Description

Technical Field

[0001] This invention belongs to the field of ecological equipment technology, and in particular relates to an ecological toilet suitable for locomotive drivers and a control method for the ecological toilet. Background Technology

[0002] There are two main types of existing flush toilets: packaged flush toilets and eco-friendly flush toilets. Packaged flush toilets require packaging materials (such as plastic bags), which not only results in higher usage and disposal costs, but also causes secondary pollution due to the non-degradable nature of plastic products. In addition, the bags are prone to freezing in cold weather, and their poor low-temperature adaptability limits the areas where they can be used.

[0003] Ecological flushless toilets utilize the biochemical degradation of human excrement by aerobic microorganisms to achieve resource recovery, harmlessness, and volume reduction on-site, overcoming the shortcomings of packaged flushless toilets. Currently, numerous ecological flushless toilets with varying configurations and structures have been developed and are widely used in trains, automobiles, and other locations.

[0004] However, in practical applications, on the one hand, because there are fillers in the ecological toilet that help microorganisms survive, dust will be generated during the mixing process, making it impossible to install humidity sensors in the ecological toilet, as they are very susceptible to dust and will fail.

[0005] On the other hand, the inability to install humidity sensors in ecological toilets makes it impossible to optimize the living environment of microorganisms and adjust the biodegradation efficiency, thus failing to meet actual needs. Summary of the Invention

[0006] In order to overcome the above-mentioned technical problems in the prior art, the present invention provides an ecological toilet and a control method for ecological toilets suitable for locomotive drivers. The method collects accurate humidity data through a humidity sensor, thereby accurately controlling the microbial environment in the ecological toilet and improving the biodegradation effect.

[0007] To achieve the above objectives, this invention provides an ecological toilet suitable for locomotive drivers, comprising a fermentation tank containing microbial cells and several sets of stirring devices. A heating device is installed at the bottom of the fermentation tank. The ecological toilet also includes a high-frequency vibration generator and a control component.

[0050] Preferably, a humidity sensor is installed in the fermentation tank, and a high-frequency vibration generator is configured on the humidity sensor. The method further includes:

[0055] The present invention has at least the following technical effects through the technical solution provided by the present invention:

[0056] By installing temperature and humidity sensors on the inner wall of the ecological toilet, the environmental conditions inside the fermentation tank can be obtained in real time. Then, the control components control the heating device to turn on / off and the stirring device to perform different stirring actions based on the optimal survival environment of microorganisms and the real-time detected environmental conditions inside the fermentation tank. This can maintain the activity of microorganisms within the optimal range, improving their decomposition efficiency and effect. Secondly, by installing a high-frequency vibration generator on the humidity sensor, measurement errors caused by dust adhesion or scaling are avoided, improving the accuracy of humidity data.

[0063] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0064] In this invention, the terms "system" and "network" are used interchangeably. "Multiple" refers to two or more; therefore, in this invention, "multiple" can also be understood as "at least two." "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / ", unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, it should be understood that in the description of this invention, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0065] Please see Figure 1 This invention provides an ecological toilet suitable for locomotive drivers, comprising a fermentation tank 1 containing microbial cells and several sets of stirring devices 2. A heating device (not shown) is provided at the bottom of the fermentation tank 1. The ecological toilet also includes a high-frequency vibration generator 3 and a control component (not shown). A movable baffle 11 is provided at the top center of the fermentation tank 1, and a temperature sensor 4 and a humidity sensor 5 are provided on the inner wall. The control component is electrically connected to the stirring devices 2, the heating device, the temperature sensor 4, the humidity sensor 5, and the high-frequency vibration generator 3.

[0066] The movable baffle 11 is normally closed. The control component controls the movable baffle 11 to switch between open and closed states according to the user's operation. The movable baffle 11 allows the user to use it when it is open, and provides a closed biodegradation environment for the fermentation tank 1 when it is closed.

