[0003] Therefore, the current traditional organic fertilizer fermentation has the problem of low fermentation efficiency. Its fermentation process often progresses slowly, and it usually takes 15 to 20 days to complete the fermentation, which seriously affects the supply efficiency of organic fertilizer and cannot meet the needs of the rapid development of modern agriculture. In addition, the traditional fermentation method consumes a lot of energy. In the manual operation process, it is difficult to achieve efficient use of energy. For example, when adjusting the fermentation temperature and humidity, the heating or humidification equipment may be overused due to the lack of precise control, resulting in a large amount of energy consumption.

[0038] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0039] Example 1

[0040] As shown in the figure, a programmable control fast and efficient organic fertilizer liquid fermentation preparation system includes a control module, a data acquisition module, a feed processing module, a fermentation tank and a discharge storage module;

[0041] A control module, wherein the control module is respectively connected to the data acquisition module, the feed processing module, the fermentation tank and the discharging storage module, and is used to set a fermentation control method for the organic fertilizer, and controls the fermentation process of the organic fertilizer by controlling the feed processing module and the fermentation tank according to the organic fertilizer liquid fermentation data acquired by the data acquisition module;

[0042] A data acquisition module, which is connected to the fermentation tank and is used to collect fermentation data generated during the organic fertilizer fermentation process and transmit the fermentation data to the control module;

[0043] A feed processing module, the feed module includes a crushing device, a heating device and a ventilation and oxygen supply device, which is used to process the production materials of organic fertilizer; the crushing device, the heating device and the ventilation and oxygen supply device are respectively connected to the fermentation tank; the crushing device is used to crush the raw materials; the heating device is used to adjust the fermentation temperature in the fermentation tank; the ventilation and oxygen supply device is used to input oxygen into the fermentation tank;

[0044] A fermentation tank, the fermentation tank is used to contain and ferment the organic fertilizer liquid;

[0045] A discharging storage module, the discharging module comprises a pipeline pressure pump, a linear vibrating screen and a storage tank; the pipeline pressure pump is respectively connected to the fermentation tank and the linear vibrating screen; the storage tank is connected to the linear vibrating screen; the pipeline pressure pump is used to transport the organic fertilizer liquid in the fermentation tank to the linear vibrating screen; the linear vibrating screen is used to screen the organic fertilizer liquid; the storage tank is used to store the screened organic fertilizer liquid.

[0046] The pulverizing device in the feed processing module is an ultra-fine pulverizer, which pulverizes the raw materials of organic fertilizer to increase the surface area of ​​the raw materials so that they can better contact with microorganisms during the subsequent fermentation process, thereby improving the fermentation efficiency. The heating device is a constant temperature steam generation controller, which adjusts the temperature in the fermentation tank according to the instructions of the control module to create a suitable temperature environment for the growth and reproduction of microorganisms. The ventilation and oxygen supply device is a pneumatic oxygen supply machine, which inputs oxygen into the fermentation tank to meet the oxygen demand of aerobic microorganisms.

[0047] The fermentation tank is the main place for organic fertilizer liquid fermentation. It has a stirring function. Through continuous stirring, the raw materials and microorganisms are fully mixed to ensure uniform fermentation. Under suitable conditions such as temperature and oxygen content, microorganisms decompose the organic matter in the raw materials and convert them into organic fertilizer liquid. Stirring in the fermentation tank can also prevent the raw materials from settling and local overheating, which is conducive to improving the fermentation quality and speed.

[0048] The data acquisition module collects data such as temperature, oxygen content, pH value, etc. during the fermentation process in real time through various sensors installed in the fermentation tank, and transmits these data to the control module. The control module determines whether the fermentation process is normal based on these data. If the data deviates from the target value, the control module will issue corresponding instructions to adjust the working parameters of the feed processing module and the fermentation tank to ensure that the fermentation process is always in the best state.

[0049] After fermentation is completed, the discharge storage module starts working. The pipeline booster pump transports the organic fertilizer liquid in the fermentation tank to the linear vibrating screen, which screens the organic fertilizer liquid to remove impurities and incompletely fermented solid particles. Finally, the storage tank stores the screened organic fertilizer liquid for subsequent irrigation and other uses.

[0050] The control module is a programmable controller. The staff can adjust the fermentation parameters of the organic fertilizer through the control module to achieve rapid fermentation production of organic fertilizers of different specifications and needs.

[0051] Example 2

[0052] The difference between this embodiment and embodiment 1 is that the fermentation control method of organic fertilizer comprises the following steps:

[0053] Acquire temperature data, pH data and oxygen content data collected by the data acquisition module;

[0054] Set the target parameter value of organic fertilizer fermentation and set the fuzzy control rule of organic fertilizer fermentation; calculate the parameter value deviation according to the target parameter value and the collected temperature data, pH data and oxygen content data;

[0055] According to the fuzzy control rules and parameter value deviation of organic fertilizer fermentation, the working parameters of the feed processing module are adjusted. The control module sets the target parameter values ​​of organic fertilizer fermentation, such as setting a specific temperature range, pH range and oxygen content range suitable for microbial growth and fermentation. At the same time, the fuzzy control rules of organic fertilizer fermentation are set, which are used to determine the strategy of adjusting the feed processing module according to the deviation between the actual collected data and the target parameter value.

