The Buenoptic New No-cascading long distance Canbus fiber Optic converter just signed the contract with Turkey system integrator who is to install the new Canbus fiber optic converter to their fire safety systems. Because the traditional CAN BUS fiber optic converter has the defects problem of cascading,which will stop work working when distance is long or bit rate is high.Buenoptic new canbus fiber optic converter has successfully solved this problem. In this project the longest distance is 5.5km,the old converters can't reach this distance, so the integrator finally choosed us.

Project Overview
With the rapid development of the national economy and the state of the strong commitment of the infrastructure, China's surge in demand for steel, the steel mills to increase productivity and steel quality, the general DCS control system to replace the conventional analog control. DCS control system, via Industrial Ethernet in different plant instrumentation and PLC connected to the same network, and remote monitoring.

ABB has the steel and nonferrous metals industry-leading automation solutions provider, established long-term cooperation relationship with many steel makers in China. Automated reconstruction projects in several major steel mills in Henan, one of the main providers of industrial Ethernet switch and serial communication products together to provide customers with the perfect solution.

In Steel DCS,they used BUENOPTIC's industrial ethernet switches products, including HFB5, HFB5-SC, HFB8M-2SC and HFB24-2SC and other solution features include:

By RingOn function ring network self-healing time is less than 15ms, so as to ensure real-time and reliability of the network;
Each workshop fiber connectivity, support for long distance transmission, strong anti-EMC / EMI capacity;

IP30 degree of protection, industrial DIN rail installation, to meet the steel harsh environmental requirements;

Support user-defined alarms, and via Email sent, providing the operator real-time alerts;
WEB-based management approach, to facilitate the system for remote maintenance and management.

In November,our Canbus Fiber Optic modems were mounted to a fire alarm system in Turkey,the integrator is Honey well and we are the product supplier.

Project Introduction

The main bridge of Taizou Yangtze River Bridge is the first triple-towered double-super-span steel suspension bridge in the world. The full length of main bridge and the approach is 9,726 m, the width of deck is 33 m.The bridge shortened the highway travel distance between Taizhou and Changzhou from 150 km  to 30 km and reduced travel time from 1.5 to 0.5 hours. The solution provider applied Bueno industrial ethernet switches in the network infrastructure of the Integrated Environmental Monitoring System, which refers to the process of implementing environmental data collection and broadcasts.

System Requirements

1.Serial device server integrated Ethernet switches are required to connect peripheral serial devices and form a redundant fiber ring. 2.The devices should be able to work under damp and high temperature harsh ocean environments. 3.The devices should be anti corrosion due to the strong salt spray fog. 4.High EMC performance for the usage of the devices in high electromagnetic interference.

Buenoptic Solution

Buenoptic offers the network solution for the whole system, which is consists of vehicle control, bridge information broadcasting, power monitoring, bridge weather station, steel structure drying, and aircraft warning light systems. There are 23 pcs of industrial Ethernet switches deployed in the North and South fast Ethernet redundant fiber rings that control 33 message sign boards, 39 street lights, 39 power monitoring stations, 4 bridge weather stations, 5 vehicle license plate recognition devices, and 24 aircraft warning lights on the top of 3 200m height bridge towers. The system ensures all traffic and weather information are reliably broadcasted and keeps traffic running smoothly and safely.

The erosion of the materials caused by huge salt spray fog brings a huge challenge for the devices working in such an river environment. However, Buenoptic industrial Ethernet switches are specially designed for such a harsh environment, and its outstanding anti-corrosion performance with the conformal coating design, wide operation temperature and high EMC level features enable the devices to perform with unprecedented reliability and stability.

Through years efforts,a medium-sized wind farm was finally completed in Eastern Euope and Buenoptic RS-485 redundant ring fiber optic modem also became one important part of the wind farm's networks system. The whole project needed 175 pieces of DIN Rail RS-485 redundant ring fiber optic modems to combine a redundant ring fiber optic network.RS-485/232/Ethernet & Profibus redundant ring networks is quite common in power systems(substation,wind farm,solar plant,ect) due to the safety of ring networks.Once one node is faulty, the redundant ring fiber optic modem will start the self-healing recovery function to maintain the normal work of the whole network,thus the whole network will not be influenced by one faulty node and keep working, which is very important for the power grid systems where the safe network is much more important than anything.

The below is one of the the configuration of the project:
