Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and specifically to a navigation route sharing method and system based on blockchain geographic information. Background Art

[0002] Delivery delays due to temporary roadblocks or poor road conditions are common, and delivery platforms can be penalized for these delays. Due to the tight timelines and high workloads inherent in the delivery industry, and for safety reasons, drivers cannot always monitor group chat messages. Therefore, a crowdsourced sharing method for temporary roadblock information is needed to provide riders with real-time updates on temporary roadblock information posted by other riders. Furthermore, riders who have already been delayed due to roadblocks can provide this information as supporting evidence to reduce deductions in subsequent delivery fee calculations. To encourage the posting of roadblock information, incentives and delivery fee deductions can be implemented. However, due to the frequent fluctuations in temporary roadblocks, the actual impact on riders varies. Therefore, the timeliness and authenticity of roadblock information should be properly assessed to avoid uniformity in incentives, exemptions, and adjustments to delivery fee deductions. Summary of the Invention

[0003] The purpose of this invention is to solve the above technical problems and provide a navigation route sharing method based on blockchain geographic information.

[0004] Another object of the present invention is to provide a navigation route sharing system based on blockchain geographic information.

[0005] The purpose of the present invention can be achieved by taking the following technical solutions:

[0006] The system's delivery end obtains and uploads the roadblock location and roadblock image of the rider who encounters the roadblock for the first time; the roadblock image is reviewed by the smart contract deployed on the blockchain and the roadblock information is synchronized to the riders near the rider who encounters the roadblock for the first time through the navigation function of the delivery end; the delivery end uses the navigation function to re-plan the route for the nearby riders; the delivery platform issues rewards and delayed delivery fee reductions to the first publisher through the merchant end of the system; the merchant end determines whether to give rewards or delayed delivery fee reductions to subsequent publishers based on the authenticity, timeliness and time interval of the subsequently released roadblock information; the merchant end can gradually establish a regional roadblock delay time prediction model based on data accumulation, so as to provide customers with more accurate delay information in the future. Preferably, the roadblock location and roadblock image of the rider who encounters the roadblock for the first time are obtained and uploaded through the system delivery end, including: obtaining the roadblock location of the rider who encounters the roadblock for the first time through the GPS positioning function of the delivery end, and at the same time, the rider who encounters the roadblock for the first time takes a photo of the roadblock image through the delivery end according to regulations, and uploads it to the blockchain synchronously with the roadblock location; the delivery end has the functions of obtaining positioning, uploading images, and voice navigation; the regulations refer to that the roadblock image must include the specific roadblock situation to prove that the roadblock has indeed affected the journey; the regulations also include that the uploaded roadblock images are all collected by the delivery end and have time watermarks, and are automatically added once collected. After uploading, if the roadblock image has double watermarks or no watermarks, that is, the picture was not collected by the delivery end or was collected and reused by others, it is regarded as an invalid roadblock image.

[0007] Preferably, the roadblock image is reviewed by a smart contract deployed on the blockchain and the roadblock information is synchronized to the riders near the rider who encounters the roadblock for the first time through the navigation function of the delivery end, including: when the rider who encounters the roadblock for the first time uploads the roadblock image to the blockchain, it is reviewed by the smart contract as a real roadblock picture, and the smart contract pushes the roadblock image and the roadblock location to the navigation function of the delivery end as the roadblock information; the smart contract has the function of reviewing the roadblock image and pushing the updated roadblock information to the navigation function; the delivery end receives the roadblock information and searches for other riders within 1 kilometer near the rider who encounters the roadblock for the first time. If the other riders have turned on the application, they can be retrieved; the navigation function prompts the nearby riders with the roadblock information through voice.

[0008] Preferably, the delivery end uses the navigation function to re-plan the route for the nearby riders, including: the navigation function re-plans the nearest route for the nearby riders through voice navigation; the planning is started after the nearby riders instruct and will not start automatically.

[0009] Preferably, the delivery platform issues rewards and exemptions for delayed delivery fees to the first publisher through the merchant end of the system, including: the merchant end refers to the docking end between the system and the delivery platform; the first publisher refers to the rider who encounters the roadblock for the first time after the published roadblock information is reviewed by the smart contract; the first publisher can enable the nearby riders to avoid the roadblock. When the delivery platform calculates the delivery fee through the merchant end, if the first publisher does not delay delivery, he will be given a reward of a certain proportion w% of the original delivery fee, that is, the current delivery fee is (1+w%)*original delivery fee; if the first publisher delays delivery due to the roadblock information he uploaded, the original delivery fee will not be deducted.

