The operation part of the switch can also be a push button type. In addition, the power storage section of the switch can also store power when the operation section is pressed or released.

In this configuration, the acceleration of the push-button switch can be used to easily store power in the power storage unit.

The display portion of the switch may be electronic paper.

In this configuration, no power is required to maintain the displayed information, and power consumption can be suppressed.
[Effect of the invention]

According to the present invention, the power generated by the self-generating device can be used to transmit and receive control information, and to maintain the display of the transmission and reception results.

Hereinafter, the form for implementing this invention is demonstrated with reference to drawings.

• Application Example First, an example in which the present invention is applied will be described using FIG. 1. FIG. 1 is a block diagram of a switch 10 according to a first embodiment of the present invention. The switch is, for example, a push-button wireless switch and performs wireless communication. In the following embodiments, as a specific example of the control, a push-button wireless switch is used to indicate, but it can also be applied to control of other operation switches.

The switch 10 includes an operation section 110, a power supply section 120, and an execution circuit section 130. The power supply unit 120 includes a power generation unit 121, a rectification unit 122, a power storage unit 123, a stabilization unit 124, and a voltage monitoring unit 125. The execution circuit unit 130 includes a shutdown control unit 131, a control unit 132, a transmission / reception unit 133, and a display unit 134. The transmitting / receiving unit 133 is a communication unit of the present invention.

The user presses the operation section 110. Thereby, a part of the operation section 110 acts on the power generation section 121, and the power generation section 121 generates power. As a result, the voltage monitoring unit 125 determines that the operation unit 110 has been pressed. Although not particularly shown, the operation section 110 includes an acceleration generating section. The acceleration generating unit is configured to generate an acceleration for accelerating the moving speed of the power generation shaft by using an elastic force or the like for the operation of the operation unit 110. At this time, the acceleration is given to the power generation section 121. Thereby, effective power generation can be realized as shown below.

The power generation unit 121 outputs power obtained by power generation to the rectification unit 122. Although not particularly shown, the power generation section 121 includes a power generation shaft that is moved in a direction to be operated by operating the operation section 110, and an electromagnetic induction member formed with a through hole into which the power generation shaft is partially inserted. . When the operation unit 110 is operated, the power generation shaft is moved in the direction of being inserted into the through hole of the electromagnetic induction member. The power generation unit 121 generates electromotive force by moving the power generation shaft in the through hole, that is, by changing the amount of insertion of the power generation axial through hole. More specifically, the power generation unit 121 is a person who uses electromagnetic induction and changes the power generation amount according to the movement speed of the power generation shaft. The faster the movement speed, the larger the power generation amount.

The rectifying section 122 rectifies AC power into DC power. The rectifying section 122 outputs the rectified DC power to the power storage section 123.

The power storage unit 123 stores DC power. In addition, the power storage unit 123 outputs power required for the transmission of the control signal and the result display to the stabilization unit 124.

The stabilization unit 124 supplies power to the execution circuit unit 130. The stabilization unit 124 is, for example, a MOS-FET. The stabilization unit 124 is connected to the cutoff control unit 131. The cut-off control unit 131 controls the supply of electric power to the control unit 132, the transmission / reception unit 133, and the display unit 134.

The control unit 132 outputs a control signal to the transmission / reception unit 133. The control unit 132 performs display control of the display unit 134. More specifically, the control unit 132 performs control related to the display of the transmission / reception results and the like of the display unit 134 and the clearing of the display.

The transmitting and receiving unit 133 transmits the control signal and the SYN packet to the receiver 20 to which the control target device is connected. The transmission / reception unit 133 receives the SYN + ACK packet from the control target device via the receiver 20 as a transmission / reception result. The transmission / reception unit 133 outputs the transmission / reception result to the control unit 132.

The control unit 132 outputs a transmission / reception result to the display unit 134. The display unit 134 is a display state maintaining type display device. The display unit 134 displays the transmission / reception result, and displays the transmission / reception result until the next time (when re-operating) the operation unit 110 is pressed.

