With the investment of capital and the increase of users, some problems of shared bicycles have gradually emerged. Due to the lack of corresponding fixed piles, the phenomenon of random parking of shared bicycles is particularly serious, which occupies a large amount of public space roads in the city. Therefore, it is necessary for humans to complete the management of shared bicycles to reduce the phenomenon of random parking of shared bicycles.

The management work includes dispatching operation and management operation. The dispatching operation specifically refers to dispatching the shared bicycles placed in different parking frames to meet the number of shared bicycles placed in all parking frames within a preset range; the arrangement operation specifically refers to arranging the shared bicycles placed in the parking frame to make all the shared bicycles placed in a certain parking frame in an orderly and unified manner.

[0045] To make the objectives, technical solutions and advantages of the present application clearer, the present application is described and explained below in connection with the drawings and embodiments. However, it should be understood by those of ordinary skill in the art that the present application can be implemented without these details. It is obvious for those of ordinary skill in the art that various changes can be made to the embodiments disclosed in the present application, and the universal principles defined in the present application can be applied to other embodiments and application scenarios without deviating from the principles and scope of the present application. Therefore, the present application is not limited to the embodiments shown, but conforms to the broadest scope claimed by the present application.

[0046] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0047] The blockchain is a chain composed of one block after another. Each block contains certain information, and they are connected in a chain according to the time sequence of their respective generation. These chains are saved in all servers, and as long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes, and these nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. Compared with traditional networks, the blockchain has two core features: one is that data is difficult to tamper with, and the other is that it is decentralized and transparent. Based on these three features, the information recorded by the blockchain is more real and reliable, and can help solve the problem of mutual distrust among people.

[0048] Figure 1 is a block diagram of a bicycle management method based on a blockchain provided by the present embodiment. As shown in Figure 1 , a bicycle management method based on a blockchain includes the following steps:

[0049] Step S100, acquiring image information representing the placement of bicycles at each parking frame, wherein each image information includes an actual image and a parking frame number corresponding to the actual image.

[0050] The entire area where the shared bicycles are movable includes a plurality of sub-areas, each sub-area is non-overlapping, and all sub-areas constitute the entire area. Each sub-area corresponds to a staff member, and each staff member is only responsible for the management of shared bicycles in the corresponding sub-area. A fixed number of parking frames are provided in each sub-area, which is an area for storing shared bicycles. The parking frame is generally provided in a place with a large flow of people, such as beside the entrance of a community, beside a subway station, beside a bus station, and beside the entrance of a shopping mall, etc. The place with a large flow of people originally has a camera device to record the actual situation in real time, so as to provide a reference for subsequent possible flow analysis, research or management, etc. The camera device can clearly record the actual situation around the position of the camera device in 360 degrees.

[0051] A parking frame number representing the identity of the parking frame is written inside each parking frame in the entire area. The parking frame number written inside each parking frame is different from each other and unique, and the specific parking frame number is an Arabic numeral. The process of gradually placing shared bicycles in the parking frame is also the process of gradually blocking the parking frame number written inside the parking frame by the shared bicycle.

[0052] The aforementioned actual images are obtained through the originally installed camera devices. The installation position of each camera device is fixed, as is the position of each parking bay. Each camera device has the same shooting program. In this embodiment, all camera devices have parking bays located next to them. Here, we will use one camera device as an example to illustrate how the aforementioned image information is obtained. This camera device has at least one parking bay next to it. The camera device rotates at fixed angles according to the shooting program to complete a 360-degree sequential shooting operation every fixed time interval. Several images are obtained in one shooting operation. Considering the ultra-wide viewing angle of the camera device, in this embodiment, the camera device obtains four images in one shooting operation: two images perpendicular to the road direction (shooting direction 180 degrees), and two images parallel to the road direction (shooting direction 180 degrees). At least one of these four images represents the actual placement of shared bicycles at the parking bay corresponding to the camera device.

