Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device that enables various operations of an air conditioner, for example, to be controlled by an arbitrary operator's voice.

Generally, in order to operate an air conditioner, for example, an air conditioner, an operator must operate various operation switches provided on the indoor unit itself or a remote controller each time. For this reason, the air conditioner must be installed in a location that is easy to operate. That is, there is a problem in that there are restrictions on the installation location of the air conditioner. Also,
In order to operate an air conditioner, the operator must place his/her hands directly on the control unit, which is not only very troublesome, but also extremely difficult to control while doing other tasks. It is difficult to

The present invention has been made in view of the above circumstances, and its purpose is to provide a control device that can arbitrarily control various operations of, for example, an air conditioner using the voices of a specific number of operators. First, an overview of the present invention will be described. According to the present invention, various operational controls of an air conditioner are performed using the voice of an arbitrary operator, that is, spoken words (word commands). In this control method, the operator who wishes to operate the air conditioner first registers (memory) various required operating command words in the memory of the control device using his or her own voice (spoken words). After that, the operator inputs (speaks) the various command words registered above using his own voice as necessary, and compares the input command words with the various command words registered above. The system performs a comparison and executes various operation control operations set in advance based on the results of the comparison and verification. In this case, the number of operators is not limited and is determined by the capacity of the memory in which various command words are registered. The operator can also be changed by the operator's voice command. In addition to voice operation using voice control, it is of course possible to perform manual operation by the operator's manual operation, that is, normal operation using normal key operations. It can be switched either by operation) or by voice.

Each of the registration memories 36 ₁ to 36 ₄ can store the operator's name and 13 instruction words for each operator. Therefore, each registered memory 36 ₁ to 36 ₄ is connected to the OR circuit 5

Each output of ₁ to 51 ₄ is supplied to a display driver 53, and this driver 53 causes the audio registration section 1
2 (see FIG. 2), each of the display devices L ₁₂₁ to _{L 124} is selectively driven. That is, the operator to be registered or changed is displayed by the light emitting operation of each of the indicators _L121 to _L124 .

and a voice driving signal that commands the transition to voice driving.
_C12 is supplied to each set input terminal of a normal flip-flop circuit (hereinafter simply referred to as an FF circuit) 63 and an audio FF circuit 64 via NOR circuits 61 and 62, respectively. In addition, the above NOR circuits 61 and 62
The key signals from the key switches 15 and 18 (see FIG. 2) are sent to NAND circuits 65 and 65, respectively.
66. Therefore, the set output of the normal FF circuit 63 is used as the normal operation command signal _M0 , and the set output of the audio FF circuit 64 is outputted as the voice operation command signal _V0 , respectively, to the operation control unit 3.
(See Figure 1). Further, the reset output of the normal FF circuit 63 is connected to the reset input terminal of the audio FF circuit 64, and is also connected to the display _L15 (see FIG. 2) via the inverter circuit 67. The reset output of the FF circuit 63 is normally connected to the reset input terminal of the FF circuit 63, and is also connected to the display unit via the inverter circuit 68.
Connected to L ₁₈ (see Figure 2).

On the other hand, one end of the changeover switch 13 (see FIG. 2) is grounded, and the other end is connected to the power supply via a resistor 69.
Connected to Vc. In addition, this changeover switch 13
When set to the registration side (off), the system enters the voice registration and normal operation state, and when set to the command side (on), the system enters the voice operation state. Thus, the potential at the connection point 70 between the changeover switch 13 and the resistor 69 is supplied to the NAND circuits 65 and 66 via the inverter circuit 71. Further, the potential at the connection point 70 is supplied to an AND circuit 72 and also to an AND circuit 74 via an inverter circuit 73. Although not shown in detail, the AND circuits 72 actually have a number (17 pieces) corresponding to the key switches 12 ₁ to 12 ₄ and 14 ₁ to 14 ₁₃ in the voice operation operation section 1 ₁ of the control panel 1. There is also the above AND circuit 7
The number of key switches 4 corresponds to the number of key switches 12 ₁ to 12 ₄ (four pieces). The AND circuit 72 is supplied with each key signal K from the key input circuit 47 (see FIG. 3) in a corresponding manner, and the AND circuit 74 is supplied with the key switch 12 ₁ of the key signals K. Each key signal corresponding to 12 ₄ is supplied correspondingly.
Therefore, the output of the AND circuit 72 is the registration signal α
The output of the AND circuit 74 is sent to the selection circuit 41 (see FIG. 3) as a human change signal π (actually, there are 17 for the reason mentioned above). do)
to the memory selection section 45 (see FIG. 4) as
Each is supplied. Further, the potential at the connection point 70 is supplied to the operation control section 3 as a mode signal Ms indicating voice registration and whether the mode is normal operation mode or voice operation mode.

