[0013] Optionally, the data transmission strategy specifically includes: When the electronic seal is opened, the IoT transceiver module sends the real-time collected cargo status data at the first frequency.

[0014] When the electronic seal is not opened, the Internet of Things transceiver module switches to a second frequency to store cargo status data; the second frequency is lower than the first frequency.

[0015] Optionally, the cargo status data includes the cargo environment temperature, ambient humidity, air pressure, cargo location information, cargo vibration status, and cargo image information.

[0016] In a second aspect, the present application provides a system for collecting and monitoring data on the status of goods in transit, comprising: The password verification module is used to perform a dynamic password verification operation by the password control module of the electronic seal; the dynamic password verification operation is to compare and verify the dynamic password generated by the cloud with the password input by the user.

By comparing the dynamic password generated in the cloud with the password entered by the user, illegal opening can be effectively prevented to ensure the security of the data before collection. Secondly, when the electronic seal is opened, the wake-up instruction of the Internet of Things transceiver module is triggered to start the data transmission of the cargo status.

Finally, the received cargo status data is uploaded to the cloud server through the vehicle terminal. The cloud server can store, analyze and process the data to achieve remote monitoring and management of cargo status. This step allows relevant personnel to obtain cargo status information anytime and anywhere, improving the efficiency and accuracy of supervision. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Embodiment 1 like Figure 1 As shown, this embodiment provides a method for collecting and monitoring the status data of goods in transit, including: Step 101: The password control module of the electronic seal performs a dynamic password verification operation; the dynamic password verification operation is to compare and verify the dynamic password generated by the cloud with the password input by the user.

[0034] Step 102: When the electronic seal is opened, a wake-up command of the IoT transceiver module is triggered to start the data transmission of the cargo status.

[0035] Step 103: Establish a multi-level data transmission channel between the vehicle terminal and the Internet of Things transceiver module, and dynamically adjust the data transmission strategy of the Internet of Things transceiver module according to the status of the electronic seal; the data transmission strategy is to transmit the collected data in real time when the electronic seal is in the open state, and to perform local caching when the electronic seal is in the locked state until the next time the electronic seal is opened.

[0036] Step 104: Upload the received cargo status data to the cloud server via the vehicle-mounted terminal.

[0037] Wherein, when executing step 101, the dynamic password verification operation includes: When the number of consecutive incorrect password entries by the user reaches a predetermined threshold, the locking mechanism is triggered.

[0038] When the user enters the password outside the specified time, the locking mechanism is triggered.

[0039] Specifically, the electronic seal can communicate with the vehicle terminal. The user applies for unlocking through the APP, and a dynamic password is generated in the cloud and sent to the vehicle terminal. After the vehicle terminal receives the password, the password will be transmitted to the electronic seal, and the authorized person will be informed at the same time to open the electronic seal. The electronic seal control module compares the input password with the password transmitted by the vehicle terminal and verifies it. If the verification passes, it will be opened, otherwise it will remain locked. If the input error reaches a certain number of times to trigger the lock, there will be a log for the opening and closing of the electronic seal (including GPS location + NTP timestamp). Therefore, the electronic seal can ensure that only authorized personnel can open the electronic seal within the specified time to ensure the security of the cargo information.

[0040] In some embodiments, when executing step 102, the triggering condition of the wake-up instruction of the Internet of Things transceiver module includes: Receive notifications of electronic seal status changes sent by the vehicle-mounted terminal.

[0041] It is detected that the sudden change value of the internal environmental parameters of the vehicle cabin exceeds the preset threshold.

[0042] Specifically, once the electronic seal is opened, its status information will be transmitted to the vehicle terminal, which then notifies the IoT transceiver module. The IoT transceiver module then starts to send the collected cargo status data at a specific frequency until the data is received by the vehicle terminal and forwarded to the cloud server. The IoT transceiver module dynamically collects the cargo status, providing basic data for subsequent data transmission and analysis.

[0043] Wherein, when executing step 103, the data transmission strategy specifically includes: When the electronic seal is opened, the IoT transceiver module sends the real-time collected cargo status data at the first frequency.

[0044] When the electronic seal is not opened, the Internet of Things transceiver module switches to a second frequency to store cargo status data; the second frequency is lower than the first frequency.

[0045] Specifically, the IoT transceiver module in the carriage receives the data from the sensor and stores it in a short time. If it is detected that the electronic seal is in the open state, the IoT transceiver module will send the collected data to the vehicle terminal; if the electronic seal is locked and the carriage is closed, the IoT transceiver module will temporarily store the data and send it to the vehicle terminal after the electronic seal is opened. The vehicle terminal will upload the received cargo status data to the cloud server.

[0046] Among them, the cargo status data includes the ambient temperature, ambient humidity, air pressure, cargo location information, cargo vibration status and cargo image information.

