Description

Technical Field

[0001] The present invention belongs to the technical field of indoor gas safety monitoring, and in particular relates to an intelligent indoor gas safety monitoring method and system. Background Art

[0002] With the advancement of urbanization and the renovation of older residential communities, urban gas pipeline networks have become increasingly complex and densely distributed between buildings and units within each community. To ensure the safety of gas use, gas pipeline companies are continuously strengthening human, physical, and technical defenses. For example, during the cold winter months, they raise user safety awareness through publicity and training, reminding users to ensure proper ventilation when using gas stoves and gas water heaters to prevent the risks of oxygen deficiency and carbon monoxide poisoning caused by confined environments. Furthermore, they install basic gas leak detection devices to monitor potential hazards. These measures have significantly reduced the incidence of gas accidents.

[0003] However, existing gas safety monitoring methods still have many shortcomings. First, the coverage of monitoring equipment is insufficient, and the high cost of some equipment makes it difficult for many households to install it. Second, the existing monitoring system is imperfect and cannot achieve 24-hour real-time monitoring and rapid response. For example, some monitoring equipment can only detect the concentration of a single gas and cannot comprehensively monitor multiple key indicators such as carbon monoxide, oxygen, and gas components. In addition, the linkage mechanisms of existing technologies are relatively lagging and mostly rely on manual operations, such as notifying property management personnel to handle the situation. This is not only time-consuming but can also lead to untimely handling due to human factors, thus delaying the timely handling of the incident. Especially in the homes of some elderly people or those with weak safety awareness, gas accidents still occur frequently due to the lack of effective automatic monitoring and emergency response methods, posing a serious threat to the safety of residents' lives and property.

[0034] The accompanying drawings, which constitute part of this application, are intended to provide a further understanding of this application. The exemplary embodiments and descriptions of this application are intended to explain this application and do not constitute an improper limitation on this application. In the accompanying drawings:

[0035] Figure 1 Schematic diagram of a system according to an embodiment of the present invention. DETAILED DESCRIPTION

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] Example 1

[0039] In the cold winter every year, the elderly or people who do not understand the situation close or shut the doors and windows without safety awareness when taking a shower, which leads to insufficient oxygen in the house, incomplete combustion of gas, and a large amount of carbon monoxide accumulation, which can cause poisoning, coma or even death. Figure 1 As shown, this embodiment provides an intelligent indoor gas safety monitoring method, including:

[0040] S1. Real-time monitoring of indoor carbon monoxide concentration through a carbon monoxide concentration monitor;

[0041] Furthermore, the carbon monoxide concentration monitor is installed near the gas cooker or at the end of the exhaust pipe of the gas water heater, and the installation position maintains a preset distance from the ground.

[0042] Specifically, a carbon monoxide concentration monitor should be installed near gas stoves or at the end of the gas water heater exhaust pipe to monitor emissions in real time. The safety threshold for the monitor can be set to ≤50ppm, and an alarm will be issued if it exceeds 30ppm. CO has a slightly lower density than air, so the monitor should generally be installed about 1.5 meters above the ground.

[0043] In this embodiment, gas stoves and gas water heaters are the main potential sources of carbon monoxide leakage in the home. Carbon monoxide is generated when combustion is incomplete. Installing the monitor near these devices can detect leakage in a timely manner.

[0044] In this embodiment, the density of carbon monoxide is slightly lower than that of air, and it will diffuse upward after leakage. Installing it at a position about 1.5 meters above the ground can better capture the carbon monoxide that diffuses upward.

[0045] S2. Monitor the indoor oxygen concentration in real time through an oxygen concentration monitor;

[0046] This embodiment also monitors the oxygen concentration. If gas combustion occurs indoors, which consumes indoor oxygen, and the doors and windows are closed or ventilation is poor, and no fresh oxygen is supplied to the room from the outside, the oxygen concentration will continue to decrease, leading to insufficient oxygen supply for indoor personnel. The alarm device will promptly emit a sharp and rapid whistling sound and an audible and visual alarm to alert people inside and outside the room, and will also notify the property management company and property management security personnel.

[0047] In this embodiment, the gas combustion status is determined by an oxygen concentration monitor. A continuous decrease in oxygen concentration generally indicates that gas combustion has occurred indoors. Gas combustion consumes oxygen, and if the oxygen concentration continues to decrease, it indicates that the combustion process may be ongoing.

[0048] In this embodiment, ventilation conditions are monitored using an oxygen concentration monitor. If the indoor oxygen concentration decreases, it may be due to closed doors and windows or poor ventilation, preventing fresh oxygen from entering the room. In this case, people inside may be in danger due to lack of oxygen.

[0049] S3. Real-time monitoring of indoor gas component concentrations through a gas component monitor;

[0050] In this embodiment, the concentrations of the gas components butane, propane, and methane are monitored in real time by a gas component monitor. If the concentrations are increasing, it indicates that there is a risk of gas leakage or incomplete combustion.

[0051] Furthermore, the carbon monoxide concentration monitor, the oxygen concentration monitor, and the gas component monitor obtain real-time data of carbon monoxide concentration, oxygen concentration, and gas component concentration through spectral analysis technology, and have data storage and analysis functions.

