Technical Field

The invention relates to the technical field of elevator detection systems, in particular to an elevator people trapping detection system.

Background

An elevator is a permanent transport device serving a plurality of specific floors in a building, the car of which runs on at least two rows of rigid rails which are perpendicular to the horizontal plane or have an inclination angle of less than 15 'with the vertical, and is also of the step type, tread plates are mounted on a track to run continuously, commonly known as an escalator or a moving sidewalk, and a fixed lifting device serving a specific floor, the vertical lifting elevator is provided with a car which runs between at least two rows of rigid guide rails which are perpendicular or have an inclination angle of less than 15', the size and the structural form of the car are convenient for passengers to get in or get out of or load and unload goods, and the vertical lifting elevator comprises the car, an elevator door and an emergency button.

The elevator is stranded in real life and the accident happens occasionally, and its concrete expression is that the car stops to certain floor, and the elevator door is closed or half closed state, and emergency button is used for stranded personnel emergency call for help and uses, but because the accident can make stranded personnel in a confused state of charge, probably forget to press emergency button to carry out wrong saving oneself.

Disclosure of Invention

The invention aims to provide an elevator trapping detection system, and provides a trapping detection system with an emergency button automatically triggered.

In order to solve the above problems, the present invention provides the following technical solutions: an elevator people trapping detection system comprises an elevator body, wherein the elevator body comprises a lift car, an elevator door and an emergency button, the lift car is provided with a sliding rail for the elevator door to slide, the sliding rail is provided with an infrared generator, the top of the lift car is provided with an infrared receiver matched with the infrared generator for use, the infrared receiver is in electric signal connection with a controller, and the lift car is provided with a gravity sensor; the car is equipped with the inner ring that surrounds emergency button, the car rotates and is connected with the outer loop that surrounds the inner ring, the car is equipped with and is used for driving outer loop pivoted motor, gravity inductor all with controller signal of telecommunication connection, the inner ring is equipped with the slip mouth, slip mouth sliding connection has the extrusion piece with the contact of emergency button, the thickness orientation of extrusion piece is bodiness gradually towards the direction of keeping away from the inner ring, the outer loop is the arc piece of fixedly connected with and extrusion piece butt still, the thickness of arc piece is crescent along clockwise.

The working principle and the beneficial effects of the invention are as follows: when the elevator door is not closed in the scheme, the infrared generator generates an infrared beam to be aligned to the infrared receiver, and then the infrared beam is received by the infrared receiver. When the elevator door is closed, the gravity sensor senses that the elevator car is occupied by a person, the elevator door blocks the infrared light beam, the infrared receiver does not receive the infrared light beam at the moment, the gravity sensor triggers the controller to time, and if the time exceeds certain limit time, the elevator is judged to be trapped by the person.

The controller then controls motor work this moment, and the motor drives the outer loop and rotates, and the outer loop drives inner wall connection's arc piece anticlockwise rotation, because the thickness of arc piece is crescent along clockwise, then the arc piece promotes the extrusion piece and removes towards the inner ring, and extrusion piece and emergency button contact, and the thickness orientation of extrusion piece is bodiness gradually away from the direction of inner ring, then the extrusion piece extrudees emergency button gradually for emergency button is pressed, then carries out emergency call.

Furthermore, the extrusion blocks are symmetrically arranged along the central axis of the inner ring. The emergency button is extruded through the extrusion blocks on the two sides, so that the emergency button can be pressed quickly.

Further, a rubber layer is arranged on the surface of the extrusion block. The rubber layer can wrap the surface of the extrusion block, so that the surface of the emergency button cannot be extruded and damaged by the extrusion block.

Furthermore, the electric signal of the controller is connected with an alarm and a sound box. When the controller judges that the elevator is trapped, the alarm is sent out through the alarm, and the sound box plays a safety prompt to prevent trapped people from forcibly opening the elevator door or performing other misoperation.

Further, the car is equipped with and is used for covering inner ring, outer loop, motor and emergency button's safety cover, the safety cover is equipped with the operation mouth relative with emergency button, the operation mouth is equipped with transparent protection film. The safety cover can cover above-mentioned each part for these parts can not expose in the environment, and the protection film can play interim guard action, avoids people's maloperation to press emergency button.

Further, the controller electric signal is connected with a height detection unit, and the height detection unit is specifically a laser range finder. Laser range finder can detect the stranded floor height of elevator for the rescue personnel can fix a position the elevator fast, conveniently rescues fast.

Furthermore, the controller is in electric signal connection with a wireless communication module, and the wireless communication module is in electric signal connection with a camera. The wireless communication module has high transmission speed, and can conveniently and quickly transmit the pictures shot by the camera to the outside.

Furthermore, the slide rail is provided with symmetrical clapboards, and the infrared generator is positioned between the clapboards at the two sides. In order to prevent personnel when the elevator transports goods, the maloperation is stepped on infrared emitter directly over, causes the emergency button false reaction, consequently sets up the baffle and blocks stepping on of this place slide rail.
