Abstract
The present invention relates to a kind of method applying two-wire system motor control electrical ball valve on intelligence instrument, its feature is, the size of current that can be rotated according to direct current generator and rotation time, to judge whether electrical ball valve puts in place the stall with whether, that is,:After performer motor starts to rotate forward or invert, start to detect driving current, if driving current is more than current threshold, then judge whether driving time is more than time threshold.This control method passes through the two lines of intelligence instrument performer motor it is not necessary to increase location switch it is possible to realize the unlatching/detection of closing and put in place of electrical ball valve.The present invention is applied to the control of intelligence instrument two-wire system motor, has the advantages that strong antijamming capability, working stability, low cost, life-span length, simple and convenient assembly.
Description
Technical field
The present invention relates to intelligence instrument executor's control technology, specifically on intelligence instrument, application two-wire system is straight
The technology of stream motor control electrical ball valve.
Background technology
In intelligence instrument executor (direct current generator) control technology, in order to detect actuator turns electrical ball valve
Whether put in place, most designs all adopt the five-wire system executor with location switch, two electricity at present
Three electrical ball valves of machine control line put in place detection line (reaching position and pass to put in place).
Because location switch is mechanical contact, situations such as there is senile abrasion, and short life, volume are big, high cost,
Processing technique is complicated, and each executor producer does not seek unity of standard at present.Need to judge that executor turns during detection stall
Dynamic arrival time, now power consumption is big, have impact on the control effect to executor for the intelligence instrument；In addition, executor
After water inlet, five-wire system motor location switch is inoperative, leads to intellectual water meter control section to be damaged, motor cannot drive
Dynamic.
Content of the invention
In view of there is many unreliable factors in traditional five-wire system motor control method, the purpose of the present invention is:Carry
For a kind of can according to direct current generator rotate size of current and rotation time judge electrical ball valve whether put in place with
The method whether blocking, that is, provide a kind of reliable control technology of intelligence instrument executor (direct current generator).
Method of the present invention flow process：
When performer motor drives (rotating and reverse), real-time detection DC motor Driver size of current, root
Go out putting in place and stall of electrical ball valve according to driving current size and arrival time in time detection.
Performer motor will execute closing and opening action>Testing circuit current threshold
—>In time threshold, if circuital current is more than threshold value, then electrical ball valve occurs stall phenomenon；
—>During to time threshold, circuital current be more than current threshold after it was demonstrated that performer motor is electrical ball valve
Close and open and put in place.
It is an advantage of the invention that：This control method passes through the two lines of intelligence instrument performer motor it is not necessary to increase
It is added to bit switch it is possible to realize the unlatching/detection of closing and put in place of electrical ball valve.Performer motor band galvanic electricity
Dynamic ball valve to control the opening and closing of ball valve in the way of forward or reverse, by the drive of real-time detection to valve
Streaming current size, judges putting in place and stall of electrical ball valve in time.The present invention has real-time, reliability
Height, strong antijamming capability, low cost, reduce power supply power consumption, and assembling product process is simple.
With reference to the accompanying drawings and examples, the present invention will be further described.
Brief description
Fig. 1. the two-wire system performer motor of intelligence instrument controls the schematic flow sheet of electrical ball valve
In figure, IDIt is driving current；IMIt is current threshold；TDIt is driving time；TMIt is time threshold.
Specific embodiment
The method that a kind of embodiment intelligence instrument two-wire system performer motor controls electrical ball valve
The intelligence instrument of the present embodiment is intellectual water meter, and performer motor is DC micro-motor.
Fig. 1 shows the detailed control flow of the present embodiment, in figure:IDIt is driving current；IMIt is current threshold；
TDIt is driving time；TMIt is time threshold.
1) after performer motor starts to rotate forward or invert, start to detect driving current ID, i.e. sample motor electricity
Pivot electric current；
2) if driving current IDMore than current threshold IM, then judge driving time TDWhether it is more than time threshold
TM:
A) if greater than time threshold TM, then performer motor rotate in place, otherwise performer motor stall；
B) if driving current IDIt is not more than current threshold IM, then judge driving time TDWhether it is more than time threshold
Value TM:
B1) if greater than time threshold TM, then it is judged as that performer motor line does not connect；
B2) if no more than time threshold TM, then continue to judge driving current IDWhether it is more than current threshold IM.
