Abstract
Description
Technical Field
[0001] This application relates to the field of product transportation technology, and in particular to a logistics transportation method, system and storage medium. Background Technology
[0002] In the current logistics and transportation industry, mobile cargo carts are often used to move goods. Logistics warehouses typically use shelving for storage, and when goods are received in batches, forklifts are used to lift pallets and place them in designated areas on the shelving, thus facilitating the handling of the target goods. With continuous social progress and development, more and more emerging industries are appearing, such as the new energy industry, the electronics industry, and the e-commerce industry. To ensure the stable development of these industries, a stable supply of goods becomes crucial. Therefore, cargo transportation has become a vital link in the development of these industries. Taking the new energy industry as an example, the new energy industry has become increasingly accepted by consumers in recent years. Lithium-ion battery packs are a type of new energy source, boasting advantages such as small size, long battery life, and fast charging. After processing, lithium-ion batteries need to be stacked and arranged in warehouses. Many large lithium-ion battery manufacturers have established automated warehouses. However, due to the inherent characteristics of lithium-ion batteries, once ignited, the instantaneous temperature can reach as high as 1000 degrees Celsius. Furthermore, when lithium-ion batteries are stacked at high density, they are highly susceptible to spontaneous combustion of surrounding batteries, potentially causing incalculable losses. Therefore, fire prevention measures are essential during the storage of lithium-ion battery packs.
[0003] In related technologies, when faced with a lithium-ion battery fire, the warehouse management system controls sprinkler heads to spray water to extinguish the fire. However, this method can only extinguish the fire at the ignition point. If the ignition point explodes, it will not only increase the damage rate of goods, but also threaten the safety of personnel. Therefore, it is particularly important to prevent other lithium-ion batteries from being affected when a lithium-ion battery is burning. Summary of the Invention

[0053] With continuous social progress and development, the new energy industry has become increasingly accepted by consumers in recent years. Lithium-ion battery packs are one type of new energy source, boasting advantages such as small size, long service life, and fast charging. After processing, lithium-ion batteries need to be stacked and arranged in warehouses. Many large lithium-ion battery manufacturers have established automated warehouses. However, due to the inherent characteristics of lithium-ion batteries, once ignited, the instantaneous temperature can reach as high as 1000 degrees Celsius. Furthermore, when lithium-ion batteries are stacked at high density, they are highly susceptible to spontaneous combustion of surrounding lithium-ion batteries, leading to incalculable losses. Therefore, fire prevention is crucial during the storage of lithium-ion battery packs.
[0054] In related technologies, when faced with a lithium-ion battery fire, the warehouse management system controls sprinkler heads to spray water to extinguish the fire. However, this method can only extinguish the fire at the ignition point. If the ignition point explodes, it will not only increase the damage rate of goods, but also threaten the safety of personnel. Therefore, it is particularly important to prevent other lithium-ion batteries from being affected when a lithium-ion battery is burning.
[0055] To address the aforementioned issues, this embodiment proposes a logistics transportation method, system, and storage medium. First, it receives a detection signal from a storage location device to determine if a fire has occurred within the device. Based on the detection signal, it generates control commands to extinguish the fire and transfer the goods within the storage location. Next, it sends control commands to a stacking device and receives status information returned by the device based on these commands. This allows it to determine the current load-bearing status of the stacking device, preventing it from running empty despite being fully loaded, thus improving the efficiency of goods transfer. Finally, when the status information indicates that the stacking device is empty, it controls the device to move to the storage location to retrieve the target goods from the individual storage location, thereby achieving the transfer of the target goods and avoiding impact on surrounding goods, reducing the damage rate.
[0056] Please refer to Figures 1-2 , Figure 1 This is a schematic diagram of the logistics transportation system provided in the embodiments of this application; Figure 2 This is a schematic diagram of the storage location device provided in the embodiments of this application;
[0057] refer to Figure 1 In some embodiments, the logistics transportation system includes:
[0058] Storage location device 100 includes multiple individual storage locations 110, and storage location device 100 is used to send detection signals;
[0059] refer to Figure 3 , Figure 3 yes Figure 2 A magnified view of part A in the middle;
[0060] In some embodiments, the individual storage compartment 110 is a cavity structure with one open side, and the individual storage compartment 110 is provided with a spray device 111 for spraying liquid, a smoke sensor 112 for detecting the smoke concentration in the individual storage compartment 110, and a temperature sensor 113 for detecting the temperature in the individual storage compartment 110. The spray device 111, the smoke sensor 112, and the temperature sensor 113 are all communicatively connected to the controller, thereby sending detection signals to the controller.
