Description

  The present invention operates an electrical device in a house according to a time schedule, thereby giving an impression to a person outside the house even when there is no person in the house. The present invention relates to a security device for deterrence.

  Conventionally, by operating electrical equipment (home appliances) installed in the house according to the time schedule while the housekeeper is away, it is possible to give an impression to the person outside the house as if the housekeeper is in the house. A security device has been proposed.

  In this type of security device, it is possible to control the electrical devices in the home through a network (home network) formed in the home, and the drive history of each electrical device (changes in drive content, time when the drive content changes, etc.) through the network It is considered to create a time schedule for driving each electric device when a householder is at home (see, for example, Patent Document 1).

In the technique described in Patent Document 1, since a time schedule for driving an electric device is automatically created when the housekeeper is away from home, there is no need to set the time schedule. Since the time schedule is created based on the history of driving the equipment, the timing of driving the electrical equipment is the same as when the householder is at home, and whether the householder is away from home even when away from home It becomes possible to give such an impression.
JP 2005-277965 A

  However, in the technique described in Patent Document 1, it is necessary to lay a network that enables control of electrical equipment in a house, and it is difficult to use in an existing house. In addition, since the time schedule is created based on the driving history of the electrical equipment when the housekeeper is at home, there is an advantage that setting the time schedule does not take time and effort. In some cases, electric devices that are not useful for giving such an impression may operate according to a time schedule. For this reason, unnecessary electric power may be consumed by driving unnecessary electrical devices.

  The present invention has been made in view of the above-mentioned reasons, and its purpose is to easily introduce even an existing house when driving an electric device so as to give an impression that the person is at home when the resident is away from home. It is another object of the present invention to provide a crime prevention device that can prevent the generation of wasteful power consumption due to unnecessary driving of an electric device as well as being troublesome in selecting an electric device to be driven.

  The invention according to claim 1 is a crime prevention device that gives an impression to a person outside the home that an electric device provided in a house is automatically operated according to a time schedule, and gives an impression as if the user is away from home. A wireless transmission unit for transmitting a wireless signal for driving the wireless device, a wireless reception unit for receiving a wireless signal by operating a remote control device when the user drives an electric device, a clock unit for measuring the time of the day, and wireless A drive history acquisition unit that acquires, as a drive history, an electric device driven by a user based on a wireless signal received by the reception unit and a time counted by the clock unit, a driving content, and a time, and a drive history acquisition A history storage unit that stores the drive history acquired by the unit, and a set of the electric device, the drive content, and the time based on the drive history stored in the history storage unit A schedule generation unit that sets a time schedule that is a combination, a schedule storage unit that stores a time schedule generated by the schedule generation unit, a time schedule stored in the schedule storage unit, and a time counted by a clock unit A schedule execution unit for transmitting a wireless signal from the wireless transmission unit to the electrical device so as to automatically drive the electrical device based on the selection, and a selection target storage unit that defines the electrical device to be stored in the history storage unit and the content of the drive When the wireless signal is received by the wireless reception unit, the drive history acquisition unit collates with the selection target storage unit, and the electrical device included in the wireless signal and the drive content are registered in the selection target storage unit. Acquires electric equipment, drive details and time as drive history To.

  According to a second aspect of the present invention, in the first aspect of the invention, the selection target storage unit includes a daily pattern relating to the electric device and the driving content in addition to the electric device and the driving content stored in the history storage unit. If the drive history used when setting the time schedule has pattern characteristics, the schedule generation unit may determine the drive history of another day within the specified allowable time with respect to the time of the drive history. The time is obtained and the average value of the times is set as the time of the time schedule.

  According to a third aspect of the present invention, in the first aspect of the invention, the selection target storage unit includes a daily pattern relating to the electric device and the driving content in addition to the electric device and the driving content stored in the history storage unit. If there is no pattern in the driving history used when setting the time schedule, the schedule generation unit will determine the driving history of the other day within the specified exclusion time with respect to the time of the driving history. The presence / absence is determined, and if there is no driving history for another day, the driving history is used for the time schedule, and if there is a driving history for another day, the driving history is not used for the time schedule.

