Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular device structures, interfaces, techniques, etc. in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

Fig. 1 shows a schematic flowchart of a method for preventing theft of a shared bicycle according to embodiment 1 of the present invention. As shown in fig. 1, the execution subject of the method may be a server, and the method includes the following steps:

The anti-theft method for the shared bicycle, provided by the embodiment 1 of the invention, comprises the steps of firstly selecting a time range and a position which need to monitor the state value of the shared bicycle, acquiring the state information of the shared bicycle at a set frequency after the time range and the position are selected, judging the possibility that the shared bicycle at the position is stolen in batch in the time range according to the state information of the shared bicycle, and then generating different alarm grades and anti-theft measures according to the possibility, wherein the higher the alarm grade is, the higher the theft probability of the shared bicycle is, the more urgent the anti-theft measures need to be taken, so that the anti-theft measures are more targeted, the anti-theft effect of the shared bicycle is improved, the state information of the shared bicycle does not need to be acquired at any time, and resources are saved.

Preferably, in the specific process of embodiment 1 of the present invention, first, a time range for monitoring the state value of the shared bicycle, that is, a preset time range, needs to be determined. For example, a plurality of time periods in which the shared bicycle is stolen and the damaged event occurs can be obtained by collecting news information, relevant statistical reports, accessing a database and the like, the probability of occurrence of the stolen and damaged event of the shared bicycle in each time period is calculated, and the time period with the occurrence probability exceeding a preset threshold is selected as a preset time range. By the method, the accurate preset time range can be obtained, the anti-theft effect of the shared bicycle is further improved, the state parameters of the shared bicycle do not need to be acquired at any time, and resources are saved. More preferably, the initial time point of the preset time range can be advanced for a certain time, such as half an hour or 1 hour, so that the acquired data are more accurate, and the anti-theft effect of the shared bicycle is better.

In other embodiments, the preset time range may also be determined in the following manner:

acquiring positioning information of a preset position;

By adopting the mode, the preset time range can be determined according to the time of darkness and brightness and the remote degree of the preset position. Specifically, the weather forecast information may be acquired, so as to acquire a dark time point and a bright time point, the dark time point is taken as a first initial time point of a preset time range, and the bright time is taken as a first ending time point of the preset time range, such as a certain geographical location, dark at 7 pm, bright at 5 am, the first initial time point is 7 pm, and the first ending time point is 5 am. And then correcting the first initial time point and the first end time point according to the remote degree of the preset position to form a second initial time point and a second end time point, wherein the remote preset position is larger in corresponding adjustment value, for example, the second initial time point is more front relative to the first initial time point, the second end time point is more rear relative to the first end time point, for example, a more remote place, the second initial time point is 6 pm, the second end time point is 6 am, and thus the final preset time range is from 6 pm to 6 am. In a very busy area, the second initial time point may be later than the first initial time point, for example, 9 pm, and the second end time point may be earlier than the first end time point, for example, 4 am, so that the predetermined time range is from 9 pm to 4 am.

The preset time range is determined by adopting the mode, the process is quick and simple, and the obtained preset time range accords with the principle of the shared bicycle anti-theft method, so that the anti-theft effect of the shared bicycle is further improved.

Before the shared bicycle anti-theft method provided by the embodiment 1 of the invention is adopted, a preset position needs to be determined. There are also various methods for determining the preset position, such as setting a designated parking position of a shared vehicle designated by the government as the preset position, because these positions generally park a large number of shared vehicles within a preset time frame. The method can quickly determine the preset positions, but the preset positions are more because of more designated parking positions, and the shared bicycle state information needing to be monitored and acquired by the anti-theft method is more, so that the better anti-theft effect can be ensured, but more resources are consumed.

In other embodiments, the following method may also be adopted to obtain the preset position: inquiring a database of preset brand shared bicycles to acquire parking position information of all preset brand shared bicycles within the preset time range; then, when the number of the shared vehicles parked at a certain position (the number of the shared vehicles parked is the total number of the shared vehicles of each brand) reaches a preset value, such as 100 or 50, the position is taken as the preset position. The preset positions obtained by the method are the positions which are mainly needed to be monitored, so that the number is proper, the anti-theft effect is good, meanwhile, the preset values can be adjusted according to the resource configuration condition of the specific embodiment, the number of the preset positions is adjusted, and the anti-theft method is more flexible.

