The energy consumed by the route tower crane 1 → 2 is as follows: wa-1-2+Wb-2-1Time is Ta-1-2+Tb-2-1。
And analyzing the tower crane which can be plugged downstream of the tower crane which can be plugged in the step , calculating energy consumption W and time T caused by the plugging of different tower cranes, wherein the tower crane for conveying objects to the plugging position is the current main plugging square, at the moment, the tower crane which can be plugged in the step comprises a tower crane 5 and a tower crane 2, and the tower crane which can be plugged in the tower crane 2 comprises a tower crane 4, a tower crane 5 and a tower crane 3.
When the tower crane 4 is the main connection side of the current route, the energy consumption required by the connection of the tower crane 4 and the tower crane 5 is W respectivelya-4-5Time Ta-4-5Tower ofThe energy consumption required by the connection of the crane 5 and the tower crane 4 is respectively Wb-5-4Time Tb-5-4(ii) a The energy consumption required by the connection of the tower crane 4 and the tower crane 2 is W respectivelya-4-2Time Ta-4-2The energy consumption required by the connection of the tower crane 2 and the tower crane 4 is W respectivelyb-2-4Time Tb-2-4;
When the tower crane which can be connected with the tower crane 2 has the tower crane, the energy consumption and the time are calculated by referring to the calculation mode.
At this time, the current routable route and the energy consumption are as follows:
the energy consumed by the route tower crane 1 → 4 → 5 is as follows: wa-1-4+Wb-4-1+Wa-4-5+Wb-5-4Time is Ta-1-4+Tb-4-1+Ta-4-5+Tb-5-4;

If the existing tower crane is used in the planning of the previous step, the planning of the path of the tower crane is considered to enter the complex situation, the complication of the path of the tower crane with other factors and sounds is not eliminated, only the angle that the number of the tower cranes is the minimum can be seen, the path connected to the routes 5 and 3 of the tower cranes can meet the requirement of reaching the end point by using the tower crane 6, namely the path with the minimum number of the tower cranes, but the path with the minimum number of the tower cranes, which is not the path with the minimum energy consumption and the shortest goods time, still needs to be analyzed continuously, when the phenomenon that the used tower cranes are used appears in a certain path during transportation, the situation is not optimal from the aspects of time consumption and energy consumption, and the analysis.
By adopting the method for eliminating the tower crane capable of being connected with the main connecting party in the mode, all the lines of the tower crane 6 connected with each connecting line are selected. The optimal energy-consuming path and the optimal time-consuming path can be quickly selected by the energy-consuming and time-consuming values of the different paths. The part (without a corresponding calculation formula) of the total path for calculating the connection is obtained by progressive accumulation, namely, the total path is obtained by summing the paths of the two tower cranes during the connection. By comparing the paths 2 and 3, the optimal time-consuming path with the minimum number of tower cranes and the optimal time-consuming path with the minimum number of tower cranes can be obtained.
As shown in fig. 3-4, the shortest path problem mentioned above is further illustrated in , when an object needs to be moved from point a to point B, the object can be transported through various paths by a plurality of different tower cranes.
Considering the straight-line distance between two points, in combination with the actual obstacle, the following operations are required:
1. the tower crane 1 firstly lifts an object from the position A, moves the object to a position with the height of H1 and translates the object to a second position;
2. at the moment, the tower crane 2 catcher lifts the object and moves the object to a third position with the height of H3;
3. hoisting the object to a fourth position H6 by a tower crane 5, translating to a fifth position, and then hoisting to the fifth position;
4. and finally, hoisting the object to the position B by a tower crane 6.
The path is shortest in position in the horizontal direction, but displacement in the vertical direction has a reciprocating path due to obstacle crossing. When the height of the obstacle during the moving process exceeds the position height of A, B, the transfer has reciprocating action in the vertical direction. Obviously, the straight-line distance between two points in the transfer process of the tower crane is not an optimal strategy. Therefore, the invention provides the shortest connection path, the most time-saving carrying route, the most energy-saving carrying route and the least connection time carrying route for reference and alternative selection.

, the system also includes a data acquisition unit for acquiring the position and working state of the tower crane, including a crane weight sensor, an amplitude sensor, a height sensor, a moment sensor, a wind speed sensor and an angle sensor, which are arranged on the tower crane.
In other optional examples, in addition to single-factor optimization in practical application, comprehensive optimal decision needs to be considered, at this time, weights of dimensions such as path length, energy consumption, time consumption, occupied tower crane resource number and the like in the optimal decision are set through a system to obtain a customized optimal path, namely, the weights of different optimal routes are preset, a computer device makes a decision after analyzing the weights, optimal routes are provided for carrying, the remaining optimal routes of other dimensions can be sequenced in sequence as alternatives in , intelligent automatic decision can be realized, and the step of artificial decision is omitted.
Exemplary embodiments of the present disclosure are specifically illustrated and described above.
