  Hereinafter, a first embodiment and a second embodiment of the present invention will be described with reference to the drawings.

[First Embodiment]
For example, as shown in FIG. 1, the present invention is applied to a wireless communication system including a master device 10 and a slave device 20. The master device 10 and the slave device 20 in this wireless communication system can perform device registration processing, which will be described later, and perform transmission / reception of various application data by performing communication in conformity with the same short-range wireless communication standard. Become. An example of the short-range wireless communication standard common to the master device 10 and the slave device 20 is Bluetooth (registered trademark). In this short-range wireless communication, transmission is performed with a transmission power of 1 mW (power class 2) by the master device 10 and the slave device 20, thereby performing communication over a communication distance of about 10 m at maximum.

  This wireless communication system performs, for example, a device registration process for registering a communication partner when establishing a short-range wireless communication connection compliant with Bluetooth (registered trademark) between a master device 10 and a slave device 20. The device 10 and the slave device 20 controlled by the master device 10 can constitute a piconet in which seven slave devices 20 can be communicably connected to a single master device 10. Here, the communication device that starts the device registration process is the master device 10, and the communication device that is registered according to the device registration process started by the master device 10 is the slave device 20. Then, the master device 10 and the slave device 20 that have performed the device registration process can perform wireless communication only by entering the mutual communication range.

[Configuration of wireless communication system]
The master device 10 and the slave device 20 have substantially the same configuration, and perform communication processing for transmitting and receiving wireless signals to each other and various application processing. That is, the master device 10 includes an antenna 11, an RF processing unit 12, a baseband processing unit 13, a CPU (Central Processing Unit) 14 for short-range wireless communication, a main CPU 15, a RAM (Random Access Memory) 16, an EEPROM (Electrically Erasable and A Programmable Read Only Memory) 17, a display unit 18, and an operation input unit 19 are provided. The slave device 20 is similar to the units 11 to 19 of the master device 10, and includes an antenna 21, an RF processing unit 22, a baseband processing unit 23, a short-range wireless communication CPU 24, a main CPU 25, a RAM 26, an EEPROM 27, and a display unit 28. And an operation input unit 29.

  The antenna 11 and the antenna 21 transmit a radio wave when a radio signal is supplied from the RF processing unit 12 and the RF processing unit 22, and receive the radio wave and convert it into an electric radio signal to convert the radio signal into an RF processing unit 12 and output to the RF processing unit 22.

  The RF processing unit 12 and the RF processing unit 22 perform lower layer processing in the near field communication standard. The RF processing unit 12 and the RF processing unit 22 perform frequency spread processing and modulation processing on data from the baseband processing unit 13 and the baseband processing unit 23 when transmitting radio waves from the antenna 11 and antenna 21. To create a radio signal. In addition, when a radio signal received by the antenna 11 or the antenna 21 is input, the RF processing unit 12 and the RF processing unit 22 perform demodulation processing on the radio signal to perform the near field communication CPU 14 and the near field wireless communication. Output to the communication CPU 24.

  The baseband processing unit 13 and the baseband processing unit 23 perform baseband processing as lower layer processing in the short-range wireless communication standard. In other words, the baseband processing unit 13 and the baseband processing unit 23, when transmitting radio waves from the antenna 11 and antenna 21, include data such as a header in the data from the CPU 14 for short-range wireless communication and the CPU 24 for short-range wireless communication. Baseband processing for adding control information and controlling the output timing to the RF processing unit 12 and the RF processing unit 22 is performed. In addition, when a radio signal that is packet data is input from the RF processing unit 12 and the RF processing unit 22, the baseband processing unit 13 and the baseband processing unit 23 perform baseband processing for extracting data from the packet data. And output to the short-range wireless communication CPU 14 and the short-range wireless communication CPU 24.

  The short-range wireless communication CPU 14 and the short-range wireless communication CPU 24 perform upper layer processing in the short-range wireless communication standard. That is, the short-range wireless communication CPU 14 and the short-range wireless communication CPU 24 read out and execute a program describing a processing procedure compliant with the short-range wireless communication standard stored in the EEPROM 17 and also execute the communication stored in the EEPROM 17. Data is used to perform protocol processing, profile processing, and the like according to communication procedures including device registration processing and communication establishment processing described later.

