Description

Technical Field

[0001] The present invention relates to the technical field of toilet gas monitoring and processing, and specifically to a smart toilet gas monitoring and processing system and method. Background Art

[0002] In modern society, public toilets are an indispensable infrastructure in daily life, with high frequency of use and strict environmental requirements. However, public toilets usually face problems such as excessive ammonia, hydrogen sulfide, methane, carbon monoxide, carbon dioxide and odor, as well as poor air quality, which directly affect the user experience and health. Traditional toilet ventilation and gas treatment methods mostly rely on mechanical ventilation or natural ventilation in fixed time periods, lack intelligent management, and cannot be effectively adjusted according to real-time conditions, resulting in low ventilation efficiency and high energy consumption. At the same time, it is difficult to comprehensively solve the problems of toilet odor and harmful gases.

[0003] With the development of Internet of Things technology, sensor technology and intelligent control technology, smart toilet systems have gradually become popular. These systems have achieved dynamic management of air quality through real-time monitoring of gas concentration in toilets combined with intelligent control methods, significantly improving the environmental quality of public toilets. However, the current more common smart toilets generally deal with abnormal gases in toilets through sensor monitoring. When it is detected that the abnormal gas concentration exceeds the standard, ventilation operations are performed. The degree of intelligence of this method is general, and generally only mechanical ventilation is performed. It does not involve the natural ventilation holes of the toilet, nor does it take into account the users in the toilet, and lacks specificity.

[0004] This article introduces a smart toilet gas monitoring and processing method. By monitoring the gas concentration at various locations in the toilet, combined with the gas flow of natural vents, and based on the position of the human body in the toilet, the ventilation strategy is dynamically adjusted to ensure continuous improvement of the air quality in the toilet.

[0102] 2. Accurately determine the gas generation position by gradually comparing and screening the gas concentration; this method can not only effectively locate the source of odor or harmful gas, but also provide a clear target for subsequent treatment, thereby improving the accuracy and efficiency of treatment; accurate positioning of the gas generation position helps to take targeted measures and reduce the waste of resources due to ineffective treatment.

[0103] 3. The processing area is obtained according to the distribution of the gas generation position, and corresponding processing is performed.

[0104] 4. By obtaining the gas flow conditions of the natural vents in the toilet, the effectiveness of the vents can be determined and the treatment strategy can be adjusted according to the direction of gas flow; this method can reduce dependence on mechanical ventilation and thus reduce energy consumption; by making full use of natural ventilation, more efficient air quality management can be achieved while reducing operating costs, which has significant economic and environmental benefits.

[0105] 5. When processing gas, the system can detect whether there is a human body in the toilet and adjust the processing strategy according to the detection results; if the presence of a human body is detected, the system will consider the position of the human body to avoid causing inconvenience or discomfort to the user, thereby improving the user experience and satisfaction; through this humanized design, the system can ensure air quality while minimizing interference and impact on users.

[0106] 6. According to the detected human body position and gas generation position, the system can flexibly adjust the processing strategy, set up processing areas and special processing areas; take different processing measures for different areas. For special processing areas, the influence of mechanical ventilation on the human body cannot be avoided, so the method of spraying odor freshener is adopted to quickly eliminate the odor. This method of flexibly adjusting the processing strategy improves the system's resilience and processing effect, ensuring that the toilet environment is always kept in the best condition.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0109] Embodiment 1:

[0110] This embodiment provides a smart toilet gas monitoring and processing method, including:

[0111] Monitor the gas concentration at various locations in the toilet and compare the gas concentration at each location with the standard threshold;

[0112] According to the comparison results, the abnormal position is obtained; the standard threshold of gas concentration is set, and the gas concentration values ​​at various locations in the toilet are detected and compared with the standard threshold. When the gas concentration at a certain location exceeds the standard threshold, the location is marked as an abnormal position; this intelligent method of identifying abnormal gas concentration helps to timely detect and deal with harmful gases in the air, prevent their accumulation and diffusion, and ensure the health and safety of users; in addition, through this automated detection and processing, the dependence on manual monitoring is reduced, and the reliability and efficiency of the system are improved.

