Autonomous Meteorological Embedded Network for Fire

Fighting

Fan Zhang, Dmitry Stomakhin, Flavio Sira, Brian Hansen

Conceptual Summary

• Deployable device to collect data pertinent to fighting wild fires.– Wind Speed / Direction– Temperature– Humidity– GPS Location

• Wirelessly relay that data to fire fighting personnel.

Minimum Functionality

– Collect data from sensors in microprocessor on Sensor Node

– Transmit and receive sensor data between Sensor Node and Laptop Node

– Display received sensor data on an XP laptop via a C program

Maximum Functionality

– Push data into a database over the internet whenever an internet connection is detected on the laptop

– Google Maps interface for data pushed to database

– Multiple Sensor Nodes deployed in a mesh network for increased coverage range

Progress Summary

• Sensor and Base node end to end functionality achieved on development boards

• Sensor and Base Node schematics completed

• Initial board layout and milling completed

Status Report: Flavio

• Completed:– Drafted several documents– Created electric circuit for field node – Learned OrCAD schematic– Concentration on learning proper layout

• Need to do:– Final Board Layout and placement– Component placement on circuit board– Create poster for out project– Create and assemble the field enclosure

Status Report: Dmitry• Completed:

– All sensors can communicate with microcontroller.– Microcontroller can send and receive to/from laptop

node.– All timeouts, except compass, have been configured.– Output format between microcontroller and laptop has

been synchronized.• Need to do:

– Compass (I2C) ISR.– Clock sync between microcontroller and laptop node.– Get state of microcontroller.– Set reading intervals.

Status Report: Fan• Completed:

– Able to send/receive data from serial port – Able to receive data that is transmitted by

microcontroller through transceiver.– Able to converting raw data to readable format– Able to output data onto a simple GUI

• Need to do:– Output data onto a more user-friendly GUI– Save data onto a file– Show a graph of sensor data– Generate HTML code for sensor data table that can

be uploaded if internet is detected.

Status Report: Brian

• Completed:– Proof of concept code for some of the sensors– Base Node Schematic – Draft milling of Sensor Node– Team coordination / support

• Need to do:– Final Gerber to Milling machine conversion– Component placement on circuit board– Team coordination / support– Assembly into enclosure

Demonstration
