Abstract

The invention discloses a time reference redundancy signal intelligent testing system and method of a time synchronization device. The time reference redundancy signal intelligent testing system comprises a GPS / Beidou satellite antenna receiver, a manger for operating a testing and analyzing management program, a time frequency standard source connected with the manager through a communication link for realizing program control, and a time scale impulse testing device, and an IRIG-B (Inter-Range Instrumentation Group) code testing device. The time reference redundancy signal intelligent testing system is characterized by being provided with an intelligent time frequency signal switcher, the program control of the manager is realized through a testing and analyzing management program operating in the manager, program control switching is carried out by the intelligent time frequency signal switcher, and the intelligent time frequency signal switcher is used for testing the time reference redundancy signal switching function. Under the condition of no need of manual intervention, the function and the performance of outside reference signal switching of the time synchronization device are simply and effectively intelligently tested, the complex service function and the performance testing intelligent level of the time synchronization device are reliably improved, the performance is more accurately tested, the testing efficiency is higher, and the testing time is greatly shortened.

Description

technical field [0001] The invention relates to time synchronization and time frequency testing, in particular to a time synchronization equipment time reference redundant signal intelligent testing system and method. Background technique [0002] Existing time-frequency test equipment can only perform performance tests on a single time-frequency signal, and cannot perform comprehensive tests on complex business performance and functions of time synchronization equipment, including time reference redundant signal tests. The time reference redundant signal test is that the time synchronization equipment under test loses three kinds of external time reference redundant signals redundantly configured: Global Positioning System (Global Positioning System, abbreviated as GPS) time signal, Beidou time signal and international Inter Range Instrumentation Group (IRIG for short)-B time code (hereinafter referred to as IRIG-B code), for one of the three or for both GPS satellite signa...
