The first time T1 is greater than the first reference time TR1 and has a time smaller than the operation holding time TM2.

Operation of the power save control device of the present invention according to the above configuration is as follows.

Operation of the power save control device of the present invention shown in Figure 1 is as follows.

FIG. 2 is an operational waveform diagram of the power save control apparatus of the present invention of FIG. 1.

The human body detecting unit 110 detects heat or movement of the human body by the infrared sensor or the RF signal detecting sensor according to the presence of the person, and outputs the activated detection signal S when the human is present.

The first reverse counter 120 receives the detection signal S and counts the counter signal until the counter value is reset at the lighting holding time TM1 of the luminaire 140 set by the user each time the detection signal S is activated. The activated lighting control signal C1 is output from the start of counting until the counter value is reset, and the disabled lighting control signal C1 is output when the counter value is reset. That is, as shown in FIG. 2, when the detection signal S, which is the output of the human body detecting unit 110, is activated once at t1, the first reverse counter 120 starts reverse counting from the lighting holding time TM1. Outputs the activated lighting control signal C1. After the lighting control signal C1 is activated, when the human body detecting unit 110 detects the heat or the human movement again at time t3 and the detection signal S is activated again, the first reverse counter 120 maintains lighting again. The initial value is set to the time TM1 and the counter counting is restarted. If no detection signal S is activated until the counter value of the first counter counter 120 is reset, the output of the first counter counter 120 is turned on. The control signal C1 is deactivated at time t5. After the predetermined time elapses, when the human body detecting unit 110 detects the heat or the human movement again at t7 hours and the detection signal S is activated again, the first reverse counter 120 turns on the holding time TM1 as described above. Set the initial value and start counting to output the activated detection signal (S) until the counter value of the first reverse counter 120 is reset, and if the counter value of the first reverse counter 120 is reset The lighting control signal C1, which is the output of the first reverse counter 120, is deactivated at time t10.

When the lighting control signal C1 is activated, the luminaire control unit 130 turns on the transistor TR and turns it on at the first supply voltage Vcc by the second resistor R2, the photodiode PD, and the transistor TR. The current flows to the ground voltage of 2 supply voltage Vss, so that the phototransistor PTR is turned on to activate the switching control signal SWC. The triac TC is turned on by the activated switching control signal SWC, and the lamp 140 is turned on by turning on the triac TC to turn on the lamp 140. On the contrary, when the lighting control signal C1 is inactivated, the transistor TR is turned off, so that the power supply AC is cut off and the luminaire 140 is turned off. That is, as shown in FIG. 2, since the lighting control signal C1 is activated during the time t1 to t5 hours and the time t7 to t10 hours, the luminaire 140 is turned on, and the t5 time to t7 hours after t10 hours. Since the lighting control signal C1 is inactivated, the lamp 140 is turned off.

The time comparison unit 150 compares the user-specified second time RTI with the current time CTI, and compares the activated time comparison time CP with the second time RTI and the current time CTI equal to each other. The first switching means SW1 is turned on when the time control signal TE is activated to output a time comparison time CP, and when the time comparison time CP is activated, the transistor TR is turned on so that the luminaire ( 140 is lit. As such, the time comparison unit 150 and the first switching unit SW1 may be provided to continuously light the lamp 140 for a specific time period determined by the user.

The second reverse counter 210 is the same as the operation of the first reverse counter 120. However, since the initial setting value of the second counter counter 210 is the operation holding time TM2 of the air conditioning apparatus set by the user, when the second station counter 210 is reset by starting the counter counting at the operation holding time TM2, the second station counter 210 is reset. Will count up. That is, as shown in FIG. 2, the operation holding time TM2 may be longer than the lighting holding time TM1. The reason is that if the air conditioner is frequently turned on or off, a lot of power consumption may occur.

