Technical Field

[0001] This invention relates to the field of marine technology, and more specifically, to a remote monitoring method, device, system, and electronic equipment for refrigerated containers. Background Technology

[0002] In related technologies, once a refrigerated container is loaded onto a ship, the electrician needs to immediately plug in and start the refrigeration unit. During long-distance transoceanic transport, which can last up to a month or even longer, the electrician needs to check the refrigeration system twice daily, morning and evening, to ensure it is functioning properly. Simultaneously, they must record various environmental data, such as container temperature and ventilation, and then generate electronic data, which is then sent remotely to the shore-based monitoring center by the captain. However, this process is complex, time-consuming, and labor-intensive, and problems may not be detected promptly, making remote real-time monitoring and early warning impossible.

[0004] Therefore, the first aspect of the present invention proposes a method for remote monitoring of refrigerated containers.

[0005] A second aspect of the present invention provides a method for remote monitoring of refrigerated containers.

[0009] The sixth aspect of the present invention provides an electronic device.

[0010] A seventh aspect of the present invention provides a storage medium.

[0011] In view of this, according to a first aspect of the present invention, a remote monitoring method for refrigerated containers is proposed for a shore-based terminal, comprising: receiving first parameter information transmitted by a ship's control device at a preset information transmission frequency via a satellite network, wherein the first parameter information is one or more combinations of environmental parameters of the refrigerated container, equipment status of the refrigerated container, and positioning data of the refrigerated container; matching the first parameter information with preset parameter information to obtain a matching result; determining adjustment information based on the matching result and anomaly warning rules; and transmitting the adjustment information to the ship's control device so that the control device adjusts the parameters of the refrigerated container and the preset information transmission frequency according to the adjustment information.

[0012] The remote monitoring method for refrigerated containers provided by this invention is mainly used in a shore-based terminal located in a shore-based monitoring center. Specifically, it includes: firstly, receiving first parameter information transmitted by the ship's control device at a preset information transmission frequency via a satellite network. This first parameter information refers to the parameter information of the refrigerated container, including environmental parameters, equipment status, and positioning data. This invention receives the first parameter information via a satellite network, ensuring uninterrupted data transmission and enabling long-distance transmission. After obtaining the first parameter information, it is matched with preset parameter information to obtain a matching result. That is, the shore-based terminal compares the first parameter information and the preset parameter information to determine the difference between them and its magnitude. The preset parameter information consists of standard environmental parameters required for the storage and transportation of refrigerated goods. After obtaining the matching result, adjustment information is determined based on the matching result and previously established anomaly warning rules. These anomaly warning rules include multiple matching results and corresponding adjustment information for each matching result. After determining the adjustment information, it is fed back to the ship's control system, enabling the control system to adjust the parameters of the refrigerated container and the preset information transmission frequency accordingly. This invention allows for the timely detection of problems with refrigerated containers from a shore-based monitoring center, achieving remote real-time monitoring and early warning of refrigerated containers.

[0013] In some technical solutions, optionally, the step of determining adjustment information based on the matching result and the abnormal warning rule includes: when the matching result is that the difference between the first parameter information and the preset parameter information is not within the preset range, and the first parameter information is greater than the preset parameter information, the adjustment information is determined to be to increase the preset information sending frequency and decrease the parameters of the refrigerated container; when the matching result is that the difference between the first parameter information and the preset parameter information is not within the preset range, and the first parameter information is less than the preset parameter information, the adjustment information is determined to be to increase the preset information sending frequency and increase the parameters of the refrigerated container.

