IP conversion device of analogue intercom terminal in entrance guard intercom system

Abstract

The invention discloses an IP conversion device of an analogue intercom terminal in an entrance guard intercom system. The IP conversion device comprises a 485/232 interface module, an IP generating module, a network interface module, an audio processing module, a communication module and a processor, wherein the 485/232 interface module is used for analyzing the terminal information of the analogue intercom terminal, the IP generating module is used for obtaining corresponding IP address information through calculation according to the received terminal information, the network interface module is used for being connected with a mobile terminal in a communication network through the TCP/IP protocol, the processor is used for sending communication command information to the communication module after the IP generating module obtains the IP address information, the communication module is used for sending an audio data packet according to the mobile terminal corresponding to the communication command information and the IP address information or receiving an audio data packet from the mobile terminal, and the audio processing module is used for coding a local audio signal and then transmitting the coded audio signal to the communication module or decoding an audio data packet received by the communication module into an audio signal. By the adoption of the IP conversion device of the analogue intercom terminal in the entrance guard intercom system, IP networking of the analogue intercom system can be achieved.

Description

technical field [0001] The invention relates to the field of access control intercom technology, in particular to an IP conversion device for an analog intercom terminal in an access control intercom system. . Background technique [0002] At present, most of the access control intercom systems are analog intercom systems, and the analog intercom systems have the following status quo: [0003] 1. Adopt non-IP (Internet Protocol, the protocol for interconnection between networks) network intercom system, the wiring method is relatively complicated, audio lines and data lines are required, and many intermediate switching devices are required, and the signals are easily interfered and attenuated. [0004] 2. If there is a problem with the transmission audio and data signal lines, it is difficult to troubleshoot and rewire. [0005] 3. It is not compatible with the digital intercom system, and the superiority of the digital intercom system cannot be reflected in the analog int...
