[0001] This application relates to the field of toilet technology, and in particular to a control method, device, electronic equipment, and computer storage medium for an eco-toilet. Background Technology

[0002] Common outdoor toilets typically resolve waste disposal issues by flushing. However, in cold, arid, and water-scarce regions, the application of common outdoor toilets is severely limited. To address these limitations, an ecological toilet is proposed.

[0003] Ecological toilets are a form of outdoor toilet. In order to treat the excrement inside the toilet in a harmless manner, microbial decomposition technology can be used to decompose the excrement inside the toilet, or the excrement can be divided into portions and then transported and processed centrally by hand.

[0004] The method of centralized processing by manual handling consumes a lot of human and economic resources. In areas with extreme weather conditions, the use of microbial decomposition technology to decompose and process excrement inside toilets is inefficient. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a control method, device, electronic equipment, and computer storage medium for an ecological toilet, which ensures the normal decomposition of excrement inside the toilet by microorganisms, improves the cleanliness of the environment around the toilet in extreme environments, and saves human and economic resources.

[0006] This application is achieved through the following technical solution.

[0008] Before determining the heat dissipation power consumed by the excrement based on the density of the excrement and the physical properties of the eco-toilet, the method further includes: obtaining the temperature inside the eco-toilet; and when it is determined that the temperature inside the eco-toilet is lower than a first threshold; determining the heat dissipation power consumed by the excrement based on the density of the excrement and the physical properties of the eco-toilet includes: determining the heat dissipation power consumed by the excrement based on the temperature inside the eco-toilet, the density of the excrement, and the physical properties of the eco-toilet.

[0009] After decomposing the excrement, the method further includes: when it is determined that the temperature inside the eco-toilet is lower than a first threshold and / or the brightness outside the eco-toilet is lower than a first set value, maintaining the temperature of the collection and treatment device in the eco-toilet at a set temperature value.

[0010] The physical properties of the eco-toilet include at least one of the following: the size of the eco-toilet; the height of the collection and treatment device in the eco-toilet from the ground; the size of the collection and treatment device in the eco-toilet; the material of the collection and treatment device in the eco-toilet; and the shape of the collection and treatment device in the eco-toilet.

[0011] It also includes: when it is determined that the temperature inside the eco-toilet is lower than a second threshold, and when it is determined that the activity status of one or more objects in the eco-toilet has changed, determining the new activity status of the objects and the new area to which the objects belong; determining the temperature requirement of the new area according to a pre-set correspondence between activity status and temperature requirement; and determining the heat dissipation power of the new area according to the temperature requirement.

[0012] The activity state includes leaving; the new area includes outside the eco-toilet; the temperature requirement of the new area is determined according to a pre-set correspondence between activity state and temperature requirement, including: when it is determined that the activity state is leaving the eco-toilet and the time spent outside the eco-toilet exceeds a set time, the temperature requirement of the eco-toilet is determined to be lowered according to the pre-set correspondence between activity state and temperature requirement; and the activity state includes squatting; the new area includes within the set range of the collection and processing device; the temperature requirement of the new area is determined according to a pre-set correspondence between activity state and temperature requirement, including: when it is determined that the activity state is squatting and within the set range of the collection and processing device, the temperature requirement of the eco-toilet is determined to be raised according to the pre-set correspondence between activity state and temperature requirement.

[0013] Determining the heat dissipation power of the new area based on the temperature requirements includes: determining the amount of heat required to maintain the temperature of the new area based on the temperature requirements; converting the amount of heat into heat dissipation power, and using the converted heat as the heat dissipation power of the new area.

[0016] The ecological toilet control method proposed in this application determines the heat loss power when it is determined that there is excrement and that the excrement is feces or a mixture. The net output power of heat radiation is determined by subtracting the heat loss power from the heat radiation power of the ecological toilet. Based on the density of the excrement and the net output power of heat radiation, the heat dissipation power consumed by the excrement is determined. This method is used to ensure the normal decomposition of excrement inside the toilet by microorganisms, improve the environmental cleanliness around the toilet in extreme environments, and save human and economic resources.

[0027] The following is a detailed description of this application.

