Is controlling.

JP 2011-244484 A

  The technique described in Patent Document 1 is intended to control equipment in real time with respect to personnel in a predetermined area, and in a water supply facility or an air conditioning facility, a target state after starting operation There is a time lag before reaching. For example, in a building where the water supply pressure is ensured by controlling the water pump with an inverter without using an elevated water tank in the building, even if the rotation speed of the water pump is increased after the water tap is opened, it is required. There is a time lag until the target state is reached.

  In order to suppress such a time delay and improve user convenience, it is necessary to create a schedule according to the use of the equipment by the user. However, it is difficult to manually set an appropriate schedule.

  An object of the present invention is to provide a facility management apparatus, a facility management method, and a program that can automatically create a schedule for operating a facility.

  The facility management apparatus according to the present invention stores an operation monitoring unit that monitors an operation state of a specific electrical device installed in a building, and a history of the operation state of the specific electrical device monitored by the operation monitoring unit. Using the history of the operation state stored in the history storage unit and the history storage unit, the usage state of the building accessory equipment installed in the building is estimated, and based on the estimated usage state, according to the time zone And an estimation unit that creates a schedule representing the operating state of the building-attached equipment.

And a step of estimating a use state of the facility and creating a schedule representing an operation state of the building-attached facility according to a time zone based on the estimated use state.

  The program according to the present invention is for causing a computer to function as the above-described facility management apparatus.

FIG. 2A is a diagram illustrating an operation example of the first embodiment, and FIG. 2B is a diagram illustrating an operation example to be compared. It is a figure which shows an example of the schedule in Embodiment 1. FIG. FIG. 5 is a flowchart showing a procedure for creating a schedule in the first embodiment. 6 is a block diagram illustrating a configuration example of Embodiment 2. FIG.

  In the embodiment described below, it is assumed that the building is an office building whose main use is an office. However, if the building is a commercial building whose main use is a store, Also good. Moreover, the technique of embodiment described below is applicable not only to a building for non-residential use but also when the building is an apartment house.

  As for building ancillary equipment, water supply equipment that is configured to supply water directly to the water tap using a water supply pump without installing an elevated water tank is assumed. This type of water supply equipment is configured to suppress fluctuations in the water pressure in the water supply pipe by controlling the rotational speed of the water supply pump with an inverter. The method of controlling the feedwater pump includes a constant discharge pressure control that keeps the discharge pressure of the feedwater pump constant, estimates the head pressure of the faucet, and operates the feed pump so that the estimated head pressure is maintained. Estimated terminal pressure constant control is known. In addition, a water supply facility that does not have an elevated water tank generally includes a pressure tank in order to maintain the internal pressure of the water supply pipe that connects the water supply pump and the water tap during periods when water is not used. Yes.

  In the embodiment described below, it is assumed that the structure of the water supply facility is a pressure-increasing water supply method, and the control method of the water supply pump is the estimated terminal pressure constant control. In this water supply facility, a target pressure curve in the relationship between the amount of water supply (rotation speed of the supply pump) and the discharge pressure is determined according to the installation status of the water supply facility. The rotation speed of the feed water pump is controlled by an inverter so as to follow the determined target pressure curve. Therefore, energy consumption in the feed water pump is reduced as compared with a configuration in which the feed water pump supplies water at a constant pressure regardless of the load side requirements.

  The technology of the embodiment described below can be applied not only when the building accessory facility is a water supply facility but also when the building accessory facility is an air conditioning facility. Building ancillary equipment is generally configured by combining a plurality of devices. For example, the water supply equipment includes devices such as a water supply pump, a water supply tap, a pressure tank, and a water supply pipe.

  By the way, when performing the estimated terminal pressure constant control, there are a method of increasing the rotation speed of the water supply pump in a time zone in which water is expected to be used and a method of changing the rotation speed of the water supply pump according to preset conditions. It is considered. This condition means a condition related to the use of water. These systems maintain the water pressure in the water supply pipe by increasing the rotation speed of the water supply pump when water is expected to be used.

  When adopting a method to increase the rotation speed of the water supply pump during the time period in which water is expected to be used, it is necessary to register the time period and the operation state of the water supply pump in a device that controls the operation state of the water supply pump. . The operating state of the feed water pump is represented by the value of the rotation speed of the feed water pump, the value of the discharge pressure of the feed water pump, or the value of the water pressure in the feed water pipe. The operation state of the feed water pump may include a change in the rotation speed or discharge pressure of the feed water pump with time. The time zone and the operating state registered in the device that controls the water supply pump may change due to changes in the day of the week, the season, the person using the building, and the like. Therefore, the time zone and the operating state registered in the device that controls the water supply pump must be adjusted as necessary.

  By the way, when adopting the method of changing the rotation speed of the feed water pump according to the condition, the rotation speed of the feed water pump is changed after the condition is met, so the water pressure in the feed water pipe reaches the target value after the condition is met. A time delay occurs. In this method, the water pressure in the water supply pipe may be greatly reduced depending on the use condition of water, and it may take a relatively long time to restore the water pressure in the water supply pipe. That is, the water pressure in the water supply pipe may fluctuate greatly depending on the water usage.

  The embodiment described below automatically or semi-automatically sets the target value of the water pressure in the water supply pipe according to the time zone while adopting a method (schedule control) for controlling the water supply pump according to the time zone. A configuration example that enables the above will be described. Employing the following configuration reduces time zone registration and adjustment work.

  In the embodiments described below, when it is estimated that the operation state of a specific electric device installed in a building is related to the behavior of a person using the water supply facility, the operation state and water supply of the corresponding specific electric device Based on the relationship with the operating state of the facility, the time zone in which the water supply facility is used is determined. In other words, human behavior is estimated based on the operating state of electrical equipment, and when behavior that may use water is estimated, the time zone in which the relevant behavior occurs is obtained, and the water supply pump is controlled according to the time zone By doing so, it is possible to suppress fluctuations in water pressure in the water supply pipe. In the embodiment described below, a process for determining a time zone for controlling the water supply pump based on the operating state of a specific electrical device, and a process for controlling the water feed pump according to the time zone are a facility management device (hereinafter, "Management device").

