[0002] Currently, cremation machines are commonly used for cremation. However, during operation, the temperature of the entire crematorium furnace needs to be set and maintained at a very high temperature for a long period of time.

[0003] Operating in such a high-temperature environment for a long time will seriously affect the service life of the cremator. Furthermore, the cremation flue gas in the high-temperature environment will carry away a large amount of heat, resulting in energy waste, increased environmental pollution, and other environmental drawbacks.

[0004] Therefore, the industry urgently needs a cremation method to overcome the aforementioned shortcomings of existing cremation methods for cremating remains. Summary of the Invention

[0008] According to the present invention, a staged cremation method based on cremation temperature further includes presetting a first preset cremation temperature, a second preset cremation temperature, and a third preset cremation temperature, specifically: determining that the first preset cremation temperature is within a first preset temperature range of 500±k1℃; determining that the second preset cremation temperature is within a second preset temperature range of 650±k2℃; and determining that the third preset cremation temperature is within a third preset temperature range of 900±k3℃; wherein k1, k2, and k3 are pre-set constants.

[0009] According to the present invention, a staged cremation method based on cremation temperature is provided, wherein k1 is determined based on the coffin, clothing and burial goods associated with the target remains; and k2 is greater than k3.

[0010] According to the present invention, a staged cremation method based on cremation temperature is provided, wherein the cremation flue gas generated in any cremation stage is treated independently.

[0011] According to the present invention, a staged cremation method based on cremation temperature is provided, wherein the furnace unit used to perform the cremation of the target remains in the first cremation stage, the second cremation stage, and the third cremation stage is either the same furnace unit or not the same furnace unit.

[0012] According to a staged cremation method based on cremation temperature provided by the present invention, when it is determined that the furnace units used to perform the cremation of the target remains in the first cremation stage, the second cremation stage, and the third cremation stage are not the same furnace unit, after controlling any target remains to enter the second cremation stage or the third cremation stage, the method further includes: controlling another remains to enter the first cremation stage; sequentially controlling the other remains to pass through the first cremation stage, the second cremation stage, and the third cremation stage to complete the cremation of the other remains; the target remains and the other remains will not be in the same furnace unit at the same time.

[0013] According to the present invention, a staged cremation method based on cremation temperature is provided, wherein cremation images of the target remains are acquired during any cremation stage; the cremation images are input into a state recognition model to obtain an ideal cremation temperature output by the state recognition model; and the preset cremation temperature of any cremation stage is adjusted to the ideal cremation temperature.

[0014] Secondly, the present invention also provides a staged cremation system based on cremation temperature, comprising: a stage setting unit, used to divide the cremation process into at least two consecutive cremation stages according to the difference in the highest cremation temperature when different cremated materials are cremated during the cremation process; a stage control unit, used to control any target remains to sequentially pass through the at least two consecutive cremation stages to complete the cremation of the target remains; and a temperature control unit, used to control the temperature in the furnace unit used to perform the cremation of the target remains in any cremation stage to reach a preset cremation temperature; the preset cremation temperature corresponding to each cremation stage is different.

[0015] Thirdly, the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the staged cremation method based on cremation temperature as described above.

[0016] Fourthly, the present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the staged cremation method based on cremation temperature as described above.

[0029] The following is combined Figures 1 to 5 This invention describes the staged cremation method, system, electronic device, and medium based on cremation temperature provided by the present invention.

[0030] Figure 1 This is a schematic flowchart of the staged cremation method based on cremation temperature provided by the present invention, as shown below. Figure 1 As shown, including but not limited to the following steps:

[0031] Step 101: Based on the differences in the maximum cremation temperature when different materials are cremated during the cremation process, the cremation process is divided into at least two consecutive cremation stages.

[0032] Specifically, during the cremation process, different materials have different ignition points, resulting in varying maximum cremation temperatures. Based on these differences in maximum cremation temperatures, the cremation process can be divided into at least two consecutive stages.

