Description

  The present invention relates to a home appliance control device and a home appliance control system, and is particularly useful when applied to a case where home presence or absence is detected and control is performed so that home appliances are in a state suitable for each.

  In recent years, home appliance control by so-called home automation has become widespread in ordinary households. According to this, the user can set each household appliance arbitrarily, for example by operating a dedicated terminal, a personal computer, a mobile phone, etc. (for example, refer to patent documents 1). In addition, there are also technologies that provide sensors to detect people and temperature, etc., indoors and outdoors, and automatically change the state of household electrical appliances based on detection signals from these sensors and notify the presence / absence of people. Yes (see, for example, Patent Document 2).

  However, in home automation, home appliances can be controlled centrally from a dedicated terminal, etc., but the operation of the dedicated terminal etc. is performed by a person, and the home appliances autonomously change their status depending on the situation. It does not change. That is, there is a problem that the work burden still remains manually.

  Moreover, when controlling household appliances based on the detection signal by a sensor, it is difficult to adjust how the household appliances are controlled when the input information from the sensor is at what value. For example, when controlling to turn on the light when at home or to turn off the light when not at home, it is necessary to determine whether it is home or away from the detection signal of the sensor, but adjustment for this determination is troublesome. is there.

  Furthermore, since it must be adjusted and managed for each combination of the sensor and the home electric appliance, there is a problem that centralized management cannot be performed and the management burden increases. In addition, there is a problem that it takes time and cost for installing each sensor.

  As described above, the related art has a problem that costs associated with the installation of special devices such as sensors, and time and effort for adjusting the sensors and the like so that home appliances are appropriately controlled.

  ADVANTAGE OF THE INVENTION According to this invention, it is an inexpensive and simple structure, and the household appliance control apparatus and household appliance control system which do not require a troublesome setting are provided.

  Hereinafter, the best mode for carrying out the present invention will be described. The description of the present embodiment is an exemplification, and the present invention is not limited to the following description.

  FIG. 1 is a conceptual diagram showing one usage pattern of the home appliance control system according to the present embodiment, and FIG. 2 is a functional block diagram of the home appliance control system according to the present embodiment. As shown in FIG. 1, the home appliance control system includes a home appliance control device 20 that controls home appliances, and a home server 30 that exchanges data with the home appliance control device 20. These home appliance control device 20 and home server 30 are installed on the first floor of the house.

  Although the details will be described later, the home appliance control device 20 also has a function of a so-called wireless LAN router having a function of a wireless LAN base station and a relay function to the Internet, and has a specific frequency band (2.4 GHz). Communication data can be transmitted and received between the home server 30 and the personal computer 11 installed on the second floor by radio waves.

  A telephone base unit 8 and a microwave oven 10 are installed on the first floor of the house, and a handset 9 that can communicate with the base unit 8 is installed on the second floor. The master unit 8 and the slave unit 9 are digital cordless telephones, and wireless communication is possible using radio waves of a predetermined frequency, but these radio waves are in a frequency band that interferes with a specific frequency band of the home appliance control device 20. It is a radio wave (interference radio wave). In the microwave oven 10, the radio wave used when heating food or the like is a radio wave in a frequency band (interference radio wave) that interferes with a specific frequency band of the home appliance control device 20.

  In addition, as an example of home appliances to be controlled by the home appliance control apparatus 20, 1F illumination, 1F illumination 2, 1F air conditioner 3, 2F air conditioner 4, 1F intrusion detector 5, and 2F intrusion detector 6 are illustrated in the drawing. It is installed on the first and second floors. These home appliances are connected to a home controller 7 installed on the first floor. The home controller 7 can transmit and receive communication data to and from the home appliance control device 20 via the wireless LAN in the same manner as the personal computer 11, and the home appliance control device 20 controls each home appliance via the home controller 7. Is possible. The 1F intrusion detector 5 detects a person entering from the first floor window, and the 2F intrusion detector 6 detects a person entering from the second floor window. It is possible to acquire the detection signals from these intrusion detectors 5 and 6 via. In addition, the home appliance control device 20 can also acquire the state of each home appliance (whether the lighting is on, the set temperature of the air conditioner, etc.).

  The home appliance control device 20 includes a wireless communication unit 21, an interference detection unit 22 that detects an interference radio wave that interferes with a specific frequency band used for the wireless LAN, and a home appliance control unit 23 that controls the home appliance. Each of these means is configured as an electronic circuit, but may be implemented as software. Although not shown in particular, it has a router function for relaying between the personal computer 11 and the Internet.

