Abstract

The automatic control method using a photo sensor and a sleeping sensor, automatically performs a sleeping control function in a while after checking user's sleeping state and judging the correct sleeping state. The method comprises a step for operating on a setting mode when the person is not on the bed or doesn't fall asleep or the input level of a micro computer (2) is low; a step for setting temp. difference (Δt) between in door and outdoor air as an initial temp. when the user fell asleep and the input level is high; a step for performing the operation for a certain time (ΔT1) and repeating the operation at one-step increased state for a certain time (Δt2) and finishing the sleeping operation.

The present invention relates to an air conditioner, and in particular, after setting the inaugural operation operation in the air conditioner, when the sleep state is determined by checking the day and night and sleep state using the light sensor and the sleep sensor when a certain time is determined to enter the sleep state The present invention relates to an automatic sleep control method of an air conditioner that automatically performs a sleep control function.

Conventionally, the air conditioner is used to set a bedtime operation time by using a remote control, and the driving of the air conditioner is stopped for a predetermined time regardless of sleep or not. In this mode of operation, even when you do not sleep, the air conditioner stops working after a predetermined period of time has passed, the user has to reset the sleep state of the air conditioner again.

The present invention is to overcome this inconvenience, its purpose is to compare the temperature difference in the room when the sleep state is determined by using the light sensor and the sleep sensor to compare the temperature difference of the room to drive the air conditioner to sleep the most comfortable temperature The present invention provides an automatic control method of inaugural operation of an air conditioner performed for a predetermined time.

As shown in the figure, the control device detects the sleep state by detecting the flow state of the body (3), the light sensor (1) to detect the day and night, the indoor and outdoor temperature sensing the indoor and outdoor temperature Sensors 5 and 7, an amplification circuit 4 for amplifying the output signal of the sleep sensor, a buffer 6, and a microcomputer 2 for receiving and processing signals from the sensors to control the optimal operating state of the air conditioner. It consists of.

The sleep sensor 3 uses a piezoelectric element as a material, and the piezoelectric element is pressurized to the surface and generates a minute voltage signal.

The sleep sensor 3 is placed on a bed lying down by a person.

FIG. 2 shows the voltage output waveform from the sleep sensor 3. As can be seen from this waveform diagram, when an object is placed on the sleep sensor 3, when entering a bed (granular), when lying, The output waveforms vary depending on the state, such as when in a state.

In addition, the optical sensor 1 of FIG. 1 is a sensor for detecting day and night, and when it is bright, the optical sensor 1 is in a low state, and the input voltage to the microcomputer 2 is in a low state. On the contrary, the input voltage to the microcomputer 2 is in a high state, and the microcomputer 2 determines day and night according to the input voltage.

The indoor and outdoor temperature sensors 5 and 7 sense the indoor and outdoor temperatures, respectively, and input them to the microcomputer 2, and the microcomputer 2 receives the output signals from these sensors to determine the indoor and outdoor temperatures. do.

The control operation of the microcomputer 2 will now be described in detail with reference to the third flowchart.

If sleep sensor 3, the output voltage V1 is the reference maximum voltage Va equal to or less than the from there it is not necessary to control the air conditioner not a standing state (S1-S4), the output voltage V ₁ is the reference when the lowest voltage Va or more, based on It is the state after the state of granulation when it is between the lowest voltage Va and the maximum voltage Vb. If the voltage state is maintained for a certain time (T1), it is judged as the state of regeneration after the granulation (there is a person in the bedroom), Determine.

In this case, the resetting bit is set.If a large movement is detected during the predetermined time and the input voltage V1 is detected to be higher than the highest reference voltage Vb, the counted time until then is cleared and the check is performed again for a predetermined time T1. If it is determined that there is no large movement, it is judged completely at that time and the reconstruction bit is set (S5-S10).

Thereafter, if there is no large movement in which the input voltage V1 becomes higher than the highest reference voltage Vb for a predetermined time T2, it is determined as a sleep state and the sleep state bit is set.

On the other hand, if a large motion is detected, time setting (T2) is again performed to check whether sleep is performed through the same process as in steps S6 to S10 (S11 to S16).

If the input voltage V1 is greater than the reference maximum voltage Vb, if the input voltage V1 is checked and falls below the reference voltage after a predetermined time (T3), it is judged that it is not a person and does not perform the control. The control branches to step S11 to perform control (S17-S21).

4 is a flow chart illustrating the case where the air conditioner is currently running and the reconstruction bit and the sleep state bit are set.

The microcomputer (2) checks the input terminal of the optical sensor (1), and if it is not a re-bit set or sleep bit set, or if the pressure of the microcomputer (2) is low, it is judged weekly and operates in the existing setting mode. .

If the set of regeneration bits, the set of sleep state bits, and the input of the microcomputer 2 is high, it is judged to be night and starts the sleep operation without any external operation (S1-S9).

The initial set temperature at this time is to check the temperature detected by the indoor and outdoor sensors (5, 7), set the temperature difference (△ T) closest to the comfort of the human body heat sense, and operate for △ t ₁ hour After Δt ₁ has elapsed, the set temperature is increased one step in consideration of the decrease in body temperature, and after the operation is performed for Δt ₂ , the sleeping operation is terminated and the air conditioner is stopped (S10-S16).

As described above, the air conditioner driving control apparatus according to the present invention is optimized without the external key operation in consideration of the indoor and outdoor temperature after fully understanding the sleep state using the sleep sensor 3 and the light sensor 1. It is possible to operate the air conditioner in the temperature state, so there is no need to set the time again even when the user does not enter the sleep state after going to bed operation, which makes the use of the product more convenient.
