These platforms usually include offshore engineering modules, underwater support structures, and single point mooring systems, etc.; the offshore engineering modules and structures such as jacket are called offshore engineering equipment structures; after these modules and jacket are built, it is necessary to accurately weigh them. The weighing process can accurately measure the total weight and the center of gravity position of the structure, which is crucial for ensuring the safe installation of offshore engineering equipment structures at sea and is also the basic data for offshore lifting operations.

[0004] Currently, when facing the weighing of ten-thousand-ton offshore engineering equipment, due to the different nodal reaction forces at each weighing point, using a single weighing point weighing measurement layout method results in an unclear number of weighing equipment to be arranged. Moreover, when weighing and measuring the ten-thousand-ton offshore engineering equipment structure, due to the complex weighing site environment and being affected by signal interference factors, the actual value cannot be obtained, resulting in a certain error in the finally calculated weight, thus causing difficulties in the subsequent transportation of ten-thousand-ton offshore engineering equipment. Summary of the Invention

If the matching is successful, then according to the voltage signal corresponding to the output at the current temperature and the corresponding zero-temperature drift voltage, calculate the output voltage after compensation of the weight sensor.

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0058] As Figure 1 shown, a weighing measurement method for offshore engineering equipment of the present invention includes the following steps:

[0059] S1. According to the modeling and simulation, obtain the weighing points of the offshore engineering equipment structure and the reaction forces at the corresponding points.

[0060] It should be noted that using modeling and simulation software, according to the actual structure and dimensions of the offshore engineering equipment, a three-dimensional model is established. The reaction force is the vertical downward force borne by each weighing point of the offshore engineering equipment under specific working conditions. Through simulation analysis, the weighing points of the offshore engineering equipment in the stressed state are determined, and in the simulation results, the reaction force data of each weighing point is extracted.

[0061] S2. According to the reaction forces at each weighing point and the actual bearing capacity of the weighing measurement device, calculate the number of weighing measurement devices pre-arranged at each weighing point respectively.

[0062] Among them, obtain the full-load bearing capacity of the weighing measurement device, set the reserve coefficient of the bearing capacity, and calculate the actual bearing capacity of the weighing measurement device. The expression is:

[0063] F s = T * A

[0064] Wherein, F s is the actual bearing capacity of the weighing measurement device, T is the full-load bearing capacity of the weighing measurement device, and A is the set reserve coefficient;

[0065] It should be noted that the reserve coefficient A is usually a number less than 1, which is used to ensure that the measurement device operates within a safe range and takes into account possible additional loads or uncertainties.

[0066] According to the reaction forces at each weighing point and the actual bearing capacity of the weighing measurement device, the number of weighing measurement devices pre-arranged at each weighing point is calculated respectively. The expression is:

[0067] N j = F j / F s

[0068] Wherein, N j is the number of weighing measurement devices pre-arranged at the j-th weighing point, F j is the reaction force corresponding to the j-th weighing point, and N j is an integer and is rounded up.

[0069] S3. Preset the layout adjustment strategy. According to the pre-arranged number of weighing measurement devices and the layout adjustment strategy, arrange the weighing measurement devices at the corresponding positions below the weighing points.

[0070] Step S3 includes the following sub-steps:

[0071] Obtain the pre-arranged number of weighing measurement devices corresponding to the weighing points and the planar shape of the corresponding weighing points;

[0072] According to the planar shape of the weighing points, construct the minimum enclosing body. The first enclosing body is tangent to the outermost endpoints on each side of the planar shape of the weighing points. Connect the two diagonal endpoints of the minimum enclosing body to obtain the intersection position of the two diagonals as the centroid position of the weighing points;

[0073] When N j = 1, arrange the weighing measurement device at the centroid position of the corresponding weighing point;

[0074] When N j = 2, obtain the longest straight line that extends from the intersection position of the two diagonals to the edges of the weighing points at both ends, and take the one-third position of the straight line as the layout point of the weighing measurement device;

[0075] When N jWhen it is >2, obtain the edge enclosing curve of the planar shape of the weighing point position, offset the edge enclosing curve towards the inside to obtain the offset enclosing curve, obtain the position from the centroid position of the corresponding weighing point position to the farthest point on the offset enclosing curve as the initial layout position, equally divide according to the length of the offset enclosing curve and the pre-arrangement quantity, and starting from the initial layout position, arrange the weighing measurement devices at each equal division point of the offset enclosing curve.

[0076] It should be noted that the minimum enclosing body is the minimum circumscribed rectangle. When N j >2, according to the actual shape and force distribution of the weighing point position, determine a suitable offset amount to generate the offset enclosing curve. This offset amount is greater than the length of the contact surface between the weight sensor and the weighing point position to ensure the stability of measurement; all the above placement methods satisfy that the weighing measurement devices evenly bear the force of the weighing point. Through the above steps, the measurement devices can be reasonably arranged according to the pre-arrangement quantity of the weighing measurement devices and the planar shape of the weighing point position, so as to meet the requirements of weighing measurement.

