Japanese Patent Laid-Open No. 2002-238083

  However, when the selection of the identification code is entrusted to the user, there is a possibility that the game cannot be performed due to the mismatch of the identification code unless the user selects the correct identification code. A user who wants to participate in a game that has already been played needs to select an unused identification code after confirming the identification code that has already been used. There is also a risk of bothering the user.

  Accordingly, an object of the present invention is to provide a remote control toy system or the like that can set an appropriate identification code for both the wireless device and the driving device without requiring the user to perform a special operation for selecting the identification code. To do.

  The present invention solves the above-described problems by the following means. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  A remotely operated toy system (1) according to the present invention includes a wireless device (2) that transmits control information corresponding to a user's operation, and a drive device (3) that is controlled based on control information transmitted from the wireless device. The wireless device includes a transmission means (18) for transmitting the control information by including an identification code set as its own identification code among a plurality of predetermined identification codes, and the control information. Detection means (19, 11) for receiving and detecting an identification code included in the received control information, and one unused identification code among the plurality of identification codes based on a detection result by the detection means And a code selection means (11) for setting as a self-identification code, the drive device receiving means (30) for receiving the control information and the control received by the reception means. An identification means (21) for identifying an identification code included in the information, an identification code already used at the reception start time of the reception means, and an identification code detected earliest among other identification codes And the code setting means (21) for setting as a self-identification code, the above-mentioned problems are solved.

  According to the present invention, the radio receives the control information that has already been transmitted, detects the identification code included in the control information, thereby detecting the identification code that is already used, and based on the detection result Thus, one unused identification code can be selected, and the selected identification code can be automatically set as its own identification code. “Select based on detection result” means that the detected identification code is selected by removing it from a plurality of predetermined codes as an identification code in use, or a predetermined unusable identification code is considered. The selection includes taking into consideration conditions other than the identification code detected by the detection means, such as determination of an identification code that can be selected based on the detected identification code.

  On the other hand, in the driving device, if the identification code set in the radio to be associated with the driving device is detected earliest after the detection of the identification code being used, the detected identification code is the own of the driving device. It is automatically set as an identification code. Therefore, if the identification information included in the control information is transmitted from the wireless device to be associated with the driving device so as to be detected earliest as an unused identification code, the wireless device and the driving device to be associated with the wireless device are 1 An identification code to be associated with the pair 1 can be automatically set.

  A remote control toy that determines whether it is control information for itself or not based on the identification information received by the drive device by transmitting control information including its own identification code and operation control information to the drive device from the wireless device In the system, the means already provided in the remote control toy system can be used for the transmission means of the radio and the reception means and identification means of the driving device in the present invention. In addition, for example, in a remote-controlled toy system that receives control information from another wireless device and determines its own transmission time, the detecting device of the wireless device may use an identification code detecting device in its function. it can.

  The code setting means of the driving device detects an identification code identified within a certain time from the reception start time by the identifying means as the identification code already used, and after the lapse of the certain time, The identification code detected earliest except for the stored identification code may be set as its own identification code. Thereby, the identification code detected within a predetermined time from the reception start time of the driving device is stored as an identification code in use. Therefore, the control signal from the wireless device to be associated with the driving device may be transmitted after the predetermined time has elapsed.

  The code selection means of the radio unit uses the identification code as one of the plurality of identification codes excluding the identification code detected at a fixed time after the detection means starts receiving the control information. You may select it as a code. Thereby, an identification code obtained by removing the identification code detected by the detecting means from a plurality of predetermined identification codes can be used as an unused identification code, and one of the unused identification codes may be selected. .

  The drive device (3) in the present invention is a drive device controlled based on control information corresponding to a user operation transmitted from the wireless device (2), and receiving means (30) for receiving the control information. And an identification means (21) for identifying an identification code included in the control information received by the reception means; an identification code already used at the reception start time in the reception means; Code setting means (21) for setting the identification code detected earliest among the codes as its own identification code; This drive device can function as the drive device of the remote-controlled toy system according to claim 1.

