Embedded Systems In The Tt & C Ground Station Terminal Equipment

With the development of electronical technology,The speed of the BBE(base-band equipment) and the precision of the data is increasing, especially(real time, reliability,configure,transplant and so on) are requested rigor. The base-band equipment need accommodate the various demands of application,and quicken to open up the periods of the syetem, reduce the cost of the system.The subject of this application is in this context, WindRiver VxWorks,BMC and data processing software are two fittings of the baseband subsystem. They mainly carry out device monitoring and working parameter control, process the command data, telemetry data, ranging data, and velocity data, and also exchange information with peripheral equipments very quickly. BMC sets the working parameters to all device units, configures devices, and monitors the operating status of devices and reports the subsystem device states to BMCThe base-band equipment mainly contains a integrated displays,a industrial computer,CPCI cards and driver and its software(application-embedded, application-windows).In this context introduction the working principle of base-band equipment, application-windows development is using VS2005, application-embedded development is using Wind River Workbench, Especially we introduced the software usage of BBE and development process.