[0014] In this technical solution, the step of determining adjustment information based on matching results and anomaly warning rules includes: when the difference between the first parameter information and the preset parameter information is not within a preset range, and the first parameter information is greater than the preset parameter information, it indicates that the refrigerated container has an anomaly. Therefore, the adjustment information is to adjust the preset information transmission frequency to the maximum transmission frequency and decrease the parameters of the refrigerated container, so that the control device, upon receiving the adjustment information, can adjust the preset information transmission frequency to the maximum transmission frequency and control the refrigerated container's parameters to decrease. When the difference between the first parameter information and the preset parameter information is not within a preset range, and the first parameter information is less than the preset parameter information, it indicates that the refrigerated container has an anomaly. Therefore, the adjustment information is to adjust the preset information transmission frequency to the maximum transmission frequency and increase the parameters of the refrigerated container, so that the control device, upon receiving the adjustment information, can adjust the preset information transmission frequency to the maximum transmission frequency and control the refrigerated container's parameters to increase. By determining the adjustment information based on matching results and anomaly warning rules, remote control of the refrigerated container's parameters is achieved, reducing the occurrence of cargo damage.

[0015] In some technical solutions, optionally, after receiving the first parameter information transmitted by the ship's control device via a satellite network at a preset information transmission frequency, the method includes: displaying the first parameter information.

[0018] The remote monitoring method for refrigerated containers provided by this invention is mainly used in ship control devices, where the ship's control devices are installed on the ship. The remote monitoring method for refrigerated containers specifically includes: firstly, acquiring second parameter information collected by a LORA (Long Range Radio) sensor, where the LORA sensor is located inside the refrigerated container, and the second parameter information being the container's parameter information. Further, after obtaining the second parameter information, edge computing processing is performed on it to obtain first parameter information. This edge computing processing includes one or more combinations of data parsing, data filtering, and data filtering. That is, after obtaining the second parameter information, edge computing processing is used to dynamically filter and compress it to obtain the filtered and compressed first parameter information. After obtaining the first parameter information, it is transmitted to a shore-based terminal via a satellite network at a preset information transmission frequency. Transmitting the first parameter information at the preset transmission frequency reduces satellite communication costs, and using a satellite network for data transmission achieves long-distance data transmission. After transmitting the first parameter information to the shore-based terminal, the system receives adjustment information from the shore-based terminal in response to the first parameter information. This adjustment information includes adjustments to the preset information transmission frequency and the parameters of the refrigerated container. Finally, the preset information transmission frequency and the parameters of the refrigerated container are adjusted according to the adjustment information. This enables remote real-time monitoring and early warning of the refrigerated container.

[0020] In this technical solution, the second parameter information can be one or more combinations of the refrigerated container's environmental parameters, equipment status, and location data. By receiving information such as the refrigerated container's environmental parameters, equipment status, and location data collected by the LORA sensor, comprehensive monitoring of the refrigerated container is ensured.

[0021] According to a third aspect of the present invention, a remote monitoring device for a refrigerated container is provided for a shore-based terminal, comprising: a first receiving module, configured to receive first parameter information transmitted by a ship's control device at a preset information transmission frequency via a satellite network, wherein the first parameter information is one or more combinations of environmental parameters of the refrigerated container, equipment status of the refrigerated container, and positioning data of the refrigerated container; a matching module, configured to match the first parameter information with preset parameter information to obtain a matching result; a first processing module, configured to determine adjustment information based on the matching result and anomaly warning rules; and a first transmitting module, configured to transmit the adjustment information to the ship's control device, so that the control device adjusts the parameters of the refrigerated container and the preset information transmission frequency according to the adjustment information.

The remote monitoring device specifically includes a first receiving module, a matching module, a first processing module, and a first transmitting module. The first receiving module can receive first parameter information transmitted by the ship's control device at a preset information transmission frequency via a satellite network. This first parameter information refers to the parameter information of the refrigerated container, including environmental parameters, equipment status, and positioning data. This invention receives the first parameter information via a satellite network, ensuring uninterrupted data transmission and enabling long-distance transmission. After obtaining the first parameter information, the matching module matches it with preset parameter information to obtain a matching result. That is, the shore-based terminal compares the first parameter information with the preset parameter information to determine the difference and its magnitude. The preset parameter information consists of standard environmental parameters required for the storage and transportation of refrigerated goods. After obtaining the matching result, the first processing module can determine adjustment information based on the matching result and previously established anomaly warning rules. These anomaly warning rules include multiple matching results and corresponding adjustment information for each matching result. After determining the adjustment information, the first transmitting module can feed it back to the ship's control device, enabling the control device to adjust the parameters of the refrigerated container and the preset information transmission frequency based on the adjustment information. This invention enables timely detection of problems with refrigerated containers from a shore-based monitoring center, achieving remote real-time monitoring and early warning of refrigerated containers.

