Abstract

The invention provides a ventilation resistance synchronous measurement system and method, the ventilation resistance synchronous measurement system comprises a synchronous measurement terminal system and a plurality of synchronous measurement subsystems, the synchronous measurement terminal system is used for calculating ventilation resistance and sending an instruction to the synchronous measurement subsystems; comprising a central data processing module, a data display operation module, a multi-mode wireless communication module and a power supply support module, and a synchronous measurement subsystem which is installed in a roadway and used for detecting roadway ventilation data and transmitting the data to a synchronous measurement terminal system, comprising a data preprocessing module, a detection control sub-module, a subsystem power supply support module, a subsystem multi-mode wireless communication module and an environment detection module, the system controls each measurement subsystem through a terminal system, underground ventilation data is automatically collected and measured, and the ventilation resistance of a mine can be accurately and rapidly obtained.

Description

technical field [0001] The invention belongs to the technical field of coal mine ventilation, in particular to a ventilation resistance synchronous measurement system and a measurement method for a coal mine ventilation system. Background technique [0002] The measurement of mine ventilation resistance is an important content in coal mine production, and its main purpose is to understand the operation status of the mine ventilation system and whether the mine ventilation fan is in an economical operation state. Coal mines must carry out ventilation resistance measurement every once in a while, because the ventilation network changes during the coal mine production process. Through the measurement of ventilation resistance, the overall and local operation of the ventilation system can be understood, and the air leakage of the mine ventilation system can also be guided. Because the operation state of the ventilation system is related to the safety of coal mine production, it...
