IRIS.tunnel

As is the case for any production process, mechanical tunneling is controlled by numerous information and data streams. 

The timely availability of current process data in intelligible format is a  prerequisite for the optimal control of the operating processes, thus contributing to risk minimization.

Since all essential functions of a tunneling machine are controlled electrohydraulically, these quantities can be measured. In general, about 200 to 300 tunneling datasets are generated within 10 seconds. In 24-hour operation, this results in 2 million readings per day. The amount of data that is generated by the measurements and the working face recordings is also enormous. 

IRIS.tunnel offers a comprehensive data management and analysis tool for this data. This allows TBM tunneling to be continuously adjusted and optimized to the prevailing geological conditions.

Feature Tour

 

Shift data

can easily be recorded by a simple user-interface. This reduces the daily paperwork of the site team.

Reporting

provides a large number of standardized report formats. Thus, the data can be summarized and presented within a short time on a daily, weekly or monthly basis. 

TBM process data analysis

enables continuous evaluation of tunnelling data during and after the TBM drive. Here, IRIS.tunnel provides a wide range of nearly real-time process data, geological values and measurement data that can be correlated to each other. 

Alarm functions

allow the specification of trigger values for any measurements recorded by IRIS. Alarm messages can be sent by email to IRIS users.

Visualization

is available for most data types including TBM sensors, alignment or navigation data. In addition, all reporting and evaluation can be easily modified or adjusted by the user.

Cutter tool management

enables the site to record tool changes with few mouse clicks. IRIS presents inventory lists, tools for cutter change optimization and for tool wear prognosis.

Mass balance

The IRIS Electronic Muck Control (EMC) records the slurry TBM feed and discharge. The mass and volume calculated from these measurements can be compared with the expected excavation volume. 

IRIS.tunnel standard functions can be adjusted or expanded to meet each construction site‚Äôs needs. Special advanced modules are available for segmental lining management, cutter wear, settlement evaluation or slurry plants.  ITC provides hand-tailored information systems for any type of tunnelling project.

IRIS.tunnel modules:

  • Shift data: These data can easily be recorded by a simple user-interface. This reduces the daily paperwork of the site team. IRIS provides powerful downtime analysis tools.
  • TBM process data analysis: This module enables the ongoing evaluation of tunnelling data during and after the TBM drive. IRIS.tunnel provides a wide range of nearly real-time process data, geological values and measurement data that can be correlated to each other. During construction, this data is permanently available to the user. Alarm trigger values can also be set.
  • Reporting: IRIS provides a large number of standardized report formats. Thus, the data can be summarized and presented within a short time on a daily, weekly or monthly basis.
  • Comprehensive Visualization is available for most data types including TBM sensors, alignment or navigation data. In addition, all reporting and evaluation graphs can be easily modified or adjusted by the user.
  • Consumption management: IRIS offers the option to record material consumption, deliverables etc and to evaluate the data versus time or tunnel length.
  • Segment management: The segment module offers an inventory of lining segments including categorization of damaged and repaired segments.
  • Cutter tool wear enables the site to record tool changes with few mouse clicks. IRIS offers inventory lists, tools for cutter change optimization and for tool wear prognosis.
  • Mass balance: The IRIS Electronic Muck Control (EMC) records the slurry TBM feed and pipe discharge. Mass and volume calculations from these measurements can be compared with the expected excavation volume.
  • Maintenance: IRIS can list maintenance periods for different parts of the TBM. Finalized, scheduled and over-due maintenance works are highlighted.
  • Web cam viewer: Overview of different web cameras.
  • Personnel management: This module lists staff resources and produces shift reports for different work types.
