统计其高频信号范围覆盖范围内的中控节点到该中控节点的传输时间，信号传输时间长，则货运时间长，信号传输时间短，则货运时间短，可以用信号传输时间代替货运时间，得到的最短路径为货运的最短路径，将传输时间与对应的两个中控节点一一映射，得到货运路径预先统计结果；Calculate the transmission time from the central control node within the coverage of its high-frequency signal to the central control node. If the signal transmission time is long, the freight time will be long. If the signal transmission time is short, the freight time will be short. The signal transmission time can be used to replace the freight time. , the shortest path obtained is the shortest path of freight, and the transmission time is mapped one by one to the corresponding two central control nodes to obtain the pre-statistical results of the freight path;
确定货运传输路径中每个中控节点的下一个中控节点；Determine the next central control node for each central control node in the freight transmission path;
从货运传输路径初始的中控节点开始，根据货运路径预先统计结果，统计中控节点到下一个中控节点的时间，直到货运传输路径末端的中控节点；Starting from the initial central control node of the freight transmission path, based on the pre-statistical results of the freight path, the time from the central control node to the next central control node is counted until the central control node at the end of the freight transmission path;
累加货运传输路径中所有的中控节点到下一个中控节点的时间，得到货运传输路径的长度。Accumulate the time from all central control nodes in the freight transmission path to the next central control node to obtain the length of the freight transmission path.
参照图5所示，均匀负载法具体如下：Referring to Figure 5, the uniform load method is as follows:
确定中控节点到目标目的地的至少一个传输路径；Determine at least one transmission path from the central control node to the target destination;
统计每个传输路径中的目的地的货运负载，累加货运负载，得到传输路径的总货运负载；Count the freight load of the destination in each transmission path, accumulate the freight load, and obtain the total freight load of the transmission path;
货运负载大，而每条线路的货运限额固定，则等待上船运输的时间长；The freight load is large and the freight quota for each line is fixed, so the waiting time for boarding and transportation is long;
选择总货运负载最小的传输路径作为中控节点到目标目的地的目的地传输路径，可以保证对已有的负载高的目的地的使用，避免堵塞。Selecting the transmission path with the smallest total freight load as the destination transmission path from the central control node to the target destination can ensure the use of existing destinations with high loads and avoid congestion.
上述国际运输散货全程订单轨迹系统的工作过程为：The working process of the above-mentioned international bulk cargo full order tracking system is as follows:
步骤一：调度模块根据货运传输信息需要传输至的目标目的地，确定目标目的地所在位置，调度模块确定最短的货运传输路径作为货运传输信息的传输路径；Step 1: The dispatch module determines the location of the target destination according to the target destination to which the freight transmission information needs to be transmitted. The dispatch module determines the shortest freight transmission path as the transmission path of the freight transmission information;
步骤二：货运模块发出货运传输信息至中控节点模块，中控节点模块根据货运传输信息的传输路径，传输货运传输信息至目标目的地所在中控节点；Step 2: The freight module sends the freight transmission information to the central control node module. The central control node module transmits the freight transmission information to the central control node where the target destination is located according to the transmission path of the freight transmission information;
步骤三：调度模块统计中控节点下属目的地的货运负载，调度模块使用均匀负载法，规划目的地传输路径；Step 3: The dispatch module counts the freight load of the destinations under the central control node. The dispatch module uses the even load method to plan the destination transmission path;
步骤四：中控节点模块根据目的地传输路径，确定离货物最近的中控节点，由该中控节点的GPS定位对货物进行定位显示。Step 4: The central control node module determines the central control node closest to the goods based on the destination transmission path, and uses the GPS positioning of the central control node to position and display the goods.
一种存储介质，其上存储有计算机可读程序，所述计算机可读程序被调用时储存上述的国际运输散货全程订单轨迹系统。A storage medium on which a computer-readable program is stored. When the computer-readable program is called, the above-mentioned entire order trajectory system for international transportation of bulk cargo is stored.
可以理解的是，适用于上述系统的存储介质可以是磁性介质，例如，软盘、硬盘、磁带；光介质例如，DVD；或者半导体介质例如固态硬盘SolidStateDisk，SSD等。It can be understood that the storage media suitable for the above system can be magnetic media, such as floppy disks, hard disks, tapes; optical media, such as DVD; or semiconductor media, such as solid state disks, SolidStateDisk, SSD, etc.
综上所述，本发明的优点在于：通过设置调度模块、中控节点模块和货运模块，对于任意的起始点和目标目的地，能综合考虑货运的等待时间和货运的运输时间，选择出货运线路短和货运负载低的线路，避免因为货运线路场和货运负载高，而导致货运出现等待时间长或货运时间长的情况，保证货运传输轨迹的最小时间性。To sum up, the advantage of the present invention is that by setting up the scheduling module, the central control node module and the freight module, for any starting point and target destination, the waiting time of the freight and the transportation time of the freight can be comprehensively considered, and the freight can be selected. Lines with short lines and low freight loads can avoid long waiting times or long freight times due to high freight lines and high freight loads, and ensure the minimum timeliness of freight transmission trajectories.
