Abstract
The invention provides a 2.4 G wireless communication based elevator emergency alarm and intercom device and relates to the technical field of elevators. The 2.4 G wireless communication based elevator emergency alarm and intercom device comprises an internal machine and an external machine which is in communication connection with the internal machine; the internal machine is formed by a 2.4 G wireless communication module and an input and output matching circuit; the external machine is formed by a 2.4 G wireless communication module and an audio input and output channel display circuit. According to the internal machine, the seamless connection between the 2.4 G wireless communication based elevator emergency alarm and intercom device and a general type elevator emergency alarm and intercom device is achieved through the input and output matching circuit, the state of an external circuit is judged and the calling, off-hook, intercom and on-hook of the wireless communication module are controlled by a single-chip microcomputer which is arranged in the 2.4 G wireless communication module, and accordingly the wireless intercom call between an elevator lift car and the elevator management personnel or maintenance personnel can be achieved. According to the external machine, the calling of six different internal machines can be received, the number of the calling internal machine can be displayed, and the wireless call can be achieved.
Description
Technical field
The present invention relates to elevator technology field, be specifically related to a kind of elevator emergency warning talkback unit based on 2.4G wireless telecommunications.
Background technology
In general, elevator is the longitudinal transport mechanism for moving up and down in building, plays the effect of the social infrastructure of many people's utilizations.Therefore, in elevator, possess for guaranteeing the various structures of client's safety.In elevator use procedure, for avoiding personnel stranded because of elevator faults, require to install emergency alarm device in lift car.This device is generally tripartite or five side's intercom systems of four-wire system, need to watch house, lay a quad by elevator, along with the scale of the present residential district community is increasing, the distance of its wiring is more and more far away, quantity is more and more, makes troubles to the installation and maintenance of elevator.The wireless telecommunications that 2.4G radio-type elevator emergency warning talkback unit utilizes 2.4GHz frequency range, realize the intercommunication of elevator wireless emergency alarm.
Summary of the invention
