Call out the current soft pressing plate of protection device.
4) if Sver=0, then calling protection device current version number, (i.e. last with standard version number
The protection version number patrolled and examined) compare, if inconsistent, Sver=10.If Sver=10, do not call
The current soft pressing plate of protection device.
5) (this preset time period can be according to reality in first 1 hour to inquire about first protection event generation from history library
Border needs and arranges, and the present embodiment illustrated as a example by 1 hour) total action on the same day of this protection device time
(this preset times threshold value can be arranged number Ttoday > 2 according to actual needs, and the present embodiment enters as a example by 2 times
Row explanation), then (this first action frequency can be according to actual need to arrange protection device total action frequency Snum=10
Wanting and arrange, the present embodiment illustrates as a example by 10), and after 3 hours, automatic resetting is that 0 (this always moves
Making number of times resetting value can arrange according to actual needs, the present embodiment illustrates as a example by 0)；Snum writes from memory
Think 0；The same day, total action frequency Ttoday was defaulted as 0；
6) inquire about first protection event from history library and occur whether first 1 hour this protection device has communication
Interrupt event occurs, if having, arranging middle connection breaking number of times Sdisc=5, and after 3 hours, automatic resetting is 0；
Sdisc is defaulted as 0；
7) if first protection venue location time is in the 7 of default first time period, i.e. every day:
00 to 23 point, then arranging the activity time is the first active time value Stime=5；Otherwise Stime=0；
8) if time when receiving this protection event with protection put into operation time difference Tyear < 1 year, and
And there is not maintenance, then Srun=5 in current this protection of year；If 1 < Tyear < 10, and working as
Maintenance number of times < 3, the then Srun=5 that this protection of front year occurs；Srun=0 in the case of other；
9) according to computing formula Sscore=Sset+Slink+Svolt+Sver+Snum+Sdisc+Stime+Srun,
Calculate the value of Sscore.
Step 6: total score Score is compared with standard scores, judge protection event be overhaul data still
Regular event data.Result is charged in the maintenance labelling Tag of this device, comprise this device and overhaul each time
Time and total number.Flow process is as follows,
1) if 35≤Sscore, then judge this action event as overhaul data, juxtaposition total action on the same day time
Number Ttoday adds 1.
2) if 25 < Sscore < 35, then judge this action event as doubtful overhaul data, juxtaposition was total for the same day
Action frequency Ttoday adds 1.
3) if 10 < Sscore < 25, then judge this action event as doubtful action data, juxtaposition was total for the same day
Action frequency Ttoday adds 1.
4) if Sscore < 10, then judge that the same day, as regular event data, and is always moved by this action event
Make number of times Ttoday and add 1.
