[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0014] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0015] See Figure 1 As shown, this specific implementation adopts the following technical scheme: it includes an infrared receiving circuit 1, a central processing circuit 2, a serial communication circuit 3, and an infrared transmitting circuit 4; the infrared receiving circuit 1 receives the control signal of the infrared device and transmits it to the central processing circuit 2 for storage; the serial communication circuit 3 communicates with the external main system to directly transmit the control signal and the infrared signal to the central processing circuit 2 for learning and storage; the infrared transmitting circuit is controlled by the central processing circuit 2 to output the stored signal to multiple infrared devices for control.

[0016] Among them, the infrared receiving circuit 1 is composed of an infrared receiving head IR1, pin 1 of the infrared receiving head IR1 is connected to the positive pole of the power supply, pin 2 is grounded, and pin 3 is connected to the central processing circuit 2; when the infrared receiving head receives the infrared signal, the infrared signal is processed and output as a digital signal to pin 57 of the MCU.

[0017] Furthermore, the central processing circuit 2 is composed of an STM32F103RCT6 single-chip microcomputer; it communicates with the main system, receives infrared signals or sends infrared signals; when receiving an infrared learning instruction from the main system, the MCU stores the signal received by the infrared receiving circuit, and when it is necessary to send an infrared signal, the MCU can control the infrared transmitting circuit to transmit the infrared signal to the outside through pins 37, 38, 39, and 40, and can control one or more infrared transmitting circuits at the same time.

[0018] Furthermore, the serial communication circuit 3 communicates with the main system via the serial port to perform infrared learning or infrared transmission.

[0019] Furthermore, the infrared transmitting circuit 4 is composed of several infrared transmitting rods J and several transistors Q. The J1, J2, J3, and J4 ports are used for external infrared transmitting rods, and Q1, Q2, Q3, and Q4 control the transmitting rods; when it is necessary to control the external infrared device, the MCU controls the infrared pin to output high and low levels according to the infrared signal. When the MCU outputs a high level, the transistor Q1 is turned on and the infrared transmitting head is turned off. When the MCU outputs a low level, the transistor Q1 is turned off and the infrared transmitting head is lit.

[0020] The system operation workflow is as follows: the infrared receiving circuit is responsible for transmitting the received infrared signal to the MCU, and the MCU decodes the infrared signal and stores it in its own Flash. When the infrared device needs to be controlled, the MCU controls the on and off of the transistor through the pin. At this time, the infrared transmitter sends the infrared signal to the controlled device, thereby controlling the controlled device.

[0021] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