Next, the operation in the above configuration will be explained. First, when performing voice control, the operator registers his or her own spoken command words in the memory of the voice control unit 2 in advance. After that, the preset control operation is performed by the operator giving a command using the registered word. First, when an operator registers an instruction word, he or she sets the changeover switch 13 on the control panel 1 (see FIG. 2) to the registration side. Then, in FIG. 5, the changeover switch 13 is turned off, and a state in which voice registration is possible (voice registration mode) is entered. That is, when the changeover switch 13 is turned off, the connection point 70
The potential becomes high level and is supplied to the AND circuit 72. Further, when the potential of the connection point 70, that is, the mode signal Ms becomes high level, the operation control section 3 (see FIG. 1) determines that the voice registration mode is set, and sends each signal from the voice control section 2. inhibit the acceptance of In this state, the operator operates a predetermined key switch in the voice registration section 12 of the control panel 1 to designate his or her own registration address. When the key switch of the voice registration 12 is operated, a corresponding key signal K is outputted from the key input circuit 47 (see FIG. 3) and supplied to the AND circuit 72. At this time, the gate of the AND circuit 72 is opened by receiving a high-level signal as described above, so the key signal K from the key input circuit 47 is outputted from the AND circuit 72 as the registration signal α. The signal is supplied to a selection circuit 41 (see FIG. 3). This selection circuit 41 is
Voice registration memory 39 ₁ to 3 according to the registration signal α
9 ₄ and one of the voice command memories 40 ₁ to 40 ₁₃ is specified. For example, if the operator operates the key switch [1] 12 ₁ in the voice registration section 12, the selection circuit 41 specifies the voice registration memory 39 ₁ via the OR circuit 37 ₁ based on the registration signal α at that time. do.

Next, the operator inputs his or her name by voice through the microphone 11 of the control panel 1 (see FIG. 2). The voice information inputted from the microphone 11 is extracted by a specific frequency band by a voice extracting section 31 (see FIG. 3), and is supplied to a voice processing section 32. The audio processing unit 32 compresses the extracted audio information and temporarily stores it in the buffer memory 34. The voice information temporarily stored in the buffer memory 34 is written into the voice registration memory 39 ₁ already designated by the selection circuit 41 . Next, the operator selects the instruction word section 14 of the control panel 1.
(see Figure 2), by operating a predetermined key switch, a specific command word is specified,
Thereafter, the corresponding instruction word is input by voice through the microphone 11. By this operation, the instruction word is written into the designated voice instruction memory 40 ₁ to 40 ₁₃ . Hereinafter, in the same manner, instruction word part 1
By operating the key switch 4 and inputting the corresponding instruction word by voice, the above-mentioned 13 instruction words are registered in the voice instruction memories 40 ₁ to 40 ₁₃ .

Similarly, for other operators, the operator's name and 13 instruction words are stored in the voice registration memories 39 ₁ to 39 ₄ and the voice command memories 40 ₁ to 4.
You can register on ₀₁₃ . In this way,
It is possible to pre-register the names and 13 instruction words for each of the four operators in memory. Furthermore, when voice registration is performed in the voice registration memories 39 ₁ to 39 ₄ and the voice command memories 40 ₁ to 40 ₁₃ , the same voice information is also registered in the voice registration main memory 36 (see FIG. 4). It's summery. That is, the operator's name and 13 instruction words are registered for each operator in each of the registration memories 36 ₁ to 36 ₄ of the voice registration main memory 36 and saved as master information. As a result, the voice registration memories 39 ₁ to 39 ₄ and the voice command memory 4
If the contents of 0 ₁ to 40 ₁₃ are destroyed for some reason or an error occurs, the data is transferred from the voice registration main memory 36 to each of the above memories 39.
₁ to 39 ₄ and 40 ₁ to 40 ₁₃ can be written again.

When the operator's voice registration is completed in this way, the changeover switch 13 of the control panel 1 is switched to the command side. Then, in FIG. 5, the changeover switch 13 is turned on, and the voice operation becomes possible (voice operation mode). That is, when the changeover switch 13 is turned on, the potential at the connection point 70 becomes a low level (ground potential), closes the gate of the AND circuit 72, is converted to a high level by the inverter circuit 71, and is supplied to the NAND circuits 65 and 66. . These NAND circuits 65 and 66 normally operate the key switch 15 for normal operation and the key switch 18 for voice operation.
Since a high level signal is supplied from the circuit (see FIG. 2), each output signal thereof is at a low level. Further, when the potential of the connection point 70, that is, the mode signal Ms becomes low level, the driving control unit 3 determines that the voice driving mode is set,
The inhibit state of each signal from the audio control section 2 described above is released. However, in this state, when the normal operation state C ₁₁ or the voice operation signal C ₁₂ is output from the decoder 44 (see Fig. 3), the signal
Normal FF circuit 63 or audio FF by C ₁₁ and C ₁₂
The circuit 64 is set and a transition is made to normal operation or voice operation. For example, if an instruction word for voice driving is input now, a voice driving signal _C12 is output from the decoder 44, and the voice FF circuit 64 is set by the signal _C12 via the NOR circuit 62. Then, the set output of the audio FF circuit 64 becomes the audio driving command signal V ₀ to the driving control section 3.
(See FIG. 1), the voice operation becomes possible. Further, when the audio FF circuit 64 is set, its reset output is inverted so that the inverter circuit 68 drives the display _L18 to display the audio operation on the control panel 1.