[0061] It is understood that the detection signal in this embodiment is generated based on the detection results of the temperature sensor 113 or the smoke sensor 112.
[0062] refer to Figure 4 , Figure 4 This is a schematic diagram of the storage location device 100 provided in another embodiment of this application;
[0063] It should be noted that the individual storage location 110 is also equipped with a pallet support 114, on which goods are placed to facilitate the stacking device's retrieval and speed up the retrieval efficiency. Furthermore, the inner wall of the cavity of the individual storage location 110 is sealed with fireproof material. When the temperature sensor 113 or the smoke sensor 112 detects an abnormality, the detection signal is fed back to the controller so that the controller can take further action, thereby realizing real-time monitoring of the individual storage location 110.
[0064] refer to Figure 5 , Figure 5 yes Figure 4 A magnified view of part B in the middle section;
[0065] It is worth noting that, in this embodiment, the temperature sensor 113, the smoke sensor 112, and the spray device 111 can be installed at any location in the unit storage location 110 except the bottom, for example, at the top of the unit storage location 110, on the side wall of the unit storage location 110, etc. Figure 3 Taking the top of the individual storage location 110 as an example, in this embodiment, the temperature sensor 113 is set in an O-shape in the individual storage location 110, so as to obtain the temperature at any position in the individual storage location 110, realize the real-time detection of the temperature in the individual storage location 110, improve the accuracy of the temperature detection in the individual storage location 110, and further improve the safety of the individual storage location 110.
[0066] In addition, a humidity sensor can be installed in the individual storage location 110 in this embodiment to detect the humidity in the individual storage location 110 and avoid situations such as damp air or leakage.
[0067] It is understood that the spray device 111 in this embodiment includes, but is not limited to, spray heads, spray pipes, etc., the smoke sensor 112 includes, but is not limited to, photoelectric ionization smoke sensor 112, ionization smoke sensor, spectral smoke sensor 112, etc., and the temperature sensor 113 includes, but is not limited to, thermistor temperature sensor 113, infrared temperature sensor 113, resistance temperature sensor 113, etc., and this embodiment does not impose specific limitations.
[0068] Stacking device 200 is used to move to storage device 100 in an unloaded state to retrieve target goods in individual storage location 110;
[0069] It should be noted that the cargo in this embodiment is a lithium-ion battery pack, and the target cargo is a lithium-ion battery that has shown signs of combustion, i.e., the ignition point referred to in this embodiment.
[0070] The controller 300 is communicatively connected to the storage location device 100 and the stacking device 200. The controller is used to receive the detection signal sent by the storage location device 100 and generate control commands based on the detection signal; send control commands to the stacking device 200 and receive the status information returned by the stacking device 200 based on the control commands; when the status information indicates that the stacking device 200 is in an empty state, the controller controls the stacking device 200 to move to the storage location device 100 to retrieve the target goods of the individual storage location 110.
[0071] In addition, the logistics transportation system also includes an explosion-proof device 400. After the stacking device 200 recovers the individual storage location 110, the controller controls the stacking device 200 to move to the explosion-proof device 400, thereby placing the target goods into the explosion-proof device 400 to avoid the target goods from exploding and affecting the safety of personnel and other goods.
[0072] It should be noted that the explosion-proof device 400 can be an explosion-proof box, explosion-proof cabinet, or explosion-proof enclosure, etc. The explosion-proof material of the explosion-proof device 400 includes, but is not limited to, steel plates and silicate boards, with the steel plate encasing the silicate board inside. When the goods catch fire, the steel plate blocks the flames. If the flame temperature is too high and burns through the steel plate, the silicate board will block the flames a second time, thereby extending the firefighting time and allowing more time for firefighting, and preventing the fire from affecting the goods around the ignition point.