[0047] After receiving the cargo status information, the cloud server can use advanced data analysis algorithms to conduct in-depth mining and analysis of the cargo status data to determine whether the cargo status is normal. For example, by analyzing the trend of temperature data, it can predict whether the cargo may be damaged by heat. If an abnormality is detected, an early warning message is generated in a timely manner and relevant personnel are notified.

[0048] By processing data, the cloud server can promptly detect abnormal situations in the transportation of goods and provide early warning information to relevant personnel so that timely measures can be taken to avoid loss of goods.

[0049] Embodiment 2 This embodiment provides a system for collecting and monitoring data on the status of goods in transit, including: The password verification module is used to perform a dynamic password verification operation by the password control module of the electronic seal; the dynamic password verification operation is to compare and verify the dynamic password generated by the cloud with the password input by the user.

[0050] The data transmission module is used to trigger the wake-up command of the Internet of Things transceiver module when the electronic seal is opened, and start the data transmission of the cargo status.

[0051] The transmission strategy module is used to establish a multi-level data transmission channel between the vehicle terminal and the Internet of Things transceiver module, and dynamically adjust the data transmission strategy of the Internet of Things transceiver module according to the status of the electronic seal; the data transmission strategy is to transmit the collected data in real time when the electronic seal is in the open state, and to execute local caching when the electronic seal is in the locked state until the next time the electronic seal is opened.

[0052] The data upload module is used to upload the received cargo status data to the cloud server through the vehicle terminal.

[0053] Wherein, the password verification module specifically includes: The first locking module is used to trigger the locking mechanism when the number of consecutive incorrect password inputs by the user reaches a predetermined threshold.

[0054] The second locking module is used to trigger the locking mechanism when the user enters the password outside the specified time.

[0055] Wherein, the data transmission module includes a wake-up instruction trigger unit; the wake-up instruction trigger unit includes: The electronic seal status change subunit is used to receive the electronic seal status change notification sent by the vehicle-mounted terminal.

[0056] The environmental parameter detection subunit is used to detect that the sudden change value of the environmental parameter inside the vehicle compartment exceeds a preset threshold.

[0057] Wherein, the transmission strategy module includes a data transmission strategy unit; the data transmission strategy unit includes: The first frequency sending subunit is used for sending the real-time collected cargo status data at the first frequency by the Internet of Things transceiver module when the electronic seal is opened.

[0058] The second frequency storage subunit is used for switching the Internet of Things transceiver module to the second frequency to store the cargo status data when the electronic seal is not opened; the second frequency is lower than the first frequency.

[0059] The data uploading module includes an ambient temperature uploading unit, an ambient humidity uploading unit, an air pressure uploading unit, a cargo position information uploading unit, a cargo vibration status uploading unit and a cargo image information uploading unit.

[0060] In some embodiments, Figure 2 As shown, the electronic seal is installed outside the confined space such as the carriage to lock the carriage. The password set by the cloud server can be received through the vehicle terminal, and it can be opened according to the correct password.

[0061] The IoT sensor is placed inside the closed space, close to the cargo, and can monitor the cargo status in real time, including parameters such as temperature, humidity, and air pressure, and dynamically collect relevant data on the cargo status in the container. The transceiver module of the sensor is responsible for communication between the vehicle terminals and sends signals under specific conditions. This module can not only receive data from the sensor, but also has the function of temporarily storing data. Once the transceiver module receives the electronic seal opening signal from the vehicle terminal, it will send data to the vehicle terminal at a preset frequency until the data is successfully transmitted to the cloud server by the vehicle terminal. As the core device for signal conversion and data relay, the vehicle terminal can effectively communicate with the transceiver module of the sensor, the electronic seal, and the cloud server.

[0062] To illustrate with an example, in the process of cold chain transportation, some truck drivers will turn off the refrigeration system in the car after the goods leave the warehouse in order to reduce fuel consumption during transportation, and then restart the refrigeration when arriving at the destination, in order to quickly reduce the temperature. Although this practice may save some fuel costs, it seriously violates the standards of cold chain transportation and may cause damage to the quality of the goods. The method proposed in this application uses an Internet of Things sensor to monitor the temperature in the car throughout the process; once the electronic seal is opened, the stored cargo status data will be immediately transmitted to the cloud server. After analysis by the cloud server, if the temperature data is abnormal, the system will immediately send a warning message to the relevant staff so that corresponding measures can be taken in time, and the transportation personnel will be held accountable, thereby preventing unnecessary cargo losses and related disputes.

[0063] In summary, this application has the following technical effects: This application effectively solves the problem of being unable to collect data in confined spaces and being unable to supervise process quality through steps such as dynamic password verification, awakening the IoT transceiver module and adjusting the data transmission strategy, and data storage and analysis on a cloud server.

[0064] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The description of the above embodiments is only used to help understand the method and core ideas of this application. At the same time, for those skilled in the art, according to the ideas of this application, there will be changes in the specific implementation methods and application scope.
