Description

TECHNICAL FIELD

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

[0002] The vehicle-mounted environment monitoring system is a system for monitoring the environment in a container in real time during vehicle transportation through various sensors; these systems usually include air quality monitoring (such as PM2.5, CO2 concentration), temperature and humidity detection, vehicle window fog monitoring, etc. The existing vehicle-mounted environment monitoring system mainly collects and analyzes sensor data to provide real-time feedback for users, and timely responds to the transportation state of the vehicle during transportation to ensure the safety during transportation.

[0003] In actual vehicle transportation, if the vehicle-mounted environment monitoring system in the container is not reasonably set, it may not provide efficient and reliable vehicle-mounted environment monitoring for users, and may affect the safety of the vehicle-mounted environment. In addition, if the vehicle-mounted environment data in the container cannot be reasonably received and analyzed, it may cause conflicts in the environment data, which may easily lead users to make wrong decisions about the transportation state of the vehicle, affecting the safety of goods or transportation efficiency. SUMMARY

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

[0005] In the first aspect of the present application, an intelligent control method based on vehicle-mounted environment monitoring is first proposed, which comprises:

[0018] 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;

[0019] If the response time is less than a preset maximum response time threshold, it indicates that the connection state between the corresponding data collector and the terminal handheld device is good, and at this time, the environmental data in the container collected by the corresponding data collector can be transmitted to the terminal handheld device; then, a priority transmission value of the environmental data collected by each data collector is calculated, and the environmental data in the container collected by each data collector is transmitted to the terminal handheld device according to the priority transmission value;

[0020] If the response time is not less than the preset longest response time threshold, it indicates that the connection state between the corresponding data collector and the terminal handheld device is not good, the environmental data in the container collected by each data collector is temporarily stored in each data collector, and whether the terminal handheld device needs to control the transportation state of the container is determined according to the temporary storage state of the environmental data.

[0027] F=xc+xz-xr, wherein F is the priority transmission value, xc, xz and xr are the goods importance score, the response time score and the storage space remaining score respectively;

[0028] The step of controlling the transportation state of the container by the terminal handheld device according to the received environmental data in the container collected by each data collector is:

[0029] If the terminal handheld device detects that any one of the environmental data uploaded by each data collector in the container is not within the corresponding preset range, a corresponding alarm signal is sent, and the transportation of the corresponding container is immediately stopped;

[0030] If the terminal handheld device detects that the environmental data uploaded by each data collector in the container is within the corresponding preset range, the corresponding container continues to be transported.

[0031] Optionally, the step of determining whether the terminal handheld device needs to control the transportation state of the container according to the state of the environmental data temporarily stored is:

[0032] Each data collector sends an environmental data transmission request to the terminal handheld device at a preset interval time, and sets an upper limit number of times of sending, if the terminal handheld device does not respond to the environmental data transmission request of the data collector within the upper limit number of times of sending, it indicates that the temporary storage state is not good, and a corresponding alarm signal is sent to immediately stop the transportation of the corresponding container;

[0033] If the terminal handheld device does not respond to the environmental data transmission request of the data collector within the upper limit number of times of sending, it indicates that the temporary storage state is good, and after the connection between the data collector and the terminal handheld device is good, the environmental data uploaded by the data collector is uploaded to the terminal handheld device after the current terminal handheld device responds to the environmental data of each data collector;

[0057] In one embodiment, a plurality of data collectors are arranged in the container to collect environmental data in the container in real time, specifically including:

[0058] Each data collector is internally integrated with a rechargeable battery, and 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 not less than 0.5 years under full power; when there is an external power supply, the data collector can operate simultaneously and charge the internally integrated rechargeable battery;

[0059] After the data collector is started, the temperature, humidity, air pressure and vibration parameters in the container can be measured in a distributed manner; and the data collector is suitable for a working temperature range of-40℃ to 60℃ and a humidity range of 0 to 95%RH;

[0060] Each data collector is internally equipped with a non-volatile memory, and the collected environmental data is stored after encryption; and the data collector adopts a cyclic recording mode, records data at an interval of 4 hours, and can continuously store data for not less than 180 days; after the data collector is powered off, the data will not be lost, and the storage time is not less than ten years;

[0061] The data collectors of each container are connected with a handheld terminal device, and through wireless transmission, the handheld terminal device reads and deletes all environmental data of the data collectors of each container;

[0062] The average failure-free time of each data collector is not less than 3000 hours, and the internal hardware watchdog is integrated.

