摘　　要：本文介绍了跳频技术在子母型数字多用表中的应用方法。该方法在保留多用表原有测量功能的前提下,增加了远程监视功能,此功能借助先进的跳频技术将母机测量的数据发送给子机,以达到测量值在母机和子机的液晶屏上同时显示的目的,从而满足高空、狭小等特殊作业环境使用。该表采用低功耗的PIC单片机作为处理器,以节约能耗,增加电池寿命。This article mainly introduces the application methods of Frequency-Hopping Technology in the Mother-Child Digital Muhimeter. Retaining the original survey function, this Multimeter also get the function of Long-Distance surveillance, that with the aid of the advanced Frequency-Hopping Technology transmit the data which surveyed by the Host to the Slave, so that the observed value can be demonstrated on the liquid crystal screens of the Host and Slave simultaneously. Therefore, this kind of Multimeter can be used in the high and small places and some other special work environment. This instrument used Low-Power PIC MCU as the processor, to reduce energy consumption and increase battery life.
