Development Of Quantitative Loading Monitoring Device Based On The ARM

With China’s sustained socio-economic development, the demand for oil isincreasing. Meanwhile, the existing quantitative loading level will affect theeconomic benefits. Therefore, it puts forward higher and higher demand for thedegree of automation of the oil depot, pay oil technology and productionequipment must meet the requirement of efficiency, accuracy, real-time capability,reliability.This article organically combines the micro-processing computer technology,automation control technology, crane arm tube loading technology andcommunication technology together to develop a set of monitoring device whichboth adapt to flammable and combustible environment and is able to solve thelarge flow and rapid quantitative loading. The exploitation of this device willsurely have a good social effect and objective economic benefits.The article on the basis of detailed analysis of the composition andcharacteristics of the major domestic quantitative loading system designs theoverall structure and the technological process of the ARM-based quantitativeloading monitoring device. The ARM-based quantitative loading monitoringdevice in this article to S3C2440A microprocessor as the core, which combinesloading units like mass flowmeter and electro-hydraulic valve to compose thefunctional modules that completes the hardware circuit design of each module（data acquisition module, display module and communication module） andinput-output interface.It support all kinds of communication interface for HARTprotool and Modbus protocol. In this paper, using the embedded Linux as theoperating system of the device to complete the construction of the cross-compilerenvironment and the transplantation of the embedded Linux system; Using Multi-stage electro-hydraulic valve to control the loading to achieve the purpose ofprevent water hammer and precise measurement. Using Qt Creator software to accomplish the pay-oil interface design.
