freezing equipment 34, power saving advice information for efficiently controlling the opening/closing of an electromagnetic valve and an output of a compressor in consideration of the set temperature of theair conditioning equipment 33 and the inside-store temperature. - The monitoring
PC 20 only monitors, with respect to thesolar battery 31 and the garbage disposer 36, the driving, and receives from the controller 10 a warning in a case where the equipment develops a fault. - [4] Description of Method of Producing Power Saving Advice Information for
Illuminating Equipment 32 - Referring to FIG. 3, a method of producing power saving advice information related to the
illuminating equipment 32 will be specifically described. Here, description is made of a method of producing power saving advice information related to theilluminating equipment 32 in onepredetermined store 1. - In the
predetermined store 1, the user sets desired illumination (desired inside-store illumination) for the controller (in-store controller) 10 (step 1). Thecontroller 10 acquires an outside-store illumination measured value from the outside-store illumination measuring device 44 (step 2). Thecontroller 10 transmits the illumination set by the user and the acquired outside-store illumination measured value to themonitoring PC 20 in the monitoring center 2 (step 3). Such processing is performed for each predetermined time period. - When the
monitoring PC 20 in themonitoring center 2 receives the set illumination and the outside-store illumination measured value from the controller 10 (step 11), it stores them in a storage device (step 12). - Processing for calculating an inside-store illumination adjustment level corresponding to all tomorrow is performed on the basis of the set illumination and the outside-store illumination measured value which have been so far received and data representing weather forecasting (step13).
- Description is made of the processing for calculating the inside-store illumination adjustment level. The
monitoring PC 20 produces a database for illumination estimation storing the date, the time, the probability of precipitation, and outside-store illumination, as shown in FIG. 4, on the basis of the data representing weather forecasting and the outside-store illumination measured value sent from thecontroller 10 in thepredetermined store 1. - The probability of precipitation for tomorrow is acquired from weather forecasting for tomorrow, and outside-store illumination, corresponding to several days in the past on which the probability of precipitation is the same as the probability of precipitation for tomorrow, are extracted, starting with the newest one from the database for illumination estimation. The averages of the extracted outside-store illumination, at the same time, corresponding to several days are respectively calculated. Consequently, an outside-store illumination estimated value for each time of all tomorrow is calculated, as indicated by A in FIG. 5.
- An outside-store illumination adjustment level (a recommended illumination level) for each time of all tomorrow is then determined, as indicated by B in FIG. 5, on the basis of the outside-store illumination estimated value for each time of all tomorrow and the received set illumination. That is, four types of inside-store illumination adjustment levels (
levels 1 to 4) are prepared using the set illumination as the best inside-store illumination adjustment level (level 4). The inside-store illumination adjustment level is determined such that the higher the outside-store illumination estimated value becomes, the lower the inside-store illumination adjustment level becomes. - Furthermore, an electricity rate corresponding to the difference in power consumption between a case where the illuminating
equipment 32 is driven for a whole day such that the set illumination is obtained and a case where the illuminatingequipment 32 is driven for a whole day such that the determined inside-store illumination adjustment level for each time is obtained is calculated. - The
monitoring PC 20 transmits data such as the recommended illumination level corresponding to all tomorrow thus obtained to thecontroller 10 in the predetermined store 1 (step 14). - When the
controller 10 receives the data such as the recommended illumination level from the monitoring PC 20 (step 4), it processes the data, and displays the processed data on a screen on the day of control (step 5). An example of the screen is illustrated in FIG. 6. The user operates thecontroller 10 with reference to displayed contents, to control the illuminatingequipment 32. - [5] Description of Method of Producing Power Saving Advice Information Related to
Air Conditioning Equipment 33 - Referring to FIG. 7, a method of producing power saving advice information related to the
air conditioning equipment 33 will be specifically described. Here, description is made of a method of producing the power saving advice information related to theair conditioning equipment 33 in onepredetermined store 1. - In the
predetermined store 1, the user sets a desired temperature (a desired inside-store temperature) for the controller (in-store controller) 10 (step 101). Thecontroller 10 acquires an inside-store temperature measured value, an outside-store temperature measured value, and an interior temperature measured value (a measured value of the interior temperature of the freezing showcase) from the inside-storetemperature measuring device 45, the outside-storetemperature measuring device 46, and the interiortemperature measuring device 47, and acquires the number of times of opening/closing from the counter 49 (step 102). Thecontroller 10 transmits the temperature set by the user, and the inside-store temperature measured value, the outside-store temperature measured value, the interior temperature measured value, and the number of times of door opening/closing which have been acquired to themonitoring PC 20 in the monitoring center 2 (step 103). Such processing is performed for each predetermined time period. - When the
monitoring PC 20 in themonitoring center 2 stores the inside-store temperature measured value, the outside-store temperature measured value, the interior temperature measured value, and the number of times of door opening/closing from the controller 10 (step 11), it stores them in a storage device (step 112). - Processing for calculating the inside-store temperature adjustment level corresponding to all tomorrow on the basis of the inside-store temperature measured value, the outside-store temperature measured value, the interior temperature measured value, and the number of times of door opening/closing which have been so far received, and data representing weather forecasting (step113).
