A gas-liquid cooling system for mold production, comprising:
the pipeline path module is used for selecting an optimal cooling loop according to each pipeline path in the cooling device;
the monitoring module is used for detecting the temperature in the device at the moment in real time;
the pressure drop module is used for detecting the pressure of the cooling device along with the change of the temperature;
and the data storage module is used for storing the cooling data and the path information and performing self optimization by utilizing the learning nerves.
In one embodiment, the arrangement information of the whole cooling device is firstly input into the pipeline path module, the specific positions of each tool and each pipeline are obtained, the positions of an inlet and an outlet are marked, the obstacle condition for limiting the path is determined in the actual space, and a path model is further established; thus sorting out different permutation and combination and coding to obtain an initial path set; determining a decoding mode according to each actual parameter of each path; in practice, different cross paths exist in the pipeline, so that the optimal combination on each sub-path is selected, and the higher the cross probability of the path is, the earlier the optimal path is combined; the path of greatest fitness is selected from these optimal combinations as the cooling channel.
Specifically, since a cooling circuit inside the pipe is composed of one or several sections of cooling pipes, the inlets for the cooling liquid and the fresh water into the cooling device, which can receive the cooling medium, are generally selected by default near the gates, or the inlets of the cooling pipes can be designated by the user; starting from an inlet, enabling the cooling medium to be perpendicular to an inlet face, obtaining a section of pipe path without involvement in unit length forward, enabling the cooling medium to move in five directions (up, down, left and right front) next to the cooling medium, and as the optimal path is needed, enabling the number of broken lines to be as small as possible, preferentially judging the next section of pipe path which meets the direction of the existing pipe path, namely searching in the forward direction (if the forward direction is a turning point, the turning point is not described), storing the pipe path in the forward direction into a path set, and if the pipe path continues to extend in the forward direction and interferes with a die part mounting hole or a pipe, selecting other directions to extend and marking the node; when a next path is selected each time, the current path position is a mother node, the next position is a child node, the mother node can have 0-5 child nodes, when a node finds that the node reaches a path which can not advance in five directions, the previous mother node is returned, the path is marked as an unavailable path, and therefore the path is not selected in the subsequent path selection; therefore, the path segment generated from a certain fixed inlet can form a branch structure like an oak tree branch; the system stores the generated information of each path by using a tree structure; after the tree structure is formed, the parent node of each node is searched through traversal, and the longest path is found to be used as the optimal path of the final cooling pipeline.
More specifically, in a specific operation, the arrangement of different parts inside the cooling device affects the selection of the path, and becomes an obstacle to the interference selection of the optimal path; dividing the space occupied by the objects into a plurality of geometric units, and determining the position relation among the objects by judging whether the geometric units are overlapped; or whether the two objects occupy the same unit is judged so as to judge whether the two objects interfere with each other; because more or less pipelines exist in the device, whether the interference occurs is judged by solving whether the minimum distance between the curved surfaces meets the distance requirement or not according to the curved surface model and the parameters of the known pipeline; fitting the curved surface by using triangular surface patches, calculating the mutual distances between the triangular surface patches, and selecting the minimum value as the minimum distance between the curved surface and the curved surface; thereby solving for the minimum distance between the surface of the cooling duct and the mounting hole of the die part; information of the surface of the interference hole is obtained by traversing the part mounting hole in the die, and information of the pipeline is obtained by traversing the cooling pipeline; judging whether the cooling pipeline and the die are interfered by calculating whether the minimum distance between the surface of the interference hole and the outer surface of the pipeline is larger than a required critical value; the same principle can be used to determine whether the minimum distance principle is satisfied between the cooling pipes.
In one embodiment, the data storage module stores the path information and the pipeline temperature data after each cooling operation; under a communication network, a device selects a path from all selectable paths, connects a source node and a destination node as a communication strategy, and determines an optimal path; randomly initializing the weight and bias of the whole network within a threshold range, allowing data of an input layer to pass through the network layer by layer, and entering an error reverse transmission stage when a large deviation exists between the output and the real output of the network; the error is reversely transmitted layer by the output layer, and then the weight and the bias of each layer are updated to reduce the error; in a complete path data, the learning neuron in the data storage module decomposes the data, extracts a data set available for related information and stores the data set in a training database; and the training database extracts path characteristics and performs combined operation, and the obtained result is stored in the pipeline path module, so that the subsequent path selection is optimized.
Specifically, when each time the path data is transmitted to the data storage module, the learning neuron extracts relevant information from the data and applies the relevant information to the training neuron from a series of available data sets; training a neuron to initialize input data by using a deep convolutional network, performing a characteristic extraction process, adjusting a deep learning network, training input data successively on each layer of the neural network, passing each step through an old deep learning system and a network hidden layer, and after the steps are completed, adjusting the weight of each layer to minimize the output error of the deep learning system until a final value is given after the requirements are met; in addition to the training process being performed when there are multiple communication networks or sub-communication networks in the device, each network needs to train the deep learning system according to the number of destination nodes, because there are multiple nodes in one path data, so that many destination addresses extend, and therefore each deep learning system has and can only predict a node close to it during operation.
More specifically, after training data is completed, self communication traffic is transmitted to the sub communication networks through the communication networks, then each sub communication network uses a weight matrix to create a deep learning system to predict an adjacent network, the step is repeatedly executed until path information is required to be obtained, all possible paths can be operated by using the weight matrix data, and through the deep learning system, the prior path experience can be learned to obtain an optimal communication path instead of congestion caused by a default shortest path; the obtained learning data can be transmitted to the pipeline path module for the next path selection.
In one embodiment, the monitoring module can detect the temperature inside the cooling device in real time, and carry out analysis with the temperature data, and it distributes in which pipeline route to in the pipeline route module is arrived to temperature data transmission, thereby pipeline route module cooperation learning neuron can be effectual selects, thereby carries out preferred selection to those routes that the temperature is too high, the stability of assurance temperature that can imitate again.
In one embodiment, since the temperature cannot be guaranteed within a consistent, stable and unchangeable range in actual operation, fluctuation of the operating voltage occurs, and a large voltage drop occurs in severe cases, which results in insufficient power supply or excessive voltage, the voltage drop module is used for detecting the operating voltage at the moment, and when the voltage fluctuates greatly, cooling for accelerating or reducing the temperature is performed to achieve the effect of balancing,

the cooling system selects an optimal cooling path through the pipeline path module; and transmitting the control command to the cooling device;
