Description

Technical Field

[0001] This application relates to the technical field of gas monitoring, and in particular to a gas management system Background Art

[0002] Gas is widely used as an essential energy source in daily life. However, as a flammable gas, gas leakage can easily cause explosions, so users usually install gas alarm devices at home to prevent gas leaks. For special groups such as "elderly people living alone", there are solutions in related technologies to reduce the alarm threshold to reduce gas accidents. However, simply lowering the gas alarm threshold is prone to false alarms due to other interference factors, making the gas alarm device unable to play its due alarm role.

[0003] In this regard, it is necessary to provide a technical solution to solve the problem of high gas accident rate among some special groups existing in relevant technologies, and to provide accurate and timely gas leakage warnings to special groups. Summary of the invention

[0021] The present application will be described in detail below in conjunction with the specific implementation modes shown in the accompanying drawings, but these implementation modes do not limit the present application. Structural, methodological, or functional changes made by ordinary technicians in the field based on these implementation modes are included in the protection scope of the present application.

[0022] like Figure 1 As shown, the present application provides a gas management system, including a gas detection module, an alarm module, a threshold adjustment module, a mode switching module, a user type judgment module, and a gas equipment usage status judgment module.

[0023] The gas detection module is installed in a selected position to monitor the gas concentration in the selected area. Exemplarily, the gas detection module includes a gas detector and a gas monitor. The gas detector is installed in the selected area to monitor the gas concentration in the selected area. The gas monitor is used to obtain the monitored gas concentration. The alarm module alarms when the gas concentration reaches a preset gas alarm threshold. Furthermore, the system may include a cut-off module, which is used to close the gas valve when the alarm module alarms to ensure user safety.

[0024] Furthermore, in the gas management system provided in the present application, a threshold adjustment module is used to adjust the gas alarm threshold; A mode switching module, comprising a first mode and a second mode, wherein in the first mode, the threshold adjustment module adjusts the gas alarm threshold to a first gas alarm threshold, and in the second mode, the threshold adjustment module adjusts the gas alarm threshold to a second gas alarm threshold or a third gas alarm threshold, wherein the first gas alarm threshold is greater than the second gas alarm threshold, and the second gas alarm threshold is greater than the third gas alarm threshold; a user type determination module, in response to determining that the current user belongs to the non-marked type group, configuring the mode switching module to the first mode; in response to determining that the current user belongs to the marked type group, configuring the mode switching module to the second mode; The gas equipment usage status judgment module is used to judge whether the gas equipment is working. In response to judging that the current user belongs to the marked type of people and the gas equipment is in a working state, the threshold adjustment module adjusts the gas alarm threshold to the second gas alarm threshold; in response to judging that the current user belongs to the marked type of people and the gas equipment is in a non-working state, the threshold adjustment module adjusts the gas alarm threshold to the third gas alarm threshold.

[0025] Specifically, Figure 2 As shown, it shows a gas alarm threshold configuration flow chart provided in an embodiment of the present application. The user type determination module determines whether the user belongs to the marked type group.

[0026] If the user type judgment module determines that the user is a non-marked type user, the mode switching module is configured to the first mode. In the first mode, the threshold adjustment module configures the gas alarm threshold of the alarm module to a normal level. This application defines the gas alarm threshold of the normal level as the first gas alarm threshold.

[0027] If the user type determination module determines that the user is a marked type user, the mode switching module is configured to the second mode, providing a lower level of gas alarm threshold setting options. Through the above settings, the modes and gas alarm thresholds of non-marked type users and marked type users are distinguished, thereby providing timely gas leak warnings for marked type users, providing more sufficient response time for marked type users and other related processing personnel, and effectively reducing the gas accident rate.

[0028] like Figure 2 As shown, further, in the second mode, the gas equipment usage status judgment module obtains the real-time usage of the kitchen gas equipment and determines whether the gas equipment is being used. If the user is using the gas equipment, the threshold adjustment module adjusts the gas alarm threshold to the second gas alarm threshold. If the user is not using the gas equipment, the threshold adjustment module adjusts the gas alarm threshold to the third alarm threshold. Among them, the second gas alarm threshold is greater than the third alarm threshold.

