Description

Technical Field

[0001] The present invention relates to the technical field of warehousing measurement weighing, and in particular, to a weighing method and system for collaborative verification of a platform scale and a hanging scale for warehousing measurement. Background Art

[0002] Currently, in the operation system of the logistics warehousing industry, accurately measuring the weight of goods occupies a core position in many key business processes. For inventory management, accurate weight data is an important cornerstone for determining the quantity of goods, reasonably planning storage space, and evaluating inventory value. At the same time, in the transportation cost accounting link, the weight of goods is a key parameter directly determining freight calculation, transportation resource allocation, and logistics cost control.

[0003] However, traditional means of weighing goods, such as the common platform scale weighing method, expose significant limitations. Its main manifestations are that the sensors built into the platform scale are easily affected by the irregularity of the external environment temperature and long-term use, resulting in performance attenuation. As a result, the measurement of the platform scale is extremely likely to have numerical errors deviating from the true value, and it is difficult to meet the strict requirements of modern refined operations. Especially for high-value goods, even a small measurement error may still accumulate and cause huge economic losses in large-scale logistics warehousing operations.

[0004] At the same time, platform scale sensors usually adopt a multi-point layout to meet the weighing needs of goods with different sizes and weight distributions. However, this multi-point layout also introduces new problems, that is, it is difficult to accurately judge the attenuation degree of each point sensor. Since the load sizes borne by sensors at different points are different during actual use, and the working environmental conditions may also vary significantly, their attenuation processes are not synchronized and the degrees are different. In the current clear lack of effective detection means, it has become extremely difficult to accurately judge that the sensors at specific points have undergone excessive attenuation and need to be replaced in a timely manner.

[0005] In summary, there is an urgent need for a new technical solution to overcome the limitations of existing traditional goods weighing methods, so as to achieve high-precision, high-reliability, and easy-to-maintain goods weight measurement, thereby meeting the strict requirements for goods weighing in industries such as logistics and warehousing in the modern business environment. Summary of the Invention

[0006] Therefore, the present invention provides a weighing method and system for collaborative verification of a platform scale and a hanging scale for warehousing measurement to solve the technical problems in the prior art that the numerical accuracy and reliability of platform scale weighing are not high, and it is difficult to accurately judge that the sensors at specific points of the platform scale multi-point sensors have undergone excessive attenuation.

[0007] To achieve the above object, the present invention provides the following technical solutions: A weighing method for verifying the coordination of a floor scale and a crane scale for warehouse measurement comprises the following steps: Construct a system for collaborative weighing and accuracy verification of floor scales and crane scales; According to the collaborative weighing and its accuracy verification system, the individual weight values ​​of the goods weighed by the floor scale and the crane scale are obtained respectively, and the two sets of weight values ​​are compared to determine whether there is a weighing error between the floor scale and the crane scale; When it is determined that there is a weighing error, continue to use the coordinated weighing and accuracy verification system to make the crane scale and the goods be placed on the scale synchronously, and obtain the combined weighing value of the crane scale and the goods based on the scale; Compare the weight of the individual goods measured by the floor scale with the sum of the standard weight of the crane scale and the combined weight of the crane scale and the goods to further determine whether there is a weighing error in the floor scale and / or crane scale; Verify the levelness of the weighing surface for scales with weighing errors; Continue to adjust the weight distribution of the crane scale corresponding to the distributed weighing points of the floor scale based on the collaborative weighing and its accuracy verification system, and further verify the monitoring accuracy of each distributed weighing point of the floor scale based on the crane scale.

