The most serious fault in the human-machine interface is the freeze of the operator station.The reasons why the operator station crashes are many and complicated.It may be caused by the overheating of the host caused by the cooling fan stopping,the overload of the CPU,the defect of the software itself,and the hidden dangers of the hard disk and memory.The operator should not panic when the machine crashes,but calmly and patiently analyze and find out the cause of the crash.
在人机接口中最严重的故障是操作员站死机。操作员站死机的原因很多，且比较复杂，有可能是冷却风扇停转导致主机过热，CPU负荷过重，软件本身有缺陷，硬盘、内存有隐患造成的等。操作员站死机时不要慌张，要冷静耐心的分析，并找出死机的原因。
