  In general, in order to know the detailed power consumption status in consideration of the operating status of each device, a large number of measuring devices (for example, power meters) are required. Furthermore, in a building such as a building, a large number of air conditioners, lighting devices, and the like as control objects are arranged, and there are cases where a plurality of tenants are usually occupying each floor. For example, in order to know the power consumption status of air conditioning, lighting, etc. for each distribution system such as a room, floor, department, etc., it is necessary to install a power meter or the like at least for each distribution system. Therefore, there is a problem that a lot of cost is required for system construction. In addition, even if a power meter or the like is installed as an existing facility, it is rare that a measuring device is provided for each distribution system such as a department. Check the power consumption status for each distribution system to be measured. There is a problem that cannot be done.

  Also, for example, a BEMS (Building and Energy Management System) is used to provide a power meter or the like for each distribution system to be measured, collect the measurement results, and perform prediction calculation processing of power consumption transitions. It is necessary to additionally install a set of devices for performing expensive processing and control (for example, a new centralized control device, arithmetic device, display device, etc.), and there is a problem that it is expensive.

  Furthermore, when using a watt-hour meter or the like to display the power consumption status, it takes time until the actual change in the power consumption is confirmed after changing the operation settings for each load such as air conditioning and lighting. . Therefore, there is also a problem that it is difficult to display the power consumption status in real time with good response. Further, if there is a time lag in the display of the power consumption status, it is difficult to confirm how much energy saving is effective by changing the setting in each device, and there is a problem that it is difficult for the user to take root in energy saving.

  Incidentally, looking at the invention described in Patent Document 1, there is a description of a mode in which one device adapter is installed on a distribution board as a power supply window (see Patent Document 1: Claim 3). However, the power consumption status cannot be confirmed for each room or system only by installing the device adapter on the distribution board, particularly in a building. Actually, in order to grasp the detailed power consumption state, a form installed for each electric device is also shown (see Patent Document 1: FIG. 1 and the like). Therefore, when the invention described in Patent Document 1 is applied to building management, a large amount of equipment adapters are required, and the problem that a lot of cost is required for system construction cannot be solved. Further, since the invention described in Patent Document 1 acquires information on the power consumption from a device adapter every predetermined time (for example, one hour) (see Patent Document 1: Paragraph [0007] etc.), A certain power consumption status cannot be displayed.

  The present invention has been made in view of the above-described problems of the prior art, and can display a low-cost and real-time power consumption state without installing numerous measuring devices such as watt-hour meters and adding devices. The task is to do.

It was and.

  According to this configuration, the estimated value of the power consumption of the distribution system is calculated from the operation status such as ON / OFF of each device instead of the actual measurement result. No measuring equipment is required. In addition, since the programmable display accepts settings and inputs related to device operation, calculation and display regarding the power consumption status can be realized with a single programmable display, and expensive equipment such as BEMS, rooms, floors, departments, lighting In addition, it is not necessary to add measuring equipment for each distribution system of air conditioning and air conditioning, and the configuration required for checking the power consumption status can be reduced. Furthermore, in the actual power consumption measurement, it took a certain amount of time for the result of the device setting change to appear as a measurement result, and there was a time delay until the result was reflected in the power consumption status. The setting change is reflected in the power consumption status image in real time. Therefore, the user can immediately recognize the energy saving effect and waste at the time of operation, and can aim at thorough awareness of energy saving to the user.

And the programmable display of this invention calculates the estimated value of power consumption for every power distribution system, and displays a power consumption condition display. Further, in this specification, the term “image” includes not only so-called images and pictures but also all data that can be displayed on a display screen, such as text files. The power consumption status image is realized by, for example, numerical values, characters, patterns, figures, and the number of displayed figures, color coding, and the like, and it is only necessary to be able to transmit the amount of power currently consumed to the user.

The power consumption status image is displayed.

