【Abstract】 An integrated acquisition terminal, which can communicate with other devices through electric power line carrier, is designed for the pulsed electric energy meter. Using dual CPU shared data memory technology, the real time problems of pulse count and power line carrier communication are resolved. Using pulse processing hardware circuit and CRC(Cyclic Redundancy Check)coding and decoding technique, the pulse collection and long distance pulse signal detection with low cost, high reliability and anti interference capability can be realized. The related techniques can be extensively applied to other pulsed pressure or flow meters.更多还原
