Description

Technical Field

[0001] The invention belongs to the technical field of ecological equipment, and particularly relates to an ecological toilet suitable for locomotive drivers and a control method thereof. Background Art

[0002] There are mainly two forms of existing waterless toilets: bag-packing waterless toilets and ecological waterless toilets. The bag-packing waterless toilets need to consume packaging materials (such as plastic bags), which not only have higher usage costs and transportation costs, but also bring secondary pollution due to the non-degradability of plastic products. In addition, in severe cold weather, the fecal bags are prone to freezing, and their low-temperature adaptability is poor, which limits the applicable areas.

[0003] The ecological waterless toilet conducts resource-based, harmless and reduction treatment of human excrement and urine locally through the biochemical degradation of aerobic microorganisms, overcoming the defects of the bag-packing waterless toilets. At present, many ecological waterless toilets with different configurations and various structures have come out and are widely applied to places such as trains and cars.

[0004] However, in the actual application process, on the one hand, due to the filler for assisting the survival of microorganisms in the ecological toilet, dust will be generated during the stirring process, resulting in the inability to configure a humidity sensor in the ecological toilet, and it is very easy to fail due to the influence of dust. On the other hand, due to the inability to configure a humidity sensor in the ecological toilet, the survival environment of microorganisms cannot be optimized, and the biodegradation efficiency cannot be optimized, so the actual requirements cannot be met.

It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0024] Please refer to Figure 1 , an embodiment of the present invention provides an ecological toilet suitable for locomotive drivers, including a fermentation tank 1. Microbial cells are provided in the fermentation tank 1. A plurality of groups of stirring devices 2 are provided in the fermentation tank 1. A heating device (not shown) is provided at the outer bottom of the fermentation tank 1. The ecological toilet suitable for locomotive drivers further includes a high - frequency vibration generator 3 and a control component (not shown). A movable baffle 11 is provided at the center of the top 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 device 2, the heating device, the temperature sensor 4, the humidity sensor 5, and the high - frequency vibration generator 3; The movable baffle 11 is of a normally closed structure. The control component controls the movable baffle 11 to switch between the open state and the closed state according to the user's operation action. The movable baffle 11 allows the user to use it in the open state and provides a closed biodegradation environment for the fermentation tank 1 in the closed state; The high-frequency vibration generator 3 is installed on the humidity sensor 5 for cleaning the humidity sensor 5; The control component is further configured to receive the humidity sensing data of the humidity sensor 5 and the temperature sensing data of 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 corresponding stirring actions based on the optimal biological activity parameters.

[0025] Existing ecological toilets have fillers to assist the survival of microorganisms, so dust will be generated during the stirring process. If a humidity sensor is configured in an ecological toilet, it is very likely to be affected by dust and cause the humidity sensing function to fail. Therefore, technicians often do not install humidity sensors in existing ecological toilets, which results in the inability to monitor the humidity data inside the fermentation tank 1 in real time, and thus unable to accurately evaluate the optimal survival environment conditions of microorganisms, making the decomposition efficiency and decomposition effect of microorganisms inside the fermentation tank 1 unable to meet the expectations of technicians.

[0026] To solve the above technical problems, in a possible implementation manner, the existing ecological toilet is improved. On the one hand, a humidity sensor 5 is installed in the ecological toilet, and a high-frequency vibration generator 3 is installed on the humidity sensor 5 to avoid humidity sensing failure caused by dust, feces adhesion or scaling, and improve the accuracy of humidity data. During use, once it is found that the humidity sensing data of the humidity sensor 5 is abnormal, the high-frequency vibration generator 3 can be immediately started to clean it to ensure its reliable use.

[0027] In the first embodiment, the high-frequency vibration generator 3 is an eccentric wheel. When it is found that the humidity sensing data of the humidity sensor 5 is abnormal, the eccentric wheel is immediately started to run. Specifically, it is controlled to rotate at a 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, so as to realize the cleaning of the humidity sensor 5.

