[0041] The specific implementation of the present invention is described below in conjunction with the accompanying drawings to facilitate the understanding of the present invention by those skilled in the art. Obviously, the present invention is not limited to the scope of the specific implementation. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention defined and determined by the attached claims, these changes are non-creative work, and all inventions and creations using the invention concept of this law are protected.

[0042] Example 1

[0043] This embodiment provides a transport organization mode calculation study specifically for the intelligent sky rail, which can solve the tracking interval, number of trains and operation routes required by the intelligent sky rail under different input conditions.

[0044] This embodiment analyzes and studies the tracking intervals of different marshalings in different scenarios, and studies the station loading and unloading vehicles and sections (trains running on straight tracks, trains running on 60‰ straight sections, and trains running on light bulb lines) respectively, so as to determine the minimum tracking interval for the entire line.

[0045] (1) Minimum tracking interval for station loading and unloading scenarios.

[0046] like Figure 1 As shown in the figure, the minimum tracking interval for loading and unloading vehicles at the station is to ensure that the following vehicle entering the station is not forced to slow down or wait outside the station. It is broken down into five parts according to the tracking interval capacity of the signal system, including error time, stop time, exit time, equivalent time in the parking area, common braking time, etc.

[0047] T1=T 误差 +T 停站 +T 出站 +T 等效 +T 制动

[0048] Among them, T1 represents the minimum tracking interval of the loading and unloading vehicles at the station, T 误差 Indicates the system error time, T 停站 Indicates the train stop time, T 出站 Indicates the train departure time, T 等效 represents the equivalent time of parking area, T 制动 Indicates the normal braking time.

[0049] T 误差 According to general experience, take 5s;

[0050] T 停站 Determined according to the actual loading and unloading process and transportation volume demand, take 40s;

[0051] Where L 车is the vehicle length, m is the number of train formations, a is the heavy vehicle traction acceleration, a is determined according to the vehicle traction performance and traction weight, L 站台 is the length of the platform protection zone, L 站台 According to general experience, 12m is taken;

[0052] Where V 设计 is the line design speed, which is 50km / h;

[0053] where a 制动 is the common braking rate, take 0.87m / s 2 .

[0054] The calculation is shown in Table 1 below. The principle is as follows Figure 1 shown.

[0055] Table 1

[0056]

[0057]

[0058] (2) Minimum tracking interval for interval scenarios.

[0059] like Figure 2 As shown in the figure, the minimum tracking interval of a train in a section is to ensure that the following train is not forced to slow down or stop in the section. It should be based on the interval time maintained with the leading train and is decomposed into four parts according to the tracking interval capacity of the signal system, including error time, braking distance passing time, protection section passing time, and leading train clearance time.

[0060] Minimum tracking interval T2 = T 误差 +T 制动 +T 出清 +T 通过 ;

[0061] Among them, the error time T 误差 According to general experience, take 5s;

[0062] Braking distance time Braking distance X 制动 According to the slope and vehicle braking rate, the braking distances of vehicles on straight roads, 60‰ straight sections, and lightbulb lines are 159.64m, 514.4m, and 17.74m respectively; the corresponding vehicle speed limits are 60km / h, 60km / h, and 20km / h respectively;

[0063] Front car clearing time Determined according to the train length, train formation number and vehicle speed limit;

[0064] Passing time of protected area Determined based on the length of the protected area and the vehicle speed limit.

[0073] (3) Determine the number of vehicle groups based on the transportation needs in different scenarios to ensure transportation capacity.

[0074] When determining the number of vehicles in the intelligent sky rail system, multiple factors need to be considered, including but not limited to transportation volume, passenger or cargo density, operational efficiency, cost-effectiveness, and the maximum capacity of the system design. The specific steps are as follows:

[0075] Transport demand analysis: First, a detailed analysis of the daily, peak and special period transport demand of each station and the entire line is carried out. This includes data such as passenger flow, cargo weight and volume, as well as forecasts of growth trends in the next few years.

[0076] Marshalling efficiency evaluation: Based on transportation demand, evaluate the operational efficiency under different marshaling numbers. For example, increasing the marshaling can increase the capacity of a single transport, but it may also lead to problems such as longer station stay time and increased energy consumption.

[0077] Cost-benefit analysis: Calculate the operating costs (such as energy consumption, maintenance costs, labor costs, etc.) and benefits (such as the income from increased transportation volume) under different numbers of trains. By comparison, find the most cost-effective train plan.

[0078] System compatibility check: Ensure that the selected marshaling number is compatible with existing and planned station, track, signal system and other infrastructure to avoid unnecessary transformation or upgrade costs.

[0079] Flexibility considerations: Taking into account future changes in transportation demand, choose a marshaling scheme with a certain degree of flexibility so that it can be quickly adjusted when demand increases or decreases.

[0080] (4) Conduct train operation route analysis based on operational organization requirements and determine the type of route to be operated.

[0081] The design of train routes directly affects the efficiency, passenger satisfaction and operating costs of the transportation system. When determining the type of route to be operated, factors such as line layout, passenger travel demand, and operating strategy need to be considered comprehensively. The specific steps are as follows:

[0082] Line layout analysis: Detailed analysis of the physical layout of the line, including station locations, section lengths, slopes, curve radii, etc., to determine which sections are suitable for operating different types of routes.

[0083] Passenger demand analysis: Collect passengers' travel demand information through surveys and statistics, including starting station, terminal station, travel time, travel frequency, etc., to understand passengers' demand for transportation services.

[0084] Route scheme design: Based on the line layout and passenger demand, design a variety of possible route schemes, such as direct routes, interval routes, nested routes, etc., and evaluate the advantages and disadvantages of each scheme.

[0085] Operation strategy considerations: Select the most appropriate route plan based on the operation goals (such as improving transportation efficiency, reducing costs, and improving passenger satisfaction). For example, a high-frequency, short-route operation strategy can be adopted during peak hours to ease congestion; a low-frequency, long-route strategy can be adopted during non-peak hours to reduce operating costs.

[0086] Simulation and evaluation: Use simulation software to simulate the selected route plan, evaluate its impact on transportation efficiency, passenger waiting time, operating costs, etc., and make adjustments and optimizations based on the simulation results.

[0087] Flexibility and adaptability: Ensure that the route plan has a certain degree of flexibility and adaptability so that it can be quickly adjusted according to future line expansion, changes in passenger demand, etc.

[0088] Route design principles: (1) Under the premise of meeting the needs of the operation organization, the number of vehicles should be reduced as much as possible to save vehicle purchase costs, reduce operating costs and improve operating efficiency; (2) The route settings of each design year should be kept as continuous as possible, and the operability of operation management and the flexibility of operation organization should be considered.

[0089] According to the loading and unloading transportation mode of the sky rail system, one route is opened for the whole line, that is, the train operation route from the Toksun end loop line to the mining area loading loop line. It is easy to manage and has a high service level. It is the simplest and ideal operation plan.
