Stamping workshop data acquisition system based on embedded Linux

Abstract

The invention provides a stamping workshop data acquisition system based on embedded Linux, including a core module, an extension module and an operation module, wherein the core module includes a microprocessor working circuit, a reset circuit, a storage management circuit and a JTAG debugging interface circuit that are connected; the extension module includes a switching value input and output interface circuit, a serial interface communication circuit, a USB interface circuit, an Ethernet interface circuit and an LCD display circuit that are connected; and the operation module builds an embedded QT operating environment with an embedded Linux operating system, and runs a QT application, wherein the operation module and the core module are configured to store data acquired by the extension module and complete the processing operation and uploading of data information.

Description

technical field [0001] The invention relates to an embedded Linux-based stamping workshop data acquisition system. Background technique [0002] The informatization of industrial production management is divided into two parts in the production management of stamping industrial enterprises, one is the production part, and the other is the business part. The former is managed by MES (Manufacturing Execution System), and the latter is managed by ERP (Management Information System). manage. Initially, the two systems worked independently of each other, creating silos of information. When enterprise managers try to eliminate this information gap, they often encounter a common problem: the lack of underlying technology support, which is not only reflected in the difficulty of extending the upper-level business planning process to the site, but also in the difficulty of transmitting the on-site execution data upwards . Due to this information gap, stamping companies have to ach...

Initially, the two systems worked independently of each other, creating silos of information

When enterprise managers try to eliminate this information gap, they often encounter a common problem: the lack of underlying technology support, which is not only reflected in the difficulty of extending the upper-level business planning process to the site, but also in the difficulty of transmitting the on-site execution data upwards

[0004] The disadvantages are also obvious. The types and specifications of the production equipment on site are not the same, and a large number of different data acquisition interfaces are required. The interface of the industrial computer itself is insufficient, so a lot of interface cards need to be expanded, which makes the cost higher and the compatibility is not available. ensure

The main control core of this solution is a single-chip microcomputer, with relatively few internal resources, it is difficult to embed into the operating system, and the adaptability to the industrial site is relatively poor; moreover, there are a lot of electromagnetic interference in the industrial site, once the program runs away, the entire system will be paralyzed, and the stability not tall

These controllers can meet the requirements of MES in some specific occasions, but due to their own structure or design limitations, they cannot meet the requirements of the executive manufacturing system in the stamping industry, which seriously restricts the general application of MES in the stamping industry
