Problems to be Solved by the Invention

[0005] In order to promote the reduction of carbon dioxide emissions and the efficiency improvement of the manufacturing process, it is important to accurately grasp and analyze the operation status of manufacturing equipment as a previous step. Also, in order to promote the efficiency improvement of the manufacturing process, it is important to grasp and analyze not only manufacturing equipment but also the operation status of workers and operations.

[0006] An object of the present invention is to enable efficient grasping of the operation status of at least one of equipment, workers, and operations. [Means for solving the problem]

[0007] This application includes several means to solve at least some of the above problems, and some examples are as follows.

[0008] One aspect of the present invention is an operational analysis device comprising: an acquisition unit that acquires current values ​​or power values ​​for each of one or more pieces of equipment from sensors provided on each of the pieces of equipment; an analysis unit that determines, based on the acquired current values ​​or power values, whether the piece of equipment is stopped, idle, or in operation, and stores the operational state in a storage unit in association with an identifier for the piece of equipment; and a user interface control unit that outputs to the user an analysis result, including at least the operational state of each of the pieces of equipment, generated by the analysis unit.

[0009] The analysis unit may generate one or more of the following as analysis results for each of the aforementioned pieces of equipment. • Cumulative time during stoppage and idle periods (at least one of these periods) • Total time spent in combinations of stopped and idle states • Percentage of cumulative operating time between at least one of the stopped and idle periods. • Combination of stopped and idle states and the percentage of total operating time

[0010] The analysis unit may use the acquired current value or power value for each of the equipment to generate at least one of the electricity charges and CO2 emissions as the analysis results.

[0011] The acquisition unit may acquire detection data from beacon receivers installed on each of the pieces of equipment, relating to beacon transmitters installed on each of the one or more workers, which are detected by each beacon receiver. The analysis unit may, for each piece of equipment, determine the workers who will perform work using the equipment based on the acquired detection data, and store the worker identifiers in the storage unit, associating them with the equipment identifiers.

[0012] If the analysis unit is in a state where no detection data has been acquired for a certain period of time with respect to the equipment, it may determine the start time of the work performed by the worker based on the time indicated by the first detection data acquired. If no detection data has been acquired for a certain period of time with respect to the equipment, it may determine the end time of the work performed by the worker based on the time indicated by the last detection data acquired.

If the equipment is stopped or idle, the analysis unit may determine that the worker performing the work using the equipment is preparing, and store the worker's operating status in the storage unit in association with the worker's identifier. The analysis unit may then generate the worker's operating status as the analysis result for each worker.

[0015] The acquisition unit may acquire detection data from beacon receivers attached to each of the pieces of equipment, relating to beacon transmitters provided on each of the items used in one or more tasks, which have been detected by each beacon receiver. The analysis unit may determine, based on the acquired detection data, the tasks to be performed using each piece of equipment, and store the task identifier in the storage unit, associating it with the equipment identifier.

[0016] The analysis unit may, if no detection data has been acquired for the equipment for a certain period of time or longer, determine the start time of the operation based on the time indicated by the next acquired detection data, and if no detection data has been acquired for the equipment for a certain period of time or longer, determine the end time of the operation based on the time indicated by the last acquired detection data.

[0017] The analysis unit may generate one or more of the following as analysis results for each of the above operations. • The start time and end time of the work in each of the above-mentioned facilities. • Cumulative time for the operations at each of the above-mentioned facilities Operational analysis device.

[0018] The analysis unit may determine that the operational status of the work performed using the equipment is "work in progress" when the equipment is operating, and store the operational status of the work in the storage unit in association with the work identifier. If the equipment is stopped or idle, the analysis unit may determine that the operational status of the work performed using the equipment is "preparation in progress," and store the operational status of the work in the storage unit in association with the work identifier. The analysis unit may generate the operational status of each work as the analysis result.

