Optionally, the sensor sub-module 201 may include a light sensor. When the amount of light entering the smart express box is less than the threshold, the circuit of the light sensor works at low level "0"; when the amount of light entering the smart express box is greater than or equal to the threshold, The circuit of the light sensor works at high level "1". Since the amount of light entering the smart express box changes when it is opened or damaged, it can be determined based on the level state of the light sensor circuit whether the smart express box is opened or damaged. The positioning sub-module 202 may include a global positioning system (GPS), or may be a Beidou system or a Galileo system.

It should be noted that in the embodiment of the present invention, the sensor sub-module of the smart express box is always in the working state during transportation, and the positioning sub-module only starts to work when the amount of light detected by the sensor sub-module is greater than or equal to the threshold, and the smart express box is recorded. The location of the express box. When the smart express box enters the transfer station, it can receive the status update request message sent by the logistics terminal. At this time, the smart express box executes a self-test program to detect whether each module is working normally; when each module of the smart express box is working normally, the positioning sub-module It can start working and send the light intensity information collected by the sensor sub-module during transportation and the position information recorded by the positioning sub-module during transportation, as well as the position information recorded by the positioning sub-module at the current moment, to the logistics terminal through the communication module. Both the data information sent and received by the smart express box need to be processed by the environment module. For example, when the smart express box is signed for, the environment module verifies the signature request message; for example, when the status information is updated, the environment module verifies the status information obtained by the detection module. After processing, it is sent by the communication module.

According to the above-mentioned logistics monitoring system, as shown in Figure 6, an embodiment of the present invention provides a logistics monitoring method, including:

S301. The logistics monitoring device obtains the status information of the smart express box.

Among them, the status information includes the first amount of light entering the smart express box.

Specifically, after the packaging of the smart express box is completed, the first amount of light entering the box remains unchanged, that is, the light sensor always works in the low-level state "0". When the smart express box is opened or damaged, the first amount of light entering the box increases, and the light sensor works in the high-level state "1". Therefore, the embodiment of the present invention determines whether the smart express box has been opened or damaged by monitoring changes in the first amount of light entering the smart express box in real time. The first amount of light entering the smart express box can be monitored in real time by the logistics monitoring device. The logistics monitoring device here can be an independent functional module or multiple functional modules integrated on the smart express box, as shown in Figure 4 above. The detection module, communication module, power module, etc. shown below.

It should be noted that after the detection module of the logistics monitoring device determines the first amount of light entering the smart express box, the environment module needs to determine the level signal corresponding to the first amount of light entering. A high level "1" corresponds to the first amount of light entering being greater than or Equal to the first threshold, the low level "0" corresponds to the first amount of incident light being less than the first threshold. The environment module actually uses the level signal to determine whether the smart express box has been opened or damaged, but its essence is to detect the first amount of light entering the smart express box. Therefore, in this embodiment, the amount of light entering will be used to determine whether the smart express box has been opened or damaged. Open or broken.

S302. If the logistics monitoring device determines that the first amount of incident light is greater than or equal to the first threshold, determine the first time and the position of the smart express box at the first time.

The first time is the time when the first amount of light entering the smart express box is greater than or equal to the first threshold.

Specifically, the first threshold here can be obtained through experiments by those skilled in the art, or the amount of light entering when the smart express box is in a sealed state can be set as the first threshold, which is not limited by the embodiment of the present invention.

During the transportation of the smart express box, if the logistics monitoring device detects that the first amount of light entering the smart express box is greater than or equal to the first threshold, it can be determined that the smart express box is opened or damaged. At this time, the logistics monitoring device can locate the position of the smart express box and the first time when the first amount of light is greater than or equal to the first threshold. As a result, the logistics monitoring device can determine the time and location when the smart express box is opened or damaged, thereby enabling traceability of responsibility.

It should be noted that after the smart express box is opened or damaged during transportation, the logistics service provider may repackage the smart express box. At this time, the first amount of light entering the smart express box can be less than the first threshold. When the first amount of light entering the smart express box is less than the first threshold, the logistics monitoring device can record the fourth time and the position of the smart express box at the first time again. Thus, the logistics monitoring device can determine that the smart express box was opened or damaged before the first time and the fourth time, and the road section where the smart express box was opened or damaged. The fourth time here is the time when the first amount of light entering the smart express box is less than the first threshold.