[0067] The high-frequency vibration generator 3 is mounted on the humidity sensor 5 and is used to clean the humidity sensor 5.

[0068] The control component is also used to receive humidity sensing data from the humidity sensor 5 and temperature sensing data from the temperature sensor 4, determine the optimal biological activity parameters of the microbial cells based on the humidity sensing data and the temperature sensing data, and control the stirring device 2 to perform the corresponding stirring action based on the optimal biological activity parameters.

[0069] Existing eco-toilets contain fillers that aid in the survival of microorganisms, which generate dust during the mixing process. If a humidity sensor is installed in the eco-toilet, it is easily affected by dust, causing the humidity sensor to malfunction. Therefore, technicians often do not install humidity sensors in existing eco-toilets, which means that existing eco-toilets cannot monitor the humidity data inside the fermentation tank 1 in real time. Consequently, they cannot accurately assess the optimal living environment conditions for microorganisms, and the decomposition efficiency and effect of microorganisms inside the fermentation tank 1 cannot meet the expectations of technicians.

[0070] To address the aforementioned technical issues, in one possible implementation, existing eco-toilets are improved by installing a humidity sensor 5 in the eco-toilet and a high-frequency vibration generator 3 on the humidity sensor 5. This prevents humidity sensing failure caused by dust, feces adhesion, or scale buildup, thereby improving the accuracy of humidity data. During use, if any abnormality is detected in the humidity sensing data of the humidity sensor 5, the high-frequency vibration generator 3 can be immediately activated to clean it, ensuring its reliability.

[0071] In the first embodiment, the high-frequency vibration generator 3 is an eccentric wheel. When an abnormality is detected in the humidity sensing data of the humidity sensor 5, the eccentric wheel is immediately started to run. Specifically, it is controlled to rotate at high speed to generate high-frequency vibration. Since the eccentric wheel is installed on the humidity sensor 5, it can drive the humidity sensor 5 to also generate high-frequency vibration, thereby shaking off the dust and dirt on its surface, especially the sensing surface, thus cleaning the humidity sensor 5.

[0072] In the second embodiment, the high-frequency vibration generator 3 is an ultrasonic generator. In this embodiment of the invention, in order to achieve the best cleaning effect, the output end of the ultrasonic generator is set directly opposite the sensing surface of the humidity sensor 5. When an abnormality is detected in the humidity sensing data, the ultrasonic generator is immediately activated to clean the humidity sensor, thereby ensuring the accuracy and reliability of the humidity sensing data.

[0073] Based on this, combined with the temperature sensor installed on the inner wall of the ecological toilet, the temperature sensing data in the fermentation tank 1 can be obtained in real time. The control component can evaluate the optimal living environment of microorganisms based on the above sensing data, determine the corresponding control parameters according to the optimal living environment, and further control the opening / closing of the heating device and control the stirring device 2 to perform different stirring actions. This can keep the activity of microbial cells in the optimal working state, thereby improving its decomposition efficiency and decomposition effect.

[0074] In practical applications, pressure sensors can be installed on the side of the movable baffle. When the pressure sensor detects the pressure of stepping, the control component drives the movable baffle to open. When the pressure sensor detects that the pressure of stepping has disappeared, it closes. Preferably, pressure sensors are installed on both sides of the movable baffle. The movable baffle is only opened when pressure is detected on both sides at the same time. This can prevent the ecological toilet from being opened due to accidental stepping, prevent odor leakage, and improve its hygiene and user experience.

[0075] After the user finishes using the toilet and leaves, the control component detects that the pressure from stepping has disappeared and closes the movable baffle 11. At this time, a closed biodegradation environment is formed in the fermentation tank 1. The control component controls the operation of the heating device and the stirring device 2 based on the real-time temperature and humidity sensor data to achieve optimal biodegradation control.

