Description

Technical Field

[0001] The present invention relates to the technical field of livestock breeding equipment, and particularly relates to a large-range multi-task free scheduling and conveying system and method for pig farms. Background Art

[0002] In traditional livestock breeding equipment, the process of feed conveying and distribution often relies on manual operation, which has problems of complex operation and low efficiency. Especially in large-scale farms, where the demand for feed is large and the tasks are numerous, traditional equipment and manual labor are difficult to handle efficiently. In addition, due to technical bottlenecks such as communication delays, the feed diversion three-way valve of the feed tower may be inaccurate when opening or closing, resulting in untimely feed distribution and affecting the breeding effect and economic benefits. Therefore, there is an urgent need for a discharging and conveying system that can be intelligently managed and precisely controlled to improve the efficiency and accuracy of feed conveying and distribution. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies in the above-mentioned existing background art, and provide a large-range multi-task free scheduling and conveying system and method for pig farms.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is: a large-range multi-task free scheduling and conveying system for pig farms, including a multi-task scheduling module, a task selection module, a conveying volume calculation module, a multi-level CPU control module, and a material line control module. Among them, the multi-task scheduling module automatically sorts according to the preset priority and task type; the task selection module is a user usage module, including the selection of the target feed tower, the main feed tower, and the setting of the conveyed feed volume; the conveying volume calculation module can automatically calculate the daily required scheduled feed volume according to the relevant parameters of the number of pigs, age, and feeding curve in the pigsty; the multi-level CPU control module includes a main control CPU cabinet and multiple sub-control CPU cabinets, which communicate with each other in coordination; the material line control module can intelligently control the start and stop sequence of the material line.

[0005] Further, the main control CPU cabinet in the multi-level CPU control module is arranged in the main feed tower, used to summarize the sub-control signals, and conduct unified deployment and judgment; multiple sub-control CPU cabinets are arranged in multiple sub-feed towers, which can transmit signal communication to the main control CPU and can also independently control the sub-feed towers.

[0006] Further, the communication between the sub-control CPU and the main control CPU uses a ring redundant topology optical fiber as the carrier, and the communication protocol is the standard Siemens PROFINET network protocol, including the isochronous real-time mode and the synchronous clock. Among them, the cycle time in the isochronous real-time mode is set to 1 ms - 2 ms; the accuracy in the synchronous clock is ≤ 500 ns, and the IEEE 1588v2 protocol is adopted. Among them, the main control CPU cabinet is the PTP master clock, the sub-control CPU cabinet is the slave clock, and the clocks of multiple sub-control CPUs are synchronized.

[0007] In the technical solution of the present invention, a method for free scheduling and conveying of multi-tasks in a large-scale pig farm is also provided. Based on the above-mentioned system for free scheduling and conveying of multi-tasks in a large-scale pig farm, it includes the following steps:

[0008] S1. The system starts, and sequential task judgments are made in accordance with the order displayed on the system interface in the task selection module. In task 1, it is judged whether there is a target distribution tower in the distribution tower selection. If so, it continues to judge whether there is a target main material tower in the main material tower selection. If so, it continues to judge whether there is a weight in the conveyed material quantity. If so, it indicates that the target material tower is empty and executes the discharging task; if any of the above judgments is negative, all continue to judge the above judgment items in task 2 by adding 1 to the sorted tasks;

[0009] S2. After the discharging task is started, the level sensor detects whether there is a fault. If not, it notifies the sub-control CPU cabinet to execute the discharging task, and the blanking three-way valve in the target distribution tower is opened. At this time, there is an opening delay for the blanking three-way valve in the target distribution tower. If it is not opened in place, it continues to run and open. When the opening times out, the entire system stops; after the blanking three-way valve in the target distribution tower is opened in place, the material line control module controls the material line to start in a sequential delayed reverse order, and the main material tower distribution motor starts to discharge;

[0010] S3. The conveying quantity calculation module measures the discharging quantity in real time and compares it with the preset conveying material quantity in the corresponding task serial number. If the preset value is reached, the main material tower distribution motor is turned off, the material line stops in a sequential delayed forward order, and the blanking three-way valve corresponding to the target distribution tower is closed; if the preset value is not reached, continuous discharging is carried out for measurement comparison;

[0011] S4. There is a closing delay for the blanking three-way valve in the above steps. If it times out, the entire system stops; if all are closed in place, it returns to the system judgment of adding 1 to the task, and continues to perform the task of the next serial number until the maximum task number is exceeded, then the system ends.

