众所周知，液压支架是支护工作面的重要设备，对保证工作面人员和设备安全具有极其重要的作用。现有的液压支架在工作面上排出一横列，支护工作面顶板，液压支架后方即为顶板不断垮塌的采空区。液压支架交替行走前移，前移过程，液压支架需要降低高度，脱离与顶板接触，此外，液压支架需要与顶板充分接触，液压支架的液压支柱进出口阀处于关闭状态。由于浮化液不可压缩，因此，液压支柱内浮化液液压随顶板下沉而同步变化，通过浮化液液压变化，可以准确的监控顶板下沉情况，但是现有技术浮化液液压传感器，检测的都是乳化泵的出口液压，无法检测承重状态下的液压支柱内浮化液液压变化。本发明填补了现有技术空白，使得工作人员可以通过浮化液液压变化，随时知晓顶板下沉变化。如此设计，有效了保障了工作面的设备和人员的安全。As we all know, hydraulic supports are important equipment for supporting the working surface and play an extremely important role in ensuring the safety of personnel and equipment on the working surface. The existing hydraulic supports are arranged in a row on the working surface to support the roof of the working surface. Behind the hydraulic supports is the goaf area where the roof continues to collapse. The hydraulic support alternately moves forward. During the forward movement, the hydraulic support needs to lower its height and break away from the top plate. In addition, the hydraulic support needs to be in full contact with the top plate, and the hydraulic support inlet and outlet valves of the hydraulic support are closed. Since the floating liquid is incompressible, the hydraulic pressure of the floating liquid in the hydraulic pillar changes synchronously with the sinking of the roof. Through the changes in the hydraulic pressure of the floating liquid, the sinking situation of the roof can be accurately monitored. However, the existing technology of floating liquid hydraulic sensor, What is detected is the outlet hydraulic pressure of the emulsification pump, and it cannot detect changes in the hydraulic pressure of the floating liquid in the hydraulic pillar under load-bearing conditions. The invention fills the gap in the existing technology, allowing workers to know the changes in the sinking of the roof at any time through the hydraulic changes of the flotation liquid. This design effectively ensures the safety of equipment and personnel on the working surface.
作为优化，沿工作面走向方向，自切眼开始，每隔10米，井下监控主机采集一次工作面中段液压支架的液压立柱内部液体压强，得一系列液压立柱内部液体压强——N1、N2、N3……，井下监控主机配有显示屏，在显示屏显示二维坐标，以上述液压立柱内部液体压强——N1、N2、N3为纵坐标，以为采集次序1、2、3……为横坐标，在二维坐标上分别显示相应的点，并顺次连接上述点，形成一条曲线，同时在该二维坐标中用一条横线表示额定最大工作压强，As an optimization, along the direction of the working face, starting from the hole cutting, every 10 meters, the underground monitoring host collects the internal liquid pressure of the hydraulic column of the hydraulic support in the middle section of the working face, and obtains a series of internal liquid pressures of the hydraulic column - N1 , N2 , N3 ..., the underground monitoring host is equipped with a display screen, and the two-dimensional coordinates are displayed on the display screen. The internal liquid pressure of the above-mentioned hydraulic column -N 1 , N2 , N3 is the ordinate, which is the collection order 1, 2 , 3... are the abscissas. The corresponding points are displayed on the two-dimensional coordinates, and the above points are connected in sequence to form a curve. At the same time, a horizontal line is used in the two-dimensional coordinates to represent the rated maximum working pressure.
