A Simulator Measurement and Control System Based on Multi-point Measurement and Compensation Method

Abstract

The invention provides a simulator measurement and control system based on a multi-point measurement compensation method, which belongs to the field of simulator measurement and control. The invention analyzes the advantages and disadvantages of the existing maintenance simulator measurement and control system, the advantages and problems of using PLC as the lower computer, And put forward the multi-point measurement compensation method, through the dual-host time-sharing measurement and control scheme, to measure and control the analog quantity. The PLC single-host and dual-host measurement and control platforms have been built. The single-host platform is used to test the measurement and control speed of the PLC single-host, and the dual-host platform is used to improve the measurement and control speed of the measurement and control system. At the same time, the normalization of the input analog quantity is realized by using the ladder diagram programming software. Through continuous improvement, we adopt dual-host measurement and control in hardware, and at the same time use multi-thread technology combined with dual-host in software to further optimize the measurement and control system, make full use of the CPU resources of the upper computer, and significantly improve the measurement and control system. Measurement and control speed and accuracy , Solve the problem of slow measurement and control speed of analog quantity by PLC single host.

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...
