Description

TECHNICAL FIELD

[0001] The present application relates to the field of animal carcass processing, in particular to a high-temperature animal carcass drying and sterilization device and an intelligent control method thereof. BACKGROUND

[0002] Animal carcasses carry bacteria, viruses and other pathogens, which are transmitted to humans or other animals through air, water sources or direct contact, causing epidemic diseases and environmental pollution. High temperature can destroy the protein structure and nucleic acid chain of pathogens, making them completely inactivated and breaking the transmission chain from the source. Therefore, drying and sterilization of animal carcasses is an important link.

[0003] In related technologies, a conveying device such as a conveyor belt or a spiral conveying shaft with a fixed conveying speed is usually used to convey animal carcass pieces to a high-temperature processing device for drying and sterilization. However, due to the multiple processes in the high-temperature drying and sterilization process of animal carcasses, the fixed conveying speed cannot effectively avoid the accumulation or insufficient phenomenon of animal carcass pieces in the animal carcass breaking process before the conveying process, and cannot guarantee the high-temperature sterilization effect of animal carcass pieces in the high-temperature processing process after the conveying process, thereby resulting in poor regulation effect of the conveying speed of the conveying device in the existing method. SUMMARY

[0004] In order to solve the technical problem of poor regulation effect of the conveying speed of the conveying device in the existing method, the purpose of the present application is to provide a high-temperature animal carcass drying and sterilization device and an intelligent control method thereof, and the technical solution adopted is as follows:

[0005] The present application provides an intelligent control method for a high-temperature animal carcass drying and sterilization device, which comprises:

[0006] Real-time acquisition of the carcass piece accumulation height of the storage bin of the breaking device at each time in the current time period, and the carcass piece temperature and heat source temperature of the high-temperature processing device at each time;

[0007] According to the difference between the carcass piece accumulation height of the storage bin at each time and the adjacent previous time, and the carcass piece accumulation height at each time, the accumulation height state value of the storage bin at each time is obtained.

[0013] Combined with the cadaver block accumulation height change amount and the cadaver block accumulation degree of the storage bin at each time, the accumulation height state value of the storage bin at each time is obtained.

[0014] Further, the obtaining of the accumulation height state value of the storage bin at each time combined with the cadaver block accumulation height change amount and the cadaver block accumulation degree includes:

[0015] Taking any one time in the current time period as a target time, when the cadaver block accumulation height change amount of the storage bin at the target time is greater than 0, the product value of the cadaver block accumulation height change amount and the cadaver block accumulation degree of the storage bin at the target time is taken as the accumulation height state value of the storage bin at the target time;

[0016] When the cadaver block accumulation height change amount of the storage bin at the target time is less than 0, the cadaver block accumulation degree of the storage bin at the target time is negatively correlated and normalized to obtain the cadaver block depletion degree of the storage bin at the target time, and the product value of the cadaver block accumulation height change amount and the cadaver block depletion degree of the storage bin at the target time is taken as the accumulation height state value of the storage bin at the target time;

[0017] When the cadaver block accumulation height change amount of the storage bin at the target time is equal to 0, the accumulation height state value of the storage bin at the target time is set to 0.

[0018] Further, the obtaining of the carcass block accumulation evaluation value of the storage bin comprises:

[0020] Further, the obtaining of the carcass block temperature stability and the heat source temperature stability of the high-temperature processing device comprises:

[0021] The absolute value of the difference between the carcass block temperature of the high-temperature processing device at each time point and the preset standard carcass block temperature is taken as the carcass block temperature deviation value of the high-temperature processing device at each time point.

[0022] The average value of the carcass block temperature deviation value of the high-temperature processing device at all time points is taken as the overall carcass block temperature deviation value of the high-temperature processing device, the dispersion degree of the carcass block temperature deviation value of the high-temperature processing device at all time points is analyzed to obtain the carcass block temperature deviation chaos degree of the high-temperature processing device, and the overall carcass block temperature deviation value and the carcass block temperature deviation chaos degree are comprehensively normalized and negatively correlated to obtain the carcass block temperature stability of the high-temperature processing device.