  According to the configuration of the first aspect of the present invention, the wireless signal transmitted from the remote control device is received when the user operates the remote control device to drive the electric device, and the user actually drives from the wireless signal. The time schedule for driving the electrical device when it is away is set by extracting the selected electrical device and the content and time of the drive, so the electrical device is driven in the same way as when the user actually drives the electrical device at home The user does not have the hassle of selecting an electric device to be driven from various electric devices in the house and setting the content and time of driving in order to create a time schedule for absence. There are advantages.

  Also, the wireless signal transmitted from the remote control device to the electrical device is received and the driving history is extracted, and the electrical device is instructed to drive according to the time schedule by transmitting the wireless signal. There is no need to lay a net and it can be easily installed in existing houses.

  Furthermore, when the electrical device included in the wireless signal and the content of the drive are registered in the selection target storage unit, the drive history is stored based on the wireless signal, and therefore, all the drive histories are employed in the time schedule. Instead, only the necessary driving history is used as the time schedule, and there is no waste of driving unnecessary electrical equipment to leave home, and wasteful power consumption can be prevented from occurring.

  According to the configuration of the invention of claim 2, it becomes possible to select a driving history to be adopted as a time schedule at the time of absence based on the pattern property (daily repetitive pattern) between the electric device and the driving content. It becomes possible to drive the electric device in a pattern for driving the electric device every day when the user is at home. In other words, since the user drives the electric device according to the pattern characteristics when the electric device is driven, the driving of the electric device has a natural impression that is the same as when the house is at home, and enhances the crime prevention effect. Can do.

  According to the configuration of the invention of claim 3, even if there is no pattern in driving electric equipment, driving history is adopted in the time schedule on the assumption that hunting does not occur if there is no driving history of the same type within the specified exclusion time. Therefore, it is possible to change the drive of the electric device when the user is away, and to make it difficult for a person outside the home to notice that the user is away.

(Embodiment 1)
As shown in FIG. 1, a crime prevention device 1 according to the present embodiment includes an electric device 2 provided in a house and instructed to be driven by reception of a wireless signal, and a remote control device 3 that transmits a wireless signal to the electric device 2. Used. Many of the wireless signals used in the electrical equipment 2 use infrared rays as a transmission medium, but wireless signals using radio waves as a transmission medium may be used. However, a case where infrared rays are used as a transmission medium will be described below as an example. The security device 1 can transmit and receive a wireless signal, and can transmit a wireless signal instructing driving of the electric device 2.

  The crime prevention device 1 includes a wireless transmission unit 11 that transmits a wireless signal to the electrical device 2 and a wireless reception unit 12 that receives a wireless signal from the remote control device 3. The wireless transmission unit 11 includes a light emitting diode that emits infrared rays as a light emitting element, and transmits a wireless signal instructing the content of driving (for example, start or stop) to the electric device 2 by being controlled by the schedule execution unit 10. . The instruction to the electric device 2 is not only the start and stop of driving, but also the channel and volume can be changed if the electric device 2 is a television receiver. That is, basically, the crime prevention device 1 can instruct that the remote control device 3 can instruct the electric device 2.

  However, lighting equipment, audiovisual equipment, air conditioners, fans, etc. are generally used as the electrical equipment 2 that is instructed to be driven by a wireless signal, but the impression is as if a home away from home. It is necessary for the electric device 2 that is driven to provide the power to recognize the driving of the electric device 2 visually or audibly outside the home. In addition, since it is driven when a house resident is not present in the house, it is not desirable to drive the electric device 2 with high power consumption. Therefore, the electric equipment 2 excludes a video deck, a DVD player, an air conditioner, a fan, and the like. In addition, the contents of the drive that the instruction given to the electric device 2 does not affect the visual and auditory perceptions of people outside the home are excluded from the instruction of the electric device 2 in the security device 1. Whether or not to instruct the electric device 2 and the content of driving by a wireless signal is determined by the registered content of the selection target storage unit 16 to be described later.