[0029] According to the above description, the gas management system provided by the present application provides a gas alarm threshold option lower than the normal level when facing the marked type population, so as to ensure the timeliness of the gas leak warning and provide more sufficient response time for the marked type population and other related processing personnel. In addition, according to the use status of the gas equipment, the gas alarm threshold is dynamically adjusted in the gas alarm threshold option lower than the normal level, so as to ensure the timeliness of the gas leak warning for the marked type population while reducing the false alarm rate of the gas alarm.

[0030] Specifically, in the first mode, the threshold adjustment module sets the gas alarm threshold of the alarm module to the first gas alarm threshold (for example, the first gas alarm threshold can be set to 10%LEL). Non-marked type people are users who have no special needs and can make timely feedback when the alarm module alarms. 10%LEL is the conventional alarm setting for household gas alarms. When it is for non-marked type people, the gas alarm threshold of the alarm module is set to 10%LEL, which can provide timely and effective gas leak alarms and avoid erroneous triggering of gas warnings due to slight gas fluctuations.

[0031] Furthermore, when the marked type people are not using gas equipment, the threshold adjustment module sets the gas alarm threshold of the alarm module to the third gas alarm threshold (for example, the threshold interval set by the third gas alarm threshold is greater than or equal to 3%LEL and less than or equal to 5%LEL). When the non-marked type people are not using gas equipment as users, the threshold adjustment module adjusts the gas alarm threshold of the alarm module to 5%LEL. 5%LEL is 1 / 20 of the lower explosion limit of combustible gas. Setting the gas alarm threshold to 5%LEL can provide an early alarm when the gas concentration is low. It can also leave more sufficient response time for the marked type people during inactive periods such as rest and nighttime, provide earlier safety reminders, and effectively prevent potential gas leakage risks.

[0032] Furthermore, when the marked type people use the gas equipment, the threshold adjustment module sets the gas alarm threshold of the alarm module to the second gas alarm threshold (for example, the threshold interval set by the second gas alarm threshold is greater than or equal to 6%LEL and less than or equal to 9%LEL). When the unmarked type people use the gas equipment as users, the threshold adjustment module adjusts the gas alarm threshold of the alarm module to 8%LEL, and the gas alarm threshold is set to 8%LEL, which is slightly higher than the third gas alarm threshold but less than the first gas alarm threshold. This gas alarm threshold is applicable to the situation when the gas equipment is in normal use, to avoid minor leaks or gas concentration fluctuations caused by the use of the gas equipment causing false alarms of the alarm module. By setting the second gas alarm threshold, it can provide effective early warning to the marked type people when the actual gas leakage exceeds the safety range, and avoid false alarms of the alarm module caused by the use of the gas equipment.

[0033] like Figure 1 As shown, as an optional implementation method, the gas management system also includes an information retrieval module. According to the registration information left by the user when registering the system, the information retrieval module obtains the user's type and resident personnel information, such as the user's age, health status, and emergency contact. The user type judgment module can determine whether the current user belongs to the marked type population by analyzing the information obtained by the information retrieval module. Clarifying and distinguishing user types facilitates the threshold adjustment module to set the corresponding gas alarm threshold according to the user type.

[0034] As an optional implementation, the gas management system provided by the present application further includes an image acquisition module for acquiring images of a selected area. The user type determination module is further configured to: determine the activity characteristics of the current user based on the area images acquired by the image acquisition module.

[0035] If it is determined that the current user meets the single-person activity characteristics and the registered age of the current user is greater than the preset age threshold, then the current user is determined to belong to the marked type population, wherein the registered age of the user is obtained based on the household information.

[0036] Specifically, by analyzing the collected images, we can obtain information such as the frequency of users entering the collection area, time distribution, and number of active people, and based on this information, we can judge the activity characteristics of the current user. For example, we can judge the proportion of the number of days of single-person activity within a preset period (such as within a week) within the preset period. If the proportion is greater than the preset proportion threshold (such as the number of single-person activity days is greater than three days), then we judge that the current user meets the single-person activity characteristics. At this time, if the registered age of the current user is greater than the preset age threshold (such as 70 years old), then we judge that the current user belongs to the marked type population.

