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.

Embodiment Construction

[0017] In order to understand the characteristics and technical content of the present invention in more detail, the implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the present invention.

[0018] figure 1 A schematic flow diagram of a monitoring method provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0019] Step S101, obtaining real-time data;

[0020] Step S102, judging whether the data change satisfies a preset threshold, and obtaining a judging result;

[0021] Step S103, if the judgment result is satisfied, the adjustment mode is enabled;

[0022] In step S104, the processing is performed in the enabled adjustment mode, and if the response time exceeds the response time, the adjustment mode is prohibited.

[0023] In another embodiment, before obtaining ...

Abstract

A monitoring method and device provided by the present invention obtains real-time data; judges whether the data change satisfies a preset threshold, and obtains a judgment result; if the judgment result is satisfied, the adjustment mode is enabled; Processing can be performed in the adjustment mode, and if the response time is exceeded, the adjustment mode is prohibited. According to the set alarm threshold, the sensor data can be automatically adjusted, which provides a new way to stabilize the sensor output and improve the site adaptability. The on-site mutation data has a good processing effect; this method does not affect the response time of the sensor, and while improving the output stability, it does not affect the response time of the sensor, nor does it affect the change trend of the sensor.

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...
