Description

  The present invention relates to an electronic device reset system, an electronic device reset method, an electronic device, and a reset device that reset an operation of the electronic device using a reset device.

  In recent years, various electronic devices have spread with the progress of computerization. In general, an electronic device is operated by a built-in microcomputer executing a predetermined program. At that time, there are rare cases where the operation becomes unstable or so-called freeze, and in order to recover the operation of the electronic device from such a state, there are many electronic devices in which a reset function is provided in the microcomputer. Such a reset function, for example, when the operator operates a reset switch provided in the electronic device, a reset signal is input to the reset terminal of the microcomputer, thereby forcibly returning the electronic device to the initial state, The obstacles as described above can be removed. Some electronic devices are reset by hardware by temporarily shutting off the power of the electronic device.

  5A and 5B are diagrams illustrating an example of a general electronic device having a reset function, where FIG. 5A is an external perspective view, and FIG. 5B is a configuration block diagram.

  For example, as shown in FIG. 5, a general electronic device having a reset function is provided with a switch 211 that can be operated from the outside so as to be able to be operated from the outside, a battery 213, a microcomputer 214, A function unit 215 that performs operations such as display, sound output, and calculation of the electronic device 210 is incorporated.

  In the electronic device 210 configured as described above, when the operator of the electronic device 210 operates the switch 211, a reset signal is output from the switch 211 and input to the reset terminal of the microcomputer 214. Then, the electronic device is forcibly returned to the initial state under the control of the microcomputer 214, and the reset operation is performed.

  In recent years, depending on the type of electronic equipment, miniaturization has been promoted, and very miniaturized electronic equipment such as wearable devices have also appeared. In such a miniaturized electronic device, since there is no space for providing a reset switch, the reset function as described above cannot be added. Further, in an electronic device having a waterproof function, a reset switch cannot be provided in order to maintain the waterproof function.

  Here, a reset request signal is output to the information processing module using a change in brightness between day and night, and the reset signal does not return from the information processing module in response to this reset request signal. In this case, Patent Document 1 discloses a technique for automatically turning off the power supply to the information processing module and resetting the processing.

  Also, when the reset device button is pressed, a radio, optical, magnetic, etc. signal is transmitted from the transmitter of the reset device, and when this signal is received in a non-contact manner by the receiving unit of the thermometer, A technique for resetting the operation mode is disclosed in Patent Document 2.

  In this way, a reset device for resetting the electronic device is provided, and the electronic device is reset without providing a reset switch in the electronic device by transmitting a reset signal from the reset device to the electronic device in a non-contact manner. Will be able to.

  However, in the one disclosed in Patent Document 1, since the optical sensor is always operating, it can be reset anytime, and there is a problem that the electronic device cannot be reset at an arbitrary timing. is there.

  Also, in the one disclosed in Patent Document 2, since the receiving unit is always in operation, when a magnetic signal is used as the reset signal, the reset signal is received if the magnet is accidentally brought close to the receiving unit. Even if a signal other than magnetism is used as the reset signal, the reset signal is received when light or a signal having the same frequency as the reset signal is received from a device other than the reset device. There is a problem that the electronic device is reset at an unnecessary timing.

  The present invention has been made in view of the problems of the prior art as described above, and is capable of avoiding an unintended reset of the electronic device without providing a reset switch in the electronic device, and at a necessary timing.

In this state, when the reset signal is transmitted in a non-contact manner from the transmitting device of the reset device, the receiving device of the electronic device receives the reset signal transmitted from the transmitting device of the reset device and resets the operation of the electronic device. Is performed.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
1A and 1B are diagrams showing a first embodiment of an electronic device reset system according to the present invention. FIG. 1A is an external view showing the overall configuration, and FIG. 1B is a block diagram showing the configuration.

  As shown in FIG. 1, the electronic device reset system in this embodiment includes an electronic device 10 and a reset device 20 that resets the electronic device 10.

  The reset device 20 includes a switch 23, an LED 22, and a TX module 21. The switch 23 serves as a timing determination unit in the present invention, and is a physical switch that can be operated from the outside of the reset device 20 and is operated when resetting the operation of the electronic device 10. The LED 22 serves as a transmitting means in the present invention, and transmits LED light as a reset signal by turning on when the switch 23 is operated. The TX module 21 serves as a power supply unit in the present invention, and supplies power to the electronic device 10 in a contactless manner.