[0010] Preferably, the merchant side determines whether to give rewards or deductions for delayed delivery fees to subsequent publishers based on the authenticity, timeliness and time interval of the roadblock information subsequently released, including: the subsequent publishers include intraday subsequent publishers and daytime subsequent publishers; the intraday subsequent publisher refers to the roadblock location of a certain roadblock. After the first publisher, there may be multiple riders who fail to change their routes in time and are affected by the same roadblock location. If the roadblock information of the same roadblock location is repeatedly released on the same day as evidence of delayed delivery, they are the intraday subsequent publishers;

[0011] The following measures will be taken against subsequent publishers during the aforementioned days:

[0012] a. Assume that the delivery platform has the following delivery fee deduction standards: Level 1: If the delivery time is 0-x minutes overtime, a% of the delivery fee will be deducted; Level 2: If the delivery time is yz minutes overtime, b% of the delivery fee will be deducted; Level 3: If the delivery time is more than z minutes overtime, c% of the delivery fee will be deducted, where a <b<c<=100,x<y<z;

[0013] b. For subsequent publishers within the day, if the subsequent delivery is indeed overdue, first divide the deduction level according to the delivery fee deduction standard; c. Based on the deduction level, determine the delivery fee deduction range of this time as v%, and the merchant end calculates the time interval t between the time when the subsequent publisher published the roadblock information within the day and the time when the first publisher published the roadblock information with the same roadblock location; d. Count all the time intervals between the time when all riders published the roadblock information with the same roadblock location on that day and the time when the first publisher published it, sort all the time intervals from small to large, and examine the top percentile u of t in the sorting; e. The final degree of delivery fee deduction is: (v% - the previous level delivery fee deduction percentage) * u% + the previous level delivery fee deduction percentage.

[0014] The said intraday subsequent publisher refers to the person who has the first publisher and the intraday subsequent publisher for the roadblock on date A, and then the first publisher of the day for the roadblock is generated on date B, wherein date B > date A.

[0015] The following measures will be taken against the subsequent publishers during the day:

[0016] a. If the subsequent publisher releases the roadblock information before the roadblock, there is a roadblock change information released on Date C, and Date A < Date C < Date B, then the subsequent publisher can obtain the reward and the delayed delivery fee deduction exemption, the rules are the same as the first publisher;

[0017] b. If no roadblock change information is released between Date A and Date B, subsequent publishers during that day will not be eligible for the reward and the delayed delivery fee reduction; subsequent publishers on the day of the roadblock on Date B will also not be eligible for the delayed delivery fee reduction adjustment.

[0018] The roadblock change information refers to the fact that because roadblocks are temporary, they may be removed and even rearranged after removal. Therefore, it is necessary to track their removal information in real time, which is the roadblock change information. The rider who first publishes the roadblock change information for a roadblock on a certain day is the publisher of the roadblock change information.

[0019] The reward rules for the publisher of the roadblock change information are the same as those for the first publisher of the roadblock information, but the publisher does not receive the delayed delivery fee deduction exemption. The reward rules for the subsequent publisher during the day are the same as those for the subsequent publisher, that is, if there is no release of the location roadblock information between the two releases of the roadblock change information, the publisher will not receive the reward. Otherwise, the publisher can receive the reward.

[0020] Preferably, the merchant side can gradually establish a regional roadblock delay time prediction model based on data accumulation to provide customers with more accurate delay information in the future, including: after achieving a certain amount of data accumulation, the delivery platform can collect the rider's delivery delay time and the corresponding roadblock information through the merchant side and blockchain, and after classifying the roadblock information, use the delivery delay time as y and the classification, combined with the public weather, traffic overview, delivery time, rider order volume, holidays and other information of the day as x to establish the roadblock delay time prediction model to predict delivery delay time under various roadblock situations. After the rider subsequently publishes the roadblock information, the merchant side predicts the delay time using the roadblock delay time prediction model, sends text messages to customers, optimizes services, and improves customer stickiness and delivery satisfaction.