  As shown in FIG. 1, the management device 10 manages a water supply facility 21 and an electrical device 30 that are building-attached facilities 20. The water supply equipment 21 and the electrical equipment 30 are installed in a building 40 such as an office building. Examples of places where water is used in the building 40 include a hot water supply room, a toilet, a washroom, and a shower room. In these places, hydrants are arranged. Hereinafter, these places are referred to as “target spaces” without distinction. The specific electrical device 30 is assumed to be a lighting device 31 installed in the target space 41. The lighting device 31 usually means a lighting fixture, but may mean not only one lighting fixture but also a plurality of lighting fixtures as a whole.

  The operation of the lighting device 31 is determined so that it is turned on only when a person uses the target space 41 and is turned off when the target space 41 is not used. For example, when a person operates a switch such as a wall switch provided in the target space 41 to turn on and off the lighting device 31, the lighting device 31 is turned on only during a period in which the person uses the target space 41. Arranged to let them.

  The water supply facility 21 includes a water supply pump 22 of a building 40, a water supply tap 23 installed at a target location, and a water supply pipe 24 that connects between the water supply pump 22 and the water supply tap 23. The water supply equipment 21 includes a pressure tank 25, a pressure sensor 26, and the like. The pressure tank 25 is used to maintain the water pressure in the water supply pipe 24 and suppress fluctuations in the water pressure in the water supply pipe 24, and the pressure sensor 26 monitors the water pressure in the water supply pipe 24. Further, the rotation speed of the water supply pump 22 is controlled by an inverter 27, and the water pressure in the water supply pipe 24 is adjusted by adjusting the rotation speed.

  The management device 10 is provided in a management room of the building 40 or the like. The management apparatus 10 includes a computer as a main hardware element. The computer includes a device selected from a central processing unit (CPU) to which a memory is separately connected, a microcomputer having a memory integrally, and the like. This type of device includes a processor that executes a program. In the present embodiment, the function of the management apparatus 10 described below is realized by the computer executing the program.

  The program may be provided in a state written in a ROM (Read Only Memory), or may be provided in a state written in a recording medium such as an optical disk, a hard disk, or a semiconductor memory, and may be provided via the Internet or mobile communication. It may be provided through a telecommunication line such as a network.

  It is desirable that an input device 101 having a keyboard and a mouse and an output device 102 having a liquid crystal display are connected to the management device 10. Further, the input device 101 and the output device 102 may be provided in a terminal device that communicates with the management device 10. When using a terminal device, the terminal device may be provided in a place different from the building 40 and the management device 10 and the terminal device may communicate with each other through an electric communication line such as the Internet or a mobile communication network.

  The management apparatus 10 controls the operation state of the water supply pump 22 according to the time zone. Therefore, the management apparatus 10 includes a schedule storage unit 11 that stores a schedule in which the operation state of the water supply pump 22 is linked to a time zone, and an instruction unit 12 that instructs the operation state of the water supply pump 22 using the schedule. In this embodiment, the schedule is set as an example in which one day is set as a unit. However, a schedule such as a week unit, a month unit, or a year unit may be used.

  The operation state of the water supply pump 22 is determined by the target value of the water pressure in the water supply pipe 24. In this embodiment, as shown in FIG. 2A, the target value of the water pressure is set in three stages of PH, PL, and P0. The PH is the maximum value in the target value when water is supplied to the high floor of the building, and PL (<PH) is the minimum value in the target value when water is supplied to the high floor of the building. The target value PL is determined to such an extent that a small amount of water can be used by the high-level water faucet 23 and a necessary water head pressure can be secured by the low-level water faucet 23. Thus, during the period in which water is used in the building 40, the operating state of the water supply pump 22 is determined such that the water pressure in the water supply pipe 24 becomes either the target value PH or the target value PL. P0 (<PL) is a target value for a period when water is not used in the building 40, and is defined as a minimum water pressure to be maintained in the water supply pipe 24. That is, the target value P0 is selected during a period in which neither the high-rise floor nor the low-rise floor uses water.

  Hereinafter, the period in which the target value is PH is referred to as a first period T1, the period in which the target value is P0 is referred to as a second period T2, and the period in which the target value is PL is referred to as a third period T3. In the present embodiment, the target value PH is selected in the first period T1 where it is clear that water is used on the higher floor, and the target value is selected in the third period T3 where it is not clear that water is used on the higher floor. Select PL.

  The instruction unit 12 instructs the target value of the water pressure for each time zone stored in the schedule storage unit 11 to the inverter 27, and the inverter 27 maintains the water pressure monitored by the pressure sensor 26 at the target value. The rotational speed of the feed water pump 22 is adjusted. The management device 10 includes a clock unit 13, and the instruction unit 12 reads the water pressure target value from the schedule storage unit 11 using the date and time counted by the clock unit 13, and instructs the inverter 27 of the water pressure target value.

  If an appropriate schedule is set in the schedule storage unit 11, the water pressure in the water supply pipe 24 is adjusted according to the use of water, so that the possibility that the water head pressure necessary for the water tap 23 is insufficient is reduced. And the excess of the water pressure in the water supply pipe 24 is suppressed.

  As a comparative example, a case is assumed in which a two-stage target value is set for the water pressure in the water supply pipe 24 as shown in FIG. 2B. That is, in the control example shown in FIG. 2B, the two-stage water pressures PH and P0 are determined, and the lower water pressure P0 is used as a target value at night when water is hardly used, and is high during the daytime when water is used. The water pressure PH is used as the target value. In this control, the water pressure in the water supply pipe 24 is maintained at the target value (that is, the water pressure PH) when supplying water to the higher floors regardless of the use of water during the daytime.

  If the control shown in FIG. 2A is compared with the control shown in FIG. 2B, the control shown in FIG. 2A has a third period T3 in which the target value of water pressure is set to PL, and the control shown in FIG. The difference is that there are only two stages of PH and P0. Therefore, when the control shown in FIG. 2A is performed, it is apparent that the average value of the rotation speed of the feed water pump 22 is reduced as compared with the case where the control shown in FIG. 2B is performed. Since the power consumption of the water supply pump 22 is proportional to the cube of the rotation speed, the control shown in FIG. 2A reduces the power consumption compared to the control shown in FIG. 2B.

