Research on the oil temperature and level measuring and monitoring technology for distributed oil tanks

摘要

In order to meet the needs of testing and monitoring large-scale oil tanks, this paper designs real-time distributing measurement and monitoring system based on field bus. The system uses optical fiber sensor to collect the oil tanks' data with the advantages of the high precision, the high reliability, the strong anti-disturbed, and the avoiding of fire hidden trouble effectively. The system adopts industrial Ethernet to achieve long-distance communication by RS-485, and has a computer as controlling center to collect the data, and measures, monitors and manages oil tanks intelligently. For the characteristic of HART port protocol, the system is designed as real-time testing and monitoring software to predict and manage automatically with advantages of fault diagnosis, routine maintenance, prediction of fire hidden trouble, and function of reliability, relieving workload and good economical and social benefit.
