[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0029] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.
[0030] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.
[0031] In this application, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0032] First, it's important to clarify that a Liquefied Gas Tanker Truck (LPG truck), also known as an LPG tanker or LPG transport truck, is a specialized vehicle used to transport liquefied gases such as propane, propylene, dimethyl ether, liquid ammonia, methylamine, and acetaldehyde. Because transporting liquefied gases using these tankers is inherently a high-risk operation, improper operation or management during transport can easily lead to accidents of varying degrees. Furthermore, improper operation or a lack of safety awareness by personnel can easily result in leaks and theft. Therefore, a proper unloading control method is urgently needed to ensure that leaks and theft do not occur during the unloading process.
[0033] Figure 1 This is a schematic diagram illustrating an implementation environment for unloading control of a liquefied gas transport vehicle, as shown in an exemplary embodiment of this application. Figure 1As shown, when the liquefied gas transport vehicle arrives at the target unloading location, its onboard terminal 110 sends an unloading request to the control server 120. Upon receiving the unloading request, the control server 120 obtains the current location information of the liquefied gas transport vehicle and the location information of the requested unloading area. It then determines whether the current location information of the liquefied gas transport vehicle and the location information of the requested unloading area match. If they match, an unloading start command is generated and sent to the onboard terminal 110, enabling the onboard terminal 110 to open the unloading device of the liquefied gas transport vehicle upon receiving the unloading start command, thus initiating unloading. During the unloading process, if the control server 120 detects an abnormal unloading situation, it generates an unloading stop command and sends it to the onboard terminal 110, allowing the vehicle terminal 110 to control the liquefied gas transport vehicle to close the unloading device and stop unloading.
[0034] in, Figure 1 The vehicle terminal 110 can be any terminal device that supports the installation of navigation map software, such as a smartphone, vehicle computer, tablet computer, laptop computer, or wearable device, but is not limited to these. Figure 1 The control server 120 shown is a control server, which can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. No restrictions are placed on this. The vehicle terminal 110 can communicate with the control server 120 via wireless networks such as 3G (third-generation mobile information technology), 4G (fourth-generation mobile information technology), and 5G (fifth-generation mobile information technology). No restrictions are placed on this as well.
[0035] During the transportation of liquefied gas using liquefied gas transport vehicles, improper use and management of the transport operation control box can easily lead to safety accidents of varying degrees. In reality, safety accidents caused by improper use and management of vehicle control boxes occur frequently, even resulting in personal injury and property damage. Although existing tank trucks are equipped with some unloading control systems, most unloading operations are still manually performed by the tank truck owner or the corresponding unloading operator. This unloading operation control is prone to certain safety hazards, including human error, and in serious cases, the medium transported by the tank truck may be unloaded to other locations, or there may be theft or leakage during the unloading process.
[0036] The problems mentioned above are universally applicable in the transportation of liquefied gas using common liquefied gas transport vehicles. To address these problems, embodiments of this application propose a liquid unloading control method, a liquid unloading control device, an electronic device, a computer-readable storage medium, and a computer program product, which will be described in detail below.
[0037] Please see Figure 2 , Figure 2 This is a flowchart illustrating an exemplary embodiment of the unloading control method of this application. The method can be applied to... Figure 1 The implementation environment shown is specifically executed by the control server 120 within that implementation environment. It should be understood that this method can also be applied to other exemplary implementation environments and executed by devices in other implementation environments. This embodiment does not limit the implementation environment to which this method is applicable.
[0038] like Figure 2 As shown, in an exemplary embodiment, the liquid unloading control method includes at least steps S210 to S250, which are described in detail below:
[0039] Step S210: Receive the unloading request sent by the unloading device.
[0040] Specifically, when a liquefied gas transport vehicle arrives at the target unloading location, the driver or relevant operators will send an unloading request to the control server. This unloading request may include the area to be unloaded and the total amount of gas to be unloaded.
[0041] In addition, in some feasible implementation schemes, the driver or on-site operator can log in to the vehicle terminal using a unique identifier, such as a user account, fingerprint, or password, and then send a liquid unloading request to the control server according to the actual liquid unloading needs.
