Description

Technical Field

[0001] This invention relates to the field of concrete production management technology, specifically to a digital management method and system for concrete production. Background Technology

[0002] Digital management of concrete production involves the introduction of technologies such as the Internet of Things and big data to collect and analyze data from all aspects of production, including raw material management, production control, and distribution management, thereby achieving intelligent control. In particular, distribution management improves vehicle transportation efficiency through route planning by integrating various road condition data.

[0003] For example, Chinese patent document CN120047065A discloses a concrete transportation monitoring method and system, including the following steps: Step S1: Data acquisition, acquiring concrete status data and environmental data in real time through a data acquisition module, which includes a temperature sensor, humidity sensor, vibration sensor, light sensor, and high-definition camera device; Step S2: Data fusion and preprocessing; Step S3: Data transmission and cloud storage; Step S4: Cloud data analysis; Step S5: Anomaly detection and early warning response. By using multiple sensors and a high-definition camera device in the data acquisition module, concrete status data and environmental data are acquired in real time, achieving multi-dimensional information monitoring. The edge computing module performs data preprocessing, significantly reducing data transmission latency, improving system real-time performance, and achieving blind-spot-free monitoring of the entire concrete transportation process, ensuring accurate and reliable data.

[0004] For example, Chinese patent document CN119904074A discloses a vehicle queuing method and system for concrete transportation. This invention, through automated scheduling and task allocation, automatically generates an initial scheduling list based on the construction site's demand and progress, assigning a unique task number to each vehicle to ensure clear and orderly tasks for each vehicle. Real-time information transmission enables the system to send detailed loading times and locations, as well as estimated arrival times, to drivers via onboard equipment, reducing waiting time and improving response efficiency. Dynamic route planning plans the optimal route for each vehicle based on current traffic conditions, ensuring vehicles arrive at the construction site on time. Furthermore, as vehicles approach the construction site, the system automatically sends the estimated arrival time and specific parking location to the site management team, coordinating vehicles to park and unload in a predetermined order, improving the operational efficiency of the construction site.

[0005] The above solution also has the following shortcomings: 1. Concrete may lose strength during transportation due to road conditions and environmental factors. Therefore, route planning aimed at ensuring strength can guarantee the quality of concrete. However, the above scheme only plans the route based on time, ignoring the impact of road conditions and environmental factors on concrete performance. This cannot guarantee the stability and controllability of concrete during transportation, thus reducing the quality of concrete.

[0006] 2. Implementing appropriate protective measures based on the state of the concrete during transportation can ensure the stability of the concrete strength. However, the above scheme only monitors the state of the concrete during transportation and lacks the setting and implementation of protective measures. This makes it impossible to translate the monitoring data into quality intervention, resulting in continuous performance deterioration. At the same time, it has no ability to respond to abnormal fluctuations and cannot cope with sudden changes in state, increasing the risk of quality loss of control, thereby causing resource waste and increased transportation costs. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a digital management method and system for concrete production.

[0008] This invention is achieved through the following technical solution: A digital management method for concrete production includes the following steps: S1. Obtain historical concrete production and transportation records, and construct a mapping table between transportation parameters and concrete strength, as well as a mapping table between concrete strength and protective measures. S2. Obtain the order data of the concrete that has been produced. According to the mapping relationship table between transportation parameters and concrete strength, select the best transportation route for the concrete. At the same time, obtain the transportation parameters of the best transportation route for the concrete. And use the mapping relationship table between concrete strength and protection measures to set the set of protection measures for the concrete. S3. During concrete transportation, monitor the condition of the concrete and provide feedback.

[0009] The specific process of step S1 is as follows: S11. Obtain the pre-transport concrete strength, post-transport concrete strength, and transportation parameters corresponding to each concrete transport from historical concrete production and transportation records. Analyze and construct a mapping relationship table between transportation parameters and concrete strength using the pre-transport concrete strength, post-transport concrete strength, and transportation parameters corresponding to each concrete transport. S12. Using the mapping relationship table between transportation parameters and concrete strength, conduct simulation tests on concrete transportation protection, collect simulation test data, analyze and construct a mapping relationship table between concrete strength and protection measures.