  When the control shown in FIG. 2B is performed, the daytime water pressure in the water supply pipe 24 is maintained at PH, which is a target value for supplying water to the higher floors. The water pressure is maintained at a high level. Therefore, a relatively large stress may be continuously generated in the water supply pipe 24 over a relatively long period. On the other hand, if the control shown in FIG. 2A is performed, the stress generated in the water supply pipe 24 is reduced. For example, even when vinyl chloride is used as the material of the water supply pipe 24, the occurrence of cracks and the like is suppressed. This leads to a reduction in repair costs.

  In the above-described schedule, the water pressure in the water supply pipe 24 is divided into three stages, but it is also possible to define a schedule in which the water pressure in the water supply pipe 24 is divided into four or more stages. That is, it is possible to divide the building 40 into three or more stages rather than two stages of a high floor and a low floor. Further, the target value of the water pressure is appropriately determined according to the specifications of the water supply equipment 21 and the building 40.

  By the way, the management apparatus 10 determines a schedule as shown in FIG. 2A based on the results of using water in the building 40. As described above, in order to determine a schedule for setting the three-stage water pressure to the operation state of the water supply pump 22, information on the place where the water is used (the place where the water tap 23 is opened) and the period during which the water is used is required. It is.

  In the present embodiment, information on whether or not water has been used in the target space 41 is substituted with information on whether or not a person has stayed in the target space 41. Further, information on whether or not a person has stayed in the target space 41 is substituted by information on whether or not the lighting device 31 is turned on. In other words, the management apparatus 10 estimates that water has been used in the target space 41 when the lighting device 31 in the target space 41 in which the water tap 23 is disposed is turned on.

  As shown in FIG. 1, the management device 10 uses the operation monitoring unit 14 that monitors the operation state of the lighting device 31 installed in the target space 41 and the operation state of the lighting device 31 to create a schedule. And an estimation unit 15 that estimates a time zone in which water is used in the space 41. Furthermore, the management device 10 includes a history storage unit 16 that stores the operation state of the lighting device 31 monitored by the operation monitoring unit 14 as a history together with the date and time. The history stored in the history storage unit 16 includes information on at least the location where the lighting device 31 is installed, the time when the lighting device 31 is turned on, and the time when the lighting device 31 is turned off. That is, the management apparatus 10 combines the location where the lighting device 31 is installed, the operation state of the lighting device 31, and the date and time counted by the clock unit 13 for the lighting device 31 monitored by the operation monitoring unit 14. And stored in the history storage unit 16.

  The operation monitoring unit 14 is configured to detect the operation state of the lighting device 31 by a change in the current flowing through the lighting device 31. For example, a current sensor is disposed on an electric path that supplies power to the lighting device 31, and the operation monitoring unit 14 determines whether the lighting device 31 is turned on or off by monitoring the output of the current sensor.

  Although it is desirable that the current sensor be provided in an electric circuit that supplies power only to the lighting device 31, the current sensor may be provided in an electric circuit that supplies electric power to the electric device 30 in the target space 41. For example, when one of the branch circuits branched into a plurality of systems by the distribution board supplies power to the target space 41, the current flowing through the branch circuit is monitored by the current sensor, and the operation monitoring unit 14 outputs the current sensor output. It may be determined whether or not the lighting device 31 is lit based on the change in.

  In the configuration in which the current of the branch circuit is monitored, the output of the current sensor changes even when the electric device 30 other than the lighting device 31 is used in the target space 41, but the electric device 30 in the target space 41 is used. This suggests the possibility that a person exists in the target space 41. However, even when the power consumption of the electric device 30 that is always operating like a refrigerator changes, the output of the current sensor changes. Therefore, whether or not the operation monitoring unit 14 is information suggesting that a person stays in the target space 41 based on the magnitude of the change in the output of the current sensor and the manner of change (change pattern) over time. It is desirable to be configured to discriminate. In short, when the current of the branch circuit is monitored by a current sensor, the operation monitoring unit 14 is information indicating whether a person has stayed in the target space 41 based on the magnitude of the output of the current sensor, a change pattern, or the like. Judging.

  As described above, the output of the current sensor determined by the operation monitoring unit 14 as information suggesting a person's stay in the target space 41 is stored in the history storage unit 16. That is, the history storage unit 16 associates the location of the electrical device 30 that is being monitored for use by the current sensor, the operating state of the electrical device 30 that is determined from the output of the current sensor, and the period during which the electrical device 30 has been operated. Store as history.

  In this embodiment, since the case where the electrical device 30 is the lighting device 31 is taken as an example, the history storage unit 16 stores the location, lighting state, and lighting period (date and time) of the lighting device 31. When the hydrant 23 opens in the target space 41 including the hydrant 23, the estimation unit 15, based on the hypothesis that the illuminating device 31 installed in the target space 41 is lit, the lighting period of the illuminating device 31. Is estimated to be a period during which the faucet 23 is likely to open. In short, paying attention to the lighting period of the lighting device 31 among the information stored in the history storage unit 16, the possibility that water was used in the target space 41 in which the lighting device 31 is installed during the lighting period of the lighting device 31. Is estimated to be high.

  The estimation unit 15 uses the water in the lighting period of the lighting device 31 in the target space 41 regardless of whether or not water is actually used in the target space 41 corresponding to the lighting period of the lighting device 31. Estimated period. Thus, if the period during which water is likely to be used in the target space 41 can be estimated, the target value of the water pressure in the water supply pipe 24 can be determined so as to include the corresponding period. That is, the possibility of operating the feed water pump 22 excessively is reduced.

  When the target space 41 where water is likely to be used is specified, it is possible to determine a target value of the water pressure in the water supply pipe 24 according to the location of the target space 41 in the building 40. That is, the management apparatus 10 sets the high water pressure PH as a target value if the target space 41 uses a relatively large amount of water on the high floor, and sets the low water pressure PL if the target space 41 uses a relatively small amount of water on the high floor. It becomes possible to set the target value. Moreover, the management apparatus 10 determines the water pressure P0 as a target value in the period which does not use water. Specific values of the water pressures PH, PL, and P0 vary depending on the scale of the building 40, the configuration of the water supply equipment 21, and the like, but can be determined by a general design method.

