Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Fig. 1 is a flowchart of a voice control method according to an embodiment of the present invention. In this embodiment, relate to speech equipment and intelligent air conditioner both ends, wherein, speech equipment and intelligent air conditioner accessible serial ports hardware connection also can be connected through other wireless modes such as wifi. As shown in fig. 1, the method is applied to a smart air conditioner, and includes the following steps S11-S13:
and step S11, receiving a control command sent by the voice device, wherein the control command is obtained by the voice device by encoding the voice information input by the user according to a preset command format.
The voice device can be any device with a voice recognition function, such as a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant and the like.
The step of the voice device transmitting the control command to the smart air conditioner includes steps S21-S23 shown in fig. 2:
in step S21, the voice information input by the user is received.
And step S22, coding the voice information input by the user according to the preset command format to obtain the control command.
Before the speech equipment encodes the speech information, the speech information needs to be recognized firstly, and the specific recognition mode is as follows: searching and matching can be carried out according to the acoustic model and the language model which are trained in advance, and the acoustic model and the language model are converted into the text content corresponding to the voice information. In the process, in order to improve the accuracy of voice recognition, the voice information reaching a certain decibel value can be set and received, and the voice information with a smaller decibel value is directly filtered. The voice device can perform online recognition and can also perform offline recognition. For example, the speech device first performs online recognition on speech information, that is, performs online recognition using data such as a language database and an acoustic model on the network side, and performs offline recognition when a recognition result is not obtained within a certain period of time (for example, 5 seconds). Since the specific speech recognition process is the prior art, it is not described in detail.
And step S23, sending the coded control command to the intelligent air conditioner.
And step S12, decoding the control command according to the preset command format to obtain the effective information carried in the control command.
In step S13, an operation corresponding to the valid information is performed.
By adopting the technical scheme provided by the embodiment of the invention, the effect that the user controls the air conditioner in a voice input mode is realized by receiving the control command which is sent by the voice equipment and obtained by encoding the voice information input by the user according to the preset command format, decoding the control command according to the preset command format and further executing corresponding operation.
In one embodiment, the control command includes N bytes, each byte corresponds to an encoding value, the encoding value includes an identification encoding value, a control type encoding value, a control parameter encoding value, or a check code of the intelligent air conditioner, and N is a positive integer greater than 1.
Table 1 is a lookup table of bytes and encoded values and the meaning of each encoded value in a preset command format in a specific embodiment, where N is 8.
In table 1, byte 0 is a fixed value, meaning a sync header, which corresponds to a start symbol of a control command and has a reset function.
Byte 1 records the ID of the intelligent air conditioner, namely the identification of the intelligent air conditioner, each intelligent air conditioner has a unique identification, and related information can be accurately transmitted between the voice equipment and the intelligent air conditioner according to the identification. The identity mark can be represented by information such as the brand and the product model of the intelligent air conditioner.
Byte 2 records the control type, wherein the control type may include a set temperature, an up temperature, a down temperature, a set wind speed, a set wind swing, and the like. Each control type corresponds to a respective unique code value. The intelligent air conditioner can determine the control type carried in the control command by identifying the control type code value.
Byte 3 records control parameters 1, which may include specific temperature values, specific wind speeds, specific wind directions, and the like. And combining the control type recorded in the byte 2 to identify the effective information carried in the current control command. For example, if the control type is to raise the temperature, and the control parameter 1 is 3 degrees, the effective message is "raise the temperature by 3 degrees".
Byte 4 records control parameter 2, and under normal conditions, control parameter 2 is null, and is used to record a special command, for example, control parameter 2 corresponding to byte 4 is used only when the control command is a wake-up command, and control parameter 1 corresponding to byte 3 is used for other control commands, and by adopting this rule, the intelligent air conditioner can identify whether the current control command is a wake-up command.
Bytes 5 and 6 are reserved bytes which are also used for recording control parameters, and when bytes 3 and 4 are not enough for recording control parameters in the control command, bytes 5 and 6 are used for recording together. For example, the control parameters include an air volume, a current temperature value, an indoor temperature value, and an outdoor temperature value, and if only byte 3 and byte 4 are applied, it is obvious that only two control parameters, that is, the air volume and the current temperature value, can be recorded, and at this time, two reserved bytes, that is, byte 5 and byte 6, need to be combined to record the indoor temperature value and the outdoor temperature value.
Byte 7 records a check code that prevents physical transmission errors. In this embodiment, the check rule of the check code is: sum (i.e., byte 1+ byte 2+ byte 3+ byte 4+ byte 5+ byte 6) + 1. Of course, this is merely an exemplary check rule of the check code, and is not limited thereto, and the user may arbitrarily set the check rule of the check code according to needs.
TABLE 1
Byte(s) Encoding a value Means of
0 0xAA Synchronous head
1 0x08 Intelligent air conditioner ID
2 0xXX Type of control
3 0xXX Control parameter 1
4 0xXX Control parameter 2

In the embodiment, the intelligent air conditioner can recognize the control command sent by the voice equipment by presetting the N bytes in the control command, so that the aim of controlling the air conditioner by voice is fulfilled.
Table 2 is a table showing the encoded values of each byte of the control command in the speech control of the air conditioner according to an embodiment. As can be seen from table 2, different control types correspond to different encoding values, and different control parameters also correspond to different encoding values. Therefore, after the intelligent air conditioner decodes the control command, the effective information carried in the control command can be accurately determined according to the corresponding relation between the coding value and the control type, between the coding value and the control parameter and the like, and then the operation corresponding to the effective information is executed.