[0023] The absolute value of the difference between the heat source temperature of the high-temperature processing device at each time point and the preset standard heating temperature is taken as the heating temperature deviation value of the high-temperature processing device at each time point, the calculation method of the carcass block temperature stability of the high-temperature processing device is combined with the heating temperature deviation value of the high-temperature processing device at each time point to obtain the heat source temperature stability of the high-temperature processing device.

[0024] Further, the obtaining of the processing effect evaluation value of the high-temperature processing device comprises:

[0025] In time sequence, a sequence formed by the carcass block temperature of the high-temperature processing device at all time points is taken as the carcass block temperature sequence of the high-temperature processing device, and a sequence formed by the heat source temperature of the high-temperature processing device at all time points is taken as the heat source temperature sequence of the high-temperature processing device.

[0026] The carcass block temperature sequence and the heat source temperature sequence are input into a dynamic time warping algorithm, and the minimum cumulative distance output is negatively correlated to obtain the temperature synchronous change degree of the high-temperature processing device.

[0027] According to the temperature synchronous change degree, the carcass block temperature stability and the heat source temperature stability of the high-temperature processing device, the processing effect evaluation value of the high-temperature processing device is obtained.

[0028] Further, the processing effect evaluation value of the high-temperature processing device is obtained according to the temperature synchronous change degree, the cadaver block temperature stability and the heat source temperature stability of the high-temperature processing device.

[0029] The temperature synchronous change degree, the cadaver block temperature stability and the heat source temperature stability of the high-temperature processing device are comprehensively processed and normalized to obtain the processing effect evaluation value of the high-temperature processing device.

[0030] Further, the adjustment conveying speed of the conveying device in the next time period is obtained by:

[0031] The sum of the cadaver block accumulation evaluation value and the processing effect evaluation value is normalized to obtain the adjustment degree value of the conveying device in the next time period.

[0032] The conveying speed of the conveying device in the next time period is adjusted by using the adjustment degree value of the conveying device in the next time period to obtain the adjustment conveying speed of the conveying device in the next time period.

[0034] The product value of the adjustment degree value of the conveying device in the next time period and the standard conveying speed of the conveying device is taken as the conveying speed adjustment amount of the conveying device in the next time period.

[0035] The sum of the standard conveying speed of the conveying device and the conveying speed adjustment amount of the next time period is taken as the adjustment conveying speed of the conveying device in the next time period.

[0036] The present application also provides a high-temperature animal cadaver drying and sterilization device, which comprises a feeding device, a crushing device, a conveying device and a high-temperature processing device, and further comprises a conveying speed control module, a height sensor for collecting the cadaver block accumulation height of the storage bin of the crushing device, and a temperature sensor for collecting the cadaver block temperature and the heat source temperature of the high-temperature processing device.

[0037] The present application has the following advantages:

[0038] The present application considers that the fixed conveying speed cannot effectively avoid the accumulation or shortage of animal carcass pieces in the animal carcass breaking process before the conveying process, and cannot guarantee the high-temperature sterilization effect of the animal carcass pieces in the high-temperature treatment process after the conveying process, thereby resulting in poor regulation effect of the conveying speed of the conveying device. Therefore, first, the carcass piece accumulation height of the storage bin of the breaking device at each moment in the current time period is obtained in real time, and the carcass piece temperature and heat source temperature of the high-temperature treatment device at each moment are obtained. Considering that the conveying speed of the conveying device is too fast or too slow, the animal carcass pieces in the storage bin will be insufficient or accumulated. Therefore, the present application reflects the trend of the insufficient and accumulation of the animal carcass pieces in the storage bin at each moment through the obtained accumulation height state value, and further reflects the degree of the accumulation or shortage of the animal carcass pieces in the storage bin in the current time period through the carcass piece accumulation evaluation value. Subsequently, the conveying speed can be effectively controlled based on the carcass piece accumulation evaluation value to avoid the accumulation or shortage of the storage bin. Considering that the conveying speed that is too fast or too slow can also affect the treatment effect of the high-temperature treatment device on the animal carcass pieces, and the treatment effect of the animal carcass pieces is related to the stability of the carcass piece temperature, the stability of the heat source temperature, and the synchronization of the changes between the carcass piece temperature and the heat source temperature, the present application further reflects the drying and sterilization treatment effect of the high-temperature treatment device on the animal carcass pieces in the current time period through the obtained treatment effect evaluation value. Then, the conveying speed of the conveying device in the next time period is adjusted in combination with the carcass piece accumulation evaluation value and the treatment effect evaluation value, so as to effectively avoid the accumulation and shortage of the storage bin, and guarantee the drying and sterilization effect of the animal carcass pieces, thereby improving the regulation effect of the conveying speed of the conveying device.

[0040] Figure 1 A high-temperature animal carcass drying and sterilization device intelligent regulation method flow chart is provided for an embodiment of the present application. DETAILED DESCRIPTION

[0041] In order to further illustrate the technical means and effects taken by the present application to achieve the predetermined inventive purpose, the specific implementation, structure, features and effects of the high-temperature animal carcass drying and sterilization device and the intelligent control method thereof according to the present application are described in detail as follows in combination with the drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0043] The specific scheme of the high-temperature animal carcass drying and sterilization device and the intelligent control method thereof according to the present application is specifically described below in combination with the drawings.

[0044] Please refer to Figure 1 which shows the intelligent control method flowchart of the high-temperature animal carcass drying and sterilization device according to one embodiment of the present application, and the method comprises:

[0045] Step S1: Real-time acquisition of the carcass block accumulation height of the storage bin of the crushing device at each time in the current time period, and the carcass block temperature and heat source temperature of the high-temperature treatment device at each time.

[0046] The high-temperature drying and sterilization of animal carcasses generally includes multiple processes, mainly including a feeding process, a crushing process, a conveying process and a high-temperature treatment process. The feeding process mainly feeds the animal carcasses into the crushing device in the crushing process. The crushing device in the crushing process crushes and cuts the animal carcasses into carcass blocks, so that the carcass blocks can be fully heated and sterilized subsequently, and the animal carcass blocks are placed in the storage bin. Then, the conveying process uses conveying devices such as conveyer belts or spiral conveying shafts to convey the animal carcass blocks in the storage bin to the high-temperature treatment device and enter the high-temperature treatment process. In the high-temperature treatment process, the high-temperature treatment device uses heat sources such as heat-conducting oil to dry and sterilize the animal carcass blocks, thereby completing the high-temperature drying and sterilization of the animal carcasses.

[0047] The present embodiment first installs a height sensor in the storage bin of the crushing device. During the process of processing animal carcasses, the height sensor is used to collect the carcass block accumulation height of the storage bin of the crushing device at each time in the current time period in real time. The length of the current time period is usually 10-20 minutes. In one embodiment of the present application, the length of the current time period is set to 15 minutes. The subsequent data analysis process is all analysis in the current time period. The length of the current time period can also be set by the implementer according to the specific implementation scene, which is not limited here.

[0048] The embodiment of the present application also needs to collect the carcass temperature and heat source temperature of the high-temperature treatment device at each moment in the current time period in real time by using a temperature sensor, wherein, in the high-temperature treatment device, heat-conducting oil can be selected as the heating heat source of the animal carcass.

[0049] Step S2: obtaining the accumulation height state value of the storage bin at each moment according to the difference between the carcass accumulation height of the storage bin between each moment and the adjacent previous moment and the carcass accumulation height at each moment; and obtaining the carcass accumulation evaluation value of the storage bin according to the overall level of the accumulation height state values of the storage bin at all moments.

[0050] When the conveying speed of the conveying device is not properly controlled, the animal carcass in the storage bin may be accumulated or insufficient, for example, when the conveying speed of the conveying device is too fast, the animal carcass in the storage bin is conveyed too fast, resulting in insufficient animal carcass in the storage bin, and when the conveying speed of the conveying device is too slow, the animal carcass in the storage bin is accumulated, and the accumulation and insufficiency of the animal carcass will affect the efficiency and effect of the high-temperature drying sterilization, therefore, the embodiment of the present application first analyzes the difference between the carcass accumulation height of the storage bin between each moment and the adjacent previous moment and the carcass accumulation height at each moment, and reflects the trend of the insufficient and accumulated animal carcass in the storage bin at each moment through the obtained accumulation height state value, and subsequently, the degree of the accumulated or insufficient animal carcass in the storage bin in the current time period can be accurately analyzed based on the accumulation height state value.