  Moreover, the estimation part 15 determines the time slot | zone which uses water pressure PH, PL, and P0 as a target value. The time zone is determined by the estimation unit 15 based on the target space 41 in which the lighting device 31 is installed and the lighting period of the lighting device 31. Note that the lighting period of the lighting device 31 may vary from day to day, and may vary greatly depending on the day of the week and the season. Therefore, it is desirable that the estimation unit 15 classifies the lighting periods on the condition of day of the week and season, and extracts the lighting periods for each classified condition.

  The estimation unit 15 obtains a lighting period of the lighting device 31 in the target space 41 that sets the water pressure PH as a target value and a lighting period of the lighting device 31 in the target space 41 that sets the water pressure PL as a target value for each classified condition. . By the way, the target space 41 generally has a plurality of locations. For example, in a 10-story building 40, if there is one target space 41 on each floor, there are 10 target spaces 41. If the 6th floor to the 10th floor are high floors, it is necessary to determine the lighting periods of the lighting devices 31 in the five target spaces 41 from the 6th floor to the 10th floor in order to determine the schedule.

  If there are a plurality of target spaces 41 for determining the lighting period of the lighting device 31, the lighting period of the lighting device 31 may be different for each target space 41, but even if these lighting periods are overlapped, There is an extinguishing period between the lighting periods. That is, the period for opening the water tap 23 is a relatively short time, and the lighting period of the lighting device 31 in the target space 41 in which the water tap 23 is arranged is also a relatively short time. Even if they are combined, there is a high possibility that a light extinction period will occur. Note that the overlapping of the lighting periods is, for example, when there is a target space 41 whose lighting period is from 10:00 to 10:15 and a target space 41 whose lighting period is from 10:11 to 10:30. This means that the lighting period is from 10:00 to 10:30.

  The estimation unit 15 extracts a lighting period of the lighting device 31 in the target space 41 using the history stored in the history storage unit 16, and creates a schedule to be stored in the schedule storage unit 11 based on the extracted information. . As described above, the estimation unit 15 includes a person in the target space 41 and a person in the target space 41 in the period when the lighting device 31 installed in the target space 41 is lit. It is estimated that there is a high possibility of using. Therefore, the estimation unit 15 creates a schedule so that a target value of water pressure corresponding to the target space 41 in which the lighting device 31 is installed is obtained at least in a time zone including the lighting period of the lighting device 31.

  Since the period in which water is used in the target space 41 (that is, the period in which the water tap 23 is opened) is considered to be within the lighting period of the lighting device 31, the timing for switching the target value of the water pressure is the lighting period of the lighting device 31. A schedule that matches this can be considered. However, when the target value of the water pressure is switched to a higher value, there is a time delay from when the target value of the water pressure is instructed to the inverter 27 until the water pressure in the water supply pipe 24 reaches the target value. That is, when the target value of the water pressure is changed from P0 to PL, when changed from P0 to PH, or when changed from PL to PH, the target value is instructed to the inverter 27. A time delay occurs until the water pressure in the water supply pipe 24 reaches the target value after the change. Due to this time delay, the water pressure required for the target space 41 may not be obtained before the water is used in the target space 41.

  Therefore, when the target value of the water pressure is increased, the estimating unit 15 creates a schedule in which the timing for instructing the target value is set to a time that is a predetermined adjustment time earlier than the start time of the lighting period obtained from the history. .

  For example, as shown in FIG. 3, when the lighting period Tb of the lighting device 31 obtained from the history is from the time t1 to the time t2, and the adjustment time is Tc, the time before the time t1 by the adjustment time Tc. t0 is set to the time at which the inverter 27 is instructed of the target value. The adjustment time Tc is a time that the water pressure in the water supply pipe 24 reaches the target value after instructing the target value to the inverter 27, the difference between the target value before switching and the target value after switching, It is determined according to the specifications.

  When the target value of the water pressure is lowered, the time for switching the target value may coincide with the time t2 when the lighting period Tb of the lighting device 31 obtained by the estimation unit 15 ends. When the target value of the water pressure is lowered, a higher target value is instructed before the target value is instructed to the inverter 27. Therefore, even if there is a time delay from when the target value is instructed to the inverter 27 until the water pressure in the water supply pipe 24 reaches the target value, the water pressure necessary for water use can be secured. Therefore, when the target value of the water pressure is lowered, a schedule may be created in which the start time of the time when the target value is applied coincides with the time t2 when the lighting period Tb of the lighting device 31 ends.

  The schedule creation procedure is summarized in FIG. As described above, the schedule is determined in units of one day. Here, it is assumed that a history for at least one day is stored in the history storage unit 16. Note that, on the first day when the operation of the management apparatus 10 is started, the target value of the water pressure is set to PH (S11). That is, since the target value of the water pressure is PH in the initial state, the necessary water pressure can be obtained regardless of the location of the building 40.

  When the operation for one day is completed (S12), since the history for one day is stored in the history storage unit 16, the estimation unit 15 records the lighting period of the lighting device 31 installed in the target space 41 on the higher floor. (S13). Next, the estimation unit 15 obtains the first period T1 by superimposing the lighting periods obtained from the target space 41 on the higher floor. Moreover, the estimation part 15 calculates | requires the 2nd period T2 which is not contained in the lighting period calculated | required from the target space 41 of a higher floor within the day, and the lighting period calculated | required from the target space 41 of a lower floor. Furthermore, the estimation unit 15 obtains a third period T3 that is not included in the first period T1 and the second period T2 in one day (S14).

  As described above, the adjustment time Tc is necessary before the start of the first period T1, and the adjustment period Tc is not necessary when shifting from the first period T1 to the third period T3. However, when the water pressure in the water supply pipe 24 is increased during the transition to the third period T3, the adjustment time Tc is required before the start of the third period T3. The adjustment time Tc is determined in advance according to the specifications of the building 40 and the water supply facility 31.

