Currently device with microcontroller has been widely used in industrial field. However, a large number of devices don't have the network interface and the data from them can not be transmitted in network. A design of ARM processor-based embedded Ethernet interface is presented. In the design, an existing SPI serial device can be converted into a network interface peripheral to obtain compatibility...
Now international research on the intelligent uptown is in the ascendant, while domestic research has already implemented the construction of intelligent uptown. Field-bus technology is widely applied in the intelligent uptown, but it has not standard protocol and higher costs. With the development of embedded technology, embedded single chip controller of data acquisition and management system of...
In some oil fields, the consumption of electricity and energy was very high because the beam pumping unit worked sustained, expect in the height period of electricity consumption. It increases the burden on the grid and make machines wearied easily when voltage instability. In this paper, we propose a concept of intermittent pumping to beam pumping unit and build a monitoring system of oil wells based...
This paper investigates the use of Ethernet/IP communications protocol for data acquisition and control of electrical networks in an industrial environment. A high-speed communication connection among all the devices operating in a distribution network using breakers, contactors, relays, power meters and other devices may allow a large amount of data to be exchanged to and from an industrial/utilities...
