Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Example 1
The method for acquiring the efficiency of the lifter of the logistics warehouse is used for executing the delivery operation of conveying the bins for storing the articles to the conveying line from the article buffer position, and is characterized in that the lifter successively extracts at least two bins to be conveyed to the conveying line in the delivery operation, and the method for acquiring the efficiency comprises the efficiency of the delivery operation and specifically comprises the following steps:
Step 101, acquiring at least two groups of first operation time recorded by the warehouse-out operation of the elevator; each set of first operating times includes a first time at which the elevator extracts each bin from the item cache location and a second time at which the bin is placed into the conveyor line;
102, obtaining first storage time of each bin on a lifting machine according to first time and second time of each bin;
Step 103, sorting at least two groups of first operation time in ascending order according to the sequence of the first time;
104, acquiring any two adjacent first times, and acquiring two adjacent second times corresponding to the any two adjacent first times;
step 105, judging whether the first time of the next bin is earlier than the second time of the last bin, if yes, executing step 106; if not, returning to step 104 to select another group of adjacent bins;
Step 106, judging whether the second time of the next ex-warehouse bin is later than the second time of the last ex-warehouse bin, if so, executing step 107; if not, go to step 108;
step 107, calculating a first time difference between the second time of the last bin and the first time of the next bin, and then executing step 109;
Step 108, taking the first storage time of the next bin to be taken out as a first time difference value, and then executing step 109.
Step 109, obtaining the warehouse-out effective operation time of the elevator according to the first storage time of all the bins and the first time difference value of all the two adjacent bins;
and 110, obtaining the ex-warehouse working efficiency of the elevator according to the ex-warehouse effective working time.
Specifically, the efficiency obtaining method solves the work efficiency of ex-warehouse through the following formula:
wherein tst B<tetA<tetB;
when the second time of the next-out bin is not later than the second time of the last-out bin, the operation time of the next-out bin (B) is contained in the operation time of the last-out bin (A) when the elevator performs the out-of-stock operation, and the out-of-stock working efficiency is solved by the following formula:
wherein tst B<tetB≤tetA;
In the above formula, E OUT is the work efficiency of the elevator in warehouse-out, A and B are two adjacent bins extracted in warehouse-out operation, tst A is the first time of bin A, tet A is the second time of bin A, tst B is the first time of bin B, tet B is the second time of bin B, and T OUT is the total work time of the elevator in warehouse-out operation.
It should be noted that, for each piece of ex-warehouse task information of the elevator, we record the task start time, i.e. the time when the elevator starts to go to the buffer position of the material box floor where the first ex-warehouse material box is located to fetch the material box, when the task is finished, record the task end time, i.e. the time when the elevator conveys the ex-warehouse material box to the tunnel opening, the material box enters the tunnel opening from the elevator, and the total working time of the ex-warehouse operation of the elevator is obtained according to the difference of the two times;
In order to quickly identify which bin's single out-of-warehouse job of the elevator contains, the out-of-warehouse tasks in all target time ranges are sorted in ascending order by the task start time of each bin, then we calculate the task start time of the next one of every two adjacent out-warehouse tasks minus the task end time of the previous one, taking a and B above as examples of two adjacent bins extracted in the out-of-warehouse job, i.e., tst B-tetA. As can be obtained from the above inequality, if tst B-tetA >0, i.e., the two bin discharge tasks are not completed by the same operation of the elevator; if tst B-tetA is less than 0, namely the two bin delivery tasks are completed by the same operation of the elevator; if tst B-tetA =0, it is not possible to distinguish whether the outbound task a and the outbound task B are completed by the same operation of the outbound elevator, and time information of the adjacent task before the outbound task a and the adjacent task after the outbound task B is also required, however, when tst B-tetA =0, no overlapping time period is repeatedly calculated, so from the perspective of calculating the efficiency of the outbound elevator, we do not need to know whether the two bin outbound tasks are completed by the same operation of the elevator at this time.