[0008] On the basis of the above technical solution, the present invention is further described as follows: As a further embodiment of the present invention, The construction of the coordinated weighing system of the floor scale and the crane scale and its accuracy verification system specifically includes: A floor scale component structure, a switchable hanging scale support frame structure correspondingly supported on the floor scale component structure or its base surface, and a hanging scale component structure arranged on the hanging scale support frame structure are respectively arranged; The structure of the floor scale assembly includes a floor scale platform, a strain weighing sensor and a sensor positioning cylinder seat; there are four groups of strain weighing sensors and sensor positioning cylinder seats respectively, and the four groups of strain weighing sensors are respectively and one by one built-in at the four corner ends of the floor scale platform, and the four groups of sensor positioning cylinder seats are respectively fixed on the top surface of the floor scale platform, and the built-in limiting channels of the four groups of sensor positioning cylinder seats are respectively and one by one arranged with the four groups of strain weighing sensors, so as to limit the four supporting points of the hanging scale support frame structure through the four groups of sensor positioning cylinder seats, and further make the four supporting points of the hanging scale support frame structure correspond to the four groups of strain weighing sensors to obtain weighing values ​​respectively; There are two groups of crane scale support frame structures, each of which includes a support frame body, a positioning pin seat, a lifting hydraulic cylinder, a lifting positioning cylinder seat and a horizontal sensor; each support frame body has two elevated support rods, and the bottom end of each elevated support rod is fixedly connected with two parallel groups of positioning pin seats; Four groups of lifting hydraulic cylinders are provided, and the four groups of lifting hydraulic cylinders are respectively fixed on the base surface positions on the sides of the four corner ends of the floor scale platform, and the kinetic energy output ends of the four groups of lifting hydraulic cylinders are transmission-fixedly connected to the lifting positioning cylinder seats, and the four groups of lifting positioning cylinder seats and the four groups of sensing positioning cylinder seats are arranged in parallel in a one-to-one correspondence; the two groups of positioning pin seats at the bottom end of each elevated support rod are respectively and one-to-one correspondingly inserted and limitedly supported on the lifting positioning cylinder seats and the sensing positioning cylinder seats arranged in parallel, and when the lifting hydraulic cylinder is in the initial low position state, the supporting height of the lifting positioning cylinder seat for the positioning pin seat is lower than the supporting height of the sensing positioning cylinder seat for the positioning pin seat; There are four groups of level sensors, which are fixedly connected to the bottom ends of the four elevated support rods one by one to monitor the supporting level of the support frame body corresponding to the weighing platform of the scale; The structure of the crane scale assembly includes a hoisting beam frame, an electric lifting push-pull rod, a translation drive assembly, a weighing sling and a strain tension sensor; the tops of both ends of the hoisting beam frame are symmetrically assembled and connected to the two sets of support frame bodies through two sets of electric lifting push-pull rods; the base of the translation drive assembly is fixedly arranged at the bottom end of the hoisting beam frame, and the linear kinetic energy output end of the translation drive assembly is connected to the weighing sling transmission; The weighing sling has a center of gravity corresponding to the translation drive assembly. Strain tension sensors are also connected between the two sets of electric lifting push-pull rods and the two sets of support frame bodies. When the weighing sling is at the center of gravity, the center of gravity of the crane scale assembly structure is located at the center position, the monitoring tension of the two sets of strain tension sensors is equal, and the weight distribution of the two sets of support frame bodies corresponding to the four elevated support rods is equal.

