Description

  The present invention relates to a building equipment control system.

  In general, a building such as a house is provided with equipment such as an air conditioner or a lighting device that operates by receiving power supplied from a commercial power system or the like. In addition, from the viewpoint of energy saving and power cost saving, a power supply device such as a solar panel or a fuel cell may be installed in a building separately from a commercial power system (for example, Patent Document 1).

  Equipment such as equipment and power supply equipment may be deteriorated by long-term use. For example, in the air conditioner, the cooling capacity is lowered when the air conditioner is operated, and in the power supply equipment, the power supply capacity (in other words, the power generation capacity) is lowered when the supply equipment is operated. Sometimes.

  Here, a deterioration diagnosis system that performs deterioration diagnosis of devices has been known. As this type of system, for example, there is a system in which an operation history of a device is stored in a storage unit, and a deterioration diagnosis is performed based on the stored operation history, specifically based on the operation time of the device. According to this, since it is possible to confirm the deterioration of the device, it is possible to take appropriate measures such as performing maintenance when the device deteriorates.

JP 2007-336656 A

  By the way, it is conceivable that the progress of deterioration of a device varies depending not only on the operation time of the device but also on the installation environment of the device. For example, for two devices with the same operating time, if one device is installed in a normal temperature environment and the other device is installed in a high temperature environment, the device installed in a high temperature environment However, it is considered that the progress of deterioration may be accelerated. Therefore, there is a possibility that the deterioration diagnosis cannot be suitably performed in the system that performs the deterioration diagnosis of the device based only on the operation time of the device.

  The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a building equipment control system capable of suitably performing equipment deterioration diagnosis.

  In order to solve the above-described problem, a building equipment control system according to a first aspect of the present invention is a building equipment control system including equipment provided on the indoor side or the outdoor side of a building, and operation information relating to the operating status of the equipment. Operation information acquisition means for acquiring the installation environment acquisition means for acquiring the installation environment information related to the installation environment of the device, and the operating environment of the device acquired by the operation information acquisition means at the time of acquisition, the acquisition of the installation environment An operation history storage unit that stores the operation history together with the installation environment of the device acquired by the unit, a deterioration diagnosis unit that performs a deterioration diagnosis of the device based on the operation history stored in the operation history storage unit, It is characterized by providing.

  The progress of deterioration of the equipment installed in the building changes depending on the operating time and operating load of the equipment, but it may be changed depending on the installation environment of the equipment. In short, it is considered that the progress of deterioration differs between the case where the installation environment of the equipment is normal temperature and the case where the temperature is lower or higher than that, for example, when the installation environment is extremely high temperature, the progress of the deterioration is likely to occur. It is thought to be promoted. In this regard, according to the present invention, the operation status of the device is stored as an operation history together with the installation environment of the device at the time of operation, and the deterioration diagnosis of the device is performed based on the stored operation history. Therefore, for example, when the installation environment is extremely high, it is possible to perform a deterioration diagnosis taking into account the installation environment of the device, such as diagnosing that the progress of deterioration is relatively fast. Thereby, the deterioration diagnosis of an apparatus can be performed suitably.

  In the building equipment control system according to the second invention, in the first invention, the operation information acquisition means calculates the actual operation capability of the device and acquires the calculated actual operation capability as the operation information. The operation history storage unit stores the actual operation capability of the device acquired by the operation information acquisition unit as the operation history together with the installation environment of the device acquired by the installation environment acquisition unit at the time of acquisition, The deterioration diagnosis means, comprising: extraction means for extracting from the operation history storage means past actual operating capability of the equipment in the same or substantially the same installation environment as the current installation environment of the equipment acquired by the installation environment acquisition means; Compares the current actual operating capacity acquired by the operating capacity acquisition means with the past actual operating capacity of the apparatus extracted by the extracting means. And performing of diagnostics.

  According to the present invention, the deterioration diagnosis is performed by comparing the past actual operation capability of the device in the same or substantially the same installation environment as the current installation environment of the device with the current actual operation capability. That is, a comparison is made between the current actual operation capability and the past actual operation capability under the same equipment installation environment. As a result, when a decrease in operating capacity is observed in the device, it can be determined that the decrease is not due to a change in the installation environment, so that the deterioration diagnosis of the device can be more suitably performed. Further, in this case, since the criterion for deterioration determination is set according to the past operation status, deterioration determination conforming to actual operation can be performed for each device.

  A building equipment control system according to a third aspect of the present invention is the first or second aspect of the invention, wherein the equipment includes an air conditioner that performs air conditioning in the building, and an outdoor unit of the air conditioner is installed outdoors.

  In an air conditioner, deterioration such as a decrease in cooling capacity (or heating capacity) may occur due to long-term use or the like. The cooling capacity of an air conditioner not only fluctuates (decreases) due to deterioration of the air conditioner, but also depends on the indoor environment such as the temperature and humidity of the indoor space to be air conditioned and the outdoor environment such as outdoor temperature and humidity. fluctuate. Therefore, when a decrease in cooling capacity is confirmed, it is difficult to determine whether this is due to deterioration of the air conditioner or due to fluctuations in the indoor environment or the outdoor environment. Therefore, in the present invention, in view of this point, the deterioration diagnosis of the air conditioner is performed based on the indoor environment and the outdoor environment in addition to the operation status of the air conditioner. In this case, when a decrease in the cooling capacity of the air conditioner is observed, it is possible to determine whether it is due to deterioration of the air conditioner or due to fluctuations in the indoor environment or outdoor environment, and as a result, the air conditioner. The deterioration diagnosis can be suitably performed.

  According to the present invention, based on the deterioration status of the power supply device, it is determined which of the power supply device and the commercial power system is to be prioritized to supply power to the electrical equipment device. Therefore, for example, when the power supply device is deteriorated, power can be supplied to the electrical equipment device with priority from the commercial power system over the power supply device. Thereby, since the operating load of the power supply device in which deterioration has occurred can be reduced, the power supply device can be prolonged.

  In addition, when the power supply device has a power generation function for generating power using fuel and supplies the generated power to the electrical equipment, when the power supply device is deteriorated and its power generation efficiency is reduced From the viewpoint of energy saving, it is not preferable to supply electric power to the electrical equipment from the deteriorated power supply device. In that respect, according to the present invention, power can be supplied to the electrical facility equipment in preference to the commercial power system over the deteriorated power supply equipment, so that it is possible to suppress the loss of energy saving even if the power supply equipment is deteriorated. can do.

It is characterized by comprising operation limiting means for performing

  If the device is operated in a state where the deterioration has progressed, inconveniences such as an increase in energy consumption compared to before the deterioration and a shortening of the life of the device due to the advancement of the deterioration are caused. In this regard, according to the present invention, when it is diagnosed that the device is deteriorated, operation restriction is performed on the device. Therefore, for example, it is possible to limit the operating time per day of the device or to set an upper limit on the operating load of the device. Thereby, said inconvenience can be suppressed.

