Explosion-proof digital intercom
BF-TD930 digital explosion-proof walkie-talkie is a high-performance, multi-functional digital terminal product,Support DMR conventional, DMR cluster, PDT conventional, PDT cluster, analog conventional and other mainstream communication systems,Digital general supports rich personalization features,It includes full-duplex call, same frequency relay, AD hoc network, and adaptive intelligent IP interconnection system。

BF-TD930 数字Explosion-proof walkie-talkie is a digital terminal product with high performance and multiple functions,Support DMR conventional, DMR cluster, PDT conventional, PDT cluster, analog conventional and other mainstream communication systems,Digital general supports rich personalization features,It includes full-duplex call, same frequency relay, AD hoc network, and adaptive intelligent IP interconnection system。The whole machine meets the test requirements of the national military target, meets the test requirements of the US military standard MIL-STD-810G, and passes Ex ibIIB T4 GB gas explosion-proof certification and Ex ibD21 T130℃ dust explosion-proof certification。The product adopts military-grade design requirements, meets IP68 dustproof and waterproof, color LCD display, visible under strong light, operation at a glance。


Double explosion protection

The BF-TD930 is a dual explosion-proof certification (Ex ibIIB T4 GB, Ex ibD21 T130℃)数字Explosion-proof walkie-talkie, a PDT/DMR explosion-proof walkie-talkie developed for fire, petrochemical, oil refinery, natural gas and other workplaces, to provide safer and more reliable communication guarantee for personnel who need to work in dangerous environments of explosive gases and combustible dust。


AD hoc network

BF-TD930 Explosion-proof walkie-talkiesUsing multi-hop multilevel relay technology, only relying on the relay function of the terminal itself, each AD hoc network radio into a communication signal source, so as to form a powerful intercom network, can realize the non-center AD hoc network。It has the characteristics of saving frequency resources, convenient use, easy to carry and rapid deployment, and greatly expands the wireless communication distance to achieve signal coverage in special environments。(Optional function)


Superheterodyne circuit

The product adopts the new superheterodyne circuit design scheme, and the RF performance is greatly improved。In the signal edge zone, large range, long-distance communication and other scenarios, the coverage is wider, and the receiving sensitivity is higher, further reducing the cost of customer network construction, and extending the communication to unprecedented areas。Especially in the cross-zone switching in the mobile use scenario, it ensures the stable reception of the limit signal, ensures the timely and efficient communication of key information in a wider range, and ADAPTS to the needs of customers for efficient remote communication and weak signal reception。


Dual tactical covert mode

Receiving command information is the key to the execution of tasks. BF-TD930 designs a dual tactical stealth mode of sound and light to meet the application requirements of covert combat communication. During communication, the terminal can be turned off to hide its whereabouts by sound and light, and the user can be prompted to receive information through tactile vibration to avoid errors and leakage of key commands。For situations where voice calls are not convenient, send quick short messages via programmable keys, providing users with unmatched reliability。


Single frequency relay

BF-TD930 Explosion-proof walkie-talkiesSupports the same frequency relay function in the conventional PDT/DMR mode,Used as a handheld relay station,Can help customers quickly establish the same frequency relay network,Establish A transit channel for terminals A and B in a certain area,Expand the original interworking range of terminals,It makes up for the shortcomings of short communication distance and easy serial frequency of traditional walkie-talkie。


Advanced encrypted communication

BF-TD930 Explosion-proof walkie-talkiesBased on PDT/DMR dual standard, it supports a variety of encryption technologies such as common encryption algorithm, AES256 and ARC4 advanced algorithm encryption, and dynamic secret key encryption, encrypting voice and data signals, and highly ensuring the security of communication content between the scheduling layer and the terminal layer。


Full duplex communication

BF-TD930 Explosion-proof walkie-talkiesProvides a new way of calling, walkie-talkie is no longer limited to the traditional intercom, can achieve two-way calls between terminals, provide more timely communication at key moments, communication without waiting, call quality is better, more efficient。


Beidou /GPS satellite positioning

BF-TD930 Explosion-proof walkie-talkiesSupport Beidou /GPS a variety of high-precision positioning, can achieve information reporting, data short message query, data compression and speed detection, with the system platform can obtain real-time user dynamic information and behavior data and realize visual command and dispatch through the platform。(Optional function)


Long endurance

The product uses the latest lithium polymer technology, with an optional 3350mAh large-capacity battery, which can easily achieve 24 hours long battery life, so that users can easily cope with the uninterrupted use of daily work。


IP68 protection

The whole machine adopts precision and strong structure technology +IP68 dustproof and waterproof design, even in rain, dust, high temperature, cold and other harsh conditions, it can still provide clear and loud voice and stable and reliable communication。


TTS voice broadcast

BF-TD930 Explosion-proof walkie-talkiesIt can provide SMS broadcast function (TTS), which can use text to voice broadcast without manual browsing, and can listen to SMS content without viewing, easily freeing users' hands and eyes。


Multiple warning functions

BF-TD930 Explosion-proof walkie-talkiesSupport 5 types of alarm, 3 kinds of emergency alarm (separate operation alarm/fall alarm) function, for example, in the event of an emergency, the emergency alarm function can be used to inform the emergency situation, and the rear staff can quickly find the person in distress, timely support and rescue。


Rich versions and features

Provides a powerful and flexible system version selection,Support standard PDT/DMR dual versions,It is suitable for various communication systems: standard conventional mode, standard cluster mode, same frequency relay mode, AD hoc network node mode, North peak virtual cluster mode, and North Peak scheduling system mode,To provide users with more and more flexible communication service choices。
