  In the present embodiment, the control unit 41 includes a data acquisition unit (data acquisition unit) 51, a display control unit (display control unit) 52, and an instruction signal transmission unit (signal transmission unit) 53 as functional blocks. Each of the functional blocks (51 to 53) of the control unit 41 is executed by the CPU reading a program stored in a storage device realized by a ROM or the like to a temporary storage unit realized by a RAM or the like and executing the program. realizable.

  The data acquisition unit 51 acquires the measurement data 70 and the processed data 90 from the data collection / holding device 1 via the communication unit 43 at a predetermined cycle. The data acquisition unit 51 acquires at least power consumption data 71, production number data 81, and facility physical quantity data 82. Here, a cycle in which the data acquisition unit 51 acquires each data is referred to as an acquisition cycle.

  The data acquisition part 51 may acquire each data according to the measurement period of each data. That is, the acquisition cycle of each data may be a measurement cycle. Moreover, the data acquisition part 51 may acquire each data of the said production equipment 3 according to the process time which is the time concerning one process which the production equipment 3 performs, or the time of the natural number times of the said process time. .

  In addition, the data acquisition unit 51 may acquire the management value setting table 32 via the communication unit 43. The data acquisition unit 51 may acquire the history data 31 held by the data collection and holding device 1 via the communication unit 43 via the communication unit 43.

  The display control unit 52 displays each data (measurement data 70, processing data 90, and history data 31) acquired by the data acquisition unit 51 as a graph on the display unit 44 in real time. The display control unit 52 simultaneously displays at least the power consumption amount data 71, the production number data 81, and the equipment physical quantity data 82 on the display unit 44. In other words, the display control unit 52 displays the history of the power consumption, the number of productions, and the equipment physical quantity on the same screen, and updates the display contents at a predetermined cycle. Here, the cycle in which the display control unit 52 updates the display is referred to as an update cycle.

  The update cycle in which the display control unit 52 updates the display may be the measurement cycle described above, or may be a time that is a natural number times the process time, which is the time taken for one process executed by the production facility 3. Good.

[Display screen example]
Next, an example of a power amount display screen showing the power consumption amount and the like of the production facility 3 displayed on the display unit 44 of the terminal 2 will be described with reference to FIGS. Here, it is assumed that the factory 7 has three lines “clean room”, “SMT”, and “IC package”, and each line is composed of one or a plurality of production facilities 3.

  First, an example of an electric energy display screen showing the electric energy consumption of the factory 7 as a whole will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of the power amount display screen 101 indicating the power consumption and the like of the factory 7 as a whole.

  As shown in FIG. 4, the power amount display screen 101 has three areas. That is, the electric energy display screen 101 includes a first data display area 111, a second data display area 112, and a production facility arrangement display area 113. In the first data display area 111, a graph of each data is displayed. In the second data display area 112, the power consumption amount and the like are displayed numerically. In the production facility layout display area 113, a layout diagram of the production facility 3 in the factory 7 is displayed.

  In the example shown in FIG. 4, three graphs are displayed in the first data display area 111. Specifically, a graph 124 showing the total power consumption of all the production facilities 3 in the factory 7, the cumulative power consumption of all the production facilities 3 in the factory 7, and the lines in the factory 7 or each production facility A graph 125 indicating the total number of productions and a graph 126 indicating the amount of particles in a line in the factory 7 or each production facility are displayed.

  In addition, management values are also drawn on the graphs 124, 125, and 126, respectively. Specifically, the target value of the total power consumption of all the production facilities 3 in the factory 7 is drawn on the graph 124. In addition, in the graph 125, the cumulative target value of the power consumption of all the production facilities 3 in the factory 7 is drawn. In addition, an appropriate range (upper limit value) of the particle amount of each production facility in the factory 7 is drawn on the graph 126.

  In the example shown in FIG. 4, there is a time axis change tab in the first data display area 111, and the “today” tab 121 is currently selected. Therefore, each graph 124, 125, 126 is drawn with data in units of one day. That is, in the graph 124, the total power consumption of all the production facilities 3 in the factory 7 from 0:00 to 24:00 today is drawn. Further, in the graph 125, the cumulative power consumption of all the production facilities 3 in the factory 7 from 0:00 to 24:00 today is drawn. In the graph 126, the particle amount of each production facility in the factory 7 from 0:00 to 24:00 today is drawn.

  The unit of the time axis of the graph in the first data display area 111 can be changed by selecting the “current month” tab 122 or the “current year” tab 123 from the screen state shown in FIG.

