Description

  The present invention relates to a data communication method between a plurality of terminal devices and a control device that controls these terminal devices, a data communication device comprising a plurality of terminal devices and a control device that controls these terminal devices, and a plurality of A question-taking device that issues a question to each participant, and an operation unit that is operated by each participant to select an answer to the question, and the answer data selected by the operation of the operation unit The present invention relates to a totaling device composed of a plurality of answer data transmitting devices that respectively transmit to each other.

  For example, in a TV quiz program or a questionnaire survey at an event venue, a counting device is used that gives questions with options to a plurality of participants and counts the answers selected from the options by each participant. Yes.

  The tabulation device normally selects a questioning device that issues a question to a plurality of participants, and selects an answer to the question that is given to each participant from the options, and transmits the selected answer data to the questioning device Answer data transmitting device.

  However, conventionally, the question-taking device and the plurality of answer data transmitting devices are connected by a wire such as a cable.

  Therefore, when installing the counting device in, for example, a studio or an event venue, a cable has to be routed, and the worker is forced to make a great effort. The same applies not only at the time of installation but also at the time of removal work or when the arrangement of the question-taking device or the answer data transmitting device is changed. In addition, there is a problem that the floor and the like are cluttered by cables.

  Furthermore, in the case of cable connection, there are restrictions on the transmission distance and the number of connected devices. For example, it is very difficult to perform aggregation processing for a large venue and a large number of participants. There was a problem that was limited.

  Thus, as a technique for solving the above-described problem associated with cable connection, the conventional technique disclosed in Patent Document 1 can be cited. Patent Document 1 is a janken battle game realization system in which a janken battle server and a plurality of terminal devices such as personal computers and mobile devices are connected via a communication network, and participants play a janken battle game. In this case, the communication network is configured by radio.

  However, in the janken battle game realization system of Patent Document 1, there is a concern that the hand data is collided by hand data being simultaneously transmitted from a plurality of terminal devices onto the communication medium, and the hand data is damaged. Since the hand data is not transmitted to the janken battle server as it is, it is necessary to wait for a predetermined time and then transmit the hand data to the janken battle server again when a collision occurs.

  However, in the case of the counting device that has a very high possibility of collecting a lot of answer data at the same time, the probability that collision will occur further increases. Therefore, there is a concern that the transmission efficiency of the communication medium will be remarkably lowered because the opportunity to retransmit the answer data increases.

  The aggregation device 10 including the data communication device according to the present embodiment is basically configured as described above, and the operation thereof will be described in detail below.

  First, as a first operation example, using the counting device 10, an organizer who operates the questioning device 12 and a plurality of participants who operate the answer data transmitting devices 16 (1) to 16 (n). Take as an example the case of playing a janken game.

  In this janken game, the organizer, that is, the questioning device 12 is a parent, a plurality of participants, that is, each answer data transmitting device 16 (1) to 16 (n) is a child, and the janken is between the parent and the child. Assumed to be performed. A case where three participants A, B, and C participate in this janken game will be described as an example. Hereinafter, the answer data transmitting devices 16 (1) to 16 (n) operated by the participants A, B, and C will be referred to as answer data transmitting devices 16 (A) to 16 (C), respectively.

  Prior to the janken game, each of the answer data transmitting devices 16 (A) to 16 (C) is assigned a unique device identification number 1, 2, and 3 in advance. Specifically, the device identification numbers 1, 2, and 3 are stored in predetermined areas of the memory devices of the control units 80, respectively.

  FIG. 5 shows a specific setting example of the problem information data 40A related to the janken game. These data will be described sequentially. Unlike the quiz, there is no correct answer in the janken game, so nothing is stored in the correct data 46. Further, although the processing result data 50 is set in the problem information data 40A shown in FIG. 5, the problem information data 40A in this case indicates the data after the game ends, and naturally, before the game starts. No data is set in the processing result data 50.

  Through the preprocessing as described above, a janken game using the counting device 10 is started. Hereinafter, the processing procedure of this janken game will be described based on the flowchart shown in FIG.