[0053] Since the parking spaces next to the camera are fixed and the camera's installation position is also fixed, the camera only rotates horizontally during the shooting process and does not leave its installation position. Therefore, the actual image order in all images is fixed. Figure 2 This is a diagram showing the positional relationship between the camera device and the parking frame in a certain sub-region provided in this application. For example... Figure 2 As shown, a maximum of two parking frames will be placed next to the camera device. If two parking frames are placed, they will be located on either side of the camera device and parallel to the road. If only one parking frame is placed, it will be located on one side of the camera device and parallel to the road. Only one parking frame will be displayed in each actual image. The parking frame number corresponding to the parking frame next to the camera device is stored in the camera device. Thus, when the camera device sends the actual image to the bicycle management system, it also sends the corresponding parking frame number to the bicycle management system, enabling the bicycle management system to obtain image information about the bicycle placement at that parking frame.

[0054] In this embodiment, other camera devices also send the image information of the bicycle placement at the corresponding parking space to the bicycle management system according to the above steps. In this way, the image information of the bicycle placement at each parking space can be automatically obtained at fixed intervals, without the need for staff to manually input the image information of the bicycle placement at each parking space.

[0055] Step S200, whether the actual image corresponding to the management task needs to be generated according to each actual image in turn, if necessary, the management task is generated according to the actual image, and the image information and the management task are sent to the block chain, and the image information and the management task are chained through the content storage or hash storage method, so as to be stored in the block chain, wherein the management task has an associated relationship with the image information.

[0056] Figure 3 The block diagram provided by the present embodiment is used to judge whether the actual image corresponding to the management task needs to be generated according to each actual image in turn. As shown in Figure 3 The step of judging whether the actual image corresponding to the management task needs to be generated according to each actual image in turn includes the following steps:

[0057] Step S201, image processing is performed on the actual image in each image information to obtain a bicycle quantity corresponding to each actual image, which represents the number of bicycles placed, and a sorting quantity representing the number of bicycles to be sorted, wherein each bicycle quantity corresponds to a unique parking frame number, and each sorting quantity corresponds to a unique parking frame number.

[0058] Step S202, whether each bicycle quantity falls into the preset bicycle quantity range corresponding to the parking frame number is judged in turn, if not, the image information corresponding to the bicycle quantity needs to generate the management task.

[0059] Step S203, if it falls into, it is judged whether the management quantity corresponding to the parking frame number is zero, if it is zero, the image information corresponding to the bicycle quantity does not need to generate the management task.

[0060] Step S204, if it is not zero, the first parking frame number corresponding to the bicycle quantity is obtained, the second parking frame number belonging to the same sub-region as the first parking frame number is obtained, the to-be-completed quantity of the management task corresponding to all second parking frame numbers is determined according to the second parking frame number, whether the to-be-completed quantity is less than the regular task quantity is judged, if it is less than, the image information corresponding to the bicycle quantity needs to generate the management task.

[0061] Step S205, if it is not less than, the image information corresponding to the bicycle quantity does not need to generate the management task.

[0062] After receiving the image information, the single bicycle management system can preliminarily process the actual image in each image information by using OpenCV technology, that is, extract all information in the actual image to obtain the vehicle in the actual image, and then compare each vehicle with the shared bicycle of the designated operator in terms of features, so as to obtain the single bicycle quantity corresponding to each actual image, which represents the number of single bicycles. The single bicycle quantity refers to the number of single bicycles of a certain operator and the number of single bicycles placed in the set range of the parking frame area. The set range can be determined according to the actual situation, and generally the area formed by the parking frame area as the center and the distance from the parking frame area as a single bicycle length.

[0063] In addition, after completing the preliminary preprocessing operation and obtaining the single bicycle quantity corresponding to each actual image, each actual image is cropped according to the parking frame to obtain the corresponding sub-actual image, and then one of the LBP algorithm, the HOG feature extraction algorithm or the SIFT operator is used to obtain the actual feature information corresponding to each single bicycle in the sub-actual image. The actual feature information corresponding to each single bicycle is compared with the reference feature information in sequence. The reference feature information includes the first reference feature information representing the core components of the single bicycle and the second reference feature information representing the direction of the connection line between the front fork and the middle axis. The actual feature information corresponding to each single bicycle includes the first actual feature information representing the core components of the single bicycle and the second actual feature information representing the direction of the connection line between the front fork and the middle axis. If the first reference feature information corresponds to the first actual feature information and the second reference feature information corresponds to the second actual feature information, it indicates that the actual feature information corresponding to the single bicycle is consistent with the reference feature information, that is, the single bicycle is placed normally. If at least one of the first reference feature information does not correspond to the first actual feature information or the second reference feature information does not correspond to the second actual feature information, it indicates that the actual feature information corresponding to the single bicycle is inconsistent with the reference feature information, that is, the single bicycle is not placed normally, and the number of single bicycles not placed normally is the arrangement quantity representing the number of single bicycles that need to be arranged. The core components of the single bicycle include front wheel, rear wheel, seat, handlebar, pedal and chain.

