主机控制软件在测发控系统中的应用研究

主机控制软件是运载火箭一体化测发控系统的关键环节,测试流程可配置是主机控制软件的重要研究方向。针对现役CZ-2D、CZ-4B/C一体化测发控系统主机软件测试流程不可配置、软件代码更改频繁、升级次数多、管理成本高等问题,新一代主机控制软件以简易、可靠、快速可配置、界面友好为主要特征,通过采用“抽象一级基础文件、拼装二级测试文件、独立发送器接收器、网络协议映射”的软件架构开发策略,结合现役主机控制软件优点、新一代测发控软件系统要求、通信类型、接口定义等,实现了新一代可配置主机控制软件,为未来主机控制软件的研究打下了技术基础。     

Influence of the Transverse Field Component on the Edge Effect in a Short-Gap Discharge

In a general plane-parallel electrode system the edge of the electrode will undermine the uniformity of the dielectric barrier discharge （DBD） because of the influence of the distorted electrical field. In this paper, the influence of the non-uniform electrical field on the edge effect of DBDs in a short-gap is investigated. We present some o.f the experimental results of DBDs produced by three kinds of convex-spherical electrodes. The results show that there is a dark area （the homogeneous discharge） in the central region of the electrode and a bright halo （the filamentary discharge） in the outer peripheral region, and the radius of the dark region is determined by the electrode geometry. The calculated results of the transverse （radial） field component distribution on the surface of the electrodes show that the edge effect does not come from the electrode edge, but the transverse field. The discharge has enough space to be fully developed and then format the filamentary discharge in the outer peripheral region because the streamer of the filamentary discharge is driven to move along the direction of the longer path by the transverse field. Thus, the homogeneous discharge （the Townsend DBD or a glow DBD） could not be produced in this area.