When the logistics monitoring device determines the position of the smart express box at the first time and the fourth time, its positioning sub-module can only work at the first time and the fourth time, or it can be in both the first time and the fourth time period. The working state is not limited by the embodiment of the present invention. In order to save energy, in the embodiment of the present invention, it is preferred that the positioning sub-module only works at the first time and the fourth time.

S303. The logistics terminal sends a status update request message to the logistics monitoring device.

Among them, the status update request message is used to request the status information of the smart express box. The status information also includes the corresponding time when the first amount of incident light changes and the position of the smart express box.

Specifically, when the smart express box arrives at the transfer station, the logistics terminal sends an update request message to the logistics monitoring device, requesting the status information of the smart express box from the previous transfer station to the current transfer station.

S304. The logistics monitoring device receives the status update request message.

S305. The logistics monitoring device sends status update information to the logistics terminal.

Among them, the status update information includes the first amount of light entering the smart express box, as well as the corresponding time and the position of the smart express box when the first amount of light entering changes.

Specifically, after receiving the status update request message sent by the logistics terminal, the logistics monitoring device needs to perform a self-check on the smart express box to determine whether the smart express box is working properly. If the smart express box works normally, the logistics monitoring device sends status update information to the flow terminal; if the smart express box fails to work normally, the logistics service provider needs to check the smart express box to determine whether there is a problem with the transported items; if there is a problem with the transported items If there is a problem, the logistics service personnel responsible for transportation will be held accountable in a timely manner; if there are no problems with the transported items, the logistics service provider will reset the smart express box to make it work normally.

S306. The logistics terminal receives the status update information and stores the status update information in the blockchain server.

Specifically, the status update information may also include the time when the smart express box left the previous transfer station and the time when it arrived at the current transfer station. The logistics terminal receives the status update information and determines whether the first amount of light entering the smart express box changes between the time it leaves the previous transfer station and the time it arrives at the current transfer station; if within this period of time, the first amount of light entering the smart express box changes If the amount of light is less than the first threshold, it is determined that the smart express box has not been opened or damaged; if within this period of time, there is a period when the first amount of light entering the smart express box is greater than or equal to the first threshold, then it is determined that the smart express box has been opened or damaged. damaged. At this time, if there is a problem with the items transported by the smart express box, it can be determined that the responsibility lies with the logistics service provider responsible for transportation during that period of time.

After the logistics terminal receives the status update information, it can be stored in the blockchain server to facilitate users or merchants to query the corresponding status.

It should be noted that the logistics monitoring device can send status update information to the logistics terminal through NFC or through the mobile cellular network. If the logistics monitoring device sends status update information through NFC, the status update information can be sent to the logistics terminal when the smart express box enters the transfer station, that is, step S303 is executed after step S302; if the logistics monitoring device sends status update information through the mobile cellular network , then when it is detected that the first light input amount of the smart express box is greater than or equal to the first threshold, the status update information can be sent to the logistics terminal, that is, step S305 is executed after step S302. Of course, if the logistics monitoring device sends status update information through the mobile cellular network, it can also send the status update information to the user terminal and merchant terminal, so that the user terminal and merchant terminal can understand the transportation status of the smart express box in a timely manner.

Optionally, when the smart express box leaves the current transfer station, the logistics terminal needs to send a status update request message to the logistics monitoring device again, so that the logistics monitoring device and the logistics terminal perform the above steps S304-S306 again to ensure that the smart express box is in transit. It has not been opened or damaged during the station transfer period.

The embodiment of the present invention determines whether the smart express box is opened or damaged by real-time monitoring of changes in the amount of light entering the smart express box; when the amount of light entering the smart express box is greater than or equal to the first threshold, it can be determined that the smart express box is opened or damaged. At this time, the time and location when the smart express box was opened or damaged can be determined, and the person responsible for the logistics loss can be traced through the time and location of the smart express box being opened or damaged.

Optionally, as shown in Figure 7, before step S301, it also includes initializing the smart express box, specifically including:

S401. The logistics terminal sends an initialization instruction to the logistics monitoring device.

Among them, the initialization command is used to instruct the logistics monitoring device to perform self-test on the smart express box to confirm that each module of the smart express box is working properly.

