Description

Technical Field

[0001] The present application relates to the field of hazardous chemicals storage safety, and more specifically, to a logistics warehousing operation management method and system for hazardous chemicals storage safety. Background Art

[0002] Hazardous chemicals, or dangerous chemicals, are an indispensable part of modern industry, agriculture, medical care and other fields. From fertilizers and pesticides to fuels, medicines, and various industrial raw materials and chemicals, they play a vital role in social and economic development and daily life. However, due to the inherent dangers of these chemicals, such as flammable, explosive, toxic, and harmful properties, their transportation process becomes extremely complicated and dangerous. Therefore, the logistics and transportation of hazardous chemicals has become a key link in ensuring that these chemicals are safely and efficiently transported from the production site to the consumption site. However, at the same time, the logistics and transportation of hazardous chemicals also faces many challenges. These include the selection of transportation routes, the selection of transportation methods, the safety of transportation vehicles and equipment, the professional quality of transportation personnel, emergency response capabilities, etc. These issues are not only related to the safety and efficiency of hazardous chemical logistics and transportation, but also directly affect environmental protection and public safety;

[0003] In the existing technology, when transporting hazardous chemicals, it is impossible to comprehensively analyze vehicle abnormalities and hazardous chemicals abnormalities in real time during transportation. Abnormal shaking of vehicles due to uneven roads often occurs, which leads to abnormal transportation of hazardous chemicals. The existing technology cannot accurately estimate the abnormal transportation of hazardous chemicals caused by abnormal road flatness and vehicle abnormalities, resulting in low safety of hazardous chemicals logistics transportation. Most of the existing technologies have the above problems.

[0004] For example, a Chinese patent with application publication number CN106096885A discloses a hazardous chemical logistics supervision method and supervision system based on Internet of Things technology, including a safety monitoring device, a signal analysis and alarm device, a monitoring center, and auxiliary devices such as a 3G / 4G wireless communication module, a safety supervision code carrier, and a supervision code reader. When hazardous chemicals leave the factory, product information is registered through the logistics management system and uploaded to the monitoring center for coding, and the product information is bound to the transportation information; during the transportation of hazardous chemicals, the status of transportation tools, containers, etc. is collected and analyzed through safety control devices and signal analysis and alarm devices, and the data is transmitted to the monitoring center to complete the full monitoring of the logistics process. This invention integrates sensing technology, satellite positioning technology, wireless network communication technology, GIS geographic information technology and database technology. By utilizing sensor networks and combining GPS and GIS technology, dynamic supervision of transportation tools and hazardous chemical transportation is achieved;

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0049] Example 1

[0050] In order to solve the technical problems raised in the background technology, the present application provides a preferred embodiment: Figure 5 As shown, this embodiment acquires road data through a road data acquisition terminal, acquires vehicle data through a vehicle shaking sensor, collects hazardous chemicals data during transportation through a hazardous chemicals transportation sensor, and transmits the data to a logistics vehicle terminal and a logistics management terminal after processing. The specific contents are as follows: Figure 1-Figure 3 As shown, the logistics warehousing operation management method for the safe storage of hazardous chemicals includes the following specific steps:

[0051] S1. Obtain carriage transportation data, road data and hazardous chemicals storage data during hazardous chemicals logistics transportation;

[0052] In this embodiment, the specific content of S1 is:

[0053] S11. Collecting road smoothness data through a road data acquisition terminal, wherein the road smoothness data includes road surface convexity data and road surface concave data, and storing them in a first storage component. It should be noted that the road surface convexity data here includes the area, maximum height and position data of the road surface convexity, and the road surface concave data includes the area, maximum depth and position data of the road surface concave. It should be particularly noted that the road smoothness data here is obtained through drone aerial photography of the traffic management department or through the road information release page of the traffic management department, and is used to evaluate the road smoothness, and then comprehensively consider the road hazard situation during the storage and transportation of hazardous chemicals;

[0054] It should be noted here that the specific steps for obtaining road leveling data through drone aerial photography are as follows:

[0055] S111. Flight preparation: First, select the appropriate drone model and aerial photography equipment according to the characteristics and scope of the target road;

[0056] S112. Route planning: Before flying, the drone’s route needs to be planned;

[0057] S113, Flight execution: Control the drone to take aerial photos according to the planned route;

[0058] S114, data acquisition: after the drone completes the aerial photography, the aerial photography data is imported into the corresponding processing software, which can analyze and process the aerial photography data to extract the elevation information, texture information, etc. of the road surface;

