Technical Field

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

[0002] The chemical transportation industrial chain involves multiple links, including the production, warehousing, transportation, distribution, and sales of chemical products, etc. Each link is interrelated and mutually influential, and efficient coordination and management are required to ensure the smooth operation of the entire industrial chain; most chemical products have characteristics such as flammable, explosive, toxic, and harmful. Once accidents such as leakage and fire occur during transportation, they will pose a serious threat to human life, the environment, and property. Therefore, chemical transportation has extremely high requirements for safety and requires strict safety management and monitoring measures. With the development of the Internet of Things technology, a large amount of data has been generated in the chemical transportation industrial chain, such as vehicle driving data, cargo status data, environmental monitoring data, etc.; when making decisions on chemical transportation in the current technology, it is impossible to automatically adjust the selection and decision-making of chemical transportation vehicles according to the characteristics of chemical products, and only models constructed based on historical data are used for management and decision-making, lacking the prediction of possible problems. Therefore, the insufficient prediction ability of possible environmental impacts leads to low transportation safety and transportation efficiency, and there will be situations where the results analyzed from historical data are different; and currently, when monitoring the situation of transportation vehicles, the method of setting fixed thresholds for anomaly detection has problems of untimely accident discovery and low accuracy in judging abnormal situations. Summary of the Invention

[0003] The purpose of the present invention is to provide a chemical transportation industrial chain management system and method to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A chemical transportation industrial chain management method, the method includes the following steps: S1. Collect the driving data of chemical transportation vehicles and the temperature information of the on-vehicle cargo, collect the accident rate and on-time delivery rate of chemical transportation vehicles of different enterprises, and collect weather information and chemical product hazard degree information in real time; S2.

Analyze and calculate the vehicle selection priority according to the analyzed chemical transportation efficiency and transportation safety evaluation indexes, and adjust the weights according to the collected weather information and chemical product hazard degree information; S4. Dispatch chemical transportation vehicles according to the analyzed vehicle selection priority and monitor the selected vehicles in real time.

[0005] Further, in step S1: collect the acceleration, driving time, and driving distance of the chemical transportation vehicle during driving through the on-vehicle device, and collect the temperature information of the on-vehicle cargo; collect the accident rate and on-time delivery rate of different chemical transportation enterprises through the enterprise's historical transportation information, and collect the danger level information of chemical products; collect the weather information in real time through the weather station; conduct preliminary processing on the collected information. First, remove irrelevant information through denoising and filtering, then compare and analyze the collected cargo temperature information to obtain the temperature fluctuation value of the on-vehicle chemical products; and analyze the danger level of chemical products based on the collected types of chemical products and the characteristics of different products; analyze the quality of the day's weather based on the collected weather information; compare and analyze the acceleration information of the chemical transportation vehicle to obtain the maximum acceleration value during driving.

