Converged communications system solutions

Converged communications system solutions

1. System overview

Many industrial and mining enterprises, such as chemical plants, gas plants, thermal power plants, coal plants, iron and steel mills and port terminals, etc. has a harsh working environment (high noise, high dust, high humidity) and staff mobility and other industry characteristics, and some of the equipment has a high-power, high-noise, strong electromagnetic interference, high temperature, high pressure, etc., through the production of a number of industrial and mining enterprises and outdoor installations for the study Test sound pressure level of more than 70dB places accounted for nearly 80% and have explosion-proof, anti-corrosion and other requirements. In order to effectively solve the communication problems characterized by the production of this industry, the traditional scheduling communication system has been unable to meet the needs of enterprise production. The petrochemical industry is a large-scale factory, the personnel is relatively concentrated, in the event of gas leakage, fire, production failure, power outage and other events, the need to timely explain the situation to the people in the factory, eliminate misunderstandings, stabilize the mood, solve the real problems related to the interests of the masses, and resolve the conflicts and disputes in the embryonic state. Yuantong Converged Communication System is a one-stop solution with standard SIP protocol as the core, integrating the functions of emergency help, PA broadcasting, intercom communication, wireless communication, visualized dispatching, priority management, real-time recording, alarm system access, emergency plan and alarm linkage, etc. It effectively solves the communication problems in the factory area as well as eliminates the blind spots of the call to improve the efficiency and ensure the safety of production management.

2. System components

The whole factory set up a set of host fusion communication system, the system contains all kinds of broadcasting, telephone, amplified voice intercom terminal, wireless intercom and so on. The system adopts all-digital multi-function industrial voice communication system. At the same time, it reserves the interface and protocol for information interaction with other systems.

The main functions of this system are telephone, broadcasting and PA intercom functions, which provide more comprehensive real-time information to help operators to carry out overall operation and improve the intelligence and automation level of control.

The telephone part consists of IP telephone, IP explosion-proof telephone, explosion-proof junction box, IP user unit, dispatching console, softswitch server, network cable, switchboard, system fiber optic cable and so on. The control telephone is mainly set up in places closely related to production, such as some important operation rooms, offices, cabinets, distribution rooms and other manned or frequently inspected positions, the system wiring consists of outdoor trunk wiring and wiring in the building.

The sound reinforcement part is composed of indoor loudspeaker, explosion-proof trumpet loudspeaker, explosion-proof junction box, IP digital power amplifier decoder, centralized power amplifier, cables, network cables, switches, and system fiber optic cables.

Wireless intercom part consists of trunking channel machine, PSTN gateway, outdoor omni-directional glass fiber reinforced plastic antenna, lightning arrester, omni-directional ceiling antenna, digital base station, 4-port fiber optic repeater near-end machine, 5W fiber optic repeater far-end machine, cables, network cables, switches, and system fiber optic cables.

The host cabinet provides third-party systems such as wireless intercom system, fire alarm system and other interconnected communication interfaces.

The system adopts star topology architecture, all the stations are connected to the central switching equipment of the system through the communication fiber, and any damage to the stations or lines will not affect the normal operation of other equipment in the system. Speakers are connected to the system amplifier unit through speaker cables.

The system supports distributed deployment, for the distance from the system center equipment is far away from the device, can be set up on site between the nearest cabinet convergence point, the system switch, centralized amplifier and other equipment set up in the convergence point, while configuring the corresponding networking interface equipment, through the fiber optic cable will be the convergence point equipment and the system center equipment networking.

For the use of the field environment is divided into explosion-proof area, non-explosion-proof area of two kinds of use of the environment, our company for the project designed for the convergence of communication system equipment is divided into explosion-proof equipment and non-explosion-proof equipment of two types, to target different use of the environment.

Explosion-proof equipment are all gas and dust double explosion-proof equipment and explosion-proof level are the highest explosion-proof level C. The level of explosion-proof products can be applied to both gas and dust. This level of explosion-proof products can be applied to ⅡB, ⅡC, T1 ~ T6 temperature groups of explosive gases and dust environments, the protection level ≥ IP66, can be in the high-noise, high-dust environment, long-term stable work, the safety factor is higher.

3. Program highlights

1. All fiber optic transmission, all digital; single-mode fiber network, take 2 cores of fiber to form a fiber optic self-healing ring network, along the emergency telephone and connected to the fiber optic backbone cable, any failure of one emergency telephone will not affect the normal operation of other emergency telephone.

2. Adopting international standard SIP protocol, it is a set of open system, products following this standard can access the system with strong compatibility, so that the user has no worries.

3. Professional and beautiful touch interactive graphical interface, professional UI design; visualization of the scheduling graphical interface, interface design compatible with the touch screen, the use of split-screen technology, can be displayed on multiple screens.

4. Unified integration, multiple call broadcasting methods to enhance communication efficiency;

5. Unified platform, service internal paging, early warning alarm and video monitoring;

6. Rich extended functions, docking safety monitoring system, enhance safety production management;

7. Business integration: a single system can support voice help, video linkage, fire alarm, access control and other services, and through a unified console interface to complete the monitoring and listening, business consulting, alarm and help.

8. High-definition sound quality: the system supports international standard G.722 broadband voice coding, combined with the unique echo cancellation technology, compared with the traditional PCMA coding, high-fidelity, high-definition sound quality.

9. Noise canceling function: Far Eastern's unique patented noise canceling technology can completely eliminate 115dB of noise in the noise environment, so that the other party can not hear the noise but only hear the human voice.

10. Production and office telephone integration: the production area sound reinforcement intercom system and office administrative office telephone system are both independent and interconnected.

11. Integration of wireless intercom system: wireless intercom is easy to carry, easy to use, can realize wireless intercom and fixed telephone system interconnection;

4. System network architecture

This system is a set of all-digital convergence communication system, the explosion-proof amplified speech station, office administrative telephone, PSTN network, handheld wireless intercom system into a system to achieve effective synergy of the various systems; the system transmission to the LAN as the core, the use of optoelectronic composite cables as a carrier to solve the problem of power supply and signal transmission, the group network is very flexible, there is a network can be accessed in a variety of equipment, equipment migration is also very convenient, the use of transceivers, ring switches, EPON and other technologies can be used to form a LAN, all the equipment in this system have IP addresses, support for WEB remote login management.