[0059] S115, data processing: process and analyze the acquired road leveling data. Professional data processing software, such as ArcGIS, Photoshop, etc., can be used to process the elevation information and generate a three-dimensional model or elevation map of the road surface;

[0060] S12, obtaining the shaking frequency and shaking amplitude data of the transport carriage during driving through the vehicle shaking sensor, and storing the data in the second storage component;

[0061] The internal temperature and pressure data during the storage of hazardous chemicals are important parameters for assessing the degree of danger of hazardous chemicals. These data can reflect the physical and chemical state of hazardous chemicals, as well as potential safety risks. First of all, the internal temperature is one of the key parameters in the storage process of hazardous chemicals. The increase in temperature will increase the volume and pressure of hazardous chemicals. This is due to the physical phenomenon of thermal expansion and contraction. For flammable liquids, the increase in temperature will lead to faster evaporation rate, increased vapor concentration on the liquid surface, and increased possibility of forming an explosive mixture with air, thereby increasing the risk of fire and explosion. In addition, some hazardous chemicals are easily decomposed after being heated, releasing oxygen or even oxygen atoms, promoting the oxidation of other substances, and releasing a lot of heat. If the heat accumulates and is not dissipated, it may cause the temperature to rise, accelerate the oxidation rate, generate more heat, and eventually cause spontaneous combustion or explosion; secondly, pressure is also an important indicator for assessing the degree of danger of hazardous chemicals. For gases, their expansion coefficient is larger. As the temperature rises, the pressure in the cylinder will increase, which may cause explosion. In addition, some hazardous chemicals will produce gas after being heated, causing the internal pressure of the container to increase. If the pressure exceeds the limit that the container can withstand, it may cause the container to malfunction or burst. By monitoring the internal temperature and pressure data of hazardous chemicals during storage, potential safety hazards and risks can be discovered in time. These data can provide important information about the status of hazardous chemicals and help predict possible accident risks.

[0062] S13, obtaining the internal temperature and pressure data of the hazardous chemicals through the hazardous chemicals transportation sensor, and storing the data in the third storage component;

[0063] Since the hazardous chemicals transport sensor here is installed in the carriage, the vibration of the carriage may cause vibration errors in the hazardous chemicals transport sensor, so it is necessary to select an anti-interference hazardous chemicals transport sensor;

[0064] S2, importing the acquired historical carriage transportation data and road data into the carriage anomaly assessment strategy to perform carriage anomaly assessment;

[0065] In this embodiment, S2 includes the following specific steps:

[0066] S21, dividing the travel road into several sections according to a set interval, where it should be noted that the set interval here is preferably 1 km, obtaining road surface convexity data and road surface concave data of the travel on the previous section of the road, and simultaneously obtaining the shaking frequency and shaking amplitude data of the transport carriage during the travel on the previous section of the road;

[0067] S22, importing the acquired road surface convex data and road surface concave data of the previous section of the road into a road abnormal value calculation formula to calculate the road abnormal value of the previous section of the road, wherein the road abnormal value calculation formula is: Wherein, H is the length of the road segment, m is the number of surface protrusions of the road segment, n is the number of surface depressions of the road segment, si is the area of ​​the ith protrusion of the road segment, hi is the height of the ith protrusion of the road segment, rz is the average distance between defects of the road segment, wherein defects include protrusions and depressions, s is the set safety value of the protrusion area, h is the set safety value of the protrusion height, Sj is the area of ​​the jth depression of the road segment, Hj is the depth of the jth depression of the road segment, Sp is the set safety value of the depression area, and Hp is the set safety value of the depression depth. In this way, the flatness of the road surface is comprehensively analyzed through the protrusions and depressions of the road surface;

[0068] By observing and analyzing the bumps and depressions on the road surface, a comprehensive assessment of the road surface flatness can be made. First, the bumps and depressions on the road surface are a direct reflection of the road surface flatness. Bumps may be caused by uneven settlement of the roadbed, soil expansion, construction quality problems, etc., while depressions may be caused by factors such as wear of road materials, long-term effects of vehicle loads, and rainwater erosion. The existence of these bumps and depressions will destroy the continuity and flatness of the road surface and affect the driving quality of vehicles. Secondly, the degree and distribution of bumps and depressions on the road surface are also important bases for assessing the flatness of the road surface. If the degree of bumps and depressions is small and evenly distributed, it means that the overall flatness of the road surface is good; if the degree of bumps and depressions is large and unevenly distributed, it means that the flatness of the road surface is poor. In addition, the distribution of bumps and depressions can also reflect the use and maintenance of the road surface.

