[0028] In order to make those skilled in the art better understand the present application, Figure 1 The refrigerated container power supply system based on railway transportation proposed in this application is briefly explained.

[0029] See also Figure 1, shows a schematic diagram of a refrigerated container power supply system based on railway transportation in one embodiment of the present application.

[0030] like Figure 1 As shown, the refrigerated container power supply system based on railway transportation proposed in the present application can mainly include a refrigerated container, a backpack generator set and a generator set controller, wherein the refrigerated container is arranged on a railway freight train, and the railway freight train can include multiple refrigerated containers. The refrigerated container can be used to transport goods that need to be refrigerated and preserved. The backpack generator set is assembled on the refrigerated container, and specifically can be arranged at the end of the refrigerated container. The backpack generator set can be used to supply power to the corresponding refrigerated container separately. The generator set controller is configured on the backpack generator set, and can be used to control the corresponding backpack generator set to perform power supply actions according to the set control strategy.

[0031] Based on the system proposed in the present application, by respectively installing backpack-type generator sets on multiple refrigerated containers, the backpack-type generator sets corresponding to the multiple refrigerated containers can work independently, and by controlling the backpack-type generator sets through the generator set controller, independent control of different backpack-type generator sets can be achieved, thereby improving the flexibility of power supply to refrigerated containers.

[0032] Next, we will combine Figure 2 The structure of the generator set controller proposed in this application is briefly explained.

[0033] See also Figure 2 , shows a schematic diagram of a generator set controller in one embodiment of the present application.

[0034] like Figure 2 As shown, the generator set controller 210 can mainly include an acceleration data acquisition module 211, a storage module 212, a human-computer interaction module 213, a communication module 214, a control module 215, a power supply module 216, a positioning module 217, a prompt module 218, and an environmental parameter acquisition module 219. The acceleration data acquisition module 211, the storage module 212, the human-computer interaction module 213, the communication module 214, the power supply module 216, the positioning module 217, the prompt module 218, and the environmental parameter acquisition module 219 are all connected to the control module 215.

[0035] The acceleration data acquisition module 211 may be used to acquire acceleration data of the refrigerated container. Specifically, the acceleration data may be the three-axis acceleration of the refrigerated container, which may be used to monitor the posture of the refrigerated container to prevent the refrigerated container from tipping over during transportation.

[0036] The environmental data acquisition module 219 can be used to collect internal environmental parameters of the internal environment of the refrigerated container and external environmental parameters of the external environment. The internal environmental parameters may specifically be the internal temperature of the refrigerated container, and the external environmental parameters may specifically be the ambient temperature outside the refrigerated container, which can serve as a basis for the generator set controller to control the backpack generator set.

[0037] The positioning module 217 can be used to obtain the geographic location information of the refrigerated container. The geographic location information can specifically include the longitude and latitude of the area where the refrigerated container is located, the poster height and weather conditions, which is used to provide a basis for the generator set controller to control the backpack generator set. In a specific embodiment, the positioning module can be a B303-5Q Beidou positioning chip. According to actual needs, it can also be other positioning chips. This application does not make specific limitations on this.

[0038] The storage module 212 can be used to store the acceleration data, the internal environmental parameters, the external environmental parameters, and the geographic location information to prevent data loss. In addition, when the refrigerated container passes through an area with poor network signals, such as inside a tunnel, the storage module can also be used to back up offline data.

[0039] The human-computer interaction module 213 can be used for the user to input the first control data. In a specific embodiment, the human-computer interaction module can be a human-computer interaction button, and the user can input the control data through the button. According to actual needs, the human-computer interaction module can also be a touch screen. This application does not make specific limitations on this.

