Control system of nuclear fuel loading and unloading machine

Abstract

The invention relates to a control system of a nuclear fuel loading and unloading machine, which is integrated and intelligently driven and controlled by a PLC. The control system comprises an operation console, a PLC touch screen, a PLC, a video monitor, a weighing system and a gripping apparatus system, wherein the PLC is applied to data acquisition, logic control, interlock protection, motion calculation and servo driving communication and control; operation buttons, display signal lamps and a data display instrument on the operation console are connected with the PLC; the PLC touch screen comprises a logic control unit and is connected with the PLC by virtue of a PROFIBUS; a video system is used for providing visual images of the position of fixed points; the weighing system is used for monitoring weight signals in real time and providing relatively complete weightlessness, overweight and scratch protection; the gripping apparatus system is used for lifting and releasing nuclear fuel; all the protection of systems is realized in the PLC and text type promoting alarms are provided. An overweight and weightlessness trend data analysis module is additionally arranged, so that error alarms and false alarms of the overweight and the weightlessness can be reduced.

Description

Technical field [0001] The present invention is a program control system, which involves a control system for nuclear fuel loading and unloading machines that integrates and intelligent -driven control through PLC. Background technique [0002] Nuclear fuel loading and unloading machine is a key device for nuclear power plant fuel operation and storage (PMC) system. It completes the installation, replacement and unloading of the reactor nuclear fuel component by cooperating with the fuel transfer device.The control system of nuclear fuel loading and unloading machine is the brain center of the loading and unloading machine. It must meet efficiency, flexibility, accuracy, safety and reliability. [0003] In existing technologies, the nuclear fuel loading control system is mainly imported, and there are fewer domestic independent research and development of loading and unloading control systems.However, the following problems are generally existed: the control system of the loading...

AI Technical Summary

Problems solved by technology

However, there are generally the following problems: the control system of the loading and unloading machine is bulky, the cabinet design of the whole machine is unreasonable, the disassembly and investment of the system are cumbersome, the operation accuracy of the cart and trolley is poor, and the lifting system often appears overweight and weightless.

The disadvantage of the existing technology is: there is no special super-weight and weightlessness module, and multiple loop interlocks are used to realize this function, and false alarms often occur

The efficiency of loading and unloading has been reduced, and at the same time, an observer post has been added