[0076] For example, in this embodiment, the optimal living environment for microorganisms is a temperature range of 40℃±2℃ and a humidity range of 55%±2%. When the temperature sensor 4 detects that the temperature in the fermentation tank 1 is less than 38℃, the control component controls the heating device to start; or when the humidity sensor 5 detects that the humidity is greater than 70%, the control component controls the stirring device 2 to reduce the stirring speed to ensure that the temperature and humidity in the fermentation tank 1 are both in the optimal living environment for microorganisms. Then, the control component controls the heating device to maintain a constant temperature and controls the stirring speed to 25 rpm, thereby improving the working state of microorganisms and improving their decomposition efficiency and decomposition effect.

[0077] In this embodiment of the invention, by improving the existing ecological toilet, a humidity sensor is installed inside the ecological toilet and a corresponding cleaning device is provided for it, thereby effectively ensuring the accuracy and reliability of the humidity sensor. On this basis, precise monitoring of the environment inside the fermentation tank 1 is achieved, so that the microorganisms maintain the best working state, effectively improving the decomposition efficiency and decomposition effect of biodegradation, and meeting the actual needs of users.

[0078] In practical applications, maintaining the optimal living environment in fermentation tank 1 for a long time will lead to the long-term consumption of microorganisms and packing materials, reducing the service life of the ecological toilet, especially its effectiveness at the end of its service life.

[0079] To address the aforementioned technical problems, in this embodiment of the invention, a fan (not shown) is also provided beside the fermentation tank 1. The control component is further configured to: acquire the working state of the microbial cells; when the working state is a decomposition state, determine a first target humidity based on the optimal biological activity parameters, and control the fan to perform a first air supply / exhaust action according to the humidity sensing data and the first target humidity; when the working state is a resting state, determine a second target humidity, and control the fan to perform a second air supply / exhaust action according to the humidity sensing data and the second target humidity.

[0080] In this embodiment of the invention, the control component controls the humidity in the fermentation tank 1 in real time. Specifically, it acquires the working status of the microbial cells in real time. If the cells are in a decomposition state, meaning the user has just finished excreting, immediate biodegradation is required. Therefore, a first target humidity can be determined based on the optimal bioactivity parameters. For example, the first target humidity is preferably 55% ± 2%. If the humidity sensing data is greater than 57%, the control component controls the fan to start and ventilate (i.e., performs air supply / exhaust) until the humidity sensing data meets the first target humidity range. If the humidity sensing data is less than 53%, the control component controls the fan to stop running to maintain the humidity in the fermentation tank 1 until the humidity sensing data meets the first target humidity range.

[0081] In the second embodiment, the control component monitors that the system is currently in a resting state, meaning that there is no excrement that needs to be decomposed by microorganisms. Therefore, it can determine the corresponding second target humidity based on the humidity required for its minimum survival activity. The second target humidity is preferably 40%±2%. Then, it controls the fan to perform the corresponding second air supply / exhaust action to force the microorganisms in the fermentation tank 1 to be in a low biological activity state, thereby increasing their lifespan, reducing the consumption of packing material, and increasing the overall service life of the ecological toilet.

[0082] In this embodiment of the invention, by dynamically adjusting the humidity in the fermentation tank 1 according to the working state of the microbial cells, the living environment of the microorganisms is forcibly regulated. This not only enables the microorganisms to have the best decomposition efficiency and decomposition effect in the working state, but also to have the best service life, thus meeting the higher needs of enterprises.

[0083] In practical applications, the humidity sensor 5 is easily affected by dust and may fail. To solve this technical problem, in this embodiment of the invention, the control component is also used to: monitor in real time whether there are any abnormalities in the humidity sensing data collected by the humidity sensor; if so, control the high-frequency vibration generator 3 to perform high-frequency vibration operation; determine whether the data change of the humidity sensing data is greater than a preset change threshold; if the data change is less than or equal to the preset change threshold, control the high-frequency vibration generator 3 to stop working.

