Black box system used for recording and managing heat treatment industrial furnace process

Abstract

The invention relates to a black box system used for recording and managing a heat treatment industrial furnace process. The black box system comprises an intelligent central processing unit, a communication interface module, a video acquisition and management module, a data redundant backup module and a data query and retrieval module, wherein a real-time data acquisition module, a data encryption and decoding module, a data output module, an alarm module and an embedded HTTP / TCP (hyper text transport protocol / transmission control protocol) server are inlaid in the intelligent central processing unit; the communication interface module is connected with instruments and a PLC of site industrial furnace equipment to collect data of the instruments and write back to internal buffer area of the PLC to be called by the PLC; and data coming from other modules and units is subjected to real-time processing by the embedded HTTP / TCP server. By utilizing the black box system, operating state of an industrial furnace is continuously monitored, various process parameters and alarm, violation and misoperation behaviors are recorded in real time, the working condition and the safety parameter are inquired at any time, and postmortem analysis data is provided for possible safety accidents.

Description

technical field [0001] The invention relates to a heat treatment equipment monitoring system, in particular to a black box system for real-time collection, recording, query and analysis of industrial furnace process data. Background technique [0002] The basic mode of modern industrial furnace control is: PLC (programmable logic controller) + human-machine interface (touch screen), which can only provide simple process input and simple alarm prompt function, and cannot perform real-time operation and operation of equipment. and long-term records, and it is impossible to record the behavior of operators in real time. Once a process failure, equipment failure or operation error occurs, it will not be able to trace back to the state of the process equipment at the time of the failure, and it will not be possible to provide information for the process and equipment that have occurred. Equipment security incidents provide safe and reliable post-event analysis data, and it is imp...
