| 摘 要： | 旧船上SMA-02型报警系统是采用继电器控制电路实现的,由于继电器电路触点裸露、容易进灰尘及受外界因素影响,故障率高,故障原因难于查找和排除。使用可编程序控制器(PLC)取代它,可以大大改善其性能。

| Abstract: | The SMA-02 alarming system which is widely installed in the old-type ships adopts relay control circuit as its central component. Due to the fact that the contact points of the circuit are exposed in the air and the environmental factors, such as dust etc. The malfunction rate is high, and it is difficult to check and eliminate. Replacing with PLC, its performance can be improved significently. |
