Application On The Hydraulic Measurement And Control System With Variable Speed Base On Configuration And PLC Technology

Hydraulic technology with variable speed as a new type of transmission mode, it can reduce the energy loss due to throttling governor, to improve the efficiency of the system, the motor stepless speed control, the system can be achieved with the development of inverter technology, speed accuracyhigher, more and more widely used in hydraulic systems. Governor system with variable speed there are some problems to make the technology to a wider range of applications, this paper presents the PLC technology, hydraulic control, detection technology and configuration of organic combine to achieve a hydraulic measurement and control system with variable speed parameters in real time monitoring and dynamic display.This article describes a hydraulic technology with variable speed research status, on the basis of the variable speed hydraulic transmission principle, according to system requirements, design the PLC as the core of the lower machine control unit, PC mach-ine as the host computer monitoring system. Hydraulic test rig with variable speed hardware design and software design of control systems, PLC and analog module sele-ction, PLC and PC communication settings, PLC and hydraulic test bed sensor with variable speed connectivity and data transmission design, PLC hydraulic system with vari-able speed switch and analog control, and control of the PLC ladder system in the GX Developer7.0software to write. In this paper, hydraulic system with variable speed config-uration screen design, the design of the various variables, including the variab-le type, size, alarm design, configuration screen rendering of various controls, the establish-ment of the configuration database, configuration, software programprepara-tion of open-loop control of hydraulic bench with variable speed. Hydraulic test rig with variable speed experiments, according to the analysis of experimental data, indicating that the monit-oring system to monitor the effect of hydraulic with variable speed test rig is good, reliable performance.Hydraulic system with variable speed based on PLC technology, stable operation, high degree of automation, control, configuration screen in real-time dynamic display the characteristics of the hydraulic system running status, the monitoring system has high accuracy and practicality for the changespeed of the hydraulic control system further provides a good platform. Based on needs, you can easily on the basis of this monitoring system extensions to accommodate a wider range of system requirements.
