External control device for driving electric devices and external control method of the external control device {EXTERNAL DEVICE AND METHOD OF CONTROLLING ELECTRIC APPARATUS'S DRIVE BY THE EXTERNAL DEVICE}

The present invention relates to an external control device for driving an electric device and an external control method for the external control device, and more particularly, to supply power to a driving unit of an electric device such as a gas supply device, a water supply device, an air conditioner, and the like. In further control from the outside of the device, by detecting the rate of change of the voltage or current in a specific device that operates in accordance with whether the driving unit of the elements provided in the electrical device to determine whether to drive the driving unit of the electrical device An external control device for driving an electric device and an external control method for the external control device for additionally controlling the control unit of the electric device by transmitting a control signal for controlling whether or not a driving power is supplied to the control unit of the electric device.

Modern living spaces are equipped with a variety of sources that make everyday life very convenient. In particular, water supplies that provide comfortable clean water use, gas supplies that provide sufficient thermal power for cooking food at low cost, and electricity sources that allow the use of various electrical devices, such as lamps, It is a well-known fact that it is an essential equipment in living space. According to the purpose of the building, all the above-mentioned facilities are provided in the case of a residential space, and in the case of a non-residential space, that is, an office, a lecture room, etc., an electricity supply source is essentially provided.

However, while such facilities make people's lives very convenient, there is a danger of causing a big accident when a small breakdown or malfunction occurs. In particular, when such a failure or malfunction occurs, if a person is not in the space and is left for a long time, the possibility of a big accident is much greater.

For example, in the case of gas, if a person goes out for a long time without opening the valve without knowing that there is a leak, or if the stove is turned on, the gas will leak out and collect in the room. When entering, breathing may cause illness, and there is a danger of close fires leading to large explosions and fires.

In addition to such a big accident, the waste of energy due to leakage of electricity and water is also a serious problem. In particular, offices, lecture halls, public buildings, etc. require high illumination, and many people come and go from time to time due to the nature of the building use, so in most cases, a lot of power is consumed by turning on the lights.

However, in the case of a classroom, for example, the last person to turn off the light or air conditioner after the lecture ends, but the last person to leave is unclear, and behavioral psychology is distributed among many people. It is well known that extinction in spaces used by many people does not work well, as it is well known that the probability of doing something by yourself is extremely low.

As such, although there is no need to turn on the air conditioner because there are no people in the space, the amount of waste of power generated by the air conditioner being kept on is very large. In addition, it is not possible to exclude the problem that various problems such as damage to the electrical equipment due to overheating and deterioration of furniture, accessories, etc. in the space due to the lamp is left for a long time continuously.

However, in recent years, many electric devices such as air conditioners adopt an independent control method for each device. In this case, in order to remotely control the electric devices, whether the independent electric control device is in a driving state or a standby mode in which driving is stopped. It is difficult to detect automatically from an external or remote location, and the controllers of the electric device are configured to be suitable for an independent control method, which makes it difficult to modify the control unit to control driving and driving stops externally or remotely.

For example, when the electric device is an air conditioner, many technologies have been introduced for the automatic control method of the air conditioner. However, in recent years, the automatic control method of the remote control has many technical difficulties in controlling the air conditioner automatically because many air conditioners are not installed with the remote control.

As a forced shutoff method, the power supply is cut off or the outdoor unit is turned off. However, this method is not easily selected by the user because it may damage the circuit and the compressor of the air conditioner itself.

Recently, since most electronic products use a program on / off method using a remote control, automatic control technology is very difficult to apply. The reason is that each company's model has different on-off programs, so automatic control is almost impossible without matching protocols with other devices. Therefore, there is no power-saving technology for energy saving in the low-carbon power-saving era these days, many difficulties arise.

Therefore, in order to solve this problem, it is required to develop an external control device that detects the absence of a person in the room and controls the driving of the electric device from the outside while maintaining a standby mode for power, gas, and electricity. .

The electric device 200 includes a power supply for converting and supplying AC power input through a power plug into driving power required by the driving unit. The controller of the electric apparatus 200 receives standby power from the power supply and maintains the driving state at all times.

For example, the driving determination unit 10 may include a voltage check terminal connected to the plus terminal and the minus terminal of the power supply unit, and may detect a voltage change in the power supply unit through the voltage check terminal.

In addition, the driving determination unit 10 may determine whether the driving unit of the electric device 200 is driven by detecting a change in voltage of both ends of the motor driving the driving unit of the electric device 200 or a temperature change of the motor.

In addition, the driving determination unit 10 measures the amount of motor driving current applied to the motor driving unit to drive the motor, and whether the driving unit of the electric device 200 is being driven by the measured amount of the motor driving current. You can also determine whether or not.

