Technical Field

[0001] The present invention relates to the technical field of concrete maturity, and in particular to a concrete maturity prediction system, method, electronic equipment and storage medium. Background Art

[0002] Concrete maturity is an important indicator for evaluating concrete performance and strength development. Currently, the maturity of concrete is usually judged by making the concrete into cubic or cylindrical specimens, curing according to design requirements, and then sampling within climatic conditions and the required time limit. The maturity of the concrete can be preliminarily judged by observing the color and spot distribution on the surface. Alternatively, cubic or cylindrical specimens are made according to design requirements, sampling is carried out within climatic conditions and the required time limit, and the specimens are crushed in the laboratory. The maturity of the concrete is estimated based on the test results.

[0003] The above method is highly dependent on the test personnel, which not only increases the complexity of the operation, but also the test results are greatly affected by human factors, and the stability of the test results is poor. At the same time, the test piece needs to be made first during the test, which takes a long time, and it is not a real-time test. The judgment has a lag, which will cause certain errors in the evaluation of concrete performance and strength development. Therefore, in order to solve the above problems, a concrete maturity prediction system, method, electronic device and storage medium are needed. Summary of the invention

[0004] The main purpose of the present invention is to provide a concrete maturity prediction system, method, electronic device and storage medium that reduce the influence of human detection factors, facilitate detection, detect in a timely manner and have high accuracy and stability.

[0006] Preferably, the current acquisition module in the data acquisition module includes: A current signal input module, used for receiving an external current signal; A current transformer module, used to detect current signals and convert them into measurable electrical signals; The current circuit resistance module is composed of resistors to form a voltage divider circuit; A capacitor module, connected in parallel with the resistor in the resistor module, for filtering and stabilizing voltage; Output terminal module, used for outputting current signal.

[0007] Preferably, the voltage acquisition module in the data acquisition module includes: A voltage signal input module, used for receiving an external voltage signal; An operational amplifier module, used to amplify the received voltage signal; Capacitor and rectifier diode bridge modules for filtering and converting the output voltage to DC voltage; The voltage circuit resistance module is composed of resistors, which together form a voltage divider circuit to adjust the input voltage.

[0008] In a second aspect, the present invention further provides a concrete maturity prediction method, using any of the above concrete maturity prediction systems, The prediction method includes the following steps: S1. First, the voltage and current data of the mixing device are collected in real time to calculate the real-time power of the mixing device; at the same time, the real-time power of the mixing device is derived at least once to obtain the power fluctuation rate of the mixing device, and the parameters corresponding to the maturity of the concrete are manually detected. Through data analysis, the abnormal fluctuations of parameters such as material sticking, voltage instability, and mixing time under different mix ratios are filtered out, and a data model of the power fluctuation rate of the mixing device and the maturity of the concrete is established; S2. The established data model is implanted into the control module. During the concrete mixing process, the data acquisition module collects the voltage and current data of the mixing device in real time, and obtains the real-time power of the mixing device through the calculation module. The real-time power is derivatized at least once through the calculation module to obtain the power fluctuation rate of the mixing device, and then the power fluctuation rate is brought into the data model to predict the maturity of the concrete.

[0009] Preferably, the number of times the real-time power is derived is three times.

[0010] In a third aspect, the present invention further provides an electronic device, including a processor and a memory; The processor is connected to the memory; The memory is used to store executable program code; The processor runs a program corresponding to the executable program code by reading the executable program code stored in the memory, so as to execute any of the above-mentioned methods.

[0011] In a fourth aspect, the present invention further provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program implements any of the above-described methods when executed by a processor.

