一种脉冲对时信号扩展装置
摘要：
一种脉冲对时信号扩展装置。其包括CPU处理单元、时间保持单元、脉冲输出电路、主电源和总线；CPU处理单元通过总线与脉冲输出电路相连接，用于通过总线接收脉冲输入信号并转换成多路脉冲对时信号；时间保持单元为时间信号处理单元，其与CPU处理单元相连接；脉冲输出电路为多路对时信号脉冲输出电路，其输出六路对时脉冲信号；主电源分别与CPU处理单元和脉冲输出电路相连接；总线为CPU处理单元的外部总线。本发明提供的脉冲对时信号扩展装置可以将1路GPS脉冲对时信号扩展为6路脉冲对时输出，因此可解决变电站中GPS脉冲对时输出接口不够用的问题。
摘要（英）：

A pulse time tick expanding device comprises a CPU processing unit, a time keeping unit, a pulse output circuit, a main power source and a bus. The CPU processing unit is connected with the pulse output circuit through the bus, and used for receiving pulse input signals through the bus and converting the pulse input signals into multi-path pulse time ticks. The time keeping unit is a time signal processing unit and is connected with the CPU processing unit. The pulse output circuit is a multi-path time tick pulse output circuit, and is used for outputting six paths of pulse time ticks. The main power source is connected with the CPU processing unit and the pulse output circuit. The bus is an external bus for the CPU processing unit. According to the pulse time tick expanding device, one path of GPS pulse time ticks can be expanded into the six paths of pulse time ticks to be output, and therefore the problem that GPS pulse time tick output interfaces in a transformer substation are not enough can be solved.