[0051] Preferably, in one embodiment of the present application, the method for obtaining the accumulation height state value of the storage bin at each moment specifically comprises:

[0052] The difference between the carcass accumulation height of the storage bin between each moment and the adjacent previous moment is obtained to obtain the carcass accumulation height change amount of the storage bin at each moment, the carcass accumulation height change amount at a certain moment is positive and greater, indicating that the carcass accumulation height of the storage bin at the moment has a more obvious rising trend, the carcass accumulation height change amount at a certain moment is negative and smaller, indicating that the carcass accumulation height of the storage bin at the moment has a more obvious downward trend, and the carcass accumulation height change amount at a certain moment is 0, indicating that the carcass accumulation height of the storage bin at the moment is in a balanced state.

[0053] It should be noted that the first moment of the current time period does not have an adjacent previous moment, therefore, the carcass accumulation height change amount of the storage bin at the first moment can be set to 0 for subsequent calculation.

[0054] The carcass accumulation height of the storage bin at each moment is taken as a numerator, the height of the storage bin is taken as a denominator, and the ratio is taken as the carcass accumulation degree of the storage bin at each moment. The greater the carcass accumulation degree at a certain moment, the closer the carcass accumulation height of the storage bin at the moment to the height of the storage bin, and thus the more serious the carcass accumulation phenomenon of the storage bin. Conversely, the smaller the carcass accumulation degree at a certain moment, the more serious the carcass shortage phenomenon of the storage bin.

[0055] Therefore, the accumulation height state value of the storage bin at each moment can be obtained in combination with the carcass accumulation height variation and the carcass accumulation degree of the storage bin at each moment.

[0056] Preferably, in an embodiment of the present application, the method for obtaining the accumulation height state value of the storage bin at each moment further comprises:

[0057] Taking any moment in the current time period as a target moment, when the carcass accumulation height variation of the storage bin at the target moment is greater than 0, the animal carcass height of the storage bin has an upward trend at this time, and the greater the carcass accumulation degree at this time, the more serious the accumulation trend of the animal carcass in the storage bin at this time. Therefore, the product value of the carcass accumulation height variation and the carcass accumulation degree of the storage bin at the target moment can be taken as the accumulation height state value of the storage bin at the target moment.

[0058] When the carcass accumulation height variation of the storage bin at the target moment is less than 0, the animal carcass height of the storage bin has a downward trend at this time, and the smaller the carcass accumulation degree at this time, the more serious the shortage trend of the animal carcass in the storage bin at this time. Therefore, the carcass accumulation degree of the storage bin at the target moment is first subjected to negative correlation normalization processing, and the calculation result is limited to the range of [0, 1], so as to obtain the carcass depletion degree of the storage bin at the target moment, and the product value of the carcass accumulation height variation and the carcass depletion degree of the storage bin at the target moment can be taken as the accumulation height state value of the storage bin at the target moment.

[0059] When the carcass accumulation height variation of the storage bin at the target moment is equal to 0, the animal carcass height in the storage bin is in a balanced state at this time. Therefore, the accumulation height state value of the storage bin at the target moment can be set to 0.

[0060] As an example, in an embodiment of the present application, the expression of the accumulation height state value of the storage bin at the target moment can be specifically, for example:

[0061]

[0062] Wherein, A represents the accumulation height state value of the storage bin at the target time; Dh represents the change of the accumulation height of the carcass block of the storage bin at the target time; h represents the accumulation height of the carcass block of the storage bin at the target time; H represents the height of the storage bin. represents the accumulation degree of the carcass block of the storage bin at the target time. represents the depletion degree of the carcass block of the storage bin at the target time, and is the normalized processing of the negative correlation of the accumulation degree of the carcass block .

[0063] The accumulation height state value of the storage bin at each time can be obtained by the same method, and the overall level of the accumulation height state value of the storage bin at all times in the current time period can be analyzed. The accumulation evaluation value of the carcass block reflects the degree of accumulation or deficiency of the carcass block of the storage bin in the current time period. The conveying speed can be effectively controlled based on the accumulation evaluation value of the carcass block to avoid the accumulation or deficiency of the storage bin.

[0064] Preferably, in an embodiment of the present application, the method for obtaining the carcass block accumulation evaluation value of the storage bin specifically comprises:

[0065] The average value of the accumulation height state value of the storage bin at all times is normalized to limit the calculation result in the range of (-1, 1), so as to obtain the carcass block accumulation evaluation value of the storage bin of the crushing device.

