Description

[0001] This application is a divisional application. The application number of the original application is 202010162396.5, and the original application date is March 10, 2020. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present invention relates to the field of industrial control, especially to the sub-fields of transportation and energy-saving control, and is particularly suitable for the design of new ships and the renovation of old ships for the automation and intelligent system of ventilation energy saving in cargo holds of ships. By analogy, the invention can also be used for the ventilation energy saving design of cabins and field shelter hospitals. Background Art

[0003] In the existing cargo hold ventilation design of ships, firstly, the design is mainly based on the installation of electric fans in the cargo hold to discharge the air volume generated by the cooling fans of the refrigerated containers in the cargo hold to the outside of the cargo hold in equal amounts. Moreover, based on conservative safety considerations, the design of cargo hold ventilation capacity is based on the sum of the maximum air volumes generated by the cooling fans of all refrigerated containers that can be stored in the cargo hold when working simultaneously, that is, Q = Σq imax , i is the number of the refrigerated container q in the cargo hold, and max is the maximum air output of the cooling fan. Secondly, the control of the cargo hold fan adopts a single switch control, which cannot be controlled in a branch way according to the specific operation conditions of the refrigerated containers in the cargo hold. Thirdly, as long as the ship is in operation or as long as there are refrigerated containers in the cargo hold, the cargo hold fan must be started. Fourthly, for other stored goods, the cargo hold fan is also started according to the above conditions.

[0004] It can be seen that there is a great waste of energy in this way. The present invention application attempts to optimize the design and solve the energy-saving problem in the current cargo hold ventilation design.

[0005] Therefore, the deficiencies of the prior art are quite obvious, which are specifically manifested in at least the following aspects:

[0006] 1. Cargo hold ventilation is calculated based on the cooling fans of the refrigerated containers stored in the cargo hold working at the maximum air output at the same time, and they work continuously in a switch mode, and specific energy-saving control cannot be implemented according to the cargo situation.

[0007] 2. The control of the cargo hold fan adopts a single switch control, which cannot be divided into different circuits according to the specific operating conditions of the refrigerated containers in the cargo hold.

[0008] 3. The cargo hold fans must be operated as long as the ship is in operation or as long as there are refrigerated containers in the cargo hold.

[0009] 4. For other stored goods, the cargo hold fans are also started according to the above conditions.

[0010] The purpose of the present invention is to provide a method and system for energy-saving cargo hold ventilation to address the deficiencies of the prior art.

[0153] Figure 2 It is a schematic diagram of the container and fan structure, which shows the position correspondence between the cargo hold fan and the container of the container ship. The containers are stacked according to the position coordinates, and the position coordinates are usually numbered on the ship according to rows, columns, and layers. For active containers, usually refrigerated containers, each refrigerated container has a cooling fan at the head of the box. Near the cooling fan, there is usually an air outlet of the ventilation duct, and the ventilation duct is connected to the fan. The fan can specifically include a supply fan and an exhaust fan. For the supply fan, this air outlet is the air outlet, and for the exhaust fan, this air outlet is the air inlet. When the refrigeration machine of the refrigerated container is doing refrigeration work, the cooling fan is started at the same time to exhaust and dissipate the heat from the cooling pipe of the refrigeration machine. At this time, the air outlet or the air inlet is ventilated, or the outlet blows away the hot air generated by the cooling fan, or the inlet draws away the hot air generated by the cooling fan.

[0154] In the design of the cargo hold, one or more blowers, one or more exhaust fans and matching ventilation ducts are usually provided. The blower delivers the air outside the cargo hold into the cargo hold through the ventilation duct. The exhaust fan exhausts the air inside the cargo hold out of the cargo hold. In different designs, there are different design options for whether the exhaust fan is connected to the ventilation duct. In the scheme without ventilation ducts, some exhaust fans are directly installed on the top of the cargo hold and do not need to be connected to the ventilation duct. In the design with ventilation ducts, the exhaust fan extracts the air in the cargo hold through the ventilation duct. In addition, whether it is a ventilation duct for a blower or an exhaust fan, most designs have vents on the ventilation duct, and even the vents are equipped with controllable dampers. Basically, the design layout of these vents is facing the cooling fan of the refrigerated container to better exhaust the hot air from the cooling fan.

[0155] Figure 3 3 is a schematic diagram of the system of the present invention in this embodiment. In the dotted box in 3, numbers 3010, 3020, and 3030 are three different environmental data collection and fan control modes. The specific description is as follows:

[0156] Figure 3 As shown in the number 3010, the collection and control mode supports the P1030 step, the P1040 step, and the P1050 step. Figure 3 As shown in the reference numeral 3011, the micro base station and the sensor communicate in Bluetooth LE communication mode, and as shown in the reference numeral 3012, the fan control subsystem and the fan use the start-stop mode for control.

[0157] Figure 3 The number 3020 in the figure supports the acquisition and control mode of steps P1010 and P1020 using external communication equipment. The external communication equipment and the micro base station are connected through Figure 3 The Bluetooth LE communication is shown as number 3021. The control of the fan control subsystem and the fan in variable frequency speed regulation mode is shown as number 3022.

[0158] Figure 3 The number 3030 indicates the acquisition and control mode using the built-in communication circuit that supports steps P1010 and P1020. The micro base station and the built-in communication circuit communicate using the power carrier mode as shown in number 3031, or the data center subsystem directly acquires data from the built-in communication circuit through the power carrier mode. The fan control subsystem and the fan are controlled using the start-stop mode or variable frequency speed regulation mode as shown in number 3032.

[0159] Figure 3 The data center subsystem in the embodiment communicates with the micro base station through a twisted pair cable as shown in number 3044, and provides POE power to the micro base station. The data center subsystem also communicates with the micro base station, the workstation as shown in number 3060, and the PDA as shown in number 3070 through WIFI as shown in 3042 and BluetoothLE as shown in 3043. In addition, the AC power supply cable as shown in number 3045 is used to realize power carrier communication by the modem and the built-in communication circuit to collect environmental data. In addition, the data center subsystem can also communicate with the cloud center as shown in number 3050 through satellite communication as shown in number 3041 to further realize remote services.

[0160] The P1000 step specifically includes:

[0161] Step P1010: For active containers in the cargo category, collecting the environmental data includes collecting air outlet data of cooling fans of at least one active container, specifically including:

[0162] Step P1011: When the active container is cooling or heating, the cooling fan is calculated according to a fixed exhaust volume.