  Under the constraints as described above, the estimation unit 15 creates a schedule (S15). That is, the estimation unit 15 corresponds to PH as a target value of the water pressure in a time zone in which the start time is the time earlier than the start time of the first period T1 by the adjustment time Tc and the end time is the end time of the first period T1. Create a scheduled schedule. When the third period T3 shifts from the second period T2, the estimation unit 15 sets PL as a target value of the water pressure in a time zone having a start time that is earlier than the start time of the third period T3 by the adjustment time Tc. Create a schedule corresponding to. The ending time of this time zone is changed by the estimating unit 15 depending on whether the period transitions from the third period T3 to the first period T1 or from the third period T3 to the second period T2. In the case of shifting from the third period T3 to the first period T1, the start of the first period T1 is advanced by the adjustment time Tc, so this time period is earlier by the adjustment time Tc than the end of the third period T3. On the other hand, when shifting from the third period T3 to the second period T2, the end time of this time zone coincides with the end time of the third period T3.

  The schedule created by the estimation unit 15 as described above is stored in the schedule storage unit 11 (S16). Thereafter, the target value of the water pressure determined in the schedule is delivered to the inverter 27 through the instruction unit 12 according to the time measured by the clock unit 13.

  Since the above-described schedule is created based only on the history for one day, it cannot be said that the schedule is necessarily adapted to human behavior. Therefore, when the history for one day is stored in the history storage unit 16, the estimation unit 15 repeats the processing from step S12 to step S16. When this process is performed, the first period T1 is lengthened by overlapping the lighting periods, but the third period T3 is unlikely to disappear, so the period in which the target value of the water pressure in the water supply pipe 24 is set to PH. In addition to this, a period for setting the target value to PL is generated, and energy saving can be achieved.

  When the lighting periods of the plurality of target spaces 41 are overlapped and the lighting periods of a plurality of days are overlapped, the first period T1 becomes longer as described above. Therefore, as the number of days used for creating the schedule increases, the possibility that the water pressure in the water supply pipe 24 is insufficient is reduced. On the other hand, it is considered that the third period T3 is shortened and the energy saving effect is reduced. . That is, during the period when PH is selected as the target value of the water pressure, the time during which water is not used on the higher floors increases.

  By the way, in the process mentioned above, it does not evaluate with respect to the lighting period of the illuminating device 31, but if it is the lighting period of the illuminating device 31 of the target space 41 in a high-rise floor, it is incorporated in the schedule as a time zone which makes PH a target value. . Therefore, there is a possibility that the time zone in which the target value is set to PH includes a period in which the frequency of using water in the target space 41 is low. That is, the schedule created by the above process includes a period during which the target value is set to PH, even though it is actually a period when there is almost no possibility of using water on a higher floor. .

  The estimation unit 15 evaluates the frequency of using water on the higher floor for the first period T1, and takes in only the period in which the frequency is equal to or higher than a predetermined reference value in the time zone in which the target value is set to PH in the schedule. Is desirable. In order to evaluate the frequency, the estimation unit 15 divides each day into a predetermined unit period for a history of a predetermined extraction period of about one week to one month, for example. And the estimation part 15 evaluates for every unit period whether it is the lighting period of the lighting equipment 31 in the target space 41 of a higher floor, or the lighting period of the lighting equipment 31 in the target space 41 of a lower floor, which is neither. . The unit period is selected from, for example, 1 minute, 10 minutes, 15 minutes, 30 minutes, 1 hour, and the like. Here, the lighting period in the unit period means that one or more lighting periods have occurred in the unit period. Moreover, the estimation part 15 will count the number of the object space 41, if the illuminating device 31 is lighted in the some object space 41 of a high-rise floor.

  Now, in each unit period ti (i = 1, 2,... N) dividing one day, the number of target spaces 41 in which the lighting device 31 is in the lighting period on the higher floor is defined as KH (ti). n varies depending on the length of the unit period ti. When the unit period ti is 1 minute, n = 1440, and when the unit period ti is 30 minutes, n = 48. For each unit period ti, the estimation unit 15 obtains the number KH (ti) of the target space 41 in which the lighting device 31 is in the lighting period on the higher floor and obtains the total number KH (ti) in the extraction period. When the sum of KH (ti) is represented by ΣKH (ti), the sum ΣKH (ti) reflects the frequency of using water on higher floors. The probability that water is used on the higher floor in the unit period ti is represented by ΣKH (ti) / q · p. Here, q is the number of days included in the extraction period, and p is the number of target spaces 41 on the higher floors.

  For example, the number of days q of the extraction period is 7, the number p of the target spaces 41 on the higher floors is 10, and the lighting device 31 is in the lighting period in the unit period t100 (i = 100) of each day included in the extraction period. It is assumed that the total ΣKH (t100) of the target space 41 is 56. In this case, according to the above equation, 56 / (7 × 10) = 0.8, and the probability that water is used in the unit period t100 on the higher floor is 0.8.

  The estimation part 15 calculates | requires the probability that water will be used on a high floor for every unit period ti as mentioned above. Furthermore, the estimation unit 15 compares these probabilities with a reference value, and creates a schedule using a unit period ti in which the probability is greater than or equal to the reference value. The reference value can be determined as appropriate, but it is generally desirable to set the reference value to 50% or more. However, the reference value can be set to less than 50%, and the smaller the reference value, the lower the possibility that the water pressure is insufficient when water is used in the target space 41.

  As described above, when the estimation unit 15 creates a schedule based on the probability of using water in the target space 41, there is no possibility that a time delay will occur before the water pressure increases. However, if the reference value is set appropriately, it is possible to create a schedule that does not cause inconvenience. Moreover, the effect of energy saving becomes comparatively high by appropriately setting the reference value.

  In the above-described operation, the estimation unit 15 divides the history of the extraction period into unit periods ti. However, the history storage unit 16 stores the history of turning on (ON) and turning off (OFF) of the lighting device 31 for each unit period ti. May be stored. In other words, the operation monitoring unit 14 may acquire the operation state of the lighting device 31 for each unit period ti and store it in the history storage unit 16. If such a configuration is adopted, the lighting period of the lighting device 31 is determined by dividing it into unit periods ti, so that the time zone in the schedule is also set by the increment of the unit period ti. For example, if the length of the unit period ti is 15 minutes, the lighting period history of the lighting device 31 is stored in the history storage unit 16 in units of 15 minutes, and the schedule time zone is created in increments of 15 minutes. .

