Specifically, the gateway device 12 may be a high-performance distribution board having a simple home energy management system (HEMS: Home Energy Management System) function. As a result, compared to the case where the house 10 is provided with the gateway device 12 and the distribution board 13 as separate bodies, it is possible to reduce the cost and realize distribution and communication with the outside by each facility 17 installed in the house 10. Can be done.

The gateway device 12 may be HEMS. In this case, the HEMS may store the usage status data indicating the usage status of the equipment 17 transmitted from the equipment 17 via the concentrator 11 or output the usage status data to the input / output device 18. Further, the HEMS may communicate with the distribution board measurement unit 14 and the B route receivable device 16 provided in the house 10 via the line concentrator 11.

The distribution board measurement unit 14 may be arranged inside the distribution board 13 or may be arranged in the vicinity of the distribution board 13. When the distribution board measurement unit 14 is arranged inside the distribution board 13, it is aesthetically pleasing because it is not normally visible to a person in the house 10. Therefore, when the house 10 is newly constructed, the distribution board 13 is provided so as to arrange the distribution board measurement unit 14 inside in consideration of this point.

The smart meter 15 is installed outside the house 10 and on the site where the house 10 is constructed.

Equipment 17 is a device or device operated by the energy of electricity, gas, or water. Equipment 17 includes, for example, a gas water heater, an electric water heater, and an air conditioner. The equipment 17 may include a toilet, a gas stove, an electric stove, a power generation / storage device, and a water supply / drainage facility. The life of such equipment 17 is often shorter than the life of the house 10.

The equipment 17 includes a main body unit 171, an identifier storage unit 172, a detection unit 173, a characteristic value information storage unit 174, a determination unit 175, and an equipment communication unit 176.

The main body 171 operates by utilizing the energy of electricity, gas, or water. An example of the main body 171 will be described later.

The identifier storage unit 172 stores the equipment ID for identifying the equipment 17. The identifier storage unit 172 may store the house ID.

The detection unit 173 detects a characteristic value (hereinafter, referred to as “operation characteristic value”) of the main body unit 171 that changes with operation. An example of the operating characteristic value will be described later.

The characteristic value information storage unit 174 stores the operation characteristic value detected by the detection unit 173 together with the time when the operation characteristic value is detected.

The determination unit 175 determines whether or not the main body unit 171 is out of order by a known method. Further, the determination unit 175 determines the failure risk leading to the failure based on the operation characteristic value and the time stored in the characteristic value information storage unit 174.

In the present embodiment, "failure" is a state in which the main body 171 becomes unavailable. Specifically, the main body unit 171 is "failed" when the state set by the user or the state set at the time of manufacturing cannot be realized. For example, when the equipment 17 is a water heater, the main body 171 can be used if the water can be heated to the temperature set by the user, and cannot be used unless the water can be heated to the temperature. Is. For example, when the equipment 17 is an air conditioner, the main body 171 can be used if the room temperature can be adjusted to the temperature set by the user, and cannot be used unless the room temperature can be adjusted to the temperature. be.

Even if the main body 171 can be used, more energy than the design value may be consumed due to deterioration, defects, etc. of the parts constituting the main body 171. In such cases, the user may not be aware that the deteriorated part needs to be replaced or repaired. Therefore, the determination unit 175 determines the failure risk that is difficult for the user to recognize.

Here, the process of determining the failure risk by the determination unit 175 will be described in detail. The determination unit 175 determines the failure risk based on the degree to which the operating characteristic value deviates from the ideal value (hereinafter, referred to as “design value”) expected at the time of design. Specifically, the determination unit 175 determines that the ratio of the operating characteristic values whose difference from the design value is equal to or greater than the reference value among the plurality of operating characteristic values detected within a predetermined period (for example, one month) from the present. The higher the value, the higher the risk of failure. The failure risk is represented by, for example, a numerical value of 0 to 100%. The failure risk may be expressed by words such as "high possibility of failure" and "low possibility of failure". Further, the failure risk may be represented by, for example, a color such as a background color or a character color when displaying information indicating the failure risk on the input / output device 18.

In another example, the determination unit 175 sets the failure risk to the first value (when the ratio of the operation characteristic values whose difference from the design value is equal to or greater than the reference value is the first ratio or more among the plurality of operation characteristic values. For example, it is determined to be 70%). When the ratio of the operation characteristic values whose difference from the design value is equal to or more than the reference value is less than the first ratio and is equal to or more than the second ratio smaller than the first ratio among the plurality of operation characteristic values, the determination unit 175 determines. It is determined that the failure risk is a second value (for example, 50%) lower than the first value. Further, in the determination unit 175, when the ratio of the operation characteristic value in which the difference from the design value is equal to or more than the reference value is less than the second ratio among the plurality of operation characteristic values, the failure risk is lower than the second value. Determined to be a value (eg, 30%).