- Description is made of the processing for calculating the inside-store temperature adjustment level. The
monitoring PC 20 produces a database for temperature estimation storing the date, the time, the inside-store temperature measured value, the outside-store temperature measured value, the interior temperature measured value, the number of times of door opening/closing per unit time, and weather, as shown in FIG. 8, on the basis of the data representing weather forecasting and the inside-store temperature measured value sent from thecontroller 10 in thepredetermined store 1. An interval Δt between times t is 10 minutes, for example. - An inside-store temperature estimated value (t+1) at time t+1 is defined by the following equation (1) using an inside-store temperature (t), an outside-store temperature (t), an interior temperature (t), and the number of times of door opening/closing (t) per unit time at time t, i.e., Δt before the
time t+ 1. - In the foregoing equation (1), a, b, c, and d are coefficients. Each of the coefficients a, b, c, and d is calculated by multiple regression analysis on the basis of data for one year in the past.
- Weather for tomorrow is then acquired from weather forecasting for tomorrow, and data, corresponding to several days in the past on which weather is the same as the weather for tomorrow, are extracted, starting with the newest one, from the database for temperature estimation. The averages of the extracted data, at the same time, corresponding to several days are respectively calculated for the inside-store temperature measured value, the outside-store temperature measured value, the interior temperature measured value, and the number of times of door opening/closing per unit time. Consequently, data representing the inside-store temperature measured value (the average), the outside-store temperature measured value (the average), the interior temperature measured value (the average), and the number of times of door opening/closing per unit time (the average) are obtained for each time of one day, as shown in FIG. 9.
- The obtained data for each time of one day {the inside-store temperature measured value (the average), the outside-store temperature measured value (the average), the interior temperature measured value (the average), and the number of times of door opening/closing per unit time (the average) are substituted in the foregoing equation (1), to calculate an inside-store temperature estimated value at the next time. Consequently, an inside-store temperature estimated value for each time of all tomorrow is obtained, as indicated by A in FIG. 10.
- An inside-store temperature adjustment level (a recommended temperature level) for each time of all tomorrow is then determined, as indicated by B in FIG. 10, on the basis of the inside-store temperature estimated value for each time of all tomorrow and the received set temperature. That is, four types of inside-store temperature adjustment levels (
levels 1 to 4) are prepared using the set illumination as the best inside-store temperature adjustment level (level 4). The inside-store temperature adjustment level is determined such that the higher the inside-store temperature estimated value becomes, the lower the inside-store temperature adjustment level becomes. - Furthermore, an electricity rate corresponding to the difference in power consumption between a case where the
air conditioning equipment 33 is driven for a whole day such that the set temperature is obtained and a case where theair conditioning equipment 33 is driven for a while day such that the determined inside-store temperature adjustment level for each time is obtained is calculated. - The
monitoring PC 20 transmits data such as the recommended temperature level corresponding to all tomorrow thus obtained to thecontroller 10 in the predetermined store 1 (step 114). - When the
controller 10 receives the data such as the recommended temperature level from the monitoring PC 20 (step 104), it processes the data, and displays the processed data on a screen on the day of control (step 105). An example of the screen is illustrated in FIG. 11. The user operates thecontroller 10 with reference to displayed contents, to control theair conditioning equipment 33. - Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.
