[0019] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0020] Please see Figure 1-4 This patent provides a technical solution: a carbon emission monitoring device with automatic alarm function, including a detection tube 1 and a detection component 2. The detection component 2 is installed at the upper end of the inner wall of the detection tube 1. The detection component 2 is installed at the upper end of the inner wall of the detection tube 1 and is located at a key position for gas flow. It can accurately detect the relevant parameters of the gas flowing through it. An air inlet groove 3 is opened on the outer wall of the detection tube 1, and a dustproof net 4 is installed on the inner wall of the air inlet groove 3.

[0021] The air inlet slot 3 on the outer wall of the detection tube 1 is the channel for external gas to enter the inside of the detection tube. To ensure the accuracy and stability of the detection, a dustproof net 4 is installed on the inner wall of the air inlet slot 3. The dustproof net 4 is made of fine filter material, which can effectively intercept dust, particulate matter and other impurities in the air, prevent them from entering the detection tube, prevent impurities from adhering to the detection components and affecting the detection accuracy, extend the service life of the detection components, and at the same time ensure that the gas entering the detection tube is a relatively pure sample gas that has undergone preliminary filtration.

[0022] A cleaning component 5 is installed on the upper wall of the detection tube 1. The cleaning component 5 is designed to solve the problem that dust and other impurities will accumulate on the surface of the dustproof net 4 during long-term use, affecting the air intake effect and detection accuracy. The cleaning component 5 includes a fixing ring 51, a sliding groove 52, a protrusion 53 and bristles 54. The side wall of the fixing ring 51 is provided with a sliding groove 52. The outer side wall of the detection tube 1 is provided with a protrusion 53. The protrusion 53 can be inserted into the sliding groove 52. The detection tube 1 can slide up and down inside the fixing ring 51 through the cooperation of the protrusion 53 and the sliding groove 52. The inner side wall of the fixing ring 51 is provided with bristles 54, which can fit against the side wall of the dustproof net 4.

[0023] The fixing ring 51 serves as the basic fixing component of the cleaning assembly 5. The sliding groove 52 on its side wall cooperates with the protrusion 53 on the outer side wall of the detection tube 1 to form a sliding connection structure. This design allows the detection tube 1 to slide up and down inside the fixing ring 51.

[0024] When the detection tube 1 slides, the bristles 54 installed on the inner side wall of the fixing ring 51 will fit tightly against the side wall of the dustproof net 4. The bristles 54 are made of a soft and resilient material. During the up-and-down sliding process of the detection tube 1, they can effectively clean the surface of the dustproof net 4, remove dust and other impurities attached to the dustproof net 4, ensure the air permeability of the dustproof net 4, maintain the normal ventilation function of the air inlet slot 3, and thus ensure the continuous and stable operation of the detection device.

[0025] Specifically, a shielding sleeve 6 is inserted and installed in the lower wall of the detection tube 1. The shielding sleeve 6 includes a tube body 61, a counterweight 62 and a sealing gasket 63. The tube body 61 is inserted and installed in the lower wall of the detection tube 1. The sealing gasket 63 is fitted to one end of the tube body 61. The sealing gasket 63 can fit against the upper wall of the inner cavity of the detection tube 1. The counterweight 62 is installed in the inner cavity of the tube body 61.

[0026] When the dustproof net 4 needs to be cleaned, the detection tube 1 needs to be pushed upward. When it is pushed, the shielding sleeve 6 will be inserted into the detection tube 1, and the sealing gasket 63 at its upper end can fit tightly with the upper wall of the inner cavity of the detection tube 1 to form a good sealing effect, preventing the dust from coming into contact with the detection component 2 during the dust removal process, adhering to the outside of the detection component 2, and affecting the normal operation of the detection component 2.

[0027] The counterweight 62 is designed so that after the blocking sleeve 6 is released, the blocking sleeve 6 will automatically descend, thus releasing the obstruction of the detection component 2.

[0028] Specifically, the detection component 2 includes a carbon dioxide sensor 21, a temperature and humidity sensor 22, and a data processing module 23. The carbon dioxide sensor 21 and the temperature and humidity sensor 22 are both electrically connected to the data processing module 23. The carbon dioxide sensor 21 is used to detect the concentration of carbon dioxide in the gas entering the detection tube, the temperature and humidity sensor 22 is used to detect the temperature and humidity of the gas, and the data processing module 23 is used to receive and process the data transmitted by the carbon dioxide sensor 21 and the temperature and humidity sensor 22.

