Abstract

This paper elaborates a concept for a wireless field bus communication with software defined ultra wide band with impulse radio modulation (IR-UWB) in manufacturing environments. A wireless field bus offers an important improvement to the smart factory due to increasing requirements for connectivity, adaptability and flexibility. Former analysis showed the benefit of using UWB technology for the wireless field bus transmission in manufacturing environment. In order to determine the best type of IR-UWB modulation a software defined radio system with direct sequence synthesizers is convenient. For this purpose on the transmitter side a digital-analog-converter (DAC) with 25 GS/s controlled by FPGA feeds directly the UWB antenna. On the receiver side the received signal is amplified by a low noise amplifier (LNA) and converted to a digital signal by an analog-digital-converter with as well 25 GS/s. The digital signal is further processed with a FPGA. This enables the adaptation of transmission parameters during operation. Thereby the transmission parameter, channels, antennas and RF components can be investigated.

在制造环境中使用软件定义的IR-UWB无线现场总线通信

本文阐述了制造环境下软件定义的超宽带脉冲无线电调制(IR-UWB)无线现场总线通信的概念。由于对连接性、适应性和灵活性的要求越来越高，无线现场总线为智能工厂提供了重要的改进。前面的分析表明，在制造环境中，使用超宽带技术进行无线现场总线传输是有好处的。为了确定IR-UWB调制的最佳类型，使用直接序列合成器的软件无线电系统是很方便的。为此，在发射端，由FPGA控制的25gs /s数模转换器(DAC)直接向UWB天线馈电。在接收端，接收到的信号由低噪声放大器(LNA)放大，并通过模数转换器转换为数字信号，速度为25gs /s。通过FPGA对数字信号进行进一步处理。这样就可以在运行过程中适应传输参数。从而可以对传输参数、信道、天线和射频元件进行研究。