[0019] Another aspect of the present invention is an operation analysis system comprising sensors provided on one or more pieces of equipment, an operation analysis device, and a terminal device, wherein the operation analysis device includes: an acquisition unit that acquires current values ​​or power values ​​for each piece of equipment from each of the sensors; an analysis unit that determines, based on the acquired current values ​​or power values, whether the piece of equipment is stopped, idle, or in operation, and stores the operation state in a storage unit in association with an identifier for the piece of equipment; and a user interface control unit that outputs analysis results, including at least the operation state of each piece of equipment, generated by the analysis unit, to the terminal device.

[0020] Still another aspect of the present invention is an operation analysis method executed by an operation analysis device, the method including: an acquisition step of acquiring a current value or a power value related to each of one or more facilities from sensors provided for each of the facilities; an analysis step of determining, for each of the facilities, in which of the operating states of stopped, idle, and operating based on the acquired current value or power value, and storing the operating state in a storage unit in association with an identifier of the facility; and an output step of outputting to a user an analysis result including at least the operating state of each of the facilities generated by the analysis step.

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In all drawings used to describe an embodiment, the same reference numerals will be used for identical components, and repeated descriptions will be omitted. Furthermore, in the following embodiment, it goes without saying that the components (including element steps, etc.) are not necessarily essential unless specifically stated or considered to be clearly essential in principle. Also, when we say "consisting of A," "made of A," "having A," or "containing A," it goes without saying that other elements are not excluded unless specifically stated that only that element is included. Similarly, in the following embodiment, when referring to the shape, positional relationship, etc. of components, etc., it will include those that are substantially similar or approximate to their shape, etc., unless specifically stated or considered to be not in principle.

[0026] Figure 1 shows an example of the system configuration of the operational analysis system according to this embodiment.

[0027] The operational analysis system collects current values ​​using current sensors 4 installed on the equipment 3 to be analyzed (for example, machines or devices used in product processing) and analyzes the operating status (operational state) of the equipment 3.

[0028] Furthermore, the operational analysis system uses a beacon receiver 5 installed on the equipment 3 and a beacon transmitter 7 installed on the worker 6 being analyzed (for example, a worker who operates the equipment and performs product processing work) to detect when the worker 6 approaches or leaves the equipment 3 and analyzes the operational status of the worker 6.

[0029] Furthermore, the operational analysis system uses a beacon receiver 5 installed on the equipment 3 and a beacon transmitter 9 installed on the item 8 used in the work to be analyzed (for example, work instructions and tools used in product processing work, and accessories such as binders to which these are fixed) to detect when the item 8 approaches or leaves the equipment 3, and analyzes the operational status of the work in which the item 8 is used.

[0030] Needless to say, multiple pieces of equipment 3, multiple workers 6, and multiple items 8 may be included in the analysis. Current sensors 4 and beacon receivers 5 are provided corresponding to each piece of equipment 3, beacon transmitters 7 are provided corresponding to each worker 6, and beacon transmitters 9 are provided corresponding to each item 8.

[0031] Of course, the operational analysis system is not limited to performing all three operational analyses related to equipment, workers, and work; it may perform one or two of them.

[0032] The following explanation is easier to understand if you imagine a scenario where an operational analysis system performs three operational analyses related to the manufacturing of a certain product: processing equipment, processing workers, and processing operations.

[0033] The operation analysis system comprises an operation analysis device 1, a current sensor 4, a beacon receiver 5, a beacon transmitter 7, and a beacon transmitter 9. The operation analysis device 1 and the current sensor 4 are connected via a network N such as the Internet or a LAN (Local Area Network). The operation analysis device 1 and the current sensor 4 may also be connected via a gateway G. The operation analysis device 1 and the beacon receiver 5 are connected via a network N. The operation analysis device 1 and the beacon receiver 5 may also be connected via a gateway G. The gateway G aggregates and converts the output data from the current sensor 4 and the beacon receiver 5 as needed and transmits it to the operation analysis device 1. The data may be further transferred from the gateway G to the operation analysis device 1 via a data transfer service.

[0034] The current sensor 4 is an ammeter installed at a measurement point such as the power cable of the equipment 3, and measures and outputs the current value at the measurement point. Preferably, the current sensor 4 is an ammeter that can be attached and detached simply by clamping it to the measurement point such as the power cable. This allows for easy installation without modifying the equipment 3.

