Description

Technical Field

[0001] The present invention relates to the technical field, and in particular, to a steel plate granary clearing control method, granary, system and storage medium. Background Art

[0002] In the field of modern grain storage, steel plate granaries are widely used for long-term storage of grain due to their sturdy structure and good sealing.

[0003] During the grain storage process in steel silos, due to the friction and compression between grain particles, some grain often adheres to the silo wall, forming residues that are difficult to clean. These attached grains not only reduce the effective storage space of the silo, but also may become corrupt due to changes in humidity and temperature over time, further affecting food security. The traditional method of clearing the silo relies on manual entry into the silo for cleaning, but the silo is poorly ventilated and the temperature is high, making it difficult to clean the silo. If personnel go down to the silo to clean the remaining grain without paying attention to ventilation, there are safety hazards; in addition, manual cleaning is not only inefficient and costly, but also poses a threat to the health and safety of operators. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a steel plate granary clearing control method.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0006] A method for controlling the clearing of a steel plate grain silo comprises the following steps: S1, detecting whether the grain silo is in an empty state; S2, if the grain silo is in an empty state, detecting and obtaining the grain area attached to the silo wall, and judging whether the grain area attached to the silo wall is greater than a first preset threshold; S3, if so, starting a silo wall vibrator to work until the grain area attached to the silo wall is less than or equal to the first preset threshold or the vibrator works for a longer time than a preset time.

[0007] Furthermore, in step S3, when the silo wall vibrator is started, if the silo wall vibrator is working for the first N times, the silo wall vibrator continuously adjusts the vibration frequency of the silo wall vibrator to increase the rate of decrease of the grain area attached to the silo wall until the grain area attached to the silo wall is less than the second set threshold value, and the vibration frequency corresponding to the fastest rate of decrease of the grain area attached to the silo wall during the working period of the silo wall vibrator is used as the preferred vibration frequency, and the preferred vibration frequency f is adjusted after each work for the first N times. 优 Update, and the updated preferred vibration frequency f 优 As the initial frequency for starting the next working bin wall vibrator.

[0008] Further, when the warehouse wall vibrator is not working for the first N times, the warehouse wall vibrator works according to the following steps: S31, when the warehouse wall vibrator works for the G+1th time, the initial frequency f of the warehouse wall vibrator is G+1 is: f G+1 =f 优 -f 间 +f 步 , and record the working time t G+1 ; The initial value of G is N, f 步 The initial value is 0;

[0009] S32, when the silo wall vibrator works for G+2 times, the initial frequency f of the silo wall vibrator G+2 is: f G+2 =f 优 +f 步 , and record the working time t G+2 ;

[0010] S33, when the silo wall vibrator works for the G+3th time, the initial frequency f of the silo wall vibrator G+3 is: f G+3 =f 优 +f 间 +f 步 , and record the working time t G+3 ;

[0011] S34, comparing the working time of steps S31, S32 and S33:

[0012] S341, if t G+2 If the time is the shortest, f 间 Update to f 间 =f 间 / 2, determine the updated f 间 Is it less than the second preset threshold: If so, the subsequent working frequency of the warehouse wall vibrator is maintained at f G+2 ;

[0013] If not, update the G value: G=G+3, and return to step S31;

[0014] S342, if t G+1 If the time is the shortest, update f 步 value, so that f 步 =f 步 -f 间 , update the G value to make G=G+3, and return to step S31;

[0015] S343, if t G+3 If the time is the shortest, update f 步 value, so that f 步 =f 步 +f 间, update the G value to make G=G+3, and return to step S31.

[0016] Furthermore, the operating frequency of the subsequent bin wall vibrator is maintained at f G+2 , and then further includes the step: S35, continuously monitoring the working time t of each working of the warehouse wall vibrator i , judge t i Whether it satisfies the formula: t i >γt G+2 : If so, execute step S36; S36, determine whether the number of times step S36 has been executed is greater than the third preset threshold: if so, issue a grain silo assembly warning message; if not, update the G value to make G=G+3, and return to step S31.

[0017] Furthermore, the detecting and obtaining of the grain area attached to the warehouse wall specifically includes:

[0018] The silo wall is photographed by video equipment to obtain an image of the silo wall, which is then compared with the image of a clean silo wall to obtain the area of ​​grain attached to the silo wall.

[0019] Furthermore, step S3 also includes sending a manual clearance message if the vibrator working time is greater than a preset time.

[0020] Furthermore, a plurality of silo wall vibrators are arranged around the bottom wall of the silo.

[0021] The present invention also proposes a granary, comprising: a silo body; an empty silo detection mechanism for detecting whether the granary is in an empty silo state; an area detection mechanism for detecting the area of ​​grain attached to the silo wall; and a silo wall vibrator for starting operation when the area of ​​grain attached to the silo wall is greater than a first preset threshold value, until the area of ​​grain attached to the silo wall is less than or equal to the first preset threshold value or the operating time is greater than a preset time.

