The voice control system includes an audio collection device 10, a voice recognition device 20, a detection device 30, a prompt device 40, and a logic control circuit 50.

 Its towel:

The audio collection device 10 is for receiving voice information. Users can say what they want to do around the voice control system, such as "Enter Cooling Mode", "Enter Heating Mode", "Increase Air Volume", "Reduce Air Volume", "Enhance Temperature", "Drop The low temperature ",""airconditioning","off air conditioning", etc., as long as the user can output commands through the control panel and the remote control, can be spoken by voice. In practice, the audio collection device 10 can be a microphone, or Other devices with integrated microphones.

 The voice recognition device 20 is connected to the audio collection device 10 for matching the voice information in the form of a telecommunication number obtained from the audio collection device 10 with a pre-stored command, and outputs a corresponding command to the logic control circuit 50. This command is a form that the air conditioning master control system can recognize. In the implementation, the voice recognition device 20 is mainly composed of an audio processing chip and an instruction database. The instruction database stores keywords and corresponding instructions, and the audio processing chip extracts keywords in the voice information, and then searches the instruction database for the corresponding keyword. The instruction outputs the instruction.

 The detecting device 30 is disposed indoors for detecting parameters of the indoor air, and outputs the detected parameter values to the logic control circuit 50.

 The prompting device 40 is connected to the logic control circuit 50 and can be correspondingly prompted under the control of the logic control circuit 50.

 The logic control circuit 50 is connected to the voice recognition device 20, the detecting device 30, the prompting device 40, and the main control system of the air conditioner (not shown). The logic control circuit 50 outputs the command acquired from the voice recognition device 20 to the main control system of the air conditioner. When the logic control circuit 50 determines that the parameter value acquired from the detecting device 30 is greater than the corresponding parameter threshold, the control prompt device 40 outputs the corresponding Tips.

 According to the voice control system of the air conditioner disclosed by the present invention, the user can speak the operation to be performed on the voice control system side, and the voice control system processes the valid voice information into a signal recognizable by the air conditioning main control system, and then transmits the signal to the air conditioner. The main control system allows the user to control the air conditioner. At the same time, the voice control system also detects the parameters of the indoor air in real time, and prompts the user to perform corresponding operations when the indoor air parameter value exceeds the corresponding parameter threshold.

 In practice, the logic control circuit 50 in the voice control system can be connected to the main control system of the air conditioner via a cable. Due to the limitation of the cable, the process of the user moving the voice control system may not be convenient. To solve this problem, the first communication interface 60 is further set in the voice control system, as shown in FIG.

The logic control circuit 50 outputs a dust-removal prompt when the dust value acquired from the dust sensor 301 is greater than the first dust threshold.

 After the voice control system outputs the dust removal prompt, the user can speak the corresponding voice information on the voice control system side to control the air conditioner to perform the dust removal operation. However, in practical applications, the user may not notice that the voice control system outputs a dust-removing prompt, which may cause physical damage when the user is in an environment with excessive dust for a long time. Therefore, the voice control system shown in Figure 2 can be improved, specifically:

 The logic control circuit 50 generates a dust removal control if a dust removal control instruction indicating that the air conditioner performs the dust removal operation is not acquired from the voice recognition device 20 within a preset time (for example, 30 seconds to 60 seconds) after the control prompting device 40 outputs the dust removal prompt. After the instruction, the dust removal control command is transmitted to the main control system of the air conditioner through the first communication interface 60 to control the air conditioner to open the internal dust removal device or the external controllable dust removal device to perform the dust removal operation.

 When the dust removal device is not provided in the air conditioner, and the air conditioner does not have a dust removal device controlled by the main control system of the air conditioner, the logic control circuit 50 in the voice control system may be connected to the external dust removal device. The dust removing device may be an air purifier or a ventilating device. The logic control circuit 50 controls the dust removing device to be turned on when the dust value obtained from the dust sensor 301 is greater than the first dust threshold, and controls the dust removing device to be turned off when the dust value obtained from the dust sensor 301 is less than the second dust threshold. .

 Its towel:

 The audio collection device 10 is for receiving voice information.

The voice recognition device 20 is connected to the audio collection device 10 for the telecommunication obtained from the audio collection device 10. The voice information in the form of a number is matched with the pre-stored command, and the corresponding command is output to the logic control circuit 60. This command is a form that the air conditioning master control system can recognize.

The first communication interface 60 and the logic control circuit 50 are wired, and the first communication interface 60 and the second communication interface are wirelessly connected. The second communication interface in the air-conditioned master control system is an existing communication interface adapted to the remote controller. In the implementation, the first communication interface 40 and the second communication interface may use an infrared transceiver module, a radio frequency module, a bluetooth module or a ZigBee module.

 The prompting device 40 is connected to the logic control circuit 50 and can be correspondingly prompted under the control of the logic control circuit 50.