[0056] The parameter value deviation is calculated based on the target parameter value and the actual temperature data, pH data and oxygen content data collected. This deviation reflects the gap between the current fermentation state and the ideal fermentation state. According to the fuzzy control rules of organic fertilizer fermentation and the calculated parameter value deviation, the control module adjusts the working parameters of the feed processing module. If the temperature is low, adjust the heating device to increase the temperature of the fermentation tank; if the oxygen content is insufficient, adjust the ventilation and oxygen supply device to increase the oxygen supply. By continuously adjusting the working parameters of the feed processing module, the best environmental conditions are created for the organic fertilizer fermentation in the fermentation tank, thereby improving the fermentation efficiency and quality.

[0057] The working principle of this embodiment is the same as that of Embodiment 1.

[0058] Example 3

[0059] The difference between this embodiment and embodiment 2 is that the fuzzy control rule for setting the organic fertilizer fermentation comprises the following steps:

[0060] Set the temperature target parameters and oxygen content target parameters of the organic fertilizer fermentation process;

[0061] The temperature fuzzy set of the organic fertilizer fermentation process is set according to the temperature target parameter, and the oxygen content fuzzy set of the organic fertilizer fermentation process is set according to the oxygen content target parameter;

[0062] Obtain temperature data and oxygen content data during the organic fertilizer fermentation process;

[0063] The temperature of organic fertilizer fermentation is adjusted according to the temperature data and the temperature fuzzy set; the oxygen content of organic fertilizer fermentation is adjusted according to the oxygen content data and the oxygen content fuzzy set.

[0064] The temperature fuzzy set of the organic fertilizer fermentation process is set according to the temperature target parameter, and the temperature is divided into fuzzy concept intervals such as high temperature, medium temperature, and low temperature. Similarly, the oxygen content fuzzy set of the organic fertilizer fermentation process is set according to the oxygen content target parameter, such as high oxygen content, medium oxygen content, and low oxygen content.

[0065] For temperature adjustment, the obtained temperature data is compared with the temperature fuzzy set. If the current temperature is within the high temperature fuzzy set range, it indicates that the temperature is too high. The system can adjust the heating device in the feed processing module through the control module to lower the temperature, or take other cooling measures, such as increasing ventilation, etc. If it is within the low temperature fuzzy set range, the temperature is increased accordingly.

[0066] The oxygen content is adjusted based on the oxygen content data and the oxygen content fuzzy set. If the oxygen content is in the low oxygen content fuzzy set, the control module may need to adjust the ventilation and oxygen supply device to increase the oxygen content input to meet the oxygen demand of the microorganisms during the fermentation process.

[0067] The working principle of this embodiment is the same as that of Embodiment 1.

[0068] Example 4

[0069] The difference between this embodiment and embodiment 3 is that the fuzzy control rule for setting the organic fertilizer fermentation also includes setting the pH value fuzzy control rule during the organic fertilizer fermentation process. By setting the pH value fuzzy control rule during the organic fertilizer fermentation process, the stability of the fermentation environment can be better maintained and the growth and metabolism of microorganisms can be promoted.

[0070] The working principle of this embodiment is the same as that of Embodiment 1.

[0071] Example 5

[0072] The difference between this embodiment and embodiment 4 is that the setting of the pH value fuzzy control rule in the organic fertilizer fermentation process comprises the following steps:

[0073] Set the pH target parameter value of the organic fertilizer fermentation process, and draw the pH target parameter curve according to the pH target parameter value;

[0074] The pH value judgment fuzzy set is set according to the pH value target parameter curve; the pH value of the organic fertilizer fermentation process is obtained, and the pH value actual curve is drawn according to the pH value of the organic fertilizer fermentation process;

[0075] The actual pH value curve and the pH value target parameter curve are judged according to the pH value judgment fuzzy set;

[0076] Obtain the pH value judgment result of the organic fertilizer fermentation process.

[0077] The pH target parameter value of the organic fertilizer fermentation process is set according to the pH range suitable for microbial growth during the organic fertilizer fermentation process. Then, a pH target parameter curve is drawn based on this pH target parameter value, which can intuitively show the ideal pH change trend at different fermentation stages.

[0078] The system continuously obtains the pH value of the organic fertilizer fermentation process through the data acquisition module, and draws the actual pH value curve based on these values. This curve reflects the change of pH value during the actual fermentation process. Then, the actual pH value curve and the pH value target parameter curve are judged according to the pH value judgment fuzzy set. By comparing the fuzzy intervals of the two curves in the same time period, it can be determined whether the pH value in the current fermentation process deviates from the ideal state.

