Looking at the overall configuration of the present invention, the input current (Io) supplied to the beam projector 100 in the on (On) or off (Off) operating state of the beam projector 100 and the beam projector 100 A control unit 300 that detects and outputs a control signal and automatically turns on in conjunction with an on or off operation of the beam projector 100 by a control signal output from the control unit 300. (On) operation (or also referred to as "installation") or Off (or "off" operation) is made of the auxiliary device 400 is controlled.

The auxiliary device 400 linked to the beam projector 100 includes at least one of an electric screen installed in a conference room, lighting, an electric curtain, and an elevation for a beam projector. It should not be limited to these.

Of course, the beam projector 100 may also be remotely controlled by a remote controller (not shown) using separate IR (Infrared Rays) or RF (Radio Frequency) signals.

First, a first embodiment for solving the problem of the present invention will be described with reference to the accompanying FIG.

A beam projector 100 as described above is provided, and a sensing unit 200 for sensing an input current Io supplied to the beam projector 100 is configured.

The detection unit 200 is made of a current sensor, which may be installed on any one of the power line 110 so that the input current (Io) supplied to the beam projector 100 is detected. .

In addition, the determination unit for determining whether the input current (Io) sensed by the detection unit 200 is at least one of the first control current (I1) and the second control current (I2) set in the setting unit (330) ( 340 is configured.

If the input current Io sensed by the detector 200 is determined by the determination unit 340 as the set first control current I1, then a control signal for turning on the auxiliary device 400 is turned on. Is output to the switching unit 380, and if it is determined by the determination unit 340 by the set second control current I2, then a control signal for turning off the auxiliary device 400 is switched. It characterized in that it comprises a control unit 310 to output to 380.

Here, the control unit 310 is composed of a microcomputer (Micom), the control of the overall operation of the control unit 300 as described above is made.

Next, a second embodiment for solving the problems of the present invention will be described with reference to FIG. 3.

As already mentioned in the first embodiment, if the input current Io sensed by the sensing unit 200 is determined by the determination unit 340 as the set first control current I1, then the auxiliary device 400 Outputs a control signal for turning on, and if it is determined by the determination unit 340 based on the set second control current I2, control for turning off the auxiliary device 400 at this time. The control unit 310 for outputting a signal is configured.

Subsequently, the control signal output from the controller 310 is supplied to the beam projector 100 to at least two or more of the auxiliary devices 400 connected to the auxiliary device 400 on or off. It characterized in that it comprises a signal switching unit 320 for outputting a control signal to the switching unit 380 in the order of operation.

Here, the switching unit 380 is characterized in that it comprises a plurality of switching units (381-384) to be matched (Matching) to each auxiliary device (400).

For example, if the beam projector 100 installed in the conference room is turned on to present the conference data on the electric screen, the beam projector (as shown in FIG. Elevation for the beam projector 100 is mounted first while lowering the beam projector 100 installed on the ceiling, and then sequentially install the electric screen, install the electric curtain, turn off the light in order Control is achieved.

In addition, when the meeting ends and the beam projector 100 is in an off state, at this time, the lighting of the conference room is first turned on, and then the electric curtain is released, the electric screen is released, and the beam projector elevation is During the re-operation, sequential control is performed in order to raise the beam projector 100 again to return to the ceiling.

Of course, the control sequence for the on (or "install") or off (or "release") operation for the auxiliary device 400 will be conveniently changed and adjusted by those skilled in the art.

The signal switching unit 320 may be possible by adding a signal delay circuit, a sequence circuit, a timer circuit, a macro function, etc. to sequentially control the output signal.

Meanwhile, in the above-described exemplary embodiments of the present invention, the first control current I1 set by the setting unit 330 turns on the beam projector 100 through the power line 110. It is characterized in that the current (A) flowing to the power supply line 110, that is, the rated current (A) specified in the beam projector 100 when the input power for supplying.