  The electronic device 10 includes an RX module 11, a drive unit 12, a charging IC 16, and an illuminance sensor 17. The RX module 11 serves as a power receiving means in the present invention, and receives the power supplied from the TX module 21 of the reset device 20 in a contactless manner. The drive unit 12 operates according to the application of the electronic device 10, and includes a function unit 15, a microcomputer 14, and a battery 13. The function unit 15 performs calculations necessary for the operation of the electronic device 10 in addition to an external interface such as a display, a speaker, and an input button. The microcomputer 14 operates the functional unit 15 according to a predetermined program. The battery 13 serves as a power supply unit for the electronic device 10 to perform operations other than reset, and supplies power to the microcomputer 14 and the function unit 15. The charging IC 16 serves as a charging means in the present invention, and charges the battery 13 with the power received by the RX module 11. The illuminance sensor 17 serves as a receiving means in the present invention, and is separated from the battery 13. The illuminance sensor 17 is operated by the electric power received by the RX module 11, and when the reset signal is received by receiving the LED light generated by the lighting of the LED 22 of the reset device 20 in the operation state, the operation of the electronic device 10 is performed. A reset signal for resetting is output to the microcomputer 14.

  Below, the method to reset operation | movement of the electronic device 10 by the reset apparatus 20 in the electronic device reset system comprised as mentioned above is demonstrated.

  FIG. 2 is a flowchart for explaining a method of resetting the operation of the electronic device 10 by the reset device 20 in the electronic device reset system shown in FIG.

  When the operation of the electronic device 10 is reset by the reset device 20 in the electronic device reset system shown in FIG. 1, first, the power supplied from the TX module 21 of the reset device 20 is received by the RX module 11 of the electronic device 10. The reset device 20 is installed in a region where the illuminance sensor 17 of the electronic device 10 can receive the LED light when the LED 22 of the reset device 20 is lit within a possible range. When the reset device 20 is connected to the power source in this state, power is supplied from the TX module 21 of the reset device 20 (step 1).

  Then, since the reset device 20 is installed within a range where the power supplied from the TX module 21 can be received by the RX module 11 of the electronic device 10, the power supplied from the TX module 21 of the reset device 20 is electronic. Power is received by the RX module 11 of the device 10 (step 2).

  When the power supplied from the TX module 21 of the reset device 20 is received by the RX module 11 of the electronic device 10, the power received by the RX module 11 is supplied to the illuminance sensor 17 and the illuminance sensor 17 is activated. (Step 3). The power received by the RX module 11 is also supplied to the charging IC 16 and the battery 13 is charged by the charging IC 16 (step 4). Thus, when the electronic device 10 has the charging IC 16 that charges the battery 13 for performing an operation other than reset, the charging IC 16 charges the battery 13 with the power received by the RX module 11. The battery 13 can be charged using power for operating the illuminance sensor 17 that receives the reset signal from the reset device 20.

  When the switch 23 of the reset device 20 is operated in order to reset the operation of the electronic device 10 in the state where the illuminance sensor 17 is operating with the electric power supplied from the TX module 21 of the reset device 20 as described above. (Step 5), the LED 22 is lit, and the lit LED light is transmitted in a non-contact manner as a reset signal (Step 6).

  When the LED 22 is lit, the reset device 20 is installed in an area where the illuminance sensor 17 of the electronic device 10 can receive the LED light due to the lighting of the LED 22. As a result, the illuminance sensor 17 receives a reset signal when the LED 22 is turned on (step 7). Since the LED 22 is lit with LED light having a wavelength corresponding to the illuminance sensor 17, the illuminance sensor 17 recognizes the reset signal transmitted from the LED 22 by the LED light by receiving the LED light. Can do.

  Then, the illuminance sensor 17 generates a reset signal for resetting the operation of the electronic device 10 and outputs it to the microcomputer 14 (step 8). Then, when the reset signal output from the illuminance sensor 17 is input to the microcomputer 14, the operation of the electronic device 10 is reset under the control of the microcomputer 14 (step 9). For example, when the microcomputer 14 resets the operation of the electronic device 10 when a high-level potential is applied to a reset port provided in the microcomputer 14, the illuminance sensor 17 turns on the LED light by turning on the LED 22. Is received as a reset signal to the microcomputer 17. When this high-level potential reset signal is applied to the reset port of the microcomputer 14, the microcomputer 14 controls the microcomputer 17. The operation of the electronic device 10 is reset.

