Description
Technical field
The utility model relates to a kind of YE, relates in particular to a kind of Modbus bus control system of YE.
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
The utility model technical problem to be solved provides that a kind of antijamming capability is strong, wiring is simple, the Modbus bus control system of the easier YE of debugging.
For solving the problems of the technologies described above; The utility model provides a kind of Modbus bus control system of YE; 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 motor with power supply, and said knob plate is provided with operation knob and mode knob, and said control system also comprises Modbus bus card and FCS control system; Said FCS control system is connected with said main control unit through the Modbus bus card, and said Modbus 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 this 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.
Compared with prior art, the beneficial effect of the utility model is:
Because the Modbus bus control system of a kind of YE of the utility model is provided with Modbus 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; The Modbus 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.

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, Modbus 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
Modbus bus control system referring to a kind of YE 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 Modbus bus card 26 and PCS control system 28; PCS control system 28 is connected with main control unit 10 through Modbus bus card 26, and Modbus 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 Modbus bus card 26 reduced system's external cabling, also makes debugging, maintenance simpler simultaneously.
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.
Main control unit 10 in the utility model adopts digital serial communication with Modbus bus card 26, and Modbus bus card 26 adopts bus communication with FCS control system 28, has realized the intelligent digital control of YE; The transmission of control signal adopts digital signal to transmit; Utilize digital signal to have stronger antijamming capability, the characteristics of free-error transmission make the transmission more stable of The whole control system signal; Control more accurate; Reduced the wiring number of control system in addition, made system wiring oversimplify, thereby make system debug also be easier to.
In sum, thus the utility model not only antijamming capability is strong, wiring is simple, and the debugging be easier to.
The above is merely the preferred embodiments of the utility model; The protection domain of the utility model does not exceed with above-mentioned mode of execution; As long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
