Intelligent learning control method for standby power saving controller

The invention relates to a power saving control technology for an electric appliance, in particular to a smart learning control method for a standby power saving controller of an electric appliance.

With the development of electronic technology becoming more and more mature, all kinds of electrical equipment and equipment are more inseparable from people's lives. All TVs, air conditioners, microwave ovens, etc. are common electrical appliances in every household. In designing these electrical devices, most household electrical appliances are designed to have a standby function in order to take into account the convenience of the user when turning on/off during use and the ability to achieve quick start-up.

Since most of the electrical equipment has a standby function, when the general user does not use the electrical equipment, although the electrical equipment is considered to have been turned off, the electrical equipment remains in the standby state. Electrical equipment in standby still consumes power. Although each electrical device consumes less power when not in use, for example, TV standby power consumption ranges from 6 to 15 watts, microwave oven standby power consumption ranges from 0.1 to 4.2 watts, and audio standby power consumption ranges from 0.04 to 14.9. The tiles are not equal, but the power consumed by each appliance in the standby state is still considerable. In this way, not only is the waste of electricity, but also the increase in electricity bills. This is contrary to the current trend of energy conservation advocated.

In view of the fact that the electrical equipment still consumes a large amount of accumulated electric energy in the standby state, the operator has also designed an energy-saving controller that can further automatically power off in the standby state, so that the electrical equipment can be cut off when in standby state. The connection between electrical equipment and power supply to achieve better energy saving.

However, whether it is the design of a general energy-saving controller or an energy-saving controller product with an automatic power-off function, there is still a major deficiency, that is, when the energy-saving controller is used in conjunction with the standard electrical equipment, due to the rating of each electrical equipment The power is not the same, and the standby power consumed during design standby is different. Therefore, when the energy-saving controller is used in different electrical equipment, there may be a situation of misjudgment, and the same energy-saving controller often occurs. It can be used normally when applied to one electrical device, but it cannot be operated normally when it is used for another electrical device.

Therefore, an object of the present invention is to provide a smart learning control method for a standby power saving controller of an electric appliance, so that the smart learning function of the present invention can make the power saving controller correctly apply when applied to any one of the electrical appliances. operating.

The technical means adopted by the present invention to solve the problems of the prior art is that when a learning start switch is detected to be operated, the control unit controls the circuit to open and close the circuit, and the current detecting unit detects the current of the power circuit. And define this current as the standby current value. The control unit controls the loop switch to open when the electrical device is not powered on during a predetermined time period. During the preset time period, if the electrical device is powered on and used The current detecting unit detects the current of the power circuit and defines the current as the starting current value. The standby current value and the startup current value can be memorized in the memory unit as a basis for judging whether to perform the standby power saving function in the future.

In the preferred embodiment of the present invention, the learning start switch can be a manually operated switch or an infrared receiving unit capable of receiving a remote start signal, so that the user can perform wireless control by using a remote controller configured by a general electrical device. It is also possible to press the operation switch.

According to the smart learning control method of the present invention, when the electrical equipment is connected to the power supply circuit via the standby power-saving controller, the correct standby current value and the rated value of the target electrical equipment can be detected by a smart learning process of a predetermined procedure. The starting current value is used as a basis for judging whether or not to execute the standby power saving function in the future, and there is no occurrence of a misjudgment when the conventional energy saving controller is used in different electrical equipment.

Furthermore, the present invention can use the power-on current value as a function of overload warning determination. When an electrical device is in use, if an overload condition occurs, the warning device can detect and issue a warning, and the design of cutting off the electrical energy supplied to the electrical device can be added.

Referring to FIG. 2, it shows a flow chart of the smart learning control method of the standby power saving controller of the electrical equipment of the present invention. As shown in Fig. 1, when the smart learning of standby energy saving is performed, the electric appliance 2 is connected to the power source 1 via the power saving controller 100 and the power circuit 12 (step 101), at which time the node p1 can be sensed via the resistor 17. The voltage signal generates a wake-up signal S1 to the wake-up signal input terminal HV of the control unit 3.

At this time, if the user presses the operation learning start switch 4 (step 102), the control unit 3 outputs a signal to the drive unit 5 via the loop switch drive output terminal IO, and the drive unit 5 makes the loop switch 16 The exciting coil 162 is energized to control the common contact 161a and the normally open contact 161c in the circuit switch 16 to be closed (step 103).

The control unit 3 receives the power-on current value 31b and memorizes the power-on current value 31b in the memory unit 31 (step 110).

After learning and memorizing the standby current value 31a and the starting current value 31b of the electrical device 2, the control unit 3 can further perform the automatic power-off control when the electrical device is in the standby state. When the user wants to use the electrical device 2, the remote controller 91 can be operated to generate a remote start signal S2 to the infrared receiving unit 9. After the control unit 3 receives the remote start signal S2 via the infrared receiving unit 9, the control unit 3 can receive the remote start signal S2.

Referring to Figure 4, there is shown a flow chart of the present invention when power is detected and then re-powered. When the current detecting unit 14 detects that the power supply 1 is interrupted and then re-powers (step 301), the voltage signal of the node p1 is sensed via the resistor 17, and a wake-up signal S1 is generated to the wake-up signal input of the control unit 3. End HV. At this time, the control unit 3 first determines whether the electrical device 2 is connected to the power circuit 12 (step 302), and if so, the control unit 3 controls the circuit switch 16 to be closed (step 303) to continue supplying power to the electrical device 2. If it is determined that the electrical device 2 is not connected to the power circuit 12, the control unit 3 controls the circuit switch 16 to open (step 304) to suspend power supply to the power circuit 12. This function of the power-on judgment can provide a working state before the power-off, for example, for certain specific loads (for example, a rechargeable battery of a notebook computer).

Referring to FIG. 5, the power saving controller 100 of the present invention can be set in the A power supply terminal 13 is connected to a socket panel 132 and is embedded in a wall.
