BSS with Heterogeneous Ethernet SourcesNowadays, Telemetry Ground Station over a Range are all connected through Ethernet. Telemetry data can be dispatched from that layer to the Main Control Room. Nevertheless, Ethernet Protocols are so opened that the data transmitted can be heterogeneous (Throughput Ch10, Unpacked /Packed Synchronized data, PCM over Ethernet…). This paper describes an architecture based on a three layers software (Proprietary Layer, Software Frame Sync, and BSS) to manage BSS with these heterogeneous Ethernet sources. The assets (Test Range flexibility, low cost, easy upgrade) & the backwards (Encrypted data mismatch) with practical cases are also described.
BUILDING A FULLY CUSTOMIZABLE WINDOWS C# SOFTWARE CLIENT TO DISPLAY TELEMETRY FROM A REAL-TIME SOFT DECOM AND DISTRIBUTION SERVEROnce the telemetry is de-commutated by the real-time Soft Decom and Distribution Server, it will need a client to display the engineered values in real-time. To display the engineered values, the Client must connect to the real-time Soft Decom and Distribution Server using the Server’s message based subscription process. In addition, to be fully customizable, the Client needs to allow the user to select specific telemetry parameters and build displays to view the parameters. The RttmClient is a fully customizable real-time Windows client built using C#, Windows Presentation Foundation (WPF), Telerik Controls for WPF and NetMQ (C# lightweight messaging library). It is capable of displaying hundreds of real-time parameters in several displays. The parameters are displayed using different controls (widgets) including Numeric, Indicator (light), Gauge, Strip Chart, Table, Container and Text.
COMMON DATA PROCESSING APPLICATIONS ACROSS DECOMMUTATION VENDORSTraditional Decom Systems usually require vendor specific data descriptions and provide vendor specific processing capabilities. Using a Software Decom allows the Decom hardware to be setup with a minimal configuration. The added capability of a UDP Multicast over Ethernet for the framed decommutated data allows for common Applications to perform the heavy lifting of Archiving, Real Time Display, and Distributed Processing. Any PC listening on the Local Area Network can access the telemetry data in real-time. This allows common real-time displays, archival tools and data forwarding applications to all run simultaneously.
WIRING HARNESS CONSTRUCTION AND DATA PROTOCOL SELECTION FOR HIGH NOISE APPLICATIONSThe main problem with wired data transmission is exposure to electrical noise. In environments with extremely high noise levels, special care needs to be taken in order to accurately send data between two or more devices. In the case of motorsports, extreme noise on any critical data lines can cause engine failure, putting the driver’s safety at risk. The purpose of this paper is to explain effective construction techniques for noise reduction in a wiring harness, as well as to review how certain serial data protocols will handle errors in harsh conditions.
