Urban emergency management - urban emergency communication command and dispatching system

　　 With the rapid development of China's urban gas industry 、 The continuous expansion of gas supply range , As a result, residents' demand for gas is increasing . however , in recent years , Urban gas explosion accidents occur frequently , It has brought great harm to people's life, health and property safety .

　　 Accident background

　　10 month 21 Japan 8 when 20 branch , Taiyuan South Street, Heping District, Shenyang City 222 There was an explosion on the th , The explosion impact caused damage to nearby buildings , A bus at the scene was affected . at present , The accident has caused 3 People have been killed ,30 Others were injured , All the wounded have been sent to hospital for treatment , Accident investigation and follow-up rescue work are in progress .

　　

　　 Accident characteristics

　　(1) universality

　　 Natural gas 、 Gas is supplied by pipeline , Liquefied petroleum gas is mainly in the form of tank . Urban gas pipelines and facilities are arranged in a wide range , Accidents can happen anywhere there are gas pipelines or facilities .

　　(2) Burstiness

　　 Gas accidents in alkali cities are often caused by the damage of equipment and pipelines , It usually happens without warning , With sudden .

　　(3) Unpredictability

　　 Urban gas accidents generally have nothing to do with climate and other reasons , Any season 、 It can happen in any weather condition .

　　(4) It's a big influence

　　 Once a gas accident occurs , The scope of influence is relatively large , Not only affect production 、 Transportation 、 Place of use , Certain areas around will be affected by the accident . Such as in residential buildings , A gas explosion occurred in a house , It may affect the whole building .

　　(5) Cause secondary disasters

　　 The gas accident itself can form the main disaster , The earthquake is 、 A landslide 、 Stratigraphic changes 、 In case of flood , The destruction of gas facilities will cause secondary damage .

　　 Solution

　　

　　 In view of the weak links of urban management emergency response , There is an urgent need for a set of measures to ensure on-site safety “ Communication is smooth 、 Information is timely 、 Complete data 、 Command in place 、 Easy to carry 、 Easy to deploy 、 The environment is adaptable ” And other omni-directional communication systems integrating heaven, earth and air .

　　BF-9000 Mission critical communication system receives reports of emergencies 、 Real time early warning, monitoring, prevention and control 、 Coordination and emergency management are the core , Adopt preset backbone network 、 On site emergency network 、 Three layer networking mode of unit combat network . Integrate multiple means of communication to ensure cross regional communication 、 Cross departmental information sharing and coordination command , Meet the requirements of urban emergency management department “ Comprehensive 、 Three dimensional 、 visualization ” Emergency management needs , Ensure that the command centers at all levels understand the on-site situation in real time , Provide effective communication support for urban emergency rescue .

　　 Application value

　　(1) Integrated sky, earth and air monitoring

　　 The scheme can be combined with satellite 、 Unmanned aerial vehicle (uav) 、 Ground communication forms a three-dimensional communication network of heaven, earth and air , Understand the situation of the accident scene in real time through diversified terminal equipment , Provide for urban emergency management “ One screen view ” At the same time , Meet the basic needs of communication scheduling at all levels , Achieve integrated “ God 、 empty 、 The earth 、 people ” Four dimensional interworking effect .

　　(2) Integrated information fusion

　　 Narrowband private network provides voice and narrowband data services , Broadband network provides video communication and data services . The construction of wide-band communication integration scheme 、 Distributed integrated information communication system with optimized structure , While ensuring the real-time command and dispatching of the front and rear sides , For each department 、 Hierarchical business construction is efficient 、 accuracy 、 A new mode of unobstructed emergency communication .

　　(3) Standardized military equipment

　　 All system base stations are made of military standard all cast aluminum fuselage , Heat dissipation is fast and durable . The portable design is convenient for urban sudden accidents in a short time 、 Withdraw 、 Transfer equipment , Adapt to the harsh environment of the accident site , The service life and application value of the equipment are prolonged .

　　(4) Flexible networking

　　 The system equipment can be used immediately after startup , It can work alone or networking , The subordinate relationship on the command network is clear . The advantage of one machine for two purposes , It can connect the superior with the command network at the same level to realize leapfrog command , Improve emergency reporting 、 Emergency command and dispatching management 、 Instant messaging and other work efficiency , With “ Flexibility + Instant ” Boost the realization of “1+1>2” To improve the efficiency of .

　　(5) Secure digital encryption

　　 The system adopts dynamic 、 Static voice encryption , Fundamentally solve the problem of information security , The circuit design adopts large-scale digital circuit, which is stable and reliable .