[0163] Here, the active container mainly includes a refrigerated container driven by a fixed-frequency and fixed-speed motor. Its refrigeration machine works in a switch-type manner, unlike a variable-frequency speed-regulating motor-driven refrigeration machine that can be adjusted according to analog quantities. The cooling fan of its refrigeration machine's external unit is also driven by a fixed-frequency and fixed-speed motor. Therefore, as long as the refrigeration machine is working, its cooling fan will work at a fixed exhaust volume. For example, for a certain brand of 20-foot standard refrigerated container, the power of the refrigeration machine is 11KW, and the exhaust volume of its cooling fan is 4500m 3 / h, therefore, we can calculate the exhaust volume synchronously by collecting the start and stop signals of the refrigerator.

[0164] Step P1012: When the active container is cooling or heating, the exhaust volume of the cooling fan is calculated according to the exhaust function.

[0165] Here, the active container mainly includes a refrigerated container driven by a variable frequency motor, whose refrigeration machine works according to analog quantity adjustment, and correspondingly, the heat dissipation fan of some advanced refrigerated containers is also variable frequency controlled. At this time, we can calculate the exhaust volume by collecting the power of the refrigeration machine according to the exhaust function provided by the refrigerated container manufacturer.

[0166] Step P1013: When the active container is cooling or heating, the exhaust volume of the cooling fan is calculated based on the exhaust volume provided by the internal control circuit of the active container.

[0167] Here, there are some processor systems in the internal control circuits of refrigerated containers, which provide specific exhaust volume data of the cooling fans through refrigerated container communication data. We only need to collect and analyze it to know the specific exhaust volume data.

[0168] In fact, due to the wide variety of brands and models of refrigerated containers, as technology develops, the data provided by their internal control circuits is increasing. This embodiment only provides an idea for collecting data. Specifically, engineers in the industry should be able to find more methods based on this idea, which will not be listed here one by one.

[0169] The air outlet data includes the position coordinates of the active container and the start, stop, rotation speed, exhaust volume, and exhaust speed of the cooling fan included in the active container.

[0170] Step P1020: For the active container, collecting the environmental data includes collecting temperature field data of the active container at least one way and the external air temperature of the cargo hold, and the temperature field data includes the position coordinates of the active container and the air temperature at the position coordinates.

[0171] As mentioned above, the vents of the ventilation ducts are basically facing the cooling fans of a refrigerated container, and the spatial coordinates of the cooling fans are taken from the position coordinates of the container. As an approximate calculation, the position coordinates of the vents also refer to the position coordinates of the nearby cooling fans. Based on this, the temperature field coordinates in three-dimensional space are formed, and the data is still the temperature field data.

[0172] Since the air is flowing, the vents and cooling fans are not sealed but open, and the connection between the cooling fans and vents needs to be calculated according to the aerodynamic equations. In addition, the containers in the cargo hold are not always full. For example, a cargo hold with a depth of 5 standard containers may only have 3 layers of containers. There are no cooling fans in the position coordinates of the top two layers. Therefore, whether it is for air supply or exhaust, for the calculation of temperature field data and the calculation of the influence between each other, engineers in the industry need to consider in detail and use multivariate aerodynamic equations for calculation.

[0173] Step P1030: For the active container, collecting the environmental data includes collecting power consumption data of more than one active container, and the power consumption data includes the voltage, current, power, time of the power consumption of the active container, and the location coordinates of the active container.

[0174] This step is different from the selection steps of P1010 and P1020. It infers the wind data or temperature field data through the active container power supply. The principle is that if an active container is turned on, its power consumption data will be reflected accordingly. Based on this, its position coordinates and wind data or temperature field data can be inferred through the socket of the container. The reason why its position coordinates can be calculated is that in actual work, each active container has a fixed corresponding power socket. In the initial database of the system software, the corresponding relationship between this socket and the container position coordinates needs to be recorded.

[0175] Step P1040: For the passive containers and non-container cargoes among the cargo types, collecting the environmental data includes collecting airflow data of the passive containers and the non-container cargoes for more than one time, and the airflow data includes breathing data and gas composition of the passive containers and the non-container cargoes, and the position coordinates of the passive containers and the non-container cargoes.

[0176] The passive container includes an ordinary container, and the non-container cargo includes bulk cargo. In some cases, these cargoes also need ventilation or even heat dissipation, and this step is designed for these cargoes. The fan control is specifically performed with reference to the specific ventilation and heat dissipation requirements of the cargoes.

[0177] Step P1050: For the passive container and the non-container cargo, collecting the environmental data includes collecting heat data of the passive container and the non-container cargo at least one time, the heat data includes the heat generation of the passive container and the non-container cargo, and the position coordinates of the passive container and the non-container cargo; the position coordinates include row number, column number and layer number.

[0178] Step P1060: Collecting the environmental data also includes user-defined data obtained from computer input devices and supply databases.

[0179] This step refers to the step that does not require the collection of data from the collection equipment in the cargo hold, but only requires the user to input data from the computer input devices such as the keyboard, mouse, scanner, etc. of the system computer, or from the cargo source database. Its characteristic is that the step of collecting data from the cargo hold is omitted, and these collection devices can also be omitted, thereby reducing the complexity and cost of the system.

[0180] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0181] The cargo hold ventilation includes steps P6000 and P7000, specifically including:

[0182] Step P6000: The cargo hold is ventilated by one or more fans and ventilation pipes for connecting the interior and exterior of the cargo hold, specifically including:

[0183] Step P6010: The fan includes one or more blowers that deliver air from the outside of the cargo hold through the ventilation duct into the cargo hold, the blower is connected to the ventilation duct, the ventilation duct includes one or more blower inlets located outside the cargo hold and one or more blower outlets located inside the cargo hold, the blower outlet includes position coordinates, the blower includes switch control, speed control, power consumption, air volume and wind speed, and the blower outlet includes a control valve.

[0184] Step P6020: The fan includes one or more exhaust fans that deliver air from the inside of the cargo hold through the ventilation duct to the outside of the cargo hold, the exhaust fan is connected to the ventilation duct, the ventilation duct includes one or more exhaust fan air inlets arranged inside the cargo hold and one or more exhaust fan air outlets arranged outside the cargo hold, the exhaust fan air inlet includes position coordinates, the exhaust fan includes switch control, speed control, power consumption, air volume and wind speed, and the exhaust fan air inlet includes a control valve.

