[0033] In some embodiments, such as Figure 1 As shown, this disclosure provides a control device for an air conditioning component, including a main control chip 01, a drive device 02, and a voltage conversion device 03, etc. The main control chip 01 can be the main control chip for an air conditioner, etc. Air conditioners can be of various types, such as wall-mounted air conditioners, central air conditioners, etc. The main control chip 01 can be of various types, such as an MCU (Microcontroller Unit), etc.
[0034] The drive device 02 can be implemented in various ways. The drive device 02 is connected to the main control chip 01 and the voltage conversion device 03 respectively. The drive device 02 receives the control data sent by the main control chip 01, converts the control data into level control signals of the air conditioning element, and sends the level control signals to the voltage conversion device. The control data can be of various types.
[0035] The voltage conversion device 03 can be implemented in various ways. The voltage conversion device 03 is connected to the drive device 02 and the air conditioning element 04 respectively. The voltage conversion device 03 performs voltage conversion processing on the level control signal sent by the drive device 02 and sends the voltage-converted level control signal to the air conditioning element 04.
[0036] The control device for air conditioning components disclosed herein converts control data sent by the main control chip into level control signals for the air conditioning components through a drive device, performs voltage conversion processing on the level control signals through a voltage conversion device, and sends them to the air conditioning components. This reduces the port occupation of the main control chip by the air conditioning components, lowers costs, and effectively improves the utilization efficiency of the main control chip. It can perform voltage conversion on the level control signals, adapt to the voltage requirements of different air conditioning components, and can control a variety of air conditioning components, thus improving the compatibility of the control device.
[0037] The air conditioning element 04 can be of various types, such as an electronic throttling element for the air conditioner, or other level-driven solenoid valves; the electronic throttling element can be an electronic expansion valve, etc.; the number of air conditioning elements 04 can be one or more, and the level control signal corresponding to one air conditioning element may be multiple. For example, the control of the electronic expansion valve requires four control signals, that is, the number of level control signals corresponding to the electronic expansion valve is four.
[0038] Using the control device disclosed herein to control air conditioning components with multiple level control signals can reduce the port occupation of the main control chip by the air conditioning components, reduce costs and effectively improve the utilization efficiency of the main control chip. Furthermore, it can realize expansion functions and adapt to the control expansion of multiple components in the unit.
[0039] In some embodiments, the main control chip 01 and the driving device 02 can be connected via a bus, such as an SPI (Serial Peripheral Interface) bus. Communication between the main control chip 01 and the driving device 02 via the SPI bus enables high-speed data transmission with strong real-time performance and high reliability.
[0040] The driving device 02 may include at least one driving chip, which may be of various types. The driving chip is connected to the main control chip 01 and the voltage conversion device 03 respectively, and is used to convert the control data sent by the main control chip 01 into level control signals and send them to the voltage conversion device.
[0041] By converting control data into level control signals for the air conditioning components using a driver chip, the occupancy of the main control chip by the air conditioning components can be reduced, effectively improving the utilization efficiency of the main control chip, reducing costs, and enhancing the scalability of the drive device.
[0042] The voltage conversion device 02 may include at least one voltage conversion chip, which may be of various types. The voltage conversion chip may be connected to at least one driving chip and at least one air conditioning element respectively, for performing voltage conversion processing on the level control signal sent by the driving chip, and sending the voltage-converted level control signal to the corresponding air conditioning element.
[0043] By using a voltage conversion chip to convert the level control signal into voltage, it is possible to adapt to the voltage requirements of different air conditioning components, control a variety of air conditioning components, improve the compatibility and stability of the control device, and enhance the scalability of the voltage conversion device.
[0044] A voltage conversion chip can convert a first voltage of a level control signal into a second voltage, where the second voltage is greater than the first voltage, or the second voltage is less than or equal to the first voltage. For example, a voltage conversion chip can convert a first voltage of 3.3V to a second voltage of 12V, or a voltage conversion chip can convert a first voltage of 3.3V to a second voltage of 1.5V, etc.
[0045] By using a voltage conversion chip to increase the voltage of the level control signal, it is possible to adapt to the high voltage of different air conditioning components and improve the compatibility of air conditioning component control.
[0046] In some embodiments, the number of driver chips can be one or more, and each driver chip can be independently connected to the main control chip; or, the number of driver chips can be multiple, and multiple driver chips form a cascaded structure; wherein, the data input port of the first-level driver chip is connected to the main control chip; the data shift port of the previous-level driver chip is connected to the data input port of the next-level driver chip; and the signal input port of each driver chip is connected to the main control chip.