  Thereby, the CPU 14 for near field communication and the CPU 24 for near field communication receive application data to be transmitted from the main CPU 15 and the main CPU 25 in a state where the communication connection between the master device 10 and the slave device 20 is established. In this case, the application data is output to the short-range wireless communication CPU 14 and the short-range wireless communication CPU 24, and when the received data is input from the short-range wireless communication CPU 14 and the short-range wireless communication CPU 24, the data is output. The data is output to the main CPU 15 and the main CPU 25.

  The main CPU 15 and the main CPU 25 perform application processing by executing application programs stored in the EEPROM 17. When the main CPU 15 and the main CPU 25 transmit wireless radio waves, the main CPU 15 and the main CPU 25 output the generated application data to the CPU 14 for short-range wireless communication and the CPU 24 for short-range wireless communication, and the CPU 14 for short-range wireless communication and the short-range wireless communication. When data is input from the communication CPU 24, application processing using the data is performed. Further, the main CPU 15 and the main CPU 25 output display data to the display unit 18 and the display unit 28 in order to display various contents of application processing and communication processing by the CPU 14 for short-range wireless communication and CPU 24 for short-range wireless communication. Furthermore, when the operation input signal is input from the operation input unit 19 or the operation input unit 29, the main CPU 15 or the main CPU 25 performs application processing according to the operation input signal or is in the middle of communication processing. The operation input signal is output to the short-range wireless communication CPU 14 and the short-range wireless communication CPU 24.

  In the wireless communication system shown in FIG. 1, the short-range wireless communication CPU 14 and short-range wireless communication CPU 24 that perform communication processing, and the main CPU 15 and main CPU 25 that perform application processing are configured separately. When the capability is high, the short-range wireless communication CPU 14 and the main CPU 15 may be configured by a single CPU, and the short-range wireless communication CPU 24 and the main CPU 25 may be configured by a single CPU. .

  The RAM 16 and RAM 26 function as a work area when the master device 10 and the slave device 20 perform application processing and communication processing, and various information is temporarily stored by the main CPU 15 and the main CPU 25.

  The EEPROM 17 and the EEPROM 27 store an application program, a communication program for performing processing conforming to the short-range wireless communication standard, and various data for performing application processing and communication processing.

  The display unit 18 and the display unit 28 input display data from the main CPU 15 and the main CPU 25 and present them to the user by displaying various types of information in application processing and communication processing.

  When the operation input unit 19 and the operation input unit 29 detect a user operation, the operation input unit 19 and the operation input unit 29 output an operation input signal indicating the operation content to the main CPU 15 and the main CPU 25.

  The master device 10 and the slave device 20 configured in this manner are used to distinguish the slave device 20 from communication devices compliant with other short-range wireless communication standards by the master device 10 before transmitting / receiving application data. Then, a device registration process for registering a device address that is address information (identification information) unique to the slave device 20 and a device name that is a name (identification information) unique to the slave device 20 is performed. The device address acquired by the device registration process is included in the header as a destination address by the short-range wireless communication CPU 14 when sending a radio wave, and the device name is short-range wireless communication CPU 14 when sending the radio wave. Is included in the header as identification information.

[Device registration processing by wireless communication system]
Next, device registration processing in the above-described wireless communication system will be described.

  First, as shown in FIG. 2A, when the user operates the operation input unit 19 of the master device 10, a device registration screen including a device registration button 31 is displayed on the display screen 18 a of the display unit 18. When the user operates the operation input unit 19 to detect an operation input signal indicating that the device registration button 31 is selected by the main CPU 15 (step S1), the main CPU 15 displays a display screen as shown in FIG. In 18a, the device name input screen including the device name input field 32 and the enter button 33 of the slave device 20 is changed to be displayed.

  Then, when the operation input unit 19 is operated by the user, an operation input signal for inputting the device name of the slave device 20 “XXXX” in the device name input field 32 is detected, and then the determination input button 33 is selected. Is detected by the main CPU 15 (step S2), device registration processing by the short-range wireless communication CPU 14 is started (step S3). Here, the main CPU 15 temporarily stores the device name “XXXX” input by the user in the RAM 16.