Therefore, as shown in FIG. 2, the operation start signal MC, which is the output of the second reverse counter 210, is activated at t1 hour, which is the time at which the detection signal S is activated, to start counting, and at t3 time, the detection signal. Since (S) is activated again, the operation start signal MC is activated during the operation holding time TM2 for t3 to t6 hours, and the operation start signal MC is deactivated for the t6 time from t6 to t7 hours. When (S) is activated, the operation start signal MC is activated from t7 hours to t11 hours, and deactivates after t11 hours.

Since the first input terminal AB of the first single-stable multivibrator 231 is connected to the second supply voltage Vss, and the second input terminal B is connected to the operation start signal MC, the first single-stable multivibrator 231 The vibrator 231 is activated at time t1, which is the rising time of the operation start signal MC, and is activated until t2 time, which is during the first reference time TR1 determined by the time constant value of the resistor Rx1 and the capacitor Cx1. After t2 hours, the heating and cooling control signal DO is deactivated. In the same manner as above, the heating and cooling control signal DO is activated at a time t7 at which the operation start signal MC is activated again, and remains active for the first reference time TR1, and the heating and cooling control signal at the time t8 is performed. DO) is deactivated. At time t3, the detection signal S is activated, but the operation start signal MC is in an activated state, so the heating / cooling control signal DO is in an inactive state.

The air conditioning unit starts operation when the air conditioning control signal DO is activated. The air conditioning unit and the air conditioner control signal DO of the present invention may be connected by wire or wirelessly to control the operation of the air conditioner by the air conditioner control signal DO.

As described above, even if the detection signal S is activated before the second reverse counter 210 is reset by reverse counting from the operation holding time TM2, the heating / cooling control signal DO is activated when the initial detection signal S is activated. Only activated so that the heating and cooling system is started only once.

The delay unit 220 inverts the operation start signal MC and delays the inverted operation start signal MCB for a first time T1 to output the delay operation start signal DMC. The first time T1 is larger than the first reference time TR1 and smaller than the operation holding time TM2.

Since the first input terminal AB of the second single-stable multivibrator 235 is connected to the operation start signal MC, and the second input terminal B is connected to the delay operation start signal DMC, the second single-stable multivibrator 235 The vibrator 235 is operated during the second reference time TR2 determined by the time constant value of the resistor Rx2 and the capacitor Cx2 at the rise time of the delay operation start signal DMC when the operation start signal MC is deactivated. The heating / off control signal DOF is activated during the second reference time TR2 at the falling time of the operation start signal MC when the activated off control signal DOF is output or the delay operation start signal DMC is activated. . Therefore, the heating / heating off control signal DOF is deactivated and the operation start signal MC is deactivated and is activated at the time t12, which is the rising time of the delay operation start signal DMC, and is controlled by the time constant value of the resistor Rx2 and the capacitor Cx2. It continues to be activated until time t13 which is during the 2nd reference time TR2 which is determined, and after t13 time, the air conditioning heating control signal DOF is deactivated.

The light emitting signal generator 240 outputs a light emitting temperature signal (LO) or a light emitting off signal (LOF) directly to the light receiving unit of the air conditioner in the case of the air conditioner having a light receiving unit for controlling the operation of the air conditioner on the remote controller. By controlling the operation, the light emission signal generating unit 240 is composed of a light emitting on-signal output unit 241 and a light emitting off-signal output unit 243.

As shown in FIG. 2, the light emitting temperature signal output unit 241 emits light as a light emitting signal to the light receiving unit of the air conditioning apparatus for t2 hours at t1 and t8 hours at which the heating and cooling control signal DO is activated. Outputs the signal LO to turn on the air conditioner, and the light-off signal output unit 243 is a light-off signal that is a light-emitting signal to the light-receiving unit of the air-conditioner when the air conditioning control signal DOF is activated for t13 hours. Outputs the signal LOF to turn off the heating and cooling system.

