Abstract
The utility model discloses a combined double-control--two-use-one-standby system controller, comprising a main loop and a control circuit, and the main loop comprises two combined controllers VF1 and VF2 wherein the output of VF1 is respectively connected with a control object M1 by the main contact point of an AC contactor KM1 and with a control object M3 by the main contact point of an AC contactor KM 13; and the output of VF2 is respectively connected with a control object M1 by the main contact point of an AC contactor KM2 and with a control object M3 by the main contact point of an AC contactor KM 23. The two combined controllers VF1 and VF2 are connected with each other by the main loop and the control loop to realize the control of two-use-one-standby state of three control objects (M1-M3). The three control objects (M1-M3) have three kinds of working-standby states: (1) M1 and M2 are working and the M3 is standby, (2)M1 and M3 are working and the M2 is standby, (3) M2 and M3 are working and the M1 is standby, thus only the control object at working state is equipped with the controller, therefore the number and capacity of the control is reduced to the hilt and the controller hardware investment cost is also reduced.
Description
Technical field
The utility model belongs to technical field of electrical automatic control, and what mainly propose is that a kind of combined two control-2 usefulness 1 are equipped with system controllers.
Background technology
In technical field of electrical automatic control, the widespread use of general industrial controller such as AC converter, soft initiator etc. has reached the critical role of not replacing now.The normal several working methods that are equipped with of several usefulness that adopt of equipment in Industry Control, it is modal mode that dual-purpose one is equipped with system.Controller also is traditional rule with Power Groud coupling (1:1 coupling) in controlling object (controlled plant).For example make a dual-purpose one of forming by 3 160KW motors and be equipped with the AC frequency conversion control system, by 2 kinds nothing more than of prior art schemes: the one controller selects for use the frequency converter of 3 same power (160KW) respectively 3 160KW pump motors to be implemented control, and the control system as 1/3 is in idle stand-by state; It two is respectively 2 160KW motors to be implemented one drag twos control with 12 times power (320KW) frequency converter, uses 1 same power (160KW) frequency converter respectively 1 160KW pump motor to be implemented control again.The thinking core of above scheme is that the power of controller and controlling object is the 1:1 coupling, in last routine system no matter whether controlling object is in the investment of stand-by state at hardware and all will disposes frequency-variable controller (capacity) for it, be that frequency-variable controller (capacity) is not according to the operate as normal equipment disposition but according to work and the configuration of standby equipment total amount, thereby cause certain idle waste the in the controller hardware investment.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of combined pair of control---2 usefulness 1 are equipped with system controller.Make it in running order controlling object Configuration Control Unit, be used for the equipment of work, realize work-stand-by state control of combination in any with minimum controller.Thereby reduce the quantity and the capacity of controller to greatest extent, reduce the controller hardware cost of investment.
The utility model is finished the technical scheme that its goal of the invention takes: it is made up of major loop and control circuit, major loop is provided with 2 controller VF1 and VF2, and the output of VF1 connects the main contacts connection controlling object M3 of controlling object M1, process A.C. contactor KM13 respectively through the main contacts of A.C. contactor KM1; The output of VF2 connects the main contacts connection controlling object M3 of controlling object M2, process A.C. contactor KM23 respectively through the main contacts of A.C. contactor KM2.
The utility model is intended to only give in running order controlling object Configuration Control Unit, is used for the controlling object of work at present state with minimum controller.In mainly being applicable to, miniwatt 2 usefulness 1 are equipped with the control occasion of system, by major loop and control loop 2 controller VF1 and VF2 are combined, realize 3 controlling object (M1-M3) are arbitrarily made with the control that dual-purpose one is equipped with state.Its middle controller VF1 and VF2 are general industrial controller (as AC converter, soft initiator etc.); Controlling object is equipment such as motor.2 controller VF1 and VF2 are combined, realize 3 controlling object (M1-M3) are arbitrarily made with the control that dual-purpose one is equipped with state.Its middle controller VF1 and VF2 are general industrial controller (as AC converter, soft initiator etc.); Controlling object is equipment such as motor.VF1, VF2 combine with 2 controllers (for example 2 AC converter), realize the dual-purpose one of 3 controlling object (for example 3 motors) M1-M3 is equipped with the control of state.VF1 and VF2 own same controlling object M3 together, under the logic control of control circuit, realize the chain interlocking of steering logic between two VF1 and the VF2.Make it have three kinds of work assembled state switching controls: (1) 1-2 combination: M1 (VF1 control) and M2 (VF2 control) duty, M3 standby (breaking away from VF1 and VF2); (2) 1-3 combinations: M1 (VF1 control) and M3 (VF2 control) duty, M2 standby (breaking away from VF2); (3) 2-3 combinations: M2 (VF2 control) and M3 (VF1 control) duty, M1 standby (breaking away from VF1).Realized the work-stand-by state control of combination in any.Each equipment all might become work and standby two states, and any 2 equipment only just can be enjoyed controller when work, break away from controller when being in stand-by state.Native system also possesses the function that the using and the reserved, dual-purpose two are equipped with; Achieve with of the various work-stand-by state control of N controller by the configuration combination N+1 above controlling object.Thereby reduce the quantity and the capacity of controller to greatest extent, stop the idle and waste of controller.The utlity model has the outstanding feature that reduces the controller hardware cost of investment to greatest extent.
