The embodiment described below includes a portable child device constituting a parent-child phone and a charging device that charges a rechargeable secondary battery built in the child device when the child device is placed. And an embodiment in which the present application is applied to a charging system constituted by

  FIG. 1 is a block diagram illustrating a schematic configuration of the charging system according to the embodiment, and FIG. 2 is a diagram illustrating a format related to data transmission between the charging device and the slave in the embodiment.

  As shown in FIG. 1, the charging system S according to the embodiment can be wirelessly connected to a parent device (not shown), and can be connected to an external telephone line via the parent device. Moreover, it is comprised by the small subunit | mobile_unit 10 which can be portable, and the charging device 30 which charges the secondary battery mentioned later in the said subunit | mobile_unit 10 when the said subunit | mobile_unit 10 is mounted.

  Next, the slave unit 10 includes a communication unit 11 connected to an antenna AT used for wireless communication with a master unit (not shown), a CPU 12 as an example of an execution unit, a display unit 13 including a liquid crystal display, Electrical and physical connection between the speaker 14, the microphone 15, an operation unit 16 (not shown) or a so-called jog dial, a charge detection unit 17, the secondary battery 18, and the charging device 30. And charging terminals 19 and 20 as an example of supply means used in the above.

  In this configuration, the communication unit 11 of the child device 10 is connected to the parent device via the antenna AT under the control of the CPU 12 and controls data exchange related to a call with the outside via the parent device.

  Then, the CPU 12 controls the communication unit 11 or the like as the slave unit 10 constituting the parent / child phone so as to make a call to a telephone number designated by an operation using an operation button or the like in the operation unit 16, for example. When a call is established with the other party, the voice sent from the other party through the master unit is emitted from the speaker 14 and the voice of the user of the slave unit 10 is transmitted through the microphone 15. If it is input, it is encoded and transmitted to the other party via the base unit. In this control operation, necessary information such as the telephone number of the other party is displayed on the display unit 13 under the control of the CPU 12, and necessary data is temporarily stored in a memory (not shown) in the CPU 12. The

  On the other hand, when a charging voltage is applied to the secondary battery 18 from the charging device 30 via the charging terminals 19 and 20, a necessary amount of charging is thereby performed. And the said secondary battery 18 supplies the charged electric power to each said structural member which comprises the subunit | mobile_unit 10, and drives the said structural member.

  In parallel with this, the charging detector 17 applies the charging voltage to the charging terminals 19 and 20 (that is, is applied to the charging terminals 19 and 20) by placing the slave unit 10 on the charging device 30. When the charging voltage is turned on), the fact that it is turned on is detected, and the detection result is output to the CPU 12. Further, the secondary battery 18 is charged by the applied charging voltage.

  On the other hand, when the charging device 17 is removed from the charging device 30 and the application of the charging voltage to the charging terminals 19 and 20 is turned off, the charging detection unit 17 detects that the charging device is turned off, and the detection result Is output to the CPU 12. Further, the charging of the secondary battery 18 is stopped when the application of the charging voltage is turned off.

  In addition, CPU12 which detected ON / OFF of the charging voltage based on the detection result in the charge detection part 17 detects that the said charging voltage was turned on, for example, the subunit | mobile_unit 10 is mounted on the charging device 30. It is recognized that the call has been made, and control for terminating the call by the child device 10 is performed. The CPU 12 detects that the charging voltage has been turned off, for example, recognizes that the child device 10 has been removed from the charging device 30, and performs control for starting a call by the child device 10.

  In addition to this, in the handset 10 according to the embodiment, by using the above-described charging voltage on / off detection function included in the charging detection unit 17 as it is, charging is performed by turning on / off the charging voltage as described later. On / off switching of the charging voltage as operation information transmitted from the device 30 is detected by the charging detection unit 17, and the detection result is output to the CPU 12.

  Thereby, CPU12 recognizes the content of the said operation information transmitted from the charging device 30 based on the said detection result from the charge detection part 17, in addition to the normal call operation etc. as the subunit | mobile_unit 10 mentioned above, Each component of the subunit | mobile_unit 10 is controlled so that the said content may be implement | achieved.