Specifically, after the items that need to be delivered are put into the smart express box and packaged, the logistics terminal sends an initialization instruction to the logistics monitoring device, instructing the logistics monitoring device to detect each module of the smart express box to ensure that the smart express box is being transported normal operation of the process.

S402. The logistics monitoring device receives the initialization instruction and detects whether the smart express box is working normally according to the initialization instruction.

Specifically, after the logistics monitoring device receives the initialization command, the environment module starts the detection program and detects the communication module, detection module, power module and other modules respectively to determine whether they are working normally.

If the logistics monitoring device determines that the communication module, detection module, power module and other modules are all working normally, it is determined that the smart express box is working normally; if the logistics monitoring device determines that any module among the communication module, detection module and power module is working abnormally, then It is determined that the smart express box is working abnormally. At this time, the smart express box needs to be reset until the smart express box works normally.

S403. If the logistics monitoring device determines that the smart express box is working normally, determine the second light input amount of the smart express box.

Specifically, when the logistics monitoring device determines that the smart express box is working normally, it is necessary to determine the second light input amount of the smart express box to ensure that the smart express box is packaged and sealed intact.

S404. If the logistics monitoring device determines that the second incident light amount is greater than or equal to the first threshold, it sends an error message to the logistics terminal.

Among them, the error message is used to indicate that the smart express box packaging does not meet the requirements.

Specifically, if the logistics monitoring device detects that the second light input amount of the smart express box is greater than or equal to the first threshold, it can be determined that the smart express box is not sealed well and needs to be repackaged. At this time, the logistics monitoring device can send error information to the logistics terminal.

S405. If the logistics monitoring device determines that the second amount of incident light is less than the first threshold, determine the second time and the position of the smart express box at the second time, and send initial information to the logistics terminal.

The initial information includes the second time and the position of the smart express box at the second time, and the second time is the time when the logistics monitoring device obtains the second amount of light.

Specifically, when the logistics monitoring device detects that the second light input amount of the smart express box is less than the first threshold, it can be determined that the smart express box has been packed well. At this time, the logistics monitoring device can send initial information to the logistics terminal to record the smart express box. The time and location of the issue.

S406. The logistics terminal receives the initial information and stores the initial information in the blockchain server.

Specifically, after receiving the initial information, the logistics terminal can store the initial information in the blockchain server to facilitate query by users and merchants. At the same time, logistics service providers can send out smart express boxes.

In this embodiment, through the initialization operation of the smart express box, it can be ensured that the items are packaged intact and no problems occur when they are sent out. When there is a problem with the transported items, the responsibility of the logistics starting point and the merchant can be excluded.

Optionally, as shown in Figure 8, before step S401, it also includes:

S501. The user terminal sends product information to the merchant terminal.

Among them, the product information is the attribute information of the items in the smart express box, which can be the name, quantity, color, material, etc. of the item.

Specifically, before mailing the item, the user terminal needs to check the attribute information of the mailed item with the merchant terminal, that is, the user terminal generates product information and sends the product information to the merchant terminal.

Before the user terminal sends product information to the merchant terminal, it also needs to generate a public key to encrypt the sent data information. The user terminal is deployed with a trusted execution environment for encrypting data information. The process of generating a public key by the user terminal can be executed by the trusted execution environment of the user terminal, and the public key generated by the user terminal includes a first subkey, a second subkey and a third subkey. The first subkey, The public key can be obtained by splicing the second subkey and the third subkey. When the user terminal sends product information to the merchant terminal, it also needs to send the first subkey to the merchant terminal.

It should be noted that when the user terminal sends the product information and the first subkey to the merchant terminal, it can calculate the first hash value corresponding to the product information according to the hash algorithm, and store the first hash value in the blockchain server. The key generated by the user terminal can be stored in a trusted container provided by the trusted execution environment. The trusted container here is the above-mentioned TA.

S502. The merchant terminal receives the product information and confirms the product information.

Specifically, the merchant terminal is deployed with a trusted execution environment for encrypting data information. After receiving the product information and the first subkey, the merchant terminal stores the first subkey in the trusted container provided by the trusted execution environment, and calculates the second hash value corresponding to the product information according to the hash algorithm. The hash value can be stored in another trusted container.

The merchant terminal compares the second hash value with the first hash value stored in the blockchain server. If the first hash value and the second hash value are the same, a logistics application is initiated to the logistics terminal and the logistics service provider is requested to provide logistics services; if the first hash value and the second hash value are different, a new request is made to the user terminal. Product information.

