风阀控制器中固态继电器的过载保护

Over loading protection for the solid state relay of wind valve controller

在每个固态继电器的输出端串联一只电阻 ;检测电阻两端的电压可获得输出电流 ;当发生过载时产生中断 ,由中断服务程序检查出哪一个输出点发生过载。

A resistance is series connect ion at output of each solid state relay to check the voltage at both sides of re sistance and gain the output current.When over loading happens it will be brocke n and find out which point produced over loading by checking the intermissi on service program.
