Description

Technical Field

[0001] The present invention relates to the field of logistics and transportation technology, and in particular to a traceable logistics monitoring method based on blockchain. Background Art

[0002] The logistics industry has developed into an indispensable part of people's lives. Whether it is express delivery or other logistics transportation, it has brought great convenience to people's lives. In the process of logistics transportation and management, it is necessary to plan and sort the route of each transported item to complete the transportation from the departure point to the destination. The existing logistics distribution process includes:

[0003] 1. Accept orders.

[0004] 2. Pick up: The courier will go to the pickup address specified by the customer according to the delivery range and time schedule. After arriving, the courier will verify the sender's identity and provide relevant information and supporting documents. Then, the courier will weigh the express and calculate the price, charge the customer, and place the package in the delivery vehicle.

[0005] 3. Transportation: The delivery personnel gather all the parcels at the delivery station (or express delivery center), and then classify, sort and load the parcels according to the waybill number. The vehicles transport the parcels on the specified routes to ensure the safety of the parcels and reach the destination as quickly as possible.

[0006] 4. Delivery: When the vehicle arrives at the distribution station in the target city or region, the parcels will be sorted again and assigned to specific couriers according to the destination. The couriers will deliver the parcels one by one to the address specified by the recipient according to the delivery list and map and a certain route.

[0007] 5. Sign for the package: When the courier delivers the package to the recipient, the recipient needs to confirm the completeness and accuracy of the package. The recipient will sign for the express delivery slip or sign for confirmation on the courier's mobile device. In special circumstances, the recipient can also authorize someone else to sign for the package.

[0008] However, in the existing logistics distribution, problems such as damaged express and replaced express still occur from time to time, and it is very troublesome to trace them when they are found. When it is necessary to check the problems of damaged and replaced express, it is necessary to call the monitoring of different distribution stations to continuously check the monitoring to find the time of damage or replacement. In addition, the problem of damaged express is very difficult to check because the resolution of the monitoring is insufficient and the damage is difficult to be found; that is to say, the precise control and precise traceability of logistics management need to be strengthened; if each express is taken a photo to detect whether it is damaged, the cost is huge. Therefore, it is necessary to provide a blockchain-based traceable logistics monitoring method that can avoid damaged express and replaced express and has controllable costs. Summary of the invention

[0009] The technical problem to be solved by the present invention is to provide a blockchain-based traceable logistics monitoring method that can avoid express delivery damage and replacement and has controllable costs.

[0010] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0011] A traceable logistics monitoring method based on blockchain, comprising:

[0012] Step 1: Order acceptance: The customer places an order on the platform and marks the pickup address and delivery address. The platform sends the pickup address to the delivery person;

[0013] Step 2: Pick up the package: The deliveryman goes to the pickup address specified by the customer, performs initial weighing to obtain the initial weight, and uses cartons to pack the customer's package under the customer's supervision to form an express package. The deliveryman uses a hammer to knock the package and uses the terminal to record the first knocking sound. At the same time, the weighing machine is used to weigh the package for the first time to generate the first weighing result. The first weighing result and the first knocking sound are encrypted and uploaded to the blockchain. The platform considers the collection of the package to be completed after charging the customer based on the pickup address, the receiving address and the initial weight, and generates a waybill number;

[0014] Step 3, transportation: the deliveryman gathers all the express parcels collected at the starting distribution station, and the starting distribution station classifies, sorts and loads the express parcels according to the waybill number; the starting distribution station weighs the express parcels for a second time during sorting and uses the same hammer to knock them to produce a second knocking sound, and encrypts the second weighing result and the second knocking sound and uploads them to the blockchain; if it needs to pass through several other transit distribution stations for re-classification, sorting and loading during delivery to the recipient address, weighing is carried out to produce the third weighing result to the Nth weighing result and the same hammer is used to knock to produce the third knocking sound to the Nth knocking sound, and the third weighing result to the Nth weighing result and the third knocking sound to the Nth knocking sound are encrypted and uploaded to the blockchain; after loading is completed, it is delivered to the terminal distribution station corresponding to the recipient address by a transport vehicle;

