By analyzing the oilfield wireless monitoring system, the paper puts forward an oilfield monitoring system framework based on ZigBee wireless sensor networks on basic of studying ZigBee standard communication protocol. Software and hardware of data acquisition and transmission are designed in this system. The fast network and wireless transmission are realized.
In this paper, an analog digitalized AD method of small size was proposed, which based on low-power ARM, high-resolution, high accuracy, no delay in data output. Based on SOC technology, high-side detection technology and the processing theory of error data measurement, the AD technology replaced the way to conventional monitoring current signal by mutual inductor.
This paper puts forward a design scheme of remote terminal unit for oil-gas storage and transportation fields, adopts AT91SAM7X256 and DM9000A chip as the core hardware platform, accomplishs the Light Weight IP network protocol transplantation into the hardware platform, implements remote access and control functions from the host computer to the RTU through Internet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
