In a preferred embodiment, referring to fig. 1, the opening detection system of the engine activity gate of the present embodiment includes a processor 10, an angle detection module 20, a stepping motor 30 and an activity gate 40, wherein the processor 10 is connected to and drives the stepping motor 30 to rotate. The stepping motor 30 is in transmission connection with the movable door 40, and the stepping motor 30 can drive the movable door 40 to move so as to adjust the opening degree of the movable door 40. The stepping motor 30 is in transmission connection with the angle detection module 20, the stepping motor 30 can drive the angle detection module 20 to move, and the angle detection module 20 generates a corresponding detection signal after moving. The processor 10 is connected to the angle detection module 20, and acquires the detection signal generated by the angle detection module 20.
The working principle of the system for detecting the opening of the movable door of the engine is as follows: when the stepping motor 30 rotates, the movable door 40 and the angle detection module 20 are synchronously driven, so that the movable door 40 and the angle detection module 20 are driven to synchronously link, and the variation of the angle detection module 20 can reflect the opening degree of the movable door 40. The processor 10 or a memory connected to the processor 10 stores therein a correspondence between the detection signal and the shutter door, and the correspondence between the detection signal and the shutter door opening is a correspondence between the detection signal and the current opening of the shutter door 40 of the engine. After the processor 10 obtains the detection signal generated by the angle detection module 20, the opening degree of the movable door corresponding to the detection signal is searched according to the corresponding relationship between the detection signal and the opening degree of the movable door, and then the current opening degree of the movable door is obtained.
The stepping motor drives the engine movable door and simultaneously drives the angle detection module to move, synchronous linkage of the engine movable door and the angle detection module is achieved, and the opening degree of the engine movable door is obtained through detection signals of the angle detection module.

The voltage dividing output terminal of the slide rheostat 201 is connected with the processor 10. Alternatively, the rheostat 201 may be connected in series with a voltage divider, and the processor 10 may collect a detected voltage value at the rheostat 201 or the voltage divider.
The working principle of the system for detecting the opening of the movable door of the engine is as follows: when the stepping motor 30 rotates, the sliding ends of the movable door 40 and the sliding rheostat 201 are synchronously driven, so that the sliding ends of the movable door 40 and the sliding rheostat 201 are synchronously driven to be linked, the access resistance of the sliding rheostat 201 changes, the resistance voltage division changes due to the access resistance change, and the detection voltage value changes, so that the detection voltage value can reflect the opening degree of the movable door 40. The processor 10 or a memory connected to the processor 10 stores a correspondence between a voltage and a shutter opening, which is a correspondence between a detected voltage value of the slide rheostat 201 and a current opening of the shutter 40 of the engine. After the processor 10 obtains the detection voltage value generated by the sliding rheostat 201, the opening degree of the movable door corresponding to the detection voltage value is searched according to the corresponding relation between the voltage and the opening degree of the movable door, and then the current opening degree of the movable door can be obtained.

Alternatively, the magnetic component 2022 may be mounted on a shaft of the movable door 40, such as a throttle shaft or a choke shaft, and the rotation of the movable door 40 drives the movable door 40 to rotate, and thus the magnetic component 2022 to rotate or move. The linear hall sensor 2021 is fixedly installed on the engine, the processor 10 is connected with the linear hall sensor 2021, the first end of the linear hall sensor 2021 is connected with the voltage power supply end, the second end of the linear hall sensor 2021 is grounded, and the processor 10 is connected with the voltage output end of the linear hall sensor 2021.
The working principle of the system for detecting the opening of the movable door of the engine is as follows: when the stepping motor 30 rotates, the movable door 40 and the magnetic component 2022 are synchronously driven, so that the movable door 40 and the magnetic component 2022 are driven to be synchronously linked, and the rotation or movement of the magnetic component 2022 causes the output voltage of the linear hall sensor 2021 to change, so that the detection voltage value of the linear hall sensor 2021 can reflect the opening degree of the movable door 40. The processor 10 or a memory connected to the processor 10 stores a correspondence relationship between the voltage and the movable door opening, which is a correspondence relationship between the detected voltage value of the linear hall sensor 2021 and the current opening of the movable door 40 of the engine. After the processor 10 obtains the detection voltage value of the linear hall sensor 2021, the opening degree of the movable door corresponding to the detection voltage value is searched according to the corresponding relationship between the voltage and the opening degree of the movable door, and then the current opening degree of the movable door is obtained.
The stepping motor drives the engine movable door and the magnetic component 2022 to move at the same time, so that the synchronous linkage of the engine movable door and the magnetic component 2022 is realized, and the opening degree of the engine movable door is obtained by detecting a detection voltage value of the linear hall sensor 2021.

Alternatively, the encoder disk 2032 may be mounted on a shaft of the movable door 40, such as a throttle shaft or a choke shaft, and the movable door 40 is rotated to rotate the movable door 40, and thus the encoder disk 2032 is rotated or moved. The first terminal of the photoelectric encoder 2031 is connected to a voltage supply terminal, the second terminal of the photoelectric encoder 2031 is grounded, and the processor 10 is connected to the photoelectric encoder 2031.
The working principle of the system for detecting the opening of the movable door of the engine is as follows: when the stepping motor 30 rotates, the movable door 40 and the encoder disk 2032 are synchronously driven, so that the movable door 40 and the encoder disk 2032 are synchronously driven, and the output voltage of the photoelectric encoder 2031 changes due to the rotation of the encoder disk 2032, so that the detected voltage value can reflect the opening degree of the movable door 40. The processor 10 or a memory connected to the processor 10 stores a correspondence relationship between the voltage and the movable door opening, which is a correspondence relationship between the detected voltage value of the photoelectric encoder 2031 and the current opening of the movable door 40 of the engine. After the processor 10 obtains the detected voltage value of the photoelectric encoder 2031, the current opening degree of the movable door can be obtained by searching the opening degree of the movable door corresponding to the detected voltage value according to the corresponding relationship between the voltage and the opening degree of the movable door.

If the difference is not the same, the processor 10 controls the stepping motor 30 to rotate, and the movable opening is adjusted to be the same as the movable opening corresponding to the engine state. That is, the processor 10 controls the stepping motor 30 to rotate and simultaneously drives the angle detection module 20 to move, the processor 10 collects the detection signal generated by the angle detection module 20 in real time, searches the opening degree of the movable door corresponding to the detection signal according to the corresponding relationship between the detection signal and the opening degree of the movable door, and when the opening degree of the movable door is consistent with the opening degree of the movable door corresponding to the engine state, the stepping motor 30 stops rotating. The movable opening degree is made to be consistent with the movable opening degree corresponding to the engine state through feedback adjustment, and normal work of the engine is guaranteed.
