Cross-regional IP interconnected 2 way radio system for large parks such as large enterprises, schools, and hospitals
2024-08-29
Large enterprises, schools, and hospitals usually have their own parks with multiple buildings. People from different departments and different functions are distributed in different buildings. Telephones have become a direct and effective means for people in the park to work together. However, traditional park telephone deployment solutions often face the following difficulties:
- The park is large, the distance between buildings is far, and the cost and construction period of cable connection are high;
- Some personnel move frequently in the park and often cannot receive desktop extension calls;
- It is impossible to connect to various business management systems of the enterprise (such as broadcasting/dispatching systems).
Demand Analysis
Based on the fact that a certain unit has two work teams that often have to go out for work, in order to meet the daily communication between the unit and the work teams and the emergency command needs within the unit and the work teams, a dedicated network command system is now planned to be built:
- Requirement 1: The relay stations of the unit and the two work teams must be interconnected to achieve independent terminal command in the three coverage areas;
- Requirement 2: The unit park deploys an IP communication system for daily office communication and dispatching, and realizes remote door opening, broadcasting and other functions;
- Requirement 3: Provide a one-button intercom function for special areas such as computer rooms, workshops, and duty rooms. When help is needed, different functional departments can call the command center for help through the terminal with one click.
Solution
Based on the information and requirements provided by the customer, combined with Etmy's many years of experience in designing and building 2 way radio systems, an IP interconnection system based on DMR digital radio intercom technology is built:
Based on the information and requirements provided by the customer, combined with Etmy's many years of experience in designing and building 2 way radio systems, an IP interconnection system based on DMR digital radio intercom technology is built:
ET-R98D digital relay station and IP interconnection controller (built-in Dandelion server) are deployed within the unit, and each team deploys ET-R30B portable relay station and Dandelion 4G router to achieve network interconnection, thereby achieving interconnection and intercommunication of each relay;
Set up 4 groups: all-call group, unit internal, operation team 1, and operation team 2, and set up three receiving groups to receive the unit and all-call group respectively. When calling the all-call group, the terminal will respond to the call within the coverage area. When calling the unit or each team, independent communication can be achieved;
When there is no public network, the base station automatically weakens to a single base station mode to meet the emergency command needs of the park unit and the operation team.
Solution Features
The system makes full use of the intelligent networking technology of Dandelion routers. It does not need to rely on public network IP. It only needs to access the Internet to build an IP-interconnected 2 way radio system to achieve wide coverage across regions.
The system adopts leading computer technology, information technology and communication technology at home and abroad, combined with advanced architecture and mainstream products of technological development to ensure efficient and stable operation of the system.
Each base station relies on conventional broadband network, 4G and other public network resources as link access, so that the operation team can flexibly and flexibly achieve real-time interconnection with the headquarters within the coverage of the 4G public network.
Application Value
ETMY's DMR digital 2 way radio command and dispatch system based on IP technology architecture integrates the interaction of various information media such as voice, image, data, and text messages. Through a set of platforms, multimedia comprehensive command and dispatch services such as voice dispatch, conference dispatch, broadcast dispatch, personnel positioning management, and message push are realized, meeting various application scenarios such as daily duty, emergency command, mobile law enforcement, and inspection, meeting the command center's construction requirements for equipment integration, flat command, and intelligent operation, and truly realizing the concept of "de-islanding" comprehensive command and dispatch.
