[0030] The freight track detection time periods are numbered in sequence. Indicates the number of the freight track detection time period, , Indicates the total number of timeslots for freight track detection.

[0031] Furthermore, the specific process of evaluating the first performance of the freight trajectory of the station by using the freight trajectory parameters is as follows: obtaining the cargo loading annotation parameters of the truck freight; obtaining the freight estimated time value annotation parameters and the freight business required transportation time parameters; and thereby comprehensively analyzing to obtain the negative index of the first performance analysis of the freight trajectory.

[0032] In this embodiment, the negative index of the first performance analysis of the freight track is used to describe the level of efficiency evaluation of the freight track between stations. The specific analysis formula of the negative index of the first performance analysis of the freight track is as follows: ; ; Indicates The first performance analysis negative index of the freight trajectory of the preset freight trajectory.

[0033] Indicates The first of the preset shipment tracks The cargo loading rate of each freight trajectory section. In actual freight transportation, the cargo loading rate is the value of the actual cargo volume divided by the maximum cargo volume of the carriage.

[0034] Indicates The first of the preset shipment tracks The estimated arrival time of freight for each freight trajectory segment, Indicates The first of the preset shipment tracks The freight estimated start time value, freight estimated arrival time value and freight estimated start time value of each freight trajectory section are directly extracted from the freight trajectory generation and estimation database.

[0035] Indicates The first of the preset shipment tracks The total transportation time required for freight business on each freight trajectory segment.

[0036] Indicates the traffic peak time correction factor, the value range is ,Under different freight estimated arrival time values ​​and freight estimated start time values, the freight transportation efficiency of different freight trajectory sections will be different. The higher the degree of overlap between the traffic peak time and the freight estimated arrival time value and the freight estimated start time value, the higher the traffic peak time correction factor.

[0037] In a specific embodiment, a mapping set is established by using the estimated freight arrival time value and the estimated freight start time value in the historical freight trajectory data and the traffic peak time correction factor, and the real-time estimated freight arrival time value and the estimated freight start time value are input into the pre-set mapping set to obtain the corresponding traffic peak time correction factor.

[0038] Indicates The first of the preset shipment tracks The traffic operation index of a freight trajectory section is a conceptual index value that comprehensively reflects the smoothness or congestion of the road network.

[0039] The specific data of the traffic operation index adopts the Beijing "Urban Road Traffic Operation Evaluation Index System" (DB11 / T785-2011), which mainly uses the travel speed and road network weight to calculate the congestion mileage ratio of each level of road section, road and road network. Then, according to the relationship between the road network severe congestion mileage ratio and the road traffic operation index, they are normalized and converted to each other (that is, different road network congestion mileage ratios are converted into different road traffic operation index values). Its operation status is divided into five levels: "smooth, basically smooth, light congestion, moderate congestion and severe congestion", with a value range of The traffic operation index values ​​of roads of different grades are different.

[0040] For example, the operation indexes of the five traffic operation states in Beijing are , , , and , and the corresponding road network congestion mileage ratios are , , , and , if the road network congestion mileage ratio exceeds , then the traffic operation index is .

[0041] like Figure 3 As shown, it is a schematic diagram of the analysis formula function image of the first performance analysis negative index of the freight trajectory provided in the embodiment of the present application; if the traffic peak time correction factor is set to , if the cargo loading rate is set to , the traffic operation index is taken as the independent variable and the negative index of the first performance analysis of freight trajectory is taken as the dependent variable; Figure 2 Function curve in , ,express and and , function curve Indicates when and and The analytical formula function graph of the first performance analysis of the freight trajectory at the time of negative exponent is shown as a schematic curve.

[0042] Figure 2 Function curve in , ,express and and , function curve Indicates when and and The analytical formula function graph of the first performance analysis of the freight trajectory at the time of negative exponent is shown as a schematic curve.

[0043] Figure 2 Function curve in , 6, indicating and and , function curve Indicates when and and The analytical formula function graph of the first performance analysis of the freight trajectory at the time of negative exponent is shown as a schematic curve.