  According to this configuration, for example, each device can be allocated to an arbitrary power distribution system such as a floor, a department, a room, and the power consumption status of each power distribution system can be confirmed. In addition, it is possible to flexibly cope with a layout change on the floor, etc., and it is possible to display the power consumption status without requiring an operation such as changing the installation position of the watt hour meter or the like.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the data memory is a value for comparing the power consumption estimated value and setting a power consumption determined for each distribution system. The power setting value is also stored, and the arithmetic unit compares the power consumption estimated value of the distribution system with the power consumption setting value, and the power consumption estimated value exceeds the power consumption setting value. The warning image is displayed on the display screen.

  According to this configuration, it is possible to make the user recognize that power is consumed excessively. Therefore, thorough awareness of energy saving to the user can be achieved. The power consumption setting value is a value for displaying a warning that power is consumed excessively when the power consumption estimation value exceeds the power consumption setting value. The power consumption data and the number of devices included in the power distribution system It can be arbitrarily determined in consideration of the type of device and the operating status of the device.

That is, the lighting device keys P8 to P16 function as a switch for turning on / off, and the display is switched depending on the lighting / lighting state.

  Further, above the lighting device keys P8 to P16, in order to perform overall lighting on / off control in the room, as the component image P, for example, the lighting batch ON key P17, the lighting thinning lighting key P18, and the lighting batch An OFF key P19 and the like are arranged. If the illumination batch ON key P17 is pressed, all the illumination devices 5 in the room are turned on. If the illumination thinning key is pressed, a part of the room (for example, about half, four, or five) is turned on to save power. If the illumination batch OFF key P19 is pressed, all the lighting devices 5 in the room are turned off. In this way, the user can perform lighting on / off control by pressing the display screen 11 of the programmable display 1. If the dimming illumination device 5 is attached, the intensity of light may be set.

(Air conditioning control)
Next, an example of air conditioning control will be described based on FIG. FIG. 5 is an explanatory diagram illustrating an example of a display for air conditioning control on the programmable display 1 according to the embodiment of the present invention. In this description, a room R1 with a personnel department or the like is selected, and each department has one or two indoor unit types (for example, a ceiling-mounted air conditioner, a total of five). An example will be described.

  As shown in FIG. 5A, when a room is selected and the air conditioning key P3 is pressed, an air conditioning equipment key P20 as a component image P showing each air conditioning equipment 6 assigned to each department is displayed on the display screen 11. -P24 is displayed. The user can set the operation of each air conditioner 6 by pressing each air conditioner key P20 to P24. In each of the air conditioner keys P20 to P24, for example, the characters “operating” and “stopped” are displayed to indicate the operation status of the air conditioner 6.

  And as shown in FIG.5 (b), when the air-conditioning equipment keys P20-P24 are pushed, the air-conditioning setting panel P25 is displayed on the display screen 11 as the component image P. FIG. Further, in the air conditioning setting panel P25, as an input key (part image P), there are an operation key P26 and a stop key P27 for instructing operation and stop of the air conditioner 6, and a cooling key P28 for instructing an operation type. A heating key P29, an upper key P30, a lower key P31 for raising and lowering a set temperature desired by the user, a strong wind key P32, a weak wind key P33, and a light wind key P34 for setting the air volume are arranged. Note that the key selected by pressing is highlighted (in FIG. 5 (b), a black character key is shown as a selected key). The user can set the operation of each air conditioner 6 by pressing each key in the air conditioning setting panel P25. That is, the air conditioner keys P20 to P24 function as call keys for the air conditioning setting panel P25 such as temperature and air volume, and the display is switched depending on the operation and stop status.

  Above the air conditioner keys P20 to P24, in order to perform overall operation control of the air conditioner 6, as the part image P, for example, an air conditioner collective ON key P35, an air conditioner thinning operation key P36, an air conditioner collective OFF key P37 etc. are arranged. If the air-conditioning collective ON key P35 is pressed, all the air-conditioning devices 6 are in operation. For example, when the air-conditioning thinning key is pressed for ventilation or the like, a part of the room (for example, two or three) becomes an operating state, and power is saved. If the air conditioning batch OFF key P37 is pressed, all the air conditioning devices 6 in the room are stopped. In this way, the user can control the air conditioner 6 by pressing the display screen 11 of the programmable display 1.