[0064] The preset bicycle quantity range is a range of bicycle quantity allowed to be placed in the parking frame. The preset bicycle quantity range has a maximum value and a minimum value, and the minimum value is zero. The maximum value can be set according to the set length of the parking frame and the width of each shared bicycle. Each parking frame number corresponds to a preset bicycle quantity range. The core work of the staff is to complete the scheduling of shared bicycles, and the auxiliary work is to complete the arrangement of shared bicycles. Therefore, it is determined in sequence whether each bicycle quantity is greater than the maximum value of the preset bicycle quantity range corresponding to the parking frame number. If it is greater, it indicates that the bicycle quantity does not fall within the preset bicycle quantity range corresponding to the parking frame number, and there is the core work of scheduling the bicycles placed in the parking frame represented by the parking frame number corresponding to the bicycle quantity. Therefore, the image information corresponding to the bicycle quantity needs to generate a management task.

[0065] If it is not greater, it indicates that the bicycle quantity falls within the preset bicycle quantity range corresponding to the parking frame number, and there is no core work, and the bicycles placed in the parking frame represented by the parking frame number corresponding to the bicycle quantity do not need to be scheduled. However, considering the aesthetics of urban roads, when there is no core work, it is further determined whether there is the auxiliary work of arrangement, that is, under the premise that the bicycle quantity falls within the preset bicycle quantity range corresponding to the parking frame number, it is determined whether the management quantity corresponding to the parking frame number is zero. If it is zero, it indicates that there is neither the core work nor the auxiliary work, and the image information corresponding to the bicycle quantity does not need to generate a management task.

[0066] If it is not zero, the core work is primary and the auxiliary work is secondary. By obtaining the first parking frame number corresponding to the bicycle quantity, the second parking frame number belonging to the same sub-region as the first parking frame number, determining the to-be-completed quantity of management tasks corresponding to all second parking frame numbers according to the second parking frame number, the to-be-completed quantity represents the number of tasks that the staff needs to complete next, that is, the number of management tasks that the staff has not completed, which can be obtained by checking the terminal corresponding to the staff. Since the staff has limited energy, the number of tasks that can be completed in time is limited. The above-mentioned regular task quantity is the number of tasks that the staff can bear to complete within a specified time without work pressure. If the to-be-completed quantity is less than the regular task quantity, it indicates that the management task can be assigned to the staff, and the image information corresponding to the bicycle quantity needs to generate a management task. If the to-be-completed quantity is not less than the regular task quantity, since the arrangement work is not the core work, the image information corresponding to the bicycle quantity does not need to generate a management task. Among them, all parking frames in each sub-region correspond to different priorities. The management tasks corresponding to the parking frames with high priorities are processed first, and the management tasks corresponding to the parking frames with low priorities are processed second.

[0067] After obtaining the image information, the actual image in each image information is preliminarily processed to obtain the corresponding number of bicycles and the number of arrangements, and then according to the importance of the work, it is judged in priority whether the number of bicycles falls into the preset number of bicycles corresponding to the parking frame frame, if it falls into, it indicates that there is a scheduling work as the core work, and the subsequent does not need to judge whether there is an arrangement work as an auxiliary work, and the image information corresponding to the number of bicycles can be directly determined not to generate a management task, so as to reduce the judgment times and improve the speed. If it does not fall into, further according to the number of to-be-completed corresponding to the work staff, it is further determined whether the image information corresponding to the number of bicycles needs to generate a management task, so as to avoid blindly generating a management task to increase the pressure of the work staff.

[0068] Each management task at least includes one of the scheduling task and the arrangement task. Figure 4 is a block diagram provided by the embodiment for generating a management task according to an actual image. As shown in Figure 4 generating a management task according to an actual image includes the following steps:

[0069] Step S206, if the number of bicycles does not fall into the preset number of bicycles, the number of bicycles to be taken away from the current parking frame is generated based on the number of bicycles and the preset number of bicycles, and the corresponding scheduling task is generated according to the number of taking away.