In the embodiment, whether the hoister carries two or more bins at a time in the warehouse-out operation is effectively resolved, the acquisition mode of the warehouse-out efficiency of the hoister is further optimized, the more accurate warehouse-out efficiency of the hoister is obtained, and the subsequent improvement of the hoister can be effectively guided.

Step 201, obtaining at least two groups of second operation time recorded by each warehouse-in operation of the hoister; each set of second operating times includes a third time for the elevator to extract each bin from the conveyor line and a fourth time for the bins to be placed in an item buffer location;
step 202, obtaining second storage time of each bin on the elevator according to the third time and the fourth time of each bin;
Step 203, sorting at least two groups of second operation time in ascending order according to the sequence of the third time;
step 204, acquiring any two adjacent third times, and acquiring two adjacent fourth times corresponding to the any two adjacent third times;
Step 205, judging whether the third time of the next warehouse-in bin is earlier than the fourth time of the last warehouse-in bin, if yes, executing step 205; if not, returning to step 203 to select another group of adjacent bins;
step 206, judging whether the fourth time of the next warehouse-in bin is later than the fourth time of the last warehouse-in bin, if so, executing step 207, and if not, executing step 208;
step 207, calculating a second time difference between the fourth time of the last warehouse-in bin and the third time of the next warehouse-in bin, and then executing step 209;
step 209, obtaining the warehouse-in effective operation time of the elevator according to the second storage time of all the bins and the second time difference value of all the two adjacent bins;
and 210, obtaining the warehousing working efficiency of the elevator according to the warehousing effective operation time.
Specifically, the efficiency obtaining method solves the warehouse-in working efficiency through the following formula:
wherein tst D<tetC<tetD;
when the second time of the next warehouse-in bin is not later than the second time of the last warehouse-in bin, the operation time of the next warehouse-in bin (D) is included in the operation time of the last warehouse-in bin (C) when the elevator performs warehouse-in operation, and the warehouse-in working efficiency at the moment is solved by the following formula:
wherein tst D<tetD≤tetC;
In the above formula, E IN is the work efficiency of the elevator in warehouse out, C and D are two adjacent bins put in the warehouse in operation, tst c is the first time of bin C, tet C is the second time of bin C, tst D is the first time of bin D, tet D is the second time of bin D, and T IN is the total work time of the elevator warehouse in operation.
It should be noted that, for each piece of warehouse-in task information of the elevator, we record the task start time, i.e. the time when the elevator starts to go to the tunnel opening to get the material box, when the task ends, record the task end time, i.e. the time when the elevator conveys the warehouse-in material box to the destination floor, the material box enters the buffer position from the elevator, and obtain the total work time of the warehouse-in operation of the elevator according to the two time differences;
In order to quickly identify which bin is the one of the plurality of bins in the single-pass job of the elevator, the bins in all the target time ranges are sorted in ascending order according to the start time of each bin, then we calculate the start time of the next one of every two adjacent bins minus the end time of the previous one, taking the above C and D as examples of the two adjacent bins extracted from the bin, i.e., tst D-tetC. As can be obtained from the above inequality, if tst D-tetc >0, i.e., the two bin-entering tasks are not completed by the same operation of the elevator; if tst D-tetC is less than 0, namely the two bin warehousing tasks are completed by the same operation of the elevator; if tst D-tetC =0, it is not possible to distinguish whether the warehousing tasks C and D are completed by the same operation of the warehousing elevator according to the time information of the adjacent task before the warehousing task C and the adjacent task after the warehousing task D, however, when tst D-tetC =0, no overlapping time period is repeatedly calculated, so from the perspective of calculating the efficiency of the warehousing elevator, we do not need to know whether the two bin warehousing tasks are completed by the same operation of the elevator at this time.
In the embodiment, whether the hoister carries two or more bins at a time in the warehouse-in operation is effectively resolved, the acquisition mode of the warehouse-in efficiency of the hoister is further optimized, the more accurate warehouse-in efficiency of the hoister is obtained, and the subsequent improvement of the hoister can be effectively guided.