  First, the question-taking device 12 displays a list of problem data 42 of the problem information data 40 stored in the problem information data storage unit 22 on the display unit 26. In this case, if the problem is only the janken game, the problem data 42 displayed on the display unit 26 is only the janken game. Next, the organizer who operates the questioning device 12 operates the selection switch 60 to select this janken game, and then presses the decision switch 62 to determine the execution of the janken game (step S1).

  Next, the control unit 20 accesses the problem information data storage unit 22, acquires the program [1] (see FIG. 5) stored in the processing program 44 of the problem information data 40A, and based on this processing program [1]. Execute the process. That is, since the program [1] instructs to generate the parent's hand, the control unit 20 drives a parent generator (not shown) including a random number generator and the like that it has to determine the parent's hand. Then, the determined hand is stored in the processing result data 50 (step S2). In this case, it is assumed that the determined parent's hand is goo (see processing result data 50 in FIG. 5).

On the other hand, each answer data transmitting device 16 (A) to 16 (C) performs preprocessing for generating a transmission timing signal (step S3). Specifically, first, each control unit 80 of the answer data transmitters 16 (A) to 16 (C) has different delay times TA, TB, TC for each answer data transmitter 16 (A) to 16 (C). Are calculated respectively. Each delay time TA, TB, TC is calculated from the following calculation formula (1).
Delay time TA to TC [ms] = k * device identification number [ms] (k = constant) (1)

  The constant k in the calculation formula (1) is set to a time value equal to or greater than the maximum transmission time of one record (also referred to as a command, data, or packet) on the communication medium, in this embodiment, the radio 14. In the present embodiment, the following description will be made assuming that the constant k = 30 [ms].

  Further, as described above, since the device identification numbers of the respective answer data transmitting devices 16 (A) to 16 (C) are 1, 2, and 3, respectively, substituting these values into the calculation formula (1), respectively, The delay times TA, TB, and TC are 30 [ms], 60 [ms], and 90 [ms], respectively. Each control unit 80 stores the calculated delay times TA, TB, and TC in the registers of its own delay time measurement unit 110, respectively.

  Next, each control unit 80 determines a signal generation period T1 common to all of the answer data transmitting devices 16 (A) to 16 (C), and stores this signal generation period T1 in a register of its own repetitive signal generation unit 112. To do. In the present embodiment, the signal generation period T1 is set to 100 [ms].

  Here, the control unit 20 of the questioning device 12 determines whether or not the start switch 64 has been pressed (step S4). When the start switch 64 is pressed, the control unit 20 starts the janken game. Specifically, the following processing is executed. First, the control unit 20 accesses the problem information data storage unit 22, acquires the voice information data 48 of the problem information data 40 </ b> A, and drives the voice output unit 28 based on the acquired voice information data 48. In other words, at the venue where the Janken game is being held, the voice guidance “All players, A, B, and C will start the Janken game. Announce the message (see FIG. 5). As a result, the start of the janken game is communicated to all participants in the venue. In this case, together with the voice guidance message, for example, the guidance message may be displayed as text information on a display board installed in the venue.

  Further, the control unit 20 drives the voice output unit 28 and announces a voice guidance message “operation number 1 is goo, operation number 2 is choki and operation number 3 is par”. As a result, the operation number is associated with the option. That is, when each participant operates the operation unit 84 and selects operation number 1, it means that he has selected Goo as a child's hand, and when operation number 2 is selected, he has selected choki, When number 3 is selected, par is selected.

  Next, the control unit 20 stores the time limit for accepting answer data from the answer data transmitting devices 16 (A) to 16 (C) in the register of the time measuring unit 31, and then issues a measurement start instruction by the time measuring unit 31. Start time measurement. In this embodiment, the reception limit time is set to 2 seconds.

  The control unit 20 creates a data transmission valid command 150 that is digital data, and outputs the created data transmission valid command 150 to the wireless communication unit 30. As shown in FIG. 7, the data transmission valid command 150 includes a start code 152 indicating the start of the command, a command code 154 indicating that this packet is the data transmission valid command 150, and an end code 156 indicating the end of the command. It consists of.