The display unit 134 is, for example, a liquid crystal electronic paper, and can display the transmission and reception results by changing the display, color, and the like. For example, when the transmission / reception result is normal, it becomes colored, and when the transmission / reception result is abnormal, it becomes colorless.

Next, the user releases the state in which the operation unit 110 is pressed. As a result, a part of the operation section 110 acts in a direction opposite to that when pressed, and the power generation section 121 generates power. As a result, the voltage monitoring unit 125 determines that the operation unit 110 is released. At this time, power generation is also efficiently performed by generating acceleration.

The power generation unit 121 outputs negative power obtained by power generation to the rectification unit 122.

The rectifying section 122 rectifies the AC power so that it becomes the required DC power. The rectifying section 122 outputs the rectified DC power to the power storage section 123. The power storage unit 123 stores DC power.

That is, in order to transmit the control signal, the power generated by operating the operation section 110 can be used for the transmission of the control signal and the display of the transmission and reception results of the control signal, and the display status of the transmission and reception results can be maintained. In addition, the transmission of control signals and the display of the results of transmission and reception of control signals do not require other power sources, which can reduce costs.

In addition, the electric power at the time of the pressing operation of the operation section 110 and the release operation of the operation section 110 can be stored in the power storage section 123, and electric power can be stored more efficiently.

In addition, since the display portion 134 is electronic paper, in order to maintain the display, power is not required, and thus a power saving effect can be obtained.

• Composition example 1
FIG. 1 is a block diagram of a switch 10 according to a first embodiment of the present invention. Fig. 2 is a schematic diagram of a switch according to the first embodiment of the present invention. 3 is a waveform diagram of an output voltage when the switch of the first embodiment of the present invention is pressed and released. Fig. 4 is a flowchart showing control of a switch according to the first embodiment of the present invention.

Based on the configuration of the switch 10 in FIG. 1 described above, a more specific configuration example will be described with reference to FIG. 2.

As shown in FIG. 2, the switch 10 includes a case 115. The housing 115 includes an operation section 110 and a display section 134.

As shown in FIGS. 1 and 2, a receiver 20 connected to a PLC or the like as a control target device performs control by receiving a signal transmitted from the transmitting and receiving unit 133. In addition, the receiver 20 transmits and receives the result to the transmission / reception unit 133.

More specifically, the transceiver unit 133 sends the control signal and the SYN packet to the receiver 20. The receiver 20 receives the control signal and sends a SYN + ACK packet to the transceiver unit 133. The transceiver unit 133 receives the SYN + ACK packet and confirms that the control signal has been delivered to the receiver 20.

The transmission / reception unit 133 outputs a transmission / reception result to the control unit 132. The control unit 132 outputs the transmission / reception result to the display unit 134. The display unit 134 is a display device of a display state maintaining type.

The display unit 134 displays the transmission and reception results. In addition, the display, color, and the like of the display unit 134 are changed according to the transmission and reception results. As described above, for example, when the transmission / reception result is normal, it becomes colored, and when the transmission / reception result is abnormal, it becomes colorless.

The display unit 134 may be an electrophoretic electronic paper or a dot matrix (TFT) electronic paper. In this case, it is also possible to display the result of sending and receiving or a statement indicating a control signal.

FIG. 3 is an example of waveform diagrams of output voltages when the operation section 110 is pressed and when the operation section 110 is released. The left side of FIG. 3 is when the operation part 110 is pressed, and the right side of FIG. 3 is when the operation part 110 is released.

As shown in FIG. 3, a positive voltage is output when the operation part 110 is pressed, and a negative voltage is output when the operation part 110 is released. Based on this, the operation of pressing the operation section 110 and the operation of releasing the operation section 110 can be judged. When the operation unit 110 is pressed, a threshold value may be set in advance. When the operation unit 110 is exceeded, it is determined that the operation unit 110 is pressed.

The control of the switch according to the first embodiment of the present invention will be described using the flowchart of FIG. 4.

In order to send a control signal, the operation unit 110 itself is pressed. As a result, the power generation unit 121 generates a positive voltage (S101).

