【Abstract】 This paper whose object is daqing oil-field electric power system sets up an automatic reading meter system with the facts of electrical distribution in daqing. The main research work in this paper is as follows:’It analyses the actualities and the developing trend about measuring electric power, electrical distribution and automatic reading meter. It sets up an automatic reading meter system for daqing oil fields by the structural and distributing energy characteristics of daqing electric power system. Meanwhile, it principally studies the structural projects of the dispatching main station of electric system and the secondary station of 8th oil factory. So this system can be guaranteed to have Real-time, accurate, scientific flexible and advanced traits.The communication technology of electric automatic system is discussed. It principally studies the technology of organizing nets , the communication technology of low pressure electric line and the technology of spread spectrum communication. It gives the project that power line carrier and direct sequence spread spectrum communication are combined with automatic dial-up passing modems for daqing automatic reading meter system.For the sake of monitoring automatic reading system and the status of mouth system and manpower communication, it brings forward the design and practical projects of supervising models. The monitor of the router and main processes is fulfilled and guarantees the system’s stability.Finally, it studies the way of organizing nets for direct sequence spread spectrum communication and brings forward the method of measuring parameters. It analyzes the status of applying direct sequence spread spectrum communication in daqing automatic reading meter system.The result of this paper has already been applied for the electric power company in daqing petroleum management bureau.更多还原