  The home server 30 is an information communication device including a general CPU, a storage device, and an input / output device, and includes a traffic pattern forming unit 31, a determination unit 32, and a setting unit 33. Each of these means is implemented as software, but may be configured as an electronic circuit.

  The wireless communication means 21 realizes a wireless LAN function for transmitting and receiving communication data with the personal computer 11 using radio waves in a specific frequency band. In this embodiment, since the wireless LAN is based on the IEEE802.11g standard, the specific frequency band is 2.485 to 2.490 (GHz), and the communication speed is 54 Mbps at the maximum.

  The interference detection unit 22 detects interference radio waves generated in the external device, that is, the parent device 8, the child device 9, and the microwave oven 10. The interference radio wave here refers to a radio wave that interferes with a specific frequency band used by the wireless communication means 21.

  The traffic pattern forming unit 31 forms a traffic pattern in which the amount of communication data transmitted and received by the wireless communication unit 21 is recorded for a certain period. Specifically, the communication data amount transmitted / received by the home appliance control device 20 by the wireless communication means 21 is measured, and the communication data amount is transmitted to the home server 30 via the wireless LAN. The home server 30 records the amount of communication data together with the received time. A traffic pattern is obtained by accumulating the received time and communication data amount for a certain period. When such a traffic pattern is formed, for example, the transition of the daily communication data amount is recorded.

  Using this traffic pattern and the fact that the amount of data that can be communicated by wireless LAN when interference radio waves are generated during communication by the wireless communication means 21 is used, whether or not there is a person in the house and the behavior pattern can be determined. Can be guessed. For example, if a person exists in a house and lives, a call may be performed between the parent device 8 and the child device 9. When an interference radio wave is generated by this call, the traffic pattern records that the communication data amount has decreased at a certain time. From this, if there is a portion in which the amount of communication data is reduced in the traffic pattern, it can be understood that a call is made between the parent device 8 and the child device 9 at that time, that is, at home.

  For example, in the traffic pattern, there is a portion where the amount of communication data decreases in the morning and evening hours, so it can be seen that a person talks on the master unit 8 or the slave unit 9 or operates the microwave oven 10. In the time zone, it is possible to infer the person's behavior pattern from the traffic pattern, such as showing that the part where the communication data amount has not decreased appears, so that the person is out.

  The traffic pattern is not limited to one, and a plurality of traffic patterns may be formed. For example, a home traffic pattern when a person is present in a house and an absent traffic pattern when a person is not present in the house may be formed. Thereby, as will be described later, it becomes possible to control home appliances suitable for each based on the traffic pattern at home and at home.

  The determination unit 32 determines whether the communication data amount in the wireless communication unit 21 is different from the traffic pattern formed in the past. More specifically, when the home appliance control device 20 detects the interference radio wave with the interference detection means 22, the communication data amount at that time is transmitted to the home server 30 via the wireless LAN. When the interference data is detected by the wireless communication unit 21 when the interference detection unit 22 detects the interference radio wave, the determination unit 32 is different from the communication data amount of the traffic pattern at the same time as the detection time of the interference radio wave. It is determined that transmission / reception of communication data by the wireless communication means 21 is in an abnormal state.

  For example, the determination unit 32 compares the communication data amount A (Mbps) at the wireless communication unit 21 at 17:00 on a certain day with the communication data amount B (Mbps) at 17:00 in the traffic pattern. When the communication data amounts A and B are different, it is determined that transmission / reception of communication data by the wireless communication means 21 is in an abnormal state. That is, it is determined that an abnormal state occurs when communication deviating from a daily traffic pattern formed in the past occurs. As an example of an abnormal state, the traffic pattern in the daytime zone is flat with no decrease in the amount of communication data, but the amount of communication data in the wireless communication means 21 in the daytime zone is that of the traffic pattern. Is different.

  The home appliance control means 23 controls an external home appliance when the determination means 32 determines that the state is abnormal. Moreover, the home appliance control means 23 holds one of the home mode and the absent mode, and switches to the other mode using the determination of the abnormal state as a trigger. For example, when the home appliance control unit 23 is in the home mode, if the determination unit 32 determines that it is in an abnormal state, the home appliance control unit 23 switches to the absence mode.

  The household appliance control means 23 controls each household appliance based on the setting information of the household appliance set by the setting means 33 mentioned later at the time of this mode switching. For example, when switching from home mode to unattended mode, 1F illumination 1 and 2F illumination 2 are turned off and 1F intrusion detector 5 and 2F intrusion detector 6 are turned on, or when switching from unattended mode to home mode, 1F air conditioners 3 and 2F Turn on the air conditioner 4.