  When the operation is restricted by the operation restriction unit, the degree of operation restriction on the device may be adjusted according to the deterioration state of the device diagnosed by the deterioration diagnosis unit. For example, if the device has just started to deteriorate, the device operation time will be shortened slightly compared to the normal operation time. If the device deterioration has progressed significantly, the device operation time will be greatly increased. It may be shortened. Thereby, it is possible to perform an appropriate operation restriction according to the deterioration state of the device.

  According to the present invention, based on the biological information of the person in the building, it is determined whether or not the environment adjustment in the building is required due to the operation of the device. If it is determined that the environment adjustment is required, the device deteriorates. Even if this is done, device operation restrictions are not enforced. Here, examples of the device for adjusting the environment in the building include a device for adjusting the temperature environment or the humidity environment in the building such as an air conditioner. In this case, for example, even if the air conditioner is in a deteriorated state, if the user has a cold, the air conditioner can be used (for example, heating operation) without restricting the operation. Thereby, when the device is deteriorated, it is possible to use the device giving priority to the physical condition of the user.

Here, each of the sensors 51 to 54 corresponds to installation environment acquisition means.

  The building 10 is provided with a management server 60 for managing this system. The management server 60 is provided on the inner wall surface of the living room 19, for example. Next, the electrical configuration of the present system will be described with reference to FIG. FIG. 2 is a block diagram showing an electrical configuration of the device control system.

  As shown in FIG. 2, the management server 60 includes a controller 61 as a deterioration diagnosis unit, an operation unit 62 operated by a user, and a display unit 63 that displays various types of information. The controller 61 is connected to the operation unit 62, the display unit 63, and the notification unit 64.

  The controller 61 is configured by a known microcomputer having a CPU and the like, and includes a storage unit 66 that stores operation information and the like of each device.

  The operation unit 62 includes, for example, a keyboard. When an operation is performed on the operation unit 62, an operation signal corresponding to the operation is input to the controller 61.

  The display unit 63 includes a display, for example. When various types of information are input from the controller 61 to the display unit 63, the input information is displayed on the display unit 63.

  The notification unit 64 includes a speaker that outputs sound. When a notification signal is input from the controller 61 to the notification unit 64, sound is output from the notification unit 64.

  The controller 61 receives the room temperature sensor 51 from the room temperature sensor 51, the outdoor temperature sensor 52 from the outdoor temperature, the solar radiation sensor 53 from the solar radiation amount, and the illuminance sensor 54 from the illuminance sensor 54 to the room temperature 19.

  The controller 61 receives the power generation amount by the solar panel 15 from the panel watt hour meter 35 sequentially. The controller 61 calculates the power generation capacity (corresponding to the actual operation capacity) of the panel 15 based on the input power generation amount of the solar panel 15. Specifically, the controller 61 calculates the power generation amount per unit time in the panel 15 at a predetermined time, that is, the generated power as the power generation capacity. Then, the controller 61 associates the calculated (acquired) generated power of the solar panel 15 with the solar radiation input from the solar radiation sensor 53 at the time of acquisition of the generated power, and stores it in the storage unit 66 each time. . Therefore, the storage unit 66 stores the power generation history information (corresponding to the operation history) regarding when and how much power is generated by the solar panel 15 in association with the solar radiation amount history.

  The amount of power generated by the power generation unit 16 is sequentially input from the unit watt hour meter 36 to the controller 61. The controller 61 calculates the power generation capacity (corresponding to the actual operating capacity) of the unit 16 based on the input power generation amount of the power generation unit 16. Specifically, the controller 61 calculates the amount of power generation per unit time in the unit 16 every predetermined time, that is, the generated power as the power generation capacity. The controller 61 associates the calculated (acquired) generated power of the power generation unit 16 with the outdoor temperature input from the outdoor temperature sensor 52 when the generated power is acquired, and stores it in the storage unit 66 each time. Therefore, the storage unit 66 stores the power generation history information (corresponding to the operation history) related to when and how much power is generated by the power generation unit 16 in association with the outdoor temperature history.

  The power consumption of the air conditioner 31 is sequentially input from the air conditioning watt-hour meter 37 to the controller 61. The controller 61 calculates the heating capacity (corresponding to the actual operation capacity) of the air conditioner 31 based on the input power consumption of the air conditioner 31. Specifically, the controller 61 calculates the power consumption per predetermined time of the air conditioner 31 required during the operation based on the power consumption of the air conditioner 31 input during the steady operation of the air conditioner 31 every predetermined time. Calculated as heating capacity. In other words, when compared with operating conditions in which the heating set temperature is the same, if the heating capacity is large, the power consumption for maintaining the set temperature decreases. Conversely, if the heating capacity is small, the power consumption increases. . Therefore, it can be determined that the heating capacity of the air conditioner 31 is higher as the power consumption per predetermined time of the air conditioner 31 is smaller during the steady operation.

  Note that whether or not the air conditioner 31 is in steady operation is determined by, for example, the difference between the temperature of the living room 19 and the set temperature of the air conditioner 31 based on the detection result of the room temperature sensor 51 and the set temperature of the air conditioner 31. Can be calculated based on whether or not the calculated temperature difference is within a predetermined range.

  The controller 61 calculates the power consumption per predetermined time of the air conditioner 31 calculated (acquired), the temperature of the room 19 input from the room temperature sensor 51 when the power consumption is acquired, and the power consumption. Is stored in the storage unit 66 in association with the outdoor temperature input from the outdoor temperature sensor 52. Therefore, in the storage unit 66, the power consumption history (corresponding to the operation history) regarding how much power is consumed in the air conditioner 31 during the steady operation is stored in the storage unit 66. And the outdoor temperature are stored in association with each other.

  The power consumption of the lighting device 32 is sequentially input from the lighting watt hour meter 38 to the controller 61. Based on the input power consumption of the lighting device 32, the controller 61 changes the lighting state of the device 32 in which power is consumed from the lighting state of the device 32 in which power is not consumed in the lighting device 32 in detail. When it transfers, it determines with the illuminating device 32 having been turned on. Then, when the lighting device 32 is turned on, the controller 61 determines the illuminance of the living room 19 before and after lighting based on the detection result from the illuminance sensor 54, that is, the illuminance of the living room 19 when the lighting device 32 is turned off and the lighting device. The illuminance of the living room 19 at the time of lighting 32 (corresponding to the actual operating capacity) is acquired, and the acquired illuminances are stored in the storage unit 66 in association with each other. Thereby, the illuminance of the living room 19 when the lighting device 32 is turned on is stored in the storage unit 66 in association with the original illuminance of the living room 19 when the illuminance is acquired (illuminance when the lighting device 32 is turned off).

