The terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the invention discloses a mixed material weighing method and mixed material equipment, which are beneficial to improving the accuracy of indoor positioning. The following detailed description is made with reference to the accompanying drawings.

Example one

Referring to fig. 1, fig. 1 is a schematic flow chart of a mixed material weighing method disclosed in the embodiment of the present invention. As shown in fig. 1, the mixed material weighing method may include the following steps.

101. After the weight value information and the material type information of the total material are obtained, detecting whether a plurality of measured materials exist in the total material by the material mixing equipment according to the material type information; if yes, executing the step 102 to the step 108, otherwise, ending the process.

In the embodiment of the present invention, the mixing device may include a mixing multi-head combination scale, a combination mixer, and other mixing devices, and the embodiment of the present invention is not limited in this embodiment, the weight value information at least includes information of a weight value of each material in the total material, and the weight value of each measured material is within a preset weight range.

As an optional implementation manner, in the embodiment of the present invention, the mixing device may have a mixing mode switching function, that is, when the mixing device needs to change the current mixing mode, the mixing device may be in communication connection with the terminal device through communication manners such as serial communication, WIFI communication, or bluetooth communication, so as to control the mixing device to perform mixing operations through the terminal device and set relevant operations such as target weight parameters of various different materials.

102. The material mixing equipment distributes each several measured materials into each corresponding several weighing hoppers according to the material type information.

As an optional implementation manner, in the embodiment of the present invention, after the several metered materials are distributed into each corresponding several weighing hoppers, the mixing device may detect whether there is a large particle material whose weight value exceeds a preset weight range value in the several metered materials, and if so, the mixing device may discharge the large particle material whose weight value exceeds the preset weight range value.

103. The material mixing equipment evenly distributes the number of the rest weighing hoppers according to the material type information to obtain a rest material weighing hopper area; wherein the number of the weighing hoppers in each residual material weighing hopper area is consistent.

As an alternative, in the embodiment of the present invention, when the number of remaining weighing hoppers is not sufficient for the average division, that is, the number of weighing hoppers in each remaining material weighing hopper area cannot be consistent, each weighing hopper in excess can be randomly allocated to the remaining material weighing hopper area.

For example, if the total number of weighing hoppers is 36, the number of weighing materials is 2, and the number of remaining materials is 4 (material a, material B, material C, and material D, respectively), then the number of weighing hoppers will take 2 out of the number of weighing hoppers as the number of weighing hoppers, and the number of remaining weighing hoppers will be 34, and after the number of remaining weighing hoppers is evenly distributed into 4 materials according to the material type information, i.e., there will be 8 weighing hoppers in each remaining material weighing hopper area, but there will be 2 weighing hoppers in the number of remaining weighing hoppers that cannot be evenly distributed, at this time, the remaining 2 weighing hoppers can be randomly distributed into any remaining material weighing hopper area, if the remaining 2 weighing hoppers are randomly distributed into the remaining material weighing hopper area of material a and the remaining material weighing hopper area of material B, then there are 9 weighing hoppers in the present A material surplus material weighing hopper district and the B material surplus material weighing hopper district respectively, and there are 8 weighing hoppers in C material surplus material weighing hopper district and the D material surplus material weighing hopper district respectively.

For another example, if the total number of weighing hoppers is 34, the number of measured materials is 2, and the number of remaining materials is 4 (material a, material B, material C, and material D, respectively), then the number of measured materials will take 2 weighing hoppers as the number of weighing hoppers, and the number of remaining weighing hoppers will be 32, and the number of remaining weighing hoppers can be evenly distributed into 4 materials according to the material type information, that is, each remaining material weighing hopper area will have 8 weighing hoppers.

104. The mixing equipment distributes the residual materials into each corresponding residual material weighing hopper area according to the material type information; wherein, the residual material weighing hopper area comprises a first target material weighing hopper area and a first composition material weighing hopper area.