[0035] The current sensor 4 outputs the current value measured at a set timing as measurement data, associating it with the measurement time and sensor identifier. The measurement timing can be, for example, a periodic timing or a specified time. Needless to say, "time" is not limited to hours, minutes, and seconds, but may also include the year, month, and day (as is the case in this specification).

[0036] The beacon receiver 5 is installed in the facility 3 (for example, on the casing of the facility 3 or at any location within the area where the facility 3 is installed). The beacon receiver 5 detects the approach of both the beacon transmitter 7 and the beacon transmitter 9 and outputs detection data. The detection data includes, for example, the identifier of the beacon receiver 5 (receiver identifier), the detection time, and the identifier of the detected beacon transmitter (transmitter identifier). The detection data may also include the radio wave intensity of the detected beacon signal.

[0037] The beacon transmitter 7 is installed on the worker 6 (for example, it may be attached to the worker 6's body or clothing, or the worker 6 may carry it). The beacon transmitter 7 transmits a beacon signal containing a transmitter identifier at a set timing, for example. The transmission timing can be, for example, periodic.

[0038] The beacon transmitter 9 is installed on the article 8 (for example, attached to the article 8 with fixing means such as double-sided tape or clips). The beacon transmitter 9 transmits a beacon signal including a transmitter identifier at a set timing, for example. The transmission timing can be, for example, periodic.

[0039] The operational analysis system may include a terminal device T for use by the user. The operational analysis system 1 and the terminal device T are connected via a network N so as to be able to communicate. The terminal device T is, for example, a computer such as a PC (Personal Computer), a tablet terminal, or a smartphone. The terminal device T is equipped with input devices such as a keyboard or touch panel, and display devices such as an LCD display. The user is, for example, a business operator that provides operational analysis services or a business operator that manages the objects of analysis, such as equipment 3.

[0040] The operational analysis device 1 is a device that collects output data from the current sensor 4 and the beacon receiver 5 and performs operational analysis. The operational analysis device 1 is a computer such as a server or PC, and is operated by, for example, a business that provides operational analysis services or a business that manages the equipment to be analyzed, such as the facility 3. The operational analysis device 1 comprises a processing unit 11, a storage unit 15, and a communication unit 18. The operational analysis device 1 may be configured by the cooperation of multiple computers, and is not limited to physical machines but may also be a virtual machine.

[0041] The processing unit 11 controls the entire operational analysis device 1. The storage unit 15 stores information and data used by the processing unit 11. The communication unit 18 is an interface for connecting the operational analysis device 1 to the network N. The processing unit 11 includes, functionally, a UI (User Interface) control unit 12, an acquisition unit 13, and an analysis unit 14. The storage unit 15 stores collected data 16 and analysis data 17.

[0042] The UI control unit 12 receives information entered by the user into the terminal device T via the communication unit 18, and displays the information on the terminal device T. The terminal device T is equipped with, for example, a web browser, and via the web browser, receives and displays an operation screen such as a web page sent from the UI control unit 12, accepts information input into the operation screen, and transmits it to the UI control unit 12. Alternatively, the terminal device T is equipped with, for example, an application program dedicated to operational analysis, and via the application, displays an operation screen pre-configured by the application, accepts information input into the operation screen, and sends it to the UI control unit 12.

[0043] The acquisition unit 13 acquires output data from the current sensor 4 and the beacon receiver 5 via the communication unit 18. As described above, the measurement data from the current sensor 4 includes, for example, the current value, measurement time, sensor identifier, etc. The detection data from the beacon receiver 5 includes, for example, the receiver identifier, detection time, transmitter identifier, etc. The acquisition unit 13 may store the acquired output data in the storage unit 15.

