Description

Technical Field

[0001] This invention relates to the field of cleaning machine cycle control technology, specifically a cleaning cycle control system based on a cleaning machine. Background Technology

[0002] Cleaning machines are used to flush and filter contaminants generated or introduced into hydraulic systems during manufacturing, assembly, use, and maintenance. They can also be used for the periodic maintenance and filtration of working fluids to improve cleanliness, avoid or reduce malfunctions caused by contamination, and thus ensure the high performance, high reliability, and long service life of hydraulic system equipment.

[0003] However, some existing cleaning machine control systems only allow operators to perform a fixed number of cleaning cycles on the internal objects based on the provided number of cleaning cycles. This results in a waste of resources if too many cleaning cycles are set, and an inefficient cleaning if too few cycles are set, thus preventing operators from freely selecting the number of cleaning cycles according to customer needs and actual conditions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cleaning cycle control system based on a cleaning machine, which solves the problem of not being able to freely select the number of cleaning cycles according to customer needs and actual conditions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cleaning cycle control system based on a cleaning machine, comprising:

[0006] The cleaning data acquisition module is used to acquire the parameters set by the cleaning machine, including the number of cleaning cycles initially set by the operator. These parameters are then transmitted to the residue content monitoring module.

[0007] The residue content monitoring module analyzes the residue content inside the cleaning machine based on the transmitted setting parameters. It monitors the residue content by analyzing the cleaning water concentration within a given cycle and obtains monitoring information, including cycle count analysis signals and compliance signals. The cycle count analysis signals are transmitted to the cycle count adjustment analysis module, and the compliance signals are transmitted to the adjustment information output module. The specific monitoring method is as follows:

[0008] S1: First, obtain the preset number of cleaning cycles and denote it as n, where n = 1, 2, ..., m. Simultaneously, divide the preset number of cleaning cycles n into i groups of cycle periods, where i = 1, 2, ..., j. The resulting i groups of cycle periods are represented as single-group cycle periods. Perform segmentation. The specific value of the number of cycles in a single group is set by the operator, and the number of cleaning cycles corresponding to the generated i groups of cycle periods is the same and is an integer. Then, obtain the cycle period corresponding to the real-time number of cycles being half of the preset cleaning number of cycles, and record this cycle period as the period to be analyzed and denoted as k. Specifically, the period to be analyzed can be understood as that there is a position of the number of cycles within any cycle period that is half of the preset cleaning number of cycles. For example, if the cycle period is segmented into five groups, and when the number of cycles in the third group is half of the preset cleaning number of cycles, then the third group cycle period is marked as the period to be analyzed.

[0009] S2: Then obtain the cleaning water concentration corresponding to the period to be analyzed k and denote it as Nk. The cleaning water refers to the water introduced when using water to clean the cleaning tank, and the cleaning water concentration refers to the content of the mixture doped inside during the cleaning process. Then compare the cleaning water concentration Nk with the preset value Ny. The preset value Ny can be understood as the content of the residue corresponding to the standard production conditions. When Nk≥Ny, it means that the period to be analyzed does not meet the cleaning standard, and a cycle number analysis signal is generated. On the contrary, when Nk<Ny, it means that the period to be analyzed meets the cleaning standard, and a passing signal is generated.

[0010] Specifically, because there is a corresponding relationship between the two, normally if there are more residues in the cleaning machine, then the content of residues in the corresponding cleaning water will also be more. Along with the operation of the cleaning machine, the residues will slowly decrease, and the content of residues in the cleaning water will also decrease accordingly.

[0011] The cycle number adjustment analysis module is used to obtain the transmitted cycle number analysis signal, and judge whether it can complete the residue content detection and reach the standard within the preset cleaning number of cycles according to the remaining number of cycles, generate the corresponding passing signal and non-passing signal, then perform a secondary analysis on the non-passing signal to obtain the cycle number adjustment information, and transmit it to the adjustment information output module. The specific method of generating the cycle number adjustment information is as follows:

[0012] P1: Obtain the period to be analyzed k, and at the same time obtain the remaining cleaning number of cycles denoted as s. The remaining cleaning number of cycles is obtained by subtracting all the completed cleaning number of cycles from the preset cleaning number of cycles. The completed cleaning number of cycles is expressed as the total sum of the cleaning number of cycles corresponding to the period to be analyzed k and the cycle periods before it. Then obtain the cycle period before the period to be analyzed k and denote it as the completed period a, and a = 1, 2,..., b. At the same time, obtain the cleaning water concentration Na corresponding to the completed period a. Specifically, the cleaning water concentration corresponding to the completed period a is expressed as the cleaning water concentration obtained at the corresponding time point after the completion of the cycle number of this period.

