[0023] Returning to Figure 1, establishment 3 refers to an individual location where the production of goods or the provision of services is carried out as a business. Industrial equipment 2 is installed in establishment 3. Establishments 3 that produce goods, etc. have factories 4. Examples of factories 4 include food factories, beverage factories, metal product factories, plastic product factories, textile factories, and laundry factories. Industrial equipment 2 is installed in factories 4.

[0024] It should be noted that the establishment 3 that provides the service does not necessarily have to have a factory 4. The business conducted at the establishment 3 may include public health services. Examples of public health services include hospitals, clinics, and health centers. The establishment 3 may also include a food service center. The industrial equipment 2 may be installed on a ship used for maritime transportation services instead of the establishment 3.

[0025] In the example shown in FIG. 1, there are three business establishments 3 operated by a certain business operator. The business establishments 3 include a first business establishment 3A, a second business establishment 3B, and a third business establishment 3C. A factory 4 is set up in the second business establishment 3B. The factory 4 set up in the second business establishment 3B includes a first factory 4A and a second factory 4B. Note that a factory 4 may be set up in one or both of the first business establishment 3A and the third business establishment 3C.

[0026] The industrial equipment 2 is installed in each of the first factory 4A and the second factory 4B. The data collection terminal 7 is installed in each of the first factory 4A and the second factory 4B. The data collection terminal 7 is a general term for devices in the business establishment 3 that are used for data collection.

[0027] The industrial equipment operation support system 1 comprises a plurality of environmental sensors 5 arranged in the industrial equipment 2, a plurality of controllers 61 equipped in the industrial equipment 2, and a plurality of information processing devices 6 configured to acquire and store environmental information detected by the environmental sensors 5 and operation information generated by the controllers 61.

[0028] The environmental sensors 5 detect environmental information of the industrial equipment 2. The environmental information of the industrial equipment 2 refers to the environmental state or conditions of the space in which the industrial equipment 2 operates. The environmental information of the industrial equipment 2 includes environmental information of the business establishment 3 (factory 4) where the industrial equipment 2 is installed. The environmental information includes physical parameters of the industrial equipment 2 itself and its surroundings. Data detected by some of the environmental sensors 5 is used for the operation or control of the industrial equipment 2. Examples of environmental sensors 5 include temperature sensors, humidity sensors, pressure sensors, water level sensors, flow rate sensors, electrical conductivity sensors (EC sensors), power sensors, distance sensors, image sensors, and force sensors.

[0029] The environmental sensor 5 is connected to a controller 61 of the industrial equipment 2 and a controller 61 of the data collection terminal 7, respectively.

[0030] As shown in FIG. 2, the environmental sensor 5 is provided on the supply route 21 (on the primary utility side). The environmental sensor 5 is provided on the transport route 22 (on the secondary utility side). The environmental sensor 5 may be disposed closer to the industrial facility 2 or closer to the demand facility 8 on the transport route 22. The environmental sensor 5 may also be disposed on the discharge route 23 (downstream of the demand facility 8).

[0031] In an embodiment, the environmental information of the industrial facility 2 detected by the environmental sensor 5 includes input energy information and output energy information of the industrial facility 2. The input energy information includes the input amount of a primary utility. The output energy information includes the output amount of a secondary utility. The environmental information includes actual quality level information of a medium or item produced by the industrial facility 2.

[0032] The controller 61 has the function of controlling the operation of the industrial equipment 2 and controlling data collection. The controller 61 is mainly used to control the operation of machinery and equipment (heat equipment, water treatment equipment, water quality measurement equipment, etc.). The controller 61 is connected to an environmental sensor 5 attached to the machinery and equipment. The controller 61 may also be configured as part of a data collection terminal 7 that is specialized in collecting information from an environmental sensor 5 that is not attached to the machinery and equipment (an environmental sensor that is attached to the machinery and equipment later, or attached to a piping network, etc.).

[0033] The controller 61 is incorporated into the industrial equipment 2 and the data collection terminal 7. Examples of the controller 61 incorporated into the industrial equipment 2 include a microcomputer 61A (microcomputer) and a programmable logic controller 61B (PLC). In the embodiment, the industrial equipment 2 includes a first industrial equipment 2A in which the microcomputer 61A is installed, and a second industrial equipment 2B in which the programmable logic controller 61B is installed. Examples of the controller 61 incorporated into the data collection terminal 7 include the microcomputer 61A.

[0034] The controller 61 of the industrial equipment 2 uses the environmental information collected from the environmental sensors 5 to control the operation of the industrial equipment 2 and records it for operational management. Note that the controller 61 of the industrial equipment 2 may receive environmental information collected by a controller 61 incorporated in another industrial equipment 2 or the data collection terminal 7 and use it to control the operation of its own equipment.

[0035] The controller 61 of the data collection terminal 7 is connected to each of the plurality of environmental sensors 5 scattered throughout the establishment 3. The controller 61 of the data collection terminal 7 is connected to the plurality of environmental sensors 5 of different types.

[0036] The controller 61 generates operation information of the industrial equipment 2. The controller 61 may generate the operation information of the industrial equipment 2 based on detection data of the environmental sensor 5. In the embodiment, the operation information of the industrial equipment 2 generated by the controller 61 includes the operation time of the industrial equipment 2 and whether or not there is an abnormality in the industrial equipment 2. The operation information includes actual operation time information linked to the normal state of the industrial equipment 2 and non-operation time information linked to the abnormal state. The operation information includes whether the condition of the industrial equipment 2 is good or bad. The operation information includes an abnormality notification signal that is transmitted by the controller 61 when a malfunction occurs in the industrial equipment 2.

[0037] The condition of the industrial equipment 2 is detected by the environmental sensor 5. For example, when the condition of the industrial equipment 2 deteriorates, the detected value of the environmental sensor 5 is often a numerical value that deviates from the detected value of the environmental sensor 5 when the condition of the industrial equipment 2 is normal. Therefore, for example, multiple thresholds are set according to the deviation level of the detected value of the environmental sensor 5 from the normal value, and the controller 61 is configured to detect that there is a sign of an abnormality when the deviation level reaches a lower first threshold, and that an abnormality has occurred when the deviation level reaches a higher second threshold.

[0038] If the industrial equipment 2 is a steam boiler, the operation information relating to the condition includes scale adhesion information based on the water pipe temperature, feedwater pump performance information based on water level control inside the boiler, etc. If the industrial equipment 2 is a heat pump or chiller, the operation information relating to the condition includes refrigerant leak detection information, differential pressure information between the condenser and evaporator, etc. If the industrial equipment 2 is an air compressor, the operation information relating to the condition includes lubricant deterioration detection information, differential pressure information for filters, etc. If the industrial equipment 2 is an RO membrane device, the operation information relating to the condition includes permeation flux information of the membrane element, water quality information for the permeate, etc.

[0039] [2] Information processing device The industrial facility operation support system 1 has a plurality of information processing devices 6. The information processing devices 6 include a controller 61, an edge computer 62, a gateway 63, a guest computer 64, and a host computer 65.

[0040] 3 is a hardware configuration diagram showing an information processing device 6 according to an embodiment. The information processing device 6 includes a computer 10. Each of a controller 61, an edge computer 62, a gateway 63, a guest computer 64, and a host computer 65 includes a computer 10. The computer 10 includes a processor 11, a storage device 12, a communication interface 13, and an input / output interface 14. The information processing device 6 also includes a power supply device (not shown).

[0041] The processor 11 includes a CPU (Central Processing Unit). The processor 11 may also include a GPU (Graphics Processing Unit). The storage device 12 includes a recording medium that stores computer programs and data in a manner that allows the processor 11 to read them. The storage device 12 includes on-board system memory such as RAM (Random Access Memory) or ROM (Read Only Memory), large-capacity flash memory such as an SD card or USB memory, and large-capacity storage such as an HDD (Hard Disk Drive) or SSD (Solid State Drive).

[0042] The communication interface 13 communicates via a communication network. Examples of communication networks include a local area network (LAN), a wide area network (WAN), and a commercial network such as the Internet. The local area network may be a wired LAN or a wireless LAN. The wide area network may include a mobile line or a satellite communication line. The computer 10 transmits data to an external computer via the communication network. The computer 10 receives data from an external computer via the communication network. The computer 10 is connected to an external device via the input / output interface 14.

[0043] The storage device 12 stores various software programs (engines and applications, which will be described later). The processor 11 reads the software programs from the storage device 12, loads them into the system memory, and executes processing in accordance with the software programs. In other words, the processor 11 can also be considered to have multiple functional units, such as engines. The functions of the engines and the like of the processor 11 are realized by the software programs. The software programs may be distributed to the computer 10 via a communication network.

[0044] A software program that realizes a specific function on a computer is called an engine, and the functional unit of an engine is called a module. An engine may be installed on a computer as a single software package with all functions, but it is preferable that each functional unit of the engine is installed on a computer as a separate software module. If the functional unit of the engine is modularized, it becomes easier to update when functional modifications are made. Note that a software program prepared to allow an end user (mainly a customer who uses equipment) to perform a specific task on a computer is called an application, and can be distinguished from an engine in terms of purpose.

[0045] The environmental sensors 5 are connected to the input / output interface 14 of the controller 61. A plurality of environmental sensors 5 are connected to one controller 61. The controller 61 collects environmental information in real time from the environmental sensors 5. The communication interface 13 of the controller 61 transmits the real-time environmental information and real-time operation information to the edge computer 62 via a communication network (LAN).

