[0002] Tanker metering refers to the measurement and recording of quantities when a tanker is loading or unloading oil.

[0003] At present, the measurement of oil tankers mainly involves three parameters: oil density, temperature and liquid level. In the current measurement process, oil density and temperature are measured by portable electronic density meters, while the liquid levels of each tank of the oil tanker are completed by manual dipsticks.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0055] like Figure 1 As shown, it is a schematic diagram of the architecture of an anti-cheating and anti-tampering system for oil product metering calculation of an oil tanker provided in an embodiment of the present application. The metering system includes: a storage application 100 and a measuring instrument 200.

[0056] The storage application 100 is used to obtain the tanker information from the tanker measurement information when receiving the tanker measurement information; the tanker information includes the measurement sequence of the tanks, and the measurement data for each tank, and uses the preset tank capacity table to perform quality calculation on the measurement data of the tanks to obtain the oil quality of each tank, and store the oil quality of each tank in the database.

[0057] The cabin information includes the measurement order of the cabins, the ship name, the cabin number, and the oil product name (eg, crude oil).

[0058] The oil tanker measurement information is information of the oil tanker that needs to be measured.

[0059] It can be understood that when receiving the tanker measurement information, the storage application obtains the cabin information from the tanker measurement information and sends the cabin information to the measuring instrument, so that the measuring instrument measures the cabin.

[0060] Among them, the oil quality in the ship's hold usually refers to the quality status of the oil stored in the ship's cargo hold, which generally includes the physical properties (such as density, viscosity, flash point, etc.) and chemical properties (such as water content, sulfur content, freezing point, etc.) of the oil.

[0061] It can be understood that the quality of the measured data of the cabin is calculated using the preset cabin capacity table. Specifically, relevant information corresponding to the measured data of the cabin is obtained from the preset cabin capacity table; the oil quality of the cabin is calculated based on the relevant information and the measured data of the cabin.

[0062] It should be noted that, when the measurement data of each cabin is received, the storage application uses the preset cabin capacity table to perform quality calculation on the measurement data of the cabin to obtain the oil quality of each cabin.

[0063] The storage application 100 executes the measurement data of each hold, and uses the preset tank capacity table to perform quality calculation on the measurement data of the hold to obtain the oil quality of each hold. Specifically, it is used for: for the measurement data of each hold, obtaining the temperature, liquid level information and density of the hold from the measurement data of the hold; filtering out the volume corresponding to the temperature and liquid level information of the hold from the preset tank capacity table; calculating the product between the density and the volume corresponding to the temperature and liquid level information of the hold to obtain the oil quality of each hold.

[0064] The temperature, liquid level information and density of the cabin are obtained from the measurement data of the cabin, so that the oil quality of the cabin can be calculated based on the temperature, liquid level information and density of the cabin.

[0065] The preset tank capacity table stores the correspondence between the temperature and liquid level information and the volume in advance, so the volume corresponding to the temperature and liquid level information of the cabin can be screened out from the preset tank capacity table. Specifically, the specific form of the preset tank capacity table is shown in Table 1.

[0066] Table 1

[0067] Cabin Dimensions (m) <![CDATA[Volume (m 3 )]]> Liquid level information (m) Temperature (℃) 1 10x5x3 150 2.5 40 2 8x4x2.5 80 2.0 45 3 12x6x4 288 3.0 50

[0068] It should be noted that the content of Table 1 above is only for illustration.

[0069] The specific expression of the oil quality in each tank is obtained by calculating the product of the density and the volume corresponding to the temperature and liquid level information of the tank, as shown in formula (1).

[0070] Density × volume = oil mass in the tank (1)

[0071] The storage application 100 is also used to: for each cabin, obtain the expected oil quality of the cabin from the database; compare the oil quality of the cabin with the expected oil quality to obtain the current profit and loss of the oil; and display the current profit and loss of the oil through a preset interface.

[0072] In order to ensure that the quality of oil products can be accurately controlled and monitored during cargo loading and transportation, the expected oil product quality of the cabin is obtained from the database so as to determine whether the current oil product quality of the cabin meets expectations based on the expected oil product quality of the cabin.

