The communication control unit 240 generates a signal for controlling the transmission / reception unit 220 and processes information output from the transmission / reception unit 220. The signal generation unit 242 generates a signal for controlling each unit of the server 128 and other signals. The signal generator 242 also generates a signal for controlling the personal computer 104 and other devices connected via the transmission / reception unit 220.

  Referring to FIG. 5, the program executed on communication terminal 70 performs the following control regarding teaching.

  In step S300, the user who wants to perform teaching stands with the communication terminal 70 in a place where the communication terminal 70 is to transmit the device information, and the key operation unit according to a procedure predetermined by the manufacturer of the communication terminal 70. 136 is operated. The key operation unit 136 generates a signal corresponding to this operation. The generated signal is output to the teaching control unit 184. When this signal is input, the teaching control unit 184 controls the display unit 138. The display unit 138 displays information that prompts input of a message according to the control of the teaching control unit 184.

  The user who sees this information inputs information indicating the device to be activated by operating the key operation unit 136. When the information is input, the key operation unit 136 generates a signal corresponding to the information. The generated signal is output to the teaching control unit 184. The teaching control unit 184 stores information corresponding to the generated signal in the memory 142. As a result, information indicating the device to be activated is stored in the memory 142.

  In the case of the present embodiment, information indicating the device to be activated is stored in a predetermined area of the memory 142. In the present embodiment, this area is referred to as a “reference area”. The address where the information is stored corresponds to the order in which the information is stored. Thus, the information indicating the device to be activated stored in the reference area is also stored in the memory 142 as information indicating the input order of the information indicating the device as a whole.

  When information indicating the device is stored in the memory 142, the teaching control unit 184 controls the detection unit 190. The detection unit 190 detects the time according to the control of the teaching control unit 184. The information indicating the detected time is stored in an address having a predetermined relationship with the address in which the information indicating the device is stored in the reference area of the memory 142. Thereby, the time information is stored in association with the information indicating the device.

  When the time information is stored, the teaching control unit 184 controls the display unit 138. The display unit 138 displays information that prompts input of information indicating the current position of the communication terminal 70 according to the control of the teaching control unit 184.

  The operator who sees this information inputs information indicating the current position of the communication terminal 70 by operating the key operation unit 136. When the information is input, the key operation unit 136 generates a signal corresponding to this information. The generated signal is output to the teaching control unit 184. The teaching control unit 184 stores information corresponding to the generated signal in the reference area of the memory 142. As a result, the position information is stored in the memory 142. The position information is also associated with information indicating the device, as is the time information.

  In the case of the present embodiment, as with the information indicating the device, the address where the position information is stored also corresponds to the order in which the information is stored. In addition, the position information stored in the reference area is read according to the order of the addresses where the position information is stored. As a result, the position information stored in the reference area constitutes information representing the reference route as a whole.

  In step S 302, base station antenna 130 receives radio waves from first base station 72, second base station 74, and third base station 76. The radio wave is converted into an electric signal by the base station antenna 130 and output to the base station demodulation unit 160. The measurement control unit 212 controls the base station demodulation unit 160. The base station demodulator 160 is an electric signal representing the radio wave from the first base station 72, an electric signal representing the radio wave from the second base station 74, and an electric signal representing the radio wave from the third base station 76. Are sequentially output to the measurement unit 162. The measuring unit 162 sequentially measures the strength of these radio waves and generates intensity information. The intensity information is output to the teaching control unit 184.

  The LAN antenna 131 receives radio waves from the access point. The radio wave is converted into an electric signal by the LAN antenna 131 and output to the LAN demodulator 166. The extraction control unit 210 controls the LAN demodulation unit 166. LAN demodulator 166 sequentially outputs electrical signals representing radio waves from the access point to measuring unit 162. This signal indicates the SSID. This signal is output to the teaching control unit 184.

  In step S <b> 304, the teaching control unit 184 stores the strength information and the identification information indicating the SSID in the reference area of the memory 142. These pieces of information are stored in an address having a predetermined relationship with the address where the information stored in step S300 is stored. As a result, these pieces of information are stored in association with the information stored in step S300. By associating these pieces of information with the information stored in step S300, the information stored in the reference area is not only used as information indicating the input order of information indicating the device, but also as the element information acquisition order. The information to be represented is also stored in the memory 142.

