Factory DMR digital wireless communication solution

Wireless intercom signal coverage system as the relevant functional departments of the daily operation scheduling and security of the wireless mobile communication platform, its most important demand is that the system to be able to solve the signal blind spot inside the large building, through the system so that the radio signal in the relevant area to be effectively covered, so that the user is no longer bound by the building space and shielding, to achieve work coordination and command and dispatch in the relevant area.

With the continuous development of social economy, people's demand for resources is increasing day by day, which makes the scale of the factory become larger and larger, the production management is more complex, the country and enterprises attach great importance to the production safety of large factories, and the construction of safe and reliable wireless intercom system is also listed as the top priority of all work.

 

Why do you need a wireless intercom system?

Wireless intercom signal coverage system as the relevant functional departments of the daily operation scheduling and security of the wireless mobile communication platform, its most important demand is that the system to be able to solve the signal blind spot inside the large building, through the system so that the radio signal in the relevant area to be effectively covered, so that the user is no longer bound by the building space and shielding, to achieve work coordination and command and dispatch in the relevant area.

Because most of the factories are large buildings, the shielding of reinforced concrete structures is more serious, especially some large underground buildings are often blind spots, so how to solve the indoor wireless coverage, meet the needs of users, and improve the network quality has become more and more important, and has also become a focus of wireless communication network optimization.

 

How to meet the communication needs of the factory?

The overall scheme adopts the intercom system base station heterogeneous frequency relay technology to expand the communication range of the walkie-talkie:

(1) When the communication between the walkie-talkies cannot be realized due to the distance or the building blockage, the base station can relay the walkie-talkie signal at different frequency, and then send the signal through the indoor antenna distribution system, thereby expanding the communication distance between the walkie-talkies;

(2) After the base station is adopted, the blocking and shielding caused by the building structure and environment to the wireless signal will be overcome, so that the signal will be distributed to the various working areas of the entire transfer station, play the role of relay communication, and achieve no blind spot in the communication in the transfer station.

 

Networking scheme

In the factory, the coverage mode of indoor omnidirectional antenna + RF coaxial cable is adopted, so that the coverage range of the indoor antenna as the end of the network is interlocking, and a large communication network is formed by multiple signal coverage cells, so as to ensure that the coverage in the plant is wide and the signal strength does not exceed the standard.

Broadly speaking, the problem of indoor wireless coverage is not only the improvement of indoor blind spots, but also the improvement of indoor wireless communication quality, network quality, and system capacity. Indoor wireless intercom communication brings the possibility of improving the efficiency of management of building functional departments, and is of great significance for responding to emergencies and improving work efficiency.