  On the other hand, as shown in FIG. 1, the charging device 30 according to the embodiment includes an operation unit as an example of an operation unit including operation buttons 37 of the same type as the operation buttons included in the operation unit 16 in the slave unit 10. 35, a CPU 34, a charge control unit 33 as an example of a control means connected to a plug 36 for receiving power supply from a household outlet of AC 100 volts, for example, and charging terminals 19 and 20 in the slave unit 10 And charging terminals 31 and 32 as an example of charging means respectively used for electrical and physical connection between them.

  In this configuration, the charging terminal 31 is connected to the charging control unit 33, while the charging terminal 32 is grounded.

  In addition, the operation buttons 37 and the like included in the operation unit 35 include the same number of the same types as the operation buttons and the like included in the operation unit 16 of the slave unit 10 in the operation unit 35. Further, for example, the number and type of operation buttons 37 limited as compared with the operation unit 16 may be used, such as only those used for the call function. Furthermore, buttons that are not included in the operation unit 16 (more specifically, buttons or the like that are defined so that operations realized by pressing a plurality of buttons on the child device 10 can be collectively operated, for example) are displayed on the operation unit 35. You may arrange in. The size of the operation button 37 included in the operation unit 35 is larger than that of the operation button included in the operation unit 16, and the structure is easier to operate than the operation button included in the operation unit 16. It is structured.

  The CPU 34 generates the operation information corresponding to the operation performed using the operation button 37 or the like in the operation unit 35 and outputs the operation information to the charge control unit 33.

  Next, the charging control unit 33 converts the alternating current input through the plug 36 into the charging voltage having a predetermined voltage for charging the secondary battery 18 and supplies the charging voltage to the charging terminal 31. The secondary battery 18 is charged. In addition, the charging control unit 33 according to the embodiment converts (modulates) the charging voltage as described later using the operation information, and supplies the converted voltage to the charging terminal 31. When the handset 10 is placed on the charging device 30 and the charging terminal 19 and the charging terminal 31 come into contact with each other and the charging terminal 20 and the charging terminal 32 come into contact with each other, the charging voltage modulated by the operation information is changed to the child terminal. The voltage is applied to the secondary battery 18 and the charge detection unit 17 in the machine 10. As a result, the secondary battery 18 is charged, and the content of the operation information is detected by the charge detection unit 17. The control of the CPU 12 of the slave unit 10 based on the secondary battery 18 detects the content according to the content of the operation information. The machine 10 operates.

  A so-called alternating current (AC) adapter is interposed between the plug 36 and the charging control unit 33, and the AC power from the household outlet is converted into a direct current corresponding to the charging voltage in the AC adapter, and the charging control unit 33 It can also be configured to supply. In this case, the charging control unit 33 performs only the following charging voltage conversion (modulation) operation.

  Next, the charging voltage modulation method according to the operation information by the charging control unit 33 will be described with reference to FIG.

  First, a first specific example of the modulation method will be described with reference to FIGS. 2 (a) and 2 (b).

  As a first specific example of the modulation method, a so-called asynchronous serial communication system in which “off” of the charging voltage corresponds to data “0” and “on” of the charging voltage corresponds to data “1” is used. The operation information is transmitted from the charging device 30 to the child device 10 mounted on the 8-bit code data as a unit.

  More specifically, as illustrated in FIG. 2A, the start bit SB is used as the head, the 8-bit code data is formed by the data bits b0 to b7, and the parity bit P and the stop bit TB are further added. Thus, operation information for one unit is formed. Note that this operation information is assigned to one operation button 37 or the like included in the operation unit 35 of the charging device 30.

  As shown in FIG. 2B, frame start code data SC having a data structure similar to the data structure shown in FIG. 2A and having a fixed value indicating the start of the frame as its code data, The button code data BC corresponding to the operation information and the inverted code data RC having a value obtained by inverting “1” and “0” of each bit in the button code data BC constitute one frame, This frame is continuously transmitted from the charging device 30 to the slave unit 10 by the number of operated operation buttons 37 or the like. As a result, operation information corresponding to the content operated in the operation unit 35 of the charging device 30 is transmitted from the charging device 30 to the child device 10 and provided for operation of the child device 10.