[0015] Step 4: Delivery: When the transport vehicle arrives at the final delivery station in the target area, the express is sorted again and assigned to specific couriers according to the destination; the express is weighed and tapped for the last time during sorting, and the weighing generates the final weighing result and the final tapping sound, which are encrypted and uploaded to the blockchain; the couriers deliver the express to the recipient address according to the recipient address;

[0016] Step 5. Sign for the package. If the signatory has no objection, the logistics distribution is completed. If the signatory believes that the package is damaged or has been replaced, the platform will perform the first judgment process: obtain the first weighing result, the second weighing result, ..., and the final weighing result uploaded on the blockchain and compare them in turn. If the difference between the previous weighing result and the next weighing result is greater than the first preset value, it is determined that there is a problem and the corresponding stage is output. At the same time, the platform will perform the second judgment process: obtain the first knocking sound, the second knocking sound, ..., and the final knocking sound uploaded on the blockchain and compare them in turn. If the difference between the tone of the previous knocking sound and the tone of the next knocking sound is greater than the second preset value, it is determined that there is a problem and the corresponding stage is output. Obtain the stages output by the first judgment process and the second judgment process. If the stages overlap, the video stored locally at the distribution station corresponding to the stage will be called first for search. If the stages do not overlap, the videos stored locally at the distribution station of all output stages will be searched.

[0017] Preferably, the striking hammer is a fascia gun, and the striking hammer uses the same gear when striking.

[0018] Preferably, the sound lengths of the first knocking sound, the second knocking sound, ..., and the final knocking sound are all 1-3 seconds.

[0019] Preferably, the first knock sound, the second knock sound, ..., and the final knock sound are all compressed and then encrypted before being uploaded to the blockchain.

[0020] Preferably, when loading, the platform calculates the total weight of the loading and the mass distribution during loading based on the second weighing results to the Nth weighing results.

[0021] Preferably, the platform executes the first judgment process and the second judgment process in advance when obtaining the second weighing result, ..., the final weighing result and the second knocking sound, ..., the final knocking sound, obtains the output stages of the first judgment process and the second judgment process, and calls the videos of all the output stages.

[0022] Preferably, when calling the videos of all stages of the output, the platform stores the videos locally on the platform at the same time.

[0023] Preferably, the video stored locally on the platform is deleted after the logistics delivery is completed.

[0024] Preferably, the platform counts the frequency of the delivery stations corresponding to the stage output, and if the number of times the delivery station appears is greater than a third preset value, a notification is made to the platform.

[0025] Preferably, when a knocking hammer is used to knock the express delivery, a certain side of the express delivery is set as the knocking surface, and the knocking hammer knocks the knocking surface.

[0026] The beneficial effects of the present invention are as follows: by utilizing blockchain technology, the weighing results and knocking sounds are encrypted and uploaded, thereby ensuring the immutability and security of data during transmission; since weighing is performed separately at the collection and distribution stations, by calculating whether the weight of the express parcels has changed, it is determined whether a problem has occurred; by comparing the difference in consecutive weighing results and the sound changes of the knocking sounds, it is possible to detect abnormal conditions in the logistics process and reduce errors; the principle is that with existing express parcel replacement, if the express parcel is to be opened again after packaging, the items in the express parcel will be replaced or the express parcel will be damaged, which will inevitably lead to a change in weight, so the first judgment process can make a judgment; further, in order to avoid the express parcel being stuffed with other things after being replaced, or the express parcel being damaged but only broken without any weight loss In the event of loss, the second judgment process is introduced simultaneously. Due to the structural changes caused by the damaged cartons, the tone of the cartons after being knocked before and after the damage will change. Furthermore, when the express is replaced, the internal packaging method, spatial position, and guaranteed thickness will change due to re-packaging, and the shape, thickness, position, etc. of the packaging cannot be 100% the same as the original. The superposition of these factors will cause changes in the internal space, and then the knocking tone generated when knocking will also change. Therefore, by adopting the changes in weight and sound, the detection of damaged and replaced express can be realized. By selecting the video of the corresponding stage, the stage where the express has problems can be quickly found. The stage is the process between each weighing result or the process between each knocking sound. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Explanation of the numbers: 1. Express; 2. Striking hammer; 3. Striking surface. DETAILED DESCRIPTION

