Elevator emergency call communication system and method

Abstract

The invention discloses an elevator emergency call communication system and method. The system comprises a call terminal and a communication switching module, wherein the communication switching module is in communicating connection with a far-end server through a network communication or GSM communication mode; the far-end server is connected with a communication terminal; the communication switching module receives voice signals, compresses the voice signals according to a predetermined algorithm, detects a network time-delay state of the far-end server, if a time delay is within a threshold scope, sends the voice signals to the far-end server through the network communication mode, and otherwise, sends the voice signals through the GSM communication mode; and the far-end server detects the communication state of the communication terminal, if a detection result is suitable for communication, sends decompressed voice signals to the communication terminal, and otherwise, switches the communication terminal until connection is established. According to the invention, through arrangement of at least two communication modes, a communication module can be switched according to the time-delay state of network communication, the communication quality is ensured, elevator accident rescue untimeliness caused by communication delays is avoided, and the reliability is high.

Description

technical field [0001] The present invention relates to the technical field of elevator communication, more specifically, it relates to an elevator emergency call communication system and method. Background technique [0002] The elevator intercom is a communication device installed in the elevator car. When the elevator encounters an emergency, the personnel in the elevator car can use the above-mentioned equipment to get in touch with the outside world. [0003] As far as the current elevator communication equipment is concerned, there are still some problems, for example: due to the serious signal shielding in the elevator shaft, it is difficult to use general wireless intercom equipment to get in touch with the outside world; secondly, because the current intercom equipment is one-to-one It is set, that is, when the calling end initiates a request, if there is no response from the receiving end, the request will be considered invalid, or the request cannot be answered wi...

Problems solved by technology

[0003] As far as the current elevator communication equipment is concerned, there are still some problems, for example: due to the severe signal shielding in the elevator shaft, it is difficult to use general wireless intercom equipment to get in touch with the outside world; secondly, because the current intercom equipment is one-to-one It is set, that is, when the calling end initiates a request, if there is no response from the receiving end, the request will be considered invalid, or the request cannot be answered within the valid time. Based on the above two reasons, it is required that the communication can be effectively established, and Ensure that the elevator intercom system has good real-time performance and continuity of voice communication
