A modem in CMOS technology for data communication on the low-voltage power line

Communication over the power line network (PLN) referred as power line communication (PLC) has a long history of narrowband applications. With the recent developments in the field of digital communications, current interest is to exploit this medium for wideband communications for several applications such as Internet access, home networking, and in-vehicle data communication. In line with this recently emerging interest which envisions the conversion of a power transmission network into a communication network, understanding the root-mean-squared (RMS) delay spread is essential for multipath PLC channels for the establishment of reliable communication systems. In this paper, factors that play a role on the RMS delay spread value of low voltage (LV) PLC channels are articulated. Among these factors, dependency of the RMS delay spread on attenuation, loading, and physical characteristics of the communication channel in the PLNs is investigated.

Reading System

According to the current national conditions and the intelligent communities’ requirements on the electric energy metering system based on the broadband power line communication (PLC), this paper introduces a design program for achieving the remote meter reading through the broadband PLC technology. The system takes the high-performance single chip microcomputer and the Ethernet controller RTL8019AS as the core, the low-voltage power line as the medium of data communication, and makes the electronic meters access to the Ethernet via the broadband power line, thereby achieving the remote automatic meter reading. The multi-functional low-voltage power line remote meter reading system constituted by this system and the backstage management system together will have broad application prospects. In addition, this paper also makes a preliminary study on the reliability of the meter reading system.

Carrier Communication

Low-voltage power lines are not designed to transmit communication data; it is not ideal channel characteristics using power line as a data communication medium, especially the noise generated by the several of household electrical appliances will have a significant impact on the power line communication system. First, low-voltage power line carrier communication and channel noise characteristics are analyzed, and based on pure electricity environment UPS, the experimental results obtained with different electric appliances for data processing, and analyze the impact of the electric appliances noise on the power line carrier communication.