In this state where voice operation is possible, the operator who has performed voice registration as described above arbitrarily gives voice commands, and control operations corresponding to the commands are performed. That is, when giving a control command by voice, the operator first inputs his or her own name by voice through the microphone 11. This input audio information is sent to the audio extractor 3 as described above.
1 and the audio processing unit 32 to the buffer memory 34, and then the comparator 43
(See Figure 3). At this time, comparator 4
3 is supplied with information (operator's name) registered in advance in the voice registration memories 39 ₁ to 39 ₄ via a multiplexer 42 . Thereby, the comparator 43 performs speech recognition by comparing and collating the input speech information with memory information registered in advance, and outputs a matching signal to the decoder 44 when both pieces of information match. Decoder 4
4 decodes the memory information from the voice registration memories 39 ₁ to 39 ₄ supplied via the multiplexer 42 at this time, and outputs any one of the operator signals O ₁ to _{O 4} . Each address of the voice command memories 40 ₁ to 40 ₁₃ is designated by this outputted operator signal, and the registration instruction words corresponding to the operator at this time are sequentially read out by the multiplexer 42 and sent to the comparator 43 and the decoder. 44
supplied to

On the other hand, after inputting the name, the operator then similarly inputs a predetermined command word by voice. The input instruction word is temporarily stored in the buffer memory 34 as described above, and then supplied to the comparator 43 where it is compared with the registered instruction word read out from the voice instruction memories 40 ₁ to 40 ₁₃ . Then, when a match occurs, the match signal is supplied to the decoder 44, so that the voice command memories 40 ₁ to 40 ₁₃ that are being supplied via the multiplexer 42 at this time are
The registration instruction word from is decoded by the decoder 44, and one of the decode signals C ₁ to C ₁₃ is outputted to perform a control operation for the instruction word. For example, when a cooling instruction word is input, the decoder 44 outputs the cooling signal _C6 , which is supplied to the operation control unit 3, so that the operation control unit 3 can control the cooling and heating in the refrigeration cycle of the air conditioner 5, for example. Switch the four-way switching valve (not shown) to the cooling cycle side to set the cooling operation mode. When a designation word designating, for example, room A as the room to be cooled is input, a room A signal C ₁ is output from the decoder 44 and is supplied to the operation control unit 3. opens the solenoid valve (not shown) for connecting the indoor unit installed in Room A with the refrigeration cycle, and also makes the blower (not shown) of the indoor unit ready for operation. In this state, when the start instruction word is input, the decoder 4
4 outputs a start signal _C4 , which is supplied to the operation control section 3.
drives the compressor (not shown) in the refrigeration cycle and also drives the blower of the indoor unit in room A, and the cooling operation of room A is started. After that, the operation control unit 3 detects the room temperature detector 4 in room A.
This system performs well-known room temperature control based on signals from. In this case, the indicator L _27a of the driver's room display section 27 (see Figure 2) lights up, and the control panel 1
Room A operation is displayed at the top. Similarly, by inputting an instruction word for room B, room C, etc., cooling operation for room B or room C or all of the rooms is performed. The above description has been about the cooling operation, but when performing the heating operation, by inputting the heating instruction word, the heating operation control for each room can be performed through the same operation as the cooling operation described above.

