Abstract

An embodiment of the invention provides a data acquisition system. The system comprises workshop equipment, an OPC server, an OPC client and an upper computer. The OPC server is used for receiving parameter information of the workshop equipment. The OPC client is used for receiving the parameter information from the OPC server and sending the parameter information to the upper computer. In the prior art, because communication protocols of the workshop equipment are different, the upper computer remotely collects data of each piece of workshop equipment and operation is complex. In the invention, the above problems are solved; even if each piece of workshop equipment supports the different communication protocols, a field bus can be high-efficiently unified; and complexity of repeatedly developing a driving program is avoided.

Description

technical field [0001] The invention relates to the technical field of equipment information monitoring systems, in particular to a data acquisition system. Background technique [0002] At present, most sheet metal stamping workshops use equipment that supports Modbus protocol (a communication protocol applied to electronic controllers) or Profibus protocol (communication for equipment-level control systems and distributed I / O), including CNC punching machines , stamping manipulator, upper computer (touch screen or PC) and other auxiliary equipment. However, some sheet metal stamping workshops have equipment provided by different manufacturers at the same time, such as figure 1 As shown, the stamping manipulator of the Profibus protocol on the stamping production line needs to add an additional protocol conversion device, so that it can be unified into the Modbus field bus and collect data to the host computer. Considering the dot-strip line, a production line may spend t...
