The general control information platform is a comprehensive intelligent traffic control platform, the host computer is intelligent communication equipment capable of collecting driving license and identity document image information and performing data interaction with the comprehensive intelligent traffic control platform through an App.
The working principle of the invention is as follows: when the handheld terminal is not needed, the operation wheel 3 is manually rotated, the operation wheel 3 drives the rhombic rotating piece 17 through the rotating shaft, so that the rhombic rotating piece 17 is vertically positioned between the first L-shaped rod 5 and the second L-shaped rod 6, and the first L-shaped rod 5 and the second L-shaped rod 6 are only under the tension action of the spring 18;
the upper shell 1 and the lower shell 13 are pressed on the fixing part 14 manually, when the upper shell 1 and the lower shell 13 approach the fixing part 14, the first connecting rod 12 and the second connecting rod 11 are separated towards two sides, the first connecting rod 12 and the second connecting rod 11 drive the first rack 9 and the second rack 8 to move towards one side in the separation process, the first rack 9 and the second rack 8 drive the piston rod 7 to extend into the handle part 2 in the movement process, the ratchet does not interfere the extending action of the piston rod 7 when the piston rod 7 extends into the handle part 2, meanwhile, the piston rod 7 drives the piston to move, the piston can pump air into the fixing part 14 in the movement process, the soft connection edge of the upper cover body and the lower cover body extends into the fixing part to form a sealed cavity, meanwhile, the upper cover body and the lower cover body continue to approach the fixing part 14, and the piston cylinder can continue to perform air pumping in the fixing part 14, therefore, negative pressure is formed in the sealed cavity, the soft connecting edges of the upper shell 1 and the lower shell 13 deform, and meanwhile, the ratchets at the end part of the piston rod 7 are meshed with the teeth of the first L-shaped rod 5 and the second L-shaped rod 6, so that the piston rod 7 can be prevented from returning, a sealed space is formed by the upper shell 1, the lower shell 13 and the fixing piece 14, dust can be prevented from entering, an internal host is prevented from being touched by mistake, and the host is prevented from being damaged by other factors;
when the practical handheld terminal is needed, the operating wheel 3 is manually rotated, the operating wheel 3 drives the rhombic rotating piece 17 through the rotating shaft, so that the rhombic rotating piece 17 is vertically aligned to the first L-shaped rod 5 and the second L-shaped rod 6, the first L-shaped rod 5 and the second L-shaped rod 6 are supported by two ends of the rhombic rotating piece 17 and are also pulled by the spring 18, the first L-shaped rod 5 and the second L-shaped rod 6 are ejected out by two ends of the rhombic rotating piece 17, so that the teeth of the first L-shaped rod 5 and the second L-shaped rod 6 are separated from the end part of the piston rod 7, the piston rod 7 is not limited by the first L-shaped rod 5 and the second L-shaped rod 6, a negative pressure effect exists in a space formed by the upper shell 1, the lower shell 13 and the fixing piece 14, and the space formed by the upper shell 1, the lower shell 13 and the fixing piece 14 is communicated with the piston cylinder, the negative pressure acts on the piston, and because the first L-shaped rod 5 and the second L-shaped rod 6 do not limit the piston rod 7, so that the piston can move toward the direction of the communication hole, and the air in the cylinder is injected into the space formed by the upper casing 1, the lower casing 13 and the fixing member 14, thereby breaking the negative pressure in the space of the upper casing 1, the lower casing 13 and the fixing member 14, because the upper shell 1 is lighter than the lower shell 13, the lower shell 13 moves downwards under the action of gravity, thereby driving the first connecting rod 12 and the second connecting rod 11 to move towards the middle part, the upper cover body is supported upwards in the process that the first connecting rod 12 and the second connecting rod 11 move towards the middle part, meanwhile, the first gear 16 and the second gear 15 drive the first rack 9 and the second rack 8 to move, the first rack 9 and the second rack 8 move to drive the piston to move towards the direction of the communicating hole provided with the communicating fixing piece 14;
by enabling the first connecting rod 12 and the second connecting rod 11 to be close to each other, the lower shell 13 can be located under the fixing part 14, the upper shell 1 is located over the fixing part 14, and in order to place drivers ' licenses, identity cards and other certificates conveniently, a transparent clamping piece used for limiting the drivers ' licenses and the identity cards can be arranged on the lower shell 13, so that the identity cards and the drivers ' licenses can be clamped and limited effectively without interference on image acquisition, meanwhile, an acquisition area can be planned through a convex strip on the lower shell 13, and the accuracy of image acquisition can be improved;
an inclined opening can be formed in the upper opening of the fixing piece 14, and the inclination angle of the upper shell 1 is adjusted at the same time, so that the upper shell 1 is always attached to the upper portion of the fixing piece 14, and meanwhile, two ends of the upper shell 1 are fixed to one end of the upper chute 4 through vertical rods, so that the upper chute 4 and the lower chute 10 are always kept parallel, and therefore the upper shell 1 cannot interfere with the viewing of a screen;
or go up casing 1 and also can set to the V font, 14 upper portion openings of mounting all the time with last casing 1 adaptation, casing 1 can guarantee to look over the screen from both sides on the V font and can not cause the interference, through rotating handheld terminal, can guarantee the shading effect of casing 1 to and avoid the rainwater to waft and influence on-duty efficiency on the screen.