[0063] It should be noted that, specifically, in the battery and power management:

[0064] Rechargeable battery power supply: each data collector is internally integrated with a rechargeable battery, and when there is no external power supply, it is independently powered by the internal battery, and can continuously operate for not less than 0.5 years under full power, ensuring long-term independent working ability, suitable for long-distance transportation or cross-border transportation and other scenarios where external power supply is not easy to access. External power supply charging function: when the external power supply is available, the data collector not only can operate normally, but also can charge the internal battery, ensuring sufficient battery power and providing stable power guarantee for long-term transportation monitoring.

[0065] Environmental data collection and measurement:

[0066] Environmental Parameter Monitoring: The data logger can measure environmental parameters such as temperature, humidity, barometric pressure, and vibration in a distributed manner. These parameters are crucial for monitoring the environment of goods inside the container, especially for perishable and fragile goods. The system can provide real-time feedback on environmental changes during transportation, allowing for timely measures to address potential risks. Wide Range of Operating Conditions: The data logger can operate normally in a temperature range of -40°C to 60°C and a humidity range of 0 to 95% RH, allowing it to function reliably in various extreme weather conditions.

[0067] Data Storage and Security:

[0068] Non-volatile Storage: The data logger is equipped with non-volatile memory, ensuring that data is not lost in the event of power failure. Encrypted storage of environmental data further ensures data security, preventing external tampering or leakage. Cyclic Recording and Long-term Storage: The data logger uses cyclic recording, recording data every 4 hours and storing data continuously for not less than 180 days. This means that even if communication fails or external connection problems occur, data can still be properly preserved. The storage duration is not less than ten years, ensuring that long-term storage requirements are not a problem.

[0069] Wireless Communication and Data Operation: Wireless Data Transmission: The data logger connects with the handheld terminal device through wireless transmission, allowing users to remotely read data inside the container. This wireless communication method provides flexible operation, especially suitable for situations that require mobile or remote operation.

[0070] Data Reading and Deletion Function: The handheld terminal device not only can read the environmental data collected by the data logger, but also can perform deletion operations. This provides higher flexibility for data management and updating.

[0071] High Reliability and Failure Prevention: High Mean Time Between Failures: The mean time between failures (MTBF) of the data logger is not less than 3000 hours, which means that the probability of device failure during long-term operation is extremely low, enhancing the reliability of the system.

[0072] Watchdog Function: The internal hardware watchdog is used to monitor the status of the device and automatically restart it when it encounters abnormalities, ensuring that the data logger is always in working condition and preventing data loss or long-term downtime due to system crashes or failures.

[0073] In one implementation, the aforementioned vehicle-mounted environmental monitoring system ensures stable and efficient operation of the data acquisition unit under various environmental conditions, while possessing robust data storage, security, and remote operation capabilities. The cargo environment within the container can be monitored in real time and feedback can be provided promptly, ensuring effective management of key factors such as temperature, humidity, and vibration during transportation, reducing risks and losses. Furthermore, the system's high reliability and long-term storage capacity significantly enhance the credibility of transportation data, facilitating subsequent traceability and analysis. Additionally, each data acquisition unit integrates a hardware watchdog to ensure stable system operation and data security. Its compact size makes it easy to install and use in vehicle environments, providing users with an efficient and reliable vehicle-mounted environmental monitoring solution.

[0074] In one embodiment, the step of determining whether the environmental data collected by each data collector inside the container can be transmitted to the terminal handheld device based on the communication connection status information is as follows:

[0075] The terminal handheld device sends transmission instructions to each data collector to collect environmental data, and records the response time of each data collector;

[0076] If the response time is less than the preset maximum response time threshold, it indicates that the connection between the corresponding data collector and the terminal handheld device is good. At this time, the environmental data collected by the corresponding data collector inside the container can be transmitted to the terminal handheld device. Then, the priority transmission value of the environmental data collected by each data collector is calculated, and the environmental data collected by each data collector inside the container is transmitted to the terminal handheld device according to the priority transmission value.

[0077] If the response time is not less than the preset maximum response time threshold, it indicates that the connection between the corresponding data collector and the terminal handheld device is not good. In this case, the environmental data collected by each data collector inside the container is temporarily stored in each data collector, and the terminal handheld device is used to determine whether it needs to control the transportation status of the container based on the temporary storage status of the environmental data.

[0078] It should be noted that the preset maximum response time threshold is set by professionals based on actual conditions, and no specific limitations or details are provided.

[0079] In one implementation, this communication state-based judgment and priority transmission mechanism has several significant benefits. First, by monitoring the response time of the data collector in real time, the stability of the communication connection can be accurately determined, ensuring timely transmission of important environmental data in good network conditions. In this way, the terminal device can obtain critical data such as temperature and humidity changes, pressure abnormalities, etc., allowing it to quickly take necessary adjustment measures to ensure the safety of the goods in the container during transportation. When the communication connection is poor, data will not be lost, and the temporary storage mechanism ensures data integrity. Even if transmission is delayed, environmental data can still be transmitted smoothly when the connection is restored later, avoiding potential risks of incorrect decisions due to lost information. In addition, by introducing the priority transmission value mechanism, differential processing can be performed based on the importance and urgency of environmental data, ensuring that the most critical data is transmitted to the terminal device first, thereby avoiding potential risks of delayed transmission. 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, providing strong data support for safety management and timely decision-making during transportation. At the same time, through real-time control and response, transportation risks caused by environmental abnormalities are reduced, improving the safety of goods.