[0066] As an example, in an embodiment of the present application, the expression of the carcass block accumulation evaluation value of the storage bin can be specifically, for example:

[0067]

[0068] Wherein, S represents the carcass block accumulation evaluation value of the storage bin; represents the average value of the accumulation height state value of the storage bin at all times in the current time period; tanh() represents the hyperbolic tangent function, which is used for normalization processing and limits the normalized result in the range of (-1, 1).

[0069] Wherein, when the carcass block accumulation evaluation value S is greater than 0 and larger, it means that the storage bin has a more serious accumulation phenomenon of the carcass block in the current time period; when the carcass block accumulation evaluation value S is less than 0 and smaller, it means that the storage bin has a more serious deficiency phenomenon of the carcass block in the current time period; when the carcass block accumulation evaluation value S is equal to 0, it means that the height of the carcass block of the storage bin in the current time period is in a balanced state.

[0070] Step S3: obtaining a cadaver temperature stability and a heat source temperature stability of the high-temperature treatment device according to a difference between the cadaver temperature at each time and a preset standard cadaver temperature, and a difference between the heat source temperature at each time and a preset standard heating temperature; and obtaining a treatment effect evaluation value of the high-temperature treatment device according to a change difference between the cadaver temperature and the heat source temperature of the high-temperature treatment device in time sequence, and the cadaver temperature stability and the heat source temperature stability.

[0071] Since the conveying speed of the conveying device is too fast or too slow, the treatment effect of the high-temperature treatment device on the animal cadaver is also affected. For example, when the conveying speed is too fast, too many animal cadavers are conveyed into the high-temperature treatment device, which causes the high-temperature treatment device to be unable to sufficiently heat the excessive animal cadavers, thereby reducing the effect of high-temperature drying and sterilization on the animal cadavers. When the conveying speed is too slow, too few animal cadavers are conveyed into the high-temperature treatment device, which causes the treatment efficiency of the high-temperature treatment device on the animal cadavers to be low, thereby resulting in poor treatment effect. The treatment effect of the animal cadavers is related to the stability of the temperature of the animal cadavers and the stability of the temperature of the heat source, that is, when the treatment effect of the high-temperature treatment device is good, the temperature of the animal cadavers to be treated is basically maintained near the corresponding standard temperature, and the temperature of the heat source is also maintained near the corresponding standard temperature. Therefore, in the embodiment of the present application, the cadaver temperature stability and the heat source temperature stability of the high-temperature treatment device are first obtained according to the difference between the cadaver temperature at each time and the preset standard cadaver temperature, and the difference between the heat source temperature at each time and the preset standard heating temperature. The treatment effect of the high-temperature treatment device can be accurately analyzed based on the cadaver temperature stability and the heat source temperature stability. The preset standard cadaver temperature is usually in the range of 100-200 degrees Celsius, and the preset standard heating temperature is usually in the range of 200-300 degrees Celsius. In an embodiment of the present application, the preset standard cadaver temperature is set to 150 degrees Celsius, and the preset standard heating temperature is set to 260 degrees Celsius. The preset standard cadaver temperature and the preset standard heating temperature can also be set by the implementer according to the specific implementation scene, which is not limited herein.

[0072] Preferably, in an embodiment of the present application, the method for obtaining the cadaver temperature stability and the heat source temperature stability of the high-temperature treatment device specifically comprises:

[0073] The absolute value of the difference between the cadaver temperature of the high-temperature treatment device at each time and the preset standard cadaver temperature is taken as the cadaver temperature deviation value of the high-temperature treatment device at each time.

[0074] The average of the carcass temperature deviation values of the high-temperature treatment device at all times is taken as the overall carcass temperature deviation value of the high-temperature treatment device, the dispersion degree of the carcass temperature deviation values of the high-temperature treatment device at all times is analyzed, the carcass temperature deviation confusion degree of the high-temperature treatment device is obtained, the smaller the overall carcass temperature deviation value and the carcass temperature deviation confusion degree of the high-temperature treatment device, the more stable the temperature of the animal carcass in the high-temperature treatment device and the more the temperature is maintained near the preset standard carcass temperature, the overall carcass temperature deviation value and the carcass temperature deviation confusion degree are comprehensively processed and negatively correlated normalization processing is performed, the calculation result is limited in the range of (0, 1), and thus the carcass temperature stability degree of the high-temperature treatment device is obtained.

