Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted environment monitoring, and particularly to an intelligent control system and method based on vehicle-mounted environment monitoring. Background Art

[0002] A vehicle-mounted environment monitoring system is a system that monitors the environment inside a container in real time through multiple sensors during vehicle transportation; these systems usually include air quality monitoring (such as PM2.5, CO2 concentration), temperature and humidity detection, window fog monitoring, etc. Existing vehicle-mounted environment monitoring systems mainly collect and analyze sensor data to provide real-time feedback to users and respond accordingly to the transportation status of the vehicle during transportation in a timely manner to ensure safety during transportation.

[0003] During the actual vehicle transportation process, if the vehicle-mounted environment monitoring system inside the container is not set up reasonably, it may lead to the inability to provide users with efficient and reliable vehicle-mounted environment monitoring, which may affect the safety of the vehicle-mounted environment; in addition, if the vehicle-mounted environment data inside the container cannot be reasonably received and analyzed, it may lead to conflicts in environmental data, easily causing users to make wrong decisions about the vehicle transportation status, affecting the safety of goods or transportation efficiency. Summary of the Invention

[0004] The object of the present invention is to solve the above-mentioned problems and provide an intelligent control system and method based on vehicle-mounted environment monitoring.

[0005] In the first aspect of the implementation of the present invention, an intelligent control method based on vehicle-mounted environment monitoring is first proposed. The method includes: Set up data collectors in each container to collect the environmental data inside the container in real time; Obtain the communication connection status between each data collector and the terminal handheld device, and determine whether the environmental data inside the container collected by each data collector can be transmitted to the terminal handheld device according to the communication connection status; If the environmental data collected by each data collector can be transmitted to the terminal handheld device, calculate the priority transmission value of the environmental data collected by each data collector, and transmit the environmental data inside the container collected by each data collector to the terminal handheld device according to the priority transmission value; The terminal handheld device controls the transportation status of the container according to the environmental data inside the container collected by each data collector received; If the environmental data collected by each data collector cannot be transmitted to the terminal handheld device, the environmental data inside the container collected by each data collector is temporarily stored in each data collector, and it is determined whether the terminal handheld device needs to control the transportation status of the container according to the state of the environmental data temporary storage.

[0006] Optionally, a number of data collectors are arranged inside the container to collect the environmental data inside the container in real time, specifically including: Each data collector integrates a rechargeable battery inside. When there is no external power supply, the data collector is independently powered by the internal battery, and the data collector can continuously operate for no less than 0.5 years when fully charged; when there is an external power supply, the data collector can operate simultaneously and charge the rechargeable battery integrated inside; After the data collector is started, it can perform distributed measurements on the temperature, humidity, air pressure and vibration parameters inside the container; and the data collector is applicable to the working temperature range of -40°C to 60°C and the humidity range of 0 to 95%RH; Each data collector is equipped with a non-volatile memory inside, and the collected environmental data is stored after being encrypted; and the data collector adopts a cyclic recording method, records data at 4-hour intervals, and can continuously store data for no less than 180 days; the data will not be lost after the data collector loses power, and the storage duration is no less than ten years; The data collectors of each container are connected to the handheld terminal device, and through a wireless transmission method, the handheld terminal device can read and delete all environmental data of the data collectors of each container; The mean time between failures of each data collector is not less than 3000 hours, and a hardware watchdog is integrated inside.

[0007] Optionally, the steps to determine whether the environmental data inside the container collected by each data collector can be transmitted to the terminal handheld device according to the communication connection status information are as follows: The terminal handheld device sends a transmission instruction for collecting environmental data to each data collector and records the response time of each data collector; If the response time is less than the preset maximum response time threshold, it means that the connection status between the corresponding data collector and the terminal handheld device is good. At this time, the environmental data inside the container collected by the corresponding data collector can be transmitted to the terminal handheld device; then calculate the priority transmission value of the environmental data collected by each data collector, and transmit the environmental data inside the container collected by each data collector to the terminal handheld device according to the priority transmission value; If the response time is not less than the preset maximum response time threshold, it means that the connection status between the corresponding data collector and the terminal handheld device is not good, then the environmental data inside the container collected by each data collector is temporarily stored in each data collector, and it is determined whether the terminal handheld device needs to control the transportation status of the container according to the status of the environmental data temporary storage.