[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0031] Please refer to Figure 1 as well as Figure 2 , a traceable logistics monitoring method based on blockchain, including:

[0032] Step 1: Order acceptance: The customer places an order on the platform and marks the pickup address and delivery address. The platform sends the pickup address to the delivery person;

[0033] Step 2: Pick up the package: The deliveryman goes to the pickup address specified by the customer, performs initial weighing to obtain the initial weight, and uses cartons to pack the customer's package under the customer's supervision to form Express 1. The deliveryman uses hammer 2 to knock on Express 1 and uses the terminal to record the first knocking sound. At the same time, the weighing machine is used to weigh Express 1 for the first time to generate the first weighing result. The first weighing result and the first knocking sound are encrypted and uploaded to the blockchain. The platform considers the collection of the package to be completed after charging the customer based on the pickup address, the receiving address and the initial weight, and generates a waybill number;

[0034] Step 3, transportation: the deliveryman gathers all the express parcels 1 collected at the starting distribution station, and the starting distribution station classifies, sorts and loads the express parcels 1 according to the waybill number; the starting distribution station weighs the express parcel 1 for a second time during sorting and uses the same knocking hammer 2 to knock to produce a second knocking sound, and encrypts the second weighing result and the second knocking sound and uploads them to the blockchain; if it needs to pass through several other transit distribution stations for re-classification, sorting and loading during delivery to the recipient address, weighing is performed to produce a third weighing result to the Nth weighing result and the same knocking hammer 2 is used to knock to produce a third knocking sound to the Nth knocking sound, and the third weighing result to the Nth weighing result and the third knocking sound to the Nth knocking sound are encrypted and uploaded to the blockchain; after loading is completed, it is delivered to the terminal distribution station corresponding to the recipient address by a transport vehicle;

[0035] Step 4: Delivery: When the transport vehicle arrives at the terminal distribution station in the target area, Express 1 is sorted again and assigned to a specific delivery person according to the destination; during sorting, Express 1 is weighed and tapped for the last time, and the weighing generates the final weighing result and the final tapping sound, which are encrypted and uploaded to the blockchain; the delivery person delivers Express 1 to the recipient address according to the recipient address;

[0036] Step 5. Sign for the package. If the signatory has no objection, the logistics distribution is completed. If the signatory believes that the package 1 is damaged or has been replaced, the platform performs the first judgment process: obtain the first weighing result, the second weighing result, ..., and the final weighing result uploaded on the blockchain and compare them in turn. If the difference between the previous weighing result and the next weighing result is greater than the first preset value, it is determined that there is a problem and the corresponding stage is output. At the same time, the platform performs the second judgment process: obtain the first knocking sound, the second knocking sound, ..., and the final knocking sound uploaded on the blockchain and compare them in turn. If the difference between the tone of the previous knocking sound and the tone of the next knocking sound is greater than the second preset value, it is determined that there is a problem and the corresponding stage is output. Obtain the stages output by the first judgment process and the second judgment process. If the stages overlap, the video stored locally at the distribution station corresponding to the stage is preferentially called for search. If the stages do not overlap, the videos stored locally at the distribution station of all output stages are searched.

