煤矿通信怎么选？这3款CAN转换器一用就稳
1.矿用本安型CAN-RS485转换器
1. Mining intrinsic safety CAN-RS485 converter
这类转换器带煤安（MA）认证、本质安全型，适合井下易燃易爆环境，抗干扰、隔离保护强。
This type of converter is certified by Coal Safety (MA) and is inherently safe, suitable for underground flammable and explosive environments, with strong anti-interference and isolation protection.
用法：将井下CAN总线传感器（瓦斯、风压、水位、温度）与RS485采集设备/分站对接，实现不同总线信号转换，把现场监测数据稳定上传到井下监控分站，再汇总到地面调度中心，为安全监测提供实时数据。
Usage: Connect the underground CAN bus sensors (gas, wind pressure, water level, temperature) with RS485 acquisition devices/substations to achieve different bus signal conversion, stably upload on-site monitoring data to the underground monitoring substation, and then summarize it to the ground dispatch center to provide real-time data for safety monitoring.
2.CAN光纤中继转换器（CAN转光纤）
2. CAN fiber optic relay converter (CAN to fiber optic)
井下距离长、电磁干扰大，双绞线传输受限，CAN转光纤转换器可延长通信距离、抗强干扰。
The underground distance is long, electromagnetic interference is high, and twisted pair transmission is limited. The CAN to fiber optic converter can extend the communication distance and resist strong interference.
用法：用于井下长距离通信，把CAN电信号转为光信号，传输距离可达几公里至20公里，实现工作面、泵房、变电所与地面机房的可靠通信，解决井下电磁干扰大、传输距离不足的问题，保证数据不丢包、不掉线。
Usage: Used for long-distance communication underground, converting CAN electrical signals into optical signals. The transmission distance can reach several kilometers to 20 kilometers, achieving reliable communication between the working face, pump room, substation, and ground machine room. It solves the problems of large electromagnetic interference and insufficient transmission distance underground, ensuring that data is not lost or disconnected.
3.CAN转以太网转换器（CAN转TCP/IP）
3. CAN to Ethernet converter (CAN to TCP/IP)
用于煤矿信息化、远程监控，实现CAN设备接入以太网与上位机、PLC、云平台通信。
Used for coal mine informatization and remote monitoring, realizing CAN device access to Ethernet and upper computer PLC、 Cloud platform communication.
用法：将井下CAN总线设备（皮带保护、液压支架、排水控制）数据转为以太网信号，直接接入矿用以太网，地面SCADA、PLC、监控平台可远程读取、控制设备，实现井下设备远程监控、故障诊断、数据存储，提升煤矿自动化与智能化水平。
Usage: Convert the data of underground CAN bus devices (belt protection, hydraulic support, drainage control) into Ethernet signals and directly connect them to the mining Ethernet. Ground SCADA, PLC, and monitoring platforms can remotely read and control the equipment, achieve remote monitoring, fault diagnosis, and data storage of underground equipment, and improve the automation and intelligence level of coal mines.