[0073] It can be understood that the oil quality in the cabin is compared with the expected oil quality to obtain the current oil profit and loss situation. Specifically, the oil quality in the cabin is compared with the expected oil quality to obtain a comparison result (i.e., the difference between the oil quality in the cabin and the expected oil quality); based on the comparison result, the current oil profit and loss situation is calculated; if the oil quality in the cabin is consistent with the expected oil quality, the profit and loss is zero; if the oil quality in the cabin is inconsistent with the expected oil quality, the profit and loss situation can be determined by calculating the difference between the oil quality in the cabin and the expected oil quality.

[0074] It should be noted that by displaying the current profit and loss situation of oil products, ship operators can understand the current quality status of oil products in real time and take necessary measures to adjust cargo management and transportation strategies in a timely manner to ensure safe transportation of cargo and optimal operational efficiency.

[0075] The storage application 100 is also used to: when receiving permission setting information, obtain the permission level of each account information from the permission setting information; according to the permission level of each account information, assign each account information the permission to view the oil quality in the cabin; when receiving a viewing request, obtain the oil quality in the cabin corresponding to the viewing permission of the account information in the viewing request from the database.

[0076] Among them, account information includes account name and account password.

[0077] It is understandable that each account information corresponds to a different permission level, and different permission levels correspond to different viewing permissions. Therefore, it is necessary to obtain the permission level of all account information in order to subsequently set the viewing permissions of each account.

[0078] It should be noted that, according to the authority level of each account information, each account information is assigned the authority to view the oil quality in the cabin. Specifically, the account information with the highest authority level should have full authority to view all oil quality in the cabin, including real-time data and historical records, while the account information with low authority levels can only view the oil quality in the cabin that it is responsible for.

[0079] When an input viewing request is received, the account information in the viewing request is first obtained, and then the oil quality of the cabin corresponding to the viewing authority of the account information in the viewing request is obtained from the database.

[0080] It should be noted that if there is no viewing permission in the account information, an error message will be returned.

[0081] The measuring instrument 200 is used to measure each cabin in turn according to the measurement order of the cabins to obtain the measurement data of each cabin.

[0082] The measured data include but are not limited to: density, temperature, liquid level information (referring to the height or depth of the liquid (such as oil, water, chemicals, etc.) in the cabin relative to the bulkhead or other standard reference points).

[0083] Optionally, each cabin can be measured by a sensor in the measuring instrument to measure the density, temperature, and liquid level of each cabin, obtain the measurement data of each cabin, and send the measurement data of each cabin to the storage application.

[0084] It should be noted that the measuring instrument stores the measurement data of the cabin. Since the measurement data of the cabin stored by the measuring instrument cannot be modified or deleted, timely traceability and integrity of the data can be ensured.

[0085] Specifically, assuming that there are three cabins, namely the first cabin, the second cabin and the third cabin, the measurement order of the first cabin is the first measurement, the measurement order of the third cabin is the second measurement, and the measurement order of the third cabin is the third measurement. According to the measurement order of the cabins, the first cabin, the third cabin and the second cabin are measured in turn to obtain the measurement data of the first cabin, the measurement data of the second cabin and the measurement data of the third cabin.

[0086] The measuring instrument 200 measures each cabin in turn according to the measurement sequence of each cabin to obtain the measurement data of each cabin. It is specifically used for: obtaining the serial number of each cabin from the measurement sequence of the cabins; measuring each cabin in turn according to the sequence number from small to large to obtain the measurement data of each cabin.

[0087] It can be understood that each cabin is sorted in advance to obtain a measurement sequence of the cabins, and the measurement sequence of the cabins includes the serial number of each cabin. Therefore, the serial number of each cabin can be obtained from the measurement sequence of the cabins.

[0088] Optionally, each cabin may be measured in sequence according to the cabin number from large to small.

[0089] Specifically, assuming there are four cabins, namely the first cabin, the second cabin, the third cabin and the fourth cabin, the first cabin is numbered 3, the second cabin is numbered 2, the third cabin is numbered 1, and the fourth cabin is numbered 4. According to the order of the cabin numbers from small to large, the third cabin is measured first, then the second cabin, then the first cabin, and finally the fourth cabin, to obtain the measurement data of the four cabins.