[0012] Further, the calculation formula for the preset individual discharging quantity in step S3 by the conveying quantity calculation module is:

[0013]

[0014] Among them, Mn is the total feeding and transportation volume of a single target feed tower; Dn is the daily age of pigs in a certain unit; Nn is the number of pigs in a certain unit; Cn is the feeding curve of pig types, and pig types include nursery pigs, fattening pigs, sows, boars, and replacement gilts.

[0015] Further, in step S3, the feed lines stop in ascending order with progressive delays. Among them,

[0016] The dynamic calculation formula for the cleaning delay of a single feed line is:

[0017] The calculation formula for the cleaning delay of the main feed line is:

[0018] Among them, T cycle : is the delay time of a single feed line; Lx is the length of the feed line; RPM is the rated speed of the motor; N is the reduction ratio of the reducer: Rd is the radius of the drive disk; K is the dynamic adjustment coefficient of the feed line length.

[0019] Further, the above-mentioned dynamic adjustment coefficient K of the feed line length is 1.2.

[0020] Further, the maximum number of tasks in step S4 is the number of tasks selected on the user system interface in the task selection module.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Efficient multi-task management: Through the multi-task scheduling module, the system can efficiently process multiple discharging and conveying tasks, significantly improving the efficiency of feed conveying and distribution; the system management is intelligent, greatly reducing manual intervention and improving the overall work efficiency.

[0023] 2. Flexible task selection: The task selection module provides various options such as feed tower selection, main feed tower selection, and setting of conveying feed volume, greatly enhancing the adaptability and flexibility of the system; users can flexibly adjust tasks according to actual breeding needs to meet the usage requirements of different scenarios.

[0024] 3. Precise feed calculation: The conveying volume calculation module can scientifically calculate the daily required scheduled feed volume according to the specific situation of pigs, ensuring the accuracy and rationality of feed supply, avoiding waste; the accuracy of the calculation results can meet the breeding needs of large-scale and high-efficiency, providing a guarantee for the economic benefits of the breeding industry.

[0025] 4. Stable control system: The control module adopting the multi-CPU mode effectively solves the communication delay problem, ensures the accurate positioning when the three-way valve of the feeding tower is opened or closed, and improves the stability and reliability of the system. Compared with the communication delays of traditional RS485 and Profinet optical fiber, the delay is reduced from the original 1 s to 20 us, and the blockage rate is decreased by 30%.

[0026] 5. The intelligent adjustment of the start and stop sequence of the material line control module realizes efficient and energy-saving conveying. Compared with the traditional feeding energy consumption, the energy consumption is saved by 30%, and the service life of the equipment is increased by 1 - 2 years. Brief Description of the Drawings

[0032] The following will further elaborate on the detailed embodiments of the present invention in conjunction with the drawings:

[0033] As Figure 1 shown, a large-scale pig farm multi-task free scheduling conveying system includes a multi-task scheduling module, a task selection module, a conveying volume calculation module, a multi-level CPU control module, and a material line control module. The multi-task scheduling module can automatically sort according to the preset task priorities and task types, and can perform intelligent jumps in sequence among the sorted tasks. The task selection module is a user usage module, including the selection of the target feeding tower, the main feeding tower, and the setting of the conveying material volume. Users can input and select through the user system interface. This flexibility enables the system to adapt to the requirements of different breeding scenarios and meet diverse operation needs. The conveying volume calculation module can comprehensively calculate based on the specific situation of the pigs in the pigsty, such as the number of pigs, the age, and the relevant parameters of the feeding curve, and automatically calculate the daily required scheduled feed volume to ensure the scientificity and rationality of the feed supply. Combined with Figure 4As shown in the figure, the multi-level CPU control module includes a main control CPU cabinet and multiple sub-control CPU cabinets, which communicate with each other in a coordinated manner. The main control CPU cabinet is set in the main material tower and is used to summarize the sub-control signals for unified deployment and judgment. The multiple sub-control CPU cabinets are set in multiple sub-material towers and can transmit signal communication to the main control CPU, and can also independently control the sub-material towers. The above sub-control CPU and the main control CPU cooperate to control, and the communication between the two uses a ring redundant topology optical fiber as the carrier, and the network can automatically switch paths to ensure the uninterrupted operation of the system. The communication protocol is the standard Siemens PROFINET network protocol, including an isochronous real-time mode and a synchronous clock. In the isochronous real-time mode, the cycle time is set to 1ms - 2ms to balance real-time performance and system load for precise timing control of the three-way valve of the sub-material tower (such as reverse start / stop). In the synchronous clock, the clock synchronization accuracy ≤ 500ns, and the IEEE1588v2 protocol is used. The main control CPU cabinet is the PTP master clock, and the sub-control CPU cabinets are slave clocks, and the clocks of multiple sub-control CPUs are synchronized to avoid timing deviations in task execution. This design can effectively solve the problem of the three-way valve of the sub-material tower not being in place due to communication delay when opening or closing, ensuring the accuracy and stability of feed distribution. The material line control module can intelligently control the start and stop sequence of the material line. As Figure 5 shown, the material lines 1 to 4 are connected in sequence according to the serial number. In the start-up stage, they are started sequentially with a reverse order and a time delay. The material line 4 runs first, and there is a time delay T0 for starting between two adjacent material lines to avoid material blockage. When cleaning the material, they are stopped sequentially with a forward order and a time delay. The material line 1 stops running first, and stops at intervals of T1, T2, T3, and T4 in sequence to avoid the long-term idling of the material line motor and reduce power waste, realizing efficient and energy-saving transportation. This module can also intelligently adjust the start and stop sequence according to factors such as the length of the material line and the conveying speed to further optimize the transportation process.

[0034] In the technical solution of the present invention, a large-scale pig farm multi-task free scheduling and transportation method is also provided. Based on the above-mentioned large-scale pig farm multi-task free scheduling and transportation system, it includes the following steps. Combining Figure 2 and Figure 3 shown,

[0035] S1. The system starts. First, it makes task judgments in the order of the task numbers displayed on the user system interface in the task selection module. The first item is to determine whether there is a target distribution tower in Task 1. If so, it continues to judge the second item, whether there is a target main tower. If so, it continues to judge the third item in this Task 1, whether there is a weight in the conveying material quantity grid. If so, it indicates that the target tower is empty and executes the discharging task. If any of the above sequential judgments is negative, it continues to judge each of the above judgment items in Task No. 2 by adding one to the sorted task. For example, if the distribution tower selected in No. 1 is Distribution Tower 651, the main tower selected is sow feed, and the conveying material quantity is 999 kg, the system first runs the conveying material task in No. 1. After the conveying task in No. 1 is completed, it judges No. 2. If the distribution tower selected in No. 2 is Distribution Tower 651 and no main tower is selected in the main tower selection, it stops the conveying task in No. 2 and then intelligently jumps to No. 3 for task judgment, and so on;

[0036] S2. After the discharging task is started, the level sensor detects whether there is a fault. If not, it notifies the sub-control CPU cabinet to execute the discharging task, and the material dropping three-way valve in the target distribution tower is opened. At this time, there is an opening delay for the material dropping three-way valve in the target distribution tower. If it is not opened in place, it continues to run and open. When the opening times out, the entire system stops. After the material dropping three-way valve in the above target distribution tower is opened in place, the material line control module controls the material line to start in a delayed reverse order step by step, and the main tower distribution motor starts to discharge;

[0037] S3. The conveying quantity calculation module measures the discharging quantity in real time and compares it with the preset conveying material quantity in the corresponding task number. If the preset value is reached, the above main tower distribution motor is turned off, and the material line stops in a delayed forward order step by step to prevent blockage, and the material dropping three-way valve corresponding to the above target distribution tower is closed. If the preset value is not reached, it continues to discharge for measurement and comparison;

[0038] S4. There is a closing delay for the material dropping three-way valve in the above step S3. If it times out, the entire system stops. If all are closed in place, it returns to the system judgment of adding one to the task and continues to perform the task of the next number, and so on, until it exceeds the maximum number of tasks (the maximum number of tasks here is the number of tasks selected on the user system interface in the task selection module), then the system ends.

[0039] Further, the formula preset by the conveying quantity calculation module in the above step S3 for calculating the individual discharging quantity is:

[0040]

[0041] Among them, Mn: is the total feeding and transportation quantity of a single target tower; Dn: is the daily age of pigs in a certain unit; Nn: is the number of pigs in a certain unit; Cn: is the feeding curve of pig types, and pig types include nursery pigs, fattening pigs, sows, boars, and replacement gilts.

