Description

  The present invention relates to a living action display device, a living action display system, a living action display method, and a program.

  Due to the increase in the number of nuclear family households and the diversification of lifestyles, the number of members constituting one household tends to decrease. In addition, with the globalization of the economy, the ratio of single employees to the working population is expected to increase. For this reason, research and development are actively performed about the technique for confirming the state of a family or close relative from a distance (for example, refer nonpatent literature 1).

  Non-Patent Document 1 describes that fluctuations in electric power (total load current) used in a residence serve as a useful index for determining the presence or absence of a living behavior of a resident. In the system disclosed in Non-Patent Document 1, the result of estimating the presence / absence of living behavior based on the fluctuation of electric power is shown.

  When the user checks the resident's state from outside the house, not only the presence / absence of the current living behavior but also a lot of time series data is often referred to as past history. The data referred to in this case is desirably presented so that the listability is high. When the listability of the presented data is high, the user can intuitively understand the state of the resident without overlooking abnormalities included in a large number of data. Thus, for example, it is conceivable to use the technique described in Patent Document 1.

  The system disclosed in Patent Literature 1 displays a symbol corresponding to each of a plurality of sensors on a screen in a color, size, or shape corresponding to the output value of each sensor. The user can easily grasp the state of the space in which the sensors are dispersedly arranged by viewing this screen.

"System for watching elderly living alone from the use of electricity (Part 2)-Method using cumulative frequency distribution of changes in total load current-", Central Research Laboratory Research Report (R05013), 2006

  However, since the power usage situation varies greatly depending on the home, if an inappropriate parameter is set in the system described in Non-Patent Document 1, there is a possibility that the estimation accuracy of the presence or absence of living activities may be reduced. Therefore, in this system, it is necessary to set an appropriate parameter in advance for each home. Moreover, when the presence / absence of living behavior is erroneously estimated, the technique described in Patent Literature 1 may promote misrecognition by the user.

  If it is known that the presence / absence of living behavior may be erroneously estimated, the user can determine the resident's state by referring to raw data such as the amount of power fluctuation. However, such a determination is not only a complicated task but also a very difficult task for a non-expert user.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to display information capable of intuitively grasping a resident's state without forcing a user to perform special work.

  In order to achieve the above object, the living behavior display device of the present invention shows fluctuations in the value of electric power in each of a plurality of different periods from the calculating means for calculating based on the transition of the value of electric power supplied to the house. Acquisition means for acquiring fluctuation data, display means for displaying an image pattern relating to the value of power supplied to the house for each of a plurality of periods, setting means for setting a time axis on the screen, and setting means And a pattern changing unit that arranges each image pattern along the time axis set by the step of changing the attribute of each of the arranged image patterns according to the variation data acquired by the acquiring unit.

  According to the present invention, the attribute of the image pattern changes according to the variation data. The user can determine the presence / absence of living behavior in the house by this change. Therefore, it is possible to display information that can intuitively grasp the state of the resident.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 shows a daily activity display system 100 according to the first embodiment. This living behavior display system 100 displays information for the user U1 outside the home to determine the presence or absence of behavior of a resident living in the house H1. Hereinafter, the behavior of the resident of the house H1 is referred to as a living behavior. Living behavior includes, for example, the use of meals, excretion, bathing and other electrical equipment. It is assumed that various electric devices used for living activities are installed in the house H1.

  The living behavior display system 100 uses the power meter 10 that measures the power supplied to the house H1, the arithmetic device 20 that performs a calculation based on the measurement result by the power meter 10, and the calculation result by the arithmetic device 20. It has a daily activity display device 30 that displays information to the user U1.

  The power meter 10 is installed in the distribution board 11 of the house H1. The power meter 10 stores a power sensor that measures power, an MCU (Micro Controller Unit) that processes sensor values output from the power sensor, a first flash memory that stores a program executed by the MCU, and various data. And a second flash memory, an RTC (Real Time Clock) that outputs the current date and time, and the like. Note that the first and second flash memories may be configured by dividing the address of one flash memory.

  The power meter 10 measures an instantaneous value of power supplied from the commercial power supply 12 via the lead-in line 13 to the load 14 in the house H1 at a preset period. This period is, for example, 10 seconds. Since the load 14 is, for example, an electric device used by a resident, the value of power measured by the power meter 10 is equal to the value of power consumed by the living behavior of the resident.

  The power meter 10 sequentially stores the measured power value in the flash memory as power data 10d in association with the measured time. In the flash memory, the transition of the value of power supplied to the house H1 is stored as time-series power data 10d.

  When there is an inquiry from the computing device 20, the power measuring instrument 10 reads the power data 10 d from the flash memory and transmits it to the computing device 20 via a wired or wireless communication path. This communication path may be a dedicated line for one-to-one communication using a specific protocol, or may be a network such as a LAN (Local Area Network).

The computing device 20 is, for example, a computer terminal installed in the house H1. The arithmetic unit 20 calculates the degree of power fluctuation based on the power data 10d.
As shown in FIG. 1, the arithmetic unit 20 includes a processor 21 that executes arithmetic processing, a main storage unit 22 that is used as a work area of the processor 21, and a first auxiliary storage unit that stores a program P2 executed by the processor 21. 23, a second auxiliary storage unit 24 that stores fluctuation data 24d indicating the result of the calculation by the processor 21, an RTC 25 that outputs the current date and time, a timer 26 that notifies the processor 21 of periodic timing, and an external device An interface unit 27 for communication is provided. The main storage unit 22, the first auxiliary storage unit 23, the second auxiliary storage unit 24, the RTC 25, the timer 26, and the interface unit 27 are all connected to the processor 21 via the internal bus 201.