S503. The merchant terminal sends a logistics application message to the logistics terminal.

Among them, the logistics application message is used to request the logistics service provider to provide logistics services.

S504. The logistics terminal receives the logistics application message and sends a confirmation request message to the user terminal.

The confirmation request message is used to request logistics information from the user terminal.

Specifically, after receiving the logistics application message, the logistics terminal can request logistics information from the user terminal, so that the user terminal provides accurate logistics information.

S505. The user terminal receives the confirmation request message and sends logistics information to the logistics terminal.

Specifically, after receiving the confirmation request message, the user terminal may send the second subkey and logistics information to the logistics terminal.

It should be noted that the user terminal can calculate the third hash value corresponding to the logistics information according to the hash algorithm, and store the third hash value in the blockchain server.

S506. The logistics terminal receives the logistics information and confirms the logistics information.

Specifically, the same as step S502, after receiving the logistics information, the logistics terminal can calculate the fourth hash value corresponding to the logistics information according to the hash algorithm, and compare the fourth hash value with the third hash value stored in the blockchain server. Compare the Greek values. If the fourth hash value is the same as the third hash value, it is determined that the logistics information is correct and the logistics service provider can provide logistics services; if the fourth hash value is different from the third hash value, the logistics information is re-requested from the user terminal .

It should be noted that in this step, the second subkey of the logistics terminal can be stored in a trusted container provided by the trusted execution environment, and the fourth hash value can be stored in another trusted container.

In this embodiment, the merchant terminal compares the product information provided by the user terminal, and the logistics terminal compares the logistics information provided by the user terminal, ensuring the accuracy of logistics items and avoiding errors in mailing items and errors in logistics information. of delivery errors.

Optionally, after the logistics terminal confirms the logistics information, the logistics information can also be sent to the logistics monitoring device. The logistics monitoring device will calculate a hash value again according to the hash algorithm and send the hash value to the logistics terminal. The logistics terminal compares the hash value with the third hash value in the blockchain server again to confirm the logistics information again.

Optionally, because the smart express box provided by the embodiment of the present invention is used to transport valuable items, before packaging the transported items, the merchant terminal can take photos of the items, encrypt the photos and store them in the blockchain server. The merchant terminal can send the public key used to decrypt the photos to the user terminal and logistics terminal, so that the user terminal and logistics terminal can query the photos of items stored in the blockchain server through the public key to confirm the mailed items.

Optionally, as shown in Figure 9, the logistics monitoring method also includes the signing process for smart express boxes, specifically including:

S601. The user terminal sends a signature request message to the logistics monitoring device.

The sign-in request message includes the current location of the user terminal.

Specifically, when the logistics service provider delivers the smart express box, the user terminal needs to sign for the smart express box. When signing for receipt, the user terminal sends a signature request message to the logistics monitoring device to confirm the accuracy of the signature information and avoid smart express box delivery errors.

S602. The logistics monitoring device receives the signature request message sent by the user terminal.

Specifically, after receiving the signature request message sent by the user terminal, the logistics monitoring device performs a self-check on the smart express box to confirm that the smart express box is working properly.

S603. If the distance between the recipient address and the current location of the user terminal is less than or equal to the second threshold, determine the change of the first incident light amount between the second time and the third time.

Among them, the third time is the current signing time of the smart express box.

Specifically, in the embodiment of the present invention, smart express boxes are usually used to transport valuables, so the delivery of smart express boxes can be set to a fixed location to avoid delivery errors. Of course, because the logistics information also includes the recipient's name, recipient's phone number, recipient's ID number, etc., the signature request message can also include the recipient's name, recipient's phone number, recipient's ID number, etc. When signing for the smart express box, it can also match information such as the recipient's name, recipient's phone number, and recipient's ID number. When these information are matched one by one, the smart express box is allowed to be signed for. At this time, the change of the first light input amount of the smart express box between the second time and the third time can be determined to determine whether the smart express box is opened or damaged.

S604. If the first amount of incident light is always less than the first threshold between the second time and the third time, send the signature completion information to the user terminal.

Among them, the signature completion information is used to indicate that the smart express box has been signed for.

S605. If the first amount of incident light is greater than or equal to the first threshold in the first time period between the second time and the third time, send alarm information to the user terminal.