[0013] P2: Calculate the cleaning efficiency corresponding to all completed cycles a, denoted as Xa. The cleaning efficiency is expressed as the ratio of the difference in cleaning water concentration to the number of cycles within the completed cycle. Then, calculate the average value of the cleaning efficiency Xa for all completed cycles a, denoted as the cleaning average value Xp, and use it as the overall cleaning standard efficiency. At the same time, substitute the cleaning standard efficiency Xp and the remaining cleaning cycles s into the formula Ns = Xp × s to calculate the cleaning concentration Ns corresponding to the remaining cleaning cycles.

[0014] P3: Next, substitute the cleaning concentrations Ns and Nk into the formula N1 = Nk - Ns to calculate the residue content N1 corresponding to the preset number of cleaning cycles. Then compare it with the preset value Ny. When N1 ≤ Ny, it means that the preset number of cleaning cycles can meet the cleaning standard and a compliance signal is generated. Conversely, when N1 > Ny, it means that the preset number of cleaning cycles cannot meet the cleaning standard and a non-compliance signal is generated.

[0015] P4: Calculate the difference between the residue content N1 corresponding to the preset number of cleaning cycles and the preset value Ny, denoted as the content difference Nc, and substitute it into the formula. The number of rotations h is calculated, where Nq is the concentration threshold, and the specific value is set by the operator. The concentration threshold Nq can be understood as expanding the overall concentration to a certain extent. At the same time, the number of rotations adjustment information is generated and transmitted to the adjustment information output module.

[0016] The adjustment information output module is used to acquire the transmission cycle adjustment information and the compliance signal, and display them to the operator through the display device.

[0017] This invention provides a cleaning cycle control system based on a cleaning machine. Compared with the prior art, it has the following advantages:

[0018] This invention determines the current residue content inside the cleaning tank based on the preset number of cleaning cycles of the cleaning machine. It monitors the residue content by dividing the cycle into periods of the same number of cycles, determining whether the residue content meets the standard at the current number of cleaning cycles. If it does not meet the standard, it analyzes the remaining number of cleaning cycles and whether the total preset number of cleaning cycles can achieve the required residue content. Furthermore, it adjusts the number of cleaning cycles for cases where the standard cannot be met. This allows for appropriate adjustments based on actual conditions, ensuring efficient and thorough cleaning of residues in the cleaning tank and ensuring that the residue content meets process requirements.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1 and Figure 2 This application provides a cleaning cycle control system based on a cleaning machine, including: a cleaning data acquisition module, a residue content monitoring module, a cycle number adjustment and analysis module, and an adjustment information output module.

[0023] The cleaning data acquisition module is used to acquire the parameters set by the cleaning machine, including the number of cleaning cycles initially set by the operator. These parameters are then transmitted to the residue content monitoring module.

[0024] The residue content monitoring module analyzes the residue content inside the cleaning machine based on the transmitted setting parameters. It monitors the residue content by analyzing the cleaning water concentration within a given cycle and obtains monitoring information, including cycle count analysis signals and compliance signals. The cycle count analysis signals are transmitted to the cycle count adjustment analysis module, and the compliance signals are transmitted to the adjustment information output module. The specific monitoring method is as follows:

[0025] S1: First, obtain the preset number of cleaning cycles and denote it as n, where n = 1, 2, ..., m. Simultaneously, divide the preset number of cleaning cycles n into i groups of cycle periods, where i = 1, 2, ..., j. The resulting i groups of cycle periods are represented as single-group cycle periods. The process involves segmentation, with the specific number of cycles per group set by the operator. All i-group cycles correspond to the same number of cleaning cycles, and these numbers are all integers. Next, the cycle corresponding to the real-time cycle count being half the preset cleaning cycle count is obtained and recorded as the analysis cycle, denoted as k. The analysis cycle can be understood as any cycle containing a cycle count that is half the preset cleaning cycle count. For example, if five cycles are generated after segmentation, and the third cycle contains half the preset cleaning cycle count, then the third cycle is marked as the analysis cycle.

[0026] S2: Next, obtain the concentration of the cleaning water corresponding to the analysis period k, denoted as Nk. The cleaning water refers to the water introduced when cleaning the cleaning tank with water, and the cleaning water concentration refers to the content of the mixture doped inside during the cleaning process. Then, compare the cleaning water concentration Nk with the preset value Ny. The preset value Ny can be understood as the residual content corresponding to the standard production conditions. When Nk≥Ny, it indicates that the analysis period does not meet the cleaning standard, and a lap number analysis signal is generated. On the contrary, when Nk<Ny, it indicates that the analysis period meets the cleaning standard, and a compliance signal is generated.

