Abstract
The utility model provides a historical parametric curve access system, a parametric curve collecting machine and a man-machine picture are added, a window control center is installed in the collecting machine, a parametric curve storage catalogue is made in the man-machine picture system; the man-machine picture is connected with the parametric curve collecting machine, the parametric curve collecting machine is connected with a PLC communication board via an Ethernet switch. The historical parametric curve access system in the utility model is advantaged by fully using the original system, realizing backups and query of data curves via adding few devices, not only saving a large amount of one-time investment, reducing maintenance cost, but also making operation easy, maintenance convenient, and effectiveness rapid, breaking time limit, and calling backup parametric curves in any period at any time.
Description
Technical field
The utility model belongs to computer realm, relates in particular to a kind of storage and reading system that is used for cold rolled continuous annealing stove history parameters curve,
Background technology
The dynamic that the control system in cold rolling mill continuous annealing furnace district is gathered data requires not high, but need carry out accurate recording to each technological parameter of stove district, so that the searching of the adjustment of process optimization and equipment failure.Adopt process data to analyze acquisition system both at home and abroad mostly data are gathered preservation, because this system equipment device complexity, and the cost height, maintenance cost is huge.In order to save cost and investment, setting up procedure data analysis acquisition system not in the automatic control system in the domestic cold rolling mill continuous annealing furnace district that has, therefore can only preserve 15 days content for the data and curves of man-machine interface collection, call 15 days data in the past as need and can't realize.And concerning some the steel plate of quality problems and plant issue occurred, because the overlong time of midfeather, the time had just surpassed more than 15 days when pinpointing the problems, and also just can't search manufacturing parameter at that time.In addition, when equipment goes wrong sometimes, also need the initial stage running status is compared, also can't realize naturally.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of simple in order to eliminate above-mentioned defective, and small investment, instant effect utilize former have ready conditions and equipment carries function, realize the access system that the historical data curve is backed up and inquires about.
For this reason, the utility model has been taked following solution:
A kind of history parameters curve access system, comprise that Ethernet switch and programmable logic controller are PLC, set up parametric line harvester and man-machine picture simultaneously, window control center is installed in harvester, establishment parametric line storing directory in man-machine picture system; Man-machine picture is connected on the parametric line harvester, and the parametric line harvester is connected with the communication board of PLC by Ethernet switch.
The beneficial effects of the utility model are:
Because the utility model mainly utilizes original system, under the situation of not use data analysis acquisition system, only need acquire seldom utensil and just can realize backup and inquiry the data curve, not only save a large amount of one-time investments, reduce maintenance cost, and operation easily, be convenient to safeguard, take effect rapidly, but the limitation of breakthrough time is called the backup parametric line of random time at any time; As long as hard disk is enough big, just not free storage restriction.
Description of drawings
Accompanying drawing is a history parameters curve access system structured flowchart.
Embodiment
By the utility model structured flowchart as seen, the utility model mainly is made up of Ethernet switch, PLC, parametric line harvester and man-machine picture.Utilize original Ethernet switch and continuous annealing furnace district PLC, set up simultaneously a computing machine as parametric line harvester and a display as man-machine picture.System of window control center is installed in harvester, configures link address, and in man-machine picture system establishment parametric line storing directory.The parametric line harvester is connected on the Ethernet switch, again Ethernet switch is connected with the communication board of PLC, simultaneously man-machine picture is connected with the parametric line harvester.The parametric line harvester links the desired data that collects, and is recorded in and carries out trend curve analysis and reservation on the hard disk.The curve that keeps utilizes function newly developed in system of window control center, can call the parametric line that random time remains, and the history curve file that calls is linked; Time to this time period limits afterwards, with look facility curve is checked, to compare or to search long parameter again.
Claims (1)
1. history parameters curve access system, comprise that Ethernet switch and programmable logic controller are PLC, it is characterized in that, parametric line harvester and man-machine picture are set, window control center is installed, establishment parametric line storing directory in man-machine picture system in harvester; Man-machine picture is connected on the parametric line harvester, and the parametric line harvester is connected with the communication board of PLC by Ethernet switch.
