Description
Technical Field
The invention relates to the technical field of intelligent equipment control, in particular to an intelligent socket control system, an intelligent socket control method, an intelligent socket control system and a storage medium.
Background
Technologies such as smart home, smart power, smart grid and the like realize wireless interconnection with household and civil appliances through a power system, complete intelligent management and control of household appliances, and try to provide a user with a careful service like a virtual manager. Smart sockets, as a common and universal entrance to household power supplies, are the most direct and convenient way to implement power supply and demand control. At present, various automatic and manual control sockets exist, such as light sensation, infrared induction, sound sensation, temperature sensation and other sensor control sockets, the technical schemes can realize that the household can construct various intelligent power control applications along with the change of the external environment and the scene requirements, but the control mode and the combination mechanical fixation, the global property and the real-time cooperativity are poor, the intelligent degree is lower, the user interactivity and the participation are weaker, and the defects of humanization, individuation and the like also exist.
Along with the popularization of intelligent terminals such as mobile phones, the intelligent socket and the mobile phone APP thereof are taken as hot solutions of the intelligent home, and the intelligent socket and the mobile phone APP thereof have important significance for meeting the increasing consumption demands of users. The wireless communication module of the intelligent socket can enable household appliances such as televisions, tablet computers and electric water heaters to be connected into a home network like WIFI. The smart socket APP is an interaction platform for a user to use a mobile phone and a socket. According to the different degree of participation of the user, the intelligent home solution based on the intelligent socket mainly comprises two types: the system comprises a shallow intelligent home solution depending on user decision and a deep intelligent home solution depending on data acquisition and analysis.
These solutions have the following drawbacks:
1) special APPs must be relied upon. Most smart sockets need to complete functions by means of special APPs provided by manufacturers, users need to use such APPs for initial configuration when using the sockets of this type for the first time, and in later use, the applications need to be frequently used for opening and closing operations of switches. Therefore, the method has the disadvantages of complicated configuration and dependence on special APP.
2) Depending on the network environment. Most of intelligent sockets need network environment support, and cannot work normally when 3/4G or WIFI are limited.
3) Depending on the accuracy of the keyword wake-up and speech recognition. Some smart sockets support user voice operation, but require keyword wake-up and rely on accuracy of voice recognition. In order to realize the voice operation function, the socket also generally needs the support of a mobile phone and special equipment, and the cost is high. In actual use, the problem of collected voice distortion caused by environmental noise and the distance between a user and a socket radio can cause the problem that a voice recognition function cannot normally function, and the problem that the user does not respond or operates mistakenly when sending a voice command occurs.
4) The voice recognition security is low. In the use process of the intelligent socket supporting the voice operation of the user, as long as the user can correctly speak the awakening word, the user can continue to send out the control command through the voice. Although such smart jacks support user-defined wake-up words, there is still a possibility that the wake-up words can be eavesdropped and leaked, and thus the method of controlling the jack using the user's voice is not highly secure.

Furthermore, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.
Referring to fig. 1, an embodiment of the present invention provides an intelligent socket control system, including:
the Bluetooth receiving module is used for receiving Bluetooth audio data sent by a user side and performing digital-to-analog conversion on the Bluetooth audio data to obtain a first analog audio signal;
the audio amplifier module is used for amplifying the first analog audio signal to obtain a second analog audio signal;
the comparator module is used for detecting whether the signal intensity of the second analog audio signal exceeds a preset intensity threshold value or not and generating a corresponding trigger signal according to a detection result;
and the relay module is used for controlling the relay to be switched on or switched off according to the trigger signal so as to control the on-off state of the intelligent socket.
Specifically, in the embodiment of the present invention, the bluetooth audio data is sent to the bluetooth receiving module inside the smart jack through the user side, the bluetooth receiving module performs digital-to-analog conversion on the received bluetooth audio data to obtain the analog audio signal, the audio amplifier module amplifies the intensity of the analog audio signal, the comparator module detects whether the signal intensity of the analog audio signal exceeds a preset intensity threshold, and finally the relay module controls the on-off state of the smart jack according to the detection result of the comparator module. Compared with the intelligent socket using voice recognition, the intelligent socket is controlled by transmitting audio data through Bluetooth, and a user can complete control without actually making a sound, so that the problems of no response, misoperation and the like caused by recognition failure possibly occurring in voice recognition are avoided, the voice command is ensured not to be intercepted manually, and the control safety of the intelligent socket is improved; in addition, the embodiment of the invention can realize low-cost and quick intelligent socket control without network connection or installation of a special APP, thereby improving the convenience of intelligent socket control.
As a further optional implementation, the bluetooth receiving module includes:
the identity authentication unit is used for performing identity authentication on the user side and performing Bluetooth connection with the user side passing the identity authentication;
the data receiving unit is used for receiving Bluetooth audio data sent by the user terminal, and the Bluetooth audio data comprises a preset audio file and a real-time voice fragment acquired by a microphone of the user terminal;
and the decoding unit is used for performing digital-to-analog conversion on the Bluetooth audio data and decoding to obtain a first analog audio signal.