[0042] In step S3 above, the material lines stop in positive sequence with step-by-step delay. Among them,

[0043] The dynamic calculation formula for the cleaning delay of a single material line is:

[0044] The calculation formula for the cleaning delay of the total material line is:

[0045] Among them, T cycle : is the delay time of a single material line; Lx: is the length of the material line; RPM: is the rated speed of the motor; N: is the reduction ratio of the reducer: Rd: is the radius of the drive disk; K: is the dynamic adjustment coefficient of the material line length. The dynamic adjustment coefficient K of the material line length is 1.2, and it can be obtained according to actual operation tests and is affected by factors such as pipeline friction and gear transmission.

[0046] Example 1,

[0047] Comparison of the total feeding transportation volume Mn of a single building with multiple units of the target feed tower,

[0048] Parameter setting,

[0049] Type of pigs:

[0050] The single-head feeding volume C1 of nursery pigs on the 30th day = 0.5 kg; the single-head feeding volume C2 of finishing pigs on the 90th day = 1.5 kg;

[0051] Unit and number of pigs:

[0052] 5 units of nursery pigs; 5 units of finishing pigs;

[0053] For each unit of nursery pigs: the age D1 = 30 days, and the number N1 = 800 heads;

[0054] For each unit of finishing pigs: the age D2 = 90 days, and the number N2 = 200 heads;

[0055] Combining the above parameter data, calculate using the conventional mode:

[0056] The conventional method mostly uses a fixed daily average feeding volume (assuming that each pig needs 2 kg of feed per day),

[0057] The total feeding transportation volume Mn = (800 + 200) * 2 * 5 = 10000 kg;

[0058] Combining the above parameter data, calculate using the calculation formula for presetting the individual discharge volume of the above transportation volume calculation module:

[0059]

[0060] - The feed volume of a unit of nursery pigs = 800 * 0.5 = 400 kg;

[0061] - The feed amount for single - unit fattening pigs = 200 * 1.5 = 300 kg;

[0062] - The total feeding and transportation amount Mn = 400 * 5 + 300 * 5 = 2000 + 1500 = 3500 kg.

[0063] Comparing the results of the above two calculation methods, the conventional mode does not consider the differences in pig age and feeding curves and still distributes by a fixed amount, which may lead to feed waste or insufficiency; the scientific calculation using the above - mentioned transportation amount calculation module can accurately match the needs of different pigs, reasonably plan the feed feeding amount (for example, the actual demand of nursery pigs is much lower than that of fattening pigs), and avoid waste.

[0064] Example 2,

[0065] The cleaning delay time T of a single feed line cycle Comparison,

[0066] Parameter setting,

[0067] - The length of the feed line L x = 50 m;

[0068] - The rated speed of the motor RPM = 1500 r / min;

[0069] - The reduction ratio N of the reducer = 31.4;

[0070] - The radius R of the drive disk d = 0.1 m;

[0071] - The dynamic adjustment coefficient K = 1.2.

[0072] Combined with the above - mentioned parameter setting, calculate using the conventional mode:

[0073] The conventional method mostly uses a fixed delay time (assuming a fixed delay of 3 seconds per meter of the feed line),

[0074] The cleaning time T of a single feed line 常规 = 50 * 3 = 150 seconds;

[0075] Combined with the above - mentioned parameter setting, calculate using the dynamic calculation formula for the cleaning delay of a single feed line in the above - mentioned transportation amount calculation module:

[0076]

[0077] - Substitute the parameters:

[0078] T cycle = (50 * 1.2) / (1500 / 31.4 * 2 * 3.14 * 0.1)= 60 / 30 = 2 minutes = 120 seconds.

[0079] Comparing the results of the above two calculation methods, in the conventional mode, since dynamic factors such as motor speed and reduction ratio are not considered, the required material cleaning time is significantly longer (150 seconds vs 120 seconds); while using the above dynamic calculation formula for single material line cleaning delay, it can combine the above dynamic factors and greatly shorten the material cleaning time, reduce energy consumption and equipment wear through dynamic adjustment.

[0080] In summary, the present invention can be significantly superior to the conventional mode in feed quantity calculation and material cleaning time optimization through scientific formulas and intelligent control, achieving precise feeding (avoiding waste) and high energy efficiency (reducing energy consumption by more than 30%).

[0081] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
