Bidirectional self-rotating intelligent entrance guard

Abstract

The invention discloses a bidirectional self-rotating intelligent entrance guard which comprises a bottom plate, a power unit and a rotating unit; the left side and the right side of the middle of theupper surface of the bottom plate are fixedly connected with the lower ends of two supporting plates correspondingly; the upper surfaces of the two supporting plates are fixedly connected with the left side and the right side of the middle of the lower surface of a mounting plate; the power unit comprises a gear, a motor, a gear ring, a bearing and a rotating door; the middles of the upper surface and the lower surface of the rotating door are rotationally connected with the middle of the upper surface of the bottom plate and the middle of the lower surface of the mounting plate correspondingly; an outer ring of the bearing is fixedly connected with the middle of the upper surface of the mounting plate; an inner ring of the bearing is fixedly connected with the lower surface of the gear ring; and the motor is mounted at the front side of the upper surface of the mounting plate. According to the bidirectional self-rotating intelligent entrance guard of the invention, only one person islimited to pass through the entrance guard each time, the situation of malicious following is prevented, the number of revolutions of the motor is irrelevant to the rotating angle of the rotating door, and the situation that the door is not rotated in place due to mechanical abrasion is prevented.

Description

technical field [0001] The invention relates to the technical field of intelligent access control, in particular to bidirectional self-rotating intelligent access control. Background technique [0002] The access control system, also known as the access management control system, is an intelligent management system that manages personnel to enter and exit. The summary is: manage who can enter and exit those doors at what time, and provide subsequent query reports, etc. Common access control systems include: password Access control system, non-contact card access control system, fingerprint iris palm biometric access control system, etc. The access control system has developed rapidly in recent years and is widely used in management control systems. At present, most of the existing access control systems are card swiping, door opening and Operations such as closing the door require a period of time between opening and closing the door for people to pass through, which easily ...

[0002] The access control system, also known as the access management control system, is an intelligent management system that manages personnel to enter and exit. The summary is: manage who can enter and exit those doors at what time, and provide subsequent query reports, etc. Common access control systems include: password Access control system, non-contact card access control system, fingerprint iris palm biometric access control system, etc. The access control system has developed rapidly in recent years and is widely used in management control systems. At present, most of the existing access control systems are card swiping, door opening and Operations such as closing the door require a period of time between opening and closing the door for people to pass through, which easily leads to the situation that someone maliciously follows, which seriously affects the safety performance of the access control. The door is opened and closed by stepping motor and gear transmission. This method mainly relies on the number of revolutions of the motor to control the rotation angle of the revolving door. However, the stepping motor is prone to lose steps and the gear transmission will appear gears during long-term use. Due to wear and tear, the revolving door does not rotate properly, affecting people's passage