  The processor 21 is composed of, for example, an MCU. The main storage unit 22 is composed of, for example, a RAM. The main storage unit 22 loads the program P2 stored in the first auxiliary storage unit 23. The first auxiliary storage unit 23 and the second auxiliary storage unit 24 include a nonvolatile memory such as a flash memory, for example. The first auxiliary storage unit 23 and the second auxiliary storage unit 24 may be configured by dividing addresses of one storage device.

  In response to a request from the processor 21, the RTC 25 notifies the processor 21 of the current date and time. The timer 26 outputs a signal serving as a trigger for starting processing by the processor 21 to the processor 21 at a constant cycle. This period is, for example, 1 hour.

  The interface unit 27 includes a communication interface for communicating with the power meter 10 and the daily activity display device 30. The interface unit 27 requests the power meter 10 to output the power data 10d according to the instruction of the processor 21. Then, the interface unit 27 receives the power data 10 d output from the power meter 10 and transmits it to the processor 21. Further, the interface unit 27 transmits the variation data 24d to the living behavior display device 30 through a wired or wireless communication path according to an instruction from the processor 21. This communication path includes, for example, the Internet.

  The living behavior display device 30 is, for example, a mobile terminal such as a smartphone owned by the user U1. As shown in FIG. 1, the daily activity display device 30 includes a processor 31 that executes display processing, a main storage unit 32 that is used as a work area of the processor 31, and an auxiliary storage unit that stores a program P3 executed by the processor 31. 33, an RTC 35 that outputs the current date and time, a timer 36 that notifies the processor 31 of periodic timing, an interface unit 37 for communicating with an external device, an input unit 38 for the user U1 to input parameters, and It has the display part 39 which displays information with respect to the user U1. The main storage unit 32, auxiliary storage unit 33, RTC 35, timer 36, interface unit 37, input unit 38, and display unit 39 are all connected to the processor 31 via the internal bus 301.

  The processor 31 is composed of, for example, an MCU. The main storage unit 32 is constituted by, for example, a RAM or the like. The main storage unit 32 loads the program P3 stored in the auxiliary storage unit 33. The auxiliary storage unit 33 includes a nonvolatile memory such as a flash memory.

  The RTC 35 notifies the processor 31 of the current date and time in response to a request from the processor 31. The timer 36 outputs a signal serving as a trigger for displaying an animation by updating the displayed static information to the processor 21 at a constant cycle. This period is 1/30 seconds, for example.

  The interface unit 37 includes a communication interface for communicating with the arithmetic device 20. The interface unit 37 requests the arithmetic device 20 to output the variation data 24d in accordance with an instruction from the processor 31. Then, the interface unit 37 receives the fluctuation data 24 d output from the arithmetic device 20 and transmits it to the processor 31.

  The input unit 38 includes, for example, an input key and a capacitance type pointing device. The input unit 38 acquires a parameter designated by the user U1 and notifies the processor 31 of the parameter.

  The display unit 39 includes a screen 391 such as a liquid crystal display that displays characters and graphics, and a VRAM (Video RAM) 392 that temporarily holds contents displayed on the screen 391. The screen 391 according to the present embodiment is formed integrally with a pointing device that constitutes the input unit 38 to constitute a touch screen. Note that the main storage unit 32 and the VRAM 392 may be configured by dividing one RAM address.

  The daily activity display device 30 performs various functions by executing the program P3 using hardware resources such as the processor 31, and draws characters and figures on the screen 391. As shown in FIG. 2, the life activity display device 30 has, as its function, a time axis setting unit 310 that sets a time axis on a screen 391, a pattern changing unit 320 that changes a pattern displayed on the screen 391, and The non-reaction time presentation unit 330 presents a time during which no living behavior is detected.

  FIG. 3 shows an example of contents drawn on the screen 391 by the time axis setting unit 310, the pattern changing unit 320, and the no-reaction time presenting unit 330. This screen 391 includes an area 40 for displaying power value fluctuations and an area 50 for displaying messages.

  The time axis setting unit 310 is mainly realized by the processor 31. The time axis setting unit 310 sets the time axis 41 composed of one line in the area 40 as shown in FIG. The time axis 41 according to the present embodiment is composed of a visible straight line and an invisible straight line that are alternately connected, and is displayed by being folded.

  The pattern changing unit 320 is mainly realized by the processor 31 and the interface unit 37. The pattern changing unit 320 arranges a plurality of image patterns 48 along the time axis 41 as shown in FIG. The image pattern 48 according to the present embodiment is a circular icon indicating a shaded sphere. The pattern changing unit 320 changes the attribute of the arranged image pattern 48 over time based on the variation data 24d. In the present embodiment, the size of each icon changes as an attribute of each image pattern 48.

  The no-reaction time presentation unit 330 is realized mainly by the processor 31 and the interface unit 37. The no-reaction time presentation unit 330 detects the fluctuation of power as a reaction caused by the living behavior of the resident from the fluctuation data 24d. In addition, the no-reaction time presentation unit 330 calculates a time during which the fluctuation of the power is not continuously detected until the current time. This time is hereinafter referred to as no reaction time. Then, the no-reaction time presentation unit 330 notifies the user U1 of the no-reaction time by presenting a message for informing the no-reaction time to the area 50.