[0040] The communication module 214 can be used to send the acceleration data, the internal environmental parameters, the external environmental parameters, and the geographic location information to the remote terminal, and receive the second control data sent by the remote terminal. In addition, the communication module 214 can also upload the offline data to the remote terminal. In a specific embodiment, the communication module can be the EG25-G chip developed by Quectel Communications. The EG25-G chip supports 4G network wireless communication and is compatible with existing EDGE and GSM / GPRS networks to ensure normal operation in remote areas lacking 3G and 4G networks. In some other embodiments, the communication module can also be other chips with remote communication capabilities, and the present application does not impose too many restrictions on this.

[0041] The prompt module 218 can be used to issue an alarm prompt according to the operating status of the backpack generator set or the refrigerated container. When the operating status of the backpack generator set or the refrigerated container is abnormal, the prompt module 218 will issue an alarm prompt. In a specific embodiment, the prompt module 21 may include a buzzer and an alarm light. According to actual needs, it can also be other devices with prompt functions. This application does not make specific limitations on this.

[0042] The control module 215 can be used to trigger control instructions for the backpack generator set. In a specific embodiment, the control module can be a GD32F303RBT6 main control chip. It can also be other chips according to actual needs. This application does not make specific limitations on this.

[0043] Next, we will combine Figure 3 , the control method of the refrigerated container power supply system based on railway transportation proposed in this application is elaborated in detail.

[0044] See also Figure 3 , a flow chart of a control method of a refrigerated container power supply system based on railway transportation in one embodiment of the present application is shown; as shown in the figure, the control method of a refrigerated container power supply system based on railway transportation proposed in the present application can be executed in the generator set controller as described above, and the method can at least include the following steps 310 to 320:

[0045] Step 310: Obtain a set control strategy for any one of the generator set controllers.

[0046] Step 320: Control the target backpack generator set to supply power to the refrigerated container according to the set control strategy, wherein the target backpack generator set is a backpack generator set corresponding to any one of the generator set controllers.

[0047] In the present application, by controlling the power supply action of the target backpack generator set to the refrigerated container according to the set control strategy, different control strategies can be set according to the different refrigeration requirements of the goods inside the refrigerated container, and different control strategies can be formulated according to the different environments in which the refrigerated container is located, thereby improving the flexibility of power supply control for the refrigerated container. In addition, the target backpack generator set is a backpack generator set corresponding to any one of the generator set controllers, that is, one generator set controller controls a corresponding backpack generator set, which can further improve the flexibility of power supply control for multiple refrigerated containers.

[0048] In the above step 310, the acquisition of the set control strategy for any one of the generator set controllers may be specifically performed according to the following steps 311 to 312:

[0049] Step 311, determining the control mode set by the user on the human-computer interaction module, wherein the control mode includes a local control mode and a remote control mode.

[0050] Step 312: Under the control mode, obtain a set control strategy for any one of the generator set controllers.

[0051] In the present application, the human-computer interaction module can specifically be a human-computer interaction button. The user can set the control mode of the generator set controller through the human-computer interaction button, and can also set the generator set controller to set the control strategy of the backpack generator set through the human-computer interaction button.

[0052] In the present application, by setting a local control mode and a remote control mode, local control and remote control of the power supply to the refrigerated container can be achieved, thereby improving the diversity of control modes and further improving the flexibility of the power supply control to the refrigerated container.

[0053] In the above step 312, in the control mode, the setting control strategy for any one of the generator set controllers is obtained, which can be specifically performed according to the following steps 3121 to 3122:

[0054] Step 3121: if the control mode is the local control mode, first control data input by the user is obtained through the human-computer interaction module, and a set control strategy for any one of the generator set controllers is determined by parsing the first control data.

[0055] Step 3122: If the control mode is the remote control mode, the second control data sent by the user is obtained through the communication module, and the set control strategy for any one of the generator set controllers is determined by parsing the second control data.

[0056] In the present application, it can be understood that the priority of the first control data is higher than that of the second control data. Specifically, for example, the generator set controller receives the second control data sent by the user through the remote terminal, and at the same time receives the first control data input by the user through the human-computer interaction module. The generator set controller will determine the set control strategy for any one of the generator set controllers according to the first control data. For example, when there is a conflict between the first control data and the second control data, the generator set controller will determine the set control strategy for any one of the generator set controllers according to the first control data. In this way, the control flexibility of the generator set controller can be improved, thereby improving the flexibility of the power supply control of the refrigerated container.

