Caltta Assists Shandong Police: Wireless Communication Support Capability Reaches New Heights
×
When production operations span dozens of plants,
When communication needs shift from "making calls" to "sensing,"
When safety and explosion-proof standards are non-negotiable every single second...
Chongqing Huafeng Chemical, the world's largest adipic acid producer, decided to redefine the operation of its park through a communication revolution.
This time, Caltta provided the solution.
With over 3,000 employees, numerous production workshops, and stringent explosion-proof standards...
Chongqing Huafeng Chemical's communication system faces immense challenges:
Communication coverage must be blind-spot-free, with a near-zero error tolerance;
Intercom command needs to traverse inside and outside the park without distance limitations;
Explosion-proof safety and smart operations must be simultaneously achieved;
Communication needs to not only "be understandable" but also "be visible" and "be manageable".
Traditional intercoms alone can no longer support future development.
They need a communication system designed specifically for intelligent production.
Caltta, using the "2+5" public-private integrated communication solution, built a new communication infrastructure for Huafeng Chemical:
Solid Private Network: Deployment of the DMR narrowband trunking system with a 400M exclusive frequency to cover every operational nook and cranny of the park;
Public Network Empowerment: Launch of the eChat public network trunking system to connect internal and external communication of the plant, ensuring uninterrupted operations;
Unified Dispatch: Interconnection between eChat and DMR trunking systems with eChat dispatch as the primary means, achieving unified dispatch of eChat/DMR terminals;
Smart Terminals: Flexible configuration of PH790Ex professional digital explosion-proof radios, NH970Ex 5G explosion-proof smart terminals, and G180pro eChat public network radios based on different job requirements;
Integrated Interconnection: Interconnection of eChat, DMR, and the plant's existing PSTN system, enabling communication among private network radios, public network radios, 5G smart terminals, and wired phones.
Safer Assurance
The 400M DMR narrowband private network achieves comprehensive coverage of the park, with 8 carrier-frequency trunking base stations meeting the park's "high-capacity" grouped call needs, providing stable around-the-clock intercoms, blind-spot-free signals, and uninterrupted communication.
More Efficient Communication
By integrating the DMR private network with the eChat public network, it meets the intercom communication needs between internal and external areas of the plant, achieving integrated communication of voice, positioning, images, and data.
More Intelligent Operations
The 5G explosion-proof smart terminal with the built-in eChat clustering APP achieves multimedia information and video return functions. It can be equipped with various production and management APPs, achieving mobile and intelligent operations like work permits and equipment inspections.
Faster Emergency Response
With the integration of public network, private network, and wired phone systems, emergency response chains are shorter and handling is more timely.
In the unseen flow of signals, a quiet yet far-reaching revolution is quietly taking place in every corner of the park.
Chongqing Huafeng Chemical has shown us through its actions: In the future industrial world, communication is not auxiliary; it is the productivity itself.
Caltta's "2+5" integrated communication solution, not only solves communication issues but also empowers safety, efficiency, and intelligence, making every operation dispatch, every emergency response faster, safer, and smarter.
In the future, Caltta will continue to use innovation as an engine, ensuring that every park has its own smart artery.
Smart connections, further advancement.