[0009] As a further embodiment of the present invention, According to the collaborative weighing and accuracy verification system, the individual weight values ​​of the goods weighed by the floor scale and the crane scale are obtained respectively, and the two sets of weight values ​​are compared to determine whether there is a weighing error between the floor scale and the crane scale, specifically including: The lifting hydraulic cylinders in the crane scale support frame structure synchronously output kinetic energy to drive the lifting positioning cylinder seat to rise, so that each lifting positioning cylinder seat correspondingly lifts the positioning pin seat and the support frame body until the positioning pin seat releases the weighing pressure on the strain weighing sensor in the floor scale platform. At this time, the crane scale support frame structure and the crane scale assembly structure are supported on the foundation surface of the side of the floor scale platform; By weighing the goods on the scale platform separately, the individual weight value of the scale is obtained. 1 ; The electric lifting push-pull rod of the crane scale assembly structure cooperates with the translation drive assembly to drive the weighing sling to lift the goods, and the weighing sling is weighed separately to obtain the weight value of the goods on the sling a. 2 ; Compare the individual cargo weight values ​​of the scale based on a specific error threshold range a 1 Weight of cargo with sling alone a2 : The individual weight value a of the weighbridge 1 and the individual weight value a of the lifting device 2 are equal within a specific error threshold range, i.e., a 1 = a 2 at this time, then take the individual weight value a 1 or a 2 as the standard weight value; When the individual weight value a of the weighbridge 1 and the individual weight value a of the lifting device 2 have a comparison value difference exceeding the error threshold range, i.e., a 1 ≠ a 2 at this time, then it is determined that there is a weighing error in the weighbridge platform and / or the weighing lifting device.

[0010] As a further solution of the present invention, when it is determined that there is a weighing error, continue according to the collaborative weighing and its accuracy verification system, make the hanging scale and the goods synchronously carried on the weighbridge, and based on the combined weighing value of the hanging scale and the goods weighed by the weighbridge, specifically including: Drive the lifting positioning cylinder seat to descend synchronously by the kinetic energy output of each group of lifting hydraulic cylinders in the hanging scale support structure. At this time, the positioning pin seat and the support main body descend synchronously with the lifting positioning cylinder seat. The positioning pin seat first lands on the weighbridge platform based on the sensing positioning cylinder seat and generates a weighing pressure on the strain weighing sensor in the weighbridge platform. Continue to drive the lifting positioning cylinder seat to descend until the lifting positioning cylinder seat releases the support for the positioning pin seat and the support main body. At this time, part of the hanging scale support structure and the hanging scale component structure are synchronously carried on the weighbridge platform with the goods; Part of the hanging scale support structure is the other part of the overall hanging scale support structure that does not include the lifting hydraulic cylinder and the lifting positioning cylinder seat carried on the base surface; Continue to conduct a combined weighing of the part of the hanging scale support structure, the hanging scale component structure and the goods carried by the weighbridge platform, and the calculation formula for obtaining the combined weighing value c is as follows: c = a 1 + b (1) In the formula, b is the known standard weight value of the body of the part of the hanging scale support structure and the hanging scale component structure, and a 1 is the individual weight value of the weighbridge weighed by the weighbridge platform.

[0011] As a further solution of the present invention, Compare the sum of the individual weight value weighed by the weighbridge and the standard weight value of the hanging scale body with the combined weighing value of the hanging scale and the goods, and further determine whether there is a weighing error in the weighbridge and / or the hanging scale, specifically including: Suppose a parameter k is set as the weighing deviation coefficient of the weighbridge, then the individual cargo weight value a weighed by the weighbridge platform 1 plus the known body standard weight value b of part of the hanging scale support structure and the hanging scale component structure is k×a 1 +b. The combined weighing value of part of the hanging scale support structure, the hanging scale component structure and the goods is k×(a 1 +b). Compare and verify the weighing deviation coefficient k of the weighbridge. The specific comparison process is as follows: When k×a 1 +b = k×(a 1 +b), then b = k×b, and the weighing deviation coefficient k = 1. At this time, it is proved that there is no weighing error in the weighbridge platform within the specific error threshold range. By reverse deduction, it is obtained that there is a weighing error in the weighing sling. Therefore, take the individual cargo weight value a 1 of the weighbridge as the standard cargo weight value; When k×a 1 +b ≠ k×(a 1 +b), then b ≠ k×b, and the weighing deviation coefficient k ≠ 1. At this time, it is proved that there is a weighing error in the weighbridge platform exceeding the specific error threshold range; Directly replace the weighing sling of the reserve standard group and hoist it again to obtain the individual cargo weight value a 3 of the sling. When a 3 =a 2 , then there is no weighing error in the initial weighing sling within the specific error threshold range. Otherwise, there is a weighing error. Take the individual cargo weight value a 3 of the sling as the standard cargo weight value.