  In step S306, teaching control unit 184 determines whether there are two or more identical combinations among the combinations of identification information stored in memory 142. If it is determined that there are two or more sets (YES in step S306), the process proceeds to step S308. If not (NO in step S306), the process ends. In step S308, the teaching control unit 184 deletes the identification information stored in step S304 from the combination of identification information stored in the memory 142.

  Referring to FIG. 6, the program executed by communication terminal 70 performs the following control regarding transmission of device information.

  In step S320, base station antenna 130 receives radio waves from first base station 72, second base station 74, and third base station 76. The radio wave is converted into an electric signal by the base station antenna 130 and output to the base station demodulation unit 160. The measurement control unit 212 controls the base station demodulation unit 160. The base station demodulator 160 is controlled by the measurement control unit 212 to generate an electric signal representing a radio wave from the first base station 72, an electric signal representing a radio wave from the second base station 74, and a third base station. The electric signal representing the radio wave from 76 is sequentially output to the measuring unit 162. The measuring unit 162 sequentially measures the strength of these radio waves and generates intensity information. The intensity information is output to the selection unit 192.

  The LAN antenna 131 receives radio waves from the access point. The radio wave is converted into an electric signal by the LAN antenna 131 and output to the LAN demodulator 166. The extraction control unit 210 controls the LAN demodulation unit 166. The LAN demodulator 166 sequentially outputs electrical signals representing radio waves from the access point to the measuring unit 162 under the control of the extraction controller 210. This signal indicates the SSID. This signal is also output to the selection unit 192.

  In step S322, the selection unit 192 collates the combination of intensity information and identification information input in step S320 with the combination of intensity information and identification information stored in the memory 142.

  In step S324, the selection unit 192 includes at least one of the combination of intensity information and the combination of identification information input in step S320, and at least one of the combination of intensity information and the combination of identification information stored in the memory 142. It is judged whether or not. In the case of the present embodiment, after selecting whether or not the combination of identification information matches, the selection unit 192 determines whether or not the combination of intensity information matches if the combination does not match. When determining whether or not the combination of intensity information matches, even if the intensity of the radio wave indicated by the intensity information does not completely match, the intensity difference for any radio wave is within the allowable range. , It is determined that the combination of intensity information matches. If it is determined that they match (YES in step S324), the process proceeds to step S326. If not (NO in step S324), the process ends.

  In step S326, selection unit 192 reads the next information. The first information is position information corresponding to the combination of intensity information or the combination of identification information input in step S320 among the information stored in the reference area of the memory 142. The second information is the above-described “information representing a reference route”. In the reference area of the memory 142, the first information is a part of the second information, but the selection unit 192 reads the first information separately from the second information. The third information is information representing a route followed by the user holding the communication terminal 70 while performing this step. This information is stored in the path area of the memory 142. The route area will be described later. The first information, the second information, and the third information are copied to a buffer (not shown) built in the selection unit 192. When these pieces of information are copied, the selection unit 192 deletes a portion that matches the third information from the second information described above. If the third information is not stored, the second information is not deleted. The portion of the second information that has not been deleted means a place where the user holding the communication terminal 70 has not yet arrived. Thereby, the selection part 192 can identify those places. When those locations are identified, the selection unit 192 identifies a location that should arrive first among locations that have not yet arrived, based on the remaining portion of the second information that has not been deleted. . Since these pieces of information correspond to the element information acquisition order and the device information input order, it is possible to specify the location based on these pieces of information. When the location is specified, the selection unit 192 compares the information representing the location with the first information described above. If these pieces of information match, it means that the route of the user holding the communication terminal 70 matches the reference route. Based on the result, the selection unit 192 determines whether or not the route of the user holding the communication terminal 70 matches the reference route. If it is determined that they match (YES in step S326), the process proceeds to step S328. Otherwise (NO in step S326), the process proceeds to step S336.

  In step S328, selection unit 192 copies the first information to the path area of memory 142. The “route area” means an area for storing the position information stored as the first information described above in the buffer of the selection unit 192 when performing the process of step S326. The address where the position information is stored corresponds to the order in which the information is stored. Also, information representing the user's route stored in the route area is read according to the order of the addresses where the position information is stored. Thus, the position information stored in the route area constitutes information representing the route of the user holding the communication terminal 70 as a whole.

