KTK12 intrinsically safe visual intercom terminal for mining
KTK12 intrinsically safe visual intercom terminal for mining is a terminal device suitable for voice and visual intercom in explosive gas environments underground coal mines
Product Overview
The KTK12 intrinsically safe visual intercom terminal for mining is a terminal device suitable for voice and visual intercom in explosive gas environments underground coal mines. This product has functions such as one key call center, one key call to this group, any dial-up call, and on-site video collection. The intercom terminal has the advantages of clear and loud sound, simple installation, easy maintenance, anti-interference, and light weight.
safe and reliable
Compliant with intrinsic safety, with explosion-proof certification and coal safety certification, possessing explosion-proof, anti-corrosion, impact resistant, and anti-interference capabilities, able to withstand harsh working environments, maintain stable performance, and operate safely.
feature-rich
Visual network intercom, call and answer functions, one click call center or call our group; Keyboard dialing; Terminal status and dialing number display function; Add phone book and query call records; Update and restart.
High sound and image quality
Sound volume ≥ 85dB (A), distortion ≤ 10%; Under the condition of illumination of 50-300lux, the horizontal clarity should not be lower than 400 lines, and the grayscale discrimination level should not be less than 7 levels.
Working Principle
Audio and video data collection and transmission
The terminal collects audio signals through a microphone and video signals through a camera. After analog-to-digital conversion, the signals are transmitted to the network through a 1000Mbps Ethernet optical/electrical interface to achieve real-time uploading of audio and video data.
Network audio and video decoding and playback
-
The terminal receives audio and video data packets transmitted through the network, decodes them in real time through a built-in decoding chip, drives the speaker output through an amplifier, and drives the display screen display through a video signal, achieving bidirectional real-time communication.
Visual intercom interactive control
Users initiate calls through terminal buttons, and the system automatically establishes audio and video channels; The camera captures live footage, the microphone and speaker complete voice interaction, and the network interface ensures stable data transmission, achieving visual intercom between underground and ground.
