Electric shovel tooth wireless monitoring and alarm system and method based on weak magnetic field detection

Abstract

The invention provides an electric shovel tooth wireless monitoring and warning system based on low-intensity magnetic field detection. The electric shovel tooth wireless monitoring and warning system based on low-intensity magnetic field detection comprises low-intensity magnetic electric shove teeth, sensor modules and a monitoring and warning module. The sensor modules are arranged on a connection arm located between a steel wire rope on the lower side of a head sheave of a shovel and a bucket. The monitoring and warning module is arranged in a cab of the shovel. Each sensor module comprises a low-intensity magnetic field detection sensor, a signal amplifier, an A / D converter, a microprocessor and a wireless transmitter, wherein the low-intensity magnetic field detection sensor, the signal amplifier, the A / D converter, the microprocessor and the wireless transmitter are sequentially connected. The monitoring and warning module comprises a wireless receiver, a main controller and a warning module, wherein the wireless receiver, the main controller and the warning module are sequentially connected. The electric shovel tooth wireless monitoring and warning system and method based on low-intensity magnetic field detection can achieve real-time accurate and intelligent monitoring of the current work state of the shovel teeth, an alarm is given out when work is abnormal, the low-intensity magnetic signals are not influenced by the external environment, and the sensors are arranged on the connection arm between the steel wire rope on the lower side of the head sheave of the shovel and the bucket and are not prone to damage under the severe conditions of a mine.

Description

technical field [0001] The invention belongs to the field of electric shovel teeth monitoring, and in particular relates to a wireless monitoring and alarm system and method for electric shovel teeth based on weak magnetic field detection. Background technique [0002] During the working process of the mining electric shovel, the breakage and loss of the shovel teeth often occur. The ore is transported to the dressing plant, resulting in mechanical damage to the crusher of the dressing plant, causing huge losses and seriously affecting the normal operation of the mine. [0003] In order to solve the above problems, mines in my country basically use visual inspection, camera monitoring or laser scanning to detect the shovel teeth of electric shovels. Visual inspection and camera imaging detection have the disadvantages of distracting the driver's attention, and the optical instruments are easily damaged under the harsh conditions of the mine. CN201410229358.1 proposes a det...