  Next, the calculation process executed by the calculation device 20 and the display process executed by the living behavior display device 30 will be described with reference to FIGS.

  FIG. 4 shows a flow of arithmetic processing. This arithmetic processing starts when the arithmetic device 20 is turned on.

  As shown in FIG. 4, the processor 21 of the arithmetic unit 20 first determines whether or not the timing is notified from the timer 26 (step S1). The timer 26 according to the present embodiment notifies a periodic timing to the processor 21 by transmitting a signal serving as a trigger for executing the processing after step S2 at 0 minutes per hour. For this reason, in step S1, the processor 21 determines whether or not the current time corresponds to 0 minutes per hour.

  When it is determined that the timing has not been notified (step S1; No), the processor 21 proceeds to step S7 without executing step S2.

  On the other hand, when it is determined that the timing has been notified (step S1; Yes), the processor 21 determines an end time Te (step S2). The end time Te determined in step S2 is the current time.

  Next, the processor 21 requests the power meter 10 to output power data 10d for P hours (step S3). Specifically, the processor 21 requests the output of the power data 10d measured in the P time until the end time Te. In the present embodiment, the processor 21 requests data for one hour.

  Next, the processor 21 receives the power data 10d from the power meter 10 and stores it in the main storage unit 22 in the order of measurement (step S4). Hereinafter, the number of data stored in the main storage unit 22 is assumed to be x. In the present embodiment, since the power meter 10 measures power every 10 seconds, the value of x is 360 (1 hour / 10 seconds).

  Next, the processor 21 calculates values of L [1] to L [k] from the x pieces of data stored in the main storage unit 22 (step S5). Each of L [1] to L [k] is a feature amount indicating the magnitude of a periodic fluctuation having a period of a certain length as a period. The values (1 to k) in parentheses are numbers that are consecutively assigned in order of increasing cycle. For example, the cycle corresponding to L [1] is shorter than the cycle corresponding to L [2], and the cycle corresponding to L [2] is shorter than the cycle corresponding to L [3]. The time corresponding to the period corresponding to L [1] to L [k] is hereinafter referred to as power fluctuation time for convenience. Hereinafter, the calculation procedure of L [1] to L [k] will be specifically described with reference to FIG.

  5, each of instantaneous values N [1] 1, N [1] 2,..., N [1] x indicated by black circles is equal to a measured value extracted from the power data 10d. That is, the thick broken line connecting the black circles in FIG. 5 indicates the transition of the power supplied to the house H1 during the P time until the end time Te. For example, when the end time Te is exactly 11 o'clock, the instantaneous value N [1] 1 is a value measured at 10:00:00 and the instantaneous value N [1] x is 11:00:00 The value is measured at minute 0 second.

  Next, the processor 21 sequentially calculates an average value of two adjacent instantaneous values, thereby calculating an average value N [2 from a series N [1] including the instantaneous values N [1] 1 to N [1] x. ] A sequence N [2] consisting of 1 to N [2] x is calculated. For example, the processor 21 calculates the average value N [2] 1 by dividing the sum obtained by adding the instantaneous value N [1] 2 to the instantaneous value N [1] 1 by 2. Further, the processor 21 calculates an average value N [2] 2 from the instantaneous value N [1] 2 and the instantaneous value N [1] 3. Similarly, the processor 21 calculates average values N [2] 3 to N [2] x-1.

  In FIG. 5, each average value constituting the series N [2] is indicated by a circle surrounded by a white dotted line. Further, the thick dotted line in FIG. 5 indicates the series N [2].

  Note that the processor 21 sets a value equal to the instantaneous value N [1] x as the average value N [2] x. However, in FIG. 5, the instantaneous value N [1] x and the average value N [2] x are drawn as different values for the sake of explanation. Thereafter, the processor 21 stores the sequence N [2] in the main storage unit 32.

  Next, the processor 21 calculates a sequence M [1] including the differences M [1] 1 to M [1] x from the sequences N [1] and N [2]. For example, the processor 21 calculates the difference M [1] 1 by subtracting the instantaneous value N [1] 1 from the average value N [2] 1. Further, the processor 21 subtracts the instantaneous value N [1] 2 from the average value N [2] 2 to obtain a difference M [1] 2. Similarly, the processor 21 calculates the differences M [1] 3 to M [1] x.

  In FIG. 5, each difference constituting the sequence M [1] is indicated by a thick arrow. Each difference indicates the amount of change from one instantaneous value to the next measured instantaneous value. For example, the difference M [1] 1 indicates the amount of change from the instantaneous value N [1] 1 to the instantaneous value N [1] 2.

  Next, the processor 21 calculates absolute values | M [1] 1 | to | M [1] x | of the differences M [1] 1 to M [1] x. Each of the absolute values indicates the magnitude of variation between adjacent instantaneous values in FIG.

  Next, the processor 21 calculates L [1] as an average value of the absolute values | M [1] 1 | to | M [1] x |. This L [1] indicates the average magnitude of fluctuation in the power fluctuation time from when one instantaneous value is measured until the next instantaneous value is measured in the P time until the end time Te. L [1] according to the present embodiment indicates the magnitude of fluctuation in 10 seconds. The value of L [1] increases as the value of power supplied to the house H1 rises and falls violently at intervals of about 10 seconds. For this reason, the value of L [1] indicates the magnitude of periodic fluctuation with a period of 10 seconds of power fluctuation.

