  4. 4. 4 VALUE PROPOSITIONS CHANNELS CUSTOMER RELATIONSHIPS CUSTOMER SEGMENTS KEY PARTNERS KEY RESOURCES KEY ACTIVITIES Cost efficient alternative to traditional smart metering, less money investment needed Time Local colleges. local developer Contracts / jobs as consultant, to implement a customer solution Time for development, developer skills, ability to create customer solutions Software development, finding customers, implementation of customer solutions Colleges with its people ( students, lecturers, professors ) and their projects ( this one! ) influcence local deciders ( local government, local city council, companies with facliities and plants) and influencers ( i.e. Governmental and municipal institutions ) Crowdfunding, Communication between the local colleges & local developers with their local authorities and customers 1. Local decision makes nd authorities ( local government, local city council, companies with facilites and plants ) 2. Govenmental and municipal institutions in 3rd. World countries and other low-price low-developed countries, 2. Non- governmental organisations (NGOs) 3. Local citizen societies,e.g. Citizen science allience
  5. 5. 5 2 Components 1/2 1. Embedded Device, to be plugged mechanically to the analog meter ( by magnetism, vaccum, electrical or optical interface... ), either permanently or temporary 2. Smart mobile device, e.g. a smartphone with built-in cam(s) and some electronic and wireless interfaces 3. Digitizer ( an electronic or optical interface, e.g. fieldbus bus, optocoupler, cam, scanner ) - part of (1) or (2) respectively 4. Tagger – part of (1),(2),(3),(6), (7) or (8) respecitively - , a data converter which converts the digital data ( e.g. an image taken by a cam ) to a "Tag" ( e.g. by optical character recognition ). A "Tag" is a date with minimal size ( e.g. a "data word" of 2 Bytes, not a 100 KBytes image ).
  6. 6. 6 2 Components 2/2 5. Interface to Device Manager and Configuration Manager, or own tools or adoptions of such tools. The management tools might be based surprisingly on advanced technologies and leading-edge tools like OpenStack, Chef / Puppet / Salt, Windows Desired State Configuration ( DCS ), FDT/DTM, PLCs with OPC UA, ... 6. Interface to Programmable Logic Control ( PLC ), Supervisory Control and Data Aquisition ( SCADA ), Distributed Control System ( DCS ), Manufacturing Execution System ( MES ), Laboratory Information Management System ( LIMS ), Enterprise Resource System ( ERP ) Facility Management System or any other PC- or Cloud based Energy Management System ( EMS ) for energy monitoring and energy data manageme 7. Interface to Cloud Services ( IBM BlueMax,... ) 8. Own implementations of Cloud Services ( at Heraku, AWS, Azure... )

  8. 8. 8 3 Signal Chain by Functions 2/5 1. Sensing • Digitizing ( e.g. analog/digital conversion, optical to digital conversion, image generation like by photography ) 2. Embeddded Processing • Pre-, final, post processing of data • Tagging – Reducing the size of a digitized data to a minimum ( e.g. getting a "data word" from an image, by optical character recognition ), which can then easily processed by other systems ( e.g. by an OPC server, a Data Logger, a Historian )
  9. 9. 9 3 Signal Chain by Functions 3/5 2. Embeddded Processing ( cont. ) • OCR - Optical character recognition • Character recognition by a pixel image ( e.g. by OpenCV ) • Vector based recognition 1.Create a pixel image file 2.Enhance contrast 3.Create character vectors from a pixel image, by quite simple self-developed ( embedded ) software – by detection, use and simulation of direction changes in the character vectors 4.Conversion of the vector data to the format of "Microsoft OneNote" 5.Vector based recognition by the free "Microsoft Ink Recognition Toolkit"
  10. 10. 10 3 Signal Chain by Functions 4/5 3. Connectivity • Serializing – Bi-directional conversion of binary data (e.g. jpg/png image ) to a serial object ( e.g in JSON, BSON, XML format ) • Creation, processing and transportation of serial data records ( e.g. in JSON, BSON, XML format ). Transfer of data records by a signal chain from source to destination, by protocols ( MQTT, CoAP, UDP, TCP, TinkerForge, wireless, ... ) • Synchronous and asynchronous data communications, contract- based communications, following the push and pull principle

  14. 14. 14 5 Scenarios 1/2 1. Connectivity 1. The embedded device is kept permanently at the analog meter. 2. Temporary data connections, when a device has access to a wireless network or the Internet, respectively. The devices may collect and keep the data of several analog meters, one-by-one. – The embedded device ( or the smart mobile device ) is just put temporarily at the analog meter, for communications, – And / or the embedded device ( or the smart mobile device ) later communicates to a docking station
  15. 15. 15 5 Scenarios 2/2 2. Data volume 1. Minimum data volume transfer ( data records with Tags or with character vectors ), to save time, energy, bandwidth 2. Sometimes you need to transfer high data volume ( e.g. a data record with an image,as reference, e.g. once a month, so that future data might be validated by the image, by humans ) In either cases the communciations between components has to be designed, that it either must be synchronous, or may be asynchronous. So a device with temporary connection to either a data source or data destionation, or to both, must be able to buffer the data
  16. 16. 16 6 Focus Principles ● "March separately, strike together" ( Helmut Graf von Moltke ) - Different teams of our project may each create different applications, by using different system platforms, different programming languages, different hardware, but with a common objective: Smart frugal metering! ● "Size matters" – The "Tagger" is important for our project, as it enables efficient data storage ● Data communications ● Synchronous and/or asynchronous ● Push and/or pull principles ● Contract-based
  17. 17. 17 6 Personal Objectives ● "Live long and prosper" – The project is about to achieve broad reputation ● The result of the project (data, code, documentation, physical prototype ) is a good reference, in case of job application as engineer or software developer ● The proof to have worked in an international project, beeing able to negociate and work together in distributed multi-cultural teams and organisations, is also a good reference, with any task done in the project ( not just engineering and software development, but also project management, quality management, product design, Web design, marketing, photography, accounting,.. ) ● Keep in mind: Your work is and will be unpaid, as there is no paying customer, no work contract, no startup company with a business model, no investors – you work for "yourself" in the project, it's up to you how much you contribute.