In other embodiments, the parking number of the shared bicycle at a certain position can be continuously collected, the average value of the parking number of the shared bicycle at the certain position for a period of time is obtained, and when the average value reaches a preset value, for example, 100 or 50, the position is taken as the preset position, so that the obtained preset position is more accurate, the anti-theft effect of the shared bicycle is further improved, and resources are saved.

After the preset time range and the preset position are determined, the preset acquisition frequency is required to be determined, namely the state value of the shared bicycle is acquired at intervals, the more accurate the interval time is set, the higher the probability that the shared bicycle is stolen is found, the earlier the discovery time is, and therefore the better the anti-theft effect is. In a specific embodiment, an appropriate interval time may be set according to a situation, or the interval time may be dynamically adjusted according to a time point, for example, the closer to an initial time point and an end time point of a preset time range, the longer the interval time is set, for example, the time is collected every half hour, and the farther away from the initial time point and the end time point, the shorter the interval time is set, for example, the time is collected every ten minutes, which not only can ensure a single vehicle sharing anti-theft effect, but also can further save resources.

Preferably, in embodiment 2 of the present invention, all the sharing bicycles at the preset positions are marked, and the total number of the marked sharing bicycles, the positioning data of the sharing bicycles, and the vehicle speed are collected at preset time intervals within a preset time range. Fig. 2 is a schematic flow chart of step 2 in embodiment 2, and as shown in fig. 2, the method includes the following steps:

s201, acquiring a first preset judgment condition, a second preset judgment condition and a third preset judgment condition;

s202, judging whether the state value of the shared bicycle meets a first judgment condition, a second judgment condition and a third judgment condition, if so, evaluating that the batch theft probability of the shared bicycle is low and the alarm level is one level; if any two of the three judgment conditions are met, the probability of batch theft of the shared single vehicles is evaluated to be medium, and the alarm level is two-level; if three judgment conditions are met simultaneously, the probability of batch theft of the shared bicycle is evaluated to be higher, and the alarm level is three levels;

the first judgment condition is as follows: whether the proportion of the current number of the shared bicycles at the preset position to the initial number of the shared bicycles is smaller than a first preset value or not;

the second judgment condition is as follows: whether the number of the shared bicycles with the speed reaching the preset speed threshold value reaches a second preset value or not is judged;

the third judgment condition is as follows: whether the number of the shared bicycles with the same moving track reaches a third preset value or not.

In this embodiment, the initial number of shared vehicles is the number of shared vehicles at the initial time point corresponding to the preset time range. In the embodiment, three judgment conditions are set according to the shared bicycle state value, and the corresponding alarm level is determined according to the number of the judgment conditions met by the current shared bicycle state value. As described in the background, the method for destroying the shared bicycle is mainly to transport the shared bicycle to a large vehicle in batches and then transport the shared bicycle to a place to be abandoned or destroyed. The mode comprises several common characteristics, one characteristic is that a plurality of shared single cars can be carried at one time, so that the number of the shared single cars at the preset position can be greatly reduced; secondly, because the speed of the large vehicle is high, the running speed of a large number of shared single vehicles exceeds a normal range, and an abnormal value is presented; and thirdly, a plurality of shared single vehicles are parked on the cart, so that the traveling paths, namely the moving tracks of the shared single vehicles are the same. When one condition is met, the sharing single vehicle can be in an accidental condition or the collected data is out of order, the sharing single vehicle can not be completely judged to be stolen in batch, but the more the met conditions are, the higher the possibility that the sharing single vehicle is stolen in batch can be shown, so that the probability that the sharing single vehicle is stolen in batch can be evaluated according to the number of the met conditions, and the alarm level can be determined. In a specific embodiment, because the positioning data of the shared bicycle is collected, the moving track of the shared bicycle can be analyzed through the calculation of the server; and the shared bicycle is provided with a vehicle speed sensor, so that the server can acquire the vehicle speed of the shared bicycle. If the speed sensor is not arranged on the shared bicycle, the server can also obtain the moving distance of the shared bicycle in unit time according to the positioning data of the shared bicycle, so that the speed of the shared bicycle is calculated. In another specific embodiment, a camera may be disposed at the preset position, the shared bicycle at the preset position is photographed by the camera, and after the server acquires the photo, the shared bicycle in the photo is identified, so that the total number of the shared bicycles at the preset position can be acquired.