  As the button code data BC, the button code data BC is uniquely assigned to each operation button 37 or the like. However, the most significant bit of the button code data BC is “ The range from “0” is assigned to the operation button 37 and the like.

  And in the charge detection part 17 which received the said flame | frame, when the structure of the flame | frame is what was illustrated in FIG.2 (b), it is the operation produced | generated based on operation of the operation part 35 in the charging device 30 It recognizes that it is information and outputs the operation information received together with that to the CPU 12. Thereby, the subunit | mobile_unit 10 will operate | move according to the content of the said operation information.

  Next, a second specific example of the modulation method will be described with reference to FIG.

  In the first specific example of the modulation method described above, the case of using the asynchronous serial communication system has been described. However, in the second specific example described below, the content of the operation information is transmitted by changing the number of pulses.

  As a second specific example of the modulation method, the number of pulses is uniquely assigned in advance to each piece of operation information related to the operation buttons 37 and the like included in the operation unit 35, and the assigned information is assigned. The correspondence between the number of pulses and the operation information is stored in a nonvolatile manner in a memory area (not shown) in the CPU 34 and the charge detection unit 17, respectively.

  As illustrated in FIG. 2C, when the timing at which any one of the operation buttons 37 is operated in the operation unit 35 is a timing BT, the symbol “α in a certain time from the timing (FIG. 2C). After the charging voltage is turned on, the charging voltage is turned on and off so that the pulse signal includes the number of pulses PL assigned to the operated operation button 37 or the like. By turning on the charging voltage for time (indicated by the symbol “β” in FIG. 2C), data transmission for one piece of operation information is performed from the charging device 30 to the child device 10. At this time, the pulse width of one pulse PL is set to be shorter than both of the predetermined times α and β.

  Then, by making this continuous, operation information corresponding to the content operated in the operation unit 35 of the charging device 30 is transmitted from the charging device 30 to the slave unit 10 as a pulse signal including the number of pulses PL corresponding to the content. Is done.

  Next, the charge detection unit 17 that receives the pulse signal as the operation information monitors the change in the charge voltage, and confirms that the charge voltage has been turned on for a certain period of time indicated by the symbol “α” in FIG. When detected, the number of pulses PL that follow is counted until it is detected that the charging voltage has been turned on for a certain period of time indicated by the symbol “β” in FIG. Thereafter, the operation information corresponding to the counted number of pulses PL is recognized by the charge detection unit 17 and output to the CPU 12. Thereby, the subunit | mobile_unit 10 will operate | move according to the content of the said operation information.

  Here, in the charging system S according to the embodiment, as described above, the period during which the charging voltage in the asynchronous serial communication system illustrated in FIGS. 2A and 2B is ON, or FIG. The secondary battery 18 is charged only in a period corresponding to the pulse width of the pulse PL illustrated in (c) (that is, a period in which the charging voltage is on).

  Therefore, in each period in which the charging voltage is on, the period in which the charging voltage is off correspondingly detects that the child device 10 is removed from the charging device 30 in the charge detection unit 17 of the child device 10. It is necessary to make the period so short that it does not occur. In addition to this, each period when the charging voltage is on needs to be set to a time length that does not unnecessarily increase the time until the charging of the secondary battery 18 is completed.

  In addition, since it is thought that the opportunity itself which should operate the subunit | mobile_unit 10 (it is charging) mounted in it using the operation button 37 etc. in the charging device 30 is not so frequent, the operation information which concerns on embodiment It is considered that there is no practical problem by setting each period with an emphasis on the point that the data is reliably transmitted.

  As described above, according to the operation of the charging system S according to the embodiment, the charging voltage is controlled based on the operation information input using the operation unit 35 provided on the charging device 30, and the charging voltage Is applied to the slave unit 10 and used for charging and operation. Therefore, even if the slave unit 10 is miniaturized for carrying by using the charging voltage for the operation of the slave unit 10 as well, Easy operation while charging can be realized with a simple configuration.

  Further, since the charging voltage controlled based on the operation information is applied to the slave unit 10 and used for charging and operation, the conventional charging configuration is used as it is, and the charging voltage for charging and operation is used as the child unit. It can be applied to the machine 10 for charging and operation.