  In the example shown in FIG. 4, the second data display area 112 displays the current power consumption, the past power consumption, the target value of the power consumption, and the efficiency with respect to the target value. Specifically, today's power consumption (power consumption), yesterday's power consumption, target value of power consumption for one day (24 hours), and current efficiency for today's target value are displayed. Here, the efficiency is the ratio of the current power consumption to the target value of power consumption. That is, as the efficiency is smaller than 100%, energy saving can be achieved, and when the efficiency is larger than 100%, the target is not achieved.

  In the example shown in FIG. 4, the power value (kwh) of the power consumption amount is drawn in the second data display area 112, and the amount of money (yen) obtained by converting the power amount into an electric charge is also written. Yes. The time unit such as the power consumption drawn in the second data display area 112 is linked to the first data display area 111. In the example shown in FIG. 4, since the “today” tab 121 is selected, the daily power consumption amount is also displayed in the second data display area 112.

  Note that the basic unit power consumption may be displayed in the second data display area 112. Moreover, you may display the value which converted the electric energy into the discharge | emission amount of the carbon dioxide instead of the electricity bill. Further, if the current power consumption (actual value) is less than the target value of power consumption, a difference value (extra amount) between the target value and the actual value may be displayed.

  In the example shown in FIG. 4, the production facility layout display area 113 displays a line of the entire factory 7 and a layout diagram of the production facility 3. In the production facility arrangement display area 113, icons (for example, icons 132) indicating the states of the respective lines and the respective production facilities 3 are drawn on the arrangement drawing. The production facility arrangement display area 113 includes a case display area 131 for explaining the legend of the icon.

  The icons indicating the state of each line and each production facility 3 are circular and are divided into four regions. Each region indicates whether or not the power consumption amount, the particle amount, the air flow rate, and the temperature and humidity values are within appropriate ranges. Here, it is assumed that the power consumption amount, the particle amount, the air flow rate, and the temperature / humidity values are indicated by colors. Specifically, if the area is blue, each value is a normal value. Also, if the region is yellow, each value is within the proper range but close to the critical value of the proper range. Further, if the area is red, each value is out of the proper range and is an abnormal value. If the area is gray, it indicates that no sensor for measuring the value is installed. Note that “close to the critical value of the appropriate range” may be defined as a range of 80% or more and less than 100% of the upper limit value or lower limit value of the appropriate range, for example.

  In the example illustrated in FIG. 4, the power consumption value of the production facility 3 to which the icon 134 is added is abnormal.

  In addition, a display target change tab for changing a target to be displayed on the screen to a factory, a floor (room), a line, or a production facility is displayed in the production facility arrangement display area 113. In the example shown in FIG. 4, display target change tabs 141, 142, and 143 for changing the display target to each line are displayed.

  For example, when the user selects the display object change tab 141, the layout diagram in the clean room is enlarged and displayed in the production facility layout display area 113. In the first data display area 111 and the second data display area 112, the amount of power consumed by the clean room or the production facility 3 in the clean room is displayed. Instead of selecting the display object change tab, the display object may be changed by selecting a line on the layout drawing or the production facility 3.

  Next, an example of the power amount display screen displayed when the “this month” tab 122 is selected from the state where the power amount display screen shown in FIG. 4 is displayed will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of the power amount display screen 102 that shows the power consumption amount of the entire factory 7 in units of months.

  As shown in FIG. 5, each of the graphs 151, 152, and 153 displayed in the first data display area 111 is drawn with data for each month. That is, in the graph 151, the total power consumption of all the production facilities 3 in the factory 7 from the 1st to the 31st (the last day) of this month is drawn. In the graph 152, the cumulative power consumption of all the production facilities 3 in the factory 7 from the 1st to the 31st (the last day) of this month is drawn. In the graph 153, the particle amount of each production facility in the factory 7 is drawn from the first day to the 31st (the last day) of this month.

  In addition, since the “current month” tab 122 is selected, the power consumption amount displayed in the second data display area 112 is also displayed on a monthly basis in conjunction with the first data display area 111. Specifically, the power consumption of this month (power consumption), the power consumption of last month, the target value of the monthly power consumption, and the current achievement rate with respect to the target value of this month are displayed.

  Next, based on FIG. 6, an example of the power amount display screen displayed when the display target change tab 143 (“IC package” line) is selected from the state where the power amount display screen shown in FIG. 4 is displayed. explain. FIG. 6 is a diagram illustrating an example of the power amount display screen 103 indicating the power consumption amount of the production facility in the IC package.