[0042] Step S220: If the location information of the unloading device and the location information of the requested unloading area are detected to match based on the unloading request, an unloading start command is generated.
[0043] Specifically, upon receiving a liquid unloading request from the liquid unloading device, the system obtains the current location information of the device that sent the request. This can include the GPS signal of the vehicle-mounted terminal corresponding to the request, or, in some feasible embodiments, the liquid unloading request sent by the vehicle-mounted terminal to the control server may include the current location information of the liquid unloading device. Simultaneously, the system obtains the location information of the requested liquid unloading area corresponding to the request and checks whether the location information of the liquid unloading device matches the location information of the requested liquid unloading area. If the location information of the liquid unloading device matches the location information of the requested liquid unloading area, a liquid unloading start command is generated.
[0044] In some feasible implementations, the control server stores the target unloading area corresponding to the unloading equipment. Specifically, it can detect whether the location information of the requested unloading area corresponding to the unloading request matches the location information of the target unloading area of the unloading equipment, and whether the current location information of the unloading equipment matches the location information of the target unloading area. This application does not impose any limitations on this.
[0045] Step S230: Send the unloading start command to the unloading equipment so that the unloading equipment can open the unloading device based on the unloading start command, so as to unload the liquid through the opened unloading device.
[0046] Specifically, the unloading start command is sent to the vehicle-mounted terminal corresponding to the unloading request, so that the unloading equipment starts the unloading device to unload under the guidance of the unloading start command from the vehicle-mounted terminal. For example, after receiving the unloading start command sent by the control server, the vehicle-mounted terminal of the unloading equipment opens the unloading valve to start unloading, and at the start of unloading, the flow meter in the unloading equipment is turned on to record the unloading volume in real time.
[0047] Step S240: If an abnormal situation is detected during the unloading process, an unloading shutdown command is generated.
[0048] Specifically, during the unloading process, the control server monitors the unloading status in real time. When an abnormal unloading situation is detected, an unloading shutdown command is generated and sent to the unloading equipment. For example, during the unloading process, the control server monitors the unloading status and generates an unloading shutdown command if abnormal situations occur, such as the total unloading volume not meeting the target volume in the unloading request, unloading pipeline malfunction, vehicle terminal malfunction, or flow meter malfunction, to prevent safety hazards caused by the abnormal unloading situation.
[0049] Step S250: Send a liquid discharge shutdown command to the liquid discharge equipment so that the liquid discharge equipment shuts down the liquid discharger based on the liquid discharge shutdown command, thereby stopping liquid discharge through the shut-down liquid discharger.
[0050] Specifically, a liquid discharge shutdown command is sent to the vehicle-mounted terminal of the liquid discharge equipment, so that the liquid discharge equipment closes the unloading device and stops discharging liquid upon receiving the liquid discharge shutdown command from the vehicle-mounted terminal. For example, after the vehicle terminal of the liquid discharge equipment receives the liquid discharge shutdown command sent by the control server, it closes the unloading device and reports the total amount of liquid remaining in the liquid discharge equipment at this time.
[0051] In this embodiment, upon receiving a liquid unloading request from the unloading equipment, and detecting a match between the location information of the unloading equipment and the location information of the requested unloading area, a liquid unloading command is generated and sent to the unloading equipment, causing it to activate the unloading device to unload the liquid. This ensures the accuracy of the unloading location and the efficiency of the unloading process. Furthermore, if an abnormality occurs during the unloading process, a liquid unloading shutdown command is generated and sent to the unloading equipment, enabling it to promptly shut down the unloading device and stop unloading, thus avoiding safety hazards caused by abnormalities and effectively preventing leakage or theft.
[0052] Furthermore, based on the above embodiments, please refer to... Figure 3 In one exemplary embodiment provided in this application, the implementation process of the above-described unloading control method may further include steps S310 and S320, which are described in detail below:
[0053] Step S310: During the unloading process, obtain the location information of the unloading equipment and the location information of the unloading area.
