Low Voltage Power Lines Carrier Meter Reading System Design

With the development of market economy, the residents and industrial power is becoming more and more popular, the traditional artificial meter reading way cannot have satisfied the requirements of the modern management. Based on the communication technology and the computer technology to be automatic meter reading system more and more get used.Power line carrier-current communication power system is a kind of special communication mode, the design of using220V low voltage distribution lines as the information transmission medium for data transmission. Power line network as the world’s largest network and its main function is conveying electric energy, but along with the development of information technology, the use of the natural electric network resources, realize the data communication, has less investment quick effect, and power grid construction synchronization, etc. Use of power lines to realize communication for electricity measurement management plays an important role. This design is based on power line carrier communication the meter reading system design, save to set up communication media resources, through the terminal to each watt-hour meter for electrical energy acquisition, again from the terminal to the data on, again by the concentration to the host. This design according to the national grid power low pressure set about the form of copy collector specifications, design the low voltage power lines based on the carrier meter reading modules.In order to be able to deliver stable reliable datain low voltage electric system, this design with based on a OFDM technology high speed field lines carrier transceiver chip. This design mainly expounds the carrier module circuit design, the carrier of the ground floor of the module driver development and point to some transparent transmission design and implementation of the scheme design and network design good module test and analysis.
