Description
Technical field
The present invention relates to a kind of YE, relate in particular to a kind of control system of intelligent electric final controlling element.
Background technique
YE is called electric actuator again.It is a kind of drive unit that utilizes certain driving source and straight line is provided under certain control signal effect or rotatablely moves; The energy is taken conveniently because it has, signaling rate is fast, long transmission distance, be convenient to central controlled advantage, is usually used in supporting various valve and constitutes electric valve or electric control valve, at present the existing YE that is used for supporting valve; Normally adopt analogue signal to control; Since the antijamming capability of analogue signal a little less than, transmission error is big, thereby causes the control accuracy of YE lower; In addition, adopt analogue signal control also to have wiring is complicated, system debug is relatively more difficult defective and problem.
Summary of the invention
Technical problem to be solved by this invention provides the control system that a kind of antijamming capability is strong, wiring simple, debug easier intelligent electric final controlling element.
For solving the problems of the technologies described above; The present invention provides a kind of control system of intelligent electric final controlling element; Comprise main control unit and the motor drive unit that is connected with said main control unit, knob plate, torque sensor, valve position absolute encoder and display screen; Said motor drive unit is connected with power supply, motor, and said knob plate is provided with operation knob and mode knob, and said control system also comprises bus card and FCS control system; Said FCS control system is connected with said main control unit through bus card, and said bus card is provided with interconnective data processing unit and communication interface.
Said motor drive unit is connected with said main control unit through driving isolator.
Said motor is provided with temperature transducer, and said temperature transducer is connected with said main control unit.
Said operation knob is connected with said knob plate through the secondary signal isolator with said mode knob.
Said data processing unit is connected with said communication interface through first signal isolator.
Said bus card is the profibus bus card.
Said bus card is the Modbus bus card.
Said bus card is the Devicenet bus card.
Compared with prior art, beneficial effect of the present invention is:
Because the control system of a kind of intelligent electric final controlling element of the present invention is provided with bus card and FCS control system, thereby realized the intelligent digital control of YE, the transmission employing digital signal of control signal is transmitted; Because digital signal has stronger antijamming capability; The characteristics of free-error transmission, thus make that the transmission of The whole control system signal is more stable, control more accurate; Bus card is provided with the wiring number that control system has been lacked in letter in addition; Make system wiring oversimplify, thereby make system debug also be easier to, so antijamming capability of the present invention is strong, wiring simple, debugging is easier to.
