Description

Technical Field

[0001] The present invention relates to the technical field of remote control circuits, and particularly to a remote control circuit for air-conditioning clothing.

Background Art

[0002] An air-conditioning clothing is a type of clothing with a cooling and heat dissipation tool such as a small fan installed inside. It can accelerate the evaporation of sweat, absorb the heat on the human body surface, cool the human body, and make people feel cool and comfortable. For example, it is an air-cooled type of air-conditioning clothing disclosed in Chinese Utility Model Patent CN202322056720.7. Such products can be widely applied to outdoor work groups such as traffic police, border guards, oilfield workers, railway workers, and warehouse handlers. Conventional air-conditioning clothing is usually controlled in a wired manner where a controller is fixed to the clothing or installed in a pocket as a movable end, and the controller and each electrical component of the air-conditioning clothing are connected by wires. When adopting such a wired control method, it is necessary to install connecting wires, which not only makes the structure more complex but may also affect the convenience of use due to the presence of the wires. Attempts have also been made to introduce a remote control to control the air-conditioning clothing, but conventional remote control circuits are complex, costly, and difficult to design.

Summary of the Invention

[0003] In view of the drawbacks existing in the prior art, the present invention provides a remote control circuit for air-conditioning clothing that can achieve remote control of air-conditioning clothing, has a simpler circuit structure, lower cost, and is easier to design.

Means for Solving the Problems

[0004] To solve the above technical problems, this invention adopts the following technical solution. The air-conditioned clothing remote control circuit includes a battery, a master MCU U1 and a wireless transmission chip U2. The wireless transmission chip U2 is connected to the master MCU U1, buttons are connected to the master MCU U1, and an antenna ANT is connected to the wireless transmission chip U2. The buttons include one on / off button S1, one output voltage increase button S2, and one output voltage decrease button S3. Buttons S1-S3 are each connected to the master MCU U1. The antenna ANT is connected to the wireless transmission chip U2 via an LC oscillator circuit, and a filtering circuit and a crystal oscillator Y1 are further connected to the wireless transmission chip U2.

[0005] The master MCU U1 uses a remote control master chip with model number SC8F07X. Buttons S1-S3 are connected to pins 6-8 of the master MCU U1, respectively. The wireless transmitter chip U2 is connected to pin 15 of the master MCU U1, and pin 1 of the master MCU U1 is connected to a 3V DC power supply.

[0006] The wireless transmitter chip U2, model number CMT2119A, is connected to pin 15 of the master MCU U1 via pin 4. The antenna ANT and filtering circuit are connected to pin 3 of the wireless transmitter chip U2, and the crystal oscillator Y1 is connected to pin 6 of the wireless transmitter chip.

[0007] LED1-LED3, which are light-emitting diodes for operation indicator lamps, are connected to pins 14-12 of the master MCU U1 via resistors R2-R4, respectively.

[0008] The master MCU U1 has pin 9 grounded via resistor R7, and pin 16 directly grounded.

[0009] The fifth pin of the wireless transmitter chip U2 is connected to a 3V DC power supply via resistor R8 and to ground via capacitor C3. [Effects of the Invention]

[0010] This invention enables long-range (1-10 meter) and contactless on / off and shift adjustment of air-conditioned clothing using a remote control, eliminating the limitations imposed by wired control systems and making it more convenient to use. Furthermore, the overall structure of the remote control circuit is very simple, consisting of only two chips: an MCU and a wireless transmitter. The accompanying peripheral circuits are also simple, significantly reducing the cost of the remote control and the complexity of the circuit design. [Brief explanation of the drawing]

[0011] [Figure 1] This is a circuit diagram illustrating the principle of the present invention. [Modes for carrying out the invention]

[0012] The present invention will be further described below with reference to the attached drawings.

[0013] Referring to Figure 1, in this embodiment, the air-conditioned clothing remote control control circuit includes a battery, a master MCU U1, and a wireless transmission chip U2. The wireless transmission chip U2 is connected to the master MCU U1, buttons are connected to the master MCU U1, and an antenna ANT is connected to the wireless transmission chip U2. The buttons include one on / off button S1, one output voltage increase button S2, and one output voltage decrease button S3. Buttons S1-S3 are each connected to the master MCU U1. The antenna ANT is connected to the wireless transmission chip U2 via an LC oscillator circuit, and a filtering circuit and a crystal oscillator Y1 are further connected to the wireless transmission chip U2.

[0014] The master MCU U1 can use a remote control master chip with model number SC8F07X (or a remote control control chip with similar functionality), buttons S1-S3 are connected to pins 6-8 of the master MCU U1 respectively, the wireless transmitter chip U2 is connected to pin 15 of the master MCU U1, and pin 1 of the master MCU U1 is connected to a 3V DC power supply.

[0015] The wireless transmitter chip U2, model number CMT2119A, is connected to pin 15 of the master MCU U1 via pin 4. The antenna ANT and filtering circuit are connected to pin 3 of the wireless transmitter chip U2, and the crystal oscillator Y1 is connected to pin 6 of the wireless transmitter chip.

[0016] LED1-LED3, which are light-emitting diodes for operation indicator lamps, are connected to pins 14-12 of the master MCU U1 via resistors R2-R4, respectively.

[0017] The master MCU U1 has pin 9 grounded via resistor R7, and pin 16 directly grounded.

[0018] The fifth pin of the wireless transmitter chip U2 is connected to a 3V DC power supply via resistor R8 and to ground via capacitor C3.

[0019] When in use, pressing and holding button S1 in the middle of the remote control causes pin 6 of the master MCU (microprocessor) U1 to receive a high level "ON" signal close to 3V. The MCU compiles and encrypts this "ON" signal and transmits it to the wireless transmission chip U2 (CMT2119A). U2 transmits this ON signal in 433MHz (315MHz in Japan) carrier wave format, thereby controlling the air-conditioned clothing and turning on the heat dissipation cooling function.

[0020] To turn it off, press and hold button S1 in the middle of the remote control. Pin 6 of the MCU will receive an "off" signal voltage close to 3V. The MCU compiles and encrypts this "off" signal and transmits it to the wireless transmission chip U2. U2 transmits this off signal in 433MHz (315MHz in Japan) carrier wave format, thereby controlling the air-conditioned clothing and turning off the heat dissipation cooling function.

[0021] When buttons S2 / S3 are pressed and held while the device is ON, pins 7 / 8 of the MCU receive high-voltage signals of "voltage rise" / "voltage drop" that are close to 3V and finely tuned. The MCU compiles and encrypts these "voltage rise" / "voltage drop" signals and transmits them to U2. U2 then transmits these "voltage rise" / "voltage drop" signals in 433MHz (315MHz in Japan) carrier wave format. In the air-conditioned clothing, the power supply equipped with a receiving function receives the signal, decodes it, and then controls the power on / off, thereby controlling the voltage rise (which increases the fan speed) and voltage drop (which decreases the fan speed).

[0022] Although the present invention has been described in detail above, what has been described is merely a relatively good embodiment of the present invention and does not limit the scope of implementation. That is, if the scope of the application is equally varied and modified, all of these should fall within the scope of the present invention.
