Simulator measurement and control system based on multi-point measurement compensation method

Abstract

The invention provides a simulator measurement and control system based on a multi-point measurement compensation method, and belongs to the field of simulator measurement and control. The invention analyzes the advantages and disadvantages of an existing maintenance simulator measurement and control system, adopts the advantages and problems of a PLC as a lower computer, provides a multi-point measurement compensation method by itself, and measures and controls analog quantity and the like through a double-host time-sharing measurement and control scheme. A PLC single-host measurement and control platform and a PLC double-host measurement and control platform are built, the single-host platform is used for testing the measurement and control speed of a PLC single host, and the double-hostplatform is used for increasing the measurement and control speed of the measurement and control system. Meanwhile, normalization processing of the input analog quantity is achieved through ladder diagram programming software. Through continuous improvement, double-host measurement and control are adopted on hardware, and meanwhile, a multithreading technology is adopted on software to be combined with double hosts, so that the measurement and control system is further optimized, resources of an upper computer CPU are fully utilized, the measurement and control speed and precision of the measurement and control system are remarkably improved, and the problem that the measurement and control speed of a PLC single host on analog quantity is low is solved.

Description

technical field [0001] The invention relates to the field of simulator measurement and control, in particular to a simulator measurement and control system based on a multi-point measurement compensation method. Background technique [0002] The maintenance simulator is used to simulate the working process of each system (airborne equipment) of the aircraft, so that the trainers are familiar with its operating rules, understand its working performance, and improve the maintenance ability of the trainers. The application of maintenance simulator can effectively improve the maintenance technical level of aviation equipment maintenance personnel, and is of great significance to reduce the maintenance cost of aviation equipment in the whole life cycle. [0003] At present, the measurement and control methods adopted by the locomotive simulator measurement and control system mainly include measurement and control card measurement and control, single-chip microcomputer measurement...
