Description

Technical Field

[0001] The present invention relates to the technical field of hose matching detection, and particularly to a hose matching detection method and system. Background Art

[0002] As a key component in hydraulic systems and other fluid transmission systems, hoses play a crucial role in industrial, agricultural, and household applications; they are typically used to connect various hydraulic components in a hydraulic system to ensure the effective and safe transmission of fluids within the system; the performance and quality of hoses are directly related to the operating efficiency and safety of the entire system, so it is particularly important to conduct strict matching detection on them;

[0003] Existing hose matching detection methods may not fully consider the importance of hoses in the system and only perform matching based on the physical properties of hoses (such as length, diameter, pressure resistance, etc.), which may lead to insufficient attention being paid to hoses on critical paths, thus affecting the performance and reliability of the entire system; secondly, existing hose matching methods often perform matching detection by separately matching all hoses to be matched with all placement positions without screening, which results in low efficiency of matching detection; in addition, existing hose matching methods often do not use optimization algorithms to find the optimal matching scheme but rely on experience or simple rules for matching, which may lead to a decrease in the accuracy of hose matching detection.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] Refer to Figure 1 , the present invention provides a hose matching detection method, including:

[0049] Step 1: Establish a hose connection model, calculate the number of adjacent hoses for each hose and the shortest path length from the input and output devices, and calculate the comprehensive path length of each hose in combination with the usage frequency of the input and output devices; calculate the importance index of each hose based on the number of adjacent hoses and the comprehensive path length, and assign the importance index to the corresponding placement position of each hose;

[0050] The first step includes the following steps:

[0051] Step 101: Obtain the connection schematic diagram of the hoses, and number each placement position of the hoses in the connection schematic diagram. Among them, the hoses are connected to each other, the hoses are connected to the input devices, and the hoses are connected to the output devices through hose connectors; each input device and each output device are also numbered;

[0056] Step 104: Combine the shortest path lengths from each rubber hose to each input device and each output device and respectively with the usage frequencies of each input device and each output device and to obtain the comprehensive path length of each rubber hose , and the expression is: , where represents the total number of associated input devices of each rubber hose, represents the total number of associated output devices of each rubber hose;

[0057] When a certain input device or a certain output device starts to transmit the material flow, not all rubber hoses are used for transmission. Each input device and output device is recorded as the associated input device and associated output device of the rubber hoses it uses, and each rubber hose has several associated input devices and associated output devices;

[0058] Step 105: Combine the number of adjacent rubber hoses of each rubber hose and the comprehensive path length of each rubber hose , and calculate the importance index of each rubber hose , and the expression is: ;

[0059] Among them, , respectively represent the number of adjacent rubber hoses and the comprehensive path length The preset weight coefficient, the specific value of which is set by the hose matching management personnel themselves, and ;

[0060] In the hose connection model, the number of each hose is the same as the number of the corresponding position to be placed, so the importance index of each position to be placed is the same as the importance index of the corresponding hose equal, and the same is used to represent the importance index of each position to be placed.

[0061] When in use, combine the content in steps 101 to 105:

[0063] Step Two: Based on the relevant data of each hose to be matched, conduct three screenings on the hoses to be matched at each position to be placed, and obtain the third candidate hose set at each position to be placed;

[0064] The said step two includes the following steps:

[0065] Step 201: Obtain all hoses to be matched, and obtain the relevant data of each hose to be matched, including hose length, hose diameter, maximum fluid pressure and fluid temperature that can be withstood, and corrosion resistance data;

[0066] Obtain the historical transportation record data of each hose, that is, the monitoring data of the material flow transmitted by each hose in history, including the transmission flow data in each hose, and the real-time fluid pressure data and real-time fluid temperature data borne at key positions; the said key positions are the two ends of the hose and the midpoint position of the hose cross-section, and the transmission flow data is fixed;

[0069] Step 203: Sequentially obtain the historical transportation record data of the hoses associated with each material flow, and from it, obtain the real-time fluid pressure data and real-time fluid temperature data borne at key positions, and obtain the maximum fluid pressure and maximum fluid temperature data from all the historical transportation record data of this associated hose;

[0070] Combining the historical transportation record data of all material flows, obtain and record the maximum fluid pressure and maximum fluid temperature data of the hoses at each position to be placed; for example, if a hose at a position to be placed is simultaneously an associated hose of two material flows, then combine the real-time fluid pressure and real-time fluid temperature data in the historical transportation record data of these two material flows; obtain the actual maximum fluid pressure and actual maximum fluid temperature data of the hoses at all positions to be placed after combination;

[0071] Sequentially obtain the maximum fluid pressure and fluid temperature data that each hose to be matched in the second set of candidate hoses at each position to be placed can bear, and perform a third screening in combination with the actual maximum fluid pressure and actual maximum fluid temperature data of the hoses at the corresponding positions to be placed, and retain the hoses to be matched whose maximum fluid pressure and fluid temperature that can be borne are respectively greater than the actual maximum fluid pressure and actual maximum fluid temperature, to obtain the third set of candidate hoses at each position to be placed.