[0046] The edge computer 62 is installed in the factory 4. One or more edge computers 62 are installed in one factory 4. The communication interface 13 of the edge computer 62 communicates with each of the multiple controllers 61 belonging to the factory 4 in which the edge computer 62 is located via a communication network (LAN). The edge computer 62 receives environmental information and operation information from the controllers 61 via the communication network.

[0047] The edge computer 62 has about 5 GB of on-board memory as the storage device 12 so that it can store a sufficient amount of information. The edge computer 62 may also have an AI engine (neural network processing unit: NPU) so that it can execute the learning phase and inference phase in machine learning.

[0048] The gateway 63 constitutes a connection node between the local area network and the Internet, and has performance and specifications equivalent to those of the edge computer 62. The gateway 63 is installed at the business establishment 3. One or more gateways 63 are installed at one business establishment 3. The communication interface 13 of the gateway 63 communicates with each of the multiple edge computers 62 belonging to the business establishment 3 where the gateway 63 is located via a communication network (LAN). The gateway 63 receives environmental information and operation information from the edge computer 62 via the communication network. Note that if the factory 4 installed at the business establishment 3 is a single building, the edge computer 62 and gateway 63 may be integrated into a single computer.

[0049] The guest computer 64 is located outside the business establishment 3. The guest computer 64 is installed, for example, at a regional base of a service provider that undertakes tasks such as status monitoring and maintenance inspection of industrial equipment 2 installed at the business establishment 3. One guest computer 64 is installed at each management base. The guest computer 64 includes a local server. The communication interface 13 of the guest computer 64 communicates with a gateway 63 belonging to the business establishment 3 via a communication network (Internet). The guest computer 64 receives environmental information and operation information from the gateway 63 via the communication network. If a guest computer 64 is not installed, the gateway 63 and a host computer 65, which will be described later, will be connected via a communication network.

[0050] The host computer 65 is located outside the business establishment 3. The host computer 65 is installed, for example, at the headquarters of a service provider. The host computer 65 includes a cloud server. The communication interface 13 of the host computer 65 communicates with each of the multiple guest computers 64 via a communication network (the Internet). The host computer 65 receives environmental information and operation information from the guest computers 64 via the communication network.

[0051] [3] Hierarchical structure 4 is a diagram illustrating an information processing device 6 according to an embodiment. The multiple information processing devices 6 have a hierarchical structure in which environmental information detected by the environmental sensor 5 and operation information generated by the controller 61 are transmitted from downstream to upstream. Of the multiple information processing devices 6, the controller 61 to which the environmental sensor 5 is connected is the most downstream (lower layer, lower) information processing device 6, the edge computer 62 is the downstream information processing device 6 next to the controller 61, the gateway 63 is the downstream information processing device 6 next to the edge computer 62, the guest computer 64 is the downstream information processing device 6 next to the gateway 63, and the host computer 65 is the most upstream (upper layer, upper) information processing device 6.

[0052] The information processing devices 6 are connected to each other via a communication network. A local area network is used as the communication network inside the building or ship, while a commercial wide area network such as the Internet or a mobile phone line is used as the communication network outside the building or ship. Satellite communication is used for communication between the ship and land.

[0053] Environmental information is detected by the environmental sensors 5. The controller 61, which is a lower-level information processing device in the hierarchical structure, acquires real-time environmental information from the environmental sensors 5. The real-time environmental information detected by the environmental sensors 5 and collected by the controller 61 is transmitted from the controller 61 to the edge computer 62 via the communication network. In addition, real-time operation information generated by the controller 61 is also transmitted from the controller 61 to the edge computer 62 via the communication network. The environmental information and operation information transmitted to the edge computer 62 are transmitted from the edge computer 62 to the gateway 63 via the communication network. The environmental information and operation information transmitted to the gateway 63 are transmitted from the gateway 63 to the guest computer 64 via the communication network. The environmental information and operation information transmitted to the guest computer 64 are transmitted from the guest computer 64 to the host computer 65 via the communication network.

[0054] The controller 61 is a lower information processing device in the hierarchical structure. The edge computer 62, the gateway 63, and the guest computer 64 are intermediate information processing devices in the hierarchical structure. The host computer 65 is a higher information processing device in the hierarchical structure.

[0055] The lower information processing device functions as an IoT device to which an environmental sensor 5 is connected. The lower information processing device can transmit various environmental information and operation information to the intermediate information processing device. The intermediate information processing device functions as a relay between the lower information processing device and the upper information processing device. The intermediate information processing device can receive various environmental information and operation information from the lower information processing device and transmit the various environmental information and operation information to the upper information processing device. The upper information processing device can receive various environmental information and operation information from the intermediate information processing device. The upper information processing device has an information accumulation platform. The information accumulation platform is, for example, an open IoT operating system based on cloud computing, and is capable of systematically accumulating information aggregates, etc., as described below. Note that some or all of the functions realized by the information accumulation platform may be incorporated into the intermediate information processing device.

[0056] [4] Information processing device 5 is a functional block diagram showing an information processing device 6 according to an embodiment. As shown in FIG. 2, the information processing device 6 includes a computer 10 having a processor 11. The information processing device 6 includes an information processing engine 31, a useful information generation engine 32, a UI provision engine 33, a performance value prediction engine 34, a maintenance plan engine 35, a treatment content extraction engine 36, an information accumulation platform 37, and a database 38. Note that the database 38 may be a group of databases that handle a wide variety of information, or may be a component of the information accumulation platform 37.

[0057] A user terminal 40 is connected to the information processing device 6. Examples of the user terminal 40 include a personal computer, a tablet terminal, and a smartphone. The user terminal 40 includes a display device such as a liquid crystal display or an organic EL display.

[0058] The multiple information processing devices 6 (61, 62, 63, 64, 65) have, at one or more levels, an information processing engine 31, a useful information generation engine 32, a UI providing engine 33, a performance value prediction engine 34, a maintenance plan engine 35, a treatment content extraction engine 36, an information accumulation platform 37, and a database 38. That is, each of the information processing engine 31, the useful information generation engine 32, the UI providing engine 33, the performance value prediction engine 34, the maintenance plan engine 35, the treatment content extraction engine 36, the information accumulation platform 37, and the database 38 can be a functional unit at one or more levels of the multiple information processing devices 6 (61, 62, 63, 64, 65).

[0059] It is preferable that the information processing engine 31 is a functional part of an edge computer 62 or a gateway 63, and it is preferable that the useful information generation engine 32, the UI provision engine 33, the performance value prediction engine 34, the maintenance planning engine 35, the treatment content extraction engine 36, the information accumulation platform 37, and the database 38 are functional parts of a host computer 65.

[0060] <4-1> Information processing engine The information processing engine 31 executes predetermined information processing on the acquired environmental information and operation information. The information processing executed by the information processing engine 31 includes batch processing that adjusts the time-series environmental information and operation information to a required time granularity. The information processing executed by the information processing engine 31 includes grouping processing that integrates multiple different types of environmental information and operation information into an information aggregate linked to a hierarchical level of industrial activity.

[0061] (4-1-1) Generation and processing of real-time environmental information and real-time operation information The generation process of the real-time environmental information and the real-time operation information is performed by the information processing engine 31 of the lower-level information processing device. Note that the generation process of the real-time environmental information and the real-time operation information may be performed by the information processing engine 31 of the intermediate information processing device or the information processing engine 31 of the higher-level information processing device.

[0062] The information processing engine 31 acquires and stores real-time environmental information at predetermined sampling intervals from the environmental sensor 5. The information processing engine 31 has an A / D conversion function that converts the analog signal of the environmental sensor 5 into a digital signal, a function that replaces the A / D value with a measurement sample value, a function that selects and rejects the measurement sample value, a moving average function of the measurement sample value, a period or frequency measurement function of a pulse signal, and the like, and calculates a final measurement value in real time using these functions.

[0063] If the environmental sensor 5 is a temperature sensor, pressure sensor, or water level sensor, the information processing engine 31 reads the analog signal of the environmental sensor 5 at a predetermined sampling interval (approximately 10 to 25 ms), quantizes it, and converts it into a digital signal to calculate an A / D value. The information processing engine 31 processes the most recent N sampling results at each sampling timing, and determines the average of the A / D values ​​for M (=N-4) samples, excluding the first and second largest values ​​and the first and second smallest values, as the final A / D value. The information processing engine 31 generates the temperature, pressure, or water level as real-time environmental information from the final A / D value by referring to a judgment table or using a calculation formula. The information processing engine 31 also determines whether the environmental sensor 5 is normal or abnormal based on the final A / D value.

[0064] If the environmental sensor 5 is a flow sensor, the information processing engine 31 measures the interval between the falling edge and the next falling edge of a pulse signal obtained by converting a sine wave signal into a square wave signal as the pulse width. The pulse width is counted with the period of the count clock as one unit. The information processing engine 31 updates the pulse width at predetermined sampling intervals (approximately 100 ms) and calculates a sample value of the instantaneous flow rate by dividing a pulse constant (L / P: number of liters per pulse) by the pulse width. The information processing engine 31 processes the most recent N sampling results at each sampling timing and generates the latest instantaneous flow rate as real-time environmental information from the average of M (=N-2) samples excluding the maximum and minimum values. The information processing engine 31 detects the number of times the falling edge of the pulse signal is detected every second as the pulse count (P / s). When the pulse count is updated, the information processing engine 31 adds the flow rate calculated by multiplying the pulse count by the pulse constant to the previous integrated flow rate to generate the latest integrated flow rate as real-time environmental information.

