METHOD FOR DIAGNOSING A QUALITY SIGNAL, CONTROL DEVICE, CONTROL DEVICE PROGRAM AND CONTROL DEVICE PROGRAM PRODUCT

The invention provides a method for diagnosing a quality signal. A quality sensor installed in a reagent dosing system provides the quality signal. The method is characterized in that the quality sensor contains one signal processing system having a clock generator. The clock generator provides a time signal. The quality sensor obtains the quality signal according to time measurement. According tothe period duration of the time signal, the quality signal is transmitted to a controller through an interface. In the controller, the scale of the period duration of the time signal is obtained. A comparison is made between the scale used for the period duration and at least one period duration-threshold value. Additionally, a fault signal is provided when the scale of the period duration differs from the period duration-threshold value. 提出种用于对质量信号进行诊断的方法，被装入在试剂配量系统中的质量传感器提供所述质量信号。所述方法的突出之处在于：所述质量传感器包含个拥有时钟发生器的处理信号的系统，所述时钟发生器提供时钟信号；所述质量传感器根据基于时间的测量来获知所述质量信号；根据所述时钟信号的周期持续时间通过接口将所述质量信号传输给控制器；在所述控制器中获知用于所述时钟信号的周期持续时间的尺