[0012] The beneficial effects of the present invention are: The present invention obtains the voltage and current data of the mixing device in advance to calculate the power; then the power is derived to obtain the power fluctuation rate, and the corresponding concrete maturity parameter manually detected at this time is obtained, and a prediction data model of the power fluctuation rate of the mixing device and the concrete maturity is established through data analysis; Then, the data model is implanted into the control module to obtain the real-time voltage and current data during the mixing process, calculate the real-time power of the mixing device, and obtain the power fluctuation rate of the mixing device by taking the derivative of the real-time power. Then, the power fluctuation rate is brought into the data model to predict the maturity of the concrete. On the one hand, the present invention collects real-time current and voltage data, and the corresponding parameters of the obtained maturity are also real-time, the prediction is timely, there is no lag, and the accuracy is higher; on the other hand, the prediction results can be intuitively seen from the display module, and there is no need to conduct detection tests, which reduces the complexity of operation, makes detection more convenient, and has higher detection efficiency. At the same time, the influence of human detection factors is reduced, and the detection stability is improved; Different from using only a single parameter such as current or voltage to predict maturity, in the present invention, power is the work done by the mixing motor per unit time, which can comprehensively consider multiple factors in the mixing process, such as the viscosity of concrete, mixing speed and time, etc.; the derivation of power can not only reflect the load condition of the mixing motor, but also provide detailed information on energy transfer and consumption during the mixing process, and can monitor the energy changes in the mixing process in real time, which is helpful for a more comprehensive understanding of the energy dynamics of the mixing process, and can also infer the mixing state and mixing effect of the concrete, so as to more accurately predict and evaluate the mixing efficiency and mixing quality of the concrete; In large-scale mixing plants or some complex mixing scenarios where precise control of mixing quality is required, the judgment relying solely on a single parameter such as current or voltage can no longer meet the accuracy requirements of concrete maturity judgment. In the present invention, power is used for derivation to predict concrete maturity. It uses instantaneous energy to represent the effect of mixing equipment on materials, which is not easily affected by other factors, can better characterize the effect of mixing on materials, and has better stability. The derivation is achieved by finding the tangent of the power curve and the rate of change, which can well shield the influence of special factors such as material jamming, automatically filter out the influence of related abnormalities or external factors, and is more conducive to ensuring the accuracy of concrete maturity judgment.

[0018] Example 1

[0019] like Figure 1 As shown, the first aspect of the present invention provides a concrete maturity prediction system, comprising: A data acquisition module is used to collect current and voltage data of the stirring device within a preset time; the current and voltage data of the stirring device here are the current and voltage data of the stirring motor of the stirring device; A calculation module, used for calculating the power of the stirring device according to the current and voltage data of the stirring device; According to the power, the time is differentiated at least once to obtain the power fluctuation rate; by taking multiple derivatives, without using other methods, the change of the derivative itself can be used to automatically shield the influence of abnormal factors better, so that the obtained fluctuation rate is more in line with the theoretical law, making the prediction more accurate.

[0020] And, convert the power fluctuation rate and fluctuation range into percentage to obtain maturity; in, The power calculation formula is: P=UI (P is power, U is voltage, I is current), The formula for the derivation of electric power with respect to time is: dP / dt==U*dI / dt+I*dU / dt; Display module: used to display data such as voltage, current, power, power fluctuation rate, maturity, etc.; and, Control module: used to control the data acquisition module, calculation module and display module; Communication module: used for communication between data acquisition module, calculation module, display module and control module.

[0021] The prediction system of the present invention can collect current and voltage data in real time, obtain real-time maturity corresponding parameters, and make the prediction more accurate; on the other hand, the prediction result can be intuitively seen from the display module, and there is no need to conduct detection tests, which reduces the complexity of operation, makes detection more convenient, and has higher detection efficiency. At the same time, the influence of human detection factors is reduced, and the detection stability is improved; the concrete maturity is predicted by taking derivative of power, and the power is equivalent to instantaneous energy at this time. It uses instantaneous energy to represent the effect of the mixing equipment on the material, is not easily affected by other factors, can better characterize the effect of mixing on the material, and has better stability; the power is derived by finding the tangent of the power curve and the rate of change, which can shield the influence of special factors such as stuck materials, reduce the influence of adverse factors, and is more conducive to ensuring the accuracy of the judgment of the concrete maturity.