  Next, the processor 21 calculates L [2] by the same procedure after replacing the instantaneous values N [1] 1 to N [1] x with the average values N [2] 1 to N [2] x. To do. Specifically, the processor 21 calculates the series [3] by averaging two adjacent values in the series N [2]. Further, the processor 21 calculates a sequence M [2] from the sequences N [2] and N [3]. Then, the processor 21 calculates L [2] by averaging the absolute values of the differences constituting the series M [2].

  L [2] is the average magnitude of fluctuation in the power fluctuation time from the time when one instantaneous value is measured until the second instantaneous value is measured in the P time until the end time Te. Show. Therefore, L [2] according to the present embodiment indicates the magnitude of periodic fluctuation with a period of power fluctuation time of 20 seconds.

  Next, the processor 21 calculates L [3] to L [k] in the same manner as L [1] and L [2]. In FIG. 5, L [k] indicates the average magnitude of fluctuation from each instantaneous value to the k next instantaneous values, and the magnitude of periodic fluctuation with a period of k × 10 seconds. It will be shown. Note that the value of k is 18, for example, and is defined in advance.

  Returning to FIG. 4, the processor 21 changes the calculated L [1] to L [k] in combination with the end time Te and the like following the calculation of L [1] to L [k] (step S5). Stored as data 24d (step S6). Specifically, the processor 21 combines the L [1] to L [k] with the end time Te and the P time, and the power data 10d for the P time until the end time Te, to thereby add the second auxiliary storage unit. 24.

  Next, the processor 21 determines whether or not there is a request from the living behavior display device 30 (step S7). Specifically, the processor 21 determines whether or not the output of the fluctuation data 24d is requested. When it determines with there being no request | requirement (step S7; No), the processor 21 repeats the process after step S1. Thereby, the arithmetic unit 20 generates the fluctuation data 24d indicating the magnitude of the fluctuation in the past one hour at 0 minutes per hour.

  On the other hand, when it is determined that there is a request (step S7; Yes), the processor 21 determines whether there is variation data 24d for responding to the request (step S8). Specifically, the processor 21 determines whether or not the living behavior display device 30 has requested the output of the variation data 24 d already stored in the second auxiliary storage unit 24. When it is determined that there is the fluctuation data 24d (step S8; Yes), the processor 21 shifts the processing to step S11.

  On the other hand, when it is determined that there is no fluctuation data 24d (step S8; No), the processor 21 sets the end time Te and the value of the P time, and acquires the power data 10d (step S9). Specifically, the processor 21 acquires the power data 10d for P hours from the life activity display device 30 to the end time Te specified from the power meter 10 in the same procedure as steps S3 and S4.

  Next, the processor 21 calculates L [1] to L [k] and generates fluctuation data 24d (step S10). Specifically, the processor 21 calculates L [1] to L [k] by the same procedure as in step S5, and generates the fluctuation data 24d by the same procedure as in step S6. As a result, the processor 21 calculates the magnitude of the power fluctuation during the time designated by the daily activity display device 30.

  Next, the processor 21 responds to the living behavior display device 30 by transmitting the variation data 24d (step S11). Thereafter, the processor 21 repeats the processing after step S1. Thereby, the arithmetic unit 20 promptly transmits the fluctuation data 24d to the living behavior display device 30 in response to a request from the living behavior display device 30.

  Then, the display process performed by the lifestyle action display apparatus 30 is demonstrated using FIGS. The display process starts, for example, when a specific application is activated by an operation of the user U1. The process shown in FIG. 6 is basically executed by the processor 31 of the daily activity display device 30, but will be described below using the configuration of the functions shown in FIG. 2 as appropriate.

  As shown in FIG. 6, the processor 31 first displays an input screen (step S21). FIG. 7 shows an example of the input screen. In this input screen, parameters for the user U1 to draw desired information on the screen are input.

  As shown in FIG. 7, the input screen includes boxes 61 to 65 for specifying parameters related to the drawn time axis 41, a box 66 for specifying parameters related to the drawn image pattern 48, and input to the input screen. A button 67 for determining the contents entered, and a button 68 for canceling the contents entered on the input screen.

  Boxes 61 and 62 are used to specify the start date and time and the end date and time of the period indicated by the time axis 41. The box 63 is used for designating the number of folding steps of the time axis 41. A box 64 is used for designating a method for dividing the time axis 41. A box 65 is used for designating a time axis display method. A box 66 is used to specify the style of the image pattern 48.

  Returning to FIG. 6, following step S21, the processor 31 determines whether or not there is an input from the user U1 (step S22). Specifically, the processor 31 determines whether or not the user U1's finger touches the button 67 on the input screen. When it determines with there being no input from the user U1 (step S22; No), the processor 31 repeats the process after step S21. Thereby, the lifestyle action display apparatus 30 will wait for the input from the user U1.

  On the other hand, when it is determined that there is an input from the user U1 (step S22; Yes), the time axis setting unit 310 sets the time axis 41 on the screen 391 (step S23). Specifically, the time axis setting unit 310 sets one line on the screen 391 based on the number of folding stages specified in the box 63 and the display method specified in the box 65.

  For example, as shown in FIG. 7, when the number of folding stages of “6 stages” is specified, the time axis setting unit 310 ends from the upper left start point 42 to the lower right end as shown in FIG. 3. A time axis 41 extending to the point 43 is set. The time axis 41 extends horizontally from the start point 42 in the right direction, and when it reaches the right turn-around point 44 near the right end of the region 40, the time axis 41 turns back obliquely in the lower left direction. When the time axis 41 extending in the lower left direction reaches the left turning point 45 near the left end of the region 40, the time axis 41 is folded horizontally in the right direction. Then, the time axis 41 reaches the end point 43 after repeating the folding at the right folding point 44 and the left folding point 45. As a result, the time axis 41 in a state of being folded at the designated number of folding steps is set. However, the number of folding steps means the number of portions extending in the horizontal direction on the time axis 41.