  The remote-control toy system (1) identification code setting method according to the present invention is controlled based on the radio (2) that transmits control information corresponding to the user's operation and the control information transmitted from the radio. An identification code setting method in a remote-controlled toy system including a drive device (3), wherein the wireless device uses an identification code set as its own identification code among a plurality of predetermined identification codes. The control information is transmitted and received, the control information is received, the identification code included in the received control information is detected, and the unused one of the plurality of identification codes is detected based on the detection result by the detection means. One identification code is selected and set as its own identification code, and the drive device receives the control information, and the identification code included in the control information received by the receiving means. By detecting the identification code already used at the reception start time in the receiving means, and setting the identification code detected earliest among other identification codes as its own identification code. Solve the problem. As a result, as described above, an unused identification code can be automatically set in the wireless device and the driving device in the remote-controlled toy system.

  As described above, according to the present invention, in the wireless device, one unused identification code is selected from a plurality of predetermined identification codes based on the received identification code, and is set as its own identification code. In the driving device, the identification code that has already been used at the start of reception is detected, and the identification code detected first among the other identification codes is set as its own identification code. Therefore, it is possible to provide a remote control toy system or the like that can set an appropriate identification code for both the wireless device and the driving device without requiring a user to perform a special operation for selection.

  FIG. 1 shows an example of a form of a remotely operated toy system 1 according to the present invention. The remote control toy system 1 in this embodiment is composed of a set of a wireless device 2 and an automobile model 3 as a driving device. The wireless device 2 is provided with a throttle lever 4 and a steering lever 5 for the user to operate the automobile model 3. The configurations of the wireless device 2 and the automobile model 3 will be described later.

  FIG. 2 is a block diagram showing the configuration of the control system of the radio device 2. The wireless device 2 includes a macro computer 11 that functions as detection means and code selection means. The microcomputer 11 executes various calculations and operation control necessary for remote operation of the automobile model 3 in accordance with programs and data recorded in the built-in ROM 12 and RAM 13. The microcomputer 11 receives information corresponding to the operation states of the throttle lever 4 and the steering lever 5 described above.

  The power switch 14 is disposed between the power battery 15 and the power circuit 16. When the power switch 14 is turned on, power is supplied from the power supply battery 15 to the power supply circuit 16, and power necessary for the operation is supplied from the power supply circuit 16 to the microcomputer 11. As the power is turned on, the microcomputer 11 determines its own ID number and stores it in the RAM 13. This ID number and its setting method will be described later. An LED indicator 17 for confirming ID setting at the time of ID setting is also connected to the microcomputer 11.

  The microcomputer 11 is further connected to a transmission unit 18 and a reception unit 19. The microcomputer 11 generates digital data for instructing the operation of the automobile model 3 in accordance with the operation state of the operation member such as the throttle lever 4, and delivers the generated digital data to the transmission unit 18. The transmitter 18 converts the given data into an analog signal, and outputs control information in which the analog signal is superimposed on a predetermined carrier wave. In this embodiment, infrared light is used as a carrier wave. The receiving unit 19 receives control information transmitted from the wireless device, converts an analog signal obtained by removing a carrier wave component from the control information into digital data, and delivers the digital data to the microcomputer 11.

  The configuration of the control system of the automobile model 3 is shown in FIG. As shown in FIG. 3, the automobile model 3 also includes a microcomputer 21. The microcomputer 21 executes various calculations and controls necessary for operating the automobile model 3 in accordance with the control information sent from the wireless device 2 according to the programs and data recorded in the built-in ROM 22 and RAM 23. . The microcomputer 21 particularly functions as identification means and code setting means.

  The microcomputer 21 is connected to a left traveling motor 25L and a right traveling motor 25R through a motor driver 24 for independently traveling a pair of left and right wheels of the automobile model 3 respectively. The microcomputer 21 is connected to an LED indicator 26 for confirming the ID setting. Further, the automobile model 3 is provided with a power battery 27 and a power switch 28 for supplying power to the microcomputer 21 and the motors 25L and 25R.