[0044] The operational analysis system may use a power sensor instead of or in addition to the current sensor 4. The power sensor is preferably a power meter that can be attached and detached simply by clamping it to a measurement point such as a power cable. This allows for easy installation without modifying the equipment 3. The power sensor outputs measurement data, such as the power value (power W or energy amount (cumulative power)) measured at a set timing, associated with the measurement time and sensor identifier. The acquisition unit 13 acquires the output data from the power sensor via the communication unit 18. Of course, if the power sensor can measure current values, the current value may be acquired and used in the same way as with the current sensor 4. Equipment 3 with the current sensor 4 and equipment 3 with the power sensor may be mixed together.

[0045] The analysis unit 14 generates collected data 16 based on the output data acquired by the acquisition unit 13 and stores it in the storage unit 15. This will be explained in detail below with reference to Figure 2.

[0046] Figure 2 shows an example of the data structure of the collected data according to this embodiment. The collected data 161 related to the equipment is generated based on measurement data from the current sensor 4 and includes time, sensor identifier, current value, equipment identifier, and status. The time, sensor identifier, and current value are the measurement time, sensor identifier, and current value included in the measurement data, or items substantially equivalent thereto. The equipment identifier is the identifier of the equipment 3 in which the current sensor 4 is installed. The status is the operating state of the equipment, for example, stopped, idle, or operating.

[0047] The analysis unit 14 can, for example, identify an equipment identifier from a sensor identifier by referring to a table showing the correspondence between sensor identifiers and equipment identifiers, which is pre-stored in the storage unit 15. Note that the sensor identifier and equipment identifier may be the same.

[0048] The analysis unit 14 can determine the status by monitoring the magnitude of the current value of the equipment 3. For example, a first threshold is set to distinguish between stopped and idle, and a second threshold (greater than the first threshold) is set to distinguish between idle and operating. Then, if the measured current value is less than or equal to the first threshold, it is determined to be stopped; if it exceeds the first threshold but is less than or equal to the second threshold, it is determined to be idle; and if it exceeds the second threshold, it is determined to be operating. Taking a temporal element into consideration, for example, multiple collected data 161 for the same equipment 3 may be referenced in a time series, and the status may be updated if the current value remains below or above the threshold for a certain period of time.

[0049] Furthermore, if the operational analysis system uses a power sensor, the current value can be replaced with the power value.

[0050] The collected data 162 concerning workers is generated based on detection data from the beacon receiver 5 and includes time, receiver identifier, equipment identifier, transmitter identifier, and worker identifier. The time, receiver identifier, and transmitter identifier are the detection time, receiver identifier, and transmitter identifier included in the detection data, or items substantially equivalent thereto. The equipment identifier is the identifier of the equipment 3 on which the beacon receiver 5 is installed. The worker identifier is the identifier of the worker 6 on which the beacon transmitter 7 is installed. In other words, the collected data 162 associates equipment 3 with the worker 6 who performs work using equipment 3.

[0051] The analysis unit 14 can, for example, identify an equipment identifier from a receiver identifier by referring to a table showing the correspondence between receiver identifiers and equipment identifiers, which is pre-stored in the storage unit 15. Note that the receiver identifier and equipment identifier may be the same. The analysis unit 14 can also, for example, identify an operator identifier from a transmitter identifier by referring to a table showing the correspondence between transmitter identifiers and operator identifiers, which is pre-stored in the storage unit 15. Note that the transmitter identifier and operator identifier may be the same.

[0052] The collected data 163 related to the work is generated based on detection data from the beacon receiver 5 and includes the time, receiver identifier, equipment identifier, transmitter identifier, and work identifier. The time, receiver identifier, and transmitter identifier are the detection time, receiver identifier, and transmitter identifier included in the detection data, or items substantially equivalent thereto. The equipment identifier is the identifier of the equipment 3 on which the beacon receiver 5 is installed. The work identifier is the identifier of the item 8 on which the beacon transmitter 9 is installed. In other words, the collected data 163 associates equipment 3 with the work (item 8) performed using equipment 3.