  The setting means 33 holds the setting information of the home appliance in the home mode when there is a person in the house and the setting information of the home appliance in the unattended mode when there is no person in the house. The home appliance setting information includes a home appliance to be controlled and information to be set for the home appliance. For example, an example of the setting information is information that the 1F illumination 1 is turned on in the home mode. The home appliance control means 23 interprets this information and transmits a control signal to the home appliance to be controlled via the home controller 7 to change the state of the home appliance.

Next, the initial setting of the home appliance control system will be described with reference to FIGS. The initial setting is performed for the following three items.
(1) Identification of devices that generate interference radio waves (2) Definition of home appliance setting information (3) Traffic pattern formation

  FIG. 3 is a diagram illustrating a relationship between radio waves in a specific frequency band and interference radio waves. FIG. 3A shows the frequency band (Hz) of the radio wave used by the wireless communication means 21 of the home appliance control device 20 and the intensity of the radio wave. The wireless communication means 21 uses radio waves of a plurality of channels in the 2.4 GHz band, and six of them are illustrated. The bandwidth of these channels is 5 MHz.

  When the interference detection means 22 detects that there is a radio wave that interferes with these channels, it searches the database to identify which home appliance has the frequency band of the interference radio wave. FIG. 3B shows an example of this database. As shown in the drawing, the database stores the name of the home appliance, the used bandwidth and the occupied bandwidth of the radio wave used by the home appliance. For example, if the frequency band of the interference radio wave is 2.450 to 2.500 GHz, it is searched whether or not the frequency band is registered in the occupied band of this database. As a result, it can be seen that the frequency band is that of a microwave oven. Then, from the occupied band and the used bandwidth, the radio wave of the microwave oven interferes with a part of the sixth channel (6ch) used by the wireless communication means 21 (the part indicated by a in the figure). Record it. As a result, the initial setting that the radio wave that interferes with a part of the sixth channel is interference by the microwave oven is performed.

  In FIG. 4A, setting information about the home appliance on the first floor of the house is set, and in FIG. 4B, setting information about the home appliance on the second floor is set visually via, for example, a web browser or the like. The screen image when doing is shown.

  As shown in FIG. 4A, in the home mode, 1F illumination 1, 1F air conditioner 3 is set to ON, and 1F intrusion detector 5 is set to OFF. In the absence mode, the 1F illumination 1 and the 1F air conditioner 3 are turned off and the 1F intrusion detector 5 is turned on.

  As shown in FIG. 4B, in the home mode, the 2F illumination 2 and the 2F air conditioner 4 are turned on and the 2F intrusion detector 6 is turned off. In the absence mode, the 2F illumination 2 and the 2F air conditioner 4 are turned off and the 2F intrusion detector 6 is turned on.

  The setting information of each home appliance is stored in the home server 30 via such a setting screen.

  Next, a traffic pattern is formed. Specifically, the home appliance control device 20 is operated for a certain period, for example, for one week, and information on the amount of communication data at that time is transmitted to the home server 30. The home server 30 accumulates the communication data amount information and the reception time to form a traffic pattern. This traffic pattern is shown in FIG. As shown in FIG. 5, a traffic pattern at the time of staying at home on the first floor is formed in FIG. A decrease in the amount of communication data occurs at times T1 and T2, which is a decrease in traffic due to interference radio waves. For example, at time T1, since the microwave oven 10 is operated, the amount of communication data is reduced due to the interference radio waves. Further, at time T2, since an interference radio wave is generated by the base unit 8, the amount of communication data due to the interference radio wave is reduced.

  If the user's life rhythm is regular to some extent, it is considered that the same decrease in the amount of communication data is recorded even if the day is changed. From this, it can be considered that the traffic pattern represents a rhythm of life such as “when to operate the microwave oven 10”, “when to make a telephone call”. Then, as described later, when a communication data amount deviating from the traffic pattern occurs, it is determined that the abnormal state deviates from the daily life rhythm.

  FIG. 5B illustrates an absent traffic pattern on the first floor. Since the absent traffic pattern does not cause interference radio waves because the user does not operate the microwave oven 10 or the like, a flat traffic pattern is formed without causing a decrease in the amount of communication data.

  Hereinafter, similarly, FIG. 5C illustrates a home traffic pattern on the second floor. In this home traffic pattern, the communication data amount is reduced due to the interference radio wave at time T3 and time T4. From this, it can be considered that an action such as “calling with the handset 9” is performed on a daily basis at the time T3 and the time T4. In addition, FIG. 5D illustrates an absent traffic pattern on the second floor, and a flat traffic pattern is formed as in the first floor.

