System Overview:
KT124 Coal Mine Dispatching Communication System is a coal mine dispatching command system developed and produced by our company using the most advanced digital communication technology. It has a fully digital PCM and various types of peripheral communication interfaces. It has a full range of coal mine production dispatching and command functions, which are suitable for large, medium and small mines, mining bureaus and their regions.
The system is mainly composed of ground dispatching host, access gateway, coupler, security distribution frame, ground intrinsically safe telephone set and other equipment. It has the functions of call scheduling, scheduling call users, user calls, user emergency call scheduling, trunk tandem, forced insertion, forced disassembly, etc. Compared with the traditional dispatching system, it has the characteristics of high reliability, flexible deployment, hierarchical dispatching, integrated wired and wireless, multi-standard access, high compatibility and scalability, etc., providing guarantee for coal mine safety production.
KBA18(C) HD camera is an upgraded version of KBA18(B) camera. The volume is one-third of the original size and the weight is one-fourth of the original. It is suitable for installation in all areas underground, especially in small spaces and large equipment underground. The camera is equipped with a 5 million high-definition camera, 5M high-definition resolution, and star illumination. Advanced video compression technology and ultra-low bit rate make the picture quality clearer and more delicate.

KJ725(A) precise positioning system is a third-generation wireless identification system based on UWB (Ultra Wideband) technology, with a positioning accuracy of 10-30cm, which can be comprehensively applied to the precise positioning management of coal mine personnel, vehicles and equipment .
UWB positioning technology uses ultra-wideband pulse signals to achieve high-precision real-time positioning, adopts TOF (Time of flight signal time of flight) algorithm of arrival time difference, and combines its high bandwidth and high waveform resolution to make it have strong anti-interference and positioning It has the characteristics of high precision and truly realizes high-precision positioning. It is currently the most accurate and large-scale application of underground positioning technology.
