Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
Referring to Fig. 1, oil transfer arm working state monitoring system of the present utility model, including
Switch board, in switch board, PLC receives action command signal and is identified then sending a signal to the electromagnetic valve of difference in functionality in hydraulic pressure master station and hydraulic pressure substation again, electromagnetic valve opening and closing, and hydraulic cylinder controls oil transfer arm action;
Pressure transducer, it is arranged in fluid pressure line, and pressure transducer will detect on-the-spot fuel injection pressure signal and feed back to switch board, and switch board utilizes PLC read signal and judge oil transfer arm duty;
Touch screen, it is for the critical data of display oil transfer arm duty and each device parameter of oil transfer arm system and security situation in real time, to instruct oil transfer arm system normal operation;
Host computer, it is for receiving the oil transfer arm operating state data sent from switch board, and this host computer is also interactive with data base, to realize display in real time and the storage of data; And
Audible-visual annunciator, it is for receiving the alarm command sent of PLC in switch board and sending sound and light alarm to remind staff, and the relative recording wherein reported to the police also can be stored in data base to facilitate data query in the future.
The control principle of this utility model oil transfer arm working state monitoring system:
System adopts collection and the control mode at PLC station, by pressure transducer etc., to pressure signal and other related keyword data are acquired, record, and it is a set of to arrange color touch screen at the scene, for showing the critical datas such as each device parameter of oil transfer arm system, security situation, to instruct system normal operation.
First, after opening pump, operator are by the floating on control panel, drive knob sends action command signal to PLC in switch board, PLC receives signal and is identified the solenoid directional control valve then sending a signal in hydraulic pressure substation again, electromagnetic valve opening and closing, the oil pressure in oil circuit is driven to change, pressure transducer in Hydraulic Station by detecting on-the-spot fuel injection pressure signal and can feed back to switch board in operation room, switch board utilizes PLC read signal and judge oil transfer arm duty, finally carry out display in real time at touch screen and reach Dispatch and Command Center by Ethernet, Dispatch and Command Center is the intracardiac host computer set and data base's interaction in passing through, realize display in real time and the storage of data, if oil transfer arm departs from corresponding duty, audible-visual annunciator can be sent alarm command to remind staff by PLC, the relative recording reported to the police also can by convenient storage data query in the future.
About PLC control system:
Former control system is traditional relay formula control mode, the control of relay control system is to adopt hardware connection to realize, it is utilize the serial or parallel connection of relay mechanical contact and the hysteresis motion etc. of time-delay relay to combine and form control logic, and can be only done set logic control. And PLC control system adopts storage logic, it controls logic is be stored in internal memory with program mode (PM), will change control logic, only need reprogramming, and its good and bad contrast refers to table 1.
