[0039]

[0041]
  In addition, as shown to Fig.8 (a), the wristwatch type thing is used for the 1st data communication apparatus 3 and the 2nd data communication apparatus 4. FIG. The transmission electrode 32 and the reception electrode 34 of the first data communication device 3 and the transmission electrode 42 and the reception electrode 44 of the second data communication device 4 are provided in the peripheral portion of the time display unit 55. The reference electrode 31 of the first data communication device 3 is disposed so as to be in contact with the human body 1, and the transmission electrode 32 and the reception electrode 34 are disposed so as not to be in contact with the human body 1. The reference electrode 41 of the communication device 4 is disposed so as to be in contact with the human body 2, and the transmission electrode 42 and the reception electrode 44 are disposed so as not to be in contact with the human body 2. FIG. 8B shows an electrode arrangement, where the human body 1 and the human body 2 shake hands, and bidirectional data communication is performed between the first data communication device 3 and the second data communication device 4. It shows the state.
[0042]
  The operation explanation is shown below. First, the human body 1 presses the communication start button of the first data communication device 3, and the human body 2 starts data communication by pressing the communication start button of the second data communication device 4.
[0043]
  First, an operation when the human body 1 selects the transmission / reception switching button 56 in the transmission mode and the human body 2 selects the transmission / reception switching button 57 in the reception mode is shown. When the transmission / reception switching button 56 enters the transmission mode, the power is turned on to the modulation unit 33 of the first data communication device 3, and the communication data 5 is transmitted through the transmission electrode 32. When the transmission / reception switching button 57 enters the reception mode, the demodulator 45 of the second data communication device 4 is turned on, and the signal input from the reception electrode 44 is received as data.
[0044]
  Next, an operation when the human body 1 selects the transmission / reception switching button 56 in the reception mode and the human body 2 selects the transmission / reception switching button 57 in the transmission mode will be described. When the transmission / reception switching button 57 enters the transmission mode, the power is turned on to the modulation unit 43 of the second data communication device 4, and the communication data 5 is transmitted through the transmission electrode 42. When the transmission / reception switching button 56 enters the reception mode, the demodulator 35 of the first data communication device 3 is turned on, and the signal input from the reception electrode 34 is received as data.
[0045]
  In such a data communication system, both the first data communication device 3 and the second data communication device 4 have a transmission / reception function, and the human body 1 and the second data communication device 4 to which the first data communication device 3 is attached. Since the human body 2 wearing the switch switches the transmission / reception switching button 56 and the transmission / reception switching button 57 and selects transmission / reception, bidirectional data communication between the first data communication device 3 and the second data communication device 4 is performed. It can be performed.
[0046]
  Further, FIG. 9 shows a configuration of a data communication apparatus provided with a modulation / demodulation switching unit 58 and a modulation / demodulation switching unit 59 described later. The modulation / demodulation switching unit 58 is provided in the first data communication device 3 and switches the connection between the modulation unit 33 and the demodulation unit 35 in accordance with the transmission mode and reception mode of the transmission / reception switching unit 36 selected by the transmission / reception switching button 56. It has a function. Therefore, the transmission electrode 32 and the reception electrode 34 in FIG. 7 can be shared as the communication electrode 300. Similarly, the modulation / demodulation switching unit 59 is provided in the second data communication apparatus 4, and the modulation unit 43 and the demodulation unit 45 are matched with the transmission mode and reception mode of the transmission / reception switching unit 46 selected by the transmission / reception switching button 57. Therefore, the transmission electrode 42 and the reception electrode 44 in FIG. 7 can be shared as the communication electrode 400.
[0047]
  Therefore, by sharing the transmission electrode and the reception electrode in this way, the number of electrodes can be reduced and the area of one electrode can be increased, so that the reception sensitivity of communication data is also increased, and a data communication system with high communication accuracy. Can be provided.
[0048]
  First of the present invention1The embodiment will be described with reference to FIG. FIG. 10 shows the first aspect of the present invention.1It is a block diagram which shows the data communication apparatus which concerns on embodiment. The schematic diagram showing the data communication system and the schematic diagram showing the data communication device areReference example6 and 8 are the same as those in FIG.
[0049]
  As shown in FIG. 10A, the first data communication device 3 is obtained by adding a random number generation unit 39 and a contact detection unit 60 except for the transmission / reception switching button 56 in FIG. 7A. Further, as shown in FIG. 10B, the second data communication device 4 is obtained by adding a random number generator 49 and a contact detector 61 except for the transmission / reception switching button 57 in FIG. 7B. .
[0050]
  First1In the embodiment, when the contact detection unit 60 and the contact detection unit 61 detect that the human body 1 and the human body 2 are in contact, the random number generation unit 39 and the random number generation unit 49 each generate a random number.
[0051]
  The contact detection unit 60 and the contact detection unit 61 have a function of detecting that a human body is in contact, and detect that the human body 1 and the human body 2 are in contact with each other.
[0052]
  The random number generation unit 39 and the random number generation unit 49 have a function of generating a random number and automatically switching the transmission / reception modes of the transmission / reception switching unit 36 and the transmission / reception switching unit 46 according to the random number. For example, if the random number is an odd number, it is assumed that the data communication device is on the transmission side, and if the random number is an even number, the number is assigned in advance so that it is the data communication device on the reception side. This is a method of switching the transmission / reception modes of the transmission / reception switching unit 36 and the transmission / reception switching unit 46 according to the numbers assigned in advance to the values of the random numbers generated by the units 49.