[0029] The data processing module 23 uses an adaptive Kalman filter algorithm to filter the electrical signal data transmitted by the carbon dioxide sensor 21 and the temperature and humidity sensor 22. The algorithm can adjust the filtering parameters in real time according to the dynamic change characteristics of the sensor data, effectively removing white noise and random interference. Taking carbon dioxide concentration data as an example, the algorithm continuously predicts and updates the data state by establishing state equations and observation equations, accurately separating the real signal from noise, and making the data smoother and more stable.

[0030] A sensor calibration database is established to store the calibration parameters of the sensor under different environmental conditions. When the sensor data is transmitted to the data processing module 23, the corresponding calibration parameters are retrieved from the calibration database based on the current ambient temperature, humidity and other information. The original data is then linearly calibrated or nonlinearly compensated. For example, the carbon dioxide sensor 21 has different sensitivity at different temperatures. The data is corrected by the calibration parameters to improve the detection accuracy.

[0031] The least squares curve fitting algorithm was used to calculate the carbon dioxide concentration. Using the intensity of the electrical signal output by the sensor as the independent variable and the concentration of the standard gas as the dependent variable, a model relating the electrical signal intensity to the carbon dioxide concentration was established through curve fitting using a large amount of standard gas test data. In actual monitoring, the electrical signal intensity collected by the sensor in real time was substituted into this model to calculate the accurate carbon dioxide concentration value.

[0032] A temperature and humidity correction model based on multiple linear regression was constructed. Actual and measured values ​​of carbon dioxide concentration under different temperature and humidity conditions were collected experimentally. Temperature, humidity, and uncorrected measured carbon dioxide concentration were used as independent variables, and the actual carbon dioxide concentration was used as the dependent variable to establish a multiple linear regression equation. During data processing, real-time detected temperature and humidity data and measured carbon dioxide concentration values ​​were substituted into this equation to calculate the temperature and humidity corrected carbon dioxide concentration, thus reducing the influence of environmental factors on the measurement results.

[0033] The data processing module 23 has a built-in embedded database, employing a time-series database storage structure to store processed monitoring data such as carbon dioxide concentration, temperature, and humidity according to time series. Each data point includes information such as timestamp, data type, and measurement value, facilitating quick querying and analysis of historical data. Simultaneously, data storage periods and capacity thresholds are set; when the storage period or capacity limit is reached, the oldest data is automatically overwritten, ensuring continuous and efficient database operation.

[0034] The data processing module 23 communicates with the carbon dioxide sensor 21 and the temperature and humidity sensor 22 via the SPI (Serial Peripheral Interface) bus to achieve fast and stable data transmission. It periodically sends data read commands to the sensors according to the agreed data protocol format and receives the detection data fed back by the sensors.

[0035] The alarm component uses an interrupt triggering mechanism to achieve data interaction with the alarm component. When the carbon dioxide concentration calculated by the data processing module 23 exceeds the preset threshold, an interrupt signal is immediately generated, and an alarm command and related monitoring data are sent to the data processing interface in the alarm component, triggering the alarm of the sound and light alarm and the data transmission operation of the wireless communication module.

[0036] The detection component 2 is the core part of the entire device to realize the carbon emission monitoring function. Among them, the carbon dioxide sensor 21 adopts high-precision gas detection technology, which can quickly and accurately detect the carbon dioxide concentration in the gas entering the detection tube, and convert the detection data into an electrical signal and transmit it to the data processing module 23.

[0037] The temperature and humidity sensor 22 is responsible for monitoring the temperature and humidity parameters of the gas in real time, and also transmits the detected data to the data processing module 23 in the form of electrical signals.

[0038] The data processing module 23, as the data processing hub of the detection component 2, has powerful data processing and analysis capabilities. After receiving electrical signal data from the carbon dioxide sensor 21 and the temperature and humidity sensor 22, it first performs preprocessing such as filtering and calibration on the data to remove noise and interference. Then, according to the preset algorithm and model, it analyzes and calculates the carbon dioxide concentration data. At the same time, it combines the temperature and humidity data to correct and optimize the carbon dioxide concentration detection results, ensuring that the final output data can truly and accurately reflect the actual carbon emissions.

[0039] Specifically, it also includes an alarm component 7, which is electrically connected to the data processing module 23 in the detection component 2. The alarm component 7 includes an audible and visual alarm 71 and a wireless communication module 72. The audible and visual alarm 71 is used to issue an audible and visual alarm signal when the data processing module 23 determines that the carbon dioxide concentration exceeds a preset threshold. The wireless communication module 72 is used to send alarm information and monitoring data to a remote terminal.

