Abstract
método de ajuste de frequência padrão e de tempo baseado no oscilador de rubídio. a presente invenção refere-se a um método de ajuste de frequência padrão e de tempo com base no oscilador de rubídio, em que depois de o oscilador atômico de rubídio ser selecionado como a fonte de frequência de referência, o fpga realizará a multiplicação da frequência e a divisão da frequência desta fonte de frequência de referência para obter os sinais pps localmente gerados. o fpga também irá adotar os sinais pps de entrada externamente como referência para realizar a operação de medição de diferença de fase dos sinais pps intrínsecos. a diferença de fase medida será atribuída a um registrador especificado dentro do fpga e transmitida para o arm por meio de um barramento de dados. o arm irá calcular a mudança da diferença de fase entre os sinais pps intrínsecos e os sinais pps de entrada externamente com o tempo, e então, a diferença de frequência entre o oscilador atômico de rubídio e a frequência padrão externa, dessa maneira. a diferença de frequência calculada pelo arm será retornada para o fpga por meio de barramento de dados. de acordo com a tal diferença de frequência recebida, o fpga irá desempenhar a operação de ajuste de frequência do oscilador atômico de rubídio, para que as frequência de saída deste oscilador seja rastreada para a fonte da referência de frequência e de tempo de nível superior e sincronizada para a mesma. o efeito benéfico desta invenção é fornecer sinais de tempo de alto desempenho, alta estabilidade e alta precisão.