[0008] Optionally, the steps to calculate the priority transmission value of the environmental data collected by each data collector and transmit the environmental data inside the container collected by each data collector to the terminal handheld device according to the priority transmission value are as follows: Obtain the preset importance value of the goods loaded in the container corresponding to the environmental data collected by each data collector, and perform normalization processing on the preset importance value, mapping it to the interval of 0-1 to obtain the goods importance score; Obtain the full-load memory capacity and the used memory capacity of the non-volatile memory in each data collector, subtract the used memory capacity from the full-load memory capacity to obtain the remaining memory capacity, and divide the remaining memory capacity by the full-load memory capacity to obtain the remaining storage space score; Divide the response time of each data collector by the preset maximum response time threshold to obtain the response time score; Calculate the priority transfer value of the environmental data collected by each data collector according to the goods importance score, the remaining storage space score, and the response time score, and transfer the environmental data collected by each data collector in the container to the terminal handheld device according to the priority transfer value. The terminal handheld device controls the transportation status of the container according to the environmental data collected by each data collector received.

[0009] Optionally, the step of calculating the priority transfer value of the environmental data collected by each data collector according to the goods importance score, the remaining storage space score, and the response time score is: F = xc + xz - xr, where F is the priority transfer value, and xc, xz, and xr are the goods importance score, the response time score, and the remaining storage space score respectively; The step of the terminal handheld device controlling the transportation status of the container according to the environmental data collected by each data collector received is: If the terminal handheld device detects that any of the environmental data of the container uploaded by each data collector is not within the corresponding preset range, it issues a corresponding alarm signal and immediately stops the transportation of the corresponding container; If the terminal handheld device detects that the environmental data of the container uploaded by each data collector are all within the corresponding preset range, the corresponding container continues to be transported.

[0010] Optionally, the step of determining whether the terminal handheld device needs to control the transportation status of the container according to the temporary storage status of the environmental data is: Each data collector sends an environmental data transfer request to the terminal handheld device at a preset interval time and sets the upper limit number of transmissions. If the terminal handheld device does not respond to the environmental data transfer request of the data collector within the upper limit number of transmissions, it means that the temporary storage status is not good, and it issues a corresponding alarm signal and immediately stops the transportation of the corresponding container; If within the upper limit of the number of transmissions, the terminal handheld device does not respond to the environmental data transfer request of the data collector, it indicates that the temporary storage state is good. After the data collector uploads the environmental data with a good connection state between the data collector and the terminal handheld device, the environmental data of each data collector that has been responded to by the current terminal handheld device is uploaded to the terminal handheld device. The terminal handheld device controls the transportation state of the container according to the environmental data of the container collected by each data collector received.

[0011] Optionally, the step of uploading the environmental data of each data collector that has been responded to by the current terminal handheld device to the terminal handheld device is as follows: Obtain the total number of times the terminal handheld device responds to each data collector, and upload the environmental data of each data collector to the terminal handheld device in ascending order of the total number of times.

[0012] In the second aspect of the implementation of the present invention, an intelligent control system based on vehicle-mounted environmental monitoring is proposed. The system includes: Data collector module: A data collector is set in each container to collect the environmental data in the container in real time. Judgment module: Obtain the communication connection state between each data collector and the terminal handheld device, and judge whether the environmental data of the container collected by each data collector can be transmitted to the terminal handheld device according to the communication connection state. Data transfer module: If the environmental data of each data collector can be transmitted to the terminal handheld device, calculate the priority transfer value of the environmental data collected by each data collector, and transfer the environmental data of the container collected by each data collector to the terminal handheld device according to the priority transfer value. First monitoring and control module: The terminal handheld device controls the transportation state of the container according to the environmental data of the container collected by each data collector received. Second monitoring and control module: If the environmental data of each data collector cannot be transmitted to the terminal handheld device, the environmental data of the container collected by each data collector is temporarily stored in each data collector, and it is determined whether the terminal handheld device needs to control the transportation state of the container according to the state of the environmental data temporary storage.

