Research On Communication Protocols' Automatic Analysis Based On Compiler And Template

Communication protocol on transformer substation synthesis automation system safe and reliable operation plays an extremely important role, but as a result of a great variety of protocols, causes the numerous manufacturers' products not to be able the very good compatibility, causes the enormous difficulty for both sides. In order to change this kind of situation, IEC gradually put forward a series of technical standards for communication protocols. But because these series standards' formulation cycle is long, all aspects are not very balanced on this series standards' understanding and application situation, resulting in transformer substation synthesis automation system different manufacturers or same manufacturers in the different period on the same communication protocol to the realization differently, so that even if it is has been input products with same standard protocol, must revise the procedure for transformer substation system, which brings to the great inconvenience for on-site maintenance, and also waste a lot of manpower, material resources and financial resources.In view of the above situations, on the basis of various standards and pop protocols' reference, collection and collation, this thesis separately analyzes and summarizes questions when use same protocol and use different protocol, proposes communication protocol automatic parsing method based on the compiler and based on template. Then learn the CDT and the IEC60870-5-103 protocols by the numbers, and take these two kinds of protocols as the example, has designed and carried out two thoughts, and combining IEC60870-5-103 protocol applying for transformer substation synthesis automated software system, has implemented this idea, after the test, has a very good utility.For the first time, this thesis introduces thoughts based on the compiler and template into transformer substation synthesis automation system, facilitated the different equipments which use same standard protocol to turn on the transformer substation synthesis automation system, caused the on-site the maintenance and the debugging are easier, specially easy to revise and the expand based on compiler's procedure code.These two kinds of plan's proposition have certain theory and the practical significance to the transformer substation synthesis automation system's protocol automatic analysis.
