From May 13 to 15, the 3rd Yangtze River Delta International Emergency Disaster Reduction and Rescue Expo was held at the National Convention and Exhibition Center (Shanghai)。With the theme of "Promoting high-level safety and escorting high-quality development", the expo attracted more than 500 representative units in the field of emergency response across the country。

　　As a leading provider of emergency communication solutions in China, Beifeng Communication brought professional cluster communication solutions, integrated emergency communication solutions of heaven and earth and a number of explosion-proof/public-private integration terminal products to the public, and comprehensively demonstrated innovative solutions and the latest technological achievements in multiple scenarios。

　　With the increasing complexity of emergency rescue scenarios, the traditional single voice communication solution has been unable to meet the communication needs of emergency times, and emergency communication services are rapidly changing to information, intelligent, and visual services to provide more efficient services。对此，Beifeng Communication at the exhibition site for all aspects from emergency rescue to disaster communication，It focuses on providing communication support for the command and dispatch of governments at all levels, providing communication and liaison for various rescue teams, and providing public communication services such as voice/short message for people in disaster areas，Improve emergency rescue response capability in all aspects and multiple scenarios。

　　Professional cluster communication network · Multi-level visual scheduling

　　The professional cluster communication system designed by Beifeng for all levels of government command and dispatch, daily service, fire and first aid and other emergency tasks is a multimedia communication integration control system integrating PDT/DMR cluster, video, monitoring, text, voice scheduling and other functions。Based on the communication features of critical tasks and critical services, the system meets the requirements of data services such as video surveillance, remote data acquisition, and multimedia broadcasting. In the process of command and dispatch, the system has the characteristics of "audible" and "visible"。With comprehensive access, interworking, multi-level networking system platform characteristics，To achieve cross-system integration, front and rear through the visual command and dispatch capabilities，It makes up for the gap that traditional narrowband communication cannot transmit pictures, videos and big data，It realizes cross-system, cross-system, cross-region, cross-department and cross-operator interconnection，It provides key cooperative communication guarantee for maintaining social security, establishing task network and responding to emergencies。

　　Integrated emergency communication between space and Earth · Flexible deployment and efficient response

　　With the industry's most advanced narrowband, broadband wireless communication technology, products and solutions，Beifeng Tiandi Integrated emergency converged communication solution uses portable devices with highly integrated design，It can be in the extreme three-break conditions of "off the network, off the circuit, off the power"，Fast rollout without any infrastructure，An emergency communication network covering a wide range of areas should be established in the first place。It makes full use of satellite, 4G, shortwave, ultrashort wave and other "heaven, earth and space" multi-network fusion communication means，Provide voice, image, fax, data, HD video and other diversified application requirements for emergency rescue sites such as emergencies, natural disasters, urban and forest fire，To realize the emergency rescue unit to the accident and disaster situation of the full control，We will comprehensively raise the level of information technology in emergency operations。

　　Especially in the face of natural disasters such as earthquakes, floods, mudslides, ice and snow, the communication network in the disaster area is often damaged to varying degrees, and the outside large-scale equipment cannot quickly enter the scene。The AD hoc emergency voice communication blindcomplement scheme built by BF-TR925 AD hoc network equipment can effectively solve the communication coverage problem of on-site rescue。In the extreme harsh environment that neither public nor private networks can cover，The BF-TR925 AD hoc network equipment can quickly and flexibly build communication networks, fixed and mobile wireless communication private networks at the disaster site，Establish chain, tree, star and network emergency communication network，Thus effectively solve the problem of communication link between the command site and the rear command center，Guarantee "100% coverage" in the last kilometer of rescue。

　　Public fusion/explosion-proof terminal · Fusion configuration collaborative operation

　　Beifeng is well aware of the emergency industry users' demand for safe and reliable communication equipment, and this exhibition also exhibited a number of "fist" terminal products。At the scene, under the guidance of Beifeng technical team, many exhibitors actually operated and understood the latest generation of BP series narrowband walkie-talkie, public network walkie-talkie, intelligent fusion walkie-talkie, explosion-proof walkie-talkie and other equipment, and intuitively understood Beifeng's professional strength and actual combat effect in the field of emergency communication。

　　As a private network communication enterprise that continues to deeply cultivate the field of emergency communication, Beifeng Communication has been committed to providing customers with end-to-end, customized professional solutions for more than 30 years。In the future, Beifeng will continue to iterate and enrich emergency communication solutions and products, continue to optimize its own technological innovation and service level, and contribute to the construction of an efficient and safe emergency communication network system。
