With the increasing strength of China's comprehensive national strength, large-scale conference activities are becoming more and more frequent, and it is a huge challenge for the public security communication network during the conference。How to create a set of "all-round, visual, multi-level" PDT digital cluster security system in the case of limited police force, to ensure that the conference can be held safely, stable and reliable important communication guarantee, which has become the top priority of current communication。
What are the main difficulties in security communication for large conferences
(1) There are many police types and officers involved, and even a large number of police forces need to be dispatched from other places to support security work;
(2) The communication systems of relevant public security organs, emergency support, traffic management, medical assistance and other departments are different;
③ Different work levels have more tasks, frequent calls, and large call traffic;
(4) The command center did not communicate with front-line police personnel in a timely manner and could not accurately grasp the situation on the scene。
System advantage
Based on the above difficulties, Beifeng made full use of a number of independent intellectual property patent technologies to build a set of "all-round, visual, multi-level" multimedia communication integration management and control system。
Beifeng PDT digital cluster security system with integrated access, interworking, multi-level networking system platform features,It integrates multiple information means such as PDT digital cluster, video, voice scheduling, GIS and data service integration management,It realizes cross-system, cross-system, cross-region, cross-department and cross-operator interconnection,It truly meets the typical demand characteristics of "vertical scheduling, horizontal collaboration, unified command, and close cooperation" for large-scale conference security。
solution
① Multimedia fusion terminal to achieve visual scheduling
In addition to basic voice and data calls, the scheduling subsystem also supports diversified scheduling services such as voice conferencing, plan management, video surveillance, video conferencing, and system recording query。Through the SCP970 integrated intelligent handheld terminal, the audio, image and video information of the scene is transmitted to each command level in real time, so as to ensure that the conference security headquarters at all levels carry out flat command, point-to-point scheduling, and visual management on the scene, and realize the synchronization and symmetry of information between the front-line police force and the command center。
② All-IP network architecture, multi-department collaboration support
Public security organs, fire emergency, traffic management, medical assistance and other departments involved in large-scale conference security usually have their own communication networks and communication equipment. In large-scale event security, the command center needs to uniformly command the resources and personnel of various departments and various police forces。Beifeng PDT digital cluster security system is equipped with a multi-level core network, base stations and core networks, lower-level core networks and higher-level core networks are connected through IP networks, forming a unified command and communication network, to achieve multi-region, multi-base station, multi-department collaborative operations, and jointly complete the guarantee task。
③GIS information platform, emergency timely tracking
GIS information platform can position and track the mobile station by GPS query, so that the command center can dynamically grasp the deployment of police resources and police forces of various departments and police types。Once an emergency occurs at the meeting, it can be quickly adjusted according to the deployment of police forces, and the police can be mobilized nearby to deal with various emergencies。
④ A strong integrated management platform to build a unified command network
Beifeng PDT digital trunking security system is interconnected with other trunking systems, conventional wireless systems and PSTN systems through converged communication gateway,Realize multi-system integrated scheduling,Unified voice and data scheduling,To achieve the purpose of multi-communication means integration, multi-network integration, multi-service comprehensive guarantee。In the security of large conferences, the integration of various networks is realized to form a unified communication command network。
Application value
The traditional narrowband system is limited by the standard bandwidth, and can only provide limited data capability, which limits the development of its informatization。Beifeng PDT digital cluster security system in addition to the continuation of conventional PDT, DMR wireless communication business,It also meets the requirements of video surveillance, remote data acquisition, multimedia broadcasting and other data services,In the process of command and dispatch,Fully meet the needs of practical application scenarios such as integrated voice scheduling and visual command for large-scale event security,Enhance the efficiency of police work。