[0021] Another object of the present invention can be achieved by adopting the following technical solutions:

[0022] A navigation route sharing method and system based on blockchain geographic information, characterized in that the system includes:

[0023] Merchant side, delivery side, smart contract module;

[0024] The delivery end is deployed on the rider's terminal device and further includes the following modules: an image acquisition module, a GPS positioning module and a voice navigation module; the image acquisition module and the GPS positioning module are used to collect the roadblock image and location and upload them to the blockchain; the voice navigation module is used to provide navigation services for the rider and receive the roadblock information from the blockchain in real time.

[0025] The merchant end is deployed on the delivery platform and managed by the delivery platform company, and further includes the following modules: a roadblock repeatability review module, a delivery fee calculation module and a delay time prediction module; the roadblock repeatability review module is used to review the time and repeatability of the roadblock information and the roadblock change information, so as to determine whether to issue rewards to the first publisher, the subsequent publisher during the day and the publisher of the roadblock change information; in addition to providing the rewards or the delayed delivery fee deduction exemption to the above three types of publishers that have passed the review of the roadblock repeatability review module, the delivery fee calculation module is also used to provide the delayed delivery fee deduction adjustment for the subsequent publishers within the day, and calculate the total delivery fee according to the wage cycle; after accumulating a certain amount of data for the delivery platform, the delay time prediction module can establish the roadblock delay time prediction model through the roadblock information and the actual delay of the rider, so that after classifying the roadblock information in the later stage, it can be combined with other influencing variables of the day to accurately provide customers with the delay time range and send it in the form of text messages.

[0026] The smart contract module is deployed on the blockchain and is used to preliminarily review the watermark status of the roadblock images uploaded to the blockchain and eliminate images with double watermarks and no watermarks. At the same time, the smart contract module updates the roadblock information to the voice navigation module based on the roadblock information that has passed the review, retrieves the roadblock to locate nearby riders, and pushes messages to start re-routing and voice navigation services. If the nearby rider chooses to use the service, the voice navigation module starts working.

[0027] The beneficial effects of this application include: designing a method and system that combines image information collection, GPS technology, voice navigation technology, and blockchain technology to enable riders to update and upload roadblock information in real time; rewarding riders based on the timeliness and authenticity of the information, and exempting delivery fees from deductions due to roadblock delays. In further development, merchants can use the accumulated raw data to provide customers with more accurate delay information within the delivery timeframe. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 This is a flow chart of a navigation route sharing method based on blockchain geographic information provided in an embodiment of the present application.

[0029] Figure 2 This is a schematic diagram of a navigation route sharing system based on blockchain geographic information provided in an embodiment of the present application. DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] S1: Obtain and upload the roadblock location and roadblock image of the rider who first encounters the roadblock through the system delivery terminal, including:

[0032] The roadblock location of the rider who encounters the roadblock for the first time is obtained through the GPS positioning function of the delivery end. At the same time, the rider who encounters the roadblock for the first time takes a photo of the roadblock through the delivery end as required and uploads it to the blockchain synchronously with the roadblock location.

[0033] The delivery terminal has the functions of obtaining positioning, uploading images, and voice navigation.

[0034] The regulations state that the roadblock image must include specific roadblock conditions, such as construction site color steel plates, accident isolation belts, road maintenance, etc., to prove that the roadblock has indeed affected the journey; the regulations also include that the uploaded roadblock images are all collected through the delivery end and have time watermarks, and are automatically added once collected. If the roadblock image has two or no time watermarks after uploading, it means that the image was not collected through the delivery end or was collected and reused by others, and it is considered an invalid roadblock image.

[0035] The time watermark will be added to a specific position of the roadblock image, and other text content should be avoided from being included in the specific position during collection.

[0036] S2: Review the roadblock image through a smart contract deployed on the blockchain and synchronize the roadblock information to the riders near the rider who first encountered the roadblock through the navigation function of the delivery terminal, specifically including:

[0037] When a rider encountering a roadblock for the first time uploads an image of the roadblock to the blockchain, the smart contract verifies that it is a genuine image of the roadblock. The smart contract then pushes the image and its location to the navigation function on the delivery side as the roadblock information. The smart contract verifies the roadblock image and pushes updated roadblock information to the navigation function.

[0038] The delivery end receives the roadblock information and searches for other riders within 1 km of the rider who first encountered the roadblock. If the other riders have turned on the application, they can be retrieved; the navigation function prompts the nearby riders with the roadblock information through voice.

[0039] S3: The delivery terminal uses the navigation function to re-plan the route for the nearby rider, specifically including:

[0040] The navigation function re-plans the shortest route for the nearby riders through voice navigation.