[0010] The analysis and construction process of the mapping relationship table between transportation parameters and concrete strength is as follows: S111. Based on the pre-transport concrete strength corresponding to each concrete transport, the concrete quality corresponding to each concrete transport is classified to obtain the concrete grade corresponding to each concrete transport. Then, the concrete transport parameters of each concrete transport with the same concrete grade are integrated, and the pre-transport concrete strength and post-transport concrete strength corresponding to each concrete grade using each transport parameter are statistically analyzed. S112. Using the pre-transport concrete strength and post-transport concrete strength corresponding to each concrete grade and each transportation parameter, calculate the concrete strength reduction value corresponding to each concrete grade and each transportation parameter. Construct a mapping relationship table between transportation parameters and concrete strength based on the concrete strength reduction value corresponding to each concrete grade and each transportation parameter.

[0011] The analysis and construction process of the mapping relationship table between concrete strength and protection measures is as follows: S121. Based on the mapping relationship table between transportation parameters and concrete strength, design three-dimensional models of each simulated transportation route and transportation vehicle, and simulate the transportation vehicles carrying concrete of each grade on each simulated transportation route. S122. The transport vehicle is equipped with a data acquisition device to collect the state data of the concrete inside the vehicle in real time. Based on the state data of the concrete, a set of preset protection measures are executed. After the execution is completed, the state data of the concrete inside the vehicle is collected again. When the end of the route is reached, the strength of the transported concrete is tested. S123. When each concrete grade is simulated to travel on each simulated transportation route, the state data of the concrete inside the vehicle before and after each protective measure is implemented, and the concrete strength after transportation are used as simulation test data. Analyze the set of effective protective measures for each concrete grade under each state data when using each transportation parameter, and sort the set of effective protective measures. The mapping relationship table between concrete strength and protective measures is constructed by the set of effective protective measures for each concrete grade under each state data when using each transportation parameter and the sorting of the set of effective protective measures.

[0012] The specific process of step S2 is as follows: S21. Obtain the transportation destination location and preset concrete strength benchmark value from the completed concrete order data. Obtain the initial concrete strength and initial concrete grade from the production center. Based on the map system, obtain each transportation route to the transportation destination location and obtain the transportation parameters of each transportation route from the map system. Based on the mapping relationship table between transportation parameters and concrete strength, select the best transportation route for concrete from each transportation route. S22. Based on the transportation parameters of the optimal transportation route, predict the state data of concrete in the optimal transportation route, and then select the set of concrete protection measures according to the mapping relationship table between concrete strength and protection measures.

[0013] The process of selecting the optimal concrete transport route from various transport routes is as follows: S211. Based on the initial concrete strength and the preset concrete strength benchmark value, obtain the maximum allowable decrease in concrete strength. Extract the concrete strength decrease value of each transportation parameter for the initial concrete grade from the mapping relationship table between transportation parameters and concrete strength. Select each transportation parameter whose concrete strength decrease value is less than the maximum allowable decrease in concrete strength as each optional transportation parameter. S212. Calculate the similarity between the transportation parameters of each transportation route and each optional transportation parameter. When there is at least one transportation route whose transportation parameters are more than or equal to at least one optional transportation parameter, select the transportation route with the highest similarity as the best transportation route for concrete. S213. When there is no similarity greater than or equal to the similarity threshold, the risk of each transportation route is assessed, and the transportation route with the lowest risk is selected as the best transportation route for concrete.

[0014] The specific process for assessing the risks of each transportation route is as follows: The transportation parameters of each transportation route are divided into transportation data. Each transportation data in each transportation route is compared with each transportation data in each optional transportation parameter. The optional transportation parameter with the smallest difference in transportation data is selected as the target optional transportation parameter for each transportation data in each transportation route. The initial concrete grade in the mapping relationship table between transportation parameters and concrete strength is used as the concrete strength reduction value of the target optional transportation parameter as the concrete strength reduction value of each transportation data in each transportation route. The predicted concrete strength reduction value of each transportation route is calculated. Obtain the difference between each transportation data point and the transportation data point with the smallest difference between the corresponding optional transportation parameters for each transportation route, and evaluate the transportation data difference rate for each transportation route; Based on the predicted concrete strength reduction value and the transportation data difference rate for each transportation route, the risk coefficient of each transportation route is calculated, and the transportation route with the smallest risk coefficient is the transportation route with the lowest risk.