[0023] According to a fourth aspect of the present invention, a remote monitoring device for refrigerated containers is provided for use in a ship control device, comprising: a first acquisition module for acquiring second parameter information collected by a long-range radio sensor, wherein the second parameter information is parameter information of the refrigerated container; a second processing module for performing edge computing processing on the second parameter information to obtain first parameter information, wherein the edge computing processing includes one or more combinations of data parsing, data filtering, and data filtering; a second transmission module for transmitting the first parameter information to a shore-based terminal via a satellite network according to a preset information transmission frequency; a second receiving module for receiving adjustment information fed back from the shore-based terminal, wherein the adjustment information corresponds to the first parameter information; and a third processing module for adjusting the parameters of the refrigerated container and the preset information transmission frequency according to the adjustment information.

[0040] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0042] Figure 1 This diagram illustrates one embodiment of a remote monitoring method for refrigerated containers according to the present invention. The remote monitoring method for refrigerated containers is primarily used in shore-based terminals and specifically includes:

[0043] Step 102: Receive first parameter information transmitted by the ship's control device at a preset information transmission frequency via satellite network. The first parameter information is one or more combinations of environmental parameters of the refrigerated container, equipment status of the refrigerated container, and positioning data of the refrigerated container.

[0044] Step 104: Match the first parameter information with the preset parameter information to obtain the matching result;

[0045] Step 106: Determine adjustment information based on the matching results and anomaly warning rules;

[0046] Step 108: Send the adjustment information to the ship's control device so that the control device can adjust the parameters of the refrigerated container and the preset information transmission frequency according to the adjustment information.

[0047] The remote monitoring method for refrigerated containers provided by this invention is mainly used in shore-based terminals located in shore-based monitoring centers. Specifically, it includes: firstly, receiving first parameter information transmitted by the ship's control device at a preset information transmission frequency via a satellite network. This first parameter information refers to the parameter information of the refrigerated container, including environmental parameters, equipment status, and positioning data. Further, the first parameter information is the result of edge computing processing of data collected by sensors from the refrigerated container. The sensors can be LORA (Long Range Radio) sensors. By using LORA sensors to collect the parameter information of the refrigerated container and transmitting it to the ship's control device, the transmission distance is increased, power consumption is reduced, and anti-interference capability is improved compared to related technologies. Simultaneously, this invention receives the first parameter information via a satellite network, ensuring uninterrupted data transmission and enabling long-distance transmission. Furthermore, since the first parameter information is edge-processed and transmitted by the control device at a preset information transmission frequency, dynamic filtering and compression of the data are achieved, reducing satellite communication costs and improving data quality. After obtaining the first parameter information, it is matched with preset parameter information to obtain a matching result. That is, the first parameter information and preset parameter information are compared at the shore-based terminal to determine the difference between them and its magnitude. The preset parameter information consists of standard environmental parameters required for the storage and transportation of refrigerated goods. After obtaining the matching result, adjustment information is determined based on the matching result and previously established anomaly warning rules. These anomaly warning rules include multiple matching results and corresponding adjustment information for each result. Once the adjustment information is determined, it is fed back to the ship's control system. This allows the ship's control system to adjust the parameters of the refrigerated container and the frequency of preset information transmission based on the adjustment information. It can be understood that when the parameters of the refrigerated container, i.e., the first parameter information, are abnormal, in order to determine whether the ship's control system has adjusted the parameters of the refrigerated container, the ship's control system needs to frequently send the first parameter information to the shore-based terminal. Therefore, the preset information transmission frequency needs to be increased to the maximum transmission frequency. When the parameters of the refrigerated container, i.e., the first parameter information, are not abnormal, it is no longer necessary for the ship's control device to frequently send the first parameter information to the shore-based terminal. Therefore, the preset information transmission frequency needs to be reduced to the minimum. Thus, the adjustment information sent by the shore-based terminal to the control device includes the adjustment information for the preset information transmission frequency, enabling the control device to adjust the preset information transmission frequency. This invention enables timely detection of problems with refrigerated containers at the shore-based monitoring center, achieving remote real-time monitoring and early warning of refrigerated containers.

