It can effectively reduce the impact of environmental factors on the maintenance construction effect and improve the accuracy and objectivity of the hydraulic size control results.
[0022] According to one embodiment of the present invention, in step S101, historical construction data of multiple historical time periods are acquired, wherein the historical construction data includes: historical hydraulic magnitude, historical beam lifting height, historical beam weight and historical hydraulic pump parameters.
[0023] For example, historical construction data of multiple historical time periods are obtained, wherein the historical hydraulic size indicates the size of the hydraulic pressure required to be provided by the hydraulic system to complete the support maintenance construction task during the historical construction, the historical beam lifting height indicates the height to which the beam needs to be lifted to complete the support maintenance construction task, the historical beam weight indicates the weight of the beam, and the historical hydraulic pump parameters indicate the parameters of the hydraulic pump used in the historical time period, such as the friction of the hydraulic pump pipeline, the length of the hydraulic pump pipeline, the diameter of the hydraulic pump pipeline, the thickness of the hydraulic pump pipeline, and the material strength of the hydraulic pump pipeline.
[0024] According to an embodiment of the present invention, in step S102, historical environmental data of multiple historical time periods are acquired, wherein the historical environmental data includes: historical environmental temperature and historical environmental humidity.
[0025] For example, obtain the historical ambient temperature and historical ambient humidity of the construction environment for multiple historical time periods.
[0026] According to an embodiment of the present invention, in step S103, a hydraulic magnitude relationship function is determined based on the historical environmental data, the historical hydraulic magnitude, the historical beam body lifting height, the historical beam body weight and the historical hydraulic pump parameters.
[0027] According to one embodiment of the present invention, step S103 includes: Determining a historical pipeline friction resistance coefficient, a historical pipeline length, a historical pipeline diameter, a historical pipeline material strength, and a historical pipeline thickness based on the historical hydraulic pump parameters; Determining a historical transmission performance coefficient based on the historical pipeline friction resistance coefficient, the historical pipeline length, the historical pipeline diameter, the historical pipeline material strength, and the historical pipeline thickness; A hydraulic pressure magnitude relationship function is determined based on the historical environmental data, the historical transmission performance coefficient, the historical hydraulic pressure magnitude, the historical beam lifting height and the historical beam weight.
[0028] For example, determine the historical pipeline friction resistance coefficient, historical pipeline length, historical pipeline diameter, historical pipeline material strength and historical pipeline thickness of the hydraulic pump used in the historical time period; evaluate the transmission performance of the hydraulic pump pipeline of the hydraulic pump used in the historical time period based on the historical pipeline friction resistance coefficient, historical pipeline length, historical pipeline diameter, historical pipeline material strength and historical pipeline thickness, and determine the historical transmission performance coefficient; temperature, humidity, pipeline transmission performance, beam weight and historical beam lifting height all affect the hydraulic size to a certain extent. For example, the greater the beam weight, the greater the required hydraulic size, and the higher the beam lifting height, the greater the required hydraulic size. Based on the correlation of the above data, the hydraulic size relationship function between the historical environmental data, the historical transmission performance coefficient, the historical beam lifting height and the historical beam weight and the historical hydraulic size can be determined.
[0029] According to one embodiment of the present invention, the historical transmission performance coefficient is determined according to the historical pipeline friction resistance coefficient, the historical pipeline length, the historical pipeline diameter, the historical pipeline material strength and the historical pipeline thickness, including: determining the historical transmission performance coefficient of the hydraulic pump pipeline used in the kth historical time period according to formula (1): , (1) in, is the historical pipe material strength of the hydraulic pump pipe used in the kth historical time period, is the historical pipe diameter of the hydraulic pump pipe used in the kth historical time period, is the historical pipeline friction resistance coefficient of the hydraulic pump pipeline used in the kth historical time period, is the historical pipeline length of the hydraulic pump pipeline used in the kth historical time period, is the historical pipe thickness of the hydraulic pump pipe used in the kth historical time period, and h is the historical time period.