[0185] Here, the vents are divided into air inlets and air outlets. It should be noted that the present invention application takes into account that in some design options, only a supply fan or only an exhaust fan may be used in the cargo hold, or both a supply fan and an exhaust fan may be used, wherein the number of supply fans and exhaust fans may also be different.

[0186] Step P6030: The fan includes one or more blowers that deliver component air from the component air generator included in the cargo hold into the cargo hold through the ventilation duct, the blower is connected to the ventilation duct, the ventilation duct includes one or more blower inlets located outside the cargo hold and one or more blower outlets located inside the cargo hold, the blower outlets include position coordinates, and the blower includes switch control, speed control, power consumption, air volume and wind speed.

[0187] Here, the present invention application takes into account that certain special goods have special requirements for air composition, such as carbon dioxide concentration, oxygen concentration, formaldehyde concentration, etc. In actual design, it is necessary to introduce an air composition generator or filter based on the specific requirements of the transportation and storage of such special goods.

[0188] Step P6040: The steps P1010 and P1020 further include: collecting the air outlet data and the temperature field data by communicating with the inside of the active container.

[0189] As mentioned before, this is accomplished by collecting signals from inside the container.

[0190] Step P6050: The internal communication specifically includes: using an external communication device to complete the communication by connecting to the external interface of the active container, or using a built-in communication circuit to access the internal control circuit of the active container, using a power carrier to complete the communication by means of modulation and demodulation, collecting the wind data by sensors arranged outside the active container, and collecting the temperature field data by sensors arranged outside the active container. The internal communication includes one channel and multiple channels.

[0191] The present invention application considers that the method for data collection of active containers can be completed by external communication equipment or built-in communication circuits. Depending on the brand and model of containers, the antenna protocol and data format are different. When using the built-in communication circuit, through power carrier communication, the built-in communication circuit can not only communicate with the micro base station and send data to the micro base station, but also communicate with the data center subsystem and send data directly to the data center subsystem.

[0192] P7000 steps: remote maintenance and adjustment of the cloud center, database, and work steps, including:

[0193] Step P7010: The adjusted versions of the contents including the P1000 step, the P2000 step, the P3000 step, the P4000 step, the P6000 step, the P7000 step and the P5000 step are stored in the cloud center, and the P1000 step, the P2000 step, the P3000 step, the P4000 step, the P6000 step, the P7000 step and the P5000 step are adjusted through the remote network.

[0194] Step P7020: store all data generated by the P1000 step, the P2000 step, the P3000 step, the P4000 step, the P6000 step, the P7000 step, and the P5000 step in the database, copy all the data to the cloud center via the remote network, and copy all the data stored in the cloud center to the database.

[0195] The present invention application takes into account the establishment of a remote adjustment function for all software in the system. In this embodiment, since the ship is operating on the sea, the design allows the ship to communicate with the cloud center through satellite communication to implement remote adjustment and remote maintenance.

[0196] P7030 step: Steps for adjusting the cloud center.

[0197] The adjustments to the cloud center are usually adjustments to the software and system by the developer of the system, which are made by the developer based on its own development and the customization requirements of the customer. It is emphasized here that the customization requirements made by the developer based on different customers include individual adjustments to the cloud center, as well as unified adjustments for all customers. The adjustments include software upgrades and modifications to local work steps.

[0198] Step P7040: Includes establishing wireless network coverage in the designated work area.

[0199] The present invention application considers that, in order to facilitate work, wireless network coverage including WIFI, Bluetooth, etc. is established in the work area designated by the user to facilitate the use of wireless terminal devices.

[0200] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0201] The most core measure of the energy-saving method proposed in the present application is to reduce the work of the fan as much as possible according to the needs of the goods, that is, to reduce the ventilation volume of the fan as much as possible.

[0202] The P2000 step specifically includes:

[0203] Step P2010: Based on the position coordinates, associate the cargo in the cargo hold with one or more air outlets of the supply fans and one or more air inlets of the exhaust fans, so that the air delivered by the air outlets of the supply fans and the air extracted by the air inlets of the exhaust fans can influence the air outlet data, the temperature field data, the power consumption data, the airflow data or the heat generation data of the cargo in the cargo hold.

[0204] The main principle proposed in the present invention application is to make the air outlet or air inlet balance the air outlet, temperature field, power consumption, airflow or heat generation of the closest goods, including the following details:

[0205] P2020 Steps:

[0206] QB=QA+ΔOTQ (1)

[0207] In the formula: QA is the exhaust volume; QB is the air volume; ΔOTQ is a set air volume difference;

[0208] VB=VA+ΔOTV (2)

[0209] In the formula: VA is the exhaust air velocity; VB is the wind speed; ΔOTV is a set wind speed difference;

[0210] Based on the air outlet data, calculate QA or VA of one or more cooling fans associated with one or more air supply fan outlets and one or more air exhaust fan inlets, so that QB or VB of one or more air supply fan outlets and one or more air exhaust fan inlets conform to formula (1) or formula (2), and make ΔOTQ or ΔOTV minimized.

[0211] For some designs based on exhaust volume, the air outlet or air inlet and the cooling fan of the active container may not necessarily correspond exactly in terms of position coordinates, and there may be some deviations. In addition, each air outlet or air inlet may correspond to several cooling fans. Therefore, the intention of this step is to use aerodynamic equations according to these correspondences and take these exhaust volumes into account as function variables to increase the accuracy of air regulation.

[0212] P2030 Steps:

[0213] TA=TA0+ΔOTT (3)

[0214] Where: TA0 is the lowest temperature inside the cargo hold; TA is the air temperature at the temperature field; ΔOTT is a set temperature difference;

[0215] Based on the temperature field data, and under the premise that the air temperature outside the cargo hold is greater than TA0 of the cargo hold, calculate the TA in the temperature field data associated with one or more air outlets of the supply fan and one or more air inlets of the exhaust fan, and through the P6000 step, make it conform to formula (3) and make ΔOTT minimize.

[0216] For some designs based on temperature fields, the air outlets or air inlets and the cooling fans of active containers may not necessarily correspond exactly in terms of position coordinates, and there may be deviations. In addition, each air outlet or air inlet may correspond to several cooling fans. Therefore, the intention of this step is to use thermodynamic equations based on these correspondences and take these temperature field data into account as function variables to increase the accuracy of air temperature regulation.