(Calculation of estimated power consumption)
Next, based on FIG. 6, calculation of the estimated value of the power consumption for every power distribution system, such as a department, a room, a floor, etc. which concerns on embodiment of this invention is demonstrated. FIG. 6 is a diagram showing a table as an example of power consumption data when calculating an estimated value of power consumption for each distribution system according to the embodiment of the present invention. In FIG. 6, since it may vary depending on the model of the lighting device 5 or the air conditioning device 6, it is shown as A, B1, B2, Xa to Xc, Ya, Yb, Za, Zb. Numerical value.

  In the present invention, for example, an estimated value of the current power consumption of a device arranged for each power distribution system such as a department such as the human resources department or the accounting department, floor, or room unit is calculated, and power distribution is performed based on the obtained estimated value. Displays the power consumption status of the grid. Therefore, one power distribution system basically includes a plurality of devices such as the lighting equipment 5 and the air conditioning equipment 6.

  Then, first, the setting of the power distribution system in the programmable display 1 which concerns on embodiment of this invention is demonstrated. Which distribution system each lighting device 5 and each air conditioning device 6 belongs to can be set using the image data creation program 27 of the host computer 2. For example, since an address is assigned to each lighting device 5 and each air conditioning device 6 for control purposes, which lighting system 5 or each air conditioning device 6 belongs to which distribution system, such as the personnel department or the room R1, based on the address? It may be settable. Then, the programmable display 1 receives data in which each lighting device 5 or each air conditioning device 6 belongs to which power distribution system from the host computer 2 via the I / F unit 13 and stores it in the data memory 15. Remember.

  The image data creation program 27 creates a setting screen for setting which distribution system each lighting device 5 and each air-conditioning device 6 belongs to, and displays it on the display screen 11. It may be possible to determine which distribution system each lighting device 5 and each air conditioning device 6 belongs to. In this way, the user can arbitrarily set which distribution system each lighting device 5 and each air conditioning device 6 belongs to. Therefore, even if there is a layout change in the room, or the addition or removal of the lighting device 5 or the air conditioning device 6, it can be flexibly dealt with. In the distribution system setting, for example, for one device, the distribution system is arranged in a tree structure such as “user name (whole)” → “floor name” → “room” → “department name” → “section name”. May be set. Thereby, even when a user occupies a plurality of floors (a plurality of floors) in a building, each device can be provided with a plurality of types of power distribution systems, such as the whole, each floor, each room, and each department.

  Next, calculation of an estimated value of power consumption for each distribution system will be described. Calculation of the estimated value of power consumption for each distribution system is performed using power consumption data (table) as shown in FIG. 6, for example. The power consumption data is stored in, for example, the data memory 15 of the programmable display device 1. The table shown in FIG. 6B is shared for heating and cooling. However, a table for heating and cooling may be prepared, and a difference may be given depending on heating and cooling.

First, the power consumption of each lighting device 5 can be determined based on the power consumption data as shown in FIG. 6A, for example, by whether each lighting device 5 is turned on or off. If the lighting device 5 is in the lighting state, the power consumption of the lighting device 5 is determined as A. Here, A can be arbitrarily determined, and A may be the value of the actual rated power consumption of the lighting device 5, or the actual rated power consumption of the lighting device 5 under a certain standard. A number replaced with another value (in other words, a value as an index of power consumption) may be used (the same applies to B1, B2, Xa to Xc, Ya, Yb, Za, and Zb in FIG. 6B). In addition, if there are two or more types of lighting devices 5 controlled by the programmable display device 1, a plurality of types of power consumption data relating to lighting may be provided. Therefore, the estimated value of the power consumed for using the lighting device 5 in the distribution system is expressed by the following equation.
(Equation 1) Power consumption (estimated value) of lighting device 5 W0 = A × number of lighting units