  Further, as shown in FIG. 7, when the display method of “non-display at the time of folding” is designated, the time axis setting unit 310 is arranged horizontally on the time axis 41 as shown in FIG. The extending part is visible and the obliquely extending part is not visible. Thereby, only the visible part which extends in the horizontal direction on the time axis 41 is displayed substantially in parallel.

  Returning to FIG. 6, following step S23, the time axis setting unit 310 determines the correspondence between the time axis 41 and the time, and sets division points (step S24). Specifically, the time axis setting unit 310 associates the start point 42 of the time axis 41 with the start date and time specified in the box 61, and sets the end point 43 of the time axis 41 to the end specified in the box 62. Correspond to day and time. Then, the time axis setting unit 310 sets a division point for equally dividing the period corresponding to the start point 42 to the end point 43 by the division method specified in the box 64. Further, the time axis setting unit 310 assigns the date and time to the set division points.

  For example, when the start point 42 corresponds to 00:00 on January 1, 2013 and the end point 43 corresponds to 24:00:00 on the same day, a division method of “24 divisions (or every hour)” Is designated, each division point is assigned a time of 0 minutes per hour on the same day.

  However, when the display method of “non-display when folded” is specified in the box 65, the time axis setting unit 310 divides the time axis 41 except for an invisible part of the time axis 41. For example, when the parameters shown in FIG. 7 are input to the input screen, as shown in FIG. 3, only the visible portion extending horizontally in the time axis 41 is the target of division. As a result, the start point 42 and the dividing point that become the left turn point 45 are all assigned a time of 0: 0, and the dividing point and the end point 43 that become the right turn point 44 are both 24 hours 0. A time of minute is allocated. Accordingly, each visible horizontal line corresponds to one day from 0:00 to 24:00.

  Returning to FIG. 6, the time axis setting unit 310 displays a scale and the like following step S <b> 24 (step S <b> 25). For example, the time axis setting unit 310 displays a short scale that intersects the time axis 41 at each division point. Thereby, the position of the dividing point is specified. The time axis setting unit 310 may mark the time assigned to the dividing points on a scale. In addition, the time axis setting unit 310 may not display a scale at every division point. FIG. 3 shows an example in which scales are displayed at every other division point in the portion displayed at the bottom.

  In addition, the time axis setting unit 310 appropriately displays a character string that conveys an outline of the date and time assigned to the dividing point. For example, as illustrated in FIG. 3, when the period corresponding to the time axis 41 extends over a plurality of days, the time axis setting unit 310 displays “May 12” at a position corresponding to the time straddling the day. And so on. The time axis setting unit 310 displays a character string “today” at a position corresponding to the time when the day to which the current time belongs starts. The time axis setting unit 310 may display a time such as “1 o'clock” at a position corresponding to 0 minutes per hour, not limited to the date.

  Next, the processor 31 acquires the fluctuation data 24d for each divided period (step S26). Specifically, the processor 31 requests the arithmetic device 20 to output the fluctuation data 24d indicating the magnitude of fluctuation in each divided period, and obtains a response to the request. The division period is a period divided from a period corresponding to the time axis 41, and is a period from a date and time corresponding to one division point to a date and time corresponding to the next division point.

  For example, as shown in FIG. 3, when the division point is set to 0 minutes per hour, the processor 31 is requested to have the fluctuation data 24d for one hour whose end time is 0 minutes per hour. In this case, the arithmetic unit 20 outputs the fluctuation data 24d already stored in the second auxiliary storage unit 24.

  Next, the processor 31 executes pattern change processing (step S27). This pattern change process is executed in parallel with the display process. Hereinafter, the pattern change process will be described with reference to FIGS.

  As shown in FIG. 8, in the pattern change process, the pattern change unit 320 first activates the timer 36 (step S31).

  Next, the pattern changing unit 320 substitutes zero for the variable z (step S32). The value of the variable z represents the number of times that the regular timing is notified from the timer 36.

  Next, the pattern changing unit 320 calculates a reference attribute value (step S33). In the present embodiment, the pattern changing unit 320 calculates a center display magnification that is a reference for the dimensions of the image pattern 48 as a reference attribute value. Specifically, the pattern changing unit 320 calculates the absolute value of the ratio of the power value measured at the latest time in the period corresponding to the time axis 41 to the preset maximum power. However, the upper limit value of the center display magnification is defined as 1.0. Thereby, the reference attribute value (center display magnification) included in the range of 0.0 to 1.0 is calculated.

  For example, when the current time is included in a period corresponding to the time axis 41 and 3 kW is set as the maximum power, when the instantaneous value of the most recently measured power is 1.5 kW, the reference attribute The value is calculated as 0.5.

  Next, the pattern changing unit 320 arranges the image pattern 48 of the attribute based on the reference attribute value on each division point (step S34). As shown in FIG. 9, the pattern changing unit 320 according to the present embodiment reduces the image pattern 48 stored in the auxiliary storage unit 33 to a size multiplied by the center display magnification, and then on the dividing point. To place. For example, when the image pattern 48 stored in the auxiliary storage unit 33 is a 10-pixel square and the center display magnification is 0.5, the 5-pixel square image pattern 48 is arranged. Thereby, a plurality of image patterns 48 are displayed in a state of being superimposed on the time axis 41.

