Abstract

The invention discloses a processor device with the self-diagnosis function. The device on a circuit structure comprises a display module, a detection module, a power supply monitoring module, a key switch module, an insertion monitoring module and a groove number check module. Compared with a traditional processor device, the processor device with the self-diagnosis function, which is provided by the invention, has the advantages of low power consumption, no fan, real-time operation state display, unique bus communication mode, more self-diagnosis contents to the device and wide self-diagnosis coverage by adopting a double-port RAM (Random Access Memory) as a bus separation method, and the like. The device can be applied to the field of large-scale projects, such as a nuclear power plantand can ensure the high safety and the stability of the system.

Description

technical field [0001] The present invention is a processor with a self-diagnostic function designed for high security and stable operation of the system, specifically a processor that can implement power supply voltage, FLASH, memory, bus, power-on reset, manual reset and Watchdog reset self-diagnostic self-diagnostic function of the processor. It can be applied to large-scale engineering fields such as nuclear power plants, and can ensure high security and stability of the system. Background technique [0002] In recent years, with the rapid development of automation technology and computer technology, the application of highly reliable electronic components, sophisticated manufacturing technology, complete redundancy means, advanced self-diagnosis technology and advanced control theory has made DCS (Digital Control System) The control function of the main processor is upgraded from the original simple control to a new level, providing a powerful control method for implem...
