[0024] Currently, in existing HVAC systems, the high-voltage power supply is directly connected to the low-voltage HVAC equipment, lacking effective electrical isolation.

[0025] To address the issue of low safety in HVAC equipment, this utility model provides an intelligent HVAC system. The intelligent HVAC system includes: a heating module; a control module, including a first processor and a first communicator, the first processor and the first communicator being electrically connected; a safety switch module, including an optocoupler, a thyristor, and a temperature control switch, the first processor being connected to the input terminal of the optocoupler, the output terminal of the optocoupler being connected to the control electrode of the thyristor, the anode of the thyristor being connected to a power supply, the cathode of the thyristor being connected to the input terminal of the temperature control switch, the output terminal of the temperature control switch being connected to the heating module, and the sensing terminal of the temperature control switch being in contact with the heating module; and a host computer, including a second processor, a second communicator, and an operating component, the second communicator and the operating component being electrically connected to the second processor, and the second communicator being communicatively connected to the first communicator. The solution provided by this utility model embodiment can improve the overall stability and safety of the equipment.

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 This utility model provides an intelligent heating, ventilation, and air conditioning system, including:

[0028] Heating module 100;

[0029] The control module 200 includes a first processor 210 and a first communicator 220, wherein the first processor 210 is electrically connected to the first communicator 220;

[0030] The safety switch module 300 includes an optocoupler 310, a thyristor 320, and a temperature control switch 330. The first processor 210 is connected to the input terminal of the optocoupler 310, the output terminal of the optocoupler 310 is connected to the control electrode of the thyristor 320, the anode of the thyristor 320 is connected to the power supply, the cathode of the thyristor 320 is connected to the input terminal of the temperature control switch 330, the output terminal of the temperature control switch 330 is connected to the heating module 100, and the sensing terminal of the temperature control switch 330 is in contact with the heating module 100.

[0031] The host computer 400 includes a second processor 410, a second communicator 420, and an operation component. The second communicator 420 and the operation component are electrically connected to the second processor 410, and the second communicator 420 is communicatively connected to the first communicator 220.

[0032] Understandably, the heating module 100 is used to heat the indoor environment. Between the heating module 100 and the control module 200, a safety switch module 300 is installed. The safety switch module 300 includes an optocoupler 310, a thyristor 320, and a temperature control switch 330. The input terminal of the optocoupler 310 is connected to the first processor 210, and the optocoupler 310 directly receives control information from the first processor 210. Therefore, the first processor 210 can directly drive the connection state of the output terminal of the optocoupler 310. The output terminal of the optocoupler 310 is connected to the control terminal of the thyristor 320, so the connection state of the output terminal of the optocoupler 310 can also be controlled. The connection state of the thyristor 320 is directly affected. The thyristor 320 is used to connect the power supply and the temperature control switch 330. The sensing end of the temperature control switch 330 is in contact with the heating module 100. Therefore, the temperature control switch 330 can control its own connection state according to the actual temperature of the heating module 100. In summary, the thyristor 320 and the temperature control switch 330 are provided between the power supply and the heating module 100. The first processor 210 controls the connection or disconnection of the thyristor 320 through the optocoupler 310. Therefore, the safety switch module 300 can separate the first processor 210, the power supply and the heating module 100 to ensure the stability of each component of the HVAC system.

[0033] Optionally, the second processor 410 sends a control command to the first communicator 220 via the second communicator 420. After the first processor 210 receives the command to start heating, the first processor 210 controls the input terminal of the optocoupler 310 to be energized, thereby turning on the output terminal of the optocoupler 310. After the control terminal of the thyristor 320 receives a high-level signal from the output terminal of the optocoupler 310, the thyristor 320 is turned on. Under the premise that the surface temperature of the heating module 100 is normal, the temperature control switch 330 is in the on state. At this time, the heating module 100 can be normally connected to the power supply, thereby starting the heating operation.

[0034] When the first processor 210 receives the command to stop heating, it controls the input of the optocoupler 310 to be de-energized, causing the output of the optocoupler 310 to disconnect. At this time, the control terminal of the thyristor 320 turns to a low level, the thyristor 320 disconnects, and the heating module 100 stops supplying heat. Similarly, when the surface temperature of the heating module 100 is abnormal, the temperature control switch 330 disconnects itself, which can also control the heating module 100 to stop supplying heat.