[0080] In one embodiment, the priority transmission value of the environmental data collected by each data collector is calculated, and the environmental data collected by each data collector in the container is transmitted to the terminal handheld device according to the priority transmission value.

[0081] The preset importance value of the goods in the container corresponding to the environmental data collected by each data collector is obtained, and the preset importance value is normalized and mapped to the interval of 0-1 to obtain a goods importance score;

[0082] The full memory capacity and used memory capacity of the non-volatile memory in each data collector are obtained, the full memory capacity is subtracted from the used memory capacity to obtain the remaining memory capacity, and the remaining memory capacity is divided by the full memory capacity to obtain a storage space remaining score;

[0083] The response time of each data collector is divided by the preset maximum response time threshold to obtain a response time score;

[0084] The priority transmission value of the environmental data collected by each data collector is calculated according to the goods importance score, storage space remaining score, and response time score, and the environmental data collected by each data collector in the container is transmitted to the terminal handheld device according to the priority transmission value. The terminal handheld device controls the transportation state of the container according to the received environmental data collected by each data collector in the container.

[0085] It is worth noting that the data acquisition method involved in the above calculation mainly relies on the data collector and the environmental monitoring equipment inside the container. First of all, the preset importance value of the goods is usually obtained through pre-defined goods classification standards or transportation contracts, usually provided by the consignor or the 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 temperature, humidity, air pressure, vibration and other parameters, which are accurately measured by built-in sensors and uploaded in real time. In addition, the data collector will also 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 response time, the system sends collection instructions through the terminal handheld device and records the response time of each data collector, so as to calculate the response time score. All these data are transmitted in real time to the terminal device through wireless communication technology (such as Wi-Fi, Bluetooth or other low-power communication protocols) for subsequent priority transmission value calculation and transportation state control. Therefore, data acquisition not only depends on various sensors and storage modules inside the container, but also combines real-time communication technology to ensure timely data collection and accurate transmission.

[0086] It is worth noting that the goods importance score, the storage space remaining score and the response time score represent the weight of the three key factors respectively, which together determine the priority of data transmission. The goods importance score is a quantitative evaluation of the importance of goods in the container. Generally speaking, important goods (such as perishable goods or valuable items) require higher priority monitoring to ensure that their environmental conditions during transportation can be timely and effectively regulated. If the goods importance score is high, it means that the goods have higher safety and quality requirements for transportation, so the related environmental data needs to be processed first. The storage space remaining 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, so data needs to be transmitted first to avoid data loss or overwrite. 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 (i.e. the more stable the connection status), the greater the possibility of data transmission, so data needs to be transmitted first.

[0087] In one implementation, the greater the cargo importance score, the more real-time attention and protection the cargo needs, and thus its data needs to be transmitted with priority; the smaller the storage space remaining score, the more data storage space is tight, and the environmental data needs to be uploaded in priority to prevent loss; the greater the response time score, the more stable the system connection and the higher the data transmission efficiency, and more data can be transmitted quickly. Therefore, by comprehensively considering these factors, transmitting data with priority can ensure timely feedback of environmental data and guarantee the safety and quality of cargo transportation.

[0088] In one embodiment, the step of calculating the priority transmission value of the environmental data collected by each data collector according to the cargo importance score, the storage space remaining score, and the response time score is:

[0089] F = xc + xz - xr, where F is the priority transmission value, xc, xz, and xr are the cargo importance score, the response time score, and the storage space remaining score, respectively;

[0090] The step of controlling the transportation state of the container by the terminal handheld device according to the received environmental data of the container collected by each data collector is:

[0091] If the terminal handheld device detects that any one of the environmental data of the container uploaded by each data collector is not within the corresponding preset range, an alarm signal is sent, and the transportation of the corresponding container is immediately stopped;

[0092] If the terminal handheld device detects that all the environmental data of the container uploaded by each data collector is within the corresponding preset range, the corresponding container continues to be transported.

