Obviously, the described embodiments are only It is a part of embodiments of the present invention, but not all embodiments. The components of the embodiments of the invention generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Accordingly, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

In order to facilitate the understanding of this embodiment, a method for controlling the working state of the socket disclosed in the embodiment of the present invention is firstly introduced in detail. state, and by generating corresponding control signals, control the power-off of the socket where the electrical appliance is located.

Considering that when the main power supply of the electrical appliance is not unplugged, the electrical appliance is in a standby state, and some devices are still running and consume power, and there are certain safety hazards. However, it is necessary to manually unplug the power supply or disconnect the The main switch brings certain inconvenience to people's life. Based on this, an embodiment of the present invention provides a method for controlling the working state of a jack, which will be described below through an embodiment.

As shown in Figure 1, the method includes steps S101-S103, specifically as follows:

Step S101: Obtain the amplitude of the current electrical signal of the controlled socket where the electrical appliance is located;

First, turn on the main switch, and the single-chip microcomputer sends a power-on signal to the normally open relay to control the power-on of the corresponding controlled jack, and then collect the electrical signal of the controlled jack through the voltage and current sensor connected to the controlled jack , and send the electric signal to the A/D converter, and the A/D converter converts the electric signal into a digital signal, and sends it to the single-chip microcomputer for calculation and processing to obtain the current electric signal amplitude.

Specifically, the current electrical signal amplitude includes at least one of voltage, current, power, power consumption, etc., and power is generally selected as the current electrical signal amplitude. In order to facilitate users to intuitively monitor electrical appliances through the amplitude of the electrical signal, the amplitude of the electrical signal can be displayed on a display connected to the single-chip microcomputer.

It should be noted that a processing program is pre-stored in the single-chip microcomputer. In one embodiment provided by the present invention, the processing program includes various parameter calculation and judgment programs, data sending and receiving subroutines, timer subroutines and display subroutines. program etc.

In a specific embodiment provided by the present invention, the above-mentioned single-chip microcomputer can be a 9S12XE series single-chip microcomputer, and only a single-chip microcomputer that can realize the above-mentioned functions can be selected.

It should be noted that, in the above-mentioned embodiments, only exemplary descriptions are made, and there are still many ways of modification in the prior art that can also realize this step, which will not be repeated here, and all of them are within the scope of protection of the present application Inside.

Step S102: judging whether the amplitude of the current electrical signal is greater than a preset jack threshold;

Through step S101, after obtaining the amplitude of the current electrical signal of the controlled jack where the electrical appliance is located, next, it is necessary to determine whether the amplitude of the current electrical signal is greater than the preset threshold of the jack.

Generally speaking, the jack threshold is selected as a power parameter, therefore, at this time, the amplitude of the above-mentioned current electrical signal is also selected as a power parameter.

It should be noted that this method needs to set a preset jack threshold when it is used. At the same time, this method is applicable to different working states such as power-off and standby of electrical appliances according to actual needs. Taking the power-off state as an example, the preset The jack threshold is obtained as follows:

respectively measuring twice the amplitude of the electrical signal of the controlled jack where the electrical appliance is in the shutdown state, to determine the first amplitude and the second amplitude;

judging whether the deviation ratio between the first amplitude value and the second amplitude value is smaller than a preset ratio threshold,

If yes, then use the average value of the first amplitude value and the second amplitude value as the jack threshold;

If not, the second magnitude is used as the jack threshold.

Wherein, the first amplitude is the amplitude of the electrical signal of the controlled jack measured when the electrical appliance is not turned on after the plug of the electrical appliance is inserted into the controlled jack;

The second amplitude is the amplitude of the electrical signal of the controlled jack measured after the electrical appliance is turned on and then turned off;

The reason why the amplitude of the electrical signal of the controlled jack is measured twice is that the shutdown power of some electrical appliances after shutdown is much different from the shutdown power before startup. For example, some components still consume electricity after shutdown, but There is no power consumption before turning on, resulting in a large deviation in the power of the two shutdowns, because it is necessary to determine the shutdown power from normal operation to shutdown, and the first amplitude is the shutdown power that only supplies power to electrical appliances but is not turned on , based on this, the second amplitude needs to be selected as the jack threshold to further improve the jack threshold accuracy.