  The consumption of natural gas in the hot water supply facility 33 is sequentially input from the gas meter 46 to the controller 61. The controller 61 calculates the heating capacity (corresponding to the actual operation capacity) of the floor heating system 43 based on the gas consumption of the input hot water supply system 33. Specifically, the controller 61 has the gas consumption amount of the hot water supply facility 33 input when the temperature of the living room 19 is maintained at the target temperature (set temperature) by the heating operation by the floor heating facility 43 at predetermined time intervals. Based on the above, the gas consumption per predetermined time at the same stable time is calculated as the heating capacity. When the temperature is stable, the smaller the gas consumption of the hot water supply facility 33, the lower the natural gas, the more the natural temperature of the living room 19 can be maintained at the target temperature. Therefore, it can be determined that the heating capacity is high.

  Whether or not the living room 19 is at a stable temperature can be determined based on the detection result from the room temperature sensor 51, for example.

  The controller 61 calculates the gas consumption per predetermined time of the hot water supply facility 33 calculated (acquired), the temperature of the room 19 input from the room temperature sensor 51 when the gas consumption is acquired, and the gas consumption. Is stored in the storage unit 66 in association with the outdoor temperature input from the outdoor temperature sensor 52. Therefore, in the storage unit 66, the gas consumption history (corresponding to the operation history) regarding how much natural gas is consumed in the facility 43 when the floor heating facility 43 is in a stable state is stored in the storage unit 66. And the outdoor temperature are stored in association with each other.

  The controller 61 performs a deterioration diagnosis of each of the devices 15, 16, 31 to 33 based on the operation history of each of the power supply devices 15 and 16 and each of the facility devices 31 to 33 stored in the storage unit 66. Based on the result of the deterioration diagnosis, the controller 61 performs operation control of each of the power supply devices 15 and 16 and each of the facility devices 31 to 33, or performs opening / closing control of the shut-off device 23.

  Next, device control processing executed by the controller 61 will be described with reference to FIG. FIG. 3 is a flowchart showing the device control process. Note that this processing is periodically executed, and is started, for example, when a start date and time set every month is reached. In the following description, it is assumed that this process is performed in winter.

  Note that this process does not necessarily have to be started with the start date and time as a trigger, and may be started with a start operation performed on the operation unit 62 by the user as a trigger. Further, user detection means (for example, a human sensor or the like) for detecting whether or not the user is at home in the building 10 is provided so that the processing is started when it is detected that the user is absent. Also good.

  As shown in FIG. 3, first, in step S <b> 11, an operation stop signal is output to each equipment device 31 to 33 to stop the operation of each equipment device 31 to 33. Specifically, it is determined whether or not each facility device 31 to 33 is currently operating, and the facility devices 31 to 33 determined to be operating are stopped.

  In step S12, a deterioration diagnosis process for the equipment 31 to 33 is performed. Specifically, a deterioration diagnosis process for the air conditioner 31, the lighting device 32, and the hot water supply facility 33 is performed. Therefore, first, the deterioration diagnosis process of the air conditioner 31 among the deterioration diagnosis processes of each of the equipment devices 31 to 33 will be specifically described based on the flowchart of FIG. FIG. 4 is a flowchart showing the deterioration diagnosis process of the air conditioner 31.

  As shown in FIG. 4, first, in step S <b> 31, a heating operation signal is output to the air conditioner 31 to start the heating operation of the air conditioner 31.

  In a succeeding step S32, it is determined whether or not the air conditioner 31 is in a steady operation. This determination calculates the temperature difference between the temperature of the living room 19 and the set temperature of the air conditioner 31 based on the detection result from the room temperature sensor 51 and the set temperature of the air conditioner 31, and the calculated temperature difference is a predetermined value. It is based on whether or not it is within the range. If the air conditioner 31 is in steady operation, the process proceeds to step S33. If the air conditioner 31 is not in steady operation, that is, if it is in transient operation, the air conditioner 31 is in steady operation. Repeat this step until the transition. The set temperature of the air conditioner 31 is stored in the storage unit 66 in advance.

  In step S <b> 33, the current power consumption per unit time (current data of power consumption) of the air conditioner 31 is calculated (acquired) based on the measurement result from the air conditioning watt-hour meter 37. In the next step S34, the current room temperature and the outdoor temperature are acquired based on the detection results from the room temperature sensor 51 and the outdoor temperature sensor 52.

  In step S35, an extraction process is performed. In this process, the power consumption per unit time (past data) when the room temperature is the same as the current room temperature and the same outdoor temperature as the current outdoor temperature, that is, the current air conditioner 31 is installed. The power consumption per predetermined time when the environment (specifically, the installation temperature environment) is the same environment is extracted from the storage unit 66. When past data in the same environment as the current installation environment is not stored in the storage unit 66, data corresponding to the installation environment is calculated by linear interpolation or the like.

  In step S36, deterioration diagnosis of the air conditioner 31 is performed. When the air conditioner 31 deteriorates, it is conceivable that the heating efficiency (energy efficiency) decreases and the power consumption per unit time increases. Here, it is considered that the power consumption per unit time of the air conditioner 31 not only fluctuates (increases) due to deterioration of the air conditioner 31 but also varies depending on the temperature of the room 19 to be air-conditioned and the outdoor temperature. . Therefore, in the deterioration diagnosis of the air conditioner 31, paying attention to this point, the past data of the power consumption per predetermined time extracted (or calculated) in step S35 and the power consumption per predetermined time acquired in step S33. The deterioration data of the air conditioner 31 is diagnosed by comparing the current data. That is, in this process, the conditions of the room temperature and the outdoor temperature are unified, and the current power consumption per predetermined time is compared with the power consumption per predetermined time in the past. In this deterioration diagnosis, when the current power consumption per predetermined time has increased from that in the past, specifically, when the air consumption has increased by a predetermined amount or more, the air conditioner 31 has deteriorated. Is considered to be.

  In step S <b> 37, an operation stop signal is output to the air conditioner 31 to stop the heating operation of the air conditioner 31. Thereafter, this process is terminated.