[0113] Obtain the gas concentration of all abnormal locations and the locations of the abnormalities in the toilet;

[0114] The gas generation position is obtained according to the gas concentration of the abnormal position and the location of the abnormality in the toilet; the gas generation position is accurately determined by gradually comparing and screening the gas concentration; this method can not only effectively locate the source of odor or harmful gas, but also provide a clear goal for subsequent treatment, thereby improving the accuracy and efficiency of the treatment; accurate positioning of the gas generation position helps to take targeted measures and reduce the waste of resources due to ineffective treatment.

[0115] Detecting the presence of human body in toilets;

[0116] If no human body is detected, the processing area is obtained according to the distribution of the gas generation positions, and corresponding processing is performed. This method of dynamically obtaining the processing area improves the accuracy and effectiveness of the processing, avoids processing of unnecessary areas, and saves resources and energy.

[0117] Obtain the gas flow conditions of the natural vents in the toilet; by obtaining the gas flow conditions of the natural vents in the toilet, the effectiveness of the vents can be determined, and the treatment strategy can be adjusted according to the direction of gas flow; this method can reduce dependence on mechanical ventilation, thereby reducing energy consumption; by making full use of natural ventilation, more efficient air quality management can be achieved, while reducing operating costs, with significant economic and environmental benefits.

[0118] The first strategy is implemented according to the gas flow between the treatment area and the natural ventilation outlet;

[0119] If the presence of a human body is detected in the toilet, the location of the human body is obtained and recorded as the human body position;

[0120] According to the distribution of gas generation positions and human positions, the treatment area and special treatment area are obtained; when processing gas, the system can detect whether there is a human body in the toilet and adjust the treatment strategy according to the detection results; if the presence of a human body is detected, the system will take the human body's position into consideration to avoid inconvenience or discomfort to the user, thereby improving the user experience and satisfaction; through this humanized design, the system can ensure air quality while minimizing interference and impact on users.

[0123] The third treatment strategy is implemented for special treatment areas. According to the detected human body position and gas generation position, the system can flexibly adjust the treatment strategy, set up treatment areas and special treatment areas; take different treatment measures for different areas. For special treatment areas, the impact of mechanical ventilation on the human body cannot be avoided, so the method of spraying odor freshener is adopted to quickly eliminate the odor. This method of flexibly adjusting the treatment strategy improves the system's resilience and treatment effect, ensuring that the toilet environment is always kept in the best condition.

[0124] The step of obtaining the abnormal bit according to the comparison result includes:

[0125] Setting standard thresholds for gas concentrations;

[0126] Obtain the gas concentration values ​​at various locations in the toilet and compare them with the standard thresholds respectively;

[0127] When the gas concentration value at a certain location in the toilet is greater than the standard threshold, the location is marked as an abnormal location;

[0128] The method of obtaining the gas concentration of all abnormal positions and the positions of the abnormalities in the toilet is specifically as follows:

[0129] For each abnormal position, the maximum value of the gas concentration detected at the abnormal position is obtained as the gas concentration of each abnormal position.

[0130] The step of obtaining the gas generation position according to the gas concentration of the abnormal position and the position of the abnormality in the toilet comprises:

[0131] S1. Select an abnormal bit, record it as the first abnormal bit, and record all abnormal bits around the first abnormal bit and adjacent to the first abnormal bit as the second abnormal bit;

[0132] S2, obtaining the gas concentration of the first abnormal position, recorded as A;

[0133] S3, obtaining the gas concentrations of all second abnormal positions;

[0134] S4, comparing the gas concentrations of all second abnormal positions with A respectively;

[0135] S5. If the gas concentrations of all second abnormal positions are less than A, the first abnormal position is recorded;

[0136] S6. If there is a second abnormal position where the gas concentration is greater than A, then select another abnormal position, repeat steps S1-S6 for detection, and obtain all recorded abnormal positions;

[0137] The acquired and recorded abnormal bit is regarded as the gas generation bit.

[0151] Obtain the number of unmarked gas generation positions in each workspace again, select the workspace with the largest number of unmarked gas generation positions, and mark the gas generation positions again until all gas generation positions are marked; refer to Figure 1 , there is partial overlap between two adjacent workspaces, so the same gas generation position will exist in two workspaces. By using this method of gradually marking the gas generation positions, it can be ensured that each selected workspace contains the most gas generation positions, and then fewer workspaces are used to complete the coverage of all gas generation positions.

[0152] Get all recorded workspaces and treat each recorded workspace as a processing area.