[0084] In one possible implementation, the humidity sensing data is monitored in real time. For example, the current humidity sensing data can be predicted based on historical big data, or another humidity sensor can be installed outside the fermentation tank 1 to monitor the external humidity and predict the humidity inside the fermentation tank 1. If the predicted humidity deviates from the actual humidity sensing data by more than a certain value, the humidity sensor 5 is determined to be faulty. The control component controls the high-frequency vibration generator 3 to perform high-frequency vibration cleaning. During the cleaning process, the data change of the humidity sensor 5 is monitored in real time to see if it exceeds a preset change threshold. For example, the change of the humidity sensor 5 within 1 minute is monitored to see if it reaches 5%. If it is greater than 5%, it can be determined that the data of the humidity sensor 5 has not yet stabilized and the cleaning needs to continue. Therefore, the high-frequency vibration generator 3 is controlled to continue working until the change of the humidity sensing data for at least 1 minute is less than or equal to the preset change threshold. Then it can be determined that the humidity sensor 5 has been cleaned and its humidity sensing data is in a stable state. The control component controls the high-frequency vibration generator 3 to stop working.

[0085] In this embodiment of the invention, a high-frequency vibration generator 3 is used to clean the dust or dirt attached to the humidity sensor 5 by high-frequency vibration, which ensures the accuracy and reliability of the humidity sensor 5, making its detection more accurate. This, in turn, ensures the precision and reliability of the environmental control within the fermentation tank 1, creating the optimal living environment for microbial cells, enabling them to have the best decomposition efficiency and the highest lifespan, thus meeting user needs.

[0086] The following description, in conjunction with the accompanying drawings, illustrates an ecological toilet control method provided by an embodiment of the present invention.

[0087] Please see Figure 2 Based on the same inventive concept, this invention provides an ecological toilet control method, applied to the ecological toilet suitable for locomotive drivers described in this invention. The ecological toilet includes a fermentation tank 1 and a stirring device 2. A movable baffle 11 is provided on the top of the fermentation tank 1, and microbial cells are placed inside the fermentation tank 1. The method includes:

[0088] Real-time acquisition of temperature and humidity sensor data;

[0089] Temperature balance control is performed based on the temperature sensing data and the humidity sensing data;

[0090] In response to a first control command, an opening control is executed for the active baffle 11, wherein the first control command indicates that a user action has occurred;

[0091] In response to a second control command, the system performs a closing control on the active baffle 11, whereby the second control command indicates that the user has left. The system acquires monitoring data of the microbial cells, determines optimal biological activity parameters based on the monitoring data, and controls the stirring device to perform a stirring action based on the temperature sensing data, the humidity sensing data, and the optimal biological activity parameters.

[0092] In one possible implementation, temperature and humidity sensor data within the fermentation tank 1 are acquired in real time, and temperature balance control is performed. For example, in the first embodiment, the user is not using the ecological toilet provided in this embodiment of the invention, but the external temperature is low, for example, a locomotive is traveling in a northern region during winter, and the external ambient temperature is, for example, -10 degrees Celsius. At this time, the temperature inside the fermentation tank 1 is 5 degrees Celsius lower than the set minimum temperature. Therefore, the heating device is immediately controlled to perform a heating operation to maintain the temperature inside the fermentation tank 1 within the survival temperature of the microbial cells (5-40°C).

[0093] In the second embodiment, the user has just finished using the ecological toilet. At this time, the biodegradation operation is underway in the fermentation tank 1. However, the temperature in the fermentation tank 1 is monitored to have reached 35 degrees. Therefore, the heating operation of the heating device is temporarily stopped to avoid heating the temperature in the fermentation tank 1 to above 40 degrees, so as to avoid affecting the survival of the microorganisms.