[0037] From the above description, it can be seen that by utilizing blockchain technology, the weighing results and knocking sounds are encrypted and uploaded, ensuring the immutability and security of the data during transmission. Since the weighing is performed separately at the pickup and delivery stations, by calculating whether the weight of the express 1 has changed before and after, it is determined whether a problem has occurred. By comparing the difference in continuous weighing results and the sound changes of the knocking sounds before and after, it is possible to detect abnormal situations in the logistics process and reduce errors. The principle is: if the existing express 1 is replaced and the express 1 is to be opened again after packaging, the express 1 will be replaced with items or damaged, which will inevitably lead to a change in weight. Therefore, the first judgment process can make a judgment. Furthermore, in order to avoid the express 1 In the case where other things are stuffed into Parcel 1 after being replaced, or Parcel 1 is only damaged but there is no weight loss, the second judgment process is introduced simultaneously. Since the damaged carton causes structural changes, the tone of the carton after being knocked before and after the damage will change. Furthermore, when Parcel 1 is replaced, the internal packaging method, spatial position, and guaranteed thickness will change due to re-packaging, and the shape, thickness, position, etc. of the packaging cannot be 100% the same as the original. The superposition of these factors will cause changes in the internal space, and then the knocking tone generated when knocking will also change. Therefore, by adopting changes in weight and sound, the detection of damage and replacement of Parcel 1 can be achieved.

[0038] Furthermore, the percussion hammer is a fascia gun, and the percussion hammer uses the same gear when striking.

[0039] From the above description, it can be seen that by using a fascia gun as a striking hammer, since the fascia gun can be produced as a standardized product and the gear strength is adjustable, the strength of each strike is guaranteed to be the same, so that the first knocking sound, the second knocking sound,..., and the final knocking sound have small interference factors, which is convenient and easy to compare, and avoids deviations in the knocking strength of the distribution station staff, resulting in excessive deviations.

[0040] Furthermore, the sound lengths of the first knocking sound, the second knocking sound, ..., and the final knocking sound are 1-3 seconds.

[0041] From the above description, it can be seen that by setting the sound length to 1-3 seconds, it is possible to ensure that the sound length is sufficient without increasing too much occupied space, thereby achieving cost control, especially compared to photos.

[0042] Furthermore, the first knock, the second knock, ..., and the final knock are compressed and then encrypted before being uploaded to the blockchain.

[0043] From the above description, it can be seen that the compressed sound can achieve lower occupied space, thereby reducing the chain cost.

[0044] Furthermore, when loading, the platform calculates the total weight of the loading and the mass distribution during loading based on the second weighing results to the Nth weighing results.

[0045] From the above description, it can be seen that by utilizing weighing, the stability of the vehicle during transportation is ensured to avoid overloading or unstable center of gravity.

[0046] Furthermore, the platform executes the first judgment process and the second judgment process in advance when obtaining the second weighing result, ..., the final weighing result and the second knocking sound, ..., the final knocking sound, obtains the output stages of the first judgment process and the second judgment process, and calls the videos of all the output stages.

[0047] It can be seen from the above description that by executing the first judgment process and the second judgment process in advance, problems can be discovered in time to prevent others from deleting or modifying the video.

[0048] Furthermore, when calling the videos of all stages of the output, the platform stores the videos locally on the platform at the same time.

[0049] From the above description, it can be seen that by storing the video locally on the platform at the same time when calling the video of all stages of the output, the call failure can be avoided.

[0050] Furthermore, the videos stored locally on the platform are deleted after the logistics delivery completes the delivery.

[0051] Furthermore, the platform counts the frequency of the delivery station corresponding to the stage output, and if the number of times the delivery station appears is greater than a third preset value, a notification is made to the platform.

[0052] From the above description, it can be seen that by introducing an evaluation mechanism for problems, the platform can count the distribution stations that often have problems, facilitate intervention management, and eliminate the problems at the source.

[0053] Furthermore, when the hammer 2 is used to strike the express 1 , a certain side surface of the express 1 is set as the striking surface 3 , and the hammer 2 strikes the striking surface 3 .

[0054] From the above description, it can be seen that the tone of the knocking sound produced by knocking will also change, especially the sides. If it is the top or bottom surface, it will be affected by the objects rising up or sinking to the bottom when packaged, while the sides are prone to have space and thus produce a hollow drum effect, which is also the place most prone to changes.
