Abstract
The utility model relates to an elevator failure alarm system, in particular to an elevator help-calling alarm device for people trapped in an elevator. A failure alarm processing unit is electrically connected with an alarm bell button of the elevator, and a power source of the failure alarm processing unit is connected with a main supply through an uninterrupted power supply (UPS). An output end of the failure alarm processing unit is in communication link with a monitoring room client terminal through a network sending module. The failure alarm processing unit comprises an 89S5 series single chip microcomputer and a MAX 485 communication module. The elevator help-calling alarm device has the advantages that when an elevator failure occurs, passengers in the elevator can directly send information of being trapped to the remote monitoring room client terminal through the alarm button, and therefore the elevator failure can be removed timely, and a larger safety accident can be avoided.
Description
Technical field
The utility model relates to a kind of elevator faults warning, particularly a kind of elevator malfunction rescue alarm device.
Background technology
When elevator offers convenience to people, a lot of hidden danger also lie dormant, elevator faults is of a great variety, and when elevator faults occurring and cause in the stranded elevator of occupant, the occupant need to notify extraneous to obtain relief, general alarm bell by phone or elevator, and the alarm bell of elevator is installed in one deck position, and closing the people is that stranded passenger presses Alarm bell's switch, and the alarm bell of one deck sounds, if one deck nobody hear, just can't know whether elevator breaks down to close the people; When sometimes power fail appears in elevator, because the car of elevator passenger loading all is that metal foil is made, produce signal shielding, mobile phone can't with extraneous communication, like this, it is of common occurrence to cause time of fail close people to surpass several hours accident, even violence occurs drives ladder, and then causes larger safety misadventure.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of elevator malfunction rescue alarm device is provided, and can realize remote alarms, avoids the oppressive time oversize, causes larger potential safety hazard.
Its technical scheme is: at the alarm button place of elevator electrical connection fault warning processing unit, the power supply of fault alarm processing unit connects civil power by ups power, the mouth of fault alarm processing unit is connected with the communication of Control Room client by the network sending module, and described fault alarm processing unit adopts 89S51 series monolithic and MAX485 communication module.
The input end of 89S51 series monolithic is connected to the alarm button of elevator by photoelectrical coupler, resistance, and the mouth of 89S51 series monolithic is connected with the MAX485 communication module.
The beneficial effects of the utility model are: when elevator faults occurring, it is client that the occupant just can directly send to long-range monitoring by alarm button with stranded information, thereby timely trouble-shooting avoids occuring larger safety misadventure.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is interconnecting wiring diagraies of fault alarm processing unit of the present utility model.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
Its technical scheme is: at the alarm button SW place electrical connection fault warning processing unit of elevator, the power supply of fault alarm processing unit connects civil power by ups power, avoid elevator power failure to cause warning also can't use, the mouth of fault alarm processing unit is connected with the communication of Control Room client by the network sending module, described fault alarm processing unit adopts 89S51 series monolithic and MAX485 communication module, physical circuit connects: SW connects signal connecting line at alarm button, pass through resistance R, photoelectrical coupler OC is connected to micro controller system 89S51, and the mouth of micro controller system is connected with the MAX485 communication module.
When elevator faults occurring, it is client that the occupant just can directly send to long-range monitoring by alarm button with stranded information, thereby timely trouble-shooting is avoided occuring violence and driven ladder, and then may cause larger safety misadventure.
