This invention discloses a method and system for parsing and verifying multi-format documents. The method includes: receiving a document to be parsed and generating a source file artifact record; identifying the document type and determining a standardized PDF file, performing validity verification, and generating a standardized PDF artifact record for association; submitting a parsing request using the standardized PDF as unified input, recording the request artifact, and receiving an external task identifier; obtaining the parsing result based on the task identifier and generating a parsing result artifact record, establishing a multi-dimensional association between the result and the source file, PDF, and request record; recording the task's lifecycle events and performing phased verification; and forming a document parsing artifact chain based on the artifact records and lifecycle events at each stage. This invention, by establishing a unified visual benchmark and a mesh-like link association, significantly improves parsing accuracy while achieving precise anomaly localization and data closed-loop auditing throughout the entire lifecycle.

The application provides a kind of distribution terminal single-phase ground fault research and judgment capability test method and system based on true type test platform, builds encrypted wireless communication environment and terminal hardware detection system, constructs the true type test field of adjustable network frame and grounding mode and selects overhead-cable hybrid test line;In the middle section, end and overhead-cable transition node of line, set up collaborative fault point, trigger multiple types of single-phase ground fault through fault simulation device, after collecting terminal response data, by master station according to the quantitative evaluation of differentiated scoring and multidimensional ranking rule realizes the quantitative evaluation of research and judgment capability.The application also constructs the test system containing six functional units, realizes the systematic and standardized test of distribution terminal single-phase ground fault research and judgment performance under highly realistic environment, solves the problems that traditional test and field working condition are disconnected, single in assessment dimension and lack of objectivity in evaluation, provides reliable basis for equipment selection, algorithm optimization and distribution network fault handling capability improvement.

The application relates to the technical field of IP packet analysis and monitoring, in particular to a header route analysis and real-time monitoring system and method in network IP packet transmission. The technical problems to be solved are low header analysis efficiency, poor compatibility, insufficient real-time monitoring capability and non-closed-loop monitoring link in the prior art. The technical solution points are as follows: collecting original IP packet data in a network; performing pretreatment operation on the original IP packet data; identifying the type of the current message and extracting the key field of the header; performing source / destination address format conversion on the key fields extracted from IPv4, IPv6 and IPv9 headers; judging whether the transmission network scene of the current IP packet is a normal scene or a complex scene; based on the converted data of the IPv4, IPv6 and IPv9 headers, performing analysis respectively according to different scenes; performing real-time detection on the IP packet to obtain an abnormal detection value; setting an abnormal level to obtain an abnormal result.
