[0002] With the development of society, fire safety has received more and more attention from the society and is an important safety guarantee for the smooth operation of the whole society. In formal warehouse and factory management, if the harmful gas content is not detected, the staff may be exposed to high concentrations of harmful gases for a long time without knowing it, leading to symptoms such as poisoning, confusion and even coma, seriously threatening life and health, and increasing the risk of accidents such as fire or explosion. Therefore, it is necessary to regularly detect the harmful gas content. Through regular detection, abnormal changes in the harmful gas content can be discovered in time, so that corresponding measures can be taken, such as strengthening ventilation and timely treatment, to ensure the safety of the working environment.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0049] See also Figure 1-Figure 2 The present invention provides an intelligent data center system and method based on multi-source data collection, and the corresponding flowchart of the intelligent data center analysis method based on multi-source data collection is as follows: Figure 1 As shown. The following steps are included:

[0050] Step S1: Obtain the workplace layout drawing and the hazard source layout drawing, establish a BIM model of the workplace, and mark each hazard source in the workplace in the BIM model.

[0051] In this embodiment, the workplace is a warehouse or factory where chemicals or toxic gases are stored, the staff are personnel who inspect the warehouse or factory, the environmental gases are oxygen and harmful gases, the harmful gases include hydrogen sulfide, carbon monoxide and methane, and the hazardous source is a storage tank that can release harmful gases. The workplace layout drawing and the hazardous source layout drawing are obtained, and a BIM model of the workplace is established. The process of establishing the BIM model is a prior art, and each hazardous source in the workplace is marked in the BIM model for easy distinction. The factory environment is complex, the causes of harmful gas leakage are diverse, and the factory space is large, making it difficult to detect the source of leakage and the content of the leaked harmful gas in time. The present invention collects environmental gas parameters during the work process, including oxygen, hydrogen sulfide, carbon monoxide, and methane, by wearing a hazardous gas detector on the staff, which is installed in the staff's clothing and has the characteristics of small size; wearing a position sensor to obtain the position of the staff in real time, and the hazardous source can release harmful gases.

[0052] Step S2: According to the location of each hazardous source and the historical leakage situation, the inspection sequence of the hazardous sources is planned in the BIM model, and gas detection is performed on each hazardous source according to the inspection sequence.

[0053] Step S2-1: Obtain the number of leakages of each hazardous source in the workplace in the past [0, d] days and (d, 2d] days, and determine the inspection order and inspection frequency of each hazardous source according to the number of leakages.

[0054] According to the historical leakage of each hazardous source in the workplace, the number of leakages of each hazardous source in the workplace within the past [0, d] days and (d, 2d] days is obtained. In this embodiment, d=30. Assume that there are four hazardous sources a, b, c, and d, among which a has leaked once in the past [0, 30] days and (30, 60] days, and the hazard level is the largest, which is set to 1; b has only leaked once in the past [0, 30] days, and the hazard level is relatively large, which is set to 2; c has only leaked once in the past (30, 60] days, and the hazard level is relatively small, which is set to 3; and d has not leaked in the past [0, 30] days and (30, 60] days, and the hazard level is the smallest, which is set to 3. Then, since a has leaked in the past [0, 30] days and (30, 60] days, and the hazard level is the largest, the hazardous source a should be detected multiple times. In this embodiment, the detection times of hazardous sources a, b, c, and d are 2, 1, 1, and 1 respectively, and the detection order is a.

[0055] Step S2-2: The inspection times of each hazardous source are greater than or equal to 1, and gas detection is performed on each hazardous source according to the inspection sequence and inspection times of each hazardous source.

[0056] Step S3: The staff collects the harmful gas content value of each dangerous source in the gas detection process in real time, and marks each dangerous source with different characteristics according to the harmful gas content value. Figure 3 The structural diagram of the staff inspecting the hazardous source is shown in the following figure.

[0057] Step S3-1: The staff wears an environmental gas detector and a position sensor, wherein the effective radius of the environmental gas detector for detecting gas is r; the area with a detection radius of r centered on the staff's position is used as the detection range of the environmental gas detector; the area with a first detection radius of r centered on the hazardous source's position is used as the first gas detection range of the hazardous source.