[0073] In some embodiments, the storage unit 100 further includes a hollow shelf 120 for supporting the individual storage unit 110. The bottom of the individual storage unit 110 is provided with a guide channel 130, which is used to guide the liquid sprayed by the sprinkler device 111 to the hollow shelf 120. The hollow shelf 120 is also used to discharge the liquid that flows through it, thereby realizing the circulation and discharge of the liquid sprayed by the sprinkler device 111, improving the speed of fire extinguishing and cooling, and enabling the original state to be quickly restored after the fire is extinguished, without having to spend a lot of time and effort to clean up the site, saving time and effort.
[0074] It should be noted that in the event of a fire involving the target goods, the sprinkler system 111 will spray the liquid. The diversion channel can guide the sprayed liquid into the hollow rack 120, which acts as a drain pipe to drain the water to the ground. A drainage trough 150 is also provided on the ground, which is connected to the hollow rack 120 through the diversion channel 140, so that the water will not be directly drained to the ground, thus enabling the site to be quickly restored without the need for manual cleaning.
[0075] refer to Figure 6 ,Figure 6 This is a schematic diagram of the stacking device 200 provided in the embodiments of this application;
[0076] In some embodiments, the stacking device 200 includes a loading platform 210 for carrying goods and a transfer device 220 for moving goods. The loading platform 210 is a cavity structure with one open side, and a fireproof curtain 230 for fire prevention is also provided at the opening of the loading platform 210. A dry ice spraying device is also provided inside the cavity of the loading platform 210 to cool the inside of the cavity, thereby enabling the transfer of the target goods. The dry ice spraying device also enables the cavity of the loading platform 210 to cool down quickly, thereby avoiding damage to the loading platform 210 by high temperature and enabling rapid transfer of the fire point.
[0077] It should be noted that the loading platform 210 of the stacking device 200 has an opening, and the rest of the walls are completely sealed. A fireproof curtain 230 is installed at the opening to avoid being affected by the high temperature of the target goods, and to avoid the target goods from affecting the surrounding environment during the transfer of the target goods.
[0078] It is understood that the transfer device 220 in this embodiment includes, but is not limited to, grippers, pliers, pallet clamps, forks, etc., and the fire curtain 230 is made of materials including, but not limited to, fiberglass cloth, fire-resistant coated cloth, fire-resistant silicone cloth, etc. The fire curtain 230 can be a switchable fire curtain, a fire-resistant roller shutter, etc., and this embodiment does not impose specific limitations.
[0079] In some embodiments, the stacking device 200 further includes a laser positioning unit and a sensor positioning unit. The laser positioning unit uses a combination of optical communication and a laser sensor for positioning, while the sensor positioning unit uses a combination of wireless communication and a sensor for positioning. Under normal circumstances, the stacking device 200 operates using the laser positioning unit; in the event of a fire or smoke, the stacking device 200 operates using the sensor positioning unit.
[0080] Under normal circumstances, excluding fire and smoke conditions, i.e., when environmental visibility is high, the sensing and positioning unit can use sensors such as visual sensors, ultrasonic sensors, and inertial measurement sensors for positioning. This embodiment does not impose any specific limitations.
[0081] Based on the structure of the logistics and transportation system described above, the logistics and transportation method of this application embodiment will be described in detail below.
[0082] Please refer to Figure 7 , Figure 7This is a flowchart of a specific method of the logistics transportation method provided in the embodiments of this application. It is applied, but not limited to, the logistics transportation system described above. In some embodiments, the logistics transportation method includes, but is not limited to, steps S101 to S103.
[0083] Step S101: Receive the detection signal sent by the storage location device and generate a control command based on the detection signal;
[0084] In some embodiments, a detection signal sent by the storage location device is received to determine whether the goods in the individual storage location need to be transferred, and a control command is generated based on the detection signal to control the stacking device to transfer the goods if it is determined that the goods in the individual storage location need to be transferred.
[0085] Step S102: Send a control command to the stacking device and receive the status information returned by the stacking device according to the control command;
[0086] In some embodiments, control commands are sent to the stacking device, and status information returned by the stacking device according to the control commands is received, thereby determining the current loading status of the stacking device, avoiding the situation where a fully loaded stacking device is used to transport the target goods, and also avoiding the situation where other goods in the stacking device are affected by the target goods, thereby improving the handling efficiency of goods.
