Description

Technical Field

[0001] The present application relates to the technical field of cottonseed pretreatment, and in particular to an automatic control system and method for cottonseed pretreatment. Background Art

[0002] At present, in the field of cotton processing machinery, the control of the cottonseed pretreatment system is only a simple electrical control of a single processing machine. There are multiple processing machines in the cottonseed pretreatment system in the factory. Each machine requires an operator to start and stop it separately. The feeding process between the machines is prone to abnormal errors. When a machine has a problem, the operator needs to brake and stop it urgently. When a machine in the middle of the process stops, the machines before and after may also fail, increasing the mechanical failure rate.

[0003] During the operation of the existing cottonseed pretreatment system, due to the uncertain feed amount and different conveyor speeds, the feeding frequency needs to be manually adjusted to avoid malfunctions. When the conveying equipment is running, human eyes are needed to observe the operating status of the equipment. It is impossible to directly determine whether the conveying equipment has a fault and the cause of the fault. When a problem occurs in a processing machine during the pretreatment process, the staff is required to suspend the machine, which will also affect the operation of other machines, not only wasting manpower but also reducing production efficiency. Summary of the invention

[0004] In order to solve the above problems, the present application provides a cottonseed pretreatment automatic control system and method to solve the problem that too much manpower is wasted in operating the processing machinery in the current cottonseed pretreatment process, and the cause of the failure cannot be determined when the conveying equipment fails. The system includes:

[0005] An acquisition module is used to acquire the cottonseed data to be processed in real time;

[0006] An automatic metering module is used to control the feeding amount of cotton seeds, and the automatic metering module feeds the cotton seeds uniformly and quantitatively;

[0007] A frequency conversion module is provided on the feeder, and the frequency conversion module is used to adjust the feeding frequency of the feeder;

[0008] A speed detection module is provided on the conveyor, and is used to monitor the real-time running speed of the conveyor during the conveying process and send the speed to the control module;

[0009] The control module is used to receive the real-time running speed sent by the speed detection module. The control module determines whether the conveyor fails and the cause of the failure based on the running speed when the conveyor fails in history. The acquisition module, the automatic metering module, the frequency conversion module, the speed detection module, and the control module are electrically connected.

[0010] In some embodiments of the present application, a cottonseed pretreatment automatic control system further includes:

[0011] The material level alarm module is arranged on each hopper and is used to detect the material level in the hopper and send a corresponding alarm signal when the material level is too high or too low. The material level alarm module is electrically connected to the control module.

[0012] In some embodiments of the present application, a cottonseed pretreatment automatic control system further includes:

[0013] a detection module, for detecting the cotton kernel content and the cotton husk content after the initial husking, and obtaining qualified cotton husks, qualified cotton kernels, unqualified cotton husks, and unqualified cotton kernels, wherein the cotton kernel content in the qualified cotton husks is lower than a first preset value, the cotton husk content in the qualified cotton kernels is lower than a second preset value, the cotton kernel content in the unqualified cotton husks is higher than the first preset value, and the cotton husk content in the unqualified cotton kernels is higher than the second preset value;

[0014] The separation module is used to separate the unqualified cotton husks and unqualified cotton kernels in the detection module, and perform the detection module again until the cotton kernel content in the unqualified cotton husks is lower than a first preset value, and the cotton husk content in the unqualified cotton kernels is lower than a second preset value.

[0015] In some embodiments of the present application, a cottonseed pretreatment automatic control system further includes:

[0016] The protection module is used to automatically start the protection mode when a device fails during the preprocessing process, that is, to suspend the operation of all devices until all devices are working normally, and then automatically turn off the protection mode.

