Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual configuration diagram of a laser generator driving apparatus according to the present invention,

As shown in the drawings, the laser generator driving apparatus of the present invention includes a footrest 10, a plurality of transmitters 21 arranged on the side edge of the footrest, and various switches S1 to S4 provided on the top surface of the footrest. It can be seen that the transmitter 20, including a receiver 30 mounted below the laser generator.

The footrest 10 is a plate for the user to step on the foot as the name, and is a medium on which the transmitter 20 is mounted. The shape of the scaffold 10 may be any shape, and only has a side edge where the transmitter 21 may be installed in all directions horizontal to the ground, and a predetermined area on which various switches S1 to S4 may be installed. It should have a flat top surface.

The transmitter 20 is shown in Figure 1 and Figure 2 showing a block diagram,

As the transmitter 21, various switches S1 to S4, and the transmitter signal processor, the code generator 22, the key encoder 24, the carrier generator 23, the ID setup unit 28, and the battery 26 It is configured to include a power supply control unit 25 and the charging unit 27.

The transmitter 21 is a component that transmits a wireless signal to the receiver 30, and may be an infrared LED or a wireless FM transmitter that emits an FM signal as the light emitting device 21 that emits an optical signal as shown in the drawing.

The transmitter 21 transmits a signal in all directions (ie, all directions parallel to the ground).

In the case of a light emitting device, a plurality of light emitting devices are mounted and arranged at regular intervals on the entire side edge of the scaffold 10,

In the case of the FM transmission element, omnidirectional transmission is possible with only one, so it is mounted on a predetermined portion of the scaffold.

The switches S1 to S4 are for generating command signals for operating the laser generator 1 by the user's foot.

An on-off switch S1 for turning on or off the laser irradiation of the laser generator 1,

Intensity control switch (S2) for stepwise adjusting the energy intensity (that is, the magnitude of the amplitude of the laser pulse) to be irradiated,

A pulse control switch S3 for gradually adjusting the pulse rate of the irradiated laser (that is, the output frequency of the laser),

It comprises a peripheral device switch (S4) and the like to turn on or off the peripheral devices required during the procedure using the laser generator (1).

Representative of the peripheral device is a refrigerant supply pump such as a water pump or an air pump, the peripheral switch is a refrigerant switch (S4) for turning on and off the operation of the refrigerant supply pump.

Since the on-off switch S1 or the refrigerant switch S4 issues only an on or off command, a switch in the form of a button or a switch in the form of flipping up or down is usually employed.

The intensity control switch (S2) or the pulse control switch (S3) is to adjust the energy size and pulse rate of the laser to be irradiated step by step, like a wheel of the mouse to push the switch up or down, or pushes up or down Lever type switch is adopted. In addition, the laser generator 1 should be provided with a display screen so that the user can recognize the energy size or pulse rate of the laser irradiated by the manipulation of the intensity control switch S2 or the pulse control switch S3.

The transmission signal processor includes a key encoder 24, a code generator 22, and a carrier generator 23.

The key encoder 24 processes the various command signals transmitted from the various switches S1 to S4 so as to be processed by the receiver 30, converts them into 4-bit data signals, and sets them in the ID setting unit 28. The unique ID of 4 bits is read, and the unique ID is added to the processed command signal to transmit a total of 8 bit data signals to the code generator 22.

The carrier generator 23 generates a frequency (carrier) of a predetermined band through which the transmitter 20 and the receiver 30 can wirelessly communicate with each other.

The code generator 22 outputs the data signal transmitted from the key encoder 24 to the transmitter 21 by placing (overlapping) the frequency signal (carrier) generated by the carrier generator 23 (e.g., 38 kHz). In this way, the transmitter 21 is operated to cause the transmitter 21 to emit a radio command signal.

In addition, a battery 26 for supplying power to each component of the transmitter 20, and a charging unit 27 for charging the battery 26 is further provided.

The power of the battery 26 is transmitted to each component of the transmitter 20 through the power supply control unit 25.

The power supply control unit 25 is interlocked with the on-off switch S1 so that the power of the battery 26 is supplied to other components at the moment when the on-off switch S1 is turned on.

The power supply control unit 25 cuts off the power supply of the battery 26 when the on state of the on-off switch S1 lasts for a predetermined time (5 minutes).

When the on-off switch S1 is in the OFF state (i.e., the state in which the laser irradiation is not performed) for a long time, the user only turns off the power of the laser generator 1 after the procedure is finished or the user performs another operation. Since it will be left unattended, in this case, the power supply control unit cuts off the power supply of the battery in order to prevent unnecessary power consumption of the battery 26.

The receiver 30 receives the radio command signal from the transmitter 20, processes it, converts it into an operation signal for operating the laser generator 1, and outputs the signal to the control unit 2 of the laser generator. Then, the control unit 2 of the laser generator outputs a laser having a predetermined energy and pulse rate by the transmitted operation signal.

As shown in FIG. 1, the receiver 30 is mounted on the lower part of the laser generator 1 so that the wireless communication is performed smoothly so as to align the horizontal position with the scaffold 10 and the light emitted by the transmitter 21 of the transmitter 20. The signal is received either directly or after reflecting off the floor.

The receiver 30 has a receiver 31, a carrier detector 32, a key decoder 34, and an ID setter 38 as shown in FIG. 1 and a block diagram of FIG. Is made of.

The receiver 31 is a component for receiving a command signal issued by the transmitter 21 of the transmitter 20. If the transmitter 21 is an infrared LED that is a light emitting device, a plurality of light receivers are arranged in a horizontal direction with respect to the ground. Element, and if the transmitter 21 is a wireless FM transmitter, it will be a wireless FM receiver.

The carrier detector 32 detects the frequency of the signal transmitted from the receiver 31. That is, the carrier frequency is removed to restore an 8-bit data signal combined with a 4-bit unique ID and a 4-bit command signal.

The key decoder 34 reads the ID preset in the ID setting section 38, compares the read ID with the unique ID of the signal transmitted from the carrier detection section 32,

If they do not coincide with each other, the command signal transmitted from the carrier detector 32 is bypassed and no further operation is performed.

If they coincide with each other, the command signal transmitted from the carrier detector 32 is processed into a signal conforming to the laser generator and the interface communication protocol, converted into an operation signal, and then output to the control unit 2 of the laser generator. Then, the controller 2 drives the laser generator 1 according to the transmitted operating signal.

As described above, the transmitter 20 and the receiver 30 wirelessly transmit and receive the ID to prevent the laser generator from malfunctioning due to electrical interference with other electronic devices around.

As described above, the present invention wirelessly transmits and receives a signal between a receiver and a transmitter, so that the user's convenience is enhanced because there is no restriction in the movement of the scaffold or the laser generator.

Since transmitters and receivers transmit and receive signals in all directions, there is no risk of interrupting the transmission of signals during wireless communications.

Including unique ID, that is, one-to-one correspondence of scaffolding (transmitter) and laser generator (receiver), very useful for industrial development without the risk of interference with other electronic devices around in the process of transmitting and receiving signals in all directions It is a laser generator driving device.
