Wireless Mesh Network adopted in modernization of Tianjin Railroad Logistics System

Recently, Tianjin Railroad has successfully established a high quality digitalization platform through wireless network deployment. Each patrol is equipped with customized handheld terminals, which wirelessly sends digital and voice data via communication base-stations to Hazardous Materials Identification System (HMIS) and rail-station maintenance system for electronic storage and printing. This ensures the precision, timeliness and security of the data.

“The terminals are important equipments for ensuring safe operation of railroad. Its applications demand for increases in network communication support. Also, as the environment of railroad system is complex, large communication equipments are inappropriate due to high engineering cost, maintenance difficulties and inflexibility. Consequently, simple wireless network is one of the effective solutions. However, topographical issues such as mountains and tunnels will place hash requirements on signal coverage.” Tianjin railroad patrol system representative stated.

The technical team has repeatedly researched, compared and tested several solutions, and has decided to adopt Azalea Networks’ Wireless Mesh Network Technology to construct the wireless platform for the logistic railroad.

Azalea Networks’ Wireless Mesh Network solution combines a fixed line access point with wireless return multi-hop technology to realize large scale mesh network that requires little maintenance, is highly stable and can be expanded or re-configured anywhere anytime. The handheld terminals can accomplish cargo entries, early warning certificates and voice recording, as well as data code download, wireless digital half-duplex conversation, verbal and visual alerts, and wireless data transmission and reception. Point to point and broadcast communications are also supported.

“The deployment of wireless mesh networks in Tianjin logistic railroad shows its capability of good coverage and operations in complex environment.” President of 51CTO.com, largest IT technical website in China , stated.

“Railroad development is founded on safe operation. These handheld terminals satisfy the safety requirements for railroad development. This successful application of wireless mesh network will encourage its use in railroad quarantine, unified cargo monitoring and control, temporary ticketing, station monitoring and control, thus speeding up the process of modernization.
