a memory for storing a program;
and the processor is used for loading the program to execute the mobile phone inspection and attendance checking method based on the two-dimensional code and the GPS.
The invention is further described with reference to the drawings and the specific examples.
As shown in fig. 2, the mobile phone inspection and attendance checking method based on the two-dimensional code and the GPS comprises the following steps:
A. and determining the standard path length of the routing inspection route. Generally, one routing inspection route at least comprises two attendance points, and two-dimensional codes are pasted in the attendance points. In some embodiments, the standard path length of this step may be calculated by measuring GPS coordinates of each attendance point, if the GPS coordinates of attendance point a are (XA, YA) and the GPS coordinates of attendance point B are (XB, YB), the distance between attendance point a and attendance point B may be calculated by a coordinate distance formula, and the distance between AB is equal to the distance between attendance point a and attendance point B
The distance obtained is the standard path length L. In other embodiments, one inspection route includes a plurality of attendance points, for example, an attendance point a, an attendance point B, and an attendance point C in sequence, and the standard path length L may be obtained by adding the distance between the points AB and BC.
B. And recording GPS positioning data when the first inspector scans the two-dimensional code of the attendance point. When a first inspector scans the two-dimensional code of a certain attendance point, the mobile phone of the first inspector can trigger the APP to call the GPS interface to acquire the current position data, and the acquired GPS data can be stored in the local APP of the mobile phone or uploaded to the server through a mobile phone network. In some embodiments, the APP may be WeChat, Paibao, or other APP with code scanning and network communication capabilities.
C. And calculating the path length of the first inspector for the current inspection according to the GPS data of the first inspector. The APP or the server of the mobile phone can calculate the position between two points according to the GPS positioning data generated by the first inspector when the two attendance points scan the two-dimensional code. The calculation method can adopt a distance formula between two points for calculation.
D. And calculating the average difference value of the path lengths of the first patroller patrolling according to the path length of the first patroller patrolling this time, the standard path length and the historical path length (namely the path length of the first patroller patrolling each time on the patrolling route) of the first patroller patrolling on the patrolling route.
The calculation formula of the average difference value of the routing inspection path lengths is as follows:
Dmn＝((Lm1-L)+(Lm2-L)+…+(Lmn-L))/n；
Dmnaverage difference in path length for the nth inspection of the mth inspector, LmnThe path length of the nth inspection for the mth inspector is shown, and n represents the number of times of inspection. The main meaning of the formula is to calculate the difference between the path length of each inspection and the standard path length, and average the difference of multiple historical inspections, thereby reducing the system error. In some embodiments LmnAnd the path length of the nth inspection for the mth inspector refers to the distance between two attendance points calculated according to the GPS data of the mth inspector. In other embodiments, the path length refers to the sum of adjacent distances of a plurality of arranged attendance points calculated according to the GPS data of the mth inspector, for example, if an attendance route includes attendance point a, attendance point B and attendance point C, the path length refers to the distance between AB plus the distance between BC. The calculation principle of the formula is thatWhen an inspector inspects on the same inspection route, under the condition that the positions of the mobile phone and the attendance point are the same (namely under the condition that the influence factors of GPS positioning are the same), the path length of inspection measured each time is the same, so that the L is theoretically the samem1＝Lm2＝…＝LmnThus, push Dm1＝Dm2＝…＝Dmn(ii) a Therefore, once the route of the inspector for the current inspection is deviated (the checking-in position is not right), D can be enabledmnThe value is changed greatly, so that the problem can be found by comparing the average difference value of the path lengths of the current patrol and the last patrol. In addition, in some embodiments, after the attendance of the inspector is judged to be abnormal, the method further comprises the step of rejecting the current attendance data, so that the current abnormal data are prevented from influencing the next attendance calculation, and the step can be manually completed or automatically completed by a server or a mobile phone.
E. And the average difference value of the path length of the current routing inspection by the first inspector is differed from the average difference value of the path length of the last routing inspection by the first inspector to obtain a first difference value.
F. And judging whether the first difference value belongs to a first set numerical range, if so, judging that the current inspection state of the first inspector is normal, and otherwise, judging that the current inspection state of the first inspector is abnormal. The purpose of setting the first difference is to set a certain fault tolerance for the system. And if the numerical range of the first difference value is within the allowable range, judging that the current inspection state of the first inspector is normal. In some embodiments, the first set range of values is: [ -0.1Dm(n-1)，0.1Dm(n-1)]Namely, the up-down fluctuation of the average difference of the path lengths of the current patrol compared with the average difference of the path lengths of the last patrol is not more than 10%. In other embodiments, the floating values may be set to 5%, 15%, or other values.