[0053] The analysis unit 14 can, for example, identify an equipment identifier from a receiver identifier by referring to a table showing the correspondence between receiver identifiers and equipment identifiers, which is pre-stored in the storage unit 15. Note that the receiver identifier and equipment identifier may be the same. The analysis unit 14 can also, for example, identify an operation identifier from a transmitter identifier by referring to a table showing the correspondence between transmitter identifiers and operation identifiers, which is pre-stored in the storage unit 15. Note that the transmitter identifier and operation identifier may be the same.

[0054] The analysis unit 14 performs various analysis processes on the collected data 16 stored in the storage unit 15, and stores the analysis results as analysis data 17 in the storage unit 15. The UI control unit 12 displays information including at least a portion of the analysis results on the terminal device T. An example of the analysis process will be described in detail below.

[0055] <Example of analysis processing related to equipment> The analysis unit 14 refers to the collected data 161 and calculates the cumulative time for each status for each piece of equipment. The duration of a certain status can be determined, for example, from the difference between the time the status started (start time) and the time the status transitioned to a different status (end time). The cumulative time of a combination of multiple statuses may also be calculated. As an analysis result, for example, if the cumulative time of at least one of the stopped and idle states, or the cumulative time of a combination of stopped and idle states, is displayed for each piece of equipment, the user can understand the amount of time that each piece of equipment is not actually operating (not being used for work).

[0056] The analysis unit 14 calculates the percentage of each status in the total time of all statuses for each piece of equipment. It may also calculate the percentage of a combination of multiple statuses. If the analysis results show, for example, the percentage of the total time spent operating compared to at least one of stopped and idle for each piece of equipment, the user can understand the percentage of time each piece of equipment spends stopped or idle relative to the total time. If the analysis results show, for example, the percentage of the total time spent operating compared to a combination of stopped and idle for each piece of equipment, the user can understand the percentage of time each piece of equipment spends not in operation (not being used for work) relative to the total time.

[0057] The analysis unit 14 refers to the collected data 161 and calculates power values ​​(power W or energy) for each piece of equipment using the current value and a predetermined voltage value (for example, the default voltage value for piece of equipment 3). As an analysis result, for example, if the total value and trend of energy consumption over a predetermined period are displayed for each piece of equipment, the user can understand the trends and peaks of power consumption for each piece of equipment. Of course, current values ​​may be used instead of power values. For example, if the average value and trend of current values ​​over a predetermined period are displayed for each piece of equipment, the user can understand the trends and peaks of current for each piece of equipment. Alternatively, for example, the analysis unit 14 may calculate the energy charge for each piece of equipment using the energy consumption and a predetermined energy charge unit price (for example, provided by the power company). Alternatively, for example, the CO2 emissions may be calculated for each piece of equipment using the energy consumption and a predetermined CO2 emission coefficient (for example, provided by the power company). As an analysis result, if the total value and trend of energy charges and CO2 emissions are displayed for each piece of equipment, the user can understand the trends and peaks of energy charges and CO2 emissions for each piece of equipment.

[0058] If the operational analysis system uses a power sensor, the current value can be replaced with a power value. The analysis unit 14 refers to the collected data 161 and obtains power values ​​(power W or energy) for each piece of equipment. The energy amount for a predetermined period may be calculated using power W. As an analysis result, for example, if the total energy amount and its trend over a predetermined period are displayed for each piece of equipment, the user can understand the trends and peaks of power consumption for each piece of equipment. Similarly, the analysis unit 14 may calculate electricity charges and CO2 emissions for each piece of equipment.

[0059] <Example of analysis processing related to workers> The analysis unit 14 refers to the collected data 162 to identify the start time, end time, and duration of work for each worker at each piece of equipment. For example, if collected data 162 (detection data) for a certain piece of equipment has not been acquired for a certain period of time, the time and worker identifier of the first collected data 162 acquired can be used to identify the start time of the work (work is unidentified) and the worker. Subsequently, if collected data 162 for that piece of equipment has not been acquired for a certain period of time, the time of the last collected data 162 acquired can be used to identify the end time of the work performed by that worker. The duration of work can be calculated from the difference between the start time and the end time. As an analysis result, for example, if the start time and end time of work are displayed for each worker in association with each piece of equipment, the start time, end time, and duration of work for each worker at each piece of equipment can be understood.

