Traversing the axle counting section state data set, and under the condition that the state data of the two adjacent axle counting sections meet the counting starting condition, starting to count the axle count maximum value of the axle counts of the two adjacent axle counting sections, and taking the axle count maximum value as an axle count statistic value;
Based on a plurality of axle count statistics corresponding to the axle count section axle array, obtaining a total axle count corresponding to the axle count comprises the following steps:
And accumulating the shaft number statistical values obtained in the process of traversing the shaft counting section state data set, wherein in the adjacent two shaft counting section state data, the former shaft counting section state data is a section occupied state, and the latter shaft counting section state data is a section idle state, and taking the accumulated result of the shaft number statistical values as the total shaft number of the corresponding shaft counting.
It will be appreciated that the specific steps for calculating the total number of occupied axes and the total number of axes using the modes 1 and 2 are as follows:
Mode 1:
(1) Total occupied times:
Traversing array D A, sum_ occupyA is incremented by 1 when O Ai-1 =0x55 and O Ai =0xaa.
(2) Total number of axes:
1) Traversing array D A, starting statistics when O Ai-1 =0x55 and O Ai =0xaa;
2) After the statistics starts, comparing C Ai with C Ai-1, and taking the maximum value as the maximum value axleMaxA of the axis number of the statistics;
3) The statistics are ended when O Ai-1 =0xaa and O Ai =0x55, and axleMaxA is accumulated to obtain the total axis number sum_ axleA =sum_ axleA + axleMaxA in the time period T A1 to T An.
Mode 2:
(1) Total occupied times:
Traversing array D A, sum_ occupyA plus 1 when O Ai-1 =0x55 and O Ai =0xaa, or when O A1 =0xaa and C A1 =1;
(2) Total number of axes:
1) Traversing array D A, starting statistics when O Ai-1 =0x55 and O Ai =0xaa, or when O A1 =0xaa and CA 1 =1;
2) After the statistics starts, comparing C Ai with C Ai-1, and taking the maximum value as the maximum value axleMaxA of the axis number of the statistics;
3) The statistics are ended when O Ai-1 =0xaa and O Ai =0x55, and axleMaxA is accumulated to obtain the total axis number sum_ axleA =sum_ axleA + axleMaxA in the time period T A1 to T An.
The difference between the two calculation methods is that the first piece of data is judged, if the first piece of data is in the mode 1, normal calculation is performed, if the first piece of data is in the mode 2, whether the first piece of data can be used as a calculation trigger condition is judged, wherein the judgment condition is that O A1 =0 xAA and C A1 =1.
Taking the earlier time (here assumed to be T A1) in T A1 and T B1 as the start time, the later time (here assumed to be T Bn) in T An and T Bn as the end time, and according to the total occupancy times and the total axis number output by the axis counting data analysis module, the final evaluation conclusion can be obtained:
In the time period from T A1 to T Bn, the total station use times of the first counting shaft which is already applied in engineering is sum occupyA, the total shaft number is sum axleA, the total occupied times of the second counting shaft to be verified is sum occupyB, the total shaft number is sum axleB, if sum occupyA is equal to sum occupyB, sum axleA is equal to sum axleB, and the engineering application parameters of the second counting shaft and the first counting shaft are consistent in the time period, so that the second counting shaft to be verified preliminarily has engineering application conditions.