The electric device 200 includes a control signal generator for generating a control signal for controlling the opening and closing of the power supply switch of the electric device 200. That is, the control signal generator of the electric device 200 generates a control signal for controlling the supply of driving power from the power supply. The driving determination unit 10 may determine whether the driving unit of the electric device 200 is driven by reading the voltage level of the control signal output from the control signal generator.

The electric device 200 includes a voltage display unit that displays the level of the voltage in a specific device that operates according to whether the driving unit of the electric device 200 is driven. The voltage display part includes a seven-segment or seven-segment LED light emitting device and displays a voltage level at the specific device.

By using a signal from the sensing unit 20, a source (ie, water, gas, electricity, etc.) of the electric device 200 may be connected or disconnected to the electric device 200.

The control signal transmitting unit 30 transmits a control signal for controlling whether to supply driving power to the control unit of the electric device 200 to control the power supply to the driving unit of the electric device 200.

The control signal transmitter 30 is a concept including a circuit diagram located inside an external control apparatus for driving the electric apparatus 200, a microcomputer designed on the circuit diagram, and the like, and a method of operating the control signal transmitter 30 will be described below. It will be described in more detail.

Figure 2 shows a first embodiment of the operating flowchart of an external control device for driving an electric apparatus according to the present invention. First, the control signal transmitter 30 determines whether the electric device 200 is being driven by the drive determination unit 10. As a result of the determination by the driving determination unit 10, when the electric apparatus 200 is being driven (S101-Yes), the control signal transmitter 30 next checks whether the body fuselage is detected by the fuselage detector 20. It is determined whether or not (S102).

At this time, when the fuselage is detected by the one or more fuselage detecting sensors (S102-Yes), the control signal transmitting unit 30 controls to maintain the power supply to the drive unit of the electrical apparatus 200 (S103), If the fuselage is not detected by the above fuselage detecting sensor (S102-No), the control signal transmitting unit 30 controls to cut off the power supply to the driving unit of the electric apparatus 200 (S104). If negative for step S101, feedback to the initial state is performed so that continuous detection of voltage, current, temperature, or signal is made.

That is, in the first embodiment, the control signal transmitting unit 30 determines that the electric apparatus 200 is being driven by the driving determining unit 10, and when the presence of the indoor fuselage is detected by the fuselage detecting unit 20, the electric signal is detected. If it is determined that the power supply of the device 200 is maintained, and the electric device 200 is driven by the driving determination unit 10, and the presence of the indoor fuselage is not detected by the fuselage detecting unit 20, the electric device ( It is to control to cut off the power supply of 200).

The control signal transmitting unit 30 operates as shown in the flowchart of FIG. 2, so that the fuselage detecting unit 20 does not detect the entry or exit of the fuselage (that is, even if the entrance and exit direction of the fuselage is not detected). The presence or absence of the fuselage in the 100 may be used to determine the entry or exit of the fuselage and thus accurately determine the maintenance or blocking of the supply source.

Here, as shown in the system diagram of FIG. 1, the external control device for driving the electric apparatus of the present invention may further include a timer 40. The timer 40 is a device for measuring time, and the control signal transmitter 30 may be programmed by the timer 40 to perform various operations.

Figure 3 shows a second embodiment of the operating flow chart of the external control device for driving the electric device according to the present invention. First, the control signal transmitter 30 determines whether the electric device 200 is being driven by the drive determination unit 10 (S201). If it is determined by the drive determination unit 10 that the electric device 200 is being driven (S201-Yes), the external control device for driving the electric device 200 starts to operate the timer 40 (S202).

If the presence of the indoor fuselage is detected by the fuselage detector 20 after the electric device 200 is driven (S203-No), the control signal transmitter 30 determines that a person remains in the installation space 100. And return to the initial state. However, if the presence of the indoor fuselage is not detected by the fuselage detector 20 after determining that the electric device 200 is being driven by the drive determiner 10 (S203-Yes), the control signal transmitter 30 Determines whether the first predetermined time has elapsed (S204).

If the first predetermined time has not yet elapsed (S204-No), the fuselage detecting unit 20 determines whether the presence of the fuselage is detected again, and this step is cycled, and the first predetermined time has elapsed. If it is determined (S204-Yes), the control signal transmitting unit 30 transmits a control signal for cutting off the power supply of the electric device 200 to the control unit of the electric device 200 (S205).

In this case, the first predetermined time is preferably in the range of 5 seconds to 5 minutes. The operation of the timer 40 may be performed immediately after it is determined by the driving determination unit 10 that the electric device 200 is being driven.

As described above, the timer 40 is further provided, and the control signal transmitter 30 further controls the interruption or maintenance of the supply source to the electric device 200 by further using the timer 40. It will be able to cope with a variety of situations. When using the timer 40 as in the second embodiment, it is possible to prevent unnecessary power waste by maintaining or shutting off the power supply after checking whether the detection of the indoor fuselage occurs during the first predetermined time. have.