  The transmission unit 72 of the wireless communication unit 30 transmits the data transmission valid command 150 to the answer data transmission devices 16 (A) to 16 (C) (step S5). Specifically, the transmitter 72 modulates the data transmission valid command 150 that is digital data, then amplifies the modulated carrier wave, and radiates the amplified electrical signal from the antenna 70 as a radio wave.

  The radio waves radiated from the antenna 70 of the questioning device 12 are simultaneously received by the antennas 96 of the answer data transmitting devices 16 (A) to 16 (C) (see time T0 in FIG. 8 / step S6). Thereafter, a data transmission valid command 150 which has been amplified and demodulated by the receiving unit 98 and converted into digital data is output to the control unit 80.

  When the data transmission valid command 150 is input from the receiving unit 98, each control unit 80 generates a data transmission timing signal for each of the answer data transmitting devices 16 (A) to 16 (C) (step S7). Specifically, each control unit 80 first instructs the own delay time measurement unit 110 to start measuring each delay time TA to TC. In the above description, the time when the data transmission valid command 150 is received is not necessarily limited to the time T0. The same predetermined data is transmitted from the time T0 to all the answer data transmitting devices 16 (A) to 16 (C). It may be a point in time. For example, it may be the time when the end code 156 of the data transmission valid command 150 is received.

  Next, each control unit 80 determines whether or not a measurement end signal is input from each delay time measurement unit 110, and generates a repetitive signal to the repetitive signal generation unit 112 when a measurement end signal is input. Give instructions to do.

  That is, as shown in FIG. 8, the data transmission timing signal of the answer data transmitting device 16 (A) is repeatedly generated at the signal generation period T1 = 100 [ms] after the delay time TA = 30 [ms] from the time T0. The data transmission timing signal of the answer data transmitting device 16 (B) becomes a signal repeatedly generated at the signal generation period T1 = 100 [ms] after the delay time TB = 60 [ms] from the time point T0. The data transmission timing signal of the data transmission device 16 (C) is a signal repeatedly generated at the signal generation cycle T1 = 100 [ms] after the delay time TC = 90 [ms] has elapsed from the time T0.

  Each control unit 80 starts counting up the time counter of the operation time measuring unit 90 when the data transmission valid command 150 is received.

  Next, each control unit 80, as shown in FIG. 9, includes a start code 162 indicating the start of the command, a data code 164 indicating that this packet is receipt confirmation data, and an end code 166 indicating the end of the command. Is generated, and the generated reception confirmation data 160 is transmitted to the question-taking device 12 via the radio 14 in synchronization with its own transmission timing signal (step S8).

  In this case, each of the receipt confirmation data 160 (A) to 160 (C) has a transmission time of less than 30 [ms] as described above, and, as can be understood from FIG. Since the data is transmitted to the questioning device 12 in synchronization with the transmission timing signal, collision between data on the communication medium (wireless 14 in the present embodiment) is avoided. Therefore, it is possible to eliminate the need for data retransmission accompanying collision, and as a result, it is possible to improve the transmission efficiency of the communication medium.

  The questioning device 12 receives the receipt confirmation data 160 (A) to 160 (C) from the answer data transmitting devices 16 (A) to 16 (C) (step S9), analyzes the receipt confirmation data, and answers data. It is confirmed whether or not the transmitters 16 (A) to 16 (C) and the radio 14 are operating normally.

  On the other hand, each control unit 80 of the answer data transmitting devices 16 (A) to 16 (C) determines whether or not the determination switch 94 connected to itself is operated (step S10), and the determination switch 94 is pressed. When the determination is made, the answer data 180 shown in FIG. 10 is created, and the created answer data 180 is transmitted to the questioning device 12 (step S11).

  The answer data 180 includes a start code 182 indicating the start of data, device identification number data 184 that is data of device identification numbers 1 to n, and a data transmission valid command 150 until the decision switch 94 is operated. Operation time data 186, operation number data 188 which is data of operation numbers 1 to n determined by the determination switch 94, and an end code 190 indicating the end of the data.

  In this case, each control unit 80 of the answer data transmitting devices 16 (A) to 16 (C) reads the device identification number stored in its own memory device and stores it in the device identification number data 184. Each control unit 80 accesses the time counter of the operation time measuring unit 90 connected to itself, acquires the count number at this point, that is, time data (= count number × reference clock), and operates time data. It is stored in 186.

