It can hold intercontinental and national comprehensive sports games and international track and field and football competitions, with nearly 65,438+10,000 fixed audience seats. Functionally, volleyball, basketball, badminton, table tennis, handball and gymnastics competitions can be held, and large-scale conferences and mass song and dance performances can also be held, forming a new urban area with sports and Expo functions as the mainstay and integrating business, tourism, leisure, culture and residence functions.

The public broadcasting system of large-scale Olympic Sports Center is built for the daily humanized service and broadcasting function of the Olympic Sports Center, and it must meet the diversified functional requirements of the Olympic Sports Center, including daily background music broadcasting, background music broadcasting tasks in different regions, all-weather or scheduled time, and unattended; Broadcast of various real-time commercial broadcasts; The emergency intervention of fire-fighting broadcasting requires the broadcasting system to be efficient, stable, comprehensive, intelligent and diversified.

Two. Summary of CEO-PA Digital IP Network Broadcasting System in Baotou Olympic Sports Center

1, project overview:

The gymnasium of Baotou Olympic Sports Center has a building area of 20,379 square meters, three floors above ground and 5,954 seats. The whole projection plane is circular. 20 10 was completed in the first half of the year to prepare for the World Middle School Volleyball Championship held in Baotou. The central part is the competition venue, surrounded by athletes' lounge, equipment room, office and VIP room, press conference hall, press conference hall, audience and stage. The gymnasium of the Olympic Sports Center can be used for volleyball, basketball, badminton, table tennis, handball and gymnastics competitions, and can also hold large-scale meetings and mass song and dance performances. From the appearance, the shape of the Olympic Sports Center Gymnasium highlights the integrity of the building, and the combination of butterflies and spheres reflects the atmosphere of the times. Its shape also symbolizes time and speed, and its structure is like a timing pointer across the surface, which makes people vaguely see the footsteps of athletes chasing time and feel the spirit of hard work and enterprising. The construction of 26 new technologies, new materials and new processes in the museum makes the gymnasium more beautiful, environmentally friendly and three-dimensional, highlighting the atmosphere of Baotou's landmark buildings.

2, the system function requirements:

1): Play daily music in all-weather and time-limited zones, and some broadcast zones can be played with multiple audio sources.

2): It can broadcast and page any partition in the property monitoring room of the venue, and provide remote paging.

3): Fire-fighting linkage, with fire-fighting broadcasting function. The system needs software management and remote control functions.

4): The system equipment can be turned on regularly and play music regularly (the whole system can be controlled uniformly).

3. System scheme design:

According to its system requirements, CEO-PA network broadcasting system was adopted in the early stage. The system divides indoor and outdoor areas, and installs simulated lawn sound in the main gymnasium and outdoor lawn area of the gymnasium to play the background music and precautions of the stadium all day. Install suspended ceiling speakers in the gymnasium to play background music and daily business broadcasts, which are linked with the fire control system and forced by the fire control. The main control room is located in the weak current machine room in the main gymnasium, and the remote sub-control center is set in the property management center, so that the whole system can be controlled in real time without going to the main control room. A remote paging center is set up in the monitoring room, which is used for monitoring personnel to broadcast reminders in real time when they find abnormal conditions in the venue, so as to inform tourists to pay attention.

6. System function description:

1): There are many broadcast partitions, which are played regularly.

The system is divided into gymnasium, gymnasium periphery and parking lot, public fitness area and lawn area. Each district is partitioned independently, with independent control addresses and broadcasts. All-weather partition timing playback. For example, morning and evening convenience fitness broadcasts in public fitness areas. The public lawn leisure area plays background music all day, and the parking lot plays it regularly. Play has multiple playback modes; Built-in n schedules, multiple users can edit and change each schedule at the same time, and the timing control time is accurate to seconds, thus realizing remote control of playback. Unattended all day.

2): Multi-channel real-time sampling and broadcasting

It can collect and compress self-used radio, tape recorder, CD player, MP3 player, microphone and other programs in real time into high-quality data streams and store them in the server, and it can also be played to designated broadcasting terminals as required to play external equipment broadcasts and announcements. Can support the acquisition and playback of a single multi-channel sound card.

3): Online radio broadcasting

Internet network radio programs received by Internet radio software can be converted into IP network broadcast data format and broadcast to broadcast terminals in real time, such as some special language radio stations.

4): Radio program monitoring

The monitoring speakers are arranged in the basic sub-control center of the main computer room/sub-control room, which can monitor all broadcast programs in real time.

5): Alarm broadcast linkage

The alarm signal is input from the fire fighting system, and the intelligent linkage broadcast server processes and broadcasts the fire alarm.

6): Multi-channel partition broadcasting

The system can set any number of groups to play established audio programs or broadcast speeches to any designated area; The service software can remotely control the content (designated playing area) and volume of each terminal.

7): Terminal power control

The power supply system of each network broadcast terminal is controlled by the network broadcast control center, which automatically turns on its own power supply system and external control power supply function according to the broadcast signal, and the standby power is less than or equal to 0.3W.

8): Permission level setting

The software can be set up for multiple users to use system software or on-demand terminals, which are managed by the administrator in a unified way. The administrator assigns each user a system account and password, their access rights and the number of terminals. There are different levels, and the administrator has the highest authority. Only the administrator can set or change the setting parameters of the system.

9): Remote control function

The campus broadcast control room can realize remote control broadcast. So as to realize remote speech to the whole region, region and group through computer. Through the main server of IP network or any sub-control center (or computer equipped with sub-control software) on LAN, all, some or a single terminal can be designated to realize broadcast paging.

10): network remote paging and intercom function and recording and storage function.

The remote broadcast paging center can broadcast voice to any partition, or play music, or play the same music in combination with several partitions, or play it in any combination. Arbitrary grouping; You can speak to a certain area or a combination of several areas alone. Music plays normally in areas that have not been spoken. Broadcast voice can be automatically recorded and saved, and the main control center can monitor the real-time information of each terminal in the network at any time.