[0057] In the above step 320, the set control strategy may include a continuous power supply strategy, a cyclic power supply strategy, and an intelligent start-stop power supply strategy.

[0058] When the set control strategy is a continuous power supply strategy, the power supply action of the target backpack generator set to the refrigerated container is controlled according to the set control strategy, which can be specifically performed according to the following steps 3201 to 3202:

[0059] Step 3201, controlling the backpack generator set to continuously supply power to the refrigerated container.

[0060] Step 3202: upon receiving a stop power supply instruction, controlling the backpack generator set to stop supplying power to the refrigerated container.

[0061] When the set control strategy is a cyclic power supply strategy, the power supply action of the target backpack generator set to the refrigerated container is controlled according to the set control strategy, which can be specifically performed according to the following steps 3203 to 3206:

[0062] Step 3203, controlling the backpack generator set to supply power to the refrigerated container.

[0063] Step 3204: When the power supply duration reaches a first duration, control the backpack generator set to stop supplying power to the refrigerated container.

[0064] Step 3205: When the power supply is stopped for a second period of time, the backpack generator set is controlled to supply power to the refrigerated container.

[0065] Step 3206, when receiving the stop power supply instruction, control the backpack generator set to stop supplying power to the refrigerated container.

[0066] When the set control strategy is the intelligent start-stop power supply strategy, the power supply action of the target backpack generator set to the refrigerated container is controlled according to the set control strategy, which can be specifically performed according to the following steps 3207 to 3210:

[0067] Step 3207, obtaining the internal ambient temperature of the refrigerated container.

[0068] Step 3208: If the internal ambient temperature is higher than a first preset temperature, control the backpack generator set to supply power to the refrigerated container.

[0069] Step 3209: If the internal ambient temperature is lower than a second preset temperature, control the backpack generator set to stop supplying power to the refrigerated container, wherein the first preset temperature is greater than the second preset temperature.

[0070] Step 3210, when receiving the power supply stop instruction, control the backpack generator set to stop supplying power to the refrigerated container.

[0071] In the present application, the first duration may be specifically 30 minutes, and the second duration may be specifically 5 minutes. According to actual needs, the first duration and the second duration may also be other parameter values, and the present application does not make any specific limitation on this.

[0072] In the present application, the first preset temperature may be specifically -16°C, and the second preset temperature may be specifically -19°C. According to actual needs, the first preset temperature and the second preset temperature may also be other parameter values, and the present application does not make any specific limitation on this.

[0073] Next, we will combine Figure 4 The technical solution proposed in this application is described with a specific embodiment, see Figure 4 , shows a temperature variation curve of a refrigerated container in one embodiment of the present application.

[0074] In this embodiment, a backpack generator set is used to power a single refrigerated container. The generator set controller can be controlled in remote control mode, and control data can be sent through a remote terminal. The control strategy is set to an intelligent start-stop power supply strategy. The first preset temperature is -16°C and the second preset temperature is -19°C. During transportation, the internal temperature of the refrigerated container changes as follows: Figure 4As shown, at the beginning, the internal temperature of the refrigerated container is higher than -16°C. At this time, the generator set controller controls the backpack generator to continue to supply power to the refrigerated container until the temperature is reduced to -19°C. The generator set controller controls the backpack generator to stop supplying power to the refrigerated container. When the temperature gradually rises to -16°C, the generator set controller controls the backpack generator to supply power to the refrigerated container again until the temperature is reduced to -19°C. This cycle repeats. After the experiment, a command to stop power supply is issued through the remote terminal. The generator set controller controls the backpack generator to stop supplying power to the refrigerated container, and the temperature of the refrigerated container gradually returns to normal temperature.

