Abstract
The invention discloses an online monitoring and maintaining system for plastic extrusion units. The system comprises a monitoring module, a router and a human-computer interface module, wherein the monitoring module is used for obtaining the online process parameters of the plastic extruders; the router is used for transmitting the online process parameters of the plastic extruders to the human-computer interface module through a wired communication manner; the human-computer interface module is used for encapsulating the data transmitted by the router, displaying the de-encapsulated data and transmitting the changed process parameters to the monitoring module through the router. According to the online monitoring and maintaining system, the equipment operation and maintenance personnel can know the production line status of the modified plastic extruders at the sites or in control rooms in real time and carry out real-time adjustment and maintenance on the production process and the like through the human-computer interface module to ensure the product quality.
Description
Technical field
The present invention relates to the information monitoring field, be specifically related to extrude unit on-line monitoring maintenance system.
Background technology
When extruding machine was worked, technological parameter had temperature and pressure, the temperature of head and the power that pressure, extruder kinematic train and heating system consume etc. of screw speed, each section machine barrel.Each technological parameter be monitored and be controlled to these technological parameters therefore need within the limits prescribed at any time to the Quality and yield important of product.
At present, the plastic extrusion machine observe and control system is mainly by the measurement and control of temperature module, pressure testing and controlling device, variable-frequence governor etc.Above each parameter measurement module is relatively independent measuring circuit, does not possess network communication ability, historical data archiving and Report Server Management ability etc. between each loop.The parameters value is read at the scene by the operator and makes corresponding adjusting control according to data, but does not have the record of data.This mode of production is feasible under specific time, specific condition and specific technological requirement, but obviously has limitation, and operator's skills involved in the labour and working site experience had very high requirement.Simultaneously, owing to there not being the historical data of extruder state parameter, when system breaks down or the product produced when quality problems occurring, the system manager can't carry out fault analysis and quality analysis with regard to the fastidious problem root of having no way of.These are all given in the management and have brought very large inconvenience, have not only increased the operation element amount, and the qualification rate of the stability of whole production line, reliability, throughput rate and product does not all have well to ensure.
Summary of the invention
The invention provides a kind of on-line monitoring maintenance system of plastic extrusion unit, drawback for present extruding machine TT﹠C system, from economy and point of view of practicability, need technician's field maintemance, Real Time Monitoring in the production run to solve, without production process data record, problem that production efficiency is low.
Purpose of the present invention adopts following technical scheme to realize.
A kind of on-line monitoring maintenance system of plastic extrusion unit comprises monitoring module, router and human-computer interface module; Monitoring module interconnects by router and human-computer interface module; Described monitoring module is measured the online technological parameter of plastic extruder, and data communication device is crossed router is delivered to human-computer interface module; Described human-computer interface module is transmitted the data decapsulation that comes, the data after the described decapsulation of demonstration with router, and the technological parameter of change is passed to monitoring module by router.
Described monitoring module comprises monitoring temperature subsystem, pressure monitor subsystem and frequency monitoring subsystem; Described monitoring temperature subsystem is measured each heating region temperature information of plastic extruder; Described pressure monitor subsystem is measured plastic extruder melt pressure information; The frequency monitoring subsystem is measured plastic extruder speed-frequency information.
Described human-computer interface module comprises device controller subsystem, Monitoring and Controlling subsystem; The device controller subsystem is used for temperature, pressure, the speed-frequency of control plastic extruder; Temperature variation, the pressure that the Monitoring and Controlling subsystem is used for the record plastic extruder changes, speed-frequency changes.
Every plastic extruder all is connected with independently monitoring module, and described independently monitoring module all is connected with described router.
The present invention is comprised of field apparatus monitoring modular, execute-in-place terminal and/or operated from a distance terminal take computer communication technology as the basis.The equipment operating maintainer can be at the scene or the pulpit understand in real time plastic extrusion machine production line situation, and by human-computer interface module production technology etc. is carried out real-time adjustment and maintenance, guarantee product quality.Utilize embedded technology, serial communication technology and field bus technique to develop novel extruding machine monitoring system, outside present each state parameter monitoring module, newly increase the module with serial line interface, utilize fieldbus to carry out networking these modules.Allow the complete working condition of clearly understanding on every production line of slip-stick artist, production line is realized Real Time Monitoring.
State parameter when the present invention also works to extruder system is monitored, when surpassing the scope of technological parameter defined, it sends warning, being conducive to like this operating personnel in time takes measures, fault alarm was shortened dramatically to the time of fixing a breakdown, thereby greatly economize on resources and cost, strictly avoid dispatching from the factory of substandard product, thereby improved quality and the production efficiency of product, strengthened the competitiveness of product in market.Simultaneously, system status parameters is carried out data storage management and history report, the researchist can call at any time these historical datas product is carried out quality analysis, judge which plastic product is qualified, which product is defective, and can review its problem reason to substandard product, improve or plastic formula such as is improved at the related measure thereby take measures technique is correlated with.And when system breaks down, can also review the concrete time of its fault, and implementing specific works personnel's responsibility, so just can exercise supervision to the staff, strengthen their sense of duty, thereby greatly improved the scientific level of system management.
This type of technology has versatility in various plastic extrusion machining production lines, extendability flexibly, is easy to change a little, just can be applied in the middle of other similar production line.The present invention has increased substantially the automatization level of modified plastics extruding production line, and the approach of simple and effective is provided for management, fault analysis and the product quality analysis etc. of system.
The on-line monitoring maintenance system of plastic extrusion unit of the present invention, from economy and point of view of practicability, can solve need technician's field maintemance, Real Time Monitoring in the production run, without production process data record, problem that production efficiency is low.