  Returning to the description of FIG. 3, the deterioration diagnosis process of the equipment devices 32 and 33 other than the air conditioner 31 in step S <b> 12 will be described. First, the deterioration diagnosis of the lighting device 32 will be described. When the lighting device 32 deteriorates, the illuminance thereof, in other words, the illuminance of the living room 19 when the lighting device 32 is turned on is considered to decrease. Here, it is considered that the illuminance of the living room 19 when the lighting device 32 is turned on varies not only due to deterioration of the lighting device 32 but also depends on the illuminance of the living room 19 when the lighting device 32 is turned off. It is done. Therefore, in the deterioration diagnosis of the lighting device 32, paying attention to this point, first, based on the detection result from the illuminance sensor 54, the current illuminance of the living room 19, that is, the current illuminance in the state where the lighting device 32 is turned off. To get. Next, a lighting signal is output to the lighting device 32 to turn on the lighting device 32, and the current room illuminance (current data) in the lighting state is acquired from the illuminance sensor 54. Then, when the room illuminance at the time of turn-off is the same as the current room illuminance at the time of turn-off, the room illuminance at the time of lighting (past data) is extracted from the storage unit 66, and the extracted past data and current data are compared. Then, deterioration diagnosis of the illumination device 32 is performed. That is, in this process, the illuminance conditions of the room 19 at the time of turning off are standardized, and the current room illuminance at the time of lighting is compared with the past room illuminance at the time of lighting. In the present deterioration diagnosis, when the current room illuminance is lower than the past room illuminance, specifically, when the lighting device 32 is lower than a predetermined level, the illumination device 32 is regarded as deteriorated.

  Next, the deterioration diagnosis process of the hot water supply facility 33 will be described. When the hot water supply equipment 33 (including the floor heating equipment 43) deteriorates, it is conceivable that the heating efficiency (energy efficiency) of the equipment 33 decreases and the gas consumption per unit time increases. Here, it is considered that the gas consumption per unit time of the hot water supply facility 33 not only fluctuates (increases) due to deterioration of the hot water supply facility 33 but also varies depending on the room temperature and the outdoor temperature. Therefore, in the deterioration diagnosis of the hot water supply facility 33, the following processing is performed by paying attention to this point. First, an operation signal is output to the hot water supply facility 33 to start the operation of the hot water supply facility 33, and the heating operation by the floor heating facility 43 is started. After the start of operation, when the temperature of the living room 19 reaches the target temperature and shifts to a stable temperature, based on the measurement result from the gas meter 46, the current gas consumption per predetermined time of the hot water supply equipment 33 (of the gas consumption) Current data) is calculated (acquired), and the current room temperature and outdoor temperature are acquired based on the detection results from the room temperature sensor 51 and the outdoor temperature sensor 52. Then, the gas consumption per unit time in the past (past data) when the room temperature is the same as the current room temperature and the same outdoor temperature as the current outdoor temperature is extracted from the storage unit 66, The extracted past data and the acquired current data are compared to diagnose deterioration of the hot water supply equipment 33. That is, in this process, the conditions of the room temperature and the outdoor temperature are unified, and the current gas consumption per predetermined time is compared with the gas consumption per predetermined time in the past to perform deterioration diagnosis. And in this deterioration diagnosis, when the current gas consumption per predetermined time has increased from the past, specifically, when it has increased more than a predetermined amount, the hot water supply equipment 33 has deteriorated. It is supposed to be considered.

  In this deterioration diagnosis, since the heating operation of the air conditioner 31 is stopped, the deterioration diagnosis of the hot water supply facility 33 can be performed without considering the influence of heating by the air conditioner 31.

  In step S13, deterioration diagnosis processing for the power supply devices 15 and 16, that is, deterioration diagnosis processing for the solar panel 15 and the power generation unit 16 is performed. First, the deterioration diagnosis process of the solar panel 15 will be described. It is considered that the generated power decreases when the solar panel 15 deteriorates. Here, it is considered that the generated power of the solar panel 15 not only fluctuates (decreases) due to deterioration of the panel 15 but also fluctuates depending on the amount of solar radiation. Therefore, in the deterioration diagnosis of the solar panel 15, paying attention to this point, first, based on the measurement result from the panel watt hour meter 35, the current generated power of the solar panel 15 (current data of the generated power) is calculated ( And the current amount of solar radiation is acquired based on the detection result from the solar radiation amount sensor 53. And the past generation electric power (past data) when it is the same solar radiation amount as the present solar radiation amount is extracted from the memory | storage part 66, The extracted past data and the said acquired current data are compared, and sunlight is obtained. Diagnose the panel 15 for deterioration. That is, in this process, the conditions of the amount of solar radiation are unified and the present generated power is compared with the past generated power. And by this comparison, when the present generated electric power is lower than the past generated electric power, specifically, the solar panel 15 is considered to be deteriorated when it is lower than a predetermined amount or more.

  Next, the deterioration diagnosis process of the power generation unit 16 will be described. It is conceivable that the generated power decreases when the power generation unit 16 deteriorates. Here, the generated power of the power generation unit 16 not only fluctuates (decreases) due to deterioration of the unit 16, but also varies depending on the installation environment temperature where the power generation unit 16 is installed, that is, depending on the outdoor temperature. Conceivable. In view of this, the deterioration diagnosis of the power generation unit 16 pays attention to this point, and first calculates (acquires) the generated power (current data of generated power) of the current power generation unit 16 based on the measurement result from the unit watt-hour meter 36. At the same time, the current outdoor temperature is acquired based on the detection result from the outdoor temperature sensor 52. Then, past generated power (past data) when the outdoor temperature is the same as the current outdoor temperature is extracted from the storage unit 66, and the extracted past data is compared with the acquired current data to generate a power generation unit. 16 deterioration diagnosis is performed. That is, in this process, the conditions of the outdoor temperature are unified and the current generated power and the past generated power are compared. And by this comparison, when the present generated electric power is lower than the past generated electric power, specifically, when it is lower than the predetermined amount, the electric power generation unit 16 is regarded as deteriorated.

  In performing the deterioration diagnosis process of the power generation unit 16, if the power generation unit 16 is not in operation, the power generation unit 16 is first operated and then the deterioration diagnosis process of the unit 16 is performed.

  In addition, in the deterioration diagnosis process of each of the equipment devices 31 to 33 and each of the power supply devices 15 and 16 in step S12 and step S13, the determination as to whether or not the current installation environment of the device is the same as the past installation environment is as follows: For example, in the case of a temperature environment, it is desirable to carry out with a predetermined width (the same equivalent width) such as a width of 1 ° C.

  In step S14, a notification process for notifying the user of the result of the deterioration diagnosis process in each of steps S12 and S13 is performed. In this processing, the result of the deterioration diagnosis (presence / absence of deterioration, degree of deterioration, etc.) is displayed on the display unit 63 for notification. For example, when no deterioration is observed in any of the power supply devices 15 and 16 and each of the equipment devices 31 to 33, messages such as “no deterioration” and “no abnormality” are displayed on the display unit 63. In addition, if any of the devices is deteriorated, “the power generation efficiency of the solar panel is reduced.” “It is time to replace the lighting device 32.” “the cooling efficiency of the air conditioner is reduced by 15%” Etc. are displayed. Thereby, since the user can know the deterioration status of each of the power supply devices 15 and 16 and each of the facility devices 31 to 33, the user can take appropriate measures such as performing maintenance.

