Description

Technical Field

[0001] The present invention relates to the technical field of chemical transportation management, and in particular to a chemical transportation industry chain management system and method. Background Art

[0002] The chemical transportation industry chain involves multiple links, including the production, warehousing, transportation, distribution, and sales of chemical products. These links are interconnected and mutually influential, requiring efficient coordination and management to ensure the smooth operation of the entire industry chain. Chemical products are often flammable, explosive, toxic, and hazardous. Leaks, fires, and other accidents during transportation pose serious threats to life, the environment, and property. Therefore, chemical transportation places extremely high demands on safety, requiring strict safety management and monitoring measures. With the development of the Internet of Things (IoT), the chemical transportation industry chain is generating a vast amount of data, such as vehicle driving data, cargo status data, and environmental monitoring data. Current technologies for chemical transportation decisions are unable to automatically adjust the selection and decision-making of chemical transportation vehicles based on the characteristics of chemical products. Instead, management and decision-making rely solely on models constructed from historical data, lacking the ability to predict potential problems. Consequently, this inability to predict potential environmental impacts leads to reduced transportation safety and efficiency, and can result in discrepancies in the results analyzed based on historical data. Furthermore, current methods for monitoring transportation vehicle performance, using fixed thresholds for anomaly detection, suffer from delays in accident detection and low accuracy in abnormal situation assessment. Summary of the Invention

[0009] Furthermore, in step S1: the acceleration, driving time and driving distance of the chemical transport vehicle during driving are collected through the on-board equipment, and the temperature information of the cargo on the vehicle is collected; the accident rate and on-time delivery rate of different chemical transport companies are collected through the company's historical transportation information, and the dangerousness information of chemical products is collected; weather information is collected in real time through the meteorological station; the collected information is preliminarily processed, first removing irrelevant information through denoising and filtering, and then comparing and analyzing the collected cargo temperature information to obtain the temperature fluctuation value of the on-board chemical products; and the dangerousness of the chemical products is analyzed according to the types of chemical products collected and the characteristics of different products; the good or bad weather of the day is analyzed according to the collected weather information; the collected acceleration information of the chemical transport vehicles is compared and analyzed to obtain the maximum acceleration during driving.

[0010] Further, in step S2: by collecting the transportation time t of the chemical transportation vehicle on a transportation route i and transport distance L i , where i represents the number of different transportation routes; and collect vehicle utilization rate M and on-time delivery rate J; analyze and weightedly integrate the collected data to obtain the chemical transportation efficiency of chemical vehicles; chemical transportation efficiency is calculated using the following formula:

[0011] ;

[0012] Among them, W1 represents chemical transportation efficiency; c1 represents the influence weight of chemical transportation rate on chemical transportation efficiency; c2 represents the influence weight of on-time delivery rate on chemical transportation efficiency; c3 represents the influence weight of vehicle utilization rate on chemical transportation efficiency; Indicates the chemical transportation rate benchmark value; t s Indicates the actual transportation time of the vehicle, t k represents the available transportation time of the vehicle, t s With t k The ratio represents the vehicle utilization rate M;

[0013] By collecting the temperature fluctuation value ΔT of the cargo on board during chemical transportation, the maximum acceleration a of the chemical transportation vehicle is monitored when the speed changes. max The vehicle accident rate S is analyzed and integrated to obtain the safety assessment index W2 of chemical transportation; the chemical transportation safety assessment index is calculated using the following formula:

[0015] Among them, W2 represents the chemical transportation safety assessment index; represents the temperature fluctuation threshold of the cargo on board; a0 represents the vehicle acceleration baseline value during chemical transportation; c4 represents the impact weight of the cargo temperature fluctuation value on chemical transportation safety; c5 represents the impact weight of the maximum vehicle acceleration on chemical transportation safety; and c6 represents the impact weight of the accident rate on chemical transportation safety.

[0016] Set up a screening mechanism that combines chemical transportation efficiency and chemical transportation safety assessment indicators to perform the first level of screening for chemical transportation vehicles; set the screening threshold W 1min and W 2min , W 1min Where W represents the chemical transport efficiency screening threshold, 2min Indicates the screening threshold of chemical transportation safety assessment indicators; the calculated W1 and W2 are compared and analyzed with the set screening threshold to screen out unqualified vehicles; the comparative analysis results are as follows:

[0017] If W1>W 1min And W2>W 2min , judge that the vehicle has high chemical transportation efficiency and high safety, and rate it as A1 vehicle, and set a hierarchical priority Q for A1 vehicles A1 ;

[0018] If W1≤W 1min And W2>W 2min , judge that the vehicle has high transport safety and is rated as A2 vehicle. A hierarchical priority Q is set for A2 vehicles. A2 ;

[0019] If W2≤W 2min If the transportation safety of a vehicle is judged to be low, such vehicle will be screened out in advance and will not be included in the subsequent chemical transportation vehicle selection range.

For example, if the chemical products to be transported are highly dangerous, such as flammable, explosive or toxic substances, or the weather conditions are poor, such as rain, fog and snow, etc., then the weight of the chemical transportation safety assessment index in the calculation of vehicle selection priority should be increased. If the chemical products to be transported are less dangerous, such as flammable or slightly toxic but not explosive products, or the weather conditions are good, such as sunny or cloudy days, then the weight of transportation efficiency can be slightly increased to improve transportation efficiency on the basis of safety. The degree of danger D of the chemical products is obtained from the chemical product information provided by the chemical product supplier. The higher the value of D, the higher the degree of danger of the chemical products. According to the meteorological satellite, the weather conditions on the day of chemical transportation are collected in real time, and the weather quality is set as G.

The reference value is defined to measure the change ratio of weight, the degree of danger of chemical products and the weather quality. For example, according to the properties of chemical products, such as whether they are flammable or explosive, the degree of danger of chemical products is divided into {G1, G2, G3, G4, G5}, where G1 < G2 < G3 < G4 < G5. The average value of the five chemical product danger degree values is positioned as the danger degree reference value, denoted as G0, which is used to measure the degree of danger of chemical products; p1 represents the influence weight of G on , p2 represents the influence weight of D on ; p3 represents the influence weight of G on , p4 represents the influence weight of D on ;