In addition, the external control device for driving the electric apparatus according to the present invention may be implemented to include a dial. The user may rotate the dial to set the time of the first predetermined time. Since the dial serves to set the first predetermined time mentioned above, there is an effect of improving the convenience of use. The dial may be implemented as a setting button of a digital input type. In addition, a reset button may be added to implement a reset of the predetermined first predetermined time when the reset button is pressed.

The preferred time of the first predetermined time has been described as 5 seconds to 5 minutes, which may be appropriately set according to various factors such as the type, purpose of use, and characteristics of the installation space 100 or the electric device 200. . When the installation space 100 is a residential space of a general home, the first predetermined time may be about 5 minutes, and in the case of an office, the first predetermined time may be about 10 minutes.

For example, when the installation space 100 in which the electric control device of the electric drive of the present invention is installed is a toilet of a private living space and the electric device 200 is a light of the toilet, the external control device is a person's toilet. It is preferable that the first predetermined time is about 5 seconds to about 10 seconds because it is preferable to react immediately upon entering and exiting.

In addition, when the electric device 200 is an electric supply device of the fan, it is preferable to operate the filter for a long time to remove odor even after a person leaves the toilet, so that the first predetermined time for the fan may be about 10 to 20 minutes. will be.

In addition, when the installation space 100 in which the external control device for driving the electric device of the present invention is installed is a large lecture room and the electrical device 200 is an air conditioner of the lecture room, the first predetermined time is longer than this short. This is advantageous. In more detail, the air conditioner is turned on, but the indoors are not immediately cooled, but a predetermined time is required, and even if the air conditioner is turned off, the indoors preserve some of the cold air. In other words, unlike in the case of a lamp having no time difference between the on / off operation of the electric device 200 and the effect thereof, in the case of an air conditioner, the on / off operation of the air conditioner and its effects (air conditioning on-indoor air cooling / Air conditioning off-cooling off) will appear at some time. Therefore, when the electrical apparatus 200 is a classroom air conditioner, it is preferable to make the said 1st predetermined time into a moderately long time, ie, about 3 to 5 minutes.

In summary, it is preferable that the first predetermined time is a time within a range of 5 seconds to 5 minutes. Thus, the first predetermined time may be a time in various ranges according to the type or characteristics of the electric device 200. It can be expressed together. That is, when the electric device 200 is a lamp, the first predetermined time may be about 5 seconds to about 10 seconds, and when the electric device 200 is an air conditioner, the first predetermined time may be about 3 minutes to about 5 minutes. As such, the first predetermined time may be appropriately set according to characteristics or purposes of the installation space 100 and the electric device 200.

An external control device for driving an electric apparatus according to the present invention includes a relay switch unit having a relay terminal connected to a power supply terminal (on / off contact terminal) of the electric apparatus 200. The control signal transmitting unit 30 may control the power supply to the driving unit of the electric device 200 by opening and closing the contact of the relay terminal. The control signal transmitting unit 30 includes the relay switch unit.

The relay switch unit opens and closes relay contacts by connecting and disconnecting between relay contacts by a relay coil magnetized by a change in voltage or current in the specific device.

The relay switch unit transmits a relay contact signal indicating that the relay contact is connected and disconnected to the control unit of the electric device 200. In this case, the controller of the electric device 200 may control the supply of driving power from the power supply unit of the electric device 200 by opening and closing the power supply switch of the electric device 200 according to the relay contact signal.

Relay uses a property that becomes a magnet when a current flows through the coil. When the coil is an electromagnet, the iron plate is pulled to close or open the contact point of the switch unit attached to the iron plate. The relay may be used to interlock an electrically independent circuit. For example, by the operation of a circuit composed of a low voltage meter such as 5V, the circuit of an AC 100V system can be turned on or off or a large current circuit can be turned off.

The control signal transmitter 30 determines whether the electric device 200 is being driven by the drive determination unit 10, and determines whether or not the presence of the indoor body is detected by the fuselage detector 20.

As a result of the determination, when the electric device 200 is being driven and the fuselage in the installation space 100 is not detected, the control signal transmitting unit 30 short-circuits and opens the contact between the relay terminals instantaneously and opens the relay contact point. At this moment, the relay contact signal indicating that it is attached and dropped is transmitted to the controller of the electric apparatus 200. When the control unit of the electric device 200 receives the relay contact signal, the power supply of the electric device 200 is cut off by short-circuiting and opening the power supply switch of the electric device 200.

In addition, the external control device for driving the electric device according to the present invention directly transmits a control signal for controlling whether or not the driving power supply from the control signal transmitter 30 to the controller of the electric device 200 to the electric device 200 It may be implemented to control the power supply to the drive of the.
