Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0044] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] Combine the following Figure 1-Figure 3 The invention describes a method, device and shared vehicle for automatically identifying a damaged QR code provided by an embodiment of the invention.

[0046] Figure 1 It is a flow chart of the method for automatically identifying the contaminated QR code provided by the present invention, which is set up in the remote background to realize the management platform for the joint operation and management of all shared vehicles, such as Figure 1 As shown, including but not limited to the following steps:

[0047] Step 11: receiving light intensity information reported by the target vehicle, wherein the light intensity information is collected by a photosensitive device disposed on the back of the QR code on the target vehicle.

[0048] The target vehicle refers to any shared vehicle put on the market. The type of shared vehicles may be bicycles, motorcycles, electric vehicles, motor vehicles, etc., which are not specifically limited in the present invention.

[0049] A photosensitive device is pre-installed on the back (also called the base) of the QR code of each shared vehicle. At the same time, when designing and installing the QR code, some space can be left in the middle of the code to allow light to pass through the leftover space and enter the photosensitive part of the photosensitive device. The photosensitive device can generate corresponding light intensity information based on the strength, weakness, amount, or quantity of light received by its photosensitive part.

[0050] Generally speaking, when a QR code is stained, the space in the middle part will change to a certain extent, which will affect the state of light entering the photosensitive part of the photosensitive device. For example, if the QR code is covered by stains, the light cannot enter the photosensitive part of the photosensitive device through the space in the middle part, and the light intensity information detected by the photosensitive device reflects a decrease in light intensity.

[0051] The photosensitive device is connected to the vehicle electronic control unit (ECU) to upload the detected light intensity information to the vehicle ECU in real time, and then the vehicle ECU packages the light intensity information and reports it to the management platform at a preset frequency.

[0052] Step 12: Determine the contamination status of the QR code on the target vehicle according to the light intensity information and the light intensity reference value.

[0053] After receiving the light intensity information uploaded by each shared vehicle within its management area, the management platform can compare the light intensity information uploaded by any target vehicle with a predetermined light intensity reference value to determine the contamination status of the QR code on the target vehicle based on the comparison result. Even after determining that the QR code of the target vehicle is contaminated, it can also preliminarily determine the type of contamination that has occurred, including damage, being covered by pollutants, etc.

[0054] For example: by comparing the light intensity information of the target vehicle within half an hour, if the difference between the light intensity information and the light intensity reference value is greater than the first threshold, it can be determined that the light intensity information is abnormal, and it can be judged that the light cannot pass through the QR code of the target vehicle to enter the photosensitive device thereon, so it can be determined that the defacement state of the QR code of the target vehicle is a defaced state.

[0055] Among them, the light intensity reference value can be predetermined according to the weather conditions when the light intensity information is collected, or it can be determined according to the average value of the light intensity information of multiple other shared vehicles within a certain range of the target vehicle area. The present invention does not make specific limitations on this.

[0056] The automatic identification method for QR code contamination provided by the present invention can determine that the QR code of a target vehicle with abnormal light intensity information is contaminated by automatically collecting and analyzing the light intensity information of the QR code on any target vehicle. It has a high degree of automation and can effectively improve the accuracy of inspection and monitoring of QR code contamination, and greatly reduces the investment in manpower and material resources, thereby reducing the operating costs of the company to which the shared vehicles belong.

[0057] Based on the content of the above embodiment, as an optional embodiment, before determining the defacement state of the two-dimensional code on the target vehicle based on the light intensity information and the light intensity reference value, the method further includes:

[0058] Determining the current position information of the target vehicle;

[0059] Acquire light intensity information reported by multiple other vehicles within a first preset range with the current location information as the center;

[0060] An average value of the light intensity information reported by the plurality of other vehicles is calculated to determine the light intensity reference value.

[0061] The invention provides a method for determining a light intensity reference value according to current position information of a target vehicle.

[0062] First, the management platform can receive in real time the current location information reported by the on-board ECU of each shared vehicle within its management range.

[0063] When it is necessary to detect the defacement status of the QR code of any target vehicle, firstly, based on the current position information of the target vehicle, it is determined whether there are other vehicles within a first preset range centered on the current position information.

[0064] The first preset range may be determined according to actual conditions, such as taking a range within a radius of 3 meters as the first preset range.

[0065] Assuming that the management platform can determine that there are three other vehicles within the first preset range of the target vehicle based on the current location information of all shared vehicles, the light intensity information reported by these three other vehicles can be extracted respectively, and recorded as: light intensity information A, light intensity information B, and light intensity information C.