As described above, the power generation unit 121 supplies power to the execution circuit unit 130 via the power generation unit 121, the rectification unit 122, the power storage unit 123, and the stabilization unit 124 (S102).

The control unit 132 clears the display of the display unit 134 (S103).

The control unit 132 outputs a control signal to the transceiver unit 133, and the transceiver unit 133 sends the control signal to the receiver 20 (S104).

When the transmission / reception unit 133 can receive the transmission / reception result from the receiver 20 connected to the control target device (S105: Yes), the transmission / reception result is displayed on the display unit 134 (S106).

When the transmission / reception unit 133 cannot receive the transmission / reception result from the receiver 20 connected to the control device (S105: No), the display unit 134 does not perform any display (S116).

The shutdown control section 131 shuts off the power supply section 120 and the execution circuit section 130 (S107). In addition, since the display unit 134 is a display state holding type, the display content can be maintained even if the power supply is stopped.

Next, the operation unit 110 releases the state in which it was pressed. As a result, the operation unit 110 generates a negative voltage (S108).

The operation unit 110 stores power in the power storage unit 123 via the power generation unit 121 and the rectification unit 122 (S109).

That is, the power generated by operating the operation section 110 can be used for the control signal transmission and the control signal transmission and reception result display, and the display state can be maintained. In addition, the transmission of control signals and the display of the results of transmission and reception of control signals do not require other power sources, which can reduce costs. The above is particularly effective for wireless switches that have difficulty in supplying power from the outside.

The display unit 134 can be used to hold the transmission and reception results, and the visibility of the user is improved. In addition, since the display portion 134 is an electronic paper, in order to maintain the display state, power is not required, and thus a power saving effect can be obtained.

• Composition example 2
Next, the outline of the switch of the second embodiment will be described with reference to FIG. 5. Fig. 5 is a flowchart showing the control of the switch 10A according to the second embodiment of the present invention.

In the second embodiment, the execution steps of the control are different from those in the first embodiment. The other points are the same as those of the first embodiment, and descriptions of the same parts will be omitted.

In order to send a control signal, the operation unit 110 itself is pressed. Thereby, the power generation unit 121 generates a positive voltage (S201).

As described above, the power generation unit 121 supplies power to the execution circuit unit 130 via the power generation unit 121, the rectification unit 122, the power storage unit 123, and the stabilization unit 124 (S202).

The control unit 132 outputs a control signal to the transmitting and receiving unit 133, and the transmitting and receiving unit 133 sends the control signal to the receiver 20 (S203).

When the transmission / reception unit 133 cannot receive the transmission / reception result from the receiver 20 (S204: YES), the transmission / reception result is displayed on the display unit 134 (S205). When receiving and sending the result, start the timer. The timer refers to a timer that counts down within a predetermined time. For example, the timer is 180 seconds.

When the transmission / reception unit 133 cannot receive the transmission / reception result from the receiver 20 (S204: No), the display unit 134 does not perform any display (S215).

The shutdown control section 131 shuts off the power supply section 120 and the execution circuit section 130 (S206).

Next, the operation unit 110 releases the state in which it was pressed. As a result, the operation unit 110 generates a negative voltage (S207).

The operation unit 110 stores power in the power storage unit 123 via the power generation unit 121 and the rectification unit 122 (S208).

The display unit 134 updates the display state of the display unit 134 when the countdown timer received in step S204 becomes 0 (S209).

Even with such a configuration, the power generated by operating the operation unit 110 can be used to display control signal transmission and control signal transmission and reception results, and the display state can be maintained. This improves the legibility of the user. In addition, the transmission of control signals and the display of the results of transmission and reception of control signals do not require other power sources, which can reduce costs.

In addition, since the display portion 134 is an electronic paper, in order to maintain the display state, power is not required, and thus a power saving effect can be obtained.

Furthermore, by using a timer to automatically update the display, the user will not make a mistake in the next operation, which improves convenience. Moreover, in the above example, the time information of the timer is set to 180 seconds, but it can also be set to 180 seconds or less, and can be set in accordance with the application of the actual environment.
