Pharmaceutical Plants & Cleanrooms Project Background

Pharmaceutical Plants & Cleanrooms
Project Background

Cleanrooms demand exceptionally high standards in environmental cleanliness, operational discipline, and emergency response efficiency. Traditional communication methods often fall short in supporting effective collaboration within sterile environments.

This solution is built on an IP network architecture, integrating dustproof embedded devices with zoned broadcasting capabilities. It enables contactless communication, emergency alarm triggering, and unified dispatch management within clean areas—ensuring process continuity and personnel safety.

Requirements Analysis

Adaptability to Sterile Environments:

Equipment must be embedded-mounted and dust-sealed to prevent contamination within the cleanroom environment.

Rapid Emergency Response:

Support one-touch alarm triggering, sub-second call setup, and zoned broadcast linkage for immediate incident response.

High-Definition Voice Quality:

Wideband audio encoding combined with echo cancellation technology ensures clear communication even in noisy environments.

System Compatibility:

Seamless integration with access control, surveillance, and fire alarm systems; supports SIP protocol for third-party connectivity.

Zoned Control:

Broadcast areas are divided according to cleanroom classification levels, enabling independent control of broadcast content.

Design References

This solution design strictly follows the current national standards and regulations, ensuring compliance throughout the
entire process from system design equipment selection, construction installation, to acceptance testing.
The main references include:

Cleanroom Standards:

ISO 14644-1 — International Standard for Cleanrooms and Associated Controlled Environments.
GB 50472-2008 — Design Code for Cleanroom Facilities in the Electronics Industry

Communication Standards:

IETF RFC 3261 — SIP v2.0 Protocol Specification.
G.168-2014 — Digital Network Echo Canceller Standard

Safety Standards:

GB 50116-2013 — Code for Design of Automatic Fire Alarm Systems.
GB 50057-2010 — Code for Design Protection of Structures Against Lightning

Solution Design and System Architecture

The cleanroom paging and intercom system is built upon an IP-based network architecture. Through the use of access switches and a core switch, it enables seamless interconnection among devices located in corridor areas (ceiling-mounted speakers, one-touch call stations, IP network amplifiers), cleanroom areas (emergency call stations), and the control room (duty phones, uninterruptible power supply, core switch, SIP dispatch server, etc.).

The SIP dispatch server acts as the central control unit, responsible for signaling processing and device registration management, ensuring stable and efficient voice communication. This IP network architecture not only facilitates system scalability and maintenance but also allows for effective integration with the enterprise’s existing IT infrastructure.

System features

Multi-Mode Communication
 
01

Multi-Mode Communication

 

One-Touch Call (Corridor Intercom Station): A metal push button triggers a dedicated number; the DSS key on the dispatch console flashes red and supports hands-free broadcast paging.
Emergency Dialing (Cleanroom Intercom Station): 12-key keypad enables direct extension dialing; supports 6-party video conferencing (H.264 1080P).
Broadcast Override: In case of a fire alarm, the amplifier automatically mutes background music and plays evacuation announcements (Signal-to-noise ratio ≥ 90dB).

02

Intelligent Interlocking

 

Expansion of linkage scenarios:
Temperature and humidity sensor exceeds the limit → play area alarm;
Equipment malfunction signal → automatic call to maintenance team.

Intelligent Interlocking
 
Visual management
 
03

Visual management

 

The duty phone is implemented through a 4.3-inch touch screen:
Real time monitoring of terminal online status (green normal/red offline);
Drag and drop partition broadcasting circle selection;
Alarm record retrospective (retained for ≥ 90 days).

04

Recording and Traceability

 

The server is equipped with a 250GB SSD, capable of storing ≥3 months of recordings, which can be searched and played back by time or device.
