Caltta Talks about Convergent Solution for Now & Future
×
Liaohe Oilfield is China's largest heavy oil and high-viscosity oil production base, spanning across Liaoning and Inner Mongolia, covering an area of nearly 100,000 square kilometers. It has complex geological conditions and a diverse range of oil types.
As a crucial support force for the oilfield, the Liaohe Oilfield Fire Brigade has been responsible for fire rescue tasks in the oilfield and surrounding areas since its establishment in 1970. It consists of 8 brigades and 20 teams, covering a wide service area with significant responsibilities.
The original wireless private network system of the Liaohe Oilfield Fire Brigade was first built in 1985 and upgraded to an analog trunking communication system in 2001. For many years, this system has played a crucial role in fire emergencies and rescue operations. However, with urban development and increasing communication demands, the system now faces the following issues:
Outdated Technology
The existing wireless private network system is still analog, which offers low security and is susceptible to interference and eavesdropping.
Aging Equipment
Some core equipment, such as relay stations, has been in service for over 20 years, leading to frequent malfunctions and difficulty in maintenance.
Discontinued After-Sales Support
The original manufacturer is no longer able to provide after-sales service for core equipment such as relay stations.
System Heterogeneity
The system uses various brands of equipment, a mix of digital and analog devices, with poor compatibility and complex operation and maintenance.
To address the increasingly complex situation and improve fire-fighting and rescue capabilities, the fire brigade urgently needed to build a new professional wireless emergency communication system. This system would not only serve as an effective tool for fire emergency command and dispatch but also act as a backup communication method for oilfield authorities and various oil extraction zones, as well as joint stations, in case of extreme situations such as natural disasters causing public network communication disruptions.
Caltta has tailored a wireless private network communication solution based on the ECS multi-site narrowband digital trunking system for the Liaohe Oilfield Fire Brigade.
Project deployment includes:
• 19 sets of PR900 digital relay stations.
• 22 sets of PM790 digital base stations.
• 78 sets of PM790 vehicle-mounted radios.
• 209 sets of PH790Ex explosion-proof radios.
• Dispatch/Network Management System PD200, recording system MRS, PSTN telephone interconnection system.
The dmr trunking system adopts an IP-based network to enable unified communication and dispatch across the Liaohe Oilfield area. It supports multiple services such as voice, positioning, SMS, and data, and boasts strong expansion and interoperability capabilities.
Wide Coverage
The design adopts a regional approach, with base stations having high transmission power and high sensitivity, allowing for extensive coverage with a minimal number of base stations. All sites are interconnected via IP, creating a unified communication network.
Large Capacity
Cluster technology is used to enable channel sharing and load balancing, significantly increasing call capacity and resource utilization.
High Reliability
Dedicated frequencies are used for exclusive network use, ensuring stable and reliable signal coverage. Additionally, the system has a strong fault tolerance capability, ensuring that even if some sites are interrupted, the remaining sites can continue to operate independently.
High Security
The system has local access management features, with strict identity verification for terminals. Unauthorized devices cannot access the network. It supports end-to-end encrypted communication, eliminating eavesdropping risks.
Rich Functionality
The system supports individual calls, group calls, all calls, emergency calls, real-time positioning, trajectory playback, SMS, recording, and other features to enhance command and dispatch efficiency.
Telephone Interconnection
Through a PSTN gateway, the system enables seamless communication between the command center and front-line team members, integrating wired telephone systems.
Flexible Expansion
The fully IP-based architecture supports flexible expansion of sites, channels, and services, and is compatible with third-party platforms and custom development.
In recent years, Caltta's private network communication products, with their outstanding technical capabilities and industry adaptability, have been continuously applied in the oil and petrochemical industry. These solutions, for exapmle, dmr solutions, cover the entire industry chain, including oil and gas exploration and development, offshore oil platforms, oil and gas storage and transportation dispatch, petroleum refining, chemical parks, and chemical materials manufacturing, gaining trust and recognition from industry clients.
The Liaohe Oilfield project serves as another benchmark case for Caltta's private network solutions, successfully achieving large-scale network coverage in the oilfield fire-fighting scenario and effectively improving emergency communication capabilities. Moving forward, we will continue to focus on customer needs, deepen industry application scenarios, and provide more intelligent and customized private network communication solutions to support the digital transformation and safety production of the petrochemical industry.
