Wireless communication system for large-scale sports events

Project background

Beijing 2022 The 2008 Winter Olympic Games officially came to an end , Olympic athletes from all countries have dreams on the field 、 Passion burning , Leave a wonderful moment for Olympic Sports . As an international sports event , It's important to keep communication open , intelligent IP How does the interconnection system play its key role in the emergency communication of large-scale events ?

Demand analysis

In large-scale events , It is very important to ensure smooth communication on the field , Due to the mobility characteristics of managers , Using radio communication to ensure that relevant personnel of the event can communicate effectively anytime and anywhere is a necessary means to ensure the orderly progress of the event . Large sports venues are numerous and scattered , Bring challenges to unified management ; The complex building structure of each gymnasium project and the influence of electronic equipment , As a result, the wireless interphone signal cannot reach all areas in the project .

The construction of wireless intercom system is very important for security 、 engineering 、 The management work of cleaning and other departments will bring great convenience , Can achieve high efficiency 、 Deal with all kinds of emergencies in real time , Minimize possible losses . Especially when an emergency occurs , A set of wireless intercom system covering the whole project , Click to connect 、 a hundred responses to a hundreds , Be able to quickly organize and dispatch personnel , Escape 、 Rescue 、 Rescue and other work , Effectively implement the emergency plan .

Solution

In order to meet the communication needs of various large-scale sports events , Beifeng communication design BF-8100 SDC intelligent IP Interconnected systems , The system is positioned as an industry application-oriented system product between conventional voice communication and cluster command and dispatching system , It can realize higher-level intelligent dispatching management , Meet the command, dispatching and management needs of large-scale sports events ：

l Multiple competition venues distributed in different regions realize their own wireless signal coverage .

l Independent communication between venues .

l The command center can communicate with multiple competition venues in different regions .

l The staff in each venue need to carry out packet communication at the same time .

l Single or group scheduling can be carried out for the staff of each competition venue .

System advantage

BF-8100 SDC intelligent IP The interconnected system is based on advanced technology DMR Digital wireless communication technology , Take the system data exchange control server as the core , Computer technology is used to assist the input of various data information 、 Store 、 collect 、 Comprehensive application of information analyzed and displayed , Meet the needs of basic voice communication and realize intelligent management and scheduling at the same time . The system adopts large area system networking mode , Support VHF、UHF Frequency band , Meet the needs of large-scale networking ; The whole system is adopted IP framework , Through wired public network 、 Wired private network 、4G Public network 、 Wired LAN 、 Wireless local area network IP interconnection , Ensure cross regional and wide area coverage .

intelligence IP interconnection

With 2022 Take the 2008 Winter Olympics as an example , In addition to the large number of participants from various countries , Live audience 、 There are countless media personnel . System USES B/S Architecture and full IP Chemical technology , Realize intelligence IP interconnection . In station communication of different departments, only local relay can be started , Cross station single call only starts the relay of two stations , The inter station group call only starts the site relay with the terminal to which the group call belongs , So as to ensure real-time 、 accuracy 、 Effective intelligent management ability , Improve the management efficiency of units and personnel .

Remote command and dispatching

Due to limited coverage , The mobile communication between athletes and staff in different venues is very important . In order to ensure emergency communication within a limited range around the venue , The system will set up large relay equipment in different venues , Use the intelligent channel sharing system as the exclusive emergency channel inside the venue . The terminal is equipped with emergency alarm 、GPS location 、 Patrol clock and other functions , Further ensure the on-site security and event command and dispatching . In case of emergency , The command center personnel can initiate the group call with one click , Quickly arrange nearby personnel , Meet the needs of cluster communication and scheduling of large-scale events .

Fully integrated communication gateway

When there is an event in the stadium , The referee on the court 、 Volunteers and the security team responsible for the smooth progress of the event and the safety of the audience , There is great liquidity 、 The working position is not fixed . Especially in densely populated areas , Abnormal congestion of operators' networks often occurs on site , Unable to get communication in time .

The system integration gateway is used to ensure cross system security 、 Cross network unified command and dispatching communication . In a noisy environment , Private network communication technology can be used for stadium operators 、 The team 、 Provide security for the audience , So that the team staff can be anywhere in the stadium at any time 、 Communicate at any time , So as to improve the efficiency of team cooperation , Fast response to demand , Coordinate resources accordingly . It not only ensures the key communication channels in the venue , It can also connect all relevant personnel , Achieve the best of both coverage and no communication dead corner , Ensure the smooth progress of major international events !
