To monitor the operation of embedded devices in harsh outdoor environment, this thesis designed an embedded E-mail advice software based on SMTP protocol. E-mail notification software is running on embedded devices with GPRS network, it first goes for the test to get the warning information and forms the E-mail's content and title in designed format, then establishes TCP link between the device and E-mail proxy Server through the GPRS network and sends the warning information to the E-mail proxy server according to the grammatical pattern of the SMTP. At last it designes a relative experiment to confirm the reliability of E-mail notification software. Tthe result of experiment shows that embedded E-mail advice software based on SMTP can meet the real operation's requirement and it has a relative reliability and stability.