[0028] In the second embodiment, the high-frequency vibration generator 3 is an ultrasonic generator. In the embodiments of the present invention, in order to achieve the best cleaning effect, the output end of the ultrasonic generator is arranged facing the sensing surface of the humidity sensor 5. When it is found that the humidity sensing data is abnormal, the ultrasonic generator is immediately started to clean the humidity sensor, so as to ensure the accuracy and reliability of the humidity sensing data.

[0029] On this basis, combined with the temperature sensor arranged 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 the microorganisms according to 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, so that the activity of the microbial cells can be maintained in the best working state, thereby improving its decomposition efficiency and decomposition effect.

[0030] In the actual application process, a pressure sensor can be arranged at the side position of the movable baffle. When the pressure sensor monitors the stepping pressure, the control component drives the movable baffle to open. When the pressure sensor monitors the disappearance of the stepping pressure, it closes. Preferably, pressure sensors are arranged on both sides of the movable baffle, and the movable baffle is opened only when bilateral pressure is detected at the same time, so as to prevent the ecological toilet from being opened by mistake, prevent odor leakage, and improve its use hygiene and user experience.

[0031] After the user finishes using and leaves the current ecological toilet, at this time the control component monitors the disappearance of the stepping pressure, so it controls the movable baffle 11 to close. At this time, a closed biodegradation environment is formed in the fermentation tank 1, and the control component controls the heating device and the stirring device 2 to operate according to the temperature sensing data and humidity sensing data obtained in real time to perform the best biodegradation control.

[0032] For example, in this embodiment, the optimal living environment of the microorganisms is a temperature range of 40°C ± 2°C 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°C, 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 of the microorganisms, and 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 the microorganisms and improving its decomposition efficiency and decomposition effect.

[0033] In an embodiment of the present invention, by improving the existing ecological toilet, a humidity sensor is configured in the ecological toilet and a corresponding cleaning device is configured for it, thereby effectively ensuring the accuracy and reliability of the humidity sensor. On this basis, precise monitoring of the environment in the fermentation tank 1 is achieved, enabling the microorganisms to maintain the best working state, effectively improving the decomposition efficiency and effect of biodegradation, and meeting the actual needs of users.

[0034] In the actual application process, maintaining the living environment in the fermentation tank 1 at the best environment for a long time will lead to the long-term consumption of microorganisms and the fillers therein, reducing the service life of the ecological toilet, especially reducing its usage effect at the end of the service life.

[0035] To solve the above technical problems, in an embodiment of the present invention, a blower (not shown) is further provided beside the fermentation tank 1, and the control component is further configured to: obtain the working state of the microbial cells; in the case where the working state is the decomposition state, determine a first target humidity based on the optimal biological activity parameters, and control the blower to perform a first air supply / ventilation action according to the humidity sensing data and the first target humidity; in the case where the working state is the rest state, determine a second target humidity, and control the blower 3 to perform a second air supply / ventilation action according to the humidity sensing data and the second target humidity.

[0036] In an embodiment of the present invention, the control component performs real-time control on the humidity in the fermentation tank 1. Specifically, the working state of the microbial cells is obtained in real time. If it is in the decomposition state, that is, at this time the user has just excreted and immediate biodegradation is required. Therefore, the first target humidity can be determined according to the optimal biological activity parameters. For example, the first target humidity is preferably 55% ± 2%. If the humidity sensing data is greater than 57% at this time, the control component controls the blower to start and ventilate (that is, perform the air supply / ventilation action) 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 blower to stop running to maintain the humidity in the fermentation tank 1 until the humidity sensing data meets the first target humidity range.