[0012] As a further solution of the present invention, verify the surface levelness of the weighbridge for the weighbridge with weighing error, which specifically includes: Obtain the levelness signal in real time through the level sensors respectively installed at the bottom ends of the four groups of height support rods in the hanging scale support structure to jointly monitor the overall levelness of the hanging scale support structure, and deduce the levelness of the weighbridge platform surface based on the overall levelness of the hanging scale support structure; When the surface levelness of the weighbridge platform does not meet the standard, adjust the horizontal state of the weighbridge platform.

[0013] As a further solution of the present invention, continue to adjust the weight distribution of the hanging scale corresponding to the distributed weighing points of the weighbridge according to the collaborative weighing and its accuracy verification system, and further verify the monitoring accuracy of each distributed weighing point of the weighbridge based on the hanging scale, which specifically includes: Control and adjust the lifting and telescopic amounts of the two groups of electric lifting push-pull rods in the hanging scale component structure to be equal, so that the lifting beam frame and the weighing sling are kept in a horizontal state; Continue to control the translation drive component to adjust the horizontal position of the weighing sling to the center of gravity point, and monitor the tension values received by the two groups of strain tension sensors in real time. When the difference between the two tension values exceeds the error threshold range, continue to control the weighing sling to translate and fine-tune from the center of gravity point until the two tension values are equal within the error threshold range. At this time, the weight distribution of the weighing scale component structure corresponding to the two support frame bodies is the same, and at the same time, the weight distribution of the two support frame bodies corresponding to the four strain weighing sensors of the weighing platform is the same; Further, respectively and one-to-one monitor the distributed weights d of the four height support rods in the weighing scale support structure through the four strain weighing sensors of the weighing platform, and use the known standard weight value b of the body of the partial weighing scale support structure and the weighing scale component structure as a reference standard, and thus respectively compare and verify whether there is excessive attenuation in the weighing performance of the four strain weighing sensors of the weighing platform. That's all.