[0087] Step S103: When the status information indicates that the stacking device is in an unloaded state, control the stacking device to move to the storage location device to retrieve the target goods of the individual storage location.
[0088] In some embodiments, when the status information indicates that the stacking device is in an unloaded state, it means that the loading platform in the stacking device is empty. In this case, the stacking device can be controlled to move to the storage location to recover the target goods of the individual storage location, thereby realizing the recovery of the goods at the fire point, avoiding the impact of the fire point on the surrounding goods, and reducing losses.
[0089] It is worth noting that before sending control commands to the stacking device, it is also necessary to assess the environment around the storage location device, calculate the distance between the stacking devices around the storage location device and the storage location device, compare multiple distance paths, select the stacking device that is closer to the storage location device, and send control commands to the closer stacking device, thereby improving the speed of handling the target goods and ensuring the safety of other goods.
[0090] It should be noted that the target cargo in this embodiment is the cargo at the point of ignition.
[0091] Please refer to Figure 8 , Figure 8 This is a flowchart of a specific method of a logistics transportation method provided in another embodiment of this application. In some embodiments, the logistics transportation method includes, but is not limited to, steps S201 to S204.
[0092] Step S201: When the status information indicates that the stacking device is in a loaded state, obtain the environmental information around the stacking device and determine the empty cargo location based on the environmental information.
[0093] Step S202: Control the stacking device to move to the empty storage location to move the pre-loaded goods to the empty storage location;
[0094] Step S203: Receive the current status information sent by the stacking device after the goods handling is completed;
[0095] Step S204: If the current status information indicates that the stacking device is in an unloaded state, control the stacking device to move to the storage location device to retrieve the target goods of the individual storage location.
[0096] In some embodiments, when the status information indicates that the stacking device is in a loaded state, it is necessary to obtain the environmental information around the stacking device, determine the empty storage location based on the environmental information, and then control the stacking device to move to the empty storage location to move the goods it is pre-loaded to the empty storage location. The stacking device updates its own status information. Then, it receives the current status information sent by the stacking device after the goods are moved, and judges the current status information to determine whether the loading platform of the stacking device is empty. If the current status information indicates that the stacking device is in an empty state, it controls the stacking device to move to the storage location to retrieve the target goods of the single storage location, thereby realizing the transfer of the target goods, avoiding affecting the goods around the target goods, and reducing the damage rate of the goods.
[0097] It should be noted that when there are multiple ignition points and multiple stacking devices, control commands are sent to multiple stacking devices simultaneously to obtain their status information. Based on the status information, the stacking devices are divided into a first stacking device and a second stacking device. The first stacking device is in an empty state, and the second stacking device is in a loaded state. The first stacking device, which is in an empty state, is directly controlled to move to the storage location to retrieve the target goods. At the same time, the second stacking device, which is in a loaded state, is controlled to move to an empty storage location near itself to place the goods. After the goods are moved, the stacking device is controlled to move to an empty storage location to retrieve the target goods. This completes the judgment of the stacking device status and improves the response speed of the stacking device to the ignition point.
[0098] Please refer to Figure 9 , Figure 9 This is a flowchart of a specific method for step S103 provided in the embodiments of this application. Step S103 includes, but is not limited to, steps S301 to S303.
[0099] Step S301: Control the stacking device to move to the storage location device, and perform open flame detection on the individual storage location to obtain the detection result;
[0100] Step S302: When the detection result indicates that there is an open flame in the individual storage location, start the sprinkler system to extinguish the fire until the open flame is extinguished.
[0101] Step S303: Control the stacking device to recover the target goods in the individual storage location.
[0102] In some embodiments, the stacking device is controlled to move to the storage location and an open flame detection is performed on the individual storage location. If the detection result indicates that there is an open flame in the individual storage location, the stacking device will not perform the outbound task. Instead, the spraying device needs to be activated to spray liquid until the open flame disappears, in order to prevent the stacking device from being burned. After confirming that the open flame has disappeared, the stacking device is controlled to retrieve the target goods from the individual storage location, thereby realizing the handling of the target goods.