[0058] Generally speaking, in an environment with good ventilation conditions, the effective radius of the environmental gas detector for detecting gas content is 4 meters; while in an actual environment with poor ventilation conditions, the effective radius of the environmental gas detector for detecting gas content is only 2 meters. The specific detection radius r is determined based on actual conditions.

[0059] Step S3-2: Set the warning gas content threshold to ; At any distance from the source of danger The position at that time is taken as the starting point, and the position within the first gas detection range closest to the starting point in the hazardous source is taken as the end point; if the harmful gas content value detected at the starting point is , then The value of is taken as the second detection radius R of the danger source, where , In this embodiment, =3.

[0060] Step S3-3: If the harmful gas content value detected at the starting point In the process of approaching the end point from the starting point, the distance value H from the danger source and the detected harmful gas content value F are obtained in real time, and the distance value H is used as the horizontal coordinate and the harmful gas content value F is used as the vertical coordinate to establish a content-distance coordinate system in real time, and obtain the maximum harmful gas content value in real time And the minimum harmful gas content value , will be met for the first time during the testing process The distance value at that time is taken as the second detection radius R of the danger source, k is a constant; if there is no The condition is that it is determined that the danger source has no second detection radius; in this embodiment, k=5.

[0061] Step S3-4: Perform the first characteristic marking processing on the hazardous source with a second detection radius; use the area between the distance r and R from the hazardous source as the second gas detection range of the hazardous source, and collect the harmful gas content value within the second gas detection range in real time. After the collection is completed, inspect the next hazardous source in accordance with the inspection order.

[0062] It should be noted that the step S4-1 states that the distance difference from the dangerous source collected in real time within the second gas detection range is set as ', wherein the real-time collected data is the data of 'real-time collection of harmful gas content values ​​within the second gas detection range' mentioned in step S3-4.

[0063] Step S3-5: If the hazardous source does not have a second detection radius, collect the harmful gas content values ​​of the staff within the first gas detection range in real time, and if there is a harmful gas content value greater than or equal to , perform the second characteristic marking process on the hazardous source, and collect the harmful gas content value within the first gas detection range in real time. After the collection is completed, inspect the next hazardous source in the inspection order; if there is no harmful gas content value greater than or equal to , it is judged that there is no early warning for the hazard source.

[0064] It should be noted that the step S4-1 states that the distance difference from the hazard source collected in real time within the first gas detection range is set as ', wherein the real-time collected data is the data of 'real-time collection of harmful gas content values ​​within the first gas detection range' mentioned in this step S3-5.

[0065] At this point, all the dangerous sources with dangerous degrees are marked with the first or second characteristics. In the following steps, the dangerous sources with characteristic marking are analyzed to obtain the treatment plan for each dangerous source. Among them, the dangerous source with the first characteristic marking indicates that the dangerous source has a long diffusion distance and a high degree of danger, while the dangerous source with the second characteristic marking indicates that the dangerous source has a short diffusion distance and a low degree of danger, but still poses a hazard to the human body.

[0066] Step S4: According to the harmful gas content value of each hazard source obtained in the gas detection process, the hazardous content value of each hazard source is obtained, and then each hazard source in the workplace is divided into different hazard levels.

[0067] Step S4-1: If the hazard source is subjected to the first characteristic marking process, the distance difference from the hazard source collected in real time within the second gas detection range is set as If the hazard source is subjected to the second characteristic marking process, the distance difference from the hazard source collected in real time within the first gas detection range is set as .

[0068] Step S4-2: Set the distance difference interval to b, and get distance intervals, and obtain the 1st~ The distance value of the dangerous source at each distance interval and the harmful gas content value are used to establish a distance value set of the dangerous source. and harmful gas content value set .

[0069] In this embodiment, the distance value set The distance values ​​are expressed as ,in, , , , They are No. 1, 2, , n distance values ​​from the hazard source; set of harmful gas content values The gas content values ​​are expressed as ,in, , , , They are No. 1, 2, , n gas content values.