[0065] If the environmental sensor 5 is an EC sensor, the information processing engine 31 calculates a determined A / D value using the same process as for a temperature sensor, and calculates a calculated electrical conductivity value by applying a predetermined formula depending on the range of the determined A / D value. Furthermore, the information processing engine 31 applies a correction coefficient for correcting for variations in individual sensors and temperature data measured by the temperature sensor to generate electrical conductivity converted to 25°C as real-time environmental information.

[0066] If the environmental sensor 5 is a power sensor (power monitor), the information processing engine 31 acquires sample values ​​of instantaneous power from the power sensor at a predetermined sampling period (approximately 80 to 100 ms), adds (sums) all sample values ​​for one period at each sampling interval Δt, and averages them over the period T to obtain real-time environmental information of instantaneous power [W]. The instantaneous power for each sampling period is accumulated to obtain real-time environmental information of integrated power, and if one period is one second, the unit of this accumulated value is [W·s], and if this is multiplied by 3600, the unit becomes [W·h].

[0067] The information processing engine 31 acquires and accumulates real-time operation information from the controller 61 at predetermined sampling intervals. For example, the controller 61 transmits an operating signal when the industrial equipment 2 is operating normally, and transmits an abnormality stop signal when the industrial equipment 2 has stopped due to an abnormality. The information processing engine 31 measures the uptime (actual operating time information) of the industrial equipment 2 in real time using the operating signal received via the input / output interface 14. The information processing engine 31 also measures the downtime (non-operating time information) of the industrial equipment 2 in real time using the abnormality stop signal received via the input / output interface 14.

[0068] The time granularity of the real-time environmental information and real-time operation information depends on the sampling interval or recording interval and is generally quite fine (for example, the latest value is updated every 10 ms to 1 s). When multiple types of real-time environmental information are used to calculate other information (real-time values ​​such as boiler efficiency, differential pressure, and permeation flux) at the time of updating the real-time environmental information, the information processing engine 31 also treats the other information as real-time environmental information. The information processing engine 31 transmits the real-time environmental information together with an identification number (measurement item ID, device ID, location ID, etc.) and the update time to the upper information processing device 6.

[0069] (4-1-2) Batch processing The real-time environmental information and real-time operation information are time-series data that are generated successively over time by the information processing engine 31. Batch processing refers to the process of adjusting the time-series real-time environmental information and real-time operation information to the required time granularity. Time granularity is an index that indicates the degree of time granularity, and can be selected from, for example, seconds, minutes, hours, and days. In the following explanation, environmental information and operation information that have undergone batch processing may be referred to as "batch environmental information" and "batch operation information."

[0070] When batch processing is performed in the information processing engine 31 of the lower-level information processing device, the controller 61 includes a microcomputer 61A and a programmable logic controller 61B, so it is preferable to perform batch processing taking into account the difference in processing capabilities. For example, the microcomputer 61A, due to its high processing capabilities, can provide real-time environmental information and real-time operation information with finer time granularity than the programmable logic controller 61B. Therefore, it is preferable for the microcomputer 61A to perform batch processing in accordance with the programmable logic controller 61B, which has a coarser time granularity.

[0071] When batch processing is performed in the information processing engine 31 of the intermediate information processing device, the edge computer 62 acquires real-time environmental information from the controller 61 at predetermined intervals, accumulates it for a predetermined period, performs batch processing, and processes it into batch environmental information with adjusted time granularity. The intermediate information processing device continuously collects and integrates real-time environmental information, for example, at one-second intervals. If the real-time environmental information is temperature, pressure, instantaneous flow rate, or the like, the information processing engine 31 of the intermediate information processing device divides the integrated value of the real-time environmental information by the number of integrations to calculate an average value when the predetermined period is reached, and uses the calculated average value as the batch environmental information. If the real-time environmental information is an integrated flow rate or power consumption per unit time period, the information processing engine 31 of the intermediate information processing device uses the integrated value of the real-time environmental information as the batch environmental information as is. When processing the integrated real-time environmental information into batch environmental information, the information processing engine 31 of the intermediate information processing device also treats other information (COP, specific energy, etc.) calculated using multiple types of batch environmental information as batch environmental information.

[0072] Furthermore, when batch processing is performed in the information processing engine 31 of the upper information processing device instead of the intermediate information processing device, real-time environmental information transmitted from the information processing engine 31 of the lower information processing device to the information processing engine 31 of the intermediate information processing device is acquired at predetermined intervals, accumulated for a predetermined period, and batch-processed into batch environmental information with adjusted time granularity. The contents of the batch processing can be the same as those when performed in the information processing engine 31 of the intermediate information processing device.

[0073] Batch operation information is, for example, real-time operation information that has been subjected to threshold processing at a required time granularity. For example, the combustion stage of a steam boiler may be subjected to threshold processing at a predetermined interval, or the rotational load factor of an air compressor may be subjected to threshold processing at a predetermined interval.

[0074] The time granularity of batch environmental information and batch operation information is preferably at a level that can be used to calculate or evaluate at least the operation performance value, energy performance value, quality performance value, and overall score value described below in the information utilization process associated with providing services to customers, and is selected from, for example, 0.5 hours, 1 hour, 2 hours, 6 hours, 12 hours, or 24 hours. Batch environmental information and batch operation information with this level of time granularity can also be used for optimization diagnostic simulations of industrial machinery or production equipment (reviewing control settings and control patterns, predicting the effects of equipment modifications, etc.). Note that the calculation or evaluation of energy performance values ​​may be accompanied by the calculation or evaluation of environmental impacts (carbon dioxide emissions, hazardous substance emissions, etc.).

[0075] (4-1-3) Grouping process Grouping processing refers to the process of integrating multiple different types of environmental information and operation information (real-time environmental information, batch environmental information, real-time operation information, batch operation information) into an information aggregate linked to the hierarchical level of industrial activity.

[0076] As shown in FIG. 4, the hierarchical levels of industrial activities include one or more of a machine unit level, a machine group level, a cell level, a line level, a building level, and a business establishment level.

[0077] The individual machine level is a level at which the operation performance value, energy performance value, quality performance value, and overall score value, which will be described later, are managed for each individual unit of industrial equipment 2 such as a steam boiler, heat pump, or air compressor.

[0078] The machine group level is a level at which the operation performance value, energy performance value, quality performance value, and overall score value are managed for multiple installations of industrial equipment 2 such as steam boilers, heat pumps, and air compressors.

[0079] The cell level is a level at which the operation performance value, energy performance value, quality performance value and overall score value of distributed installation type industrial equipment 2 attached to one or more cells are managed at a site where the cell production method is adopted.

[0080] The line level is a level at which the operation performance value, energy performance value, quality performance value, and overall score value of distributed industrial equipment2 attached to one or more lines (such as a container molding line or a beverage filling and sterilization line in a beverage manufacturing plant) at a site that uses the line production method are managed.

[0081] The building level is a level at which the operation performance value, energy performance value, quality performance value and overall score value of industrial equipment 2 are managed for building units (units of first factory 4A, units of second factory 4B) dispersed within the site of business establishment 3.

[0082] The facility level is a level at which the operation performance value, energy performance value, quality performance value and overall score value of the industrial equipment 2 are managed for the entire site of the facility 3 (both the first factory 4A and the second factory 4B).

[0083] When grouping is performed in the information processing engine 31 of the upper information processing device (host computer 65), the information processing engine 31 of the upper information processing device selects and groups multiple pieces of batch environment information and batch operation information required for calculating or evaluating operation performance values, energy performance values, quality performance values, and overall scores from the diverse batch environment information and batch operation information generated by the edge computer 62. The information aggregate that has undergone this grouping process is accumulated in the information accumulation platform for a period required for history management (for example, the past 12 months). The information aggregate may also be one that has been selected and grouped for multiple pieces of batch environment information and batch operation information required for demand management of utilities (hot water, steam, compressed air, treated water) of demand facilities 8.

[0084] When grouping processing is performed in the information processing engine 31 of the intermediate information processing device (edge ​​computer 62), the information processing engine 31 of the edge computer 62 can perform the grouping processing while performing the above-mentioned batch processing. The content of the grouping processing can be the same as that performed by the information processing engine 31 of the upper information processing device.

[0085] The time granularity of each batch environment information and batch operation information that make up an information collection is basically the same, and each information collection is accompanied by information on the accumulation period of the real-time environment information that forms the basis of the batch environment information and the real-time operation information that forms the basis of the batch operation information.

[0086] An example of grouping processing will be described below. The information processing engine 31 of the host information processing device performs grouping processing of batch environment information for the purpose of performing energy management of heat recovery air compressors, demand management of heat recovery air compressors, energy management of heat pumps, demand management of heat pumps, energy management of steam boilers, and demand management of steam boilers. The batch environment information that has undergone grouping processing is accumulated in the information accumulation platform 37. The time granularity of the batch environment information that is the subject of grouping processing is, for example, in 30-minute increments or 1-hour increments.

