When there are a plurality of electrical facilities, there are as many electrical facilities IDs 33 and usage states 34 as there are electrical facilities.
The usage status registration process 21 analyzes the registered usage status data, and registers the usage status pattern data of the electrical equipment in the format shown in FIG. The day of week ID 51 indicates 8 patterns of holidays such as Sunday to Saturday and other holidays by 0 to 7. The time zone 52 is a time zone in which usage status data is registered, and indicates a time zone when 24 hours are divided in units of one hour. The electrical equipment usage rate 54 is a value indicating the ratio of the electrical equipment in use in the time zone indicated by the time zone 52. For example, when the data in the time zone 52 is “14”, it indicates that the time zone is from 14:00 to 15:00. The number of electrified equipment ID 53, the number of electrified equipment usage measurements 54, and the number of electrified equipment usage results 55 are registered in the storage device 25 as the number of electrified equipment connected to the information processing device 2 as usage status pattern data of the electrified equipment.

FIG. 7 is a flowchart showing the processing procedure of the usage status registration process 21.
First, usage pattern data corresponding to the current time registered in the storage device 25 is read (step S1), and the next update time is awaited based on the current time and the update time interval (step S2). Do. After the waiting time has elapsed, the usage status of each of the electrical equipments 4 to 6 is collected, and usage status pattern data for the time zone corresponding to the current time is searched (step S3). For example, if the current time is “December 21, 2003 (Sunday) 14:01”, the day ID 51 is “0” (Sunday), and the time zone 52 is “14” (14:00 to 15:00). The usage pattern data is searched for each electrical equipment ID. Then, the usage status data of the electrical equipments 4 to 6 is registered in the storage device 25 in the format shown in FIG. 3 (step S4), and the number of electrical equipment usage measurements 54 shown in FIG. 6 based on the registered usage status data. And the number 55 of electrical equipment use results is updated, and usage condition pattern data is updated (step S5). Specifically, 1 is added to the number of measurements of usage of electrical equipment 54 for each used usage pattern data, and the data corresponding to the electrical equipment ID 53 corresponding to the electrical equipment in use at the current time is applied to the electrical equipment. 1 is added to the number 55 of electrified equipment use results corresponding to the equipment ID 53.

On the other hand, the usage status history registration process 22 registers the usage status history data of each of the electric appliances 4 to 6 in the format shown in FIG. When the electrical equipment in the specific space 7 is used or unused, the usage status history data is stored in the storage device 26 as date data 41, time 42, electrical equipment ID 43, and usage status 44 as one record data. sign up.
When the usage state of each of the electrical equipments 4 to 6 is changed, usage status history pattern data is registered in the format shown in FIG. The usage status history pattern data includes a day ID 61, a time zone 62, an electrical equipment ID 63, and an electrical equipment usage time 64.

FIG. 8 is a flowchart showing the processing procedure of the usage status history registration processing 22.
First, the usage status history pattern data registered in the storage device 26 is read (step S11), and the standby state (step S12) is entered until the usage state of the electrical equipment changes. When the electrical equipment is in use or unused, use status history data is registered in the storage device 26 in the format shown in FIG. 4 (step S13). Then, the usage status history pattern data is updated based on the registered usage status history data (step S14).
The usage status history pattern data includes the day of week ID 61, time zone 62, and electrical equipment ID 63 shown in FIG. 6 when the electrical equipment is in use, and the current time when the electrical equipment is unused. Based on the time zone 62, the usage time of the electrical equipment is registered in the electrical equipment usage time 64.
The electrical equipment monitoring process 23 monitors the usage state of the electrical equipments 4 to 6 in the specific space 7 based on the data registered in the usage situation registration process 21 and the usage situation history registration process 22.

FIG. 9 is a flowchart showing a processing procedure for monitoring the use / unused state of the electrical equipment in the electrical equipment monitoring process 23.
The electrical equipment monitoring process 23 waits until any electrical equipment is used in the monitoring mode (step S21), and the standby state is released when any of the electrical equipments 4 to 6 is in use. Is done.
In the monitoring mode, the usage status registration process 21 and the usage status history registration process 22 operate in the same manner as in the registration mode. The electrical equipment monitoring process 23 uses the usage status registered in the usage status registration process 21 in the monitoring mode. Data and usage status pattern data are read (step S22), and it is determined whether the current usage status of the electrical equipment matches the usage status patterns accumulated so far (step S23). If they match, the usage status history data and usage status history pattern data registered in the usage status history registration process 22 in the monitoring mode are read (step S24), and whether they match the current usage history pattern of the electrical equipment. Judgment is made (step S25). If the usage pattern does not match or if the usage history pattern does not match, there is a suspicion that a unique event has occurred in the usage status of the electrical equipment. When the user answers the phone, a password input request message for authentication confirmation flows (step S26), and the input password is analyzed (step 27). If the password entered from the telephone 3 is correct, it is determined that the original user is living normally, and the usage status of the electrical equipment is determined to be normal. If the entered security code is incorrect or you do not answer the phone, it is considered that the original user is not in a normal living condition or that a suspicious person has entered, and that an unusual event has occurred. Judgment is made, and the administrator is notified to the emergency contact mobile terminal 1 (step 28).

FIG. 10 is a flowchart showing details of the electrical equipment specific event determination process based on the usage status pattern in the electrical equipment monitoring process 23, and details the processing (step S23) for determining that a specific event is detected based on the usage status pattern data of FIG. It is a thing.
First, it is confirmed from the usage status data whether each electrical equipment is in use (step S31). If the usage status is in use, the usage of the electrical equipment in the usage status pattern data having the day ID 51 and the time zone 52 corresponding to the time concerned The actual number 55 is divided by the number of measured use of electrical equipment 54 to obtain the electrical equipment usage rate, and it is confirmed whether the electrical equipment usage rate is less than or equal to the usage standard value (step S32). If the electrical equipment usage rate is less than the usage standard value, it is possible that the electrical equipment is in use on the day of the week and time when the electrical equipment should not be used. It is confirmed whether or not the number of performed is equal to or greater than the reference number (step S34). When the number of specific event determinations is equal to or greater than the reference number, it is determined that a specific event is detected (step S35), and when it is less than the reference number, the number of specific event determinations is incremented by one (step S36). Similarly, if the electrical equipment is unused, it is confirmed whether the electrical equipment usage rate 54 in the usage pattern data is equal to or greater than the unused reference value (step S33). If the electrical equipment usage rate 54 is equal to or higher than the unused reference value, the electrical equipment may be unused on the day of the week and the time of day when the electrical equipment should be used. It is confirmed whether or not the number of times determined to be detected is equal to or greater than the reference number (step S34). When it is not determined that the specific event is detected, it is determined whether or not the confirmation process has been completed for all the electrical equipment IDs (step S37).
That is, collect the usage status of each electrical equipment in the normal life state, register the usage status as usage status pattern data, and compare it with the usage status pattern collected in the monitoring mode in the monitoring mode, If the usage rate and unused rate of any of the electrical facilities exceed the allowable range, and the number of times exceeding that exceeds the reference number, it is determined that a specific event has occurred.
Similarly, in the process of step S24 of FIG. 9, it is determined whether or not a specific event has occurred based on the usage history pattern data.
That is, the usage status of each electrical equipment is collected in the normal living state, the usage status is registered as usage status history pattern data, and compared with the usage status history pattern collected in the monitoring mode in the monitoring mode. However, when the usage time and unused time of any of the electrical facilities exceed the allowable range, and the number of times exceeding the reference number exceeds the reference number, it is determined that a specific event has occurred.
