[0057] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0058] The embodiment of the present invention provides a carbon dioxide monitoring device based on carbon neutrality, such as Figure 1 As shown, including:

[0059] At least one carbon dioxide detection module 1 is arranged in a one-to-one correspondence at each preset position in the monitoring area;

[0060] The control module 2 is electrically connected to each carbon dioxide detection module;

[0061] The control module 2 includes:

[0062] At least one data acquisition unit 21, corresponding to the carbon dioxide detection module 1 one by one, and used to collect detection data of the carbon dioxide detection module 1;

[0063] The data processing unit 22 is electrically connected to each data acquisition unit 21;

[0064] The transmission unit 23 is electrically connected to the data processing unit 21 and is used for communication with the carbon neutrality management server;

[0065] The data processing unit 22 collects the detection data of the carbon dioxide detection module 1 through the data collection unit 21 , pre-processes the detection data, and transmits the data to the carbon neutrality management server through the transmission unit 23 .

[0066] The working principle and beneficial effects of the above technical solution are:

[0067] The carbon neutrality-based carbon dioxide monitoring device of the present invention sets the carbon dioxide detection module at the corresponding position, that is, each preset position of the monitoring area that needs to be monitored, and can also be set in the exhaust port of each working equipment; thereby monitoring carbon dioxide at each preset position, the output acquisition unit in the control module corresponds one-to-one with the carbon dioxide detection module and collects corresponding monitoring data; the data processing module pre-processes the detection data, and then generates detection data, and transmits the detection data to the carbon neutrality management server through the transmission unit; wherein the pre-processing includes but is not limited to: denoising, removal of outliers, etc.; the transmission unit includes: one or more combinations of Internet transmission module, WIFI module, 3 / 4 / 5G module.

[0068] The monitoring equipment of the present invention can accurately and effectively monitor the emitted carbon dioxide, thereby providing an important data basis for whether carbon neutrality is achieved and for formulating corresponding strategies.

[0069] In one embodiment, the data processing unit preprocesses the detection data including:

[0070] Segmented sampling of the detection data is performed based on a preset sampling time interval (for example, any value from 1 minute to 30 minutes) to obtain data segments to be processed;

[0071] Based on the preset feature extraction rules, feature extraction is performed on the data segment to be processed to obtain multiple feature values; the feature values ​​include: average value, maximum value, minimum value, the position of the maximum value in the data, the position of the minimum value in the data, etc.;

[0072] Based on multiple eigenvalues, construct a eigenvector.

[0073] After receiving the detection data (feature vector), the carbon neutrality management server integrates the feature vectors received at the same time to form a data set, and then outputs it to the preset calculation model of the corresponding monitoring area to obtain the specific emission data of the monitoring area. By extracting features, the amount of data transmitted is reduced, effectively saving the use of network resources.

[0074] In one embodiment, the carbon dioxide monitoring device based on carbon neutrality further includes:

[0075] At least one alarm module is associated with the carbon dioxide detection module in a one-to-one correspondence and is arranged next to the carbon dioxide detection module;

[0076] A vibration monitoring unit is provided in the carbon dioxide detection module;

[0077] The data processing unit also performs the following operations:

[0078] Acquire vibration data detected by the vibration monitoring unit through the data acquisition unit;

[0079] Sampling the vibration data, and determining the vibration amplitude based on the sampled vibration data;

[0080] When the vibration amplitude is greater than a preset amplitude threshold and / or the error of the difference between the vibration amplitudes of two adjacent groups is greater than a preset difference threshold, alarm data is output to the alarm module and the carbon neutrality management server.

[0081] When the vibration is greater than the amplitude threshold, the carbon dioxide detection module may have been accidentally impacted, which may have an adverse effect on the gas path and sampling gas path inside the carbon dioxide detection module. Therefore, vibration monitoring is used to ensure the safe and effective operation of the monitoring equipment and avoid failure of the detection module caused by accidental collisions and the occurrence of human adjustments.

[0082] The alarm module includes one or more combinations of an indicator light, a speaker and a buzzer.

[0083] In one embodiment, an RFID tag corresponding to the carbon dioxide detection module is provided on the carbon dioxide detection module;

[0084] An RFID card reading unit is provided in the control module;

[0085] The data processing unit locates the carbon dioxide detection module through the RFID card reading unit and the RFID tag; when the positioning is abnormal, the alarm data is output to the alarm module and the carbon neutrality management server.

[0086] RFID tags are also called radio frequency tags, transponders, and data carriers, and readers are also called readout devices, scanners, readers, communicators, and readers / writers (depending on whether the electronic tags can rewrite data wirelessly). The basic working principle of RFID technology is as follows: after the tag enters the magnetic field, it receives the radio frequency signal sent by the reader / writer, and uses the energy obtained by the induced current to send out the product information stored in the chip (Passive Tag, passive tag or passive tag), or actively send a signal of a certain frequency (Active Tag, active tag or active tag); after the reader / writer reads and decodes the information, it sends it to the management information system for relevant data processing.