[0070] Step S207, judging whether the number of taking away is greater than the arrangement number corresponding to the number of bicycles, if it is not greater than, the arrangement number corresponding to the number of bicycles is subtracted by the number of taking away to obtain the to-be-arranged number which still needs to be arranged, and the corresponding first arrangement task is generated according to the to-be-arranged number.

[0071] Step S208, if the number of bicycles falls into the preset number of bicycles, the corresponding second arrangement task is generated according to the arrangement number corresponding to the number of bicycles.

[0072] In the case that the image information needs to generate a management task has been determined according to the image information, by judging whether the number of bicycles corresponding to the image information falls into the preset number of bicycles, it can be obtained that the management task is generated due to the scheduling work or the arrangement work. When the number of bicycles corresponding to the image information does not fall into the preset number of bicycles, it indicates that the management task is generated due to the scheduling work, at this time, the number of taking away of bicycles at the parking frame corresponding to the parking frame number corresponding to the image information is obtained based on the number of bicycles and the preset number of bicycles, and the corresponding scheduling task is generated according to the number of taking away, which indicates that the number of taking away of bicycles from the parking frame.

[0073] If the scheduling task is generated, it means that the staff needs to arrive at the designated parking frame to complete the work. In the spirit of optimizing the city and reducing the time spent by the staff on the way, it is further compared whether the number of vehicles to be transported is greater than the corresponding number of vehicles to be arranged. If it is not greater than, it means that after the staff transports the number of vehicles to be transported, there are still vehicles to be arranged in the parking frame. At this time, the number of vehicles to be arranged is obtained by subtracting the number of vehicles to be transported from the corresponding number of vehicles to be arranged. According to the number of vehicles to be arranged, a corresponding first arrangement task is generated. The first arrangement task indicates that the number of vehicles to be arranged needs to be arranged from the parking frame. At this time, the management task includes the scheduling task and the first arrangement task.

[0074] If it is greater than, it means that after the staff transports the number of vehicles to be transported, there are no vehicles to be arranged in the parking frame. No corresponding arrangement task is generated at this time. At this time, the management task only includes the scheduling task.

[0075] When the number of vehicles corresponding to the image information falls within the preset number of vehicles, it means that the management task is generated due to the arrangement work. At this time, a corresponding second arrangement task is generated according to the number of vehicles corresponding to the arrangement number. The second arrangement task indicates that the number of vehicles needs to be arranged from the parking frame represented by the parking frame number corresponding to the number of vehicles. At this time, the management task only includes the second arrangement task.

[0076] Wherein, the step S206 of generating the number of vehicles to be transported from the current parking frame based on the number of vehicles and the preset number of vehicles includes the following steps:

[0077] Step S206-1, obtaining the number of vehicles corresponding to the scheduling parking frame number of the current parking frame, and the backup parking frame number whose distance from the scheduling parking frame number does not exceed the preset distance.

[0078] Step S206-2, obtaining the number of backup vehicles placed in each backup parking frame number corresponding to the parking frame, and judging whether all the number of backup vehicles falls within the preset number of vehicles corresponding to each backup parking frame number. If it does not fall within, the number of vehicles is subtracted by the minimum value of the preset number of vehicles to obtain the number of vehicles to be transported.

[0079] Step S206-3, if at least one falls within, obtaining the middle value of the preset number of vehicles corresponding to the current parking frame, and subtracting the middle value from the number of vehicles corresponding to the current parking frame to obtain the number of vehicles to be transported.

[0080] The preset distance can be set according to actual conditions, and there is a parking frame in the preset distance. The actual distance between the parking frame and the parking frame corresponding to the dispatch parking frame number is not greater than the preset distance. The parking frame number corresponding to the number of single vehicles corresponding to the management task is the dispatch parking frame number. The parking frame corresponding to the dispatch parking frame number is the parking frame that needs to be completed by the staff. The parking frame number corresponding to the dispatch parking frame number is the backup parking frame number. The staff prefer to dispatch the single vehicle in the parking frame corresponding to the dispatch parking frame number to the parking frame corresponding to the backup parking frame number. Through the positioning system carried by each single vehicle, the number of backup single vehicles placed in the parking frame corresponding to each backup parking frame number can be obtained. If all the number of backup single vehicles do not fall within the corresponding preset single vehicle number range, it indicates that the staff cannot dispatch the single vehicle in the parking frame corresponding to the dispatch parking frame number to the parking frame corresponding to the backup parking frame number. Moreover, there are many single vehicles near the parking frame corresponding to the dispatch parking frame number. In order to reduce the number of dispatches, the number of single vehicles minus the minimum value of the preset single vehicle number range, which is zero, that is, the number of single vehicles corresponding to the dispatch parking frame number is the number of vehicles to be transported at this time.