[0035] In addition, such as Figure 3 As shown, in some embodiments of the present invention, the safety switch module 300 further includes a circuit breaker 340, one end of which is connected to a power supply, and the other end of which is connected to the anode of the thyristor 320. The circuit breaker 340 is also connected to the first processor 210.

[0036] Circuit breaker 340 is used to implement overload and short circuit protection between the power supply and the heating module 100. The power supply side of circuit breaker 340 can be connected to mains power, energy storage battery or photovoltaic module based on environmental protection principles. When the circuit condition between the power supply and the heating module 100 is abnormal, circuit breaker 340 will automatically disconnect the circuit to improve the stability of heating module 100.

[0037] Optionally, the safety switch module 300 also includes a transformer 350 and a rectifier bridge 360, with the circuit breaker 340, transformer 350 and rectifier bridge 360 ​​connected in sequence, and the rectifier bridge 360 ​​also electrically connected to the first processor 210.

[0038] Transformer 350 converts high-voltage power to low-voltage power suitable for the first processor 210. The rectifier converts AC power to DC power. By first inputting the high-voltage AC power to transformer 350 for step-down, and then inputting it to the rectifier for conversion to DC power, the hardware requirements of the rectifier can be reduced, thereby reducing the cost of the HVAC system.

[0039] The circuit breaker 340 is equipped with a control port. The first processor 210 is connected to the control port of the circuit breaker 340. The first processor 210 can actively control the on / off state of the circuit breaker 340. The first processor 210 detects the overall working status of the HVAC system. When it detects that some components of the HVAC system are leaking electricity, the first processor 210 controls the circuit breaker 340 to disconnect the circuit, thereby disconnecting the power supply from the HVAC system and ensuring the safety of the user.

[0040] The HVAC system also includes an energy storage module 230, which is electrically connected to the control module 200.

[0041] The energy storage module 230 is used to power the first processor 210 and the first communicator 220. When the HVAC system loses external power supply, the energy storage module 230 can also provide power to the control module 200 temporarily. The first processor 210 organizes the overall information of the current HVAC system and sends it to the host computer 400 through the first communicator 220.

[0042] Optionally, the control module 200 may also include indicator lights, which are electrically connected to the first processor 210. The indicator lights are used to display the operating status of the HVAC system.

[0043] In addition, such as Figure 4 As shown, in some embodiments of this utility model, the host computer 400 includes a temperature sensor 430 and a humidity sensor 440. The temperature sensor 430 and the humidity sensor 440 are electrically connected to the second processor 410, respectively. The temperature sensor 430 is used to acquire temperature information, and the humidity sensor 440 is used to acquire humidity information.

[0044] The host computer 400 integrates a pre-set control strategy. After the temperature sensor 430 and humidity sensor 440 collect temperature information and humidity information respectively, the second processor 410 determines the real-time control command according to the control strategy and sends it to the first communicator 220 through the second communicator 420, which is then executed by the first processor 210.

[0045] In addition, the host computer 400 also includes a voice control module 450200, which is electrically connected to the second processor 410 and is used to receive voice control commands.

[0046] The voice control module 450200 includes a microphone and a speaker. The host computer 400 has a pre-trained voice recognition model built in. Users can give commands to the HVAC system. With the user's authorization, the host computer 400 acquires the user's voice through the microphone, recognizes the user's semantics through the voice recognition model, and matches the corresponding control strategy. Alternatively, when the control strategy of the HVAC system changes, the second processor 410 matches the words and pronunciations corresponding to the control strategy from a preset pronunciation table. After organizing the words into a sentence, the corresponding pronunciation is played through the speaker.

[0047] In addition, the host computer 400 also includes a third communicator 460, which is electrically connected to the second processor 410 and is used to communicate with external smart devices.

[0048] Users can connect to the third communicator 460 through their own smart devices to obtain various information about the HVAC system. The smart devices include, but are not limited to, smartphones, computers, operable displays, or remote servers. Users can also send control commands to the third communicator 460 through their smart devices to control the operation mode of the HVAC system.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