In one embodiment, as shown in fig. 3, when the code value includes an identification code value of the smart air conditioner, the step S13 may be performed as the following steps S31-S34:
step S31, acquiring the id from the valid information according to the first location information of the id code value in the preset command format.
Taking the above table 1 as an example, the first location information of the id code value is byte 1.
Step S32, judging whether the identity label is matched with the intelligent air conditioner; if the identity is matched with the intelligent air conditioner, executing step S33; if the identity does not match the smart air conditioner, step S34 is performed.
In step S33, an operation corresponding to the valid information is performed.
Step S34, the prompt information is fed back to the voice device. The prompt information is used for prompting that the identity carried in the control command is not matched with the intelligent air conditioner receiving the control command.
In the embodiment, whether corresponding operation is executed or not can be determined according to the identity in the effective information, so that the same voice device can simultaneously control a plurality of intelligent air conditioners, and any one of the intelligent air conditioners can be accurately and unmistakably controlled through verification of the identity.
In one embodiment, as shown in fig. 4, when the code values include control type code values and control parameter code values of the smart air conditioner, step S13 may be performed as the following steps S41-S42:
and step S41, acquiring the control type and the control parameter from the effective information according to the second position information corresponding to the control type code value and the third position information corresponding to the control parameter code value in the preset command format.
Taking the above table 1 as an example, the second location information corresponding to the control type code value is byte 2, and the third location information corresponding to the control parameter code value is byte 3 and byte 4.
And step S42, executing corresponding operation according to the control type and the control parameters.
In the embodiment, the control type and the control parameter can be acquired according to the position information of the control type code value and the control parameter code value in the preset command format, and then corresponding operation is executed according to the control type and the control parameter, so that the intelligent air conditioner can accurately identify the control type and the control parameter in the effective information, and the aim of controlling the air conditioner by voice is fulfilled.
In one embodiment, as shown in fig. 5, when the code values include control type code values and control parameter code values of the smart air conditioner, step S12 may be performed as the following steps S51-S54:
and step S51, acquiring the check code from the control command according to the fourth position information corresponding to the check code in the preset command format.
Taking the above table 1 as an example, the fourth location information corresponding to the check code is byte 7.
Step S52, according to the check rule of the check code in the preset command format, verifying whether the check code is correct; if the check code is correct, go to step S53; if the check code is erroneous, step S54 is performed.
For example, the check rule of the check code in the preset command format is as follows: sum (i.e., byte 1+ byte 2+ byte 3+ byte 4+ byte 5+ byte 6) + 1. And after the intelligent air conditioner receives the control command, acquiring the coded value recorded at the byte 7 as a check code, summing the coded values of the bytes 1-6 (the byte 0 is a synchronous head) according to a check rule, adding 1, comparing the obtained result with the check code, determining that the check code is correct if the comparison is consistent, and determining that the check code is wrong if the comparison is inconsistent.
And step S53, decoding the control command according to the preset command format.

In one embodiment, as shown in FIG. 6, the method further includes the following steps S61-S62:
step S61, when the control command fails to be decoded according to the preset command format, determining a preset standby command format; in at least a part of bytes in the preset spare command format, each byte corresponds to n encoding values, and n is a positive integer greater than 1.
In step S62, the control command is decoded according to the preset standby command format.
In one embodiment, as shown in FIG. 7, step S62 may be performed as steps S71-S73:
in step S71, fifth position information of at least a part of bytes in the preset spare command format is determined.
And step S72, splitting the byte corresponding to the fifth position information according to the splitting rule in the preset standby command format, and obtaining a split code value.
The splitting rule is to split the coded value corresponding to each byte at the fifth position information into n coded values respectively.
Step S73, decoding the split encoded value.
For example, assume that in the default spare command format, n is 2, and byte 3 and byte 4 each correspond to 2 encoded values. The splitting rule in the preset standby command format is to split the coded values corresponding to the bytes 3 and 4 into 2 coded values respectively. Then, the fifth position information of at least a part of bytes in the preset standby command format is byte 3 and byte 4, and after the intelligent air conditioner obtains the control instruction, the coded values corresponding to byte 3 and byte 4 are respectively split into 2 coded values according to the splitting rule, so as to obtain the split coded values.
In the embodiment, the control command can be decoded by adopting the preset standby command format under the condition that the decoding of the control command fails according to the preset command format, so that when the data in the effective information carried by the control command is more, the intelligent air conditioner can still accurately recognize the data in the effective information, and the accuracy of the user in using the voice control air conditioner is improved.