[0087] (4-1-3-1) Energy management of heat recovery air compressors The heat recovery air compressor is equipped with a heat recovery heat exchanger that recovers the heat of compression contained in the compressed air and lubricating oil to generate hot water from cooling water. The information processing engine 31 of the intermediate information processing device acquires real-time environmental information corresponding to each sensor from a lower information processing device connected to a temperature sensor, a flow rate sensor, a power sensor, etc., and generates batch environmental information. The batch environmental information includes information such as the discharge air volume [m 3 / h], power consumption [kWh], average inlet water temperature [℃], average outlet hot water temperature [℃], and cumulative hot water volume [m 3 The host information processing device generates an information aggregate by grouping these multiple types of batch environment information. The information processing engine 31 of the host information processing device calculates the specific energy [kW / m 3 ] and energy recovery rate [%] are calculated.

[0088] (4-1-3-2) Demand management of heat recovery air compressor The information processing engine 31 of the intermediate information processing device acquires real-time environmental information corresponding to the sensors from the lower information processing device to which the flow rate sensor and the contact signal output device of the air supply valve are connected, and generates batch environmental information. The batch environmental information includes information such as the discharge air volume [m 3 / h], air consumption [m 3 / h], and the cumulative open time [h] of the air supply valve. The information processing engine 31 of the host information processing device generates an information aggregate by grouping these multiple types of batch environment information. The information processing engine 31 of the host information processing device calculates the availability rate [%] of the demand equipment using the batch environment information integrated in the information aggregate. The information processing engine 31 of the host information processing device also diagnoses the presence or absence of leak loss in the air transport piping network by comparing the discharge air volume and consumed air volume integrated in the information aggregate. The air supply valve is provided at the end of the air transport piping and is opened when compressed air is used in the load equipment.

[0089] (4-1-3-3) Energy management of heat pumps The machinery and equipment to be managed includes air-source heat pumps and water-source heat pumps. The information processing engine 31 of the intermediate information processing device acquires real-time environmental information corresponding to each sensor from a lower information processing device connected to a temperature sensor, a flow rate sensor, and a power sensor, and generates batch environmental information. The batch environmental information includes the average inlet water temperature [°C], the average outlet hot water temperature [°C], the cumulative hot water volume [m 3 ], power consumption [kWh], and average heat source temperature [°C]. The information processing engine 31 of the host information processing device generates an information aggregate by grouping these multiple types of batch environment information. The information processing engine 31 of the host information processing device calculates the coefficient of performance (COP) and heat supply amount [W] using the batch environment information integrated into the information aggregate.

[0090] (4-1-3-4) Demand management of heat pumps When hot water generated by a heat pump is used in a demand facility, there are two modes: one in which hot water is sequentially supplied to the demand facility, and one in which hot water is circulated to the demand facility. In the former mode, the hot water itself is consumed and waste hot water is generated. In the latter mode, only the thermal energy of the hot water is consumed and the hot water after heat utilization is returned. The information processing engine 31 of the intermediate information processing device acquires real-time environmental information corresponding to each sensor from a lower information processing device to which a temperature sensor, a flow rate sensor, etc. are connected, and generates batch environmental information. In the mode in which hot water is consumed in a demand facility, the batch environmental information includes the average supply temperature [°C], the average discharge temperature [°C], and the average hot water supply flow rate [m 3 / h], and the hot water consumption pattern at the demand facility includes the average supply temperature [℃], the average return temperature [℃], and the average circulation flow rate [m 3 / h]. The information processing engine 31 of the host information processing device generates an information aggregate by grouping these multiple types of batch environment information. The information processing engine 31 of the host information processing device calculates the heat consumption [W] using the batch environment information integrated into the information aggregate.

[0091] (4-1-3-5) Steam boiler energy management The information processing engine 31 of the intermediate information processing device acquires real-time environmental information corresponding to each sensor from a lower information processing device connected to a temperature sensor, a pressure sensor, a flow rate sensor, etc., and generates batch environmental information. The batch environmental information includes the average header air supply pressure [MPa], the average feedwater temperature [°C], the cumulative steam supply amount [m 3 ], cumulative fuel consumption [m 3], average boiler efficiency [%], and average blowdown rate [%]. The boiler efficiency and blowdown rate are calculated based on multiple types of real-time environmental information. The information processing engine 31 of the host information processing device generates an information aggregate by grouping these multiple types of batch environmental information. The information processing engine 31 of the host information processing device calculates the heat supply amount [W] and energy efficiency [%] using the batch environmental information integrated into the information aggregate. Note that the heat gain of boiler feedwater due to drain recovery and heat pump heating and the heat loss due to concentrated blowdown not only affect fuel consumption but also change the apparent boiler efficiency, so the boiler efficiency and blowdown rate are integrated into the information aggregate as related batch environmental information.

[0092] (4-1-3-6) Steam boiler demand management The information processing engine 31 of the intermediate information processing device acquires real-time environmental information corresponding to each sensor from a lower information processing device connected to a temperature sensor, a pressure sensor, a flow rate sensor, etc., and generates batch environmental information. The batch environmental information includes the average terminal supply steam pressure [MPa], the average terminal exhaust steam pressure [MPa], and the cumulative steam arrival volume [m 3 The information processing engine 31 of the host information processing device calculates the heat consumption amount [W] and the heat arrival amount [W] using the batch environment information integrated into the information aggregate. If the batch environment information related to each of the heat supply amount, heat consumption amount, and heat delivery amount is integrated prior to calculating the heat supply amount, heat consumption amount, and heat delivery amount, the heat radiation loss can be evaluated by calculating the difference between the heat supply amount and the heat delivery amount.

[0093] <4-2> Information accumulation platform The information storage platform 37 stores various numerical values, images, and other information, and also provides a fundamental environment for running software (engines, applications) and hardware. The information storage platform 37 is configured to include, for example, an operating system and a database, and centrally manages a wide variety of big data, enabling smooth processing and utilization of information. The information storage platform 37 stores environmental information and operation information that have undergone specified information processing by the information processing engine 31, as well as various types of registration information registered via input devices.

[0094] <4-3> Useful information generation engine The useful information generation engine 32 generates useful information that contributes to facility operation using the environmental information and operation information accumulated in the information accumulation platform 37. The useful information generation engine 32 has an operation performance value calculation module 321, an energy performance value calculation module 322, a quality performance value calculation module 323, an overall score value calculation module 324, a user-suggested information generation module 325, a condition monitoring information generation module 326, a reminder information generation module 327, a recommendation information generation module 328, and an alarm information generation module 329.

[0095] 6 is a diagram for explaining useful information according to an embodiment. As shown in FIG. 6, the useful information includes an operation performance value, an energy performance value, a quality performance value, a total score value, user proposal information, status monitoring information, reminder information, recommendation information, and alarm information. The operation performance value, energy performance value, and quality performance value may also be referred to as equipment availability, energy efficiency, and quality achievement rate, respectively.

[0096] (4-3-1) Operational performance calculation module The operation performance value calculation module 321 calculates an operation performance value. The operation performance value is an index value that indicates the operation performance of the industrial equipment 2. The higher the numerical value of the operation performance value, the lower the frequency of stoppages due to abnormalities, which indicates a positive impact (increased production efficiency, increased service provision efficiency) on the user's main business (production of goods, provision of services).

[0097] The operation information generated by the controller 61 includes actual operation time information linked to a normal state of the industrial equipment 2 and non-operation time information linked to an abnormal state. The operation performance value calculation module 321 calculates an operation performance value based on the actual operation time information and the non-operation time information.

[0098] The operation performance value is determined by the ratio of the actual operating time (uptime; the sum of operating time and standby time (time for output standby, start-up warm-up, etc.)) associated with the normal state of the industrial equipment 2 (machinery and equipment) to the non-operating time (downtime; the sum of abnormal shutdown time and recovery time) associated with the abnormal state during the operating hours of the factory 4. When multiple machines and equipment of the same type are installed, the operation performance value can be calculated for each machine, or for the entire group. In the latter case, if even one machine is operating, it is considered to be in operation and the operation performance value is calculated accordingly. The operation performance value is calculated based on the following formula (1). The denominator, the sum of actual operating time and non-operating time, is also called load time.

[0099] Operational performance value [%] = actual operation time / (actual operation time + non-operation time) × 100 … (1)

[0100] A specific example of a method for calculating the performance value of the entire group will be described below. The performance value calculation module 321 can calculate the performance value of the entire group by simple calculation or advanced calculation.

[0101] For example, if three boilers belong to one group and the operating performance values ​​of each boiler are as shown in the following equations (2), (3), and (4), the operating performance value of the entire group can be calculated simply by using the following equation (5).

[0102] Operational performance of No. 1 boiler: 100% …(2) No. 2 boiler operating performance: 90% …(3) Operational performance of boiler No. 3: 100% … (4) Group-wide operating performance value [%] = (100 + 90 + 100) ÷ (100 + 100 +100)×100=290÷300×100=97 …(5)

[0103] When calculating the operation performance value of the entire group using advanced calculations, the operation performance value calculation module 321 uses the accumulated operation-related data to calculate a ratio using the sum of the actual operating time and non-operating time of each machine as the denominator and the sum of the actual operating time of each machine as the numerator.

[0104] (4-3-2) Energy performance calculation module The energy performance value calculation module 322 calculates an energy performance value. The energy performance value is an index value that indicates the energy performance of the industrial equipment 2. The higher the energy performance value, the less energy is wasted, which indicates a positive impact (reduction in energy costs, reduction in carbon dioxide emissions) on the user's main business (production of goods, provision of services).