[0033] For example, the skeleton is often the most difficult cremation material to burn during the cremation process, meaning that the maximum cremation temperature of the skeleton is usually the highest. Therefore, based on the difference between the maximum cremation temperature of the skeleton and the maximum cremation temperature of other cremation materials, the cremation process can be divided into two consecutive cremation stages. The first cremation stage mainly involves cremating the materials other than the skeleton, while the second cremation stage mainly involves cremating the skeleton.

[0034] Step 102: Control any target remains to pass through at least two consecutive cremation stages in sequence to complete the cremation of the target remains.

[0035] After dividing the cremation process into at least two consecutive cremation stages, it is possible to further control any target remains to pass through the above at least two consecutive cremation stages in sequence to complete the cremation of the target remains.

[0036] It should be noted that the cremation time for each stage of the cremation process must be greater than or equal to the designated time for each stage to ensure that the remains are fully cremated at each stage. The designated time for each stage can be pre-set according to the specific cremation requirements of the scenario.

[0037] As an optional embodiment, the target remains can sequentially pass through at least two cremation stages in the main furnace of the same furnace unit of the cremator. The operating environment parameters (e.g., cremation temperature) of the main furnace are adjusted to match the operating parameters corresponding to different cremation stages in order to complete the cremation of the target remains.

[0038] As another optional embodiment, the target remains can sequentially pass through at least two cremation stages in the main furnace of multiple furnace units of the cremator. By moving the target remains sequentially into different furnace units, and the operating environment parameters of the main furnace of at least two different furnace units are different, the target remains can sequentially pass through at least two cremation stages to complete the cremation of the target remains.

[0039] Step 103: During any cremation stage, control the temperature within the furnace unit used to perform the cremation of the target remains to reach a preset cremation temperature.

[0040] The preset cremation temperature is different for each cremation stage.

[0041] Specifically, during any cremation stage of the target remains, the temperature within the furnace unit used to perform the cremation is controlled to reach a preset cremation temperature. The preset cremation temperature is different for each cremation stage.

[0042] As an optional embodiment, when the target remains are cremated in the main furnace of the same furnace unit of the cremator through at least two cremation stages, the preset cremation temperature for different cremation stages can be preset. When the target remains begin any cremation stage, the temperature in the main furnace of the furnace unit where the target remains are cremated is controlled to reach the corresponding preset cremation temperature to ensure that the cremation temperature requirement for that cremation stage is met.

[0043] The preset cremation temperature for different cremation stages can be determined based on the highest cremation temperature of the cremated material corresponding to each stage. For example, if a certain cremation stage mainly cremates the skeleton, and the highest cremation temperature of the skeleton is around 900℃, then the preset cremation temperature for that stage can be set to 900℃ based on the highest cremation temperature of the skeleton.

[0044] As another optional embodiment, when the target remains are cremated in the main furnace of multiple furnace units of the cremator through at least two cremation stages in sequence, the preset cremation temperature of the main furnace of different furnace units can be preset.

[0045] For example, when the two cremation stages of a body are completed through the main furnaces of two different furnace units, the preset cremation temperature in the main furnace of the first furnace unit when cremating the body can be set to 500°C, while the preset cremation temperature in the main furnace 2 of the next furnace unit that is connected to the first furnace unit can be set to 900°C. Thus, by controlling the target body to pass through the two furnace units in sequence, the cremation of the target body can be completed.

[0046] Therefore, since the maximum temperature of the first furnace unit is set at only 500℃, compared to a maximum temperature of 900℃, the impact of the maximum temperature on the service life of the first furnace unit will be significantly reduced, thus extending its service life. Furthermore, the temperature of the high-temperature flue gas generated during cremation within the first furnace unit will also be correspondingly lower, effectively reducing the heat carried away by the high-temperature cremation flue gas, reducing the difficulty of subsequent flue gas treatment, saving fuel energy, and achieving more environmentally friendly cremation.