  Then, when the process proceeds to step S3 in FIG. 2, the short-range wireless communication CPU 14 determines in step S11 in FIG. 3 that the user has input the device name of the slave device 20, and performs the process in step S12. Proceed.

  Next, the CPU 14 for short-range wireless communication performs an inquiry process for obtaining a device address from the slave device 20 in step S12.

  At this time, as shown in FIG. 4A, a communication device that performs communication processing in accordance with the same short-range wireless communication standard as the master device 10, and the communication device that is the slave device 20 for the master device 10 is 20A, When there are three units 20B and 20C, the master device 10 transmits radio waves including a command for returning a device address to the respective communication devices 20A, 20B, and 20C. At this time, the baseband processing unit 13 stores an inquiry command (Inquiry) in the data area of the packet data, and operates the RF processing unit 12 and the antenna 11 to transmit radio waves.

  On the other hand, when the slave device 20 which is the communication device 20A is in the inquiry scan (Inquiry Scan) state in which the inquiry command is waiting, the slave device 20A sends a response corresponding to the inquiry radio wave to the master device 10. Reply to At this time, when the packet data including the inquiry command is input, the slave device 20A reads the device address from the EEPROM 27 and creates a response packet including the device address. Then, the slave device 20A operates the baseband processing unit 23, the RF processing unit 22, and the antenna 21 to transmit radio waves.

  When the master device 10 receives a response to the inquiry command from the slave device 20A, the baseband processing unit 13 extracts the device address of the slave device 20A from the packet data, and temporarily stores it in the RAM 16 by the main CPU 15. . The device address is unique to each device, and is assigned to each slave device. For example, the device address is expressed by a 12-digit hexadecimal number.

  Next, the master device 10 performs a name search process for obtaining the device name of the slave device 20 in step S13.

  At this time, the master device 10 uses the device address of the slave device 20A that has responded in step S12 as a destination address, and uses a baseband packet including a name search command (Name Discovery) that commands a return of the device name of the slave device 20 Created by the processing unit 13. Then, the master device 10 operates the RF processing unit 12 and the antenna 11 to transmit a radio wave including a name search command as shown in FIG.

  On the other hand, when the slave device 20A inputs a name search command from the short-range wireless communication CPU 24, the device name in the EEPROM 27 is read by the short-range wireless communication CPU 24 and a response including the device name is returned to the master device 10. To do. Here, the device name stored in the EEPROM 27 is information stored by the main CPU 25 in advance by an operation input signal corresponding to the operation of the operation input unit 29 before performing device registration processing. The contents of device name input processing to the EEPROM 27 and device name output processing from the EEPROM 27 will be described later.

  When the master device 10 receives a response to the name search command from the slave device 20A, the baseband processing unit 13 extracts the device name of the slave device 20A from the packet data, and temporarily stores it in the RAM 16 by the main CPU 15. .

  Next, in step S14, the device name input by the user operation in step S11 (step S2) and the device name of the slave device to be registered in the master device 10 matches the device name acquired in step S13. If they match, the process proceeds to step S15. If they do not match, the process proceeds to step S17.

  In step S15, the short-range wireless communication CPU 14 detects that the slave device 20 that the user wants to establish communication with the master device 10 is detected in step S14. Therefore, the slave device having the matching device name is detected. Call processing (Page) for calling 20 is performed.

  At this time, as shown in FIG. 4C, the short-range wireless communication CPU 14 uses the device address corresponding to the device name determined to match in step S14 as the destination address, and uses the packet data including the calling instruction as the baseband. The radio wave including the calling instruction is transmitted to the slave device 20A by causing the processing unit 13 to create and operating the RF processing unit 12 and the antenna 11.

  On the other hand, when the slave device 20A receives a call command including its own device address, the slave device 20A returns a response to the call command to the master device 10, and the short-range wireless communication CPU 14 returns a response to the call command in step S16. By receiving, it is determined that the registration of the slave device 20A is completed. Thereby, the main CPU 15 ends the process of step S3 in FIG. 2, and as shown in FIG. 2C, a registration completion message 34 indicating that the registration of the slave device 20 with the device name “XXXX” is completed. Displayed on the display screen 18a and the process ends.