[0054] Specifically, during the unloading process, the control server continuously monitors the location information of the unloading equipment. This can be achieved by the unloading equipment reporting its location information to the control server, for example, by sharing its location information with the control server. The control terminal then checks whether the current location information of the unloading equipment matches the location information of the unloading request area in the unloading request. Alternatively, in some feasible implementations, the control server obtains the pre-set target unloading area for the unloading equipment and determines whether the current location information of the unloading equipment matches the location information of the target unloading area.
[0055] Step S320: If the obtained location information of the unloading equipment and the obtained location information of the unloading area do not match, a detection result is obtained to characterize the existence of an abnormal unloading situation during the unloading process.
[0056] Specifically, if the current location information of the unloading equipment does not match the location information of the requested unloading area in the unloading request, or if the current location information of the unloading equipment does not match the location information of the pre-set target unloading area, then the unloading equipment may be unloading in the wrong place, or even more seriously, unloading may be unloading in a place that does not meet the unloading conditions. This indicates that the current unloading situation is abnormal and may pose a safety hazard during the unloading process. Therefore, this condition is used to characterize the unloading equipment's abnormal unloading operation.
[0057] In this embodiment, by acquiring the location information of the unloading equipment and the location information of the unloading area during the unloading process, if a mismatch is detected between the location information of the unloading equipment and the location information of the unloading area, a detection result can be obtained to characterize the existence of an abnormal unloading situation during the unloading process. This can effectively manage the unloading process of the unloading equipment and effectively avoid safety hazards caused by a mismatch between the location information of the unloading equipment and the location information of the unloading area.
[0058] Furthermore, based on the above embodiments, please refer to... Figure 4 In one exemplary embodiment provided in this application, the implementation process of the above-mentioned unloading control method further includes steps S410 and S420, which are described in detail below:
[0059] Step S410: During the unloading process, acquire unloading information of the unloading equipment and liquid increase information of the unloading area; wherein, the unloading information of the unloading equipment is used to characterize the unloading situation of the unloading equipment, and the liquid increase information of the unloading area is used to characterize the liquid increase situation of the unloading area.
[0060] Specifically, during the unloading process of the unloading equipment, unloading information and liquid increase information of the unloading area are acquired. For example, during the unloading process, the flow meter in the unloading equipment measures the total amount of liquid unloaded in real time. The unloading information of the unloading equipment can be determined by acquiring the total unloading volume recorded by the flow meter, which characterizes the unloading situation of the corresponding unloading equipment. Furthermore, the liquid increase situation of the unloading area is acquired by using the liquid sensor corresponding to the unloading area, where the liquid increase information characterizes the liquid increase situation of the unloading area.
[0061] Step S420: If the unloading information of the unloading equipment and the liquid increase information of the unloading area are not matched, a detection result is obtained to characterize the existence of an abnormal unloading situation during the unloading process.
[0062] Specifically, the detection involves checking whether the unloading information of the unloading equipment matches the corresponding liquid increase information of the unloading area. For example, this can be achieved by comparing the total unloading volume recorded by the flow meter in the unloading equipment with the total liquid increase obtained in the unloading area. If the total unloading volume of the unloading equipment and the total liquid increase in the unloading area do not match within the allowable error range, it indicates that there may be a safety hazard of leakage or liquid theft during the unloading process. Therefore, a detection result can be obtained to characterize the occurrence of an abnormal unloading situation during the unloading process.
[0063] In this embodiment, when a mismatch is detected between the unloading information of the unloading equipment and the liquid replenishment information of the unloading area during the unloading process, a detection result is obtained to characterize the existence of an abnormal unloading situation during the unloading process. This results in the generation of an unloading stop command to stop the unloading process of the unloading equipment, thereby effectively preventing liquid theft and leakage during the unloading process.
[0064] Furthermore, in some feasible implementations, if the unloading information of the unloading device is detected to match the target unloading information in the unloading request, a check result characterizing the completion of the unloading process is obtained, and an unloading stop command is generated based on the check result. For example, during the unloading process, the unloading information of the unloading device is obtained through the flow meter of the unloading device, and it is determined whether the unloading information matches the target unloading information in the unloading request sent by the unloading device. If the unloading information matches the target unloading information, it indicates that the unloading device has completed the corresponding target unloading information in the unloading request and can stop unloading, thereby obtaining a check result characterizing the completion of unloading by the unloading device, and generating a unloading stop command based on the check result of the unloading device's completion.