[0041] The plan is activated after the nearby riders give their permission and will not start automatically.

[0042] S4: The delivery platform issues rewards and deductions for delayed delivery fees to the first publisher through the merchant side of the system, specifically including:

[0043] The merchant end refers to the end where the system connects to the delivery platform; the first publisher refers to the rider who encounters a roadblock for the first time after the published roadblock information is reviewed and approved by the smart contract.

[0044] The first publisher can enable the nearby riders to avoid the roadblock. When the delivery platform calculates the delivery fee through the merchant side, if the first publisher does not delay delivery, he / she will be given a reward of a certain proportion w% of the original delivery fee, that is, the current delivery fee (1+w%)*original delivery fee; if the first publisher delays delivery due to the roadblock information he / she uploaded, the original delivery fee will not be deducted.

[0045] S5: The merchant determines whether to reward or reduce the delayed delivery fee for subsequent publishers based on the authenticity, timeliness, and time interval of the subsequent roadblock information, including:

[0046] The subsequent publishers include intraday subsequent publishers and daytime subsequent publishers.

[0047] The subsequent publishers within the day refer to the roadblock location of a certain roadblock. After the first publisher, there may be multiple riders who fail to change their routes in time and are affected by the same roadblock location. If the roadblock information of the same roadblock location is repeatedly published within the same day as evidence of delayed delivery, they are the subsequent publishers within the day.

[0048] The following measures will be taken against subsequent publishers during the aforementioned days:

[0049] a. Assume that the delivery platform has the following delivery fee deduction standards: Level 1: If the delivery time is 0-x minutes overtime, a% of the delivery fee will be deducted; Level 2: If the delivery time is yz minutes overtime, b% of the delivery fee will be deducted; Level 3: If the delivery time is more than z minutes overtime, c% of the delivery fee will be deducted, where a <b<c<=100,x<y<z;

[0050] b. For subsequent publishers within the day, if the subsequent delivery is indeed overdue, first divide the deduction level according to the delivery fee deduction standard; c. Based on the deduction level, determine the delivery fee deduction range of this time as v%, and the merchant end calculates the time interval t between the time when the subsequent publisher published the roadblock information within the day and the time when the first publisher published the roadblock information with the same roadblock location; d. Count all the time intervals between the time when all riders published the roadblock information with the same roadblock location on that day and the time when the first publisher published it, sort all the time intervals from small to large, and examine the top percentile u of t in the sorting; e. The final degree of delivery fee deduction is: (v% - the previous level delivery fee deduction percentage) * u% + the previous level delivery fee deduction percentage.

[0051] For example, a delivery platform has the following delivery fee deduction criteria: 40% for a 0-6 minute delay, 60% for a 12-18 minute delay, and 70% for a 18+ minute delay. If a rider is 16 minutes late, they would be charged 60% of the fee. However, if their roadblock post (not the first one) was 4 minutes after the first post for that location, and the other posting intervals for that location on that day were 5 minutes, 6 minutes, 30 minutes, and 2 minutes, then their posting interval would rank in the top 40% of the total time intervals. Therefore, the delivery fee deduction would be (60% - 40%) * 40% + 40% = 48%.

[0052] The said intraday subsequent publisher refers to the person who has the first publisher and the intraday subsequent publisher for the roadblock on date A, and then the first publisher of the day for the roadblock is generated on date B, wherein date B > date A.

[0053] The following measures will be taken against the subsequent publishers during the day:

[0054] a. If the subsequent publisher releases the roadblock information before the roadblock, there is a roadblock change information released on Date C, and Date A < Date C < Date B, then the subsequent publisher can obtain the reward and the delayed delivery fee deduction exemption, the rules are the same as the first publisher;

[0055] b. If no roadblock change information is released between Date A and Date B, subsequent publishers during that day will not be eligible for the reward and the delayed delivery fee reduction; subsequent publishers on the day of the roadblock on Date B will also not be eligible for the delayed delivery fee reduction adjustment.

[0056] The roadblock change information refers to the fact that because roadblocks are temporary, they may be removed and even rearranged after removal. Therefore, it is necessary to track their removal information in real time, which is the roadblock change information. The rider who first publishes the roadblock change information for a roadblock on a certain day is the publisher of the roadblock change information.

