This is a working session devoted to Open Sensor Platforms. The purpose of this Task Team is to get a solid knowledge about sensor platforms and share it with the world. OSP is a key element of an urban platform, and serves to make data from any city sensor available to all city applications. Shaped by Barcelona’s open source Sentilo platform, OSP Leaders from Barcelona will be joined by OSP pilot cities from Dubai and more.

4. Purpose
Implement an EXPERT SYSTEM to automate infrastructure management SmartCity
quickly and flexibly, with a generic tool, reusable in different scenarios.With the following
characteristics:
 Generic tool, reusable in different scenarios.
 Integrated multi-sensory platform: Sentilo, Fi-ware other.
 Portable devices embedded, such as Raspberry-pi, etc, allowing Skynet to be used used as
an integrator of sensors and actuators on the Sentilo’s platform.
 Programmable in a functional simple language which is easy to learn, but powerful
enough to implement complex algorithms of artificial intelligence, fuzzy logic, learning, etc.
 Programmable remotely through an interface HTTP / REST.
 Availability of Web tools, java and mobile to program expert system rules and interact
with him.

SKYNET – Project organization (Dependency diagram)

12. SKY language: general characteristics
 Very simple but powerfull functional language
 Based on S-Expressions (homoiconicity: data and code are represented in the
same way) => Rules that generate new rules!
 Easy parsing and code generation (Wizards can create rules easily)
 Small footprint (can be ported to devices with low resources)
 Easy to extent with new built-in functions
 Support for user defined functions
 User defined functions can be recursive
 Multi-threaded
 Just 5 basic data types: strings, numbers, booleans, references (symbols), lists
 All these data types are persistent

13. SKYNET - Case study.
Improving energy efficiency central building of City Hall
 Lighting control of the building depending on the presence and level of brightness.
 Control of air conditioners in meeting rooms depending on the programming of the
corporate agenda.
 Energy savings around 60%

14. SKYNET - Initial evaluations
 Demonstrated the viability of the tool and its possibilities.
Milestones achieved:
To automate the management of infrastructure SmartCity (with
Sentilo or directly accessing sensors) with a very low development
cost, so just put the effort in creating an expert system rules.