  In step S330, selection unit 192 controls detection unit 190. The detection unit 190 detects time according to the control of the selection unit 192.

  In step S332, the selection unit 192 reads information indicating the device to be activated corresponding to the element information determined to match in step S324. When the information is read, the selection unit 192 stores the information as device information in a buffer (not shown) built therein. When the device information is stored, the selection unit 192 creates information communicated as an email. Information communicated as mail includes device information.

  In step S334, selection unit 192 outputs information communicated as a mail to transmission / reception unit 132. When the information is output, the mail transmission unit 194 controls the base station antenna 130 and the transmission / reception unit 132. The base station antenna 130 and the transmission / reception unit 132 transmit mail to the base station with which communication has been established under the control of the mail transmission unit 194. The mail destination is the server 128. In this embodiment, the mail address of the server 128 is stored in the memory 142 in advance. The base station transmits the mail to the PHS connection device 120. The PHS connection device 120 transmits the mail to the local exchange 122. The local exchange 122 transmits the mail to the local exchange 126 according to the control of the central control station 124. The local exchange 126 transmits the mail to the server 128.

  FIG. 7 is a diagram showing the format of the mail communicated at this time. This mail format includes an area including information on the transmission source, an area including information on the data size, an area including information on the transmission time, that is, the time detected by the detection unit 190 in step S330, and information on the transmission destination. And a region including device information.

  In step S336, selection unit 192 deletes all information stored in the path area of memory 142.

  Referring to FIG. 8, the program executed by server 128 executes the following control with respect to transmission of the control signal.

  In step S340, public communication unit 244 of transmission / reception unit 220 receives mail from local exchange 126. This mail is assumed to be a mail transmitted by the communication terminal 70. The communication control unit 240 temporarily stores the device information included in the received mail in a buffer built therein.

  In step S342, communication control unit 240 reads information corresponding to the device information received in step S340 from among the information representing the control signal stored in memory 228. When the information is read, the communication control unit 240 outputs the information to the signal generation unit 242. The signal generation unit 242 generates a control signal based on the information. The signal generation unit 242 outputs the generated control signal to the communication control unit 240. The communication control unit 240 controls the local communication unit 246 of the transmission / reception unit 220. The local communication unit 246 transmits the control signal to the personal computer 104 or the like according to the control of the communication control unit 240.

  An operation of communication terminal 70 based on the above-described structure and flowchart will be described.

[Teaching]
The user holds the communication terminal 70 and stands in front of the home 64 and inputs information indicating a device to be activated and position information. The memory 142 stores such information and time (step S300).

  When information indicating the device to be activated is stored, the base station antenna 130 receives radio waves from the first base station 72, the second base station 74, and the third base station 76. To do. The measuring unit 162 sequentially measures the strength of these radio waves and generates intensity information. The LAN antenna 131 tries to receive radio waves from the nearest access point, but cannot receive radio waves because there is no access point that transmits radio waves (step S302).

  When the strength information is acquired, the memory 142 stores information indicating the device to be activated and the strength information in association with each other (step S304).

  When the intensity information or the like is stored, the teaching control unit 184 determines whether or not two or more identical combinations exist among the combinations of identification information stored in the memory 142 (step S306). In this case, if there are no two or more sets of identification information (NO in step S306), teaching in front of home 64 ends.

  After that, the user stands with the communication terminal 70 in front of the convenience store 56 and inputs information indicating a device to be activated and the current position. Thereafter, through the process of step S300, the base station antenna 130 receives radio waves from the first base station 72, the second base station 74, and the third base station 76. The measuring unit 162 sequentially measures the strength of these radio waves and generates intensity information. The LAN antenna 131 receives radio waves from the access point. The LAN demodulator 166 extracts an electrical signal representing the SSID from the radio wave. Thereby, the identification information is also extracted (step S302).

  When the strength information and the identification information are acquired, the memory 142 stores the strength information, the identification information indicating the SSID, the information indicating the device to be activated, the time, and the current position in association with each other (step S304). Thereafter, the process of step S306 is repeated. Thereby, teaching in front of the convenience store 56 is completed.