[0022] The present invention also proposes a steel plate grain silo clearing control system, comprising: an empty silo status receiving module, used to receive empty silo status information, the empty silo status information is sent when an empty silo detection mechanism detects that the grain silo is in an empty silo status; an area receiving module, used to receive grain area information, the grain area information is sent by an area detection mechanism; a judgment module, used to judge whether the grain area attached to the silo wall is greater than a first preset threshold; a silo wall vibrator control module, used to control the operation of the silo wall vibrator.

[0023] The present invention also proposes a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor, the steps of the steel plate granary clearing control method are implemented.

[0024] The present invention has the following beneficial effects:

[0025] By automatically detecting the empty state of the granary and the area of ​​grain attached to the granary wall, and intelligently starting the granary wall vibrator according to the preset threshold, manual intervention is reduced, and the efficiency of the warehouse cleaning operation is greatly improved; the automated warehouse cleaning method reduces the reliance on manual cleaning, thereby reducing labor costs, and avoids personnel directly entering the granary to perform warehouse cleaning operations, thereby reducing health and safety risks caused by environmental factors such as poor ventilation and high temperature, and ensuring the life safety of operators. Through the intelligent control of preset thresholds and vibrator working hours, precise management of the warehouse cleaning process is achieved, ensuring the warehouse cleaning effect while avoiding damage to the granary structure caused by excessive vibration.

[0035] Please refer to Figure 2 A method for controlling the clearing of a steel plate granary in a preferred embodiment of the present invention comprises the following steps S1, S2 and S3.

[0036] S1, detect whether the granary is empty, such as Figure 1 As shown, an empty bin detection mechanism 200 can be usually provided at the bottom of the granary to detect whether the granary is in an empty bin state. The empty bin detection mechanism 200 can be a material level meter. If the granary is not in an empty bin state, there is no need to start the bin clearing work.

[0037] S2: If the granary is in an empty state, detect and obtain the area of ​​grain attached to the granary wall, and determine whether the area of ​​grain attached to the granary wall is greater than a first preset threshold.

[0038] S3, if the area of ​​grain attached to the warehouse wall is greater than the first preset threshold, the warehouse wall vibrator is started to work until the area of ​​grain attached to the warehouse wall is less than or equal to the first preset threshold or the vibrator works for a longer time than the preset time. If one of the two conditions, that the area of ​​grain attached to the warehouse wall is less than or equal to the first preset threshold and the vibrator works for a longer time than the preset time, is met, the warehouse wall vibrator needs to stop working. The first preset threshold can be adjusted according to the actual situation. If the warehouse wall is relatively clean and smooth, and the warehouse clearing effect after vibration is very good, the first preset threshold can be set to zero or a value close to zero, such as 0.1 square meters, which means that there are no obvious large pieces of attachments on the warehouse wall. If the area of ​​grain attached to the warehouse wall is not greater than the first preset threshold, there is no need to clear the warehouse and no need to start.

[0039] The present invention provides a steel plate grain silo clearing control method, which automatically detects the empty state of the silo and the area of ​​grain attached to the silo wall, and intelligently starts the silo wall vibrator according to the preset threshold value, thereby reducing manual intervention and greatly improving the efficiency of the clearing operation; the automated clearing method reduces the reliance on manual cleaning, thereby reducing labor costs, and avoids personnel directly entering the silo to perform clearing operations, thereby reducing health and safety risks caused by environmental factors such as poor ventilation and high temperature, and ensuring the life safety of operators. Through the intelligent control of the preset threshold value and the working time of the vibrator, the precise management of the clearing process is achieved, which ensures the clearing effect while avoiding the damage to the silo structure caused by excessive vibration.

[0040] In some embodiments of the present invention, in step S3, when the silo wall vibrator is started, if the silo wall vibrator is working for the first N times, the silo wall vibrator continuously adjusts the vibration frequency of the silo wall vibrator to increase the rate of decrease of the grain area attached to the silo wall until the grain area attached to the silo wall is less than the second set threshold value, and the vibration frequency corresponding to the fastest rate of decrease of the grain area attached to the silo wall during the working period of the silo wall vibrator is used as the preferred vibration frequency f 优 , and during the first N times of work, the optimal vibration frequency will be updated after each work. That is, after each work, the vibration frequency corresponding to the fastest reduction rate of the grain area attached to the silo wall during this work period will be analyzed and obtained as the latest optimal vibration frequency f 优 , and the updated preferred vibration frequency f 优 As the initial frequency for starting the warehouse wall vibrator for the next work, of course, the initial frequency when the warehouse wall vibrator is started for the first time needs to be preset, which can be preset based on manual and past experience. It can be understood that in the process of adjusting the vibration frequency of the warehouse wall vibrator, the change in vibration frequency is based on the vibration frequency of the previous moment, rather than a discrete and large change, but a continuous change. The vibration frequency of the warehouse wall vibrator is continuously adjusted during the first N times of work, and the optimal vibration frequency is obtained after each work, thereby obtaining a vibration frequency of the warehouse wall vibrator with increasingly higher clearance efficiency. Due to the large frequency range in the early stage, the vibration frequency of the warehouse wall vibrator is constantly changing during the first N times of warehouse clearance work, so as to seek a better optimal vibration frequency, providing a better foundation for subsequent precise frequency adjustment.