[0028] Toilets are one of the baseline measures of social civilization. They are not only related to public health, social equity, and the well-being of vulnerable groups, but also a crucial link between people and the natural environment. Improperly treated excrement not only pollutes land and water resources but also increases the risk of disease transmission. Therefore, toilet reform is urgently needed.

[0029] In related technologies, microbial decomposition technology can be used to decompose and process excrement inside toilets in a harmless manner.

[0030] However, in cold northern regions, outdoor temperatures are low, and outdoor toilets, especially dry toilets, are prone to freezing, which affects the decomposition of excrement by microorganisms. In arid regions lacking water sources, even though temperatures are higher, the lack of water makes exposed excrement a breeding ground for mosquitoes, eventually rendering toilets unusable and further impacting the ecological environment.

[0031] Although some existing toilet renovation projects have involved burying excrement storage tanks below the frost line to prevent freezing, this method involves a large amount of excavation and construction, and the walls of the excrement storage tanks also need to be thickened, which leads to high costs for toilet renovation. Furthermore, because the excrement storage tanks are located deep in the soil, the pressure is greater, which increases the risk of soil pollution and groundwater pollution.

[0032] Based on this, such as Figure 1As shown, this application provides an ecological toilet 01, including a toilet stall 1, a collection and treatment device 2, a heat-conducting channel a, a heat collection plate 3, and a first fan 4. The toilet stall 1 has a toilet opening. The collection and treatment device 2 has a receiving space b communicating with the toilet opening, the receiving space b being used to collect excrement discharged from the toilet opening and to perform microbial treatment. The receiving space b may include a first storage cavity b1 and a second storage cavity b2. In some examples, such as Figure 1 As shown, a toilet stall 1 has an opening communicating with the interior of the toilet stall 1, and a door 11 is connected to the opening. The door 11 is used to open or close the opening to meet the user's toilet needs. The door 11 can be made of any material, such as metal, plastic, stone, wood, or rattan, and no specific limitation is made in this application.

[0033] In some examples, such as Figure 1 The bottom of toilet 1 is also connected to a support platform 12, which plays a supporting role.

[0034] The supporting platform 12 can be made of materials such as cement board or plastic board, and this application does not impose specific limitations. Specifically, the supporting platform 12 can also be stepped.

[0035] In some examples, the heat conduction channel a can be part of the collection and processing device 2. Alternatively, the heat conduction channel a can be a separate pipe that contacts the collection and processing device 2. The key is that the heat in the hot air within the heat conduction channel a can be conducted to the collection and processing device 2, and then to the excrement within the containment space b.

[0036] In some examples, such as Figure 1 As shown, the eco-toilet 01 also includes a toilet seat 13 or a squat toilet installed inside the toilet stall 1, such as a toilet opening formed on the toilet seat 13 or squat toilet. The installation of the toilet seat 13 or squat toilet can improve the toilet experience.

[0037] In some examples, the first fan 4 can be located at the inlet end of the airflow channel c, which can better draw air from outside the toilet 1 into the airflow channel c. Of course, the first fan 4 can also be located in the middle of the airflow channel c.

[0038] Among them, the first fan 4 can be an axial flow fan.

[0039] The processor can be configured in at least one of the following ways: Fully buried underground; partially buried underground; installed above ground; When the collection processor is partially buried and / or above ground, the eco-toilet also includes a sealing plate for enclosing the collection processor; and / or the eco-toilet also includes steps for reducing the height required to reach the collection processor.

[0040] With the above setup, a person can defecate in toilet 1 and discharge the excrement into the receiving space b through the toilet opening. Since the heat collection plate 3 is located outside toilet 1, it can collect solar heat and transfer it to the air in the airflow channel c formed between the heat collection plate 3 and the outer wall of toilet 1. Because the inlet end of the airflow channel c is connected to the outside of toilet 1, and the outlet end of the airflow channel c is connected to the inlet end of the heat conduction channel a, and the outlet end of the heat conduction channel a is connected to the outside of toilet 1, the air that has absorbed heat can flow in the airflow path formed by the airflow channel c and the heat conduction channel a under the action of the first fan 4. When the hot air passes through the heat conduction channel a, the heat in the hot air will be transferred to the receiving space b through the side wall of the heat conduction channel a and the side wall of the collection and treatment device 2, thereby heating the excrement in the receiving space b to ensure that the microorganisms in the receiving space b are in a suitable temperature environment for normal decomposition of the excrement.

