Intelligent elevator capable of automatically calling, cancelling stoppage and warning when people is trapped

Abstract

The invention discloses an intelligent elevator and belongs to the intelligent control field of the elevator, and the elevator can automatically call, cancel stoppage and give an alarm when people is trapped in an elevator due to a fault. Upon a controller of a fingerprint access control machine judges out correct fingerprint information and gives out an opening command, the fingerprint information is transmitted to a data analyzing module through a 3G communicating module, the data analyzing module transmits the existing employee work floor information corresponding to the fingerprint information to a main elevator controller through RS 232 serial ports, when the employee work floor is more than one, the elevator controller gives out the command to start 'up and down keys' outside the elevator and related 'floor keys' inside the elevator for intelligent calling, and the employee can cancel calling and select the floor by again pressing the keys. A displayer is added with a sign of 'a surplus effective load for the elevator' and pressure sensors are arranged outside and inside the elevator, thereby avoiding the phenomenon of 'nobody enters into the elevator under stoppage', 'the elevator still stops in capacity load', ' the elevator still stops in idle load and without calling', and ' the elevator cannot give the alarm when people is trapped'.

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.