[0044] It can be seen from the figure that when the traffic operation index increases, it means that the road network planned by the freight trajectory is becoming more and more congested, and the negative index of the first performance analysis of the freight trajectory also increases.

[0045] when and The value of is the same as When the values ​​are different, The larger the value, that is, the longer the estimated arrival time of the freight, the longer the freight is expected to take. At this time, the negative exponential upward trend of the first performance analysis of the freight trajectory becomes faster.

[0046] when and The value of is the same as When the values ​​are different, The smaller the value, that is, the less total transportation time required by the freight business, which means that the estimated time allowed for freight transportation is shorter, and the second negative index of power enterprise management data security rises faster.

[0047] If the traffic operation index is small, the negative index of the first performance analysis of freight trajectory will increase dramatically with the changes of other influencing factors. As the traffic operation index continues to increase, that is, when the current traffic is becoming more and more congested, the negative index of the first performance analysis of freight trajectory will gradually slow down with the changes of other influencing factors. When the traffic operation index reaches a maximum value, the negative index of the first performance analysis of freight trajectory will still increase, but the growth trend is the smallest, which is in line with the objective situation of time freight.

[0048] Furthermore, the specific process of evaluating the second performance of the station freight trajectory by using the freight trajectory parameters is: obtaining the freight vibration impact annotation parameters of the truck freight; obtaining the freight vibration impact parameters of the truck freight and the road surface area parameters of the truck freight trajectory through the freight trajectory second performance parameter acquisition unit; and obtaining the negative index of the freight trajectory second performance analysis by comprehensive analysis.

[0049] In this embodiment, the negative index of the second performance analysis of the freight track is used to describe the safety assessment level of the freight track between stations. The specific analysis formula of the negative index of the second performance analysis of the freight track is as follows: ; ; Represents a natural constant.

[0050] Indicates The second performance analysis negative index of the freight trajectory of the preset freight trajectory.

[0051] Indicates The first of the preset shipment tracks The first section of the freight track The maximum value of freight vibration impact force during the freight trajectory detection period.

[0052] Indicates The first of the preset shipment tracks The first section of the freight track The number of freight vibration impacts in a freight trajectory detection period.

[0053] It indicates the historical average value of freight vibration impact force; Indicates the historical average number of freight vibration impacts.

[0054] Indicates The pavement condition index of a preset freight track is used to describe the degree to which the pavement structure remains intact.

[0055] Indicates The first of the preset shipment tracks The first section of the freight track The damaged road area during the freight trajectory detection period.

[0056] Indicates The first of the preset shipment tracks The first section of the freight track The total road area during the freight trajectory detection period.

[0057] Table 1 is an example table of negative indexes of the second performance analysis of freight trajectories. The example parameters in Table 1 are only taken from parameters under a preset freight trajectory, a freight trajectory section, and a freight trajectory detection time period for illustration. Table 1 is shown below.

[0058] Table 1 Example of negative index of the second performance analysis of freight trajectory

[0059] According to Table 1, if the road condition index becomes smaller, it means that the road condition is poor at this time, and the freight passing through this place will inevitably have greater vibration and impact, and the safety risk of freight transportation will increase. At this time, the negative index of the second performance analysis of the freight trajectory will become larger; if or It decreases, indicating that the freight vibration impact of this freight track section of the preset freight track is relatively weak. At this time, the negative index of the second performance analysis of the freight track becomes smaller. and All of them decrease, indicating that the freight vibration impact on this section of the preset freight trajectory is relatively weaker. At this time, the negative index of the second performance analysis of the freight trajectory decreases more. Comprehensive evaluation of the above factors makes it easier to quantitatively evaluate the negative index of the second performance analysis of the freight trajectory.