[0037] As an optional implementation, the user type determination module is further configured to: analyze the portrait information in the regional image acquired by the image acquisition module, and determine the age range of the active person in the acquisition area of ​​the image acquisition module based on the portrait information. If it is determined that the current user meets the single-person activity characteristics, and the age range of the active person obtained based on the regional image analysis meets the preset age range (for example, if the preset age range is greater than 70 years old, and the age range of the active person obtained based on the image analysis is greater than 80 years old, then it meets the preset age range), then it is determined that the current user belongs to the marked type population.

[0038] As an optional implementation method, the registered age and the age based on image analysis can be mutually verified and supplemented to avoid inaccurate user labeling due to discrepancies between the registered user and the actual user (for example, if the registered user is a relative of the actual user, the registered age may be that of a young person, but the actual user is an elderly person).

[0039] As another optional implementation, the user type judgment module can combine the collected image with the usage period of the gas device, and use the usage period of the gas device to assist in analyzing whether the current user belongs to the marked type of people. Specifically, the user type judgment module is configured to obtain the usage period of the gas device, and align the usage period of the gas device with the timestamp of the regional image. The user type judgment module determines whether there is only a single person activity during the usage period of the gas device based on the regional image corresponding to the usage period. If so, it is determined that the current user meets the single person activity characteristics.

[0040] In some embodiments, the gas device used by the user is a smart gas device, which can monitor and report its own usage status. The user type judgment module can use the information retrieval module to call the information reported by the smart gas device to obtain the usage period of the gas device.

[0041] In other embodiments, the user type determination module may also determine the current user's gas equipment usage period by using the gas flow change in the absence of a gas leak alarm. In other embodiments, the user type determination module may also use image analysis to analyze the selected area image acquired by the image acquisition module to obtain the gas equipment usage period.

[0042] According to the above description, the gas management system provided by the present application uses the usage period of the gas equipment to assist in judgment, analyzes the images collected in the selected area during the usage period of the gas equipment, and determines whether there is only single-person activity at this time. If so, it is determined that the current user meets the characteristics of single-person activity, and it is necessary to further determine whether the registered age of the current user is greater than the preset age threshold, so that the system can determine whether the user needs to be included in the marked type population.

[0043] As an optional implementation method, the user type judgment module can also analyze: whether there is regularity in the user's use of gas equipment within a preset period (such as usage duration, usage period, usage duration, etc.); if there is regularity, and the kitchen activities are performed by one person during use, it is judged that the resident meets the characteristics of living alone, and the second mode of the system can be enabled.

[0044] For example, if a resident uses a gas stove from 11:00-11:30 and 17:00-17:30 every day of the week, and each time is a fixed duration of 30 minutes, it is judged that the resident's use of gas equipment is regular. Cross-analyze the kitchen activity records and the use of gas equipment. If there is only one resident in the kitchen during the time period when the gas equipment is used, it is judged that the resident meets the characteristics of living alone.

[0045] As an optional implementation, the user type determination module is further configured as follows: Acquire a regional image within a preset period, and based on the regional image, count the proportions of the current user's multi-person activity days and single-person activity days within the preset period respectively; if the proportion of multi-person activity days is lower than a first preset proportion threshold, and the proportion of single-person activity days is higher than a second preset proportion threshold, then determine that the current user meets the single-person activity characteristics, wherein the first preset proportion threshold is less than the second preset proportion threshold.

[0046] Specifically, Figure 3 As shown, in this embodiment, if the user is a non-marked type of person, a preset period is set (each week in the embodiment of the present application), and images in the selected area are collected by the image acquisition module during each preset period to obtain the frequency and number of users entering the selected area during the preset period.

[0047] Furthermore, a first preset proportion threshold (e.g., two days) and a second preset proportion threshold (e.g., five days) are set. If the proportion of multi-person activity days within the preset period is less than the first preset proportion threshold, and the proportion of single-person activity days is greater than the second preset proportion threshold, the user type judgment module confirms that the current user meets the single-person activity characteristics. As an optional implementation method, the user type judgment module periodically judges (e.g., weekly or monthly) whether the user belongs to the marked type population. By periodically judging the user type, the user type status can be updated in real time, the alarm threshold can be adjusted for the user who changes the type, and the frequency of false alarms of the alarm module can be reduced.