[0028] As Figures 1 to 4 shown, an embodiment of the present invention provides a collaborative verification weighing method for a weighbridge and a hanging scale for warehousing metrology, which can effectively overcome the limitations of traditional goods weighing methods, realize high-precision, high-reliability and easy-to-maintain goods weight measurement, so as to meet the strict requirements of the logistics warehousing industry for goods weighing. At the same time, it solves the problem that it is difficult to accurately judge the specific point of excessive attenuation of sensors at multiple points of the weighbridge in the prior art, and improves the overall functional practicality. The specific steps are as follows: S1: Construct a collaborative weighing system for the weighbridge and the hanging scale and its accuracy verification system; The specific process is as follows: A floor scale assembly structure 1, a hanging scale support frame structure 2 switchably supported on the floor scale assembly structure 1 or its base surface, and a hanging scale assembly structure 3 arranged on the hanging scale support frame structure 2 are respectively provided; More specifically, the floor scale assembly structure 1 includes a floor scale platform 11, a strain weighing sensor 12 and a sensor positioning cylinder seat 13; wherein, the strain weighing sensor 12 and the sensor positioning cylinder seat 13 are respectively provided with four groups, and the four groups of strain weighing sensors 12 are respectively and one by one correspondingly built-in at the four corner ends of the floor scale platform 11, and the four groups of sensor positioning cylinder seats 13 are respectively fixedly arranged on the top surface of the floor scale platform 11, and the built-in limiting channels of the four groups of sensor positioning cylinder seats 13 are respectively and one by one correspondingly arranged with the four groups of strain weighing sensors 12, so as to limit the four supporting points of the hanging scale support frame structure 2 through the four groups of sensor positioning cylinder seats 13, and further make the four supporting points of the hanging scale support frame structure 2 correspond to the four groups of strain weighing sensors 12 to obtain weighing values ​​respectively; There are two groups of scale support frame structures 2, and each group of scale support frame structures 2 includes a support frame body 21, a positioning pin seat 22, a lifting hydraulic cylinder 23, a lifting positioning cylinder seat 24 and a horizontal sensor 25; wherein, each group of support frame body 21 has two elevated support rods, and the bottom end of each elevated support rod is fixedly connected with two parallel groups of positioning pin seats 22; there are four groups of lifting hydraulic cylinders 23, and the four groups of lifting hydraulic cylinders 23 are respectively fixed to the base surface positions on the sides of the four corner ends of the floor scale platform 11, and the kinetic energy output ends of the four groups of lifting hydraulic cylinders 23 are transmission-fixedly connected with the lifting positioning cylinder seats 24, and the four groups of lifting positioning cylinder seats 24 and the four groups of sensor positioning cylinder seats 13 are arranged in parallel in a one-to-one correspondence; the two groups of positioning pin seats 22 at the bottom end of each elevated support rod are respectively and one-to-one correspondingly inserted and limitedly supported on the lifting positioning cylinder seats 24 and the sensor positioning cylinder seats 13 arranged in parallel, When the lifting hydraulic cylinder 23 is in the initial low position, the supporting height of the lifting positioning cylinder seat 24 for the positioning pin seat 22 is lower than the supporting height of the sensing positioning cylinder seat 13 for the positioning pin seat 22; therefore, when the lifting hydraulic cylinder 23 outputs kinetic energy to drive the lifting positioning cylinder seat 24 to descend, the positioning pin seat 22 and the support frame body 21 can be supported to the floor scale platform 11 based on the first fall of the sensing positioning cylinder seat 13, and can release its supporting effect on the positioning pin seat 22 and the support frame body 21 when the lifting positioning cylinder seat 24 further descends, and at the same time, the lifting hydraulic cylinder 23 outputs kinetic energy to drive the lifting positioning cylinder seat 24 to lift the positioning pin seat 22 and the support frame body 21, and the overall rise of the support frame body 21 releases the weighing pressure on the floor scale platform 11, thereby completing the weighing of the goods alone or the weighing of the goods in combination with the crane scale through the floor scale platform 11; There are four groups of level sensors 25, which are fixedly connected to the bottom ends of the four elevated support rods one by one to monitor the supporting level of the support frame body 21 corresponding to the weighbridge platform 11; The structure of the hanging scale assembly 3 includes a hoisting crossbeam frame 31, an electric lifting push-pull rod 32, a translation drive assembly 33, a weighing sling 34, and a strain tension sensor 35. Among them, the top ends of both ends of the hoisting crossbeam frame 31 are respectively and symmetrically assembled and connected to two sets of support frame bodies 21 through two sets of electric lifting push-pull rods 32. The base part of the translation drive assembly 33 is fixed to the bottom end part of the hoisting crossbeam frame 31, and a transmission connection is provided between the linear kinetic energy output end of the translation drive assembly 33 and the weighing sling 34 to adapt to different cargo suspension points for sling position adjustment. The weighing sling 34 has a center of gravity corresponding to the translation drive assembly 33. A strain tension sensor 35 is also connected between the two sets of electric lifting push-pull rods 32 and the two sets of support frame bodies 21. When the weighing sling 34 