The three-day 2024 Guangzhou International Emergency Safety Expo concluded successfully at the Guangzhou Canton Fair Exhibition Hall from June 16th to 18th! As one of the invited exhibitors, Beifeng Communication showcased its innovative solutions and core technology products in the emergency industry, including 370MHz PDT digital cluster solutions, wide/narrow self-organizing network on-site emergency communication solutions, multi network fusion visual emergency command and dispatch solutions, as well as a new series of wide and narrow fusion terminals, explosion-proof walkie talkies, digital walkie talkies, PoC walkie talkies, and other multi standard communication equipment. It attracted numerous emergency rescue departments and industry partners to visit, exchange and interact.

In response to multidimensional applications in different emergency communication scenarios, Beifeng Communication adopts a multidimensional networking approach of "complementary public and private networks, combined fixed and mobile networks, and integrated wide and narrow networks", providing a series of emergency wireless communication solutions covering the rear command center, front command center, and rescue site, including emergency narrowband wireless communication network, public and private fusion network, portable emergency communication network, etc., to achieve cross system integration and visual command and dispatch capabilities that connect the front and rear, and jointly promote the diversified development of the emergency safety industry.

370MHz PDT digital cluster system

The Beifeng 370MHz emergency narrowband communication network, as one of the key means of emergency voice communication, enhances the emergency communication and command capabilities of cities and towns through different deployment methods such as mobile vehicle mounted, distributed, and fixed base stations. It highlights the solution to the emergency communication needs of on-site communication coverage and response to natural disasters, including "fixed mobile combination, hierarchical coordination, front and rear connectivity, and unified command".

The 370MHz emergency narrowband wireless communication solution, based on the communication characteristics of system critical tasks and critical businesses, leverages the advantages of regional networking, multi-level encryption, diverse network management capabilities, and advanced platform architecture to achieve cross standard, cross system, cross regional, cross departmental, and cross operator interconnection during command and dispatch.

Wide/narrow self-organizing network on-site emergency communication system

The wide/narrow self-organizing network on-site emergency communication system developed by Beifeng can independently complete the rapid deployment of wireless communication networks in complex scenarios without relying on external networks, and provide timely and efficient key voice communication support for on-site emergency rescue teams in the event of "three disconnections" (circuit breakers, power outages, and network disconnections) to meet the needs of quick recovery and emergency support.

The Beifeng wide/narrow self-organizing network on-site emergency communication system adopts a new "wireless mesh network" concept design, with a distributed network architecture without a central self-organizing network, ensuring that all nodes can achieve real-time interaction of multiple media information such as voice, data, and images under non line of sight and random fast movement conditions.

The BF-TR925 self-organizing network equipment construction self-organizing network emergency voice communication blind filling solution can effectively solve the "last mile" communication link problem between the command site and the rear command center when facing situations such as congestion and blockage of public network communication networks, damage to base stations caused by fires and earthquakes, lack of signal coverage in remote areas, and execution of special tasks, and improve the command decision-making and collaborative rescue efficiency of emergency rescue communication.

Multi network fusion visualization emergency command and dispatch system

The multi network fusion visual emergency command and dispatch system independently developed by Beifeng combines satellite, unmanned aerial vehicle, ground communication and other means to form a three-dimensional communication network between heaven, earth and air, meeting the emergency communication needs of users under various conditions. It can operate independently in an isolated island environment, and the narrowband private network provides voice and narrowband data services; Deploy a fusion communication platform in the rear command center, utilizing broadband networks/satellite links to provide video communication and public network services, thereby breaking down communication barriers between multiple departments and providing a "windward ear and a thousand mile eye" for command centers at all levels to obtain frontline information.

The multi network fusion visual emergency command and dispatch system brings emergency communication solutions and rich terminal applications from the platform to the terminal. The new series of narrowband walkie talkies, public network walkie talkies, intelligent fusion walkie talkies, explosion-proof walkie talkies and other equipment exhibited this time ensure the integration and interoperability of various types of audio and video and island communication systems in emergency sites, effectively improving the flatness, visualization and practical level of emergency communication command.

At this exhibition, Beifeng Communication fully demonstrated the multidimensional integration of products and information technology in emergency rescue work. In the future, Beifeng Communication will continue to deepen its expertise in emergency rescue and safety communication, continuously strengthen its research and development innovation capabilities, closely integrate various emergency scenarios and market demands, continuously iterate and enrich emergency products and solutions, promote the in-depth development of innovative technologies in the emergency industry, and work together with customers and partners to build a new emergency blueprint.