  The security device 1 is provided with an electrical device 2, a schedule storage unit 13 in which a time schedule that is a combination of the driving content and time of the electrical device 2 is registered, and a clock unit 14 that counts the current time. When the current time measured by the clock unit 14 coincides with the time schedule stored in the schedule storage unit 13, the schedule execution unit 10 drives the electric device 2 according to the driving content set in the time schedule. Then, a wireless signal is transmitted from the wireless transmission unit 11. In addition, if the wireless signal is transmitted only once, the electrical device 2 may fail to receive the wireless signal, and the electrical device 2 may not perform the operation according to the time schedule. You may make it transmit.

  In transmitting the wireless signal according to the time schedule, the schedule execution unit 10 actually reads the time from the clock unit 14 at regular time intervals, and the time read in the previous time and the current time read out among the times set in the time schedule. The wireless transmission unit 11 determines whether or not there is a time set between the wireless transmission unit 11 and the wireless storage unit 11 according to the time schedule to which the time is assigned. A wireless signal is transmitted. Of course, if the time between the read time and the previous time does not exist in the schedule storage unit 13, the wireless signal is not transmitted.

  The time schedule to be stored in the schedule storage unit 13 is created based on the wireless signal received by the wireless reception unit 12. Below, the operation | movement which produces a time schedule based on the wireless signal received with the wireless receiving part 12 is demonstrated.

  The wireless receiving unit 12 includes a phototransistor or a photodiode that receives infrared rays as a light receiving element, and receives a wireless signal transmitted from the remote control device 3 to the electric device 2 when the user drives the electric device 2. That is, a wireless signal transmitted from the remote control device 3 to the electrical device 2 is intercepted. Since the wireless signal includes the electric device 2 and the content of driving (starting, stopping, and changing of driving), the security device 1 can intercept the wireless signal from the remote control device 3 to the electric device 2. It is possible to know which electrical device 2 is instructed how to drive.

  When the wireless reception unit 12 receives a wireless signal from the remote control device 3 to the electrical device 2, the drive history acquisition unit 15 provided in the crime prevention device 1 selects the electrical device 2 and the drive content acquired from the wireless signal as the selection target storage unit 16. To match. The selection target storage unit 16 registers the electric device 2 that is driven when the user is away and the content of the drive. In the drive history acquisition unit 15, the electric device 2 and the drive content acquired from the wireless signal are collated with the content registered in the selection target storage unit 16, and if there is a match with the registration content in the selection target storage unit 16. Then, the electric device 2 acquired from the wireless signal and the content of the drive are associated with the current time measured by the clock unit 14.

  That is, the drive history acquisition unit 15 acquires, as a drive history, the combination of the electric device 2 driven by the wireless signal from the remote control device 3 and the content and time of the drive, and the drive history is provided in the security device 1. The data is stored in the storage unit 17. Therefore, in the history storage unit 17, the driving history is stored for the electric device 2 registered in the selection target storage unit 16 and the driving content among the electric devices 2 that can be intercepted by the crime prevention device 1.

  By the way, a plurality of electric devices 2 are usually provided in a house, and the security device 1 can individually instruct the plurality of electric devices 2 to be driven by a wireless signal. In the case of using the wireless device, the reach range of the wireless signal is limited to one room or the like. Therefore, when driving the electric equipment 2 provided in a plurality of rooms, a plurality of crime prevention devices 1 may be provided in the home, 1, only the wireless transmission unit 11 and the wireless reception unit 12 may be separated and provided at a plurality of locations. Also, in order to prevent the formation of blind spots in the transmission and reception of wireless signals even in one room, as shown in FIG. 2, near the center of the room (near the center when projected onto the floor) and at a high place (for example, the ceiling) It is desirable to arrange the security device 1 (in particular, the wireless transmission unit 11 and the wireless reception unit 12). Further, a plurality of light emitting elements of the wireless transmission unit 11 and a plurality of light receiving elements of the wireless reception unit 12 are arranged so that the blind spots are not easily formed in the wireless transmission unit 11 and the wireless reception unit 12 as well. It is desirable to design the system.