  By the way, when a schedule is created based on the probability of using water in the target space 41, the probability may vary greatly depending on the attribute of the day used for calculating the probability. For example, the period of using water in the target space 41 may differ depending on whether the day attribute is a weekday or a holiday. Therefore, the days used for the probability calculation must be divided into groups according to the day attributes. The day attribute may be a day of the week.

  In addition, the season may affect the period in which water is used in the target space 41. The influence of the season can be dealt with by changing the extraction period for obtaining the probability. For example, if the extraction period is one week, the season can be reflected in the schedule by updating the schedule every week. If the extraction period is one month, the schedule may be updated every half month.

  When creating a schedule using the probability that water will be used in the target space 41, information for determining the probability cannot be obtained immediately after the operation of the water supply facility 21. Therefore, on the first day when the water supply facility 21 is introduced, the schedule is determined so as to use the maximum target value throughout the day. From the second day onward, the probability can be obtained, but the amount of information is small and the reliability of the obtained probability is low until the number of days in the extraction period is reached. A schedule may be created using the first period T1 and the third period T3 obtained by superimposing. After the number of days of operation of the water supply facility 21 reaches the number of days in the extraction period, the probability may be obtained by the above-described process, and a schedule based on the probability may be created.

  With the configuration described above, when the operation of the management apparatus 10 is started, the estimation unit 15 automatically creates a schedule for determining the operation state of the water supply pump 22, so that it is possible to save labor for manually creating the schedule. . The schedule is shown to the user of the management apparatus 10 through the output apparatus 102, and the user can correct the schedule using the input apparatus 101 if necessary.

  In the configuration example described above, it is assumed that the water supply facility 21 is used during the lighting period of the lighting device 31 installed in the target space 41, but the water supply facility 21 is used during the lighting period of the lighting device 31 in the target space 41. May not be used. In particular, when the staying time of a person in the target space 41 is short, there is a high possibility that the person does not use the water supply equipment 21. In other words, when the lighting time of the lighting device 31 in the target space 41 is short, the water supply facility 21 may not be used in the target space 41. Therefore, not only information that the lighting device 31 in the target space 41 is turned on, but also information on the length of the lighting period is evaluated, and a schedule is created as a period in which the water supply facility 21 is not used when the lighting period is equal to or less than the threshold value. You may exclude from the information for doing.

  By the way, in the configuration example described above, the probability that water is used on the higher floor is obtained based on the number KH (ti) of the target spaces in which the lighting device 31 is in the lighting period. It can be said that the information reflects the number of people in the target space on the higher floors. There are cases where a plurality of people enter the target space, but when one person enters the target space, this probability is the ratio of the number of people to the total number of target spaces on the higher floors.

  When the unit period ti is set relatively long (for example, when the unit period ti is 10 minutes or more), there is a possibility that the lighting period occurs several times for one target space in the unit period ti. . In the above-described operation example, when the lighting period is included in the unit period ti, it is counted once. However, the number of lighting periods in the unit period ti may be counted. In this case, the probability of using water for each target space can be obtained.

  By the way, the phenomenon that several people open the water faucet 23 in one lighting period in one object space can be considered. In particular, when a plurality of water faucets 23 are arranged in one target space, the possibility of such an event increases. Therefore, the management apparatus 10 may employ a configuration that takes into account the number of people who have entered the target space in order to obtain the probability of using water on a higher floor for each unit period ti. For example, it is possible to employ a configuration in which a camera is installed above the entrance and exit of the target space and the number of people entering and leaving the target space is counted using images captured by the camera. In addition, the entrance and exit of the target space may be combined.

(Embodiment 2)
In the first embodiment, an example has been described in which a person performs an instruction to turn on and off the lighting device 31 disposed in the target space 41 by operating a switch. In the present embodiment, as shown in FIG. 5, an example in which the human sensor 32 is arranged in the target space 41 and the lighting device 31 is turned on and off by the output of the human sensor 32 will be described. That is, when the human sensor 32 detects the presence of a person in the target space 41, the output of the human sensor 32 is turned on and the lighting device 31 is turned on, and when the human sensor 32 no longer detects the presence of a person, The output of the sensor 32 is turned off and the lighting device 31 is turned off. Therefore, the lighting device 31 is automatically turned on when there is a person in the target space 41, and is automatically turned off when there is no more person from the target space 41, regardless of the operation of the switch.

  This kind of human sensor 32 may be provided in the target space 41 and may be provided integrally with the lighting device 31. The human sensor 32 is assumed to have a pyroelectric infrared sensor. The human sensor 32 using the pyroelectric infrared sensor is generally configured to turn off the output after a certain holding time has elapsed from the time when the person goes out of the field of view.

  The human sensor 32 includes a retriggerable timer triggered by a change in the output of the pyroelectric infrared sensor. The human sensor 32 includes a timer because the pyroelectric infrared sensor is a differential sensor, and an output can be obtained only when a change occurs in the received heat dose. That is, even if the change in the heat dose received by the pyroelectric infrared sensor temporarily stops due to the person temporarily resting within the field of view of the pyroelectric infrared sensor, the timer 32 is used to detect the human sensor 32. It is possible to maintain the output.

  The timer receives a trigger and performs an operation of measuring a holding time, which is a predetermined time, and turns on the output of the human sensor 32 during the holding time. The output of the human sensor 32 is turned off when the timer finishes the operation of measuring the holding time. Since the timer is retriggerable, when a timer is received while the timer performs the operation of measuring the holding time, the holding time is further counted from the time when the trigger is received. The holding time can be set appropriately, and is normally set in the range of about 5 seconds to 3 minutes.

  With the configuration described above, as long as the timer is triggered within the holding time, the output of the human sensor 32 remains on. In other words, if there is a person in the field of view of the pyroelectric infrared sensor and the time during which the person is stationary does not exceed the holding time, the output of the human sensor 32 is kept on. When a person goes out of the field of view of the pyroelectric infrared sensor, the output of the human sensor 32 is turned off when the holding time has elapsed since the last trigger was input to the timer.