  As shown in FIG. 6, the production facility layout display area 113 displays an enlarged layout diagram of each production facility 3 in the IC package. In addition, an icon indicating the state of the entire IC package line and an icon indicating the state of each production facility are displayed. At this time, a display object change tab 144 for returning to the factory whole display is displayed as the display object change tab.

  In the example shown in FIG. 6, five graphs are displayed in the first data display area 111. Specifically, a graph 161 indicating the total power consumption of all the production facilities 3 in the IC package, and a graph indicating the total power consumption of all the production facilities 3 in the IC package and the total number of IC packages produced. 162, a graph 163 showing the particle amount of each production facility in the IC package, a graph 164 showing the temperature and humidity of each production facility in the IC package, and a graph 165 showing the air flow rate of each production facility in the IC package, Is displayed.

  Further, in the example shown in FIG. 6, the second data display area 112 displays the power consumption (power consumption) of the entire today IC package, the power consumption of the entire yesterday IC package, and IC for one day (24 hours). The target value of the power consumption of the entire package and the current achievement rate with respect to the target value of today for the entire IC package are displayed. Here, the power consumption is displayed in basic units, that is, a value obtained by dividing the power consumption of the entire IC package by the number of IC packages produced is displayed.

  Next, an example of a management value setting screen displayed on the display unit 44 when the user sets a management value will be described with reference to FIG. FIG. 7 is a diagram illustrating an example of a management value setting screen displayed when setting a management value.

  The management value setting screen shown in FIG. 7 is for setting a target value for the power consumption of the production facility “DB2”. In the area 201, the actual value and target value of the monthly power consumption of the production facility “DB2” are displayed. In the area 202, the actual value and the target value of the power consumption every 10 minutes are displayed. In areas 201 and 202, “current setting” is the target value of the power consumption that is currently set, and “new setting” is the target value that is newly set.

  By inputting a value in “new setting” in the areas 201 and 202, the user can set a new target value. Further, as displayed in the areas 203 and 204, a new target value can be set based on the currently set target value or the past actual value. Specifically, in the illustrated example, a new target value can also be set by inputting a target value that is currently set or a ratio to a past actual value.

[Another example of management value setting processing]
In the example shown in FIG. 7, for each hour (every 10 minutes) in a day, a new management value is automatically set by performing a specific calculation with reference to the current management value or the past one month. It is possible to do. On the other hand, an example in which the management value calculation setting process performed by the management value setting unit 24 can be performed in more detail will be described below.

  FIG. 11 shows an example of a parameter setting screen for setting various parameters when the management value setting unit 24 performs the management value calculation. For example, a parameter setting screen calling button may be provided on the parameter setting screen in the management value setting screen shown in FIG. 7, and the parameter setting screen may be called when the user presses this button.

  As shown in FIG. 11, the parameter setting screen displays, as parameters, setting values related to a management value calculation target month, a reference period, a target day type, a calculation type, and a correction amount. Note that the parameters are not limited to these, and all of them are not essential.

  The management value calculation target month indicates a parameter for setting a month as a target period during which the management value calculation is performed. In this example, the target period in which the management value calculation is performed is specified in units of months, but the period may be specified in units of days. That is, the start date and the end date of the target period for which the management calculation is performed may be specified.

  The reference period indicates a parameter for setting a period to be referred to as a past record when the management value calculation is performed. That is, the management value setting unit 24 performs management calculation by reading data included in the reference period from the history data 31 stored in the storage unit 12.

  Options for the reference period include, but are not limited to, “previous month”, “same month in the previous year”, and “designated period”. “Previous month” is a case where the previous month of the management value calculation target month is set as the reference period. In this case, the management value calculation can be performed based on a comparison with the results of the previous month. “Same month in the previous year” is a case where the same month one year before the management value calculation target month is set as the reference period. For example, in the case of power consumption, since the numerical value tends to vary depending on the season, it is possible to set a management value corresponding to the season by selecting “same month last year”. “Specified period” is a case where the reference period is specified by the start date and the end date. For example, when a specific production is performed in a specific period in the past based on a production plan or the like, it is possible to set a management value corresponding to the actual result in the specific period. Therefore, the application range of target value management at the site of FA (Factory Automation) can be widened. Note that the reference period may be specified by a specific year, a specific week, or the like.

