The process flow diagram of the display packing of the current break that Fig. 2 provides for the embodiment of the present invention two.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the process flow diagram of the display packing of the current break that Fig. 1 provides for the embodiment of the present invention one, the method can comprise:
Step S11: the current value of deriving circuit in first time period is the first numerical value.
Set a specific duration, within the time period meeting this duration, the mean value of obtaining current, and the mean value obtained is derived, be recorded as the first numerical value.
Step S12: the described current value of deriving described circuit in second time period is second value.
Get the current average in the next time period adjacent with the above-mentioned time period, and this current average is derived, and be recorded as second value.
Step S13: the absolute value obtaining the difference of described second value and described first numerical value is third value.
After acquisition first numerical value and second value, two numerical value are subtracted each other, gets the absolute value of two quantity difference, be recorded as third value.
Step S14: judge whether described third value is greater than default value, if so, then performs step step S15, if not, then performs step step S11.
Made comparisons by the default value preset in the third value obtained and system, the magnitude relationship of both judgements, if third value is greater than default value, then enters step S15; If not, then enter step S11, continue to repeat the current value of deriving subsequent time period, thus continually electric current in circuit to be monitored, with Timeliness coverage fault.
Step S15: determine that described circuit is faulty circuit, show described circuit name, performs step step S11.
When third value is greater than default value, then illustrate that the sudden change of electric current in time adjacent segments has exceeded limit value, circuit is very likely had to there occurs fault, now, be faulty circuit by this Circuit display, and the title of display circuit, thus make track walker know the position of faulty circuit fast, and then circuit is overhauled.
The display packing of the current break that the embodiment of the present invention provides, continual current value can be monitored, and the current value monitored is derived, draw the difference of two groups of current values in time adjacent segments, compare the absolute value of difference and the size of default value, if be greater than default value, then illustrate that current value sudden change is larger, probably have circuit to trip, monitoring personnel can observe the circuit broken down in the very first time, thus overhaul.The method can demonstrate the sudden change value of electric current fast and accurately, thus determines faulty circuit in time.
On the basis of above-described embodiment one, the embodiment of the present invention additionally provides the second embodiment, and embodiment two carries out improving on the basis of embodiment one, and the particular flow sheet of this embodiment two as shown in Figure 2.
On the basis of embodiment one, the embodiment of the present invention two can also comprise following content:
Between step S13 and step S14, also step S16 can be comprised: arranged in order by third value.
After acquisition third value, third value can be arranged by ascending order or descending, thus can the maximal value of quick position current break.
After step s 14, also can comprise step S17: call macro program judges third value, if third value is greater than default value, then report to the police.
After macroprogram is set, judge whether third value exceedes default value by macroprogram, if exceeded, then send alarm, alarm can guarantee that monitoring personnel find current break fast further, even if monitoring personnel do not monitor temporarily, alarm also can notify that it may have line failure in time.
Before step S11, also S18 can be comprised: setting default value.
Before beginning derived current value, first setting the default value that can judge fault, after having had default value, when obtaining third value by the first numerical value and second value, can judge third value fast.
