Digital Speed ​​Controller and Its Method for Controlling Engine Work

Abstract

The invention discloses a digital speed regulating controller and a method for controlling the operation of an engine. The digital speed control controller includes a first control unit, a first speed or frequency input conditioning unit, an actuator drive unit, a switch contact input unit and a host computer; the first speed or frequency input conditioning unit communicates with the first isolator A control unit is communicatively connected; the input end of the actuator drive unit is communicatively connected with the first control unit through the second isolator; the output end of the switch contact input unit is communicatively connected with the first control unit through the third isolator; the host computer communicates with the first control unit through at least one The communication interface communicates with the first control unit. The port of the communication interface connected to the first control unit includes a communication output and a communication input. The communication output of the port of the communication interface connected to the first control unit is connected to the first control unit through a switch. Realize the effect of controlling the engine with high safety and high reliability.

Description

Technical field [0001] Embodiments relate to methods engine control technology, and particularly relates to a digital speed controller and controls operation of the engine according to the present invention. Background technique [0002] With the diesel engine used in nuclear power plants continue to mature nuclear power plant emergency generator technology to meet the digital speed controller nuclear power emergency generators control function and performance requirements is particularly important. [0003] Prior art digital speed controller controls only meet ordinary diesel engine, having a low reliability and safety issues. And the hardware in the prior art digital speed controller does not satisfy the IEC 60987 standards, and the software does not meet IEC60880 standards. Digital controller chip speed has not identified by test, the V & V software certification and seismic test. Inventive content [0004] The present invention provides a digital speed controller and method ...
