CERN-EDUSAFE Meeting 28/10/13

WP3 focuses on studying the scalability and adaptability potential of the hardware and the
software of the PSS module, the Control System (CS) and the Data Acquisition system (DAQ) for
other markets and different types of environment. Focus is also on the safety system
modularity and integration aspects.
It is divided into two parts.
1. This individual research project focuses on design and integration optimization of the PSS module which hosts the
communication module, the safety sensors and the local intelligence for data/video local treatment. It is an essential node
for propagating the data from the cameras and sensors to the control system and vice versa from the control system to the
HMDs. It is a key element to the success of the project. Additionally, a very challenging optimization is required at all
design levels (electronics miniaturization, power consumption, integration, interfaces, wireless HW) to produce a system
sufficiently powerful, highly reliable, with small size and weight, suitable to the workers in the most demanding
environments.
2. The CS and DAQ architecture and components hierarchy need to be designed and integrated to meet the stringent
requirements from the AR technology and the software implementation constraints. It needs to be adaptable and scalable
to various working environment (sea, space, large underground areas,..) and must easily accept various types of
detectors/sensors. Attention needs to be paid to maintain high speed communication rates and data exchange between
the supervised persons and supervisors. The control system will be developed through web-based methods, the data
registered to a proper data-base for easy access for off-line analysis, the calculated environmental radiation activation
maps compared and agree with the radiation data measured on the field. The preparation of radiation maps is an essential
activity and must be solid and well understood.

Qualitative and Quantitative Analyses
A hazard analysis, predesign or postdesign, can be designated as qualitative or
quantitative. A qualitative analysis is a nonmathematical review of all factors affecting
the safety of a product, system, operation, or person. It involves examination of the
actual design against a predetermined set of acceptability parameters. All possible
conditions and events and their consequences are considered to determine whether
they could cause or contribute to injury or damage. A quantitative analysis is a
mathematical measure of how well energy is controlled.
A qualitative hazards analyses are conducted in the following sequence:
1. Identify both design and operational primary hazards (i.e., sources of danger) that could generate injury, damage, loss of function. These
constitute the top-level events. All other factors contribute to or affect these top-level items.
2. Identify factors contributing to the top-level events. These are listed as they come to mind. The analyst lists everything that could have an
adverse effect on the product or system. The list can be developed from theoretical considerations of possible hazards, from results of past
failures of equipment, or from knowledge of problems with similar systems or subsystems.
3. Items on the preliminary list are rearranged according to the effects that they will produce. Generally, this rearrangement is done by
continuing the analysis down through additional cause and effect levels. In some instances, certain conditions or events may be included in
more than one area.
4. Any other events, which consideration indicates should be included are then added to the analysis.
5. Determine what action most practically will control the triggering mechanism considering time sequencing, severity, frequency, etc.


Qualitative and Quantitative Analyses
Quantitative Analyses: This type of analysis is a determination of how well hazards
are controlled in a system, subsystem, or event. In any case, quantitative safety
analysis must be based on a qualitative analysis. Numerical values are then applied. A
probability analysis may be accomplished in a number of ways depending on the
desired end result.
1. Probabilities may be derived from experience data on operations of similar systems, preliminary tests,
synthesized combination values, or extensions of all of these. The quantitative expression may include not only
the expected rate at which the hazard will cause accidents but also the severity of damage that could result, or
it may include both.
2. It is morally and legally unjustifiable to permit a hazard to exist unless appropriate effort is applied to
eliminate it, control it, or limit any damage that it possibly could produce.
3. Sometimes, data are valid only in special circumstances. Generalized probabilities will not serve well for
specific, localized areas.

4. Reliability is the probability of successful accomplishment of a mission within prescribed parameters over a
specific period of time.
5. Design deficiencies are rarely quantifiable and can be easily overlooked by a quantitative analysis.

Delay or other issues
• We don’t have any delay for current milestone and overall studies carried out in a
perfect way. In addition, Some points have been noted as a risk for future milestones.
These are:
Risk Description
ESR 5 has not yet start working on
D3.1

Possible Effects
The architecture of the DAQ
software and the interface to the
Control system will be delayed.

Prevention Actions
Possibility
We based on the DAQ system and Medium
protocols that were developed during the
WPSS project making some improvements
to overcome the issues that have been
faced.

Missing detail specifications for AR
system

The current PTU is not designed for
AR. The electronic design for new
PSS will be delayed because of
missing detail specification for AR
system.

We tried to design a very modular and Medium
open architecture in order to easily make
adaptions and changes considering the AR
in the future.
