  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of an infrared remote control system (referred to as an infrared remote control system) according to an embodiment of the present invention. In FIG. 1, an infrared remote control system according to an embodiment of the present invention is connected to a personal computer (hereinafter referred to as a personal computer) 1, 3-1 to 3-5 and a personal computer 1 with a cable and has an infrared remote control function ( Hereinafter, the cellular phone terminal 2 having an infrared remote control function (not shown) and infrared receivers 4-1 to 4-5 that can be connected to each of the plurality of personal computers 3-1 to 3-5 by cables. It consists of and.

  Usually, when it is desired to transmit certain information in the personal computer 1 to a plurality of personal computers 3-1 to 3-5 at the same time, it is transmitted from the personal computer 1 to the personal computers 3-1 to 3-5 by wire or wireless.

  In the embodiment of the present invention, the transmission data 100 transmitted from the personal computer 1 to the personal computers 3-1 to 3-5 can be transferred between the personal computer 1 and the mobile phone terminal 2 such as a cable or infrared communication. To the mobile phone terminal 2 by the method. At this time, the mobile phone terminal 2 sets the infrared remote control function of the mobile phone terminal 2 so that the transmission data 100 can be immediately emitted to the light receivers 4-1 to 4-5 and transmitted.

  The transmission data 100 transferred to the mobile phone terminal 2 is temporarily stored in its internal memory (not shown), and a header part, a set identification code, and a stop part are added to the transmission data 100, and the transmission data 110 is transmitted from the infrared remote control function. As shown in FIG.

  When receiving the transmission data 110 emitted from the cellular phone terminal 2, the light receivers 4-1 to 4-5 temporarily store the transmission data 110 in an internal memory (not shown) and perform code comparison / determination. This determination result is notified to the outside by a notification means such as an LED (Light Emitting Diode).

  For example, when the transmission data 110 can be received correctly, the LED is changed from red to blue. When the transmission data 110 cannot be received correctly, the LED is changed from red to green. The user can be informed whether or not the reception has been correctly performed by color.

  The receivers 4-1 to 4-5 remove the header, identification code, and stop added by the mobile phone terminal 2 from the transmission data 110 determined to have received light correctly, and return to the transmission data 100 to return to a plurality of personal computers 3. -1 to 3-5.

  When the plurality of personal computers 3-1 to 3-5 receive the data transferred from the light receivers 3-1 to 3-5, they receive the transmission data 100 transmitted from the personal computer 1 by the conventional wired or wireless method. Therefore, the information of the transmission data 100 can be acquired by infrared communication as in the normal process.

  As described above, when transmitting the transmission data 100 from the personal computer 1 to the plurality of personal computers 3-1 to 3-5 at the same time, first, as a preliminary preparation, the user uses the mobile phone terminal 2 to receive the receivers 4-1 to 4-1. It is necessary to obtain the same identification code set to 4-5. Since the mobile phone terminal 2 is used to obtain this identification code, it can be easily obtained by downloading the identification codes of the light receivers 4-1 to 4-5 from a dedicated site.

  Next, it is necessary to enable data transmission from the personal computer 1 to the mobile phone terminal 2. This is because if the mobile phone terminal 2 has a plurality of personal computers 3-1 to 3-35, This can be achieved by causing the telephone terminal 2 to make a pseudo-recognition like a transmission destination and transmitting data from the personal computer 1 to the mobile phone terminal 2.

  Therefore, the personal computer 1 transmits the transmission data 100 that is normally transmitted to the plurality of personal computers 3-1 to 3-5, except that the mobile phone terminal 2 is pseudo-recognized as a counterpart. Normal operation is performed.

  As described above, in the embodiment of the present invention, data is transmitted to a plurality of target devices at a time by using a mobile phone terminal as a light emitting side of a wireless device and performing wireless communication with a light receiver. It can be performed.

  In the embodiment of the present invention, by using the above method, the mobile phone terminals of various manufacturers can be used for the above infrared communication without unifying the format of the infrared communication set for each mobile phone. Can be used.

  Furthermore, in the embodiment of the present invention, the above-described method is used, a comparison function is mounted on the light receiver, and the comparison result is notified to the outside by a notification means such as an LED, so that more reliable infrared remote control transmission is possible. The user can be notified by the change in the color of the LED whether or not the light can be received normally.

  Next, an embodiment of the present invention will be described. Since the infrared remote control system according to one embodiment of the present invention has the same configuration as the infrared remote control system according to the embodiment of the present invention shown in FIG. 1, the description of the configuration is omitted.

