Background of the Solution
01
The newly established coal mining company has a complex production scenario, requiring efficient communication and scheduling support for underground mining, above-ground command, and equipment monitoring. Traditional scheduling systems face issues such as limited capacity, single access methods, and delayed scheduling functions, which gradually fail to meet production demands. The Nanjing Shenou CommunicationSOCKT642softswitch scheduling system is based on the NGN (Next Generation Network) architecture, featuring a modular design, supporting SIP protocol, and possessing high reliability, flexible scalability, and multi-service integration capabilities, effectively addressing challenges in coal mine communication such as cross-regional scheduling, multi-system linkage, and safety control, providing reliable communication support for production safety and efficiency improvement.
Project Requirements
02
1. Basic Communication Requirements: The system should have high stability,ensuring normal operation under high concurrent call conditions while being compatible with mainstream telephone networks and communication protocols. Existing administrative office analogtelephonecommunication equipment in the coal mine needs to be integrated into the operation, ensuring smooth communication between underground workers, above-ground dispatchers, and office personnel from various departments.
2. Safety Scheduling Requirements: Support strong insertion, strong removal, monitoring, and other scheduling commands to meet emergency command scenarios; recording functions should cover all calls for post-event tracing. The core telephone system adopts dual-machine hot backup,ensuring the system can continue to operate normally in the event of a main server failure.
3. System Integration Requirements: Seamlessly connect with underground gas monitoring, video surveillance, and broadcasting systems to achievean emergency response mechanism of “one-click trigger, multi-system linkage.”
4. Easy Management and Maintenance: Provide an intuitive management interface for administrators to configure and manage the system, while also having comprehensive monitoring and logging functions,facilitating fault diagnosis and system optimization.
5. Scalability Requirements: Reserve expansion interfaces to support future additional terminals.
Solution Implementation
03
Core Layer: Deploy2sets of ShenouSOCKT642 explosion-proofsoftswitch equipment, one main and one backup, supporting load balancing,ensuring the reliability of the scheduling system.The system supports major functions such as call control, resource allocation, protocol processing, routing, authentication, billing, etc., while providing rich telecom-grade call features, IP voice, video, electronic fax, conferencing, recording, IVR, TTS, Radius billing, and a variety of value-added services, and offers programmable capabilities to third parties.
Access Layer: Configure1 set ofSOT600-IADvoice gateway (analog gateway), integrating the coal mining company’s office analog phones into theIP network; deploy 1 SOD8280 touch screen dispatch console as the dispatch operation center, which is equipped with full-call voice, selective call voice, and video phone, and has a one-click emergency call function.
Terminal Layer: Deploy IP phones in the above-ground office, and connect intrinsically safe analog phones underground through couplers, with terminals registering to the softswitch host via the IP network.
Value of the Solution
04
▋ Flexible Expansion
The Nanjing Shenou Communication SOC KT642 softswitch system host supports smooth capacity expansion. When the coal mining company scales up and the number of users increases in the future, there is no need to replace core equipment; only additional modules need to be added to meet the demand, reducing long-term operation and maintenance costs.
▋ Safety Redundancy
Utilizing dual-machine backup, when the system is normal, the main machine operates, and the system automatically checks at set intervals. If a problem is detected, the system can automatically switch to the backup machine to continue operation, ensuring that the normal operation of the system is not affected.
▋ Convenient Management
The network management system monitors and manages the network, providing graphical real-time monitoring of servers, devices, and calls, offering statistical data on system operation information, and automatic alarm functions in case of faults, significantly reducing operational maintenance costs.
