Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and apparatus for adjusting card swiping time of an IC card.
Background
The public transport passenger flow OD (Original Destination, starting point and destination point) in intelligent transportation is essential basic data for optimally designing a line network and allocating vehicles for an urban public transport system. The analysis of the OD of the bus passenger flow is mainly realized by analyzing card data of a bus IC (Integrated Circuit ) and arrival/departure data, and the number of passengers on a bus station can be finally determined by matching the card swiping time recorded in the card data of the bus IC into the arrival/departure time interval of the vehicle.
However, since the arrival data, departure data, and bus IC card data of the bus are generated by different devices, there may be cases where the arrival data time, departure data time, and time of the IC card device are not synchronized, thereby making the number of guests at the bus stop inaccurate.

According to one aspect of the exemplary embodiments, there is provided a method of adjusting a card swiping time of an IC card, the method including:
determining the departure time of a first station and the arrival time of a last station from the arrival time and the departure time of a vehicle corresponding to the IC card swiping time;

adjusting the adjusted IC card swiping time for N times according to a first preset duration, and determining the probability of the adjusted IC card swiping time each time between the arrival time and the departure time of each station, wherein the adjustment times N are positive integers determined according to the first preset duration, the arrival time of the last station and the maximum card swiping time in the adjusted IC card swiping time;
And taking the IC card swiping time corresponding to the largest probability in the probabilities as the target IC card swiping time.
The method comprises the steps of firstly determining the arrival time of a first station and the arrival time of a last station from the arrival time and the arrival time of vehicles corresponding to the IC card swiping time, then adjusting the IC card swiping time according to the time difference between the minimum card swiping time and the arrival time of the first station in the IC card swiping time so that the minimum card swiping time coincides with the arrival time of the first station, then adjusting the adjusted IC card swiping time for N times according to a first preset duration, determining the probability of the IC card swiping time after each adjustment between the arrival time and the arrival time of each station, and finally taking the IC card swiping time corresponding to the maximum probability in the determined probability as a target IC card swiping time. The IC card swiping time with the highest probability in the probability of the adjusted IC card swiping time between the arrival time and the departure time of each station is used as the target IC card swiping time in the first preset time, so that the IC card swiping time outside the arrival time and the departure time can be matched between the arrival time and the departure time, and the boarding number of each bus station can be counted more accurately through the target IC card swiping time.
In one possible implementation manner, before determining the departure time of the first station and the arrival time of the last station, the method further includes:

if the departure time in the time period is missing, supplementing the missing departure time according to the arrival time of the vehicle.
In order to make the card swiping time of the determined target IC card more accurate, the method should ensure the integrity of the arrival time and the departure time, and if the arrival time and/or the departure time are/is missing, the missing data needs to be supplemented.
In one possible implementation manner, the supplementing the missing arrival time according to the departure time of the vehicle includes:

if the arrival time of the first station is not lost when the vehicle runs for the first time, taking the maximum departure time of the last station when the vehicle runs for the last time as the arrival time of the first station which is lost;
if the arrival time of the vehicle at the non-first station is missing, taking the maximum departure time of the last station as the missing non-first station arrival time, wherein the maximum departure time is the maximum departure time of the vehicle shift corresponding to the missing arrival time in a third preset duration;
the supplementing the missing departure time according to the arrival time of the vehicle comprises the following steps:
if the departure time of the last station of the vehicle is missing, taking the time of a fourth preset duration after the arrival time of the last station as the missing departure time of the last station;
And if the departure time of the non-terminal station of the vehicle is missing, taking the minimum arrival time of the next station as the missing departure time of the terminal station, wherein the minimum arrival time is the minimum arrival time of the vehicle shift corresponding to the missing departure time in a fifth preset duration.
The method provides a method for supplementing missing arrival time and missing departure time, and the method can enable the determined card swiping time of the target IC card to be more accurate.
In one possible implementation, the adjustment number N is determined by:
and taking the quotient of the difference value of the arrival time of the last station and the maximum card swiping time and the first preset duration as the adjustment times N.