  When the lighting sensor 31 is controlled to be turned on and off by using the human sensor 32, the lighting device 31 is automatically turned on when a person enters the target space 41 without operating a switch. The lighting equipment automatically turns off when a person leaves. In other words, compared to the case where the lighting device 31 is turned on and off by operating the switch, the presence and absence of a person in the target space 41 can be more reliably associated with the lighting device 31 being turned on and off. become.

  By the way, even when a person enters the target space 41, the person does not always use the water supply equipment 21 in the target space 41. Further, when the human sensor 32 detects a person passing near the target space 41, the lighting device 31 may be temporarily turned on even if the person does not enter the target space 41. On the other hand, it is reasonable to assume that the longer the period during which a person stays in the target space 41, the higher the probability of using the water supply equipment 21 in the target space 41.

  Therefore, when the human sensor 32 is used, it is assumed that the lighting period of the lighting device 31 and the staying period of the person in the target space 41 are substantially the same, and the longer the lighting period of the lighting device 31 is, the longer the target space 41 is. It is assumed that the probability that a person uses the water supply equipment 21 is high. In the present embodiment, the lighting period of the lighting device 31 is a period from when the lighting device 31 is turned on to when the lighting device 31 is turned off, and includes a holding time.

  In order to determine the probability of using the water supply facility 21 in the target space 41, the estimation unit 15 determines an appropriate threshold for the lighting period of the lighting device 31, and if the lighting period exceeds the threshold, the estimation unit 15 estimates that the probability is high. If the period is less than or equal to the threshold, it is estimated that the probability is low. In other words, the estimation part 15 classifies into a period with high possibility of using the water supply equipment 21 for every lighting period, and a low period using the threshold with respect to the length of a lighting period.

  The estimation unit 15 creates a schedule using only the lighting period determined to have a high probability among the lighting periods of the lighting device 31 installed in the target space 41. In other words, since the lighting period with a low probability is that the lighting period of the lighting device 31 in the target space 41 is short, the estimation unit 15 determines whether the human behavior has passed near the human sensor 32 or is in the target space 41. Although it entered, it estimates that the water supply equipment 21 was not used. Since it is estimated that the water supply facility 21 is not used when the lighting period is equal to or less than the threshold, the estimation unit 15 does not use the low-probability lighting period for creating the schedule.

  The threshold value for the lighting period of the lighting device 31 installed in the target space is desirably set according to the purpose of use of the target space. For example, the threshold value is set according to the purpose of use of the target space because it is considered that the time in which the person stays in the target space differs between the case where the target space is a hot water supply room and the case where the target space is a restroom. It is desirable. However, since it is only necessary to determine the possibility that a person uses the water supply facility 21 in the target space based on the length of the lighting time, the minimum time of the lighting device 31 when the water supply facility 21 is used is set as the minimum time of the target space. It is also possible to set a certain threshold regardless of the purpose of use.

  The threshold value to be compared with the lighting period can be determined based on the holding time set for the human sensor 32. Further, the threshold value may be corrected while the water supply equipment 21 is operated. As the threshold value, a holding time can be adopted, but it is desirable to use a time obtained by adding an appropriate correction value to the holding time, a time obtained by multiplying the holding time by one or more coefficient values, and the like.

  By the way, in order to appropriately set the threshold for the lighting period, it is desirable to adjust the threshold in the process of operating the management apparatus 10. The holding time can be used as an initial value before adjusting the threshold. Using the holding time as the initial value of the threshold means that when the threshold is adjusted, the threshold value is adjusted to start from a minimum value and to be increased. As the initial value of the threshold value, an appropriately determined value that is not the holding time can be used. However, since the minimum value of the lighting period of the lighting device 31 is the holding time, it is desirable to set the holding time as the initial value. . If the holding time is set to the initial value of the threshold value, all lighting periods are initially adopted, and it is possible to exclude lighting periods that are irrelevant to the use of the water supply equipment 21 in the process of operating the management apparatus 10. In addition, when correcting a threshold value in the process of operating the management apparatus 10, it is desirable to correct a correction value to be added to the holding time or a coefficient value to be multiplied by the holding time.

  As described above, in order to optimize the threshold value, the threshold value is adjusted so as to increase with the initial value of the threshold value as the holding time. Although the adjustment range of the threshold value once is arbitrary, for example, it is possible to adjust the holding time as a unit. Assuming that the holding time is Tc, the initial value of the threshold value when adjusting the threshold value is Tc. Thereafter, the threshold value is evaluated based on an evaluation criterion that the threshold value is increased in increments of Tc and the energy consumption of the feed water pump 22 is minimized. To do. The meaning of making it as small as possible is that it is not a true minimum, but is a minimum at a threshold value in steps of Tc. When the holding time Tc is used as the adjustment range, the value obtained by adding the correction value to the holding time Tc is equal to the value obtained by multiplying the holding time Tc by the coefficient value.

  An example of adjusting the threshold will be described. For example, the threshold is expressed as i · Tc (i is an integer), and i is increased from 1 in order. Here, it is assumed that the energy consumption of the feed water pump 22 decreases as the threshold increases until i = n−1, and the energy consumption of the feed water pump 22 increases as the threshold increases when i = n. In this case, the threshold value for reducing the energy consumption of the feed water pump 22 as much as possible is (n−1) · Tc.

  Using the history stored in the history storage unit 16 as described above, the threshold value that contributes to energy saving can be determined by evaluating the threshold value based on the evaluation criterion of making the energy consumption of the water supply pump 22 as small as possible. Although the threshold can be determined based on the history of the extraction period described in the first embodiment, it takes time from the start of operation of the management apparatus 10 to the determination of the threshold. Therefore, it is desirable to use the initial value of the threshold value as a temporary threshold value and adjust the threshold value in the process of operating the management apparatus 10.

  Other configurations and operations are the same as those of the first embodiment. In the present embodiment, the lighting device 31 is controlled to be turned on and off by the output of the human sensor 32, and the lighting period of the lighting device 31 is set to a threshold value, and the lighting period equal to or less than the threshold value is not used for creating the schedule. Is different from the first embodiment. In addition, the technique which compares a lighting period with a threshold value can be employ | adopted in the technique of Embodiment 1. FIG.