  FIG. 2 is a block diagram showing the configuration of a mobile phone terminal according to an embodiment of the present invention. In FIG. 2, the mobile phone terminal 2 includes a memory unit 21, a conversion unit 22, and a light emitting unit 23. In addition, since the original function of the mobile phone 2 is not directly related to the present invention, description of its configuration and operation is omitted.

  FIG. 3 is a block diagram showing a configuration of a light receiver according to an embodiment of the present invention. In FIG. 3, the light receiver 4 includes a light receiving unit 41, a memory unit 42, a comparison unit 43, an LED unit 44, a conversion unit 45, and a transmission unit 46. The light receivers 4-1 to 4-5 shown in FIG. 1 have the same configuration as the light receiver 4.

  4 and 5 are transition diagrams of the setting screen on the display (not shown) of the mobile phone terminal 2 of FIG. 2, and FIG. 6 is a flowchart showing the operation of the light receiver 4 of FIG. FIG. 4 is a waveform diagram showing a configuration of transmission data 110 in FIGS. 2 and 3. An infrared remote control system according to an embodiment of the present invention will be described with reference to FIGS.

  First, the overall operation will be described. When information on the personal computer 1 is transmitted to a plurality of personal computers 3-1 to 3-5 in the same manner, it is usually transmitted from the personal computer 1 to the personal computers 3-1 to 3-5 by wire. The transmission data 100 to be transmitted can be simulated and transmitted to the mobile phone terminal 2. In this case, for example, a communication method that can be transferred between the personal computer 1 and the mobile phone terminal 2 using a cable or infrared communication is used, and the transmission data 100 is transmitted to the mobile phone terminal 2 by this transferable communication method. To do.

  At this time, as shown in FIGS. 4 and 5, the mobile phone terminal 2 is portable so that the transmission data 100 from the personal computer 1 can be immediately emitted and transmitted to the light receivers 4-1 to 4-5. The telephone terminal 2 is set up beforehand.

  The transmission data 100 transferred to the mobile phone terminal 2 is temporarily stored in the memory unit 21, and the header unit, the set identification code, and the stop unit are added to the transmission data 100 using the conversion unit 22. 7 is rearranged in the order of the identification code, the transmission data 100, and the stop unit to obtain the transmission data 110 shown in FIG. 7, and the transmission data 110 is sent to the light emitting unit 23 from the light emitting unit 23 to the light receivers 4-1 to 4-4. Sends light to -5.

  When the light receivers 4-1 to 4-5 receive the transmission data 110 emitted from the mobile phone terminal 2 by the light receiving unit 41, the light receiving units 41 temporarily store the transmission data 110 in the memory unit 42, and the comparison unit 43 compares the codes. Make a decision.

  Further, the determination result in the comparison unit 43 is notified to the user using the LED unit 44. For example, the LED unit 44 can receive the transmission data 110 correctly by changing from red to blue when the transmission data 110 is correctly received, and changing from red to green when the transmission data 110 cannot be received correctly. Tell the user whether or not

  The transmission data 110 determined to have been correctly received by the comparison unit 43 is sent to the conversion unit 42. The conversion unit 42 converts the header portion, the identification code, the transmission data 100, and the transmission data 110 configured by the stop portion from the header portion, The identification code and the stop part are deleted and converted to transmission data 100 only, and transferred from the transmission part 46 to a plurality of personal computers 3-1 to 3-5.

  When the plurality of personal computers 3-1 to 3-5 receive the data transferred from the light receivers 4-1 to 4-5, the transmission data 100 transmitted from the personal computer 1 by the conventional cable is converted into the light receiver 4-4. Since it is received through 1-4-5, information of the transmission data 100 can be acquired by a normal process.

  When performing the above operation, first, as a preliminary preparation, the mobile phone terminal 2 needs to obtain the same identification codes of the receivers 4-1 to 4-5. To obtain the identification codes of the receivers 4-1 to 4-5, since the mobile phone terminal 2 is used, the identification codes of the light receivers 4-1 to 4-5 are easily obtained from a dedicated site. be able to.

  Next, it is necessary to enable data transmission from the personal computer 1 to the mobile phone terminal 2. However, as in this example, if the transmission destination is a plurality of personal computers 3-1 to 3-5, the mobile phone terminal 2 is connected to the personal computer 1 (the plurality of personal computers 3-1 to 3-5). ) And make a transmission from the personal computer 1 to the mobile phone terminal 2.

  Therefore, since the personal computer 1 itself perceives that the mobile phone terminal 2 is a transmission destination in a pseudo manner, except for transmitting data to the mobile phone terminal 2, transmission that is normally transmitted to a plurality of personal computers 3-1 to 3-5. The normal operation of transmitting data 100 is performed.