[0070] For the distance value set and harmful gas content value set Explanation: If in this embodiment, the first detection radius r = 5, the second detection radius R = 10, the distance difference =5, and the distance difference interval b=1, then =5, assuming the warning gas content threshold .but The values ​​in are ,and is the gas content value, assuming , which is consistent with the theory that the gas content value decreases with the distance.

[0071] Step S4-3: Based on the distance value set of the danger source and harmful gas content value set , calculate the hazardous content value of the hazardous source: ;in, is the hazardous content value of the hazardous source, A set of harmful gas content values The average value of harmful gas content in is a distance value set The number of distance values ​​in , is a distance value set The distance values, A set of harmful gas content values The The harmful gas content value, is a distance value set The average value of the distance in the hazard source; and the hazardous sources are divided into different hazard levels according to the hazardous content values ​​of the hazardous sources.

[0072] It should be noted that the least squares method is a mathematical optimization technique that finds the best function match for data by minimizing the sum of squares of errors. It is often used in problems such as curve fitting. For the fitted straight line y = ax + b, the least squares method is to determine the values ​​of parameters a and b so that the sum of squares of errors between the actual data points and the fitted straight line is minimized. The present invention uses the least squares method calculation formula after deformation for this step to obtain a model that is closest to the actual data trend, that is, the hazardous content value of the hazardous source is equal to b in the fitting line. When the distance is zero, the gas content of the dangerous source is determined, and the danger level of the dangerous source is further determined according to the gas content of the dangerous source when the distance is zero. In When the hazardous source is judged to be the first hazardous level; if the hazardous content value of the hazardous source is In When the hazardous source is judged to be the second hazardous level; if the hazardous content value of the hazardous source is In When the hazard source is judged to be the third hazard level; and are the first danger level threshold and the second danger level threshold, respectively. The higher the hazard level, the higher the degree of danger of the hazard source.

[0073] Step S5: According to the characteristic marking of each hazard source in the workplace and the hazard level of each hazard source, a treatment route for treating the hazard source is planned, and the characteristic marked hazard source is treated according to the treatment route.

[0074] Step S5-1: According to the hazard level of the hazard source, Divided into A level value.

[0075] In order to reduce repeated routes and time investment, the hazards in the workplace are divided into different hazard levels, starting from the lowest to the highest. Divided into The larger the value, the more harmful gases released by the hazard source, and the more dangerous the hazard source is. level.

[0076] Step S5-2: Find all the hazard sources with the largest level value. If there is a hazard source marked with the first characteristic, randomly find a hazard source p from the hazard sources marked with the first characteristic. Otherwise, if there is no hazard source marked with the first characteristic, randomly find a hazard source p from all the hazard sources with the largest level value and start processing with hazard source p.

[0077] Step S5-3: Find the hazard source with the closest characteristic mark to the hazard source p , the distance between the two is If satisfied , then the source of danger As the next hazard source to be addressed, is the level value of the hazard source p, For dangerous sources The level value of is the difference between the allowed level values ​​of the two. .

[0078] Step S5-4: If not satisfied , find the dangerous source with the characteristic mark that is p times closest to the dangerous source , the distance between the two is Indicates that if satisfied ,in is a constant, then the hazard source As the next treatment source of danger. .

[0079] Step S5-5: Otherwise, if not satisfied , the source of danger Replace the source of danger , repeat steps S5-3 to S5-5 until the next hazard source is found; if the next hazard source is not found after executing the repeated steps, the hazard source with the closest feature mark to the hazard source p is marked As the next source of hazard to be addressed;

[0080] At this point, steps S5-3 to S5-5 are repeated to obtain a treatment route for treating the hazardous source, and the hazardous source in the workplace is treated according to the treatment route.

[0081] The present invention obtains the workplace layout drawing and the hazard source layout drawing, establishes the BIM model of the workplace, and marks each hazard source in the BIM model; plans the inspection order of the hazard source in the BIM model; obtains the harmful gas content value of each hazard source, and marks each hazard source with different characteristics; and divides each hazard source in the workplace into different hazard levels; plans the treatment route for treating the hazard source, and treats the characteristic-marked hazard source according to the treatment route.