[0081] If all the number of backup single vehicles at least one falls within the corresponding preset single vehicle number range, it indicates that the staff can dispatch the single vehicle in the parking frame corresponding to the dispatch parking frame number to the parking frame corresponding to the backup parking frame number. The average value of the maximum value and the minimum value of the preset single vehicle number range corresponding to the dispatch parking frame number is obtained to obtain the intermediate value. The number of single vehicles corresponding to the dispatch parking frame number is reduced by the intermediate value to obtain the number of vehicles to be transported. For example, the maximum value of the preset single vehicle number range corresponding to the dispatch parking frame number is 20, and the minimum value is 0. Then the intermediate value is (20+0) / 2=10.

[0082] If the absolute value of the difference between the number of bicycles in the backup and the maximum value of the preset bicycle quantity range corresponding to the number of bicycles in the backup is greater than the number of bicycles to be transported, then the bicycles corresponding to the number of bicycles to be transported are placed in the parking frame corresponding to the preset bicycle quantity range. If the absolute value of the difference between the number of bicycles in the backup and the maximum value of the preset bicycle quantity range corresponding to the number of bicycles in the backup is not greater than the number of bicycles to be transported, then part of the bicycles corresponding to the number of bicycles to be transported are placed in the parking frame corresponding to the preset bicycle quantity range. The total storage capacity of the parking frame corresponding to the backup parking frame number in the corresponding preset bicycle quantity range is obtained. If the number of bicycles to be transported is not greater than the total storage capacity, then the bicycles corresponding to the number of bicycles to be transported are placed in the parking frame corresponding to the backup parking frame number, wherein the number of bicycles in each parking frame corresponding to the backup parking frame number does not exceed the preset bicycle quantity range. If the number of bicycles to be transported is greater than the total storage capacity, then the number of bicycles to be transported is reduced by the total storage capacity to obtain a number of bicycles to be transported, and the total storage capacity of bicycles is placed in the parking frame corresponding to the backup parking frame number, wherein the number of bicycles in each parking frame corresponding to the backup parking frame number does not exceed the preset bicycle quantity range, and the number of bicycles to be transported is placed in other parking frames, so that the number of bicycles placed in all parking frames in the sub-area does not exceed the preset bicycle quantity range.

[0083] After the management task is generated, the bicycle management system sends the management task and the image information corresponding to the management task to the blockchain, and stores the management task and the image information corresponding to the management task in the blockchain by content storage or hash storage, so that the bicycle management system and each worker can view all management tasks and image information corresponding to the management tasks, and the integrity, authenticity, security and transparency of the management tasks and image information corresponding to the management tasks can be ensured. On the other hand, only after the management task is generated, the image information corresponding to the management task can be retained for subsequent disputes. Therefore, if the image information needs to generate a management task, the image information and the management task are sent to the blockchain, and the image information and the management task are stored in the blockchain by content storage or hash storage. If the image information does not need to generate a management task, the image information is not sent to the blockchain for storage, which can reduce the workload of the blockchain. The management task and the image information have an association relationship.

[0084] In step S300, the management task is sent to the corresponding worker, the result information obtained by each worker according to the management task is obtained, the management task is ended according to the result information, and the result information is sent to the blockchain for storage.

[0085] Each worker obtains all management tasks sent by the bicycle management system to the blockchain through the blockchain, and receives the corresponding management task according to the parking frame number corresponding to the worker, so as to complete the management task. After each worker completes a management task, the worker takes a photo by using a related device to obtain result information including a result image and a parking frame number corresponding to the result image, and sends the result information to the blockchain, and makes the result information be chained by using a content notarization or a hash notarization method, so as to be stored in the blockchain. Due to the openness, decentralization and difficulty to tamper of the blockchain, the bicycle management system and each worker can view all the result information, and the integrity, authenticity, security and transparency of the result information storage can be ensured.