  The cellular phone terminal 2 first temporarily stores the transmission data 100 received from the personal computer 1 in the memory unit 21. In order to select the identification code, the cellular phone terminal 2 selects the identification codes of the light receivers 4-1 to 4-5 before being transmitted from the personal computer 1 or after being transmitted, as shown in FIGS. 4 and 5. Then, a setting screen for emitting light to the light receivers 4-1 to 4-5 is displayed on a display (not shown), and the user performs the setting.

  FIG. 4 is a transition diagram of the setting screen on the display of the mobile phone terminal 2. First, the user sets the mode of the remote control (A1 in FIG. 4), and is the normal remote control mode (a: normal remote control)? The information transfer mode (b: information transfer) is selected. Here, in this embodiment, the information transfer mode is selected.

  Next, the user selects a transmission method (A2 in FIG. 4). Here, there is one transmission (a: one transmission) and program transmission (b: program transmission). It is used when transmitting the information transmitted to the terminal 2 as it is once. The program transmission can be transmitted several times by adding different information to the same information by the program and transmitting the information transmitted to the mobile phone terminal 2 several times. This is used when information transmitted to the mobile phone terminal 2 is continuously transmitted.

  When the one-time transmission is selected, the user selects the identification codes (a: A-1, b: A-2,...) Of the light receiving units 4-1 to 4-5 (A3 in FIG. 4). Here, when the identification code of the light receivers 4-1 to 4-5 to be received is selected, for example, a: A-1 is selected, the screen transits to the screen waiting for the transfer state (A5 in FIG. 4).

  If program transmission is selected, the user transitions to a program editing screen (A4 in FIG. 4 and B1 in FIG. 5). In this program editing screen, first, the user wants to edit the program number (a: transfer information first time, identification code A-1, b: transfer information second time, identification code A-1, c: transfer information third time, identification code. Place the cursor on (A-2,...) And press Edit.

  Next, the user sets which identification code (a: A-1, b: A-2,...) Is added to the information transmitted to the mobile phone terminal 2 (B2 in FIG. 5). I do. As a result, a transition is made to the program edit screen (B3 in FIG. 5) on the display of the mobile phone terminal 2.

  When the user selects all programs to be used and completes the program setting, the program editing is completed. When the user program setting is completed on the display of the mobile phone terminal 2, the screen shifts to a screen waiting for transfer information (A5 in FIG. 4).

  When the above setting is performed on the display and the identification code is selected, the mobile phone terminal 2 sends the transmission data 100 temporarily stored in the memory unit 21 to the conversion unit 22, and the selected identification code and header unit are selected. The stop part is added to the transmission data 100, and rearranged, for example, like a header part, an identification code, transmission data 100, and a stop part, and sent to the light emitting part 23 as the transmission data 110, so that the light emitting part 23 emits light.

  In the light receivers 4-1 to 4-5, first, the transmission data 110 received from the header part to the stop part by the light receiving part 41 is temporarily stored in the memory part 42 (step S <b> 1 in FIG. 6), and the transmission data 110 is compared with the comparison part 43. (Step S2 in FIG. 6). The comparison unit 43 performs two types of determination (determination 1 and determination 2) as to whether the signal code of the transmission data 110 is correct (steps S3 and S5 in FIG. 6). In this case, since the transmission data 110 is composed of four parts, that is, the header part, the identification code, the transmission data 100, and the stop part, the comparison unit 43 makes a determination using these parts.

  The determination of the comparison unit 43 is positive only when the two determination conditions of the determination 1 and the determination 2 become positive when the transmission data 110 received by the light receivers 4-1 to 4-5 is input.

  The determination condition of determination 1 is whether or not the section length of each code of the transmission data 110 is as set. As the determination part, as shown in FIG. 7, the transmission data 100 is data transmitted to a plurality of personal computers 3-1 to 3-5 and cannot be set. The lengths of the Lo section, the Hi section and Lo section of the identification code, the Hi section of the stop section, and the section from the transmission data 100 to the stop section (Lo section of the transmission data 100) are the mobile phone terminal 2 and the light receiver 4-1. Since it is a code only between ˜4-5, it can be set arbitrarily.

  Therefore, the comparison unit 43 performs determination based on the lengths of the Hi section and Lo section of the header section, the Hi section and Lo section of the identification code, the Lo section of the transmission data 100, and the Hi section of the stop section. The comparison unit 43 compares the section lengths of the transmitted transmission data 110 and the set portion, and determines that the value is positive if it is within an arbitrary error rate, and determines that it is incorrect if it is out of the range.

  If the comparison unit 43 makes a positive determination, the process proceeds to the determination condition of determination 2. If the comparison unit 43 determines that it is incorrect, the comparison unit 43 transmits an error signal to the LED unit 44, turns on an incorrect LED color, for example, a green LED, and informs the user that it cannot be normally received.

