SYSTEM AND METHOD OF SAFETY MONITORING FOR EMBEDDED SYSTEMS

摘要

The safety and integrity of an embedded computer system is monitored using an independent safety monitoring module in communication with the main controller module via a serial connection to a safety monitoring module proxy in the main controller module. The main controller module is monitored through the use of alive-telegram exchanges and computational challenges. The safety monitoring module also receives temperature information and supply voltage information about the main controller module. The monitored information may be evaluated using a prognostic model constructed using a simulation of failure modes off line.
