Intelligent voice-activated infrared remote control appliance controller

This design relates to a voice-activated remote control device, which is applied to home appliances with an infrared remote control, and uses a non-specific speaker and voice recognition technology to realize the device design.

Nowadays, in home life, more and more electronic products are controlled by remote control. Because there are too many remote controls, sometimes it is not easy to find one out of many remote controls. Therefore, how to reduce the number of remote controllers, users can easily control a variety of electrical appliances, especially different types of electrical appliances, but also allows users to easily set up is needed.

There is a learning remote control on the market, which can be used to input the function keys commonly used in electronic products. A remote control can remotely control many electronic products. More advanced voice control can be used, but it is often necessary to record before training. It can only be used if it is used by your own voice control.

In this design, it is more convenient to design and process for the first recording and training, and to use the unspecified language and speech recognition technology to overcome this problem. It makes the voice control application more convenient and flexible in the control of the infrared remote control appliance. You can plan and design your own voice controller according to your own needs. In addition to your own use, other members of the home can also use it.

The main purpose of this design is to provide a home appliance that uses voice-activated infrared remote control to allow users to name home appliances and directly control home appliances. Another purpose of the design is to provide a smart and flexible setting interface, and the computer can be used to plan commands for sound control operations of specific home appliances, which can be easily set by the user. Another purpose of the design of the device is to design its own specific voice controller. In addition to its own use, other members of the home can also use the home appliance function that you want to control, and the mouth can be realized.

The design concept of the device can be directly inserted into the host of the home appliance, directly implementing the voice control application, or directly into the remote controller of the home appliance, directly speaking the function to be operated without necessarily pressing the remote controller. The entire device design includes the following features:

<6> You can use the infrared remote control of the home appliance and key input data to back up and archive the data, so that it can be used from time to time or for special purposes.

To achieve the above objectives, the device includes a voice control module, a single chip processor, a memory, a speaker, a microphone, several operation buttons, an infrared emitter and an infrared receiver, a proximity trigger sensor, and a computer connection interface. The voice control module includes an analog processing interface, including a voice input and output related analog circuit and an audio amplifier. Built-in preamplifier, automatic gain control (AGC), analog to digital conversion (ADC) and digital to analog conversion (DAC) interface, these circuits are used to simplify microphone recording and playback functions, module built-in synthesis Directly input text file, you can output voice, which is convenient for verifying the recognition result.

The voice control module has built-in voice recognition technology for non-specific speakers, and the voice to be recognized. This application controls the homework action command. After being loaded through the computer loading interface, it becomes a voice recognition comparison database, and the recognition function can be performed. . In the identification stage, the voice control module analyzes the voice signal recorded during the recognition, including voice cutting, feature parameter analysis and recognition comparison, and finally outputs the result to the single-chip processor for subsequent processing.

The infrared emitter and the infrared receiver are used to transmit and receive infrared signals, and the infrared emitter emits a control signal compatible with the original home appliance remote controller. The infrared receiver is used to learn the control signals emitted by the original home appliance remote control, and is used to design learning type voice control appliances. All the infrared signals received and learned are stored in non-volatile memory, and the data is still saved when the computer is turned off.

Designing a specific model of home appliances is to use infrared remote control fixed code transcoding technology, first analyze the commonly used button signal code on the home appliance remote control, such as the power on/off button, and then transcode the button signal code into the control program. The design learning model adopts the infrared remote control online learning technology. The user first learns the key signal codes commonly used on the remote controller one by one, learns the host, and transmits to verify the learning result, whether it can be started.

The important factor affecting the recognition rate in voice control applications is the quality of voice input. When the background noise is too high and noisy, it is usually not used. Therefore, the radio design is very important. This is related to the design of the microphone. The host has a non-directional condenser microphone. Radio.

The system is designed to use the computer connection (can use RS232 or USB) to upload or download functions, to update the necessary information, and make the system work. The related usage concepts are designed as follows:

<1> Home appliance voice control command and corresponding infrared emission signal control command file

With a control command file, the file name is CAP.TXT to define, the user can edit the content of the relevant voice control command to inform the host which name and relative action can be identified.

<2> Voice control host system adjustment parameters

For example, set the microphone gain and the output volume of the speaker.

<3>The voice controller controls the computer to operate the machine as a voice control

In addition to controlling the home appliance, the voice controller transmits the voice recognition result back to the computer, and can also use the computer as a voice control execution machine to execute a specific function program.

<4> The sound controller can be controlled by a computer to remotely control the home appliance action.

The sound controller is connected to the computer, and the computer can also control the emission of infrared signals to control the movement of the home appliance.

<5> Back up the infrared remote control button of the appliance and store it in the computer archive.

