Embodiment Construction
[0023] Such as figure 1 shown. Mine shaft safety improvement detection method based on firefly algorithm, based on remote monitoring technology, using multi-channel temperature sensor 1 and multi-channel pressure sensor 2 to measure the temperature and pressure of the area to be detected, and using a single bus to transmit temperature and pressure signals to the monitoring RTU 6 of the instrument, and after being processed by the RTU 6 of the monitoring instrument, the RS485 bus is used to convert the RS232 signal that can be recognized on the PC through the RS232 / RS485 bus converter, and then sent to the firefly algorithm model of the built-in software of the upper computer through the RS232 bus. To obtain a more accurate early warning of future development trends, and display the data on the host computer 3 in real time, including the following steps:
[0024] (1) According to the specific conditions of the mine to be detected, several detection planes are set up, and multi...

The invention discloses a method for improving and detecting the safety of a mine shaft on the basis of a firefly algorithm. The method includes drilling holes at different positions of various planes of a mine shaft wall, burying temperature sensors and pressure sensors in the holes according to the special structure of the mine shaft wall and monitoring the temperature and the pressure of the mine shaft wall in real time; transmitting data acquired by the various temperature sensors and the pressure sensors which are hung on a single-bus cable in a single-bus mode to a monitoring instrument RTU (remote terminal unit); displaying the data on a liquid crystal display after the monitoring instrument RTU receives the data, converting the data into RS485 data and transmitting the RS485 data to an RS232 / RS485 bus converter; transmitting the data to a PC (personal computer); further transmitting the data to kingview software of an upper computer and transmitting the data to a firefly algorithm model of MATLAB software; and acquiring accurate future safety trend of the mine shaft wall by means of calculation. The method has the advantages that the temperature and the pressure of the shaft wall are predicted by the aid of the advanced firefly algorithm, and the prediction quickness and accuracy are greatly improved.
Description
technical field [0001] The invention relates to the field of mine shaft safety lifting detection methods, in particular to a mine shaft safety lifting detection method based on a firefly algorithm. Background technique [0002] With the gradual development of my country's economy, coal mining technology is gradually developing in the direction of high yield and high efficiency. However, according to the monitoring results of the mining group on the deformation of the shaft wall and the change of the "four containment" water level, it shows that as the aquifer (bottom containment) drains and the formation is consolidated and compressed, the formation exerts a vertical negative frictional resistance on the shaft , when the negative frictional resistance accumulates to a certain value, a weak part in the borehole wall will experience vertical compression damage; due to the unevenness of the formation and its stress, there will be differential settlement of the well tower founda...