[0217] P2040 Steps:

[0218] According to the power consumption data, the power consumption data of one or more active containers associated with one or more air supply fan outlets and one or more air exhaust fan inlets are calculated, and the QA or VA or temperature field data of one or more cooling fans of one or more active containers are deduced, so that formula (1) or formula (2) or formula (3) is established, and ΔOTQ is minimized, ΔOTV is minimized, or ΔOTT is minimized.

[0219] The intention of this application of the present invention is to design another control method based on active container power consumption data. As mentioned above, this method collects the power consumption data of the socket on each container power socket as the basis for the air volume at the air outlet or air inlet, so as to avoid collecting data for each active container. The characteristic of this solution is that it eliminates the need for external communication equipment or built-in communication circuits for container collection, which is more suitable for the reconstruction of old ships.

[0220] P2050 Steps:

[0221] SBD=BD+ΔBD (4)

[0222] Where: BD is the breathing data; SBD is the air supply volume; ΔBD is the breathing difference;

[0223] SIGD=IGD+ΔIGD (5)

[0224] Where: IGD is the gas composition; SIGD is the input gas composition; ΔIGD is the gas composition difference;

[0225] According to the airflow data, the BD and IGD of the one or more passive containers and the non-container cargo associated with the air outlet of the one or more blowers are calculated, and the P6030 step is performed so that the SBD and SIGD of the blower meet equations (5) and (6), and ΔBD and ΔIGD are minimized.

[0226] P2060 Steps:

[0227] SCR+CR=ΔCR (6)

[0228] In the formula: CR is the calorific value; SCR is the heat dissipation; ΔCR is the heat difference;

[0229] According to the heating data, the CR of the one or more passive containers and the non-container cargo associated with the one or more air outlets of the supply fan and the one or more air inlets of the exhaust fan is calculated, so that the SCR generated by the one or more air outlets of the supply fan and the one or more air inlets of the exhaust fan conforms to formula (6) and the ΔCR is minimized.

[0230] P2050 and P2060 are methods of controlling fans for passive containers and non-containers (such as bulk cargo) in the present invention.

[0231] P2070 Steps:

[0232] Based on all the cargo stored in the entire cargo hold and all the air outlets of the blowers and all the air inlets of the exhaust fans, and according to the specific execution of steps P2010, P2020, P2030, P2040, P2050 and P2060, the calculation results are overall correlated and the aerodynamic equations are optimized to obtain the minimum ventilation requirement for the entire warehouse.

[0233] P2080 Steps:

[0234] Based on the set number of people, the minimum ventilation volume required for the breathing survival of the set number of people is added to the ΔOTQ, ΔOTV, ΔOTT, ΔBD, ΔIGD, and ΔCR.

[0235] This is the design of the present invention application for the breathing safety of personnel in the cargo hold, which is intended to provide the breathing requirements of a set number of people so that the fan can provide the basic breathing needs of personnel in the cargo hold.

[0236] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0237] The P3000 step specifically includes:

[0238] Step P3010: The control function includes executing the control of starting, stopping, speed regulation, wind speed regulation, and air volume regulation for more than one of the fans, and also includes the gate control of the blower outlet control gate and the exhaust fan inlet control gate, and also includes the control of all fans in the entire cargo hold.

[0239] As mentioned above, there are three specific methods for controlling the fan: first, for a fixed-frequency fan, the control function is to start and stop the fan. Second, for a variable-frequency speed-regulating fan, the control function is to perform analog variable-frequency control. For fans with gates at the air outlet and the air inlet of the exhaust fan, the gate control is performed based on the air outlet data or temperature field data at the position coordinates.

[0240] Step P3020: adopt the real-time open-loop control method, execute the above-mentioned step P1000 once and step P2000 once according to the set open-loop time interval, and calculate the control function. The open-loop time interval is greater than 20 minutes.

[0241] The real-time open-loop control method applied in the present invention refers to the open-loop control method between acquisition and control according to the control theory, that is, based on the acquired data, a control function is generated to directly control the fan or the fan and the gate. However, it should be noted that the so-called open loop here is only for the process time from acquisition to control, and this time difference is relatively long, for example, greater than 20 minutes. It should be noted that the 20 minutes here is just an example, and this number can be longer or shorter depending on the size of the cabin. From the perspective of the actual structure of the acquisition and control links, it is still a closed loop on a large time scale.

[0242] Step P3030: adopt the real-time closed-loop control method, execute the P1000 step more than once according to the set closed-loop time interval, use the environmental data as a closed-loop feedback parameter to modify the ΔOTQ or the ΔOTT or the ΔIGD or the ΔCR, and then execute the P2000 step to calculate the control function, and the closed-loop time interval is less than 20 minutes.

[0243] The present invention applies the real-time closed-loop control method here, such as Figure 4As shown. As shown in number 4010, there is a cargo hold, in which refrigerated containers (refrigerated containers) are stacked. In the refrigerated container, the refrigerator has a closed-loop temperature control system, for example, a temperature control system using a PID regulator. In this temperature control system, signals including internal set temperature, supply air temperature, return air temperature, external ambient temperature, etc. of the refrigerated container are obtained from the external interface of the refrigerated container through an external communication device, or these signals are obtained through a built-in communication circuit. These signals are output as shown in number 4036, and are input to the input of the system as a negative feedback signal as shown in number 4032. Together with the system given signal as shown in number 4031 and the AI ​​given signal as shown in number 4033, a complete feedback signal as shown in number 4043 is formed, which drives the fan control subsystem as shown in number 4020 to control the fan, and finally forms a closed-loop control method in control theory as shown in number 4035. In other words, based on the collected data, the control function is generated as closed-loop negative feedback data to directly control the fan or the fan and the gate. However, it should be noted that the so-called closed loop here refers to the process time from acquisition to control, and this time difference is relatively short, for example, less than 20 minutes. It should be noted that the 20 minutes here is just an example, and this number can be longer or shorter depending on the size of the cabin.

[0244] Step P3040: Adopting the artificial intelligence control method, when executing the step P1000, increase the collection of time data to become extended environmental data, and calculate and optimize the control function based on the artificial intelligence algorithm, including setting the environmental data with the position coordinates as an image sequence, learning the extended environmental data, and training empirical parameters.

[0245] The control variable formed by the artificial intelligence control method here is output to Figure 4 The control variable shown as 4033 in .

