Abstract

The audio section has connections for microphone input, speaker output and call buttons, for use as a receiver. This enables network communication to one or more audio/video data boards (AVD) or to a central computer (server). A USB interface connection is provided, e.g. for cameras, permitting continuous image data transmission via the network cable connections or wireless LAN, to one or more network PCs. A biometric sensor may be connected to the USB input, similarly enabling transmission of fingerprints as coded data packets for storage in memory on individual network computers or a server.

Description

Mit dieser Erfindung wird vorgeschlagen ein Multifunktions-Board zu entwickeln welches Sprach-, Audio-, Video-, und Datenpakete so konvertieren kann, dass diese in einem Kommunikationsnetzwerk übertragen und verarbeitet werden können. Diese Daten sollen vorwiegend von einem (Server) oder mehreren Netzwerk PCs (Workstations) über dessen interne Konfiguration verarbeitet werden können. Mit dieser Entwicklung wird vorgeschlagen alle Kommunikationen über längere Entfernungen, explizit die Anbindung an die Zentrale (Server), ausschließlich über Ethernet auf der Basis TCP/IP (Internetprotokoll) zu realisieren, dass Board verfügt über eine Ethernet-Schnittstelle (1).With this invention it is proposed to develop a multifunction board which can convert voice, audio, video and data packets in such a way that they can be transmitted and processed in a communication network. This data should primarily be processed by one (server) or several network PCs (workstations) via its internal configuration. With this development it is proposed to realize all communications over longer distances, explicitly the connection to the central office (server), exclusively via Ethernet based on TCP / IP (Internet protocol), that the board has an Ethernet interface ( 1 ).

Mit dieser Entwicklung wird vorgeschlagen, dass ein Multifunktions-Board oder mehrere Boards als Endgeräte somit als Gegensprechstellen dienen, dass Board verfügt über einen Lautsprecheranschluss, einen Mikrofonanschluss und eine Ruftaste (1).With this development it is proposed that a multifunction board or several boards serve as end devices as intercoms, that the board has a loudspeaker connection, a microphone connection and a call button ( 1 ).

Mit dieser Erfindung wird vorgeschlagen, als Protokoll für die Audio Datenübertragung einen UDP-Stream im Wave oder PCM-Format oder einem aus der PC-Welt bekannten Format einzusetzen.With This invention is proposed as a protocol for audio data transfer a UDP stream in wave or PCM format or one from the PC world use known format.

Mit dieser Entwicklung wird vorgeschlagen, dass zur lokalen Erweiterung das Multifunktions-Board über zwei serielle Schnittstellen (RS 232), sowie über zwei USB-Ports verfügt (1). Alle Daten, die über diese Anschlüsse verfügbar sind, können prinzipiell über Ethernet weiter geleitet werden (z.B. an einen oder mehrere Zentralen bzw. Server). Mit dieser Entwicklung wird vorgeschlagen, die Anbindung der USB-Geräte insbesondere USB-Videokameras und Biometrischer Sensor an das Multifunktions-Board mittels Treiberimplementierung auf dem Mikrocontroller Des Multifunktions-Boards zu realisieren, welcher dann die Daten in einem Standardformat für eine oder mehrere Zentralen bereitstellt (2). Ein gerätespezifischer Treiber kann über Ethernet auf das Multifunktions-Board geladen werden. Dieser Treiber kann unabhängig von der eigentlichen Anwendersoftware geladen werden, so dass ein austauschen der Treiberdatei bei einem Wechsel von z.B. einer USB-Kamera ausreicht.With this development it is proposed that the multifunction board has two serial interfaces (RS 232) and two USB ports for local expansion ( 1 ). In principle, all data available via these connections can be forwarded via Ethernet (e.g. to one or more control centers or servers). With this development, it is proposed to implement the connection of the USB devices, in particular USB video cameras and biometric sensor, to the multifunction board by means of driver implementation on the microcontroller of the multifunction board, which then provides the data in a standard format for one or more control centers ( 2 ). A device-specific driver can be loaded onto the multifunction board via Ethernet. This driver can be loaded independently of the actual user software, so that an exchange of the driver file is sufficient when changing from a USB camera, for example.

Mit dieser Entwicklung wird vorgeschlagen das Multifunktions-Board mit Schalt Ein und -Ausgängen zu versehen, welche Steuerungsaufgaben in der Umgebung des Multifunktions-Boards, lokal über eine vorbestimmte Software als auch manuell fern zu steuern sind.With this development is proposed using the multifunction board Switching inputs and outputs to provide which control tasks in the environment of the multifunction board, locally via a predetermined software and manually controlled remotely.
