| With the rapid development of the economy,the demand for oil and natural gas in China has increased rapidly,so the security and protection of oil pipeline has become a hot topic.At the same time,the traditional manual patrolling security measures in the warehouse and the airport will save a lot of manpower,material resources and low efficiency.It is therefore urgently needed to automate a long distance and wide range of security solutions.Therefore,this paper puts forward the optical fiber early warning system.The system can solve these problems very well.The fiber optic warning system mainly includes two aspects:alarm signal detection and recognition.This paper focuses on the design and implementation of alarm signal type recognition,extraction is proposed by duty ratio signal,vibration signal average amplitude difference over the mean rate and other parameters were used to identify detected,can be achieved on the walk,a car,the type recognition of mechanical signal,in order to inform the operator of different types of alarm properly processing.Secondly,based on the identification of the type,the software design of a intelligent early warning system can meet the detection and identification results,detection and identification of alarm data,then the data processing,storage,and finally displayed on the visual interface,so that the personnel on duty to take measures to alarm.According to the function,the intelligent early warning system is divided into the server and DSP interaction modules,the server client interaction module,the business function module and the algorithm module.Then introduces the design and Realization of server software module,system testing and system function and performance of the software on the basis of function realization,finally puts forward the business logic,data structure,database optimization strategy and so on,in order to save the system resources,improve the operational efficiency of the program. |