[0030] According to one embodiment of the present invention, It means that the smaller the friction coefficient of the historical pipeline is, the smaller the resistance encountered by the liquid during flow is, the higher the effective flow capacity of the hydraulic pump pipeline is, and the higher the transmission performance of the hydraulic pump pipeline is. is the historical pipeline material strength of the hydraulic pump pipeline used in the kth historical time period. The higher the pipeline material strength, the less likely the pipeline is to be deformed by external forces, the smaller the resistance of the fluid flowing in the pipeline, and the higher the transmission performance of the hydraulic pump pipeline. Indicates the material condition of the hydraulic pump pipeline. The larger the ratio, the better the material condition of the hydraulic pump pipeline and the higher the transmission performance of the hydraulic pump pipeline. represents the pipe radius of the hydraulic pump pipe used in the kth historical time period, represents the cross-sectional area of the hydraulic pump pipeline used in the kth historical time period, It is the ratio of the cross-sectional area of the hydraulic pump pipeline used in the kth historical time period to the historical pipeline length of the hydraulic pump pipeline used in the kth historical time period. The larger the ratio is, the stronger the flow capacity of the hydraulic pump pipeline used in the kth historical time period is, and the higher the transmission performance of the hydraulic pump pipeline is. It is the ratio of the historical pipeline diameter to the historical pipeline thickness of the hydraulic pump used in the kth historical time period. The smaller the ratio is, the thicker the pipeline of the hydraulic pump used in the kth historical time period is, which means the pipeline has a greater pressure bearing capacity, the more stable the fluid flow is, and the higher the transmission performance is. It indicates the effective flow capacity of the pipeline. The larger the ratio is, the stronger the effective flow capacity of the hydraulic pump pipeline is and the higher the transmission performance of the hydraulic pump pipeline is.
[0031] In this way, the historical transmission performance coefficient can be determined based on the historical pipeline friction resistance coefficient, historical pipeline length, historical pipeline diameter, historical pipeline material strength and historical pipeline thickness. During the calculation process, the effective flow capacity of the hydraulic pump pipeline can be evaluated based on the pipeline diameter, pipeline thickness and pipeline length. The material condition of the hydraulic pump pipeline can be evaluated based on the pipeline material strength and pipeline friction coefficient. Furthermore, the transmission performance of the hydraulic pump pipeline can be evaluated based on the effective flow capacity and material condition of the hydraulic pump pipeline, which improves the accuracy and comprehensiveness of the historical transmission performance coefficient and provides a data basis for subsequent calculations.
[0032] According to one embodiment of the present invention, determining a hydraulic pressure magnitude relationship function according to the historical environmental data, the historical transmission performance coefficient, the historical hydraulic pressure magnitude, the historical beam body lifting height and the historical beam body weight includes: Determine the standard operating temperature and standard operating humidity of the hydraulic pump; Determining a standard working environment vector according to the standard working temperature and the standard working humidity; Determining a historical environment vector according to the historical environment temperature and the historical environment humidity; A hydraulic magnitude relationship function is determined according to the standard working environment vector, the historical environment vector, the historical transmission performance coefficient, the historical hydraulic magnitude, the historical beam lifting height and the historical beam weight.
[0033] For example, obtain the temperature and humidity that can support the normal work and operation of the hydraulic pump, that is, the standard working temperature and standard working humidity; combine the standard working temperature and standard working humidity into a standard working environment vector; combine the historical ambient temperature and historical ambient humidity in a historical time period into a historical environment vector; determine the hydraulic size relationship function between the standard working environment vector, the historical environment vector, the historical transmission performance coefficient, the historical beam lifting height and the historical beam weight and the historical hydraulic size.
[0034] According to one embodiment of the present invention, the hydraulic pressure magnitude relationship function is determined according to the standard working environment vector, the historical environment vector, the historical transmission performance coefficient, the historical hydraulic pressure magnitude, the historical beam body lifting height and the historical beam body weight, including: obtaining a first undetermined coefficient equation of the hydraulic pressure magnitude relationship function according to formula (2), (2) in, is the historical hydraulic pressure of the hydraulic pump used in the kth historical time period at the i-th moment in the historical time period, is the historical beam elevation height in the kth historical time period, is the historical beam weight of the kth historical time period, is the historical transmission performance coefficient of the hydraulic pump pipeline used in the kth historical time period, is the historical ambient temperature at the i-th moment of the k-th historical time period, is the historical ambient humidity at the i-th moment of the k-th historical time period, The historical environment vector at the i-th moment of the k-th historical time period, for The transposed vector of is the standard operating temperature, is the standard working humidity, is the standard working environment vector, h is the historical time period, , , , , , , , , and is the first undetermined coefficient of the first undetermined coefficient equation; Solving the first undetermined coefficient according to the standard working environment vector, the historical environment vector, the historical transmission performance coefficient, the historical hydraulic pressure size, the historical beam lifting height and the historical beam weight to obtain a solution value of the first undetermined coefficient; The hydraulic magnitude relationship function is obtained according to the solved value of the first undetermined coefficient and the first undetermined coefficient equation.