[0047] By cascading multiple driver chips, it is not necessary to occupy new ports of the main control chip. The data input port of the first-level driver chip is connected to the main control chip, and the data shift port of the previous-level driver chip is connected to the data input port of the next-level driver chip. When it is necessary to add driver chips and air conditioning components, there is no need to increase the port occupation of the main control chip. Only the driver chips need to be cascaded, which effectively improves the utilization efficiency of the main control chip and enhances the scalability of the drive device.
[0048] The signal input ports of the driver chip include clock synchronization ports and latch ports. By connecting the clock synchronization ports and latch ports of the driver chip to the main control chip, the driver chip can be controlled to perform conversion processing simultaneously, ensuring synchronous control of multiple air conditioning components and improving the real-time performance and accuracy of the control.
[0049] In some embodiments, the air conditioning components in various air conditioners, such as variable frequency air conditioners, include electronic expansion valves. There are a large number of electronic expansion valves, and multiple electronic expansion valves usually need to be controlled synchronously. If each electronic expansion valve is directly connected to the main control chip, the number of ports occupied by the main control chip will be large, which will affect the efficiency of the main control chip.
[0050] like Figure 2 As shown, the control device for the air conditioning component includes: a main control chip 01, a drive unit, and a voltage conversion device, etc. The drive unit includes drive chip 021 and drive chip 022, etc. The voltage conversion device includes voltage conversion chip 031 and voltage conversion chip 032, etc.
[0051] Air conditioning components include air conditioning component 041, air conditioning component 042, air conditioning component 043, air conditioning component 044, etc. Air conditioning components 041-044 are all electronic expansion valves, and each electronic expansion valve corresponds to four level control signals.
[0052] Driver chip 021 and driver chip 022 form a cascaded structure. The data input port of the first-stage driver chip 021 is connected to the main control chip 01. The data shift port DATA of the previous-stage driver chip 021 is connected to the data input port of the next-stage driver chip 022. The signal input ports of driver chip 021 and driver chip 022 are connected to the main control chip 01. The signal input ports of driver chip 021 and driver chip 022 include clock synchronization ports and latch ports.
[0053] The main control chip 01 can connect to the driver chips 021 and 022 via a three-wire SPI communication method. It can be configured with a high-speed communication mode, where the main control chip 01 is the master device and is set to SPI master mode; the driver chips 021 and 022 are slave devices and are configured to slave mode. Driver chips 021 and 022 can be various chips, such as the HC595 chip.
[0054] In three-wire SPI communication, the SCK, STCP, and MOSI signal lines need to be configured. SCK (Serial Clock) is the clock signal line, generated by the master control chip 01, used to synchronize data transmission between the master control chip 01 and driver chips 021 and 022. STCP (Storage Clock Pulse, or RCLK) is the storage clock pulse line, used to latch data in the shift register to the output register, triggering parallel data output. MOSI (Master Out Slave In) is the master device output and slave device input line, with data flow from the master device to the slave device.
[0055] The chip's ports can consist of one or more pins. The data input port of the first-level driver chip 021 is connected to the main control chip 01 via the MOSI signal line; the data shift port DATA of the previous-level driver chip 021 is connected to the data input port of the next-level driver chip 022; the clock synchronization ports and latch ports of driver chips 021 and 022 can be connected to the main control chip 01 via the SCK signal line and the Stcp signal line.
[0056] The main control chip 01 sends two control data to control the air conditioning components 041-044. Each control data is an 8-bit SPI data (one byte in length). Each bit of the 8-bit SPI data represents a level, with 1 representing a high level and 0 representing a low level. The two control data are two bytes in length.
[0057] Voltage conversion chips 031 and 032 can be of various types and are used for voltage conversion. Voltage conversion chip 031 is connected to air conditioning element 041 and air conditioning element 042 respectively, and voltage conversion chip 031 is connected to driver chip 021; air conditioning element 041 and air conditioning element 042 each correspond to four level control signals.
[0058] The main control chip 01 and the driver chip 021 use a 3.3V power supply as their operating power, while the voltage conversion chip 031 uses a 12V power supply. The voltage conversion chip 031 converts the eight-level 3.3V control signals sent by the driver chip 021 into eight-level 12V control signals, and sends four-level 12V control signals to the air conditioning components 041 and 042 respectively.
[0059] Voltage conversion chip 032 is connected to air conditioning components 043 and 044 respectively, and is also connected to driver chip 022. Air conditioning components 043 and 044 correspond to the four level control signals sent by driver chip 022. Voltage conversion chip 032 converts the eight 3.3V level control signals sent by driver chip 022 into eight 12V level control signals, and sends the four 12V level control signals to air conditioning components 043 and 044 respectively.