[0065] In this embodiment, when the unloading information of the unloading equipment matches the target unloading information in the unloading request, a detection result is obtained to characterize the completion of the unloading process. Based on the detection result of the unloading completion, an unloading shutdown command is generated, which effectively prevents the unloading equipment from leaking or unloading too much liquid during the unloading process.
[0066] Furthermore, based on the above embodiments, please refer to... Figure 5 In one exemplary embodiment provided in this application, the specific implementation process of the above-mentioned unloading control method may further include steps S510 to S530, which are described in detail below:
[0067] Step S510: After unloading is completed, obtain the total amount of liquid unloaded by the unloading equipment and the total amount of liquid unloaded corresponding to the unloading request.
[0068] Unloading completion can occur when the driver or relevant operators send an unloading completion request to the control server, or when the unloading equipment stops unloading due to an abnormality during the unloading process. After the unloading equipment completes unloading, the total unloaded volume and the corresponding unloaded volume in the unloading request are obtained. For example, the total unloaded volume can be calculated based on the unloading flow rate recorded by the flow meter in the unloading equipment.
[0069] Step S520: If the total amount of liquid unloaded by the unloading device does not match the total amount of liquid unloaded corresponding to the unloading request, an alarm message is generated.
[0070] An alarm is generated when the total amount of liquid unloaded by the unloading equipment does not match the total amount of liquid unloaded in the unloading request sent to the control server. In some feasible implementations, the total amount of liquid unloaded by the unloading equipment is compared with the target total amount of liquid unloaded by the unloading equipment in the current unloading area obtained from the control server. If they do not match, an alarm is generated.
[0071] Step S530: Send the alarm information to the designated terminal device so that the designated terminal device can control the unloading equipment based on the alarm information.
[0072] Specifically, an alarm message indicating that the total amount of liquid unloaded by the unloading equipment does not match the total amount of liquid unloaded in the unloading request can be sent to a designated terminal device. The designated terminal device can be the terminal device corresponding to the relevant operator or manager, or the terminal device corresponding to the unloading equipment management platform. This embodiment does not impose any restrictions on this.
[0073] In some feasible embodiments, an alarm message indicating a mismatch between the total amount of liquid unloaded by the unloading equipment and the total amount of liquid unloaded in the unloading request is sent to a designated terminal device. The designated terminal device then manages the unloading equipment based on this alarm message. Furthermore, the designated terminal device updates the management information of the unloading equipment according to the alarm message and updates the alarm message in the corresponding database, facilitating management personnel to query the status of the unloading equipment and achieving data-driven management of the unloading process.
[0074] In this embodiment, by sending an alarm message to a designated terminal device when the total amount of liquid unloaded by the unloading equipment does not match the total amount of liquid unloaded in the unloading request, situations such as over-unloading or under-unloading by the unloading equipment can be prevented.
[0075] Furthermore, based on the above embodiments, please refer to... Figure 6 In one exemplary embodiment provided in this application, the specific implementation process of generating the unloading start command may further include steps S610 and S620, which are described in detail below:
[0076] Step S610: Obtain the current unloading status information of the unloading equipment;
[0077] Step S620: If the unloading equipment is detected to meet the preset unloading conditions based on the unloading condition information, an unloading start command is generated.
[0078] Specifically, after a liquid unloading request is sent via the unloading equipment—that is, when the location information of the unloading equipment matches the location information of the requested unloading area based on the unloading request—the system acquires the current unloading status information of the unloading equipment. This unloading status information includes whether the liquefied gas transport vehicle has arrived at the designated unloading location, whether the instruments on the liquefied gas transport vehicle are functioning properly, whether the flow meter of the unloading equipment is functioning properly, and whether the pipelines of the liquefied gas transport vehicle are functioning properly. The system also checks whether the environment at the parking location of the liquefied gas transport vehicle meets the preset unloading conditions. If it is determined that the current unloading status information of the unloading equipment meets the preset unloading conditions, a corresponding unloading start command is generated.
