An intelligent elevator that can automatically call and cancel the stop of the elevator and automatically alarm when people are trapped

Abstract

An intelligent elevator that can automatically call and cancel the stop of the elevator and automatically alarm when people are trapped. The invention can realize automatic call and cancel the stop of the elevator, and automatically send out an alarm when the elevator fails and stops, and belongs to the field of elevator intelligent control. After the controller of the fingerprint access control machine judges that the fingerprint information is correct, the 3G communication module sends the fingerprint information to the data analysis module at the same time as issuing the door opening command. When the employee's working floor is greater than 1, the elevator controller sends an instruction to light up the "up and down buttons" outside the elevator and the corresponding "floor buttons" in the car to realize intelligent elevator calling. Press the button again to cancel the call and select the floor. By increasing the number of "elevator remaining payload" on the display and installing pressure sensors outside the elevator and inside the car, it is possible to avoid the occurrence of "the elevator stops and no one gets on", "the elevator stops when it is fully loaded", "the elevator is empty and there is no Outbound calls also stop", "the elevator is trapped and people do not call the police" and other phenomena.

Description

Technical field [0001] The invention relates to a control device based on a fingerprint machine / swipe card machine, a 3G communication module, a data analysis module, a pressure sensor, an electronic display, and an elevator data acquisition module. It automatically sends out an alarm when a person is trapped, and belongs to the field of elevator intelligent control. Background technique [0002] At present, the common attendance method is fingerprint attendance or ID card attendance. Taking fingerprint attendance as an example, when an employee enters an office building or an office building, he presses his own fingerprint and compares it with the pre-stored fingerprint in the fingerprint identification module of the fingerprint access control machine. Yes, after confirming the employee information, the back-end controller controls to open the door. After entering the building, employees press the "up and down keys" of the elevator and wait for the elevator. In this way, ...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the existing passenger elevator, the following situations may occur: (1) After the passenger presses the "up and down key", he leaves halfway for some reason; (2) after the passenger presses the "up and down key", the elevator arrives After opening the door at this floor, it is found that the remaining load of the elevator is lower than the weight of a normal person and there is no passenger in the car who chooses to stop the elevator at this floor; (3) Several friends wait for the elevator together, and when the elevator arrives, it is found that the remaining load is not enough. Several people enter the car at the same time (4) There is no one in the car, but the floor button is still pressed; (5) There are people in the car, but the elevator door is set It has not been opened within a certain period of time, that is, an elevator trapped accident occurs

The first four situations cause the "empty running" and "empty stop" of the elevator, which not only wastes energy, but also increases the mechanical wear of the elevator and wastes the time of passengers.

In the fifth situation, when the elevator is trapped, the passengers are often panicked and do not send out the alarm and distress signal in time. The rescuers cannot rescue the passengers in the first time, causing huge psychological pressure to the passengers and causing bad social impact.