[0105] The environmental information detected by the environmental sensor 5 includes input energy information and output energy information in the industrial facility 2. The energy performance value calculation module 322 calculates an energy performance value based on the input energy information and the output energy information.

[0106] The input energy information includes the input amount of the primary utility. The output energy information includes the output amount of the secondary utility. As shown in FIG. 2 , the input amount of the primary utility is detected by an environmental sensor 5 arranged on the supply route 21. The output amount of the secondary utility is detected by an environmental sensor 5 arranged on the transportation route 22 closer to the industrial equipment 2. The energy performance value calculation module 322 calculates the energy performance value based on the input amount of the primary utility detected by the environmental sensor 5 arranged on the supply route 21 and the output amount of the secondary utility detected by the environmental sensor 5 arranged on the transportation route 22.

[0107] Energy performance values ​​are indicators that show the operational performance values ​​of industrial equipment2 (utility conversion machinery and equipment), and with some exceptions, are basically expressed as a ratio where the input amount of the primary utility is the denominator and the output amount of the secondary utility is the numerator. Energy performance values ​​include energy conversion efficiency [%], energy recovery efficiency [%], media generation efficiency [m 3 / J] and energy transfer efficiency [%] are examples.

[0108] (4-3-2-1) Energy conversion efficiency Energy conversion efficiency is an index that shows the operational performance of industrial equipment 2 used when supplying thermal energy or electrical energy to demand equipment 8. Energy conversion efficiency is expressed as a percentage, where the input energy of the primary utility is the denominator and the output energy of the secondary utility is the numerator. The higher the energy conversion efficiency, the greater the effect of suppressing running costs (fuel and electricity charges) and reducing carbon dioxide emissions.

[0109] (4-3-2-1-1) Thermal equipment When the industrial equipment 2 is a thermal device, the input energy [J] and output energy [J] are expressed by the following formulas. Input energy = fuel lower heating value x fuel consumption + electricity consumption Output energy = Outflow medium heat amount - Inflow medium heat amount The lower heating value of the fuel is a value determined by the type of fuel. The fuel consumption is measured using a flow sensor. The power consumption is measured using a power sensor.

[0110] The output energy of a steam boiler that generates steam as a secondary utility is expressed by the following formula: Output energy = (steam specific enthalpy - feedwater temperature x specific heat) x steam mass The specific enthalpy (total heat content) of saturated steam is determined by the pressure or temperature of the saturated steam and can be found by referring to a saturated steam table. The saturated steam pressure is measured using a pressure sensor. The saturated steam temperature and feedwater temperature are measured using a temperature sensor. The mass of steam generated by the steam boiler per unit time is measured using, for example, a thermal flow sensor.

[0111] The output energy of a heat transfer boiler that circulates and heats heat transfer oil as a secondary utility is expressed by the following formula. Output energy = (oil outlet temperature - oil inlet temperature) x specific heat x density x volume The oil outlet temperature and oil inlet temperature are measured using a temperature sensor. The volume of the heat transfer oil circulating through the heat transfer boiler per unit time is measured using a flow rate sensor.

[0112] The output energy of a hot water boiler that produces hot water as a secondary utility is expressed by the following formula: Output energy = (outlet water temperature - inlet water temperature) x specific heat x density x volume The outlet and inlet water temperatures are measured using temperature sensors, and the volume of water passing through the hot water boiler per unit time is measured using a flow sensor.

[0113] The output energy of a heat pump that produces hot water as a secondary utility is given by the following formula: Output energy = (outlet water temperature - inlet water temperature) x specific heat x density x volume The outlet and inlet water temperatures are measured using temperature sensors, and the volume of water passing through the heat pump per unit time is measured using a flow sensor.

[0114] The output energy of a chiller that produces chilled water as a secondary utility is expressed by the following formula: Output energy = (inlet water temperature - outlet water temperature) x specific heat x density x volume The inlet and outlet water temperatures are measured using temperature sensors, and the volume of water passing through the chiller per unit time is measured using a flow sensor.

[0115] The output energy of a heat pump chiller, which simultaneously generates hot and cold water as a secondary utility, is the same formula as a heat pump on the heating side and the same formula as a chiller on the cooling side.

[0116] The input energy required to operate industrial equipment 2 varies depending on the type of industrial equipment 2. For example, combustion boilers require fuel and electricity to operate, while heat pumps and chillers only require electricity. Power consumption includes auxiliary losses (power losses required to drive pumps, blowers, etc.). When the temperature of the inflow medium is increased through preliminary water heating, the actual output energy can be reduced, reducing fuel and power consumption and improving efficiency. In a steam boiler, if the amount of concentrated boiler water blown out increases, the amount of steam decreases accordingly, resulting in heat loss and lowering efficiency. In a heat pump, when the temperature of the heat source fluid (outside air, heat source water) increases, the amount of heat absorbed by the evaporator increases, reducing the power consumption of the refrigerant compressor and improving efficiency. In a chiller, when the temperature of the heat source fluid (outside air) decreases, the amount of heat released by the condenser increases, reducing the power consumption of the refrigerant compressor and improving efficiency.

[0117] (4-3-2-1-2) Electric air compressor When the industrial equipment 2 is an electric air compressor, the input energy [J] and output energy [J] are expressed by the following formulas. Input energy = Power consumption Output energy = discharge pressure x discharge air volume The power consumption is measured using a power sensor, the discharge pressure is measured using a pressure sensor, and the amount of discharged air per unit time is measured using a flow sensor.

[0118] The power consumption includes motor power as well as auxiliary losses (power losses required to drive cooling fans, ventilation fans, etc.).

[0119] (4-3-2-1-3) Heat recovery electric air compressor When the industrial equipment 2 is a heat recovery electric air compressor, the input energy [J] and output energy [J] are expressed by the following formula. Input energy = Power consumption Output energy = Discharge pressure x Discharge air volume + Outflow medium heat - Inflow medium heat The amount of power consumed is measured using a power sensor. The discharge pressure is measured using a pressure sensor. The amount of discharged air per unit time is measured using a flow sensor. In the output energy formula, the parts related to the discharge pressure and discharged air amount are the output energy of the compressed air, and the parts related to the outflowing medium heat quantity and the inflowing medium heat quantity are the output energy of the hot water generated by heat recovery.

[0120] The output energy (part related to the outflow medium heat quantity and the inflow medium heat quantity) of the heat recovery heat exchanger that generates hot water as a secondary utility is expressed by the following formula. Output energy = (outlet water temperature - inlet water temperature) x specific heat x density x volume The outlet and inlet water temperatures are measured using temperature sensors, and the volume of water passing through the heat recovery heat exchanger per unit time is measured using a flow rate sensor.

[0121] In electric air compressors, approximately 90% of the input energy is converted into heat of compression during the compression process, which is released into the atmosphere as waste heat. As a result, the energy conversion efficiency is very low. Therefore, by recovering the heat of compression and reusing it as hot water, a significant improvement in energy conversion efficiency (overall efficiency) can be expected.

[0122] (4-3-2-1-4) Monogenerator When the industrial facility 2 is a mono-generation generator, the input energy [J] and output energy [J] are expressed by the following formulas: Note that examples of mono-generation generators include fuel cells and gas generators. Input energy = fuel lower heating value x fuel consumption Output energy = Net output power The lower heating value of the fuel is a value determined by the type of fuel. The fuel consumption amount is measured using a flow sensor. The net output power amount is measured using a power sensor.

[0123] Once the generator is started, it operates autonomously, so the net output power is the generated power minus auxiliary losses (power losses required to drive fuel blowers, air blowers, etc.) and power conditioner losses (power losses associated with boosting and AC conversion).

[0124] (4-3-2-1-5) Cogeneration type generator When the industrial facility 2 is a cogeneration type power generator, the input energy [J] and output energy [J] are expressed by the following formulas: Note that examples of monogeneration type power generators include fuel cells and gas power generators. Input energy = fuel lower heating value x fuel consumption Output energy = Net output power + Outflow medium heat - Inflow medium heat The lower heating value of the fuel is a value determined by the type of fuel. The fuel consumption is measured using a flow sensor. The net output power is measured using a power sensor. In the output energy formula, the part related to the net output power is the output energy of electricity, and the parts related to the outflow medium heat quantity and the inflow medium heat quantity are the output energy of the hot water generated by heat recovery.

[0125] The output energy (part related to the outflow medium heat quantity and the inflow medium heat quantity) of the heat recovery heat exchanger that generates hot water as a secondary utility is expressed by the following formula. Output energy = (outlet water temperature - inlet water temperature) x specific heat x density x volume The outlet and inlet water temperatures are measured using temperature sensors, and the volume of water passing through the heat recovery heat exchanger per unit time is measured using a flow rate sensor.

[0126] In mono-generation gas generators, 50-60% of the input energy is converted into combustion heat when the gas engine is running, and this is released into the atmosphere as waste heat. In addition, in solid oxide fuel cells, 35-50% of the input energy is converted into combustion heat when the power generation module is operating, and this is released into the atmosphere as waste heat. As a result, the energy conversion efficiency is relatively low. Therefore, by recovering the combustion heat and reusing it as hot water, a significant improvement in energy conversion efficiency (overall efficiency) can be expected.

