typical case: 2. dedicated communication network system integration

2.1 central line communication system integration project of south-to-north water diversion

☆ construction unit: south-to-north water transfer middle route construction management bureau

☆ project scale: 41.182 million yuan

☆ duration: september 2013-october 2014

☆ main work content: this project starts from the head hub of taocha canal, xichuan county, henan province and ends at tuancheng lake in beijing and outer ring river in tianjin. the total length of the line is 1431.945km. the entire project adopts advanced information collection technology, information processing technology, and automated control. technology, computer network technology, communication technology and modern operation, maintenance, management technology and concepts, build a complete and advanced automatic dispatching and operation management decision support system on the middle route of the south-to-north water transfer project, and conduct comprehensive operation and maintenance of the middle route project and management to ensure timely, effective and safe water transfer across the line. the communication system project is divided into program-controlled switching system, communication transmission system, communication clock synchronization and integrated network management system. the project covers equipment installation, hardware testing and hardware testing of 5 sub-bureaus, 37 management offices, 207 on-site station transmission systems, switching systems, power supply systems, air conditioning systems, and fire-fighting networking systems along the main water supply canal of the middle route of the south-to-north water transfer project in beijing, tianjin, hebei, and henan. system debugging.

☆social benefits: the completion of the communication system integration project of the south-to-north water diversion middle route has realized networking with the original beijing-shijiazhuang section communication system, forming the communication basis for the operation of the automated dispatching system of the south-north water diversion middle route, providing full-line data transmission, voice calls, computer room environment control, etc. the service has ensured the operation and management of the automatic dispatching system of the middle route of the south-to-north water diversion project, and has made far-reaching contributions to the smooth water transfer of the middle route of the south-to-north water diversion project of the national century project.

☆ highlights in technology and management: the communication system integration project of the south-to-north water diversion middle route has long construction lines, many sites involved, and the construction progress of each site is difficult to unify. the inconsistent delivery schedule of each construction interface leads to insufficient effective construction period and difficulty in protecting semi-finished products. in order to ensure the smooth implementation of the project, the company’s senior leaders, the project management department and the mid-line engineering headquarters directly took the lead and established the mid-line communication integration project department composed of softswitch and transmission professional engineers and senior project managers. at the same time, the tianjin project team was established. , hebei project group, henan yellow river north group, henan yellow river south group and other 4 project groups. all the engineering construction personnel fulfilled their duties, worked overtime, worked hard and faced difficulties, and finally completed all the engineering tasks with high quality and high standards, and handed over a satisfactory answer to the country and the people.

2.2 gezhouba group's three-network integration system construction project

☆ construction unit: gezhouba (yichang) communication engineering co., ltd.

☆ project scale: 5.55 million yuan

☆ duration: november 2011-june 2012

☆ main work content: gezhouba group's triple play system includes three parts: ngn softswitch system, ip bearer network system, and optical fiber access network system. through the new softswitch platform, it will be used as a fixed telephone service gateway to interconnect with china mobile, china telecom, and china unicom; a new ip bearer network will enable fixed telephone, broadband, and digital tv services to be carried on the ip bearer network; a new set is added the epg server integrates the existing digital tv into the newly-built ip bearer network, and provides triple play services including digital tv services through the newly-built epon access system.

☆social benefits: after the completion of the system, gezhouba city will provide a brand-new three-network integration and fiber-to-the-home integrated communication service business to meet the development needs of communication operations and at the same time provide a set of advanced integrated business operation platform for gezhouba communication company , making the communication business operation technology advanced, safe and stable, improving the core competitiveness and service quality of gezhouba communication operation network, and enhancing user service capabilities and satisfaction.

☆ highlights in technology and management: the project involves the cutover of the original voice and broadband services, which is difficult to implement, heavy cutover tasks, and high technical risks. the company meticulously organizes the construction, deploys experienced commissioning engineers, and formulates a comprehensive and detailed cutover plan to ensure the smooth cutover of existing network users to the triple play system, successfully complete the construction of this project, and meet the design requirements and operational requirements of the project.
