(Embodiment)
The display method, program, and display system according to the present embodiment will be described.

(1) Overall Overview In the present embodiment, a display system having, as a basic function, a function for displaying power information related to power consumption during a predetermined period in a facility and control information related to control affecting power consumption. Will be described. The control information includes timing information related to the timing at which control is performed.

  In the present embodiment, the display system 10 included in the computer system is configured by a server 1 that creates content to be displayed on the information terminal 3, as shown in FIGS. The “facility” here means a non-residential facility such as an office building, a commercial facility, a hospital, a welfare facility, a hotel or a factory that receives power supply. The “facility” includes not only a facility that receives power supply from an electric power company such as an electric power company, but also a facility that receives power supply from a power generation facility such as a solar power generation facility. The facility is not limited to a non-residential building such as a building, but may be an apartment house or a detached house.

  As shown in FIG. 2, the server 1 is connected to the controller 21 provided in the facility 5 via the network 4. As shown in FIG. 2, the server 1 is connected to an information terminal 3 including a display unit 31 via a network 4.

  The facility 5 is provided with a plurality of devices 50. The plurality of devices 50 are, for example, lighting fixtures 50a to 50c, air conditioning devices 50d to 50e, and the like. The plurality of devices 50 can communicate one-to-one with a plurality of input / output devices (I / O devices) 25 that can communicate with the controller 21.

  The communication method between each of the controller 21 and the I / O device 25 and the communication method between the I / O device 25 and the device 50 are, for example, wired communication such as RS232C and RS485. Note that the communication method between each of the controller 21 and the I / O device 25 and the communication method between the I / O device 25 and the device 50 are Wi-Fi (registered trademark) or small that does not require a license. Wireless communication such as power wireless (specific low-power wireless) may be used. For this type of low-power radio, specifications such as the frequency band to be used and the antenna power are defined in each country depending on the application. In Japan, low-power radio that uses radio waves in the 920 MHz band or 420 MHz band is defined.

  The controller 21 has a demand control function for suppressing an increase in the maximum demand power of the facility 5 as a main function. The “maximum demand power” here is also called a power receiving point demand power or a demand value, and each of the average power consumption (average value of power consumption) in a predetermined (for example, every 30 minutes) demand time period. This is the maximum value in a month (one month). The maximum value of the maximum demand power in the past year is called “contract power”. Based on this contract power, the customer (the manager of the facility 5 or the user) There is a system that determines the electricity bills paid to businesses. Under such a system, the controller 21 suppressing the maximum demand power of the facility 5 leads to the suppression of the electricity bill. In short, with the demand control function, the controller 21 can suppress an increase in average power consumption during the demand time limit at the facility 5, and can suppress an increase in electricity charges by suppressing the "maximum demand power" below the current contract power. is there. The suppression of the increase in average power consumption is basically realized by controlling at least one device 50 (see FIG. 2) among the plurality of devices 50 in the facility 5.

  Here, the maximum demand power is the maximum value of the average power consumption for one month in the demand time period, but the average power consumption in the demand time period is a constant (predetermined) in the power consumption amount (time integrated value of power consumption) in the demand time period. It is expressed by multiplying by the coefficient. For example, when the demand time period is 30 minutes, x [kWh] that is the power consumption amount of the demand time period is doubled to obtain 2x [kWh] that is the power consumption amount for one hour. The average power consumption in the demand time period at this time is a value obtained by multiplying the power consumption amount in the demand time period by a constant (in this case, “2”), that is, 2 × [kW]. Therefore, in demand control, suppressing the power consumption amount in the demand time period to a certain target value (demand target value) or less means that the average power consumption in the demand time period is less than a certain power target value (twice the demand target value). It is equivalent to restraining. Therefore, the controller 21 controls the device 50 of the facility 5 as demand control so that the power consumption amount in the demand time period does not exceed the demand target value, thereby suppressing an increase in the average power consumption in the demand time period.

  The controller 21 calculates the average power consumption in the demand time limit of the facility 5 based on the value of the current measured by the current sensor 22 and transmits it to the server 1. When the controller 21 performs demand control, the controller 21 transmits control information related to demand control to the server 1.

  When each of the plurality of I / O devices 25 receives a control command for the connected device 50 from the controller 21, it controls the device 50 according to the received control command. For example, the I / O device 25 controls the power on / off of the device 50 in accordance with the control command. The I / O device 25 includes a contact output to which the device 50 is connected. The controller 21 instructs the I / O device 25 to turn on / off the contact output, thereby controlling the on / off of the device 50.

  In addition, when the control target is at least one of the lighting fixtures 50a to 50c, the I / O device 25 controls the dimming of the lighting fixture according to the control command (for example, control is performed so that the illumination is darkened). To do). Further, when the control target is at least one air conditioner among the air conditioners 50d to 50e, the I / O device 25 controls at least one of the set temperature of the air conditioner and the air volume according to the control command.

  The information terminal 3 displays the information (content) output by the display system 10 (server 1) on the display unit 31. Thereby, the information terminal 3 can present the information (content) created by the display system 10 to the owner of the information terminal 3. Here, the owner is, for example, the owner who requested the construction of the facility 5 or the person in charge of the construction shop who has undertaken the construction.