  On the other hand, if it is determined in step S14 that the device name input in step S11 (step S2) does not match the device name acquired in step S13, it is determined in step S17 that the device name does not match. It is determined whether or not the number of times exceeds the number of slave devices 20 whose device addresses and device names are detected in step S12 and step S13. If not, the processing from step S14 is repeated. Thus, when device addresses and device names for a plurality of devices are detected in step S12 and step S13, one of the device names is input in step S11 (step S2) by repeating the process in step S14. Judgment is made by repeating whether the device name matches.

  On the other hand, when it is determined in step S17 that the number of times determined not to match in step S14 exceeds the number of slave devices 20 detected in steps S12 and S13, in step S11 (step S2). In step S18, it is determined that the slave device 20 having the device name that the user desires cannot be registered. As a result, the main CPU 15 ends the process of step S3 in FIG. 2, and displays a registration impossible message 35 indicating that the slave device 20 having the device name “XXXX” cannot be registered, as shown in FIG. It displays on the screen 18a and complete | finishes a process.

  In a wireless communication system that performs such device registration processing, a device name that can be easily determined by the user is input to the slave device 20 and stored in the EEPROM 27 in advance, and when the slave device 20 is registered in the master device 10, The user can easily register the slave device 20 in the master device 10 by inputting the device name stored in the slave device 20 into the master device 10.

  The device name stored in the slave device 20 before the device registration processing is performed as described above, depending on the memory configuration of the EEPROM 27 of the slave device 20, as shown in FIG. 5, FIG. 6, or FIG. Processing is performed.

  As shown in FIG. 5, the memory configuration of the EEPROM 27 includes, for example, a memory address “0” set in the device address storage area 41 and a memory address “1” set in the device name storage area 42. When 42 can be arbitrarily rewritten by the user's operation, the device name in the device name storage area 42 is rewritten by the main CPU 25 according to the operation input signal from the operation input unit 29.

  When rewriting the device name storage area 42, the slave device 20 having the EEPROM 27 having such a memory configuration operates in a state where a device name input screen as shown in FIG. After the device name is input to the device name input field 32 by the operation of the input unit 29, the character input to the device name storage area 42 in the device name input field 32 by the main CPU 25 when the determination button 33 is selected. Rewrite to a column. As a result, the character string stored in the device name storage area 42 becomes the device name of the slave device 20 that is easily understood by the user.

  As a result, the device name is rewritten in the device name storage area 42 with a character string that the user can easily understand in the slave device 20, and the device name written in the device name storage area 42 is changed to the device name input field in FIG. 32, the process of FIG. 3 is performed. In step S13, in response to receiving the name search command, the slave device 20 returns the character string written in the device name storage area 42 as a device name, thereby writing the device name storage area 42. The slave device 20 can be registered in the master device 10 with the device name.

  In addition, as shown in FIG. 6, the memory configuration of the EEPROM 27 is such that the device address storage area 41 and the device name storage area 42 are set to be non-rewritable, and are separate from the device address storage area 41 and the device name storage area 42. In addition, an arbitrary name area 43 that can be rewritten by a user operation is provided. The arbitrary name area 43 stores not only the character string corresponding to the operation of the operation input unit 29 by the main CPU 25 but also, for example, a telephone number when the slave device 20 is a mobile phone. A character string “MY PHONE” or “MY PDA” indicating the model or the like of the device 20 may be stored.

  When rewriting the arbitrary name area 43, the slave device 20 provided with the EEPROM 27 having such a memory configuration displays the device name input screen as shown in FIG. After the device name is input to the device name input field 32 by the operation of 29, when the enter button 33 is selected, the main CPU 25 rewrites the arbitrary name area 43 with the character string input to the device name input field 32. . Thus, the character string stored in the arbitrary name area 43 becomes the device name of the slave device 20 that is easily understood by the user.

  The slave device 20 returns a device name stored in the device name storage area 42 or a character string stored in the arbitrary name area 43 as a response to the name search command from the master device 10. At this time, when an arbitrary name can be used as a device name by the master device 10, the slave device 20 uses the character string stored in the arbitrary name area 43 as a response to the name search command, and the master device 10 Is unusable as a device name, the character string stored in the device name storage area 42 is used as a response to the name search command. Thus, the slave device 20 functions as a switch 51 that changes the character string to be returned depending on whether or not an arbitrary character string can be used as a device name in the master device 10.