[0047] Optionally, when the preset ignition temperature in the main furnace of a certain furnace unit is set at 900°C and the operating time reaches the rated threshold, the preset ignition temperature in the main furnace of that furnace unit can be reduced, and the preset ignition temperature in the main furnace of another furnace unit can be increased to 900°C. By rotating the preset ignition temperature in the main furnace of different furnace units, the working life of each furnace unit can be better protected.

[0048] The present invention provides a staged cremation method based on cremation temperature. According to the difference in the maximum cremation temperature of different cremated materials during cremation, the cremation temperature of different furnace units is precisely controlled in stages. This avoids the cremator used for cremation from operating at high temperatures for a long time, thus extending the working life of the cremator. It can also effectively reduce the heat carried away by the high-temperature cremation flue gas during cremation, save fuel energy, and achieve more environmentally friendly cremation.

[0049] Based on the above embodiments, as an optional embodiment, controlling any target remains to sequentially undergo at least two consecutive cremation stages includes:

[0050] The remains of the target were cremated in three stages in sequence: the first cremation stage, the second cremation stage, and the third cremation stage.

[0051] Before the target remains enter the first cremation stage, the temperature inside the furnace unit that performs the cremation of the target remains is controlled to reach the first preset cremation temperature.

[0052] Before the target remains enter the second cremation stage, the temperature inside the furnace unit that performs the cremation of the target remains is controlled to reach the second preset cremation temperature.

[0053] Before the target remains enter the third cremation stage, the temperature inside the furnace unit that performs the cremation of the target remains is controlled to reach the third preset cremation temperature.

[0054] The first preset cremation temperature is lower than the second preset cremation temperature, and the second preset cremation temperature is lower than the third preset cremation temperature.

[0055] Specifically, based on the differences in the maximum cremation temperature when different materials are cremated during the cremation process, the cremation process can be divided into a first cremation stage, a second cremation stage, and a third cremation stage. When cremating a target body, it can be controlled to sequentially pass through the first, second, and third cremation stages.

[0056] Furthermore, before the target remains enter the first cremation stage, the temperature inside the furnace unit for cremating the target remains is controlled to reach the first preset cremation temperature corresponding to the first cremation stage; before the target remains enter the second cremation stage, the temperature inside the furnace unit for cremating the target remains is controlled to reach the second preset cremation temperature corresponding to the second cremation stage; before the target remains enter the third cremation stage, the temperature inside the furnace unit for cremating the target remains is controlled to reach the third preset cremation temperature corresponding to the third cremation stage.

[0057] In other words, before the target remains enter any cremation stage, the temperature inside the furnace unit for cremating the target remains needs to be controlled in advance to reach the preset cremation temperature corresponding to any cremation stage, so as to ensure that the temperature inside the furnace unit can meet the cremation requirements of any cremation stage.

[0058] The first preset cremation temperature is lower than the second preset cremation temperature, and the second preset cremation temperature is lower than the third preset cremation temperature.

[0059] Therefore, the target remains can undergo preliminary cremation in the first cremation stage, such as cremating the coffin, clothing, etc. related to the target remains; in the second cremation stage, the target remains can undergo further cremation, such as cremating the flammable organic matter of the target remains; in the third cremation stage, the target remains can undergo complete cremation, such as cremating the skeleton of the target remains.

[0060] As an optional embodiment, the furnace unit used to perform the cremation of the target remains in the first cremation stage, the second cremation stage, and the third cremation stage may be the same furnace unit or may not be the same furnace unit.

[0061] In other words, when cremating the target remains, the first, second, and third cremation stages can be sequentially passed through the same furnace unit of the cremator, or the first, second, and third cremation stages can be sequentially passed through different furnace units of the cremator.

