Embedded real-time control method and embedded real-time control device of diesel generating set

Abstract

The invention provides an embedded real-time control method and an embedded real-time control device of a diesel generating set. The real-time control method comprises the following steps: if a task running in a task running step finishes running normally, the procedure executes a waiting step and then returns to a ready registering step; if the task running in the task running step is interrupted, the task transfers to an interruption service state, thus the priority of the task is compared with the highest priority of the task in a ready registering module by a task scheduling module; if the priority of the task is high, the task is executed; or, the task with the highest priority in the ready registering module is executed, the procedure transfers to the task running step. The embedded real-time control method is high in reliability, strong in instantaneity and high in hardware utilization rate.

Description

technical field [0001] The present invention relates to real-time control of a diesel generator set, in particular, the present invention relates to a real-time control method and device for a diesel generator set. Background technique [0002] At present, the supply of traditional energy is facing a severe crisis, and the power shortage has penetrated into every industry. To this end, there has been a large amount of investment to develop new energy sources, for example, photovoltaic power generation. However, the efficiency of photovoltaic power generation is limited, and its cost remains high. In addition, the development of water energy resources has a huge impact on the ecological environment, and is also restricted by factors such as the continuous depletion of water resources. [0003] For many industries and occasions, especially for applications such as communication and medical industries with high reliability requirements and data centers, diesel power generatio...

Problems solved by technology

Although the control logic of this sequential execution control system is simple and easy to implement, its disadvantages are: (1) If one of the tasks needs to be processed for a long time, it will directly affect the execution of other links.

When the system is more complicated, the cycle period will be lengthened, not only the data collection and processing of the diesel generator set will not be timely, but also the man-machine interface will be unresponsive, and the remote data communication of the diesel generator set will sometimes lose data due to timeout (2) The realization of system functions based on this method relies on continuous loops, resulting in low execution efficiency, low utilization of microprocessor and other hardware resources, and reduced reliability; ( 3) When the system is complex, the real-time performance of this control method is very weak; (4) When the sequential execution system encounters strong interference, it will make the software frequently appear abnormal, make mistakes, run away, and even crash in severe cases situation, causing the operation of the diesel generator set to be seriously affected
