Detailed Description
The present invention is described in further detail below with reference to specific embodiments and the attached drawings. It is intended that the present invention not be limited to the particular embodiments disclosed, but that the present invention be limited only by the appended claims.
Referring to fig. 2, an embodiment of the present invention provides a method for equivalently simplifying a ventilation network, including:
step S001, a ventilation network is obtained, wherein the ventilation network comprises an air duct and air duct nodes;
step S002, detecting the wind resistance of the wind channel, if finding the wind channel which can not detect the wind resistance, extending towards the two ends of the wind channel which can not detect the wind resistance by taking the wind channel as the center, and determining a starting node and a final node of a minimum range which surrounds the wind channel which can not detect the wind resistance;
and S003, simplifying the air duct between the starting point and the final point according to the wind resistance equivalent principle.
The ventilation network is a system for ventilation under a mine, and in step S001, the ventilation network is obtained by actually detecting an air duct under the mine. The air channel in the ventilation network is a ventilation air channel, the air channel node is the joint of the two air channels, the two endpoints of the air channel are divided into a starting point and an end point according to the direction of the wind flow, and the network formed by the air channels from left to right according to the direction of the wind flow is the ventilation network.
In step S002, the wind resistance of the wind channel is detected, the wind resistance of the wind channel can be measured by a wind resistance instrument, and when a wind channel that cannot measure the wind resistance is found, it is described that the wind channel at this position needs to be simplified, and then the wind channel that cannot measure the wind resistance is taken as the center and extended to the two ends of the wind channel, so as to determine the starting node and the final node of the minimum range that the wind channel is surrounded. Taking fig. 3 as an example for explanation, in the ventilation network of fig. 3, the air duct (r) - (c) is an air duct that cannot obtain wind resistance, and at this time, the minimum range enclosing the air duct is (r) - (c) according to the extension of the air duct (r) - (c) to the two ends of the air duct, and the starting node and the final node of the minimum range are (c) and (c). R in fig. 3 represents wind resistance.
Optionally, a plurality of air ducts which cannot measure the wind resistance can be simultaneously selected to surround the minimum range, such as the air duct r-c, the air duct c-c and the air duct c-c, which cannot measure the specific wind resistance, so that the minimum range for surrounding the three air ducts is found to be the range of (c) -w-c, and the starting node and the final node of the minimum range are (c) and (c).
Optionally, when measuring the wind resistance of the wind channel, the wind channel capable of acquiring the wind resistance can be identified, and the wind channel incapable of measuring the wind resistance can be conveniently recorded by identifying the wind channel.
In step S003, the air duct between the start node and the end node is simplified according to the wind resistance equivalence principle. When a ventilation network needing to be simplified is found, the ventilation network needing to be simplified needs to be simplified according to the principle of equivalent wind resistance, and generally, the ventilation network can be simplified by fitting the air duct nodes.
In the embodiment of the invention, the ventilation network is simplified by a mode of finding the starting node and the final node which surround the air passage with the minimum range in the complex ventilation network, which can not measure the wind resistance, so that the problem that the complex ventilation network comprising a plurality of air inlet nodes, a plurality of air outlet nodes and a plurality of ventilation nodes and air passages inside the complex ventilation network can not be simplified in the prior art is solved, and the complex ventilation network can be correctly simplified.

And finding the air duct incapable of detecting the wind resistance, and deleting the redundant air duct if the air duct incapable of detecting the wind resistance is judged to be the redundant air duct. And the redundant air channel is deleted, so that the subsequent simplification process is more convenient.
And S404, extending the rest air channels which cannot detect the wind resistance to the two ends of the air channels which cannot detect the wind resistance by taking the air channels which cannot detect the wind resistance as the center, and determining a starting node and a final node of a minimum range which surrounds the air channels which cannot detect the wind resistance.
Step S405, before fitting and simplifying the air duct between the start node and the end node according to the wind resistance equivalence principle, further includes: and finding more than two air inlet nodes connected with the initial node and more than two air outlet nodes connected with the final node.
Step S406, simplifying the air duct between the start node and the end node according to the wind resistance equivalence principle includes:
and calculating the wind resistance of the air duct between the starting node and the ending node, fitting the starting node and the ending node into an intermediate air duct node, and distributing the wind resistance to the air duct between the intermediate air duct node and the air outlet node to obtain the simplified ventilation network.
Step S407, the method further includes: and verifying whether the simplified ventilation network is correct or not by calculating the wind resistance, the wind pressure or the wind volume of the ventilation network.
The following examples are given.