[0246] The data required for artificial intelligence to learn in this invention application refers to data obtained through processing including but not limited to the following methods. The engineers and technicians in the industry should understand that according to the development of artificial intelligence technology, other beneficial methods can also be incorporated to make the invention application more perfect. They are:

[0247] 1. Form historical data.

[0248] When collecting environmental data, the time parameters of the collection are added to form a data set of historical data.

[0249] 2. Generate data with the earth's longitude, latitude and weather.

[0250] When collecting environmental data, the real-time latitude and longitude data of the ship and local weather parameters are added and incorporated into the database.

[0251] 3. Data visualization.

[0252] When collecting environmental data, the same batch of collected data is compiled into a data frame according to the location coordinates of the data, and is included in the database as a frame in an image or video.

[0253] like Figure 5 As shown, this is an example of the data visualization invention in the present application.

[0254] Numbers 5010 and 5020 are respectively the vertical planes where the heads of the refrigerated containers stacked in a cargo hold on the ship are located. The head of the refrigerated container refers to the end of the refrigerated container where the refrigeration machine operation panel is located. In a ship, the stacking of containers has a three-dimensional coordinate number, namely, the row number Bay, the column number Row, and the layer number Tier, referred to as BRT coordinates. Figure 5 In the figure, the white squares indicated by numbers 5012 and 5022 are the locations of the ballast tanks at the bottom of the ship, and the gray squares indicated by numbers 5011 and 5021 are the heads of the stacked refrigerated containers, wherein the air temperature at the heads changes with the operation of the refrigerated containers. For ease of description, the patent application of the present invention uses C1 to C9 to indicate the data such as the air temperature at the BRT coordinates of the location point where the refrigerated container is located or the exhaust volume and exhaust speed of the cooling fan. It should be noted that the data is a continuous quantity. Figure 5 C1 to C9 are used to indicate the difference of the continuous quantity from small to large, but this does not mean that the continuous quantity is only divided into 9 levels of C1 to C9. The data of one frame refers to the collection of a container in a cargo hold, which is stored in the database of environmental data according to the BRT coordinates. For other active containers, passive containers or non-container goods, the same is true.

[0255] Artificial intelligence algorithms are used for deep learning and labeling, and training is performed using, for example, convolutional neural network (CNN) algorithms, Bayesian algorithms, adversarial neural network (GAN) algorithms, firefly algorithms, and ant colony algorithms. The optimization indicators include strategies such as minimum energy consumption of the fan, minimum equipment action (such as minimum start and stop times, minimum number of fans started and stopped), minimum disturbance to the internal temperature field, and minimum disturbance to the wind output data. The actual control room results are stored in the database according to time, and all relevant data such as ship route data, weather data, container loading and unloading data, and docking terminal data that can be obtained are all entered into the database. These are all used as the category content and experience content of the deep learning of the artificial intelligence algorithm, so that as the system runs, the results of the artificial intelligence algorithm become more and more "intelligent", and at the same time, due to the reduction of equipment actions, the service life of the equipment is also extended.

[0256] Step P3050: Calculate and display the saved electrical energy and fuel consumption compared with the traditional control algorithm.

[0257] The design intention here is to display the energy-saving effect on the terminal interface, such as the real-time and cumulative figures of electricity and fuel consumption, to provide a basis for user management and decision-making, and at the same time increase the friendliness of the user interface.

[0258] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0259] The purpose of the P4000 step in the present application is to specifically control the fan based on the control function calculated and generated by the P3000 step.

[0260] The P4000 step specifically includes:

[0261] Step P4010: Includes the use of manual and automatic conversion, and the implementation of manual-automatic switching.

[0262] Whether it is a new ship design or an old ship renovation, based on the handover between traditional control and modern control, a switch between manual and automatic is designed here to facilitate the user to have an adaptation process. When switching to manual control, all controls are carried out according to the original traditional control method. Of course, this step is not a mandatory option for the application steps of the present invention. In actual design, the designer can choose whether to adopt this step according to the user's intention.

[0263] Step P4020: includes switch output, executing the control function included in the control function to perform start and stop control on the fan.

[0264] This step of applying for the present invention is an option, which is adopted for fans with fixed-frequency motors.

[0265] Step P4030: includes analog output, executing the control function included in the control of the fan including starting, stopping, speed regulation, wind speed regulation, and air volume regulation, to complete the control of the fan.

[0266] This step of the present invention is an option, which is adopted for fans that adopt variable frequency control.

[0267] Step P4040: includes output verification, specifically, verifying the validity of the output terminal by checking the validity of the switch output step, the analog output step, and the manual-automatic conversion step.

[0268] This step of the present invention application is an option, which is selected in order to fully improve the reliability and observability of the system, and its intention is to make an intuitive screen diagram for the control action on the system control interface. However, it should be noted that this diagram is a preliminary diagram of the control process. For example, if a certain temperature field has a high temperature, the fan must be turned on according to the control function, so the start-up status of the fan is displayed on the screen. If the start-up status is not displayed, it means that the actuator has a fault, which can prompt the crew to repair the corresponding actuator. If the startup is successful, if you want to see the actual effect after the fan is started, you still have to wait until the collected data changes, which is the real control success.

[0269] Step P4050: Execute step P4020, step P4030 and step P4040 based on all fans in the entire cargo hold.

[0270] The purpose of this step in the present invention is that when a cargo hold has multiple fans, these fans are uniformly controlled, and their control functions need to establish a multivariate equation group for correlation calculation. The inventor believes that engineers in the industry are capable of designing the specific design of the equation group, and will not be described in detail here.

[0271] Step P4060: Perform step P4050 for all cargo holds and record the results.

[0272] The intention of applying this step in the present invention is to control all cargo holds of the entire ship. In fact, it is computer controlled one by one, and the calculation equations do not need to be correlated with each other. However, one option designed by the inventor here is that if the design of load balancing for the entire cargo holds of the entire ship is to be considered, then this step needs to be included in the overall consideration of load balancing for the entire cargo holds of the entire ship.

[0273] Step P4070: including terminal equipment, communicating with the terminal equipment via wired and wireless means to achieve control and display of the terminal equipment.

[0274] The intention of applying this step of the present invention is to use PDA or smart phone as terminal device, and adopt ship-wide or local WIFI wireless network coverage, so that the crew can monitor the control system at any time through mobile monitoring.

[0275] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0276] The P5000 step specifically includes:

[0277] Step P5010: The chain accounting using the blockchain encryption and decryption specifically includes:

[0278] Step P5011: In the communication link between the environmental data and the database, the blockchain is used for encryption and decryption.

