Power pre-measurement and control equipment power relay cabinet modular redundant control system

Abstract

A dynamic-pre-positioned measurement and control equipment dynamic relay cabinet modularized redundancy control system is provided. The dynamic-pre-positioned measurement and control equipment dynamic relay cabinet modularized redundancy control system includes a power source control module, a ground core one-stage gas distribution station control module, a ground core two-stage gas distribution station control module, a rocket engine valve control module and a wired measurement parameter acquisition display module; according to the power source module, master and slave power source hot standby redundancy control is adopted; and according to control signals of a dynamic relay cabinet, redundancy control of double-component synchronous electrification is adopted. According to the dynamic-pre-positioned measurement and control equipment dynamic relay cabinet modularized redundancy control system of the invention, a small number of functional modules are adopted to form control units as much as possible, and therefore, the dynamic-pre-positioned measurement and control equipment dynamic relay cabinet modularized redundancy control system is stable in performance and simple in structure; the modules are provided with standard interfaces, the combination of different functional modules and the interchange of identical functional modules can be ensured, and therefore, supporting facilities of an overall unit can be simplified, and through different combination and expansion, requirements of launch of rockets in various models can be satisfied, and an ability to fast respond to faults appearing before the launch can be improved. The dynamic-pre-positioned measurement and control equipment dynamic relay cabinet modularized redundancy control system can be applied to dynamic-pre-positioned equipment or other single-unit products and can satisfy requirements of zero-window launch missions of the rockets.

Description

technical field [0001] The invention relates to a control system for measurement and control equipment, in particular to a modular redundant control system for power relay cabinets of power front measurement and control equipment. Background technique [0002] The pre-power measurement and control equipment is the supporting equipment for the power measurement and control system of the rocket launch site. Focus on all the control work in the stage, so the power front-end measurement and control equipment is required to have high reliability. If there is a failure in the pre-shooting process stage, it has the ability to quickly replace the response. The previous supporting front-end control equipment has shortcomings in the actual use process: First, the degree of integration is low, and the combination and interchangeability of each control module are poor, resulting in complicated cabinet configuration and state transition, and a long time to replace spare parts; second, al...

[0002] The pre-power measurement and control equipment is the supporting equipment for the power measurement and control system of the rocket launch site. Focus on all the control work in the stage, so the power front-end measurement and control equipment is required to have high reliability. If there is a failure in the pre-shooting process stage, it has the ability to quickly replace the response. The previous supporting front-end control equipment has shortcomings in the actual use process: First, the degree of integration is low, and the combination and interchangeability of each control module are poor, resulting in complicated cabinet configuration and state transition, and a long time to replace spare parts; second, all control signals are controlled by unit devices. , it is difficult to meet the requirements of the "zero window" launch mission