[0062] Optionally, Figure 2 This is a schematic diagram of the cremator provided by the present invention, as shown below. Figure 2As shown, the cremator includes a first furnace unit 4, a second furnace unit 5, and a third furnace unit 6. Adjacent furnace units are connected by an openable furnace door 1. The target remains can first be placed on a trolley 3 and enter the main furnace 2 of the first furnace unit 4. The first cremation stage is completed by starting the first electric heater 7. The cremation images collected by the high-temperature resistant camera devices installed in the windows 28 on the side walls of each furnace unit can also be used to determine whether the target remains have completed the first cremation stage. After the first cremation stage is completed, the trolley 3 containing the remains is moved through the furnace door 1 and enters the second furnace unit 5. The second cremation stage is completed by starting the first burner 8. Then, the remains enter the third furnace unit 6 and the third cremation stage is completed by starting the second burner 9.

[0063] Therefore, by presetting the cremation temperature in the main furnace 2 of the first furnace unit 4 to the first preset cremation temperature, the cremation temperature in the main furnace 2 of the second furnace unit 5 to the second preset cremation temperature, and the cremation temperature in the main furnace 2 of the third furnace unit 6 to the third preset cremation temperature, the cremation of the target remains can be effectively completed.

[0064] The present invention provides a staged cremation method based on cremation temperature, which divides the cremation process into three different cremation stages and sets three different preset cremation temperatures. This effectively extends the working life of the cremator and also effectively reduces the heat carried away by the high-temperature cremation smoke during cremation, thus saving fuel energy.

[0065] Based on the above embodiments, as an optional embodiment, it further includes pre-setting a first preset cremation temperature, a second preset cremation temperature, and a third preset cremation temperature, specifically:

[0066] The first preset cremation temperature is determined to be within the first preset temperature range of 500±k1℃.

[0067] The second preset cremation temperature is determined to be within the second preset temperature range of 650±k2℃.

[0068] The third preset cremation temperature is determined to be within the third preset temperature range of 900±3℃.

[0069] Among them, k1, k2 and k3 are pre-defined constants.

[0070] Specifically, when setting the first, second, and third preset cremation temperatures, it can be determined that the first preset cremation temperature is within the first preset temperature range of 500±k1℃, the second preset cremation temperature is within the second preset temperature range of 650±k2℃, and the third preset cremation temperature is within the third preset temperature range of 900±k3℃. Here, k1, k2, and k3 are preset constants that can be pre-set according to the specific usage requirements of the scenario.

[0071] Optionally, k1 is determined based on the coffin, clothing, and burial goods associated with the target remains. Since the materials used for the coffin, clothing, and burial goods are different, the maximum cremation temperature of the coffin, clothing, and burial goods associated with the target remains will vary. Based on this difference in maximum cremation temperature, k1 can be preset.

[0072] Furthermore, k2 can be determined based on flammable human organic matter (such as sugars and fats) associated with the target remains, while k3 can be determined based on bones associated with the target remains. Since the maximum cremation temperature of bones associated with the target remains is relatively stable, while the maximum cremation temperatures of different types of flammable human organic matter vary considerably, k2 is greater than k3.

[0073] Therefore, as Figure 2 As shown, the first preset cremation temperature in the main furnace 2 of the first furnace unit 4 is set within the first preset temperature range of 500±k1℃. During the first cremation stage of the target remains in the main furnace 2 of the first furnace unit 4, the coffin, clothing, hair, and combustible funerary items (such as paper and cardboard) related to the target remains are mainly burning. The second preset cremation temperature in the main furnace 2 of the second furnace unit 5 is set within the second preset temperature range of 650±k2℃. The flammable parts of the remains and the flammable organic matter of the remains, such as sugars and fats, are mainly burning. The third preset cremation temperature in the main furnace 2 of the third furnace unit 6 is set within the third preset temperature range of 900±k3℃. The non-flammable parts of the remains and the bones are mainly cremated.

[0074] The staged cremation method based on cremation temperature provided by this invention allows for different pre-set cremation temperatures for the three furnace units, enabling different cremation processes for the remains in different furnace units, thus allowing for more precise management of the cremation process.