[0060] Furthermore, the specific process of comprehensively analyzing the first negative index of the freight trajectory performance analysis and the second negative index of the freight trajectory performance analysis to obtain the third negative index of the freight trajectory performance analysis is as follows: the third negative index of the freight trajectory performance analysis is obtained by analyzing the first negative index of the freight trajectory performance analysis and the second negative index of the freight trajectory performance analysis through an analysis formula; the specific analysis formula of the third negative index of the freight trajectory performance analysis is as follows: ; ; Number the preset freight tracks in sequence. Indicates the number of the preset freight track, , Indicates the total number of numbers for the preset freight tracks; Indicates A negative index of the first performance analysis of the freight track of the preset freight track; Indicates A negative index of the second performance analysis of the freight track of the preset freight track; Indicates The third performance analysis negative index of the freight track of the preset freight track; Analyzing negative impact factors for a first performance of a preset freight trajectory obtained from a freight trajectory generation and estimation database; A negative influencing factor is analyzed for a second performance of a preset freight trajectory obtained from a freight trajectory generation and estimation database.

[0061] In this embodiment, the third performance analysis negative index of the freight trajectory is used to describe the comprehensive risk negative assessment level of the freight trajectory between sites.

[0062] In a specific embodiment, a mapping set is established by combining weather and climate data in historical freight trajectory data with the first negative impact factor of freight trajectory performance analysis and the second negative impact factor of freight trajectory performance analysis, and real-time weather and climate data are input into a pre-set mapping set to obtain the corresponding first negative impact factor of freight trajectory performance analysis and the second negative impact factor of freight trajectory performance analysis; the worse the weather and climate, the priority is given to ensuring freight safety, and at this time, the higher the negative impact factor of the second performance analysis of freight trajectory, the lower the negative impact factor of the first performance analysis of freight trajectory.

[0063] Furthermore, the specific process of comparing and analyzing the negative index of the third performance analysis of the freight trajectory with the corresponding threshold is as follows: if the negative index of the third performance analysis of the freight trajectory is greater than the third performance threshold of the freight trajectory, then the negative index of the third performance analysis of the freight trajectory is judged to be unqualified for the preset freight trajectory, and the unqualified preset freight trajectory is removed; if the negative index of the third performance analysis of the freight trajectory is not greater than the third performance threshold of the freight trajectory, then the negative index of the third performance analysis of the freight trajectory is judged to be qualified for the preset freight trajectory, and the qualified preset freight trajectory is retained; the negative indexes of the third performance analysis of the retained preset freight trajectories are arranged in descending order, and the freight trajectory corresponding to the smallest negative index of the third performance analysis of the freight trajectory is recorded as the preferred freight trajectory.

[0064] Furthermore, the freight trajectory corresponding to the smallest freight trajectory third performance analysis negative index is recorded as the preferred freight trajectory, which also includes: taking the preferred freight trajectory as the freight trajectory selected for judgment, and transporting freight along the preferred freight trajectory through freight transportation equipment; during the freight transportation process, obtaining a new freight trajectory third performance analysis negative index for the preferred freight trajectory through the freight trajectory third performance analysis module according to the freight trajectory detection time period; if the new freight trajectory third performance analysis negative index is not greater than the freight trajectory third performance threshold, then no adjustment is made; if the new freight trajectory third performance analysis negative index is greater than the freight trajectory third performance threshold, then the freight trajectory third performance analysis negative index is re-arranged in descending order, and the freight trajectory corresponding to the smallest freight trajectory third performance analysis negative index is recorded as the new preferred freight trajectory.

[0065] In this embodiment, the third performance threshold of the freight trajectory is directly extracted from the freight trajectory generation and estimation database.

[0066] Furthermore, comparing and analyzing the negative index of the third performance analysis of the freight trajectory with the corresponding threshold value also includes: if the negative index of the third performance analysis of the freight trajectory is greater than the third performance threshold value of the freight trajectory, then judging that the preset freight trajectory corresponding to the negative index of the third performance analysis of the freight trajectory is unqualified, and clearing the unqualified preset freight trajectory; if all preset freight trajectories are cleared, that is, the negative index of the third performance analysis of the freight trajectory corresponding to all preset freight trajectories is greater than the third performance threshold value of the freight trajectory, then sending the negative index of the third performance analysis of the freight trajectory and the freight trajectory early warning notification of all preset freight trajectories to relevant personnel, and making adjustments.