[0013] The beneficial effects of the present invention: The present invention provides an intelligent control system and method based on on-vehicle environment monitoring. By setting data collectors in each container, the environmental data inside the container is collected in real time; and the communication connection status between each data collector and the terminal handheld device is obtained, and it is determined whether the environmental data inside the container collected by each data collector can be transmitted to the terminal handheld device according to the communication connection status; if the environmental data inside the container collected by each data collector can be transmitted to the terminal handheld device, the priority transmission value of the environmental data collected by each data collector is calculated, and the environmental data inside the container collected by each data collector is transmitted to the terminal handheld device according to the priority transmission value; the terminal handheld device controls the transportation status of the container according to the environmental data inside the container collected by each data collector received; if the environmental data inside the container collected by each data collector cannot be transmitted to the terminal handheld device, the environmental data inside the container collected by each data collector is temporarily stored in each data collector, and it is determined whether the terminal handheld device needs to control the transportation status of the container according to the status of the environmental data temporarily stored; in this way, during the actual vehicle transportation process, the on-vehicle environment monitoring system inside the container can be reasonably set, which can provide efficient and reliable on-vehicle environment monitoring for users, and can reduce the impact on the safety of the on-vehicle environment; in addition, the on-vehicle environmental data inside the container can be reasonably received and analyzed, without causing conflicts in environmental data, ensuring that users make correct decisions regarding the vehicle transportation status and not affecting the safety of goods or transportation efficiency.

[0017] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] The embodiment of the present invention provides an intelligent control method based on on-vehicle environment monitoring. Refer to Figure 1 , Figure 1The flowchart of an intelligent control method based on vehicle-mounted environment monitoring provided by an embodiment of the present invention. The method includes the following steps: Set data collectors in each container to collect the environmental data in the container in real time; Obtain the communication connection status between each data collector and the terminal handheld device, and determine whether the environmental data in the container collected by each data collector can be transmitted to the terminal handheld device according to the communication connection status; If the environmental data collected by each data collector can be transmitted to the terminal handheld device, calculate the priority transmission value of the environmental data collected by each data collector, and transmit the environmental data in the container collected by each data collector to the terminal handheld device according to the priority transmission value; The terminal handheld device controls the transportation status of the container according to the environmental data in the container collected by each data collector; If the environmental data collected by each data collector cannot be transmitted to the terminal handheld device, the environmental data in the container collected by each data collector is temporarily stored in each data collector, and it is determined whether the terminal handheld device needs to control the transportation status of the container according to the status of the temporary storage of the environmental data.

[0019] Based on an intelligent control method based on vehicle-mounted environment monitoring provided by an embodiment of the present invention, during the actual vehicle transportation process, the vehicle-mounted environment monitoring system in the container can be reasonably set, which can provide efficient and reliable vehicle-mounted environment monitoring for users, and can reduce the impact on the safety of the vehicle-mounted environment; in addition, the vehicle-mounted environment data in the container can be reasonably received and analyzed, which will not cause conflicts in environmental data, ensure that users make correct decisions about the vehicle transportation status, and will not affect the cargo safety or transportation efficiency.

[0020] In one embodiment, several data collectors are set in the container, and the specific steps of collecting the environmental data in the container in real time include: Each data collector integrates a rechargeable battery inside. When there is no external power supply, the data collector is independently powered by the internal battery, and the data collector can continuously operate for no less than 0.5 years when fully charged; when there is an external power supply, the data collector can operate simultaneously and charge the rechargeable battery integrated inside; After the data collector is started, it can perform distributed measurement on the temperature, humidity, air pressure and vibration parameters inside the container; and the data collector is applicable to the working temperature range of -40°C to 60°C and the humidity range of 0 to 95%RH; Each data collector is equipped with a non-volatile memory inside, and the collected environmental data is stored after being encrypted; and the data collector adopts a cyclic recording method, records data at 4-hour intervals, and can continuously store data for no less than 180 days; the data will not be lost after the data collector loses power, and the storage duration is no less than ten years; The data collectors of each container are connected to the handheld terminal device, and through wireless transmission, the handheld terminal device can read and delete all environmental data of the data collectors of each container. The mean time between failures of each data collector is not less than 3000 hours, and an internal integrated hardware watchdog is provided.