[0075] Based on the above embodiments, as an optional embodiment, the cremation flue gas generated in any cremation stage is processed independently.

[0076] Specifically, since the cremation of the remains and burial goods is carried out in stages throughout the cremation process, the cremation smoke produced at different stages will be different. Therefore, different smoke treatment processes can be used to deal with the differences in cremation smoke at different stages.

[0077] Optionally, the treatment of cremation flue gas at different cremation stages is independent and does not affect each other, so that corresponding flue gas after-treatment equipment can be set up for the different cremation flue gas generated at different cremation stages.

[0078] Optionally, such as Figure 2 As shown, during the first cremation stage, the main components burning are the coffin, clothing, hair, and combustible burial goods (such as paper and cardboard). Therefore, the cremation flue gas generated during the first cremation stage mainly includes a large amount of fly ash and acidic gases. In addition, the moisture in the body will also evaporate at high temperatures, so the cremation flue gas generated during the first cremation stage also includes water vapor. Therefore, the first exhaust pipe 10 connected to the first furnace unit 4 is equipped with an alkaline spray fly ash remover 13 and a first dehumidifier 14 in sequence. This allows the cremation flue gas generated in the first furnace unit 4 to pass through the alkaline spray fly ash remover 13 and the first dehumidifier 14 when it enters the main exhaust pipe 11 through the first exhaust pipe 10, so as to effectively remove fly ash and reduce moisture content in the cremation flue gas.

[0079] Optionally, such as Figure 2 As shown, each furnace unit can be equipped with a combustion air duct 15. One end of each combustion air duct 15 is connected to the main furnace 2 of the corresponding furnace unit, and the other end can be connected to a blower 16 for injecting air into the furnace unit. This can effectively improve the combustion efficiency in the main furnace 2 of each furnace unit by supplementing oxygen.

[0080] Optionally, such as Figure 2 As shown, a heat exchanger 17 is also installed between the outer walls of the combustion air duct 15 and the flue gas sub-duct of each furnace unit. After the flue gas generated by combustion enters the heat exchanger 17, it will undergo a heat exchange process with the air in the combustion air duct 15, thereby transferring the heat carried by the flue gas to the air in the combustion air duct 15, thereby increasing the heat of the air in the combustion air duct 15. The air in the combustion air duct 15 is then injected into the main furnace 2 of the furnace unit, which is conducive to ensuring the combustion temperature in the main furnace 2, and can also further effectively reduce the heat carried away by the high-temperature flue gas, saving fuel energy.

[0081] Furthermore, since the target remains are mainly burned during the second cremation stage, which involves the combustion of flammable parts of the remains and flammable organic matter such as sugars and fats, the cremation fumes produced during the second cremation stage mainly consist of oily gases and acidic gases.

[0082] Therefore, as Figure 2 As shown, the second exhaust pipe 10 connected to the second furnace unit 5 is equipped with an oil remover 19 and an acid remover 20 in sequence, so that when the combustion flue gas generated in the second furnace unit 5 enters the main exhaust pipe 11 through the second exhaust pipe 18, the oily gas and acidic gas in the combustion flue gas can be effectively removed.

[0083] Optionally, such as Figure 2 As shown, if the acid remover 20 is a wet acid remover (e.g., acid removal by calcium hydroxide), a large amount of water vapor will be generated during the acid removal process. Therefore, a second dehumidifier 21 needs to be installed between the acid remover 20 and the main exhaust pipe 11. This will effectively reduce the moisture content of the combustion flue gas before it enters the main exhaust pipe 11.

[0084] If the acid remover 20 is not a wet acid remover, then there is no need to install a second dehumidifier 21. The combustion flue gas can enter the main exhaust pipe 11 after passing through the acid remover 20.

[0085] Furthermore, since the third cremation stage mainly involves the cremation of the non-flammable parts of the body and the skeleton, the body will be completely cremated in this stage. The ashes from the burned bones are easily dispersed and form high-temperature smoke. Therefore, the cremation smoke generated in the third cremation stage mainly consists of high-temperature smoke.