Next, the estimated value of the power consumption of each air conditioner 6 is obtained from the operation status of each air conditioner 6 based on the power consumption data as shown in FIG. First, the fixed number of loads shown in FIG. 6B corresponds to the power consumed by the outdoor unit, in other words, the power consumed if even one air conditioner 6 corresponding to the indoor unit is operating. And the value of the power consumption as a number fixed load becomes B1 in FIG.6 (b). In addition, when the outdoor unit is shared with the distribution system of other departments, for example, it can be equally allocated with the distribution system of the same rank. Therefore, the power consumption in the air conditioner 6 corresponding to the outdoor unit in one power distribution system such as a department is expressed by the following equation.
(Formula 2) Power consumption of outdoor unit (estimated value) W1 = B1 / number of shared power distribution systems

Next, the number-variable load shown in FIG. 6B corresponds to the power consumption per unit of the air conditioner 6 corresponding to the operating indoor unit, and is represented as B2 per unit. Therefore, the basic power consumption in the air conditioner 6 corresponding to the indoor unit in one power distribution system such as a department is expressed by the following equation.
(Formula 3) Basic power consumption (estimated value) of indoor units W2 = B2 × number of units in operation

  Next, the setting fluctuation load shown in FIG. 6B is a value determined in consideration of the change in power consumption due to the setting of the air conditioner 6. In addition, although the setting content of the air conditioner 6 may affect the power consumption of both the outdoor unit and the indoor unit, here, the setting variable load is set for each indoor unit without considering the distinction between the outdoor unit and the indoor unit. think of.

  First, the setting fluctuation load 1 takes into consideration that the power consumed increases as the amount of wind blown from the indoor unit increases. Each value Xa, Xb, Xc indicating each power consumption is determined according to the air volume. For example, a relationship of Xa> Xb> Xc can be given.

  And with the setting fluctuation load 2, the air conditioner 6 generally consumes electric power and fills the temperature difference as the difference between the temperature set by the programmable display 1 and the temperature measured by the indoor unit increases. This is because the power consumed increases as the temperature difference increases. Therefore, each value of Ya and Yb indicating each power consumption is determined according to the temperature difference. For example, a relationship of Ya <Yb can be given. The indoor temperature can be measured using a temperature sensor provided in the air conditioner 6 corresponding to the indoor unit.

  Furthermore, the setting variable load 3 generally takes into account that the efficiency of the air conditioner 6 may change depending on the difference between the room temperature and the outside temperature (for example, the greater the temperature difference, the more power is consumed). Is. Therefore, the values of the coefficients Za and Zb related to the power consumption are determined according to the temperature difference. For example, a relationship of Za <Zb can be given. The outside air temperature can be detected by using a temperature sensor provided in the air conditioner 6 corresponding to the outdoor unit.

Therefore, using the above Xa to Xc, Ya, Yb, Za, Zb, the power consumption per unit of the air conditioner 6 corresponding to the indoor unit that varies according to the setting of the air conditioner 6 corresponding to the indoor unit is Is represented by the following equation. Here, in Expression 4, the corresponding value among Xa to Xc is X, Ya, Yb, the corresponding value is Y, Za, Zb, and the corresponding coefficient is Z.
(Expression 4) Setting fluctuation power consumption (estimated value) W3 = X + (Y × Z)
Further, the temperature and air volume setting of each air conditioner 6 corresponding to the indoor unit in the present embodiment can be made different, and the power consumption differs depending on the setting. Therefore, the air conditioner 6 in the power distribution system such as a department. The sum is taken for each of the units, and the value of this sum is set as W31.
Then, the estimated value of the power consumption in the power distribution system such as a department is obtained by the following formula.
(Expression 5) Power consumption (estimated value) W = W0 + W1 + W2 + W31

(Display control of power consumption status image 3)
Next, based on FIG. 7, an example of display control of the power consumption status image 3 (see FIG. 8A) on the programmable display 1 according to the embodiment of the present invention will be described. FIG. 7 is a flowchart showing an example of control when displaying the power consumption status image 3 according to the embodiment of the present invention.

  The display control of the power consumption status image 3 may be performed at a constant cycle (for example, every several seconds to several tens of seconds). However, when the user turns on / off the lighting device 5 or sets the operation of the air conditioning device 6. Since the power consumption always fluctuates, the display control of the power consumption status image 3 will be described below when the user performs setting and operation of the lighting device 5 and the air conditioning device 6 on the programmable display 1. To do. In addition, the device as a control target and / or the control device 4 that controls the device and the programmable display 1 are in a communicable state.