The infrared remote control of the home appliance can be used to archive the key input data, so that it can be used from time to time.

Since the voice controller has an infrared signal on-line learning function, the infrared remote control of the home appliance and the key input data can be transmitted back to the computer for backup and archiving of the data, so as to be needed from time to time. If the remote control is broken, or other factors can't work, you can try using a computer to control the startup. The remote control data backup archive can be divided into learning an infrared remote control button input data, or multiple infrared remote control button input data. For details, please refer to the implementation method for explanation.

If you choose to use a computer to transmit infrared signals, you can control home appliances that operate with an infrared remote control. The computer requires an application and an infrared signal source. There are two types:

<1>New appliance control application downloaded from the Internet

<2> Home appliance remote control button data backup file

The average user can do the application via a dedicated control program provided to the client standard. For users of special applications, you can also use the API (Application Program Interface) application programming interface built in the system to implement special functions with the familiar code.

In order to enable your review board to better understand the technical content of this design, some preferred embodiments are described below.

1 is a schematic diagram of the appearance of a voice-activated infrared remote control home appliance controller. The appearance of the voice controller includes an indicator light 14, an operation button 1 21, an operation button 2 22, a speaker l5, an internal microphone 16, a computer connection interface 17, a power source 40, and an infrared emitter 31. The infrared receiver 32 and the proximity trigger sensor 33.

2 is a block diagram of the internal structure of the voice control host. The main control unit includes a single chip 11, a voice control module 12, a memory 13, a microphone 16, a speaker 15, an infrared emitter 31, an infrared receiver 32, a proximity trigger sensor 33, and a computer. Connection interface 17.

The operation button 1 21 is a command to view the command, and can play which commands have been loaded. This is a view function of the design. After the user presses the operation button, the host will pass the loaded commands one by one through the speaker. 15 Say it, use it as a reminder. The operation button 2 22 is a voice control button, which can activate the voice control function and start to speak commands to control the home appliance movement. At this time, the indicator light 14 will light up, and the host will make a "beep" sound to prompt the user to start the next command. If the command is spoken, the system will recognize the correct signal and the infrared emitter 31 will send out the signal.

When the voice is controlled, it is a little inconvenient to press the button. In the design, the proximity trigger sensor 33 is added. When the user approaches the host by about 10 cm, the system also detects that the user wants to perform voice control, and then issues "". Sound, the prompt can be voiced, so you can voice control without pressing the button. The voice controller has a non-directional capacitive microphone 16 built in. When the sound is controlled in a noisy environment, as long as it is within one meter of the machine, the command can be started.

Figure 3 is a schematic diagram of the voice controller setting. The system is designed to use the computer connection interface 17 (can use RS232 or USB) to upload or download functions, to update the necessary information to make the system work. When the user first uses the voice control, he does not know which commands have been loaded in the system. Therefore, the voice command database and the relative infrared signal need to be processed. The user can use the paper processor on the computer 60 to edit the game. It is transmitted to the machine through the control program. The relevant voice command format is as follows: Format 1: System command, used to control the host to leave the continuous recognition mode. Voice command Q format 2: Online learning needs to set the voice command L immediately [set immediately one by one in a limited time] DdL [set immediately one by one in a limited time]: Infrared signal that is learned immediately, within a limited time (for example, within 10 seconds) Individually set the learning signal Dd: delay time unit setting after each group of infrared signals is transmitted d: delay parameter 1~9 means 1~9 seconds According to the above description, design a command file, the file name is CAP.TXT, The content is as follows: leave the Q TV L D2 fan L

<img file="TWM348993U_D0001.tif" />

Line 1: Define the voice command that says to leave the continuous recognition mode as "Leave"

Line 2: When "TV" is spoken, the system uses the online learning infrared signal to transmit. If there are more than 2 groups of signals learned online, each group of signals will be delayed for 2 seconds before transmitting the next set of signals. Since the command is to control the TV to be turned on, the power button signal of the remote controller 51 (this is the TV remote controller) of the home appliance is learned to the corresponding position of the command. The learning action is to point the home appliance remote controller 51 toward the infrared receiver 32 of the host computer 10, and press the button to learn the data.

Line 3: When the "fan" is spoken, the system uses the infrared signal of the online learning to transmit. Since the command is to control the fan to open, the power button signal of the fan remote controller needs to be learned to the corresponding position of the command.

The user can set the command of how to voice control the home appliance, and set it in advance through the computer. After the remote controller is set, the home appliance can be voice-activated. Because it is a self-set voice command, it is generally not easy to forget. If you forget it for a while, you can press the command button and the system will say the command.

