Description

Technical Field

[0001] This application relates to the field of liquid transportation technology, specifically to a method, apparatus, equipment, and storage medium for obtaining the surplus or deficit of transported liquids. Background Technology

[0002] Petrochemical railway tank cars are railway vehicles specifically designed for transporting petrochemical products in liquid or gaseous form, including crude oil, refined products, and chemicals. These tank cars possess excellent sealing and explosion-proof properties to ensure no leaks or other safety accidents occur during transportation. However, the measurement and monitoring of petrochemical products transported to their destinations still rely on traditional manual methods, leading to several problems. First, external environmental factors such as weather and temperature can easily cause errors in the measurement of liquid level, density, and temperature, potentially resulting in inaccurate results. Second, depth measuring tapes often exhibit a "climbing" phenomenon, where the measuring length slowly increases due to its own weight or external factors, affecting the accuracy of depth measurements. Furthermore, manually recording tank car information requires repeated data entry, which is time-consuming and prone to errors, thus affecting the integrity and accuracy of the data. The surplus or deficit of liquids transported by petrochemical railway tank cars during transportation is calculated based on data measured and monitored using traditional manual methods; the aforementioned problems can lead to significant deviations in calculating the surplus or deficit of liquids during transportation.

[0003] Therefore, how to reduce the calculation deviation of the profit or loss of the transported liquid during the transportation process is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0046] To facilitate understanding of the technical solutions provided in the embodiments of this application, the background technology involved in the embodiments of this application will be described below.

[0047] Petrochemical railway tank cars are railway vehicles specifically designed for transporting petrochemical products. These tank cars are typically designed to safely transport chemical products in liquid or gaseous forms, such as crude oil, refined petroleum products, and chemicals. Their structure incorporates sealing and explosion-proof features to ensure that leaks or other safety issues do not occur during transport.

[0048] Currently, the measurement and monitoring of petrochemical products transported by rail tank cars to their destination still relies on primitive manual methods, which have several problems. First, measurements of liquid level, density, and temperature are easily affected by external environmental factors such as weather and temperature, potentially leading to inaccurate results. Second, depth measuring tapes often exhibit a "climbing" phenomenon, where the measuring length slowly increases due to their own weight or external factors, affecting the accuracy of depth measurements. Furthermore, manually recording tank car information requires repeated entry, which is not only time-consuming but also prone to errors, affecting the integrity and accuracy of the data. The surplus or deficit of liquids transported by petrochemical rail tank cars during transportation is calculated based on data measured and monitored using traditional manual methods; the aforementioned problems can lead to significant deviations in calculating the surplus or deficit of liquids during transportation.

[0049] To address this issue, this application provides a method, apparatus, device, and storage medium for obtaining the surplus or deficit of transported liquids. First, the initial volume and a first liquid identifier of each target liquid are obtained. Then, the state parameters of the transport vehicle at the destination are obtained through a state parameter measurement device, the final mass of the target liquid is calculated, and a matching transport vehicle is determined. Subsequently, based on the initial volume of the target liquid corresponding to the first liquid identifier and the final mass of the matching vehicle, the surplus or deficit of each target liquid is calculated. This achieves real-time monitoring and recording of the liquid state, provides a data foundation for accurately calculating the surplus or deficit, and ensures that each target liquid mass corresponds to a specific vehicle, avoiding information confusion and erroneous summaries.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0051] See Figure 1 The figure is a flowchart of a method for obtaining the surplus or deficit of transported liquids according to an embodiment of this application. Figure 1 As shown, the method for obtaining the surplus or deficit of transported liquid may include steps S101-S105:

[0052] S101: Obtain the original amount and first liquid identifier of each target liquid.

[0053] To determine the surplus or deficit of the transported target liquids, the liquid surplus / deficit acquisition system first obtains the original volume of each target liquid and its corresponding first liquid identifier, which is obtained through the liquid transport plan. There is a one-to-one correspondence between the first liquid identifier and the original volume of each target liquid, ensuring that each liquid and its quantity can be clearly identified and recorded.

[0054] This ensures accurate tracking and management of the quantity and identity of each liquid throughout the entire liquid transportation process, effectively preventing liquid exchange or confusion, ensuring the safe transportation and correct delivery of the target liquid, and providing an accurate basis for subsequent liquid status monitoring and metering.