[0279] Step P5012: Use chain accounting when recording the environmental data, the database, and the control function.

[0280] Chained accounting is a basic feature of blockchain technology. It uses incremental database management for operations such as adding, deleting, checking, and modifying data. Each operation generates a record, and the record contains a directional marker pointer. Here, the present invention applies to the collection of environmental data, the generation of control functions, and queries, all of which are included in chained accounting and blockchain encryption and decryption to prevent tampering and denial. The encryption and decryption algorithm is an algorithm that supports blockchain technology, such as encryption and decryption algorithms including DES, 3DES, AES, RC2, RC4, IDEA, RSA, DSA, ECC, BLOWFISH, KPCS, DM5, SHA, SSF33, SSF28, SCB2, SM1~SM9, and other newly developed encryption and decryption algorithms.

[0281] Step P5020: The adoption of consensus and audited communications and access, specifically including:

[0282] Step P5021: For ship operating companies, shipowners, container customers, insurance companies, technical operation and maintenance companies, and authorized customers, a set consensus mechanism is adopted to authorize access, track and incrementally record all their operations.

[0283] Step P5022: Provide operation permissions to the ship operating company, the ship owning company, the container customer, the insurance company, the technical operation and maintenance company, and the authorized customer based on the set authorization.

[0284] Step P5023: Based on the provisions of the service agreement, the container customer is provided with the ability to query and modify the working parameters of the container entrusted for transportation, and reset and record them.

[0285] According to the blockchain principle, consensus is actually established for all users who are allowed to access, and each has its own independent password access system. Among them, according to the insurance contract signed by the cargo owner, shipping company, insurance company, etc., if the cargo owner is allowed to remotely modify the operating data of the container, such as temperature setting, gas setting, etc., the container can be remotely accessed and reset, which is very helpful for improving transportation services1, and is also an important innovation of the present invention application.

[0286] Step P5030: The support for multi-center data storage specifically includes: the multi-centers include the ship data center, the data center designated by the ship operating company, the data center designated by the shipowner company, the data center designated by the container customer, the data center designated by the insurance company, the data center designated by the technical operation and maintenance company, and the data center designated by the authorized customer. The support for multi-center data storage includes copying the data involved to these data centers.

[0287] In actual work, the accessing user can set his own data center on any designated network storage, such as setting it on the server of a provider specializing in data storage services. In addition, regarding the future development of blockchain technology, the intermediate technical personnel in the industry should understand that some functions incorporated into this system are within the scope of protection of the present invention application.

[0288] 2. System Description

[0289] The system of the new ship design scheme for energy-saving cargo hold fans of refrigerated container ships is implemented in this way:

[0290] A blockchain cargo hold ventilation energy-saving system, which is built on a cargo hold platform where ventilation is achieved by a fan and a control box. The energy-saving system includes one or more data acquisition subsystems, one or more fan control subsystems, and a data center subsystem. The data center subsystem is respectively connected to one or more data acquisition subsystems and one or more fan control subsystems and one or more blockchain modules connected to the data acquisition subsystems, one or more fan control subsystems, and the data center subsystem.

[0291] like Figure 3 As shown, this is a system schematic diagram of this embodiment, in which the data acquisition subsystem adopts the acquisition and control mode shown as number 3020 that supports steps P1030, P1040, and P1050. Figure 3 As shown in the reference numeral 3011, the micro base station and the sensor communicate in Bluetooth LE communication mode, and as shown in the reference numeral 3012, the fan control subsystem and the fan use the start-stop mode for control.

[0292] As for other working modes of the data acquisition subsystem, technical personnel in the industry can directly adopt them according to number 3010 and number 3030, which will not be repeated here.

[0293] like Figure 6 As shown, this is a structural diagram of a specific embodiment of a 600-cargo-only refrigerated container ship consisting of 4 cargo holds. The present invention application includes the control of multiple cargo holds, and multiple cargo holds can share one data center subsystem or multiple data center subsystems.

[0294] exist Figure 6 Among them, No. 6010 is the data center subsystem, No. 6020 is the fan control panel, No. 6030 is the workstation, which is connected to the data center subsystem through WIFI, and No. 6040 is the mobile tablet PDA, which is also connected to the data center subsystem through WIFI. Figure 6 It also includes cargo hold 1, cargo hold 2, cargo hold 3, and cargo hold 4. CS1 / 1CHP, CS2 / 2CHP, CS3 / 3CHP, and CS4 / 4CHP are the fan control cabinets of cargo hold 1, cargo hold 2, cargo hold 3, and cargo hold 4 respectively, and MSB1CH, MSB2CH, MSB3CH, and MSB4CH are the fan control subsystems connected to the CS1 / 1CHP, CS2 / 2CHP, CS3 / 3CHP, and CS4 / 4CHP control cabinets respectively.

[0295] Among them, No. 6011 and 6012 are the WIFI and BluetoothLE antennas of the data center subsystem respectively, No. 6013 is the communication cable from the data center subsystem to the fan control panel to directly control the fan control panel, and the fan control panel is connected to No. 6021, 6022, 6023, 6024 to access the CS1 / 1CHP, CS2 / 2CHP, CS3 / 3CHP, CS4 / 4CHP fan control cabinet to achieve control. Or the data center subsystem is connected to MSB1CH, MSB2CH, MSB3CH, MSB4CH through No. 6014, 6015, 6016, 6017 to control the CS1 / 1CHP, CS2 / 2CHP, CS3 / 3CHP, CS4 / 4CHP fan control cabinet to achieve control.

[0296] In this embodiment, both the workstation and the PDA are connected to the data center subsystem via WIFI to implement operations on this system.

[0297] The present invention application also includes the wiring subsystem and the location layout of each subsystem: First, as a wiring subsystem, the inventor provides an option of using Category 6 twisted pair wiring that supports the ITA568 standard, and implementing local WIFI wireless communication network coverage to facilitate the use of mobile terminals. In terms of location layout, the data acquisition subsystem is placed in the cargo hold of the ship, the fan control subsystem is placed in the control box of the cargo hold fan, and the data center can be placed in the ship's cab or in the same machine room as other ship information equipment because of its small size.

[0298] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0299] The data acquisition subsystem includes a micro base station, an external communication device or a built-in communication circuit and a sensor module, which is used to collect environmental data of the cargo hold.