  In addition, the configuration in which lighting and extinguishing of the lighting device 31 are interlocked with the operation of the switch as in the first embodiment, and the configuration in which the lighting device 31 is turned on and off by the output of the human sensor 32 as in the second embodiment. It is also possible to use together. For example, the lighting device 31 may be turned on by operating a switch, and the lighting device 31 may be turned off when the output of the human sensor 32 is turned off. That is, operating the switch to turn on the lighting device 31 means that the person is consciously entering the target space. When the lighting device 31 is turned off by the output of the human sensor 32, the person from the target space is turned off. When it comes out, the illumination device 31 is surely turned off. In other words, the period during which a person is in the target space and the lighting period of the lighting device 31 arranged in the target space can be substantially matched.

  As described above, the facility management apparatus 10 according to the embodiment includes the operation monitoring unit 14, the estimation unit 15, and the history storage unit 16. The operation monitoring unit 14 monitors the operation state of a specific electrical device (lighting device 31) installed in the building 40. The history storage unit 16 stores a history of operation states of the specific electrical device (lighting device 31) monitored by the operation monitoring unit. The estimation unit 15 estimates the usage state of the building ancillary equipment (water supply equipment 21) installed in the building 40 using the history of the operation state stored in the history storage unit 16, and based on the estimated usage state, A schedule representing the operating state of the building ancillary equipment (water supply equipment 21) according to the time zone is created.

  Such a facility management apparatus 10 is realized using a computer. That is, a program for causing a computer to function as the facility management apparatus 10 is used.

  In the present embodiment, the facility management method includes a step of monitoring the operating state of a specific electrical device (lighting device 31) installed in the building 40, and a building ancillary facility (water supply facility 21) corresponding to a time zone. Creating a schedule representing the operating state of the system. In the step of creating the schedule, the usage state of the building-attached equipment (water supply equipment 21) installed in the building 40 is estimated using the history of the operating state of the specific electrical equipment (lighting equipment 31). Furthermore, in this step, a schedule is created based on the estimated usage state.

  Such a facility management method is realized by causing a computer to execute a program. That is, the program monitors the operation state of a specific electrical device (lighting device 31) installed in the building 40 and the operation state of the building accessory facility (water supply facility 21) according to the time zone. And a step of creating the represented schedule. The computer that executes the step of creating the schedule estimates the use state of the building accessory facility (water supply facility 21) installed in the building 40 using the history of the operation state of the specific electrical device (lighting device 31). In this step, the computer creates a schedule based on the estimated usage state.

  According to the above-described configuration, the schedule for operating the building accessory is automatically made based on the operating state of the electrical equipment. As a result, it is possible to save the trouble of manually creating the schedule.

  In the facility management apparatus 10 of the present embodiment, the building-attached facility is a water supply facility 21 including a water supply pump 22 and a water supply pipe 24, and specific electrical equipment is installed in the building 40 where the water supply facility 21 supplies water. It is the illumination device 31 made. The estimation unit 15 determines that the lighting period of the lighting device 31 is a period in which water is used in the place. Moreover, the estimation part 15 estimates the use condition of the water supply equipment 21 in the said period, and produces the target value of the water pressure in the water supply pipe 24 according to a time slot | zone as a schedule based on the estimated use condition.

  According to this configuration, the period during which the lighting device 31 is lit in the place where the lighting device 31 is disposed is determined as the period in which water is used in the place, and the water supply pipe 24 is used by using the period. The target value of the water pressure is set. Therefore, it is possible to automatically create a schedule for driving the water supply equipment 21 with attention to the behavioral habits of the person using the target space 41.

  The facility management apparatus 10 further includes an instruction unit 12 that instructs a target value of the water pressure in the water supply pipe 24 according to a schedule according to a schedule.

  According to this structure, since the schedule mentioned above is performed and the target value of the water pressure in the water supply pipe 24 is adjusted according to the time zone, the water pressure in the water supply pipe 24 is changed only during a period when there is a high possibility of using water. Control such as raising is possible. In other words, since the water pressure in the water supply pipe 24 is adjusted according to the possibility that water is used, the average value of the water pressure in the water supply pipe 24 is reduced, and as a result, energy saving is achieved. The stress on 24 is reduced.

  It is desirable that the history storage unit 16 stores the ON operation state for a specific electrical device (lighting device 31) only when the period during which the specific electrical device (lighting device 31) is on exceeds a predetermined threshold. .

  According to this configuration, when the operation period of the specific electrical device (lighting device 31) is equal to or less than the threshold value, the building accessory facility (water supply facility 21) is not used at the place where the specific electrical device is installed. Estimate and exclude from history. In other words, since the history is used only when there is a high possibility that the building ancillary equipment (water supply equipment 21) has been used, the reliability of the information used for creating the schedule is increased, and the possibility of creating a better schedule is increased. Can do.

  Moreover, it is desirable that the history storage unit 16 stores the operation state of on and off for a specific electrical device (lighting device 31) for each unit period.

  When this configuration is adopted, since the history of ON / OFF of a specific electric device (lighting device 31) is stored for each unit period, the time zone of the schedule to be created is also divided by the unit period.

  By the way, the lighting device 31 is controlled by the output of the human sensor 32 that detects the presence of a person, a period during which the human sensor 32 detects a person, and a certain period after the human sensor 32 stops detecting a person. The lighting device 31 may be turned on during the holding time. In this case, the history storage unit 16 is configured to store the lighting operation state for the lighting device only when the lighting period of the lighting device 31 exceeds a predetermined threshold value, and the threshold value has a minimum holding time. It is desirable to be determined.

  According to this configuration, when the lighting period of the lighting device 31 is equal to or less than the threshold value, it is estimated that the water supply facility 21 has not been used at the place where the lighting device 31 is installed, and is excluded from the history target. . That is, since only the case where the possibility of using the water supply facility 21 is high is used as the history, the reliability of the information used for creating the schedule is increased, and the possibility of creating a better schedule can be increased. In addition, since the threshold value for the lighting period sets the holding time to the minimum value, for example, if the threshold value matches the holding time, the water supply equipment 21 is used even if the lighting device 31 is turned on by passing a person. Avoid misjudgment.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it can be changed.