  FIG. 11 shows a specific setting example of the answer data 180 (A) to 180 (C) for each of the answer data transmitting devices 16 (A) to 16 (C). By the way, the black star ★ in FIG. 8 indicates the timing when the determination switch 94 is pressed. That is, as can be understood from FIG. 8, the answer data transmitting devices 16 (A) and 16 (B) are pressed by the decision switch 94 when 190 [ms] has elapsed from the time T0 when the data transmission valid command 150 is received. In the answer data transmitting apparatus 16 (C), the determination switch 94 is pressed when 350 [ms] has elapsed from the time T0.

  Therefore, as shown in FIG. 11, 190 [ms], 190 [ms], and 350 [ms] are stored in the operation time data 186 of the respective answer data 180 (A) to 180 (C). In addition, it is assumed that each of the participants A to C has selected operation number 1 = Goo, operation number 2 = choki, and operation number 3 = par as child hands.

  Each control unit 80 transmits the answer data 180 (A) to 180 (C) created as described above to the questioning apparatus 12 via the radio 14 in synchronization with its own transmission timing signal.

  In this case, as described above, the answer data transmitting device 16 (A) has pressed the decision switch 94 when 190 [ms] has elapsed from the time T0 when the data transmission valid command 150 is received. As shown in FIG. 8, A) is transmitted to the questioning device 12 in synchronization with the third rising edge of the transmission timing signal (when 230 [ms] has elapsed from time T0).

  Further, as described above, the answer data transmitting device 16 (B) has the decision switch 94 pressed when 190 [ms] has elapsed from the time T0, and the answer data 180 (B) is as shown in FIG. At the same time, the transmission timing signal is transmitted to the questioning device 12 in synchronization with the third rising edge (when 260 [ms] has elapsed from time T0).

  Further, as described above, the answer data transmitting device 16 (C) has the decision switch 94 pressed when 350 [ms] has elapsed from the time T0, and the answer data 180 (C) is as shown in FIG. Are transmitted in synchronization with the fourth rising edge of the transmission timing signal (when 390 [ms] has elapsed from time T0).

  In this case, as described above, each answer data 180 (A) to 180 (C) has a transmission time of less than 30 [ms], and, as can be understood from FIG. Since the data is transmitted to the questioning device 12 in synchronization with the transmission timing signal, collision between data on the communication medium (wireless 14 in the present embodiment) is avoided. Therefore, it is possible to eliminate the need for data retransmission accompanying collision, and as a result, it is possible to improve the transmission efficiency of the communication medium.

  The questioning device 12 receives each answer data 180 (A) to 180 (C) from each answer data transmitting device 16 (A) to 16 (C) (step S12), and then executes a counting process (step S12). S13).

  Here, the aggregation process (step S13) will be described. The control unit 20 of the questioning device 12 accesses the problem information data storage unit 22 and acquires the programs [2] and [3] (see FIG. 5) stored in the processing program 44 of the problem information data 40A. Processing based on the programs [2] and [3] is executed.

  That is, according to the programs [2] and [3], the parent's hand and the hands of the children A, B, and C are respectively compared, and the parent wins when the parent wins or draws, When the child wins, the child wins. Therefore, in this case, the parent hand is determined to be goo in step S2, and the hands of each child A, B, and C are choki, goo, and par, respectively, so the processing result of the problem information data 40A The data 50 stores child A = losing, child B = losing, and child C = winning.

  Next, as shown in FIG. 12, the control unit 20 determines the start code 202 and the processing result data 50 of the problem information data 40 (specifically, child A = losing, child B = losing, child C = winning). And the total processing result data 200 composed of the end code 204, and transmit the generated total processing result data 200 to the answer data transmitting devices 16 (A) to 16 (C) ( Step S14).

  Each answer data transmitting device 16 (A) to 16 (C) receives this total processing result data 200 (step S15), and displays it on its display unit 82 (step S16). Accordingly, each of the participants A to C can know a parent's hand or whereabouts of janken. Therefore, interest in the janken game increases and the game can be excited.