[0041] This heating method utilizes solar energy, a clean energy source, eliminating the need for electricity. This reduces energy consumption and operating costs, and is also cleaner and more environmentally friendly. Furthermore, solar energy can maintain the ambient temperature inside the eco-toilet even in extremely cold conditions. If connected to electricity, the electrical energy can be converted into heat energy, or the eco-toilet can be directly controlled by electricity.

[0042] The air inside toilet 1 is generally worse than the air outside toilet 1, so toilet 1 needs to be ventilated to ensure that the air inside toilet 1 is fresh.

[0043] When no one is inside toilet 1, the hot air in the heat conduction channel a will completely enter the exhaust channel d through the outlet of the reversing valve to continuously heat the containment space b.

[0044] like Figure 1 As shown, toilet 1 also has a cleaning passage i that connects to the containment space b. By setting up the cleaning passage i, cleaning personnel can clean the excrement in the containment space b through the cleaning passage i.

[0045] In the case where the containment space b includes a first storage cavity b1 and a second storage cavity b2, the scouring channel i is connected to the first storage cavity b1.

[0046] In some embodiments, the heat-conducting channel may contain a heat-conducting medium. The heat-conducting medium may completely or partially fill the heat-conducting channel, providing heat to the eco-toilet. Because the heat-conducting medium has better heat transfer efficiency than air, it can significantly improve the heat transfer effect. The heat-conducting medium may be hot oil or a two-phase medium.

[0047] Specifically, the two-phase medium can be low-viscosity silicone oil or ethylene glycol-water mixture (antifreeze type), which can be circulated with a magnetic pump to better avoid low-temperature solidification.

[0048] In some embodiments, an integrated plate heat exchanger may also be included to improve the heat exchange efficiency between the two-phase medium and the reaction zone. Heat pipes are embedded in key areas to utilize phase change for rapid heat homogenization.

[0049] The phase change thermal energy storage base (PCM) can be made of paraffin-based materials (phase change temperature 0-5℃) or salt hydrate materials and encapsulated in an aluminum honeycomb structure base.

[0050] In some embodiments, layered thermal storage can also be designed: the upper layer rapidly absorbs heat during the day, while the lower layer slowly releases heat at night, extending the insulation time. A graphene coating is combined to enhance thermal conductivity and improve the heat storage / release rate.

[0051] In some embodiments, intelligent temperature control and system integration can be achieved by incorporating heat conduction channels. For example, adaptive control algorithms can be introduced to dynamically adjust the power of the heating tape based on a PID controller, and preheating can be performed in conjunction with weather forecasts. IoT remote monitoring can also be introduced: temperature and power data can be transmitted in real time via 5G / 4G / LoRa modules, supporting remote intervention.

[0052] In some embodiments, for waste heat recovery from exhaust gas: a heat exchanger can be installed in the exhaust pipe to preheat the cold air entering the system. The reaction chamber adopts a double-layer stainless steel vacuum structure to reduce heat loss.

[0053] Additionally, a cover plate can be installed at the cleaning channel i to close or open the cleaning channel i. The cleaning channel i can be opened when cleaning is needed and closed when cleaning is not needed.

[0054] like Figure 2 As shown, this application provides a method for controlling an ecological toilet, and the specific processing flow is as follows: Step 21: Determine if there is excrement in the collection and processing device. If the result is yes, proceed to step 22. If the result is no, end the processing.

[0055] In the technical solution proposed in this application, different sensors can be installed in the ecological toilet, such as temperature sensors, humidity sensors, infrared sensors, human body sensors, smoke sensors, etc. These sensors can be set in different quantities and different types according to the environment in which the ecological toilet is placed and the data collection needs. In terms of power supply, there are two types: active and passive. Passive can be powered by solar energy, while active can be powered by electricity.

[0056] In practical implementation, the solar collectors in the ecological toilets proposed in this application can generate electricity through photovoltaic power generation, be connected to windmills, collect solar energy, and convert the collected energy into electricity. This allows the ecological toilets proposed in this application to be installed even in arid environments without electricity.

