Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with accompanying drawing
Step ground is described in detail.
As shown in figure 1, a kind of method of operating for ammeter electric detection means provided for the embodiment of the present invention one, institute
The method of stating includes：
Step S101, one or more automatic list item computation schemas and its corresponding trigger region are shown, the automatic list item
Computation schema includes single-phase meter computation schema and three-phase meter computation schema；
Step S102, when getting the selection instruction that user sends to the trigger region of a certain automatic list item computation schema
When, then selected list item computation schema automatically is performed, and after selected list item computation schema automatically is entered, obtain user's typing
Corresponding data, actual value and compares when obtaining that theoretical value and ammeter are often converted when ammeter is often converted, and is judged according to comparative result
Go out the current health state of the ammeter revolution；Wherein, the health status includes fast, normal and partially slow.
Detailed process is can to respectively enter two kinds of automatic computation schemas according to the selection of response user, judges that ammeter turns
Several current health states.
The first automatic computation schema is single-phase meter computation schema, when getting triggering of the user to single-phase meter computation schema
During the selection instruction that area sends, then single-phase meter computation schema is performed, and after into single-phase meter computation schema, obtain user's record
Current value, magnitude of voltage and the electric meter constant for entering, obtains theoretical value T when ammeter is often converted, and obtains the revolution of user's typing, according to

Value pattern, and after into input current value pattern, the corresponding data of user's typing is obtained, obtain theoretical when ammeter is often converted
Value T, and the revolution of user's typing is obtained, the initial time and end time according to record obtains actual value when ammeter is often converted
K；And
Actual value K is compared when theoretical value T and ammeter are often converted when the ammeter for obtaining often is converted, and according to comparing knot
Fruit judges the current health state of ammeter revolution.
According to site environment, actually measure for primary current value, therefore primary current value is touched when get user
When sending out the selection instruction that area sends, perform primary current value, after into after primary current value, obtain user's typing multiplying power, three
Phase current values, magnitude of voltage, electric meter constant and power factor, obtain theoretical value T when ammeter is often converted, and obtain turning for user's typing
Number, the initial time and end time according to record, obtains actual value K when ammeter is often converted；And by the ammeter for obtaining per turn
Actual value K is compared when used time theoretical value T and ammeter are often converted, and judges the current strong of ammeter revolution according to comparative result
Health state.Wherein, theoretical value T=3600*3* multiplying power/three-phase electricity flow valuve summation/magnitude of voltage/electric meter constant when ammeter is often converted/
1.732/ power factor.As an example, select curent change smaller according to input, the three-phase meter of measure field actual measurement
Current value, magnitude of voltage, multiplying power, electric meter constant value, the primary current value being entered manually under three-phase meter computation schema, click calculating
Button, three-phase meter information is calculated and exports single three-phase meter per turn (pulse) used time theoretical value.Can |input paramete include：Multiplying power is (silent
Recognize 5), three-phase current (A, give tacit consent to 5A), voltage (V gives tacit consent to 0.4kV), electric meter constant (C, acquiescence 800), power factor (acquiescence
0.9).Output item includes：Ammeter is per turn (pulse) used time theoretical value (T), a circular speed judged result (fast, normal, partially slow).
According to site environment, it is impossible to measure primary current value, actually can only measure for secondary current value, therefore when obtaining
During the selection instruction sent to the trigger region of secondary current value to user, secondary current value is performed, after into secondary current value,
Three-phase electricity flow valuve, magnitude of voltage, electric meter constant and the power factor of user's typing are obtained, theoretical value T when ammeter is often converted is obtained, and
The revolution of user's typing is obtained, the initial time and end time according to record obtains actual value K when ammeter is often converted；And
Actual value K is compared when theoretical value T and ammeter are often converted when the ammeter for obtaining often is converted, and is judged according to comparative result
The current health state of ammeter revolution.Wherein, theoretical value T=3600*3/ three-phase electricity flow valuve summation/voltage when ammeter is often converted
Value/electric meter constant/1.732/ power factor.It should be noted that the information difference of secondary current value and the input of primary current value
It is that primary current value has multiplying power, and secondary current value does not have.
It is theoretical when when ammeter is often converted, actual value K≤0.9* ammeters are often converted in the automatic computation schema of above two
During value T, judge that ammeter revolution is fast；Theoretical value T when 0.9* ammeters are often converted<Actual value K when ammeter is often converted<1.1* ammeter
When often converting during theoretical value T, judge that ammeter revolution is normal；Manage when when ammeter is often converted, actual value K >=1.1* ammeters are often converted
During by value T, judge that ammeter revolution is partially slow.
Step S103, meter type of alarm judgment model and its corresponding trigger region are shown, when getting user to meter
During the selection instruction that the trigger region of type of alarm judgment model sends, then selected meter type of alarm judgment model is performed, and
After into after meter type of alarm judgment model, one or more warning messages and its corresponding trigger region are shown, when obtaining again
When getting the selection instruction that user sends to the trigger region of the warning message, then corresponding warning message is shown.
Specifically, the different information according to ammeter dial plate, user can select identical information to show on device
Corresponding trigger region, the selected trigger region of triggering, so as to get the picture and text explanation of ammeter status or fault type.Can be with
It is understood by, the meter type of alarm judgment model is used for when the information suggested by user cannot determine current ammeter dial plate,
The current suggested information of ammeter is instructed and known by picture and text explanation.
It should be noted that trigger region includes but is not limited to the modes such as executable button, link, when trigger region is button