[0075] In the present application, different setting control strategies can be selected according to the different goods in the refrigerated container. Specifically, when the goods in the refrigerated container need to be refrigerated for a long time, a continuous power supply strategy can be adopted. When the goods in the refrigerated container are not sensitive to temperature changes, a circulating power supply strategy can be adopted. When the goods in the refrigerated container need to be kept within a certain temperature range, an intelligent start-stop power supply strategy can be adopted. In this way, the flexibility of power supply control of the refrigerated container can be further improved.

[0076] Based on the method proposed in the present application, in the process of controlling the target backpack generator set to supply power to the refrigerated container, the following steps 330 to 340 may be specifically performed:

[0077] Step 330: Acquire the internal environmental parameters of the internal environment of the refrigerated container and the external environmental parameters of the external environment collected by the environmental data collection module.

[0078] Step 340: Control the power supplied by the target backpack generator set to the refrigerated container according to the internal environmental parameters and the external environmental parameters.

[0079] In the present application, the internal environmental parameter may specifically be the internal temperature of the refrigerated container, and the external environmental parameter may specifically be the ambient temperature outside the refrigerated container.

[0080] In the present application, the power supplied to the refrigerated container by the target backpack generator set is controlled according to the internal environmental parameters and the external environmental parameters. Specifically, for example, when the internal temperature of the refrigerated container is high, the target backpack generator set can be controlled to increase the power supplied to the refrigerated container. When the internal temperature of the refrigerated container rises rapidly, the target backpack generator set can also be controlled to increase the power supplied to the refrigerated container. When the external ambient temperature of the refrigerated container is high, the target backpack generator set can also be controlled to increase the power supplied to the refrigerated container. That is, the internal temperature and the external ambient temperature of the refrigerated container are positively correlated with the power supplied to the refrigerated container by the target backpack generator set. Based on this, controlling the power supplied to the refrigerated container by the target backpack generator set according to the internal temperature and the external ambient temperature can improve the flexibility of power supply control to the refrigerated container.

[0081] Based on the method proposed in the present application, in the process of controlling the target backpack generator set to supply power to the refrigerated container, the following steps 350 to 360 may be specifically performed:

[0082] Step 350: Acquire the geographic location information of the refrigerated container collected by the positioning module.

[0083] Step 360: Control the power supplied by the target backpack generator set to the refrigerated container according to the geographic location information.

[0084] In the present application, the geographic location information may specifically include the latitude and longitude, poster height and weather conditions of the area where the refrigerated container is located.

[0085] In the present application, the power supplied to the refrigerated container by the target backpack generator set is controlled according to the geographic location information. Specifically, for example, when the weather condition in the area where the refrigerated container is located is sunny and the temperature is high, the target backpack generator set can be controlled to increase the power supplied to the refrigerated container; when the weather condition in the area where the refrigerated container is located is rainy and the temperature is low, the target backpack generator set can be controlled to reduce the power supplied to the refrigerated container; when the altitude of the area where the refrigerated container is located is high, the target backpack generator set can be controlled to increase the power supplied to the refrigerated container; when the latitude of the area where the refrigerated container is located is low, the target backpack generator set can be controlled to increase the power supplied to the refrigerated container. Based on this, controlling the power supplied to the refrigerated container by the target backpack generator set according to the geographic location information can improve the flexibility of power supply control for the refrigerated container.

[0086] Based on the technical solution proposed in the present application, by controlling the power supply action of the target backpack generator set to the refrigerated container according to the set control strategy, different control strategies can be set according to the different refrigeration requirements of the goods inside the refrigerated container, and different control strategies can be formulated according to the different environments in which the refrigerated container is located, thereby improving the flexibility of power supply control for the refrigerated container. In addition, the target backpack generator set is the backpack generator set corresponding to any one of the generator set controllers, that is, one generator set controller controls a corresponding backpack generator set, which can further improve the flexibility of power supply control for multiple refrigerated containers.