  Thereafter, the user stands with the communication terminal 70 in front of the station 54 and inputs information indicating the device to be activated and the current position. Thereafter, the processing from step S300 to step S304 is repeated. When the process of step S304 ends, the teaching control unit 184 determines whether there are two or more identical combinations among the combinations of identification information stored in the memory 142 (step S306). In this case, the last stored identification information is information transmitted by an access point installed at the station 54. This information is different from the combination of information received during teaching in front of the convenience store 56. Thus, if there are not two or more identical combinations among the combinations of identification information stored in memory 142 (NO in step S306), teaching in front of station 54 ends.

  In the case of the present embodiment, after that, the user repeats the same teaching in front of the commercial building 52.

  FIG. 9 is a conceptual diagram showing information stored in the reference area of the result memory 142 after several teachings. As is clear from FIG. 9, in the case of the present embodiment, the reference area of the memory 142 can store the SSIDs of up to five access points and the radio wave intensity of up to five base stations as intensity information. It goes without saying that the number of access points that can store SSIDs and the number of base stations that can store the intensity of radio waves may be larger or smaller than this. However, it is desirable that the intensity of radio waves from at least three base stations can be stored. This is because the location can be determined with high accuracy by determining the location of the communication terminal 70 and, therefore, the person who owns it based on the intensity of the radio waves at least at three locations.

[When starting the device]
It is assumed that the user having the communication terminal 70 leaves the home 64 shown in FIG. 1 and heads for the commercial building 52 in which the office is located. The base station antenna 130 receives radio waves from the first base station 72, the second base station 74, and the third base station 76. The measuring unit 162 sequentially measures the strength of these radio waves and generates intensity information. The LAN antenna 131 tries to receive radio waves from the nearest access point, but cannot receive radio waves because there is no access point that transmits radio waves (step S320).

  When the intensity information is acquired, the selection unit 192 collates the combination of intensity information input in step S320 with the combination of intensity information stored in the memory 142 (step S322).

  When collation is completed, the selection unit 192 determines whether or not the combination of intensity information input in step S320 matches the combination of intensity information stored in the memory 142 (step S324). In this case, if the intensity difference between the combination of received radio wave intensity and the combination of intensity information stored in the memory 142 is within the allowable range for any radio wave (in step S324). YES), the selection unit 192 reads the following information. The first information is position information corresponding to the combination of the intensity information input in step S320 among the information stored in the reference area of the memory 142. The second information is the above-described “information representing a reference route”. The third information is information representing a route followed by the user holding the communication terminal 70 while performing this step.

  In this case, the content of the first information is information “in front of home”. When the first information is read, the selection unit 192 determines whether or not the route of the user holding the communication terminal 70 matches the reference route (step S326). In this case, among the places that have not yet arrived, the place that should arrive first is “in front of home”, and the content of the first information described above is “in front of home” (YES in step S326). The unit 192 adds position information to the route area of the memory 142 (step S328).

  When the position information is added, the detection unit 190 detects the time according to the control of the selection unit 192 (step S330).

  When the time is detected, the selection unit 192 reads, from the reference area of the memory 142, information indicating the device to be activated, corresponding to the element information determined to match in step S324. When the information is read, the selection unit 192 creates information communicated as an email (step S332). The device information included in the information communicated as mail at this time is information “printer”. When information to be communicated as a mail is created, the base station antenna 130 and the transmission / reception unit 132 transmit a mail addressed to the server 128 to the base station with which communication is established, under the control of the mail transmission unit 194. (Step S334).

  When the mail is transmitted, the public communication unit 244 of the server 128 receives the mail (step S340). When the mail is received, the communication control unit 240 causes the local communication unit 246 of the transmission / reception unit 220 to transmit a control signal corresponding to the device information among the information representing the control signal stored in the memory 228 (step S342). As a result, the printer 106 starts the activation process.

  As described above, when the communication terminal 70 according to the present embodiment arrives at or passes through a predetermined location, the route to reach or pass through the location is appropriate. Only in such a case, a mail is transmitted to the server 128. As a result, the device connected to the server 128 starts the activation process in the order corresponding to the path of the communication terminal 70. Since the activation processing is performed in such an order, if teaching is performed so that device information is transmitted at an appropriate place, the device can be easily activated at an appropriate timing. When a device is activated at an appropriate timing, power consumption while the device is on standby is minimized. As a result, it is possible to provide a device control system that can start the use of a plurality of devices at an optimal timing without consuming much power consumption.