The determination unit 175 may estimate the failure prediction time based on the failure risk. For example, the determination unit 175 may determine that the higher the failure risk, the closer the failure prediction time is, based on the relationship between the failure risk and the failure prediction time predetermined in the statistics. The failure prediction time is expressed using the number of years, the number of months, the number of weeks, the number of days, etc., such as "within 1 year" and "within 6 months". Further, the determination unit 175 may determine the failure prediction time and the failure risk of failure by the failure prediction time based on the relationship predetermined by statistics or the like.

The equipment communication unit 176 is compatible with communication standards such as ECHONET Lite (registered trademark), and communicates with the gateway device 12 via the line concentrator 11. The equipment communication unit 176 transmits the failure information to the gateway device 12 via the line concentrator 11. The failure information includes the failure risk determined by the determination unit 175 and the equipment ID stored in the identifier storage unit 172. When the house ID is stored in the identifier storage unit 172, the failure information includes the house ID in addition to the failure risk and the equipment ID.

The gateway device 12 that has received the failure information transmits the failure information to the equipment management server 20. When the failure information includes only the failure risk and the equipment ID, the gateway device 12 further includes the house ID in the failure information and transmits the failure information to the equipment management server 20. When the failure information includes the failure risk, the equipment ID, and the housing ID, the gateway device 12 transmits the failure information received from the equipment 17 to the equipment management server 20 as it is. Therefore, the equipment management server 20 can associate a plurality of equipment 17 included in the house 10. This has a great advantage in centrally managing a wide variety of equipment 17.

Further, although it is assumed that the house 10 is provided with one or more facilities 17 in the above description, when the house 10 is provided with a plurality of facilities 17, the plurality of equipment communication units 176 of the plurality of facilities 17 each have one failure information. It is transmitted to the equipment management server 20 via the two gateway devices 12.

Hereinafter, the main body unit 171, the detection unit 173, the characteristic value information storage unit 174, and the determination unit 175 will be described in detail for each type of equipment 17. The determination unit 175 will be described in detail about the process of determining the failure risk.

(When the equipment is a gas water heater or a gas stove)
When the equipment 17 is a gas water heater or a gas stove, the main body 171 ignites the burner and rotates the combustion fan when a combustion command is input. In this example, the operating characteristic value is the number of ignitions until the burner starts combustion. Further, the operating characteristic value may be the rotation speed of the combustion fan.

The detection unit 173 detects the number of ignitions until the burner in the main body unit 171 starts combustion. Further, the detection unit 173 detects the rotation speed of the combustion fan in the main body unit 171.

The characteristic value information storage unit 174 stores the number of ignitions detected by the detection unit 173 together with the detection time. The detection time is the time when the number of ignitions until the burner starts combustion is detected in the main body 171, that is, the time when the burner starts combustion. Further, the characteristic value information storage unit 174 stores the rotation speed of the combustion fan detected by the detection unit 173 together with the detection time. The detection time is the time when the rotation speed of the combustion fan is detected.

The determination unit 175 determines the failure risk based on the number of ignitions and the detection time detected by the detection unit 173. Specifically, the determination unit 175 extracts the number of ignitions in which the detection time stored in the characteristic value information storage unit 174 is within a predetermined period (for example, one month) from the present. Then, for example, the determination unit 175 determines that the higher the ratio of the number of ignitions is equal to or greater than the reference value among the plurality of ignitions detected by the detection unit 173, the higher the risk of failure.

In another example, the determination unit 175 determines that the failure risk is the first value when the ratio of the difference from the design value to the design value is the first ratio or more among the plurality of ignition times. In the determination unit 175, when the ratio of the number of ignitions whose difference from the design value is equal to or greater than the reference value is less than the first ratio and greater than or equal to the second ratio smaller than the first ratio, the failure risk is higher. It is determined that the second value is lower than the first value. Further, the determination unit 175 determines that the failure risk is the third value lower than the second value when the ratio of the difference from the design value to the design value is less than the second ratio among the plurality of ignition times. do.

Further, the determination unit 175 determines the failure risk based on the rotation speed of the combustion fan detected by the detection unit 173. Specifically, the determination unit 175 extracts the number of rotations whose detection time stored in the characteristic value information storage unit 174 is within a predetermined period (for example, one month) from the present. Then, for example, among the plurality of rotation speeds detected by the detection unit 173, it is determined that the higher the ratio of the difference from the design value of the rotation speed is greater than or equal to the reference value, the higher the failure risk. In this case, the failure risk is represented by a numerical value of 0 to 100%.