[0037] In the second embodiment, the control component monitors that it is currently in the rest state, that is, there is no excrement that needs to be decomposed by the microbial cells at this time. Therefore, the corresponding second target humidity can be determined according to the humidity required for their lowest survival activity. The second target humidity is preferably 40% ± 2%. Then, the blower is controlled to perform the corresponding second air supply / ventilation action to force the microbial cells in the fermentation tank 1 to be in a low biological activity state, improve their survival life, reduce the consumption of the filler, and improve the overall service life of the ecological toilet.

[0038] In the embodiment of the present invention, by dynamically regulating the humidity in the fermentation tank 1 according to the working state of the microbial cells to forcibly regulate their living environment, not only can the microbial cells have the best decomposition efficiency and effect during the working state, but also can they have the best service life, meeting the higher requirements of enterprises.

[0039] In the actual application process, the humidity sensor 5 is easily affected by dust and fails. To solve this technical problem, in the embodiment of the present invention, the control component is further configured to: monitor in real time whether there is an abnormality 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.

[0040] In a possible implementation manner, 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 set outside the fermentation tank 1. The external humidity is monitored by this externally set humidity sensor, and the humidity in the fermentation tank 1 is predicted. If it is found that the deviation between the predicted humidity and the actual humidity sensing data is greater than a certain value, it is determined that the humidity sensor 5 fails. The control component controls the high-frequency vibration generator 3 to perform high-frequency vibration cleaning. During the cleaning process, it is monitored in real time whether the data change of the humidity sensor 5 is greater than the preset change threshold. For example, it is monitored whether the change of the humidity sensor 5 within 1 minute reaches 5%. If it is greater than 5%, it can be determined that the data of the humidity sensor 5 is not yet stable and the cleaning needs to continue. Therefore, the high-frequency vibration generator 3 is controlled to continue working until the change amount of the humidity sensing data is less than or equal to the preset change threshold for at least 1 minute continuously, then it can be determined that the humidity sensor 5 has been cleaned and its humidity sensing data is also in a stable state, and the control component controls the high-frequency vibration generator 3 to stop working.

[0041] In the embodiment of the present invention, by using the high-frequency vibration generator 3 to perform high-frequency vibration cleaning on the dust or dirt attached to the humidity sensor 5, the accuracy and reliability of the humidity sensor 5 are ensured, making its detection more accurate. Furthermore, the accuracy and reliability of the environmental control in the fermentation tank 1 can be ensured, creating an optimal living environment for the microbial cells, enabling them to have the best decomposition efficiency and the highest survival life, and meeting the user requirements.

[0042] The following describes a control method for an ecological toilet provided by an embodiment of the present invention with reference to the accompanying drawings.

[0043] Please refer to Figure 2, Based on the same inventive concept, an embodiment of the present invention provides an ecological toilet control method, which is applied to the ecological toilet suitable for locomotive drivers described in the embodiments of the present invention. The ecological toilet includes a fermentation tank 1 and a stirring device 2. An activity baffle 11 is provided at the top of the fermentation tank 1, and microbial cells are provided in the fermentation tank 1. The method includes: Obtain temperature sensing data and humidity sensing data in real time; Perform temperature balance control based on the temperature sensing data and the humidity sensing data; In response to a first control instruction, perform an opening control for the activity baffle 11, where the first control instruction indicates that there is a user usage action; In response to a second control instruction, perform a closing control for the activity baffle 11. The second control instruction indicates that the user has left. Obtain the monitoring data of the microbial cells, determine the optimal biological activity parameters based on the monitoring data, and control the stirring device to perform a stirring action based on the temperature sensing data, the humidity sensing data, and the optimal biological activity parameters.

[0044] In a possible implementation manner, obtain the temperature sensing data and the humidity sensing data in the fermentation tank 1 in real time, and perform temperature balance control. For example, in the first embodiment, the user does not use the ecological toilet provided by the embodiment of the present invention, but at this time the external temperature is relatively low. For example, when the locomotive is traveling in the northern region in winter, the external environmental temperature is, for example, minus 10 degrees. At this time, the temperature in the fermentation tank 1 is lower than the set minimum temperature of 5 degrees. Therefore, immediately control the heating device to perform a heating operation to keep the temperature in the fermentation tank 1 within the survival temperature range of the microbial cells (5 - 40°).