[0069] By observing and analyzing the bumps and depressions on the road surface, a comprehensive assessment of the road surface flatness can be made;

[0070] S23, importing the acquired transport carriage shaking frequency and shaking amplitude data during the driving process of the previous section of the road into the carriage transportation abnormal value calculation formula to calculate the carriage transportation abnormal value of the previous section of the road, wherein the carriage operation abnormal value calculation formula is: Where T is the travel time of the previous road, Dt is the sway amplitude of the transport carriage at time t, D is the safe swing amplitude of the transport carriage, and dt is the time integral;

[0071] S3, importing the obtained carriage abnormality assessment results and hazardous chemicals storage data into the transportation process abnormality analysis model to perform transportation process abnormality analysis;

[0072] In this embodiment, S3 includes the following specific steps:

[0073] S31, obtaining the hazardous chemical storage data during the driving process of the previous section of the road, importing the hazardous chemical storage data at the start time of the previous section of the road into the hazardous chemical storage abnormal value calculation formula to calculate the hazardous chemical storage abnormal value at the start time, and importing the hazardous chemical storage data at the end time of the previous section of the road into the hazardous chemical storage abnormal value calculation formula to calculate the hazardous chemical storage abnormal value at the end time, wherein the hazardous chemical storage abnormal value calculation formula is: Wherein, c is the temperature ratio coefficient, Rz is the hazardous chemical temperature at the corresponding moment, Rm is the median value of the hazardous chemical storage temperature safety range, Rmax is the maximum value of the hazardous chemical storage temperature safety range, Rmin is the minimum value of the storage temperature safety range, Yz is the hazardous chemical pressure at the corresponding moment, Ym is the median value of the hazardous chemical storage pressure safety range, Ymax is the maximum value of the hazardous chemical storage pressure safety range, and Ymin is the minimum value of the hazardous chemical storage pressure safety range;

[0075] S4, obtaining the road conditions of the next stage and the abnormal analysis results of the transportation process and importing them into the transportation hazard prediction strategy to perform transportation hazard prediction;

[0076] In this embodiment, obtaining the road conditions of the next stage and the abnormal analysis results of the transportation process and importing them into the transportation risk prediction strategy for transportation risk prediction includes the following specific contents:

[0077] S41, obtaining the collected road leveling data of the lower section of the road, and importing the data into a road abnormality value calculation formula to calculate the road abnormality value of the lower section of the road;

[0078] S42, obtaining the road abnormality value of the next section of the road, the road abnormality value of the previous section of the road and the abnormal value of the transportation process, and substituting them into the calculation formula of the abnormality estimation value of the next section of the transportation process to calculate the abnormality estimation value of the next section of the transportation process, wherein the calculation formula of the abnormality estimation value of the next section of the transportation process is: Among them, Pyc is the transportation process abnormal value of the previous road, exp() is the power of the natural constant e, Pdm is the road abnormal value of the next road, and Pdz is the road abnormal value of the previous road;

[0079] S5. Provide early warning of logistics and transportation risks based on the obtained transportation risk prediction results;

[0080] In this embodiment, the logistics transportation risk warning according to the obtained transportation risk prediction result includes the following specific contents:

[0081] The calculated estimated abnormality value of the next transportation process is compared with the set abnormality threshold of the transportation process. If the estimated abnormality value of the next transportation process is greater than or equal to the set abnormality threshold of the transportation process, a road hazard warning will be issued to the management end and the logistics vehicle, and the logistics vehicle needs to be reminded to change to a safe path. If the estimated abnormality value of the next transportation process is less than the set abnormality threshold of the transportation process, no road hazard warning will be issued to the management end and the logistics vehicle.

[0082] It should be noted here that the value-taking method of the transportation process abnormality threshold, storage change speed abnormal value ratio coefficient, temperature ratio coefficient and temperature ratio coefficient in this embodiment is: obtain 500 sets of carriage transportation data, road data and hazardous chemicals storage situation data in the hazardous chemicals logistics transportation process, substitute them into the calculation formula for the abnormal estimated value of the next transportation process to calculate the abnormal estimated value of the next transportation process, and at the same time extract the judgment results of whether these hazardous chemicals logistics transportation processes will be dangerous in the next transportation process, import the abnormal estimated value of the next transportation process and the judgment results of whether danger will occur in the next transportation process into the fitting software, and output the values ​​of the transportation process abnormality threshold, storage change speed abnormal value ratio coefficient, temperature ratio coefficient and temperature ratio coefficient that meet the maximum judgment accuracy.
