For the safe operation of the system,the closed-loop controller must be operated redundantly,one in use and one in standby,and it is a hot standby.In order to make the redundancy successful,the following points should be noted:the hardware and software versions of the two controllers must be consistent;check whether the sending-receiving chip is in good condition;whether the redundant chip is in good condition.Check whether the settings of the two modules are the same,and also check whether there is a manual operation station.

为了系统安全运行，闭环控制器一定是冗余运行的，一用一备，并且是热备。为了使冗余成功，应注意以下几点：两个控制器的硬件、软件版本必需一致；检查发送-接收的芯片是否完好；冗余的芯片是否完好。两个模件的设定是否一样、还要检查有没有带手操站等。