[0066] Furthermore, an average value of the light intensity information A, the light intensity information B, and the light intensity information C is calculated as a reference value of the light intensity of the target vehicle at the current moment.

[0067] It should be noted that the automatic identification method for QR code contamination provided by the present invention, for different target vehicles, when the current location information of the target vehicle is different, the number of other vehicles within its first preset range is different, and the light intensity information reported by other vehicles is different, the determined light intensity reference value will be automatically adjusted so that the determined light intensity reference value can truly and accurately reflect the current light intensity standard of the target vehicle.

[0068] Since the environmental conditions of other vehicles within the first preset range are similar or even the same as those of the target vehicle, and the probability of the same type of QR code being defaced on other vehicles at the same time is extremely small, the accuracy can be greatly improved by calculating the light intensity reference value based on the light intensity information of other vehicles.

[0069] The method for automatically identifying defaced QR codes provided by the present invention can automatically determine a light intensity reference value in real time according to the different environments in which the target vehicle is located and the light intensity information of other vehicles around the target vehicle, thereby providing a reference standard for judging the defacement status of the QR code of the target vehicle, and can effectively improve the accuracy of automatic identification of defaced QR codes.

[0070] Based on the content of the above embodiment, as an optional embodiment, determining the defacement state of the QR code on the target vehicle according to the light intensity information and the light intensity reference value includes:

[0071] Determine a maximum light intensity threshold and a minimum light intensity threshold according to the light intensity reference value to construct a normal light intensity interval;

[0072] If the light intensity information is continuously within the normal light intensity interval within the first time period, determining that the defacement state is an undefacement state;

[0073] If the light intensity information is continuously outside the normal light intensity interval within the first time period, the defacement state is determined to be a defaced state.

[0074] The present invention provides a method for determining a contamination state according to light intensity information and a light intensity reference value.

[0075] The first duration may be predetermined, such as half an hour, 40 minutes, 1 hour, etc., and the present invention does not make any specific limitation on this.

[0076] By adopting the method provided in the above embodiment, after determining the light intensity information of a plurality of other vehicles within the first preset range where the target vehicle is located, the corresponding normal light intensity range can be determined.

[0077] Assume that the light intensity reference value is x candela (cd for short), then the maximum light intensity threshold can be set to x+a candela, and the minimum light intensity threshold can be set to xa candela, that is, the normal light intensity range is [xa, x+a].

[0078] Optionally, if the received light intensity information of the target vehicle is greater than x+a candela, or less than xa candela, it can be considered that the defacement state of the QR code of the target vehicle is in a defaced state.

[0079] Correspondingly, if the received light intensity information of the target vehicle is less than or equal to x+a candela and greater than or equal to xa candela, it can be considered that the defacement state of the QR code of the target vehicle is not defaced (ie, normal state).

[0080] It should be noted that the present invention can determine the normal light intensity interval based on historical experience and the light intensity reference value, and can also determine it based on the division of the first preset range where the target vehicle is located.

[0081] For example, for the current QR code contamination status judgment of any target vehicle, the first preset range selected for the first calculation of the light intensity reference value is a radius of 1 meter, the first preset range selected for the second calculation of the light intensity reference value is a radius of 2 meters, the first preset range selected for the third calculation of the light intensity reference value is a radius of 3 meters, the first preset range selected for the fourth calculation of the light intensity reference value is a radius of 4 meters, and the first preset range selected for the nth calculation of the light intensity reference value is a radius of n meters. Then, the maximum value of the light intensity reference value calculated n times is used as the maximum light intensity threshold, and the minimum value thereof is used as the minimum light intensity threshold, to construct a normal light intensity interval.

[0082] After the normal light intensity range is determined, it is determined whether the light intensity information reported by the target vehicle within a first time period (such as 1 hour) is continuously outside the normal light intensity range. If it is continuously in that range, it can be determined that the defacement state is the defaced state.

[0083] When judging the defacement status of the QR code of the target vehicle, the present invention continuously monitors the light intensity information within the first time period in order to eliminate interference from the external environment. For example, if a moving object (such as fallen leaves, pedestrians, vehicle users, etc.) temporarily blocks the QR code, the light intensity collected by the photosensitive device of the target vehicle during the blocking period will be reduced. After the first time period is set, if the first time period is appropriately selected, the influence of these situations on the actual detection results can be effectively avoided.

[0084] Furthermore, if the light intensity information is continuously within the normal light intensity interval within the first time period, it can be clearly determined that the defacement state of the target vehicle's two-dimensional code is an undefaced state.

[0085] The two-dimensional code defacement automatic identification method provided by the present invention can effectively improve the accuracy of judging the defacement status by continuously comparing the light intensity information received within a certain period of time.