[0055] It should be noted that a liquid transport plan is a document or form that records information related to the transport of liquids. A liquid transport plan typically includes the following information: vehicle number (the number of the target vehicle for the target liquid), vehicle type (the type of target vehicle), marked load capacity (the rated load capacity of the target vehicle), identification number (the identification number on the target vehicle), product name (the name of the target liquid being transported), departure station (the point of origin of transport), destination station (the point of arrival), tank number (the number of the liquid loading tank on the target vehicle), storage time (the time the target liquid arrives at the point of origin of transport), storage date (the date the target liquid arrives at the point of origin of transport), storage location number (the number of the location where the target liquid is stored), track number (the track number on which the target vehicle is parked), seal number (the identification number of the sealed liquid), and initial quantity (the initial quantity of liquid). This information helps track and manage various details of the liquid during transport.

[0056] S102: Obtain the state parameters of the target liquid transported by each transport vehicle at the destination through state parameter measurement equipment.

[0057] The system acquires the state parameters of the target liquid transported by each transport vehicle at its destination using state parameter measurement devices. These parameters include the liquid's density, temperature, and level. These parameters are crucial for liquid transport management. Liquid density directly reflects its mass, temperature affects its volume and flowability, and the level indicates the amount of liquid stored and management requirements. By acquiring these state parameters in real time, the system ensures the accuracy of the quality and quantity of liquid transported each time it arrives at its destination.

[0058] It should be noted that state parameter measuring equipment refers to equipment used to measure and monitor various physical and chemical state parameters. These parameters may include temperature, pressure, flow rate, liquid level, humidity, concentration, vibration, etc.

[0059] S103: Calculate the final mass of the target liquid based on the state parameters of the target liquid at the destination.

[0060] Calculating the final mass of a target liquid at its destination involves measuring and analyzing parameters such as the liquid's density, temperature, and level to deduce the total mass. First, measuring the liquid's density yields the mass per unit volume. Then, combining this with the liquid's volume and level information, the total mass can be calculated. Furthermore, considering the effect of temperature on density, this factor must be taken into account to ensure accuracy. By comprehensively considering the liquid's density, temperature, and level, the final mass of the target liquid at its destination can be calculated more precisely.

[0061] The reason for calculating the final mass of a target liquid based on its state parameters at the destination is that these parameters directly affect the liquid's mass. The liquid's density tells us the mass contained per unit volume, while the liquid level provides the total volume. By combining these two parameters, the overall liquid mass can be determined. Additionally, temperature affects the liquid's density, so the impact of temperature changes on the liquid mass calculation must be considered. Calculating the final mass based on the target liquid's state parameters at the destination ensures the accuracy and reliability of the results, helps manage the profit and loss during liquid transportation, and provides important data analysis and decision-making support.

[0062] S104: Determine the transport vehicle that matches the first liquid identifier based on the first liquid identifier and the second liquid identifier.

[0063] Determining the transport vehicle matching the first liquid identifier is done by comparing the first liquid identifier and the second liquid identifier. Typically, the first liquid identifier is a unique identifier recorded in the liquid transport plan, used to mark a specific target liquid. The second liquid identifier is a specific identifier marked on the transport vehicle, corresponding to the first liquid identifier. When it is necessary to determine the transport vehicle corresponding to a specific target liquid, the matching second liquid identifier is searched based on the first liquid identifier to identify the correct transport vehicle.

[0064] Matching the first and second liquid identifiers to determine the corresponding transport vehicle ensures that each transport vehicle is accurately associated with the correct target liquid and related information. The first liquid identifier, as a unique symbol for the target liquid, helps identify and track the transportation process of each liquid. The second liquid identifier, directly affixed to the transport vehicle, establishes a clear association between a specific target liquid and a specific transport vehicle. Ensuring the matching of the first and second liquid identifiers avoids confusion and errors, ensuring that each target liquid is accurately assigned to the corresponding transport vehicle, improving the accuracy and reliability of data management. Therefore, determining the matching transport vehicle based on the first and second liquid identifiers helps ensure the smooth operation of the liquid transportation process and the clear and accurate recording of information.

[0065] In one possible implementation, the first liquid identifier includes the vehicle number of the target vehicle transporting the target liquid, the liquid name of the target liquid, and the seal number of the target liquid; the second liquid identifier includes the vehicle number of the transport vehicle, the liquid name of the target liquid transported by the transport vehicle, and the seal number of the target liquid transported by the transport vehicle.