[0079] In this embodiment, by obtaining the current unloading status information of the unloading equipment before generating the unloading start command, and generating the unloading start command when the unloading status information of the unloading equipment meets the preset unloading conditions, the safety hazards caused by unloading when the current unloading status information does not meet the unloading conditions can be effectively avoided.
[0080] Furthermore, based on the above embodiments, please refer to... Figure 7 In one exemplary embodiment provided in this application, the above-described unloading control method further includes steps S710 to S730, which are described in detail below:
[0081] Step S710: Obtain the identification information of the unloading equipment, the identification information of the unloading area, and the total unloading volume contained in the unloading request.
[0082] Specifically, the unloading request sent by the driver or relevant operator of the liquefied gas transport vehicle through a triggering method that can distinguish identity information such as fingerprint, password, or user account includes the identification information of the unloading equipment to be unloaded. This identification information may include the license plate number of the unloading equipment, the identification identifier of the on-board terminal of the unloading equipment, or other identifying information used to characterize the unloading equipment. Furthermore, the unloading area and total unloading volume corresponding to this unloading request can also be obtained from the unloading request. For example, by parsing and combining the unloading request sent with the fingerprint information of the driver of the liquefied gas transport vehicle, the license plate number of the unloading equipment, the driver's fingerprint information, the identification information of the unloading area corresponding to the unloading order (e.g., a gas station), and the total unloading volume of the unloading order can be obtained from the unloading request.
[0083] In addition, in some feasible implementations, the above-mentioned unloading control method further includes comparing whether the driver's fingerprint information is consistent with the fingerprint information pre-stored in the unloading equipment. If the driver's fingerprint information is inconsistent with the fingerprint information pre-stored in the unloading equipment, an alarm message is generated and sent to a designated terminal device.
[0084] Step S720: Generate a liquid unloading order based on the identification information of the unloading equipment, the identification information of the unloading area, and the total unloading volume;
[0085] Step S730: Store unloading orders; wherein, unloading orders are used to manage unloading.
[0086] Specifically, a corresponding unloading order is generated based on the identification information of the unloading equipment, the description of the unloading area, and the total unloading volume in the unloading request sent by the unloading equipment. For example, the unloading order might include "Unloading equipment LPG-00X unloads XXX liters at XXX- gas station." The generated unloading order is stored to facilitate management by control personnel. Unloading control includes binding the unloading equipment to the identity information of the corresponding operator, the total transport volume of the unloading equipment, the setting of the unloading area for the unloading equipment, and alarm information generated during the unloading process.
[0087] In this embodiment, by parsing the unloading request sent by the unloading equipment, the identification information of the unloading equipment, the identification information of the unloading area, and the total unloading volume are obtained, and an unloading order is generated and stored based on this. This can effectively control the unloading process and perform digital management of the unloading, thus facilitating the unloading management work.
[0088] Furthermore, based on the above embodiments, please refer to... Figure 8 If the location information of the unloading equipment and the location information of the requested unloading area are detected to match based on the unloading request, the specific implementation process of generating the unloading start command may further include steps S810 to S840, which are described in detail below:
[0089] Step S810: Determine whether the location information of the requested unloading area can be found;
[0090] In step S820, if the location information of the requested unloading area cannot be found, a long-range wireless communication connection is established between the requested unloading area and the unloading equipment.