[0127] (4-3-2-2) Energy recovery efficiency Energy recovery efficiency is an index that shows the operational performance of industrial equipment 2 used to recover thermal energy that is wasted in factories 4 while supplying thermal energy to demand equipment 8. Energy recovery efficiency is expressed as a percentage, where the input energy of the primary utility is the denominator and the output energy of the secondary utility is the numerator, and is usually a value exceeding 100%. The higher the energy recovery efficiency, the greater the energy saving effect and reduction effect of carbon dioxide emissions. Energy recovery efficiency has the same meaning as the coefficient of performance (COP) in the refrigeration cycle.

[0128] (4-3-2-2-1) Thermal equipment When the industrial equipment 2 is a heat recovery type thermal equipment, the input energy [J] and output energy [J] are expressed by the following formula. Input energy = Power consumption Output energy = Outflow medium heat amount - Inflow medium heat amount Heat recovery type thermal equipment utilizes waste heat to generate secondary utilities, so the only input energy is the loss of auxiliary equipment such as water pumps and motor-operated valves. Power consumption is measured using power sensors.

[0129] The output energy of a heat recovery steam boiler that generates steam as a secondary utility is expressed by the following formula: Examples of heat recovery steam boilers include high-pressure steam boilers that use exhaust gas from gas engine generators or diesel engine generators as their heat source, and low-pressure steam boilers that use jacket waste hot water as their heat source. Output energy = (steam specific enthalpy - feedwater temperature x specific heat) x steam mass The specific enthalpy (total heat content) of saturated steam is determined by the pressure or temperature of the saturated steam and can be found by referring to a saturated steam table. The saturated steam pressure is measured using a pressure sensor. The saturated steam temperature and feedwater temperature are measured using a temperature sensor. The mass of steam generated by the steam boiler per unit time is measured using, for example, a thermal flow sensor.

[0130] The output energy of a heat recovery hot water boiler that generates hot water as a secondary utility is expressed by the following formula: An example of a heat recovery hot water boiler is a hot water boiler that uses exhaust gas from a gas engine generator or a diesel engine generator as its heat source. Output energy = (outlet water temperature - inlet water temperature) x specific heat x density x volume The outlet and inlet water temperatures are measured using temperature sensors, and the volume of water passing through the hot water boiler per unit time is measured using a flow sensor.

[0131] The output energy of a flash steam generator that generates low-pressure steam as a secondary utility is expressed by the following formula: Output energy = (steam specific enthalpy - drain temperature x specific heat) x steam mass The specific enthalpy (total heat content) of saturated steam is determined by the pressure or temperature of the saturated steam and can be found by referring to a saturated steam table. The saturated steam pressure is measured using a pressure sensor. The saturated steam temperature and drain temperature are measured using a temperature sensor. The mass of steam generated by the flash steam generator per unit time is measured using a thermal flow sensor.

[0132] In a configuration where a flash steam generator is combined with a steam compressor to boost the pressure of the low-pressure steam generated by the flash steam generator, the motor power of the steam compressor is added to the input energy. Also, in the steam compressor, cooling water is sprayed onto the screw rotor, and this cooling water evaporates due to the heat of compression and friction, so the total steam mass increases and the output energy also increases.

[0133] (4-3-2-2-2) Steam-driven air compressor If the industrial equipment 2 is a heat recovery steam-driven air compressor, the input energy [J] and output energy [J] are expressed by the following formula: Input energy = Power consumption Output energy = Discharge pressure x Discharge air volume + Outflow medium heat - Inflow medium heat The amount of power consumed is measured using a power sensor. The discharge pressure is measured using a pressure sensor. The amount of discharged air per unit time is measured using a flow sensor. In the output energy formula, the parts related to the discharge pressure and discharged air amount are the output energy of the compressed air, and the parts related to the outflowing medium heat quantity and the inflowing medium heat quantity are the output energy of the hot water generated by heat recovery.

[0134] The output energy (part related to the outflow medium heat quantity and the inflow medium heat quantity) of the heat recovery heat exchanger that generates hot water as a secondary utility is expressed by the following formula. Output energy = (outlet water temperature - inlet water temperature) x specific heat x density x volume The outlet and inlet water temperatures are measured using temperature sensors, and the volume of water passing through the heat recovery heat exchanger per unit time is measured using a flow rate sensor.

[0135] Steam-driven air compressors use steam, a secondary utility generated in a steam boiler, to rotate a steam motor, which is the prime mover, to drive the compressor itself.As a result, the only input energy is auxiliary losses (power losses required to drive cooling fans, ventilation fans, etc.).

[0136] (4-3-2-3) Media generation efficiency The media generation efficiency is an index that shows the operational performance of industrial equipment 2, which is mainly used when consuming compressed air or treated water in demand equipment 8. The media generation efficiency is expressed as the ratio of the input energy of the primary utility as the denominator to the output media amount of the secondary utility as the numerator, and is expressed in units of [m 3 The higher the medium generation efficiency, the greater the effect of reducing running costs (electricity charges) and carbon dioxide emissions.

[0137] (4-3-2-3-1) Electric air compressor If industrial equipment 2 is an electric air compressor, the input energy [J] and the output medium volume [m 3 ] is expressed by the following formula: Input energy = Power consumption Output medium volume = Discharge air volume The power consumption is measured using a power sensor, and the amount of air discharged per unit time is measured using a flow sensor.

[0138] The power consumption includes auxiliary losses (power losses required to drive cooling fans, ventilation fans, etc.). The medium generation efficiency indicates the medium generation capacity per unit of energy, and is expressed as the specific energy [kW / (m 3 / min)] with the numerator and denominator reversed. Note that as the outside air temperature rises, the density of the air decreases, so more energy is required for compression. Therefore, the generation efficiency may be corrected for temperature (e.g., converted to 25°C).

[0139] In the case of a steam-driven air compressor, the compressor itself is driven by a steam motor, and steam is a secondary utility, so the input energy is only the amount of auxiliary losses, and the generation efficiency exceeds that of an electric type.

[0140] (4-3-2-3-2) Water treatment equipment If industrial equipment 2 is an RO membrane device, which is a type of water treatment equipment, the input energy [J] and the output medium amount [m 3 ] is expressed by the following formula: Input energy = Power consumption ·Output medium amount = permeated water amount The amount of power consumption is measured using a power sensor, and the amount of permeated water per unit time is measured using a flow sensor.

[0141] The power consumption includes the power required to drive the water supply pump, pressure pump, etc. Note that as the raw water temperature decreases, the viscosity of the water decreases, requiring more energy to transport the water. Therefore, the medium generation efficiency may be temperature-corrected (e.g., converted to 25°C).

[0142] (4-3-2-4) Energy transport efficiency Energy transport efficiency is an index that indicates the degree to which thermal energy loss is avoided in the transport process of secondary utilities, and affects, for example, the energy performance value of the entire equipment group. Energy transport efficiency is the delivery ratio (= delivered amount / transmitted amount) of the amount of thermal energy of secondary utilities (steam heat, hot water heat, etc.) sent from industrial equipment 2 to demand equipment 8, expressed as a percentage. Since the ideal energy transport efficiency, where there is no energy loss in the transport process, is 100%, the energy loss rate is calculated by subtracting the actual energy transport efficiency from this 100%. The amount of thermal energy transmitted and the amount of thermal energy delivered are detected using measurements from temperature sensors and flow rate sensors.

[0143] If the insulation in the steam or hot water transport path 22 (including tanks, etc.) deteriorates or peels off, heat loss occurs due to heat radiation, reducing energy transport efficiency. If a steam trap in the steam transport path 22 fails, causing condensate to accumulate or steam to leak externally, heat loss occurs due to a drop in steam temperature or partial release, reducing energy transport efficiency. If the piping sealant in the compressed air transport path 22 deteriorates or the piping body is damaged, leakage loss occurs due to external leakage, reducing energy transport efficiency. Therefore, by managing energy transport efficiency, it becomes possible to determine the need for repairs to the transport path 22.

[0144] (4-3-2-5) Energy performance of the entire group A specific example of a method for calculating the energy performance value of the entire group will be described below: The energy performance value calculation module 322 can calculate the energy performance value of the entire group by simple calculation or advanced calculation.

[0145] For example, if three boilers belong to one group and the energy performance values ​​of each boiler are as shown in the following equations (6), (7), and (8), the energy performance value of the entire group can be calculated simply by using the following equation (9).

[0146] Energy performance of boiler No. 1: 95% …(6) Energy performance of boiler No. 2: 95% …(7) Energy performance of boiler No. 3: 92% …(8) Energy performance score of the entire group [%] = (95 + 95 + 92) ÷ (100 + 100 +100)×100=282÷300×100=94 …(9)

[0147] When calculating the energy performance value of the entire group using advanced calculations, the energy performance value calculation module 322 uses the accumulated energy-related data to calculate a ratio using the total input energy value of each unit as the denominator and the total output energy value of each unit as the numerator.

[0148] (4-3-3) Quality performance value calculation module The quality performance value calculation module 323 calculates a quality performance value. The quality performance value is an index value that indicates the quality performance of the industrial equipment 2. The higher the quality performance value, the better the quality, which indicates a positive impact on the user's main business (production of goods, provision of services) (continuity of business activities through the production of high-quality products, objects to be sterilized, and objects to be cleaned).

