Abstract


With the rapid development of science and technology, more and more AutomaticMeteorological Station(Referred to as AMS) equipment is being put into operational use,thus greatly improving the method of the meteorological department how to "CatchWind and Rain". As a kind of weather observation equipment, AMS, according to theverification regulation requirements must undergo regular inspection, to ensure the dataaccuracy. Automation verification system of AMS is designed to solve the regularverification requirements, and then can ensure the accuracy of value transfer ofmeteorological instrument.AMS automation calibration system design and implementation was studied in thisthesis, including the following main research results. First of all, the working principleof AMS and the meteorological instruments metric job requirement is studied. AMS is aset of sensor technology, computer and network communication technology in one ofthe electrical equipment, is also a kind of high-precision meteorological observationinstrument, so periodic verification is the meteorological observation instruments inlegal procedures and AMS has a corresponding verification regulation demand.Secondly, Secondly, to conduct hardware selection and identify the principles of designby a combination of the AMS work principles and Verification Regulation requirements,the method of automation verification have be put forward from the test environmentcontrol, standard options, standard device and sensor automation verification approachfor temperature, humidity and pressure elements. Third, the key technology of softwaredesign using object-oriented programming language and relational databaseenvironment, of verification regulations require the collection of information and theautomation of the verification data by the control hardware have be studied in the thesis.In addition, by the system functionality and performance testing, we know theconclusion which automation verification system have be applied in the ordinary courseprofessional work successfully.Study how to optimize the completed AMS automation verification system designbased on artificial neural network mode. Based on the BP neural network PID control automation verification process, system control performance is more stable and controlaccurate more higher, so it can meet the needs of the verification process automaticcontrol functions better.AMS automation calibration system design, fully meet the AMS automationverification work demand, the system has been into formal operation in meteorologicaloperations. It guarantee that the various elements in the meteorological observationaccuracy, and greatly reduce the labor intensity of workers in the verification.
