Real-Time Data Acquisition System (RTDAS) – Architecture, Working, Guidelines & Industrial Applications

A Real-Time Data Acquisition System (RTDAS) is an automated technology used to continuously collect, validate, and transmit environmental data—such as emissions, effluents, or air and water quality—from instruments like CEMS and OCEMS directly to pollution control authorities like the CPCB or SPCBs. It works by integrating analyzers, edge processors, data loggers, and communication gateways to deliver tamper-proof, real-time environmental data via secured GPRS, VPN, or internet channels. RTDAS ensures regulatory compliance, especially in sectors like power plants, chemical factories, refineries, STPs, and ETPs, where environmental impact must be constantly monitored and reported. As per CPCB guidelines, all major polluting industries and waste treatment facilities are required to install a compliant RTDAS that retains historical logs, pushes data without human intervention, and integrates through secure APIs. In academia, research, and urban planning, RTDAS aids in climate studies, pollution modeling, and sustainability assessments. Its benefits include accurate reporting, real-time alerts, remote access, and enhanced transparency, supporting both regulatory needs and environmental protection. Aaxis Nano provides complete RTDAS solutions—from data loggers, analyzers, and communication setup to cloud dashboards and CPCB integration—designed to meet industry-specific requirements with reliable installation, maintenance, and compliance support.

What Is RTDAS? – A Technical Explanation

The Real-Time Data Acquisition System serves as an automated gateway that collects live analytical data from industrial sensors or analyzers and sends it to a central monitoring portal.

RTDAS in Technical Terms:

  • Data Logger: Captures raw data from instruments
  • Edge Gateway: Processes, formats, and validates data
  • Communication Interface: Transmits data via GPRS/4G/VPN/Internet
  • Data Server or Cloud: Receives and stores data for real-time access and historical analysis

RTDAS enables remote environmental data management across facilities, reducing manual interventions and enhancing data integrity.

  • Encrypted API Push to CPCB
  • Local/Cloud server mirroring for internal audits

RTDAS & CPCB Guidelines: What You Must Know

As per CPCB’s directive, any industry falling under 17 category polluting industries, STPs, ETPs, or hazardous waste facilities must install a compliant RTDAS.

RTDAS Guidelines by CPCB:

  • Data must be streamed continuously without manual intervention
  • Historical logs must be retained for at least 90 days
  • Tamper-proof, real-time reporting required
  • Integration with CPCB’s online portal through secure APIs
  • Regular health status ping of analyzers and loggers is mandatory

Failure to implement RTDAS can result in legal action, closure notices, or environmental penalties.


Industrial Applications of RTDAS

RTDAS plays a critical role in numerous sectors where environmental compliance and process monitoring are essential.

Key Applications:

  • CEMS for stack emission data reporting
  • OCEMS for real-time wastewater discharge monitoring
  • Ambient Air Quality Monitoring (AAQM)
  • Water quality monitoring at STPs/ETPs
  • Boiler emissions, VOC control, and hazardous waste incineration

Industries That Use RTDAS:

  • Power Plants, Refineries, and Cement Plants
  • Pharma and Chemical Manufacturers
  • Municipal Water Treatment Plants
  • Automotive and Paint Facilities
  • Sugar, Textile, and Pulp & Paper Industries

Educational Use & Environmental Impact

RTDAS also finds applications in:

  • Academic Research: Universities use it for environmental studies and model validation.
  • Urban Planning: Helps governments plan air quality zones and effluent channels.
  • Disaster Mitigation: Early alerts for chemical spills or pollution breaches.
  • Sustainability Reporting: Critical tool for ESG and ISO14001 compliance.

Environmental Advantages:

  • Timely pollution tracking
  • Lower risk of unmonitored emissions
  • Public health and biodiversity protection
  • Promotes data-backed policymaking
