Design of safety performance detector for mine-used belt conveyer

For problems of single detecting type and limited abilities including data processing and complex function realization of existing safety performance detection instruments for mine-used belt conveyer, a safety performance detector for mine-used belt conveyer based on PXI bus was designed by use of LabVIEW virtual instrument technology. Sensors selection and distribution were expounded as well as parameters detecting principle including speed and start-up or braking acceleration of conveyer belt, power and rotation rate of motor, temperature, running environment, deflection of brake disc, clearance of brake shoe, pressure of hydraulic oil, etc. Software and hardware design schemes of the detector were also introduced. The test results show that the detector can detect main performance parameters of belt conveyer real-timely with high accuracy.