  When the power switch 28 is turned on, power is supplied from the power supply battery 27 to the power supply circuit 29, and power necessary for the operation is supplied from the power supply circuit 29 to the microcomputer 21. When the power is turned on, the microcomputer 21 determines its own ID number and stores it in the RAM 23. The ID number setting method will be described later. Further, a receiving unit 30 is connected to the microcomputer 21. The receiving unit 30 receives the control information transmitted from the wireless device 2, converts an analog signal obtained by removing a carrier wave component from the received control information into digital data, and delivers the digital data to the microcomputer 21. In this embodiment, the power supply circuit 29 is configured independently of the motor driver 24, but may be built in the motor driver 24.

  The remote control toy system 1 according to this embodiment can be played even if there are a plurality of sets of remote control toy systems 1... 1 by setting different ID numbers to the plurality of remote control toy systems 1. It is configured. Hereinafter, the ID number in this embodiment will be described. In this embodiment, four types of ID numbers 1 to 4 are prepared as predetermined identification codes. In the plurality of remotely created toy systems 1... 1, any one of ID numbers 1 to 4 is set so as not to overlap each other. Therefore, a game in which a maximum of four remote control toy systems 1... 1 exist is possible.

  FIG. 4 shows a state in which two sets of remote control toy systems 1 and 1 exist, 1 is set for one ID number and 2 is set for the other ID number. The car model 3 is remotely operated only by the control information including the same ID number. Accordingly, the wireless operation machine 2 and the automobile model 3 having the same ID number are associated with each other to constitute the remote control toy system 1. In order to prevent crosstalk, the control information transmitted from the wireless device 2 is also received by the other wireless device 2, and the wireless device 2 refers to the ID number of the control information transmitted from the other wireless device 2 itself. The transmission timing of the control information is determined. The control signal transmitted from each wireless device 2 is also received by the car model 3 that is not associated with the ID number.

  FIG. 5 shows the transmission timing of control information from the wireless device 2 and its configuration. The transmission times of the wireless devices 2 set with different ID numbers have a time length of T1, and the transmission times are arranged in a fixed order (here, the reverse order of the ID numbers) so as not to overlap each other. ing. When four sets of time lengths T1 are secured, transmission from each wireless device 2 and the car model 3 is repeated in a cycle T2 (time length four times T1). By adjusting the transmission time between the wireless devices 2, the wireless device 2 with ID = 1 transmits the data with ID = 1, and the wireless device 2 with ID = 2 transmits the data with ID = 2. Control information is transmitted at the transmission time Y to be transmitted. In the remote control toy system 4 of this embodiment, four sets of time lengths T1 are secured because four types of ID numbers are prepared.

  Further, as shown in FIG. 5, the control information (hereinafter referred to as one block of transmission data) output from the wireless device 2 in one transmission period includes an ID number and operation control information. Yes. The ID number is 2-bit data indicating the ID number stored in the RAM 13 of the wireless device 2. The operation control information is information for instructing various operations on the automobile model 3, and includes, for example, motor drive information. The motor drive information report is data indicating the drive speed of each motor 25L, 25R calculated by the microcomputer 11 of the wireless device 2 based on the operation state of the throttle lever 4 and the steering lever 5.

  When the microcomputer 21 of the car model 3 receives the transmission data from the wireless device 2, it determines whether the ID number included in the transmission data matches the ID number stored in its own RAM 23. If not, it is determined that the operation control based on the transmission data is unnecessary, and the transmission data is ignored. When the transmission data having the same ID number is received, the operation of the motors 25L and 25R is controlled in accordance with the motor drive information included in the transmission data.

  Next, as shown in FIG. 4, when the third set of remotely operated toy systems 1 participates in the state where two sets of remotely operated toy systems 1 and 1 exist, the third set of remotely operated toy systems 1 The process for ID number setting performed in FIG. When the vehicle model 3 and the wireless device 2 are powered on, the ID number setting process is started independently for the wireless device 2 and the vehicle model 3, and their own ID numbers are automatically set. First, ID number setting processing performed in the wireless device 2 will be described.

  When the power switch 14 of the wireless device 2 is turned on and the microcomputer 11 is turned on, the microcomputer 11 starts receiving control information in the receiving unit 19 following a predetermined initialization process. The ID number setting process routine shown is executed. This ID number setting process is executed only once after the power is turned on. First, the microcomputer 11 sets a time-over timer (step S1). In order to be able to detect all the transmission data of ID numbers 1 to 4, the set time of the timer is set to the period T2 or more. Next, the LED indicator 17 is blinked (step S2). Thus, the user can recognize that the ID number setting process has started. Next, it is determined whether or not data from another wireless device 2 has been received (step S3). If it is determined that the data has been received, the process proceeds to step S4 to detect the ID number included in the received transmission data ( In step S4), the detected ID number is stored in the RAM 13 as an ID number in use (step S5).