[0149] The environmental information detected by the environmental sensor 5 includes actual quality level information of the medium or article produced in the industrial facility 2. The quality performance value calculation module 323 calculates a quality performance value based on the actual quality level information and the user's required quality level information.

[0150] The media produced by industrial facility 2 are expected to include secondary utilities such as steam, hot water, cold water, compressed air, electricity, heating oil, and treated water. All media except treated water are energy media. Treated water can also be used as a cleaning medium, rinsing medium, and other process media in addition to being an energy medium. Actual quality level information (environmental information) for media includes pressure, temperature, water quality, and voltage.

[0151] The items that are expected to be produced in the industrial facility 2 include processed items to be washed and sterilized, washed items to be washed, cooked food, prepared beverages, etc. Information on the actual quality level of the items will be acquired as environmental information by constructing a system that automatically reads the color tone and scale of a judging tool such as an indicator using an image sensor (camera) and converts it into a numerical value.

[0152] (4-3-3-1) Steam (4-3-3-1-1) Steam supply pressure The specific enthalpy (total heat content) of saturated steam is determined by the pressure of the saturated steam. To generate steam with the heat content (temperature) required by the demand facility, the supply pressure of the steam boiler must meet the required pressure. During the specified operating period of the steam boiler, the boiler operating time when the supply pressure is greater than or equal to the required pressure is defined as A, and the boiler operating time when the supply pressure is less than the required pressure is defined as B. The quality performance value [%] of the supply pressure is calculated as A / (A+B) x 100.

[0153] (4-3-3-1-2) Steam dryness Dryness fraction is the weight ratio of the gas phase to the liquid phase in steam, and affects the total heat content of steam. In other words, steam with a dryness fraction of 100% (wetness fraction of 0%) has only the latent heat of saturated steam at that pressure, and steam with a dryness fraction of 0% (wetness fraction of 100%) has only the sensible heat of saturated water at that pressure. As the dryness fraction decreases, the proportion of latent heat decreases, and the total heat content decreases. Dryness fraction can be measured using a throttling calorimeter or absorbance analyzer, and it can usually be thought of as "dryness fraction [%] = quality performance value [%]."

[0154] (4-3-3-1-3) Steam purity When live steam comes into direct contact with products during production processes such as cooking, sterilization, and drying, steam containing impurities is unacceptable. Steam that is free from water treatment chemicals and concentrated boiler water is of the highest quality. Steam purity is determined by cooling wet or dry steam to condense it and measuring its electrical conductivity and pH. Distilled water has an electrical conductivity of 10 μS / cm or less (at 25°C) and a pH of around 7 (when no carbon dioxide is dissolved in the air). These values ​​are used as the standard for determining the quality performance value. For example, for electrical conductivity, the quality performance value [%] can be calculated as [1 - (actual EC - reference EC) / actual EC] x 100. If the actual EC of steam condensate is 20 μS / cm, the quality performance value is 50%, and if the actual EC of steam condensate is 10 μS / cm, the quality performance value is 100%. Note that if the actual EC is less than 10 μS / cm, the quality performance value can be set to 100%.

[0155] (4-3-3-2) Hot or cold water supply temperature The same concept can be applied as for steam boilers, and within the specified operating period of a heat pump, the heat pump operating time when the supply temperature is greater than or equal to the required temperature is defined as A, and the heat pump operating time when the supply temperature is less than or equal to the required temperature is defined as B, and the quality performance value [%] of the supply temperature is calculated as A / (A+B) x 100.In the case of a chiller, the chiller operating time when the supply temperature is less than or equal to the required temperature is defined as A, and the chiller operating time when the supply temperature is greater than the required temperature is defined as B, and the quality performance value [%] of the supply temperature is calculated as A / (A+B) x 100.

[0156] (4-3-3-3) Compressed air supply pressure The same concept as for steam boilers can be applied. During the specified operating period of the air compressor, the operating time of the air compressor when the supply pressure is greater than or equal to the required pressure is defined as A, and the operating time of the air compressor when the supply pressure is less than the required pressure is defined as B. The quality performance value [%] of the supply pressure is calculated as A / (A+B) x 100.

[0157] (4-3-3-4) Quality of treated water Typically, the electrical conductivity of RO water is 5 μS / cm (25°C) or less, so quality performance values ​​are calculated based on this value. For example, the quality performance value [%] is calculated as [1 - (actual EC - standard EC) / actual EC] x 100. Furthermore, quality performance values ​​are controlled by the turbidity of the treated water for filtration processes (membrane filtration, sand filtration), and the residual chlorine concentration of the treated water for activated carbon treatment.

[0158] (4-3-3-5) Electricity supply voltage The quality of the electricity (AC) generated by a generator is evaluated by voltage and frequency. During the specified operating period of a generator such as a fuel cell, the operating time of the generator when the supply voltage is within a specified range above and below the required voltage is defined as A, and the operating time of the generator when the supply voltage is not within the specified range above and below the required voltage is defined as B. The quality performance value [%] of the supply voltage is calculated as A / (A+B) x 100.

[0159] (4-3-3-6) Sterilization and cleaning level of items to be sterilized and cleaned In the central supply room of a medical institution, a sterilization indicator is used as a tool to evaluate whether a sterilizer, which is a medical device, is operating normally and the items to be sterilized have been completely processed. Also, a cleaning indicator is used as a tool to evaluate whether a washer is operating normally and the items to be cleaned have been completely processed. For a sterilizer or washer, a quality performance value is calculated based on the judgment level of the sterilization indicator or cleaning indicator (for example, a pass / fail judgment based on the gradual degree of color change). Quality performance score [%] = Number of passes / (Number of passes + Number of failures) x 100

[0160] (4-3-3-7) Group-wide quality performance score A specific example of a method for calculating the quality performance value of the entire group will be described below: The quality performance value calculation module 323 can calculate the quality performance value of the entire group by simple calculation or advanced calculation.

[0161] For example, if three boilers belong to one group and the quality performance values ​​of each boiler are the values ​​shown in the following equations (10), (11), and (12), the quality performance value of the entire group can be calculated simply by the following equation (13): The quality performance value of a boiler indicates the quality performance value of the steam supply pressure.

[0162] Quality performance of boiler No. 1: 95% …(10) Quality performance of No. 2 boiler: 100% …(11) Quality performance of boiler No. 3: 100% … (12) Overall group quality score [%] = (95 + 100 + 100) ÷ (100 + 100 +100)×100=295÷300×100=98 …(13)

[0163] When calculating the quality performance value for the entire group using advanced calculations, the quality performance value calculation module 323 uses the accumulated historical data of steam supply pressure (time progression of pressure changes) to calculate a ratio using the sum of the operating times A+B of each unit as the denominator and the sum of the operating times A of each unit as the numerator.

[0164] (4-3-4) Total score calculation module The overall score calculation module 324 calculates an overall score by combining two or more performance values ​​from the operation performance value, the energy performance value, and the quality performance value. The overall score is an index value that indicates the overall performance of the industrial equipment 2. The higher the overall score value, the higher the quality of the service provided by the maintenance company, which indicates that it has a positive impact on the user's business activities (creating an environment where the user can concentrate on their core business).

[0165] For example, the percentages of the operation performance value, energy performance value, and quality performance value can each be converted into a score out of 100, and the three performance values ​​can be added together to arrive at a total score of up to 300. If the user places more importance on a particular performance value, they can adjust the scale (e.g., 100 x 1.5). For example, even if the energy performance value is not good, if the operation performance value and quality performance value are high enough, the production process can continue, so these two performance values ​​can be weighted more heavily.

[0166] A specific example of a method for calculating the total score will be described below. The total score calculation module 324 can calculate the total score using an additive formula or a multiplicative formula. As an example, if the operation performance value is 97, the energy performance value is 94, and the quality performance value is 98, the total score S1 calculated using the additive formula is expressed by the following formula (14), and the total score S2 calculated using the multiplicative formula is expressed by the following formula (15). Note that the maximum score for the total score S1 is 300, and the maximum score for the total score S2 is 1000.

[0167] S1=97+94+98=289 …(14) S2=97×94×98÷1000=894…(15)

[0168] (4-3-5) User-suggested information generation module The user-suggested information generation module 325 generates user-suggested information related to value-added services that provide user benefits, based on each performance value and knowledge information, and is used to propose the service to the user. Knowledge information refers to information that contributes to maintaining or improving each of the above-mentioned performance values, i.e., the operation performance value, the energy performance value, and the quality performance value. The knowledge information is stored in the database 38. The user-suggested information generation module 325 generates user-suggested information based on each performance value and knowledge information stored in the database 38.

[0169] 7 is a diagram illustrating user proposal information according to an embodiment. As shown in FIG. 7, the following are exemplified as user proposal information that improves the energy performance value, that is, provides energy saving benefits. (1) If a downward trend in the energy conversion efficiency of the steam equipment is observed, a change in the steam boiler output condition value is proposed. (2) If a downward trend in the energy conversion efficiency of cooling and heating equipment is observed, we will propose changes to the output condition values ​​of heat pumps and chillers. (3) If a downward trend in the energy conversion efficiency of the air equipment is observed, we propose changing the output condition values ​​of the air compressor. (4) If a downward trend in the energy transport efficiency of steam equipment is observed, we propose steam trap diagnosis of the steam piping network. (5) If a downward trend in the energy transport efficiency of cooling and heating equipment is observed, we propose equipment renovation based on heat dissipation measurements. (6) If a downward trend in the energy transport efficiency of air equipment is observed, we propose air leak diagnosis of the compressed air transport piping network.