[0017] In some embodiments of the present application, a control method of a cottonseed pretreatment automatic control system is also included, which is used to control the cottonseed pretreatment automatic control system. The control method of the cottonseed pretreatment automatic control system includes:

[0018] Step 1: acquiring cotton seed data to be processed in real time, automatically measuring the cotton seed data to be processed, and setting the speed of the conveyor according to the measuring data;

[0019] Step 2: Determine the feeding frequency in the sheller according to the speed of the conveyor, and test the shelled cotton seeds to detect the cotton kernel content and cotton husk content;

[0020] Step 3: During the conveying process, the conveyor's running speed is detected in real time. Based on the historical running speed of the conveyor when it fails, it is determined whether the conveyor has a fault. If a fault occurs, the conveyor is immediately paused and the cause of the fault is determined.

[0021] In some embodiments of the present application, the step 1 is specifically:

[0022] Set the measurement data intervals as A1, A2, and A3. Among them, A1 is the first measurement interval, A2 is the second measurement interval, and A3 is the third measurement interval, where A1 < A2 < A3;

[0023] Set the conveyor speeds as B1, B2, and B3. Among them, B1 is the first speed, B2 is the second speed, and B3 is the third speed, where B1 < B2 < B3;

[0024] Obtain the cottonseed data a to be processed in real time and automatically measure the measurement data A. According to the relationship between the measurement data value and the conveyor speed value, set the real-time conveyor speed value. Specifically:

[0025] When a < A1, set the real-time conveyor speed value b as the third speed value B3;

[0026] When A1 < a < A2, set the real-time conveyor speed value b as the second speed value B2;

[0027] When A2 < a < A3, set the real-time conveyor speed value b as the first speed B1.

[0028] In some embodiments of the present application, before step two, it further includes temporarily storing the measured cottonseed to be processed in a buffer hopper, determining the material level value in the buffer hopper according to the relationship between the conveyor speed and the measurement data, and sending different alarm signals when the material level value is not within the preset interval. Specifically:

[0029] Set the material level value as m. The material level value intervals include m1 - m2, m3 - m4, and m5 - m6. Among them, m5 - m6 is the high material level interval, m3 - m4 is the medium material level interval, and m1 - m2 is the low material level interval;

[0030] When m1 < m < m2, the material level value m is in the low material level interval, send a signal of too low material level, and stop running;

[0031] When m3 < m < m4, the material level value m is in the medium material level interval, send a signal of normal material level, and run normally;

[0032] When m5 < m < m6, the material level value m is in the high material level interval, send a signal of too high material level, and stop running.

[0033] In some embodiments of the present application, in step two, determine the feeding frequency in the sheller according to the real-time speed of the conveyor. Specifically:

[0034] Preset the feeding frequencies as C1, C2, and C3. Among them, C1 is the first feeding frequency, C2 is the second feeding frequency, and C3 is the third feeding frequency, and C1 < C2 < C3;

[0035] When the real-time conveyor speed value b is the first speed B1, the feeding frequency c is set to the first feeding frequency C1;

[0036] When the real-time conveyor speed value b is the second speed B2, the feeding frequency c is set to the second feeding frequency C2;

[0037] When the real-time conveyor speed value b is the third speed B3, the feeding frequency c is set to the second feeding frequency C3.

[0038] In this embodiment, the feeding frequency in the shelling machine is determined according to the real-time rotation speed of the conveyor. When the rotation speed of the conveyor is slow, the feeding frequency in the shelling machine is low.

[0039] In some embodiments of the present application, the hulled cotton seeds are tested in step 2 to detect the cotton kernel content and the cotton hull content, specifically:

[0040] Detecting the cotton kernel content and cotton husk content after the initial husk peeling to obtain qualified cotton husks, qualified cotton kernels, unqualified cotton husks, and unqualified cotton kernels, wherein the cotton kernel content in the qualified cotton husks is lower than a first preset value, the cotton husk content in the qualified cotton kernels is lower than a second preset value, the cotton kernel content in the unqualified cotton husks is higher than the first preset value, and the cotton husk content in the unqualified cotton kernels is higher than the second preset value;

[0041] The detected unqualified cotton husks and unqualified cotton kernels are separated again until the cotton kernel content in the unqualified cotton husks is lower than a first preset value, and the cotton husk content in the unqualified cotton kernels is lower than a second preset value.