[0086] Based on the content of the above embodiment, as an optional embodiment, if the light intensity information is continuously outside the normal light intensity range within the first time period, determining that the defacement state is a defaced state specifically includes:

[0087] If the light intensity information is continuously less than the light intensity minimum threshold value within the first time period, it is determined that the contaminated state is that the QR code on the target vehicle is covered by contaminants;

[0088] If within the first time period, the light intensity information is continuously greater than the maximum light intensity threshold, it is determined that the defaced state is that the QR code on the target vehicle is damaged.

[0089] Optionally, the present invention may further determine the type of the defacement event that occurred on the target vehicle based on the comparison relationship between the light intensity information and the normal light intensity interval calculated in real time.

[0090] For example, if it is determined that the light intensity information is continuously less than the minimum light intensity threshold, it means that the light intensity collected by the photosensitive device is greatly reduced, and it can be considered that the probability of being covered by pollutants is very high.

[0091] Correspondingly, if it is determined that the light intensity information is continuously greater than the minimum light intensity threshold, it means that the light intensity collected by the photosensitive device has increased abnormally, and it can be considered that the QR code of the target vehicle has been damaged, resulting in an increase in the leakage space in the middle part. Therefore, it can be determined that the damaged state is a damaged QR code on the target vehicle.

[0092] The method for automatically identifying QR code defacement provided by the present invention can not only automatically determine the defacement state of the QR code of the target vehicle based on the light intensity information of the target vehicle within a preset time period, but can also further determine the type of defacement, so as to notify and guide the operation and maintenance personnel to repair the relevant QR code in a timely and accurate manner according to the type of defacement, thereby improving the repair efficiency of the operation and maintenance personnel.

[0093] Based on the contents of the above embodiments, as an optional embodiment, the method for automatic identification of damaged QR codes provided by the present invention may also include: determining the system order duration of each vehicle within a second preset range within a second time period according to the current location information of the target vehicle; and calculating the average duration of the system order time of each vehicle to determine the first time period.

[0094] The present invention provides a method for determining the above-mentioned first duration, which is mainly determined based on the system order durations of all vehicles within a certain range where the target vehicle is located.

[0095] Since the QR code is blocked (or the light intensity collected by the photosensitive device is reduced), it often happens during the use of the vehicle by the user. For this reason, the present invention obtains the system order duration of all vehicles within a second preset range (such as an operating sub-area) within a second time period (such as one day), and determines the first duration by calculating the average system order duration of all vehicles. That is, the first duration can characterize the average duration of each use of the shared vehicle by the vehicle user.

[0096] Optionally, a preset value may be added to the average value of the system order duration as the first duration; or a preset multiple of the average value of the system order duration may be used as the first duration.

[0097] For example: the calculated system order duration is 45 minutes. On this basis, the above preset value is set to 10 minutes, then the first duration can be set to 55 minutes; or, the preset multiple is set to 2 times, then the first duration can be set to 90 minutes.

[0098] It should be noted that the first duration provided by the present invention is determined based on the average value of the system order duration, but the actually determined duration can be dynamically adjusted based on statistics of the accuracy of historical recognition results during actual operation.

[0099] Based on the content of the above embodiment, as an optional embodiment, after determining that the defacement state is a defaced state, the method may further include: generating a QR code maintenance work order related to the target vehicle.

[0100] The method for automatically identifying damaged QR codes provided by the present invention enables a management platform to promptly generate a QR code maintenance work order for the target vehicle after determining that the QR code of the target vehicle is damaged based on the light intensity information reported by the target vehicle.

[0101] Optionally, the QR code maintenance work order may indicate the current location information of the target vehicle, the type of damage to the QR code, etc., so as to guide the operation and maintenance personnel to repair the QR code of the target vehicle in a timely manner.

[0102] As an optional embodiment, after generating the QR code maintenance work order, it also includes: continuously acquiring the light intensity information reported by the target vehicle; if within the first time period, the light intensity information continues to be within the normal light intensity range, then the QR code maintenance work order is automatically closed.

[0103] After determining that the QR code of the target vehicle is in a defaced state and generating a QR code maintenance work order for it, the present invention continues to accept the light intensity information continuously uploaded by the target vehicle. If it is found that the light intensity information of the target vehicle is continuously within the normal light intensity range within the first time period, it means that the QR code of the target vehicle has been restored to a normal state (i.e., an undefaced state), and the QR code maintenance work order can be automatically closed. Through this operation, it is possible to automatically supervise and check whether the operation and maintenance personnel have completed the repair work of the QR code of the target vehicle.