[0086] In addition, the bicycle management system can obtain the result information obtained by each worker according to the management task through the blockchain, and end the management task according to the result information. Figure 5 is a block diagram provided by the embodiment for ending the management task according to the result information. As shown in Figure 5 , ending the management task according to the result information includes the following steps:

[0087] Step S301, pre-processing the result image in each result information to obtain the placement pose of all bicycles in each result image, and sequentially judging whether each placement pose meets a preset reference pose. If yes, marking the result information as qualified result information, and generating a qualified end instruction according to the qualified result information to end the management task.

[0088] Step S302, if not, marking the result information as a defect result information, and generating a defect end instruction according to the defect result information to end the management task.

[0089] Each result image is cropped according to the parking frame to obtain a corresponding sub-result image, and then one of an LBP algorithm, a HOG feature extraction algorithm or a SIFT operator is used to obtain result feature information corresponding to each bicycle in the sub-result image. Each result feature information includes a plurality of sub-result feature points, and the front fork result feature point corresponding to the front fork and the middle shaft result feature point corresponding to the middle shaft are obtained from the plurality of sub-result feature points. The placement angle of the connecting line of the two feature points is obtained according to the front fork result feature point and the middle shaft result feature point. The above operation is performed on each result feature information to obtain the placement angle of all bicycles in each result image.

[0090] The preset reference angle is an angle at which a bicycle is placed in a parking frame. If the difference between the placement angle of all bicycles in a result image and the reference angle is within the allowable error range, it indicates that the placement angle of all bicycles in the result image meets the preset reference angle, i.e., all bicycles at the parking frame are normally parked in the parking frame, the staff completes the management task, the result information sent to the blockchain is qualified, the bicycle management system marks the result information as qualified result information through keyword technology, and generates a qualified end instruction according to the qualified result information, fills in the keyword in the management task according to the qualified end instruction, and ends the management task. Finally, the ended management task is sent to the blockchain for complete, true, safe and transparent recording.

[0091] Similarly, if the difference between the placement angle of at least one bicycle in a result image and the reference angle is not within the allowable error range, it indicates that the placement angle of not all bicycles in the result image meets the preset reference angle, i.e., not all bicycles at the parking frame are normally parked in the parking frame, the staff does not complete the management task, the result information sent to the blockchain has defects, the bicycle management system marks the result information as defective result information through keyword technology, and generates a defective end instruction according to the defective result information, fills in the keyword in the management task according to the defective end instruction, and ends the management task. Finally, the ended management task is sent to the blockchain for complete, true, safe and transparent recording.

[0092] After the staff completes the management task, the corresponding result information is sent to the blockchain, which can ensure that the result information is recorded completely, truly, safely and transparently, and also allows the bicycle management system to obtain the result information through the blockchain and determine whether the result information submitted by the staff is qualified by auditing the result information, thereby supervising the work of the staff.

[0093] Step S400, obtaining the management task and the corresponding result information from the blockchain for public display.

[0094] The step of obtaining the management task and the corresponding result information from the blockchain for public display includes the following steps:

[0095] Step S401, obtaining the current time and the historical time of the last public display, subtracting the historical time from the current time to obtain a time difference, determining whether the time difference falls within a preset time range, if it falls within, generating a reading instruction to obtain the management task and the corresponding result information stored within the time difference from the blockchain, and sending them to all terminal devices corresponding to the staff for public display.

[0096] Step S402, if not, continue to obtain the current time, and judge whether the time difference falls within the preset time range.

[0097] Even if the staff and bicycle management system can obtain the management task and the corresponding result information in real time through the blockchain, but due to the busy work of the staff, the staff can not check the management task and the corresponding result information in time. The management system sends the management task and the corresponding result information obtained in this period of time to all staff from the blockchain every fixed time interval, which not only ensures that all staff can receive the management task and the corresponding result information in time, but also reduces the workload of the staff in obtaining the management task and the corresponding result information through the blockchain.

[0098] In addition, the management task and the corresponding result information that have been publicized are marked after being sent to all staff for publicity. Among them, the management task corresponding to the result information marked in different batches is different, which facilitates marking only the management task and the corresponding result information without marking during the next publicity. In this way, even if the corresponding error operation of the management task and the result information occurs, the corresponding batch of management task and result information can be accurately found according to different marks, which is more convenient and faster than searching for information from all management tasks and result information.
