Fiber Optic Cable Hybrid Networking Solution

Fiber Optic Cable Hybrid Networking Solution

Various types of pipelines in the pipeline corridor are complicated, the laying distance is long, data transmission in such an environment is easy to be lost or interfered with, Shenzhen Yuantong has developed a fiber optic cable hybrid networking integrated pipeline corridor fixed emergency communication system for the integrated pipeline corridor by using the experience of the development and production of domestic and foreign industrial telephones in the fields of highway, railroad, mine, petroleum, chemical, metallurgy, electric power and so on, which is accumulated for many years, and the system is a set of optical fiber The system integrates the functions of fiber optic transmission, hybrid networking, soft exchange, management and dispatching, external line out, digital recording, call positioning, 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 is composed of two parts: visual intercom and management platform, and provides users with audio intercom based on the on-site WIFI environment, and provides users with audio intercom. It is composed of two parts: visual intercom and management platform, based on the WIFI environment, providing users with audio intercom, video intercom, SIP call, picture upload, video upload, data storage and traceability management, real-time monitoring in the process of moving, 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 communication system consists of softswitch servers, network switches, fiber optic telephone access hosts, dispatch consoles, dispatch phones, fiber optic telephone hosts, fiber optic telephone subs, etc. The composition and connection diagrams are shown below:

As shown in the above figure, the IP core dispatching server, dispatching console, fiber-optic telephone access host and intercom broadcasting alarm phone are installed in the monitoring center, and the equipment is connected to the network of the monitoring center. Installation of fiber-optic telephone host in the equipment mezzanine in the pipeline corridor, installation of fiber-optic telephone sub-machine in the cabin, fiber-optic telephone host in order of direct fiber-optic connection into a ring access fiber-optic telephone access host to ensure that the fiber-optic telephone host communication network redundancy and high availability, fiber-optic telephone sub-machine through the telephone line connected to the fiber-optic telephone host, a sub-machine failure will not affect the normal work of the other sub-machine, the gas cabin needs to be used in the explosion-proof products. Gas cabin should use explosion-proof products.

1. Program value highlights

1) Cost-effective, mature technology, safe and reliable.

(2) two-core cable to solve the power supply, signaling, and voice transmission, construction and wiring is simple and convenient, if you need to broadcast function requires input DC12V or AC220V power supply.If broadcasting function is required, it needs to input DC12V or AC220V power supply.

4）No need to set any parameter for the sub-machine, it is ready to be installed and used.

5）It adopts international standard SIP protocol, which is a set of open system, products following this standard can access the system, and the compatibility is very strong.Compatibility is very strong, so that the user has no worries;

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

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

8) All the phones are registered to the IP core scheduling server, the office phone of the management center can also access the system, and the downtime of the management workstation with console software installed does not affect the normal use of the system.

9) 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.

10) 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.

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

12) 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.
