Meter Reading System Research Based On SC1128 Low-Voltage Power Line Carrier

At present, the low power line carrier communication system of the domestic and foreign civil still has many problems. Such as the Meter Reading systems in the use all are not can achieve 100% and the punctual request. This article is for the purpose of using the low power line power supply network low cost, high reliable characteristic, studies one kind low power line carrier communication: Meter Reading systems, which suits our country's low power line characteristic. This article made more overall comprehensive analysis to the electric power line carrier communication medium low voltage power line of force channel characteristic, Proposed power line carrier communication system, which bases on the spread spectrum communication, namely the application of spread spectrum communication chip SC1128 in the low voltage power line, initially completed the point-to-point communication experiment system design, the manufacture and the debugging. In order to cause the system to communicate under a more real environment, in order to debug systematic each related parameter better, appling the communication on the intelligence hot flow meter datum transmission system. Looks from the system communication effect, this system has a higher antijamming, the anti-signal weakens ability, the system can achieve a farther transmitting range, simultaneously because the communications system essential part SC1128 (Spread Spectrum / solution expand chip) is specially designed according to the domestic low power line characteristic, the performance price is high, these are all advantageous to the system's promotion.