[0075] In the embodiments of the present application, the standard deviation or variance of the carcass temperature deviation values of the high-temperature treatment device at all times can be taken as the carcass temperature deviation confusion degree of the high-temperature treatment device, the dispersion degree of the carcass temperature deviation values of the high-temperature treatment device at all times is analyzed, and the same method can be used to analyze the dispersion degree of data in subsequent steps.

[0076] In the embodiments of the present application, the sum or product of the overall carcass temperature deviation value and the carcass temperature deviation confusion degree can be used to comprehensively analyze the two, and the same method can be used to comprehensively analyze two or more data in subsequent steps.

[0077] In one embodiment of the present application, a negative exponential function with a natural constant e as the base can be used to perform negative correlation normalization processing.

[0078] As an example, in one embodiment of the present application, the expression of the carcass temperature stability degree of the high-temperature treatment device can be specifically, for example:

[0079] E1=exp(-μ1×σ1)

[0080] Wherein, E1 represents the carcass temperature stability degree of the high-temperature treatment device; μ1 represents the average of the carcass temperature deviation values of the high-temperature treatment device at all times, i.e., the overall carcass temperature deviation value of the high-temperature treatment device; σ1 represents the standard deviation of the carcass temperature deviation values of the high-temperature treatment device at all times, i.e., the carcass temperature deviation confusion degree of the high-temperature treatment device; exp() represents an exponential function with a natural constant e as the base, which is used for negative correlation normalization processing.

[0081] Similarly, the absolute value of the difference between the heat source temperature of the high-temperature treatment device at each moment and the preset standard heating temperature is taken as the heating temperature deviation value of the high-temperature treatment device at each moment, based on the calculation method of the carcass temperature stability of the high-temperature treatment device, and in combination with the heating temperature deviation value of the high-temperature treatment device at each moment, the heat source temperature stability of the high-temperature treatment device is obtained. The greater the heat source temperature stability is, the more stable the temperature of the heating heat source of the high-temperature treatment device is and the temperature is maintained near the preset standard heating temperature.

[0082] As an example, in an embodiment of the present application, the expression of the heat source temperature stability of the high-temperature treatment device can be specifically, for example:

[0083] E2 = exp(-μ2 x σ2)

[0084] Wherein, E2 represents the heat source temperature stability of the high-temperature treatment device; μ2 represents the average value of the heating temperature deviation value of the high-temperature treatment device at all moments; σ2 represents the standard deviation of the heating temperature deviation value of the high-temperature treatment device at all moments; exp() represents the exponential function with the natural constant e as the base, which is used for the normalization processing of negative correlation.

[0085] In the case that the heat source temperature is stable and the animal carcass temperature is stable in the high-temperature treatment device, the more synchronous the changes in time sequence between the heat source temperature and the animal carcass temperature are, the more balanced the temperature of the animal carcass treatment process of the high-temperature treatment device is, and thus the better the effect of the high-temperature treatment device on the animal carcass sterilization treatment is. Therefore, the processing effect evaluation value of the high-temperature treatment device can be obtained according to the difference in time sequence between the carcass temperature and the heat source temperature of the high-temperature treatment device, and the carcass temperature stability and the heat source temperature stability. The greater the processing effect evaluation value is, the better the effect of the high-temperature treatment device on the animal carcass treatment in the current time period is, and subsequently the conveying speed of the conveying device can be effectively regulated in combination with the processing effect evaluation value of the high-temperature treatment device and the carcass accumulation evaluation value of the storage bin.

[0086] Preferably, in an embodiment of the present application, the method for obtaining the processing effect evaluation value of the high-temperature treatment device specifically comprises:

[0087] According to the time sequence, the sequence formed by the carcass temperature of the high-temperature treatment device at all moments is taken as the carcass temperature sequence of the high-temperature treatment device, and the sequence formed by the heat source temperature of the high-temperature treatment device at all moments is taken as the heat source temperature sequence of the high-temperature treatment device.