  Note that the notification process is not necessarily limited to the method of displaying the result of the deterioration diagnosis on the display unit 63. For example, the controller 61 may be provided with a communication function that enables communication with a mobile device carried by the user, and the result of the deterioration diagnosis process may be transmitted to the user's mobile device.

  Further, as a result of the deterioration diagnosis, when it is diagnosed that any one of the power supply devices 15 and 16 and each of the facility devices 31 to 33 is deteriorated, a notification process for notifying the fact by the notification unit 64 is performed. Also good. As the notification process, for example, an alarm sound may be output from the notification unit 64, or a sound such as “the cooling efficiency of the air conditioner has decreased” may be output. As a result, when the devices 15, 16, 31 to 33 are deteriorated, it is possible to prompt the user to perform maintenance or the like.

  In step S15, based on the result of the deterioration diagnosis of each equipment device 31 to 33 in steps S12 and S13, it is determined whether or not any of the equipment devices 31 to 33 has deteriorated. If none of the facility devices 31 to 33 has deteriorated, the process proceeds to step S17, and if any of the facility devices 31 to 33 has deteriorated, the process proceeds to step S16.

  In step S16, an operation restriction process is executed. When the equipment 31 to 33 is operated in a state where the deterioration has progressed, inconveniences such as increase in energy consumption and shortening the life of the equipment 31 to 33 by accelerating the progress of the deterioration compared to before the deterioration. There is a fear. Therefore, in this step, operation restriction is performed on the equipment 31 to 33 diagnosed as having deteriorated. Specifically, for example, when the air conditioner 31 is deteriorated, a process of limiting the heating load (operating load) of the air conditioner 31 is performed so that the temperature of the living room 19 does not exceed a predetermined temperature. Further, when the lighting device 32 is deteriorated, a process for limiting the lighting time is performed, for example, the lighting time (operation time) of the lighting device 32 in one day is set to 8 hours. Thereby, since said inconvenience can be suppressed, it is preferable from a viewpoint of energy saving or long life.

  When the air conditioner 31 is deteriorated, the operation of the air conditioner 31 may be prohibited, and the hot water supply facility 33 may be operated instead to heat the living room 19 with the floor heating facility 43. On the contrary, when the hot water supply facility 33 is deteriorated, the operation of the hot water supply facility 33 may be prohibited and the air conditioner 31 may be operated instead to heat the living room 19. If it does so, since use of the air conditioner 31 whose power consumption per unit time (in other words, energy efficiency) is increasing by deterioration can be avoided, it is preferable from the viewpoint of energy efficiency.

  In step S17, it is determined whether or not the power generation unit 16 has deteriorated based on the result of the deterioration diagnosis of the power generation unit 16 in step S13. If the power generation unit 16 has not deteriorated, the present process is terminated. If the power generation unit 16 has deteriorated, the process proceeds to step S18.

  In step S18, priority power supply processing is performed in which power is supplied to the power storage device 18 with priority from the commercial power system over the power generation unit 16 in a degraded state. In this process, when power is supplied to the power storage device 18, power is supplied from the commercial power system to the power storage device 18 with the shut-off device 23 in a closed state (energized state). The generated power is constantly supplied to the power storage device 18.) The operation of the power generation unit 16 is stopped and the power supply from the power generation unit 16 to the power storage device 18 is stopped. And only when power supply from the commercial power system and the solar panel 15 cannot store the target power amount in the power storage device 18 within a predetermined time (for example, when it is raining and power generation by the solar panel 15 is impossible) ), The power generation unit 16 is operated, and the power supply from the power generation unit 16 is performed. Thereby, since the operation rate of the power generation unit 16 in which the deterioration has occurred can be reduced, the power generation unit 16 can be made to last, and as a result, the power supply devices 15 and 16 can be made to last longer. In addition, by giving priority to power supply from the commercial power system, it is possible to reduce the frequency of use of the power generation unit 16 whose power generation efficiency has decreased due to deterioration in performance, and thus an energy saving effect can be expected. Thereafter, this process is terminated.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  The operation status of the acquired devices 15, 16, 31 to 33 is stored in the storage unit 66 as an operation history together with the installation environment information of the devices 15, 16, 31 to 33 acquired at the time of acquisition of the operation status. Based on the operation history, deterioration diagnosis of the devices 15, 16, 31 to 33 was performed. As a result, the deterioration diagnosis is performed based on the installation environment of the devices 15, 16, 31 to 33 in addition to the operation status of the devices 15, 16, 31 to 33. For example, when the installation environment is extremely high, the progress of the deterioration Thus, it is possible to perform a deterioration diagnosis taking into account the installation environment of the devices 15, 16, 31 to 33, such as diagnosing that the vehicle is moving relatively quickly. Thereby, the deterioration diagnosis of apparatus 15,16,31-33 can be performed suitably.

  Specifically, the actual operating capacity of the calculated (acquired) devices 15, 16, 31 to 33 and the installation environment of the devices 15, 16, 31 to 33 acquired when acquiring the actual operating capability are stored in the storage unit 66. Are stored in association with each other. Then, the actual operating capacity of the devices 15, 16, 31 to 33 in the past installation environment that is the same or substantially the same as the current installation environment of the devices 15, 16, 31 to 33 is extracted from the storage unit 66, and the extracted Deterioration diagnosis of the devices 15, 16, 31 to 33 was performed by comparing the past actual operation capability of the devices 15, 16, 31 to 33 with the current actual operation capability. According to this, it is possible to compare the actual operating capability of the current devices 15, 16, 31 to 33 with the past actual operating capability under the same conditions of the installation environment of the devices 15, 16, 31 to 33. Therefore, when a decrease in operating capacity is observed in the devices 15, 16, 31 to 33, it can be determined that the decrease is not due to a change in the installation environment, and as a result, a deterioration diagnosis of the devices 15, 16, 31 to 33 is performed. It can carry out still more suitably. Further, in this case, since the criterion for deterioration determination is set according to the past operation status, deterioration determination conforming to actual operation can be performed for each device.

  For the air conditioner 31, the room temperature sensor 51 and the outdoor temperature are acquired in the storage unit 66 when the acquired power consumption (actual operating capacity) per predetermined time of the air conditioner 31 and the power consumption per predetermined time are acquired. The temperature of the room 19 and the outdoor temperature acquired by the sensor 52 are associated and stored as an operation history, and the deterioration diagnosis of the air conditioner 31 is performed based on the operation history of the air conditioner 31. In this case, when the increase in the power consumption per predetermined time in the air conditioner 31 is expressed in other words, when the heating capacity of the air conditioner 31 is reduced, is it due to the deterioration of the air conditioner 31 or the temperature of the living room 19? Or it becomes possible to judge whether it is based on the fluctuation | variation of outdoor temperature, As a result, the deterioration diagnosis of the air conditioner 31 can be performed suitably.

