every group the support component all includes a set of support frame (209), every group support frame (209) all include two, every support frame (209) bottom equal two fixedly connected with remove wheel (214), and every two support frames of every group (209) are fixed connection respectively in corresponding carriage (201) both sides interior table wall, every the equal fixedly connected with air pressure bar (210) of table wall in support frame (209) one side, every the output of air pressure bar (210) all slides and runs through corresponding support frame (209) inside bottom surface, every air pressure bar (210) output end fixedly connected with bottom plate (211), every the output surface cover of air pressure bar (210) is equipped with clamping ring (212), every clamping ring (212) both sides surface all rotates and is connected with cardboard (213).
2. The people flow early warning method based on artificial intelligence is applied to the people flow video acquisition device based on artificial intelligence, and comprises the following steps:
s1, equipment adjustment: the first motor (106) can be controlled, so that the first motor (106) can drive the bidirectional threaded rod (103) to rotate through a belt pulley and a belt, the rotating bidirectional threaded rod (103) can drive the moving frame (202) to perform position movement adjustment under the position limitation of the sliding groove, and the gear (203) can rotate along with the moving frame (202) in the position movement process under the position limitation of the rack (115), so that the use state of the supporting mechanism (2) is changed;
s2, fixing the position: after the first motor (106) is controlled to adjust the use state of the equipment according to the actual use condition, the air pressure rod (210) is controlled, the air pressure rod (210) can press the bottom plate (211) downwards, and when the bottom plate (211) is contacted with the bottom surface, the clamping plate (213) is pressed downwards by the pressing ring (212), so that the clamping plate (213) can effectively prevent the movable wheel (214) from rotating, and the equipment is stably placed at a specified use position;
s3, equipment control: when the flow of people is great, accessible control second motor (206) makes second motor (206) can drive supporting threaded rod (204) through conical gear (207) and rotate, and then adjusts the use height of first support, cooperates the self regulatory function of camera equipment body (205), makes the effective monitoring of flow of people under the different situations of equipment can accurately carry out.