Specifically, the bluetooth receiving module is used for receiving bluetooth audio data sent by the user side and performing digital-to-analog conversion on the audio data, and the user side stores the control command in the form of the audio data and sends the control command to the intelligent socket side in a bluetooth communication mode. Before receiving audio data of a user side, a Bluetooth receiving module firstly informs surrounding equipment of the existence of the Bluetooth receiving module through broadcasting, the user side requests to establish Bluetooth connection through broadcasting information of the Bluetooth receiving module, and after handshaking of a protocol layer is carried out, the Bluetooth connection between the user side and an intelligent socket end is successfully established, and then the Bluetooth audio data of the user side can be transmitted.
Optionally, the connection with the bluetooth receiving module needs to be authenticated for the user identity to improve security. Specifically, the connection request can be verified through a preset PIN code, or the connection request can be allowed through an active triggering action performed by the bluetooth receiving module, for example, whether to open the connection is determined by whether a connection allowing key on the smart socket is pressed down. The identity authentication only needs identity authentication when the user side is connected for the first time, after the authentication is passed, the identity information of the user side can be stored in a default trusty list of the Bluetooth receiving module, and then the user side can be automatically connected to the Bluetooth receiving module without authentication.
After the user side establishes transmission connection with the Bluetooth receiving module, the user side can transmit one section of Bluetooth audio data to the intelligent socket end in two modes: firstly, a section of audio data which can be decoded by a Bluetooth receiving module is transmitted to the Bluetooth audio receiving module through a Bluetooth file transmission protocol, for example, a section of audio file is transmitted to an intelligent socket for triggering through Bluetooth sharing in a file browser, and the section of audio file can be well preset and corresponds to a corresponding control instruction; secondly, audio data collected by a microphone of the user terminal is transmitted to the intelligent socket in real time through an audio transmission protocol, for example, after Bluetooth connection is matched, the microphone is called by using functions of 'WeChat voice' and the like, and then the audio data can be sent for controlling the intelligent socket by speaking on the microphone of the user terminal.
After the bluetooth receiving module successfully receives the bluetooth audio data of the user side, the bluetooth receiving module needs to decode and convert the digital signal of the section of audio data into an analog signal, and since the received audio data is a digital signal which is subjected to coding and compression, the instruction information of the user is received through the analog signal which can be used for describing sound wave information. Therefore, the bluetooth receiving module also needs to perform digital-to-analog conversion on the received audio data sent by the user side, and decode the audio data to obtain an analog signal acquired by the original user side for the function execution of the subsequent module.
The audio amplifier module is used for amplifying the analog audio signal decoded and converted by the Bluetooth receiving module. Specifically, the voltage value range of the analog signal at the output end of the bluetooth receiving module is limited by the chip process and the circuit design, and the analog signal obtained by analysis and conversion is often distorted due to uncontrollable factors such as electromagnetic interference and mutual interference between circuit layers which may exist in the surrounding environment. If the distortion phenomenon generates a signal oscillation whose amplitude is greater than the threshold signal strength preset by the comparator module, the subsequent analysis of the comparator module on the correct instruction information of the user is affected, so that the audio amplifier module is not only used for amplifying the signal, but also used for filtering interference and restoring the original analog signal characteristics of the user side.
As a further optional embodiment, the comparator module comprises:
the detection unit is used for detecting the signal intensity of the second analog audio signal at each moment;
the comparison unit is used for comparing the signal intensity at each moment with a preset intensity threshold value;
and the trigger unit is used for generating jump from a low level to a high level when the signal strength at a certain moment is greater than the strength threshold value, and transmitting the jump to the relay module as a trigger signal.
Specifically, after being processed by the bluetooth receiving module and the audio amplifier module, the obtained second analog audio signal is a continuously fluctuating audio signal. The comparator module is used for detecting whether the strength of the second analog audio signal exceeds a preset strength threshold value, if the signal strength of the analog signal exceeds the preset strength threshold value at a certain moment, a trigger unit of the comparator module generates a jump from low voltage to high voltage, and the jump is used as a trigger signal to be sent to the relay module for subsequent logic processing; and if the signal intensity of the whole second analog audio signal does not exceed the preset threshold value, the trigger unit does not generate voltage jump, the relay module is also kept unchanged, the workflow returns to the Bluetooth receiving module to wait for receiving new user side to send audio data, and a new workflow is executed.
The comparison unit comprises an adjustable resistor and a comparator, the positive pole of the power supply end of the comparator inputs power supply voltage, and the negative pole of the power supply end of the comparator is grounded. The comparator is provided with two input ends, namely a non-inverting input end and an inverting input end, the inverting input end of the comparator is connected with the adjustable resistor, and the non-inverting input end of the comparator is connected with the output end of the audio amplifier module.