[0060] For driver chip 021, port 10 is the clock synchronization port, port 11 is the latch port, port 12 is the data input port, and port 9 is the data shift port (DATA). The port settings for driver chip 022 are the same as for driver chip 021. The data shift port (DATA) for both driver chips 021 and 022 is a data signal synchronization shift port.
[0061] The main control chip 01 periodically sends control data to the first-level driver chip 021 according to the preset control interval time. The control interval time can be set, for example, 1ms. When the driver chip 021 receives the control data, the driver chip 021 sends the previously received control data to the data input port of the next-level driver chip through the data shift port DATA.
[0062] If there is a next-level driver chip in the cascaded structure, when driver chip 022 receives control data, driver chip 022 will send the previously received control data to the data input port of the next-level driver chip through the data shift port DATA.
[0063] For example, the preset control interval is 1ms, and the control data is DATA1 (corresponding to air conditioning components 043-044) and DATA2 (corresponding to air conditioning components 041-042); the length of DATA1 and DATA2 is 1 byte. The control data corresponding to air conditioning component 043 can be 0001, the control data corresponding to air conditioning component 044 can be 0010, the control data corresponding to air conditioning component 041 can be 0100, and the control data corresponding to air conditioning component 042 can be 1000. Then, the control data DATA1 and DATA2 are 8 bits (one byte), and each bit in DATA1 and DATA2 represents a level control signal.
[0064] The main control chip 01 periodically sends control data DATA1 and DATA2 to the primary driver chip 021 according to a preset control interval of 1ms. When the main control chip 01 sends control data DATA1, the driver chip 021 receives the control data DATA1. If the driver chip 021 did not receive the control data in the previous step, it will not send data.
[0065] The main control chip 01 sends control data DATA2 after a 1ms interval. When the driver chip 021 receives the control data DATA2, the driver chip 021 sends the previously received control data DATA1 to the data input port of the next-level driver chip 022 through the data shift port DATA, thus synchronizing the control data DATA1 to the driver chip 022.
[0066] The latch ports of driver chips 021 and 022 are used to prevent unstable changes in the output level of driver chips 021 and 022 when the main control chip 01 sends control data.
[0067] After the main control chip 01 sends control data DATA1 and control data DATA2, the main control chip 01 sends an enable signal to the latch ports of the driver chip 021 and driver chip 022 through the STCP signal line, controlling the driver chip 021 and driver chip 022 to perform synchronous conversion.
[0068] When driver chip 021 receives an enable signal, driver chip 021 converts the latest received control data DATA2 into eight-level control signals and sends the eight-level control signals to voltage conversion chip 031; driver chip 022 converts the latest received control data DATA1 into eight-level control signals and sends the eight-level control signals to voltage conversion chip 032.
[0069] Voltage conversion chip 031 converts the eight-level control signals sent by driver chip 021 into eight-level 12V control signals, and sends four-level 12V control signals to air conditioning components 041 and 042 respectively. Voltage conversion chip 032 converts the eight-level control signals sent by driver chip 022 into eight-level 12V control signals, and sends four-level 12V control signals to air conditioning components 043 and 044 respectively.
[0070] If an additional driver chip is needed based on the number of air conditioning components, connect the data input port of the new driver chip to the data shift port (DATA) of driver chip 022, and connect the clock synchronization port and latch port of the new driver chip to the main control chip 01. That is, the connection method between the new driver chip and the main control chip 01 and driver chip 022 is the same as the connection method between driver chip 022 and the main control chip 01 and driver chip 021, forming a new cascaded structure. A new voltage conversion chip can also be added. Connect the new driver chip to the new voltage conversion chip, and the new voltage conversion chip to the new air conditioning components, in the same way as the connection method between driver chip 022 and voltage conversion chip 032. The new driver chip converts the received control data into level control signals for the air conditioning components and sends them to the new voltage conversion chip. Based on the same method, further expansion of the driver chip, voltage conversion chip, and air conditioning components can be achieved.
[0071] In some embodiments, a corresponding voltage conversion chip can be provided for each air conditioning component. For example... Figure 3 As shown, the control device for the air conditioning components includes a main control chip 01, a drive unit, and a voltage conversion device. The drive unit includes drive chips 021 and 022. The voltage conversion device includes voltage conversion chips 033-036. The air conditioning components include air conditioning components 041, 042, 043, and 044.
[0072] Driver chips 021 and 022 form a cascaded structure. Voltage conversion chips 033-036 are connected one-to-one with air conditioning components 041-044 respectively, and voltage conversion chips 033-034 are connected to driver chip 021; voltage conversion chips 035-036 are connected to driver chip 022; air conditioning components 041-044 are all electronic expansion valves, and each electronic expansion valve corresponds to four level control signals.