[0072] During use, combine the content in Steps 201 to 203:

[0074] Step Three: Simulate the material flow transportation process of each hose in the third set of candidate hoses, measure the average outer diameter change rate of the hose surface, and obtain the matching index of each hose to be matched with the current position to be placed after standardization;

[0075] The steps in Step Three include the following steps:

[0077] Sequentially obtain the historical transportation record data of the hoses historically placed at each position to be placed, and summarize the historical transportation record data of all hoses to obtain several groups of historical transportation record data; classify these historical transportation record data according to the types of material flows transmitted;

[0078] It should be noted that each rubber hose historically placed at each position to be placed refers to all the rubber hoses during the actual material flow transportation at this position;

[0079] Step 302: Select a set of historical transportation record data from several groups of classified historical transportation record data in sequence, and obtain the real-time fluid pressure data and real-time fluid temperature data at each key position during the material flow transportation from the historical transportation record data;

[0081] Perform a mean operation on the average fluid pressure data and average fluid temperature data of all historical transportation record data of the same type of material flow to obtain the comprehensive fluid pressure data and comprehensive fluid temperature data of each type of material flow, which are used for the transportation simulation of the rubber hoses to be matched later;

[0082] Step 303: Select a pressure pump, a flow meter, and a temperature sensor to construct a transportation simulation device, select the type of material flow to be simulated, select the rubber hose to be matched from the third set of candidate rubber hoses at the current position to be placed in sequence, and install it on the transportation simulation device;

[0083] Perform a material flow transmission simulation on the corresponding material flow according to the fixed transmission flow rate data, the corresponding comprehensive fluid pressure data, and the comprehensive fluid temperature data; After the transmission simulation is completed, use a caliper to measure the outer diameter changes at each part of the rubber hose surface, and calculate the average outer diameter change rate of the rubber hose surface to be matched based on definite integrals , the expression is: , where represents the length of the rubber hose, 、 respectively represent the outer diameter changes at each part of the rubber hose surface before and after the transportation simulation;

[0084] Step 304: After calculating the average outer diameter change rates of all the rubber hoses to be matched in the third set of candidate rubber hoses, perform a normalization process on the average outer diameter change rates of the surfaces of these rubber hoses to be matched to obtain the matching index of these rubber hoses to the current position to be placed , the expression is: , where represents the A hose to be matched Indicates the average outer diameter change rate of the surface of the hoses to be matched 、 respectively represent the maximum and minimum values of the average outer diameter change rate of the surface of the hoses to be matched

[0085] Based on the third candidate hose set at each position to be placed calculated in Step 3, calculate the matching index between each hose to be matched in the set and the current position to be placed

[0086] During use, combine the content in Steps 301 to 304

[0087] By simulating the material flow transportation process, measure and calculate the average outer diameter change rate of the hose surface, and then standardize to obtain the matching index between the hose and the position to be placed. This comprehensively considers the performance of the hose under actual working conditions, provides a more accurate and reliable basis for the matching selection of the hose, and helps to improve the efficiency of hose use

[0088] Step 4: Construct an initial population; calculate the fitness of each individual in the initial population based on the importance index of the position to be placed and the matching index of the selected hose; generate new individuals through crossover and mutation operations, and perform iterative optimization until the termination condition is met, and output the individual with the highest fitness as the optimal hose matching method

[0089] The said Step 4 includes the following steps

[0090] Step 401: Select the type of material flow, obtain the transmission line of the material flow, start from the associated input device of the material flow, number each position to be placed on the transmission line with a first type of number, and number each hose to be matched in the third candidate hose set at each position to be placed with a second type of number

[0091] Randomly select a hose to be matched from the third candidate hose set at each position to be placed, and record it as an initial individual in the form of [first type of number - second type of number, first type of number - second type of number,...]; repeat the above operation several times to obtain multiple initial individuals, and these initial individuals form an initial population

[0092] Step 402: Calculate the fitness of each initial individual in the initial population based on the importance index of each position to be placed on the transmission line and the matching index of the selected hose to be matched The expression is where Indicates the importance index of the Indicates the matching index of the hose to be matched selected at the Indicates the total number of positions to be placed on the current transmission line;

[0093] Step 403: Select the two initial individuals with the highest fitness as parents, perform crossover operations on the parents, and perform mutation operations on the generated offspring individuals. Among them, the crossover operation means randomly selecting a crossover point in the individuals of the two parents and exchanging the parts after the crossover point in the two parent individuals to generate two new offspring individuals. The mutation operation means randomly changing the selected hose to be matched at a certain position to be placed of the offspring individual into another hose to be matched, and the other hose to be matched also comes from the third set of candidate hoses at the corresponding position to be placed;

[0094] Calculate the fitness of the individuals generated after the crossover operation and the mutation operation, and put these individuals into the initial individuals;

[0095] Step 404: Repeat Step 403 to perform iterative optimization of hose matching selection, and set termination conditions to determine when to stop the iterative optimization process;

[0096] (1) Set a maximum number of iterations. When the number of iterations reaches this value, stop the optimization process regardless of whether the fitness value converges;

[0097] (2) If within a preset number of multiple iterations, the improvement amplitude of the optimal fitness value is less than a preset threshold, it is considered that the algorithm has converged and stop the optimization process;

[0098] The above-mentioned maximum number of iterations, preset number of multiple iterations, and preset threshold are all set by the hose matching management personnel themselves, and the optimization iteration process stops when any of the above conditions is met;

[0099] Output the individual with the highest fitness in the current initial individuals, and use it as the hose matching method for the corresponding material flow transmission. Select the hose matching method for all material flows according to Steps 401 - 404.

[0100] When in use, combine the content in Steps 401 to 404:

[0101] By constructing an initial population, calculating the individual fitness by combining the importance index of the position to be placed and the matching index of the hose, and using the crossover and mutation operations in the genetic algorithm for iterative optimization, finally output the individual with the highest fitness as the optimal hose matching method. It not only considers the matching of the hose and the position to be placed, but also incorporates the importance of the position, and realizes the optimal selection of hose matching through an intelligent algorithm, improving the rationality of hose use and the system transmission efficiency.