[0060] The analysis unit 14 calculates the cumulative working time for each worker at each piece of equipment. It can also calculate the cumulative working time for all equipment at once for each worker. As an analysis result, for example, if the cumulative time for each worker is displayed in relation to each piece of equipment or for all equipment at once, the working time of each worker can be understood.

[0061] <Example of analysis processing related to work> The analysis unit 14 refers to the collected data 163 and identifies the start time, end time, and duration of each task at each piece of equipment. For example, if collected data 163 (detection data) for a certain piece of equipment has not been acquired for a certain period of time, the time and task identifier of the first collected data 163 acquired can be identified as the start time and task of the task (the task has already been identified). Subsequently, if collected data 163 for that piece of equipment has not been acquired for a certain period of time, the time of the last collected data 163 acquired can be identified as the end time of the task. The duration of the task can be calculated from the difference between the start time and the end time. As an analysis result, for example, if the start time and end time of each task are displayed in association with each piece of equipment, the start time, end time, and duration of each task at each piece of equipment can be grasped.

[0062] The analysis unit 14 calculates the cumulative working time for each piece of equipment for each task. It can also calculate the cumulative working time for all equipment for each task. As an analysis result, for example, if the cumulative time for each piece of equipment or for all equipment is displayed for each task, the working time for each task can be understood.

[0063] <Example of analysis processing for two or more of the following: equipment, workers, and tasks> The analysis unit 14 can identify the start time, end time, and duration of each worker's work for each piece of equipment, as described above. It can also identify the start time, end time, and duration of each task for each piece of equipment. Here, if a worker's work time and a task's work time overlap in at least part, the worker and the task may be associated. Alternatively, the status of a worker or task may be identified based on the equipment status. For example, an equipment status of "stopped" or "idling" can be associated with a worker or task status of "preparing," and an equipment status of "operating" can be associated with a worker or task status of "working." As an analysis result, by arbitrarily selecting and associating equipment, equipment status, worker, task, task status, start time, end time, duration, etc., it is possible to grasp the status, start time, etc. of work performed by workers for each piece of equipment.

[0064] The analysis unit 14 may associate the working time of at least one of the workers and tasks with the trend of current values ​​or power values ​​(power watts or energy) for each piece of equipment. As an analysis result, for example, if the trend of current values ​​or power values, and at least one of the workers and tasks and their working time periods are displayed for each piece of equipment in association with the trend, the user can understand the trend and peaks of current consumption or power consumption, along with the time periods during which work was performed for each piece of equipment. In addition, the status of the equipment, or the status of at least one of the workers and tasks, may be displayed along with the trend of current values ​​or power values. Furthermore, if there are tasks for which the end time is not specified, they may be counted and displayed as the number of tasks that have not been started or are in progress (number of pending tasks).

[0065] Figure 3 is a flowchart illustrating an example of the data collection process for the equipment according to this embodiment. This flowchart is executed, for example, each time the operation analysis device 1 receives output data from the current sensor 4.

[0066] The acquisition unit 13 acquires output data from the current sensor 4 via the communication unit 18 (step S01). The analysis unit 14 generates collected data 161 based on the output data acquired by the acquisition unit 13 and stores it in the storage unit 15 (step S02). Specifically, as described above, the analysis unit 14 determines and adds an equipment identifier corresponding to the sensor identifier, and determines and adds a status based on the current value.

[0067] Furthermore, if the operational analysis system uses a power sensor, the current value can be replaced with the power value.

[0068] Figure 4 is a flowchart illustrating an example of the data collection process for workers according to this embodiment. This flowchart is executed, for example, each time the work analysis device 1 receives output data from the beacon receiver 5.

[0069] The acquisition unit 13 acquires output data from the beacon receiver 5 via the communication unit 18 (step S11). In this step, the acquisition unit 13 acquires the output data if the transmitter identifier included in the output data is the identifier of the beacon transmitter 7 installed at the worker's location or is associated with a worker identifier.
