Deutsch-amerikanisches Projekt

Die Geschichte des Projektes seit 2014 und Bilder.

Projektbeschreibung

Das Projekt startet im März/April und endet dann im September. Ca. 16 Studierende von der Texas Tech University und 16 Studierende der Jade Hochschule arbeiten im Projekt zusammen. Nach der Vorbereitungszeit März bis Juni setzt die gemischte deutsch-amerikanische Gruppe im Juli/August 6 Wochen an der Jade Hochschule die Arbeit zusammen im Projekt fort. Nach der vorbereitenden Theorie und Konzeption des Projektes arbeiten sie am Beispiel eines smart house models in internationalen Gruppen von 3-6 Studierenden an Teilprojekten, in denen sie spezielle Aufgaben planen, realisieren, programmieren und dokumentieren.

Detailierte Teilprojektbeschreibungen. Nur in Englisch verfügbar.

Group A - Heating Pool
Control the water temperature in the outdoor pool. Different power controllers and controller strategies are to be tested. For state‐of‐the‐art controls, operation should also be possible via mobile phone.

Plan of procedures:
subgroup 1:

• measure the step function response of the control process (without the module of subgroup 2)
• build the mathematical model from the step function response
• simulate (Scilab, Xcos) the control process with the mathematical model

subgroup 2:

• analyse an existing phase controlled modulator for the pool heating
• simulate the circuit with LT‐Spice
• test the existing hardware
• analyse an pulse packet controller for the pool heating
• simulate the circuit with LT‐Spice
• test the existing hardware

Both

• control unit design (with the math. model and the frequency response characteristic)
• simulation of the overall system
• programming the controller with Arduino
• measure the step function response of the overall system and make the presentation and a movie
• create the mathematical model with physical knowledge and compare it with that of measurement
• calculate the frequency response characteristic from the step function response
• simulate (Scilab, Xcos) the control process with the mathematical model and the frequency response characteristic
• create the presentation and documentation and make a movie

Group B: App Development
Combine all values gathered by other groups via MQTT in an Unity Application. This Application should also be capable of sending values to other groups.

Plan of procedures:

• Draw a possible interface consisting of User Interface components (2D)
• Develop possible scenes, keep them as generic as possible
• Research a suitable MQTT Library

subgroup 1:

• Build interface for 2 other groups (Elevator and Object Detection / Movement)
• ask them for possible in‐ and outputs
• Add word recognition

subgroup 2:

• Build interface for 2 other groups (Pool Heating and Photovoltaic)
• ask them for possible in‐ and outputs
• Build an interface which is able to display developments over time

Both

• split source code in reusable functions
• document source code
• document use cases and program in one (or more) Flowcharts
• create the presentation and documentation and make a movie

Group C: Elevator
Control the external elevator attached to the house.

Plan of procedures:

• Research on different elevator dispatch mechanism
• Summarize possible sequences
• Control the motor using an Arduino
• Use Sensors to locate the elevator
• Add security features
• Broadcast values via MQTT
• Add buttons and displays
• document source code
• document use cases and program in one (or more) Flowcharts
• create the presentation and documentation and make a movie

Group D: Photovoltaics
Supply the house with renewable energy by a PV system. The renewable energy system should consist of the solar module, an accumulator and a controller, which also contains an mpp‐tracker. For state‐of‐the‐art controls, operation should also be possible via mobile phone.

Plan of procedures:

• plan the energy supply of the house model – energy independent / grid independent
• create an energy supply with "normal" components: PV panel, battery, ..
• measure the characteristic curves I(U) and P(U) of the PV panels
• dimension the battery
• create a concept of a mpp‐controller

subgroup 1:

• analyse the existing control hardware and the existing mpp tracker with LT‐Spice and test it

subgroup 2:

• develop the software for the Arduino
• test the software with the simulation of the PV‐panel

Both

• join the hardware and the software
• test the whole system, draw characteristic curves
• create the presentation and documentation and make a movie

Group E: Optical Movement and Shape Recognition
Signal, if a special car as ambulance or fire truck enters the estate of the house. For state‐of‐the‐art controls, operation should also be possible via mobile phone.

Group E1: Signal, if any person or animal is in the garden or at the entry door, if nobody is at home.
Group E2: Signal, if a special car as ambulance or fire truck enters the estate of the house.
For state‐of‐the‐art controls, operation should also be possible via mobile phone.

Plan of procedures

• configure a Raspberry Pi 3 including a camera
• getting started with Python
• analyse the data from of camera (picture format, compression, origin, ...)
• adjust the resolution by your own procedure and find the optimal value
• practise image processing: colour reduction to grey/b‐w
• practise image processing: rotate, translate, mirror, scale, edge detection (if time)
• handle the effect of changing the intensity of illumination ‐ offset reduction
• if necessary: filter methods

subgroup 1 Optical Movement Recognition:

• empirical approach
• correlation approach
• difference method

subgroup 2 Optical Shape Recognition:

• practise picture segmentation = thresholding
• edge and corner detection such as Canny Edge Detection, Moravec’s Corner Detector
• AND/OR edge and corner detection such as Sobel Edge Detection, Harris Corner Detector
• Hough‐Transformation for a straight line

Both

• compare and discuss your results of both groups
• document used methods and program
• create the presentation and documentation and make a movie

Die Exkursion dient auch zum Kennenlernen der Partnerhochschule, um eine Entscheidung für ein späteres Studium dort besser fällen zu können.

Firmenbesuche (Lubbock, Dallas, New York) und Besuche von kulturellen Einrichtungen und Veranstaltungen während der Exkursion runden das internationale Projekt mit erweiterten Kenntnissen in der internationalen Projektbearbeitung und dem Kennenlernen der USA ab.

Ein abschließender englischsprachiger Exkursionsbericht wird von den Studierenden gemeinsam erstellt und dem Präsidium der Jade Hochschule zur Verfügung gestellt. Der Exkursionsbericht wird auf den Webseiten der Jade Hochschule in geeigneter Form veröffentlicht.
