The model utility content
The utility model technical problem to be solved 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 utility model 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, the beneficial effect of the utility model is:
Because the control system of a kind of intelligent electric final controlling element of the utility model 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 the utility model antijamming capability is strong, wiring simple, debugging is easier to.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: main control unit 10, motor drive unit 12, display screen 14, knob plate 16, power supply 18; Motor 20, operation knob 22, mode knob 23, torque sensor 24, bus card 26; FCS control system 28, data processing unit 30, communication interface 32 drives isolator 34; First signal isolator 40, secondary signal isolator 36, valve position absolute encoder 38, temperature transducer 25.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details
Control system referring to a kind of intelligent electric final controlling element shown in Figure 1; Comprise main control unit 10, motor drive unit 12, torque sensor 24, valve position absolute encoder 38, display screen 14 and knob plate 16; The motor drive unit 12 that wherein is used for drive motor 20 work is connected with power supply 18, motor 20; Knob plate 16 is provided with operation knob 22 and mode knob 23; The specialization of the utility model is: in control system, also be provided with bus card 26 and FCS control system 28; FCS control system 28 is connected with main control unit 10 through bus card 26, and bus card 26 is provided with data processing unit 30, first signal isolator 40 and the communication interface 32 of the input data being carried out analysing and processing, and data processing unit 30 is connected with communication interface 32 through first signal isolator 40; Being provided with of bus card 26 reduced system's external cabling, also makes debugging, maintenance simpler simultaneously.
Motor drive unit 12 is connected with main control unit 10 through driving isolator 34; The setting of this driving clutch 34 can effectively make motor drive unit 12 work stably; Simultaneously can also effectively prevent motor drive unit 12 overload runnings; Between motor 20 and main control unit 10, be provided with temperature transducer 25; The effect of this temperature transducer 25 be with the temperature on the motor 20 promptly and accurately feed back to main control unit 10, thereby main control unit 10 judges according to the temperature of temperature transducer 25 feedbacks whether motor transships motor is controlled timely and effectively that so motor 20 normal operations can be effectively protected in the setting of temperature transducer 25.
Being provided with of first signal isolator 36, secondary signal isolator 40 can the effective isolation undesired signal, makes control system more stable.Digital signal has the characteristics of free-error transmission, thereby makes the more accurate of system's control.
