The city and its Project• City: Sant Feliu de Llobregat

• Name of the Project: Skynet

• Project Area: Environment.

• Status of the project: Network

Up&Running with expected extensions

PurposeImplement 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.

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

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%

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.