[0052] S4. Electrically connecting the alarm device to the carbon monoxide concentration monitor, the oxygen concentration monitor, and the gas composition monitor, and sounding an alarm through the alarm device when abnormal concentrations are detected;

[0053] Furthermore, the alarm device includes a high-decibel alarm and an audible and visual alarm;

[0054] The alarm is equipped with a rapid and piercing whistling sound and has a networking function, which can be connected to the gas supply company's dispatch center and the security room of the residential property management center to send out alarm information;

[0055] The alarm device is installed near a gas cooker or near a bathroom.

[0056] Specifically, this embodiment selects an alarm with a high-decibel alarm + networking function. The alarm is set to have a rapid and sharp whistling sound and has sound and light alarm functions. It can be connected to the gas supply company's dispatch center and the security room of the community property management center to send alarm information. It is installed near the gas stove or inside and outside the bathroom so that people taking a bath can hear it in time.

[0057] S5. Electrically connect the linkage device to the carbon monoxide concentration monitor, the oxygen concentration monitor, and the gas component monitor. When abnormal concentrations are detected, the linkage device automatically opens the window and starts the exhaust device to increase the oxygen concentration in the room to achieve ventilation and at the same time shuts down the gas equipment.

[0058] Furthermore, when an abnormal concentration is detected, the process of automatically opening the window and starting the exhaust device through the linkage device includes:

[0059] When the alarm device sounds an alarm, the window is automatically opened for ventilation through the manipulator of the automatic window opening device in the linkage device, and the fresh air outside is automatically drawn into the room through the exhaust device in the linkage device.

[0060] Furthermore, the linkage device also includes a device for automatically shutting down the gas equipment, which automatically shuts down the gas equipment when abnormal concentration is detected.

[0061] In this embodiment, the linked control system can quickly take action when abnormal concentrations are detected, eliminating the need for manual intervention and significantly improving response speed. Automatic ventilation and gas equipment shutdown effectively reduce indoor hazardous gas concentrations, preventing poisoning or suffocation. Automated processing can also minimize fires or explosions caused by gas leaks or incomplete combustion.

[0062] Furthermore, the carbon monoxide concentration monitor determines whether the carbon monoxide concentration exceeds a preset threshold value based on the stored and analyzed data, and triggers an alarm device and a linkage device if so;

[0063] Specifically, the monitor has multiple monitoring technical means, and can obtain the real-time concentration of carbon monoxide through spectral analysis. It also has the function of storing and analyzing the result data. It can analyze that the carbon monoxide concentration is constantly increasing and has been rising. Through intelligent analysis, it is about to reach the set danger threshold, and timely issue an early warning and activate the linkage device to perform gas shut-off and ventilation operations.

[0064] To prevent further increases in concentration, which could lead to people collapsing from poisoning, this embodiment pre-installs a device that automatically opens windows if the carbon monoxide concentration is ≥70ppm, enabling immediate ventilation. Specifically, a linkage mechanism can automatically push the windows open via a manipulator, and a ventilation device can be installed to draw fresh air and oxygen into the room, replacing the air and increasing the oxygen concentration. Furthermore, a pre-installed linkage mechanism can automatically shut down gas equipment.

[0065] The oxygen concentration monitor determines whether the oxygen concentration continues to decrease based on the stored and analyzed data, and triggers the alarm device and linkage device if it decreases;

[0066] Specifically, this embodiment can monitor oxygen concentration in real time. If the oxygen concentration keeps decreasing, it indicates poor ventilation, which can easily lead to hypoxia and even coma. A warning can be issued in a timely manner and the linkage device can be activated to shut off the air and ventilate the room.

[0067] The gas component monitor determines whether the gas component concentration continues to increase based on the stored and analyzed data, and triggers the alarm device and the linkage device if it increases.

[0068] Specifically, this embodiment can monitor the concentration of gas components such as butane, propane, and methane. If the concentration continues to increase, it indicates that there is a risk of gas leakage or incomplete combustion. It will also promptly issue an audible and visual alarm and activate the linkage device to perform gas shut-off and ventilation operations.

[0069] In this embodiment, the linkage is to automatically open the doors and windows for ventilation through a robot; automatically start the exhaust fan to draw fresh air into the room, for forced ventilation. The linkage of the existing technology only notifies the property staff to come and operate, which is relatively slow and has no automatic device.

[0070] In this embodiment, the linkage automatically closes the gas supply valve, cuts off the gas supply, and self-closes the valve. However, the linkage of the prior art is to notify the property staff to manually close the valve, which is also a bit slow and delayed.

[0071] Beneficial effects of this embodiment:

[0072] This embodiment can be combined with more refined monitoring of carbon monoxide concentration to reduce or eliminate the problem that due to the cold winter, some users close doors and windows, resulting in insufficient oxygen after combustion and insufficient combustion, which leads to excessive carbon monoxide production, resulting in carbon monoxide poisoning, coma and casualties.

[0073] This embodiment uses a gas component meter to monitor the content of butane, propane, methane and other components of indoor gas in real time. If the concentration reaches a certain threshold, it can be determined whether there is a gas leak.

[0074] This embodiment uses remote control of the stop valve and the intercepting valve to promptly shut off the gas supply to gas users, thereby avoiding the occurrence or escalation of accidents.

[0075] This embodiment adds an automatic window opening function. Through the linkage device, the window is automatically pushed open and the exhaust device is started to draw external air, oxygen, etc. into the room.