  The target day type indicates a parameter that specifies the type of the day in which the actual results are referred to in the reference period. Examples of the target day type include “same day of the week” and “weekday / holiday”, but are not limited thereto. “Same day of the week” is a case where the management value calculation is performed on each day of the management value calculation target month based on the results of the same day of the reference period. For example, when the production status changes depending on the day of the week, it is possible to set a management value corresponding to each day of the week by selecting this “same day”. “Weekdays / Holidays” is a management value calculation based on the weekday results in the reference period if it is a weekday on each day of the management value calculation target month. This is a case where the management value calculation is performed based on. For example, when the production status changes depending on whether it is a weekday or a holiday, it is preferable to select this “weekday / holiday”. Note that “weekdays” and “holidays” may be days specified by a calendar, “weekdays” may be “production equipment operating days”, and holidays may be “production equipment non-working days”.

  The calculation type indicates a parameter that specifies the type of calculation performed on past performance data. Examples of the calculation type include “average value”, “maximum value”, and “minimum value”, but are not limited thereto.

  The correction amount indicates a parameter for designating a correction amount to be performed on a value obtained by performing the calculation according to the calculation type based on the history of the reference period. Examples of the correction amount include “change ratio” and “offset”, but are not limited thereto. “Change ratio” is a case in which a ratio to be set as a management value with respect to a value of a calculation result is designated. For example, when “change ratio” is designated as 90%, a value of 90% is set as a management value for the value of the calculation result. “Offset” is a case where a predetermined value is specified to be added or subtracted with respect to the value of the calculation result. For example, when “offset” is set to −0.01 kwh, a value obtained by subtracting 0.01 kwh from the value of the calculation result is set as the management value.

  When the “Setting” button is pressed by the user after the above various parameters are specified, the management value setting unit 24 performs management value calculation based on the specified various parameters, and the calculation result is stored in the management value setting table 32. Is stored in the storage unit 12.

  In the above processing, for example, processing for the next month may be performed at the end of the previous month. Moreover, in the example shown in FIG. 11, although the management value calculation object month is made into the specific month, this may be made into a period. In this case, for example, if the management value calculation target is one year, it is possible to collectively execute management value calculations for one year based on historical data for the previous year.

  In the example shown in FIG. 11, the case of the target value of the power consumption is described as the management value calculation target. However, the present invention is not limited to this, and the same applies to the appropriate ranges of the facility physical quantity and the environmental physical quantity. The management value calculation may be performed.

  According to the above management value calculation, since the setting of the management value is automated, the user only has to manage the daily energy consumption, and the management effort of the user can be greatly reduced. In addition, since the target period for calculating the target value can be arbitrarily specified relatively, it is possible to deal with various fluctuation models such as seasonal fluctuations and daily working hours. Therefore, the application range of the management value automatic setting can be widened.

[Processing flow of data collection and holding device and terminal]
Next, the processing flow of the data collection and holding device 1 and the terminal 2 will be described with reference to FIGS. First, the processing flow of the data collection and holding device 1 will be described with reference to FIGS. FIG. 8 is a flowchart illustrating an example of the flow of data collection processing of the data collection and holding device 1. FIG. 9 is a flowchart showing an example of the data transmission processing flow of the data collection and holding device 1.

  As shown in FIG. 8, the data collection unit 21 of the data collection and holding device 1 collects the measurement data 70 from each data measurement device 4 in accordance with the measurement cycle (S1). Next, the data processing unit 22 generates new data (processed data 90) from the collected measurement data 70 (S2).

  The data collection unit 21 stores the collected measurement data 70 as the history data 31 in the storage unit 12, and the data processing unit 22 stores the generated processed data 90 as the history data 31 in the storage unit 12 (S3). And it waits for a predetermined measurement period to pass (S4), and collects measurement data 70 from each data measuring device 4 again.

  On the other hand, as shown in FIG. 9, the data collection and holding device 1 waits for a signal requesting data from the terminal 2 while executing the data collection processing (S11). When the data collection and holding device 1 receives a signal requesting data from the terminal 2, the data transmission unit 23 transmits the collected measurement data 70 and the processed data 90 generated from the measurement data 70 to the terminal 2 (S12). .

  When the data collection / holding apparatus 1 receives a signal requesting the history data 31 or the management value setting table 32 from the terminal 2, the data collection / holding apparatus 1 transmits the history data 31 or the management value setting table 32 to the terminal 2 in response to the request. In addition, when the management value setting table 32 is updated, the data collection and holding device 1 may transmit the updated management value setting table 32 to the terminal 2.

  Next, the processing flow of the terminal 2 will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of the processing flow of the terminal 2.