[0035] According to one embodiment of the present invention, It means that the height of beam lifting is positively correlated with the hydraulic pressure. When the height of beam lifting is higher, the force required by the hydraulic system to lift the beam is greater, and the hydraulic pressure required by the hydraulic system is greater. It means that the weight of the beam is positively correlated with the hydraulic pressure. The heavier the beam is, the greater the hydraulic pressure the hydraulic system needs to provide. It means that the transmission performance coefficient is negatively correlated with the hydraulic pressure. When the transmission performance coefficient is larger, the transmission performance of the hydraulic pump is better, which will reduce the pressure loss of the liquid during the transmission process, and the hydraulic pressure required by the hydraulic system is smaller. It represents the benchmark hydraulic pressure size of the kth historical time period determined by fitting the historical beam lifting height, historical beam weight and historical transmission performance coefficient of the kth historical time period.
[0036] According to one embodiment of the present invention, is the cosine similarity between the historical environment vector at the i-th moment of the k-th historical time period and the standard working environment vector. The larger the cosine similarity, the closer the historical environment temperature and humidity at the i-th moment of the k-th historical time period are to the standard working temperature and humidity, and the smaller the impact of temperature and humidity factors on hydraulic pressure. is a function to be fitted in the form of a sine function, representing a fitting term with a certain periodicity. For example, the current temperature is 20 degrees, and half an hour later, the temperature changes to 25 degrees. In a change cycle, the temperature data and humidity data have a temporary impact on the hydraulic pressure. In the figure, the cosine similarity between the historical environment vector at the ith moment of the kth historical time period and the standard working environment vector has a negative correlation with the historical hydraulic pressure, that is, the difference between the historical ambient temperature and the historical ambient humidity and the standard working temperature and the standard working humidity has a positive correlation with the historical hydraulic pressure. For example, when the ambient temperature is too low, the viscosity of the hydraulic oil is too high, which will increase the system resistance and the oil flow, making the hydraulic system run slower and even causing difficulty in starting the hydraulic pump. The actual hydraulic pressure is reduced and it is necessary to increase the pressure provided by the hydraulic pump, that is, the historical hydraulic pressure becomes larger. When the ambient temperature is too high, the viscosity of the hydraulic oil is too low, which is easy to cause leakage and internal pressure relief, thereby affecting the normal output pressure of the hydraulic pump and causing the actual hydraulic pressure to drop. When the actual hydraulic pressure decreases, it is necessary to increase the pressure provided by the hydraulic pump, that is, the size of the historical hydraulic pressure becomes larger. When the ambient humidity is too high, moisture can easily penetrate into the interior of the hydraulic pump and mix with the hydraulic oil, changing the properties of the hydraulic oil, resulting in a decrease in its lubrication and sealing performance. The actual hydraulic pressure decreases, and it is necessary to increase the pressure provided by the hydraulic pump, that is, the size of the historical hydraulic pressure becomes larger. When the ambient humidity is too low, the interior of the hydraulic pump may lack sufficient moisture, causing some parts (such as metal parts) to be more easily worn due to dryness, resulting in a decrease in the actual hydraulic pressure. It is necessary to increase the pressure provided by the hydraulic pump, that is, the size of the historical hydraulic pressure becomes larger. Therefore, the cosine similarity between the historical environment vector at the i-th moment of the k-th historical time period and the standard working environment vector is used as the denominator.
[0037] According to one embodiment of the present invention, fitting can be performed based on multiple parameters involved in the above first undetermined coefficient equation, based on the standard working environment vector, historical environment vector, historical transmission performance coefficient, historical hydraulic size, historical beam lifting height and historical beam weight, to solve the above multiple first undetermined coefficients. There are 10 first undetermined coefficients, namely, , , , , , , , , and , according to the standard working environment vector, historical environment vector, historical transmission performance coefficient, historical hydraulic size, historical beam lifting height and historical beam weight at at least 10 moments in the historical time period, the above 10 first undetermined coefficients are solved to obtain the solution values of the above 10 first undetermined coefficients, and the solution values of the above 10 first undetermined coefficients are substituted into the first undetermined coefficient equation to determine the hydraulic size relationship function.