  As described above, when the switch 23 provided in the reset device 20 is operated, the LED 22 is lit, and when the illuminance sensor 17 receives the LED light resulting from the lighting, the illuminance sensor 17 transmits the light to the microcomputer 14. Since the operation of the electronic device 10 is reset by outputting a reset signal, the electronic device 10 can be reset without providing a reset switch in the electronic device 10, thereby reducing the size and waterproofing function of the electronic device 10. Can be realized. Further, in such a configuration, the illuminance sensor 17 operates for the first time when the power supplied from the TX module 21 of the reset device 20 is received by the RX module 11 and the received power is supplied. In the operating state, when the LED light due to the lighting of the LED 22 is received from the reset device 20, the operation of the electronic device 10 is reset by outputting a reset signal to the microcomputer 14. Even when light having the same wavelength is received from a device other than the reset device 20, an unintended reset of the electronic device 10 can be avoided, and the electronic device 10 can be reset at a necessary timing.

  In this embodiment, power is supplied from the TX module 21 of the reset device 20 to the electronic device 10 in a contactless manner, and the power supplied from the TX module 21 is received in a contactless manner by the RX module 11 of the electronic device 10. Therefore, there is no need to connect the electronic device 10 and the reset device 20 with a cable or the like.

(Second Embodiment)
3A and 3B are diagrams showing a second embodiment of the electronic device reset system of the present invention. FIG. 3A is an external view showing the overall configuration, and FIG. 3B is a block diagram of the configuration.

  As shown in FIG. 3, the electronic device reset system in this embodiment includes an electronic device 110 and a reset device 120 that resets the electronic device 110.

  The reset device 120 includes a switch 123, a Hall IC 122, and a connection terminal 121. The switch 123 serves as a timing determination means in the present invention, and is a physical switch that can be operated from the outside of the reset device 120 and is operated when resetting the operation of the electronic device 110. The Hall IC 122 serves as a transmission means in the present invention, and generates a magnetism when the switch 123 is operated, thereby transmitting a magnetic signal as a reset signal in a non-contact manner. The connection terminal 121 serves as a power supply unit in the present invention, and is configured to be connectable with a cable, and supplies power to the electronic device 110 via the connected cable.

  The electronic device 110 includes a connection terminal 111, a drive unit 112, and a magnetic sensor 117. The connection terminal 111 serves as a power receiving means in the present invention, and is configured to be connectable to a cable, and receives power supplied from the connection terminal 121 of the reset device 120 via the connected cable. The drive unit 112 operates in accordance with the application of the electronic device 110, and includes a function unit 115, a microcomputer 114, a battery 113, and a power cutoff circuit 116. The function unit 115 performs calculations necessary for the operation of the electronic device 110 in addition to an external interface such as a display, a speaker, and an input button. The microcomputer 114 operates the functional unit 115 according to a predetermined program. The battery 113 supplies power to the microcomputer 114 and the function unit 115. The power cut-off circuit 116 is connected between the battery 113 and the microcomputer 114, and cuts off power supply from the battery 113 to the microcomputer 114 by a power cut-off signal. The magnetic sensor 117 serves as a receiving means in the present invention, and is separated from the battery 113. When the magnetic sensor 117 operates by the power received at the connection terminal 111 and receives a magnetic signal serving as a reset signal by detecting magnetism generated in the Hall IC 122 in the operation state, the magnetic sensor 117 In order to reset the operation, a power cut-off signal for cutting off the supply of power from the battery 113 to the microcomputer 114 is output to the power cut-off circuit 116.

  Hereinafter, a method of resetting the operation of the electronic device 110 by the reset device 120 in the electronic device reset system configured as described above will be described.

  FIG. 4 is a flowchart for explaining a method of resetting the operation of electronic device 110 by reset device 120 in the electronic device reset system shown in FIG.

  When resetting the operation of the electronic device 110 by the reset device 120 in the electronic device reset system shown in FIG. 3, first, when magnetism is generated in the Hall IC 122 of the reset device 120, the magnetism is detected by the magnetic sensor of the electronic device 110. The reset device 120 is installed within a range that can be detected by 117, and the connection terminal 111 of the electronic device 110 and the connection terminal 121 of the reset device 120 are connected via a cable. When the reset device 120 is connected to the power supply in this state, power is supplied from the connection terminal 121 of the reset device 120 to the electronic device 110 via the cable (step 101).