[0057] The solar collector panel in this application can also be connected to a power source, thus adapting to situations where power can be supplied even in harsh environments. For example, in rural areas of the far north, where electricity is available, the solar collector panel can provide power to the eco-toilets.

[0058] In some embodiments, electric heating can be used in low-temperature areas with a minimum temperature of -10 to 0°C. The heat collection plate 3 is used to collect solar energy, which powers the battery. When heating is required, electrical energy is extracted to heat the heating wire, thereby ensuring that the internal temperature reaches the reaction requirements.

[0059] In some embodiments, the solar collector plate may have a reserved electrical interface, which can supply power to the system when environmental conditions permit.

[0060] In some embodiments, designs can also be made for adaptability to extreme environments, such as antifreeze and self-maintenance mechanisms, such as using pipeline electric heating tape + intelligent temperature control, which automatically activates the antifreeze mode when the temperature drops below 2°C.

[0061] In some embodiments, the collector plate may be equipped with a self-cleaning function, such as an integrated vibration motor or a hydrophobic coating, to prevent snow / ice accumulation.

[0062] In some embodiments, critical components (such as pumps and controllers) are equipped with dual-machine hot standby, automatically switching in case of failure, and quick-release pipe interfaces for easy and rapid replacement of damaged modules.

[0063] In some embodiments, the heating device can be adapted to scenarios such as greenhouse soil heating and oil pipeline heat tracing, and the temperature threshold can be adjusted. It can also be expanded into a regional microgrid node to supply power to other devices.

[0064] In some embodiments, vehicle-mounted devices can also be developed for temporary heating in polar scientific expeditions or disaster relief, thus the use of the ecological toilet proposed in this application can better protect the ecological environment.

[0065] In some embodiments, the ecological toilet system proposed in this application features an emergency shutdown triggered by the pressure / leakage sensor of the media circulation system under emergency conditions. The electric heating system includes overcurrent protection and grounding fault detection, meeting IP67 protection standards. Aerospace-grade sealing materials are used, withstanding temperature differences of -40 to 120°C. A self-diagnostic system periodically checks component lifespan and provides early warnings for replacement.

[0066] With the continuous development of technology, machine learning can be used to predict energy consumption curves and dynamically adjust energy storage / consumption strategies. Adding carbon nanotubes / alumina nanoparticles to the heat transfer medium can increase thermal conductivity by more than 20%. Exploring laser charging or microwave power supply can achieve contactless emergency energy replenishment.

[0067] Using the above solution, the eco-toilet can stably maintain a reaction temperature of 5~25℃ in extreme environments down to -30℃, improving overall energy efficiency by more than 40%, while also possessing adaptability to multiple scenarios and high reliability. The next step is recommended to verify the design through digital twin simulation and conduct small-scale field tests to optimize parameters.

[0068] In practice, this application does not impose specific limitations, as long as it can provide the energy required for the corresponding ecological toilet. This energy may include, but is not limited to, kinetic energy, electrical energy, and thermal energy.

[0069] Step 22: If excrement is found, determine the density of the excrement.

[0070] In practical implementation, the ecological toilet proposed in this application has a collection and treatment device that can directly receive excrement. Microorganisms are placed in the collection and treatment device, which can also be connected to a containment space where excrement can be directly discharged. Microorganisms can be placed in the containment space to make the excrement more concentrated. However, this application does not specifically limit the method of receiving excrement.

[0071] The microorganisms can be added individually or all at once; this application does not impose specific restrictions. The microorganisms only need to be able to decompose excrement; the specific components they contain are also not specifically limited in this application.

[0072] When excrement is detected in the collection and processing device and / or containment space, the density of the excrement is determined. Based on the corresponding density, it can be determined whether the excrement is urine, feces, or a mixture.

[0073] Step 23: Determine the heat dissipation power of the waste based on the density of the excrement and the physical properties of the ecological toilet.

[0074] Based on the physical properties of the ecological toilet, the heat loss power is determined. The difference between the heat radiation power and the heat loss power of the ecological toilet is calculated to determine the net output power of heat radiation. Based on the density of the excrement and the net output power of heat radiation, the heat dissipation power of the excrement is determined.