[0048] Figure 2 The diagram illustrates a step in a remote monitoring method for refrigerated containers according to an embodiment of the present invention, specifically the step of determining adjustment information based on matching results and anomaly warning rules. The step of determining adjustment information based on matching results and anomaly warning rules includes:

[0049] Step 202: When the matching result is that the difference between the first parameter information and the preset parameter information is not within the preset range, and the first parameter information is greater than the preset parameter information, determine that the adjustment information is to increase the preset information sending frequency and decrease the parameters of the refrigerated container;

[0050] Step 204: When the matching result is that the difference between the first parameter information and the preset parameter information is not within the preset range, and the first parameter information is less than the preset parameter information, determine that the adjustment information is to increase the preset information sending frequency and increase the parameters of the refrigerated container.

[0051] In this embodiment, the step of determining adjustment information based on the matching result and the anomaly warning rule includes: when the matching result shows that the difference between the first parameter information and the preset parameter information is not within a preset range, and the first parameter information is greater than the preset parameter information, it indicates that the refrigerated container has an anomaly. Therefore, the adjustment information is to adjust the preset information transmission frequency to the maximum information transmission frequency and decrease the parameters of the refrigerated container, so that the control device, after receiving the adjustment information, can adjust the preset information transmission frequency to the maximum information transmission frequency and control the parameters of the refrigerated container to decrease. When the matching result shows that the difference between the first parameter information and the preset parameter information is not within a preset range, and the first parameter information is less than the preset parameter information, it indicates that the refrigerated container has an anomaly. Therefore, the adjustment information is to adjust the preset information transmission frequency to the maximum information transmission frequency and increase the parameters of the refrigerated container, so that the control device, after receiving the adjustment information, can adjust the preset information transmission frequency to the maximum information transmission frequency and control the parameters of the refrigerated container to increase. When the difference between the first parameter information and the preset parameter information is within a preset range, the adjustment information is to keep the refrigerated container parameters unchanged and maintain the preset information transmission frequency or adjust the preset information transmission frequency to the minimum. By determining the adjustment information based on the matching results and anomaly warning rules, remote control of the refrigerated container parameters is achieved, reducing the occurrence of cargo damage.

[0052] In some embodiments, optionally, after receiving the first parameter information transmitted by the ship's control device via a satellite network at a preset information transmission frequency, the method includes: displaying the first parameter information.

[0053] In this embodiment, after receiving the first parameter information transmitted by the ship's control device at a preset information transmission frequency via a satellite network, the process includes: displaying the first parameter information after it is received at the shore-based terminal, so that the owner of the cargo in the refrigerated container and / or the company to which the ship belongs can intuitively see the parameters of the refrigerated container at the shore. Furthermore, when displaying the first parameter information, a change curve of the first parameter information can be generated by combining historical first parameter information, and the change curve can be displayed. Thus, the shore-based terminal can predict the future first parameter information based on the change curve, thereby sending adjustment information to the control device in advance to reduce the occurrence of cargo damage.

[0054] Figure 3 The second schematic flowchart illustrates a remote monitoring method for refrigerated containers according to an embodiment of the present invention; wherein, the remote monitoring method for refrigerated containers is mainly used in ship control devices, and the remote monitoring method for refrigerated containers includes:

[0055] Step 302: Obtain the second parameter information collected by the long-range radio sensor, wherein the second parameter information is the parameter information of the refrigerated container;

[0056] Step 304: Perform edge computing processing on the second parameter information to obtain the first parameter information, wherein the edge computing processing includes one or more combinations of data parsing, data filtering, and data filtering;

[0057] Step 306: Transmit the first parameter information to the shore-based terminal via satellite network according to the preset information transmission frequency;

[0058] Step 308: Receive adjustment information fed back from the shore-based terminal, wherein the adjustment information corresponds to the first parameter information;

[0059] Step 310: Adjust the parameters of the refrigerated container and the preset information transmission frequency according to the adjustment information.