As an alternative implementation manner, in the embodiment of the present invention, the remaining material weighing hopper area may include a first target material weighing hopper area and a plurality of first composition material weighing hopper areas, for example, if the remaining material may include 4 materials (respectively, material a, material B, material C, and material D) according to the material type information, and the number of remaining weighing hoppers is already allocated into 4 remaining material weighing hopper areas according to the material type information, material a may be allocated into the material remaining material weighing hopper area a, material B may be allocated into the material remaining material weighing hopper area B, material C may be allocated into the material remaining material weighing hopper area C, and material D may be allocated into the material remaining material weighing hopper area D, wherein the material remaining material weighing hopper area a may be set as the first target material weighing hopper area, the material B residual material weighing hopper area, the material C residual material weighing hopper area and the material D residual material weighing hopper area are the first composition material weighing hopper area.

105. And the mixing equipment performs combination operation on the first materials in each first composition material weighing hopper area according to the weight value information of each material to obtain a first optimal combined weight value corresponding to each first composition material weighing hopper area.

As an alternative implementation manner, in the embodiment of the present invention, the mixing device may obtain the weight value of the material in the weighing hopper in each first composition material weighing hopper area, perform a combination operation on the material in the weighing hopper in each first composition material weighing hopper area to obtain an optimal value in the weighing hopper, and finally obtain the first optimal combination weight value from the plurality of weighing hoppers in each first composition material weighing hopper area.

For example, if each first composition material weighing hopper area includes 8 weighing hoppers, 4 kinds of remaining materials (i.e., a material a, a material B, a material C, and a material D) are respectively allocated to 8 weighing hoppers in each corresponding first composition material weighing hopper area according to material type information, and the material B is set to be placed, after the remaining material weighing hopper areas of the material C and the material D are the first composition material weighing hopper areas, the mixing device can perform combination operation on each weighing hopper according to the preset weight value of each current first composition material weighing hopper area, so that each weighing hopper can obtain the combined weight value closest to the preset weight value, and finally, the combined weight value closest to the preset weight value can be selected from the 8 weighing hoppers as the first optimal combined weight value.

For another example, if the preset weight value of the material B is 10g, the preset weight value of the material C is 20g, the preset weight value of the material D is 30g, and the combined weight values closest to 10g among the 8 weighing hoppers in the first combined material B weighing hopper area are 9.8 g, 9.86 g, 9.9g, 9.92 g, 9.93 g, 9.96 g, 9.97 g and 9.99g, respectively, it can be seen that the combined weight value closest to 10g among the 8 weighing hoppers in the first combined material B weighing hopper area is 9.99g, so that 9.99g is the first optimal combined weight value in the first combined material B weighing hopper area, and similarly, the material C and the material D are operated in the same way to obtain the first optimal combined weight value in the corresponding first combined material weighing hopper area.

106. The mixing equipment calculates a first target combined weight value in a first target material weighing hopper area according to the first optimal combined weight value and the weight value of the counting metering materials; the first target combined weight value is obtained by subtracting each first optimal combined weight value and the designated weight value of each counting material from the first weighing target value.

As an alternative implementation manner, in the embodiment of the present invention, if 4 kinds of materials (respectively, material a, material B, material C, and material D) and 2 kinds of metering materials (respectively, material e with a weight value of 0.76g and material f with a weight value of 0.95 g) are currently provided, the mixing device can obtain 3 first composition material weighing hopper areas (respectively, first combination material weighing hopper area B, first combination material weighing hopper area C, and first combination material weighing hopper area D) and 1 first target material (material a) weighing hopper area according to the material type information, if the first weighing target value is set to be 80g and 3 pieces of material e and material f need to be charged, and the first optimal combination weight value in the first combination material weighing hopper area B is 9.99g according to the combination operation, the first optimal combination weight value in the first combination material weighing hopper area C is 19.95g, after the first optimal combined weight value in the material weighing hopper area of the first combined D is 29.9g, a first target combined weight value of 14.08g can be obtained, wherein the calculation mode of the first target combined weight value is as follows: 80g-3 x 0.76g-4 x 0.95g-9.99g-19.95g-29.9g =14.08 g.

107. And the material mixing equipment performs combined operation on the second material in the first target material weighing hopper area according to the first target combined weight value and the information of each material weight value so as to obtain a second optimal combined weight value closest to the first target combined weight value.