At present, the number of people on a bus stop can be determined by analyzing the card reading records of the IC card, under normal conditions, the number of the IC card reading data of the IC card between the arrival time and the departure time of the bus stop is the number of people on the bus stop, however, some people on the bus stop may exist, but the card reading time of the IC card is possibly after the departure time and possibly after the arrival time of the next station, therefore, the number of the IC card reading data of the IC card between the arrival time and the departure time of the bus stop is not accurate.
In view of the above, the present application provides a method for adjusting IC card swiping time, by which IC card swiping time can be adjusted according to a time difference between a minimum card swiping time and an arrival time at a head station among IC card swiping times, and finally a target IC card swiping time is determined according to a probability of each adjusted IC card swiping time between an arrival time and an arrival time at a station, so that a boarding number of a bus station is determined according to the target IC card swiping time, instead of simply determining a boarding number of a bus station according to an actual IC card swiping time, thereby improving accuracy of counting boarding numbers of each bus station.
As shown in fig. 2, a method for adjusting card swiping time of an IC card according to an embodiment of the present invention includes:
s201, determining the departure time of a first station and the arrival time of a last station from the arrival time and the departure time of the vehicle corresponding to the IC card swiping time.
In implementation, before determining the departure time of the first station and the arrival time of the last station, vehicle information corresponding to the IC card data may be determined according to the IC card swiping data corresponding to the IC card swiping time, and then the arrival time and the departure time of the vehicle corresponding to the vehicle information in the period of the IC card swiping time may be acquired.
The IC card data here may be the serial number of the card reader.
For example, the card swiping time of the IC card is 10 points 00 minutes in 1 month and 12 days in 2020, the number of the card swiping machine corresponding to the time is a, and the vehicle information corresponding to the number a of the card swiping machine is determined by searching the corresponding relation between the number of the card swiping machine and the vehicle information, wherein the vehicle information can be the license plate number of the vehicle.
And acquiring the arrival time and the departure time of the vehicle in the time period of the IC card swiping time corresponding to the vehicle information, wherein the arrival time and the departure time are the arrival time and the departure time of the vehicle at each bus station.
For example, if the IC card swiping time is from 8:00 in the year 2020, 1:12:17 in the year 2020, the arrival time and departure time of the vehicle at each station in the time period corresponding to the vehicle information are acquired.
After the arrival time and the departure time of the vehicle in the time period of the IC card swiping time corresponding to the vehicle information are acquired, because there may be a missing of the acquired arrival time and departure time data, it is necessary to determine whether the arrival time and/or the departure time has a missing phenomenon, and if the missing phenomenon exists, it is necessary to supplement the missing data.
Specifically, whether the phenomenon of missing of the arrival time and/or the departure time exists or not is judged, whether the arrival time and the departure time of each bus station exist or not is only needed to be analyzed, if one of the arrival time and the departure time does not exist, the phenomenon of missing data is indicated, and missing data needs to be supplemented.
In supplementing missing data, there are two cases, a missing arrival time and a missing departure time. The missing arrival time is supplemented, and the missing arrival time can be supplemented according to the departure time of the vehicle; the missing arrival time is supplemented, and the supplement can be performed according to the arrival time of the vehicle.
The arrival time of the supplementary missing and the departure time of the supplementary missing will be described below, respectively.
1. The missing arrival times are complemented.
The absence of arrival time includes three different cases, which are respectively described below.
1. If the arrival time of the first station is lost when the vehicle runs for the first time, taking the time of the second preset duration before the departure time of the first station as the arrival time of the lost first station.
The second preset time period here may be set empirically, such as 15 minutes.
Because the bus driver can open passengers such as a car door and the like for a period of time before getting off, the passengers can possibly swipe cards after getting on, so that the time before the second preset time length of the departure time of the first station can be used as the missing arrival time of the first station in order to match the IC card swiping time with the arrival time and the departure time of the first station more accurately.
2. If the arrival time of the first station is not lost when the vehicle runs for the first time, the maximum departure time of the last station in the last running process can be used as the arrival time of the first station which is lost.
The maximum departure time is the maximum departure time of the vehicle shift corresponding to the missing departure time in the third preset time.
For example, the vehicle a is to run three times a day, namely, the vehicle shift 1, the vehicle shift 2 and the vehicle shift 3, and the statistics is that the departure time of the vehicle a at the bus station a is 5 in total when the vehicle a runs the vehicle shift 1 in the last 5 days, namely, 10:00, 10:01, 10:02, 10:00, 10:01, the maximum time 10:02 is selected from the 5 times as the maximum departure time of the vehicle a at the bus station A in the shift 1.
The third preset time period may be set according to actual needs.
3. If the arrival time of the non-head station of the vehicle is missing, the maximum departure time of the last station can be taken as the arrival time of the missing non-head station.
For example, the route passed by the vehicle a includes a bus stop a and a bus stop B, the bus stop a is the last stop of the bus stop B, when the card swiping time of the target IC card is determined, the arrival time of the bus stop B is determined to be missing, and the maximum departure time of the bus stop a in the vehicle shift corresponding to the arrival time missing in the bus stop B in the preset time period can be used as the arrival time of the bus stop B.
2. Make up for missing departure time.
The absence of departure time includes two different cases, which are respectively described below.
