Description

Technical Field

[0001] This utility model relates to the field of smart speaker technology, specifically to a smart speaker control system. Background Technology

[0002] Existing network-connected smart speakers use proprietary protocols that are not open to third parties and only serve their corresponding products.

[0003] In summary, there is a need to provide a smart speaker control system to solve the problem in existing technologies where smart speakers cannot directly control PLC controllers and connected terminal devices. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] Example:

[0024] See Figure 1A smart speaker control system includes a smart speaker 1, a switch module assembly 2, a power supply 3, a PLC controller 4, and a terminal device (a booster fan may be selected, but is not shown in the figure).

[0025] The smart speaker 1 is connected to a wireless network and is also wirelessly connected to the switch module assembly 2, specifically via Bluetooth or a wireless network.

[0026] The switch module assembly 2 includes a first switch module K1; the common terminal of the relay in the first switch module K1 is connected to the positive terminal of the power supply 3, the positive terminal of the input terminal of the first switch module K1 is connected to the positive terminal of the power supply 3, and the negative terminal of the input terminal of the first switch module K1 is connected to the negative terminal of the power supply 3.

[0027] The normally open terminal (normally open terminal, i.e., normally open contact) of the relay in the first switch module K1 is connected to the digital input terminal of the PLC controller 4;

[0028] The positive terminal of the PLC controller 4 is connected to the positive terminal of the power supply 3, and the negative terminal of the PLC controller 4 is connected to the negative terminal of the power supply 3.

[0029] The terminal device is connected to the PLC controller 4.

[0030] The switch module assembly 2 further includes a second switch module K2; the common terminal of the relay in the second switch module K2 is connected to the positive terminal of the power supply 3, the positive terminal of the input terminal of the second switch module K2 is connected to the positive terminal of the power supply 3, and the negative terminal of the input terminal of the second switch module K2 is connected to the negative terminal of the power supply 3.

[0031] The normally open terminal of the relay in the second switch module K2 is connected to the digital input terminal of the PLC controller 4.

[0032] The power supply 3 is a DC power supply (specifically, 12V or 24V can be selected).

[0033] The smart speaker control system described in this embodiment solves the problem in the prior art where the smart speaker 1 cannot directly control the PLC controller 4 to control the terminal equipment. Specifically, power supply 3 supplies power to both the switch module component 2 and the PLC controller 4, and the normally open terminal of the relay in the switch module component 2 is connected to the digital input terminal of the PLC controller 4. The networked smart speaker 1 is connected to the switch module component 2. Voice commands are issued to the smart speaker 1 through human-machine interaction, and the smart speaker 1 sends switch signals to the switch module component 2. The switch signals directly control the operation of the PLC controller 4 to control the terminal equipment. The control logic built into the PLC controller 4 is existing technology.

[0034] Specifically, the specific operation method of the networked smart speaker 1 control terminal device (i.e., booster fan) in this embodiment is shown in Table 1 below.

[0035] Table 1. Specific Operating Methods of Smart Speaker 1 Linked with Booster Fan

[0036]

[0037]

[0038] As shown in Table 1, when the operator says "Please turn off the system" to the smart speaker 1, the smart speaker 1 recognizes the instruction as turning off the system and executes the application scenario control. The first switch module K1 turns off and the second switch module K2 turns off. The PLC controller 4 obtains the normally open contact signal of the first switch module K1 and the normally open contact signal of the second switch module K2. The PLC controller 4 executes the system shutdown program to realize the shutdown of the booster fan.

[0039] When the operator says "Please turn on the system" to the smart speaker 1, the smart speaker 1 recognizes the command as turning on the system and executes the application scenario control. The first switch module K1 is turned off and the second switch module K2 is turned on. The PLC controller 4 obtains the normally open contact signal of the first switch module K1 and the normally open contact signal of the second switch module K2. The PLC controller 4 executes the system turn-on program to turn on the booster fan.

[0040] When the operator says "Please increase system pressure" to the smart speaker 1, the smart speaker 1 recognizes the instruction as increasing the system pressure by 5 kPa, executes the application scenario control, turns on the first switch module K1 and turns off the second switch module K2, the PLC controller 4 obtains the normally open contact signal of the first switch module K1 and the normally open contact signal of the second switch module K2, and the PLC controller 4 executes the program to increase the system pressure by 5 kPa, so that the booster fan can perform the operation of increasing the pressure by 5 kPa.

[0041] When the operator says "Please reduce system pressure" to the smart speaker 1, the smart speaker 1 recognizes the instruction as reducing the system pressure by 5 kPa, executes the application scenario control, turns on the first switch module K1 and the second switch module K2, and the PLC controller 4 obtains the normally open contact signals of the first switch module K1 and the second switch module K2. The PLC controller 4 executes the program to reduce the system pressure by 5 kPa, thereby enabling the booster fan to perform the operation of reducing the pressure by 5 kPa.

[0042] To facilitate fuzzy control, operators can train multiple voice commands to recognize a single instruction. For example, training the voice commands "Please shut down the system", "Shut down the system", "Please shut down the system", and "Shut down the system" can all execute the system shutdown command, thus improving the flexibility of control.

[0043] To increase the number of definable identification commands, the number of switch modules can also be increased in switch module component 2. If switch module component 2 only includes the first switch module K1, then the number of definable identification commands is only two, namely "system on" and "system off". If switch module component 2 includes the first switch module K1 and the second switch module K2, then the number of definable identification commands is four, as shown in Table 1.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