  Next, the process flow in the household appliance control system which performed said initial setting is demonstrated. FIG. 6 is a process flow of the home appliance control system according to the present embodiment. As shown in the figure, first, the home appliance control device 20 performs mode initialization (step S1). That is, either the home mode or the absent mode is set. Here, it is assumed that the absence mode is set.

  Next, the home appliance control device 20 detects an interference radio wave while functioning as a wireless LAN router (step S2). If an interference radio wave is detected, the amount of communication data decreases due to the interference, and information on the amount of communication data at that time is transmitted to the home server 30 (step S3).

  Upon receiving the communication data amount information (communication data amount A), the home server 30 compares the received data with the communication data amount (communication data amount B) of the absent traffic pattern at the same time (step S4). As a result of the comparison, if it is not an abnormal state (step S5; No), the home appliance control device 20 maintains the current absence mode state (step S6), and if the communication data amount A and B are different, the abnormal state (Step S5; Yes).

  For example, in step S6, as shown in FIG. 7A, it is determined that the communication data amount X actually obtained by the wireless communication means 21 has a value different from the absent traffic pattern, and is determined as an abnormal state. .

  As described above, the home appliance control device 20 is changed to the home mode, triggered by the fact that the communication deviating from the absent traffic pattern is performed in spite of the absence mode (step S7). Communication that deviates from such an absent traffic pattern means that, for example, a person has operated the microwave oven 10 or the like on the first floor, and that the first floor is not at home but at home. It is synonymous with. As a result, the home appliance control device 20 can be automatically switched from the absence mode to the home mode.

  Thereafter, the home server 30 transmits the home appliance setting information (step S8). Next, the home appliance control device 20 changes to the home mode (step S9), and controls the home appliance based on the setting information of the home appliance received from the home server 30 (step S10).

  For example, since it is determined in step S6 that the abnormal state is present in the absence mode, the 1F illumination 1 is turned on, the 1F air conditioner 3 is turned on, and the 1F intrusion detector 5 is turned off as shown in the home mode in FIG. Control to turn on.

  The above processing is similarly performed for the second floor absent traffic pattern, and the abnormal state is determined. If the home server 30 is in an abnormal state, the home appliance setting information as shown in FIG. It transmits to the household appliance control apparatus 20, and the household appliance control apparatus 20 controls each household appliance based on this setting information.

  In the home mode, the home server 30 determines whether or not a communication data amount deviating from the home traffic pattern has occurred. For example, as shown in FIG. 7B, it is determined that the communication data amount Y actually obtained by the wireless communication means 21 has a value different from the home traffic pattern, and is determined as an abnormal state. Thereafter, the home appliance control device 20 is changed to the absence mode, and setting information (see FIG. 4A) of the home appliance for the absence mode is transmitted to the home appliance control device 20, and the home appliance control device 20 is based on this setting information. Control each home appliance.

  As described above, when the traffic pattern and the setting information to be set for the home appliance are defined in advance and the home appliance control device 20 detects the interference radio wave, the decrease in the communication data amount due to the interference radio wave deviates from the traffic pattern. The home server 30 determines whether or not the home appliance has been used, and the home appliance control device 20 controls the home appliance according to the setting information so that each home appliance is in an appropriate state based on the result.

  In the home appliance control system according to the present invention, the user automatically controls home appliances based on the presence or absence of interference radio waves generated as a result of normal use of home appliances by the user. Is not bothered by Further, since the traffic pattern is formed in advance, the home appliance can be controlled in accordance with the life pattern of the user. For example, if a preset traffic pattern is used, home appliances are improperly controlled due to misjudgment, but the home appliance control system according to the present invention does not have such a misjudgment according to the user. Control of home appliances with a small amount is performed.

  Moreover, since all the household appliances can be centrally managed by the household appliance control apparatus 20 and the home server 30 based on the traffic pattern, the management burden can be reduced. Furthermore, since an existing wireless LAN router has only to have a home appliance control function, there is no cost for newly installing a special device, and the introduction cost can be reduced.

  In the present embodiment, the home appliance control device 20 and the home server 30 share each function. However, the present invention is not necessarily limited to such an embodiment, and the home appliance control device 20 alone may perform all functions. Good. That is, the home appliance control device 20 may further include a traffic pattern forming unit, a determining unit, and a setting unit.