[0103] It should be noted that in this embodiment, open flames can be detected by flame sensors, infrared sensors, and visual monitoring sensors; no specific limitations are imposed in this embodiment.
[0104] In some embodiments, when the detection result indicates that there is no open flame in a single storage location, the stacking device can be directly controlled to recover the target goods in the single storage location.
[0105] Please refer to Figure 10 , Figure 10 This is a flowchart of a specific method for step S303 provided in the embodiments of this application. Step S303 includes, but is not limited to, steps S401 to S402.
[0106] Step S401: Receive the concentration value sent by the smoke sensor;
[0107] It should be noted that the concentration values are obtained by the smoke sensor detecting the smoke concentration in the individual storage location.
[0108] In step S402, when the concentration value is less than or equal to the preset smoke value, the stacking device is controlled to locate the target goods through the laser positioning unit to obtain the first position information, and the target goods are recycled according to the first position information.
[0109] In some embodiments, the smoke sensor detects the smoke concentration value of the current individual storage location to obtain the smoke concentration of the individual storage location under the current condition. If the concentration value is less than or equal to a preset smoke value, the stacking device is controlled to use a laser positioning unit to locate the target goods and obtain the first position information obtained by laser positioning, thereby determining the specific location of the target goods and recovering the target goods according to the first position information, thereby achieving accurate identification of the target goods.
[0110] It should be noted that during the process of locating the target cargo using the laser positioning unit, signals are received via optical communication. First, a laser beam is emitted by the laser sensor, and the signal reflected back from the target cargo by the laser beam is received. Then, the travel time of the laser beam is calculated by measuring the time between the emission and reception of the laser beam. Finally, the distance between the target cargo and the laser sensor is calculated based on the travel time and the known laser speed. The three-dimensional coordinate position of the target cargo is determined by the combination of multiple laser sensors, generating the first position information.
[0111] Please refer to Figure 11 , Figure 11 This is another flowchart of the specific method of step S303 provided in the embodiments of this application. Step S303 includes, but is not limited to, step S501.
[0112] Step S501: When the concentration value is greater than the preset smoke value, the stacking device is controlled to locate the target goods through the sensing and positioning unit to obtain the second location information, and the target goods are recycled according to the second location information.
[0113] In some embodiments, when the concentration value is greater than a preset smoke value, it indicates that the air visibility is low. It is necessary to control the stacking device to use the sensing and positioning unit to locate the target goods, obtain the second location information, and recover the target goods based on the second location information. This enables accurate identification of the target goods in the event of a fire or smoke, improves the efficiency of transferring the target goods, and reduces the probability of surrounding goods being affected.
[0114] It should be noted that during the process of locating the target cargo using the sensing and positioning unit, the position is measured wirelessly. For example, positioning can be achieved using inertial measurement sensors, that is, by measuring the acceleration and angular velocity of the object using sensors such as accelerometers and gyroscopes, and then calculating the position of the object by integration, etc.
[0115] Please refer to Figure 12 , Figure 12 This is a flowchart of a specific method of a logistics transportation method provided in another embodiment of this application. In some embodiments, the logistics transportation method includes, but is not limited to, steps S601 to S602.
[0116] Step S601: Calculate the distance between the stacking device and the explosion-proof device, and generate the target path;
[0117] Step S602: Control the stacking device to move along the target path to the explosion-proof device and place the target goods in the explosion-proof device.
[0118] In some embodiments, after controlling the stacking device to retrieve the target goods in a single storage location, it is also necessary to calculate the distance between the stacking device and the explosion-proof device, generate a target path, and then control the stacking device to move along the target path to the explosion-proof device and place the target goods in the explosion-proof device, thereby preventing the target goods from exploding or burning, realizing the transfer of the ignition point, and avoiding affecting the goods in other single storage locations.
[0119] It should be noted that in the process of calculating the distance between the stacking device and the explosion-proof device, the distance between the two can be measured by ultrasonic sensors or distance sensors to determine the relative position and distance between the two devices. Then, a path planning algorithm is used to generate the target path to avoid obstacles during the movement and achieve rapid movement of the target goods.
[0120] It is understandable that path planning algorithms include, but are not limited to, shortest path algorithms, A* algorithms, and so on.
