The HQL Power Plant is mainly engaged in thermal power generation, comprehensive utilization of fly ash and research and development of thermal power generation technology.
It is one of the main power points of the national“West-to-East Power Transmission” project.
In Mar 2018 HQL Power Plant required IFLY to build up a stable private LTE network aiming to:
① Rapid Emergency Response
② Manage High-risk Work
③ Computer Inspection
④ Build A Smart Power Plant
⑤ Build A Secure & Reliable Private Network
① Unreliable Communication System Makes Blackout Worse
Unable to detect the accidents immediately → Require a reliable communication Network
Unable to isolate the accidents immediately → Require a real-time video monitoring for surveillance
Unable to dispatch the first responders immediately → Require a trunking system for quick response
② Hard to Communicate in Remote Areas
It is too far or too expensive to lay fiber in remote areas → Require communication in remote areas
Natural disaster may damage fibers → Require recovering communication rapidly
Existing public network is unreliable and unsafe → Require providing more protections for communication network
③ Hard to Provide Safety Managements and Accidents Location
Requirement for unattended management mode of electric power plant → Require full-coverage, high-definition and real-time surveillance
Requirement for accidents location & recover in electric power plant → Require reliable communication under electromagnetic interference
Requirements for reliable monitoring in electric power plant → Require centralized management, visualization monitoring & dispatching
According to the HQL Power Plant's actual condition, IFLY made a solution: Distributed base station combines with mobile base station to cover the whole factory area.
Features of the Solution
● Combine fixed and mobile to reduce costs.
● Take advantage of the mobility of portable base stations to cover any production area within the plant.
● Take advantage of the strong 400MHz carrier diffraction capability to form a good coverage of dense metal pipes.
● Conducive to the step-by-step network implementation. Portable base stations can be quickly deployed with 15minutes.
UP:9Mb/ DOWN: 100Mb
UP: 19Mb/DOWN: 50Mb
UP: 28Mb/DOWN: 40Mb
Three network bandwidth modes can be configured according to the actual use of the power plant.
① Fixed Base Station Construction
② Portable Base Station Construction
① Outdoor: The following tests take 2~3Mb/channel video as an example.
② Indoor Turbine
According to this test, 80% of the production area's video transmission quality meets the needs of HQL Power Plant
Portable base station is used for coverage blind spots and works well. In this way no blind zone coverage in the production area can be achieved.
