Abstract

The invention discloses a belt conveyor speed detecting system based on radio-frequency identification. The belt conveyor speed detecting system comprises two or more radio-frequency identifying labels, a belt, two or more readers and a controller; the radio-frequency identifying labels are embedded on the belt; the belt moves along with a drum; the distance between every two readers is fixed; the readers identify the radio-frequency identifying labels, and send signals to the controller; and the controller calculates the operation speed of a belt conveyor according to identified label signals. The belt conveyor speed detecting system has the multiple beneficial effects of: fast label scanning speed; capability of penetrating through dust to read under bad field environments without being interfered by external; incapability of causing such mechanical damage as collision and wear under strong vibration environment; and incapability of influencing the label characteristics and the monitoring accuracy.

Description

technical field [0001] The invention relates to the field of belt conveyor speed detection, in particular to a belt conveyor speed detection system based on radio frequency identification. Background technique [0002] In production, it is usually necessary to measure and collect the speed of the belt conveyor as an important parameter and control basis for monitoring the operation of the belt conveyor. The belt conveyor uses a speed sensor to measure the speed. Compared with the set normal speed, if there is a slipping or overspeed fault, the belt conveyor is required to stop running after a delay. [0003] Due to the structural characteristics of the belt conveyor, the installation of testing equipment is affected by structural restrictions, and the on-site operating environment of the belt conveyor is harsh. The speed measurement methods and equipment used are often prone to problems such as large measurement errors, low precision, and easy wear and tear of equipment. Ho...
