微处理机(CPU)在医学仪器中日益广泛地应用。给从事医学仪器维修的工程技术人员提出了新课题,要求我们尽快掌握这类仪器的维修技术。本文通过简要分析带CPU的医学仪器的电路原理,推荐常用测试仪器和检修方法,介绍带CPU的医学仪器硬件电路的一般检修方法。一、电路原理带CPU的医学仪器的电路原理方框图如图1所示。
Microprocessors (CPUs) are increasingly used in medical devices. To engineering and technical personnel engaged in the maintenance of medical equipment put forward a new task, requiring us to grasp the maintenance of such instruments as soon as possible. In this paper, by briefly analyzing the circuit principle of the medical instrument with CPU, we recommend the commonly used test instruments and maintenance methods, and introduce the general maintenance methods of the hardware circuit of the medical instrument with CPU. First, the circuit principle The circuit principle of the medical instrument with CPU block diagram shown in Figure 1.