[0045] In the second embodiment, the user has just used the ecological toilet. At this time, biodegradation operation is being carried out in the fermentation tank 1, but it is monitored that the temperature in the fermentation tank 1 has reached 35 degrees. Therefore, temporarily stop the heating operation of the heating device to avoid heating the temperature in the fermentation tank 1 above 40 degrees and avoid affecting the survival of the microbial cells.

[0046] In the third embodiment, the user is using the ecological toilet, but it is monitored that the temperature in the fermentation tank 1 is also lower than 5 degrees due to the too low external temperature. At this time, still control the heating device to perform a heating operation to ensure that the temperature in the fermentation tank 1 is within a reasonable range to preferentially ensure the survival environment of the microbial cells.

[0047] In the embodiment of the present invention, by monitoring and controlling the temperature in the fermentation tank 1 independently throughout the entire usage cycle of the ecological toilet, the survival environment of the microbial cells is effectively guaranteed, the survival of the microbial cells is avoided from being affected, and the best usage effect and service life of the ecological toilet are ensured.

[0048] After the user has finished using, the movable baffle 11 is closed. At this time, a closed biodegradation environment is formed inside the fermentation tank 1, and the environmental parameters are relatively stable. Therefore, the monitoring data of the microbial cells can be further obtained, and the optimal biological activity parameters can be determined.

[0049] In the embodiment of the present invention, biological fillers are arranged inside the fermentation tank 1. The biological fillers are used to provide a biological environment for the microbial cells. The determination of the optimal biological activity parameters based on the monitoring data includes: obtaining the configuration data of the biological fillers; estimating the consumption amount of the biological fillers 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 amount; determining the optimal temperature data and the 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.

[0050] In a possible implementation manner, first, the initial configuration amount A of the biological fillers is obtained, then the usage time B of the ecological toilet is obtained, and the consumption amount of the biological fillers is estimated. The usage time can be the effective usage time of the ecological toilet, that is, after each user excretes, its effective usage time is calculated according to a preset fixed time. For example, it is preset 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.

[0051] Specifically, the remaining amount of the fillers can be determined according to the above configuration amount and consumption amount. The more the remaining amount, the more active substances the microbial cells have, and the stronger their activity. In this case, even at a lower temperature and humidity, they can still be in a highly active working state. Therefore, the corresponding optimal temperature data and optimal humidity data can be determined. In the later stage of the use of the ecological toilet, due to the large consumption amount of the fillers and the small remaining amount, the activity of the microbial cells decreases at this time. Slightly higher temperature and humidity can further promote the enhancement of their activity, and thus the corresponding optimal temperature data and optimal humidity data are determined.

[0052] After the optimal biological activity parameters are determined, the heating device and the fan are controlled to perform corresponding coordinated control operations according to the optimal biological activity parameters, so as to dynamically maintain the temperature and humidity inside the fermentation tank 1 at the optimal survival state of the microbial cells, and maximize their working / survival effect. In the actual application process, the maximization of the decomposition efficiency of the microbial cells is not only related to the temperature and humidity of the environment, but also related to the contact degree between the microbial cells and the substances to be decomposed. The higher the contact degree, the higher the decomposition efficiency.

[0053] In an embodiment of the present 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 parameters includes: obtaining the operating data of the stirring device 2, estimating the excretion amount based on the operating data, and generating excretion estimation data; determining the optimal dehumidification efficiency based on the excretion 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 parameters.

[0054] In a possible implementation manner, the optimal bioactivity parameters further include the contact degree between the microbial cells and the excrement. During the stirring process, in order to ensure that the contact degree between the microbial cells and the excrement reaches the optimal value for each stirring, an accurate assessment of the excrement is required. Therefore, during stirring, first obtain the operating data of the stirring device, and the excretion amount can be estimated through this operating data.

