[0031] With the development of science and technology, it affects all aspects of people's lives. Air conditioners have become more intelligent and life has become more technological. As the control center of the air conditioner, the wireless remote control plays an important role. However, in the existing technical solutions, the wireless remote control can only operate the operating status of the air conditioner, and the display screen of the air conditioner can simply display the current operating status, but it is impossible to understand the specific operating status of the air conditioner.

[0032] Among the existing market products, there are two technical solutions for remote control. The first is to control the air conditioner through one-way communication between the wireless remote control and the air conditioner. The user issues key commands on the wireless remote control, and the wireless remote control sends the commands to the air conditioner, thereby changing the operating state of the air conditioner, but cannot obtain the operating information of the air conditioner; the second is to control the air conditioner through two-way communication between the wired remote control and the air conditioner. The user issues key commands on the wired remote control, and the commands are sent to the air conditioner through a wired connection, thereby changing the operating state of the air conditioner or obtaining the operating information of the air conditioner, but it limits the user's range of movement and usage scenarios. Both of the above solutions have shortcomings. If the two solutions are combined, the wireless remote control and the wired air conditioner can communicate with the air conditioner in two directions. However, the air conditioner operating information needs to be checked on the wired remote control, which cannot really solve the problem and has a higher production cost.

[0033] Based on this, the embodiments of the present application provide a communication circuit, a circuit board, and a remote control for a wireless remote control, which can not only control the air conditioner, but also obtain the operating status of the air conditioner, thereby realizing two-way communication between the wireless remote control and the air conditioner.

[0034] A communication circuit, a circuit board, and a remote controller of a wireless remote controller are described below with reference to the accompanying drawings.

[0035] Reference Figure 1-6 As shown, Figure 1 is a module schematic diagram of a communication circuit of a wireless remote controller provided in an embodiment of the present application, Figure 2 is a circuit diagram of a control module provided in an embodiment of the present application, Figure 3 is a circuit diagram of a sending module provided in an embodiment of the present application, Figure 4 is a circuit diagram of a receiving module provided in an embodiment of the present application, Figure 5 is a circuit diagram of a circuit module provided in an embodiment of the present application, Figure 6 This is a circuit diagram of a key module provided in an embodiment of the present application.

[0036] The embodiment of the present application provides a communication circuit 100 of a wireless remote controller, including: a control module 110, a key module 120, a sending module 130, a receiving module 140 and a power module 150, wherein the control module 110 is connected to the key module 120, the sending module 130, the receiving module 140 and the power module 150 respectively;

[0037] Among them, the button module 120 is connected to the control module 110 through the signal input end, the sending module 130 includes a first transistor Q1 and a signal transmitter, the control module 110 is connected to the signal transmitter through the first transistor Q1, the receiving module 140 includes a second transistor Q3 and a signal receiver, the control module 110 is connected to the signal receiver through the second transistor Q3, and the power module 150 is connected to the control module 110 through the power input end.

[0038] It should be noted that the control module 110 includes a control chip, and the control chip model is preferably S1C17W23F. The key module 120 is connected to the control module 110 through the signal input terminal to receive the key input signal and perform corresponding control operations. The power module 150 is connected to the control module 110 through the power input terminal to provide power support for the entire circuit. The control module 110 is connected to the signal transmitter in the sending module 130 through the first transistor Q1. The key input signal is processed by the control module 110 to form a remote control command. The control signal transmitter sends the remote control command to the air conditioner. The control module 110 is connected to the signal receiver of the receiving module 140 through the second transistor Q3. After sending the command, the control module 110 controls the receiving module 140 to enter the information receiving state, thereby realizing two-way communication between the wireless remote control and the air conditioner.

[0039] In one embodiment of the present application, the user uses the key module 120 of the wireless remote control, and the key module 120 transmits the key operation to the control module 110 through the signal input end. After receiving the key signal, the control module 110 generates a wireless remote control instruction and controls the sending module 130 according to the instruction. The sending module 130 sends the instruction of the wireless remote control through the signal transmitter. After the sending is completed, the control module 110 receives the reply information of the external air conditioner through the receiving module 140.

[0040] It can be understood that through two-way communication, two-way communication between the wireless remote control and the air conditioner is achieved. This means that the remote control can send instructions to the external device and receive feedback signals from the external device. The effect is that the remote control can fully control and monitor the external device, enhance the interactivity and feedback between the user and the device, and improve the practicality and convenience of the remote control.

[0041] In some embodiments, the sending module 130 further includes a first resistor R1, the control module 110 is connected to the base of the first transistor Q1 through the first resistor R1, the signal transmitter is connected to the collector of the first transistor Q1, and the emitter of the first transistor Q1 is connected to the ground.

[0042] It should be noted that the control module 110 is connected to the base of the first transistor Q1 via the first resistor R1, allowing the control module 110 to accurately control the on and off of the first transistor Q1, thereby controlling the working state of the signal transmitter.

[0043] In one embodiment of the present application, the control module 110 can change the working state of the first transistor Q1 by applying different voltages or currents to the first transistor Q1. When the signal transmitter is required to output a signal, the control module 110 will provide an appropriate signal to the first transistor Q1 to turn it on, so that the current flows through the first transistor Q1 to reach the signal transmitter, activate the signal transmitter and generate a corresponding signal. When it is necessary to stop the signal transmitter from outputting a signal, the control module 110 will change the working state of the first transistor Q1 to cut off, thereby blocking the current from flowing to the signal transmitter and stopping the signal transmitter. In this way, the control module 110 can accurately control the output of the signal transmitter by controlling the working state of the first transistor Q1, thereby realizing flexible regulation and control of the signal transmission process.

[0044] In some embodiments, the receiving module 140 also includes a second resistor R2 and a third resistor R3, the control module 110 is connected to the base of the second transistor Q3 through the second resistor R2, the signal receiver is connected to the collector of the second transistor Q3 through the third resistor R3, and the emitter of the first transistor Q1 is connected to the power supply input terminal.

[0045] It should be noted that the output pin of the control module 110 is connected to the base of the second transistor Q3 via the second resistor R2 to control the conduction state of the second transistor Q3.

[0046] In one embodiment of the present application, the control module 110 outputs a specific voltage signal to the second resistor R2, causing the base voltage of the second transistor Q3 to change. The base voltage change of the second transistor Q3 causes it to be turned on or off, affecting the working state of the signal receiver. When the second transistor Q3 is turned on, the signal receiver is in a working state, receiving and processing signals. When the second transistor Q3 is turned off, the signal receiver may stop working or enter a low-power standby state to save energy and extend the life of the device. The control module 110 can accurately control the conduction state of the second transistor Q3 by adjusting the size and frequency of the output voltage signal, thereby achieving precise control of the signal receiver.

[0047] In some embodiments, the communication circuit 100 further includes an LCD module 160 , and the control module 110 is connected to the LCD module 160 .

[0048] It should be noted that the LCD module 160 usually refers to a liquid crystal display module, including a liquid crystal display screen, which can display text, images and other information, and based on the reply information fed back by the air conditioner, display the air conditioner maintenance status, air conditioner operation status, perceived temperature, indoor humidity, outdoor temperature, today's electricity bill, this month's electricity bill and last month's electricity bill and other air conditioner operation information.

[0050] It should be noted that by adjusting the resistance of the fourth resistor R4, the conduction state of the third transistor Q2 can be controlled, thereby adjusting the brightness of the LED light and realizing the brightness adjustment function of the backlight. The backlight brightness is adjusted according to the ambient light conditions to improve the visibility and comfort of the LCD display screen, so that it can be clearly seen under different lighting conditions.
