| Abstract: | In this paper,we analysised and summarized the thermal protection malfunction of DCS.Also,we proposed thermal protection to prevent malfunction and refuse to move of the device.For example,by optimizing the logical configuration,using mature technology,and reliable thermal control components,using redundant design and so on.And from the DCS system hardware and software,etc.we summarized the experience and described a number of measures to prevent the failure of DCS. |