[0022] At the same time, the value derived from the power curve indicates the maturity of the concrete. After multiple derivations, the closer the maturity value is to 0 or the set standard value, the more mature the concrete mixing is. The higher the concrete mixing maturity, that is, the closer the value is to 0, the closer the maturity of the concrete is to the design value. For example, if the design slump of concrete is 180±20mm and the spread is 480±20mm, if the concrete maturity value is closer to 0, then the slump of the concrete is closer to 180mm, the spread is closer to 480mm, the closer the maturity of the concrete is to the design value, and the more accurate the prediction is; while for immature concrete, the maturity value will not approach 0.

[0023] In some embodiments of the present invention, the display module and the control module of the present invention may be industrial computers with display screens.

[0024] In some embodiments of the present invention, the current acquisition module in the data acquisition module of the present invention includes: A current signal input module, used for receiving an external current signal; A current transformer module, used to detect current signals and convert them into measurable electrical signals; The current circuit resistance module is composed of resistors to form a voltage divider circuit; A capacitor module, connected in parallel with the resistor in the resistor module, is used for filtering and stabilizing the voltage; Output terminal module, used for outputting current signal.

[0025] like Figure 3 As shown, it is a current acquisition circuit diagram when the voltage acquisition module is specifically implemented. The circuit includes a current transformer, two capacitors C2 and C3, and three resistors R1, R3 and R5. The secondary side of the current transformer is connected to an external current signal source through resistor R1 and is also connected to one end of capacitor C2; the other end of capacitor C3 is connected to an external current signal source through resistor R3; the other end of capacitor C2 is connected to an external current signal source through resistor R5.

[0026] When the current transformer inputs current, the voltage signal it generates passes through resistor R1 and enters the two ends of capacitor C2. At this time, capacitor C2 filters the voltage signal, thereby reducing the fluctuation of the current signal. Then, the other end of capacitor C2 is connected to the external current signal source through resistor R3 to further reduce the fluctuation of the current signal. Finally, the other end of capacitor C3 is connected to the external current signal source through resistor R5, and the current signal is filtered again to ensure the stability and accuracy of the current signal.

[0027] Through the circuit design, the present invention can suppress the fluctuation of the current signal to a certain extent and improve the stability of the current transformer. In addition, the circuit structure is simple, easy to implement, and has low cost and high practical value.

[0028] In some embodiments of the present invention, the voltage acquisition module in the data acquisition module of the present invention includes: A voltage signal input module, used for receiving an external voltage signal; An operational amplifier module, used to amplify the received voltage signal; Capacitor and rectifier diode bridge modules for filtering and converting the output voltage to DC voltage; The voltage circuit resistance module is composed of resistors, which together form a voltage divider circuit to adjust the input voltage.

[0029] like Figure 4 As shown, it is a voltage acquisition circuit diagram when the voltage acquisition module is specifically implemented. It includes: an operational amplifier U1; A capacitor C1 and a resistor R6; A rectifier diode bridge stack (TV1); A current type voltage transformer (ZMPT107-1) and two resistors R2 and R4; A grounding screw PE1; Among them, pin 1 of U1 is connected to AVDD, pin 2 is connected to AGND, pin 3 is connected to one end of C1, and pin 5 is connected to pin 1 of P2; the other end of C1 is connected to one end of R6, and the other end of R6 is connected to AGND; the two ends of the primary winding of TV1 are respectively connected to pin 3 of U1 and the other end of C1, and the two ends of the secondary winding are respectively connected to one end of R2 and R4; the other end of R2 is connected to AGND, and the other end of R4 is connected to PE1; pin 1 of P2 is connected to AGND through PE1.

[0030] The input voltage is divided by resistors (R2, R4, R6) to obtain a suitable voltage value; the divided voltage enters the operational amplifier (U1) and is amplified by its internal gain amplifier; the amplified voltage is transmitted to the input end of the operational amplifier (U1) through the primary winding of the current-type voltage transformer (ZMPT107-1); the output end of the operational amplifier (U1) is connected to a capacitor (C1) and a rectifier diode bridge stack (TV1), the capacitor (C1) is used for filtering, and the rectifier diode bridge stack (TV1) converts the AC voltage into a DC voltage, and finally outputs a stable DC voltage.

