[0046] S1. According to the venue use reservation information, determine the set parameters. The set parameters include the ventilation mode, the air supply volume, the wind speed and the temperature, and re-set the parameters according to the environmental parameter information: drive the control slide bar 203 to move by using the control electric cylinder 501, and the control slide bar 203 drives the connecting hinge 204 to move. During this period, the connecting hinge 204 cooperates with the control swing rod 202 to drive the angle of the horizontal louver 201 to rotate, thereby opening the ventilation opening outside; drive the control worm 403 to rotate by using the control motor 404, the control worm 403 drives the control worm gear 402 to rotate, and the control worm gear 402 drives the vertical louver 401 to rotate, so as to open the ventilation opening inside, and further control the indoor wind direction.

[0047] S11), If it is detected that natural ventilation is sufficient and the wind force is appropriate, set the opening and closing ratio of the natural ventilation opening to 100%. At the same time, use the flow control electric cylinder 703 to drive the closing valve plate 704 to move and close the two openings on one side of the active air control channel 7;

[0048] S12), If it is detected that there is no wind or the wind force is too strong, use the active air control channel 7 to supply air. Open the horizontal louvers 201 and close the vertical louvers 401. The flow control electric cylinder 703 opens the lower closing valve plate 704, and starts the main control air pump 705 on the leeward side to extract air and input it into the room. Use the main control air pumps 705 installed on both sides that are neither directly facing nor directly against the wind direction to discharge the excess air to maintain the indoor air pressure;

[0049] S13), When it is detected that the temperature in the room is lower than the threshold value, use the heater 702 to heat the air flowing into the room. Close the lower closing valve plate 704 through the flow control electric cylinder 703 and open the upper closing valve plate 704, so that the air can flow through the heater 702 to heat the air and increase the indoor temperature; On windy days and in winter, raise the airtight partition 602 through the program-controlled opening and closing electric cylinder 601 to close the inner louver frame 4 to improve the airtightness;

[0050] S2. Adopt an artificial intelligence algorithm to automatically adjust parameters such as the opening and closing duty cycle of the natural ventilation opening, ventilation mode, air supply volume, wind speed, and return air volume according to the environmental parameters and weather information in the venue, and achieve precise ventilation for automatic control;

[0051] S21), The system collects the indoor environmental parameters of the building through the data induction unit;

[0056] (1)Determine nodes and relationships based on the collected data;

[0057] (2)Determine the conditional probability of relationships according to the data;

[0058] (3)Judge whether the training data is sufficient. If so, proceed to the next step; if not, re-determine the relationships;

[0059] (4)Establish an initial Bayesian network;

[0062] Embodiment 2:

[0063] Based on Embodiment 1, as Figure 1 shown, the position of the selection hole 701 is generally sealed with a sealing cover;

[0064] Since the high indoor temperature in summer will affect human activities, especially various sports events, it will cause the body temperature to be too high and affect health; if there is an air conditioner installed indoors, the air conditioner can be directly selected;

[0065] However, according to needs, a cooling function can be added. The selection hole 701 is provided with a pipeline directly connected to an air conditioning device or a compressor and other devices to deliver cold air into the room, so as to reduce the indoor temperature, which is mainly applicable in summer;

[0066] During this process, the vertical louvers 401 can be selected to be opened, and the air is supplied through the interval positions of the vertical louvers 401, and the flow direction can be controlled.

[0067] Embodiment 3:

[0068] Based on Embodiment 1, the size of the ventilation channel 2 can be adjusted and customized according to needs;

[0069] When installing the ventilation channel 2, open a through groove in the direction outside the stadium 1, drill holes and install expansion bolts on the periphery of the indoor side of the through groove, and use the expansion bolts to fixedly install the positioning frame 3. At the same time, the positioning frame 3 is sleeved outside the ventilation channel 2 and fixed by bolt connection, so as to fix the positioning frame 3 and the ventilation channel 2;

[0070] According to different types of venues, this equipment can be installed in this way.
