Satellite navigation system protocol test-oriented universal interface realization method

Abstract

The invention discloses a satellite navigation system protocol test-oriented universal interface realization method. The method comprises the following steps of: S1, hierarchically constructing an ICD structure template; S2, constructing a universal ICD input template on the basis of an object-oriented thought; S3, defining a frame structure format by adoption of a fragmented edition and assembly method; S4, carrying out classified management on the ICD templates on the basis of an XML file system so as to ensure that a classified management function for various ICD templates can be completed through an interface design interface; and S5, establishing an ICD template programmable information interface component model, so as to realize automatic test of satellite navigation system protocol interfaces. The method has the advantages of being easy to popularize and use, high in automatic test efficiency and the like.

Description

technical field [0001] The present invention mainly relates to the field of satellite navigation systems, in particular to a general interface design method for satellite navigation system protocol testing, mainly for realizing the flexible design and management of information interface formats among satellite navigation sub-systems, and the automation of information interfaces Test technology, a generalized satellite navigation system information interface format design and implementation method is proposed. Background technique [0002] The information interface interaction in the satellite navigation system is realized strictly according to the interface control document (ICD, InterfaceControl Document). The ICD-based satellite navigation system interface design reduces a series of problems caused by interface inconsistencies, and has been widely used in the field of navigation at home and abroad. But at the same time, the ICD types of the satellite navigation system are...

Problems solved by technology

[0003] However, these ICDs are still recorded and stored in the form of traditional Word paper or electronic documents, which has caused inconvenience in development and application to a certain extent.

ICD designers need to spend a lot of energy to repeatedly define the existing ICD general format; at the same time, once the type of the information interface changes or the parameters change, it needs to be redesigned, and the flexibility is poor

It is time-consuming and troublesome for users to find the specific information nodes of the required 1CD

In addition, the current satellite navigation system interface test has a low degree of automation, and the interface format code is manually edited, resulting in a large workload, a high rate of false typing, and many problems such as inconsistency between design and test.
