Focus of Paper
• Automated Data Collection
Automated
Maintenance Data
Collection and
Preventive
Maintenance in
Automated Systems
– Where Automated Data Collection is
currently used in building systems.
– How Automated Data Collection can Improve
Preventive Maintenance.
– How Automated Data Collection can Improve

One Current Use (1)
• In Building Automation Systems
(BAS)
Automated
Maintenance Data
Collection and
Preventive
Maintenance in
Automated Systems
– A BAS uses automated data collection
to display data on computer monitors.
• Automated data collection has been used
in BAS systems sense the 1980’s.
• In a BAS data is display on monitors to
show status of building systems.
A BAS is primarily used to control
heating, ventilating and airconditioning systems
Can be integrated with other building
systems such as fire systems,
security and etc.

• Data collected in a BAS is not used for
preventive maintenance purposes.
• A BAS notifies maintenance when a
problem has already occurred not before.

Potential Use (1)
• Computerized Maintenance Management
Systems (CMMS)
– A CMMS is used to organize and
improve the performance of manual
maintenance programs (preventive
maintenance) by:
Scheduling employees
Issuing and tracking work orders
Scheduling preventive maintenance tasks
Storing tasks required for preventive
maintenance on each piece of equipment
• Tracking Inventory
• Etc.

Potential Use (2)
• Computerized Maintenance Management
Systems (CMMS) (cont.)
– Data collection in a CMMS is normally
accomplished manually.

Improve Preventive Maintenance (1)
• By Moving a CMMS from a Preventive to
a Predictive System.
– The transition is accomplished by building a
history of normal operating points of
equipment.
• Data collection through the use of
automated data collection devices can be
accurate, timely and inexpensive.
• Data is collected through the use of a
variety of transducers and sensors.
• The data helps detect anomalies in
equipment operation.

Improve Preventive Maintenance (2)
• By Moving a CMMS from a Preventive to
a Predictive System.
– The transition is accomplished by building a
history of normal operating points of
equipment (cont.).
• These anomalies are telltale signs of
equipment breakdowns.
• The anomalies allow advance
investigation prior to actual equipment
failure.
• This reduces the impact of possible
breakdown.

Improved Profitability
• Through the use of Automated Data
Collection an Organization can:

Collection and
Preventive
Maintenance in
Automated Systems
– Reduce Maintenance Cost
• By helping to predict equipment
failures prior to catastrophic failures.
• Reducing cost of having parts
delivered overnight.
• Reducing parts inventory
– Increase Uptime of Equipment.
• Predicting failures which allows
scheduled downtime without
disrupting production.
• Reducing failures by improving overall
maintenance on equipment.