  Furthermore, since the charging voltage is controlled for on / off and applied to the slave unit 10 for charging and operation, the charging signal for charging and operation is applied to the slave unit 10 with a simpler configuration. Charging and operation can be performed.

  Furthermore, when the asynchronous serial communication system illustrated in FIGS. 2A and 2B is used, the operation information is the button code data BC, and the on state of the charging voltage corresponds to “data 1”. In addition, since the on / off state of the charging voltage is controlled based on the operation information so that the off state of the charging voltage corresponds to “data 0”, the charging voltage that accurately reflects the contents of the operation information is stored. By being able to be applied to the machine 10, the child machine 10 can be accurately operated.

  When the asynchronous serial communication method is used, one frame corresponding to operation information is generated from the button code data BC, the frame start code data SC, and the inverted code data RC, and the frame is Since the charging voltage is supplied to the child device 10 as a unit and the corresponding processing is executed in the child device 10 with the frame as a unit, the operation can be performed while charging the child device 10 more accurately.

  On the other hand, when the pulse signal illustrated in FIG. 2C is used, on / off of the charging voltage is controlled so that the pulse signal has the number of pulses PL corresponding to the operation information. Since the corresponding processing is executed based on the number of pulses PL, a charging voltage that accurately reflects the contents of the operation information can be applied to the child device 10, so that the child device 10 can be operated accurately.

  In addition, since the size of the operation button 37 included in the operation unit 35 included in the charging device 30 is larger than the size of the operation button included in the operation unit 16 included in the child device 10, Alternatively, regardless of age or sex, the handset 10 being charged can be operated with a simple operation.

  Further, by using the charging terminal 19 and the charging terminal 31 as well as the charging terminal 20 and the charging terminal 32 that are in electrical and physical contact with each other, each charging terminal 19 originally provided for charging the secondary battery 18, etc. The slave unit 10 that is being charged can be operated with a simple configuration.

(II) First Modification Next, a first modification according to the present application will be described with reference to FIG. FIG. 3 is a block diagram showing a schematic configuration of the charging system according to the first modification, and the same components as those of the charging system S according to the embodiment shown in FIG. It shows. Moreover, in the following description, detailed operation description etc. are abbreviate | omitted about the structural member similar to the charging system S which concerns on embodiment.

  As shown in FIG. 3, the slave unit 40 included in the charging system S <b> 1 according to the first modification is an AC detection unit as an example of an extraction unit instead of the charge detection unit 17 in the slave unit 10 according to the embodiment. 41 is provided. Moreover, the charging device 50 included in the charging system S1 has a configuration in which an AC superimposing unit 51 as an example of an AC signal generating unit and an example of a superimposing unit is added to the charging device 30 according to the embodiment.

  In this configuration, the AC superimposing unit 51 of the charging device 50 generates an AC signal having a waveform corresponding to the content of the operation information to be transmitted from the charging device 50 to the child device 40 and outputs the AC signal to the charging control unit 33. At this time, the CPU 34 controls the AC superimposing unit 51 so as to generate the AC signal corresponding to the content of the operation information corresponding to the operation button 37 or the like operated on the operation unit 35. The AC superimposing unit 51 applies the AC signal to the charging terminal 31 while superimposing the AC signal on the charging voltage.

  Here, more specifically, the AC superimposing unit 51 and the CPU 34 determine whether the AC signal is “present” or “not present” or “high” in frequency for the data “1” or data “0” as the operation information. Alternatively, the operation information is transmitted from the charging device 50 to the slave unit 40 in accordance with a so-called asynchronous serial communication method by corresponding to “low”.

  On the other hand, when the child device 40 is placed on the charging device 50 and the charging voltage on which the AC signal is superimposed is applied via the charging terminal 31 or the like, Only the AC signal is extracted, the content of the operation information is detected based on the extracted AC signal, and is output to the CPU 12 as an example of the processing execution means. Thereby, the subunit | mobile_unit 40 operate | moves according to the content of the said operation information by control of CPU12 based on the said operation information.

  According to the operation of the charging system S1 according to the first modification described above, an AC signal having a waveform corresponding to the operation information is supplied to the slave unit 40 by superimposing it on the charging voltage. Since the process is executed based on the AC signal extracted from the charged voltage, it is possible to charge while avoiding the enlargement of the device and the like only by adding the minimum configuration to the conventional charging configuration. And the charge signal for operation can be supplied to the subunit | mobile_unit 40, and the charge and operation can be performed.

