Detailed Description
The following further describes embodiments of the present invention:
example 1
As shown in fig. 1, the method for determining the operation state of a power transmission line channel visualization image device according to the present invention includes the following steps:
1. obtaining the self-defined offline duration t in the current time now of the system, a3, and changing DWBT and DWET to 00 in a 2: time 00:00 is converted into positive integers btm and etm in minutes, and the four values are passed as parameters to b3 as a callatestarttime ()
2. The main logic of the callatestarttime method comprises the following steps:
the current time now is converted into the number of minutes to the morning now _ Min, the required working time (unit: minute) work _ time in one day is calculated according to the difference between btm and etm, the total number of minutes day _ Min is 24 x 60 minutes, and the number of days of increase is required to be calculated, i.e. t/work _ time. The morning minutes time is defined as 0 x 60 minutes.
3. A temporary variable Temp is defined for storing the time value (the difference between the current time minus the working time and the starting working time) to be calculated, i.e., Temp — now _ Min- (t% work _ time) -btm.
Note: % represents the remainder operation
4. Comparing which time period in the day the current time is in;
a. if after the end of the working time of the day, now Min etm, now time is the current time minus the remainder of the end working time and t and work time, now the calculated time res _ DT should be:
times＝now_Min-(etm-(t％work_time))；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
thus, when t is larger than the working time, the working time point of the previous day is located.
b. If between the beginning working time and the ending time of the working time of the day, that is btm < ═ now _ Min < ═ etm, then the time at this time needs to judge the size of temp:
b1, if temp is positive, that is, the absolute value of the difference between the starting working time and the ending working time is less than the self-defined off-line time t, then time is the remainder of t and work _ time, and the calculated time res _ DT at this time should be:
times＝t％work_time；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
b2, if temp is negative, that is, the absolute value of the difference between the starting working time and the ending working time is greater than the off-line time t set by the user, then time at this time is the difference between the current time now _ Min and the non-working time of the previous day plus the difference between the working times, and the calculated time res _ DT at this time should be:
times＝now_Min-(etm-temp)；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
c. if before the start working time of the day, i.e. now _ Min < ═ btm, then time at this time is the current time minus the difference between the working time of the previous day and the non-working time and the remainder of t and work _ time, the time res _ DT calculated at this time should be:
times＝now_Min+day_Min-etm-(t％work_time)；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
thus, when t is larger than the working time, the working time point of the previous day is located.
5. After the offline reference time OLT of the image equipment is calculated, the PCD or PSD stored in the database of the equipment is only required to be sequenced, the largest piece of data is taken out and put into a cache, namely the latest piece of data of each equipment is stored in the cache, and then the PCD or PSD is used for comparing with the OLT, if the OLT is larger, the equipment is in an offline state, otherwise, if the OLT is smaller, the equipment is in an online state.
6. According to the calculation result, the states of all the devices are distinguished and stored in a library by using a zone bit, then the difference value of btm and etm is divided by CP, the number of the pictures which should be uploaded in the working time of the day can be calculated, the number of the pictures which are actually uploaded by the devices can be calculated according to the number of records in the database, therefore, the data is summarized and analyzed, the effective access rate statistical result of the devices is obtained, and the effective access rate statistics can be used for counting how many devices belong to the devices which are well accessed according to the mode of considering the set percentage. That is, the effective access rate is set to 95%, which means that if 100 pictures are uploaded every day by each device, the actual number of uploads exceeds 95 to be determined that the device is sound.
Example 2
On the basis of example 1, the following elucidation of the process is carried out in the form of simulation data:
assuming that the current device start operation time is 08:00:00 and the end operation time is 18:00:00, then the corresponding btm is 8 × 60-480, and etm is 18 × 60-1080, the total operation duration of the whole day is 24 × 60-1440, the current date is 10.1 days, and assuming that the offline duration is determined to be 12 hours (12 × 60 minutes), i.e., t > etm-btm, the following results can be obtained by calculation:
when the present time now 0< now < btm, now suppose 05:00
According to the description of the fourth item c, there are:
times＝now_Min+day_Min-etm-(t％work_time)；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
times＝5*60+1440-1080-(720％600)＝300+1440-1080-120＝540
res_DT＝300.addSecs(-60*(540+1440*1))
i.e., 540+1440 minutes ahead of the current time 300, i.e., 16:00 of the previous day
Example 3
On the basis of example 1, the following elucidation of the process is carried out in the form of simulation data:
when the present time now is after btm and before etm, i.e. btm < now < etm, assuming now 15:00:00 as described in the fourth b2, then:
temp＝now_Min-(t％work_time)-begin_Min if(temp>＝0)
{
times＝t％work_time；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
}else{
times＝day_Min-(end_Min-temp)；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
}
temp＝15*60-(12*60％(1080-480))-480＝300
times＝900-1080+300＝120
res_DT＝900.addSecs(-60*(120+1440*1))
i.e., 120+1440 minutes ahead of the current time 900, i.e., 13:00 of the previous day
According to the description of the fourth b1, there are: the modification t is 8 hours, then:
temp＝now_Min-(t％work_time)-begin_Min if(temp>＝0)
{
times＝t％work_time；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
}else{
times＝day_Min-(end_Min-temp)；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
}
temp＝15*60-(8*60％(1080-480))-480＝-60
times＝-60
res_DT＝900.addSecs(-60*(-60+1440*1))
i.e., the current time 900 is moved forward by-60 +1440 minutes, i.e., 17:00 of the previous day
Example 4
On the basis of example 1, the following elucidation of the process is carried out in the form of simulation data:
when the present time now is after etm, before etm, i.e. etm < now <24:00:00, it is assumed to now be 20:00:00
According to the description of the fourth b2, there are:
according to the description of the fourth a, there are:
times＝now_Min-(etm-(t％work_time))；
res_DT＝res_DT.addSecs(-60*(times+day_Min*dates))；
times＝20*60-(18*60-(12*60％600))＝240
res_DT＝1200.addSecs(-60*(240+1440*1))；
i.e., 240+1440 minutes ahead of the current time 1200, i.e., 16:00:00 of the previous day.