[0300] The micro base station includes a first housing, a first processor, a first power module, a first temperature sensor, a first wired network connection module, a first wireless network connection module and a first power carrier communication module. Under the control of the first processor, the micro base station is connected to the data center subsystem through the first wired network connection module or the first wireless network connection module, and is connected to one or more external communication devices through the first wired network connection module or the first wireless network connection module, and is connected to one or more built-in communication circuits through the first power carrier communication module. The first power module includes a power supply module taken from the cargo hold AC power supply. When the micro base station uses the first wired network connection module to communicate with the data center subsystem, the first power module includes a POE / PD network power supply module, and the first temperature sensor is used to collect the air temperature outside the cargo hold.

[0301] The first wireless network connection module of the micro base station designed in the present invention adopts both WIFI and Bluetooth LE communication modules, wherein WIFI is used to network with mobile terminals, and Bluetooth LE is used to network with external communication devices. It should be noted that although the communication mode between Bluetooth LE and the external communication device here can adopt one-to-one, one-to-many connection mode, and broadcast mode, in order to enhance the reliability of communication, it is best to design a one-to-one connection mode or a broadcast mode. Based on the consideration of waterproofing of ship equipment, the shell of the micro base station is designed to adopt a fully sealed stainless steel shell. The shell is grounded and floating, and is connected to the metal parts of the hull with metal fasteners. The grounding of the external antennas of WIFI and Bluetooth LE is floating and shall not be connected to the shell. The micro base station and the data center are connected by a six-category shielded 8-core 4-pair twisted pair cable with a waterproof connector. The power supply of the micro base station adopts a POE / PD power supply, and the power is taken from the data center subsystem.

[0302] The external communication device includes a second housing, a second processor, a second power module, a second communication interface, a second wired network connection module and a second wireless network connection module, and is placed outside the active container. Under the control of the second processor, the external communication device is connected to the micro base station through the second wired network connection module or the second wireless network connection module, and is connected to the communication interface of the active container through the second communication interface, so as to communicate with the control circuit inside the active container and collect data of the active container; the second power module includes an independent AC power supply module or a battery power supply module or a module that draws power from the communication interface of the active container.

[0303] The present invention application points out that a one-to-one connection mode or a broadcast mode is adopted between the external communication device and the micro base station. When the broadcast mode is adopted, the micro base station performs roll-call active broadcasting according to the ID number of the external communication device, and the external communication device loads the environmental data through the reply broadcast packet. Considering the length of the broadcast packet, the Bluetooth BLE communication protocol above 5.0 is adopted here. The power of the external communication device is directly drawn from the RS232 port of the refrigerated container, that is, the second power module is powered by the RS232 wide port. In the second processor, corresponding refrigerated container data adaptive parsing software is designed for different refrigerated container brands and models.

[0304] The built-in communication circuit includes a third circuit board, a third processor, a third communication interface, a third power carrier communication module and a third shell, and is placed inside the active container. Under the control of the third processor, the built-in communication circuit is connected to the AC power supply cable through the third power carrier communication module, and then communicates with the first power carrier communication module in the micro base station through the AC power supply cable, and transmits the environmental data to the micro base station. Under the control of the third processor, the built-in communication circuit is connected to the AC power supply cable through the third power carrier communication module, and then communicates with the modem included in the data center subsystem through the AC power supply cable, and transmits the environmental data to the data center subsystem. Under the control of the third processor, the built-in communication circuit is connected to the control circuit inside the active container through the third communication interface to communicate and collect the active container data. The built-in communication circuit includes a circuit board card mode without a shell or an independent module mode with a third shell.

[0305] The present invention provides an option that the built-in communication circuit can be designed according to the present invention or can be a ready-made product from other manufacturers that has been built into the refrigerated container. However, this communication based on power carrier is easily interfered by the ship's electrical equipment, so it can be used as a supplement to the present invention.

[0306] The sensor module includes a module connected to the control box for collecting fan power data, and is arranged inside the cargo hold for collecting temperature, wind speed, air volume, and humidity data; the sensor module is connected to the micro base station by connecting to the external communication device, directly connected to the micro base station, and transmits the collected data to the micro base station.

[0307] This is another environmental data collection solution provided by the present invention application, which is a modifier module solution connected to the power socket of the refrigerated container.

[0308] The active container data includes environmental data, and the first power carrier communication module and the third power carrier communication module include modems.

[0309] The data acquisition subsystem also includes a keyboard, a mouse, a computer input device and a storage device for storing a supply source database, and the environmental data is collected from the keyboard, the mouse, the computer input device and the supply source database.

[0310] This step refers to the step that does not require the collection of data from the collection equipment in the cargo hold, but only requires the user to input data from the computer input devices such as the keyboard, mouse, scanner, etc. of the system computer, or from the cargo source database. Its characteristic is that the step of collecting data from the cargo hold is omitted, and these collection devices can also be omitted, thereby reducing the complexity and cost of the system.

[0311] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0312] The fan control subsystem includes a fourth housing, a fourth processor, a fourth power module, a fourth output terminal, and a fourth input terminal.

[0313] The fourth processor controls the fourth output terminal and the fourth input terminal to complete the operation of the fan control subsystem.

[0314] The fourth output end includes a switching output circuit, an analog output circuit and a manual-automatic conversion switch, which are used to control the AC contactor or frequency conversion controller in the control box to achieve start and stop control or speed control of the fan.

[0315] The fourth input end includes a fourth wired network connection module and a fourth wireless network connection module, which are used to connect to the data center subsystem to achieve communication and receive control instructions of the data center subsystem.

[0316] The fourth output terminal also includes an output verification module, which detects the switch output circuit, the analog output circuit and the manual-automatic conversion switch, and sends the detection result to the data center subsystem through the fourth input terminal.

[0317] As a supplement to the above, the fan control subsystem here includes not only the circuit designed by the present invention, but also includes a finished programmable controller completed through programming.

[0318] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0319] The data center subsystem includes a network server, a work step subsystem, storage, a network switch, a POE / PSE network power supply module, and a wireless network communication module.

[0320] The network server runs the working step subsystem to complete the collection of the cargo hold environment data, calculate the control function, output the control instruction, and achieve energy saving by controlling the fan.

[0321] The network switch includes an Ethernet switch, which is used to connect the network applications including the data acquisition subsystem, the fan control subsystem and the system, and the connection methods include optical fiber, twisted pair wired network and wireless network.