[0093] 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 cargo importance score, the storage space remaining score, and the response time score aims to comprehensively measure the influence of different factors on the priority of data transmission. "xc" in the formula represents the importance score of the cargo, which is usually determined according to the nature of the cargo, transportation requirements, and risk assessment. For example, the "xc" value of perishable goods or valuable items will be high, indicating that these items need more timely monitoring and data transmission; "xz" represents the response time score, reflecting the degree of delay in communication between the data collector and the terminal device. The shorter the response time, the higher the score, indicating faster data transmission; "xr" represents the storage space remaining score. If the remaining storage space is small, it means that the data collector's ability to store environmental data is close to saturation, and thus data needs to be transmitted as soon as possible to prevent loss. The smaller the storage space, the higher the score. In this case, by comprehensively considering these scores, it can be reasonably determined which data collector's environmental data should be transmitted to the terminal device in priority, thereby ensuring timely response and handling of critical environmental factors during container transportation.

[0094] After receiving the environmental data from each data collector, the terminal handheld device determines the transport state of the container according to the data. If any of the environmental parameters in the data exceeds the preset normal range (such as excessively high temperature, excessively high humidity, or abnormal air pressure), the system immediately sends an alarm signal to stop the transport of the corresponding container to prevent possible damage or danger. The system reminds the operator to take measures through the alarm. Conversely, if all the monitored data is within the preset normal range (such as temperature, humidity, and air pressure are within the safe range), the container can continue to be transported to ensure the smooth progress of the transport process. Through this mechanism, the terminal handheld device can monitor the environmental conditions in the container in real time and respond quickly when an abnormality occurs, reducing potential transport risks and ensuring the safety of the goods.

[0095] In one embodiment, if each data collector cannot be delivered to the terminal handheld device, the environmental data of the container collected by each data collector is temporarily stored in each data collector, and the step of determining whether the terminal handheld device needs to control the transport state of the container according to the temporary storage state of the environmental data is:

[0096] Each data collector sends an environmental data delivery request to the terminal handheld device at a preset interval, and sets an upper limit number of times of sending. If the terminal handheld device does not respond to the environmental data delivery request of the data collector within the upper limit number of times of sending, it indicates that the temporary storage state is not good, and an alarm signal is sent to immediately stop the transport of the corresponding container.

[0097] If the terminal handheld device does not respond to the environmental data delivery request of the data collector within the upper limit number of times of sending, it indicates that the temporary storage state is good, and after the environmental data on the data collector in a good connection state between the data collector and the terminal handheld device is uploaded, the environmental data of each data collector that the current terminal handheld device responds to is uploaded to the terminal handheld device.

[0098] The terminal handheld device controls the transport state of the container according to the received environmental data of each data collector collected in the container.

[0099] In one embodiment, the step of uploading the environmental data of each data collector that the current terminal handheld device responds to to the terminal handheld device is:

[0100] The total number of times that the terminal handheld device responds to each data collector is obtained, and the environmental data of each data collector is uploaded to the terminal handheld device in order from small to large according to the total number of times.

[0101] 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 time, the system adopts the way of temporary storage and polling to ensure the effective transmission and monitoring of the environmental data in 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 predetermined interval, and the request of each data collector will set an upper limit number of times. This means that if the terminal device fails to respond within the specified number of times, the system will issue an alarm signal and immediately stop the transportation of the container. This is to prevent the security risks that may be caused by continued transportation in the case of communication interruption, especially when transporting important or fragile goods, the inability to obtain real-time environmental data may result in the inability to take appropriate emergency measures in time.

[0102] 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 state. For data collectors with good connection state, 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 control the transportation state of the container in real time according to these data to ensure the safety of the transportation process. The response mechanism of the terminal handheld device is very critical, which will prioritize the data of the data collector with fewer response times. The purpose of this is to ensure that environmental data is obtained from devices that have not uploaded data as soon as possible, to prevent information lag caused by some data collectors failing to transmit data in time. For example, if a data collector fails to upload data due to communication problems, its response times will be less, so the system will prioritize uploading the data of this collector to the terminal device, thereby ensuring that complete environmental monitoring information is obtained as quickly as possible in the system.

[0103] 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 prioritized and transmitted, so that the transportation state of the container can be responded to in time, ensuring the safety of the transportation process.

[0104] In one implementation, through the above-mentioned way, in the actual vehicle transportation process, the vehicle-mounted environmental monitoring system in the container can be reasonably set, efficient and reliable vehicle-mounted environmental monitoring can be provided for users, and the impact on the safety of the vehicle-mounted environment can be reduced; in addition, the vehicle-mounted environmental data in the container can be reasonably received and analyzed, without causing conflicts of environmental data, ensuring that users make correct decisions about the transportation state of the vehicle, and without affecting the safety of goods or transportation efficiency.

[0109] A first monitoring control module: the terminal handheld device controls the transportation state of the container according to the environmental data in the container collected by each data collector;

[0110] A second monitoring control module: if 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 state of the container according to the temporary storage state of the environmental data.