[0086] Optionally, such as Figure 2 As shown, the third exhaust pipe 22 connected to the third furnace unit 6 is equipped with a high-temperature dust collector 23, so that when the combustion flue gas generated in the third furnace unit 6 enters the main exhaust pipe 11 through the third exhaust pipe 22, a large amount of high-temperature dust in the combustion flue gas can be effectively removed.

[0087] Furthermore, after preliminary filtration of the cremation flue gas generated in the three different cremation stages, all the cremation flue gas can be collected and further filtered using processes for removing common pollutants and dust removal, before being discharged through a chimney.

[0088] Optionally, such as Figure 2 As shown, the cremation fumes with different characteristics generated in the three different cremation stages undergo targeted preliminary filtration treatment and are then drawn into the main exhaust duct 11. At the end of the main exhaust duct 11, an activated carbon adsorption filter 24, a bag filter 25, and a chimney 26 are sequentially installed. Therefore, the pre-filtered cremation fumes in the main exhaust duct 11 undergo common fumes treatment after passing through the activated carbon adsorption filter 24 and the bag filter 25 to ensure that the overall quality of the generated cremation fumes meets the standards, before being discharged through the chimney 26.

[0089] Optionally, such as Figure 2As shown, an ejector fan 12 is also installed in the bag filter 25 and the chimney 26 of the main exhaust duct 11. When the ejector fan 12 is started, a negative pressure space will be formed in the main furnace 2 of each furnace unit, so that the combustion flue gas generated in each combustion stage can be continuously drawn into the corresponding exhaust sub-duct, and treated by the corresponding flue gas post-treatment equipment, before entering the main exhaust duct, and finally discharged in the chimney 26 after completing the common treatment.

[0090] Furthermore, to ensure complete combustion of the cremation flue gas in the recombustion chamber—that is, to ensure that the reheating time of the cremation flue gas in the recombustion chamber exceeds the rated time—the flue through which the flue gas flows from the recombustion chamber to the exhaust flue can be designed with a curved structure. The reheating time of the flue gas in the recombustion chamber can then be controlled by adjusting the complexity of the curvature. The rated time can be preset according to the specific usage requirements of the scenario, for example, it can be set to 2 seconds.

[0091] Optionally, Figure 3 yes Figure 2 A cross-sectional view of the cremator at point AA, as shown below. Figure 3 As shown, a re-combustion chamber 27 is provided above the main furnace 2 of any furnace unit. The re-combustion chamber 27 is connected to the main furnace 2 so that the combustion flue gas in the main furnace 2 is reheated in the re-combustion chamber 27 and then discharged to the flue gas sub-pipe connected to the re-combustion chamber 27.

[0092] A heating device is installed in the re-combustion chamber 27. The heating device can be a third electric heater or a fourth burner. The combustion flue gas can be reheated by controlling the start of the heating device in the re-combustion chamber 27.

[0093] Optionally, the reheating time of the cremation flue gas in the recombustion chamber 27 can be controlled by adjusting the power of the ejector fan 12.

[0094] Therefore, since the treatment of cremation flue gas at different stages is independent, corresponding flue gas after-treatment equipment can be selected based on the characteristics of the flue gas at each stage, eliminating the need for other unnecessary after-treatment equipment. For example, if the cremation flue gas generated at a certain cremation stage contains acidic gases and water vapor, then the corresponding flue gas treatment system can be equipped with a corresponding acid remover and dehumidifier, eliminating the need for other flue gas after-treatment equipment and improving flue gas treatment efficiency.