[0041] Reference Figure 3 In a further embodiment of the present invention, when the warehouse wall vibrator is not working as in the previous N times, the warehouse wall vibrator works according to steps S31, S32, S33 and S34.

[0042] S31, the initial frequency f of the silo wall vibrator when the silo wall vibrator works for the G+1th time G+1 is: f G+1 =f优 -f 间 +f 步 , and record the working time t G+1 ; The initial value of G is N, f 步 The initial value is 0; f 优 That is, the optimal vibration frequency f obtained during the Nth operation 优 .

[0043] S32, when the silo wall vibrator works for G+2 times, the initial frequency f of the silo wall vibrator G+2 is: f G+2 =f 优 +f 步 , and record the working time t G+2 .

[0044] S33, when the silo wall vibrator works for the G+3th time, the initial frequency f of the silo wall vibrator G+3 is: f G+3 =f 优 +f 间 +f 步 , and record the working time t G+3 .

[0045] Since the operating frequency of step S31 is at f 优 Nearby, it is already the preferred frequency, usually the clearance time will be much shorter than the preset duration, and will not trigger the vibrator to work for longer than the preset duration and stop working midway. 优 is the optimal working frequency, which is already within the optimal frequency range, so we can try to approach the optimal working frequency through repeated work. In addition, since the optimal vibration frequency f obtained in the first N times of work 优 It is selected from the continuously changing vibration frequencies in a single operation, and will be disturbed and affected by the previous and next frequencies and the working time, so that the preferred vibration frequency f is directly adopted. 优 It is not accurate to use it as the optimal working frequency. For example, during a single warehouse cleaning operation, the vibration frequency of the warehouse wall vibrator is changing. When a large area of ​​grain attachments falls, the frequency at this time will be determined as the optimal vibration frequency f. 优 However, since the silo wall vibrator may have been working for a period of time, the attachments have been loosened under vibrations of other frequencies, and just at the preferred vibration frequency f 优 The large-scale shedding during this working period does not mean that a large area of ​​food attachments fall off completely. The optimal vibration frequency f 优 The effect may be caused by the vibration of other working frequencies of the silo wall vibrator and after a period of working time, so the preferred vibration frequency f is directly used. 优It is not accurate to use it as the best working frequency. However, the single working frequency of steps S31, S32 and S33 is fixed, which can eliminate the interference and influence caused by the operation of other working frequencies and the accumulation of working time, providing strong support for selecting the best working frequency.

[0046] S34, comparing the working time of steps S31, S32 and S33:

[0047] S341, if steps S31, S32 and S33 are G+2 If the time is the shortest, f 间 Update to f 间 =f 间 / 2, determine the updated f 间 Is it less than the second preset threshold: If so, the subsequent working frequency of the warehouse wall vibrator is maintained at f G+2 , which means the updated f 间 is less than the second preset threshold value, the range of the optimal selection of the working frequency of the warehouse wall vibrator has converged to a certain extent, and there is no need to test and select the working frequency. The current working frequency f G+2 If not, the G value is updated: G = G + 3, and the process returns to step S31, indicating that the updated f 间 Not less than the second preset threshold value indicates that there is still a certain range for further optimization and selection to determine a better working frequency to improve the clearance efficiency.

[0048] S342, if steps S31, S32 and S33 are G+1 If the time is the shortest, update f 步 value, so that f 步 =f 步 -f 间 , that is, the updated f 步 It is in the original 步 Subtract f from the value 间 After returning to steps S31, S32 and S33, the operating frequencies of the three steps are all reduced by one f. 间 , so that the overall operating frequency retreats, that is, to a lower operating frequency range for trial verification, to a lower operating frequency range for trial verification, t G+1 The shortest time means f G+1 is closer to the optimal frequency, and from the trend, t G+3 ,t G+2 and t G+1 Time is gradually reduced, f G+3 、f G+2 and f G+1The frequency is gradually reduced, so it is necessary to continue to reduce the working frequency to get closer to the optimal working frequency. When returning to step S31, it is also necessary to update the G value so that G=G+3, that is, the G value is increased by 3 on the original basis.