[0091] First, it's important to clarify that long-range wireless communication can utilize LoRa technology, a radio frequency IC suitable for the Internet of Things (IoT). Its design philosophy emphasizes low power consumption, long range, low cost, simple networking, and easy expansion. In general communication, communication distance is directly proportional to power consumption; the longer the transmission distance, the higher the power consumption. However, LoRa achieves long-range, low-power communication with high penetration. LoRa is based on spread spectrum hopping technology, resulting in significantly higher frequency offset and fault tolerance compared to similar ICs, along with higher sensitivity. It's a physical layer or wireless modulation used to establish long-range communication links. Many traditional wireless systems use Frequency Shift Keying (FSK) modulation as the physical layer because it's a very effective modulation for achieving low power consumption. LoRa is based on linear frequency modulation spread spectrum modulation, maintaining the same low-power characteristics as FSK modulation but significantly increasing communication distance. LoRa technology itself boasts extremely high receiver sensitivity (RSSI) and a very strong signal-to-noise ratio (SNR). Furthermore, it uses frequency hopping technology, employing pseudo-random code sequences for frequency shift keying, causing the carrier frequency to continuously hop and spread the spectrum, preventing fixed-frequency interference.
[0092] Specifically, by searching for the location information of the requested unloading area in the unloading order, if the location information of the requested unloading area cannot be obtained, a long-range wireless communication connection is established between the unloading equipment and the unloading request area through LoRa self-organizing network technology, and the location information of the unloading request area obtained through LoRa self-organizing network technology is further obtained.
[0093] Step S830: Based on long-range wireless communication technology, detect whether the location information of the unloading equipment and the location information of the requested unloading area match;
[0094] Step S840: If the location information of the unloading device and the location information of the requested unloading area are detected to match based on the unloading request, an unloading start command is generated.
[0095] Specifically, following the above embodiments, when the location information of the requested unloading area cannot be obtained, a long-range wireless communication connection is established between the unloading equipment and the requested unloading area, and the location information of the requested unloading area is obtained through long-range wireless communication technology. For example, after the long-range wireless communication connection between the unloading equipment and the requested unloading area is successfully established, an indicator indicating successful communication with the requested unloading area will appear on the terminal of the unloading equipment, thus allowing direct acquisition of the location information of the requested unloading area. Then, it is determined whether the location information of the unloading equipment matches the location information of the requested unloading area. If the location information of the unloading equipment matches the location information of the requested unloading area, an unloading start command is generated. This prevents the unloading equipment from failing to unload when the information is incompatible.
[0096] In this embodiment, when the location information of the requested unloading area cannot be obtained, a long-range wireless communication connection is established between the requested unloading area and the unloading equipment. This connection uses long-range wireless communication technology to check whether the location information of the requested unloading area matches the location information of the unloading equipment. If they match, an unloading start command is generated. Establishing communication between the location information of the requested unloading area and the unloading equipment using long-range wireless technology is simple and easy to implement, and can effectively prevent situations where the unloading equipment misses or steals unloading.
[0097] Figure 9 This is a simplified flowchart illustrating the unloading control of a liquid unloading device in an exemplary application scenario. In the scenario shown in Figure 9, the driver or operator of the liquid unloading device triggers an unloading request using methods such as fingerprints or user accounts, and sends this request to the control server. Upon receiving the unloading request, the control server determines whether the location information of the unloading device matches the location information of the requested unloading area. If they do not match, an alarm signal is issued; if they match, a corresponding unloading order is created. The control server sends a permission signal to the unloading device, prompting the driver or operator to check the environmental and operational information of the unloading device. Once both environmental and operational information meet the unloading conditions, a start unloading signal is sent to the control server. The control server then checks again whether the location information of the unloading device matches the location information of the requested unloading area. If they match, a unloading signal is sent to the unloading device, causing it to activate the unloader and begin unloading. The flow meter of the unloading equipment measures the unloading data in real time and feeds the unloading data back to the control server. The control server compares the unloading data with the total unloading volume corresponding to the unloading request. If they match, the control server sends an unloading stop command to the unloading equipment.
[0098] In some feasible embodiments, when the control server detects an anomaly during the unloading process, such as location mismatch, operator request to pause unloading, or unloading data mismatch, it generates an unloading stop command and sends it to the unloading equipment. After the unloading equipment stops unloading, it uploads its corresponding unloading data to the management platform. This platform not only stores the unloading data for each unloading device but also pre-binds the identity information of each unloading device and its corresponding driver or operator, as well as alarm information generated by the unloading device. This facilitates digital management of the unloading process by unloading managers and optimizes the unloading process.
