Abstract

The invention discloses a method for carrying out simulation system hardware control isolation by use of a dynamic link library. A universal code of a hardware control software is separated from a differential code, wherein the universal code is achieved as a host control program and the differential code is achieved as a slave dynamic library. The host control program can be reused in different hardware control systems without correction. The inferior dynamic library achieves operation related to specific hardware control technology, and is encapsulated as the dynamic library, so the host control program and the slave dynamic library are allowed to become high-cohesion and low-coupling codes. The host control program also provides a microsecond high-precision timing clock, thereby meeting almost all requirements on the clock by the simulation system hardware control. A problem of inaccuracy indication is often created since hardware devices are damaged caused by aging or long-term use. According to the invention, by introducing the external accuracy table technology, an objective of adjusting indication precision can be achieved by correcting the accuracy table file rather than software.

Description

technical field [0001] The invention relates to the technical field of simulation hardware control, in particular to a method for isolating specific hardware control applicable to a simulation system. Background technique [0002] In flight simulator simulation, power station simulation and other simulation systems including people in the loop, it will involve the manipulation of equipment by people and the reflection of simulation results by equipment. The collection, drive and communication transmission of equipment hardware have always been the key to realizing this kind of simulation. An important aspect of the system. Such a simulation system necessarily involves two types of programs: hardware programs and simulation programs. The hardware program is a program that realizes sampling and driving of the device hardware; the simulation program is a program that uses the sampling value of the hardware program to generate the device hardware driver value required by the ha...
