基于GPS时钟的打铃仪设计

Design of Electrical Bell Controller Based on GPS

当前的打铃仪存在时间累计误差及多个打铃仪不能同步工作的问题。本文介绍一种基于GPS信号接收和PIC单片机的智能打铃仪的软硬件设计及其注意问题。实践证明,该打铃仪走时精确、可同步响铃。对该打铃仪的软硬件设计稍加修改,便可用于走时准确的万年历或能多机同步工作的时间控制器等,具有较高的推广应用价值。

Present electrical bell controllers exhibit many deficiencies such as accumulative error of timing and nonsynchronous rin ging. This paper introduces the software design, hardware design and some designing problems of electrical bell controller. The con troller is based on GPS and PIC microcontroller. Practice proves that the bell controller performs punctual timing and synchronous rin ging. With some improvement, it can be used in punctual electrical calendar and synchronous time controller.