  The auxiliary storage unit 33 stores a square image circumscribing the circular icon as an image pattern 48. However, the transmittance other than the icon in this image is set to 100%. For this reason, the image pattern 48 is substantially equivalent to a circular icon.

  Next, the pattern changing unit 320 determines whether or not there is a notification from the timer 36 (step S35). When it is determined that there is no notification (step S35; No), the pattern changing unit 320 repeats the determination of step S35.

  On the other hand, when it is determined that there is a notification (step S35; Yes), the pattern changing unit 320 increments the variable z (step S36).

  Next, the pattern changing unit 320 selects the image pattern 48 (step S37). Specifically, the pattern changing unit 320 selects one image pattern 48 that has not been selected yet after the notification from the timer 36 in step S35.

  Next, the pattern changing unit 320 calculates the attribute value of the selected image pattern 48 (step S38). The pattern changing unit 320 according to the present embodiment calculates the display magnification using the following equation (1) as an attribute value for defining the dimension of the image pattern 48. However, S [z] in formula (1) represents the display magnification, and S [0] represents the center display magnification. Α is a coefficient set in advance. L [i] indicates the magnitude of fluctuation in the divided period including the time corresponding to the dividing point superimposed on the image pattern 48 as the end time.

  Next, the pattern changing unit 320 changes the attribute of the image pattern 48 based on the calculated attribute value (step S39). The pattern changing unit 320 according to the present embodiment reduces or enlarges the size of the image pattern 48 to a size multiplied by the calculated display magnification. For example, when the display magnification is calculated as 0.8, an 8-pixel square image pattern 48 is displayed. The upper limit value of the display magnification is defined as 1.0.

  Next, the pattern changing unit 320 determines whether there is an unselected image pattern 48 (step S40). When it is determined that there is an unselected image pattern 48 (step S40; Yes), the pattern changing unit 320 repeats the processing after step S37. As a result, the image patterns 48 displayed on the screen 391 are sequentially selected and their attributes are changed.

  On the other hand, when it is determined that there is no unselected image pattern 48 (step S40; No), the pattern changing unit 320 repeats the processing after step S35. Thus, as shown in FIG. 9, every time the timing is notified from the timer 36, the attributes of all the image patterns 48 are changed.

  Returning to FIG. 6, following step S27, the no-reaction time presentation unit 330 detects the no-reaction time (step S28). Specifically, the no-reaction time presentation unit 330 identifies the latest divided period among the periods corresponding to the time axis 41, and indicates the magnitude of the fluctuation in the divided period from L [1] to L [k]. Calculate the sum. The non-reaction time presentation unit 330 determines that the non-reaction time is zero when this sum exceeds a predetermined threshold.

  On the other hand, when this sum is less than or equal to the threshold value, the no-reaction time presentation unit 330 attempts the same determination for the immediately preceding divided period. When the sum of L [1] to L [k] for the immediately preceding divided period exceeds the threshold, the no-reaction time presentation unit 330 determines that the no-reaction time is a time corresponding to one divided period (1 hour). . On the other hand, for the immediately preceding divided period, when the sum of L [1] to L [k] is equal to or less than the threshold value, the non-response time presenting unit 330 repeats the same determination back to the previous divided period. Thereby, the no-reaction time presentation unit 330 detects the time during which the state where the sum of L [1] to L [k] is equal to or less than the threshold continues as the no-reaction time.

  Next, the no-reaction time presentation unit 330 presents the no-reaction time (step S29). For example, when the no-response time is 3 hours, the no-response time presentation unit 330 displays the message shown in FIG.

  However, the no-response time presentation unit 330 changes the size of the message displayed in the region 50 according to the no-response time, as shown in FIG. Thereby, a message with a larger size is displayed as the non-response time is longer. The correspondence between the length of the no-response time and the message size is set in advance.

  Thereafter, the processor 31 ends the display process.

  As described above, the living behavior display device 30 according to the present embodiment displays the animation of the image pattern 48 by changing the attribute. This display method is greatly different from the conventional display method using a static graph such as a bar graph or a line graph. In the display method according to the present embodiment, the magnitude and period of fluctuation of the power supplied to the house H1 are expressed as the amplitude and period of vibration of the image pattern 48.

  Specifically, the living activity display device 30 changes the attribute of the image pattern 48 displayed for each divided period according to the equation (1). As shown in Expression (1), the attribute value of the image pattern 48 is associated with L [1] to L [k] and periodically changes by a sine function. As can be seen from Equation (1), the period of this change is determined according to the length of the power fluctuation time corresponding to each of L [1] to L [k].

  For example, when only the value of L [1] is remarkably large and the values of L [2] to L [k] are almost zero, the attribute of the image pattern 48 vibrates little by little. That is, the image pattern 48 repeats enlargement and reduction alternately in a short cycle. Further, when the values of L [1] to L [k−1] are almost zero and only the value of L [k] is remarkably large, the attribute of the image pattern 48 vibrates slowly. That is, the image pattern 48 repeats enlargement / reduction in a long cycle. Further, when the values of L [1] and L [k] are remarkably large and the values of L [2] to L [k−1] are almost zero, the attribute of the image pattern 48 is small vibration and Changes with slow vibrations simultaneously.

  Thereby, the user U1 can recognize the magnitude of the periodic fluctuation in each divided period approximately every period by visually recognizing the change in the attribute of the image pattern 48.

