Abstract

"SISTEMA DE LEITURA DE MEDIDOR DE ESPECTRO ESPALHADO, DISPOSITIVO TRANSMISSOR CODIFICADOR DE PONTO EXTREMO DE MEDIDOR, E, SISTEMA DE LEITURA DE MEDIDOR DE UTILIDADE". Um sistema de leitura de medidor de espectro espalhado habilita o uso de transmissões de espectro espalhado de salto de freq³ência de alta potência (HPSS) em ambos os níveis de transmissor codificador e repetidor, do sistema de leitura de medidor. Uma pluralidade de dispositivos transmissores codificadores de ponto extremo são conectados, cada um, a um medidor de utilidade e transmitem sinais FHSS de alta potência contendo pelo menos dados de medição para o medidor de utilidade correspondente. Uma pluralidade de unidades de transceptor intermediárias que são em menor número que o número de dispositivos transmissores codificadores de ponto extremo, recebem e retransmitem os sinais FHSS de alta potência. Uma estação base inclui um receptor que recebe os sinais FHSS de alta potência. Preferivelmente, a estação base pode receber os sinais FHSS de alta potência a partir de ambos dispositivos transmissores codificadores e unidades transceptoras intermediárias, e as unidades de transceptor intermediárias agregam dados de medição de dispositivos transmissores codificadores múltiplos, antes da retransmissão em bloco dos dados de medição para a estação base. Preferivelmente, os sinais FHSS de alta potência são transmitidos a uma taxa de salto máxima de pelo menos um minuto por salto, para reduzir o consumo de potência e aumentar a vida da bateria dos dispositivos.
