[0015] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the utility model is further detailed below with the drawings and examples.

[0016] REFERENCE Figure 1 And, Figure 1 It is a kind of based on the running flow diagram of the electric air outlet protection device of embedded system.

[0017] An electric air outlet protection device based on an embedded system is provided, which includes a first motor, an air outlet component, a driving module and a control module.

[0018] The air outlet component includes a motor gear and an air outlet fan blade, the motor gear is connected with the first motor, and the air outlet fan blade is connected with the motor gear;The control module is used to output a first control signal and a second control signal, the first control signal is used to control the first motor to rotate forward by a first angle, and the second control signal is used to control the first motor to rotate reversely by a second angle, the driving module is connected with the first driving motor, and the control module is connected with the driving module.

[0020] As a further improvement of the above technical solution, in some further specific examples, the driving module is a motor controller. A motor controller is an integrated circuit that actively controls the operation of a motor in a set direction, speed, angle, and response time. The motor controller can receive external instructions or signals, accurately adjust the input voltage and current of the motor through internal logic and control algorithms, and control the motor speed, direction, start, stop, and other motion parameters.

[0021] As a further improvement of the above technical solution, in some further specific examples, the control module includes an ECU. ECU (Electronic Control Unit) is the abbreviation of Electronic Control Unit, which is usually installed in cars or other machines for controlling various electronic systems. ECU can be regarded as a miniature computer, mainly composed of input circuit, microprocessor, output circuit, system power supply and program memory, etc. In the field of automobiles, ECU is responsible for receiving signals from various sensors such as engine speed, vehicle speed, temperature, pressure, etc., and then processing and analyzing these signals. Based on the built-in control program and algorithm, ECU will calculate the corresponding control instructions and send them to the actuators such as fuel injectors, ignition coils, throttle motors, etc. through the output circuit, so as to realize accurate control of the engine, transmission, brake system, body stability system, etc. The role of ECU in the car is crucial, which is directly related to the performance, fuel economy, emissions and driving safety of the car.

[0023] As a further improvement of the above technical solution, in some further specific examples, the second control signal is a LIN bus signal or a CAN bus signal. LIN bus, full name Local Interconnect Network (Local Interconnect Network), is a low-cost serial communication network defined for automotive distributed electronic systems. LIN bus is based on SCI (UART) data format, and adopts single master controller / multiple slave device mode for communication. In this mode, the master controller is responsible for managing and scheduling data transmission on the bus, while the slave devices respond according to the instructions of the master controller. LIN bus has the characteristics of low cost, low power consumption, reliability, etc., and is particularly suitable for application scenarios that do not have high requirements on network bandwidth, performance or fault tolerance function.

[0024] CAN(Controller Area Network) bus is a kind of serial communication protocol, CAN bus is a kind of serial communication network which effectively supports distributed or real-time control. Its characteristics include high reliability, real-time and strong anti-interference ability. CAN bus uses differential signals (CAN_H and CAN_L) for data transmission, which has strong anti-interference ability in the electrical noise environment. In addition, CAN bus also supports the communication mode of multiple master devices, that is, each node in the network can actively send data without the management of the central controller.

[0025] The first control signal and the second control signal can also be other types of bus signals.