[0094] In the third embodiment, the user is using an ecological toilet, but due to the low external temperature, the temperature inside the fermentation tank 1 is also monitored to be below 5 degrees Celsius. At this time, the heating device is still controlled to perform heating operation to ensure that the temperature inside the fermentation tank 1 is within a reasonable range, so as to give priority to ensuring the survival environment of microorganisms.

[0095] In this embodiment of the invention, by independently monitoring and controlling the temperature inside the fermentation tank 1 throughout the entire life cycle of the ecological toilet, the survival environment of the microorganisms is effectively guaranteed, avoiding any impact on their survival and ensuring the optimal use and lifespan of the ecological toilet.

[0096] After the user finishes using the product, the active baffle 11 is closed. At this time, the fermentation tank 1 forms a closed biodegradation environment with relatively stable environmental parameters. Therefore, monitoring data of microbial cells can be obtained and the optimal biological activity parameters can be determined.

[0097] In this embodiment of the invention, a biological packing material is provided in the fermentation tank 1. The biological packing material is used to provide a biological environment for the microbial cells. The step of determining the optimal biological activity parameters based on the monitoring data includes: acquiring configuration data of the biological packing material; estimating the consumption of the biological packing material based on the usage time of the ecological toilet; determining the optimal working environment parameters of the microbial cells based on the configuration data and the consumption; determining the optimal temperature data and optimal humidity data based on the optimal working environment parameters and the monitoring data; and generating the optimal biological activity parameters based on the optimal temperature data and the optimal humidity data.

[0098] In one possible implementation, the initial configuration amount A of the biological filler is first obtained, then the usage time B of the ecological toilet is obtained, and the consumption of the biological filler is estimated. This usage time can be the effective usage time of the ecological toilet, that is, the effective usage time is calculated according to a pre-set fixed time after each user finishes excretion. For example, it is pre-set that the ecological toilet consumes 1% of A every 10 days of use. Based on the above data, the optimal working environment parameters of the microbial cells are further determined.

[0099] Specifically, based on the above configuration and consumption amounts, the remaining amount of packing material can be determined. The more remaining material, the more active substances the microorganisms possess, and the stronger their activity. Under these conditions, even lower temperatures and humidity can keep them in a highly active working state, thus allowing us to determine the corresponding optimal temperature and humidity data. In the later stages of using the ecological toilet, due to the large consumption of packing material and the small remaining amount, the activity of the microorganisms decreases. Slightly higher temperatures and humidity can further promote their activity, thus allowing us to determine the corresponding optimal temperature and humidity data.

[0100] After determining the optimal bioactivity parameters, the heating device and fan are controlled according to these parameters to perform corresponding coordinated control operations, so as to dynamically maintain the temperature and humidity in fermentation tank 1 at the optimal survival state of the microbial cells, maximizing their working / survival effect. In practical applications, maximizing the decomposition efficiency of microbial cells is not only related to the ambient temperature and humidity, but also to the contact degree between the microbial cells and the material to be decomposed; the higher the contact degree, the higher the decomposition efficiency.

[0101] In this embodiment of the invention, controlling the stirring device 2 to perform a stirring action based on the temperature sensing data, the humidity sensing data, and the optimal bioactivity parameter includes: acquiring the operating data of the stirring device 2; estimating the discharge volume based on the operating data to generate discharge estimation data; determining the optimal dehumidification efficiency based on the discharge estimation data; performing a corresponding heating operation based on the temperature sensing data and the optimal dehumidification efficiency; and controlling the stirring device 2 to perform a corresponding stirring action based on the humidity sensing data and the optimal bioactivity parameter.

[0102] In one possible implementation, the optimal bioactivity parameter also includes the contact degree between the microbial cells and the excrement. During the stirring process, to ensure that the contact degree between the microbial cells and the excrement is optimal with each stirring, the excrement needs to be accurately assessed. Therefore, during stirring, the operating data of the stirring device is first acquired, and the excretion volume can be estimated using this operating data.

