I. Systematic Introduction

North PeakBF-8100 SDCIntelligent DigitalIPThe interconnected system is supported by large area network.VHF、UHFBand, supportDMRStandard and downward compatible analog format, all digital4FSKModem TechnologyTDMADual-slot technology makes full use of spectrum resources to improve user capacity. System-wideIPArchitecture, through cable public network, cable private network,4GPublic Network, Cable LAN, Wireless LANIPInterconnection ensures cross-regional and wide-area coverage.

System Platform Architecture

Based on advancedDMRDigital wireless communication technology, with the system data exchange control server as the core, uses computer technology to assist the comprehensive application of various data information input, storage, collection, analysis and display. System adoptionB/SThe architecture is composed of access layer, network layer and application layer. It includes system data exchange control server, base station, data transmission network, terminal, client, information collection point and other equipment. It achieves rich daily management and emergency management functions through scheduling management software.

DMRAdvantages of Digital Communication Protocol

Excellent Audioperformance

The application of narrowband codec and digital error correction technology has better noise suppression function and wider effective coverage.

Double user capacity

Double time slotTDMATechnology can be divided into2individual6.25kHzEqual width alternating slot, support2Group synchronous or independent calls.

Intelligent System Design

Personalized customization: customization of networking scheme of personalized system for customers

Fault self-check function: automatic reset of equipment failure to enhance system reliability

High Channel Utilization Rate: Intelligent design is adopted in the system, which has higher channel utilization rate and saves investment and operation cost.

Easy maintenance: compatible with different frequency bands, various voice communications and data access interconnection, communication is more convenient

Digital Intelligent Management Platform

Real-time on-line monitoring: realizing efficient interaction and accurate and effective command and dispatch capability

Multichannel data and information transmission: ensure the real-time dispatch and communication between command center and officers;

Real-time digital voice: voice monitoring and alarm voice monitoring, to ensure that the command center to understand the scene;

Central network dispatching: the center can select single call, group call and full call dispatching commands to achieve rapid and accurate command and dispatching for processing;

Emergency alarm: Lock the real-time location of the alarm personnel quickly and inform the nearby personnel to give assistance immediately and accurately.

Three.System characteristics

• Command dispatch: dispatch, voice call (single call, group call, full call, etc.) can be realized by client and command seat dispatch desk.
• Text Information and Location/move/Voice monitoring, Electronics/Sentry fence, remote/Teleclosure and alarm settings/Data functions such as removing, switching channels, setting virtual inspection points, etc.
• Satellite positioning: based onGISData and terminal satellite positioning function, the system can display terminal location information in real time.
• Online patrol: hand-held terminal real-time card, patrol dynamic real-time background statistics, personnel patrol route real-time query, staff electronic fence settings.
• Telephone Gateway: Public Transfer Networks can be interoperable. Black-and-white list settings, short number mapping, predefined telephone directory, intercom terminals and public network phones can be dialed each other.
• Authentication function: The system has authentication function, only legitimate users can communicate after registration.
• IntelligenceIPInterconnection: Intelligent Implementation Based on Terminal Registration Information in the SystemIPInterconnection, intra-station communication only starts local relay, cross-station single call only starts two stations relay, cross-station group call only starts station relay with the terminal of the group call.
• Data management: Based on the system, it has abundant data management functions, supporting data entry and management of units, positions, users, equipment, terminals, patrols, etc.
• Real-time massive historical data query: support historical data query such as alarm, patrol, recording, shift, positioning trajectory, scheduling, switch, equipment on-off, sending short messages, etc.
• Convenient and intelligent equipment management: terminal status monitoring, relay remote frequency writing and terminal web page frequency writing can be realized in the air through dispatching background.
• Integrated management of multi-terminal: related data can be used in mobile phonesAPPFlat panel,PCEnd-to-end comprehensive view.