In another example, the determination unit 175 determines that the failure risk is the first value when the ratio of the difference from the design value to the design value is the first ratio or more among the plurality of rotation speeds. The determination unit 175 has a first failure risk when the ratio of the difference from the design value to the design value is less than the first ratio and is smaller than the first ratio in the second ratio or more among the plurality of rotation speeds. It is determined that the second value is lower than the value. Further, the determination unit 175 determines that the failure risk is the third value lower than the second value when the ratio of the difference from the design value to the design value is less than the second ratio among the plurality of rotation speeds. judge. Here, the first ratio, the second ratio, the first value, the second value, and the third value are the first ratio, the second ratio, the first value, and the second value in the determination based on the number of ignitions described above, respectively. And the third value do not have to be the same.

(If the equipment is an electric water heater, air conditioner, electric stove, or toilet)
When the equipment 17 is any of an electric water heater, an air conditioner, an electric stove, or a toilet, the main body 171 changes the temperature of the controlled object to a desired temperature. When the equipment 17 is an electric water heater such as EcoCute (registered trademark), the controlled object is water. When the equipment 17 is an air conditioner, the controlled object is the air in the room where the air conditioner is installed. When the equipment 17 is an electric stove, the controlled object is a heating member included in the electric stove. When the equipment 17 is a toilet, the controlled object is the toilet seat of the toilet. When the equipment 17 is a toilet, the controlled object may be cleaning water supplied by the toilet.

For example, when the equipment 17 is an electric water heater, the main body 171 heats water by a known method. Specifically, the main body 171 heats water to a set temperature set by the user by using electric energy.

For example, when the equipment 17 is an air conditioner, the main body 171 changes the indoor temperature of the room in which the air conditioner is installed by a known method. Specifically, the main body 171 adjusts the room to a set temperature set by the user by using electric energy.

For example, when the equipment 17 is an electric stove, the main body 171 adjusts the temperature of the heating section of the main body 171 by a known method. Specifically, the main body unit 171 adjusts the heating unit to a set temperature set by the user by using electric energy.

For example, when the equipment 17 is a toilet, the main body 171 adjusts the temperature of the valve seat and the water supply temperature of the main body 171 by a known method. Specifically, the main body 171 adjusts the valve seat and the water supply to the set temperature set by the user by using electric energy.

The detection unit 173 detects the power efficiency, which is the amount of power consumption required for the equipment 17 to change the temperature of the non-controlled object to the unit temperature, as the operating characteristic value. Specifically, the detection unit 173 detects the amount of power consumption until the temperature of the controlled object at the time when the main body unit 171 starts operating reaches the set temperature. Then, the detection unit 173 detects the power efficiency by dividing the power consumption amount by the difference between the set temperature and the temperature of the controlled object.

The characteristic value information storage unit 174 stores the power efficiency detected by the detection unit 173 together with the detection time. The detection time is the time when the power consumption amount for calculating the power efficiency is detected by the main body unit 171.

The determination unit 175 determines the failure risk based on the power efficiency and the detection time detected by the detection unit 173. Specifically, the determination unit 175 extracts the power efficiency in which the detection time stored in the characteristic value information storage unit 174 is within a predetermined period (for example, one month) from the present. Then, for example, the determination unit 175 determines that the higher the ratio of the power efficiency in which the difference from the design value is equal to or greater than the reference value among the plurality of power efficiencies detected by the detection unit 173, the higher the failure risk. In this case, the failure risk is represented by a numerical value of 0 to 100%.

For example, the determination unit 175 determines that the failure risk is the first value when the ratio of the power efficiency whose difference from the design value is equal to or greater than the reference value is the first ratio or more among the plurality of power efficiencies. The determination unit 175 fails when the ratio of the power efficiency whose difference from the design value is equal to or greater than the reference value among the plurality of power efficiencies is less than the first ratio and greater than or equal to the second ratio smaller than the first ratio. It is determined that the risk is the second value lower than the first value. Further, the determination unit 175 determines that when the ratio of the power efficiency whose difference from the design value is equal to or greater than the reference value among the plurality of power efficiencies is less than the second ratio, the failure risk is lower than the second value. Is determined to be. Here, the first ratio, the second ratio, the first value, the second value, and the third value are the first ratio and the second ratio in the determination when the above-mentioned equipment 17 is a gas water heater and a gas stove, respectively. The first value, the second value, and the third value do not have to be the same.