[0066] See Figure 2 , Figure 2 The flowchart of a method for determining a transport vehicle matching a first liquid identifier is provided in an embodiment of this application. Accordingly, determining the transport vehicle matching the first liquid identifier based on the first liquid identifier and the second liquid identifier can be specifically implemented through steps A1-A3:

[0067] A1: Match the vehicle number of the target vehicle identified by the first liquid identifier with the vehicle number of the transport vehicle identified by the second liquid identifier; match the liquid name of the target liquid identified by the first liquid identifier with the liquid name of the target liquid transported by the transport vehicle identified by the second liquid identifier; match the seal number of the target liquid identified by the first liquid identifier with the seal number of the target liquid transported by the transport vehicle identified by the second liquid identifier.

[0068] To progressively match the different parameters in the first and second liquid identifiers and ensure their correlation, the following steps are taken: First, the vehicle number of the target vehicle in the first liquid identifier is matched with the vehicle number of the transport vehicle in the second liquid identifier. This helps determine the specific transport vehicle to which the target liquid belongs. Second, the liquid name of the target liquid in the first liquid identifier is matched with the liquid name of the target liquid transported by the transport vehicle in the second liquid identifier, confirming the correct correspondence between liquid types. Finally, the seal number of the target liquid in the first liquid identifier is matched with the seal number of the target liquid transported by the transport vehicle in the second liquid identifier, ensuring the correct matching of liquid safety sealing information.

[0069] By progressively matching parameters such as vehicle number, liquid name, and seal number, accurate matching of information between the first and second liquid identifiers can be ensured, thereby clarifying the association between the target liquid and the corresponding transport vehicle. This systematic matching process helps improve the accuracy and reliability of data management, avoids problems caused by information confusion or errors, and ensures that each target liquid can be correctly assigned to the appropriate transport vehicle.

[0070] A2: If the vehicle number, the liquid name, and the seal number all match, then the first liquid identifier and the second liquid identifier are determined to match.

[0071] When the vehicle number, liquid name, and seal number all match, i.e., all matching conditions are met, the first liquid identifier is confirmed to match the second liquid identifier. This means that the vehicle number of the target vehicle matches the vehicle number of the transport vehicle, the liquid name of the target liquid matches the liquid name of the target liquid transported by the transport vehicle, and the seal number of the target liquid matches the seal number of the target liquid transported by the transport vehicle.

[0072] Ensuring the matching of these three key parameters is crucial during liquid transportation. Only when all this information matches perfectly can the correct association of the target liquid with the appropriate transport vehicle be guaranteed. This rigorous matching mechanism helps avoid any potential confusion or errors, improving data accuracy and reliability. Therefore, when all key parameters are perfectly matched, the matching relationship between the first liquid identifier and the second liquid identifier can be confirmed, indicating that the target liquid has been accurately assigned to the corresponding transport vehicle, thus providing necessary assurance and supervision for the entire liquid transportation process.

[0073] A3: Based on the second liquid identifier that matches the first liquid identifier and the transport vehicle indicated by the second liquid identifier, determine the transport vehicle that matches the first liquid identifier.

[0074] Once it is confirmed that the first liquid identifier has successfully matched a specific second liquid identifier, the transport vehicle that matches the first liquid identifier will be determined based on the second liquid identifier and the transport vehicle indicated by the second liquid identifier.

[0075] In other words, the specific transport vehicle associated with the first liquid identifier can be directly identified through the matched second liquid identifier. The second liquid identifier provides detailed information about the liquid transport, including the liquid name, vehicle number, and seal number. Based on this information, the specific vehicle transporting the liquid can be tracked, thereby ensuring the proper management and monitoring of the target liquid's transport process.

[0076] S105: Calculate the profit or loss corresponding to the original amount of the target liquid corresponding to the first liquid identifier and the final mass of the target liquid transported by the matching transport vehicle.

[0077] Based on the initial quantity of the target liquid corresponding to the first liquid identifier and the final mass of the target liquid transported by the matched transport vehicle (i.e., the quantity after the transport is completed), the profit or loss corresponding to the initial quantity of each target liquid can be calculated.

[0078] Profit or loss refers to the actual loss or increase in the amount of the target liquid, calculated by comparing the initial volume with the final mass. If the final mass is higher than the initial volume, it indicates a profit; if the final mass is lower than the initial volume, it indicates a loss.

[0079] By comparing the initial quantity and final mass of each target liquid, the corresponding profit or loss can be calculated, and the potential losses or gains during liquid transportation can be further analyzed.

[0080] In one possible implementation, the method further includes:

[0081] A profit and loss statement is constructed based on each of the second liquid identifiers, the initial volume of each target liquid, the final mass of the target liquid transported by each transport vehicle, and the profit or loss corresponding to the initial volume of each target liquid.