[0015] The specific process for selecting the set of concrete protection measures is as follows: S221. When the optimal transportation route selection method is S212: Obtain the set of effective protection measures under each state data when the initial grade of concrete is used with the transportation parameters that are most similar to the transportation parameters of the optimal transportation route from the mapping relationship table between concrete strength and protection measures. Use this as the set of effective protection measures under each state data. Also, extract the concrete strength reduction value when the initial grade of concrete is used with the transportation parameters that are most similar to the transportation parameters of the optimal transportation route from the mapping relationship table between transportation parameters and concrete strength. Use this as the concrete strength reduction value of the optimal transportation route. S222. Based on simulation test data, extract the state data of the concrete in the vehicle before each protection measure is implemented when the initial grade of concrete is used with the transportation parameters that are most similar to the optimal transportation route transportation parameters. Use this data as the state data of the concrete in the vehicle before each protection measure is implemented for the optimal transportation route reference. S223. Select the set of effective protection measures for the optimal transportation route from the set of effective protection measures for each state data as the set of target protection measures. Based on the concrete strength reduction value of the optimal transportation route, set the sequence interval of the optimal transportation route protection measure set. Select the union of the target protection measure sets within the corresponding sequence interval from the set of target protection measures as the set of concrete protection measures. S224. When the optimal transportation route selection method is S213, the predicted concrete strength reduction value of the optimal transportation route is used to obtain the set of effective protection measures under each state data, and steps S222 and S223 are executed to obtain the set of concrete protection measures.

[0016] The specific process of step S3 is as follows: S31. Collect concrete status data using the data acquisition device inside the transport vehicle, implement a set of concrete protection measures based on the status data, and collect real-time concrete status data again using the data acquisition device after implementation. S32. Based on the concrete state data before and after execution, analyze the concrete protection effect. When the protection effect is poor, send a signal of poor protection effect to the driver and prompt the driver to deliver the goods as soon as possible.

[0017] A system for digital management of concrete production includes: The data analysis module is used to obtain historical concrete production and transportation records, construct a mapping table between transportation parameters and concrete strength, and construct a mapping table between concrete strength and protection measures. The transportation setting module is used to obtain the order data of concrete that has been produced, select the best transportation route for concrete based on the mapping relationship table between transportation parameters and concrete strength, obtain the transportation parameters of the best transportation route for concrete, and set the set of protection measures for concrete using the mapping relationship table between concrete strength and protection measures. The monitoring and feedback module is used to monitor the condition of concrete during transportation and provide feedback.

[0018] The beneficial effects of this invention are as follows: Based on historical concrete production and transportation records, a mapping table between transportation parameters and concrete strength is constructed, and transportation simulation tests are conducted to construct a mapping table between concrete strength and protective measures. After concrete production is completed, a transportation route is selected based on the principle of qualified strength, and a corresponding set of protective measures is set. Then, the state of the concrete is monitored in real time during transportation, and corresponding feedback is provided. By analyzing the impact of transportation parameters on concrete performance, a reliable reference is provided for subsequent route selection, thereby ensuring the stability and controllability of concrete during transportation, ensuring concrete quality, and simultaneously monitoring the state of concrete during transportation and setting and implementing protective measures. This allows monitoring data to be effectively transformed into quality intervention, reducing the possibility of performance deterioration, increasing the responsiveness to abnormal fluctuations, effectively responding to sudden changes in state, reducing the risk of uncontrolled concrete quality, and thus reducing resource waste and transportation costs.

[0019] Figure 1 This is a schematic diagram of the implementation steps of the method of the present invention; Figure 2 This is a connection diagram of the system structure of the present invention. Detailed Implementation

[0020] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0021] like Figure 1 and Figure 2 As shown, the present invention provides a digital management method for concrete production, comprising the following steps: S1. Obtain historical concrete production and transportation records, and construct a mapping table between transportation parameters and concrete strength, as well as a mapping table between concrete strength and protective measures.

[0022] The specific process of step S1 is as follows: S11. Obtain the pre-transport concrete strength, post-transport concrete strength, and transportation parameters corresponding to each concrete transport from historical concrete production and transportation records. Analyze and construct a mapping relationship table between transportation parameters and concrete strength using the pre-transport concrete strength, post-transport concrete strength, and transportation parameters corresponding to each concrete transport.

[0023] The transportation parameters include road condition data and environmental data. Road condition data includes road length and damaged area, while environmental data includes ambient temperature and humidity. Historical concrete production and transportation records are retrieved from the database.