[0027] Specifically, due to the corresponding relationship between the two, under normal circumstances, if there are more residues in the cleaning machine, the content of residues in the corresponding cleaning water will also be more. As the cleaning machine works, the residues will slowly decrease, and the content of residues in the cleaning water will also decrease accordingly.

[0028] The lap number adjustment analysis module is used to obtain the transmitted lap number analysis signal, and judge whether the residue content detection can meet the standard within the preset cleaning lap number according to the remaining lap number, generate the corresponding compliance signal and non-compliance signal, then perform a secondary analysis on the non-compliance signal to obtain the lap number adjustment information, and transmit it to the adjustment information output module. The specific method of generating the lap number adjustment information is as follows:

[0029] P1: Obtain the analysis period k, and at the same time obtain the remaining cleaning lap number denoted as s. The remaining cleaning lap number is obtained by subtracting all the completed cleaning lap numbers from the preset cleaning lap number. The completed cleaning lap number is expressed as the total sum of the cleaning lap numbers corresponding to the lap number periods including the analysis period k and the previous ones. Then, obtain the lap number period before the analysis period k and denote it as the completed period a, where a = 1, 2, …, b. At the same time, obtain the cleaning water concentration Na corresponding to the completed period a. Specifically, the cleaning water concentration corresponding to the completed period a is expressed as the cleaning water concentration obtained at the corresponding time point after the completion of the lap number of this period.

[0030] P2: Calculate the cleaning efficiency corresponding to all completed periods a, denoted as Xa. The cleaning efficiency is expressed as the ratio of the change difference of the cleaning water concentration to the lap number within this completed period. Then, calculate the average value of the cleaning efficiencies Xa of all completed periods a, denoted as the cleaning average value Xp, and use it as the overall cleaning standard efficiency. At the same time, substitute the cleaning standard efficiency Xp and the remaining cleaning lap number s into the formula Ns = Xp×s to calculate the cleaning concentration Ns corresponding to the remaining cleaning lap number.

[0031] P3: Next, substitute the cleaning concentrations Ns and Nk into the formula N1 = Nk - Ns to calculate the residue content N1 corresponding to the preset number of cleaning cycles. Then compare it with the preset value Ny. When N1 ≤ Ny, it means that the preset number of cleaning cycles can meet the cleaning standard and a compliance signal is generated. Conversely, when N1 > Ny, it means that the preset number of cleaning cycles cannot meet the cleaning standard and a non-compliance signal is generated.

[0032] Based on actual analysis, the total residue content after the final preset number of cleaning cycles is calculated according to the remaining number of cycles. Then, the residue content is compared to determine whether the currently set preset number of cleaning cycles meets the standard. If it does, no further processing is required. If it does not meet the standard, the number of cleaning cycles needs to be adjusted. For example, if the residue content is 5% after the preset number of cleaning cycles is completed, while the production standard residue content is 3%, then the initially set preset number of cleaning cycles does not meet the standard and needs to be adjusted.

[0033] P4: Calculate the difference between the residue content N1 corresponding to the preset number of cleaning cycles and the preset value Ny, denoted as the content difference Nc, and substitute it into the formula. The number of rotations h is calculated, where Nq is the concentration threshold, and the specific value is set by the operator. The concentration threshold Nq can be understood as expanding the overall concentration to a certain extent. At the same time, the number of rotations adjustment information is generated and transmitted to the adjustment information output module.

[0034] The adjustment information output module is used to acquire the transmission cycle adjustment information and the compliance signal, and display them to the operator through the display device.

[0035] Specifically, the set number of cleaning cycles is transmitted to a designated data bit in the PLC via the touch screen, and a counter in the PLC is used to make the equipment perform cyclic cleaning according to the set number of cycles.

[0036] In the PLC program, an incrementing counter is used to enable the equipment to perform cyclic cleaning according to a set number of times. The number of cleaning cycles can be set on the touch screen and transmitted to the designated data bit of the PLC.

[0037] Example 2 is implemented based on Example 1, and the difference is that the real-time number of cycles obtained by the residue content detection module can be set to other values. In Example 1, the real-time number of cycles obtained is half of the preset number of cleaning cycles. In another analysis method, the real-time number of cycles can be selected as two-thirds of the preset number of cleaning cycles. The preset number of cleaning cycles can be analyzed by analyzing the cleaning water concentration corresponding to two-thirds of the real-time number of cycles. The subsequent analysis method is the same as the analysis method in Example 1.

[0038] Example 3 includes all implementation processes of Example 1 and Example 2.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