[0077] Such as Figure 3 As shown, in S4, the weighing measurement device includes a weight sensor and a temperature sensor. Compensate the data measured by the weight sensor based on the measurement data of the temperature sensor, and output the compensated weight of each weighing measurement device. Calculate the total weighing weight of the offshore equipment structure based on the compensated weight.

[0078] The weighing measurement device in this embodiment further includes a cushion plate, a hydraulic jack and a displacement sensor. Among them, the cushion plate is arranged on the ground, the hydraulic jack is fixed on the side of the cushion plate away from the ground. The cushion plate is used to keep the weighing measurement device horizontal. The weight sensor is arranged on the plunger plane of the hydraulic jack and abuts against the surface of the weighing point position of the offshore equipment structure for measuring the weight of the weighing point position. The displacement sensor is arranged on the side of the plunger of the hydraulic jack for measuring the height of the plunger of the jack pushed out, so as to keep the measurement heights of each weighing measurement device consistent.

[0079] It should be noted that the backing plate is set on the ground and serves as the support foundation for the entire weighing and measuring device. Its main function is to ensure that the weighing and measuring device remains horizontal during installation and use, thereby avoiding measurement errors caused by uneven ground. The hydraulic jack serves as the support structure for the weight sensor and the displacement sensor. The hydraulic jack supports and measures the weight of the offshore equipment structure through the up and down movement of its plunger. The weight sensor is set on the plunger plane of the hydraulic jack and is directly in contact with the surface of the weighing point of the offshore equipment structure. The main function of the weight sensor is to measure the weight of the weighing point and convert the measurement data into an electrical signal for transmission and processing. The displacement sensor is set on the side of the plunger of the hydraulic jack and is used to measure the height of the plunger of the jack. By measuring the height of the plunger, it can be ensured that each weighing and measuring device maintains a consistent measurement height during measurement, thereby further improving the measurement accuracy.

[0080] Before measurement, first adjust the height and levelness of the backing plate to ensure that the entire weighing and measuring device is horizontal. Then, adjust the plunger of the hydraulic jack to an appropriate initial position to ensure that the weight sensor and the displacement sensor can work properly. Next, place the weighing point of the offshore equipment structure on the weight sensor and support it through the plunger of the hydraulic jack. During the measurement process, the weight sensor will measure the weight of the weighing point in real time and convert the measurement data into an electrical signal for transmission and processing. At the same time, the displacement sensor will measure the height of the plunger of the hydraulic jack to ensure that the measurement heights of each weighing and measuring device are consistent. Finally, analyze and process the measurement data to obtain the accurate weight of the weighing point of the offshore equipment structure.

[0081] As Figure 4 shown, the weighing and measuring device in this embodiment further includes an A / D conversion and sampling unit, a signal amplification unit, and an MCU control unit. Among them, temperature sensors are set at each weighing point to measure the external temperature data during weighing; the input end of the A / D conversion and sampling unit is electrically connected to the output end of the temperature sensor to collect the voltage signal of the temperature sensor at the current temperature; the output end of the weight sensor is electrically connected to the input end of the signal amplification unit to amplify the signal collected by the weight sensor, and the output end of the signal amplification unit is electrically connected to the input end of the A / D conversion and sampling unit to collect the output voltage signal of the weight sensor amplified by the amplifier circuit; the input end of the MCU control unit is electrically connected to the output end of the A / D conversion and sampling unit to compensate the data measured by the weight sensor according to the currently measured temperature.

[0082] It should be noted that when weighing a 10,000-ton marine engineering equipment, temperature sensors are arranged beside the measuring points to measure the external temperature data in real time during weighing. The temperature data is crucial for the accuracy of weight measurement because temperature changes may affect the performance of the weighing sensor and the accuracy of the measurement results. The A / D conversion sampling unit is responsible for converting the analog signal into a digital signal for subsequent processing by the MCU control unit. Its input terminal is electrically connected to the output terminals of the temperature sensor and the signal amplification unit, and is used to collect the voltage signals of the temperature sensor and the weight sensor. The signal amplification unit is used to amplify the signals collected by the weight sensor to improve the signal strength and stability. Its input terminal is electrically connected to the output terminal of the weight sensor, and the output terminal is electrically connected to the input terminal of the A / D conversion sampling unit. The MCU control unit is the core controller of the entire weighing measurement device, responsible for processing the data from the A / D conversion sampling unit and performing compensation based on the temperature data. It can receive the digital signal output by the A / D conversion sampling unit and correct the measurement data of the weight sensor according to the preset algorithm to improve the measurement accuracy.

[0083] Step S4 includes the following sub-steps:

[0084] S41, construct a zero-temperature drift database, which stores the voltage signal values output at different temperatures and the corresponding zero-temperature drift voltages.

