HOST: hybrid optoelectronic versatile telemetric system for local community

摘要

The work describes hybrid telemetric system built from cheap and standardized measurement stations equipped in cheap, off-shelf optoelectronic and classical sensors, provided with Internet connections and localized in local community administration and service centers. Cheap metrological server, for such a telemetric network, was designed. A number of such servers were manufactured and installed as a fully funtional network. The design included: functional structure of the server, measurements algorithms, software and hardware layers, in particular effective connections for large number of diversified sensors. The description presented below is devoted to a particular model of the network realized practically in a few local community sites around the city of Warsaw, including the Town of Zielonka and city center. The realized functional solutions for the hybrid optoelectronic network were debated in details. The debated system functionalities embrace three layers: functions, hardware and software, and include: choice of measured parameters, measurement methods, data acquisition, access to processed data via the Internet, kind of applied sensor and methods of sensor signal transmission, kinds of applied microprocessor chips, types of PC chips, functional structure, realized data, system programming environment, telecommunication and telemetric procedures, system test, etc. Usage of optoelectronics in the HOST system was emphasized.