[0082] A profit and loss statement can be constructed based on each secondary liquid identifier, the initial quantity of each target liquid, the final mass of the target liquid transported by each transport vehicle, and the profit or loss corresponding to the initial quantity of each target liquid. This statement will contain detailed information, listing the initial quantity, final mass, and profit or loss for each target liquid, helping to track and analyze the profit and loss situation during liquid transportation. Through this table, managers can gain a clearer understanding of the transportation effectiveness of each liquid batch, assess potential economic risks or profits, and make corresponding decisions to optimize liquid logistics management.

[0083] In one possible implementation, the method further includes:

[0084] The measurement time of each state parameter is obtained by the state parameter measuring device. Then, based on the state parameters and the final mass calculated based on the state parameters, the measurement time is marked with the profit or loss corresponding to the original amount of each target liquid. The state parameters have a one-to-one correspondence with the final mass and the profit or loss.

[0085] After measuring the measurement time of each state parameter using state parameter measuring equipment, the measurement time is labeled with the profit / loss corresponding to the original volume of each target liquid based on these parameters and the calculated final mass. In this process, there is a one-to-one correspondence between each state parameter and the final mass and profit / loss. This means that the measurement time of each state parameter can accurately record the associated final mass and profit / loss information, thereby ensuring data integrity and accuracy. By linking measurement time with state parameters, final mass, and profit / loss, a clear timeline can be established, helping to track, analyze, and review key information in the liquid transportation process, providing important support for effective management and monitoring.

[0086] Optionally, the measurement time for each profit or loss can also be included in the profit and loss statement.

[0087] In one possible implementation, the method further includes:

[0088] The profit and loss statement is verified. If the verification is successful, the profit and loss statement is uploaded to the target system according to the protocol requirements of the target system.

[0089] After verifying the profit and loss statement and confirming its accuracy, it will be uploaded to the target system according to the target system's protocol requirements. This operation ensures data accuracy and completeness, meeting the standards and requirements of the target system. By uploading the profit and loss statement, enterprises can effectively integrate and manage liquid transportation-related data, enabling monitoring and analysis of economic gains and losses, thereby providing a reliable basis for decision-making.

[0090] As described in S101-S105, this application acquires state parameters such as liquid density, liquid temperature, and liquid level of each transport vehicle at its destination using a state parameter measuring device, thus achieving real-time monitoring and recording of the liquid state. First, the initial volume and first liquid identifier of each target liquid can be obtained, and the state parameters of the target liquid transported by each transport vehicle at its destination can be acquired using the state parameter measuring device. Then, the final mass of the target liquid is calculated based on the state parameters at its destination, and the transport vehicle matching the first liquid identifier is determined based on the first liquid identifier and the second liquid identifier marked on the transport vehicle. Next, the surplus or deficit corresponding to the initial volume of each target liquid is calculated based on the initial volume of the target liquid corresponding to the first liquid identifier and the final mass of the target liquid transported by the matching transport vehicle. There is a one-to-one correspondence between the final mass of the target liquid and the transport vehicle. This one-to-one correspondence ensures that the mass calculation of each target liquid can be clearly attributed to the corresponding vehicle, avoiding information confusion and erroneous data aggregation.

[0091] See Figure 3 , Figure 3 This is a schematic diagram of a device for obtaining the surplus or deficit of transported liquids, provided as an embodiment of this application. Figure 3 As shown, the device for obtaining the surplus or deficit of the transported liquid includes:

Then, a second acquisition unit 302 acquires the state parameters of the target liquids transported by each transport vehicle at their destination using a state parameter measuring device. A first calculation unit 303 calculates the final mass of the target liquid based on the state parameters at the destination. Next, a first determination unit 304 determines the transport vehicle matching the first liquid identifier based on the first liquid identifier and a second liquid identifier marked on the transport vehicle. This allows the second calculation unit 305 to calculate the profit or loss corresponding to the initial volume of each target liquid based on the initial volume of the target liquid corresponding to the first liquid identifier and the final mass of the target liquid transported by the matching transport vehicle. This application utilizes a state parameter measuring device to monitor and record the liquid density, temperature, and level of each transport vehicle at the destination in real time, reflecting the state changes of the target liquid during transportation and providing an accurate data basis for profit or loss calculation. The final mass is calculated based on the target liquid state parameters, and a one-to-one correspondence with the matched vehicle is ensured. This ensures that the mass calculation of each target liquid is clearly attributed to a specific vehicle, avoiding information confusion and erroneous data aggregation.