  As a temperature control device that adjusts the temperature of the living room 19, a plurality of temperature control devices that use different energies as operating sources, specifically, an air conditioner 31 that operates by electric power and a hot water supply facility 33 that operates by natural gas (floor Heating equipment 43) is provided, and based on the result of deterioration diagnosis of each of the temperature control devices 31, 33, it is determined which of the temperature control devices 31, 33 is to be operated. Thereby, since it is possible to avoid the use of the temperature control devices 31 and 33 whose energy efficiency is reduced due to deterioration, it can be said that it is preferable from the viewpoint of energy efficiency.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, the system for diagnosing device deterioration has been described. However, a function for controlling the environment of the living room 19 may be further added to the above system. Specifically, based on the operation history for the equipment devices 31 to 33 by the user (that is, a resident in the building 10), the user's behavior is predicted, and the operation of each equipment device 31 to 33 is controlled based on the prediction result. It is possible. Hereinafter, a specific example thereof will be described with reference to FIG. In this example, the description will focus on differences from the configuration of the above embodiment.

  The operation unit 62 is provided with an air conditioning switch 71, an illumination switch 72, and a hot water supply switch 73. The air conditioning switch 71 is an on / off operation of the air conditioner 31 and a target temperature setting. When the switch 71 is operated, operation information corresponding to the operation is sequentially transmitted from the operation unit 62 to the controller. 61 is input. The illumination switch 72 is a switch for performing ON / OFF operation of the illumination device 32. When the switch 72 is operated ON / OFF, operation information corresponding to the operation is sequentially transmitted from the operation unit 62 to the controller 61. Entered. The hot water supply switch 73 is a switch for performing an ON / OFF operation of the hot water supply facility 33. When the switch 73 is operated, operation information corresponding to the operation is sequentially input from the operation unit 62 to the controller 61. . In this example, when the hot water supply switch 73 is turned ON, operation of the hot water supply facility 33 is started and hot water supply from the hot water supply facility 33 to the bathtub is also started.

  A room communication unit 74 is connected to the input side of the controller 61. The living room communication unit 74 can communicate with the portable device 75 carried by the user, and is provided on the wall surface of the living room 19. Specifically, the room communication unit 74 can communicate with the portable device 75 using a range including at least the room 19 as a communication area.

  Here, the portable device 75 is constituted by a mobile phone, for example. The portable device 75 has a communication function for communicating with the communication unit on the building 10 side, and a storage function for storing an ID code as identification information. In the present embodiment, an ID code unique to the device (that is, user-specific) is stored in the portable device 75 in advance. In addition, when the building 10 is provided with the locking / unlocking system that locks and unlocks the front door using the electronic key, the portable device 75 may be configured with the electronic key.

  When any one of the switches 71 to 73 of the operation unit 62 is operated by the user and an operation signal corresponding to the operation is input from the operation unit 62 to the controller 61, the controller 61 sends a request signal from the room communication unit 74. Send. When this request signal is received by the portable device 75 of the user, the portable device 75 transmits an ID code signal as a response. When the controller 61 receives the ID code signal through the room communication unit 74, the controller 61 determines the user based on the received ID code, and associates the determined user with each of the input equipment devices 31-33. The operation information for either one is stored in the storage unit 66. At this time, the controller 61 stores the operation information of the equipment devices 31 to 33 in the storage unit 66 in association with the current date and time. Thereby, the operation history regarding when and which user operated which equipment 31 to 33 can be grasped.

  A biosensor 77 is connected to the input side of the controller 61. The living body sensor 77 is composed of, for example, a toilet seat sensor provided in a toilet seat of a toilet, and is configured to detect the user's biological information when a part of the user's body contacts the toilet seat. Specifically, the biological sensor 77 detects body temperature, the number of times of sneezing and coughing, etc. as biological information. The biological sensor 77 can be embodied as other than the toilet seat sensor. The detection results are sequentially input from the biological sensor 77 to the controller 61.

  A biometric communication unit 78 is connected to the input side of the controller 61. The biometric communication unit 78 is provided in the vicinity of the biometric sensor 77, and is specifically installed in a toilet. The biometric communication unit 78 can communicate with a portable device 75 carried by the user. Specifically, the biometric communication unit 78 can communicate with the portable device 75 using a range including at least a toilet as a communication area.

  When the detection result is input from the biological sensor 77, the controller 61 transmits a request signal from the biological communication unit 78 to the toilet. When this request signal is received by the portable device 75 of the user, the portable device 75 transmits an ID code as a response. When the ID information is received by the controller 61 through the biometric communication unit 78, the controller 61 determines the user based on the received ID code, and stores the detected biometric information in the storage unit 66 in association with the determined user. To do. Thereby, each user's biometric information can be grasped.

  Next, the contents of various controls executed by the controller 61 will be described. First, environmental control of the living room 19 will be described.

  The controller 61 performs user behavior prediction based on the operation history of each facility device 31 to 33 stored in the storage unit 66, and executes operation control of each facility device 31 to 33 based on the result of the behavior prediction. To do. For example, in the case where the history of the user turning on the air conditioner 31 at 19:00 immediately after returning home is stored in the storage unit 66, the air conditioner 31 is operated at 19:00 or before 19:00. It is conceivable to control as follows. In addition, even when the setting temperature of the air conditioner 31 is set to 20 ° C. and the history of the user changing the set temperature of the air conditioner 31 to 25 ° C. is stored in the storage unit 66, It is conceivable to control the operation of the air conditioner 31 so that the temperature of the living room 19 becomes 25 ° C. Therefore, in this case, the environment in the living room 19 can be controlled according to the user's behavior, which is convenient for the user.

  In addition, the controller 61 performs operation control of each of the equipment devices 31 to 33 based on the user's biological information stored in the storage unit 66. In this case, when the user has a cold, the temperature in the room 19 can be set higher than usual, for example, so that the interior of the room 19 can be set in an environment according to the physical condition of the user. In addition, when the user has a cold, advice such as “please go to bed early” may be given from the notification unit 64.

  Furthermore, when the user performs an action different from the predicted user action, the controller 61 may notify the effect from the notification unit 64. For example, the controller 61 predicts that the user will take a bath from 21:00 based on the operation history of the hot water supply facility 33 by the user stored in the storage unit 66, so that the hot water to the bathtub is finished at 21:00. If the user determines that he / she is still in the room 19 after 21:00 despite controlling the hot water supply facility 33, advice such as “please take a bath” may be given from the notification unit 64. . In this way, the user can be encouraged to take a bath, and the hot water in the bathtub can be avoided from being unnecessarily cooled. The determination that the user is in the living room 19 can be made based on the fact that the ID code signal from the portable device 75 is received by the controller 61 through the living room communication unit 74.

  Next, the operation restriction prohibiting process will be described.