  The drive history stored in the history storage unit 17 is not used for the time schedule as it is, but is given to the schedule generation unit 18 to generate a time schedule based on the drive history. The time schedule generated by the schedule generation unit 18 is stored in the schedule storage unit 13. That is, as described above, the time of the time schedule stored in the schedule storage unit 13 is compared with the time measured by the clock unit 14, and when both times match, wireless transmission is performed to the electrical device 2 according to the time schedule. A wireless signal is transmitted from the unit 11. With this operation, the electric device 2 is automatically driven according to the time schedule set in the security device 1.

  Note that the porch light and gate light usually do not instruct to drive using a wireless signal, but it is necessary to turn on and off the porch light and gate light to leave home away from home when away from home. It is desirable to replace the switch for instructing the turning on / off of the pouch light and the gate light with a switch that enables an instruction by a wireless signal.

  Here, in the crime prevention apparatus 1, the home mode and the absence mode can be selected by a mode switching switch (not shown). In the at-home mode, the driving history is stored in the history storage unit 17, and in the absence mode, the electric equipment according to the time schedule. 2 is automatically driven.

  As described above, the time schedule is created from the driving history acquired by intercepting the wireless signal transmitted from the remote control device 3 to the electric device 2, and the instruction to the electric device 2 according to the time schedule is performed by the wireless signal. There is no need to lay a home communication network in the house as in the conventional configuration, and it can be easily introduced into an existing house.

  Moreover, since the driving history acquired from the actual driving result of the electric device 2 when the user is at home is stored and the time schedule is generated from the driving history, the electric device 2 is used for the user to create the time schedule. There is no need to register it in consideration of the contents of driving and the time, and time schedule setting is not time-consuming. In addition, not all the driving results of the electric device 2 by the user are used, but only the driving results matching the electric device 2 and the driving contents registered in the selection target storage unit 16 are set as the driving history, and this driving is performed. Since the time schedule is generated based on the history, it is possible to prevent useless power consumption without causing the electric device 2 to operate wastefully.

  In the security device 1, the configuration excluding the wireless transmission unit 11 and the wireless reception unit 12 is configured by a computer, and the schedule storage unit 13, the selection target storage unit 16, and the history storage unit 17 include semiconductor memories (RAM, EEPROM, etc.). ) Is used. In addition, the contents of the selection target storage unit 16 may be set in advance by the manufacturer of the security device 1, but in order to enable a change by the user himself, a display unit such as a liquid crystal display, You may provide the crime prevention apparatus 1 with the operation part like the switch or touch switch which can be operated according to the content displayed on the screen of a display part. In this case, if the electric device 2 used in the selection target storage unit 16 and the content of driving can be selected from a plurality of options, it is convenient for the user without any trouble.

  In this embodiment, a procedure for acquiring a control history using a wireless signal transmitted from the remote control device 3 to the electric device 2 and creating a time schedule from the control history is shown in FIG. First, when a user operates the remote control device 3 to transmit a wireless signal to the electrical device 2, the security device 1 intercepts the wireless signal at the wireless receiving unit 12 (S1). The wireless receiving unit 12 extracts a bit string from the received wireless signal as a received signal (S2). Since this bit string includes the electric device 2 and the content of the drive, the drive history acquisition unit 15 collates with the content of the selection target storage unit 16 (S3). Here, it is assumed that the selection target storage unit 16 stores a bit string having the same format as the bit string of the reception signal extracted from the wireless signal received by the wireless reception unit 12.

