Predictive Maintenance. Power consumption Monitoring Systems
Consider a series of vibration signals measured on different days on a theme park ride. Can you see the difference between the signals and determine:
• which signals signify that the ride is safe
• which signals signify that a part in the ride is starting to wear out
• which signals signify that a part is worn sufficiently to require replacement
• which signals signify that a part is worn sufficiently to endanger riders?

Predictive Maintenance Data Acquisition
Theme Park Power Consumption
Transformer Back-up generator Insulated cables
A transformer is an electrical device that transfers energy from one circuit to another by magnetic coupling with no moving parts
Back-up generators to use just in case the power goes out on any of the rides.
We would need insulated cables because of the theme park’s location
Theme Park Power Consumption
We have no exact value Should be anywhere from
20MWatts-100MWatts Cost would depend on the power

Monitoring of maintenance systems
One of the measures of quality of major theme parks is the degree of maintenance given to the attractions and rides
Good parks work hard to achieve short down times, and a safe experience in their attractions.
Measuring cost effectiveness of rides.
Networks have been used in one form or another in major theme parks since the 70's.