Fig. 3 is a schematic flow chart of step 2 in embodiment 3, and as shown in fig. 3, step 2 specifically includes the following steps:

s210, acquiring the proportion of the current number of the shared bicycles at the preset position to the initial number of the shared bicycles, inquiring a preset first corresponding relation table, and generating a corresponding first score according to the interval where the proportion is located;

s211, acquiring the number of first shared bicycles with the speed reaching a preset speed threshold, inquiring a preset second corresponding relation table, and generating a corresponding second score according to the section where the number of the first shared bicycles is located;

s212, acquiring the number of second shared bicycles with the same moving track, inquiring a preset third corresponding relation table, and generating a corresponding third score according to the interval where the number of the second shared bicycles is located;

s213, reading a preset calculation model, and calculating a total score according to the first score, the second score, the third score and the calculation model, wherein the higher the total score is, the higher the probability that the shared bicycle at a preset position is stolen in batch is represented;

s214, inquiring a preset fourth corresponding relation table, and generating a corresponding alarm grade according to the region where the total score is located, wherein the higher the total score is, the higher the alarm grade is.

The above-described embodiments provide another method for assessing the probability of batch theft of shared bikes. Specifically, in embodiment 3, comprehensive scoring is performed according to a proportion of the current number of the shared vehicles at the preset position to the initial number of the shared vehicles, a first number of the shared vehicles whose speed reaches a preset speed threshold, and a second number of the shared vehicles whose movement trajectories are the same, and the probability that the shared vehicles are stolen in batch is evaluated according to the scoring result. The method specifically quantifies the probability of batch theft of the shared single vehicles, so that the evaluation result is more accurate, and the obtained alarm grade is more consistent with the current condition of the preset position. In a specific embodiment, the calculation model is: the total score is a first score + b second score + c third score, where the sum of a, b, c is 1. The calculation model can evaluate the action size of batch theft of the shared bicycle according to the three conditions, and set and adjust the weights of the first score, the second score and the third score in the total score, namely, the values of a, b and c are adjusted, so that the calculated total score and the alarm grade obtained according to the total score are more accurate and effective.

In a preferred embodiment, the alarm levels include a primary alarm level, a secondary alarm level, and a tertiary alarm level, and step 3 specifically includes:

when the alarm level is first level, generating a first alarm instruction, and sending the first alarm instruction and the preset position to monitoring personnel of a monitoring center to remind the monitoring personnel to determine whether the batch stolen event of the shared bicycle occurs at the preset position;

when the alarm level is in the second level, generating a second alarm instruction, sending the second alarm instruction and the preset position to monitoring personnel of a monitoring center to remind the monitoring personnel to determine whether the batch theft event of the shared bicycle occurs at the preset position, and sending the second alarm instruction to the shared bicycle in an abnormal state to drive an alarm module preset on the shared bicycle to send an audible and visual alarm signal;

and when the alarm level is three levels, sending an alarm request to an alarm system 110, and locking the transport vehicle for transporting the shared bicycle in the abnormal state by adopting a preset method.

In the above preferred embodiment, the shared bicycle in the abnormal state is a shared bicycle not located at a preset position, a shared bicycle with a vehicle speed reaching a preset vehicle speed threshold, and a shared bicycle with the same movement track.

