Referring to fig. 1, an embodiment of the present invention provides a system for processing abnormal data upload in low communication quality, which includes a self-mobile charging device and a background server which are in communication connection.
Specifically, the self-mobile charging device can receive a charging instruction sent by the background server, charge different charged devices in a set area in an actual scene, and upload charging information after charging to the background server. In addition, the self-mobile charging device can also locally store the data with the uploading abnormality.
Further, the background server can create a charging task, send a charging task instruction to the self-mobile charging equipment, and receive feedback information of the self-mobile charging equipment, and the background server can store all charging information generated by the self-mobile charging equipment.
The self-mobile charging device is configured to perform the steps of:
And S100, acquiring target charging information corresponding to the current charging in response to the completion of the charging of the charged equipment.
Specifically, the target charging information includes a device identifier of the charged device, a device identifier of the self-mobile charging device, a start time and an end time of charging of the charged device.
And S110, the target charging information is sent to a background server.
And S120, if the successful receiving information returned by the background server is not received within the preset waiting time, storing the target charging information into a local memory.
S130, determining whether the current time is within a target time period T= [ T1, T2], if so, setting retransmission time for the target charging information, so that the step S110 is carried out after the retransmission time is reached; the retransmission time is after the target period; t1 is the target start time and T2 is the target end time.
In the embodiment of the present invention, the selectable range of the preset waiting duration is 0.5-5 seconds, and preferably, the preset waiting duration is 2s.
Specifically, the target time period is a time period in which the frequency of the self-mobile charging device receiving the charging task sent by the background server is higher than a preset frequency. And receiving a large number of charging task instructions from the mobile charging equipment in the target time period, and charging the charged equipment, wherein uploading data still possibly causes data uploading failure, so that the target time period needs to be avoided, and the retransmission time is set after the target time period.
Further, the retransmission time may be within 3-10 minutes after the target period, and preferably, the retransmission time is 5 minutes after the target period.
The target time period is determined by the background server executing the following steps before the step S100:
S200, acquiring a first task receiving times set CS1＝(CS1 1,CS1 2,…,CS1 i,…,CS1 n),i＝1,2,…,n;n corresponding to a first time window of the self-mobile charging equipment as the number of first time periods which are identical in length and are sequentially connected and included in the first time window; CS 1 i is the number of times that the self-mobile charging device receives the charging tasks sent by the background server in the ith first time period; the ending time of the first time window is the ending time of the last working day before the current time.
In an embodiment of the invention, the length of the first time window is 24 hours, i.e. from 0 point to 24 points of the last working day before the current time.
S210, a first target value k=1 is acquired.

In the embodiment of the invention, the length of the target time period is not determined, and the number of the first time periods contained in the first target times N1 and the second target times N2 is relatively large, so that the starting time and the ending time of the determined target time period are not accurate enough, and therefore, the three first time periods which are sequentially connected are used as a group of statistical scales, and the sum of the times of charging tasks sent by the background server in each two adjacent groups is calculated. k=1 means that statistics are taken from a first time period within a first time window, i.e. N1 and N2 are acquired, to obtain a first frequency fluctuation P1. If P1 is greater than the first preset threshold Y1, which indicates that the number of times of receiving the charging tasks sent by the background server from the mobile charging device in the corresponding sequentially connected first time periods gradually increases, determining the start time of the first time period corresponding to CS 1 k as the start time of the target time period.
Specifically, Y1 is not less than 1, preferably y1=1.
S240, a second target value j=1 is acquired.
S250, if k+j is less than or equal to N-3, acquiring second frequency fluctuation P2=N4/N3; wherein N3 is a third target number of times, n3=cs 2 k+j+CS2 k+j+1+CS2 k+j+2; n4 is the fourth target number, n4=cs 2 k+j+1+CS2 k+j+2+CS2 k+j+3.

S270, k=k+j is acquired, and the process proceeds to step S220.
In the embodiment of the present invention, by setting the second target value so that the executing step enters the loop, the growth conditions of P1 and P2 are successively determined, and if both P1 and P2 are not smaller than the first preset threshold, it is indicated that the first task reception number of the self-mobile charging device is always increasing until P1 is greater than or equal to Y1, and P2 < Y1 indicates that the first task reception number of the self-mobile charging device starts decreasing, so that the end time of the first time period corresponding to CS 1 k+j+3 can be determined as the end time of the target time period.
It should be noted that, as will be appreciated by those skilled in the art, the number of the determined target time periods may be plural by performing steps S200 to S270. In the present embodiment, explanation is given by taking only an example having one target period. It should be appreciated by those skilled in the art that the method for obtaining the multiple target time periods and the usage method for the multiple target time periods can be known through the technical solutions disclosed in the present embodiment.
The invention provides a data uploading exception handling system under low communication quality, which comprises self-mobile charging equipment and a background server which are connected in a communication way, wherein after the charging of the charged equipment is completed, target charging information corresponding to the current charging can be obtained, then the target charging information is sent to the background server, if receiving success information returned by the background server is not received within a preset waiting time, the target charging information is stored in a local memory, whether the current time is within a target time period T= [ T1, T2] is determined, if yes, retransmission time is set for the target charging information, after the retransmission time is reached, the returned success information which is not received within the preset waiting time is uploaded again, and the data uploading exception is indicated. The data uploading exception handling system under low communication quality provided by the invention can effectively handle the problem of data uploading exception.
