Abstract:

To design intelligent equipment with a highly reliable mission to the utmost extent, the modular data construction approach under the guidance of the redundant hot backup concept was adopted, and a highly reliable launch control data processing equipment in a fully localized state was designed. The function modules were constructed through embedded software and hardware co-programming to ensure that the dual host could satisfy the requirements of external redundant communication in various bus forms. In the implementation of the internal control logic, the fault monitoring logic and information interaction process were integrated into the launch control software, and a triple heartbeat detection mechanism based on remote identification together with a task-based data synchronization method were adopted to realize the active/standby switchover, ensuring the stability and reliability of the switchover process to the greatest extent. To further explore the parameter characteristics and functional features of the launch control data processing equipment, copy verification, fault simulation and reliability modeling were performed to calculate the reliability index of the equipment. The test results indicate that the highly reliable launch control data processing equipment based on dual-host redundancy can achieve fault monitoring and real-time sharing of core data between the primary and secondary hosts, and guarantee the continued execution of launch tasks after a single host failure. The task reliability is improved by 23.6% compared to a single host.

Key words: dual host, redundant hot backup, modularity, remote identification, heartbeat monitoring, high reliability