is at the center of gravity, the center of gravity of the hanging scale assembly structure 3 is located at the central position, the monitoring tensions of the two sets of strain tension sensors 35 are equal, and the weight distributions of the support frame bodies 21 corresponding to the four height support rods are equal. S2: According to the collaborative weighing and its accuracy verification system, separately obtain the individual cargo weight values weighed by the platform scale and the hanging scale for the goods, and compare the two sets of cargo weight values to determine whether there is a weighing error between the platform scale and the hanging scale. The specific process is as follows: The kinetic energy is synchronously output by each lifting hydraulic cylinder 23 in the hanging scale support structure 2 to drive the lifting positioning cylinder seat 24 to rise, so that each lifting positioning cylinder seat 24 correspondingly jacks up the positioning pin seat 22 and the support frame body 21 until the positioning pin seat 22 releases the weighing pressure on the strain weighing sensor 12 in the platform scale weighing table 11. At this time, the hanging scale support structure 2 and the hanging scale assembly structure 3 are carried on the base surface of the side part of the platform scale weighing table 11. By weighing the goods carried on the platform scale weighing table 11 alone, the individual cargo weight value a of the platform scale is obtained. 1 ; The electric lifting push-pull rod 32 of the hanging scale assembly structure 3 and the translation drive assembly 33 cooperate to drive the weighing sling 34 to hoist the goods, and the individual cargo weight value a of the sling is obtained by weighing alone through the weighing sling 34. 2 ; Based on a specific error threshold range, compare the individual cargo weight value a of the platform scale 1 with the individual cargo weight value a of the sling 2 : When the individual cargo weight value a of the platform scale 1 is equal to the individual cargo weight value a of the sling 2 within a specific error threshold range, that is, a 1 =a 2 , then take the individual cargo weight value a 1 or a 2 as the standard cargo weight value. When the individual cargo weight value a of the platform scale 1 is not equal to the individual cargo weight value a of the sling 2The comparison numerical value difference exceeds the error threshold range, that is, a 1 ≠a 2 When this happens, it is determined that there is a weighing error in the weighbridge platform 11 and / or the weighing sling 34; S3: When it is determined that there is a weighing error, continue according to the collaborative weighing and its accuracy verification system, make the hanging scale and the goods synchronously bear on the weighbridge, and based on the combined weighing value of the hanging scale and the goods weighed by the weighbridge; The specific process is as follows: The kinetic energy is synchronously output by each lifting hydraulic cylinder 23 in the hanging scale support structure 2 to drive the lifting positioning cylinder seat 24 to descend. At this time, the positioning pin seat 22 and the support frame body 21 descend synchronously with the lifting positioning cylinder seat 24. The positioning pin seat 22 first lands and bears on the weighbridge platform 11 based on the sensing positioning cylinder seat 13, and generates a weighing pressure on the strain weighing sensor 12 in the weighbridge platform 11. Continue to drive the lifting positioning cylinder seat 24 to descend until the lifting positioning cylinder seat 24 releases the supporting effect on the positioning pin seat 22 and the support frame body 21. At this time, part of the hanging scale support structure 2 and the hanging scale component structure 3 are synchronously borne on the weighbridge platform 11 with the goods. Among them, part of the hanging scale support structure 2 is the other part of the overall hanging scale support structure 2 that does not include the lifting hydraulic cylinder 23 and the lifting positioning cylinder seat 24 borne on the base surface; Continue to jointly weigh the part of the hanging scale support structure 2 and the hanging scale component structure 3 and the goods borne by the weighbridge platform 11, and the calculation formula for obtaining the combined weighing value c is as follows: c = a 1 + b (1) In the formula, b is the known standard weight value of the body of part of the hanging scale support structure 2 and the hanging scale component structure 3, and a 1 is the weight value of the goods alone weighed by the weighbridge platform 11; S4: Compare the sum of the weight value of the goods alone weighed by the weighbridge and the standard weight value of the hanging scale body with the combined weighing value of the hanging scale and the goods, and further determine whether there is a weighing error in the weighbridge and / or the hanging scale; The specific process is as follows: Suppose a parameter k is the weighing deviation coefficient of the weighbridge. Then, the sum of the weight value a of the goods alone weighed by the weighbridge platform 11 1 and the known standard weight value b of part of the hanging scale support structure 2 and the hanging scale component structure 3 is k × a 1 + b, and the combined weighing value of part of the hanging scale support structure 2 and the hanging scale component structure 3 and the goods is k × (a 1 + b). Compare and verify the weighing deviation coefficient k of the weighbridge. The specific comparison process is as follows: When k × a 1 + b = k × (a 1+b), then b = k × b, and the weighing deviation coefficient k of the weighbridge = 1. At this time, it is proved that there is no weighing error in the weighbridge platform 11 within a specific error threshold range. By reverse deduction, it is obtained that there is a weighing error in the weighing sling 34. Therefore, the separate weight value a of the weighbridge is taken 1 as the standard weight value; When k × a 1 +b ≠ k × (a 1 +b), then b ≠ k × b, and the weighing deviation coefficient k of the weighbridge ≠ 1.

