Abstract


Depot surveillance systems typically use analog control panel constituted by a variety of switches, lights and indicating instrument monitoring . This way is entirely manual , there are monitoring function of a single , small amount of information , a large amount of manual meter reading , statistical calculations , and prone to error , analog hardware control panel monitoring equipment must be replaced when the oil depot expansion . To solve these problems , this paper proposes a configuration software and PLC the oil depots monitoring system based KingView design ideas and the implementation of the program . System combined with PLC technology , database technology and configuration software technology used on the , lower machine control mode , the host computer IPC configuration software , the next bit machine using the Mitsubishi Q series PLC , give full play to their respective advantages , to achieve a fuel depot hair oil job automatic monitoring. For oil volume susceptible to ambient temperature , leading to the decline of the LTC volumetric flowmeter accuracy , oil volume temperature error compensation method based on BP neural network , using the Levenberg-Marquardt algorithm for training good nonlinear mapping ability of neural network , according to the actual operating parameters of the training network , the algorithm implemented in the PLC to improve the the oil depot production measurement accuracy and production efficiency , intelligent oil flow error compensation . Analysis of the causes and the effects of water hammer control process control flow multistage off hair oil , a good solution to improve the efficiency of the hair oil with anti- water hammer \The lag caused due to the mechanical action of the oil flow inertia and valves overshoot will directly affect the precision of the hair oil . In the study on the basis of the precision control of hair oil , used to automatically adjust based on the amount of traffic overshoot law, and given a specific calculation method implemented in the PLC program to improve adaptive capacity and the precision of the hair oil purposes.
