DJS130小型多功能通用计算机用于过程控制和实时处理时,一般都要求长期连续运行。可是,在实际使用过程中,常常发现交流电网供电电压瞬间跳变时,主机已设有的掉电/自动再启动功能不能实现,使之控制系统运行中断。对其产生的原因,本刊已于1970年第1期(章渭臣同志的文章)作了说明,这里不再重复。因此,为适应过程控制的需要,必须改进DJS130机现有的掉电/自动再启动功能。我
DJS130 small multi-function general-purpose computer for process control and real-time processing, generally require long-term continuous operation. However, during actual use, it is often found that when the power supply voltage of the AC power grid is suddenly tripped, the power-off / automatic restart function already provided in the host can not be realized, so that the operation of the control system is interrupted. The reason for its production, the magazine has been in 1970 No. 1 (Comrade Zhang Wei Chen article) made a description, not repeated here. Therefore, in order to meet the needs of process control, it is necessary to improve the DJS130 machine’s existing power-down / auto-restart function. I