[0087] The RFID system consists of two parts: the reader / writer unit and the electronic tag. The reader / writer sends electromagnetic pulses through the antenna, and the electronic tag receives these pulses and sends the stored information to the reader in response. In fact, this is a non-contact reading, writing or deleting of the data in the memory. The electronic tag contains the RFID radio frequency processing circuit and an ultra-thin antenna loop. The antenna is embedded in the tag together with a plastic sheet. The most common tag is generally the size of a credit card. Tags of different shapes and sizes can also be designed according to different application requirements.

[0088] RFID tags are divided into passive tags and active tags. Active RFID tags have a transmitter and their own power source (usually a battery). The power source is used to run the circuit of the microchip and broadcast the signal to the reader (the way a mobile phone transmits the signal to the base station). Passive RFID tags do not have batteries. They are activated by the electromagnetic wave energy emitted by the reader. In most cases, semi-active tags are often dormant and do not work. They do not send RFID signals to the outside world. The tag will only be awakened when it enters the radio frequency signal range of the reader. Normally, low-frequency and high-frequency RFID tags read tags from a range of 1 meter, while ultra-high frequency (UHF) tags read from a range of 3 to 6 meters; and RFID integrated readers with high-gain RFID antennas can increase the reading range of passive tags to 20 meters or more; therefore, the RFID reader unit can be selected according to the specific settings. The principle of RFID positioning is: the RFID reader is responsible for sending radio frequency signals and receiving information returned by the RFID tag. The position calculation algorithm calculates the specific position of the tag based on indicators such as signal strength and arrival time difference, using triangulation positioning or fingerprint positioning. Through positioning monitoring, the safe and effective operation of the monitoring equipment is guaranteed to avoid failure of the detection module caused by accidental collisions and the occurrence of human adjustments.

[0089] In one embodiment, the carbon dioxide monitoring device based on carbon neutrality further includes:

[0090] At least one trigger module, corresponding one to one with the carbon dioxide detection module, and connected to the control module for communication;

[0091] The control module also performs the following operations:

[0092] When a trigger instruction from the trigger module is received, the corresponding carbon dioxide detection module is controlled to operate.

[0093] The trigger module includes:

[0094] A first communication unit, used to connect with a controller of a detection target corresponding to the carbon dioxide detection module;

[0095] a control unit, electrically connected to the first communication unit;

[0096] A second communication unit is electrically connected to the control unit and is used for communication connection with the control module;

[0097] The control unit obtains the control data of the controller through the first communication unit; the control unit analyzes the control data and determines the trigger time point; the control unit sends a trigger instruction to the control module through the second communication unit at the trigger time point. The trigger time point is determined by a preset trigger time point determination table; that is, the control unit analyzes the control data, determines the current control instruction number, and then queries the trigger time point determination table to determine whether it is a trigger time point; the trigger time point determination table indicates whether each control instruction number corresponds to a trigger time point.

[0098] The working principle and beneficial effects of the above technical solution are:

[0099] By monitoring only after being triggered, energy waste caused by long-term monitoring equipment startup is avoided.

[0108] The controller 37 controls the gas sampling pump 36 to operate, and performs gas sampling from the area to be detected or in the pipeline, and the sampled gas enters the sample chamber 33; then, the infrared source 34 on one side of the sample chamber 33 emits infrared rays, which are absorbed by the sampled gas and detected by the detector 35. The controller 37 determines the absorption of infrared rays by the gas according to the working state of the infrared source 34 and the detection value of the detector 35; and calculates the concentration of carbon dioxide based on the absorption of infrared rays. In addition, an RFID tag can be embedded in the shell to realize positioning and identification functions; and a vibration monitoring unit is set inside to realize impact monitoring.

[0113] Analyze the monitoring parameter set and determine the upper and lower limits of monitoring;

[0114] When the monitoring value of the carbon dioxide detection module is lower than the lower limit or higher than the upper limit, an alarm message is output to the carbon neutrality management server.

[0115] After receiving the alarm information, the carbon neutrality management server performs the following operations:

[0116] Parse alarm information and determine status data sets and monitoring values;

[0117] Construct an abnormal analysis parameter set based on the status data set and the monitoring value; start a new row after the last row of data in the status data set, put the monitoring value into the first data, and set the rest of the data to the preset initial values ​​to form an abnormal analysis parameter set;

[0119] Retrieving anomaly analysis results associated with a standard parameter set that matches the anomaly analysis parameter set;

[0120] Send the abnormal analysis results to the control module;

[0121] The control module receives the abnormality analysis result and displays it through the display unit.

[0122] Among them, the working state of the detection target is obtained through each trigger module and a state data set is constructed; specifically: the trigger module obtains the device parameter data of the detection target in advance, and according to the device parameter data, the corresponding working state quantitative analysis library is called from the server, and then the control data is extracted, and the extracted features are used to construct the working state analysis parameter set, and the working state analysis parameter set is matched with the standard set corresponding to each working state quantitative value in the working state quantitative analysis library, and the matched working state quantitative value is used as the data of the corresponding position of the detection target in the state data set; the state parameter set corresponds to the carbon dioxide detection module, and each data corresponds to a detection target associated with a carbon dioxide detection module.
