Example 1

Referring to FIG. 1 , the first embodiment of the present invention provides a method for optimizing the processing of an array-type drill row, an embodiment of which includes but is not limited to the following steps:

Step S100, receiving the hole position information to be processed and the drill bit information.

In this embodiment, the step of receiving the hole position information to be processed and the drill bit information of the drill row is the basic premise of the processing optimization of the row drill.

Step S200, performing a calculation optimization process according to the hole position information to be processed and the drill bit information to obtain the drill row processing information.

In this embodiment, in this step, according to the received hole position information to be processed and the drill bit information, based on the principle of an optimal algorithm, and according to the hole position information to be processed, the movement trajectory of each row drill bit when working is calculated. , so as to obtain the corresponding drilling processing information.

Step S300 , controlling the drilling row to perform processing based on the drilling row processing information.

In this embodiment, this step is based on the processing information of the drill row obtained above, so that the row drill can be controlled for processing, so that each row drill bit can move according to the optimal working path, and the number of processing times of the row drill can be reduced. , the moving distance of the row drill is short, which greatly improves the processing efficiency of the row drill.

Referring to FIG. 2 , in this embodiment, a first row of drill packs 400 and a second row of drill packs 500 are provided in an array drill row. The array drill has multiple rows of drills, each row of drills can move in the X direction, and each row is divided into two sets of drill bags, the first drill bag 400 and the second drill bag 500, which can independently move in the Y direction. The present invention can ensure that the hole positions need to be processed according to the XY plane, and under the condition that each row drilling bag is within the defined feasible area and does not collide with each other, the processing position of each row drilling bag can be automatically configured. When the drilling pack (processing once) cannot process all the holes, the position of the drilling pack is automatically configured for many times (reprocessing), which can ensure that the number of processing is small, and the moving distance of the drilling pack is small, thereby improving the processing efficiency.

In step S200 of this embodiment, the following steps may be included but not limited to:

In this embodiment, according to the received hole position information to be processed and the drill bit information, this step uses a drill row processing optimization algorithm to perform calculation and optimization processing, and calculates the best working path of each row drill bit.

In this embodiment, the drilling optimization algorithm can be expressed as:

The constraints of the drilling optimization algorithm can be expressed as:

k _i,j ∈R _x,i,j ,p _i,j ∈R _A,i,j ,q _i,j ∈R _B,i,j

i=1,2,...,M

j=1,2,...,N

Indicates that the jth row of drills in the ith processing is in

and

The number of holes that can be machined at the position; n represents the total number of holes to be machined; (Ex _i,j ,Ey _i,j,A ,Ey _i,j,B ) indicates the jth row in the ith processing The desired position of the drill in the x-direction and its first row of drill packs and the second row of drill packs in the y-direction; (Ex _0,j ,Ey _0,j,A ,Ey _0,j,B ) indicates the first machining The j-th row of drills in the x-direction and its first and second row of drill packs in the y-direction desired positions. In this algorithm, M is minimized, and k _i,j , p _i,j , q _i,j that minimize J are obtained when M is the smallest.

Further, in order to reduce the calculation time, the greedy method is used for the optimization algorithm of drilling row processing to resolve it into another optimization problem:

Optimization objective: sequentially solve the maximum value when i=1,2,...,M

Constraints: Same as above.

In order to further reduce the time consumption, the optimization problem for Ji mentioned above is resolved into a _nested optimization problem:

Optimization objective 1: For a given

ask to make

maximum, and at

Find the maximum p _i,j , q _i,j that maximize the following equations.

Restrictions:

p _i,j ∈R _A,i,j ,q _i,j ∈R _B,i,j

j=1,2,...,N

Optimization goal 2: find such that

maximum, and _ki,j that maximizes the following equation under the maximum of J _i .

Restrictions:

k _i,j ∈R _x,i,j

j=1,2,...,N

For the above optimization goal 1, the exhaustive search method is used to solve it; for the above optimization goal 2, since the optimization problem still has N-dimensional search, in order to further reduce the amount of calculation, the greedy strategy can be used again, that is, to calculate R _x,i,j all in the collection

And arrange them in descending order, and remove the T (T is a set integer) after the

corresponding k _i,j , thus ensuring that the number of searches is not greater than T ^N times.

It can be seen from the above scheme that the information of the holes to be processed and the drill bit information are first received, and then the calculation and optimization processing is performed according to the received information of the holes to be processed and the drill bit information, so as to obtain the drilling processing information. The drill processing information controls the drill row to perform processing. Through the above method, the processing times of the row drill can be reduced and the moving distance of the row drill can be shortened, which greatly improves the processing efficiency.
