Belt conveying control system

Abstract

The invention discloses a belt conveying control system in the field of conveying devices. The belt conveying control system comprises a power frequency voltage reference unit and a signal setting unit which are connected to an industrial computer, wherein the industrial computer is connected with a PLC, an analog signal input end of the PLC is connected with a signal output end of a speed, material position and weight signal collecting unit, a digital signal input end of the PLC is connected with a signal output end of an overload and overcurrent signal collecting unit, an analog signal output end of the PLC is connected with a signal input end of a belt motor through an ABB frequency converter, a signal output end of the belt motor is connected with a conveying belt, a digital signal output end of the PLC is also connected with a signal input end of the ABB frequency converter, and a signal output end of the PLC is further connected with a signal input end of an alarming processing circuit. By means of real-time monitoring on the working state of the conveying belt, the belt conveying control system enables a conveying system to be simple in structure, easy and convenient to install and operate, low in breakdown rate and high in reliability, and can be applied to the belt conveying system.

Description

technical field [0001] The invention relates to a transport device, in particular to a belt transport device. Background technique [0002] Material conveying systems are widely used in product packaging, assembly line operations, testing and other related industries, but have high requirements on the accuracy, reliability and automation level of the system. Cement plants in the prior art generally transport cement to packaging warehouses or bulk warehouses through transport belts. The transmission belt adopts the material conveying control system controlled by traditional relays and contactors. Due to the large number of electrical components and scattered installation of this type of control system, the control system is complicated, the operation is difficult, and the installation and maintenance workload is large, and it is difficult to modify the control scheme. , thereby greatly affecting the production efficiency of the enterprise. In addition, due to the harsh envi...