[0042] In this embodiment, a first preset value is set according to the kernel content in the standard husk after husking and separation, and a second preset value is set according to the husk content in the standard kernel after husking and separation. The cotton kernel content and the cotton husk content after the initial husking are compared with the first preset value and the second preset value. If the cotton kernel content in the cotton husk is lower than the first preset value, it is qualified cotton husk and is transported to the husk warehouse. If the cotton husk content in the cotton kernel is lower than the second preset value, it is qualified cotton kernel and is transported to the next processing equipment.

[0043] In some embodiments of the present application, the step three is specifically:

[0044] According to the operating speed of the historical conveyor failure, the operating speed interval is set to consist of a first speed interval v1-v2, a second speed interval v3-v4, a third speed interval v5-v6 and a fourth speed interval v7-v8;

[0045] When the real-time running speed v of the conveyor is in the first speed interval v1-v2, it is determined that the conveyor has a belt immobility fault;

[0046] When the real-time running speed v of the conveyor is in the second speed interval v3-v4, it is determined that the conveyor has a material blocking fault;

[0047] When the real-time running speed v of the conveyor is in the third speed interval v5-v6, it is determined that the conveyor has a belt deviation fault;

[0048] When the real-time running speed v of the conveyor is in the fourth speed interval v7-v8, it is determined that a stall fault occurs in the conveyor.

The modules of the above implementation scenarios can be combined into one module, or can be further split into multiple sub-modules.

[0071] like Figure 2As shown, in some embodiments of the present application, there is also a control method for the automatic control system of cottonseed pretreatment, which is used to control the automatic control system of cottonseed pretreatment. The control method of the automatic control system of cottonseed pretreatment includes:

[0072] Step 1: Obtain the data of cottonseeds to be processed in real time, automatically measure the data of the cottonseeds to be processed, and set the rotation speed of the conveyor according to the measurement data.

[0073] Step 2: Determine the feeding frequency in the huller according to the rotation speed of the conveyor, detect the shelled cottonseeds, and detect the cotton kernel content and cotton shell content.

[0074] Step 3: During the conveying process, detect the running speed of the conveyor in real time, judge whether the conveyor has a fault according to the running speed at the time of the historical conveyor fault. If a fault occurs, pause immediately and determine the cause of the fault.

[0096] The detected unqualified cotton husks and unqualified cotton kernels are separated again until the cotton kernel content in the unqualified cotton husks is lower than a first preset value, and the cotton husk content in the unqualified cotton kernels is lower than a second preset value.

[0097] In some embodiments of the present application, the step three is specifically:

[0098] According to the operating speed of the historical conveyor failure, the operating speed interval is set to consist of a first speed interval v1-v2, a second speed interval v3-v4, a third speed interval v5-v6 and a fourth speed interval v7-v8;

[0099] When the real-time running speed v of the conveyor is in the first speed interval v1-v2, it is determined that the conveyor has a belt immobility fault;

[0100] When the real-time running speed v of the conveyor is in the second speed interval v3-v4, it is determined that the conveyor has a material blocking fault;

[0101] When the real-time running speed v of the conveyor is in the third speed interval v5-v6, it is determined that the conveyor has a belt deviation fault;

[0102] When the real-time running speed v of the conveyor is in the fourth speed interval v7-v8, it is determined that a stall fault occurs in the conveyor.

[0103] Through the description of the above implementation methods, those skilled in the art can clearly understand that the present invention can be implemented by hardware or by software plus a necessary general hardware platform. Based on this understanding, the technical solution of the present invention can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (which can be a CD-ROM, a USB flash drive, a mobile hard disk, etc.), including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods described in each implementation scenario of the present invention.

[0104] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