  Thereafter, the process proceeds to step S6, where it is determined whether or not the time-over timer has ended. If not completed, the process returns to step S3. If a negative determination is made in step S3, steps S4 and S5 are skipped. In this embodiment, ID numbers 1 and 2 are detected in step S4, and ID numbers 1 and 2 are stored in the RAM 13 as ID numbers in use in step S5.

  If it is determined in step S6 that the time-over timer has ended, the ID number stored in the RAM 13 is excluded from all predetermined ID numbers, and whether or not there are remaining unused ID numbers. Is determined (step S7). When it is determined that there is no unused ID number, that is, when there are already four wireless devices 2 and all ID numbers 1 to 4 are used, the blinking speed of the LED indicator 17 is changed. (Step S8), the ID number setting process is terminated without transmitting anything. Since the blinking speed of the LED indicator 17 changes, the user can know that there is no unused ID and the ID number cannot be set. Note that, by turning on the power again, the wireless device 2 can execute the ID number setting process again.

  On the other hand, if it is determined in step S7 that there is an unused ID number, one ID number used by the wireless device 2 is selected from the unused ID numbers, and the selected ID number is set as its own ID number. It memorize | stores in RAM13 (step S9). The ID numbers are selected in the order of 1, 3, 2, and 4. For example, if there is only one unused ID number, that number is selected. When only ID number 1 is used, ID number 3 is selected, and ID numbers 1 and 4 are used. In this case, 3 is selected. In this embodiment, ID numbers 1 and 2 are used, so 3 is selected. Therefore, the ID number 3 is set to the wireless device 2 in the third set of remotely operated toy system 1 in step S9.

  After the ID number is set, the power-on operation is subsequently started. In this power-on operation, a predetermined initial setting operation such as determination of its own transmission time is executed. Thereafter, a normal operation control routine for transmitting transmission data including operation control information accompanying various user operations at its own transmission timing is entered. Thereby, the user can participate in the game.

  A normal operation control routine performed in the wireless device 2 is shown in FIG. The microcomputer 11 first determines whether or not transmission data from another wireless device 2 has been received (step S21). If it is determined that the transmission data has been received, the ID number included in the transmission data is its own ID number ( In this embodiment, 3), that is, it is determined whether or not it matches the ID number stored in the RAM 13 (step S22). If it is determined that they match, the process returns to the power-on operation. If it is determined that the ID number of the received data is different from the own ID number, the own transmission time is set in the transmission timer according to the ID number of the received data (step S23). If a negative determination is made in step S21, steps S22 and S23 are skipped.

  In step S24, it is determined whether or not the transmission timer has expired. If not, the process returns to step S21. If it is determined in step S24 that the process is terminated, the process proceeds to step S25, and transmission of one block of transmission data is started. At this time, data is also received in parallel. The transmission timer is a timer that times the transmission timing, and the time measurement ends for each time length T2 described above.

  In the subsequent step S26, it is determined whether or not the data transmission is completed. If the transmission is completed, the data started in the previous step S25 is compared with the data received in parallel with the transmission (step S26). S27). If it is determined that they do not match, it is determined that interference has occurred and the process returns to the power-on operation. If it is determined that they match, it is determined that there is no interference, and the next transmission timing (after time length T2) is set in the transmission timer (step S28). Then, it returns to step S21.

  Next, the ID number setting process performed in the automobile model 3 will be described. When the power switch 28 of the car model 3 is turned on and the microcomputer 21 is turned on, the microcomputer 21 starts receiving transmission data in the receiving unit 30 and executes the ID number setting processing routine shown in FIG. Execute. This ID number setting process is performed only once after the power is turned on. First, the microcomputer 21 sets a timer for time over (step S31). As with the time-over timer in the wireless device 2, the set time of the timer is set to be equal to or greater than the period T2 in order to be able to detect all transmission data with ID numbers 1 to 4.

