Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the framed structure synoptic diagram of the preferred embodiments of the present invention;
Fig. 2 is the theory structure synoptic diagram of the preferred embodiments of the present invention;
Embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As depicted in figs. 1 and 2; A kind of embodiment of the automaton that a kind of dry-mixed mortar of the present invention is produced; The automaton that a kind of dry-mixed mortar is produced; Comprise industrial computer, the display with Ethernet interface and DCS system interface, Weighing module group, PLC unit and the printer with processing raw data function, described industrial computer is controlled the sequence of movement of whole process flow as total control with the PLC unit; All technological process configurations all are stored in the PLC unit in the production of dry-mixed mortar; The data that produced in the production run all are stored in the industrial computer, can set and revise the parameter of PLC inside through industrial computer, and can keep watch on the situation of carrying out of PLC internal processes.
The PLC unit is through exporting the relaying isolator to having the topworks of batching effect: electric motor starting valve, solenoid valve, signal lamp, electric machine controller and flow-aid device carry out start and stop.
Simultaneously the PLC unit is through importing the relaying isolator to respective switch amount signal: travel switch, stuff level switch, valve position switch, motor protecter and action generator are gathered; (1) travel switch wherein: be a limit switch of displacement-type equipment, the equipment that prevents moves outside ultra safety zone, (2) stuff level switch: the indication that is a material position of the material in the storage tank; In the time of can preventing to feed in raw material batch can is added excessive; Remind the user in time reinforced when material is used up nearly, (3) valve position switch: when valve opening is given or during the signal of closing in the PLC unit, in time to the position of PLC unit feedback valve; Prevent the card valve; (4) motor protecter: when causing motor not run well owing to faults such as overload, overcurrent, phase shortages, motor protecter is understood the power supply of automatic cut-off motor, and imports fault-signal into the PLC unit.
The signal that industrial computer received aborning feeds back on the display with the equal dynamic real-time of signal that sends; While can not make control method become lengthy and tedious again simultaneously for effective assurance equipment moves under safe condition, and above-mentioned PLC unit also has additional the analog quantity expansion module that can accept temperature signal, continuous material level signal and three kinds of analog signalses of air pressure signal and with realization entire equipment security of operation situation carried out directly effective, quick accurate real-time monitoring.
Principle of work of the present invention: the control module of weighing group is to the direct data acquisition and calculation of load cell signal; Convert the data of weighing into and be uploaded to industrial computer by the Data Control bus; Slewing rate is 200 times/second; Industrial computer cooperates the start and stop of frequency converter with the transport of controlling various aggregates simultaneously according to predefined mixing formula control PLC unit then, to reach the purpose of batching, controls a series of valves again; According to preestablishing required incorporation time various aggregates are evenly mixed, reach the purpose of mixing.
In the process of whole production, at first need check air pressure signal before the start, because valve, flow-aid device in the middle of the equipment etc. all are pneumatically work, when insufficient pressure, equipment gets into holding state; In case corresponding valve switch signal is exported, system can detect corresponding valve position switch automatically, can judge failsafe valve if signal is inconsistent, reports to the police immediately, and passes through display notifying operation personnel to failure message with the picture and text form; All motors all have motor protecter in addition; When motor causes motor not run well owing to faults such as overload, overcurrent, phase shortages; The power supply of motor protecter meeting automatic cut-off motor; Import failure message into the PLC unit simultaneously, in time take appropriate measures through display notifying operation personnel with the picture and text form again.
What describe in the above instructions is embodiment of the present invention; Various not illustrating constitutes restriction to flesh and blood of the present invention; Under the those of ordinary skill of technical field after having read instructions can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