As described above, the detection signal S is activated by the second counter counter 210, the delay unit 220, and the second single-stable multivibrator 233 to detect the detection signal S within a predetermined time when the air conditioner is operating. Even if is activated, the heating and cooling off control signal (DOF) is to be deactivated, and if the detection signal (S) is not activated after a certain period of time by activating the heating and cooling off control signal (DOF) to stop the operation of the heating and cooling device in operation frequently It is possible to prevent the heating and cooling device to be turned on or off to prevent unnecessary power consumption. That is, if there is a person in the room detects this in the human body detecting unit 110 to operate the heating and cooling device, after that even if there is no person in the room, if the person comes back to the room within a certain time, the heating and cooling off control signal (DOF) is The air conditioning unit is deactivated and continues to operate. If a person does not enter the room after a certain time, the air conditioning unit is activated by activating the air conditioning off control signal (DOF).

Figure 4 is a configuration diagram of the position determination unit, as shown in Figure 4, each office or each room of the building or home is installed the human body detection unit 110 shown in Figure 1, when the user goes out of the office or home Activate the position determination control signal PEN by using a switch or the like. The position determination unit 300 starts to operate by the activated position determination control signal PEN, and the position determination unit 300 includes a plurality of human body detection units 110a to each room mounted in each office or home of a building. The position signal is determined by determining whether the plurality of sensing signals Sa to Sn output from 110n are activated, and the positions of the human body sensing units 110a to 110n outputting the activated sensing signals Sa to Sn. (PS) is output. In other words, the location signal PS indicating the position of the human body detecting units 110a to 110n outputting the activated detection signals Sa to Sn is displayed on a monitor or the like to indicate in which office there is an external intruder. Know the location of the anti-theft can be prevented.

3 is a configuration diagram of another embodiment of the power save control device of the present invention, the operation of the power save control device of the present invention of another embodiment of FIG. 3 is the same as the operation of the power save control device of FIG. However, in the case of FIG. 1, the operation of the lighting device 140 or the heating / cooling device is controlled by the detection signal S output by the human body detecting unit 110 for detecting the movement of a person, but the power saving control device of FIG. 3. Is a detection signal (S) by the human body detection unit 110, the illumination intensity detection signal (LUX) that is the output of the illumination detection unit 160 by the photoconductive cell (CDS) that varies depending on the illumination, that is, day and night, and the detection signal The lighting of the lamp 140 is controlled according to whether the illumination detection signal LS, which is the logical product of the S and the illumination detection signal LUX, is activated, and the temperature comparison signal TCM that is the output of the temperature comparison unit 250 is controlled. And the temperature detection signal TS obtained by logically multiplying the detection signal S and the temperature comparison signal TCM and the detection signal S.

That is, as illustrated in FIG. 3, the illuminance detection unit 160 includes a photoconductive cell CDS connected in series with the first resistor R1 and the first resistor R1, so that the light conduction is performed at night with low illumination. The resistance value of the cell CDS is increased to output the activated illuminance detection signal LUX. In the daytime when the illuminance is high, the resistance value of the photoconductive cell CDS becomes small and the illuminance detection signal LUX is deactivated.

The first selector 170 selects one of the detection signal S, the illumination detection signal LUX, or the illumination detection signal LS according to the logic value of the first selection signal SEL1, and the like control signal. Outputs (LCT). For example, if the first selection signal SEL1 has a binary number 00, the equal control signal LCT becomes the detection signal S, and if the first selection signal SEL1 has a binary number 01, the equal control signal LCT is illuminance When the first selection signal SEL1 has the binary number 10, the equal control signal LCT becomes the illuminance detection signal LUX. In FIG. 3, when the ground voltage Vss is input to the input terminal of the first selector 170, and the first select signal SEL1 has the binary number 11, the light control signal LCT is deactivated, which is a low logic value. You can always turn off).

Any one of the signals is selected, and the lamp 140 is turned on according to whether the lamp control signal LCT is activated in the same manner as in the operation of FIG. 1.

As shown in FIG. 3, the temperature comparison unit 250 compares the current temperature TC of the place where the air conditioning and heating apparatus is installed with the reference temperature TR set by the user, and outputs a temperature comparison signal TCM. For example, when the first temperature comparison unit 251 is a temperature comparison unit related to a cooling device, and the second temperature comparison unit 253 is a temperature comparison unit related to a heating device, the first temperature comparison unit 251 is a current temperature.