If the host has loaded the voice command file, you can do the action of the remote controller to learn immediately. Press 1 21 (listening function/setting function) on the main unit. The main functions are as follows: press to release: listen to the current voice command content and press and hold more than 1 Release after seconds: The system enters the remote control signal learning mode and sets the remote control signal corresponding to the voice content just heard.

Take "television" in the voice command file as an example, how the TV works, as explained below. TV L D2 Description: Say "TV", the system uses the infrared signal that is learned immediately to transmit.

When the button 1 21 is pressed, when the system says "TV", and then press and hold the button 1 21 until the indicator light 14 lights up, it is necessary to set the remote control signal corresponding to "TV". At this point, the TV remote control is facing the host, press the remote control power button, when the host receives the signal, the indicator light 14 will flash, the watch receives the remote control signal. You can also learn other functions at the same time, up to 5 groups of signals, this is the multi-signal input function. Press the remote control related button repeatedly until the relevant motion remote control signal input is completed. The effective time is about 10 seconds, and at most 5 groups of signals can be input continuously. When the time is up, it will automatically leave the setting mode.

When the TV is connected to the audio, the speaker will be turned on, or other integrated applications, multiple signal input functions will come in handy, in addition to learning the TV remote control power button, the audio remote control power button can also learn together, when said Out of "television", the host 10 acts as follows:

&lt;1&gt;Send the TV remote control power button signal to turn on the TV

&lt;2&gt; Re-transmit the audio button of the audio remote control and turn on the sound. Therefore, it is not necessary to find 2 remote controllers, find the position of the power button, and press 2 buttons. Just need to approach the host with your hand, and intuitively say "television", a good TV picture and sound effects are immediately presented, very convenient.

Since the infrared remote control has a wired learning function, the infrared remote control 51 of the home appliance can be transmitted back to the computer 60 for data backup and archiving, so that it can be used from time to time. The remote control data backup archive can be divided into learning an infrared remote control button input data, or multiple infrared remote control button input data.

The computer 60 needs to execute the infrared remote control button learning program, LIRX.EXE. After the execution, the screen appears as shown in Figure 4. There are the following computer 60 keyboard commands: ESC key: End program execution Blank key: Learn an infrared data code and automatically archive it as TE. IRT/t key: Launch the infrared signal data just learned L/l key: Learn multiple infrared data codes and automatically archive them as TE. IRX first connects the host 10 to the computer 60, and learns to back up an infrared remote control button input data. The steps are as follows:

&lt;1&gt; Execute the standard learning application LIRX.EXE.

&lt;2&gt; Press the computer 60 keyboard empty table button to learn an infrared remote control button input data.

&lt;3&gt; Press the button related to the remote controller 51. When the host 10 receives the signal, the indicator light 14 will flash to indicate that the remote controller signal has been received.

&lt;4&gt; Press the T key of the computer 60 keyboard to transmit the test signal, and then transmit the infrared signal that has just been learned to see if the home appliance can operate to confirm that the learned signal is valid.

&lt;5&gt; Infrared code learning function will be automatically archived as TE. IR. Just change the file name, such as t1. IR, it can be used for multiple remote control button backup data.

Learn to back up multiple infrared remote control buttons to input data at one time. The steps are as follows:

&lt;1&gt; Execute the standard learning application LIRX.EXE.

&lt;2&gt; Press the L key of the computer 60 keyboard, input and learn the input data of multiple infrared remote control buttons.

&lt;3&gt; Press the button related to the remote controller 51. When the host 10 receives the signal, the indicator light 14 will flash to indicate that the remote controller signal has been received.

&lt;4&gt; Press the T key of the computer 60 keyboard to transmit the infrared signal that has just been learned, to see if the appliance can operate, and confirm that the learned signal is valid.

&lt;5&gt; Press the L key of the computer 60 keyboard to continue learning the data of the next remote control button. If you press the ESC key, you will finish learning the next remote control button data and automatically archive it as TE. IRX, just change the file name, such as t1 IRX can be used to back up data from multiple remote controls.

&lt;6&gt; Please remember the signal action of learning in order. This is related to the application that will be taken out in the future.

FIG. 5 is a schematic diagram of the use of the voice controller 10. In this case, it is not necessary to connect the computer 60 to directly control the voice. General users can have voice control in the following ways:

Method 1: Operation button 2 22 voice button.

Mode 2: With the hand approaching the host 10, the host emits a "beep" sound, and can be voice-activated without pressing a button.

Mode 3: After pressing the button 2 voice-activated start button for more than 2 seconds, the host enters the continuous recognition mode.

