), the notification information generation unit 14 generates notification information as a result of the judgment, and sends it to the machining apparatus 100 identified from the identification information. Then, after retrieving the notification information in step S 7, the notifying element 104 outputs the retrieved notification information. Then, the operation of the management system 1 ends.On the other hand, when the frequency of occurrence of failures of the machining device 100 identified from the identification information after the correction does not exceed the predetermined threshold (step S 6: NO), the notification information generation unit 14 does not output the notification information to the machining device 100 identified from the identification information as a result of the judgment. Then, the operation of the management system 1 ends.With the management system 1 relating to the above first embodiment of the present invention, the following results are obtained. (1) The management system 1 includes: the duration information generation element 102 that generates duration information including the setup duration and the operation duration of the machining apparatus 100; the condition information generation element 103 that generates condition information based on the setup conditions and / or operation conditions of the machining apparatus 100; the retrieval unit 11 that retrieves duration information and condition information to each machining apparatus 100; the analysis unit 23 that analyzes the frequency of occurrence of failures based on the duration information and the condition information and the coolant-caused failure information of the machining apparatus 100; and the notification information generation unit 14 that outputs notification information based on the occurrence frequency of failures. Since the occurrence frequency of failures is analyzed using the duration information and the condition information and the occurrence information of failures, it is possible to analyze the occurrence frequency of failures not only based on the setup duration and operation time of the machining apparatus 100 but also based on the setup conditions and the operation conditions of the machining apparatus 100. Thereby, similarly, compared to a case of analyzing the occurrence frequency of failures based only on the information on the duration, it is possible to improve the accuracy of predicting the occurrence frequency of failures of the machining apparatuses 100. In addition, by outputting the information for notification in a case where the abnormality occurrence frequency exceeds the predetermined threshold, processing of cases where an abnormality has occurred in the processing apparatus 100 to which the information for notification has been output becomes possible at the initial stage. Moreover, it is possible to reduce the uneconomical general maintenance of processing apparatuses 100 for which the same type of coolant is used. (2) The analysis unit 23 includes the calculation part 231 that compares the abnormality occurrence information with the duration information and then calculates the abnormality occurrence frequency for each machining device 100; and the correction part 232 that corrects the abnormality occurrence frequency calculated by the calculation part 231 to the abnormality occurrence frequency for each machining device 100 on the basis of the condition information. Thereby, it is possible to correct the occurrence frequency of failures using the differences between the occurrence frequencies of failures caused by coolant based on the setup conditions and the operation conditions of the machining apparatus 100. As a result, it is possible to specifically determine the frequency of occurrence of faults predicted for each machining device 100. (3) The correction element 232 corrects the occurrence frequency of failures using the temperature and the humidity of the environment surrounding the processing device 100 on the basis of the placement location of the processing device 100. It is possible to correct the frequency of occurrence of noise in consideration of the influence of chemical changes due to coolant using the temperature and humidity of the environment surrounding the processing apparatus 100. Therefore, it is possible to further improve the accuracy of prediction of the occurrence frequency of failures for each machining apparatus 100. (4) The retrieval unit 11 retrieves duration information and condition information from another one of the processing devices 100 among the processing devices 100 of the same type in the event of occurrence of failure of one among the processing devices 100 of the same type. Thereby, it is possible to acquire information on duration and information on conditions to another machining device 100 of the same type, and analyze the occurrence frequency of failures of machining devices 100 of the same type that is closer to the occurrence time of failure by the occurrence of the trigger of failure in one of the machining devices 100 of the same type. Therefore, it is possible to output information for notification based on a malfunction occurrence frequency corresponding to the present conditions.(Second Embodiment)Next, referring to FIGS. 8 to 10, a management system 1 according to a second embodiment of the present invention will be explained. In the explanation of the second embodiment, identical constituent elements are denoted by the same reference numerals, and their explanation is omitted or simplified. In the management system 1 according to the second embodiment, the intermediate server 10 further includes, as shown in FIG. 8, an association unit 15.The allocation unit 15 acquires frequencies of occurrence of interference after correction to each of the machining apparatuses 100 from the correction elements 232. The associating unit 15 associates each of the machining apparatuses 100 of the same type with the total load amount of the machining apparatuses 100. The mapping unit 15 performs mapping from a processing device 100 with a low frequency of occurrence of disturbances after correction in the order of higher loads.For example, the allocation unit 15 reduces the load for the machining apparatuses 100 in which a frequency of occurrence of interference after correction of 80% and 50% has been found, as shown in FIG. 10. In addition, the allocation