Project background

The petrochemical industry is the basic and strategic industry of our national economy and social development, and its development and growth have been highly valued by the Party and the state。With the continuous expansion of the scale of petrochemical enterprises and the rapid development of technology，The construction of private network communication system in petrochemical enterprises is relatively lagging behind，Lack of communication means combining personnel management, safe production, safe communication, interconnection, unified command and dispatch, etc，It can not meet the needs of the digital development of petrochemical enterprises in the new era。

因此，Build a wireless communication system with rich functions, reliable performance and convenient deployment，It is widely used in the production, inspection, dispatching, fire protection, security, engineering and other departments of energy and chemical plants or oil and gas pipelines，In particular, it plays an important role in emergency rescue and fire rescue，It has become an indispensable means of communication in plant production scheduling and pipeline maintenance。

Demand pain point

At this stage, professional wireless communication in the refining and chemical plant generally adopts the walkie-talkie simplex direct or cross-frequency forwarding through the turntable, without forming a set of functional wireless communication system, and the following problems generally exist:

There are many signal blind areas and serious shielding

The petrochemical park area is large, the production area and the office area are separated, there are many tank devices in some outdoor areas and many closed Spaces in some indoor areas, resulting in many wireless signal coverage blind areas, serious signal shielding in the central control room, and outdoor operators cannot maintain smooth communication with the control center。

Personnel system is huge, management traceability is difficult

The petrochemical park has a large area and many inflammable and explosive areas, and personnel inspection paths and whether to enter and exit the explosion-proof areas often rely on the consciousness of employees, and there is no scientific management means。In the event of an accident or emergency, rapid feedback is not possible, the event processing time is low, and it is difficult to trace the source。

The call efficiency is low because the channel is not evenly busy

The existing park communication systems (analog or conventional intercom, fixed-line system, PA system) are independent of each other, the channel distribution is uneven, the channel can not be shared, and the call often appears call waiting, blocked and so on。Without authority management and priority distinction, the command center cannot achieve unified management and coordination in the first time in the event of an emergency, and lacks the ability of unified command and dispatch。

Traditional analog communication system has a single function

With the development of enterprise digitization and intelligent management, the original wireless communication system can only meet the simple voice communication requirements, and cannot provide digital recording, telephone scheduling and interworking, equipment monitoring, terminal management and other functions, which is difficult to meet the information management needs of modern large chemical enterprises。

Flammable and explosive environment, high explosion-proof level requirements

There are a lot of combustible gases in the refinery plant, and it is easy to produce a large amount of flammable dust in the production process, so the explosion-proof level of communication equipment is becoming higher and higher, according to the situation of different plants, high-risk and flammable areas require the use of IIB explosion-proof equipment。

solution

After careful field investigation, Beifeng Communication built a multi-carrier digital wireless communication solution with rich functions, high safety and wide coverage for the complex building structure and production environment needs of the petrochemical enterprise:

System topology

Outdoor communication coverage is completed through high-gain fiberglass antenna combined with digital communication system. Indoor multi-carrier frequency system is deployed for communication coverage in closed rooms, office areas, and dense canned areas to sweep communication blind areas from inside to outside to avoid signal interference.

According to the actual use needs, habits and the number of users of the intercom terminal in the plant area, the appropriate grouping mode is designed to group the number of the user departments, different workshops and shift groups, so as to determine the number of carrier frequencies in the cluster system, achieve dynamic channel allocation, and meet the daily and emergency communication needs in different fields.

The SDC intelligent scheduling system is built for personnel management and scheduling in the park, such as personnel command and scheduling, personnel positioning, patrol control, and visitor control。At the same time, the recording and broadcasting system and the Internet of Things patrol system are built to store all communication business data under the system, and can be played back according to a variety of query conditions, which is used for personnel control such as route monitoring and identification of inspection personnel, visitor management, and tour route monitoring.

Build an interworking gateway, realize the interconnection of analog/conventional direct intercom system, fixed phone system and PA system, help the central control room, dispatch room or the office leader to configure the dispatch desk, and realize rich functions such as PC voice call, forced disassembly, forced plug, monitoring, and traffic statistics;

According to the plant environment and the distribution of the number of people, the construction of IIB explosion-proof terminal is used for the daily communication of the staff of various departments in the petrochemical park。