若所述曲线一直在代表额定最大工作压强的横线以下，平稳波动，说明工作面液压支架工作正常，所述曲线一直处于低位，且很少波动，则说明可能出现工作面顶板大面积不垮塌，需要进行顶板预爆破，If the curve is always below the horizontal line representing the rated maximum working pressure and fluctuates smoothly, it means that the working surface hydraulic support is working normally. If the curve is always at a low level and rarely fluctuates, it means that a large area of the working surface roof may not collapse. , the roof pre-blasting is required,
若所述曲线骤然升高，则进一步判断此时工作面是否推到顶板断层处，若此时工作面恰好推进到顶板断层处，且所述曲线未超过所述横线，则继续推进工作面，同时进一步监控；If the curve suddenly rises, then further determine whether the working surface has been pushed to the roof fault. If the working surface happens to be pushed to the roof fault, and the curve does not exceed the horizontal line, continue to push the working surface. , while further monitoring;
若此时工作面不在顶板断层处，则将该曲线与相邻已开采工作面推进形成曲线进行比较，若二者趋势相符，且所述曲线未超过所述横线，则继续推进工作面，同时进一步监控，If the working face is not at the roof fault at this time, compare this curve with the curve formed by advancing the adjacent mined working face. If the trends of the two are consistent and the curve does not exceed the horizontal line, continue to advance the working face. At the same time, further monitoring
若此时工作面不在顶板断层处，则将该曲线与相邻已开采工作面推进形成曲线相比较，二者趋势不符，且所述曲线有上扬，并有跃过所述横线的趋势和可能，则立即停止工作面推进，工作人员撤离，由专家分析判断无危险后，再工作人员再进入工作面作业。If the working face is not at the roof fault at this time, compare this curve with the curve formed by the advancement of the adjacent mined working face. The trends of the two are inconsistent, and the curve has an upward trend and has a tendency to jump over the horizontal line. If possible, the advancement of the working face will be stopped immediately and the staff will evacuate. After experts analyze and determine that there is no danger, the staff will then enter the working face for work.
如此设计，开挖轨道巷和皮带巷时，有经验的煤矿工作人员可以根据顶板的地质情况，预测出工作面推进过程中顶板下沉方式，进度，利用本发明还可以得到工作面推进过程时承重液压支柱内浮化液液压变化曲线，进而推测出工作面推进顶板下沉变化规模，通过相邻两个采区的曲线对比，可以进一步掌握煤层顶板地质情况，进一步确保采掘安全。Designed in this way, when excavating track lanes and belt lanes, experienced coal mine workers can predict the subsidence mode and progress of the roof during the advancement of the working face based on the geological conditions of the roof. The present invention can also be used to obtain the time of the advancement of the working face. The hydraulic pressure change curve of the floating liquid in the load-bearing hydraulic pillar can then be used to infer the scale of the subsidence change of the working face's advancing roof. By comparing the curves of two adjacent mining areas, we can further understand the geological conditions of the coal seam roof and further ensure mining safety.

Analysis, using the good variable selection ability and prediction ability of the logistic regression algorithm, to predict the fault of each equipment, thereby determining the location, cause, type, and nature of the possible failure, and providing reference suggestions for maintenance.
在弹性网的基础上，建立设备自适应弹性网逻辑回归模型。该模型不仅继承了具备弹性网的稀疏性特性，而且具备更合理的相关特征的群组选择能力。同时，自适应具有Oracle性质，这从本质上保障了这个模型是一个更优的优化模型。自适应弹性网是在弹性网正则化方法的基础上，对L1正则化项中不同的变量系数配给不同的权重，而并不是像弹性网中的L1正则化一样，对变量的非零系数都给予相同的权重。因此，它可以看作是加权了的L1正则化和L2正则化的一个组合。自适应弹性网可以根据变量系数的大小，分别配给它们不同的权重，系数较大的变量配给较小的权重，而系数较小的变量则配给较大的权重，这样使得重要的变量被保留，而不重要的变量则会被去掉。弹性网是L1正则化和L2正则化的一个组合，其表达式如下：On the basis of elastic net, a device-adaptive elastic net logistic regression model is established. This model not only inherits the sparsity characteristics of elastic nets, but also has the ability to select groups with more reasonable related characteristics. At the same time, self-adaptation has Oracle properties, which essentially guarantees that this model is a better optimization model. Adaptive elastic net is based on the elastic net regularization method and allocates different weights to different variable coefficients in the L1 regularization term. It is not like the L1 regularization in the elastic net, all non-zero coefficients of the variables are allocated. given equal weight. Therefore, it can be seen as a combination of weighted L1 regularization and L2 regularization. Adaptive elastic nets can assign different weights to variable coefficients according to their size. Variables with larger coefficients are assigned smaller weights, while variables with smaller coefficients are assigned larger weights, so that important variables are retained. Unimportant variables will be removed. Elastic net is a combination of L1 regularization and L2 regularization, and its expression is as follows:
而自适应弹性网，则是在上式中的L1正则化项的基础上进行加权，得到下面这种正则The adaptive elastic net is weighted on the basis of the L1 regularization term in the above formula to obtain the following regularization
计算弹性网估计值：Compute elastic net estimates:
再按照下面的形式来构造自适应权重向量：Then construct the adaptive weight vector in the following form:
可以得到自适应弹性网逻辑回归模型下的估计值：The estimated value under the adaptive elastic net logistic regression model can be obtained:
对于传统逻辑回归模型：For a traditional logistic regression model:
求L(β)关于(β)的一阶导数和二阶导数，可得：Find the first derivative and second derivative of L(β) with respect to (β), we can get:
令βold和βnew分别表示β的当前估计值和新的估计值，则有下面这个式子：Let βold and βnew represent the current estimated value and new estimated value of β respectively, then there is the following formula:
由此可以看出每次Newton–Raphson迭代实际上就是求解一个加权最小二乘问题，其形式如下：It can be seen that each Newton–Raphson iteration is actually solving a weighted least squares problem, whose form is as follows:
βnew＝argmin(z-XB)TM(z-Xβ)βnew =argmin(z-XB)T M(z-Xβ)
根据传统逻辑回归的求解过程，我们只需对自适应弹性网逻辑回归模型进行变形，就可以得到自适应弹性网逻辑回归模型的迭代形式：According to the solution process of traditional logistic regression, we only need to deform the adaptive elastic net logistic regression model to obtain the iterative form of the adaptive elastic net logistic regression model:
对其稍作变形，得到如下形式：Deform it slightly and get the following form:
坐标下降法的思想是其通过逐个优化解向量的每一维特征(坐标)，实现一次外循环。内循环中，在优化某一坐标时，固β的其余s-1维坐标不动，对该维坐标(不妨设为第j维)求解一系列单变量子问题，即每次求解一个一元函数的极值问题。这一系列一元函数可以表示为：The idea of the coordinate descent method is to achieve an outer loop by optimizing each dimensional feature (coordinate) of the solution vector one by one. In the inner loop, when optimizing a certain coordinate, the remaining s-1 dimensional coordinates of fixed β do not move, and a series of single-variable sub-problems are solved for this dimensional coordinate (which may be set to the jth dimension), that is, a one-variable function is solved each time. extreme value problem. This series of unary functions can be expressed as:
当k＝0时，对f0(β0)求导，并使其导数等于0，就可以得到f0(β0)的最优解。即When k=0, by taking the derivative of f0 (β0 ) and making its derivative equal to 0, the optimal solution of f0 (β0 ) can be obtained. Right now
当k≠0时，由于正则化项中包含需要优化的变量,f0(β0)的情况变得比价复杂，此时，需要对f0(β0)进行整理，使其便于计算。When k≠0, since the regularization term contains variables that need to be optimized, the situation of f0 (β0 ) becomes more complicated. At this time, f0 (β0 ) needs to be organized to make it easy to calculate.
通过计算得到最优解：The optimal solution is obtained through calculation:

If the curve is always at a low level and rarely fluctuates, it means that a large area of the working surface roof may not collapse. , the roof pre-blasting is required,
若所述曲线骤然升高，则进一步判断此时工作面是否推到顶板断层处，若此时工作面恰好推进到顶板断层处，且所述曲线未超过所述横线，则继续推进工作面，同时进一步监控；If the curve suddenly rises, then further determine whether the working surface has been pushed to the roof fault. If the working surface happens to be pushed to the roof fault, and the curve does not exceed the horizontal line, continue to push the working surface. , while further monitoring;
若此时工作面不在顶板断层处，则将该曲线与相邻已开采工作面推进形成曲线进行比较，若二者趋势相符，且所述曲线未超过所述横线，则继续推进工作面，同时进一步监控，If the working face is not at the roof fault at this time, compare this curve with the curve formed by advancing the adjacent mined working face. If the trends of the two are consistent and the curve does not exceed the horizontal line, continue to advance the working face. At the same time, further monitoring

The trends of the two are inconsistent, and the curve has an upward trend and has a tendency to jump over the horizontal line. If possible, the advancement of the working face will be stopped immediately and the staff will evacuate. After experts analyze and determine that there is no danger, the staff will then enter the working face for work.