unit 15 increases the load for the machining apparatuses 100 in which a frequency of occurrence of disturbances after the correction of 3% and 5% has been found. The allocating unit 15 allocates the decreased amount of load for machining apparatuses 100 with a high occurrence frequency of disturbances after correction as an increased amount of load to machining apparatuses 100 with a low occurrence frequency of disturbances after correction. The associating unit 15 generates load information indicating the load magnitude for each machining device 100. The associating unit 15 transmits the generated load information to each of the machining apparatuses 100.The operation control part 105 controls the operation of the machining apparatus 100 on the basis of the transmitted load information. The operation control part 105 controls, for example, the number of machining processes of the machining apparatus 100. The operation control part 105 controls, for example, the operation time, the frictional load, etc. of the machining apparatus 100 as the number of machining processes.With the management system 1 relating to the above second embodiment of the present invention, the following results are obtained.(5) The management system 1 further includes the allocation unit 15 that allocates the total load amount of the plurality of machining apparatuses 100 to each of the machining apparatuses 100 according to the occurrence frequency of failures. Since it is possible to assign the total load magnitude to the machining devices 100 according to the times of occurrence of disturbances, the load of machining devices 100 can be reduced with a high frequency of occurrence of disturbances without a reduction in the total load. Therefore, it is possible to take time for preparation until maintenance of a machining apparatus 100 with a high frequency of occurrence of failures.Although the respective preferred embodiments of the management system according to the present invention have been explained above, the present invention is not to be limited to the above-discussed embodiments, and modifications are possible as appropriate.In the above-discussed embodiments, the retrieval unit 11 is configured to retrieve, in the event of occurrence of failure of any of the machining apparatuses 100, information on duration and information on conditions of each of the machining apparatuses 100 of the same type for which the same type of coolant is used; however, there is no limitation thereto. For example, the retrieval unit 11 may periodically retrieve information on duration and information on conditions from each of the processing devices 100 of the same type for which the same type of coolant is used. As a result, since it is possible to always grasp a processing device 100 with a high frequency of occurrence of failures, it is possible to perform maintenance and inspection of the processing devices 100 before the occurrence of failure.In addition, in the above-discussed embodiments, the retrieval unit 11 is configured to retrieve identification information from the processing device 100; however, there is no limitation thereto. The retrieval unit 11 can retrieve identification information about the machining devices 100 by, for example, identifying the port number or the like of the machining devices 100 connected to the intermediate server 10.In addition, in the above-discussed embodiment, the analysis unit 23 may further include an update unit (not illustrated) that updates other correction information stored in the correction information database 22 when a condition under which a failure occurs is further included in the information on the conditions transmitted from the processing device 100. The update unit retrieves the frequency of occurrence of failures before correction calculated by the calculation element 231 for a machining apparatus 100 in which a failure has occurred. The update unit defines the difference between the frequency of occurrence of interference before correction and 100% as a correction amount, and generates correction information that associates the correction amount with the information on the conditions of the machining apparatus 100 in which interference has occurred. The update unit stores the generated correction information as new correction information in the correction information database 22.Thereby, it is possible to collect correction information concerning examples in which a disturbance has occurred after the correction. Therefore, it is possible to further improve the accuracy of correction of the occurrence frequency of disturbances after the correction.In addition, in the above-discussed embodiments, the correction information database 22 is configured to store the correction information indicating the correction amount for the frequency of occurrence of noise. In addition, the correction element 232 is configured to calculate the occurrence frequency of disturbances after the correction by correcting the occurrence frequency of disturbances before the correction. Instead, the correction information for correcting the operation time may be stored in the correction information database 22. In addition, the correction element 232 may correct the operation time included in the duration information based on the correction information. The calculation part 231 may calculate the occurrence frequency of noise after correction based on the corrected operation time.In addition, in the above-discussed embodiments, abnormality occurrence information for each type of refrigerant may be stored in the correction information database 22. The retrieval unit 11 may retrieve the duration information, the operation information, and the identification information from each of different processing apparatuses 100 for which different refrigerants are used. Then, the duration information organization unit 12 may organize the duration information and the identification information for each processing apparatus 100 of the same type for which the same type of coolant is used. In addition, the condition information organization unit 13 may organize the condition information and the identification information for each processing apparatus 100 of the same type for which the same type of coolant is used.The whole or parts of the various servers included in the present invention may be realized by hardware, software, or a combination thereof.
