A control method for a tunnel intelligent air door system according to any one of claims 1 to 7, characterized in that: It includes a method for controlling the vehicle entry stroke and a method for controlling the vehicle return stroke; The vehicle entry travel control method includes: When a passing vehicle enters the tunnel from the tunnel entrance and passes the first infrared sensor, the central processor activates the gas detector to detect the methane / carbon monoxide concentration in the closed detection chamber and feeds back to the central processor; The central processor determines whether the received methane / carbon monoxide concentration is lower than the preset concentration safety limit; If not, the control opens the first air door and activates the sound and light alarm to prompt the passing vehicles to move forward, and the passing vehicles pass through the first air door and enter the closed inspection room; If yes, the axial flow fan is controlled to supply air to the closed detection room until the methane / carbon monoxide concentration is higher than the preset concentration safety limit, and the first air door is controlled to open, and the sound and light alarm is activated to prompt the passing vehicles to move forward, and the passing vehicles enter the closed detection room through the first air door; When a passing vehicle passes by the gas detector near the first air door, the central processor controls the closing of the first air door, and simultaneously starts the first pressure sensor and the second pressure sensor to detect the pressure of the closed detection chamber and the pressure between the second air door and the tunnel face respectively; The central processing unit calculates the corresponding pressure difference based on the two received pressure values; Determine whether the pressure in the closed test room is greater than the pressure between the second air door and the face, and determine whether the calculated pressure difference is greater than the set pressure difference; If yes, the second air door is controlled to be opened, and the passing vehicle passes through the second air door to the tunnel face, and the second air door is closed after a preset time; The carriage return stroke control methods include: When a passing vehicle starts from the tunnel face and passes the second infrared sensor, the central processor activates the gas detector to detect the methane / carbon monoxide concentration in the closed detection chamber and feeds back to the central processor; The central processor determines whether the received methane / carbon monoxide concentration is lower than the preset concentration safety limit; If not, the second air door is controlled to be opened and the sound and light alarm is activated to prompt the passing vehicles to move forward, and the passing vehicles pass through the second air door and enter the closed detection room; If yes, the axial flow fan is controlled to supply air to the closed detection room until the methane / carbon monoxide concentration is higher than the preset concentration safety limit, and the second air door is controlled to open, and the sound and light alarm is activated to prompt the passing vehicles to move forward, and the passing vehicles enter the closed detection room through the second air door; When a passing vehicle passes by the gas detector near the second air door, the central processor controls the closing of the second air door; When a passing vehicle passes by the gas detector near the first air door, the central processing unit controls the closing of the second air door, and controls the opening of the first air door after a preset time.

9. A terminal, characterized in that: include: processor; A memory for storing execution instructions of the processor; Wherein, the processor is configured to execute the method of claim 8.

10. A computer-readable storage medium storing a computer program, characterized in that: When the program is executed by a processor, the method according to claim 8 is implemented.