  By the way, as described above, the questioning device 12 sets the reception limit time of the answer data 180 (A) to 180 (C) to 2 seconds (the reception limit time set in the register of the time measuring unit 31 is 2 seconds). ). In the above, since all the answer data 180 (A) to 180 (C) are transmitted within 2 seconds, it does not correspond to the above-mentioned acceptance restriction, but for example, it is too late to press the decision switch 94. When there is a participant, it is possible to perform aggregation in a short time without waiting for the answer data 180 from the participant by providing the above reception restriction. That is, the janken game can be executed speedily, and the game can be further increased.

  The above is the description of the first operation embodiment. Next, a second operation example will be described. In the second operation example, using the totaling device 10, between the organizer who operates the questioning device 12 and a plurality of participants who operate the answer data transmitting devices 16 (1) to 16 (n). This is a quick press quiz.

  In this quick-press quiz, the organizer, that is, the questioning device 12 is set as the questioning person, and the plurality of participants, that is, the answer data transmitting devices 16 (1) to 16 (n) are set as answerers, and which answerer is correct. Compete for quick answers. The case where three answerers A, B, and C participate in this quick-press quiz is described below as an example. The answer data transmitting devices 16 (1) to 16 (n) operated by these answerers A, B, and C are referred to as answer data transmitting devices 16 (A) to 16 (C), respectively.

  Prior to the quick-press quiz, each answer data transmitting device 16 (A) to 16 (C) is given a unique device identification number 1, 2, 3 in advance. It is the same as the case of.

  FIG. 13 shows a specific setting example of the problem information data 40B related to this quick-press quiz. These data will be described sequentially.

  Through the preprocessing as described above, a quick press quiz using the counting device 10 is started. Hereinafter, based on the flowchart shown in FIG. 14, the quick-press quiz processing procedure will be described. The description of the process shown in the flowchart of FIG. 14 that is the same as the process shown in the flowchart of FIG. 6 is omitted.

  First, the question-taking device 12 displays a list of problem data 42 of the problem information data 40 stored in the problem information data storage unit 22 on the display unit 26. Next, the organizer who operates the questioning device 12 operates the selection switch 60 to select this quick-press quiz, and then presses the determination switch 62 to determine execution of the quick-press quiz (step S1).

  Next, the control unit 20 accesses the problem information data storage unit 22, acquires the program [1] (see FIG. 13) stored in the processing program 44 of the problem information data 40B, and based on this processing program [1]. Execute the process. That is, the control unit 20 loads the content (answer: red) of the correct answer data 46 into its own memory device (step S2). The process in step S3 is the same as step S3 in FIG.

  The control unit 20 of the questioning device 12 determines whether or not the start switch 64 has been pressed (step S4). When the start switch 64 is pushed, the control unit 20 starts a quick push quiz. Specifically, the following processing is executed. First, the control unit 20 accesses the problem information data storage unit 22 to acquire the audio information data 48 of the problem information data 40B, and drives the audio output unit 28 based on the acquired audio information data 48. In other words, at the venue where the quick push quiz is being held, for all participants A, B and C, “Start the quick push quiz. This is a problem. “Operation number 1 = Orange, Operation number 2 = Pink, Operation number = Red. Please operate your own operation unit and decide your hand.” A voice guidance message is announced (see FIG. 13).

  Next, the control unit 20 stores the answer data reception limit time = 5 seconds from the answer data transmitting devices 16 (A) to 16 (C) in the register of the time measuring unit 31, and then issues a measurement start instruction. Time measurement by the measurement unit 31 is started. The processing in steps S5 to S9 is the same as that in steps S5 to S9 in FIG.

  On the other hand, each control unit 80 of the answer data transmitting devices 16 (A) to 16 (C) determines whether or not the determination switch 94 connected to itself is operated (step S10), and the determination switch 94 is pressed. When the determination is made, the answer data 180 shown in FIG. 10 is created, and the created answer data 180 is transmitted to the questioning device 12 (step S11).