  When matching information is included in the selection target storage unit 16 (S4: yes), the current time (time within a day) is read from the clock unit 14 (S5), and the electric device 2 and the drive obtained from the wireless signal are driven. Is stored in the history storage unit 17 together with the time read from the clock unit 14 (S6). When the drive history is stored in the history storage unit 17, a time schedule is generated in the schedule generation unit 18 (S 7), and the generated time schedule is stored in the schedule storage unit 13. If there is no matching information in the selection target storage unit 16 regarding the electrical device 2 and the drive content included in the wireless signal (S4: no), the wireless signal is not involved in the generation of the time schedule.

(Embodiment 2)
In the first embodiment, attention is paid only to the driving history within one day stored in the history storage unit 17, but in the present embodiment, the driving contents of each electric device 2 have daily repeatability or periodicity. Whether or not the same electrical equipment 2 is driven with the same content almost at the same time every day is said to have pattern characteristics. The presence / absence of the pattern property is registered in the selection target storage unit 16 as shown in Table 1. That is, in the selection target storage unit 16, presence / absence of pattern property is set together with the type of the electric device 2 and the content of driving.

The pattern property “present” means that the drive is performed with the same content at approximately the same time every day, and the approximately same time indicates that the range of variation in the drive time is within an allowable time (for example, before and after 30). Within minutes). For example, the lighting equipment is turned on and off at almost the same time every day, so the pattern is “Yes”. Also, “None” of the pattern property corresponds to a channel change of a television receiver or the like. The presence / absence of the pattern property is set in the same manner as long as it is the same type of electric device 2 regardless of the manufacturer of the electric device 2. The allowable time may be fixed or set by the user.

  Below, the procedure in which the schedule production | generation part 18 produces | generates a time schedule from the drive history memorize | stored in the log | history memory | storage part 17 is demonstrated using FIG. It is assumed that driving history for a plurality of days is stored in the history storage unit 17.

  The schedule generation unit 18 collates the presence / absence of pattern property with respect to each driving history stored in the history storage unit 17 with the selection target storage unit 16 (S11). When the pattern property is “Yes” (S12: yes), the schedule generation unit 18 drives the drive history of the same electrical device 2 and the same drive content of another day within the allowable time with respect to the time of the focused drive history (hereinafter, “same type”). (Referred to as “driving history”) from the history storage unit 17, and the average value of the time relating to the read driving history is obtained (S13). The schedule generation unit 18 registers the time schedule related to the electric device 2 and the content of driving in the schedule storage unit 13 using the average value of the obtained times as the time (S14).

  On the other hand, when the pattern property is “none” (S12: no), the schedule generation unit 18 sets the exclusion time (the time of the focused driving history) set to a time different from the allowable time described above with respect to the time of the focused driving history. Search for the same type of driving history of other days in the history storage unit 17 (S15). The exclusion time may be changed by the user even if it is fixedly set like the allowable time. In many cases, the exclusion time is set shorter than the allowable time.

  If there is no drive history of the same type within the exclusion time in the history storage unit 17 (S16: no), the schedule generation unit 18 registers the focused drive history in the schedule storage unit 13 as a time schedule (S17). That is, since there is no drive history of the same type within the exclusion time defined before and after the focused drive history, even if this drive history is adopted as a time schedule, on / off of the same electrical device 2 is repeated in a short time. No (that is, no hunting occurs).

  On the other hand, if there is the same type of drive history within the exclusion time with respect to the time of the target drive history in the history storage unit 17 (S16: yes), if the target drive history is used as the time schedule, the same electrical device 2 is turned on / off. Since off may be repeated in a short time, in this case, the driving history of interest is not adopted as the time schedule.

  As described above, by changing the procedure for setting the time schedule in accordance with the presence or absence of pattern characteristics, hunting does not occur in the operation of the electric device 2, but not only the drive with pattern characteristics but also the pattern characteristics. As a result, it becomes more difficult for the person outside the home to know whether the home is at home or away. Other configurations and operations are the same as those of the first embodiment.

It is a block diagram which shows embodiment of this invention. It is the schematic which shows the installation state same as the above. FIG. 3 is an operation explanatory diagram of the first embodiment. FIG. 9 is an operation explanatory diagram of the second embodiment.
