Intelligent sensor and mining belt conveyor transmission system health state monitoring method

Abstract

The invention discloses an intelligent sensor and a mining belt conveyor transmission system health state monitoring method, and belongs to the technical field of belt conveyor monitoring. Firstly, an intelligent sensor is provided, an intelligent algorithm is written for a main control chip in the sensor, so that the intelligent sensor has edge computing capacity and an abnormal state self-checking function, and a data acquisition mode is intelligentized through wireless data transmission; fourier transform is carried out on abnormal data collected by an intelligent sensor to extract frequency spectrum features, then the development trend of abnormal parts is given in combination with a pre-constructed recognition feature library, the current health condition of a transmission system is given through a health index evaluation formula, and then intelligent and wireless real-time monitoring of the belt conveyor for the coal mine is achieved; and compared with the prior art, the method provided by the invention is more intelligent, needs fewer computing resources, is more targeted to maintain, and saves labor cost.

Description

technical field [0001] The invention discloses an intelligent sensor and a method for monitoring the health state of a belt conveyor transmission system for mines, belonging to the technical field of intelligent sensors and a method for monitoring the health state of a belt conveyor transmission system for mines. Background technique [0002] With the continuous advancement of the construction of "smart mines", the intelligence of underground mining and transportation equipment in coal mines continues to increase. Enterprises have higher and higher requirements for operating parameter collection methods and state monitoring technology for underground coal mine equipment. Coal mine belt conveyors are used as The core equipment carrying the function of conveying coal, its stable, safe and efficient operation directly affects the production efficiency of coal mining enterprises, and the transmission system is the core component of the mining belt conveyor, which consists of a dr...

Problems solved by technology

[0004] At this stage, there is a health alarm system for belt conveyors used in coal mines, such as the invention of patent No. CN209554214U, which proposes a belt conveyor monitoring method with multiple monitoring substations. The complexity of the wiring around the machine increases the cost of data calculation, which does not meet the requirements of intelligence; although the invention patent with the patent number CN104635629A uses a sensor based on wireless technology, it only replaces the cable with wireless for simple data transmission. Can realize the intelligence of the sensor

In addition, the elevator health monitoring system and monitoring method based on the Internet of Things proposed by the patent No. CN104773625A also uses wired connection and centralized data processing, which will generate a large amount of redundant data and is not smart enough