[0322] The wireless network communication module includes a short-distance wireless network communication module, a long-distance wireless network communication module and a satellite communication module. The Ethernet module is connected to the network switch, the long-distance wireless network communication module and the satellite communication module are connected to the public network or the satellite network. The short-distance wireless network communication module such as WIFI and BluetoothLE is connected to the data acquisition subsystem and the fan control subsystem to achieve communication. The long-distance wireless network communication module can be selected from GPRS, 3G, 4G, 5G, 6G, 7G, 8G, etc., and the satellite communication module can be selected from GPS, Beidou, Galileo, and GLONASS.

[0323] The data center subsystem also includes wireless network coverage equipment, which is specifically included in the wireless network communication module to facilitate the mobile use of wireless terminals.

[0324] As an option, the antenna of the satellite communication module needs to be installed at a location convenient for satellite communication according to the requirements of the satellite communication product, and connected to the network computer or the interface of the network server through a cable.

[0325] The POE / PSE network power supply module includes a module of a power supply end supporting the POE standard protocol, and supplies power to the POE / PD end including the micro base station that complies with the POE protocol standard through the twisted pair cable of the network switch.

[0326] The storage is used to store data and software, including mechanical hard drives and solid-state drives.

[0327] The data center subsystem includes an integrated structure integrated into one chassis or a split structure of multiple independent chassis.

[0328] The data center subsystem also includes a modem to enable communication with the built-in communication circuit.

[0329] The data center subsystem also includes wired and wireless terminal devices to achieve remote control and display.

[0330] The system includes a cloud center, and the data center subsystem also includes satellite remote communication to achieve remote communication and remote maintenance with the cloud center.

[0331] The wireless terminal is, for example, a PDA, a mobile phone, or a laptop computer. The modem is, for example, a modem based on power line carrier communication. The POE standard includes current and future POE adjustment versions. This embodiment uses a version that supports the IEEE 802.3bt protocol. On a 100-meter Cat 5E cable, it supports a single-port 71-90W load, which is sufficient for the power consumption of the data acquisition subsystem and the fan control subsystem in most cases.

[0332] On the basis of the above technical solutions, in other solutions of the present invention, one or more of the following local improvement measures may be adopted:

[0333] The blockchain module is connected between the data acquisition subsystem and the data center subsystem, and between the data center subsystem and satellite remote communication, and specifically includes at least an encryption and decryption submodule, an access consensus and audit submodule, and a chain accounting submodule.

[0334] The blockchain module is composed of pure hardware circuits, a combination of hardware and software, and is designed by the CPU system and software steps in the data acquisition subsystem. In this embodiment, the data acquisition subsystem and the data center subsystem, the data center subsystem and the wireless communication through the remote network (for example, communication with the cloud center, communication with the ship operating company, communication with the insurance company, and communication with the system service provider) all adopt the blockchain model. Especially for shippers, shipping companies and insurance companies, the multi-center and anti-repudiation in the blockchain have practical value.

[0335] Specific embodiment 2: Energy-saving transformation plan for old refrigerated container ship cargo hold fans

[0336] This embodiment is a solution for reconstructing old ships of the present invention. Compared with the above-mentioned embodiment, the similarities are not repeated here. The difference lies in a combination or all of the following options:

[0337] 1. Use wireless network communication as much as possible to reduce physical line wiring. For example, wireless communication can be used partially or completely between the data center subsystem, the data acquisition subsystem, and the fan control subsystem. Here, the first power module and the fourth power module of the micro base station in the data acquisition subsystem and the fan control subsystem are all taken from the ship's AC power supply.

[0338] 2. The WIFI antenna of the micro base station installed inside the warehouse is led out of the warehouse through a cable to facilitate communication between the micro base station and the data center subsystem.

[0339] 3. Lead the WIFI antenna of the data center subsystem, which is used to communicate with the micro base station and establish wireless network coverage, outdoors and install it in a location that is convenient for communication, such as the location of the ship's superstructure.

[0340] 4. When the built-in communication circuit mode of the refrigerated container is adopted, the reception of power carrier communication can be realized through the data center subsystem in addition to the micro base station. In this case, a modem for realizing power carrier communication needs to be installed on the data center subsystem.

[0341] 5. For the collection of environmental data, the following options are available based on the requirements of the shipowner or shipyard:

[0342] 5.1. The simple sensor module acquisition method, these sensors are installed in the fan control box, collect the socket power data of the refrigerated container or calculate by collecting the incoming power data of the fan control box. This solution has a low cost.

[0343] 5.2. The data center directly collects environmental data of refrigerated containers with built-in communication circuits through power carriers. This solution has the lowest cost, but if some refrigerated containers are not equipped with built-in communication circuits, the environmental data of these refrigerated containers cannot be collected.

[0344] 5.3. The method of collecting environmental data by the location communication module requires that each refrigerated container be equipped with an external communication module, which is more expensive but ensures that the environmental data is collected completely.

[0345] 5.4. The combination of the above three methods is a complete solution of the present invention, which collects the most complete environmental data and has the best control effect.

[0346] Specific embodiment 3: Energy saving solution for bulk carrier cargo hold fans

[0347] As the present invention application, the difference between the fan energy-saving scheme for bulk carriers and container ships lies in the collection of environmental data and the control method of the fan. Accordingly, the specific scheme is similar to the above two schemes and is not repeated. The main difference lies in the combination or all of the following options:

[0348] 1. Environmental data is collected using steps including P1030, P1040, and P1050.

[0349] 2. The environmental data collection module includes a sensor module.

[0350] 3. The steps of fan control include P2050, P2060, P2070 and P2080.

[0351] 4. Other factors will be determined by industry engineers based on the specific characteristics of the bulk carrier.

[0352] Specific embodiment 4: Energy saving solution for land storage fans

[0353] As the present invention application, as land storage, compared with the fan energy saving of the above scheme, the similarities are not repeated here, and the main difference lies in the combination or all of the following options:

[0354] 1. Since the building materials of land-based warehouses are not made of all-steel materials like ships, the internal and external wireless networks of land-based warehouses can communicate, and the cargo holds of ships can communicate.

[0355] 2. Land warehouses can access the Internet and cloud centers without the need for satellite communications like ships. Only ordinary access is required, such as fiber-optic broadband.

[0356] 3. Land warehousing does not need to add geographic coordinate information to the extended environmental data like ships, so the relevant algorithms do not need to consider the movement of geographic coordinates.