At this time, the crane scale support frame structure and the crane scale assembly structure are supported on the foundation surface of the side of the floor scale platform; By weighing the goods on the weighbridge platform separately, the separate weight value a1 of the weighbridge is obtained; The electric lifting push-pull rod of the crane scale assembly structure cooperates with the translation drive assembly to drive the weighing sling to lift the goods, and the weighing sling is weighed separately to obtain the weight value a2 of the goods of the sling alone; Compare the single cargo weight value a1 of the scale and the single cargo weight value a2 of the spreader based on a specific error threshold range: When the individual cargo weight value a1 of the scale and the individual cargo weight value a2 of the spreader remain equal within a specific error threshold, that is, when a1=a2, the individual cargo weight value a1 or a2 is taken as the standard cargo weight value; When the comparison value difference between the single cargo weight value a1 of the floor scale and the single cargo weight value a2 of the sling exceeds the error threshold range, that is, when a1≠a2, it is determined that there is a weighing error in the floor scale platform and / or the weighing sling.

At this time, the positioning pin seat and the support frame body are synchronously descended with the lifting positioning cylinder seat. The positioning pin seat is first carried to the scale platform based on the position of the sensor positioning cylinder seat, and generates weighing pressure for the strain weighing sensor in the scale platform, and continues to drive the lifting positioning cylinder seat to descend until the lifting positioning cylinder seat releases the supporting effect of the positioning pin seat and the support frame body. At this time, part of the crane scale support frame structure and the crane scale component structure are synchronously carried on the scale platform with the goods; Part of the crane scale support structure is the other part of the overall crane scale support structure excluding the lifting hydraulic cylinder and the lifting positioning cylinder seat supported on the foundation surface; Continue to use the floor scale to weigh the part of the crane scale support structure and the crane scale component structure and the goods carried by it, and the calculation formula for the combined weighing value c is as follows: c=a1+b (1) Wherein, b is the known standard weight value of the partial crane scale support structure and the crane scale component structure, and a1 is the weight value of the single cargo on the scale measured by the scale platform.

The sum of the single cargo weight value a1 weighed by the floor scale platform and the known body standard weight value b of the partial hanging scale support structure and the hanging scale component structure is k×a1+b. The combined weighing value of the partial hanging scale support structure and the hanging scale component structure and the cargo is k×(a1+b). The weighing deviation coefficient k of the floor scale is verified by comparison. The specific comparison process is as follows: When k×a1+b=k×(a1+b), then b=k×b, and the weighing deviation coefficient of the scale k=1. At this time, it is proved that the scale platform has no weighing error within the specific error threshold range. Inversely, it is deduced that the weighing sling has a weighing error. Therefore, the single cargo weight value a1 of the scale is taken as the standard cargo weight value; When k×a1+b≠k×(a1+b), then b≠k×b, and the weighing deviation coefficient of the scale k≠1. This proves that the weighing error of the scale platform exceeds the specific error threshold range. Directly replace the weighing slings of the prepared standard group and weigh the slings again to obtain the single cargo weight value a3 of the slings. When a3=a2, the initial weighing sling has no weighing error within the specific error threshold range, otherwise there is a weighing error. Take the single cargo weight value a3 of the sling as the standard cargo weight value.