[0075] Different types of excrement require different treatment methods, each with varying heat dissipation capabilities. If the excrement is solely urine, it can be directly heated to evaporate and be discharged. If it's a mixture, the liquid can be evaporated, and the remainder can be used to introduce microorganisms. If the excrement is simply feces, it can be directly heated to the temperature at which microorganisms function.

[0076] In specific implementation, before determining the heat dissipation power of consuming excrement based on the density of excrement and the physical properties of the ecological toilet, the method further includes: obtaining the temperature inside the ecological toilet; and when it is determined that the temperature inside the ecological toilet is lower than a first threshold, determining the heat dissipation power of consuming excrement based on the temperature inside the ecological toilet, the density of excrement, and the physical properties of the ecological toilet.

[0077] In this implementation, when determining the heat dissipation power, the ambient temperature is also taken into account. If the ambient temperature is high, the heat dissipation power can be appropriately reduced to save energy. If the ambient temperature is low, the heat dissipation power can be appropriately increased to provide more heat than that used to decompose the excrement, thereby improving the decomposition effect of the excrement.

[0078] To illustrate, when determining the heat dissipation power required for excrement, if the eco-toilet is in an extremely cold environment, the temperature inside will inevitably be below zero. Excluding the effect of wind on perceived temperature, the heat dissipation power calculation must consider factors such as the temperature, material, and size of the excrement collection and processing device. The actual heat dissipation power will be greater than the heat dissipation power directly corresponding to heating the excrement. Conversely, if the eco-toilet is in an extremely hot environment, the temperature inside will inevitably be as high as the ambient temperature. Again, considering factors such as the temperature, material, and size of the excrement collection and processing device, the actual heat dissipation power will be less than the heat dissipation power directly corresponding to heating the excrement. This means that a temperature at which microorganisms can function, achieving the purpose of decomposing the excrement, can be reached with minimal or no heating.

[0079] In practical implementation, in the technical solution proposed in this application, solar thermal energy: Assuming a maximum solar radiation intensity of 900 W / m 2 Direct sunlight, 100% absorption rate. Total heat dissipation power 900 1.17 0.78 = 821W.

[0080] For example, if the temperature is very low, the excrement is urine, assuming 0.75m 3 Half of, 0.375m3 If urine is at 0°C (ice), and all the heat is transferred to the urine to liquefy it, 375 kg of water would need to be sun-dried. 334kJ / kg / 821W 1000J / kJ / 3600s / h=42h Furthermore, assuming 0.75m 3 Half of, 0.375m 3 If the urine temperature is 0℃ (ice), and all heat is transferred to the urine without considering heat dissipation, allowing it to liquefy, and the heating element has a power of 60W, then the working time would be: 375kg 334kJ / kg / 60W 1000J / kJ / 3600s / h=580h Considering environmental impacts, such as soil: Heat dissipation power = External heat dissipation – Urine thermal conductivity The thermal conductivity of dry soil is typically between 0.25 and 0.35 W / (m²). The thermal conductivity of HDPE is approximately 0.4-0.5 W / (m²). K); Assuming a soil thickness of 0.5m, urine temperature of 10℃, air temperature of -10℃, and the outer casing (collection and treatment device or other) has an area of ​​approximately 2m². 2 ; Heat dissipation power QL=2m 2 20 C 0.35W / (m K) / 0.5m=28W; External heat dissipation – cold air carries away heat; To sustain the reaction, a continuous supply of cold air is required. Assume the cold air temperature is -10°C, the airflow velocity is 1 m / s, the orifice diameter is 0.1 m, and the air volumetric flow rate is 0.1 m / s. 0.1 pi / 4 1m 3 / S, mass flow rate 0.010kg / S; Cold air flows over the surface of feces. The heat exchange is calculated according to natural convection heat exchange. The feces are equivalent to a 1 square meter flat plate. The feces are 10℃ and the average temperature difference is 16℃. According to Newton's law of cooling, the heat dissipation is ~80W; When the air carries away heat, the temperature change is 80 / 1005 / 0.01 = 8℃, and the outlet temperature is -2℃; If natural convection is not followed, and the airflow speed is relatively high, it will be 5 m / s. Ignoring other heat dissipation, when the outdoor temperature is -10℃, the temperature of urine and feces is 0 degrees, and the total heat dissipation power is 108W. When the outdoor temperature drops further to -20℃, the heat dissipation power is 162W. When the wind is strong, the heat dissipation power can reach as high as 500W.