  Based on the user's biological information stored in the storage unit 66, the controller 61 determines whether or not the temperature adjustment of the living room 19 is required due to the operation of the air conditioner 31. Even when the air conditioner 31 is deteriorated, the air conditioner 31 is controlled so as not to perform the operation restriction (step S16 in FIG. 3) (operation restriction prohibition process). In other words, in the above embodiment, when the air conditioner 31 is deteriorated, the operation restriction is uniformly performed on the air conditioner 31. However, in this example, even if the air conditioner 31 is deteriorated, the biometric information of the user is used. If it is determined that the temperature adjustment by the operation of the air conditioner 31 is required, the operation restriction on the air conditioner 31 is not performed. Therefore, for example, when the user has a cold, even if the air conditioner 31 is deteriorated, the heating operation can be performed without restricting the operation of the air conditioner 31, and the living room 19 can be warmed. Therefore, when the air conditioner 31 is deteriorated, it becomes possible to use the air conditioner 31 giving priority to the user's physical condition. In addition, when it is determined that the temperature adjustment by the operation of the air conditioner 31 is necessary based on the user's biological information during the operation restriction process for the air conditioner 31, the operation restriction of the air conditioner 31 is temporarily set. Control to release.

  In addition, when the building 10 is provided with a humidifier (may be a mist generator) as equipment to adjust the humidity of the living room 19, and the humidifier is a control target of this system, Operation restriction prohibition processing may be performed. If it does so, even if the humidifier has deteriorated when the user has a cold, the humidification of the living room 19 can be performed by the humidifier without restricting the operation of the humidifier.

  (2) Instead of or in addition to the solar panel 15 and the power generation unit 16, an in-vehicle battery (high voltage battery) mounted on a hybrid vehicle may be used as the power supply device of the above embodiment. The hybrid vehicle has a generator, and the generator generates electricity by running the vehicle, and the generated electric power is charged in the in-vehicle battery. A hybrid vehicle (hereinafter referred to as a vehicle) is parked in a predetermined parking space adjacent to the building 10 and can be connected to the building 10 side via a connection power line. Can be supplied to the distribution board 11 and thus to the electrical equipment 31 and 32 through the connection power line.

  In addition, the building 10 is provided with a shut-off device that permits and shuts off the power supply from the in-vehicle battery to the distribution board 11 in the connection state by the connection power line. The shut-off device is built in the distribution board 11, for example. The shut-off device is connected to the controller 61 and is controlled to open and close based on a control command from the controller 61. In this case, battery power is supplied from the vehicle-mounted battery to the electrical equipment devices 31 and 32 by closing the shut-off device. For this reason, battery power is originally used for driving a car, but it can be used as the power supply devices 15 and 16 as described above to supply power to the electrical equipment devices 31 and 32 at a low cost. It becomes.

  Here, as described above, in this example, since the vehicle-mounted battery is used as an energy source for driving the automobile and is also used as a power supply source for the electric equipment 31 and 32, there are a plurality of users who use the automobile. When a certain user plans to go out using a car, other users try to operate the air conditioner 31 using the battery power of the in-vehicle battery, and multiple users use the in-vehicle battery for different purposes. A situation to try can occur. Accordingly, in view of this point, when a plurality of users make different usage requests for the in-vehicle battery to the operation unit 62, any user's request is made based on the usage history of the in-vehicle battery of each user. It is conceivable to determine whether to give priority and control power supply from the in-vehicle battery to the power equipment 31 and 32 based on the determination.

  Specifically, the automobile of this example has a monitoring function for monitoring the amount of electricity stored in the in-vehicle battery and a communication function for performing communication with the building 10 side. The stored amount of the in-vehicle battery is sequentially transmitted from the automobile to the controller 61 on the building 10 side by radio or the like, and the stored amount of the in-vehicle battery can be grasped on the building 10 (controller 61) side. In addition, the building 10 is provided with a connection detection sensor that detects that the automobile is connected to the building 10 side via the connection power line, and the detection result of the sensor is sequentially input to the controller 61. . The controller 61 determines whether the automobile is parked in the parking lot adjacent to the building 10 or is running based on the detection result from the connection detection sensor. Then, when the controller 61 confirms a change in the storage amount of the in-vehicle battery (change to the decrease side) when the automobile is parked in the parking lot, the in-vehicle battery supplies power to the electrical equipment devices 31 and 32. On the other hand, when it is determined that the amount of stored power of the in-vehicle battery is changed while the automobile is running, it is determined that the in-vehicle battery is used as an energy source for running the automobile. . When the controller 61 determines that the in-vehicle battery is used for either the power supply to the electrical equipment 31 and 32 or the energy source for driving the automobile, the in-vehicle battery usage information is stored in the storage unit 66 each time. Remember. As a result, the storage unit 66 stores a use history regarding when and when the in-vehicle battery was used. Further, in this example, it is assumed that the user A uses the in-vehicle battery for driving the automobile, and the user B uses the in-vehicle battery for power supply to the electrical equipment 31 and 32. Therefore, it is possible to grasp the usage history of the in-vehicle battery by the user A and the user B.

  Next, priority control processing executed by the controller 61 will be described based on the flowchart of FIG. In the following description, it is assumed that there are different usage requests for the in-vehicle battery by the user A and the user B, using the same day as the scheduled use date, for example, Wednesday May 21st. Note that this process is triggered by the fact that the predetermined time on Wednesday is reached.

  First, in step S51, it is determined whether or not the use schedule of the in-vehicle battery has been canceled by the former by the day before the scheduled use date of the in-vehicle battery (May 20). This determination is made based on whether or not a release operation has been performed by the former through the operation unit 62. When the use of the in-vehicle battery is canceled by the former, the process proceeds to step S55, and when there is no use cancellation, the process proceeds to step S52.

  In step S52, it is determined whether or not the use schedule of the in-vehicle battery has been canceled by the end of the day before the scheduled use date of the in-vehicle battery (May 20). This determination is made based on whether or not a cancel operation has been performed by the user through the operation unit 62. If the use of the in-vehicle battery is canceled by the second party, the process proceeds to step S54. If the use is not canceled, the process proceeds to step S53.

  In step S53, the in-vehicle battery usage history and the usage history by the second party on Wednesday are read out from the storage unit 66, and on the Wednesday, the first party is in-vehicle than the second party on the basis of the read first and second usage history. It is determined whether or not the battery usage frequency (eg, usage time, usage count, etc.) is high. If the use frequency of the in-vehicle battery is higher than that of the second party, the process proceeds to step S54, and if the use frequency of the first is not higher than that of the second party, the process proceeds to step S55.

