I. Systematic Introduction
BF-9500 Police Digital Trunking Communication System (PDT) is a new generation of digital integrated products based on PDT standard. It can provide stable wireless communication and command debugging solutions for public safety, public utilities, industry and commerce.
The system has the function of automatically selecting information, realizing resource sharing, task sharing, channel equipment sharing, multi-purpose, efficient wireless dispatching and other communication services, and providing dedicated communication services for group users such as multiple departments and units.
II. Application Areas
BF-9500 police (PDT) digital trunking communication system is widely used in the daily command and dispatch work of public security departments such as public security, army, railway, aviation and so on. It provides a digital dispatch solution for remote dispatch and management.
III. System Advantages
Supporting the access verification of base station and terminal information, preventing illegal terminals with the same frequency information from occupying the channel, and ensuring the uniqueness of personnel information in the network.
The built-in multi-digital encryption technology supports ACR4, AES256 and soft encryption, full network link encryption and communication ciphertext encryption authenticated by the Ministry of Public Security. It can effectively avoid voice calls from scrambling and de-scrambling encryption channels and improve the security level of Intranet communication systems in all aspects.
Provide automatic replacement operation between main core network and standby core network, double routing link strategy and single station mode of operation, ensure that the system can run continuously when any link in the system fails, without affecting the normal voice service of subordinate terminals.
Using advanced digital technology, BSC (Base Station Controller) backup, application database backup, PMU (Power Supply) backup, control channel backup and link backup are realized, which facilitates users to access and view data information at any time.
When the terminal of the system is lost or the transceiver of a device is prohibited, telehalo/tele-death technology can be used to control the terminal equipment quickly, prevent the leakage of terminal information and ensure the privacy of communication.
When power failure occurs, the battery power supply mode can be activated or directly connected to the power supply for charging, providing a more flexible and convenient charging mode to ensure the normal operation of the system and improve the efficiency of user communication scheduling.
The whole equipment is compact in structure, which is convenient for installation, transportation and maintenance of daily communication dispatch. After a number of professional indicators verification and a variety of complex environment testing, it has excellent compression resistance and adaptability to meet the emergency communication needs of users in different scenarios.
It supports GPS/BD data flip channel, single channel can carry thousands of minutes / minutes to upload information, and provide precise and clear positioning information, so as to achieve true data transmission.
IV. Networking Mode
Provincial and Municipal Emergency Linkage Network
After the completion of the construction of district/county cluster system, it can access the city cascade network center and realize the interconnection and interoperability of the city system at the prefecture level; the city network center at the prefecture level is connected to the provincial network center to form the district (county), city and province three-level PDT/DMR network structure, and the provincial and municipal units can directly manage the county/district PDT cluster system. The PDT/DMR cluster of different units and departments can also be connected to the command center of prefecture-level cities in smart cities.
Introduction of System Composition
BF-9500 PDT Police System Base Station
BF-9500 Base Station adopts the modular design concept of cell, with high reliability and scalability, as well as powerful and rich business functions. Supporting multi-level fault weakening mode, the base station can handle calls independently in the station, effectively improving the reliability and efficiency of the product. The backup mechanism is used for key hardware components, such as base station controller backup, cluster master channel backup, network element link backup, etc.
BF-9500 system base station equipment uses two types of cabinets: four carrier frequency cabinet and eight carrier frequency cabinet. Four carrier frequency cabinet adopts 22U standard rack, eight carrier frequency cabinet adopts 37U standard rack. The design conforms to ETSI EN 300 113 standard, ETSI TS 102 361 standard, ETSI TS 102 362 standard and ETSITS 102 398 standard.

Support full duplex communication mode, so that intercom is no longer limited by traditional communication mode. Real-time synchronous feedback voice communicates in time at the critical moment of task execution, which makes command and scheduling more efficient and flexible, and effectively improves team work efficiency.
With the latest positioning chip, it can provide higher positioning accuracy and sensitivity, and support GPS/Beidou positioning service. It can easily realize real-time precise positioning and trajectory viewing, and facilitate timely personnel scheduling, emergency reinforcement and digital management.
Standard-based digital trunking communication technology, authentication, end-to-end encryption and other security technology applications, more so that you get a full range of security communications.
The 2-inch high resolution (320*240) IPS color semi-transparent and semi-reflective display screen greatly improves the viewing angle of users, and can display information at a glance even in strong outdoor light.
IP68 protection level, the fuselage anti-wear, high seismic strength, can play its excellent performance in a variety of harsh use environment, to avoid communication problems caused by environmental problems.
Provide capacity of 3350 mAh lithium-ion batteries, to meet the user's ultra-long call. Working hours in cluster mode can be up to 17 hours.
It adopts advanced narrowband speech coding and decoding technology, digital error correction technology and advanced AGC technology. Effective noise suppression, so that users can get clear voice. At the same time, the built-in 2W high-power loudspeaker ensures a clearer and louder voice, allowing users to easily maintain smooth communication.
