A mining vehicle weighing system and method based on fiber grating sensor

Abstract

The invention discloses a mining vehicle weighing system and a mining vehicle weighing method based on fiber bragg grating sensors. The mining vehicle weighing system comprises fiber bragg grating sensors, a fiber bragg grating demodulator, a micro-processing display and a background monitoring system, wherein the plurality of fiber bragg grating sensors are respectively arranged on a plurality ofstrain points of a bearing beam of a mining vehicle; the fiber bragg grating sensors are connected with the fiber bragg grating demodulator by means of armored optical cables; the fiber bragg gratingdemodulator is connected with the micro-processing display by means of a lead wire; the fiber bragg grating demodulator is used for resolving the change of the central wavelength of a fiber bragg grating and transmitting a data signal to the micro-processing display; the data signal received by the micro-processing display is subjected to algorithm processing to obtain mining vehicle load information, and the mining vehicle load information is transmitted to the background monitoring system; and the background monitoring system compares the mining vehicle load information with a mining vehicle reasonable load interval and transmits a data signal indicating overload or insufficient load of the mining vehicle to the micro-processing display.

Description

technical field [0001] The invention relates to the technical field of mining vehicle weighing, in particular to a mining vehicle weighing system and method based on an optical fiber grating sensor. Background technique [0002] In the process of mineral transportation, due to the complex geographical environment and changing road forms, trackless mine vehicles are often used for transportation. Mining vehicles often appear overloaded or unsatisfactory when transporting minerals. Overloading of mining vehicles will easily roll over, puncture tires and weaken the braking performance, which will lead to safety accidents. In addition, the unsatisfactory load of mining vehicles will affect the transportation efficiency of minerals and increase transportation costs. Therefore, it is particularly important to monitor and control the load of mining vehicles in real time to reduce the phenomenon of overloading or dissatisfaction of mining vehicles. [0003] With the development of...

Problems solved by technology

Traditional strain gauge sensors have problems such as weak output signal, poor anti-interference ability, and low measurement accuracy, while fiber grating sensors have the advantages of immunity to electromagnetic interference, light weight, small diameter, high sensitivity, and good stability. The passive characteristics of the grating have inherent advantages in the measurement environment of damp and highly dangerous gases in mines
