Prior to the description, the key technical gist of the present invention is to irradiate a constant light on a compass divided into a bright part and a dark part, measure the intensity of the reflected optical signal, and control the power supply accordingly. The object of the present invention will be easily achieved.

1 is a block diagram of a power control apparatus using a compass according to a preferred embodiment of the present invention, the power supply unit 100, the mode switch 102, the load 104, the reflected light sensor 106, the compass 108 ), The relay 110 and the controller 10.

In addition, FIG. 2 is a configuration diagram illustrating an example in which the power control device of FIG. 1 is applied to a laser pointer, and includes a reflected light sensor 200, a relay 201, a circuit board 202, and a bright part of a compass ( 203, a dark portion 204 of the compass, an optical sensor rotation axis 205, a mode changeover switch 206, a laser pointer body 207, and a light emitting device 208, respectively.

Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 1 and 2.

As shown in FIG. 1, the power supply unit 100 is a means for supplying power to the load 104. The power supply unit 100 has the same function as a power supply unit included in a general power control device, and thus a detailed description thereof is omitted. Let's do it.

The mode changeover switch 102 applied to the present invention is used as a means for outputting a switching signal for determining whether to control power according to a direction. That is, the mode switching switch 102 outputs a mode selection key signal for selecting the power control mode or the general power supply mode. As described in detail in the flowchart below, if the power control mode, the mode changeover switch 102 is switched to the reflected light sensor 106 side, so that the power supplied from the power supply unit 100 is provided to the reflected light sensor 106. In the normal power supply mode, the mode changeover switch 102 is switched to the load 104 such that the power supplied from the power supply 100 is provided to the load 104.

The reflected light sensor 106 irradiates a predetermined light, for example, infrared light, generated from the light emitting device 208 with the compass 108, measures the intensity of the light reflected from the compass 108, and detects a detection signal corresponding to the measured light intensity. Performs a function provided to the controller 10 to be described later. That is, the reflected light sensor 200, as shown in FIG. 2, when the optical signal irradiated from the reflected light sensor 200 is reflected through the bright portion 203 of the compass to provide the detection signal according to the control unit 10 and When the optical signal emitted from the reflected light sensor 200 is reflected through the dark portion 204 of the compass, the detection signal corresponding thereto is provided to the controller 10.

The reflective optical sensor 200 is implemented to rotate around the optical sensor rotation axis 205, so that the user can directly adjust the on / off direction of the optical sensor 200.

When the control unit 10 according to the present invention is set to the power control mode by the switching operation of the mode switching switches 102 and 206, when power is supplied to the reflected light sensors 106 and 200, the reflected light sensor ( The power supply paths of the mode changeover switches 102 and 206 are controlled by turning on / off the relays 110 and 201 according to the measurement data according to the intensity of the optical signal provided from the 106 and 200. do.

That is, the compass 108 used in the present invention is divided into a bright portion 203 and a dark portion 204, the light portion of the compass 108 is always directed only a certain direction, so the reflected light sensor 106 Power is turned on only when the position of, 200 is in a certain direction. In this case, in order for the user to select a direction in which the power is turned on, the reflective light sensor 200 may be rotated in a desired direction about the optical sensor rotation axis 205.

Therefore, when the present invention is applied to the laser pointer 207 shown in FIG. 2 using the principle of the compass 108, the direction in which the laser pointer 207 is instructed is turned on by rotating the reflected light sensor 200. FIG. In this case, since the reflected light sensor 200 detects the dark portion 204 of the compass at the position where the laser should not be output, the power is automatically turned off by the relay 201 to output the laser light source from the laser light emitting device 208. It doesn't work.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figure 3 attached to the power control process using a compass according to the present invention will be described in detail.

First, in step S300, the power control direction is set. As described above, the power control direction setting may be implemented by rotating the positions of the reflection light sensors 106 and 200 about the rotation axis 205.

When the power control direction is set, the process proceeds to step S302 to allow power to be supplied to the power control device through the power supply unit 100.

Subsequently, in step S304, it is determined whether the current mode is the power control mode or the general power supply mode by the switching operation of the mode switching switches 102 and 206. That is, it is determined whether or not the power control function according to the direction is used.

If it is determined in step S304 that the normal power supply mode, the flow advances to step S306 to switch the mode switching switches 102 and 206 to the load 104 side so that power is supplied to the load 104.

If it is determined in step S304 that the power control mode, the flow advances to step S308 to switch the mode switch (102, 206) so that power is supplied to the reflected light sensor (106), (200).

When power is supplied to the reflected light sensors 106 and 200, a predetermined optical signal, for example, infrared light, is emitted through the reflected light sensors 106 and 200. The optical signal is irradiated to the compass 108, and the optical signal irradiated to the bright portion 203 or the dark portion 204 of the compass is reflected back to the reflected light sensor 106,200.

The reflected light sensors 106 and 200 provide a detection signal corresponding to the input optical signal to the controller 10.

In this case, in step S310, the controller 10 determines whether the detection signal, that is, the optical signal reflected by the compass 108 is greater than or equal to a certain intensity. This criterion is based on a reflected signal that changes depending on whether an optical signal is irradiated to the bright portion 203 of the compass or an optical signal is irradiated to the dark portion 204 of the compass.

As a result of the determination in step S310, if the optical signal reflected by the compass 108 is less than or equal to a certain intensity, that is, the optical signal is irradiated to the dark portion 204 of the compass and reflected back to the reflected optical sensors 106 and 200. When the signal is received as a signal of less than the reference value, the control unit 10 proceeds to step S316 to turn off the relays 110 and 201.

Therefore, in step S318, the power supply to the load 104 is cut off.

On the other hand, as a result of the determination in step S310, if the optical signal reflected through the compass 108 is more than a certain intensity, that is, the optical signal is irradiated to the bright portion 203 of the compass, the reflected light sensor 106, 200 When the reflected signal is received as a signal higher than or equal to the reference value, the controller 10 proceeds to step S312 to turn on the relays 110 and 201.

Therefore, in step S314, power supply to the load 104 is formed.

As mentioned above, although this invention was demonstrated concretely based on an Example, this invention is not limited to this Example, The range of a power supply control technique applied to various modifications, for example, a laser pointer, is not limited to the range which does not deviate from the summary. It is possible to apply a technique to prevent the gun from triggering if it is applied to the gun of a certain off target.

Therefore, the present invention can facilitate the on / off control of the power supply using the operation principle of a simple compass, it is possible to implement a power control technology having a structurally simple and excellent performance. In addition, the present invention can be applied to a laser pointer to create an excellent effect. That is, the laser pointer may cause a fatal damage to the human eye, but when the laser source is directed in the human direction due to the application of the present invention, the laser pointer is automatically turned off to prevent a safety accident in advance. will be. In addition, the present invention is not limited to such a laser pointer, and applied to the field in which other light sources are used, for example, a gun in a shooting range, so that the gun is not triggered when the muzzle does not face the target, thereby preventing a safety accident. It works.