  First, a component image P for instructing device operation is displayed on the display screen 11 of the programmable display 1 (step # 1). Next, the touch panel 12 receives an input by pressing the component image P (step # 2). Next, the HMI control unit 10 is connected to the control device 4 and also grasps the lighting / light-off state of each lighting device 5 that is directly connected to the programmable display 1, that is, each lighting device 5 that the programmable display 1 has jurisdiction over. (Step # 3). Further, the HMI control unit 10 is connected to the control device 4 such as the operating state or the stopped state, the set temperature, the room temperature, the outside air temperature, the strength of the air volume, etc., or directly connected to the programmable display 1. That is, the operating status of each air conditioner 6 that the programmable display 1 has jurisdiction is ascertained (step # 4).

  Thereafter, the power consumption data indicating the power consumption of the device is referred to according to the operation status of the device stored in the data memory 15 of the programmable display 1 (step # 5). Then, as described with reference to FIG. 6, the HMI control unit 10 is caused to perform an operation for estimating the power consumption for each distribution system, which is a combination of a plurality of devices under control, based on the power consumption data (step # 6). The HMI control unit 10 determines the power consumption status image 3 to be displayed as the component image P for each distribution system such as a department based on the obtained estimated value (step # 7), and the calculated estimated power consumption value Is displayed on the display screen 11 (see FIG. 8B, step # 8 → end). That is, the display screen 11 of the programmable display 1 of the present embodiment displays the power consumption status image 3 that changes depending on the magnitude of the estimated value.

(Determination of power consumption status image 3)
Next, based on FIG.8 and FIG.9, an example of the power consumption condition image 3 displayed on the display screen 11 which concerns on embodiment of this invention, and its determination is demonstrated. FIG. 8 is a schematic diagram showing an example of the power consumption status image 3 according to the embodiment of the present invention. FIG. 9 is an explanatory diagram showing an example of data for determining the power consumption status image 3 displayed on the display screen 11 according to the embodiment of the present invention.

  First, Fig.8 (a) has shown an example of the power consumption condition image 3 in each electric system changed in steps according to a power consumption condition. FIG. 8A shows an example using a face figure. As shown in FIG. 8 (a), the power consumption status image 3 in this embodiment is divided into four levels (for convenience, each level is superior depending on the magnitude of the estimated power consumption in the distribution system. In the example shown in FIG. 8A, the calculated value on the right side is smaller, and the energy on the right side is better (higher) in the example shown in FIG. 8A. Become.

  FIG. 8B is an example of display on the display screen 11 when the power consumption status image 3 is displayed (step # 8 in FIG. 7). As shown in FIG. 8B, the power consumption status image 3 can be displayed for each department. Further, it is possible to display the power consumption status image 3 by treating a combination of a plurality of departments for each room (room R1, room R2), or treating the whole of the room R1 and room R2 as one power distribution system. .

  Next, how to determine the power consumption status image 3 to be displayed with respect to the calculated estimated power consumption in the distribution system (step # 7 in FIG. 7) will be described with reference to FIG. As shown in FIG. 9, each distribution system is provided with a set value (illustrated as T1 to T9 in FIG. 9) to be compared with a predetermined estimated power consumption value of each distribution system. In each power distribution system, the number of lighting devices 5 and air conditioners 6 to be installed, and the model, etc. may be different. Therefore, the set value can be arbitrarily determined, and the set value may be different depending on each power distribution system.

  Each distribution system is provided with a threshold value for determining which power consumption status image 3 is displayed within a range of values smaller than the set value (threshold values are shown as TH1 to TH18 in FIG. 9). The threshold value can be arbitrarily determined. For example, in the example shown in FIG. 9, in the public relations section, the threshold value TH1 is set to 1/3 of the set value T1, and the threshold value TH2 is set to 2/3 of the set value T1. It is good also as the value of. Then, if the estimated value falls within the value of 0 to approximately 33% of the set value, the “excellent” power consumption status image 3a is selected. If the estimated value falls within the range of about 33% to about 67% of the set value, the “good” power consumption situation image 3b is selected. If the estimated value falls within about 67% of the set value to the set value, the “permitted” power consumption status image 3c is selected. If the estimated value exceeds the set value, it can be clearly determined that the power consumption state is excessive, so the power consumption state image 3d of “impossible” is selected.

