Design And Implementation Of Multi-parameter Centralized Monitoring System For Mine Exploration And Drilling

The data of mine exploration borehole is closely related to geological safety and green development.At present,water inrush disasters,hardening of mineral water,and complicated hydrogeological conditions in mining areas are inefficient to monitor multiparameter data through observation wells,and increasing the number of drilling wells will expand the cost,which is contrary to the spirit of green development.The anti-collision performance of LoRa communication generally decreases with the increase of network load.According to the above problem,this thesis completed the design and implementation of multi-parameter centralized monitoring system for mine exploration drilling,and proposed a low-power improved P-persistent CSMA anti-collision algorithm to improve network throughput under the condition of adapting to energy.The system can realize the collection,display and storage of multiple parameters in several monitoring areas,and the completed exploration boreholes can be landfilled,which reduces labor costs and damage to the environment.The multi-parameter centralized monitoring system of this thesis mainly includes information acquisition,wireless communication,information storage management and power supply.Information acquisition includes STM32 microprocessor,fiber grating sensor and fiber grating sensor analyzer.The sensor analyzer transforms the acquired optical signals to digital signals.STM32 microprocessor and sensor analyzer are connected through RS-485 bus to realize data communication according to serial Modbus communication protocol.Wireless communication includes LoRa transmission terminal,data transfer node and RS-485 serial bus.The wireless communication protocol is designed to ensure efficient communication of the system.Information storage management selects SD card to save on-site monitoring information in time,and uses SQLite database to save and manage drilling monitoring data.Based on QtDesigner and Pycharm development software combined with Python language to compile the upper computer software interface and functional interface,and SQL language is applied to viewing and displaying history Monitoring information.The power supply includes solar panels for photoelectric conversion,solar controllers for detecting and adjusting input and output,and batteries.The battery voltage data is transmitted to the STM32 microprocessor in real time via the RS-485 serial bus.The test results show that the multi-parameter centralized monitoring system for mine exploration and drilling has low power consumption,good reliability,convenient wireless network construction,and can realize 5 kilometers real-time communication.The use of low-power improved P-persistent CSMA anti-collision algorithm can improve the network throughput rate,there will be vast application prospects in the multiparameter centralized monitoring of boreholes.Figure[59]Table[17]Reference[79]...
