And 3, after the slurry inlet mechanical arm 16 reaches the position near the slurry inlet 12 (the specific range can be set by self, for example, when the distance is less than 40cm, the position is considered to reach the position near the slurry inlet 12), the electric cabinet 9 detects the accurate position of the slurry inlet 12 through the camera 6 arranged on the slurry inlet mechanical arm 16, and drives the slurry inlet mechanical arm 16 to insert the grouting pipe into the slurry inlet 12.
After the grout outlet mechanical arm 7 reaches the position near the grout outlet 3 (the specific range can be set by oneself, for example, when the distance is less than 40cm, the position is considered to be near), the electric cabinet 9 detects the accurate position of the grout outlet 3 through the camera 6 arranged on the grout outlet mechanical arm 7, and drives the grout outlet mechanical arm 7 to insert a grouting pipe into the grout outlet 3.

Preferably, in the moving process, the image information of the obstacle acquired by the camera 6 is subjected to multi-stage operation of the convolutional neural network, and then the obstacle avoidance is performed. As shown in fig. 3, the convolutional neural network has the advantages of avoiding display feature extraction, deeply learning from training data, simplifying complex preprocessing of images, and greatly improving the operation speed of the model by performing multi-layer operation. Specifically, after the high-definition camera acquires the picture information of the obstacle, the final output is obtained through the multi-stage operation of the convolutional neural network:
a1=t11x1+t12x2+t13x3+b1
a2=t21x1+t22x2+t23x3+b2
a3=t31x1+t32x2+t33x3+b3
hp=t11a1+t12a2+t13a3+b1
x1、x2、x3is the input of the system (i.e. picture information), a1、a2、a3Is the output of each layer of the system, hpThe final output result, and other parameters are constant coefficients of each layer, which can be given, and since the convolutional neural network is a prior art, it is not described herein again. The convolutional neural network trained by a large amount of sample data can detect all images to be detected with the minimum calculation cost, can be widely applied to target detection and is a key step for avoiding obstacles.
Preferably, when the convolutional neural network is used for image processing, the activation function softmax can be cited to introduce a nonlinear factor into the neuron, so that the neural network can arbitrarily approximate any nonlinear function, and the neural network can be applied to a plurality of nonlinear models. It can "compress" a delta-dimensional vector x containing arbitrary real numbers into another delta-dimensional real vector f (x) such that each element ranges between (0, 1) and the sum of all elements is 1.
The automatic control closed loop grouting robot system is provided with a plurality of sensors, including a grout outlet mud flowmeter, a liquid level meter, a mud density detector, a grout inlet mud flowmeter, a pressure sensor and the like, so that the automation and the intelligentization degree of the robot system are greatly improved.
