Description

Technical Field

[0001] The invention belongs to the technical field of data processing, and in particular relates to a method and system for automatically acquiring a balance weighing value. Background Art

[0002] As a key parameter, the weighing value of the balance plays a vital role in the calculation, evaluation and traceability of the test results of the weighed sample. In the laboratory testing of mineral products, it is often necessary to use an electronic balance to weigh a large number of mineral samples. For example, in the moisture detection of imported copper concentrate, multiple weighing work is required. Generally, a mineral sample is taken for every 500 tons and the mineral sample is individually tested for multiple moisture measurements. Taking a batch of 10,000 tons of copper concentrate as an example, 20 samples are required, and 2 samples are extracted from each mineral sample for moisture determination. A single moisture determination requires weighing and recording the mass of the sample pan, the mass of the sample pan and sample before drying, the mass of the sample pan and sample after drying, and at least one constant weight verification weighing, that is, the moisture determination of a single sample is weighed at least 4 times, and the whole batch needs to be weighed and recorded 160 times. In the traditional operation mode, the numerous weighing times bring great challenges and pressure to the inspector's manual recording. Each time the inspector records, he needs to repeatedly and carefully check whether the balance reading is consistent with the recorded value, which is time-consuming and labor-intensive, and it is also difficult to achieve later data traceability verification.

[0003] The prior art has disclosed a variety of automatic reading methods for balance weighing data. For example, the patent document with publication number CN106815428A uses genetic algorithms, particle swarm optimization algorithms, differential evolution algorithms, simulated plant growth algorithms, fruit fly algorithms and other intelligent optimization algorithms to optimize the independent variables of the balance component equation group to improve the quality of weighing data processing; the patent document with publication number CN115752666A uses a multi-strategy wolf pack algorithm to predict the dynamic weighing of tobacco leaves on an electronic balance through an ELM neural network with an improved wolf pack algorithm, thereby improving the problem that the ELM neural network is prone to fall into local optimality and improving the accuracy of dynamic weighing of tobacco leaves. The applicant has found out through searching that the existing automatic reading methods of balance data mostly rely on intelligent optimization algorithms. Intelligent optimization algorithms represented by the above-mentioned genetic algorithm, particle swarm optimization algorithm, differential evolution algorithm, simulated plant growth algorithm, fruit fly algorithm, wolf pack algorithm, etc., all have common problems such as slow convergence speed, many control variables, and complex algorithm termination criteria. When faced with heavy weighing tasks, intelligent optimization algorithms often consume a lot of time and it is difficult to quickly obtain weighing results. Therefore, how to strike a balance between the efficiency and accuracy of automatically obtaining balance weighing values ​​is a problem that needs to be considered. Summary of the invention

[0004] In order to solve the above-mentioned problems existing in the prior art, the present invention proposes a method and system for automatically acquiring balance weighing values, so as to solve the problems of slow convergence speed, many control variables and complex algorithm termination criteria when using intelligent optimization algorithms to obtain balance weighing data in the prior art, thereby taking into account the efficiency and accuracy of automatic acquisition of balance weighing value data.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a method for automatically obtaining weighing values ​​of a balance, the method comprising the steps of: S1: obtaining a group of weighing values ​​transmitted by a balance; S2: encoding the weighing values ​​transmitted by the balance obtained in S1; S3: calculating a generating polynomial of the weighing values ​​transmitted by the encoded balance; S4: judging whether there is an error byte based on the generating polynomial calculated in S3; if there is, executing S5, if not, executing S6; S5: re-reading another group of weighing values ​​transmitted by the balance, and executing S2; S6: decoding the weighing values ​​transmitted by the balance after encoding in S2, and transmitting them to a data reading module, so as to automatically obtain the weighing values ​​transmitted by the balance.

[0006] Furthermore, the basic form of the generator polynomial in S3 is: ; Where GP(x) represents the generating polynomial, x represents the unknown quantity of the polynomial, r represents the length of the redundant bits of information, gp1, gp r-1 、gp r-2 Represents a binary number.