[0085] It should be noted that constructing a zero-temperature drift database is for subsequent temperature compensation. The zero-temperature drift database should contain multiple temperature points and their corresponding zero-temperature drift voltages. These values can be obtained through experimental measurements and stored in the database for subsequent use. The accuracy and integrity of the zero-temperature drift database are crucial for the effect of temperature compensation. Therefore, when constructing the database, it should be ensured that all possible temperature ranges are covered and the zero-temperature drift voltages at each temperature point are accurately measured.

[0086] S42, according to the A / D conversion sampling unit, collect the voltage output by the temperature sensor corresponding to the current temperature, and transmit the collected voltage output corresponding to the current temperature to the memory of the acquisition circuit for temporary storage.

[0087] S43, according to the A / D conversion sampling unit, collect the voltage output by the weight sensor amplified by the signal amplification unit, and transmit the collected voltage output by the weight sensor to the MCU control unit;

[0088] In S44, the MCU control unit matches the corresponding zero-temperature-drift voltage in the zero-temperature-drift database according to the voltage output by the temperature sensor at the current temperature. If the match is successful, the output voltage of the weight sensor after compensation is calculated based on the voltage signal output at the current temperature and the corresponding zero-temperature-drift voltage. The calculation formula is:

[0089] U e =U o -U c

[0090] In the formula, U e is the output voltage of the weight sensor after compensation, U o is the voltage output by the weight sensor, and U c is the zero-temperature-drift voltage corresponding to the voltage output at the current temperature;

[0091] The MCU control unit weighs and measures the compensated weight of the weighing measurement device according to the output after compensation of the weight sensor, and accumulates the compensated weights output by all weighing measurement devices to obtain the total weighing weight of the offshore equipment structure.

[0092] If the match is unsuccessful in step S44, two adjacent element values are found in the zero-temperature-drift database according to the voltage output by the temperature sensor at the current temperature, and the corresponding zero-temperature-drift voltages are obtained according to the two adjacent element values, and the zero-temperature-drift voltage corresponding to the voltage output by the temperature sensor at the current temperature is calculated and obtained. The formula is:

[0093]

[0094] In the formula, U t is the voltage output by the temperature sensor at the current temperature, U ti and U t(i+1) are respectively two adjacent element values found in the zero-temperature-drift database for the voltage output by the temperature sensor at the current temperature. U t is located between (U ti , U t(i+1) ); U ci is the zero-temperature-drift voltage corresponding to U ti , and U c(i+1) is the zero-temperature-drift voltage corresponding to U t(i+1) .

[0095] In this embodiment, through the zero-temperature-drift database and the temperature compensation algorithm, the influence of temperature change on the measurement result of the weight sensor can be effectively eliminated, so that the measurement device can provide accurate and stable weight data in different temperature environments, improving the accuracy and reliability of the measurement.

[0096] In addition, the measurement device can adapt to the measurement requirements in different temperature environments without frequent adjustment or calibration, thereby enhancing stability and reliability. Through the processing of the signal amplification unit and the MCU control unit, the influence of external noise and interference on the measurement results can be effectively reduced, the signal anti-interference ability can be improved, and the measurement accuracy and reliability can be improved.

[0097] As Figure 2 shown, specifically, the weighing points of the offshore equipment structure and the reaction forces at the corresponding points are obtained. There are 13 weighing points in this embodiment, and the reaction force data of each weighing point is shown in Table 1:

[0098] Table 1

[0099]

[0100] For the hydraulic jacks below the weighing points in this embodiment, when weighing a ten-thousand-ton offshore equipment, the hydraulic jacks and the load cells are combined in a stacked manner, where the load cells are placed above the hydraulic jacks, and the displacement sensors are installed at positions outside the plunger plane of the jacks. The combined quantity of the hydraulic jacks and the load cells arranged below each weighing point is calculated according to the nodal reaction forces of the ten-thousand-ton offshore equipment structure, and 42 sets of weighing measurement devices need to be arranged, as shown in Table 2:

[0101] Table 2

[0102]

[0103] Weigh the offshore equipment structure according to the arrangement of 42 sets of weighing measurement devices. Through the zero-point temperature drift database and the temperature compensation algorithm, eliminate the influence of temperature changes on the measurement results of the load cells, obtain the accurate weights of each measurement point, and thus obtain the accurate total weight of the offshore equipment structure.

[0104] The present invention also provides an offshore equipment weighing measurement system, which is implemented by using the above-mentioned offshore equipment weighing measurement method. The system includes:

[0105] An acquisition module, configured to obtain the weighing points of the offshore equipment structure and the reaction forces at the corresponding points according to the modeling and simulation;

[0107] An arrangement module, configured to preset an arrangement adjustment strategy, and arrange the weighing measurement devices at the corresponding positions below the weighing points according to the pre-arrangement quantity of the weighing measurement devices and the arrangement adjustment strategy;

[0108] The second calculation module, for a weighing measurement device including a weight sensor and a temperature sensor, compensates the data measured by the weight sensor based on the measurement data of the temperature sensor, outputs the compensated weight of each weighing measurement device, and calculates the total weighing weight of the offshore equipment structure based on the compensated weight.