[0095] In existing technologies, when all flue gas aftertreatment equipment is connected in series for unified flue gas aftertreatment, the fly ash generated in the first stage becomes the main reaction surface for dioxin formation. It not only easily acts as a carrier, promoting the formation of dioxins and other pollutants from fatty organic matter in subsequent stages, but also tends to deposit on the flue and aftertreatment equipment pipes. This affects the flow of the flue, and the residual carbon, metals, metal oxides, or metal chlorides in the deposited fly ash can come into contact with subsequent flue gas, promoting the formation of dioxin-like pollutants. This application addresses this by pre-treating the fly ash generated in the first stage, effectively avoiding or mitigating these problems. Furthermore, by specifically treating the oily and acidic substances generated in the second stage, the difficulty of treating subsequent cremation flue gas can be effectively reduced, thereby significantly improving the efficiency of flue gas aftertreatment.

[0096] The staged cremation method based on cremation temperature provided by this invention treats the cremation flue gas generated at different cremation stages in a targeted manner, and then performs a common treatment. This not only effectively overcomes the defects of using all flue gas after-treatment equipment in series in the prior art, but also effectively reduces the difficulty of treating cremation flue gas, thereby greatly improving flue gas treatment efficiency and avoiding the waste of the treatment capacity of flue gas after-treatment equipment.

[0097] Based on the above embodiments, as an optional embodiment, if it is determined that the furnace units used to perform the cremation of the target remains in the first cremation stage, the second cremation stage, and the third cremation stage are not the same furnace unit, after controlling any target remains to enter the second or third cremation stage, the method further includes:

[0098] Control another body to enter the first cremation stage.

[0099] The cremation of another body is completed by sequentially controlling the first, second, and third cremation stages.

[0100] Any target remains will not be in the same furnace unit as another remains at the same time.

[0101] Specifically, when it is determined that the furnace units used to perform the cremation of the target remains are not the same furnace unit in the first cremation stage, the second cremation stage, and the third cremation stage, and after controlling any target remains to enter the second cremation stage or the third cremation stage, another remains can be controlled to enter the first cremation stage, and the other remains can be controlled to pass through the first cremation stage, the second cremation stage, and the third cremation stage in sequence to complete the cremation of the other remains.

[0102] It should be noted that the cremation of any one target body and the other body will not be in the same cremation stage at the same time; that is, the cremation process of all bodies is independent and does not interfere with each other.

[0103] As an optional embodiment, such as Figure 2 As shown, after the control vehicle 3 enters the second furnace unit 5, that is, after controlling any target remains to enter the second cremation stage, the control vehicle 3 containing another remains enters the first furnace unit 4, that is, the control vehicle 3 to enter the first cremation stage.

[0104] Furthermore, after any target remains complete the second cremation stage and leave the second furnace unit 5, and the other remains complete the first cremation stage and enter the second furnace unit 5, that is, after entering the second cremation stage, another vehicle containing yet another remains can be controlled to enter the first furnace unit 4, that is, to control yet another remains to enter the first cremation stage.

[0105] In other words, up to three bodies can undergo different cremation stages in three different furnace units at the same time.

[0106] As another alternative embodiment, such as Figure 2 As shown, after the control vehicle 3 enters the third furnace unit 6, that is, after controlling any target remains to enter the third cremation stage, the control vehicle 3 containing another remains enters the first furnace unit 4, that is, the control vehicle 3 to enter the first cremation stage.

[0107] Furthermore, when the other body has completed the first and second cremation stages and entered the third cremation stage, another vehicle containing yet another body can be controlled to enter the first furnace unit 4, that is, to control yet another body to enter the first cremation stage.

[0108] In other words, a maximum of two bodies can undergo different cremation stages in three different furnace units at the same time.

[0109] Optionally, such as Figure 2 As shown, it also includes a closed trolley running track 29 for the trolley 3 to travel on, and at least one section of the trolley running track 29 runs through each furnace unit. That is to say, when the trolley 3 leaves the last furnace unit and the ashes on the trolley 3 have been collected and processed, the trolley 3 can return to the first furnace unit of the cremator along the closed track, so as to wait for the next cremation operation, and finally realize the continuous cycle of cremation process.