[0021] It should be noted that specifically, in terms of battery and power management: Rechargeable battery power supply: Each data collector integrates a rechargeable battery. When there is no external power supply, it relies on the internal battery for independent power supply, and can continuously operate for no less than 0.5 years when fully charged, ensuring long-term independent working ability, which is suitable for scenarios where it is not easy to access external power such as long-distance transportation or cross-border transportation. External power supply charging function: When an external power supply is available, the data collector can not only operate normally, but also charge the internal battery to ensure sufficient battery power and provide stable power guarantee for long-term transportation monitoring.

[0022] Environmental data collection and measurement: Environmental parameter monitoring: The data collector can distributively measure environmental parameters such as temperature, humidity, air pressure and vibration. These parameters are crucial for monitoring the cargo environment inside the container (especially perishable and fragile goods). The system can provide real-time feedback on environmental changes during transportation and take timely measures to address potential risks. Adapt to a wide range of working conditions: The data collector can work normally in the temperature range of -40°C to 60°C and the humidity range of 0 to 95%RH, enabling it to operate stably under various extreme climate conditions.

[0023] Data storage and security: Non-volatile storage: The data collector is equipped with non-volatile memory inside to ensure that data will not be lost in case of power failure. The encrypted stored environmental data further guarantees data security and prevents external tampering or leakage. Circular recording and long-term storage: The data collector adopts a circular recording method, records data every 4 hours, and can continuously store data for no less than 180 days. This means that even in case of communication failures or external connection problems, the data can still be properly retained. The storage duration is not less than ten years to ensure that long-term storage requirements are not a problem.

[0024] Wireless communication and data operation: Wireless data transmission: The data collector is connected to the handheld terminal device through wireless transmission, enabling users to remotely read the data inside the container. This wireless communication method provides a flexible operation method, especially suitable for occasions that require mobile or remote operation.

[0025] Data Reading and Deletion Function: The handheld terminal device can not only read the environmental data collected by the data collector but also perform deletion operations, which provides greater flexibility for data management and update.

[0026] High Reliability and Fault Prevention: High Mean Time Between Failures (MTBF): The average MTBF of the data collector is not less than 3000 hours, which means that the probability of the device failing during long-term operation is extremely low, enhancing the reliability of the system.

[0027] Watchdog Function: An internal integrated hardware watchdog is used to monitor the device's status and automatically restart the device when an anomaly occurs, ensuring that the data collector is always in working condition and preventing data loss or long-term downtime caused by system crashes or failures.

[0028] In one implementation, through the above-set vehicle-mounted environmental monitoring system, it is possible to ensure that the data collector operates stably and efficiently under various environmental conditions, while having powerful data storage, security, and remote operation capabilities; the cargo environment inside the container can be monitored in real time and timely feedback can be obtained, ensuring that key factors such as temperature, humidity, and vibration can be effectively managed during transportation, reducing risks and losses during transportation. In addition, the high reliability and long-term storage capacity of the system greatly improve the credibility of transportation data, facilitating subsequent traceability and analysis; furthermore, each data collector internally integrates a hardware watchdog to ensure the stable operation of the system and data security; and the compact form factor makes it easy to install and use in the vehicle-mounted environment, providing users with an efficient and reliable vehicle-mounted environmental monitoring solution.