Among them, the alarm information is used to indicate that the smart express box was opened or damaged in the first period of time.

Specifically, whether the smart express box was opened or damaged during transportation can be judged based on the change in the first light input amount between the second time and the third time. The method of judgment will not be described again. When it is determined that the smart express box has not been opened or damaged, the logistics monitoring device sends a signature completion message to the user terminal; otherwise, an alarm message is sent to the user terminal.

S606. The user terminal receives the signature completion information or alarm information, and stores the signature completion information or alarm information in the blockchain server.

Specifically, if the user terminal receives the signature completion information, the logistics of the smart express box is completed, and the signature completion information is stored in the blockchain server; if the user terminal receives the alarm information, it can refuse to sign the smart express box and store the alarm information to the blockchain server.

When the user terminal refuses to sign the smart express box, the blockchain server can be used to query the changes in the amount of light entering the smart express box during transportation, thereby determining the time and location when the smart express box was opened or damaged, and tracing the relevant responsible person.

It should be noted that in the embodiment of the present invention, when the logistics terminal, merchant terminal and user terminal store data in the blockchain server, they all need to sign the corresponding data in order to confirm the person in charge of the relevant node.

In the sign-in process of this embodiment, by confirming the changes in the amount of light entering the smart express box during transportation, it is possible to avoid problems caused by the logistics service provider in transporting items during the delivery process, and avoid the situation where problems with items are discovered after signing and the responsibilities cannot be assigned.

Optionally, in the above embodiment, the logistics terminal, merchant terminal and user terminal need to use the public key generated by the user terminal when storing data information in the blockchain server. Because a complete public key is stored in the user terminal, the user terminal can use its own stored public key to store data information to the blockchain server. When logistics terminals and merchant terminals store data information in the blockchain server, they need to obtain the complete public key generated by the user terminal.

For example, for the logistics terminal, taking the storage of status update information to the blockchain server as an example, the logistics terminal calculates the fifth hash value corresponding to the second sub-key according to the hash algorithm, and sends the fifth hash value to The user terminal compares the fifth hash value with the sixth hash value. The sixth hash value here is the hash value calculated by the user terminal based on the second subkey stored by itself. The comparison of the fifth hash value and the sixth hash value here is to verify the legitimacy of the logistics terminal. .

If the two are the same, the user terminal sends the first subkey and the third subkey to the logistics terminal; if the two are different, the user terminal can refuse to send the key information to the logistics terminal. After receiving the first sub-key and the third sub-key, the logistics terminal can splice its own second sub-key with the first sub-key and the third sub-key to obtain a complete public key, and use the complete The public key stores status updates to the blockchain server. After the storage of the status update information is completed, the logistics terminal can delete the first sub-key and the third sub-key.

Similarly, the merchant terminal also needs to verify its legitimacy, that is, the merchant terminal calculates the seventh hash value corresponding to the first subkey stored by itself according to the hash algorithm, and sends the seventh hash value to the user terminal, and the user The terminal compares the seventh hash value with the eighth hash value. The eighth hash value here is the hash value calculated by the user terminal based on the first subkey stored by itself. If the seventh hash value and the eighth hash value are the same, the user terminal sends the second subkey and the third subkey to the merchant terminal; if they are different, the user terminal can refuse to send the key information to the merchant terminal. . After receiving the second sub-key and the third sub-key, the merchant terminal can splice its own first sub-key with the second sub-key and the third sub-key to obtain a complete public key, and use the complete The public key stores the data to the blockchain server. After the data storage is completed, the logistics terminal can delete the first sub-key and the third sub-key.

It should be noted that in this embodiment, the public key generated by the user terminal is divided into three parts, and the user terminal stores one of them, which can avoid the interaction of their respective sub-keys between the merchant terminal and the logistics terminal, thereby contributing to the blockchain The server uploaded incorrect data information.

When the initialization module 704 determines that the smart express box is working normally, it determines the second light input amount of the smart express box.

If the detection module 701 determines that the second amount of incident light is greater than or equal to the first threshold, an error message is sent to the logistics terminal; the error message is used to indicate that the smart express box packaging does not meet the requirements.

If the detection module 701 determines that the second amount of incident light is less than the first threshold, it determines the second time and the position of the smart express box at the second time, and sends initial information to the logistics terminal; the initial information includes the second time and the position of the smart express box at the second time.