[0090] In summary, in the process of measuring the cabins, the cabins are measured first, and then the oil quality of each cabin is calculated based on the measurement data of each cabin. From the beginning of measurement to the end of measurement, the whole process does not involve manual work, and the data in the measuring instrument cannot be modified or deleted, which prevents the measurement data from being tampered with.

[0091] like Figure 2 As shown, it is a flow chart of a method for preventing cheating and tampering of oil product measurement calculation of an oil tanker provided in an embodiment of the present application, which is applied to the measurement system of an oil tanker, and includes the following steps:

[0092] It should be noted that the measurement system of oil tankers includes measuring instruments and storage applications.

[0093] S201: When receiving the tanker measurement information, obtain the tanker information from the tanker measurement information.

[0094] S202: measuring each cabin in turn according to the measurement order of the cabins to obtain measurement data of each cabin.

[0095] Optionally, in another embodiment of the present application, the specific implementation of step S202 is as follows: Figure 3 As shown, the following steps are included:

[0096] S301: Obtain the serial number of each cabin from the measurement sequence of the cabins.

[0097] S302: measuring each cabin in order according to the cabin number from small to large, and obtaining measurement data of each cabin.

[0098] S203: For the measurement data of each cabin, the preset cabin capacity table is used to perform quality calculation on the measurement data of the cabin, to obtain the oil quality of each cabin, and the oil quality of each cabin is stored in the database.

[0099] Optionally, in another embodiment of the present application, the specific implementation of step S203 is as follows: Figure 4 As shown, the following steps are included:

[0100] S401: For the measurement data of each cabin, the temperature, liquid level information and density of the cabin are obtained from the measurement data of the cabin.

[0101] S402: Filter out the volume corresponding to the temperature and liquid level information of the cabin from the preset cabin capacity table.

[0102] S403: Calculate the product of the density and the volume corresponding to the temperature and liquid level information of the cabin to obtain the oil quality of each cabin.

[0103] Optionally, after step S203, in order to understand the situation of oil products in real time, the profit and loss situation of oil products can be displayed through a preset interface, and timely actions can be taken to manage the profit and loss according to the profit and loss situation of oil products. If losses are found, the transportation strategy or cost structure can be adjusted as soon as possible to minimize the losses. Therefore, another embodiment of the present application provides a method for displaying the profit and loss situation of oil products, such as Figure 5 As shown, the following steps are included:

[0104] S501: For each tank, the expected oil quality of the tank is obtained from the database.

[0105] S502: Compare the oil quality in the ship's cabin with the expected oil quality to obtain the current oil profit and loss situation.

[0106] S503: Display the current profit and loss situation of the oil product through a preset interface.

[0107] Optionally, after step S203, in order to ensure the security and privacy of data, the user or system can be restricted from accessing sensitive information and key functions by setting permission information. This helps prevent unauthorized personnel or systems from performing malicious operations or abusing permissions, thereby improving the security of the system. Therefore, another embodiment of the present application provides a method for viewing information, such as Figure 6 As shown, the following steps are included:

[0108] S601: When authority setting information is received, the authority level of each account information is obtained from the authority setting information.

[0109] S602: According to the authority level of each account information, the authority to view the oil quality in the cabin is allocated to each account information.

[0110] S603: When a viewing request is received, the oil quality of the tank corresponding to the viewing authority of the account information in the viewing request is obtained from the database.

[0111] Combination Figure 2 For the contents shown, see Figure 7 A schematic diagram of an anti-cheating and anti-tampering process for oil tanker oil product metering calculation is shown. When the storage application receives the oil tanker metering information, the oil tanker information (such as the tanker number, oil product name) is obtained from the oil tanker metering information, and the oil tanker information is sent to the measuring instrument. The measuring instrument measures the density, temperature and liquid level of the tanker's tank based on the oil tanker information, and sends the density, temperature and liquid level of the tank to the storage application; the storage application calculates the oil quality in the tank based on the density, temperature and liquid level, and displays the profit and loss situation based on the oil quality in the tank.

[0112] In summary, in the process of measuring the cabins, the cabins are measured first, and then the oil quality of each cabin is calculated based on the measurement data of each cabin. From the beginning of measurement to the end of measurement, the whole process does not involve manual work, and the data in the measuring instrument cannot be modified or deleted, which prevents the measurement data from being tampered with.