[0049] S343, if t G+3 If the time is the shortest, update f 步 value, so that f 步 =f 步 +f 间 , update the G value to make G=G+3, and return to step S31. That is, the updated f 步 It is in the original 步 Add f to the value 间 After returning to steps S31, S32 and S33, the operating frequencies of the three steps are increased by one f 间 , so that the value of the overall operating frequency is pushed forward, that is, to a higher operating frequency range for trial verification, to verify the higher operating frequency, t G+3 The shortest time means f G+3 It is closer to the optimal frequency, and from the trend, it is necessary to continue to increase the operating frequency to get closer to the optimal operating frequency. When returning to step S31, it is also necessary to update the G value so that G=G+3, that is, the G value is increased by 3 on the original basis.

[0050] Through multiple cycles, S341 can be executed multiple times to 间 After the optimal operating frequency can be selected within a smaller range, the selected operating frequency can be further verified and the final f can be directly used. G+2 As the best operating frequency, it is sufficient to ensure a high clearance efficiency. There is no need to pursue the superiority of the operating frequency to an extreme extent.

[0051] In a further embodiment of the present invention, the operating frequency of the subsequent bin wall vibrator is maintained at f G+2 , followed by the steps:

[0052] S35, continuously monitor the working time t of the silo wall vibrator each time i , judge t i Whether it satisfies the formula: t i >γt G+2 : If yes, execute step S36. i represents the working time of the warehouse wall vibrator in the i-th warehouse cleaning operation. If not, the subsequent working frequency of the warehouse wall vibrator continues to maintain f G+2 .

[0053] S36, determine whether the number of times step S36 has been executed is greater than the third preset threshold: if so, issue a grain silo assembly warning message; if not, update the G value to make G=G+3, and return to step S31. That is, when step S36 is executed for the fifth time, the number of times step S36 has been executed is four.

[0054] The ideal working hours should be t G+2 However, as the working time of the granary increases, the assembly of its various parts may become loose, which will result in the actual working time t i >γt G+2 When this happens, it is necessary to return to step S31 to find the best working frequency again. In addition, the main purpose of executing step S36 is that when step S36 is executed multiple times, it means that the looseness between the grain silo components may gradually increase. At this time, the grain silo assembly warning information is issued to remind the maintenance personnel to maintain the grain silo. It can be understood that after the grain silo is maintained, it can be understood as a brand new grain silo, so steps S1, S2 and S3 need to be re-executed.

[0055] In a further embodiment of the present invention, detecting and obtaining the area of ​​grain attached to the warehouse wall specifically includes: photographing the warehouse wall with a camera device to obtain an image of the warehouse wall, and comparing the image with the image of a clean warehouse wall. The area where the grain is attached can be clearly distinguished through the comparison, and the total area of ​​grain attached to the warehouse wall can be obtained by superimposing the areas of these areas, thereby identifying the grain attachment area through image recognition technology to achieve intelligent detection.

[0056] In a further embodiment of the present invention, step S3 further includes, if the working time of the vibrator is greater than a preset time, sending a manual clearance message to remind that the vibrator can no longer completely clear the warehouse and manual auxiliary clearance is required.

[0057] In a further embodiment of the present invention, a plurality of silo wall vibrators are arranged around the bottom wall of the silo to achieve multi-position vibration, thereby further improving the efficiency and effect of silo cleaning.

[0058] Reference Figure 1 The present invention also proposes a granary, including: a silo body 100; an empty silo detection mechanism 200, used to detect whether the silo is in an empty silo state; an area detection mechanism, used to detect the area of ​​grain attached to the silo wall, the area detection mechanism can be a camera with an image recognition system, the camera can be installed on the inner silo wall of the silo body 100 or on the top of the silo body 100, and multiple cameras can be set to achieve full coverage of the camera; a silo wall vibrator 300, used to start working when the area of ​​grain attached to the silo wall is greater than a first preset threshold value, until the area of ​​grain attached to the silo wall is less than or equal to the first preset threshold value or the working time is greater than the preset time.

[0059] The present invention also proposes a steel plate grain silo clearing control system, comprising: an empty silo status receiving module, used to receive empty silo status information, the empty silo status information is sent when the empty silo detection mechanism 200 detects that the granary is in an empty silo status; an area receiving module, used to receive grain area information, the grain area information is sent by the area detection mechanism; a judgment module, used to judge whether the grain area attached to the silo wall is greater than a first preset threshold; a silo wall vibrator control module, used to control the silo wall vibrator to start working when the grain area attached to the silo wall is greater than the first preset threshold, until the grain area attached to the silo wall is less than or equal to the first preset threshold or the working time is greater than the preset time.