  As shown in FIG. 10, the data acquisition unit 51 of the terminal 2 acquires the measurement data 70 and the processed data 90 from the data collection and holding device 1 at a predetermined acquisition cycle (S21). The display control unit 52 creates an electric energy display screen based on the acquired measurement data 70 and processing data 90 (S22). Next, the display control unit 52 displays the generated power amount display screen on the display unit 44 (S23). Then, it waits for a predetermined update period to elapse (S24), and again acquires the measurement data 70 and the processed data 90 from the data collection and holding device 1, and updates the display.

  As described above, the terminal 2 displays the history of the power consumption, the production number, and the equipment physical quantity indicated by the acquired power consumption data, the production number data, and the equipment physical quantity data on the same screen, and displays the display contents in a predetermined cycle. Update with. Therefore, every time the display is updated, the user can simultaneously confirm the power consumption, the number of productions, and the physical quantity of equipment and changes at that time. Therefore, based on the displayed information, the user can take actions to maintain productivity and quality and save power while being displayed.

  Here, for example, when the update cycle at which the terminal 2 updates the display is synchronized with the measurement cycle for measuring the power consumption, the number of productions, and the equipment physical quantity, the user can The value and change of the number and physical quantity of equipment can be confirmed simultaneously. Therefore, the user can take action in real time to maintain the productivity and quality and to save power based on the power consumption amount, the production number, and the physical quantity of the current production facility.

  Further, since the terminal 2 displays the current and past values of the equipment physical quantity, the user attempts to improve the environmental state of the production equipment (for example, the amount of particles in the clean room, etc.) based on the value and change of the equipment physical quantity. Can take action for.

[Management value judgment processing]
In the above example, in the terminal 2, the display control unit 52 displays the target value of the power consumption amount on the power consumption amount graph based on the management value setting table 32 acquired by the data acquisition unit 51. The appropriate range of the physical quantity of equipment is displayed on the equipment physical quantity graph. By confirming this graph, the user recognizes that the amount of power consumption has exceeded the target value or that the equipment physical quantity is out of the appropriate range.

  On the other hand, when the power consumption exceeds the target value, or when the equipment physical quantity or the environmental physical quantity is out of the appropriate range, an alarm may be issued to notify the user to that effect. . FIG. 12 shows the configuration of the data collection and holding device 1 in which this alarm processing is performed. As shown in the figure, the control unit 11 includes a management value determination unit 25 in addition to the configuration shown in FIG.

  The management value determination unit 25 receives the measurement data 70 from the data collection unit 21 and the processing data 90 from the data processing unit 22 and reads the management value setting table 32 from the storage unit 12. Then, the management value determination unit 25 compares the measurement data 70 and the processing data 90 with the management value setting table 32, and whether or not the power consumption exceeds the target value, or the facility physical quantity or the environmental physical quantity is in an appropriate range. It is determined whether or not it is out of the range. In addition, the management value determination part 25 should just monitor at least any one of power consumption, an equipment physical quantity, and an environmental physical quantity. Moreover, the management value determination part 25 may receive any one of the measurement data 70 and the process data 90 as needed.

  When the management value determination unit 25 determines that the power consumption exceeds the target value, or the facility physical quantity or the environmental physical quantity is out of the appropriate range, the management value determination unit 25 transmits the fact to the data transmission unit 23. In this case, the data transmission unit 23 transmits to the terminal 2 via the communication unit 13 as alarm information that the power consumption exceeds the target value or that the facility physical quantity or the environmental physical quantity is out of the appropriate range.

  On the other hand, if the management value determination unit 25 determines that the power consumption does not exceed the target value and that the facility physical quantity and the environmental physical quantity are not out of the appropriate ranges, the measurement data 70 and the processed data 90 are directly used as data. Transmit to the transmitter 23.

  When the terminal 2 receives the alarm information from the data collection and holding device 1 via the communication unit 43, the display control unit 52 of the control unit 41 displays an alarm based on the alarm information on the display unit 44. As this alarm display, for example, blinking display is conspicuously displayed on the display screen indicating that the power consumption exceeds the target value, or that the equipment physical quantity or the environmental physical quantity is out of the appropriate range. In addition to this alarm display, a sound indicating an alarm may be output.

  In normal times, when the data collection and holding device 1 receives a signal requesting data from the terminal 2, the data transmission unit 23 transmits the measurement data 70 and the processed data 90 to the terminal 2, but an alarm is issued. Sometimes, when the management value determination unit 25 determines an alarm, the data transmission unit 23 may transmit the alarm information to the terminal 2. In this case, the alarm process can be performed earlier.
