1、 Basic concepts of DMR narrowband fusion terminal
1.1 Introduction to DMR and Wide Narrow Band Fusion Technology
DMR stands for Digital Mobile Radio Professional Communication System, which is a mature and stable private network communication technology widely used in special industries such as public security, transportation, and energy.
The fusion technology of broadband and narrowband combines the stability of DMR private network communication with the broadband advantage of public network communication, achieving interconnection between private networks and public networks.
Through this integration, terminal devices can flexibly switch between different network environments to meet the diverse communication needs of users.
1.2 Definition of DMR Wide and Narrow Band Fusion Terminal
DMR narrowband fusion terminal is a handheld device that integrates DMR digital analog integrated intercom, public network communication, and other multiple functional modules.
It can automatically switch between narrowband and broadband networks, enabling various forms of communication such as voice, video, and data.
This terminal device not only has the voice communication function of traditional walkie talkies, but also supports high-definition video calls, image transmission, data collection, positioning and other functions, providing users with more comprehensive communication services.
2、 Characteristics of DMR Wide and Narrow Band Fusion Terminal
2.1 Multi mode communication function
The DMR narrowband fusion terminal is equipped with various communication modules, such as public network nationwide intercom, DMR digital analog integrated intercom, and Tiantong satellite phone.
In public network mode, it supports professional cluster functions such as voice group calls, video single calls, multi-party video calls, broadcast groups, and temporary groups, making it simple and convenient to implement.
At the same time, the high-definition camera and display screen combined with a professional dispatch console can achieve professional dispatch functions such as voice dispatch, image and video feedback, data collection, GIS map action trajectory playback, etc.
When switching to DMR intercom communication mode, the original system base station can be used, significantly reducing network construction costs.
In narrowband mode, the voice is clear and loud, the signal is stable and reliable, and no operator base station is required. Short distance voice single call, group call, group broadcast call, SMS, roaming and other operations can be carried out.
2.2 High precision positioning function
Some DMR narrowband fusion terminals are equipped with Beidou RTK high-precision positioning carrier phase difference technology, also known as differential positioning technology.
This technology obtains satellite positioning data through ground base stations, compares it with the actual position, calculates the positioning error, and can achieve high-precision positioning at the sub meter or centimeter level.
This high-precision positioning function can be applied to complex environments such as ports, construction sites, freight yards, railways, petrochemicals, fisheries, forestry, emergency rescue, as well as areas with safety hazards, achieving intelligent and refined management.
2.3 Explosion proof function (partial terminals)
Some DMR wide and narrow band fusion terminals have explosion-proof functions and are suitable for environments that are flammable, explosive, contain dust, gases, etc.
For example, the Shield Soul H6 explosion-proof intercom terminal adopts 4G full network, Android operating system, and high-speed processor, and also has DMR private network intercom function, which can make real-time calls to improve team collaboration efficiency.
The scanning head equipped with it can quickly and accurately scan barcodes and QR codes, facilitating data collection.
RTK high-precision positioning system provides users with precise positioning services.
This terminal can be transmitted through 4G/WiFi network and matched with the command and dispatch integration platform to achieve real-time video, intercom, electronic fence, trajectory playback, cloud storage, SOS linkage alarm and other functions, providing safe and efficient solutions for industries such as coal mines, chemical plants, petroleum, pharmaceuticals, and gas.