[0007] Furthermore, in said S4, based on the generator polynomial calculated in step S3, it is determined whether there is an error byte, specifically: S41: based on the root of the generator polynomial calculated in step S3, the power sum function is calculated: ; Where k represents the number of consecutive powers, S k represents a power sum function with k consecutive powers, α represents a primitive element of the GF domain, j0…j v-1 Indicates the bit to be determined whether there is an error byte, v represents the bit number and v≤k / 2, where k / 2 represents the number of error bytes. are the roots of the generating polynomial; S42: constructing an error byte determination polynomial based on the power sum function, and determining whether an error byte exists according to the error byte determination polynomial.

[0008] Furthermore, in S42, an error byte determination polynomial is constructed based on the power sum function, specifically: ; Where EL(x) represents the error byte determination polynomial, σ1…σv Indicates the error byte determination polynomial coefficient.

[0009] Furthermore, the error byte determination polynomial coefficient is solved according to the following formula: ; Where m represents the odd number of the power sum function, m = 1, 3, 5, ..., S1 represents a power sum function with 1 consecutive power, S2 represents a power sum function with 2 consecutive powers, S m represents a power sum function with m consecutive powers.

[0010] Further, in S42, it is determined whether an error byte exists according to the error byte determination polynomial. Specifically, if the error byte determination polynomial is an indecomposable polynomial, or the root of the error byte determination polynomial does not belong to the set of roots of the generating polynomial, then it indicates that there is no error byte. If the error byte determination polynomial is a decomposable polynomial and the root of the error byte determination polynomial belongs to the set of roots of the generating polynomial, then it indicates that there is an error byte.

[0011] According to another aspect of the present invention, there is also provided a system for automatically acquiring a balance weighing value, comprising a balance weighing value reading module, an error byte judgment module and a data reading module, wherein the input end of the balance weighing value reading module is connected to the data output end of the electronic balance, the output end of the balance weighing value reading module is connected to the input end of the error byte judgment module, and the output end of the error byte judgment module is connected to the input end of the data reading module; the electronic balance is connected to the balance weighing value reading module via an RS232 serial port and an RS9 data line. The system is used to implement the aforementioned automatic acquisition method for balance weighing values.

[0012] Compared with the prior art, the beneficial technical effect of the present invention is that an error byte determination polynomial is constructed by using a power sum function calculated by a generating polynomial, and based on the decomposable characteristics of the error byte determination polynomial, it is determined whether an automatically acquired balance weighing value has an error byte, thereby avoiding the problems of slow convergence speed, many control variables, and complex algorithm termination criteria brought about by the intelligent optimization algorithm in the prior art, and taking into account the efficiency and accuracy of automatic acquisition of balance weighing value data.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0017] In conjunction with the instruction manual Figure 1 The present invention provides a method for automatically acquiring a balance weighing value, which specifically includes: Step S1: Acquire a set of weighing values ​​transmitted by the balance. After the interface mode of the balance is set to the data transmission mode and the setting is successful, the balance can continuously send data to the computer, and at this time, a set of weighing values ​​transmitted by the balance is acquired; the present invention adopts a METTLERTOLEDO PL6001E or ME4002E balance, both of which have an RS232 serial port, and the RS9 data line can be used to connect the balance to the computer. The reading of the balance weighing value data can be realized by writing program codes using appropriate programming languages ​​(Visual Basic, Visual C++, Delphi, Java) and related controls (MSComm, SPCOMM). Step S2: Encode the weighing value transmitted by the balance obtained in step S1. Step S3: Calculate the generating polynomial of the weighing value transmitted by the encoded balance; wherein the basic form of the generating polynomial is as follows: ; Where GP(x) represents the generating polynomial, x represents the unknown quantity of the polynomial, r represents the length of the redundant bits of information, gp1, gp r-1 、gp r-2 represents a binary code number, satisfying 2r≥mes+r+1, mes represents the information bit length. It can be understood that the above binary code number is a binary code of 0 or 1, and the binary code number can be 100110, for example.

