AbstractThe communication system of a microgrid can transfer the information of electricity price, power consumption and so on between users and the control centre. This capability is of great significance to improve the efficiency and sustainability of power facilities. In this paper, a bidirectional DC–AC converter topology is proposed to achieve the composite transmission of power and signals in microgrids. Since the transmitted signals are modulated by power switches of converters and integrated into the currents, the cost of signal couplers can be saved and the circuit structure can be simplified. In order to verify the feasibility of the proposed method, a simulation model of the proposed converter is implemented in MATLAB/Simulink. With the power supply frequency of 50 Hz, when the converter operates in the inverter mode and rectifier mode, the data transmission rate can reach 120 bit/s and 48 bit/s, respectively.

The Voice

In this paper, we implement a voice data communications between sender and receiver through Wi-Fi. The system was designed and implemented using network stream protocol which was developed by National Instruments on Lab-VIEW between two devices. The device which acts as the sender was My-RIO board and the receiver device was Personal Computer. The voice data communication system was tested by observing the effect of various buffer sizes on the throughput, latency and CPU usage. The result showed that the larger the buffer size being used, the throughput values were also getting bigger. However, particular buffer size made the throughput became saturated. The change on the buffer size also directly affects CPU usage. It seemed that the buffer size did not affect latency significantly. It showed that the latency was stable with an average of 13 milliseconds on voice data transmission.

Wireless Data Communication

As a kind of wireless communication, Infrared wireless data communication has been developing rapidly and has been widely used in the close wireless data communication. In this paper, there is the design and achievement of infrared communication system, which has realized the short distance transmission of voice and digital signal (temperature signal). The modem part of the system is implemented by the phase locked circuit composed of LM567. At the same time, with the single chip processor as the core, the temperature information which has been encoded is added to the audio signal and then to be transmitted to the receiver to be decoded to restore the temperature information. After the test of implementation, this system can transmit the speech signal and digital signal directly and the voice signal received has no obvious distortion. This system is simple in making and has a good application prospect.

Hearing aid is an electronic gadget precisely used into the internal ear which reestablishes halfway hearing to smooth hearing. The discourse processor of CI parts the sound-related sign into groups of various frequencies and changes over them into appropriate codes for animating the cathodes in cochlea of ear. The cathode actuates sound-related nerve filaments to give hearing sensation. The expense of the CI alone goes to around 100,000 US dollars. For the efficient less well-to-do individuals with hearing sickness, it might be too exorbitant to even consider affording for this hardware to recoup from the conference misfortune. It gets important to cut down the expense. The cost decrease might be accomplished with diminished region, low force and rapid activity of the CI. This goal intuited both the simple and the computerized based CI originators to inquire about their techniques to give individuals less expensive and profoundly understandable CI. The primary objective of this paper is to develop reconfigurable DSP architectures for the filter banks in speech processor of CI with the following features like minimized area of the filter, reduced power consumption of the speech processor and enhanced presentation of the filter. This paper involves the design and hardware implementation of narrow band pass FIR filter for speech processor of CI using the Xilinx System Generator (XSG) tool on Virtex 7 FPGA.