Next, the LED indicator 26 is blinked (step S32). Thus, the user can recognize that the ID number setting process has been started in the driving device. It is determined whether or not data from another wireless device 2 has been received (step S33). If it is determined that data has been received, the process proceeds to step S34 to detect the ID number included in the transmission data (step S34). The obtained ID number is stored in the RAM 23 as an ID number in use (step S35). In this embodiment, ID numbers 1 and 2 are detected and stored in the RAM 23.

  Thereafter, the process proceeds to step S36, where it is determined whether or not the time-over timer has ended. If it is determined that the process has not ended, the process returns to step S33. If a negative determination is made in step S33, steps S34 and S35 are skipped.

  If it is determined in step S36 that the time-over timer has ended, it is determined whether an unused ID number has been received (step S37). That is, it is determined whether or not transmission data including an ID number other than the ID number stored in the RAM 23 as the ID number being used in step S35 is received among the received transmission data. In this step S37, it will be in a standby state until an unused ID number is received. If it is determined that an unused ID number has been received, the received unused ID number is stored in the RAM 23 as its own ID number, and the LED indicator 26 is turned on (step S38).

  Accordingly, in the car model 3 of the third set of remotely operated toy system 1, if the transmission data transmitted from the wireless device 2 of the third set of remotely operated toy system 1 is received in the standby state in step S37, the ID number 3 is stored as its own ID number. The user knows that the ID number has been set for the automobile model 3 by switching the blinking of the LED indicator 26 to lighting. After setting the ID number, the process proceeds to the normal operation of the car model 3. Note that the automobile model 3 does not operate until an unused ID number is received in step S37. In this case, the power may be turned on again to set the ID number again.

  In the car model 3, after the power is turned on, a timer for time over is set, and the ID number included in the transmission data received until the set time ends is stored in the RAM 23 as the ID number of the other wireless device. Remember. Therefore, the time count of the timer for time over in the car model 3 has been completed until the ID number is set in the wireless device 2 to be associated with the car model 3 and the transmission data including the ID number is transmitted. is required. Therefore, it is desirable to turn on the power of the automobile model 3 before the radio device 2 with a time longer than the timer for time over.

  Through the above processing, unique ID numbers that do not overlap with other sets are set independently for both the wireless device 2 and the car model 3. Thereafter, as a normal operation, an ID number is included in the transmission data transmitted from the radio 2 every time, and the operation of the model 3 is controlled based on the transmission data including the ID number that matches its own ID number. Will come to be.

  The present invention is not limited to the above form and may be implemented in various forms. For example, the automobile model 3 in this embodiment does not have a transmission function, but may have a transmission function. In this case, following the time length T1 given as the transmission time of the data transmitted from the wireless device 2, the time length as the transmission time of the data transmitted from the vehicle model 3 associated with the wireless device 2 T3 is set, and a time obtained by adding the time length T1 and the time length T3, for example, the time length T4 may be set as the transmission time given to the remote control toy system 1. In this case, the cycle of the transmission timing is four times the time length T4.

  Further, in this embodiment, when it is determined that there are a plurality of unused ID numbers in the wireless device 2, it is selected as its own ID number in the order of 1, 3, 2, 4; For example, it may be the largest unused ID number or may be determined randomly. Each of the wireless device 2 and the car model 3 in this embodiment stores its own ID number in the RAMs 13 and 23, but may be stored in a storage medium that retains the stored contents even when the power is turned off. In this case, the wireless device 2 is set so that transmission data is not transmitted until its own ID number is set after the power is turned on, and the vehicle model 3 operates according to the transmission data when detecting the ID number in use. You should set it not to.

  In the remote control toy system 1 according to the present embodiment, four types of ID numbers are prepared, and a maximum of four car models 3... 3 can be remotely operated, but four or more types of ID numbers may be used. Further, although infrared rays are used as a carrier wave of transmission data, the present invention is not limited to this, and an example is radio waves. In the present embodiment, the automobile model 3 is applied as the driving device. However, the present invention is not limited to this, and any device may be used as long as its operation is controlled by control information transmitted from the wireless device 2 such as a robot, a ship, and a doll.
