Novel filter is the equipment that is used for filtering fast viscose glue impurity; Layout is disperseed; Automatic control system of the prior art can not be monitored the technology and the status of equipment of whole filtration group of planes operation in real time, and control system is loaded down with trivial details, the operation that needs the multiple parameter of monitoring to guarantee to filter a group of planes.
Summary of the invention
It is loaded down with trivial details that the present invention is intended to solve in the prior art control; Need the multiple parameter of monitoring to guarantee to filter the problem of the operation of a group of planes; Provide a kind of real-time monitoring many automatic control systems of filtering group of planes technology and equipment running status, simplified control system, guarantee viscose glue filter quality therein.
Another object of the present invention is that the history run that filters a group of planes is carried out record, makes the staff make analysis to the working condition of every filter.
In order to reach the foregoing invention purpose, concrete technical scheme of the present invention is:
A kind of automatic control system of a viscose glue contaminant filter group of planes comprises and filters group of planes automatic monitoring device and filter a group of planes, it is characterized in that: also comprise the host computer active station; Described filtration group of planes parallel connection distributes; Wherein the outlet of the viscose glue import of all filters and viscose glue all is respectively arranged with pressure transducer and pressure valve; Pressure transducer and pressure valve interconnect; And communication is connected to filter crowd automatic monitoring device, filters group of planes automatic monitoring device and is connected with the communication of host computer active station again; Filter group of planes automatic monitoring device and gather pressure signal through pressure transducer, again the pressure signal that collects is sent to the host computer active station, upper active station is through the analysis to signal, controlled pressure valve.
Filtration group of planes automatic monitoring device of the present invention comprises PLC control module, process data interface unit and filters the on-the-spot automatic control equipment of a group of planes.
The automatic control system of a viscose glue contaminant filter group of planes of the present invention is to be set up by the control module that three filters of a cover control system control are controlling models.
Filter crowd automatic monitoring device of the present invention is one 250 ohm a resistance of series connection in the input loop of filter crowd automatic monitoring device through the pressure transducer acquired signal, the current signal of 4-20mA is converted to the voltage signal of 1-5V.
Host computer active station of the present invention is the WinAC control station that a PC is set up.
WINCC and STEP7 configuration program are installed on the above-mentioned PC.
The useful technique effect that the present invention brings:
1, the present invention has adopted automatic control system that filtering technique in the viscose glue production technology is monitored, and has realized standardization, automation mechanized operation, has stablized production technology, makes technological parameter more accurate; And alleviated labour intensity; Reduced the generation of technology accident; And be different from prior art and must control multiple parameter and guarantee equipment operation, only need monitoring viscose glue inlet and outlet pressure just can realize that a group of planes filters and the control of cleaning to filtering, effectively controlled cost;
2, automatic monitoring device of the present invention comprises the system of step control; Form by PLC control module, process data interface unit and the on-the-spot automatic control equipment of a filtration group of planes; Sharing and disperse through control task; Improve the ability to ward off risks of control system, the load of Adjustment System control has rationally been realized the efficient operation of system;
3, the automatic control system of a viscose glue contaminant filter group of planes of the present invention is to be set up by the control module that three filters of a cover control system control are controlling models; Realized modularization programming like this; Increase substantially the scalability of system; When controlling configuration afterwards and expanding, only this standard control module need be simply called, just expanded function can be conveniently realized;
4, filter crowd automatic monitoring device of the present invention is one 250 ohm a resistance of series connection in the input loop of filter crowd automatic monitoring device through the pressure transducer acquired signal; The current signal of 4-20mA is converted to the voltage signal of 1-5V; So just pressure boost measuring-signal point has separately been practiced thrift system resource;
5, host computer active station of the present invention is the WinAC control station that a PC is set up, and WINCC and STEP7 configuration program are installed on the PC.On this PC, promptly realize system control function, control configuration function, realized the control operation function again, significantly practiced thrift the investment of system's construction.