  Further, when the identification information extracted from the received radio wave matches the identification information stored in the memory 142, the communication terminal 70 according to the present embodiment transmits device information corresponding to the identification information. Whether or not the identification information matches the radio wave intensity is clearly determined. As a result, the possibility that the actual location of the person holding the communication terminal 70 is different from the location specified based on the identification information is considerably reduced.

  Further, when the received identification information matches the identification information stored in the memory 142, the communication terminal 70 according to the present embodiment transmits device information to the base station. A space capable of communicating with one access point is generally smaller than a space capable of communicating with one base station. The same can be said when the intensity at the transmission source of the radio wave used for location determination is lower than that of the radio wave used for transmission of device information, not limited to the access point. In this case, the error related to the location is greatly reduced as compared with the case where the determination is made using the base station. On the other hand, it is not easy to communicate with the server 128 quickly using an access point compared to communication using a base station. This is because login and other procedures for using the access point are necessary. When a mail is transmitted using a base station like the communication terminal 70, rapid communication becomes possible. As a result, it is possible to provide a device control system that can quickly implement highly accurate control.

  In addition, the communication terminal 70 according to the present embodiment displays the device information when the intensity difference is within the allowable range between the received radio wave intensity and the radio wave intensity stored in the memory 142. Send. The area where radio waves that do not represent identification information are transmitted is extremely wide compared to areas where radio waves that represent such information are transmitted. As a result, when the location of the person holding the communication terminal 70 is determined based on the strength of the radio wave, the message can be sent at a variety of locations compared to the case where the location of the person holding the communication terminal 70 is determined based on the identification information. Can be sent. As a result, it is possible to provide a device control system that can control devices at various timings.

  As a first modification, in step S334, the mail transmission unit 194 may control the LAN antenna 131 and the transmission / reception unit 132. In this case, a mail generated by the selection unit 192 and destined for the server 128 is transmitted as a pseudo mail using the Internet. FIG. 10 is a conceptual diagram showing a route between device information and a control signal in this modification. FIG. 11 is a conceptual diagram showing a path between device information and a control signal when the device control system according to this modification is applied to a home appliance. Incidentally, similarly to the modification example shown in FIG. 11, in the device control system shown in FIG. 2, the server 128 cannot transmit the control signal directly to the device that transmits the infrared signal, so that it cannot be directly connected to the network. The device may be indirectly controlled. In this case, the infrared transmitting device transmits the infrared signal to a receiving device that receives a control signal from the server 128, a storage device that stores information that the infrared signal should include, and a device that cannot be directly connected to the network. A transmission device.

  As a second modification, the communication terminal 70 may be a mobile phone or other communication terminal.

  As a third modification, an ESSID (Extended Service Set Identifier) may be used instead of the SSID.

  As a fourth modified example, when the combination of the acquired element information matches the combination of the element information stored in the memory 142, the communication terminal 70 regardless of the path of the communication terminal 70 up to that point. Instead, information indicating the device to be activated corresponding to the combination of the element information may be transmitted.

  As a fifth modification, the communication terminal 70 may determine whether or not one type of element information matches instead of determining whether or not the combination of element information matches. Furthermore, instead of determining whether or not the element information matches as described in step S324, the communication terminal 70 determines whether the connection with the access point has been established or the connection with the access point is disconnected. It may be determined whether or not. In this case, the determination may be performed based on whether or not a certain period of time has elapsed after connection or whether or not a certain period of time has elapsed after disconnection. Furthermore, the server 128 may transmit a control signal in response to receiving device information from a plurality of generation communication terminals 70 instead of receiving device information from one communication terminal 70.

  As a sixth modification, when the device information received from the communication terminal 70 represents the server 128 itself, the server 128 may perform an operation according to the reception of the device information. An example of such an operation is a backup of information stored in the server 128, for example.

  As a seventh modification, the personal computer 104 and other devices may have the functions handled by the server 128. In this case, the mail transmitted by the communication terminal 70 is directly received by each of the devices, and the device that is determined to be the mail addressed to itself performs the operation corresponding to the device information by the operation execution unit that each device has. It will be.