[0088] The corpse block temperature sequence and the heat source temperature sequence are input into a dynamic time warping algorithm, and a minimum cumulative distance output by the dynamic time warping algorithm is negatively correlated to obtain a temperature synchronous change degree of the high-temperature treatment device. The greater the temperature synchronous change degree is, the more synchronous the temperature of the animal corpse block in the high-temperature treatment device and the heat source temperature are in time sequence.

[0089] Further, the processing effect evaluation value of the high-temperature treatment device can be obtained according to the temperature synchronous change degree, the corpse block temperature stability and the heat source temperature stability.

[0090] Preferably, in an embodiment of the present application, the method for obtaining the processing effect evaluation value of the high-temperature treatment device further comprises:

[0091] The temperature synchronous change degree, the corpse block temperature stability and the heat source temperature stability are comprehensively processed and normalized to limit the calculation result in the range of (0, 1), so as to obtain the processing effect evaluation value of the high-temperature treatment device.

[0092] As an example, in an embodiment of the present application, the expression of the processing effect evaluation value of the high-temperature treatment device can be specifically as follows:

[0093]

[0094] Wherein, P represents the processing effect evaluation value of the high-temperature treatment device; E1 represents the corpse block temperature stability of the high-temperature treatment device; E2 represents the heat source temperature stability of the high-temperature treatment device; DTW represents the minimum cumulative distance between the corpse block temperature sequence and the heat source temperature sequence output by the dynamic time warping algorithm; represents the temperature synchronous change degree of the high-temperature treatment device; tanh() represents a hyperbolic tangent function for normalization processing; ε represents a preset adjustment parameter for preventing the denominator from being 0, and the value range of ε is [0.001, 0.01], in an embodiment of the present application, ε is set to 0.01, and the specific value of ε can also be set by the implementer according to the specific implementation scene, which is not limited herein.

[0095] It should be noted that in other embodiments of the present application, negative correlation mapping can also be realized by other basic mathematical operations, which will not be repeated here.

[0096] Step S4: adjusting the conveying speed of the conveying device in the next time period according to the corpse block accumulation evaluation value and the processing effect evaluation value, to obtain the adjusted conveying speed of the conveying device in the next time period.

[0097] The carcass accumulation evaluation value of the storage bin is greater than 0 and the greater the carcass accumulation evaluation value is, and the greater the processing effect evaluation value is, indicating that the storage bin has a more serious carcass accumulation phenomenon in the current time period, and the processing effect of the high-temperature processing device is better, at this time, the conveying speed of the conveying device in the next time period can be appropriately increased to reduce the carcass accumulation phenomenon in the storage bin and ensure the processing effect of the high-temperature processing device, when the carcass accumulation evaluation value of the storage bin is less than 0 and the smaller the carcass accumulation evaluation value is, and the smaller the processing effect evaluation value is, indicating that the storage bin has a more serious carcass shortage phenomenon in the current time period, and the processing effect of the high-temperature processing device is poorer, at this time, the conveying speed of the conveying device in the next time period can be appropriately reduced to reduce the carcass shortage phenomenon in the storage bin and ensure the processing effect of the high-temperature processing device, therefore, the conveying speed of the conveying device in the next time period can be adjusted by combining the carcass accumulation evaluation value and the processing effect evaluation value, to obtain the adjusted conveying speed of the conveying device in the next time period.

[0098] Preferably, in an embodiment of the present application, the method for obtaining the adjusted conveying speed of the conveying device in the next time period specifically comprises:

[0099] The sum of the carcass accumulation evaluation value and the processing effect evaluation value is normalized to limit the calculation result in the range of (-1, 1), thereby obtaining the adjustment degree value of the conveying device in the next time period, when the adjustment degree value is less than 0, it indicates that the conveying speed needs to be reduced, and when the adjustment degree value is greater than 0, it indicates that the conveying speed needs to be increased.

[0100] Further, the conveying speed of the conveying device in the next time period can be adjusted by using the adjustment degree value of the conveying device in the next time period, to obtain the adjusted conveying speed of the conveying device in the next time period.

[0103] The sum of the standard conveying speed of the conveying device and the conveying speed adjustment amount in the next time period is taken as the adjusted conveying speed of the conveying device in the next time period.

[0104] As an example, in an embodiment of the present application, the expression of the adjusted conveying speed of the conveying device in the next time period can be specifically for example:

[0105] V ′ = V + W x V

[0106] W = tanh(S + P)