[0031] like Figure 5 As shown in the figure, it is a power waveform captured on site. According to this analysis, a mixing cycle can be divided into a no-load stage, a material unloading mixing stage, a stable mixing stage, and then unloading and entering the next mixing cycle. Figure 6 shown.

[0032] 1. No-load power: The power change rate in the no-load stage is extremely small and the power derivative is close to 0.

[0033] 2.Power during feeding and stirring stage: The power in the feeding and mixing stage is the mixing power of the mixing device during the feeding process of concrete raw materials. The power fluctuates greatly in this process, the slump is not formed, the reference is poor, and the power derivative is large and messy.

[0034] 3. Power during stable stirring stage: The power in the stable mixing stage is the power after the concrete materials enter the mixing cylinder and are evenly mixed. The power changes steadily, the power derivative is small, the materials are complete, and the slump has been formed. This stage is used to predict the maturity of concrete.

[0035] like Figure 2 As shown, based on the above description, in some embodiments of the present invention, the method for predicting concrete maturity includes the following steps: S1. First, the voltage and current data of the mixing device are collected in real time to calculate the real-time power of the mixing device; at the same time, the real-time power of the mixing device is derived at least once to obtain the power fluctuation rate of the mixing device, and the parameters corresponding to the maturity of the concrete are manually detected. Through data analysis, abnormal fluctuations of parameters such as material sticking, voltage instability, and mixing time under different mix ratios (different mix ratios have different mixing times) are automatically filtered, and a data model of the power fluctuation rate of the mixing device and the maturity of the concrete is established; S2. The established data model is implanted into the control module. During the concrete mixing process, the data acquisition module collects the voltage and current data of the mixing device in real time, and obtains the real-time power of the mixing device through the calculation module. The real-time power is derivatized three times through the calculation module to obtain the power fluctuation rate of the mixing device, and then the power fluctuation rate is brought into the data model to predict the maturity of the concrete.

[0036] The present invention obtains the voltage and current data of the mixing device in advance to calculate the power; then the power is derived to obtain the power fluctuation rate, and the corresponding concrete maturity parameter manually detected at this time is obtained, and a prediction data model of the power fluctuation rate of the mixing device and the concrete maturity is established through data analysis; Then, the data model is implanted into the control module to obtain the real-time voltage and current data during the mixing process, calculate the real-time power of the mixing device, and obtain the power fluctuation rate of the mixing device by taking the derivative of the real-time power. Then, the power fluctuation rate is brought into the data model to predict the maturity of the concrete. On the one hand, the present invention collects real-time current and voltage data, and the obtained maturity corresponding parameters are also real-time, and the prediction accuracy is higher; on the other hand, the prediction results can be intuitively seen from the display module, and there is no need to conduct detection tests, which reduces the complexity of operation, makes detection more convenient, and has higher detection efficiency.

Optionally, the processor may be implemented in at least one hardware form of DSP, FPGA, and PLA. The processor may integrate one or a combination of CPU, GPU, modem, etc. The CPU mainly processes the operating system, user interface, and application program; the GPU is responsible for rendering and drawing the content to be displayed on the display screen; and the modem is used to process wireless communication.

[0038] It is understandable that the above-mentioned modem may not be integrated into the processor, but may be implemented by a separate chip.

[0041] In the absence of conflict, the technical features in this embodiment and implementation scheme can be combined arbitrarily.

Designers can "integrate" a digital system on a PLD by programming themselves, without having to ask chip manufacturers to design and make dedicated integrated circuit chips. Moreover, nowadays, instead of manually making integrated circuit chips, this programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when writing program development, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL), and there is not only one HDL, but many kinds.

[0045] 3. By predicting the maturity of concrete, the later quality and reliability of concrete can be evaluated.

[0046] 4. By real-time monitoring of the maturity of concrete, possible problems in construction can be discovered in time, so that corresponding measures can be taken to adjust and correct them to ensure construction quality.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