[0110] The staged cremation method based on cremation temperature provided by this invention can control another body to enter the first cremation stage after any target body has entered the second or third cremation stage, thereby realizing a continuous cycle of body cremation process and improving body cremation efficiency.

[0111] Based on the above embodiments, as an optional embodiment, it further includes:

[0112] Capture cremation images of the target remains during any cremation stage.

[0113] The cremation image is input into the state recognition model to obtain the ideal cremation temperature output by the state recognition model.

[0114] Adjust the preset cremation temperature of any cremation stage to the ideal cremation temperature.

[0115] Specifically, cremation images of the target remains can be collected by a high-temperature resistant camera device installed in the window 28 on the side wall of each furnace unit. The cremation images are then input into a state recognition model to obtain the ideal cremation temperature output by the state recognition model. Based on the ideal cremation temperature, the preset cremation temperature of the cremation stage corresponding to the cremation image is adjusted.

[0116] The state recognition model is obtained by training historical cremation image samples and the ideal cremation temperature labels corresponding to the historical cremation image samples.

[0117] For example, a historical cremation image sample and the corresponding ideal cremation temperature label can be used as a training sample. Multiple training samples can be obtained as a training dataset, which can then be input into the state recognition model. The model parameters in the state recognition model can be adjusted based on each output result of the state recognition model, thus completing the pre-training process of the state recognition model.

[0118] This can be interpreted as either completing the pre-training process of the state recognition model after reaching a predetermined number of pre-training iterations, or as completing the pre-training process of the state recognition model when the training output of the state recognition model converges.

[0119] The differences between remains of different ages and genders, as well as the different types of burial goods, will lead to significant variations in cremation images during the cremation process. Therefore, by acquiring diverse cremation images as sample data—that is, obtaining multiple cremation images of different ages, genders, and types of burial goods at different cremation stages as sample data—and manually labeling them with the corresponding ideal cremation temperature as sample data labels to form training samples, the state recognition model can be pre-trained. This can effectively improve the recognition ability of the state recognition model, enabling it to more accurately identify the ideal cremation temperature corresponding to cremation images of remains of different ages and genders, as well as different types of burial goods.

[0120] Furthermore, by obtaining the ideal cremation temperature result output by the state recognition model, the preset cremation temperature in any cremation stage is adjusted to the ideal cremation temperature to ensure that the target remains can be effectively cremated in any cremation stage.

[0121] The present invention provides a staged cremation method based on cremation temperature, which obtains the ideal cremation temperature by inputting the cremation image into the state recognition model, and then adjusts the preset cremation temperature of any cremation stage based on the ideal cremation temperature, so as to achieve more precise and refined management of the cremation process of remains at each stage and improve the cremation efficiency.

[0122] Figure 4 This is a schematic diagram of the structure of the staged cremation system based on cremation temperature provided by the present invention, as shown below. Figure 4 As shown, it includes a stage setting unit 41, a stage control unit 42, and a temperature control unit 43, wherein:

[0123] The stage setting unit 41 is used to divide the cremation process into at least two consecutive cremation stages based on the difference in the highest cremation temperature when different cremated materials are cremated during the cremation process.

[0124] The stage control unit 42 is used to control any target remains to pass through the at least two consecutive cremation stages in sequence to complete the cremation of the target remains.

[0125] Temperature control unit 43 is used to control the temperature within the furnace unit used to perform the cremation of the target remains during any cremation stage, so as to reach a preset cremation temperature.

[0126] The preset cremation temperature is different for each cremation stage.

[0128] The present invention provides a staged cremation system based on cremation temperature. According to the difference in the maximum cremation temperature of different cremated materials during cremation, the system adopts precise segmented control of the cremation temperature of different furnace units. This avoids the cremator used for cremation from operating at high temperatures for a long time, thus extending the working life of the cremator. It can also effectively reduce the heat carried away by the high-temperature cremation flue gas during cremation, save fuel energy, and achieve more environmentally friendly cremation.