[0029] In one embodiment, the steps for determining whether the environmental data of the container collected by each data collector can be transmitted to the terminal handheld device according to the communication connection status information are as follows: The terminal handheld device sends a transmission instruction for collecting environmental data to each data collector and records the response time of each data collector. If the response time is less than the preset maximum response time threshold, it indicates that the connection status between the corresponding data collector and the terminal handheld device is good. At this time, the environmental data of the container collected by the corresponding data collector can be transmitted to the terminal handheld device; then calculate the priority transmission value of the environmental data collected by each data collector, and transmit the environmental data of the container collected by each data collector to the terminal handheld device according to the priority transmission value. If the response time is not less than the preset maximum response time threshold, it indicates that the connection status between the corresponding data collector and the terminal handheld device is not good. Then the environmental data of the container collected by each data collector is temporarily stored in each data collector, and it is determined whether the terminal handheld device needs to control the transportation status of the container according to the status of the temporarily stored environmental data.

[0030] It should be noted that the preset maximum response time threshold is set by professionals according to the actual situation, and specific details are not limited and will not be elaborated here.

[0031] In one implementation method, this solution based on communication status judgment and priority transmission mechanism has several significant advantages. First of all, by real-time monitoring the response time of the data collector, the stability of the communication connection can be accurately judged, so as to ensure the timely transmission of important environmental data under good network conditions. In this way, the terminal device can obtain key data in a timely manner, such as temperature and humidity changes, abnormal air pressure, etc., and can quickly take necessary adjustment measures to ensure the transportation safety of the goods in the container. When the communication connection is poor, the data will not be lost, and the temporary storage mechanism ensures the integrity of the data. Even if the transmission is delayed, the environmental data can still be successfully transmitted when the connection is restored later, avoiding incorrect decisions caused by information loss. In addition, by introducing a calculation mechanism for the priority transmission value, differential processing can be carried out according to the importance and urgency of the environmental data, ensuring that the most critical data can be transmitted to the terminal device first, thus avoiding potential risks of untimely response caused by transmission delays. This method effectively improves the reliability and stability of the system, especially in complex transportation environments with unstable networks, ensuring the continuity and effectiveness of environmental monitoring data, and providing strong data support for safety management and timely decision-making during the transportation process. At the same time, through real-time control and response, the transportation risks caused by environmental anomalies are reduced, and the safety of the goods is improved.

[0032] In one embodiment, the steps of calculating the priority transmission value of the environmental data collected by each data collector and transmitting the environmental data collected by each data collector in the container to the terminal handheld device according to the priority transmission value are as follows: Obtain the preset importance value of the goods loaded in the container corresponding to the environmental data collected by each data collector, and perform normalization processing on the preset importance value, mapping it to the interval of 0-1 to obtain the goods importance score; Obtain the full-load memory capacity and the used memory capacity of the non-volatile memory in each data collector, subtract the used memory capacity from the full-load memory capacity to obtain the remaining memory capacity, and divide the remaining memory capacity by the full-load memory capacity to obtain the remaining storage space score; Divide the response time of each data collector by the preset maximum response time threshold to obtain the response time score; Calculate the priority transmission value of the environmental data collected by each data collector according to the goods importance score, the remaining storage space score and the response time score, transmit the environmental data collected by each data collector in the container to the terminal handheld device according to the priority transmission value, and the terminal handheld device controls the transportation status of the container according to the environmental data collected by each data collector received.

[0033] It should be noted that the data acquisition methods involved in the above calculations mainly rely on data collectors and environmental monitoring devices inside the container. First, the preset importance value of the goods is usually obtained through predefined goods classification criteria or transportation contracts, usually provided by the shipper or transportation company, and can be configured and adjusted before transportation. Secondly, the data collector will monitor the environmental data inside the container in real time, including parameters such as temperature, humidity, air pressure, and vibration. These data are accurately measured by built-in sensors and uploaded in real time. In addition, the data collector will continuously monitor its storage status, including the used memory capacity and the remaining memory capacity, which are provided by the built-in storage management module. As for the acquisition of the response time, the system sends a collection instruction through a terminal handheld device and records the response time of the data collector each time, so as to calculate the response time score. All these data are transmitted to the terminal device in real time through wireless communication technologies (such as Wi-Fi, Bluetooth, or other low-power communication protocols) for subsequent calculation of the priority transfer value and transportation status control. Therefore, data acquisition not only depends on various sensors and storage modules inside the container, but also combines real-time communication technologies to ensure the timely collection and accurate transmission of data.

