This paper presents the development of an automatic control of retardant system and parking of wagons, where after unloading in the car dumper, passing through retarders and switches and crossings. The retarder system is a device installed on the rails, at the end of the ramp and is responsible for braking the wagons. Automatic control of braking and objectively determine the optimal speed to ensure...
The TCP/IP suite protocol is one of the most widespread protocols groups for communication at long, average and short distances involving computer systems. Then, for trying the industrial networks standardization, for some years, it was also implemented in the industrial environment. The manuscript aims to propose a new way to accomplish the fieldbus modules control, using a flexible distributed architecture...
Model-Based Development is a design methodology used for automotive embedded software, where the engineering process involving OEM and suppliers can bring benefits providing an efficient exchange of information, workflow and tool chain adequately and standardized. Despite, with the growing demand for new functions for next generation of vehicles, we encounter with a complex system that yet require...
Inductive sensors are devices used widely in industry machinery and equipment and also the automation of industrial processes. With the advancement of technology type inductors built with planar microstrip or striplines, new devices have emerged as an inductor resonant element that does not require a ferrite, which was part of this hitherto fundamental for the construction of an inductive sensor....
This paper presents a computer tool to support in the project and development of an industrial Ethernet network, verifying the physical layer (cables–resistance and capacitance, scan time, network power supply–POE’s concept ”Power Over Ethernet” and wireless), and occupation rate (amount of information transmitted to the network versus the controller network scan time). These functions are accomplished...