[0170] (4-3-6) Status monitoring information generation module The status monitoring information generation module 326 generates status monitoring information by overlaying a mark that visually represents the condition of each constituent unit of the industrial equipment 2 on an equipment flow diagram read from the database 38. The operation information generated by the controller 61 includes the condition of the industrial equipment 2. The database 38 stores an equipment flow diagram that depicts the overall configuration or partial configuration of the industrial equipment 2. The status monitoring information generation module 326 generates status monitoring information based on the condition generated by the controller 61 and the equipment flow diagram stored in the database 38.

[0171] Semi-real-time information on the condition of the industrial equipment 2 is displayed graphically on a portal page displayed on the user terminal 40 (provision of visualization content). For example, OK / NG marks are superimposed on the constituent units of an equipment flow diagram. Constituent units of machinery and equipment may be represented not only by image diagrams but also by photographs.

[0172] (4-3-7) Reminder information generation module The reminder information generation module 327 generates reminder information that notifies the scheduled maintenance timing. The maintenance timing is planned by the maintenance planning engine 35, which will be described later.

[0173] The reminder information may include the time of the before-maintenance visit (visit date and time) as well as the name, photo, and name of the service technician in charge. The service technician in charge is a worker who can be dispatched by the maintenance company in charge of the maintenance work and the maintenance business partner who complements the maintenance work. The time of condition-based maintenance is set mainly by judging signs of abnormality from changes in environmental information. The time of time-based maintenance is set mainly based on operation information (for example, when the accumulated operating time since the previous inspection reaches a specified time).

[0174] (4-3-8) Recommendation information generation module The recommendation information generation module 328 generates recommendation information notifying the content of measures recommended for maintaining the capacity or avoiding faults of the industrial equipment 2. The database 38 stores the content of measures recommended for maintaining the capacity or avoiding faults of the industrial equipment 2. The action content extraction engine 36 extracts the content of measures associated with the feature amount from the database 38 when the feature amount included in the environmental information or operation information accumulated in the information accumulation platform 37 is a predetermined numerical value. The recommendation information generation module 328 generates recommendation information notifying the content of measures extracted by the action content extraction engine 36, which will be described later.

[0175] FIG. 8 is a diagram for explaining recommendation information according to an embodiment. The recommendation information generation module 328 displays the details of daily management-level actions that the user can take (mainly the replenishment and replacement of consumables). For example, this includes the replenishment of water treatment chemicals and reagents for water quality sensors, the replenishment of chemicals for regenerating water treatment materials (granulated salt for regenerating cation exchange resin in water softeners), and the replacement of filters (air filters, water filters). The decision to issue recommendation information (notification decision) is made based on operation information or environmental information. As shown in FIG. 8, the following are examples of feature amounts and recommendation information:

[0176] (1) If the chemical level (environmental information) in the water treatment chemical tank falls below the level threshold, it is recommended to replenish the water treatment chemical. (2) If the number of times the chemical solution has been dispensed (operation information) since the last time the reagent cartridge for the water quality sensor was replaced exceeds the threshold value for the number of times the chemical solution has been dispensed, it is recommended that the water quality sensor reagent be replenished. (3) If the number of times the regeneration chemical has been regenerated since the last replenishment (operation information) exceeds the regeneration count threshold, or if the chemical solution concentration at the time of regeneration (environmental information) exceeds the concentration threshold, it is recommended that the regeneration chemical be replenished. (4) If the cumulative operating time of the air compressor since the last air filter replacement (operation information) exceeds the time threshold or if the pressure loss (environmental information) exceeds the loss threshold, it is recommended to replace the air filter. (5) If the cumulative water flow rate or cumulative water flow time (operating information) since the last water filter replacement exceeds the water flow threshold, or if the pressure loss (environmental information) exceeds the loss threshold, it is recommended to replace the water filter.

[0177] (4-3-9) Alarm information generation module The alarm information generation module 329 generates alarm information indicating the occurrence status of a malfunction event based on the abnormality notification signal transmitted by the controller 61. The operation information generated by the controller 61 includes the abnormality notification signal transmitted by the controller 61 when a malfunction event occurs in the industrial equipment 2. The alarm information generation module 329 generates alarm information indicating the occurrence status of a malfunction event based on the abnormality notification signal transmitted by the controller 61.

[0178] The alarm information generation module 329 displays the occurrence status of a malfunction event based on an abnormality notification signal (such as an alarm code or an abnormality occurrence flag included in the communication message) sent by the machine / tool ​​controller 61. The communication message may be binary data or text data (such as email). In the case of a serious alarm that necessitates the shutdown of the machine / tool, recovery work is the job of a service technician, so the alarm information may include, for example, the expected date and time of the service technician's arrival. In the case of a minor alarm that can be handled by the user, a button for obtaining content that describes the procedure for resolving the alarm is displayed. Content that can be called up using the content obtainment button includes manuals (document-based, video-based), instruction manuals, etc.

[0179] <4-4> UI providing engine The UI providing engine 33 provides a user interface (UI) for displaying the useful information generated by the useful information generating engine 32 on the user terminal 40.

[0180] The user interface is a means of communication that allows users to connect with maintenance companies via ICT, and includes a user portal. The user portal includes a portal screen (UI screen) that is displayed on the user terminal 40. The portal screen includes multiple portlets. A portlet is a detachable user interface component that is placed on the portal screen.

[0181] The UI providing engine 33 provides a user portal (UI screen) as a user interface. The user portal includes a portal page with a screen configuration corresponding to the logged-in user and portlets that are incorporated into the portal page and operate to display useful information on the screen. By accessing the portal site created and distributed by the UI providing engine 33 from the user terminal 40, the user can view and obtain various useful information displayed on the portal page.

[0182] The type and level of useful information provided by the user portal is determined by the contents of the service contract concluded with the user. When a user accesses the portal site, a portal page with a screen configuration appropriate for the logged-in user is generated. The portal page is provided with multiple layout forms that can be customized according to, for example, the type of industry.

[0183] The UI providing engine 33 includes a portal page generating module 331 , a first tab group generating module 332 , a second tab group generating module 333 , and a portlet generating module 334 .

[0184] The portal page generation module 331 generates a portal page with a screen configuration corresponding to the logged-in user.

[0185] The first tab group generation module 332 generates a first tab group in a predetermined area of ​​the portal page for the user to select an administration menu from among a plurality of administration menus, the administration menu from which the user wishes to receive information.

[0186] The second tab group generation module 333 generates a second tab group in a predetermined area of ​​the portal page for the user to select a facility group from which the user wishes to receive information from among a plurality of facility groups.

[0187] The portlet generation module 334 generates a portlet that displays useful information in a predetermined area of ​​the portal page when a predetermined management menu is selected from the first tab group and a predetermined equipment group is selected from the second tab group. The portlet generation module 334 is prepared according to the number of useful information to be provided (information related to operation performance values, energy performance values, quality performance values ​​and overall score values, equipment flow information, condition information, customer proposal information, reminder information, recommendation information, alarm information).

[0188] <4-5>Performance prediction engine The performance value prediction engine 34 inputs the environmental information and operation information accumulated in the information accumulation platform 37 into a mathematical model that simulates the operation of the industrial equipment 2, and outputs one or more virtual performance values ​​from the mathematical model, including the operation performance value, energy performance value, and quality performance value.

[0189] 9 is a diagram for explaining the processing of the performance value prediction engine 34 according to the embodiment. The performance value prediction engine 34 calculates virtual performance values, which are virtual performance values, using digital twin technology. The mathematical model is industrial equipment 2 in a virtual space that simulates the operation of the industrial equipment 2. The performance value prediction engine 34 inputs environmental information detected by the environmental sensors 5 and operation information generated by the controller 61 into the mathematical model, and causes the mathematical model to output one or more virtual performance values ​​from among the operation performance value, energy performance value, and quality performance value.

[0190] The user-suggested information generation module 325 can generate user-suggested information based on the output virtual performance value and knowledge information from the mathematical model.

[0191] <4-6> Maintenance planning engine The maintenance planning engine 35 plans the timing of condition-based maintenance or time-based maintenance for the industrial equipment 2 based on the environmental information and operation information accumulated in the information accumulation platform 37. Maintenance includes before maintenance and after maintenance. Before maintenance refers to maintenance performed before an abnormality occurs in the industrial equipment 2. After maintenance refers to maintenance performed after an abnormality occurs in the industrial equipment 2. Before maintenance includes condition-based maintenance (CBM) and time-based maintenance (TBM). Condition-based maintenance is the most preferable maintenance method because it reduces unnecessary work more than time-based maintenance.

[0192] <4-7> Treatment content extraction engine When a feature contained in the environmental information or operation information stored in the information storage platform 37 is a predetermined numerical value, the treatment content extraction engine 36 extracts the treatment content (see FIG. 8) associated with the feature from the database 38.

[0193] <4-8>Database The database 38 accumulates knowledge information that contributes to maintaining or improving each of the performance values ​​of operation, energy, and quality. The database 38 stores an equipment flow diagram depicting the overall configuration or partial configuration of the industrial equipment 2. The database 38 determines recommended actions to maintain the capacity of the industrial equipment 2 or to avoid failures. The database 38 may be prepared according to the number of modules that use the registered information.