  The determination condition of determination 2 is whether or not the order of each part of the transmission data 110 is correct. The comparison unit 43 compares and determines whether the order of the header part, the identification code part, the transmission data 100, and the stop part is correct, and determines that the arrangement of the header part, the identification code part, the transmission data 100, and the stop part is positive. If the value is lowered, a positive signal is transmitted to the LED unit 44, and a positive LED color, for example, a blue LED is lit to inform the user that the signal can be normally received.

  That is, the comparison unit 43 lights the LED unit 44 in green if the determinations 1 and 2 are wrong (steps S4 and S6 in FIG. 6), and if the determinations 1 and 2 are positive, the LED unit 44 is blue. Is turned on (step S7 in FIG. 6).

  When the comparison unit 43 receives the correct transmission data 110, the comparison unit 43 transmits the transmission data 110 to the conversion unit 45, and the conversion unit 45 deletes the identification code, the header part, and the stop unit from the transmission data 110 to make only the transmission data 100. The data is converted and sent to the transmitter 46 (step S8 in FIG. 6). The transmission unit 46 transmits the transmission data 100 to the plurality of personal computers 3-1 to 3-5. The above operation is a series of flows of the light receivers 4-1 to 4-5.

  On the other hand, when the transmission data 110 from the mobile phone 2 is not even received, the LED unit 44 remains in the normal lighting color, for example, red, and the user cannot receive the transmission data 110. To inform. In this embodiment, infrared remote control transmission can be made more reliable by using this function.

  The transmission data 110 transmitted to the conversion unit 45 is converted into only the transmission data 100 by removing the header portion, the identification code portion, and the stop portion by the conversion unit 45, and the converted transmission data 100 is sent to the transmission unit 46. The transmission unit 46 transmits to the connection cables of the plurality of personal computers 3-1 to 3-5. When the plurality of personal computers 3-1 to 3-5 receives the transmission data 100, the conventional personal data is only received from the light receivers 4-1 to 4-5. Get information.

  As described above, in this embodiment, the mobile phone terminal 2 is used as the light emitting side of the wireless device, and wireless communication is performed by the light receivers 4-1 to 4-5, thereby a plurality of receivers 4-1 to 4-1 are performed at a time. Transmission is possible for 4-5.

  Further, in this embodiment, by using the above-described method, it becomes possible to use the cellular phone terminals of various manufacturers without unifying the format as in infrared communication.

  Further, in this embodiment, the receivers 4-1 to 4-5 are provided with a comparison function (comparison unit 43), and the determination result is displayed using the LED unit 44, thereby enabling more reliable infrared remote control transmission. Thus, it is possible to notify the user whether or not the light has been normally received by the color of the LED unit 44.

  Next, another embodiment of the present invention will be described. An infrared remote control system according to another embodiment of the present invention has the same configuration as that of the infrared remote control system according to the embodiment of the present invention shown in FIG. The devices 4-1 to 4-5 have the same configuration as the mobile phone 2 and the light receivers 4-1 to 4-5 according to the embodiment of the present invention shown in FIGS.

  In the above description of one embodiment of the present invention, the information on the personal computer 1 is transmitted to all of the plurality of personal computers 3-1 to 3-5, but does not compete with other devices such as a TV (TV). The identification code is provided as described above. By making this identification code also settable on the side of the light receivers 4-1 to 4-5, for example, among the personal computers 3-1 to 3-5, the personal computers 3-1, 3 are provided. -2, 3-3, 3-5 can be transmitted, and transmission to the personal computer 4-4 can be disabled.

  This principle is that light emission is not accepted unless the identification code matches the receiver side. As an additional operation, when it is desired to receive the identification code set in the cellular phone terminal 2, the cellular phone terminal 2 When the same identification code as the identification code set in step 1 is set and it is not desired to receive light, it is only necessary to set the identification code different from the identification code set in the mobile phone terminal 2.

  Therefore, by utilizing the fact that the mobile phone terminal 2 is always carried by the user and the fact that the mobile phone terminal 2 has an infrared remote control function, a mobile phone terminal with an infrared remote control function function that exists in the prior art is used. Wireless transmission to the transmitter of the wireless device and between the receivers 4-1 to 4-5 conforming to the function enables transmission to a plurality of devices at once, which was impossible with infrared communication. Become.

  In the present invention, the case where data transmission from one personal computer to a plurality of personal computers is described at the same time, but the mobile phone with audio function transmits the music data being played back by remote control so that the earphone with the receiver is attached. In addition, the present invention can be applied to a case where a plurality of persons who can receive light simultaneously listen to a song reproduced by a mobile phone with audio.