  In step S54, when it is Wednesday, the power supply process for the electric equipment 31 and 32 is prohibited based on the request of the former. In this process, the shut-off device is closed and power supply from the in-vehicle battery to the electric equipment 31 and 32 is prohibited. In this case, since the battery power of the in-vehicle battery is maintained without being used, the former can use the battery power for driving the vehicle on Wednesday. Thereafter, this process is terminated.

  In step S55, when it is Wednesday, power supply processing is performed on the electrical equipment 31 and 32 based on the request of the second party. In this process, at the time of power supply designated by the second party, the shut-off device is closed and power supply from the in-vehicle battery to the electrical equipment devices 31 and 32 is started. Thereafter, this process is terminated.

  According to the said structure, when there exists a usage request by the some user with respect to a vehicle-mounted battery, use of a vehicle-mounted battery is permitted only to a user with high use frequency. Therefore, it is convenient for a user who frequently uses an in-vehicle battery because the use of the battery can be secured.

  (3) The deterioration of the device proceeds according to the amount of operation of the device (specifically, the total amount of operation). The progress of deterioration is considered to change depending on the installation environment of the device (for example, temperature environment or humidity environment). Therefore, paying attention to this point, device deterioration diagnosis may be performed as follows. That is, an acquisition unit that acquires the operation amount of the device every predetermined time during operation of the device is provided, and the acquired operation amount is stored in the storage unit 66 as an operation history together with the installation environment acquired by the installation environment acquisition unit at the time of acquisition. Remember. Then, setting means for setting the deterioration coefficient based on the installation environment corresponding to each operation amount for each operation amount stored in the storage unit 66, and the product of each operation amount and the deterioration coefficient for each operation amount. An integration unit that calculates and integrates the calculated products is provided, and deterioration diagnosis is performed based on the integrated value integrated by the integration unit. Hereinafter, a specific example of this will be described by taking deterioration diagnosis of the power generation unit 16 as an example.

  In this example, the controller 61 acquires a power generation amount per predetermined time (hereinafter referred to as a unit time power generation amount) of the power generation unit 16 based on the measurement result from the unit watt-hour meter 36, and the acquired The unit time power generation amount and the outdoor temperature acquired from the outdoor temperature sensor 52 when the unit time power generation amount is acquired are stored in the storage unit 66 in association with each other. The storage unit 66 stores in advance a deterioration coefficient α determined for each outdoor temperature. For example, map data indicating a correspondence relationship between the deterioration coefficient α and the outdoor temperature is stored. The deterioration coefficient α is a coefficient indicating the degree of deterioration of the power generation unit 16. The power generation unit 16 is considered to have a different degree of deterioration depending on whether the installation environment is normal temperature or a temperature lower or higher than that. Therefore, the deterioration coefficient α is higher when the outdoor temperature where the unit 16 is installed is a normal temperature (for example, 25 ° C.) or a value at a low temperature or a high temperature than a value at a predetermined normal temperature range including the normal temperature. For example, α = 1 at normal temperature or normal temperature range, and α> 1 at other times.

  The controller 61 sets the deterioration coefficient α for each unit time power generation amount stored in the storage unit 66 based on the outdoor temperature corresponding to each unit time power generation amount. Then, the controller 61 calculates the product of each unit time power generation amount and the set deterioration coefficient α for each unit time power generation amount, and integrates the calculated products. This integrated value is a value obtained by adding the degree of deterioration according to the installation environment of the unit 16 to the total power generation amount (total operating amount) of the power generation unit 16, and the controller 61 performs the deterioration diagnosis based on this integrated value. . Specifically, the deterioration diagnosis is performed based on whether or not the integrated value is larger than a predetermined deterioration determination value. Thereby, even if the total power generation amount of the power generation unit 16 is the same, the deterioration is progressing faster as the installation environment of the power generation unit 16 is often higher or lower than the normal temperature or the normal temperature range. As a result, it is possible to perform a deterioration diagnosis in consideration of the installation environment of the devices 15, 16, 31 to 33. Therefore, the deterioration diagnosis of the devices 15, 16, 31 to 33 can be suitably performed.

  (4) In the above embodiment, based on the result of deterioration diagnosis of the power supply device (specifically, the power generation unit 16), the electric facility device (details) gives priority to power from either the power supply device or the commercial power system. However, the air conditioner 31 and the lighting device 32) may be changed. For example, in a device control system that controls a plurality of power supply devices, based on the result of deterioration diagnosis of each power supply device, power from any of the power supply devices is preferentially supplied to electrical equipment. You may decide. For example, when a plurality of power generation units 16 are provided in the system of the above-described embodiment and power supply from each of the power generation units 16 to the power storage device 18 is enabled, any power generation unit 16 is determined based on the deterioration diagnosis result of each power generation unit 16. It is conceivable to decide whether to supply power to the power storage device 18 with priority. In this case, when any one of the power generation units 16 is deteriorated, power can be supplied to the power storage device 18 with priority from the other power generation unit 16. Therefore, the operating load of the deteriorated power generation unit 16 can be reduced, and the unit 16 can be prolonged.

  (5) The device control system of the above-described embodiment performs the deterioration diagnosis using both the power supply devices 15 and 16 and the facility devices 31 to 33 as diagnosis targets. , 16 and the equipment 31 to 33 may be subjected to a deterioration diagnosis. Further, only one of the plurality of power supply devices 15 and 16 may be a diagnosis target, or only one of the plurality of facility devices 31 to 33 may be a diagnosis target.

  (6) In the above embodiment, the device control process (the process of FIG. 3) is started when triggered by the start date and time set regularly (every month). It is also assumed that the same installation environment data as the installation environment of the devices 15, 16, 31 to 33 is not stored in the storage unit 66. In that case, the deterioration diagnosis cannot be performed at the time of the processing, which is inconvenient. Therefore, when the devices 15, 16, 31 to 33 are in operation, the device includes a verification means for verifying the current installation environment of the device and the past installation environment stored in the storage unit 66. When the same installation environment data is stored in the storage unit 66, the deterioration diagnosis process may be started. This is convenient because the present processing is started at the timing when the current operating capacity can be compared with the past operating capacity under the same installation environment conditions, that is, when the deterioration diagnosis is possible. .

  (7) The power generated by the device control system of the above embodiment may be sold. For example, it is conceivable to use a configuration in which the generated power stored in the power storage device 18 is sold. Specifically, a power line for supplying power from the power storage device 18 to the commercial power system is provided, and a CT sensor that detects the amount of power flowing through the power line on the power line, that is, the amount of power sold to the outside. Provide. Then, the CT sensor is connected to a monitor (which may be the display unit 63) via a communication cable, so that the amount of power sold detected by the CT sensor can be monitored by the monitor. In this case, the power sale status by this system can be easily grasped. Further, a power conditioner that converts DC power generated by the solar panel 15 into AC power may be connected to the monitor via a communication cable. If it does so, the operating condition of a power conditioner can be monitored with a monitor.
