IIoT Case Study

BACKGROUND & CHALLENGES

At tunnel construction sites, submersible pumps play a critical role in continuously removing groundwater and preventing flooding. If a pump stops operating and the issue is not detected quickly, construction teams can face costly downtime, equipment damage, safety risks, and schedule disruption. At scale, two challenges often limit success:

1) Manual inspection burden
Confirming pump operation traditionally required frequent on-site patrols. In many cases, inspections had to be performed daily, including nights, weekends, and holidays, creating high labor and transportation costs for construction teams.

2) Reliable monitoring in harsh tunnel environments
Tunnel construction sites can expose equipment to dust, moisture, vibration, temperature variation, and difficult RF conditions. A remote monitoring solution needs to collect data reliably while reducing the need for workers to physically inspect each pump.

Safie addressed the challenge of remote operational visibility through its video platform and alert features. Cassia Networks addressed industrial BLE connectivity with the Cassia X2000 Industrial Bluetooth Gateway, designed to bridge field-level sensor data to cloud applications in demanding industrial environments. Macnica contributed solution enablement, technical validation, and deployment support to help bring the solution into real construction environments.

 

SOLUTION

The solution combines Cassia’s industrial Bluetooth gateway infrastructure with BLE current sensors and Safie’s cloud platform, enabling construction teams to remotely monitor pump operation and move from scheduled patrols to condition-based response.

Cassia X2000 Industrial Bluetooth Gateway (Connectivity Backbone)

The Cassia X2000 is the core infrastructure element that enables reliable Bluetooth data collection from sensors deployed near submersible pumps and forwards that data to the cloud for monitoring, alerts, and operational decision-making.

Key Cassia differentiators

  • Long-Range Industrial Bluetooth Coverage – Helps collect BLE sensor data across difficult industrial environments and reduces the need for dense receiver infrastructure.
  • Rugged Industrial Design – Built for demanding deployments where dust, moisture, vibration, and temperature variation can affect standard equipment.
  • Reliable Data Aggregation – Acts as the bridge between field-level BLE sensors and cloud-based platform, helping maintain visibility into critical equipment status.
  • Remote Device Management – Supports easier deployment, maintenance, and troubleshooting when gateways are installed at distributed or hard-to-access sites.
  • Cloud Integration Flexibility – Sends collected sensor data to cloud platforms for dashboards, analytics, and alerts.
  • Scalable Architecture – Provides a foundation for expanding from individual pumps to additional equipment, sites, and industrial monitoring use cases.

BLE Current Sensors (Pump Operation Sensing)

BLE current sensors monitor whether each submersible pump is operating properly. The sensors provide field-level status data that can be collected wirelessly without requiring operators to manually check every pump as frequently.

Safie Cloud Platform (Remote Visibility & Alerts)

Cassia gateways transmit pump operation data to Safie’s cloud platform, where construction teams can view pump status, receive alerts, and respond when abnormal conditions are detected.

RESULTS AND BENEFITS

Deployed together, Cassia X2000 gateways, BLE current sensors, and Safie’s monitoring platform enable a scalable remote monitoring system suitable for tunnel construction and other industrial environments where equipment status needs to be monitored reliably.

Cassia + Safie Solution Benefits

  • Remote Monitoring – Operators can confirm pump operation without relying only on manual, scheduled inspections.
  • Reduced Manual Inspection Work – Fewer routine patrols can lower labor requirements and transportation costs.
  • Faster Abnormal Condition Detection – Alerts help teams identify pump issues sooner and respond before problems escalate.
  • Reduced Operational Risk – Earlier detection helps reduce the risk of flooding, equipment damage, construction delays, and site disruption.
  • Improved Worker Safety – Remote visibility reduces unnecessary site visits in harsh or difficult tunnel conditions.
  • Reliable Data Collection in Industrial Environments – Cassia’s industrial gateway design helps support stable BLE communications in challenging field conditions.
  • Scalable Foundation – The same architecture can expand to additional pumps, sites, and other industrial monitoring applications.

How Cassia Enables the Solution

  • Long-range industrial Bluetooth coverage for sensors deployed around pumps and construction equipment