[0024] The analysis and construction process of the mapping relationship table between transportation parameters and concrete strength is as follows: S111. Based on the pre-transport concrete strength corresponding to each concrete transport, the concrete quality corresponding to each concrete transport is classified to obtain the concrete grade corresponding to each concrete transport. Then, the concrete transport parameters of each concrete transport with the same concrete grade are integrated, and the pre-transport concrete strength and post-transport concrete strength corresponding to each concrete grade using each transport parameter are statistically analyzed.

[0025] The concrete strength before each concrete transport is compared with the preset strength range corresponding to each concrete grade. If the concrete strength before each concrete transport is within the strength range corresponding to a certain concrete grade, then that concrete grade is the concrete grade corresponding to that concrete transport. The concrete grade corresponding to each concrete transport is obtained in this way.

[0026] The strength ranges corresponding to each concrete grade are set by professionals according to industry standards, and no specific numerical limits are imposed here.

[0027] S112. Using the pre-transport concrete strength and post-transport concrete strength corresponding to each concrete grade and each transportation parameter, calculate the concrete strength reduction value corresponding to each concrete grade and each transportation parameter. Construct a mapping relationship table between transportation parameters and concrete strength based on the concrete strength reduction value corresponding to each concrete grade and each transportation parameter.

[0028] The strength reduction value corresponding to each transportation parameter for each concrete grade is used to calculate the average of the difference between the concrete strength before and after transportation.

[0029] S12. Using the mapping relationship table between transportation parameters and concrete strength, conduct simulation tests on concrete transportation protection, collect simulation test data, analyze and construct a mapping relationship table between concrete strength and protection measures.

[0030] The analysis and construction process of the mapping relationship table between concrete strength and protection measures is as follows: S121. Based on the mapping relationship table between transportation parameters and concrete strength, design three-dimensional models of each simulated transportation route and transportation vehicle. Simultaneously, simulate the transportation vehicles carrying concrete of different grades on each simulated transportation route. Each simulated transportation route corresponds to one transportation parameter.

[0031] S122. The transport vehicle is equipped with a data acquisition device to collect real-time data on the state of the concrete inside the vehicle. Based on the concrete state data, a set of preset protection measures are executed. After execution, the data on the state of the concrete inside the vehicle is collected again. When the route reaches its end, the strength of the transported concrete is tested.

[0032] It should be noted that the concrete condition data includes moisture content and concrete temperature, and the data acquisition device includes a concrete moisture content meter and a temperature sensor.

[0033] Professionals pre-set several sets of protective measures based on experience and set reference values ​​for the state data to be executed for each set. When the state data matches the reference value for a particular set of protective measures, that set of protective measures can be executed. In this way, the pre-set sets of protective measures are executed based on the state data of the concrete. There are no specific numerical restrictions on the reference values ​​for the state data of each set of protective measures.

[0034] Each protective measure group includes several protective measures, which include the type and content of admixtures. The admixture types include plasticizers and retarder water-reducing agents, etc. At least one of the admixture types and contents must be different in each protective measure.

[0035] The strength of the concrete after transportation is tested using ultrasonic waves. Specifically, the strength is determined by the propagation speed and rebound value of ultrasonic waves in the concrete. The specific monitoring principle and process have been publicly disclosed and can be found on the Internet, so they will not be repeated here.

[0036] S123. When each concrete grade is simulated to travel on each simulated transportation route, the state data of the concrete inside the vehicle before and after each protective measure is implemented, and the concrete strength after transportation are used as simulation test data. Analyze the set of effective protective measures for each concrete grade under each state data when using each transportation parameter, and sort the set of effective protective measures. The mapping relationship table between concrete strength and protective measures is constructed by the set of effective protective measures for each concrete grade under each state data when using each transportation parameter and the sorting of the set of effective protective measures.

[0037] The specific process of step S123 is as follows: Calculate the standard deviation of the state data of the concrete in the vehicle before and after the implementation of each protection measure during the simulated driving of each concrete grade on each simulated transportation route. Use this deviation as the fluctuation rate of the state data before and after the implementation of each protection measure during the simulated driving of each concrete grade on each simulated transportation route. Then, calculate the difference to obtain the mitigation value of the fluctuation rate of the state data of each protection measure during the simulated driving of each concrete grade on each simulated transportation route. Calculate the concrete strength reduction value of each concrete grade during the simulated driving of each simulated transportation route according to the calculation method of the concrete strength reduction value corresponding to each transportation parameter for each concrete grade. At the same time, based on the transportation parameters of each simulated transportation route, obtain the concrete strength reduction value of each concrete grade during the simulated driving of each simulated transportation route from the mapping relationship table between transportation parameters and concrete strength. Subtract the concrete strength reduction value of each protection measure from the concrete strength reduction value of each concrete grade during the simulated driving of each simulated transportation route to obtain the concrete strength protection value of each concrete grade during the simulated driving of each simulated transportation route.