[0034] It should be noted that the goods importance score, the remaining storage space score, and the response time score represent the weights of three key factors respectively, which jointly determine the priority of data transmission. The goods importance score is a quantitative assessment of the importance of the goods inside the container. Generally speaking, important goods (such as perishable goods or valuable items) require higher-priority monitoring to ensure that the environmental conditions during transportation can be supervised in a timely and effective manner. If the goods importance score is high, it means that the goods have higher requirements for transportation safety and quality, so it is necessary to give priority to processing the relevant environmental data. The remaining storage space score reflects whether the storage capacity of the data collector is sufficient. If the remaining storage space is small, it means that the data collector may not be able to store more environmental data for a long time. At this time, it is necessary to transfer data first to avoid data loss or overwriting. The response time score reflects the connection status between the data collector and the terminal device. The shorter the response time, the better the communication quality between the data collector and the terminal device, and the faster the data transmission speed. In this case, the larger the response time (that is, the more stable the connection state), the greater the possibility of data transmission, so it is necessary to transmit data first.

[0035] In one implementation, when the importance score of the goods is higher, it indicates that the goods require more real-time attention and protection, so their data needs to be transmitted first. When the remaining storage space score is lower, it means that the data storage space is tight, and the environmental data needs to be uploaded first to prevent loss. A higher response time score indicates that the system connection is stable, the data transmission efficiency is high, and more data can be transmitted quickly. Therefore, considering these factors comprehensively, transmitting data first can ensure the timely feedback of environmental data and guarantee the safety and quality of goods transportation.

[0036] In one embodiment, the steps for calculating the priority transmission value of the environmental data collected by each data collector according to the importance score of the goods, the remaining storage space score, and the response time score are as follows: F = xc + xz - xr, where F is the priority transmission value, and xc, xz, and xr are the importance score of the goods, the response time score, and the remaining storage space score respectively; The steps for the terminal handheld device to control the transportation status of the container according to the environmental data collected by each data collector are as follows: If the terminal handheld device detects that any of the environmental data of the container uploaded by each data collector is not within the corresponding preset range, it will issue a corresponding alarm signal and immediately stop the transportation of the corresponding container; If the terminal handheld device detects that the environmental data of the container uploaded by each data collector is within the corresponding preset range, the corresponding container will continue to be transported.

[0037] It should be noted that the formula F = xc + xz - xr for calculating the priority transmission value of the environmental data collected by each data collector according to the importance score of the goods, the remaining storage space score, and the response time score is designed to comprehensively measure the impact of different factors on the priority of data transmission. "xc" in the formula represents the importance score of the goods, which is usually determined according to the nature of the goods, transportation requirements, and risk assessment. For example, the "xc" value of perishable or valuable goods will be very high, which means that these goods need to be monitored and transmitted more timely; "xz" represents the response time score, which reflects the communication delay between the data collector and the terminal device. The shorter the response time, the higher the score, indicating that the data transmission is faster; "xr" represents the remaining storage space score. If the remaining storage space is less, it means that the ability of the data collector to store environmental data is close to saturation, so the data needs to be transmitted as soon as possible to avoid loss. The less the storage space, the higher the score. In this case, by combining these scores, it is possible to reasonably determine which data collector's environmental data should be transmitted to the terminal device first, so as to ensure timely response and processing of key environmental factors during the container transportation process.

[0038] After the terminal handheld device receives the environmental data from each data collector, it will judge the transportation status of the container based on this data. If any of the environmental parameters in the data exceeds the preset normal range (such as too high temperature, too high humidity or abnormal air pressure), the system will immediately send an alarm signal and stop the transportation of the corresponding container to prevent possible damage or danger. The system will remind the operator to take measures through the alarm. On the contrary, if all the monitored data are within the preset normal range (such as the temperature, humidity and air pressure are all within the safe range), the container can continue to be transported to ensure the smooth progress of the transportation process. Through this mechanism, the terminal handheld device can monitor the environmental conditions inside the container in real time, quickly respond when abnormalities occur, reduce potential transportation risks, and ensure the safety of the goods.