[0081] The heat released during the aerobic decomposition of feces Assumption: The heat released by the aerobic decomposition of feces is 15kJ / g. If 1kg of new feces is produced every day, the heat released by decomposition in one day is also 15000kJ. Heat released: 15,000,000 / 24 / 3600 = 173 W; In reality, the aerobic decomposition time is about 20 days, and the heat dissipation power is 173 / 20=8.6W; After 20 days of accumulated feces form a cycle, 20kg of feces are reacting, and the heat dissipation power reaches 173W. A computational model was established based on parameters such as heat dissipation power, heat carried away by external air, and heat generated by the excrement itself. Through this model's calculations, the relationship between heat dissipation and heat generation can be determined, thus achieving a thermal equilibrium state. Simultaneously, this model also considers key factors such as soil contact heat dissipation, thermal resistance calculation, and the impact of airflow on heat dissipation. To improve decomposition efficiency, it is recommended to reduce the surface area of ​​contact between cold air and excrement. Furthermore, this study explores the possibility of combining solar thermal technology and solar power generation technology, and analyzes the potential challenges in terms of cost, complexity, and reliability that these technologies may bring.

[0082] Step 24: After decomposing the excrement, when it is determined that the temperature inside the eco-toilet is lower than the first threshold and / or the brightness outside the eco-toilet is lower than the first set value, the temperature of the collection and treatment device in the eco-toilet is maintained at the set temperature value.

[0083] In this step, to ensure that the temperature inside the eco-toilet is sufficient to prevent the excrement from freezing, if the temperature inside the eco-toilet is detected to be too low after the excrement is decomposed, the heat dissipation power can be adjusted to maintain the temperature of the collection and treatment device within the preset temperature range.

[0084] In this step, to ensure that the temperature inside the eco-toilet is sufficient to prevent the excrement from freezing, if the temperature and light in the eco-toilet are very low after the excrement is decomposed, such as in polar night regions, the temperature of the collection and treatment device can be maintained within a preset temperature range by adjusting the heat dissipation power.

[0085] In this application, the physical properties of the ecological toilet include at least one of the following: The size of the eco-toilet should be taken into account when calculating the heat dissipation power. If the eco-toilet is large, the heat dissipation power required for heating will also be large.

[0086] The height of the collection and processing device above the ground in an eco-toilet; The dimensions of the collection and processing devices in an eco-toilet; The material of the collection and processing device in an eco-toilet; The shape of the collection and processing device in an eco-toilet.

[0087] In practice, if a containment space is further connected to the collection and processing device, the physical properties of the containment space, such as its size, material, and shape, can be further considered when calculating the heat dissipation power. These physical properties can all affect the level of heat dissipation power.

[0088] In a preferred embodiment, the technical solution proposed in this application uses a solar collector to collect solar energy, store thermal energy, and then convert this thermal energy to provide energy for the ecological toilet. The system heat calculation includes calculations of the solar heat pipe's heat absorption, self-heating, and the heat required to maintain the system at a specified temperature.

[0089] In practice, the heat absorption calculation of solar heat pipes can comprehensively consider multiple factors, including solar radiation, heat loss of the heat pipe, net power output of the heat pipe, and environmental conditions. For details, please refer to the main steps and relevant formulas of heat absorption calculation: Heat absorption calculation for solar heat pipes: The heat absorption of a solar heat pipe primarily comes from solar radiation. The absorbed power of the heat pipe can be calculated using the following formula: Qabs=α I A In the above formula, Qabs is the absorbed solar radiation power (in W), α is the absorptivity of the heat pipe surface, which is usually between 0.9 and 0.96, I is the solar radiation intensity (in W / m²), which is about 1000 W / m² under sunny conditions, and A is the heat absorption area of ​​the heat pipe (in m²), which is usually the projected area of ​​the outer surface of the heat pipe.

[0090] Heat loss of heat pipe During operation, heat pipes dissipate heat to the environment through radiation, convection, and conduction. Heat loss can be estimated using the following formula: Qloss=ULT A (Tabs Tenv) In the above formula, Qloss is the heat loss power (in W), ULT is the average heat loss coefficient (in W / (m²·℃)) which can be determined experimentally, Tabs is the heat pipe surface temperature (in ℃), and Tenv is the ambient temperature (in ℃).