[0038] In this way, the hydraulic size relationship function can be determined based on the standard working environment vector, historical environment vector, historical transmission performance coefficient, historical hydraulic size, historical beam lifting height and historical beam weight, accurately describing the relationship between beam lifting height, beam weight, transmission performance coefficient and hydraulic size, as well as the transient effects of temperature and humidity changes on hydraulic size, thereby improving the accuracy and objectivity of the hydraulic size relationship function.
[0039] According to one embodiment of the present invention, in step S104, weather forecast information, beam data and hydraulic pump parameters of the current time period are obtained, wherein the weather forecast information includes: ambient temperature and ambient humidity, and the beam data includes: beam lifting height and beam weight.
[0040] For example, the expected completion time of the work is set as the current time period (for example, if the maintenance work is expected to be completed in 4 hours, the current time period is 4 hours), and the ambient temperature and humidity from the current time to the end of the time period are obtained through the weather forecast website; the hydraulic pump pipeline friction resistance coefficient, pipeline length, pipeline diameter, pipeline material strength and pipeline thickness of the hydraulic pump used in the current construction and maintenance are obtained; the weight and lifting height of the beam required to be lifted for the current construction and maintenance are obtained.
[0041] According to an embodiment of the present invention, in step S105, the hydraulic pressure level in the current time period is determined based on the hydraulic pressure level relationship function, the weather forecast information, the beam body data and the hydraulic pump parameters.
[0042] According to one embodiment of the present invention, step S105 includes: Determine, based on the hydraulic pump parameters, a hydraulic pump pipeline friction resistance coefficient, a pipeline length, a pipeline diameter, a pipeline material strength, and a pipeline thickness of the hydraulic pump used in the current time period; Determine the transmission performance coefficient of the hydraulic pump pipeline used in the current time period according to the pipeline friction resistance coefficient, the pipeline length, the pipeline diameter, the pipeline material strength and the pipeline thickness; Determining a real-time environmental vector according to the environmental temperature and the environmental humidity; The hydraulic pressure size of the current time period is determined according to the hydraulic pressure size relationship function, the real-time environment vector, the beam lifting height, the beam weight and the transmission performance coefficient.
[0043] For example, the transmission performance coefficient of the hydraulic pump used in the current time period is determined according to the pipeline friction resistance coefficient, pipeline length, pipeline diameter, pipeline material strength and pipeline thickness. The calculation method of the transmission performance coefficient of the hydraulic pump used in the current time period is similar to formula (1) and is not repeated here. The real-time environmental vector is determined according to the ambient temperature and ambient humidity of the current time period. The real-time environmental vector, the beam lifting height, the beam weight and the transmission performance coefficient are substituted into the hydraulic size relationship function to determine the hydraulic size at multiple moments in the current time period.
[0044] According to one embodiment of the present invention, the hydraulic pressure in the current time period is determined according to the hydraulic pressure relationship function, the real-time environment vector, the beam lifting height, the beam weight and the transmission performance coefficient, including: determining the hydraulic pressure at the i-th moment in the current time period according to formula (3): , (3) in, is the height of the beam during the current time period, is the weight of the beam in the current time period, The transmission performance coefficient of the hydraulic pump used in the current time period, is the ambient temperature at the i-th moment of the current time period, is the ambient humidity at the i-th moment of the current time period, is the real-time environment vector at the i-th moment of the current time period, for The transposed vector of is the standard operating temperature, is the standard working humidity, is the standard working environment vector, for The solution value of for The solution value of for The solution value of for The solution value of for The solution value of for The solution value of for The solution value of for The solution value of for The solution value of for The solution value of .
[0045] According to one embodiment of the present invention, the real-time environment vector, beam lifting height, beam weight and transmission performance coefficient can be substituted into the hydraulic magnitude relationship function to obtain formula (3), thereby obtaining the hydraulic magnitudes at multiple moments in the current time period.
[0046] In this way, the hydraulic magnitude at multiple moments in the current time period can be determined based on the hydraulic magnitude relationship function, the real-time environmental vector, the beam lifting height, the beam weight and the transmission performance coefficient, thereby improving the accuracy and scientificity of the hydraulic magnitude.