  Further, when the slave device 20 is a mobile phone, the memory configuration of the EEPROM 27 is such that, as shown in FIG. 7, in addition to the device address storage area 41 and the device name storage area 42, a telephone number storage area 44 and a mail (not shown) An address storage area and the like are provided. In the telephone number storage area 44, telephone numbers are stored in a state in which they cannot be rewritten at the initial setting of the mobile phone.

  The slave device 20 provided with the EEPROM 27 having such a memory configuration, as a response to the name search command from the master device 10, stores the device name stored in the device name storage area 42 and the telephone number stored in the telephone number storage area 44. Returns either a character string indicating e-mail or an e-mail address. At this time, when an arbitrary character string such as a telephone number can be used as the device name by the master apparatus 10, the slave device 20 stores the character string stored in the telephone number storage area 44 or the like different from the device name. Is a response to the name search command, and if an arbitrary character string cannot be used as the device name by the master device 10, the character string stored in the device name storage area 42 is set as a response to the name search command. Thus, the slave device 20 functions as a switch 51 that changes information to be returned depending on whether or not an arbitrary character string can be used as a device name in the master device 10.

[Effect of the first embodiment]
As described above in detail, according to the wireless communication system according to the first embodiment to which the present invention is applied, identification information (for example, device name) unique to the slave device 20 that is the control target device input according to the user's operation. And the identification information received from the slave device 20, the slave device 20 can be registered in the master device 10 as a slave device 20 that performs data communication thereafter. It is possible to simplify the user's operation when registering the slave device 20 at the same time.

  That is, the user himself / herself sets the device name of the slave device 20 that can be identified by the user to the slave device 20 and inputs the device name of the slave device 20 to be registered in the master device 10 in this state. Both the device name to be set to the device name and the device name that the master device 10 recognizes to be the slave device 20 can be used as a device name that can be easily understood by the user. Therefore, a plurality of slave devices 20 that are candidates for registration in the master device 10 are detected by the plurality of master devices 10, and, for example, compared to the case where the user selects the device names of the plurality of slave devices 20 in hexadecimal notation. The slave device 20 desired by the user can be easily registered in the master device 10.

  Further, according to this wireless communication system, the device name input field 32 or the like is displayed on the display unit 18 of the master device 10 so that the device name of the slave device 20 desired to be registered in the master device 10 is input. Since only the slave device 20 can be specified, even if a plurality of slave devices 20 are detected by the inquiry process or the name search process, only the desired slave device 20 is registered from the plurality of slave devices 20. be able to.

  Furthermore, according to the wireless communication system, the slave device 20 compares the device name, which is an arbitrary name according to the user's operation on the operation input unit 19, with the arbitrary device name received from the slave device 20. Therefore, by storing an arbitrary device name that can be easily understood by the user in the slave device 20 and inputting the arbitrary device name into the master device 10, the desired slave device 20 can be easily stored in the master device 10. You can register.

  Further, according to this wireless communication system, the device name expressed in hexadecimal or the like stored in advance in the EEPROM 27 of the slave device 20 is rewritten to a character string that can be easily understood by the user, and the slave device 20 is registered in the master device 10. Therefore, it is not necessary for the user to recognize a desired slave device 20 by judging a hexadecimal number or the like, and a slave device 20 different from the desired slave device 20 is erroneously registered in the master device 10. In addition, it is possible to prevent any slave device 20 from being registered due to a user input error.

Omitted.

  The wireless communication system according to the second embodiment is characterized in that the slave device 20 is registered in the master device 10 by encoding the device name to be set in the slave device 20 and reading it by the master device 10. In the device registration process of such a wireless communication system, the display of the master device 10 is changed as shown in FIG. 8, and the display of the slave device 20 is changed as shown in FIG. Is performed by the master device 10 and the slave device 20.

  In the device registration process of such a wireless communication system, first, as shown in FIG. 8A, when the user operates the operation input unit 19 of the master device 10, a device registration button is displayed on the display screen 18a of the display unit 18. A device registration screen including 31 is displayed. When the user operates the operation input unit 19 to detect an operation input signal indicating that the device registration button 31 is selected by the main CPU 15 (step S1), the main CPU 15 displays the display screen as shown in FIG. 8B. In 18a, an information reading message 61 that prompts the user to read information of the slave device 20 that the user desires to register in the master device 10 is displayed.