It should be noted that the deviation ratio between the first amplitude and the second amplitude is the ratio obtained by dividing the absolute value of the difference between the first amplitude and the second amplitude by the first amplitude, where Therefore, the threshold is selected in the form of ratio here, considering that there may be many different types of electrical appliances, and the shutdown power of different electrical appliances is different, so the difference between the two measurement results is allowed to be slightly different. In the case of comparing with the above-mentioned deviation ratio, when the electrical appliance is replaced, the preset ratio threshold does not need to be reset.

The jack threshold is determined by the above method, which improves the accuracy of the jack threshold. A specific example will be used to describe in detail below.

Specifically, the method for determining the jack threshold is as follows:

First, select the setting command, which can be sent by the mobile terminal or selected on the control panel. After receiving the setting command, the single-chip microcomputer will prompt to enter the jack threshold setting state through the display screen or the mobile terminal, and enter the confirmation plug-in state. The hole threshold value program prompts the user to set the electrical appliance on the jack whose jack threshold value is to be determined to the shutdown state, automatically detects the circuit state of the jack, and calculates the shutdown power at this time, that is, the first amplitude.

Specifically, the specific method for determining the above-mentioned first amplitude value is: after the single-chip microcomputer waits for 15 seconds, the voltage and current detection module starts to detect the state of the jack circuit, and calculates the effective measurement power (between 50 and 150) within 100 seconds. The average value determines the shutdown power, wherein, in the calculation process, the data with an error greater than 30% from the average value of the adjacent ten measurement results is regarded as invalid data, and the invalid data is discarded. According to the above, multiple acquisitions are used The method of shutting down the power and removing the abnormal data determines the shutting down power, which is the first amplitude, which improves the accuracy of the data.

Then, the user is prompted to set the electrical appliance on the jack whose jack threshold value is to be determined to the power-on state, automatically detects the circuit state of the jack, and calculates the power-on power at this time.

Specifically, the specific method for determining the above power-on power is: after the single-chip microcomputer waits for 30 seconds, the voltage and current detection module starts to detect the state of the jack circuit, and determines by calculating the average value of the measured power (between 50 and 150) within 3 minutes. The starting power of the electrical appliance.

Finally, the user is prompted to set the electrical appliance on the jack whose threshold value is to be determined to the shutdown state again, automatically detects the circuit status of the jack, and calculates the shutdown power at this time, that is, the second amplitude;

Specifically, the specific method for determining the above-mentioned second amplitude value is: after the single-chip microcomputer waits for one minute, the voltage and current detection module starts to detect the state of the jack circuit, and calculates the effective measured power (between 50 and 150) within 100 seconds. The average value determines the shutdown power, wherein, in the calculation process, the data with an error greater than 30% from the average value of the adjacent ten measurement results is regarded as invalid data, and the invalid data is discarded. According to the above, multiple acquisitions are used The method of shutting down the power and removing the abnormal data determines the shutting down power, that is, the second amplitude, which improves the accuracy of the data.

Comparing the relationship between the deviation ratio of the first amplitude value and the second amplitude value and the preset ratio threshold value, and then determining the jack threshold value, and storing the jack threshold value in a corresponding storage unit.

Specifically, taking the preset ratio threshold of 5% as an example, when the deviation threshold is less than 5%, it means that the power deviation between the two measurements is small, and the average value of the first amplitude and the second amplitude is taken as the jack threshold; When the deviation threshold is greater than 5%, it means that the power deviation between the two measurements is large, which may be due to the difference between the shutdown power of some electrical appliances after shutdown and the shutdown power before startup. There is no power consumption before, resulting in a large deviation in the power of the two shutdowns. Since it is necessary to determine the shutdown power that changes from normal operation to the shutdown state, and the first amplitude is the shutdown power that only supplies power to electrical appliances but is not turned on. Based on this, it is necessary to select the second amplitude value as the jack threshold to further improve the accuracy of the jack threshold.

