Abstract

The invention provides a high-availability servo system of an all-weather unattended measurement and control station, which comprises a servo control module for providing continuous pointing control on a satellite communication antenna, and an application module for a user to remotely or locally check the running state of the servo system, wherein the redundancy control module is used for providing a route requested by an application module between a main machine and a standby machine, the redundancy control module is used for redundancy control, the interface application interface module is used for providing an interface corresponding to the application module, and the equipment interface module is used for providing an interface of the servo system and hardware. According to the invention, a software hierarchical design form is adopted to reduce coupling between functions and enhance software expansion capability, a redundancy design of multi-machine hot backup is adopted to enhanceavailability of equipment, software availability is improved by adopting software startup self-starting, daemon process, process monitoring and the like, and a core module does not contain a graphical user interface. Single-machine-level separation of the graphical user interface and the core function is achieved, and the reliability of the core module is improved.

Description

Technical field[0001]The present invention relates to the field of program control, and more particularly to a high-availability servo system for all-weather unattended devices.Background technique[0002]The Weitong Antenna Servo System Software is an important part of the measurement and control system. After the target enters the antenna, the control antenna captures the target, and continuously track the target with a certain tracking accuracy, thereby receiving the goal of reliable gain. Signal work. If the servo system software is interrupted, the antenna will not be able to correctly point to the target, and cannot receive the target signal, resulting in the operation of the entire test station.[0003]It is mainly three major characteristics for servo system software all-day unattended. First, the software requires 24 * 7 All-weather uninterrupted providing the point-to-pending control service for the Wei News, otherwise it will lead to unavailability of the entire measurement a...