Therefore, when switching from voice operation as described above to normal operation (manual operation) by key operation, it can be done by either voice command or key operation. That is, when switching to normal operation by voice, for example, by inputting a normal operation instruction word by voice from the microphone 11, the normal operation signal _C11 is output from the decoder 44, and the signal _C11 is outputted from the decoder 44. The normal FF circuit 63 is set via the NOR circuit 61.
Then, the set output of the normal FF circuit 63 becomes the normal operation command signal _M0 and is supplied to the operation control section 3, thereby enabling normal operation. Further, when the normal FF circuit 63 is set, its reset output is inverted so that the inverter circuit 67 drives the display _L15 to display the normal operation on the control panel 1. On the other hand, when switching to normal operation by key operation, the key switch 15 for normal operation (see FIG. 2) is operated. By operating the key switch 15, the input signal from the key switch 15 to the NAND circuit 65 (see FIG. 5) becomes low level, and the output of the NAND circuit 65 becomes high level. Therefore,
The output of NOR circuit 61 becomes low level and normal
The FF circuit 63 is set and becomes ready for normal operation as described above. In this normal operation ready state, the normal operation operation section 1 ₂ (second
(see figure 1), by giving desired driving commands etc. by key operations similar to conventional ones, those command signals etc. are transmitted to the driving control section 3 (see figure 1).
The operation control unit 3 performs operation control by well-known manual operation. Note that, contrary to the above case, when switching from normal operation to voice operation, it can be performed either by voice command or key operation in the same manner as in the above case.

In addition, when changing the registered person (operator) in the voice operation state, the pre-registered operator first inputs the instruction word for changing the person from the microphone 11, and then enters the name. input. When the instruction word for changing the person is input, the decoder 44 outputs a voice change signal C ₁₃ for the person, which is sent to the AND circuits 52 ₁ to 52
₄ (see Figure 4). Next, one of the operator signals O ₁ to _{O 4} is outputted from the decoder 44 and supplied to the corresponding one of the AND circuits 52 ₁ to 52 ₄ . Therefore, the output of one of the AND circuits 52 ₁ to 52 ₄ becomes high level, and one of the registration memories 36 ₁ to 36 ₄ (see FIG. 4) is designated via the OR circuits 51 ₁ to 51 ₄ . . In this state, the newly registering operator inputs his name and 13 instruction words by voice from the microphone 11, thereby registering the registered memory 36 ₁ to 3 designated as described above.
6 Registered as one of ₄ (rewritten). Then, by rewriting the contents of the voice registration memories _{391 to 394} and the voice command memories ₄₀₁ to ₄₀₁₃ (see Fig. 3) using the memory information of the registration memories 361 to ₃₆₄ , Complete the registration change. On the other hand, when changing the person by key operation, the key switches 12 ₁ to 12 ₄ of the voice registration section 12 are used.
(See Figure 2) to specify the registration address you wish to change. When the key switches 12 ₁ to 12 ₄ are operated, a key signal K is output from the key input circuit 47 (see FIG. 3), which is sent to the AND circuit 74 (the fifth
(see figure). As a result, the AND circuit 74 outputs the key-based change signal π,
By supplying it to the registration memories 36 ₁ to 36 ₄ (see FIG. 4) via the OR circuits 51 ₁ to 51 ₄ , one of the registration memories 36 ₁ to 36 ₄ is designated. After this, the newly registered operator inputs the name and 13 instruction words by voice, and the name is registered in one of the designated registration memories 36 ₁ to 36 ₄ as described above.

As described above, set the changeover switch 13 to the voice operation side,
In other words, when it is turned on, it can be switched to any operating state by voice or key operation. On the other hand, without any voice control,
When controlling the operation only by normal key operations, the changeover switch 13 is switched to the normal operation (voice registration) side, that is, to the off state. Then, the potential at the connection point 70 (see FIG. 5), that is, the mode signal Ms becomes high level, and the operation control unit 3 determines that the normal operation mode is set, and each signal from the audio control unit 2 inhibit the acceptance of However, in this state, when the operator gives a driving command in the normal driving operation part ₁₂ of the control panel 1 by the same key operation as in the past, the driving control part 3 causes the driving to be started by the well-known manual operation. It is something that is controlled.

As described in detail above, the present invention is such that the operator registers various driving command words in advance using his/her own voice, and the operator inputs the various registered command words using his/her own voice. The input command word is compared and verified with the various registered command words, and various preset driving control operations are performed based on the results.

Therefore, according to the present invention, it is possible to perform various driving controls using the voices of a specific number of operators, and there is almost no need for the operators to take direct action. This makes it easy to control the operation of air conditioners, etc., which is very convenient.

In addition, the registration of driving command words is based on the operator's own voice.In other words, the registered content is not only the driving command word but also a voice pattern unique to the registrant. The determination as to whether the word is a registered driving instruction word and the determination as to whether the voice is the voice pattern of the registrant are completed at the same time, and high reliability can be ensured regarding comparison and verification.

Furthermore, in the present invention, it is possible to register and display multiple operators, so in devices operated by multiple people, such as household electrical appliances, specific multiple operators, such as all family members, can be registered and displayed. It is highly practical.

In the second invention, in addition to the above-mentioned effects, it is possible to switch between voice operation by voice control and normal manual operation by manual operation by the operator, and the switching can be performed by either voice or manual operation. Even an operator whose voice is not registered can switch to manual operation and control the operation, which is even more convenient.