[0055] In an embodiment of the present invention, estimating the excretion amount based on the operating data and generating excretion estimation data includes: obtaining the initial drive current data of the stirring device 2 in the initial state; correcting the initial drive current data based on the consumption amount to generate corrected current data; obtaining the current current data of the stirring device 2; and estimating the excretion amount based on the current current data and the corrected current data to generate excretion estimation data.

[0056] In a possible implementation manner, first obtain the initial drive current data of the stirring device 2 in the initial state. In an embodiment of the present invention, the initial state of the stirring device 2 is defined as the state when it is initially filled with complete packing and running. At this time, the initial drive current data is set to I0, for example. Then, correct the initial drive current data according to the consumption amount. For example, technicians can pre-determine through experiments how much the drive current changes per unit reduction of packing on the basis of complete packing. Thus, during subsequent use, the drive current can be corrected according to the consumption amount, that is, the drive current for stirring the current packing without excrement is obtained, and corrected current data is generated.

[0057] At this time, further obtain the current current data of the stirring device 2, compare the corrected current data with the current current data, and a current data difference can be obtained. This current data difference is caused by the additionally increased excrement. Thus, the excretion amount of the excrement can be estimated, and excretion estimation data is generated.

[0058] At this time, the optimal dehumidification efficiency can be preliminarily determined according to the excretion estimation data. For example, through big data analysis, it is determined how much moisture is contained in the excretion estimation data, and thus the optimal dehumidification efficiency can be determined. At this time, corresponding heating operations are performed according to the temperature sensing data and the optimal dehumidification efficiency, so as to achieve the optimal dehumidification effect, and the excess moisture in the excrement can be evaporated as soon as possible, enabling the microbial cells to come into full contact with the excrement, thereby further improving the biodegradation efficiency and degradation effect. On the other hand, the stirring device 2 is also controlled to perform corresponding stirring actions according to the humidity sensing data and the optimal biological activity parameters.

[0059] In an embodiment of the present invention, controlling the stirring device 2 to perform corresponding stirring actions based on the humidity sensing data and the optimal biological activity parameters includes: determining the stirring mode and stirring period of the stirring device 2 based on the humidity sensing data and the optimal biological activity parameters; controlling the stirring device 2 to perform corresponding stirring actions based on the stirring mode and the stirring period; and determining whether the deviation between the current current data of the stirring device 2 and the corrected current data is less than a preset deviation threshold; if so, using the current current data as the new corrected current data.

[0060] In a possible implementation manner, if the humidity in the fermentation tank 1 is too high, the stirring speed of the stirring device 2 is controlled to be appropriately reduced to slow down the moisture evaporation and maintain the humidity in the fermentation tank 1; if the humidity in the fermentation tank 1 is too low, the stirring speed of the stirring device 2 is controlled to be appropriately increased to accelerate the moisture evaporation and maintain the humidity in the fermentation tank 1, so that the microbial cells are in the optimal biological activity environment and the optimal biodegradation effect is achieved. Specifically, if the optimal humidity in the optimal biological activity parameters is 50%, when the humidity sensing data is greater than 70%, the stirring device 2 starts the intermittent stirring mode; when the humidity sensor data is less than 45%, the stirring device 2 starts the continuous stirring mode; when the humidity sensor data is within the optimal humidity data range, the stirring device 2 operates in the intermittent stirring mode for 30 seconds and stops for 10 seconds.

[0061] However, in the actual application process, there may be a deviation between the actual excrement and the estimated excrement. For example, although the calculated excretion amounts are all 100 g, there are significant differences in the water content of pure urine, loose stools, normal stools, and dry stools, and the corresponding stirring control methods should also be significantly different to achieve the optimal biodegradation performance, otherwise there will be a huge deviation.