[0018] Step S4: Based on the generator polynomial calculated in step S3, determine whether there is an error byte; if so, execute step S5; if not, execute step S6; the specific steps of determining whether there is an error byte are: Step S41: Based on the roots of the generator polynomial calculated in step S3, calculate the power sum function: ; Where k represents the number of consecutive powers, S k represents a power sum function with k consecutive powers, α represents a primitive element of the GF domain, j0…j v-1 Indicates the bit to be determined whether there is an error byte, v represents the bit number and v≤k / 2, where k / 2 represents the number of error bytes. are the roots of the generating polynomial; Step S42: constructing an error byte determination polynomial based on the power sum function, wherein the error byte determination polynomial is constructed in the following form: ; Where EL(x) represents the error byte determination polynomial, σ1…σ v Represents the error byte determination polynomial coefficient. The error byte determination polynomial coefficient is solved according to the following formula: ; Where m represents the odd number of the power sum function, m is an odd number, that is, m=1, 3, 5, etc., S1 represents a power sum function with 1 consecutive power, S2 represents a power sum function with 2 consecutive powers, S m represents a power sum function with m consecutive powers.

[0019] In step S42, it is determined whether there is an error byte based on the error byte determination polynomial. Specifically, if the error byte determination polynomial is an indecomposable polynomial, or the root of the error byte determination polynomial does not belong to the set of roots of the generating polynomial, it indicates that there is no error byte. If the error byte determination polynomial is a decomposable polynomial and the root of the error byte determination polynomial belongs to the set of roots of the generating polynomial, it indicates that there is an error byte. The above error byte may be caused by an abnormality in a storage unit or a data transmission channel in the computer. It should be noted that when there are error bytes in the transmitted balance weighing value data, the transmitted balance weighing value data is equivalent to a model in which a group of correct balance weighing value data and a group of noise balance weighing value data are superimposed. The error byte determination polynomial constructed only by the correct balance weighing value data in the GF field (finite field) can be decomposed, and the error byte determination polynomial can be expressed as the common multiple of the minimum polynomial of the roots of the generating polynomial. Therefore, the roots of the solved error byte determination polynomial must belong to the set of roots of the generating polynomial; and when there are error bytes, the equivalent noise data cannot be decomposed, or even if it can be decomposed, its corresponding roots do not belong to the set of roots of the generating polynomial. Therefore, by determining whether the error byte determination polynomial is decomposable and whether its roots belong to the set of roots of the generating polynomial, it is possible to determine whether there are error bytes in the transmitted balance weighing value data, without having to adopt the complex intelligent optimization algorithm in the prior art, thereby saving the time for detecting error bytes in the data and taking into account the efficiency and accuracy of automatic acquisition of balance weighing value data.

[0020] Step S5: re-read another set of weighing values ​​transmitted by the balance, and execute step S2; when there are erroneous bytes in the weighing value data of the balance, it is necessary to discard the set of data and re-read a new set of weighing values ​​transmitted by the balance to ensure the correctness of the data.

[0021] Step S6: Decode the weighing value transmitted by the balance after encoding in step S2, and use a decoding rule corresponding to the encoding rule to decode the weighing value data, such as CRC encoding and CRC decoding. Then transmit the decoded data to a data reading module to automatically obtain the weighing value transmitted by the balance.

[0022] As the instruction manual Figure 2As shown, the present invention also provides a system for automatically acquiring a balance weighing value, the system implements the method for automatically acquiring a balance weighing value as described above, the system for automatically acquiring a balance weighing value comprises a balance weighing value reading module, an error byte judgment module and a data reading module, the input end of the balance weighing value reading module is connected to the data output end of the electronic balance, the output end of the balance weighing value reading module is connected to the input end of the error byte judgment module, and the output end of the error byte judgment module is connected to the input end of the data reading module. In this embodiment, the balance weighing value reading module and the data reading module are implemented through a web page. The web page can control the connection and disconnection of the balance, the real-time display of the balance reading, the recording of the balance reading in the table, the dynamic increase and decrease of the record table, and the naming and export of the recorded data according to regulations; specifically, when the balance weighing value reading module determines that the balance serial port is successfully connected, it calls the readable of the port object in the web page program to obtain the data stream. At this time, the readable lock state is true, and the "reader = port.readable.getReader()" method is used to create a reader reader and use "{ value, done} = awaitreader.read()" to obtain binary data, and the conversion between binary data and strings is completed by connecting the serial port read stream and the textDecoder write stream through the data channel. The data reading module is used to trigger the "record" event of the page when the balance reading is stable, execute the custom "save(this)" method, and the this parameter carried refers to the "record" button object, and the page is obtained through "w = document.getElementById("show").innerHTML" The weight in the label, then capture the element of the weighing mass column of this row through the button object, use the "text(w)" method to set the text content of the element to w, and record the current time in the weighing time column.
