KJJ12 Mining Intrinsic Safety Gateway
KJJ12 intrinsically safe gateway for mining is used to achieve network interconnection above the network layer in the coal information network
Product Overview
KJJ12 intrinsically safe gateway for mining is used to achieve network interconnection above the network layer in the coal information network, and Ethernet is implemented through circuit board processing RS485、 With CAN signal conversion, multiple interfaces can be used to connect various monitoring system substations and terminals.
safe and reliable
Fully sealed 304 stainless steel explosion-proof shell, observation window made of organic glass, intrinsic safety type, with coal safety certification and explosion-proof qualifications, suitable for harsh working conditions.
Multiple types of interfaces
There are many types and quantities of interfaces that can be easily connected to the existing network of coal mines. There are also many types and quantities of devices that can be connected to meet various on-site needs.
Easy installation and debugging
The gateway is connected to the host through a mining communication cable. Click the host power button, and the gateway will automatically work when powered on, with wireless debugging operations. The main parameters can be directly configured through software.
Working Principle
Multi protocol signal access and conversion
The gateway receives different protocol signals through Ethernet, RS485, and CAN interfaces, and processes them internally through the circuit board processing unit for protocol parsing and format conversion.
Intrinsic safety signal processing and forwarding
-
The converted signal is processed by an intrinsic safety circuit (including explosion-proof measures such as current limiting and isolation) and output through wireless modules (such as Wi Fi/4G/5G) or Ethernet to achieve safe communication between underground equipment and surface systems.
Dual mode redundant transmission
Supports wired (Ethernet/RS485/CAN) and wireless dual channel transmission, automatically switches to a backup link when the main link is interrupted, ensuring real-time data transmission; Simultaneously equipped with signal verification and retransmission mechanisms to ensure transmission reliability.
