Craig E. Steiner Advanced Vineyard Project "Remote environmental data collection and logging system" Back to full resume | PDF version of this page Overview An embedded device that operates independently in vineyards and periodically records current environmental information, stores the data, and subsequently connects to the Internet via a wireless GPRS modem to send the data to a central server for analysis and graphing. Approach Develop an embedded system capable of monitoring and archiving data from temperature, humidity, and a number of specialized sensors to determine stalk width of vines. Design a communication protocol capable of operating over a GPRS modem to link the remote embedded device to an Internet-based server. Implement a server component to operate on a Linux Red Hat 9.0 server to receive data from the remote embedded devices and to send them new configuration updates when they connect. Utilize a SQL database to permanently store the data collected by each of the remote embedded systems. Provide a website and web application to allow the administrator to manage and configure all of the remote embedded systems via the Internet. Include a presentation level on the website that allows the data stored in the database to be presented to the user in a flexible, graphical format. Technology The embedded platform is based on the Texas Instruments MSC1210 microcontroller. The GPRS modem used is a Sony-Ericsson GT48. The MSC1210 firmware is written in both SDCC 'C' and 8052 assembly language. The website and server component is written in PHP 4.3.6 and runs under Apache web server version 1.3. The database used is MySQL version 4.0.18. Craig Steiner's Role Sole system architect and developer. Wrote the 8052 microcontroller firmware that drives the remote embedded devices. Wrote the server component that receives data from the remote embedded devices. Developed the website and supporting web application. Designed the database schema and performs DBA on an ongoing basis. Provided substantial input regarding hardware design and parts selection.