[0079] When the actual pH value curve and the target pH value parameter curve are judged according to the pH value judgment fuzzy set, the instantaneous change rate of the actual pH value curve and the target pH value parameter curve are calculated respectively; the positive and negative values ​​of the instantaneous change rate of the target pH value parameter curve are used as the judgment conditions of the fuzzy set. When the positive and negative values ​​of the instantaneous change rate of the actual pH value curve are different from the positive and negative values ​​of the instantaneous change rate of the target pH value parameter curve in a certain time period, such as the instantaneous change rate of the target pH value parameter curve is positive and the instantaneous change rate of the actual pH value curve is negative, it is judged that the fermentation of the organic fertilizer is not carried out according to the set parameters. The control module can send out an alarm message to notify the staff to check the production process.

[0080] When the actual pH value curve and the target pH value parameter curve are judged according to the pH value judgment fuzzy set, the deviation rate of the actual pH value curve and the target pH value parameter curve is calculated as the judgment condition of the fuzzy set. For example, when the deviation rate is less than 5%, it is judged that the fermentation reaction is proceeding normally, which indicates that the pH value change in the actual fermentation process is very close to the expected target, the system is in a stable state, and the fermentation process is proceeding in an orderly manner according to the established plan; when the deviation rate is greater than 5% and less than 15%, it is judged that there is a deviation in the fermentation reaction. At this time, the fermentation system needs to be closely monitored and the factors that may cause the deviation, such as raw material quality, temperature changes, stirring speed, etc., are analyzed so as to take timely adjustment measures; when the deviation rate is greater than 15%, it is judged that there is a serious problem in the fermentation reaction and the fermentation process should be stopped immediately.

[0081] Wherein, the deviation rate = pH deviation value / pH target value; the pH target value is the value on the pH target parameter curve, and the pH deviation value is the difference between the pH value obtained by actual production measurement and the pH target value at the same time.

[0082] The working principle of this embodiment is the same as that of Embodiment 1.

[0083] Example 6

[0084] This embodiment is different from Embodiment 5 in that the data acquisition module includes a temperature sensor, a pH sensor and an oxygen content sensor, and the temperature sensor, the pH sensor and the oxygen content sensor are installed inside the fermentation tank; the temperature sensor is used to detect the oxygen content of the organic fertilizer in the fermentation tank during the fermentation process; the pH sensor is used to detect the pH value of the organic fertilizer in the fermentation tank during the fermentation process; the oxygen content sensor is used to detect the oxygen content of the organic fertilizer in the fermentation tank during the fermentation process.

[0085] The temperature sensor is a digital temperature sensor with the advantages of small size, high precision, strong anti-interference ability, etc. The temperature sensor transmits data to the control module, and the control module can read the temperature data in real time to monitor and adjust the temperature during the fermentation process. The pH value sensor can use a composite electrode sensor, which can accurately measure the pH value in a complex fermentation environment. The sensor transmits the measured pH value analog signal to the control module through the analog input module.

[0086] The oxygen content sensor adopts a zirconium oxide oxygen sensor, which has the characteristics of fast response speed, high measurement accuracy, good stability, etc. The oxygen content sensor transmits the detected oxygen content data to the control module in the form of an analog signal or a digital signal, so that the control module can monitor and adjust the oxygen content during the fermentation process.

[0087] The working principle of this embodiment is the same as that of Embodiment 1.

[0088] Example 7

The control panel can display more fermentation parameters and status information, such as fermentation progress, raw material consumption, equipment operation status, etc. At the same time, the remote monitoring function can be set to realize remote monitoring and operation of the fermentation system through network connection.

[0091] The control panel can also integrate data analysis and report generation functions, analyze and process the collected fermentation data, generate various reports and charts, and provide a basis for production management and decision-making. In addition, the user authority management function can be set up, and users of different levels have different operating permissions to ensure the safe and stable operation of the system.

[0092] The working principle of this embodiment is the same as that of Embodiment 1.

[0093] Example 8

[0094] This embodiment differs from Embodiment 7 in that it further comprises a fault alarm module; the alarm module is connected to the control module and is used to receive alarm information issued by the control module and issue an alarm.

[0095] The fault alarm module can use an audible and visual alarm mode. When a system fault occurs, an audible and visual signal is emitted to remind the operator to handle it. The fault alarm module can be combined with communication methods such as mobile phone text messages and emails to send fault information to relevant personnel in a timely manner so that timely measures can be taken.

[0096] The fault alarm module can classify and grade different types of faults and take different measures according to the severity of the fault. For example, for a minor fault, an early warning signal can be issued to alert the operator; for a serious fault, the system can be automatically stopped to avoid greater losses.

[0097] The working principle of this embodiment is the same as that of Embodiment 1.

[0098] Example 9

[0099] The difference between this embodiment and embodiment 8 is that the control module is a PLC controller. The control module is a PLC controller, which realizes the control and coordination of the whole system. The PLC controller has the advantages of high stability, high reliability, flexible programming, etc., can meet the control requirements of the organic fertilizer fermentation system, is convenient for integration and expansion with other equipment, and improves the adaptability of the system.