For example, assuming that the input voltage AC of the beam projector 100 generally sold on the market is 100 to 240 (V) and the power consumption is 200 to 600 Watts (W). The input current Io may be assumed to be one embodiment in the range of approximately 2 to 6 (A).

In addition, the second control current I2 set by the setting unit 330 is supplied with input power to the beam projector 100 to turn off the beam projector 100 through the power line 110. It is characterized in that the current (A) flowing through the power supply line 110 when not.

For example, suppose that the input voltage AC of the beam projector 100, which is generally sold in the market, is 100 to 240 (V) and the power consumption is 200 to 600 watts (W). In the case where the standby power is 3 to 7 watts (W), the input current Io may be assumed to be approximately 0.03 to 0.07 (A).

Therefore, it is preferable that the set second control current I2 is set to a current value A lower than the current in the standby state of the beam projector 100.

In other words, the set first control current I1 and the second control current I2 sensed by the input current Io are rated current A of a prescribed value determined according to manufacturers or specifications of the beam projector 100 and Meaning the current value (A) lower than the current (A) in the standby state may vary depending on the product type of the beam projector (100).

That is, the input current (Io) is the presentation of the conference data using the beam projector 100 in the conference room, in other words, when the lamp (Lamp) provided in the beam projector 100 is On (On) When the current A flowing through the power supply line 110 or the beam projector 100 is in a standby state for a predetermined time or more, the lamp is warmed up (for example, a power saving operation is performed). In this case, it can be assumed that a small amount of the standby current A mentioned above can also flow.

Accordingly, the beam projector 100 is typically several times to several tens of times lower than when the lamp is off or in operation when operating in the power saving mode for a predetermined time or more, as mentioned above. Since the preheating operation is performed by the standby voltage, the input current Io flowing through the power supply line 110 may be naturally lowered.

If the set first control current (I1) and the second control current (I2) as described above, the beam projector 100 is set to the current (A) flowing to the power supply line 110 during the power saving operation If it is set at 330, this will cause considerable inconvenience in proceeding with the conference since the auxiliary device 400 repeats the on or off operation every time the power saving operation is performed and the power saving operation is released.

In addition, in setting the first control current I1 and the second control current I2 through the setting unit 330, it is important to set the current A range too narrowly or too wide so that the detection is performed. Refer to the specification of the beam projector 100 so that no error occurs when the unit 200 detects the error, or when the beam projector 100 installed in the conference room is operating in a rated state or in a power saving state. It may be desirable to measure the input current Io at the time in advance and set them appropriately.

The storage unit 370 is configured to store the set current value A of the first control current I1 and the second control current I2 set by the setting unit 330.

Meanwhile, when the input current Io sensed by the detector 200 is determined as the set first control current I1, the auxiliary device 400 is turned on by interlocking with the beam projector 100. On) operation, for example, the electric screen is spread down from the ceiling, wall, etc., and the input current Io sensed by the sensing unit 200 is set by the setting unit 330. If it is determined as the control current (I2), the auxiliary device 400 is linked to the beam projector 100 to the off (Off) operation, for example, by rolling up the electric screen installed from the ceiling, wall, etc. again to the home position Will let you.

The electric screen is controlled by switching the switching unit 1 (381) by a control signal output from the controller 310, by changing the direction of the drive current supplied to the electric motor (not shown) for the electric screen It will be installed and released.

For reference, as another auxiliary device 400 included in the auxiliary device 400 in addition to the electric screen, lighting, an electric curtain, an elevation for a beam projector, and the like may also be applied to the switching unit 380 as in the operation example of the electric screen described above. Since the interlocking is performed by the switching control of each of the switching unit 2382 to the switching unit 4384 included in the description thereof will be omitted.

Each of the switching unit 1381 to the switching unit 338 included in the switching unit 380 includes at least one of a contact relay device or a non-contact logic circuit device. Would be preferred.