  The electric power consumed by the electrical equipment due to the living behavior of the residents varies in various forms. That is, the electric power supplied to the house H1 by living behavior fluctuates in various cycles, and this cycle does not take a fixed value. On the other hand, it is known that the electric power consumed by an electric device that is automatically operated regardless of daily activities fluctuates at a relatively long fixed period.

  In other words, the electric power supplied to the house H1 when there is a living activity varies in small increments, while the electric power when there is no living activity does not vary in small increments. For this reason, the user U1 can intuitively determine the presence / absence of living behavior in each divided period only by looking at whether or not the attribute of the image pattern 48 is changing in small increments. As a result, it is possible to intuitively grasp the resident's state without forcing the user U1 to perform special work.

  In addition, the living behavior display device 30 according to the present embodiment sets the time axis 41 according to the start date / time, end date / time, number of folding steps, division method, and display method specified by the user U1. Thereby, the lifestyle action display device 30 can easily display information with high visibility according to the use of the user U1 on the screen 391.

  For example, the living behavior display device 30 displays the time axis 41 by folding it. For this reason, the living behavior display device 30 can display high-density information on the screen 391 even when the period corresponding to the time axis 41 is relatively long. Accordingly, the user U1 can easily grasp the divided period in which the power fluctuation indicated by the image pattern 48 has occurred. Further, the user U1 can easily compare the power fluctuation in this divided period with the power fluctuation in the divided periods before and after this divided period and the divided periods displayed in the upper and lower stages.

  Specifically, the user U1 can compare power fluctuations in the same time zone over a plurality of days by viewing the screen 391 in order from top to bottom. In the example shown in FIG. 3, when the user U1 wants to check the status of the resident in the time zone from 8 am to 9 am from May 10 to May 15, 9:00 am on May 10 It is only necessary to move the line of sight directly from the corresponding position.

  In addition, on the input screen (see FIG. 7) according to the present embodiment, it is possible to specify a division method. For this reason, the user U1 can easily compare the fluctuations in power for each week by designating the parameters so that one week is displayed in one row.

  Moreover, the living action display device 30 according to the present embodiment presented a no-reaction time. Thereby, user U1 can recognize easily the time when the fluctuation | variation of the electric power as a reaction with respect to a living activity is not detected. For example, when the user U1 observes the image pattern 48 displayed for hundreds of divided periods, the user U1 can quickly detect the danger without missing the abnormal state of the resident.

Embodiment 2. FIG.
Next, the second embodiment will be described focusing on the differences from the first embodiment. In addition, about the structure which is the same as that of the said Embodiment 1, or equivalent, while using an equivalent code | symbol, the description is abbreviate | omitted or simplified.

  The living behavior display device 30 according to the present embodiment is different from that according to the first embodiment in that a waveform is displayed as the image pattern 48. The image pattern 48 is different from that according to the first embodiment in that the dimension of only the vertical direction (direction perpendicular to the time axis 41) is changed as an attribute.

  FIG. 11 shows an example of a screen 391 on which a waveform is displayed as the image pattern 48. The image pattern 48 is displayed when the user U1 designates a display method of “waveform display” in the box 66 (see FIG. 7) of the input screen.

  In step S33 (see FIG. 8), the pattern changing unit 320 according to the present embodiment supports a triangular waveform vector having a width of 1 to k and the same height as shown in FIG. Read from the storage unit 33. The pattern changing unit 320 may read a triangular wave waveform vector having a period of 1 to K. Each dimension of the waveform vector is k-dimensional. The pattern changing unit 320 obtains a waveform vector W by multiplying these waveform vectors by L [i] and adding them using the following equation (2). However, T [i] in Equation (2) represents a waveform vector having a width i.

  The pattern changing unit 320 determines the shape of the image pattern 48 based on the calculated waveform vector W. Then, the pattern changing unit 320 defines the size of the image pattern 48 displayed on the screen 391 in the direction perpendicular to the time axis 41 according to the calculated reference attribute value (center display magnification). The pattern changing unit 320 defines the dimension of the image pattern 48 in the direction parallel to the time axis 41 according to the distance between the division point and the adjacent division point.

  As described above, the living activity display device 30 according to the present embodiment adds the waveforms obtained by multiplying each of the triangular waves having a width of 1 to K by L [1] to L [k], An image pattern 48 is assumed. For this reason, the shape of the image pattern 48 corresponds to the cycle and magnitude of the power fluctuation.

  For example, when only the value of L [1] is remarkably large, the image pattern 48 has a waveform that vibrates in small increments. Further, when only the value of L [k] is remarkably large, the image pattern 48 has a waveform that vibrates slowly. Thereby, the user U1 can recognize the magnitude of the periodic power fluctuation in each divided period approximately every period by visually recognizing the shape of the image pattern 48.

  As mentioned above, although embodiment of this invention was described, this invention is not limited by the said embodiment.

  For example, the time axis 41 according to the above embodiment is displayed in a folded state, but may be displayed as one straight line that is not folded, as shown in FIG.

  Moreover, although the time axis 41 according to the above embodiment is configured from a straight line, it may be configured including a curve. In addition, a visible part and an invisible part of the time axis 41 may be arbitrarily set. The visually recognizable part may be displayed with a solid line or may be configured to include a dotted line.

  In the above embodiment, the time axis is defined by the line from the start point 42 to the end point 43, but the present invention is not limited to this. For example, an annular line may be set as the time axis 41 as shown in FIG. Further, as shown in FIG. 14, the image patterns 48 may overlap each other. Instead of the scale of the time axis 41, a character string indicating the date and time may be attached in the vicinity of the image pattern 48 or on the image pattern 48.