In the specific embodiment, the alarm levels are divided into three levels, and corresponding alarm measures are adopted for each alarm level. When the alarm level is first level, the shared bicycle at the preset position is in a batch stolen state with a certain probability, and at the moment, the most important thing is to determine whether the theft occurs, so that the follow-up steps are carried out in time, therefore, a first alarm instruction needs to be sent to the monitoring personnel, and the monitoring personnel is reminded to take the preset measures to determine whether the batch stolen event of the shared bicycle occurs at the preset position. For example, monitoring personnel can call the monitoring video at the preset position to confirm whether the shared vehicle is stolen by people. Or the monitoring personnel inquires the database and judges whether the shared bicycle in the abnormal state is unlocked or not, because the stealing personnel generally adopt the vehicles to transport the shared bicycle, the vehicles are usually directly carried on the shared bicycle under the condition of not unlocking the vehicles, and therefore if a plurality of vehicles are not unlocked and move at the speed exceeding the vehicle speed threshold value or the running tracks of the vehicles are the same, the shared bicycle batch stealing event can be basically judged.

When the alarm level is the second level, the shared bicycle at the preset position is in a batch stolen state with a high probability, whether the theft happens or not still needs to be determined, and meanwhile, some specific measures are taken to prevent the theft from continuing or prevent the theft from continuing. For example, the second alarm instruction and the preset position may be sent to a monitoring person in a monitoring center to remind the monitoring person to determine whether a batch stolen event of the shared bicycle occurs at the preset position. Meanwhile, the second alarm instruction is sent to the sharing bicycle in the abnormal state to drive an alarm module preset on the sharing bicycle to send out sound and light alarm signals, such as preset alarm voice or alarm voice, so that the alarm module can not only warn a thief that the theft is found, but also inform passers-by that the theft continues to be stolen, and remind the passers-by to give an alarm or take other measures to prevent the theft from continuing to be carried out.

When the alarm level is three levels, the shared bicycle at the preset position is in a batch stolen state with a very high probability, the alarm is not confirmed at the moment, the alarm request is directly sent to the 110 alarm system, the transport vehicle for transporting the shared bicycle in the abnormal state is locked by adopting a preset method, and therefore measures are taken to find the transport vehicle before the vehicle is transported to the target position to be damaged or abandoned. In the specific embodiment, there are various positioning methods for the transportation vehicle, and the following description is briefly made. The specific positioning method is that after the sharing bicycle sends out acousto-optic alarm signals, the alarm information of passers-by is collected, and the transportation vehicle is positioned and tracked according to the alarm information. The other method is that the number and the type of the transport vehicles are estimated according to the total number of the shared vehicles in the abnormal state, then the motion trail of the shared vehicles in the abnormal state is obtained, a geographic information database is inquired according to the motion trail, the possible driving routes of the transport vehicles and at least one intersection through which the transport vehicles pass with high probability are estimated, then the camera records near the intersection are called or the camera at the intersection is controlled to take pictures of the passing vehicles, the pictures are analyzed according to the estimated number and the vehicle types of the transport vehicles, at least one possible target transport vehicle is determined, the target transport vehicle is locked, and therefore the shared vehicles are found before being damaged or abandoned with certain probability, and the anti-theft effect is improved.

Of course, in other embodiments, the corresponding measures may be adjusted according to the setting condition of the alarm level, and the adjustment is within the protection scope of the present invention.

Preferably, as another embodiment of the present invention, on the basis of any of the above embodiments, the method further includes counting the occurrence frequency of batch theft events of the shared bicycle at a preset position every preset first statistical time, calculating a risk level according to the occurrence frequency, and generating and storing a map with a risk level label for downloading by an enterprise terminal or a general user client of the shared bicycle.

In the embodiment, the occurrence frequency of the batch stolen events of the shared bicycle at the preset position is statistically analyzed, a map with danger level marks is obtained for reference of enterprises sharing the bicycle, so that the enterprises can replace places to release the shared bicycle or release the shared bicycle more dispersedly, and users can also replace places to park the shared bicycle, thereby reducing the batch stolen occurrence probability of the shared bicycle.

Preferably, as another embodiment of the present invention, on the basis of any of the above embodiments, the method further includes counting, at every preset second statistical time, a driving route after the transportation vehicle steals the shared bicycle and a target position where the transportation vehicle is ready to damage or abandon the shared bicycle, and then generating and storing a map with the driving route and the target position, so that when a batch theft event of the shared bicycle occurs next time, a shared bicycle enterprise or a police can lock the transportation vehicle and the target position more quickly, and thus find the stolen shared bicycle more quickly.
