HENTEK CAT Catalyst & Catalytic Converter Solutions

Technical Solutions – Remote Control + Cloud Service

Intelligent Emissions Management for Distributed Assets

Industrial emissions control systems – catalytic converters, SCR systems, DPF regeneration units, and baghouses – are often deployed at remote or distributed sites (pipelines, wellheads, mining operations, renewable energy storage, wastewater treatment plants, shipping vessels). On-site monitoring is costly, and unexpected downtime can trigger regulatory violations (excess emissions) and costly penalties. The **Remote Control + Cloud Service** solution enables real-time monitoring, predictive maintenance, and remote operation of aftertreatment systems via cellular (4G/5G), satellite, or industrial IoT networks. Fleet operators gain centralized visibility, automated compliance reporting, and condition-based maintenance – reducing field service costs by 30-50% and preventing unplanned downtime.

System Architecture Overview

Complete remote control + cloud service architecture:
On-site sensors → Edge controller (PLC/RTU) → Gateway (cellular/satellite/Ethernet) → Cloud platform (data ingestion/storage/analytics) → User dashboard (web/mobile) → Remote command (control actions)

Core Component 1: On-Site Sensors and Edge Controller

How it works: Sensors continuously monitor critical aftertreatment parameters. Edge controller aggregates data, executes local control logic, and transmits to the cloud.

Key sensors for aftertreatment monitoring: Temperature, Pressure, NOx, NH₃ slip, O₂, DEF level/quality, Flow rate, Catalyst bed temperature, Vibration, GPS location, Engine runtime.

Edge controller functions:

  • Data acquisition (100ms–1s sampling)
  • Local alarms (e.g., high DPF pressure drop)
  • Closed-loop control (DEF dosing, NOx feedback)
  • Data buffering (30+ days offline)
  • OBD fault code reading

Remote command execution

Core Component 2: Communication Gateway

How it works: Transmits data from edge controller to cloud using available networks.

Communication options:

  • Cellular (4G LTE/5G) – low-cost, real-time
  • Satellite (Iridium, Starlink) – global coverage, higher latency
  • LoRaWAN/Sigfox – low-power, periodic updates
  • Ethernet/fiber – highest bandwidth, reliable

Gateway features: Dual paths, encrypted transmission (TLS 1.2+, AES-256), VPN, remote configuration, geofencing.

Core Component 3: Cloud Platform (Data Ingestion and Storage)

How it works: Ingests streaming data, stores securely, available for analytics/visualization.

Platform architecture:

  • Message broker (MQTT, Kafka)
  • Time-series DB (InfluxDB, TimescaleDB, AWS Timestream)
  • Object storage (AWS S3, Azure Blob)
  • Stream processing engine (Flink, Spark)
  • API layer (REST/GraphQL)

Data retention:

  • High-resolution (1s): 30–90 days
  • Aggregated (1m–1h averages): 1–3 years
  • Compliance data: 5–10 years

Core Component 4: Analytics and Predictive Alerts

How it works: Machine learning models predict failures before occurrence.

Predictive maintenance models: DPF ash cleaning, SCR catalyst life, sensor drift detection, DEF consumption anomaly, RUL estimation.

Real-time alerting: Critical alerts via SMS, push, email. Escalation paths and alert suppression for known events.

Core Component 5: User Dashboard and Remote Control

How it works: Web/mobile dashboards provide real-time visibility and remote control.

Fleet view features: Map-based location, status indicators, key metrics, compliance status, alert severity.

Asset detail view features: Real-time trends, historical comparison, alarm history, digital twin, camera feed.

Remote control actions: Start DPF regeneration, adjust DEF dosing, engine derate, clear faults, initiate catalyst heating, export compliance reports. All actions logged and secured with two-factor authentication.

Core Component 6: Compliance Reporting

How it works: Automated regulatory reports from validated sensor data.

Report types: Daily, monthly, annual emissions reports. Exceedance notifications. Audit trails (5–10 years). Tamper-proof hashing for evidentiary quality.

Regulatory integration: EPA CEMS, EU IED templates, China GB APIs. Direct API submission to portals.
