Abstract

The invention relates of an intelligent test system and a method used for IRIG (Inter-range Instrumentation Group)-B code fault-tolerant functions of a time synchronizer. The intelligent test system comprises a management machine and an IRIG-B code test device, wherein the managing machine is used for running test, analysis and management programs, and the IRIG-B code test device is connected with the management machine by a communication link to realize program control. The intelligent test system is characterized by being provided with an intelligent time frequency signal switcher, the program control of the management machine is realized by the test, analysis and management programs in the management machine, and the switching of the program control is carried out by the intelligent time frequency signal switcher. The intelligent test system is used for testing an IRIG-B code precision recognizing function, an IRIG-B code leap second processing function, and a IRIG-B code leap yearprocessing function. Under the condition of no manual intervention, the intelligent test system and the test method can easily and effectively carry out an intelligent test on the IRIG-B code fault-tolerant function and performance of the time synchronizer, and actually enhance the intelligent level of testing the complex functions and the performance of the time synchronizer. The test performance is accurate, the test efficiency is high, and the test time is greatly shortened.

Description

technical field [0001] The invention relates to time synchronization and time frequency testing, in particular to an intelligent testing system and method for IRIG-B code fault-tolerant function of time synchronization equipment. Background technique [0002] Existing time-frequency test equipment can only perform performance tests on a single time-frequency signal, and cannot perform comprehensive tests including signal redundancy tests on complex business performance and functions of time synchronization equipment. Inter Range Instrumentation Group (Inter Range Instrumentation Group, abbreviated as IRIG)-B time code (hereinafter referred to as IRIG-B code) error tolerance test is that the user sends the IRIG-B time code to the test analysis management software through the communication link to establish a communication connection. The test equipment assigns IRIG-B code fault-tolerant test tasks, and controls the IRIG-B code test equipment to output IRIG-B codes with differ...