[0039] In one embodiment, if the environmental data of the container collected by each data collector cannot be transmitted to the terminal handheld device, the environmental data collected by each data collector is temporarily stored in each data collector, and the steps to determine whether the terminal handheld device needs to control the transportation status of the container according to the temporary storage status of the environmental data are as follows: Each data collector sends an environmental data transfer request to the terminal handheld device at preset intervals and sets the upper limit of the number of transmissions. If the terminal handheld device does not respond to the environmental data transfer request of the data collector within the upper limit of the number of transmissions, it means that the temporary storage status is not good, and a corresponding alarm signal is sent to immediately stop the transportation of the corresponding container; If the terminal handheld device does not respond to the environmental data transfer request of the data collector within the upper limit of the number of transmissions, it means that the temporary storage status is good. After the environmental data of the data collectors with good connection status between the data collector and the terminal handheld device is uploaded, the environmental data of each data collector responded by the current terminal handheld device is uploaded to the terminal handheld device; The terminal handheld device controls the transportation status of the container according to the environmental data of the container collected by each data collector received.

[0040] In one embodiment, the steps to upload the environmental data of each data collector responded by the current terminal handheld device to the terminal handheld device are as follows: Obtain the total number of times the terminal handheld device responds to each data collector, and upload the environmental data of each data collector to the terminal handheld device in ascending order of the total number of times.

[0041] It should be noted that in the case where the environmental data of each data collector cannot be transmitted to the terminal handheld device in a timely manner, the system adopts a method of temporary storage and polling to ensure the effective transmission and monitoring of environmental data during the container transportation process. In the specific steps, the data collector will actively send an environmental data transmission request to the terminal handheld device at a preset interval, and a transmission upper limit number will be set for the request of each data collector. This means that if the terminal device fails to respond within the specified number of times, the system will send an alarm signal and immediately stop the transportation of the container. This is to prevent potential safety hazards that may be brought about by continued transportation in the event of a communication interruption, especially when transporting important or vulnerable goods, and the inability to obtain real-time environmental data may lead to the failure to take appropriate emergency measures in a timely manner. If the terminal device successfully responds to the request of the data collector within the upper limit number of times, the data collector will upload the environmental data according to the connection status. For data collectors with good connection status, the data will be immediately uploaded to the terminal device. Once the terminal device receives the environmental data transmitted by the data collector, it will perform real-time control on the transportation status of the container based on this data to ensure the safety of the transportation process. The response mechanism of the terminal handheld device is very crucial. By counting the number of responses, it will preferentially upload the data of the data collector with fewer response times. The purpose of doing this is to ensure that the environmental data can be obtained from the devices that have not uploaded data as soon as possible, and to prevent information lag caused by some data collectors failing to transmit data in a timely manner. For example, if a data collector fails to upload data due to communication problems, its response times will be fewer, so the system will preferentially upload the data of this collector to the terminal device, thus ensuring that a complete environmental monitoring information can be obtained as quickly as possible in the system.

[0042] The advantage of this mechanism is that even in the case of unstable communication, the system can still ensure that the most important environmental data is preferentially processed and transmitted, so as to respond to the transportation status of the container in a timely manner and ensure the safety of the transportation process.

[0043] In one implementation method, through the above method, during the actual vehicle transportation process, the in-vehicle environmental monitoring system in the container can be reasonably set, which can provide efficient and reliable in-vehicle environmental monitoring for users and reduce the impact on the safety of the in-vehicle environment; in addition, the in-vehicle environmental data in the container can be reasonably received and analyzed, without causing conflicts in environmental data, ensuring that users can make correct decisions regarding the vehicle transportation status and not affecting the cargo safety or transportation efficiency.