[0038] It should be noted that the calculation method for standard deviation has been publicly disclosed and can be found on the Internet, so it will not be repeated here.

[0039] The fluctuation rate mitigation value and concrete strength protection value of each protection measure execution status data of each concrete grade during simulated driving on each simulated transportation route are normalized and then the mean value is calculated to obtain the effective value of each protection measure execution of each concrete grade during simulated driving on each simulated transportation route. The set of protection measures with effective values ​​greater than the preset effective value threshold is taken as the effective protection measure set, and the descending order of the effective values ​​is taken as the order of the effective protection measure sets.

[0040] It should be noted that the effective value threshold is a benchmark value for judging whether the set of protective measures is effective. It is set and adjusted by professionals based on experience and transportation needs, and no specific numerical limit is set here.

[0041] S2. Obtain the order data of the concrete that has been produced. Based on the mapping relationship table between transportation parameters and concrete strength, select the best transportation route for the concrete. At the same time, obtain the transportation parameters of the best transportation route for the concrete. And use the mapping relationship table between concrete strength and protection measures to set the set of protection measures for the concrete.

[0042] The specific process of step S2 is as follows: S21. Obtain the transportation destination location and preset concrete strength benchmark value from the completed concrete order data. Obtain the initial concrete strength and initial concrete grade from the production center. Based on the map system, obtain each transportation route to the transportation destination location and obtain the transportation parameters of each transportation route from the map system. Based on the mapping relationship table between transportation parameters and concrete strength, select the best transportation route for concrete from each transportation route.

[0043] The process of selecting the optimal concrete transport route from various transport routes is as follows: S211. Based on the initial concrete strength and the preset concrete strength benchmark value, obtain the maximum allowable decrease in concrete strength. Extract the concrete strength decrease value of each transportation parameter for the initial concrete grade from the mapping relationship table between transportation parameters and concrete strength. Select each transportation parameter whose concrete strength decrease value is less than the maximum allowable decrease in concrete strength as each optional transportation parameter.

[0044] S212. Calculate the similarity between the transportation parameters of each transportation route and each optional transportation parameter. When the similarity between the transportation parameters of at least one transportation route and at least one optional transportation parameter is greater than or equal to the similarity threshold, select the transportation route with the highest similarity as the optimal transportation route for concrete. The similarity between the transportation parameters of each transportation route and each optional transportation parameter is calculated using the cosine similarity method. The specific calculation method of cosine similarity has been publicly disclosed and can be found on the Internet, so it will not be elaborated here.

[0045] The similarity threshold is a benchmark value for judging whether parameters are similar. It is set and adjusted by professionals based on experience and transportation needs, and no specific numerical limit is imposed here.

[0046] S213. When there is no similarity greater than or equal to the similarity threshold, the risk of each transportation route is assessed, and the transportation route with the lowest risk is selected as the best transportation route for concrete.

[0047] The specific process for assessing the risks of each transportation route is as follows: The transportation parameters of each transportation route are divided into transportation data. Each transportation data in each transportation route is compared with each transportation data in each optional transportation parameter. The optional transportation parameter with the smallest difference in transportation data is selected as the target optional transportation parameter for each transportation data in each transportation route. The initial concrete grade in the mapping relationship table between transportation parameters and concrete strength is used as the concrete strength reduction value of each transportation data in each transportation route using the concrete strength reduction value of the target optional transportation parameter. The predicted concrete strength reduction value of each transportation route is calculated.

[0048] Specifically, the process involves: obtaining the difference between each transportation data point in each transportation route and the transportation data point with the smallest difference among the corresponding optional transportation parameters, using this as the minimum difference for each transportation data point in each transportation route; then dividing the minimum difference by each transportation data point to obtain the difference rate for each transportation data point in each transportation route; then dividing the difference rate of each transportation data point in each transportation route by the sum of the difference rates for each transportation data point in each transportation route to obtain the weighting factor for each transportation data point in each transportation route; multiplying the concrete strength reduction value of each transportation data point in each transportation route by the corresponding weighting factor, and then summing these values ​​to obtain the predicted concrete strength reduction value for each transportation route.

