Problems solved by technology

[0002] Before the present invention, the electric actuator control system generally used simple analog signal control, based on PLC or simple single-chip microcomputer control, there were backward control methods, low reliability, lack of perfect protection and fault alarm measures, and necessary Problems such as remote communication methods make the existing electric actuator system inconvenient for debugging and maintenance, and cannot perform on-site adjustment of parameters according to actual production conditions, and cannot form a network for remote control
[0003] The traditional electric actuator control system is not only poor in anti-interference, but also has a single function, which is not conducive to the expansion of system functions; at the same time, the control accuracy is also poor, and it cannot be used in the current application requirements that require higher and higher precision.

Abstract

The invention provides a full-digital intelligent control system for an electric actuating mechanism, belonging to the technical fields of intelligent instruments and meters and motion control. The control system is mainly used as a core component for the electric actuating mechanism to realize control functions, and the electric actuating mechanism using the control system can be used for controlling valves, strobes, air doors and correlative fluid equipment. The control system is provided with a power module which converts a 380 VAC or 220 VAC source of power supply into an internal power source for a controller; phase sequence, temperature, torque and position detection modules detect the running state of the electric actuating mechanism and alarm; after a 32-bit main control chip receives detected data, a control signal is outputted after calculation so as to drive a motor drive module, thereby realizing the purpose of controlling the action of an electric motor; the control system is provided with a man-machine interface, and provides an interactive interface for a field operator and the controller; the remote communication interface of the control system provides multiple interfaces so that information can be exchanged with a remote system; and the control system adopts the low-cost 32-bit chip as a core control chip, the in-built software thereof realizes all the control functions of the system, and the software of the system adopts a time polling system and is divided into a three-layer structure including a driving layer, a middle layer and an application layer. By adopting the design approach of hardware modularity and software structuralization, the invention simplifies the application flow of the control system in different electric actuating mechanisms; and by adopting the low-cost 32-bit chip, the invention greatly reduces the cost and improves the performance.

Description

technical field [0001] The invention relates to an all-digital intelligent electric actuator control system, in particular to a control system for an intelligent electric actuator, and belongs to the technical field of intelligent instrumentation and motion control. Background technique [0002] Before the present invention, the electric actuator control system generally used simple analog signal control, based on PLC or simple single-chip microcomputer control, there were backward control methods, low reliability, lack of perfect protection and fault alarm measures, and necessary Problems such as remote communication methods and other problems make the existing electric actuator system inconvenient for debugging and maintenance, and cannot perform on-site adjustment of parameters according to actual production conditions, and cannot form a network for remote control. [0003] The traditional electric actuator control system is not only poor in anti-interference, but also ha...
