Abstract

A device and method for monitoring the running speed of a belt based on the photoelectric effect. The device: a reflective strip is set on the non-bearing surface of the belt to be monitored; Drive circuit, microprocessor, shaping circuit, photoelectric detection circuit, photosensitive element, receiving lens, attenuation sheet, interface module, communication module, display and alarm module. Method: set a reflective stripe belt on the non-bearing surface of the belt to be monitored; arrange a monitoring unit at the position facing the non-bearing surface of the belt to be monitored; emit light of a certain wavelength to the surface of the reflective stripe belt by the emitting light source; receive the light from the receiving lens The light is reflected, and the pulse signal is formed by the photosensitive element, the photoelectric detection circuit and the shaping circuit and sent to the microprocessor, and the microprocessor processes the pulse signal to obtain the instantaneous speed of the belt to be monitored. The device and method can realize non-contact monitoring.

Description

technical field [0001] The invention relates to the technical field of speed monitoring of belt conveyors, in particular to a device and a test method for testing the stable bearing capacity of angle steel crossed oblique members. Background technique [0002] Belt conveyors are widely used in ports, metallurgy, mining and other industries. During the operation of the belt conveyor, the belt is prone to speed fluctuations, slipping and stalling. Excessive belt speed fluctuations will affect the stability of the belt conveyor operation. Belt slipping may lead to increased belt wear, which will shorten the service life of the belt. , and the belt stall may cause the belt conveyor to run out of control and reduce the accuracy of conveying. Therefore, the belt speed monitoring device is very important in the belt conveyor. [0003] In the prior art, a large number of contact speed detection systems based on photoelectric encoder discs often have mechanical moving parts. After w...