1. If the departure time of the terminal station of the vehicle is missing, taking the time of a fourth preset time length after the arrival time of the terminal station as the departure time of the missing terminal station.
The preset time period can be set according to actual needs, such as 15 minutes. The fourth preset time period is also understood as the rest time of the bus driver.
2. If the departure time of the non-terminal station of the vehicle is missing, the minimum arrival time of the next station can be taken as the departure time of the missing terminal station.
The minimum arrival time here is the minimum arrival time of the shift of the vehicle corresponding to the missing departure time within the fifth preset time period.
For example, the vehicle a is to run three times a day, namely, the vehicle shift 1, the vehicle shift 2 and the vehicle shift 3, and the statistics is that the arrival time at the bus station a is counted in the last 5 days when the vehicle a runs the vehicle shift 1, and the total of 5 arrival times are respectively 10:00, 10:01, 10:02, 10:03, 10:01, the minimum time 10:00 is selected from the 5 times as the minimum departure time of the vehicle a at the bus stop A when the vehicle runs for the shift 1.
S202, adjusting the IC card swiping time according to the time difference between the minimum card swiping time and the departure time of the head station in the IC card swiping time so as to enable the minimum card swiping time to coincide with the departure time of the head station.
For example, the IC card has 5 card swiping times, which are respectively 10:00, 10:08, 10:01, 11:05 and 11:08, and the minimum card swiping time in the 5 card swiping times is 10:00.
The minimum card swiping time in the IC card swiping time coincides with the departure time of the first station, so that the adjusted IC card swiping time is adjusted according to the first preset duration in the next step.
Fig. 3 is a schematic diagram showing that the minimum card swiping time and the departure time of the first station overlap. As can be seen from fig. 3, the departure time of the first station is t0, the arrival time of the last station is t4, the minimum IC card swiping time is t1, the maximum IC card swiping time is t3, the minimum IC card swiping time is adjusted to coincide with the departure time of the first station, that is, the IC card swiping time is moved toward the direction of t0 by a distance of t1-t0, that is, the adjusted IC card swiping time marked in fig. 3.
S203, adjusting the adjusted IC card swiping time for N times according to a first preset duration, and determining the probability of the adjusted IC card swiping time each time between the arrival time and the departure time of each station, wherein the adjustment times N are positive integers determined according to the first preset duration, the arrival time of the terminal station and the maximum card swiping time in the adjusted IC card swiping time.
The first preset duration may be set according to actual needs, for example, 1s.
And adjusting the IC card swiping time after N times of adjustment according to the first preset time length, and combining with FIG. 3, namely moving the adjusted IC card swiping time to the direction of t4, if the first preset time length is 1s, moving the IC card swiping time to the direction of t4 once every 1s, and determining the probability of the IC card swiping time after movement between the arrival time and the departure time of each station.
For ease of understanding, the following description is provided in connection with specific examples.
As shown in fig. 4a, to determine the probability of adjusting the IC card swipe time between the arrival time and the departure time of each station. As can be seen from fig. 4a, there are 3 bus stops, namely bus stop a, bus stop B and bus stop C, wherein the arrival time of bus stop a is t1, the departure time is t2, the arrival time of bus stop B is t3, the departure time is t4, the arrival time of bus stop C is t5, the departure time is t6, the IC card swiping time is 7, namely a, B, C, d, e, f and g, and at this moment, the probability at this moment is 4/7=57.1 when there are 4 IC card swiping times in the arrival time and the departure time.
If the first preset duration is 1s, the adjusted IC card swiping time is moved to the direction of t6 once every 1s, and the probability after movement is calculated. As shown in fig. 4b, after the preset time period is moved for the first time, the number of the IC card swiping times between the arrival time and the departure time of each station is 5, and the probability after the first time movement is 5/7=71.4%.
As shown in fig. 4c, after the preset time period for the second movement, the number of the IC card swiping times between the arrival time and the departure time of each station is 6, and the probability after the second movement is 6/7=85.7%.
After adjusting for N times, determining the probability obtained after each adjustment, where the adjustment times N may be determined according to a first preset duration, the arrival time of the last station, and the maximum card swiping time in the adjusted IC card swiping times, and N is a positive integer.
Specifically, the quotient of the difference value of the arrival time of the last station and the maximum card swiping time and the first preset duration is taken as the adjustment times N.
For example, the arrival time of the last station is 10:00, the maximum card swiping time is 9:50, the first preset time length is 1s, N is 10:00-9:50=10 min (minutes), the 10min corresponds to 600s, and n=600/1=600, i.e. the adjustment times are 600 times.
S204, taking the IC card swiping time corresponding to the largest probability in the probabilities as the target IC card swiping time.
The probability after each adjustment is determined, the IC card swiping time corresponding to the maximum probability is selected from the determined probabilities after each adjustment, namely the number of the IC card swiping time falling between the arrival time and the departure time of each station is the maximum, and the IC card swiping time corresponding to the maximum probability in the probabilities is taken as the target IC card swiping time.
For example, in fig. 4B, the probability after the first adjustment is 71.4%, in fig. 4C, the probability after the second adjustment is 85.7%, and the maximum probability is 85.7%, as can be seen from fig. 4C, at this time, the IC card swiping time between the arrival time and the departure time of the a station is 1, the IC card swiping time between the arrival time and the departure time of the B station is 3, and the IC card swiping time between the arrival time and the departure time of the C station is 2, then it can be seen from fig. 4C that 1 person is on the a station, 3 persons are on the B station, and 2 persons are on the C station.
The passenger number of each bus station can be counted more accurately through the determined target IC card swiping time, so that the method can provide help for optimally designing a line network and allocating vehicles for the urban public transportation system.
