EECE 200 Project Proposal, Fall 2010

1 Green Office Team Number: 33 Nadim Hachem Karim Chehab Wajeb Saab Sabine Haddad Course: EECE 200 Friday, December 7th 2010 2 -Introduction:  Why are we doing this project? This project is being accomplished in order to be able to acquire the knowledge and experience needed in our engineering career. Moreover it represents a good percentage of our EECE 200 course; as such it will not be taken lightly and given the time and effort needed in order to obtain a good grade.  Problem Statement: We are going to build a green office that uses the Speedy 33 DSP board which will control multiple sensors in the office in order to achieve maximum power efficiency, thus making the office environment friendly.  Project Objectives: Controlling several functions in the house through different sensors: -Light sensors to control the intensity and mood. -Temperature sensor to control the water heater. -Motion sensor to control water pump.  Project Specifications: -The office should be controlled through the Speedy 33 and a remote site. -The doors should open and close automatically. 3 -The intensity of the external light should control the number of LEDs that are ON; the mood should control the color of working LEDs. -The water pump should turn on automatically when detecting motion. -The water heater should keep the water temperature within a constant range. -A seven segment display should display either the number of LEDs that is on or the amount of power consumed. -A remote site should display the status of the doors and control a special function. -The functionality of the remote site should be tested by an independent switch.  Constraints: -The project will be accomplished by the combined efforts of 4 students. -The SPEEDY-33 board is to be used in this project and kept hidden, as well as the wiring and cables. 4 Organization: Page -Grading Sheet 1 -Title Page 2 -Introduction 3 1.

The motor would be in charge of the automation of the door through a fixed axis. The status of the door (open/closed) should be displayed on the remote site. -The lights are controlled by sensors to save energy: if the sensor detects a light below a specified minimum value, 2 LEDs would be on. -If the sensor detects light above a maximum value, only one LED would be on an external switch would control the mood. for every mode correspond two moods that can be alternated according to the user's input. 6 -According to the light intensity, the motor controlling the curtains would be activated for a limited period of time by using a for loop and specifying the number of desired iterations in such a way to lower the curtains when the light is greater than a certain maximum value and raise them when it's lower than a minimum value. -The curtains should also be programmed in a way such that the curtains do not repeat the same operation twice successively (using embedded case structures). -A motion sensor should be placed directly under the water pump which should be activated when motion is detected. -The water heater would possibly be made of a combination of resistors in contact with conducting elements like a metallic container. The heating process would be operated according to the input of two sensors. One would be placed slightly above the desired temperature, another one slightly lower, such that the temperature of the water would be maintained within a range and the process would take enough time to rest the heater and conserve power while keeping the water hot enough. -The seven segment display has two functions. It can display the amount of power dissipated or the number of lit LEDs. A case structure on LABView would be used to alternate between these two functions according to the input of the switch. 7  Design discussion o In the display of power: The amount of power would be calculated by LABView (somehow). The problem consists of displaying different letters on the 7-segment display according to the input value. For example, H can be divided into 5 segments; in order to display the letter H, these 5 segments should be lit. A combination of case structures would allow us to specify the lit LEDs for each range of consumed power, thus displaying the corresponding letter. o In the display of lit LEDs: Each lit LED gives a Boolean value of 1. Adding these constants would always give the number of lit LEDs. Taking this value to a case structure would allow us to configure the lit segments in the 7-segment display according to that number. o Remote site operation: -Door sensor -A motion sensor can be placed near the door which would wirelessly trigger a LED attached to a screen indicating the status of the door by on/off Boolean mechanism. o SFC (special feature control): -A wirelessly transmitted signal should deactivate the light sensor and the mood switch. It should also trigger the different functions of the special feature. 8 -Three cell phones will act as the transmitters in the remote controller, and 1 other cell phone will be wired to the speedy. The receiving cell phone will be assigned 3 different ringtones of specific frequencies for each of the controlling phones. Each of the frequencies will activate a unique function. -Design Alternative: The only parts of the design which might pose some trouble would be the remote site operation as well as the special feature control: -To indicate the status of the door and see whether it is opened or not, we use a laser which is triggered by the door’s opening that gets reflected through several mirrors and hits the roof of the house, thus showing a dot when the door is open. -We can use a car's remote control as an alternative solution: when the door opens, it would trigger the remote which would get the motor running. The motor's activity would then be used to indicate that the door is open. When the door is closed, the remote would send no signal to the motor which would stay off. -The Special feature control can be triggered using Microsoft’s Kinect Motion sensing camera, which will alert the speedy to activate the crazy lights using full body gesture recognition built into the sensor itself, a swipe of the right arm to the left will activate a function, a swipe of the left arm to the right will activate another and holding both hands in the air will results in the activation of a third crazy lights functions. The sensor can also be adapted to open the door. 9 - Timeline Schedule Deadlines Meetings Proposal Report Friday December 10,2010 At 3:00 PM Monday December 6, 2010 From 7PM To 12AM Thursday December 9 From 9AM to 1 PM(DONE) Project Soft Demonstration Monday December 20. 2010 at 9:30PM Every Monday After 7PM, Thursday Between 9AM and 1PM and if needed Tuesday from 9AM to 1PM after Labs are over.