  The power supplied from the connection terminal 121 of the reset device 120 to the electronic device 110 via the cable is received by the connection terminal 111 of the electronic device 110 (step 102).

  When the power supplied from the connection terminal 121 of the reset device 120 is received by the connection terminal 111 of the electronic device 110 via the cable, the power received by the connection terminal 111 is supplied to the magnetic sensor 117, and the magnetic sensor 117 is activated (step 103).

  When the switch 123 of the reset device 120 is operated in order to reset the operation of the electronic device 110 in a state where the magnetic sensor 117 is operating with the electric power supplied from the reset device 120 as described above (step 104). Then, magnetism is generated in the Hall IC 122, and the magnetic signal is transmitted as a reset signal in a non-contact manner (Step 105).

  When magnetism is generated in the Hall IC 122, the reset device 120 is installed within a range in which the magnetic sensor 117 of the electronic device 110 can detect the magnetism generated in the Hall IC 122. A magnetic signal that is detected by the magnetic sensor 117 of the device 110 and becomes a reset signal due to magnetism generated in the Hall IC 122 is received by the magnetic sensor 117 (step 106).

  Then, the magnetic sensor 117 generates a power cutoff signal for shutting off the power source of the microcomputer 114 in order to reset the operation of the electronic device 110, and outputs it to the power cutoff circuit 116 (step 107). Then, the power cut-off signal output from the magnetic sensor 117 is input to the power cut-off circuit 116, whereby the supply of power from the battery 113 to the microcomputer 114 is cut off. The operation of the device 10 is reset (steps 108 and 109). As the power cutoff circuit 116, for example, a switching circuit such as a transistor can be considered. In this case, when magnetism is detected by the magnetic sensor 117, a high level signal is output to the power cutoff circuit 116, and the switching of the power cutoff circuit 116 is performed. When the circuit is turned off by the high level signal, the supply of power from the battery 113 to the microcomputer 114 is cut off, and the operation of the microcomputer 114 is stopped.

  As described above, when the switch 123 provided in the reset device 120 is operated, magnetism is generated in the Hall IC 122, and when this magnetism is detected by the magnetic sensor 117, the power shutoff circuit 116 is connected from the magnetic sensor 117. On the other hand, since the operation of the electronic device 110 is reset by outputting a power-off signal for cutting off the supply of power from the battery 113 to the microcomputer 114, the electronic device 110 is not provided with a reset switch. Can be reset, whereby the electronic device 110 can be downsized and provided with a waterproof function. In such a configuration, the magnetic sensor 117 operates for the first time when power received at the connection terminal 111 of the electronic device 110 is supplied via the cable connected to the connection terminal 121 of the reset device 120. When the magnetism generated in the Hall IC 122 of the reset device 120 is detected by the magnetic sensor 117 in the operation state, the operation of the electronic device 110 is reset by outputting a power cutoff signal to the power cutoff circuit 116. Therefore, even if the magnet is brought close by mistake, an unintended reset of the electronic device 110 can be avoided, and the electronic device 110 can be reset at a necessary timing.

  In the above-described embodiment, when the switches 23 and 123 provided in the reset devices 20 and 120 are operated, the LED 22 is turned on or magnetism is generated in the Hall IC 122, so that the electronic device A reset signal for resetting the operation of 10, 110 is generated, but when a predetermined signal is input to the reset devices 20, 120 or a predetermined condition is satisfied, a reset signal is generated, A reset signal may be generated at a predetermined timing.

  Moreover, in embodiment mentioned above, electric power is supplied to the electronic devices 10 and 110 from the reset apparatus 20 and 120, the illumination intensity sensor 17 and the magnetic sensor 117 of the electronic devices 10 and 110 are operated by this electric power, When the switches 23 and 123 are operated in the state, a reset signal for resetting the operation of the electronic devices 10 and 110 is generated by turning on the LED 22 or generating magnetism in the Hall IC 122. However, when the switches 23 and 123 are operated, power is supplied from the reset devices 20 and 120 to the electronic devices 10 and 110 to operate the illuminance sensor 17 and the magnetic sensor 117, and the LED 22 is lit or the Hall IC 122 is turned on. The operation of the electronic devices 10 and 110 is reset by generating magnetism. It may be configured to generate a reset signal for.