  In the input screen according to the above embodiment, parameters are specified in boxes 61 to 66 by the user U1. When this input screen is first displayed, a preset parameter may be set as an initial value in the boxes 61 to 66 regardless of whether or not there is an input from the user U1. When an appropriate initial value is set, the user U1 can obtain desired information simply by touching the button 67.

  As shown in FIG. 15, a button 69 for inputting a preset parameter group in boxes 61 to 66 may be displayed on the input screen. The button 69 is a button for displaying information based on a data set of “today's data”, for example. When the user U1 touches the button 69, 0:00 of the day to which the current time belongs is specified in the box 61 as the start date and time, and 24:00:00 of the day to which the current time belongs is set in the box 62 as the end date and time. It is specified. Further, the number of folding stages of “1 stage” is designated in the box 63, and the display method of “straight line display” is designated in the box 65. The example shown in FIG. 13 is displayed when these parameter groups are designated.

  Further, for example, when the user U1 touches a button that displays information based on the data set “this week's data”, 00:00 of Sunday of the week to which the current time belongs is designated as the start date and time, and this Saturday of the week. 24:00:00 may be designated as the end date and time. Furthermore, the number of folding stages of “7 stages” and a display method of “non-display when folded” may be designated.

  Moreover, the lifestyle action display apparatus 30 may expand a pull-down menu from each of the boxes 61 to 66, and acquire a candidate selected by the user U1 as a designated parameter. Moreover, the lifestyle action display apparatus 30 may display the boxes 61 to 66 as a text input field, and may acquire the text input by the user U1 as a designated parameter.

  Moreover, although the size is changed as the attribute of the image pattern 48 in the living behavior display device 30 according to the above embodiment, the shape, color, angle, and pattern of the image pattern 48 may be changed.

  For example, as illustrated in FIG. 16, a waveform having an amplitude corresponding to L [1] to L [k] may be generated as an image pattern 48 based on the variation data 24d stored in the auxiliary storage unit 33. Good. Then, instead of the display magnification according to the above embodiment, as shown in FIG. 16, the shape (attribute) of the image pattern 48 may be changed by changing the phase of the waveform.

  In addition, as shown in FIG. 17, based on the variation data 24 d, a figure filled with a hue color corresponding to L [1] to L [k] may be generated as the image pattern 48. Then, instead of the display magnification according to the above embodiment, as shown in FIG. 17, the attribute of the image pattern 48 may be changed by changing the brightness of the figure.

  Further, as shown in FIG. 18, an icon indicating a fan having a shape and size corresponding to L [1] to L [k] may be generated as an image pattern 48 based on the variation data 24d. Then, instead of the display magnification according to the above embodiment, as shown in FIG. 18, the attribute of the image pattern 48 may be changed by changing the angle of the fan.

  In addition, as shown in FIG. 19, a pattern icon corresponding to L [1] to L [k] may be displayed as an image pattern 48 based on the variation data 24d. Then, instead of the display magnification according to the above embodiment, as shown in FIG. 19, the attribute of the image pattern 48 may be changed by changing the pattern.

  Further, the living behavior display device 30 may not change the attribute of the image pattern 48 based on all of L [1] to L [k] included in the variation data 24d. For example, the attribute of the image pattern 48 may be changed using only two of L [1] to L [k] having a large value. When only a part of L [1] to L [k] is used, the characteristics of power fluctuation are emphasized and the attribute of the image pattern 48 changes, so that the user U1 can more intuitively change the power. Can be recognized.

  Further, the calculation by the calculation device 20 is not limited to the above embodiment. For example, the arithmetic unit 20 may perform the Fourier transform on the transition of the power value in the divided period, and set the power of the frequency component to L [1] to L [k] in the order of the shortest period.

  Moreover, although the electric power fluctuation time which concerns on the said embodiment was prescribed | regulated by making the period of the measurement by the electric power measuring device 10 into unit time, it is not limited to this. For example, the living behavior display device 30 designates the power fluctuation time corresponding to each of L [1] to L [k] to the computing device 20, and the computing device 20 performs L based on the designated power fluctuation time. [1] to L [k] may be calculated.

  Moreover, although the living action display system 100 according to the above-described embodiment includes the power meter 10, the arithmetic device 20, and the living action display apparatus 30, the present invention is not limited to this. For example, the living behavior display device 30 may exhibit the function of the arithmetic device 20. Further, the power meter 10 may exhibit the function of the arithmetic device 20. Moreover, you may implement | achieve the lifestyle action display system 100 with one apparatus.

  The functions of the computing device 20 and the daily activity display device 30 according to the above-described embodiment can be realized by dedicated hardware or by a normal computer system.

  For example, the programs P2 and P3 stored in the first auxiliary storage unit 23 and the auxiliary storage unit 33 can be read by a computer such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), and a DVD (Digital Versatile Disk). By storing and distributing in a recording medium and installing the programs P2 and P3 in a computer, an apparatus for executing the above-described processing can be configured.

  Further, the programs P2 and P3 may be stored in a disk device or the like included in a predetermined server device on a communication network such as the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example.

  The above-described processing can also be achieved by starting and executing the programs P2 and P3 via the communication network.

  Furthermore, the above-described processing can also be achieved by executing all or part of the programs P2 and P3 on the server device and executing the programs P2 and P3 while the computer transmits and receives information related to the processing via the communication network. can do.