When the host 10 enters the continuous recognition mode, the indicator light 14 will illuminate to indicate that the voice control is accepted. The indicator light 14 will be off, indicating that the command is started, and the host does not accept any voice commands. When the indicator light 14 lights up again, it indicates that voice control can be accepted. This action continues until the host 10 receives the "leave" command and leaves the continuous recognition mode.

The continuous recognition mode allows the operator to voice control without having to press a button. The operator does not need to be close to the host to voice control. The "Leave" command is a system-defined system voice command that is used to control the host to leave the continuous recognition mode. Therefore, the user only needs to set the control command in advance, and once the continuous recognition mode is started, the user does not have to operate by hand at all, and the voice can be continuously controlled. Connecting to computer 60 can also be used for other applications. The related design is as follows:

Application 1: The related application is executed, and the sound controller 10 controls the operation of the computer 60.

The voice control recognition result does not do the home appliance 50 control action, and the result is transmitted back to the computer 60, and the computer 60 is used as a voice control execution machine, which can be playing a KTV video file, playing CD music or MP3, or executing a special application, such as using The paper processor to edit the file. The average user can control through the application provided to the client standard. For special application users, you can use the built-in API (Application ProgramInterface) application design interface to implement special functions in general code. The API program shortcode function is as follows: function run ("voice command", full computer file path, 'control parameter'); example run ("paper processing", "c:\windows\system32\notepad.exe", 'X '); Say "document processing", it will open the "Notepad" program on the computer 60 for word processing.

Application 2: The API application design interface is designed to design a new diversified application that emits infrared signals by the computer 60 in a common programming.

If you choose to use the computer 60 to transmit signals, the average user can do the application through a dedicated program provided to the client standard. For users of special applications, you can design your own style special function application through the system's built-in API application design interface and the general programming interface.

The computer 60 controls the transmission signal and transmits a single group of signals at a time. The API program short code function is as follows: function ir_tx1 (infrared emission signal file name); example ir_tx1 ("t1. IR"); program function is to read infrared emission signal file T1. IR, the data is transmitted to the host 10, and the signal is transmitted.

The computer 60 controls the transmission signal, transmits multiple sets of signals, and downloads all the signals to the host 10 at a time. The API shortcode function is as follows: function ir_load (multiple sets of infrared emission signal file names); example ir_load("t1. IRX "); The program function reads multiple sets of signal files t1. IRX, and transfers multiple pieces of data to the host 10 at a time.

Specify which group of signals to transmit. The API shortcode function is as follows: function ir_tx (which group of infrared signals); example ir_tX(3); program function is to send out the signal of group 3, so the user needs to remember the original It is necessary to learn the behavior of each group of signals in order to control the movement of the appliance correctly.

6 is a schematic diagram of the use of the voice controller 10 in combination with another universal multi-function remote controller 52 to control the operation of the home appliance 50. The function design purpose does not require the computer 60, and the infrared remote control 51 key backup data of the home appliance can be taken out and used. Further, the remote control appliance 50 operates, and if the original home appliance remote controller 51 is damaged. At this time, the voice controller main unit 10 becomes a learning type remote controller, and the related control program is integrated to perform complicated control.

The remote controller controls the voice controller to transmit signals. The design method is as follows:

&lt;1&gt; A plurality of home appliance remote controller data are transmitted to the host computer 10 at a time via the control program.

&lt;2&gt; Set a universal multi-function remote control 52 to a fixed model. If it is set, you can remotely control the remote control of the Datong TV.

&lt;3&gt; The infrared receiver 32 of the voice control controller 10 can receive and decode the signal of the universal remote controller 52.

&lt;4&gt; When the universal remote controller 52 presses a certain button, the voice control controller 10 can decode and transmit the corresponding home appliance remote controller data, thereby controlling the home appliance 50 operation.

&lt;5&gt; The user needs to remember why each group of signal actions that were originally learned in order, and corresponding to a certain button of the universal remote controller 52, can correctly control the operation of the home appliance 50.

Due to the popularity of computers, the living room in the home often puts a computer to access the Internet for information, so it can use the computer to control the movement of home appliances, and can also create a lot of new gameplay and business opportunities. FIG. 7 is a schematic diagram of a graphical interface for controlling a plurality of home appliances 50 in a living room by using a computer 60 to connect a host computer 10. When the mouse is operated on a computer, an infrared signal can be emitted to control the movement of the home appliance. In this case, a computer-specific appliance control program and an infrared control code for each appliance are required, and the appliance control program can be generally provided to the consumer for downloading and using via the network 70. Special home appliance infrared control code, users can get the signal through the standard learning application LIRX. EXE introduced above.

The operation is as follows:

&lt;1&gt; The computer 60 is connected to the network 70, and the computer-side home appliance control program is downloaded.
