Solution of Station Public Address System


(Bus Station, High-speed Railway, Subway, Railway Station) Public Address System-Scheme Construction


System Overview
The digital IP network broadcasting system adopts the TCP/IP network technology widely used in the world today, and transmits the audio signal in the form of data packets on the local area network and wide area network, which completely solves the problems of poor sound quality, complex maintenance and management, and poor interactive performance of the traditional broadcasting system. The system equipment is simple to use, easy to install and expand, just connect the digital broadcasting terminal to the computer network to form a powerful digital broadcasting system.


demand analysis
Requirement 1: The power supply of the broadcasting system is unified and cannot be controlled by the total power switch of each platform;
Requirement 2: Set up sub-control room according to actual requirements;
Requirement 3: The station can be organized at will for different platform areas to facilitate partition management;
Requirement 4: The broadcasting system software can use Pinyin input method and five-stroke input method to input text for editing instructions;
Requirement 5: Save a certain number of broadcast system instruction templates, and some broadcast system instruction templates can be automatically switched to execute according to the set time;
Demand six: mobile phone or computer can remotely control the broadcast system software, edit and modify the instructions;
Demand seven: in the patrol broadcast, such as the station can call through the broadcast system to remind, in order to deal with emergencies in a timely manner.
Demand eight: linkage with the station fire system, in case of fire or other emergency, so that the station staff can take timely measures;

 

Design Ideas
Implementation 1: Separate power supply to the broadcast speakers in important areas of the station platform, IP addressing speakers, power amplifiers, switches and other equipment in the network broadcast part, which are all led from the host room to each platform and are not controlled by the power switch on the floor where each platform is located;
Implementation two: according to the actual needs to set up sub-control room, each broadcasting station is equipped with sub-control computer, network paging intercom microphone, mixer and network audio encoder;
Implementation 3: IP network broadcast addressing wall-mounted sound box auxiliary box is adopted in the station platform area, which can not only realize independent control, but also carry out unified broadcast and regional broadcast to flexibly meet actual needs; Each station and public area adopts IP network decoding terminal power amplifier sound box, and public area plays different broadcasts at the same time in different areas according to needs;
To achieve four: broadcast system software supports Pinyin input method and five input method, and can be switched at will;
Implementation 5: There are 1000 broadcast system instruction templates that support saving. Multiple broadcast system instruction templates can realize timing switching function, and instruction templates can be copied;
Implementation 6: The broadcast system sub-control software/mobile phone software can run on any computer/mobile phone on the broadcast network, providing a remote operation platform for broadcast administrators and users of the broadcast system;
Implementation 7: The CD player power amplifier IP network broadcast addressing wall-mounted sound box constant pressure backup module is used to realize that when single or multiple devices in different areas are out of network or power failure, the analog backup system replaces the IP broadcast system for non-delay broadcasting. At the same time, if the main power amplifier fails, the main-standby switch will switch to the standby power amplifier immediately when it detects abnormal signal, and continue to remind the call;
Implementation 8: Configure IP network alarm host, which can connect with the hospital's own fire fighting system. When the fire fighting system receives an emergency signal, it will instantly activate the IP network alarm host. The network alarm host will alarm in zones, regions and temporary floors according to corresponding settings, and cooperate with linkage output to trigger other equipment to carry out emergency actions.

 

Functional advantages
(1) graphical interface, easy to learn; touch screen operation, easy to use.
(2) Mobile phone APP remote control playback function: supports uploading files to the server, instantly playing the internal audio files of the mobile phone, and can be broadcast at any time through the paging function.
(3) Text broadcasting function, the system can directly convert text into audio files, and install the corresponding voice package to customize the sound on demand.
(4) File playback function, centralized control room and each sub-control area can be played through software selection files.
(5) Real-time acquisition and broadcasting function, real-time acquisition of traffic information release, ride guidance, safety warning, emergency broadcasting, entertainment and knowledge dissemination, staff broadcasting and command and dispatch, etc;

 

Application effect of daily station public broadcasting:
Provide real-time train information: the station broadcasting system can update the arrival time, departure time and delay of the train in time, providing accurate train information for passengers, so as to facilitate them to arrange the journey and waiting time reasonably.
Transfer guidance and traffic scheduling: The broadcast system can provide passengers with transfer guidance and traffic scheduling information. When a line fails or is adjusted, the broadcasting system can notify passengers in time and provide alternative transportation plans to help passengers plan their journey.
Safety warning: The station broadcasting system can also be used to issue safety warnings and reminders to remind passengers to comply with the regulations and pay attention to safety. For example, passengers are required not to approach the edge of the platform, not to stand while the vehicle is driving, etc., in order to improve the safety awareness and behavior of passengers.
Public service notification: The broadcasting system can also be used to issue public service notifications, such as shop activities around the station, tourist information, community announcements, etc. Such applications can provide passengers with practical information and provide better service and shopping experience.
Emergency notification in case of emergency: In case of emergency, the station broadcasting system can quickly issue an emergency notification to inform passengers to take necessary safety measures. For example, in the event of a fire, bad weather, or other emergency, the broadcast system can communicate evacuation instructions and safety reminders to passengers in a timely manner.