[0040] The alarm component 7 is a key component for the carbon emission monitoring device to realize the automatic alarm function. It is electrically connected to the data processing module 23 and can receive instructions and data from the data processing module 23 in a timely manner.

[0041] The audible and visual alarm 71 uses a high-brightness light-emitting device and a high-decibel sound-emitting device. When the data processing module 23 determines that the detected carbon dioxide concentration exceeds the safety standard according to the preset carbon dioxide concentration threshold, it will immediately send an alarm command to the audible and visual alarm 71. After receiving the command, the audible and visual alarm 71 will simultaneously emit a strong flash and a loud alarm sound to intuitively remind the surrounding personnel that the carbon dioxide concentration in the current environment has exceeded the standard and that corresponding measures need to be taken.

[0042] The wireless communication module 72 uses advanced wireless communication technologies (such as 4G, 5G, or LoRa) to package alarm information (including alarm time, alarm location, and concentration exceeding the standard) and detailed monitoring data at the same time as the audible and visual alarm 71 issues an alarm signal. This data is then sent to a remote terminal (such as a computer in the monitoring center or a mobile phone of a manager) via a wireless network. In this way, even if staff are not on-site, they can obtain alarm information and monitoring data in a timely manner, enabling them to make quick decisions and take countermeasures, thus achieving remote real-time monitoring and management of carbon emissions.

[0043] Specifically, a connecting ring 8 is installed on the side wall of the fixing ring 51. The connecting ring 8 can be sleeved on the outside of the external column. The connecting ring 8 adopts a ring structure design and has a certain inner diameter size, which can be tightly sleeved on the outside of the external column (such as a monitoring rod, building column, etc.). The fixing ring 51 is firmly installed on the external column by bolts, buckles and other fixing methods, thereby ensuring the installation stability of the entire monitoring device. The outer walls of the upper and lower ends of the detection tube 1 are equipped with convex rings 9. The convex rings 9 can limit the vertical sliding distance of the detection tube 1. When the detection tube 1 slides up and down during the cleaning of the dustproof net 4, the convex rings 9 will contact the upper and lower edges of the fixing ring 51 to prevent the detection tube 1 from sliding excessively and detaching from the fixing ring 51.

[0044] Specifically, a support rod 10 is installed on the upper wall of the fixed ring 51. The support rod 10 has an L-shaped cross section. One end of an elastic telescopic rod 11 is installed below the horizontal part of the support rod 10, and the other end of the elastic telescopic rod 11 is installed on the upper wall of the detection tube 1.

[0045] The elastic telescopic rod 11 has a spring inside, which provides elastic force to the telescopic rod, thereby supporting the detection tube 1. When the dustproof net 4 is not cleaned, the convex ring 9 above the detection tube 1 will contact the upper end of the fixing ring 51, thus preventing the fixing ring 51 from blocking the detection tube 1 and affecting the airflow.

[0046] Working principle: External gas enters the device through the air inlet slot 3 on the outer wall of the detection tube 1. The dustproof net 4 on the inner wall of the air inlet slot 3 will perform preliminary filtration of the gas. The gas after preliminary filtration comes into contact with the detection component 2 and is detected by the detection component 2.

[0047] Carbon dioxide sensor 21 detects the carbon dioxide concentration in the gas in real time and converts the detection data into an electrical signal. Temperature and humidity sensor 22 simultaneously detects the temperature and humidity of the gas and also converts the data into electrical signals. These electrical signals are then transmitted to data processing module 23. Data processing module 23 analyzes and calculates the carbon dioxide concentration data according to a preset algorithm and model, and corrects and optimizes the carbon dioxide concentration detection results by combining temperature and humidity data to obtain data that accurately reflects the actual carbon emissions. Data processing module 23 compares the processed carbon dioxide concentration data with a preset threshold. If the carbon dioxide concentration exceeds the preset threshold, data processing module 23 will immediately send an alarm command to alarm component 7. At this time, audible and visual alarm 71 receives the command and emits a strong flash and a loud alarm sound to alert people in the vicinity. At the same time, wireless communication module 72 packages the alarm information and monitoring data and sends them to a remote terminal via wireless network so that relevant personnel can make timely decisions and take countermeasures.

[0048] After the device has been used for a period of time, the dustproof net 4 needs to be cleaned. When cleaning, the staff first pushes the shielding sleeve 6 upward so that it is inserted into the detection tube 1, and the sealing gasket 63 at its upper end can fit tightly against the upper wall of the inner cavity of the detection tube 1. Then, the device is pushed upward. At this time, the detection tube 1 will move upward so that its bristles 54 come into contact with the dustproof net 4 for cleaning.