In one exemplary embodiment of the invention, the first period of time is of length TM; before the step S200, the background server is further configured to perform the following steps:
S300, a first charging time set CS= (CS 1,CS2,…,CSr,…,CSm) and a first charging duration set SC= (SC 1,SC2,…,SCr,…,SCm) corresponding to the self-mobile charging equipment are obtained; wherein r=1, 2, …, m; m is a preset first target number of days; CS r is the number of times the self-mobile charging device performs a charging task on the r-th workday before the current time; SC r is the total time spent by the self-mobile charging device performing the charging task on the r-th workday before the current time.
And S310, acquiring TM= Σ m k＝1SCk/∑m k＝1CSk according to CS and SC.
Specifically, according to the ratio of the total time consumption of executing the charging task in all working days before the current time to the number of times of executing the charging task in all working days before the current time in the historical data, the average time consumption of executing the charging task each time is obtained. Since the time consumed by the self-moving charging device to perform each charging task for different charged devices may be different, by calculating the average time consumed by each performing charging task, the length of the first time period may be quickly determined with less computing resources consumed.
In an exemplary embodiment of the invention, the first time window is 24 hours in length.
After step S270, the background server performs the following steps each time a set time is reached:
S400, acquiring a historical task receiving times list set LS＝(LS1,LS2,…,LSx,…,LSy);LSx＝(LSx,1,LSx,2,…,LSx,i,…,LSx,n);x＝1,2,…,y;, wherein y is a preset second target number of days; LS x is a historical task receiving times list corresponding to the x-th working day before the set time of the self-mobile charging equipment; LS x,i is the number of times the charging task sent by the background server is received from the mobile charging device in the ith first time period in the xth workday before the set time.
S410, a third target value q=1 is acquired.
S420, if q is less than y, entering step S430; otherwise, the current flow is ended.
S430, obtaining a target difference cy=sqrt (Σ n i＝1(LSq,i-LSq+1,i)2); sqrt () is a preset square root determination function.
S440, if CY < Y2, q=q+1 is obtained, and step S420 is entered; otherwise, go to step S450; y2 is a second preset threshold.
S450, obtaining tm= (w1+w2×hsc)/(w1×qls+w2×hls), and entering step S200 according to the current TM to update T; wherein w1 is a first weight, and w2 is a second weight; qsc= Σ q x＝1LSCx;HSC＝∑y x＝q+1LSCx;LSCx is the total time taken for the self-moving charging device to perform the charging task on the x-th workday before the set time; qls= Σ q x＝1sum(LSx);HLS＝∑y x＝q+1sum(LSx); sum () is a preset summation formula.
Specifically, the preset second target day y may be selected in the range of 5 to 30 days, preferably, y=10.
It should be noted that, in the actual application scenario, the starting time and the ending time of the target time period may be changed due to the modification of the user characteristics such as the user group and the user habit, and the retransmission time needs to be reset. The method comprises the steps of comparing the number of times that a charging task sent by a background server is received in each first time period in a working day before a set time of a mobile charging device with the number of times that the charging task sent by the background server is received in each first time period in the working day before the set time of the mobile charging device, so as to obtain corresponding target difference degree, judging whether a user characteristic is changed or not, judging whether the target time period is changed or not, and if so, recalculating the first time period.
Further, in general, the user features are only partially changed, when the length of the first time period is calculated, all data in the time history of application, including total time spent by the self-mobile charging device executing the charging task and the number of times of executing the charging task before and after the user features are changed, but the degree of influence of the changed user features on the calculation result of the first time period is inconsistent with the degree of influence of the changed user features on the calculation result of the first time period, so that the total time spent by the self-mobile charging device executing the charging task and the number of times of executing the charging task before and after the user features are weighted respectively, and then the length of the first time period is recalculated, so that the calculation result of the length of the first time period is more accurate.
In an exemplary embodiment of the invention, the set time is zero for each weekday.
In an exemplary embodiment of the present invention, the preset second threshold Y2 has a value in the range of [0.01-0.5].
In one exemplary embodiment of the invention, w1=cw1/q; w2=cw2/(y-q); wherein CW1 is a first coefficient, CW2 is a second coefficient, CW1 is greater than or equal to CW2; cw1+cw2=1.
Specifically, the degree of influence of the user features after modification on the calculation result of the first time period is greater than the degree of influence of the user features before modification on the calculation result of the first time period, so that when the length of the first time period is calculated, the total time consumption and the number of times of executing the charging task after modification should be greater than the weight occupied before modification, thereby increasing the accuracy of the calculation result.
In an exemplary embodiment of the present invention, the step S130 includes:
S131, determining whether the current time is within the target time period t= [ T1, T2], if so, acquiring an intermediate set time T' =t2+Δt; delta T is a preset time variation.
S132, determining whether T' exceeds the ending time of the current working day, if so, setting the retransmission information of the target charging information to be 30 minutes before the ending of the current working day, so that the step S110 is entered after the retransmission time is reached; otherwise, T' is set as the retransmission time of the target charging information so that step S110 is entered after the retransmission time is reached.
Specifically, the target charging information of each working day needs to be uploaded before the ending time of the day, and in an actual application scene, a fixed retransmission time can be set to reach the fixed retransmission time, and whether the target charging information is in a target time period or not, the data with abnormal uploading needs to be retransmitted.
In an exemplary embodiment of the present invention, the preset time variation Δt ranges from 0.25 hours to 1 hour.
In an exemplary embodiment of the present invention, after the step S220, the method may further include:
s221, if P1 < Y1, k=k+1 is acquired, and the process proceeds to step S220.
Specifically, if P1 < Y1, it indicates that the number of times of receiving the charging tasks sent by the background server from the mobile charging device in the corresponding first time period connected in sequence is not gradually increased, and it is necessary to re-determine the start time of the target time period.
While certain specific embodiments of the invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the invention. Those skilled in the art will also appreciate that many modifications may be made to the embodiments without departing from the scope and spirit of the invention.
