摘要
以单片机为核心,采用软件、硬件相结合的方法,充分利用单片机的硬件中断资源,实时响应地面的声波逻辑脉冲,分离其接收和发射逻辑。同时该仪器以地面声波逻辑为工作时序,分时采集模拟道数据、脉冲道教据及向地面传输 PCM 数据。该脉码传输仪既能完成 PCM3506的全部功能,又能监测仪器工作环境的温度及测井套管接箍的压力。
By using MCU as a core, integrating software with hardware, the interrupt resources of MCU hardware are fully used for a real-time responding of ground acoustic logic pulse,separating re- ceived and transmitted pulses. In the instrument, the acoustic logics are used as working time se- quence for collecting the data,such as analog data,pulse data and PCM data by time sharing. The in- strument can not only perform the functions of PCM 3506,also can monitor the working temperature and pressure on logging casing collar.
