The invention relates to quality detection techniques used for heads molded through cold pressing and aims to provide a cold pressing head deformation quantity predicating method based on deformation-induced martensite phase transformation. The deformation quantity predicating method includes specific steps of conducting a head cold pressing molding test, performing finite element simulation in a cold pressing process and creating a relation curve of the deformation quantities and the martensite phase transformation quantities of the cold pressing head; using a ferrite measuring instrument for measuring martensite phase transformation quantities of areas of the cold pressing head requiring predication respectively; and substituting the measured martensite phase transformation quantities of the different areas of the cold pressing head into the obtained relation curve of the deformation quantities and the martensite phase transformation quantities of the corresponding areas respectively, so that the deformation quantities of the areas of the cold pressing head are obtained. By adopting the deformation quantity predicating method provided by the invention, curves of the deformation quantities of transition segments, straight sections and shell parts of different austenitic stainless steel heads can be determined and the plastic deformation quantities of the heads can be obtained conveniently, quickly and accurately by using the ferrite measuring instrument. The deformation quantity predicating method is very suitable for applying to the field of engineering.

Provided is a screen monitoring method. The screen monitoring method is applied to a digital teaching system. The method comprises that a screen picture of a teacher electronic device and a screen picture of a student electronic device are captured at the same time. Through a first image comparison method, the teacher picture and the student picture are compared to generate a first difference value. When the first difference value is greater than a first threshold value, the first difference value and a second threshold value are compared. When the first difference value is not greater than the second threshold value, through a second image comparison method, the teacher picture and the student picture are compared to generate a second difference value. When the first difference value is greater than the second threshold value or the second difference value is greater than a third threshold value, the screen picture, provided with an abnormal image, of the student electronic device is conveyed to the teacher electronic device.

A switch device and fault warning method suitable for substations. The switch device copies and accesses the general purpose-oriented substation event grouping. When the switch device judges that the general purpose-oriented substation event group triggers an abnormal state event, the switching The switch device generates an abnormal state event confirmation request and transmits it to the corresponding upstream switch device. When the switch device fails to receive a ready response from the upstream switch device, it sends a warning message, so that the initial trigger abnormality can be quickly and accurately known The switch device for status events for technical efficiency in maintenance.