  Here, the setting value will be described. There are various ways of determining the set value, and it can be arbitrarily determined. For example, in one distribution system, the temperature setting of the air conditioner 6 is set to the recommended cooling temperature (for example, 28 ° C.) in Cool Biz or heating in Warm Biz. The recommended temperature (for example, 17 ° C.) is set, and the outside air temperature is assumed to be the daytime average temperature in summer or the daytime average temperature in winter, and the lighting device 5 is all turned on. For that situation, the HMI control unit 10 is caused to calculate an estimated value. If this estimated value or the value obtained with a certain margin is determined as the set value in the distribution system, the power consumption status can be displayed based on Cool Biz and Warm Biz. it can. Further, in one power distribution system, the lighting device 5 may be turned on as much as the user prefers, and an estimated value obtained when the user operates at the set temperature of the air conditioning device 6 may be used as the set value in the power distribution system. In addition, if there is an in-house utility cost reduction target (for example, 10% reduction, etc.), if 90% of the current set value is set as a new set value, a guideline for achieving the target for reducing energy cost It can be. That is, the set value can be set as a guideline that should not be exceeded in terms of power consumption.

  Further, as shown in FIG. 8B, a message column P40 can be provided in the display of the power consumption status image 3. In the message column P40, a warning display indicating that power is excessively consumed is displayed for the distribution system in which the calculated power consumption estimated value exceeds the power consumption setting value. For example, as shown in FIG. 9, a warning message including a department name such as “The public relations department uses too much electricity” is displayed.

  That is, the programmable display device 1 of the present embodiment can set which distribution system the device as a control target belongs to by input to the touch panel 12 or data transmission to the I / F unit 14. The HMI control unit 10 performs a calculation for estimating the power consumption for each power distribution system, and the display screen 11 displays the power consumption status image 3 for each power distribution system. Further, the data memory 15 compares the power consumption estimated value, and also stores a power consumption setting value determined for each power distribution system for confirming whether power is consumed excessively. The HMI control unit 10 The power consumption estimated value of the power distribution system is compared with the power consumption set value, and the display screen 11 is recognized as a result of the comparison that the power consumption estimated value exceeds the power consumption set value and consumes too much power. If a warning image is displayed, a warning image is displayed.

(Screen saver)
Next, based on FIG. 10, an example of the screen saver in the programmable display 1 which concerns on embodiment of this invention is demonstrated. FIG. 10 is an explanatory diagram showing an example of a screen saver in the programmable display device 1 according to the embodiment of the present invention.

  Generally, in a display device, burn-in may occur, depending on the display method of the display screen 11. In particular, the programmable display device 1 of the present embodiment displays certain image data related to the management of buildings such as buildings created by the image data creation program 27, for example, so that the display content is not as diverse as a television or a personal computer. . Therefore, the HMI control unit 10 of the present embodiment stores, for example, in the data memory 15 if there is no input from the user for a predetermined time (for example, several minutes, the time measuring unit 10b measures time) in order to protect the display screen 11. Launch the screen saver software.

  And as shown as an example in FIG. 10, in the programmable display 1 of this embodiment, the power consumption status image 3 in each power distribution system can be displayed on the display screen 11 as a screen saver. In the example shown in FIG. 10, a text component image P indicating a department name as a power distribution system and a power consumption status image 3 associated therewith are arranged in a balloon-like figure P50. Then, for example, the balloon-shaped figure P50 moves, and the text and the power consumption status image 3 also move. By using such a screen saver image 11a, each user can be made aware of energy saving. That is, the display screen 11 is switched to the screen saver image 11a after a predetermined time has elapsed after the input to the touch panel 12 is lost, and the power consumption status image 3 is displayed as the screen saver image 11a.