The strength threshold of the comparison unit allows customization. Specifically, the voltage of the inverting input terminal of the comparator can be adjusted by adjusting a potentiometer knob of the comparator module or changing the resistance value of the adjustable resistor by using a programmable resistor module. The adjustable resistor can be a manual adjustable rheostat or a programmable adjustable resistor module. Optionally, the programmable resistance adjusting module may further perform resistance configuration by using the GAP to perform transmission parameters through a daemon running on the MCU of the bluetooth receiving module.
Fig. 2 is a schematic diagram illustrating the generation principle of the trigger signal, and it is assumed that the voltage value at the inverting input terminal of the comparator adjusted by the adjustable resistor is v, that is, the intensity threshold is v. A section of analog signal shown in fig. 2 is input to the non-inverting input end of the comparator, before the time t, the voltage value of the section of analog signal is smaller than V, the voltage value of the non-inverting input end of the comparator is smaller than the voltage value of the inverting input end, and the comparator outputs 0V; and in a period of time after the time t, the voltage value of the analog signal is greater than v, the voltage value of the non-inverting input end of the comparator is greater than the voltage value of the inverting input end, and the output end of the comparator generates a jump from low voltage to high voltage as a trigger signal and sends the jump to the relay module.
Further as an optional implementation manner, there are a plurality of comparator modules, the intensity thresholds of the plurality of comparator modules are different, and the plurality of comparator modules are configured to generate different trigger signals according to the signal intensity of the second analog audio signal.
In particular, multiple comparator modules may be used in parallel for multi-level command control purposes. When a plurality of comparator modules are connected in parallel, after the analog signals output by the audio amplifier module are received, the trigger threshold of each comparator module is adjustable, and the programmable logic controller of the subsequent relay module is matched, so that more precise control on the intelligent socket can be realized.
As a further optional embodiment, the relay module comprises:
the control unit is used for generating a state reversal operation instruction according to the trigger signal;
and the relay unit is used for executing the closing or opening of the relay according to the state reversal operation instruction.
Specifically, the relay module is used for receiving and processing a trigger signal sent by the comparator module and controlling the relay to be closed or opened. The relay module comprises a control unit and a relay unit, and specifically, when the comparator module detects that the peak intensity of an analog signal analyzed from the received audio signal is greater than the preset threshold intensity, the comparator module generates a jump from a low voltage to a high voltage as a trigger signal for controlling the state reversal of the relay. And after receiving the trigger signal of the state reversal, the control unit of the relay module executes the state reversal operation according to the internal logic.
If before the execution state reversal operation, the relay electromagnetic module is electrified, the internal electromagnet has a magnetic attraction switch because the relay module is electrified, the controlled power supply is electrified, and after the relay module receives the execution state reversal operation, the internal electromagnetic power is cut off, the magnetic attraction switch is disconnected, and the controlled power supply is cut off. Similarly, if the relay electromagnetic module is powered off before the reverse operation of the execution state, the internal electromagnet is powered off because the relay module is powered off and the magnetic attraction is disconnected, the controlled power supply is powered off, and after the relay module receives the reverse operation of the execution state, the internal electromagnetic electricity is powered on, the magnetic attraction switch is switched on, and the controlled power supply is powered on.
Specifically. When the control unit detects that the output end of the comparator module has low-to-high level modulation once, the controller records the jump and stores the jump into the corresponding trigger register, for example, the jump is stored as 1 on the corresponding trigger register, and finally, the relay controller outputs the control voltage to the relay according to the content on the trigger register, so as to control the on-off and the on-off of the relay.
Optionally, when the comparator module adopts a multi-stage parallel connection mode, if there are N stages of comparators, the trigger threshold of each stage of comparator is v1、v2、v3...vNThe result of whether each comparator generates a jump is stored in the trigger register. For example, after an 8-stage comparator processes a section of audio, the content of the trigger register of the controller of the relay module is 01011010, and the controller executes a corresponding control command according to the content of the trigger.
Further as an alternative embodiment, the control unit is only responsive to the first generated trigger signal when multiple trigger signals are generated for the same bluetooth audio data.
In particular, the control unit of the relay module may be configured in a single-workflow, single-trigger mode. When the bluetooth audio data is the user voice collected by the user-side microphone, a section of bluetooth audio may generate multiple low-voltage to high-voltage jumps after being analyzed by the comparator due to environmental noise or human factors, and the control unit of the relay module may adversely affect the control operation if performing multiple state inversions. Therefore, the control unit of the relay module can be configured to be in a single-working-flow single-trigger mode, and the relay module can only perform opening or closing operation once at most for a section of audio data.
Optionally, if the comparator modules are connected in parallel in multiple stages, the control unit of the relay module may adopt a programmable controller, which supports multiple trigger sources, and a logic control program of the programmable controller may be reprogrammed through the bluetooth receiving module, which is more flexible.
