A method for detecting coal flow on a belt conveyor based the two-dimensional laser is proposed in this paper to tackle complications of poor accuracy and real-time detection conveyor. This collects point cloud data surface lateral profile using two-position probe transmits with industrial Internet assure reliability transmission. The upper computer software system designed LabVIEW software. im...

Weight control system on the feeder conveyor determines the factor of the quality of products within an industry. The dynamics of the flow rate of material through the feeder conveyor weigh requires a good level of performance controllers. The base of current controllers such as FLC (Fuzzy Logic Controller) requires a certain amount of knowledge and expertise in its design that will make it dif...

This study was conducted with 90 poultry slaughterhouse workers, which perform the function of removing chicken parts from the conveyor belt, and sample was composed of 66 women (33.5 ± 6.5 years) and 24 men (35.7 ± 7.2 years), aiming to analyze the influence of anthropometry in the shoulder joint of these workers. Body discomfort was evaluated by a human body diagram, being applied at the end ...

The belt conveyor is the main transport equipments in coal field, and its controllable dirve system directly impacts on the running safety reliability and cost in coal production. Starting speed is unsmoothed in the traditional electrical drive system, which causes the belt off tracking or split and even safty accident. Therefore it is theory and practical significant to introduce a novel direc...

This paper presents a dual-mode modeling approach based on innovation design and engineering design, which is applied to the design of belt conveyor. Dual mode modeling method fusions innovation design pattern and engineering design mode, and realizes a combination of liberalization design and precision design, while the traditional parametric modeling is restricted by single thought, which exi...

A survey of the technical literature reveals that synthesis of Current Mode (CM) oscillators using single active building block (ABB) requires an additional identical or complementary current terminal to sense and take out the current output. The topologies of these oscillators are essentially based on the current mode approach. They use a Voltage Controlled Voltage Source (VCVS) and two curren...