[0091] Net output power of heat pipe (Qnet) The net output power of a heat pipe is the absorbed solar radiation power minus heat loss: Qnet=Qabs Qloss In practice, self-heating calculation involves multiple steps, which may include, but are not limited to, calculating the volume of the equipment, determining the self-heating capacity, and converting the self-heating capacity into emission power. First, the equipment volume is calculated based on the external dimensions of the equipment container, and its unit is liters. Second, the determination of the self-heating capacity is based on the amount of heat absorbed by the contents for every 1°C increase in temperature, thus yielding the total heat dissipated by the entire volume of material under specific conditions, measured in kilocalories.

[0092] Calculation of the amount of heat required for the system to maintain the specified temperature In practice, the amount of heat required to maintain the material's temperature is calculated based on the effective volume of the equipment. The amount of heat required to raise the temperature by 1°C is multiplied by the volume (liters), expressed in kilocalories. The success rate is then calculated based on the heat output. If the heat pipe power + self-heating power > the required heat dissipation power, the system can maintain the temperature; otherwise, the temperature will gradually decrease.

[0093] Optionally, in the technical solution proposed in this embodiment, when it is detected that the temperature inside the eco-toilet has dropped below a second threshold, and it is confirmed that the activity status of one or more objects inside the eco-toilet has changed, the current activity status of the objects and the new area to which they belong will be reassessed. Based on the pre-set correspondence between activity status and temperature requirements, the required temperature standard for the new area will be determined; then, based on these temperature requirements, the required heat dissipation power for the new area will be calculated.

[0094] The activity status includes any one of leaving, standing up, or walking; the new area includes each area outside and inside the eco-toilet, such as the area where the toilet was originally used, the area near the toilet, the area near the door, the area near the corner, etc. These areas have different temperature requirements, and there are no specific restrictions on the specific division.

[0095] Preferably, when it is determined that the activity status is leaving the ecological toilet and being outside the ecological toilet for more than a set time, the temperature requirement of the ecological toilet is reduced according to the pre-set correspondence between the activity status and the temperature requirement.

[0096] Preferably, the activity state includes squatting; the new area includes the range set by the collection and treatment device; when it is determined that the activity state is squatting and the area is within the range set by the collection and treatment device, the temperature requirement of the eco-toilet is adjusted upwards according to the pre-set correspondence between the activity state and the temperature requirement. In this scenario, it is suitable for ensuring that the ambient temperature of the eco-toilet is at a suitable temperature when the user is using the toilet. In practice, the amount of heat required to maintain the temperature of the new area can be determined based on the temperature requirements, and the heat can be converted into heat dissipation power, which is then used as the heat dissipation power of the new area.

[0097] The internal area of ​​the ecological toilet is divided into interconnected sub-regions A1, A2, ..., An, and the thermodynamic properties of each region are defined: Heat capacity C i (J / ℃) Thermal resistance R ij (℃ / W, thermal resistance between regions i and j) HVAC equipment heating / cooling power range [ , ] Dynamic model of heat transfer Establish the discrete-time state-space equations: In the above equation,

[0098] Feasible temperature set calculation: 1. Constraint Definition User requirement constraints: ,in, It is the set temperature, the target temperature (unit: °C) set by the user for the sub-area, usually based on human thermal comfort (such as ASHRAE standards) or specific scenario requirements (such as constant temperature in a laboratory).

[0099] Equipment capacity constraints: ,in, This refers to the circuit / pipeline load-bearing capacity (such as conductor cross-sectional area and refrigerant flow rate). This is the minimum stable operating power of the equipment. The equipment in this application can be any device in an ecological toilet, such as pipes, sensors, etc.

[0100] Thermodynamic coupling constraints: preventing temperature gradients between regions from exceeding a threshold. T max。

[0101] 2. Feasible solution generation method Centralized optimization: Construct a mixed-integer programming model to solve for the set {T1,...,Tn} that satisfies all constraints. Distributed search: Derive feasible device power combinations by reverse engineering through heat conduction simulations (such as the finite element method).

[0102] Then, through target optimization and condition compensation, regional heating is achieved.