[0053]
  Here, when the random numbers generated by the random number generation unit 39 and the random number generation unit 49 are both odd numbers, the first data communication device 3 and the second data communication device 4 are both on the transmission side. Data 5 stays in the reception electrode 34 and the reception electrode 44 because the demodulation unit 35 and the demodulation unit 45 do not function. In such a case, for example, a function for detecting the communication data 5 stagnated in the reception electrode 34 and the reception electrode 44 is added to the transmission / reception switching unit 36 and the transmission / reception switching unit 46, and the transmission / reception switching unit 36 and the transmission / reception switching unit 36. When the switching unit 46 detects the communication data 5, the random number generation unit 39 and the random number generation unit 49 generate random numbers again to determine the transmission / reception side.
[0054]
  When the random numbers generated by the random number generator 39 and the random number generator 49 are both even, the first data communication device 3 and the second data communication device 4 are both on the receiving side. The demodulation unit 35 and the demodulation unit 45 cannot detect the communication data 5. In such a case, for example, the demodulating unit 35 and the demodulating unit 45 are provided with a timer function, and if the demodulating unit 35 and the demodulating unit 45 cannot detect the communication data 5 even after a predetermined time, the random number generating unit 39 and the random number generating unit The random number is generated again by the unit 49 and the transmission / reception side is determined.
[0055]
  The random number distribution is not limited to the odd-numbered and even-numbered distribution, and it is of course possible to distribute the random numbers between the transmitting side and the receiving side. Also, the absolute values of the random number values generated by each of the random number generation unit 39 and the random number generation unit 49 are compared, the data communication device on the random number generation unit side having a large absolute value is set as the transmission side, and the other data communication devices are Of course, other comparison methods such as a method on the receiving side may be used.
[0056]
  Further, when communication time information for transmitting / receiving the communication data 5 is added in advance to the random numbers assigned to the transmission side and the reception side, and data communication is performed for the communication time, the random number generation unit 39 and the random number generation unit 49 may be configured to perform bidirectional data communication by automatically switching the original transmission / reception mode to a mode different from the original mode.
[0057]
  The operation explanation is shown below. For example, when the contact detection unit 60 of the first data communication device 3 is activated before the contact detection unit 61 of the second data communication device 4, the contact detection unit 60 selects the transmission / reception switching button 56 as the transmission mode. The contact detection unit 61 selects the transmission / reception switching button 57 as the reception mode. After this, the thirdReference exampleThe communication data 5 is transmitted from the first data communication device 3 to the second data communication device 4 although the description is omitted because it is the same as the operation described above.
[0058]
  Further, when the contact detection unit 61 of the second data communication device 4 operates before the contact detection unit 60 of the first data communication device 3, the second data communication device 4 performs the first operation similarly to the above-described operation. Communication data 5 data is transmitted to the data communication device 3.
[0059]
  Next, when the contact detection unit 60 of the first data communication device 3 and the contact detection unit 61 of the second data communication device 4 are operated simultaneously or substantially simultaneously, the random number of the first data communication device 3 is simultaneously with this operation. The generator 39 and the random number generator 49 of the second data communication device 4 generate random numbers, and if the random numbers generated by each of the random number generator 39 and the random number generator 49 are odd numbers, the data communication device on the transmission side is assumed. If the random number is an even number, the transmission / reception mode of the transmission / reception switching unit 36 and the transmission / reception switching unit 46 is switched as a data communication device on the receiving side.
[0060]
  In this manner, one of the first data communication device 3 and the second data communication device 4 is set as the transmission side, and the other is set as the reception side, so that communication is performed from one data communication device to the other data communication device. Data 5 is transmitted.
[0061]
  Of course, the transmission / reception switching unit 36 and the transmission / reception switching unit 46 may have a function of automatically switching the transmission / reception mode at the same time as the time required for transmission of the communication data 5 elapses. In such a configuration, the data communication device that was originally the transmission side of data communication is automatically switched to the data communication device on the reception side, and the data communication device that was the reception side is automatically switched to the transmission side. The data communication apparatus can be switched to two-way data communication.
[0062]
  However, in this case, the communication data 5 is preliminarily incorporated with time information required for completion of transmission of the communication data 5, and the determination to control the transmission / reception switching unit 36 and the transmission / reception switching unit 46 by determining the time information. It is necessary to provide a unit (not shown) in the transmission / reception switching unit 36 and the transmission / reception switching unit 46.
[0063]
  In such a data communication system and data communication device, the data communication device has a function capable of both transmission and reception, and the contact detection unit 60 of the first data communication device 3 and the contact detection of the second data communication device 4. The unit 61 detects that the human body 1 and the human body 2 are in contact, and the random number generation unit 39 and the random number generation unit 49 determine the combination of transmission and reception. Therefore, between the first data communication device 3 and the second data communication device 4 Can automatically start two-way data communication. Further, since the data communication device has a function capable of both transmission and reception, versatility as a data communication device is improved.
[0064]
  The thirdReference exampleAnd the second1In the embodiment, of course, the first data communication device 3 includes an oscillation unit (not shown) that generates an AC signal, and a voltage corresponding to the modulation signal modulated by the modulation unit 33 with the reference electrode 31 and the transmission electrode 32.
