#ECEB SUBMETERING

Team Members

-Mike Lee (dcl3)

Our RFA is based on Prof. Schuh’s proposal for a 3-phase, 208V, 60Hz power meters that can be placed inside individual rooms for detailed power monitoring.

#PROBLEM
The ECEB is notably a net-zero energy facility, which is possible due to utilization of energy efficient methods such as the use of solar panels. We would like to be able to measure and share data collected from the energy generated by the solar panels in order to help track the efficiency and use of energy of the ECEB building. With regard to the ECEB submeter of previous semesters, we would like to improve upon the accuracy of the data recorded to yield more practical and useful results.

#SOLUTION
Our solution is to create power meters that can accurately measure power, voltage, and current of individual rooms within ECEB and be able to accurately get and store these data metrics as well as being able to display them to either an LCD or the TVs within the ECEB. We plan to improve upon many of the shortcomings the previous implementation faced.


#SOLUTION COMPONENTS
##Subsystem 1: Power System
This system is required for powering the IC's, microcontroller, and LCD along with any other components of our project.

Chargeable Battery (5 to 10V)
Linear Regulator (Buck Convertor) MC34063AP

##Subsystem 2: Sensor/Electricity measurements
This system will allow the received AC signals to be changed into DC digital signals that the microcontroller can interact with.

ADC converters for current and voltage MCP3008-I/P
Voltage Transformer
Voltage Divider Circuit
Voltage Pull Up
Current Transformer CTF-5RL-0400
Current Divider Circuit
Current Pull Up

##Subsystem 3: Storing Information
Our design intends to store information offline onto a SD card and onto an online server
Microcontroller to Display and data recording System:
ESP32 Microcontroller used to transmit recorded data offline to SD card and to online server.
SD card module to interface SD card and ESP32
SD card to store data on
A cost effective online server or database to store our data

##Subsystem 4: Visual display of our data
This system allows us to display our data onto a screen to display to the viewer.

Usbc to HDMI to display information on a TV
LCD screen to display data onto

#CRITERION FOR SUCCESS
Be able to store our data offline on to SD card along with the date and time
Be able to upload our data online every 15 minutes via wifi
Be able to display data and waveform on LCD or TV
Be able to measure Voltage, Current, Power, and other key data metrics (Power Factor, etc.)

# Problem

WRSC (World Robotic Sailing Championship) is an autonomous sailing competition that aims at stimulating the development of autonomous marine robotics. In order to make autonomous sailing more accessible, some scholars have created a generic educational design. However, these models utilize expensive and scarce autopilot systems such as the Pixhawk Flight controller.

# Solution

The goal of this project is to make an affordable, user- friendly RC sailboat that can be used as a means of learning autonomous sailing on a smaller scale. The Autonomous Sailboat will have dual mode capability, allowing the operator to switch from manual to autonomous mode where the boat will maintain its current compass heading. The boat will transmit its sensor data back to base where the operator can use it to better the autonomous mode capability and keep track of the boat’s position in the water. Amateur sailors will benefit from the “return to base” functionality provided by the autonomous system.

# Solution Components

## On-board

### Sensors

Pixhawk - Connect GPS and compass sensors to microcontroller that allows for a stable state system within the autonomous mode. A shaft decoder that serves as a wind vane sensor that we plan to attach to the head of the mast to detect wind direction and speed. A compass/accelerometer sensor and GPS to detect the position of the boat and direction of travel.

### Actuators

2 servos - one winch servo that controls the orientation of the mainsail and one that controls that orientation of the rudder

### Communication devices

5 channel 2.4 GHz receiver - A receiver that will be used to select autonomous or manual mode and will trigger orders when in manual mode.

5 channel 2.4 GHz transmitter - A transmitter that will have the ability to switch between autonomous and manual mode. It will also transfer servos movements when in manual mode.

### Power

LiPo battery

## Ground control

Microcontroller - A microcontroller that records sensor output and servo settings for radio control and autonomous modes. Software on microcontroller processes the sensor input and determines the optimum rudder and sail winch servo settings needed to maintain a prescribed course for the given wind direction.

# Criterion For Success

1. Implement dual mode capability

2. Boat can maintain a given compass heading after being switched to autonomous mode and incorporates a “return to base” feature that returns the sailboat back to its starting position

3. Boat can record and transmit servo, sensor, and position data back to base