(III) Second Modification Finally, a second modification according to the present application will be described with reference to FIG. FIG. 4 is a block diagram showing a schematic configuration of the charging system according to the second modification, and the same components as those of the charging system S according to the embodiment shown in FIG. It shows. Moreover, in the following description, detailed operation description etc. are abbreviate | omitted about the structural member similar to the charging system S which concerns on embodiment.

  As shown in FIG. 4, the slave unit 60 included in the charging system S <b> 2 according to the second modification is replaced with the charge detection unit 17 in the slave unit 10 according to the embodiment, and the charging included in the slave unit 60. A signal detection unit 61 connected to the terminals 19 and 20 is provided. Moreover, the charging device 70 included in the charging system S2 is replaced with the charging control unit 33 in the charging device 30 according to the embodiment, and the charging control unit 71 connected to the charging terminals 31 and 32 provided in the charging device 70. Is provided.

  In this configuration, the charging control unit 71 of the charging device 70 corresponds to the content of the operation information to be transmitted from the charging device 70 to the slave unit 60, and the polarity (positive or negative) of the charging voltage applied to the charging terminals 31 and 32, respectively. Switch negative. At this time, the CPU 34 controls the charge control unit 71 so that the polarity is switched in accordance with the content of the operation information corresponding to the operation button 37 or the like operated on the operation unit 35. Then, the charging control unit 71 applies the charging voltage whose polarity is controlled to the charging terminals 31 and 32, respectively.

  Here, more specifically, the charging control unit 71 and the CPU 34 set the charging voltage applied to the charging terminal 31 to “positive” as the polarity corresponding to the data “1” as the operation information, for example, and apply the charging voltage to the charging terminal 32. The charging voltage is set to “negative”, the charging voltage applied to the charging terminal 31 as the polarity corresponding to the data “0” as the operation information is set to “negative”, and the charging voltage applied to the charging terminal 32 is set to “positive”. The charging voltage is applied to the charging terminals 31 and 32. Note that the relationship between the data “1” and “0” and the polarity of the charging voltage may be opposite to that described above.

  Thereby, when the subunit | mobile_unit 60 is mounted on the charging device 70 and the charging voltage by which the said polarity was controlled is applied via the charging terminal 31 grade | etc., The secondary battery 18 of the subunit | mobile_unit 60 will be the charging terminal. The charging voltage applied to 19 and the charging voltage applied to the charging terminal 20 are added (in other words, their “OR” is taken) to charge themselves.

  On the other hand, the signal detection unit 61 of the child device 60 detects the polarity of the charging voltage applied to the charging terminals 19 and 20, detects the content of the operation information based on the change, and outputs the detected information to the CPU 12. Thereby, the subunit | mobile_unit 40 operate | moves according to the content of the said operation information by control of CPU12 based on the said operation information.

  According to the operation of the charging system S2 according to the second modification described above, the polarity in the charging voltage is switched in accordance with the operation information and supplied to the slave unit 60. In the slave unit 60, the supplied charging is performed. Since the processing is performed based on the change in polarity in voltage, charging for operation and charging is performed while only adding a minimum configuration to the conventional configuration for charging and avoiding an increase in the size of the device. A voltage can be supplied to the handset 60 to charge and operate it.

  In addition, in embodiment and each modification which have been described above, the charging terminals 19 and 20 such as the child device 10 and the charging terminals 31 and 32 such as the charging device 30 are in physical contact with each other to perform charging. Although the case where a voltage is applied to the child device 10 or the like has been described, the present application can also be applied to a charging system including a so-called non-contact type charging device using an electromagnetic induction phenomenon as a principle. In this case, for example, by modulating the charging voltage for non-contact charging by the method according to the above-described embodiment or each modification, operation information is transmitted from the charging device to the slave unit similarly to the embodiment or each modification. can do.

  Further, in the above-described embodiments and modifications, the present application is applied to the charging system S including the charging device 30 and the like for charging the secondary battery 18 in the handset 10 and the like constituting the parent / child phone.
