REXROTH电磁阀常见故障及修FF法？

REXROTH电磁阀在输入接口电路由CD4011四一二输入预非门集成电路及外围元件组成。主要是扩展每个通道的I/O输入，使每个通道可接两个相同或不同的探测器以提高探测准确度。只要有一路探测到信号就能使电路处于整备状态。输入接口是低电平有效，可接各种探测器。逻辑信号处理电路主要实现的是逻辑信号处理和输出逻辑信号，该部分本来想用门电路实现，但线路比较复杂，成本过高，可靠性不高，后来找到一种功能强大但很廉价的单片8位微处理控制器PIC12C508A，用它来做是Z好不过了，所有信号的处理都通过编程来实现，程序清单略。利用软件来实现大大简化了电路，降低了成本，提高了电路可靠性。原理图只是一种简单的方案（尽量利用所有的I/O口，做出尽可能多的控制通道来，Z多两个通道），其实通过修改程序，电路上增加三根地址线可以把通道数扩展为8个，对于一个比较大的公厕来说已经够用了。电路的单片机上有两个I/O口是做探头信号输入，两个是手动控制输入，还有两个是处理后的信号输出。电路用继电器来控制电磁阀，并且用达林顿管来驱动继电器，驱动力较强，减轻单片机的负载；继电器用大电流型的，保证电磁阀能正常工作。电源部分是普通的桥式整流加三端稳压模式，用了一片LM7805来稳压，电源充沛，可为多路探测器提供电源。三、电路功能本电路主要实现以下功能：平时便池没有人时电路处在待机状态；有人使用时探测器发出信号，该控制电路受到信号后延时2秒进入工作状态，此时，单片机不断检测探测器送来的信号，每一秒检测一次，一旦连续两次检测不到信号就进入延时阶段。如果此时有人按手动按钮冲水，则电路延时结束，进入待机状态，如果在5秒延时内没有人按手动按钮冲水，则驱动电磁阀冲水4秒。平时随时可按手动按钮冲水，按多久冲多久，松开后有4秒延时功能。