[0006] Further, in step S2: through the transportation time t of the chemical transportation vehicle collected on a transportation route i and the transportation distance L i , where i represents the label of different transportation routes; and collect the vehicle utilization rate M and the on-time delivery rate J; analyze and weighted fuse the collected data to obtain the chemical transportation efficiency of the chemical vehicle; the chemical transportation efficiency is calculated by the following formula: ; where, W1 represents the chemical transportation efficiency; c1 represents the influence weight of the chemical transportation rate on the chemical transportation efficiency, c2 represents the influence weight of the on-time delivery rate on the chemical transportation efficiency, c3 represents the influence weight of the vehicle utilization rate on the chemical transportation efficiency; represents the chemical transportation rate reference value; t s represents the actual transportation time of the vehicle, t k represents the available transportation time of the vehicle, t s and the ratio of t k represents the vehicle utilization rate M; Through the analysis and fusion of the temperature fluctuation value ΔT of the on-vehicle cargo during the chemical transportation process, the maximum acceleration value a max monitored when the chemical transportation vehicle has a speed change; and the vehicle accident rate S, obtain the safety evaluation index W2 of chemical transportation; the safety evaluation index of chemical transportation is calculated by the following formula: ; where, W2 represents the safety evaluation index of chemical transportation; represents the temperature fluctuation threshold of the on-vehicle cargo; a0 represents the vehicle acceleration reference value during chemical transportation; c4 represents the influence weight of the temperature fluctuation value of the on-vehicle cargo on the safety of chemical transportation, c5 represents the influence weight of the maximum vehicle acceleration value on the safety of chemical transportation, c6 represents the influence weight of the accident rate on the safety of chemical transportation; Set up a screening mechanism for combining chemical transportation efficiency and chemical transportation safety evaluation indicators to conduct the first round of screening on chemical transportation vehicles; set a screening threshold W 1min and W 2min ,W 1min where represents the screening threshold for chemical transportation efficiency, and W 2min represents the screening threshold for chemical transportation safety evaluation indicators; compare and analyze the calculated W1 and W2 with the set screening thresholds to screen out unqualified vehicles; the comparison and analysis results are as follows: If W1>W 1min and W2>W 2min ,it is judged that the vehicle has high chemical transportation efficiency and high safety, and is rated as a vehicle of level A1, and a classification priority Q is set for the vehicle of level A1 A1 ; If W1≤W 1min and W2>W 2min ,it is judged that the vehicle has high transportation safety and is rated as a vehicle of level A2, and a classification priority Q is set for the vehicle of level A2 A2 ; If W2≤W 2min ,it is judged that the transportation safety of the vehicle is low, and such vehicles will be screened out in advance and not enter the subsequent selection range of chemical transportation vehicles.

[0007] Furthermore, in step S3: Calculate the selection priority Q of chemical transportation vehicles according to the analyzed chemical transportation efficiency and chemical transportation safety evaluation indicators. When calculating the selection priority of chemical transportation vehicles, set the weight of chemical transportation efficiency as ,and the weight of chemical transportation safety evaluation indicators as ,then calculate the vehicle selection priority Q according to the following formula: ; where, Q represents the vehicle selection priority; When calculating the selection priority of vehicles for chemical transportation, the weights and It is a dynamically changing value, which is adjusted according to the degree of danger of the chemical products collected and the quality of the weather on the day of chemical transportation. For example, if the degree of danger of the chemical products to be transported is high, 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 degree of danger of the chemical products to be transported is low, 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 quality of the weather is set as G. The higher the value of G, the better the weather conditions. and It is adjusted and changed according to the following formula: ; ; Among them, represents the reference value of the set weight ; represents the reference value of the set weight ; D0 represents the reference value of the degree of danger of chemical products; G0 represents the reference value of the quality of the weather. The reference value is defined to measure the change ratio of the weight, the degree of danger of chemical products and the quality of the weather. 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 reference value of the degree of danger, 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 ; Add the calculated vehicle selection priority Q to the hierarchical priority to obtain the final vehicle selection priority. The vehicle selection priorities of the two hierarchical vehicles are: Q A1 ′ = Q A1 + Q; Q A2 ′ = Q A2 + Q; Among them, Q A1 ′ represents the final vehicle selection priority of A1-level vehicles, Q A2' represents the final vehicle selection priority of Class A2 vehicles; the calculated final vehicle selection priority is used for vehicle sorting; the method of calculating the vehicle selection priority using a weight coefficient that can be dynamically adjusted according to the actual situation can ensure the safety during chemical transportation to the greatest extent and improve the transportation efficiency on the basis of ensuring safety.