[0060] The remote monitoring method for refrigerated containers provided by this invention is mainly used in ship control devices, where the ship's control devices are installed on the ship. The remote monitoring method specifically includes: firstly, acquiring second parameter information collected by a LORA (Long Range Radio) sensor, where the LORA sensor is located inside the refrigerated container, and the second parameter information being the container's parameter information. By utilizing the LORA sensor to collect the refrigerated container's parameter information and transmitting it to the ship's control device, the transmission distance is increased, power consumption is reduced, and anti-interference capability is improved compared to related technologies. Further, after obtaining the second parameter information, edge computing processing is performed on it to obtain first parameter information. This edge computing processing includes one or more combinations of data parsing, data filtering, and data filtering. In other words, after obtaining the second parameter information, edge computing processing is used to dynamically filter and compress the second parameter information to obtain the filtered and compressed first parameter information. After receiving the first parameter information, it is transmitted to the shore-based terminal via satellite network at a preset transmission frequency. This frequency reduces satellite communication costs, and the use of satellite network enables long-distance data transmission. After transmission, the shore-based terminal provides feedback on adjustments, including changes to the preset transmission frequency and parameters of the refrigerated container. Finally, the transmission frequency and container parameters are adjusted accordingly, enabling remote real-time monitoring and early warning of the refrigerated container.

[0061] In some embodiments, the second parameter information may optionally include one or more combinations of the following: environmental parameters of the refrigerated container, equipment status of the refrigerated container, and positioning data of the refrigerated container.

[0062] In this embodiment, the second parameter information can be one or more combinations of environmental parameters of the refrigerated container, equipment status of the refrigerated container, and positioning data of the refrigerated container. Specifically, the environmental parameters of the refrigerated container can be temperature, humidity, and ventilation volume, etc.; the equipment status of the refrigerated container can be compressor voltage, refrigerant pressure, and equipment alarms, etc.; and the positioning data of the refrigerated container can be GPS (Global Positioning System) coordinates or BeiDou coordinates. By receiving information such as environmental parameters, equipment status, and positioning data of the refrigerated container collected by the LORA sensor, comprehensive monitoring of the refrigerated container is ensured.

By using LORA sensors to collect the parameter information of the refrigerated container and transmitting this information to the ship's control device, the transmission distance is increased, power consumption is reduced, and anti-interference capability is improved compared to related technologies. Meanwhile, this invention receives the first parameter information via a satellite network, ensuring uninterrupted data transmission and enabling long-distance transmission. Furthermore, since the first parameter information is processed by edge computing and transmitted by the control device at a preset transmission frequency, dynamic filtering and compression of the data are achieved, reducing satellite communication costs and improving data quality.

[0069] In some embodiments, optionally, the matching module 404 is specifically used to determine that when the difference between the first parameter information and the preset parameter information is not within a preset range and the first parameter information is greater than the preset parameter information, the adjustment information is to increase the preset information sending frequency and decrease the parameters of the refrigerated container; when the difference between the first parameter information and the preset parameter information is not within a preset range and the first parameter information is less than the preset parameter information, the adjustment information is to increase the preset information sending frequency and increase the parameters of the refrigerated container.

