A gate access control mechanism

Abstract

The invention discloses a gate access control mechanism which comprises a portal and a shear door arranged on the portal, wherein the shear door is driven to act through a first driving mechanism and a second driving mechanism; the first driving mechanism realizes reciprocating swing of the shear door; the second driving mechanism realizes position retaining or speed reduction of the shear door; the first driving mechanism and the second driving mechanism are connected with a control system of the shear door; and the control system judges whether a person is pinched or a passenger rushes the gate according to the access logics and controls the first driving mechanism or the second driving mechanism to execute the action. The gate access control mechanism is simultaneously provided with the first driving mechanism and the second driving mechanism, so that the shear door is controlled, the gate rushing resistance and the anti-pinching force of the door-closing motion are separated, even if the access logics is misjudged, the door plate is only kept at a passenger impact force position, and the secondary injury of the human body is avoided; and moreover, the requirements on the first driving mechanism can be reduced, and the overall cost is reduced.

Description

technical field [0001] The invention relates to a gate passage control mechanism. Background technique [0002] The blocking force of the scissor door in the existing gate is realized by the driving mechanism of the movement of the scissor door panel. external force. During the closing process of the scissor door, it is necessary to generate a small anti-pinch force to reduce the external force damage to normal passers-by, and to generate a large barrier resistance to resist the passage of the barrier. In the prior art, in order to achieve better anti-pinch and anti-break-through functions, the actuator needs to be able to generate great resistance, and at the same time, the door panel is made of soft material to buffer the damage caused by the impact force to passers-by. [0003] During the closing process, the scissor door panel must generate both a small anti-pinch force and a huge resistance to breaking through the gate. The specific implementation of the anti-pinch mo...

Problems solved by technology

Even if the judgment of the traffic logic is reliable, in order to generate greater resistance to break-in and prevent passengers from breaking in without a ticket, the maximum torque of the drive mechanism is required to be very high, and the normal door opening and closing movement only needs to overcome the gravity moment of the door panel itself. It will undoubtedly increase the difficulty of selecting the first actuator and increase the cost of the whole machine