[0048] In order to further illustrate the gas management system provided in the embodiment of the present application, the following is an explanation in combination with the control process of the gas management system. Figure 4 As shown, including: Determine whether the current user belongs to the marked type population. If the current user is determined to be a non-marked type population, the system enters the first mode and sets the alarm threshold to the first gas alarm threshold of the conventional level. If the current user is determined to be a marked type population, the system enters the second mode and provides a lower level of gas alarm threshold options (including the second gas alarm threshold and the third gas alarm threshold, the second gas alarm threshold is greater than the third gas alarm threshold).

[0049] For the marked type population, under normal circumstances, the alarm threshold is set to the third gas alarm threshold. The gas detection module obtains the gas concentration in the monitoring environment, and in response to the gas concentration in the environment exceeding the third gas alarm threshold, determines whether the gas equipment is working. If there is no gas equipment working, an alarm is issued and the cut-off module closes the valve, so as to promptly warn the marked type population of gas leaks. If there is a gas device working, adjust the alarm threshold to the second gas alarm threshold, and re-judge whether the gas concentration exceeds the second gas alarm threshold. If it does not exceed the second gas alarm threshold, cancel the alarm to avoid false alarms; if it exceeds, an alarm is issued and the cut-off module closes the valve, so as to promptly warn the marked type population of gas leaks and reduce the incidence of gas safety accidents.

[0050] like Figure 5 As shown, as an implementation method, the gas management system also includes a data transmission module. The data transmission module is configured to synchronize the gas alarm information to the smart wearable device, triggering the smart wearable device to issue a gas alarm prompt. The gas alarm information is quickly conveyed to the user through the smart wearable device and the data transmission module, thereby improving the user's response efficiency when a gas alarm occurs and ensuring the user's safety.

[0051] Furthermore, the gas management system also includes an emergency response module. When the gas alarm prompt is triggered, the smart wearable device monitors the vital signs information of the marked type users. The data transmission module receives the user's vital signs information and the gas alarm processing response of the smart wearable device, and transmits it to the emergency response module. The emergency response module selects the corresponding strategy from the preset strategy library based on the user's vital signs information and whether to process the gas alarm processing result. The smart wearable device and the gas management system work together to accurately feedback the real-time status of the marked type users during the gas alarm. The emergency response module selects an appropriate solution based on the real-time status, improves the effectiveness and speed of the emergency response of relevant personnel, and provides protection for the safety of the marked type users during the gas alarm.

[0052] Specifically, the smart wearable device and the gas management system work together to process the gas alarm. When a gas alarm occurs, the smart wearable device transmits the alarm information to the marked type of users through vibration and sound for reminder. At the same time, the smart wearable device will monitor the user's vital signs including blood oxygen, blood pressure, and heart rate in real time, and synchronize the monitored vital signs to the community. The emergency response module proceeds to the next step based on the user's vital signs and whether to process the alarm information. If the user's vital signs are normal and the emergency response module receives the user's processing of the gas alarm, the community staff will be notified to contact the current user by phone. If the user's vital signs are normal, but the emergency response module has not received the user's response to the gas alarm processing, the emergency response module will notify the community staff to visit the current user. If the user's vital signs are abnormal, the emergency response module will notify the community staff and medical staff to visit the user. If the user's vital signs are abnormal, the emergency response module will notify the community staff and medical staff to visit the user. If the user does not wear the smart wearable device and the emergency response module does not receive the user's vital signs information, the emergency response module will notify the community staff to visit the current user and let the user wear the smart wearable device. If there is a gas leak and the user is not wearing a smart wearable device, the data of the smart wearable device is considered abnormal, and the emergency response module will notify community personnel to come and check. Through the above solution settings, the vital signs of users of the marked type can be quantified to ensure the life safety of the marked type of people as quickly as possible.