[0070] In this embodiment, the matching module 404 is specifically used to adjust the refrigerated container's parameters as follows: When the difference between the first parameter information and the preset parameter information is not within a preset range, and the first parameter information is greater than the preset parameter information, it indicates that the refrigerated container has malfunctioned. Therefore, the adjustment information is to adjust the preset information transmission frequency to the maximum transmission frequency and decrease the parameters of the refrigerated container, so that the control device, upon receiving the adjustment information, can adjust the preset information transmission frequency to the maximum transmission frequency and control the refrigerated container's parameters to decrease. When the difference between the first parameter information and the preset parameter information is not within a preset range, and the first parameter information is less than the preset parameter information, it indicates that the refrigerated container has malfunctioned. Therefore, the adjustment information is to adjust the preset information transmission frequency to the maximum transmission frequency and increase the parameters of the refrigerated container, so that the control device, upon receiving the adjustment information, can adjust the preset information transmission frequency to the maximum transmission frequency and control the refrigerated container's parameters to increase. When the difference between the first parameter information and the preset parameter information is within a preset range, the adjustment information is to keep the refrigerated container's parameters unchanged and maintain the preset information transmission frequency or adjust the preset information transmission frequency to the minimum transmission frequency. The maximum message transmission frequency can be one packet per minute, and the minimum message transmission frequency can be one packet per hour. By determining adjustment information based on matching results and anomaly warning rules, remote control of refrigerated container parameters is achieved, reducing the occurrence of cargo damage.

[0071] In some embodiments, the remote monitoring device 40 for refrigerated containers may optionally include a display module for displaying first parameter information.

[0072] In this embodiment, the remote monitoring device 40 for the refrigerated container further includes a display module. After the shore-based terminal receives the first parameter information, the display module displays the first parameter information, allowing the owner of the cargo inside the refrigerated container and / or the company owning the vessel to visually view the parameters of the refrigerated container from the shore. Furthermore, when displaying the first parameter information, a change curve of the first parameter information can be generated by combining historical first parameter information, and the change curve can be displayed. This allows the shore-based terminal to predict future first parameter information based on the change curve, thereby sending adjustment information to the control device in advance and reducing the occurrence of cargo damage.

[0074] The first acquisition module 502 is used to acquire the second parameter information collected by the long-distance radio sensor, wherein the second parameter information is the parameter information of the refrigerated container;

[0075] The second processing module 504 is used to perform edge computing processing on the second parameter information to obtain the first parameter information. The edge computing processing includes one or more combinations of data parsing, data filtering, and data filtering.

[0076] The second transmitting module 506 is used to transmit the first parameter information to the shore-based terminal via a satellite network according to a preset information transmission frequency.

[0077] The second receiving module 508 is used to receive adjustment information fed back by the shore-based terminal, wherein the adjustment information corresponds to the first parameter information;

[0078] The third processing module 510 is used to adjust the parameters of the refrigerated container and the preset information transmission frequency according to the adjustment information.

[0079] The remote monitoring device 50 for refrigerated containers provided by this invention is mainly used in the control system of a ship. The ship's control system is installed on the ship. Specifically, the remote monitoring device 50 includes: a first acquisition module 502, a second processing module 504, a second transmission module 506, a second receiving module 508, and a third processing module 510. The first acquisition module 502 can acquire second parameter information collected by a LORA (Long Range Radio) sensor. The LORA sensor is located inside the refrigerated container, and the second parameter information is the parameter information of the refrigerated container. By using the LORA sensor to collect the parameter information of the refrigerated container and transmitting this parameter information to the ship's control system, the transmission distance is increased, power consumption is reduced, and anti-interference capability is improved compared to related technologies. Furthermore, after obtaining the second parameter information, the second processing module 504 can perform edge computing processing on the second parameter information to obtain the first parameter information. The edge computing processing includes one or more combinations of data parsing, data filtering, and data screening. That is, after obtaining the second parameter information, the edge computing processing method is used to dynamically filter and compress the second parameter information to obtain the filtered and compressed first parameter information. After obtaining the first parameter information, the second sending module 506 can transmit the first parameter information to the shore-based terminal via a satellite network according to a preset information transmission frequency. By transmitting the first parameter information according to the preset information transmission frequency, satellite communication costs are reduced, and long-distance data transmission is achieved by utilizing the satellite network for data transmission. After transmitting the first parameter information to the shore-based terminal, the second receiving module 508 can receive adjustment information from the shore-based terminal regarding the first parameter information. This adjustment information includes adjustments to the preset information transmission frequency and the parameters of the refrigerated container. Finally, the third processing module 510 can adjust the preset information transmission frequency and the parameters of the refrigerated container according to the adjustment information. This achieves remote real-time monitoring and early warning of the refrigerated container.

