Currently, this is generally achieved by power-splitting the high-quality signal output by the atomic clock. The entire system is complex, and if a backup is added, the entire system will be even larger.

[0051] The present application provides a highly reliable intelligent 100MHz frequency reference signal generation and distribution system design method. The basic principle of the method is: by studying the design method of a multi-channel high-precision, high-quality intelligent 100MHz frequency reference signal generation and distribution system, taking into account reliability and high isolation, based on the ASAAC module, a highly reliable intelligent 100MHz frequency reference signal generation and distribution system design is completed, such as Figure 2As shown, the whole system consists of two rubidium atomic clock modules, a frequency standard module and a reference power division module, and on this basis, a master-backup connection relationship is proposed. This application adopts an intelligent, standardized and modular design concept. It not only has the function of generating high-quality 100MHz frequency reference signals, but also has the function of distributing 100MHz frequency reference signals. It can eventually output 22 100MHz frequency reference signals with high isolation, high precision, high stability and low phase noise. This application realizes the intelligent fault detection and communication functions of the internal modules of the system by adding a control unit inside the first rubidium atomic clock device, the second rubidium atomic clock device, the frequency standard device and the reference power division device, and designs a built-in self-test system, thereby increasing the reliability of the entire system, and studying high-isolation power amplifier technology to achieve high isolation of the entire system. This application adopts a master-backup design method, with up to 8 types of master-backup working mode switching, which improves the reliability of the system, and the master-backup working mode switching is controlled by an external OC instruction. Each module adopts an LRMV connector, which not only realizes quick plug-in replacement, but also enhances maintainability.

The rubidium atomic clock device includes a first rubidium atomic clock device and a second rubidium atomic clock device, and the composition and function of the first rubidium atomic clock device and the second rubidium atomic clock device are exactly the same.

[0054] In the embodiment of the present application, each module is designed based on the European Joint Standard Avionics Architecture Committee (ASAAC) standard and has the ability to be quickly installed and replaced. In addition, the connection between each module and the rack is installed using LRMV connectors, which are convenient for quick plugging and unplugging and interface universalization. The LRMV connector is a hybrid connector for multiple signals such as RF, digital, optical and power.

[0055] The system adopts a master-backup design method, in which the first rubidium atomic clock module and the second rubidium atomic clock module are cold backups of each other, and the main functions of the frequency standard module and the reference power division module are designed with backup. The master-backup working mode of each module can be controlled by an external 0C command issued by the host computer system. Here, A1 can be used to represent the master of the first rubidium atomic clock module, A2 can be used to represent the backup of the first rubidium atomic clock module, B1 can be used to represent the master of the frequency standard module, B2 can be used to represent the backup of the frequency standard module, C1 can be used to represent the master of the reference power division module, and C2 can be used to represent the backup of the reference power division module.
