Abstract

The invention provides an intelligent time service management method for a complex system, and the method comprises the steps: respectively receiving time code information and a second pulse signal of an external timing system source through two interfaces to serve as an external time service signal, receiving a signal of an internal timing system source through the other interface, and enabling the time code information and the second pulse signal obtained through analysis to serve as an internal time service signal; and transmitting an external time service signal sent by the external timing system source and an internal time service signal sent by the internal timing system source to the FPGA for validity judgment to obtain a timing system source validity judgment result. The method can intelligently detect the validity of a plurality of timing system sources. According to the technical scheme of the embodiment of the invention, timing system source selection is carried out according to priorities; when the timing system source breaks down, switching of the timing system source can be intelligently carried out; high-precision time service and punctuality can be continuously carried out; accurate time service can be carried out on a plurality of external devices; the problem of high-precision time service and punctuality of a complex system when satellite signals are interfered or an external timing system source fails is solved.

Description

Technical field: [0001] The invention relates to but not limited to the technical field of embedded computer signal processing, in particular to an intelligent timing management method for complex systems. Background technique: [0002] In a complex training system that includes multiple devices with different functions, it is very important to ensure that all devices work under the same clock reference. For a high-precision complex training system, to ensure the accuracy and effectiveness of the cooperation of individual devices during system operation, as well as the authenticity of post-assessment and analysis, each device in the system must ensure clock synchronization, and a unified timing source must be used to Each device in the system performs time service. [0003] There are two sources of time statistics, one is to use a special external time system reference source equipment, and the other is to directly receive satellite navigation signals to obtain satellite ti...
