Monitoring method and device

Abstract

The invention provides a monitoring method and device, and the method comprises the steps: acquiring real-time data; judging whether the data change meets a preset threshold value or not to obtain a judgment result; if the judgment result is yes, adjusting the mode to be enabled; nd carrying out the processing in the enabled adjustment mode: if the response time is exceeded, forbidding the adjustment mode. According to the invention, the sensor data can be automatically adjusted according to a set alarm threshold value, and a new way is provided for stabilizing sensor output and improving field adaptability. The field mutation data has a very good processing effect; according to the method, the response time of the sensor is not influenced, the output stability is improved, the response time of the sensor is not influenced, and the change trend of the sensor is not influenced.

Description

technical field [0001] The invention relates to a coal mine underground technology, in particular to a monitoring method and device. Background technique [0002] The safety monitoring system is a system that integrates monitoring and control. Monitoring is the foundation, control is the means, and safety is the purpose. There are many types of sensors in the coal mine environment, including: methane sensor, carbon monoxide sensor, oxygen sensor, carbon dioxide sensor, wind speed sensor, temperature sensor, pressure sensor, dust sensor, start-stop sensor and smoke sensor, etc. The environment of the coal mine is high temperature, high humidity and high dust, the electromagnetic environment is harsh, vibrations and falls occur from time to time, the blasting method is still in use, and the load capacity of the coal mine site is insufficient. Affected by the environment, the output data of the sensor will jitter abnormally. The second-level data jump of the sensor is the most...

AI Technical Summary

Problems solved by technology

The environment of the coal mine is high temperature, high humidity and high dust, the electromagnetic environment is harsh, vibrations and drops occur from time to time, the blasting method is still used, and the load capacity of the coal mine site is insufficient. Due to the influence of the environment, the output data of the sensor will jitter abnormally

The second-level data jump of the sensor is the most typical and difficult to deal with. If it exceeds the alarm point, an alarm will be issued, and if the power-off point is exceeded, the associated power will be cut off, resulting in abnormal events.