In some embodiments, the method further comprises the steps of:
G. and calculating the average difference of the path lengths of the patrolling personnel from 2 nd to m th. In the step, the steps B-D can be repeated to calculate the average difference value of the path lengths of the patrolling of the 2 nd to the mth patrollers.
H. And calculating the average value of the average difference values of the path lengths of the m inspectors during the current inspection according to the average difference values of the path lengths of the 1 st to m inspectors during the current inspection. The calculation formula of the average value of the average difference values of the routing inspection path lengths is as follows:
Tmn＝(D1n+D2n+…+Dmn)/m；
Tmnaverage of the average differences in path length for the nth inspection of m inspectors, DmnAnd the average difference value of the nth inspection of the mth inspector is m, and m is the number of the inspectors. In a real situation, two or more polling personnel can carry out shift polling on one polling route. Therefore, the average value of the average difference values of the path lengths of a plurality of inspectors who inspect at a certain time (or a certain day) is calculated, and the condition of the inspectors of the inspection route can be reflected on the whole. T ismnThe calculation principle of (D) can be referred tomn(ii) a Theoretically, the positions of the mobile phone and the attendance point of each inspector are fixed, so that the influence factors of GPS positioning of each inspector are fixed and invariable, and theoretically D ismnIs constant, therefore TmnThe system is also a fixed value under ideal conditions, so that if a certain inspector deviates from an inspection route, illegal attendance checking is carried out, the average difference value of the path lengths of the inspection is greatly changed, and T can be causedmnAlso changes, so long as T is detectedmnThe condition that whether the inspection person on the inspection route has attendance abnormity can be known. In addition, in some embodiments, after the attendance of the inspector is judged to be abnormal, the method further comprises the step of rejecting the current attendance data, so that the current abnormal data are prevented from influencing the next attendance calculation.
I. And subtracting the average value of the average difference values of the path lengths of the m inspectors which are inspected at this time from the average value of the average difference values of the path lengths of the m inspectors which are inspected last time to obtain a second difference value.
J. Judging whether the second difference value belongs to a second set numerical range, if so, judging that the current inspection state of the m inspectors is normal, otherwise, judging that the current inspection state of the m inspectors is normalThe state is abnormal. In some embodiments, the second range of values is: [ -0.1Tm(n-1)，0.1Tm(n-1)]That is, the average value of the average difference values of the path lengths patrolled by the m patrollers at this time is compared with the average value of the average difference values of the path lengths patrolled by the m patrollers at the last time, and the condition that the up-and-down fluctuation is not more than 10% is considered to be normal. In other embodiments, the values floating up and down may be set to 5%, 15%, or other values. The steps G-J are added to reflect the problem of the routing inspection route on the whole, and the steps A-F are matched to judge whether the routing inspection personnel on the routing inspection route normally inspect or not from different dimensions, so that the judgment is more accurate.
In some embodiments, further comprising the steps of:
K. and determining standard GPS positioning data of attendance points in the routing inspection route.
And L, calculating the distance between the first inspector and the actual position of the attendance point when the first inspector scans the two-dimensional code according to the standard GPS positioning data and the GPS data of the first inspector, judging that the current inspection state of the first inspector is normal if the distance belongs to a third set value range, and otherwise, judging that the current inspection state of the first inspector is abnormal. This embodiment is through the GPS location data of confirming the attendance point to calculate these data and the first patroller GPS location data that produce when sweeping the code attendance, can confirm whether the position when first patroller sweeps the code attendance is in the third set value scope. The third setting value range can be flexibly adjusted according to actual conditions, such as 0-50 m, 0-100 m and the like.
In some embodiments, the steps K-L, G-J, and C-F may be executed after the step B in parallel, as shown in fig. 2, and the property manager may perform comprehensive judgment on the inspection condition of the inspector by combining the judgment results of one or more of the steps L, J and F.
The step numbers in the embodiment are provided only for convenience of illustration, the order between the steps without illustrating the order relationship is not limited at all, and the execution order of each step in the embodiment can be adaptively adjusted according to the understanding of those skilled in the art.
The invention has the following advantages:
