Embodiment 1

[0069] The following is a detailed description of the remote intercom system that sends the sound signal a to the internal staff of the control station A in conjunction with the road bureau.

[0070] as attached Figure 4 As shown, the railway bureau needs to send a sound signal a to the internal staff of the control station A. First, the railway bureau needs a voice input device, specifically a microphone, to input the sound signal a through the microphone.

[0071] The input voice signal a is recorded on the client side of the road bureau, and at the same time, the voice signal a is converted from the voice signal a to the digital signal b through the client, and the converted digital signal b is based on the remote intercom service The address of the terminal is used for network data transmission, and the transmitted data b is converted from digital signal b to sound signal a at the server end, and information transmission and conversion are completed here.

[0072] After ...

Embodiment 2

[0074] The following is a detailed description of the process of sending the voice signal c to the railway bureau by the staff in the control station A to implement the remote intercom system.

[0075] as attached Figure 5 As shown, the staff in the control station A input the voice signal c through the walkie-talkie, the voice signal c is converted into a digital signal d at the server end, and the digital signal is transmitted through the network according to the client address. The terminal restores the digital signal d to the voice signal c, records and stores the converted voice signal c, and sends it to the voice playback device.

[0076] The intercom process is completed through the sound external device, specifically to play the sound through the loudspeaker.

[0077] Therefore, the beneficial effects of the embodiments of the present invention are:

[0078] 1. The system design for instant voice communication from the railway bureau to the control station, and the ...

Abstract

Provided are a long-distance intercom system and method in a railway administration and a control station. The long-distance intercom system in the railway administration and the control station is characterized in that a railway administration platform and a control station platform are included, wherein the railway administration platform comprises a voice input device and a client side, the control station platform comprises a service side and an intercom system, the voice input device is used for receiving sound signals of railway administration working personnel and sending the sound signals to the client side, the client side is used for receiving the sound signals, carrying out recording and storing and converting the sound signals to digital signals, digital signal network transmission is carried out according to the address of the service side, the service side is used for receiving the digital signals, then converting the digital signals to sound signals and sending the sound signals to the intercom system, and the intercom system is used for playing the received sound signals. Real-time voice communication in the railway administration and the control station can be achieved, and meanwhile voice communication is achieved through long-distance intercom, and a large amount of telephone communication cost is saved.

Description

technical field [0001] The invention relates to the field of system design, in particular to a remote intercom system and method in road bureaus and control stations. Background technique [0002] At present, with the rapid development of railway informatization, more and more centralized management and control models are adopted by railway bureaus. At the same time, railway passenger lines and passenger flow density are increasing linearly, and the operation of railway transportation is facing unprecedented challenges. As an important place for the interface between railways and passengers, passenger stations are widely distributed and cover a large area, which brings difficulties to the centralized management and control of railway bureaus. The real-time intercom communication and real-time voice communication between the railway bureau and the personnel in the station have become an important way for the railway bureau to deal with sudden emergencies at the station, and i...