(Example of display in the eco display column P5)
Next, a display example of the eco display column P5 on the display screen 11 according to the embodiment of the present invention will be described with reference to FIG. FIG. 11 is an explanatory diagram of a display example of the eco display column P5 on the display screen 11 according to the embodiment of the present invention. The eco display column P5 is resident on the display screen 11 as shown in FIGS. Therefore, even if the power consumption status image 3 is displayed in the eco display column P5, the user can be made aware of energy saving. In the eco display column P5, the power consumption status of a large number of departments (distribution systems) may be displayed. However, in this example, it is assumed that the overall power consumption status is displayed in the eco display column P5. .

  First, in the example illustrated in FIG. 11A, as described above, face-shaped figures (3 a to 3 d) are used as the power consumption status image 3. Then, the display is switched according to the estimated power consumption of all the departments. On the other hand, the star-shaped figure 3e and the leaf-shaped figure 3f are relatively often used as a figure indicating the degree of energy saving in an electric device or the like. Therefore, in the display of the eco display column P5, the face-shaped figure is changed to FIG. ) May be used as the power consumption status image 3, and the leaf shape 3 f may be used as the power consumption status image 3 as shown in FIG. When the star-shaped figure 3e and the leaf-shaped figure 3f are used, for example, the degree of power consumption may be expressed by the number. For example, as shown in FIGS. 11B and 11C, the smaller the estimated power consumption of all the departments, the greater the number of star-shaped figures 3e and leaf-shaped figures 3f, and the estimated power consumption of all the departments. When the value exceeds the set value, the power consumption status is displayed so that the star-shaped figure 3e and the leaf-shaped figure 3f disappear.

  In the example shown in FIGS. 11A to 11C, the power consumption status image 3 and a band graph corresponding to the power consumption status are arranged below the power consumption status image 3. The band graph corresponds to each stage of the power consumption situation image 3, and the shaded portion extends to the right in FIG. 11 as the calculated estimated value is smaller and the power consumption is smaller. When the calculated power consumption estimated value exceeds the power consumption set value and the power consumption is excessive, the shaded portion disappears. It should be noted that the power consumption status may be expressed by a band graph by a method such as overlapping different colors instead of shading.

  In this way, according to the configuration of the present invention, the estimated value of the power consumption of the distribution system is calculated from the operation status such as ON / OFF of each device instead of the actual measurement result. However, a measuring device such as a watt hour meter is not necessary. In addition, since the programmable display 1 accepts settings and inputs related to the operation of the device, the calculation and display related to the power consumption status can be realized by the programmable display 1 alone, and expensive equipment such as BEMS, room, floor, department It is not necessary to add measuring equipment for each lighting and air conditioning distribution system, and the configuration required for checking the power consumption can be reduced. Furthermore, in the actual power consumption measurement, it took a certain amount of time for the result of the device setting change to appear as a measurement result, and there was a time delay until the result was reflected in the power consumption status. The setting change is reflected in the power consumption status image 3 in real time. Therefore, the user can immediately recognize the energy saving effect and waste at the time of operation, and can aim at thorough awareness of energy saving to the user.

  Further, for example, each device can be allocated to an arbitrary power distribution system such as a floor, a department, a room, and the power consumption status of each power distribution system can be confirmed. In addition, it is possible to flexibly cope with a layout change on the floor, etc., and it is possible to display the power consumption status without requiring an operation such as changing the installation position of the watt hour meter or the like. Further, the warning display allows the user to recognize that the power is consumed excessively. Therefore, thorough awareness of energy saving to the user can be achieved. In addition, since the power consumption status image 3 is displayed in the screen saver image for preventing burn-in of the display screen 11 and the like, the current power consumption status is recognized by the user and the user is made aware of energy saving. Can do. Since the device is composed of the air conditioner 6 and the lighting device 5, the control system 100 composed of the programmable display 1, the air conditioner 6, the lighting device 5 and the like is used for management of buildings such as buildings. be able to. Further, the present invention can be grasped as a method of displaying the power consumption status as shown in FIG.

  Although the embodiment of the present invention has been described, the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.