[0049] The difference between each transportation data point and the transportation data point with the smallest difference in the corresponding optional transportation parameters is obtained for each transportation route, and the transportation data difference rate of each transportation route is evaluated.

[0050] The mean of the difference rate of each transportation data in each transportation route is calculated to obtain the difference rate of transportation data for each transportation route.

[0051] Based on the predicted concrete strength reduction value and the transportation data difference rate for each transportation route, the risk coefficient of each transportation route is calculated, and the transportation route with the smallest risk coefficient is the transportation route with the lowest risk.

[0052] In this process, the predicted concrete strength reduction value and the transportation data difference rate for each transportation route are normalized and then the mean is calculated. The result is used as the risk coefficient for each transportation route.

[0053] S22. Based on the transportation parameters of the optimal transportation route, predict the state data of concrete in the optimal transportation route, and then select the set of concrete protection measures according to the mapping relationship table between concrete strength and protection measures.

[0054] The specific process for selecting the set of concrete protection measures is as follows: S221. When the optimal transportation route selection method is S212: Obtain the set of effective protection measures under each state data when the initial grade of concrete is used with the transportation parameters that are most similar to the transportation parameters of the optimal transportation route from the mapping relationship table between concrete strength and protection measures. Use this as the set of effective protection measures under each state data. Also, extract the concrete strength reduction value when the initial grade of concrete is used with the transportation parameters that are most similar to the transportation parameters of the optimal transportation route from the mapping relationship table between transportation parameters and concrete strength. Use this as the concrete strength reduction value of the optimal transportation route. S222. Based on simulation test data, extract the state data of the concrete in the vehicle before each protection measure is implemented when the initial grade of concrete is used with the transportation parameters that are most similar to the optimal transportation route transportation parameters. Use this data as the state data of the concrete in the vehicle before each protection measure is implemented for the optimal transportation route reference. S223. Select the set of effective protection measures for the optimal transportation route from the set of effective protection measures for each state data as the set of target protection measures. Based on the concrete strength reduction value of the optimal transportation route, set the sequence interval of the optimal transportation route protection measure set. Select the union of the target protection measure sets within the corresponding sequence interval from the set of target protection measures as the set of concrete protection measures.

[0055] It should be noted that the concrete strength reduction value of the optimal transportation route is divided by the difference between the initial concrete strength and the preset concrete strength benchmark value, which is taken as the reduction ratio. Each set of target protection measures is divided into three sequential intervals, corresponding to reduction ratios of 70%~100%, 35~69%, and 0~34%, respectively. The reduction ratio is compared with the reduction ratios of the three sequential intervals. If the reduction ratio falls within the reduction ratio range of a certain sequential interval, the union of the target protection measures sets in that sequential interval is selected as the concrete protection measures set.

[0056] S224. When the optimal transportation route selection method is S213, the predicted concrete strength reduction value of the optimal transportation route is used to obtain the set of effective protection measures under each state data, and steps S222 and S223 are executed to obtain the set of concrete protection measures.

[0057] S3. During concrete transportation, monitor the condition of the concrete and provide feedback.

[0058] The specific process of step S3 is as follows: S31. Collect concrete status data using the data acquisition device inside the transport vehicle, implement a set of concrete protection measures based on the status data, and collect real-time concrete status data again using the data acquisition device after implementation. S32. Based on the concrete state data before and after execution, analyze the concrete protection effect. When the protection effect is poor, send a signal of poor protection effect to the driver and prompt the driver to deliver the goods as soon as possible.

[0059] Analyze the protective effect of concrete: The state data of concrete before and after implementation are calculated according to the method of calculating the fluctuation rate mitigation value of the state data of each protective measure when each concrete grade is simulated to travel on each simulated transportation route. The fluctuation rate mitigation value of the state data after the implementation of the protective measures is calculated. If the fluctuation rate mitigation value of the state data after the implementation of the protective measures is less than the preset fluctuation rate mitigation value, it indicates that the concrete protection effect is poor, and vice versa.

[0060] The preset state data volatility mitigation value is a benchmark value for judging whether the state data volatility has been mitigated. It is set by a specialist based on experience and transportation needs, and no specific numerical limit is imposed here.