[0080] In some embodiments, the second parameter information may optionally include one or more combinations of the following: environmental parameters of the refrigerated container, equipment status of the refrigerated container, and positioning data of the refrigerated container.

[0081] In this embodiment, the second parameter information can be one or more combinations of environmental parameters of the refrigerated container, equipment status of the refrigerated container, and positioning data of the refrigerated container. Specifically, the environmental parameters of the refrigerated container can be temperature, humidity, and ventilation volume, etc.; the equipment status of the refrigerated container can be compressor voltage, refrigerant pressure, and equipment alarms, etc.; and the positioning data of the refrigerated container can be GPS (Global Positioning System) coordinates or BeiDou coordinates. By receiving information such as environmental parameters, equipment status, and positioning data of the refrigerated container collected by the LORA sensor, comprehensive monitoring of the refrigerated container is ensured.

[0082] One embodiment of the present invention provides a remote monitoring system for refrigerated containers, comprising: the aforementioned remote monitoring device for refrigerated containers used in shore-based terminals; and the aforementioned remote monitoring device for refrigerated containers used in ship control devices.

[0083] The remote monitoring system for refrigerated containers of the present invention mainly includes: the remote monitoring device for refrigerated containers used for shore-based terminals and the remote monitoring device for refrigerated containers used for ship control devices, which can achieve the technical effects of any of the above technical solutions, and will not be elaborated here.

[0084] For example, Figure 6This diagram illustrates a schematic block diagram of a remote monitoring system for refrigerated containers according to an embodiment of the present invention. The remote monitoring system for refrigerated containers provided by the present invention is mainly used for monitoring refrigerated containers, which are specifically designed for transporting goods requiring temperature control during sea transport. Through its built-in refrigeration system, it ensures that goods maintain a constant low temperature or a specific temperature range during transportation. It is widely used for transporting temperature-sensitive goods such as fruits, vegetables, food, pharmaceuticals, and chemicals. Its freight costs are far higher than ordinary containers, therefore, the monitoring during transportation is more stringent. The remote monitoring system for refrigerated containers provided by the present invention mainly includes: a ship-side data acquisition module, a ship-side data processing module, and a shore-based early warning monitoring module. The ship-side data acquisition module mainly includes: environmental sensors, equipment status sensors, and spatial position sensors, thereby collecting environmental parameters, equipment status, and positioning data of the refrigerated container. Environmental parameters include: temperature, humidity, and ventilation volume, etc. Equipment status includes: compressor voltage, refrigerant pressure, and equipment operating alarms, etc. After obtaining data from the refrigerated containers, the IoT data collected by the sensors is transmitted to the microcontroller (control device) in the ship's bridge via the LoRa module. If the transmission distance is too long or the transmission is obstructed by the ship's hull and adjacent stacked containers, a signal relay method can be used to transmit the IoT data to the microcontroller. Upon receiving the data from the refrigerated containers, the microcontroller in the ship's data processing module performs edge computing processing, including parsing, filtering, and frequency control. The microcontroller then sends the processed data to the LoRa gateway or network base station. A reception confirmation mechanism can be set during transmission to ensure successful data delivery. The LoRa gateway then transmits the collected data via satellite network to the cloud platform in the shore-based early warning and monitoring module. Finally, the cloud platform transmits the data to the shore-based monitoring center (shore-based terminal) via 4G / Ethernet. The data is displayed and processed at the shore-based terminal. Specifically, the shore-based terminal displays the data and compares it with standard environmental parameters required for the storage and transportation of refrigerated goods, sets safety thresholds, establishes anomaly warning rules, and promptly feeds back to the ship for appropriate handling. This achieves a closed-loop mechanism for remote monitoring and processing of valuable refrigerated goods, reducing the occurrence of cargo damage. This invention applies local LoRa IoT, edge computing, and satellite communication to refrigerated container monitoring, and uses dynamic data filtering and compression algorithms to reduce satellite communication costs and improve data quality.