It should be noted that, the method in the embodiment of the present invention can control the programs of each socket to run independently at the same time without interfering with each other through the writing of the single-chip microcomputer program or the development of a multi-threaded simultaneous working program, so as to realize the independent control of multiple sockets, which need to be determined separately The jack threshold of each electrical appliance can be determined in the same way. Compared with the existing method that can only pre-set the jack threshold for a specific electrical appliance, this method improves the accuracy of the jack threshold , at the same time, when the electrical appliance on the socket is replaced, considering that the shutdown power of different electrical appliances is different, after the user chooses to enter the setting state again, the socket threshold value of the new electrical appliance will be automatically detected, and the result will be used as the preset jack threshold.

In addition, when determining the threshold value of the jack, it should be determined according to the working state of the electrical appliance that needs to be automatically powered off. For example, the computer corresponds to the shutdown threshold, and the remote control TV, air conditioner, etc. correspond to the standby threshold, which is the power after the remote control is turned off. The setting can ensure that the power supply is automatically cut off after the TV or the air conditioner is turned off by the remote controller at night, thereby avoiding the standby power consumption of the TV or the air conditioner and other electrical appliances, and simultaneously reducing the probability of accidents during standby. In addition, for a computer, it is possible to distinguish between a shutdown state and a standby state, and it is possible to solve the problem of accidental power-off of electrical appliances in the standby state.

The method provided by this embodiment can realize automatic power-off, especially now that electrical appliances are becoming more and more intelligent, and many electrical appliances are equipped with remote controls. On the one hand, it brings certain convenience to people’s life and solves the On the other hand, it improves safety and prolongs the service life of electrical appliances.

Through step S102, the judging unit performs a comparison action to judge whether the amplitude of the current electrical signal of the controlled socket where the electrical consumer is located obtained in step S101 is greater than the threshold of the socket.

Step S103: If not, control the controlled socket where the electrical consumer is located to be powered off.

According to the judgment result of the above step S102, when the amplitude of the current electric signal of the controlled jack where the electrical appliance is located is less than or equal to the threshold value of the jack, it means that the electrical appliance is in the shutdown state, and step S103 is executed to automatically control the electrical appliance where the electrical appliance is located. The controlled jack is powered off, and the power supply to the appliance is stopped.

In the method for controlling the working state of the jack provided by the embodiment of the present invention, the amplitude of the electrical signal of the controlled jack where the electrical appliance is located is obtained, and the amplitude is compared with the pre-stored jack threshold. When the value is less than or equal to the threshold value of the jack, it means that the electrical appliance is in the shutdown state, and then controls the automatic power-off of the jack where the electrical appliance is located, and automatically cuts off the power of the jack where the electrical appliance is located. The problem of power consumption due to the failure to cut off the main power supply in the state, and prolong the service life of the electrical appliances, and improve the safety at the same time.

Considering that if you want to restart the socket, you need to open it manually, but generally in the family or office, the socket is placed in a place that is not easy to reach, and the manual switch is very inconvenient. In order to improve the usability, an implementation provided by the present invention The example also includes steps:

If the wireless turn-on signal or the voice-activated turn-on signal is obtained, the steps described in the step are performed to obtain the amplitude of the electrical signal of the controlled socket where the electrical appliance is located.

The wireless signal can be a wifi signal, or a bluetooth signal, or other wireless signals. within the scope of protection.

In addition, the method can also use the voice control signal to control the power supply to the single-chip microcomputer, thereby improving the ease of use and scope of application of the method.

Or the user can monitor the company's electrical appliances in real time at home to realize remote query and remote control. If they forget to turn off the electrical appliances (such as computers) after get off work or detect that the computers are in normal operation, it means that the computers may be used by others at this time. , which can be turned off by remote control.
