Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, the present invention includes two parts of a main controller module and a wireless communication module, namely:

[0044] The main controller module runs the EPA industrial Ethernet fieldbus communication protocol stack, and is responsible for processing protocol data and executing control functions. The main controller module consists of a microcontroller and a memory section such as diagram 2-1 As shown, the main controller module is the core circuit, which controls the normal operation of the entire system and the realization of various functions. This module is a hardware platform with the core of the microcontroller U1 (ARM9 product of ATMEL company - AT91RM9200 chip). Such as Figure 2-2 As shown, the storage part is composed of the first ~ second random access memory U2 ~ U3, and the flash memory U4, which are re...

Abstract

The invention comprises a main control module and a radio communication module. Wherein the main control module runs the EPA industrial Ethernet field bus communication protocol stack, and the radio communication module takes charge of the communication to the other radio field devices, provides seamless connection to Ethernet and through USB interface circuit connects to the main control module to commonly build the EPA control network.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a wireless embedded controller based on the factory automation (EPA, Ethernet for Plant Automation) industrial Ethernet field bus. Background technique [0002] At present, the field control system mainly adopts the distributed control system (DCS). DCS uses one or more control units to control multiple loops, and its control part is distributed to some control boards, and each control board has one or more loops. In the process of forming the DCS system, due to the influence of the defect of system closure in the early stage of the computer system, the products of each manufacturer formed their own systems, and the equipment of different manufacturers could not be interconnected together. This kind of dedicated network is difficult to achieve interchangeability. There are many difficulties in interoperating and forming a network system for wider information sharing. [0003] W...