[0073] The control device for the air conditioning components described in the above embodiments can reduce the port occupation of the main control chip by the air conditioning components, reduce costs, and effectively improve the utilization efficiency of the main control chip; it can perform voltage conversion on the level control signal, adapt to the voltage requirements of different air conditioning components, and control multiple air conditioning components, thereby improving the compatibility and scalability of the control device; it can control the driver chip to perform conversion processing simultaneously through cascading, ensuring synchronous control of multiple air conditioning components and improving the real-time performance and accuracy of the control.
[0074] In some embodiments, the present invention provides an air conditioner including a control device for the air conditioning element as described in any of the above embodiments. The air conditioner can be of various types, such as a wall-mounted air conditioner, a central air conditioning system, etc.
[0075] Figure 4The following are schematic flowcharts illustrating some embodiments of the control method for air conditioning components according to this disclosure, such as... Figure 4 As shown:
[0076] In step S401, control data is sent to the drive device through the main control chip.
[0077] In step S402, the control data is converted into a level control signal for the air conditioning element by the drive device, and the level control signal is sent to the voltage conversion device.
[0078] In step S403, the voltage control signal is converted using a voltage conversion device, and the converted voltage control signal is sent to the air conditioning element.
[0079] The control method for air conditioning components disclosed herein can reduce the port occupation of the main control chip by the air conditioning components, reduce costs and effectively improve the utilization efficiency of the main control chip; it can perform voltage conversion on the level control signal, adapt to the voltage requirements of different air conditioning components, and control a variety of air conditioning components.
[0080] In some embodiments, the driving device includes at least one driving chip; the driving chip converts control data into level control signals and sends them to the voltage conversion device.
[0081] By converting the level control signal through the driver chip, the occupancy of the main control chip by the air conditioning components can be reduced, effectively improving the utilization efficiency of the main control chip and enhancing the scalability of the drive device.
[0082] In some embodiments, there are multiple driver chips, which form a cascaded structure. The data input port of the first-level driver chip is connected to the main control chip, the data shift port of the previous-level driver chip is connected to the data input port of the next-level driver chip, and the signal input ports of each driver chip are connected to the main control chip. The signal input ports include latch ports, etc.
[0083] Figure 5 This is a schematic diagram illustrating the process of the main control chip sending control information in some embodiments of the control method for air conditioning components according to this disclosure, such as... Figure 5 As shown:
[0084] In step S501, the main control chip periodically sends control data to the primary driver chip according to a preset control interval.
[0085] When the driver chip receives control data, it sends the previously received control data to the data input port of the next-level driver chip through the data shift port.
[0086] By cascading multiple driver chips into a hierarchical extended architecture, the port usage of the main control chip is not increased, which effectively improves the utilization efficiency of the main control chip and enables synchronous control of multiple air conditioning components.
[0087] In step S502, after all control data has been sent, the main control chip sends an enable signal to the latch port of each driver chip.
[0088] Upon receiving an enable signal, each driver chip converts the latest received control data into a level control signal and sends the level control signal to the voltage conversion device.
[0089] By sending an enable signal, multiple air conditioning components can be controlled synchronously, ensuring synchronous control of multiple air conditioning components and improving the real-time performance and accuracy of the control.
[0090] In some embodiments, the voltage conversion device includes at least one voltage conversion chip; the voltage conversion chip is connected to at least one driver chip and at least one air conditioning element respectively; the voltage conversion chip performs voltage conversion processing on the received level control signal and sends the voltage-converted level control signal to the corresponding air conditioning element, which can adapt to the voltage requirements of different air conditioning elements, can control a variety of air conditioning elements, and improves the reliability of control.
[0091] The voltage conversion chip converts the first voltage of the level control signal into a second voltage, which is greater than the first voltage. This allows it to adapt to the high voltage of different air conditioning components and improve the compatibility of air conditioning component control.
[0092] The main control chip and the drive device are connected via a bus; the bus includes SPI bus, etc.; the length of the control data is at least one byte; the communication connection via the bus can realize high-speed data transmission, strong real-time performance and high reliability.
[0093] The control device and air conditioner for the air conditioning components in the above embodiments can reduce the port occupation of the main control chip by the air conditioning components, reduce costs and effectively improve the utilization efficiency of the main control chip. They can adapt to the voltage requirements of different air conditioning components, improve the compatibility and scalability of the control device, and can synchronously control multiple air conditioning components, improving the real-time performance and accuracy of the control. This also improves user satisfaction.