 The logic control circuit 50 is connected to the voice recognition device 20, the dust sensor 301, the humidity sensor 302, the first communication interface 60, and the prompting device 40, respectively. The logic control circuit 50 outputs the command acquired from the voice recognition device 20 to the main control system of the air conditioner through the first communication interface 60, and the logic control circuit 50 determines that the dust value acquired by the dust sensor 301 is greater than the first dust threshold. The control prompting device 40 outputs a dust removal prompt. When the logic control circuit 50 determines that the humidity value acquired by the humidity sensor 302 is greater than the humidity threshold, the control prompting device 40 outputs a dehumidification prompt.

 According to the voice control system of the air conditioner disclosed above, the user can say the operation to be performed on the voice control system side, and the voice control system processes the valid voice information into a signal recognizable by the air conditioner's master control system, and then transmits the signal to the air conditioner's master control system. The air conditioning main control system allows the user to control the air conditioner. At the same time, the voice control system collects the dust content in the indoor air and the humidity of the indoor air in real time. When the dust content exceeds the first dust threshold, the user is prompted to perform the dust removal operation, and when the humidity of the air exceeds the humidity threshold, the user is prompted to perform the dust removal operation.

When the logic control circuit 50 controls the prompting device 40 to output a dehumidification prompt, the LED in the prompting device 40 for instructing the dehumidifying operation is illuminated, such as the blue LED being illuminated.

 Of course, the prompting device 40 can also be composed of a color-changing LED and a corresponding driving circuit. When different prompting information is output, the control LEDs exhibit different colors.

When the logic control circuit 50 controls the prompting device 40 to output a dehumidification prompt, the LED is adjusted to indicate the color for performing the dehumidification operation, such as adjusting the LED to blue.

 The present invention also discloses a control method of an air conditioning system including an air conditioner and a voice control system as described hereinbefore. The main control system of the air conditioner includes a second communication interface, a main controller, a second voice output module, and an audio playback device, and the structure thereof is as shown in FIG. The control method is shown in Figure 5, including:

 Step S101: The voice recognition device matches the voice information received by the audio collection device with the pre-stored instruction, and outputs a corresponding instruction.

 The user speaks the operation to be performed around the audio collection device in the voice control system, such as entering the cooling mode.

"Enter heating mode", "Increase air volume", "Reduce air volume", "Improve temperature", "Reduced temperature", "Open air conditioner", "Off air conditioner", etc., as long as the user can output through the control panel and remote control The instructions can be spoken in the form of voice. The voice recognition device matches the voice information in the form of an electrical signal obtained from the audio collection device with the pre-stored command, and inputs The corresponding instruction is sent to the logic control circuit.

 Step S102: The logic control circuit outputs an instruction acquired from the voice recognition device to the main controller of the air conditioning main control system.

 It should be noted that when the logic control circuit is connected to the main controller in the air conditioning main control system through the cable, the logic control circuit outputs the obtained instruction directly to the main controller through the cable. When the voice control system further includes the first communication interface, the logic control circuit outputs the command acquired from the voice recognition device through the first communication interface. After the logic control circuit outputs the command output by the voice recognition device through the first communication interface, the second communication interface in the air conditioning main control system can receive the command outputted by the first communication interface matched with the first communication interface.

 The commands transmitted by the voice control system to the air conditioning master control system include control commands and acknowledgement operation commands. The control instructions contain the contents of the operation that the air conditioner will perform. The confirmation operation instruction is used to instruct the main controller to control the operation corresponding to the control command received before the air conditioner is executed.

 Step S201: The main controller acquires an instruction output by the logic control circuit.

 Step S202: When the received command is a control command, the main controller controls the second voice output module to determine a voice signal corresponding to the control command, and then outputs the voice signal by the audio playback device.

 The command received by the air conditioning master control system from the voice control system is a control command or a confirmation operation command. When the main controller determines that the received command is a control command, the second voice output module is configured to search for a voice signal corresponding to the control command, and the second voice output module obtains the control command by using a correspondence between the pre-stored control command and the voice signal. The corresponding speech signal is then output by the audio playback device. The voice signal output by the audio playback device is used as a feedback signal operated by the user. When the user hears the voice signal played by the audio playback device, if the operation is confirmed to be performed, the confirmation message is input through the voice control system within a preset time, for example, "confirm" or a similar statement. The voice control system processes the natural statement confirmed by the characterization as a confirmation operation command and transmits it to the main control system of the air conditioner.

 Step S203: The main controller determines whether a confirmation operation command transmitted by the voice control system is received within a preset time after the audio playback device outputs the voice signal, and if yes, step S204 is performed.

 Step S204: Control the air conditioner to perform an operation corresponding to the control instruction.

When the main controller in the main control system of the air conditioner determines that the confirmation operation command transmitted by the voice control system is received within a preset time after the audio playback device outputs the voice signal, the control command received before the execution of the air conditioner is controlled Operation. For example: Control the air conditioner to enter the cooling mode, control the air conditioner to enter the heating mode, increase the air volume of the air conditioner, and reduce the air volume of the air supply.

 At the same time, the voice control system also performs the process shown in Figure 6, including:

 Step S103: The logic control circuit acquires a parameter value of the indoor air detected by the detecting device.