  The slave device 20 displays a list of various processes related to communication settings on the display screen 28a of the display unit 28 as shown in FIG. 9A when the operation input unit 29 is operated by the user.

  When the operation input unit 29 is operated and information display processing is selected from the list 71 (step S31), as shown in FIG. 9B, the device address and the device name are converted into a QR code and visible. A transition is made to an information display screen including the QR code 72 that has become a code. Here, the slave device 20 converts a preset device address and device name into a QR code, stores them in the EEPROM 27, reads the QR code 72 by the main CPU 15 when the information display screen is changed, and displays the display unit 28. To display. The device address and device name are not limited to the QR code 72, and may be displayed as a one-dimensional information barcode or a stacked barcode obtained by stacking one-dimensional information into a two-dimensional information. You may display with the other two-dimensional code proposed.

  In the state where the QR code 72 is displayed on the slave device 20 and the information reading message 61 is displayed on the master device 10 as described above, the QR code 72 is read by a QR code reader (not shown) of the master device 10 (see FIG. 8, step S21).

  Here, when the master device 10 cannot read the QR code 72, the main CPU 15, as shown in FIG. 8C, information such as “failed to read information of the device to be registered”. An information reading NG screen including the reading failure message 62 is displayed on the display screen 18a.

  On the other hand, when reading of the QR code 72 is completed by the master device 10, the main CPU 15 acquires the device address and device name of the slave device 20 by analyzing the information read by the QR code reader, and temporarily Therefore, it is stored in the RAM 16. Further, as shown in FIG. 8B, the main CPU 15 completes reading of the slave device 20 to be registered, and sends an information reading completion message 63 indicating the device address and device name as the read information to the master device 10. An information reading OK screen including a start button 64 for starting processing for registering the slave device 20 is displayed on the display screen 18a. In this state, when the operation input signal in which the operation input unit 19 is operated and the start button 64 is selected is detected by the main CPU 15 (step S22), the device registration process by the short-range wireless communication CPU 14 is started (step S3). .

  When the process proceeds to step S3 in FIG. 8, the short-range wireless communication CPU 14 determines in step S41 in FIG. 10 that the device name of the slave device 20 has been input by the user, and makes an inquiry in step S12. Processing is performed to acquire the device address of the slave device 20, and name search processing in step S13 is performed to acquire the device name of the slave device 20.

  Next, in step S42, the short-range wireless communication CPU 14 reads the device address read in step S41 (step S21), the device address of the slave device to be registered in the master device 10, and the device address acquired in step S12. Whether or not matches.

  If they match, the short-range wireless communication CPU 14 detects that the slave device 20 that the user wants to establish communication with the master device 10 is detected in step S42. Then, in step S16, as shown in FIG. 8E, a registration completion message 34 indicating that the registration of the slave device 20 with the device name “XXXXXX” is completed is displayed on the display screen 18a. Display and finish the process.

  On the other hand, if it is determined in step S42 that the device address input in step S41 (step S21) does not match the device address acquired in step S12, it is determined in step S17 that the device address does not match. It is determined whether or not the number of times exceeds the number of slave devices 20 whose device addresses and device names are detected in step S12 and step S13. If not, the processing from step S42 is repeated. Then, when it is determined that the number of times determined not to match in step S42 exceeds the number of slave devices 20 detected in steps S12 and S13, the device input in step S41 (step S21) In step S18, it is determined that the slave device 20 having the device name desired by the user cannot be registered. As a result, as shown in FIG. 8 (f), the main CPU 15 displays a registration impossible message 35 indicating that the slave device 20 having the device name “XXXX” cannot be registered on the display screen 18 a and ends the process.

  In a wireless communication system that performs such device registration processing, a device address and a device name are converted into QR codes in advance and stored in the EEPROM 27 of the slave device 20. When the slave device 20 is registered in the master device 10, the QR code is stored. The slave device 20 can be easily registered in the master device 10 simply by reading by the master device 10.