[0008] Further, in step S4: Generate a chemical transportation vehicle scheduling plan suggestion based on the calculated final vehicle selection priority; Provide suggestions for chemical transportation vehicle selection to users according to the calculation results of the final vehicle selection priority, arrange different chemical transportation vehicles in descending order according to the final vehicle selection priority, and visually display the arrangement order and analysis results to users, and give prompts to users on the visual interface, suggesting that users choose chemical transportation vehicles with a high vehicle selection priority; After selecting the chemical transportation vehicle, set the dynamic change value of the vehicle operation data monitoring threshold according to the weather quality and the danger degree of the chemical product, and monitor the vehicle operation status in real time; Set the vehicle acceleration threshold and the threshold of the change in the temperature of the on-vehicle cargo ΔT′, which are used to monitor and control the status of chemical transportation vehicles in real time; The set monitoring threshold is adjusted according to the weather conditions of the day and the danger degree of the chemical product, and the adjustment method of the monitoring threshold is: ; ; where represents the standard value of the acceleration monitoring threshold set by the system; represents the unit acceleration adjustment amount; represents the standard value of the threshold of the change in the temperature of the on-vehicle cargo set by the system; represents the proportional coefficient of the influence of acceleration change on the temperature of the on-vehicle cargo; Using the weight coefficient to adjust the vehicle acceleration threshold can achieve the effect of adjusting the acceleration threshold according to the weather conditions and the danger degree of the chemical product, and the vehicle acceleration change value can affect the change in the temperature of the on-vehicle cargo, so the change in the acceleration threshold is used to limit and adjust the on-vehicle cargo threshold to prevent redundant alarm situations during the monitoring process of the change value of the on-vehicle cargo temperature caused by the increase in the acceleration threshold when conditions permit; After the selected vehicle starts to carry out chemical product transportation work, monitor and collect the vehicle acceleration and the change value of the temperature of the on-vehicle cargo ΔT in real time, and compare the collected values with the monitoring threshold for comparative analysis, and issue a warning according to the analysis result: If ≤ and ΔT ≤ ΔT′, it is judged that the vehicle is in normal condition; If > And when ΔT ≤ ΔT′, if it is determined that the vehicle acceleration is high, a warning is issued and a voice prompt is given to the driver to control the vehicle acceleration until the vehicle acceleration returns to a state lower than the monitoring threshold, and then the warning and voice prompt are cancelled; If ΔT > ΔT′ and ≤ , if it is determined that the temperature of the on-vehicle cargo fluctuates abnormally, a warning is issued to prompt the driver of the abnormal situation, and an instruction is issued to control the temperature control equipment of the on-vehicle tank to strengthen temperature control; and the temperature change of the on-vehicle cargo is further monitored. If the temperature change value of the on-vehicle cargo does not return to normal within the time Δt, an alarm is issued and a voice prompt is given to the driver to transfer the vehicle to a safe area for isolation and inspection of the on-vehicle cargo; if the temperature change value of the on-vehicle cargo returns to normal within the time Δt, the warning is cancelled; If > and ΔT > ΔT′, if it is determined that the vehicle acceleration is high and the temperature of the on-vehicle cargo fluctuates abnormally, a warning is issued and a voice prompt is given to the driver to control the vehicle acceleration. At the same time, an instruction is issued to control the temperature control equipment of the on-vehicle tank to strengthen temperature control; until the vehicle acceleration returns to a state lower than the monitoring threshold, the voice prompt for controlling the vehicle acceleration is stopped; while prompting the driver to control the vehicle acceleration, the temperature fluctuation of the on-vehicle cargo is monitored. If the temperature change value of the on-vehicle cargo does not return to normal within the time Δt, an alarm is issued and a voice prompt is given to the driver to transfer the vehicle to a safe area for isolation and waiting for inspection of the on-vehicle cargo; if the temperature change value of the on-vehicle cargo returns to normal within the time Δt, the warning is cancelled; After detecting an abnormal situation, the abnormal situation is recorded. If it is detected that the vehicle acceleration is abnormal n1 times, a voice prompt is issued to the driver to remind the driver to take a rest to avoid fatigue driving; if it is detected that the temperature fluctuation of the on-vehicle cargo is abnormal n2 times, a voice prompt is issued to the driver to instruct the driver to stop chemical transportation and park the vehicle in a safe area for isolation and wait for further inspection; the driving situation of the vehicle is monitored in real time and a reminder is given when an abnormal situation occurs.
