[0016] See Figure 1 As shown, this utility model provides a solar-powered windproof blanket, including a power supply device, a heating system, a control system, a leakage protection device, and a solar windproof blanket body. The heating system, the control system, and the leakage protection device are all installed on the solar windproof blanket body.

[0017] The heating system includes a heating element (RL); the control system includes an NE555 voltage regulator chip (IC), a digital control module, an OMEGA temperature sensing resistor (RT), a display module, and control buttons (K); the leakage protection device is a leakage protection resistor wire (R4).

[0018] The output terminal of the power supply device is electrically connected to the power pin (pin 8) of the NE555 voltage regulator chip (IC) and the power input terminal of the digital control module, respectively; the output pin (pin 3) of the NE555 voltage regulator chip (IC) is electrically connected to the signal input terminal of the digital control module; the signal output terminal of the digital control module is divided into two paths, one path is electrically connected to the signal input terminal of the OMEGA thermometer (RT), and the other path is electrically connected to the control terminal of the heating element (RL); the signal output terminal of the OMEGA thermometer (RT) is fed back to the trigger pin (pin 2) of the NE555 voltage regulator chip (IC); the signal input terminal of the display module is electrically connected to the output pin (pin 3) of the NE555 voltage regulator chip (IC), and the power supply terminal of the display module is electrically connected to the power supply device; the control button (K) is connected in parallel between the control pin (pin 4) of the NE555 voltage regulator chip (IC) and the power ground; the leakage protection resistor (R4) is connected in series between the power input terminal of the closed-loop control circuit and the common connection point of the control button (K).

[0019] The power supply device is used to supply power to the heating system, the control system, and the leakage protection device.

[0020] In this embodiment, at least one NE555 voltage regulator chip (IC) is provided, and multiple NE555 voltage regulator chips (ICs) are connected in parallel on the closed-loop control circuit.

[0021] In this embodiment, the display module includes a transistor and a filter transistor. The base of the transistor is electrically connected to the output pin (pin 3) of the NE555 voltage regulator chip (IC), the emitter of the transistor is grounded, and the collector of the transistor is electrically connected to the input terminal of the filter transistor.

[0022] In this embodiment, the power supply device includes a battery and a solar panel. The output end of the solar panel is electrically connected to the charging input end of the battery, and the output end of the battery supplies power to each power-consuming module.

[0023] In this embodiment, the solar windbreak body is made of pure cotton fabric.

[0024] In this embodiment, the power supply voltage range of the power supply device is +24.0V to +36V.

[0025] The positive output terminal of the power supply unit is connected to the power supply pin (pin 8) of the NE555 voltage regulator chip (IC) and the power input terminal of the digital control module, respectively. The negative output terminal of the power supply unit is connected to the circuit common ground to provide working power for the entire control system and heating system.

[0026] The output pin (pin 3) of the NE555 voltage regulator chip (IC) is electrically connected to the signal input terminal of the digital control module. The control signal generated by the NE555 voltage regulator chip is transmitted to the digital control module for signal processing.

[0027] The digital control module has two signal outputs. One output is electrically connected to the signal input of the OMEGA temperature sensor (RT) to send a detection signal to the temperature sensor. The other output is electrically connected to the control terminal of the heating element (RL) through the current limiting resistor (R2) to control the on / off state of the heating element.

[0028] The signal output of the OMEGA temperature sensing resistor (RT) is fed back to the trigger pin (pin 2) of the NE555 voltage regulator chip (IC) through the feedback resistor (R3), which converts the detected temperature signal into an electrical signal and feeds it back to the chip to form a closed-loop control.

[0029] The signal input terminal of the display module is connected to the output pin (pin 3) of the NE555 voltage regulator chip (IC) to receive control signals and display the current temperature status; the power supply terminal of the display module is connected to the power supply device, which provides the working power. The display module is composed of transistors and filter transistors to ensure stable display signals.

[0030] The control button (K) is connected in parallel between the control pin (pin 4) of the NE555 voltage regulator chip (IC) and the power ground. It is used to realize the device switching control and preset temperature adjustment functions. Pressing the button can switch between different preset temperature levels.

[0031] The leakage protection resistor (R4) is connected in series between the power input terminal of the closed-loop control circuit and the common connection point of the control button (K). When leakage occurs in the circuit and the current increases abnormally, the resistor (R4) will melt due to overheating from the overcurrent, cutting off the power supply to the entire control circuit and preventing leakage from causing a safety accident.

[0032] The working principle of this invention is as follows: The OMEGA temperature-sensing resistor (RT) has a temperature measurement range of 0 to +60℃ and an inherent temperature resolution of 0.5℃. Within the range of 0℃ to +40℃, the measurement error does not exceed 2℃, and within the range of 0 to +60℃, the measurement error does not exceed 5℃. When the temperature of the windshield is detected to be lower than the preset temperature, the resistance of the OMEGA temperature-sensing resistor (RT) changes. The feedback signal triggers the NE555 voltage regulator chip (IC) to output a high level. After receiving the signal, the digital control module controls the heating element (RL) to be powered on for heating. When the temperature reaches the preset value, the resistance of the OMEGA temperature-sensing resistor (RT) changes again. The feedback signal causes the NE555 voltage regulator chip (IC) to output a low level, and the digital control module cuts off the power supply to the heating element (RL), stopping heating and achieving automatic constant temperature control.

[0033] Multiple NE555 voltage regulator chips (ICs) can be set up. Multiple NE555 voltage regulator chips (ICs) are connected in parallel on the closed-loop control circuit, which can further improve the stability and accuracy of constant temperature measurement. The conversion efficiency of the temperature-controlled electric blanket is about 50%, and can reach up to 60%.

[0034] like Figure 2 The diagram shows a schematic of a solar-powered windproof blanket. It can be made by attaching a heating element (RL) or a built-in heating element (RL) to the main body 1 of the solar windproof blanket using Velcro. The solar panel 2 can be set in a three-fold form, which can be unfolded to charge when in use and folded for storage when not in use, making it very convenient to use.