As an optional implementation manner, in the embodiment of the present invention, the mixing device may obtain the weight value of the material in the weighing hopper in the first target material weighing hopper area, perform a combination operation on the material in the weighing hopper in the first target material weighing hopper area to obtain an optimal value in the weighing hopper, and finally obtain the first optimal combined weight value from the plurality of weighing hoppers in the first target material weighing hopper area.

For example, if 8 weighing hoppers are provided in the first target material weighing hopper area, the first target combined weight value is 14.08g, and the optimal values obtained in each weighing hopper in the first target material weighing hopper area are 13.9g, 13.95 g, 13.99 g, 14.01 g, 14.05 g, 14.07 g, 14.1 g and 14.11 g, respectively, it can be seen that the combined weight value closest to the first target combined weight value of 14.08g among the 8 weighing hoppers in the first target material weighing hopper area is 14.07 g, and thus 14.07 g is the second optimal combined weight value in the first target material weighing hopper area.

108. And the material mixing equipment respectively controls each first composition material weighing hopper area, each particle weighing hopper and the first target material weighing hopper area to execute discharging operation according to the first optimal combined weight value, the designated weight value and the second optimal combined weight value.

As an optional implementation manner, in the embodiment of the present invention, the mixing device may control each weighing hopper to discharge several weighing hoppers, and at the same time, control the weighing hopper in each first composition material weighing hopper area to obtain a first optimal combined weight value and control the weighing hopper in the first target material weighing hopper area to discharge a second optimal combined weight value.

Therefore, by implementing the mixed material weighing method described in fig. 1, the error value between the final blanking total weight value and the target blanking weight value can be effectively reduced, so that the weighing precision is improved, and the accurate mixed material weight value is favorably obtained.

In addition, compared with the combined metering mixed material weighing method in the prior art, the mixed material weighing method described in the figure 1 can minimize the error influence range and ensure the accuracy of the actual discharged weight.

In addition, the mixed material weighing method described in the figure 1 is implemented, and the arrangement of weighing and discharging of a plurality of metering materials is added, so that manual production is replaced by mechanical production, and the mixed material weighing accuracy and the working efficiency of the mixed material equipment are effectively improved.

In addition, by implementing the mixing weighing method described in fig. 1, the mixing device can discharge a plurality of measured materials exceeding a preset weight range value, so that the measured materials discharged according to the particles can be kept at a certain precision, the weighing precision is effectively guaranteed, and the accurate mixing weight value is favorably obtained.

Example two

Referring to fig. 2, fig. 2 is a schematic flow chart of another mixed material weighing method disclosed in the embodiment of the present invention. As shown in fig. 2, the mixed material weighing method may include the following steps.

201. After the weight value information and the material type information of the total material are obtained, detecting whether a plurality of measured materials exist in the total material by the material mixing equipment according to the material type information; if so, execute step 202 to step 210, otherwise execute step 212 to step 21.

202. The material mixing equipment distributes each several measured materials into each corresponding several weighing hoppers according to the material type information.

203. The material mixing equipment evenly distributes the number of the rest weighing hoppers according to the material type information to obtain a rest material weighing hopper area; wherein the number of the weighing hoppers in each residual material weighing hopper area is consistent.

204. The mixing equipment distributes the residual materials into each corresponding residual material weighing hopper area according to the material type information; wherein, the residual material weighing hopper area comprises a first target material weighing hopper area and a first composition material weighing hopper area.

205. The mixing device performs combined calculation on the weight value of the first material in each weighing hopper in the first composition material weighing hopper area to obtain N combined weight values.

206. And selecting a first combined weight value closest to the first material target weight value as a first optimal combined weight value from the N combined weight values by the material mixing equipment.

As an optional implementation manner, in the embodiment of the present invention, if it is set that the remaining material weighing hopper area currently containing 4 remaining materials (i.e., the material a, the material B, the material C, and the material D) is set as a first composition material weighing hopper area, 8 weighing hoppers may be disposed in each first composition material weighing hopper area, the mixing device may perform a combining operation on each weighing hopper according to a preset weight value of each current first composition material weighing hopper area, so that each weighing hopper can obtain a combined weight value closest to the preset weight value, and finally, the combined weight value closest to the preset weight value may be selected from the 8 weighing hoppers as a first optimal combined weight value.