  FIG. 15 shows a specific setting example of the answer data 180 (A) to 180 (C) for each of the answer data transmitting devices 16 (A) to 16 (C). By the way, in FIG. 16, the white star mark ☆ indicates the timing when the determination switch 94 is pressed. That is, as can be understood from FIG. 16, the answer data transmitting device 16 (A) presses the decision switch 94 when 200 [ms] elapses from the time T0 when the data transmission valid command 150 is received, and transmits the answer data. In the device 16 (B), the decision switch 94 is pressed when 190 [ms] has elapsed from the time T0, and in the answer data transmitting device 16 (C), the switch 94 is pressed when 160 [ms] has elapsed from the time T0. Has been. Therefore, as shown in FIG. 15, 200 [ms], 190 [ms], and 160 [ms] are stored in the operation time data 186 of the respective answer data 180 (A) to 180 (C).

  In addition, operation number 2 (peach), operation number 3 (red), and operation number 3 (red) are stored in the operation number data 188 of each answer data 180 (A) to 180 (C).

  Each control unit 80 transmits the answer data 180 (A) to 180 (C) created as described above to the questioning apparatus 12 via the radio 14 in synchronization with its own transmission timing signal.

  In this case, the answer data transmitting device 16 (A), as described above, has pressed the decision switch 94 when 200 [ms] has elapsed from the time T0 when the data transmission valid command 150 is received. As shown in FIG. 16, A) is transmitted to the questioning device 12 in synchronization with the third rising edge of the transmission timing signal (when 230 [ms] has elapsed from time T0).

  Further, as described above, the answer data transmitting device 16 (B) has the decision switch 94 pressed when 190 [ms] has elapsed since the time T0, and the answer data 180 (B) is as shown in FIG. At the same time, the transmission timing signal is transmitted to the questioning device 12 in synchronization with the third rising edge (when 260 [ms] has elapsed from time T0).

  Further, as described above, the answer data transmitting device 16 (C) has the decision switch 94 pressed when 160 [ms] has elapsed from the time T0, and the answer data 180 (C) is as shown in FIG. Are transmitted in synchronization with the second rising edge of the transmission timing signal (at the time when 190 [ms] has elapsed from time T0).

  In this case, it is needless to say that collision between data on the communication medium (wireless 14 in the present embodiment) is avoided, and data retransmission associated with the collision can be made unnecessary.

  The questioning device 12 receives each answer data 180 (A) to 180 (C) from each answer data transmitting device 16 (A) to 16 (C) (step S12), and then executes a counting process (step S12). S13).

  Here, the aggregation process (step S13) will be described. The control unit 20 of the questioning device 12 accesses the problem information data storage unit 22 to acquire the programs [2] to [4] (see FIG. 13) stored in the processing program 44 of the problem information data 40B. Processing based on the programs [2] to [4] is executed.

  First, the control unit 20 compares the operation time data 186 of the respective answer data 180 (A) to 180 (C), and sets the order in the order in which the decision switch 94 is pressed earlier (program [2]). As a result, as shown in the processing result data 50 of FIG. 13, first place = solver C, second place = solver B, third place = solver A. In this case, the order in which the questioning device 12 receives the answer data 180 (A) to 180 (C) is irrelevant.

  Next, the control unit 20 compares the correct answer data 46 = red loaded in its memory device with the answer of the answerer, that is, the operation number data 188 of each answer data 180 (A) to 180 (C). (Program [3]) and the result is stored in the problem information data 40B (see FIG. 13). That is, as understood from FIG. 13, answerer A = incorrect answer, answerer B, C = correct answer.

  Next, the control unit 20 executes a process in which the person who gave the correct answer earliest is the winner from the above results (program [4]). In this case, as understood from the processing result data 50 of FIG. 13, the answerer C who gave the correct answer earliest is the winner.

  Based on the processing result data 50 created as described above, the control unit 20 creates tabulation processing result data 200 in the format shown in FIG. 12, and the created tabulation processing result data 200 is sent to each answer data transmitting device 16 ( A) to 16 (C) (step S14).

  Each answer data transmitting device 16 (A) to 16 (C) receives this total processing result data 200 (step S15), and displays it on its display unit 82 (step S16).