[0103] In this embodiment of the invention, estimating the discharge volume based on the operating data to generate discharge estimation data includes: acquiring the initial drive current data of the stirring device 2 in its initial state; correcting the initial drive current data based on the consumption to generate corrected current data; acquiring the current current data of the stirring device 2; and estimating the discharge volume based on the current current data and the corrected current data to generate discharge estimation data.

[0104] In one possible implementation, the initial drive current data of the stirring device 2 in its initial state is first obtained. In this embodiment of the invention, the initial state of the stirring device 2 is defined as the state when it is initially filled with complete packing material. The initial drive current data at this time is set to I0, for example. Then, the initial drive current data is corrected according to the consumption. For example, technicians can determine in advance through experiments how much the drive current changes when each unit of packing material is reduced based on the complete packing material. Thus, the drive current can be corrected according to the consumption during subsequent use, that is, the drive current for stirring the current packing material without excrement is obtained, and the corrected current data is generated.

[0105] At this point, the current current data of the stirring device 2 is further obtained. The corrected current data is compared with the current current data to obtain the current data difference, which is caused by the additional excrement. From this, the amount of excrement can be estimated and excretion estimation data can be generated.

[0106] At this point, the optimal dehumidification efficiency can be preliminarily determined based on the estimated discharge data. For example, by using big data analysis, the amount of moisture contained in the estimated discharge data can be determined, thereby establishing the optimal dehumidification efficiency. Then, based on the temperature sensor data and the optimal dehumidification efficiency, the corresponding heating operation can be executed to achieve the best dehumidification effect, evaporating excess moisture from the excrement as quickly as possible. This allows the microorganisms to fully contact the excrement, further improving biodegradation efficiency and effect. On the other hand, the stirring device 2 is also controlled to perform corresponding stirring actions based on humidity sensor data and optimal biological activity parameters.

[0107] In this embodiment of the invention, controlling the stirring device 2 to perform a corresponding stirring action based on the humidity sensing data and the optimal bioactivity parameter includes: determining the stirring mode and stirring cycle of the stirring device 2 based on the humidity sensing data and the optimal bioactivity parameter; controlling the stirring device 2 to perform a corresponding stirring action based on the stirring mode and the stirring cycle; determining whether the deviation between the current current data of the stirring device 2 and the correction current data is less than a preset deviation threshold; if so, using the current current data as the new correction current data.

[0108] In one possible implementation, if the humidity in fermentation tank 1 is too high, the stirring speed of stirring device 2 is appropriately reduced to slow down water evaporation and maintain the humidity in fermentation tank 1; if the humidity in fermentation tank 1 is too low, the stirring speed of stirring device 2 is appropriately increased to accelerate water evaporation and maintain the humidity in fermentation tank 1, so that the microbial cells are in the optimal biological activity environment and achieve the best biodegradation effect. Specifically, if the optimal humidity in the optimal biological activity parameter is 50%, when the humidity sensor data is greater than 70%, stirring device 2 starts intermittent stirring mode; when the humidity sensor data is less than 45%, stirring device 2 starts continuous stirring mode; when the humidity sensor data is within the optimal humidity range, stirring device 2 can operate in intermittent stirring mode for 30 seconds and then pause for 10 seconds.

[0109] However, in practical applications, there may be discrepancies between the actual excrement and the estimated excrement. For example, although the calculated excretion volume is 100g, the water content of pure urine, loose stool, normal stool and dry stool are quite different. The corresponding stirring control methods should also be quite different to achieve the best biodegradation performance; otherwise, there will be huge deviations.

[0110] Specifically, during the stirring control process, it is also determined whether the deviation between the current current data and the correction current data of the stirring device is less than the preset deviation threshold.

Therefore, the current current data is used as the new correction current data, and a new control scheme for the stirring device 2 is generated to improve the accuracy of the stirring action, ensure that the stirring scheme matches the actual excrement decomposition effect, and improve the biodecomposition efficiency and biodecomposition effect.
