All-Fiber Networking Solutions

All-Fiber Networking Solutions

All kinds of pipelines in the pipeline corridor are complicated, the laying distance is long, the data transmission in such an environment is easy to be lost or disturbed, Shenzhen Yuantong uses the development and production experience of domestic and foreign industrial telephones in the fields of highways, railroads, mines, petroleum, chemical industry, metallurgy, electric power and so on accumulated over the past years to develop an all-fiber-optic networking fixed emergency communication system for the comprehensive corridor, which is a set of fiber-optic transmission network, softswitch, management and dispatching, outgoing line, digital recording, call location, broadcasting and shouting and other functions. The system integrates the functions of fiber optic transmission network, softswitch, management scheduling, outgoing line, digital recording, call locating, broadcasting and shouting, etc.; Shenzhen Yuantong utilizes the mature WIFI, cell phone, APP and computer software technology to develop a set of multi-functional handheld wireless visual intercom system for the application environment of the corridor, which consists of two parts: visual intercom and management platform, and based on the on-site WIFI environment, it can provide the user with Audio intercom, video intercom, SIP call, picture uploading, video uploading, data storage and traceability management, real-time monitoring during the moving process, remote assistance, precise positioning and other on-site communication and management means. Thus, it forms an overall comprehensive solution combining fixed communication, wireless communication and on-site control.

1. System components

The fixed communications system consists of softswitch servers, network switches, fibre-optic telephone access hosts, dispatch consoles, dispatch handsets, fibre-optic telephones, etc., and its composition and connection diagrams are shown below

As shown in the above figure, our independent products IP core dispatching server, dispatching console, fiber optic telephone access host and intercom broadcasting alarm microphone are installed in the monitoring center, and the equipment is connected to the monitoring center's network. Installation of fiber-optic phones in the corridor, fiber-optic phones in order to use fiber-optic direct connection into a ring access fiber-optic phone access host, to ensure that the fiber-optic phone communication network redundancy and high availability, the gas chamber needs to use explosion-proof products.

2.Program value highlights

1）Strong anti-interference, mature technology, safe and reliable.

2) All fiber optic transmission, all digital;

4) the use of international standards SIP protocol, is an open system, follow this standard products can access the system, theCompatibility is very strong, so that the user has no worries;

5) The system provides a secondary development interface, which can be seamlessly integrated with the pipeline corridor platform.

6) Fixed communication, wireless communication and on-site control are combined.

Main functions of the system

3.Main functions of the system

1）Visualized scheduling graphical interface can effectively view the various states of the management of telephone terminals including registration status, call status, business status, etc. The console software runs on WIN 7 and above operating system platforms, and the interface design is compatible with the touch screen, and adopts the split-screen technology, which can be displayed on multiple screens.

2) The console software can visualize the grouping and status of each telephone terminal, and can realize the scheduling functions such as calling, transferring, forcibly inserting, forcibly dismantling, listening, broadcasting, telephone recording, telephony and conferencing, etc., and provide interface protocols to realize the linkage function with other systems.

3) IP core scheduling server takes the standard SIP protocol as the core, supports the third-party equipment access, external line access, supports the international standard G.722 wide-band voice coding, and combines with the unique echo cancellation technology to provide high-fidelity, high-definition sound quality.

4) IP core scheduling server adopts linux operating system, supports 5000 terminals access, 400 simultaneous calls, to ensure long-term safe and reliable operation of the system.

5) All telephones are registered to the IP core scheduling server, and the office telephones of the management center can also be accessed to the system, and the downtime of the management workstation installed with the console software will not affect the normal use of the system.

6) The telephone adopts integrated design to ensure the simplicity, beauty, reliability and convenience of construction and maintenance of the telephone, aluminum alloy material protection level IP67.

7) The phone needs to have a protective front cover to ensure that the equipment is placed and used for a long time after the handle, buttons, indicators and other components without dust and dirt.

8) The telephone has sound and light indication when ringing, so that the personnel in the pipeline corridor can quickly and accurately answer the phone.

9) the telephone to increase the amplifier module, external broadcast speakers, you can realize a single broadcast, partition broadcast, all broadcasts, music broadcasts, timed broadcasts and other functions.