[0057] The reward rules for the publisher of the roadblock change information are the same as those for the first publisher of the roadblock information, but the publisher does not receive the delayed delivery fee deduction exemption. The reward rules for the subsequent publisher during the day are the same as those for the subsequent publisher, that is, if there is no release of the location roadblock information between the two releases of the roadblock change information, the publisher will not receive the reward. Otherwise, the publisher can receive the reward.

[0058] S6: The merchant can gradually establish a regional roadblock delay time prediction model based on accumulated data to provide customers with more accurate delay information in the future, including:

[0059] After accumulating a certain amount of data, the delivery platform can collect riders' delivery delays and corresponding roadblock information through the merchant side and blockchain. After classifying the roadblock information, it uses the delivery delay as y and the classification, combined with publicly available information such as weather, traffic conditions, delivery time, rider order volume, and holidays, as x to establish a roadblock delay prediction model to predict delivery delays under various roadblock scenarios. When riders subsequently publish roadblock information, the merchant side uses the roadblock delay prediction model to predict the delay time and send text messages to customers, optimizing services and improving customer stickiness and delivery satisfaction.

[0060] As an embodiment of the present invention, a navigation route sharing system based on blockchain geographic information includes:

[0061] Merchant side, delivery side, and smart contract module.

[0062] The delivery end is deployed on the rider's terminal device and further includes the following modules: an image acquisition module, a positioning module and a voice navigation module; the image acquisition module and the GPS positioning module are used to collect the roadblock image and positioning and upload them to the blockchain; the voice navigation module is used to provide navigation services for the rider and receive the roadblock information from the blockchain in real time.

[0063] The merchant end is deployed on the delivery platform and managed by the delivery platform company, and further includes the following modules: a roadblock repeatability review module, a delivery fee calculation module and a delay time prediction module; the roadblock repeatability review module is used to review the time and repeatability of the roadblock information and the roadblock change information, so as to determine whether to issue rewards to the first publisher, the subsequent publisher during the day and the publisher of the roadblock change information; in addition to providing the rewards or the delayed delivery fee deduction exemption to the above three types of publishers that have passed the review of the roadblock repeatability review module, the delivery fee calculation module is also used to provide the delayed delivery fee deduction adjustment for the subsequent publishers within the day, and calculate the total delivery fee according to the wage cycle; after accumulating a certain amount of data for the delivery platform, the delay time prediction module can establish the roadblock delay time prediction model through the roadblock information and the actual delay of the rider, so that after classifying the roadblock information in the later stage, it can be combined with other influencing variables of the day to accurately provide customers with the delay time range and send it in the form of text messages.

[0064] The smart contract module is deployed on the blockchain. When the roadblock image is uploaded, it undergoes OCR recognition. The recognition result will extract the time value in the watermark, which will be compared by the smart contract with the upload time of the roadblock image. If there is a double time watermark or no time watermark, or the time value extracted by the OCR review result differs from the upload time of the roadblock image by more than 2 minutes, it will be judged invalid; at the same time, the smart contract module will update the roadblock information to the voice navigation module based on the roadblock information that has passed the review, and retrieve the riders near the roadblock to locate and push messages to start re-routing and voice navigation services. If the nearby riders choose to use the service, the voice navigation module will start working.

[0065] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.

Therefore, it is necessary to track their removal information in real time. This is the roadblock change information. The rider who first publishes the roadblock change information for a roadblock on a certain day is the publisher of the roadblock change information. The reward rules for the publisher of the roadblock change information are the same as those for the first publisher of the roadblock information, but the publisher does not receive the delayed delivery fee deduction exemption. The reward rules for the subsequent publisher during the day are the same as those for the subsequent publisher, that is, if there is no release of the location roadblock information between the two releases of the roadblock change information, the publisher will not receive the reward. Otherwise, the publisher can receive the reward.

8. The method according to claim 2, wherein: The merchant side can gradually establish a regional roadblock delay time prediction model based on accumulated data to provide customers with more accurate delay information in the future, including: After accumulating a certain amount of data, the delivery platform can collect the rider's delivery delay time and the corresponding roadblock information through the merchant side and the blockchain. After classifying the roadblock information, the delivery delay time is taken as y, and the classification is combined with the public weather, traffic overview, delivery time period, rider order volume, and holiday information of the day as x to establish the roadblock delay time prediction model to predict the delivery delay time under various roadblock situations; after the rider subsequently releases the roadblock information, the merchant side predicts the delay time through the roadblock delay time prediction model, sends text messages to customers, optimizes services, and improves customer stickiness and delivery satisfaction.
