Real-time monitoring method and system based on MODBUS_TCP

Abstract

The invention discloses a real-time monitoring method and system based on MODBUS_TCP. The method comprises the steps of reading an alarm signal from a PLC device connected with a station through an industrial Ethernet protocol (MODBUS_TCP protocol) when an operator starts to carry out the error-proofing verification or triggers the error-proofing alarm in normal work; extracting engine information in the alarm signal, and sending the engine information to a preset database to be stored; and reading the error-proofing data from the preset database, and displaying the error-proofing data on a client. According to the technical scheme, paperless automatic data acquisition can be realized, and basic level managers can quickly position the problem conveniently.

Description

Technical field [0001] The present invention relates to the field of automotive engine manufacturing techniques, and more particularly to a real-time monitoring method and system based on Modbus_TCP. Background technique [0002] Each station on the engine production line is equipped with a corresponding anti-wrong verification process, which requires a large number of anti-wrong verification forms to ensure safe and reliable production process. However, the current mainly validity verification is carried out by manually filling out the form and the grassroots management randomly illumination. There is low efficiency, a lot of waste of paper, not high accuracy, can not really reflect whether the problem of preventing error verification is executed And, when the error function is invalid, a station employee is required to initiate the report to know that there is a quality risk; or when the anti-wrong function is frequent, the manual method will cause data not timely problems; or ...

AI Technical Summary

Problems solved by technology

However, at present, the effectiveness verification of error-proofing at the beginning of shifts is mainly done through manual filling of forms and random checks by grassroots managers. There are problems such as low efficiency, a lot of waste of paper, and low accuracy, which cannot truly reflect whether the error-proofing verification is implemented. ; and, when the error-proof function fails, the staff at the station need to actively report to know that there is a quality risk; or, when the error-proof function is triggered frequently, the manual method will cause the problem that the data is not timely; or, when the error-proof verification If there is no record for one engine, there will be problems that cannot be accurately traced
