Problems solved by technology

[0002] At present, a large amount of measurement and control work is required in the field of industrial automation. The measurement signals are of various types (such as temperature, pressure, speed, displacement, etc.) and in different forms (such as continuous signals, discrete signals, switching signals, analog signals, digital signals, etc. ), the control methods also include various forms such as process control, logic control and motion control. Due to the rapid development of industrial automation technology, measurement and control devices are usually required to have a certain degree of flexibility to adapt to the changing needs of the environment. However, once the current measurement and control devices are developed After completion, its functions and performance are fixed, so it cannot meet this need

Abstract

The invention discloses a restructurable network measurement and control apparatus and a modularized programming method thereof. The apparatus comprises an embedded processor module, a field programmable gate array module and an industrial Ethernet module. The embedded processor module, the field programmable gate array module and the industrial Ethernet module are connected through a printed circuit board to form a measurement and control apparatus provided with a network communication capability. The measurement and control apparatus is provided with a real-time operation system, a Java runtime environment (JRE), and a network protocol stack adaptive to the industrial Ethernet module. The method involves utilizing an assembly programming development environment development assembly to form a modularized measurement and control program, converting the modularized measurement and control program into a Java program, scheduling a Java program integrated development environment to compile the Java program into a Java byte code, and sending the Java byte code to the measurement and control apparatus through an EtherCAT network. The measurement and control apparatus provided by the invention is provided with software and hardware restructurable capabilities.