 Step S104: The logic control circuit compares the parameter values of the indoor air with the corresponding parameter thresholds. When the parameter value of the indoor air is greater than the corresponding parameter threshold, step S105 is performed.

 Step S105: The logic control circuit controls the prompting device to output a corresponding prompt.

 It should be noted that the execution sequence of the flow shown in FIG. 5 and the flow shown in FIG. 6 is not limited, and there is no necessary sequential execution sequence, and the two may be executed separately at different times or simultaneously. For example, the voice control system may perform the operation of detecting the indoor space air parameter periodically or irregularly, and then perform step S104 to determine whether or not to output a corresponding prompt. In this process, if the user outputs valid voice information, step S101 and subsequent steps are simultaneously performed.

 According to the control method of the air conditioning system disclosed by the present invention, the user can say the operation to be performed on the voice control system side, and the voice control system processes the valid voice information into a signal recognizable by the air conditioning main control system, and then transmits the signal to the air conditioner. After receiving the control command, the main control system of the air conditioner outputs a voice signal corresponding to the control command through the audio playback device. After the user hears the voice signal, if the user confirms that the operation is performed, the preset needs to be preset. The operation command is confirmed by the voice control system input time. This allows the user to perform voice control on the air conditioner, and only controls the air conditioner to perform the corresponding operation after the user inputs the confirmation operation instruction, thereby avoiding the problem that the user utters an inappropriate statement and causes the air conditioner to perform the corresponding improper operation, thereby avoiding the occurrence of the problem. The air conditioner performs different operations multiple times in a short period of time to avoid damage to the air conditioner. At the same time, the voice control system also collects indoor air parameters in real time. When the indoor air parameters exceed the corresponding thresholds, the user is prompted to perform corresponding operations, and the service is more humanized.

 In practice, the detecting device in the voice control system may include a dust sensor for detecting the dustiness of the indoor space, and then outputting the detected dust value to the logic control circuit. At this point, the voice control system performs the process shown in Figure 7, including:

 Step S1031: The logic control circuit acquires the dust value of the indoor space detected by the dust sensor.

Step S1041: The logic control circuit compares the dust value of the indoor space with the first dust threshold, when the dust of the indoor space When the degree value is greater than the first dustiness threshold, step S1051 is performed. The first dustiness threshold is a dustiness value that can cause adverse reactions in the human respiratory tract, and can be set by the user.

 Step S1051: The logic control circuit controls the prompting device to output a dusting prompt.

 In the flow shown in FIG. 7, after the logic control circuit obtains the dust value of the indoor space detected by the dust sensor in step S1031, step S1061 and step S1071 may be further included, as shown in FIG.

 Step S1061: The logic control circuit compares the dustiness value of the indoor space with the second dustiness threshold. When the dust of the indoor space is less than the second dustiness threshold, step S1071 is performed;

 Step S1071: The logic control circuit controls the prompting device to output an air qualification prompt.

 The second dustiness threshold is less than the first dustiness threshold.

 After acquiring the dust value of the indoor space, the logic control circuit not only compares whether the dust value is greater than the first dust threshold, but also determines whether the indoor air is harmful to the human body. At the same time, it is also compared whether the dust value is smaller than the second dust threshold, thereby determining whether the user is suitable to be indoors for a long time, and outputting a prompt to the user when the dust of the indoor air is qualified.

 The present invention further improves the flow shown in FIG. 7 and FIG. 8 in consideration of the fact that the user may ignore the dust-removing prompt output by the voice control system. Specifically, after performing the step S1051, the logic control circuit controls the prompting device to output the dust-removing prompt, the method further includes:

 The logic control circuit generates a dust removal control command and outputs it to the main controller if the dust removal control command is not received from the voice recognition device within a preset time after the control prompting device outputs the dust removal prompt.

 If the dustiness of the indoor space is greater than the first dustiness threshold, and the user does not input a statement for controlling the air conditioner to perform the dust removal operation within a preset time after the prompting device in the voice control system outputs the dust removal prompt, in order to avoid excessive The dust causes damage to the human body, and the logic control circuit generates a dust removal control command and transmits it to the main control system of the air conditioner. After receiving the confirmation operation command, the air conditioner starts the dust removal operation.

 It should be noted that when the command received by the main controller of the air conditioner is a dust removal control command, the air conditioner is controlled to perform operations corresponding to the control command, including:

 Determine the current operating status of the air conditioner.

When the air conditioner is in the cooling mode or heating mode, the dust control device is controlled to be turned on. When the air conditioner is in the standby state, the air conditioner is controlled to enter the air supply mode, and the dust removal device is controlled to be turned on. The dust removing device is an air purifier or a ventilating device built in the air conditioner, or an air purifier or a ventilating device connected to the main control system of the air conditioner.

 When the air conditioner is controlled to perform the dust removal operation corresponding to the dust removal control command, if the air conditioner is currently in the cooling mode or the heating mode, only the built-in or external dust removal device needs to be turned on at this time. If the air conditioner is in the standby state, turn on the dust removal device after you need to control the air conditioner to enter the air supply mode.
