Electronic Ceramic Test Program

Electronic ceramic is a ring-shaped component for submarines. When there is

a missile attack to a submarine, the ceramics mix the missiles brain by radiate

at certain frequencies and prevent the attack. Figure 1 shows this ceramic

component.

Figure 1 Ceramic

The program has some parameters and according to their tolerances, the

program decides whether the ceramic works properly or not. There are five

parameters which are capacitance of the ceramic(Cp), resonant frequency

value(Fr), anti-resonant frequency value(Fa), resonant impedance value(Zr) and

anti-resonant frequency value(Za). There are also four models of the ceramic

and according to the model, the ideal values and tolerances may change. My

purpose is to design a test program for ceramics to compare the values of these

parameters of a ceramic with the ideal values of them. If all the values are in the

range of the ideal values, the ceramic works properly. The panel view of the

program is seen in figure 2.

Figure 2 The Panel View

As seen above, the panel view contains the name of the technician that

uses the program, the registration number of him/her, the ambient temperature,

the model of the ceramic choice and time of using as inputs. When these are

filled by the technician, the program asks for the serial number of the component

and then, the program started to work and a frequency response graph is drawn.

y axis of the graph is impedance and x axis is frequency. When the graph is

completed, the parameter values are taken from the graph and the values and

passed/not passed conditions are written to the screen. The big black part of the

screen shows the passed or not passed condition. If it writes GECTI, it means

passed and the ceramic works fine. If it writes KALDI, it means not passed

and the ceramic does not work properly and at the left of the black screen, there

are passed/not passed conditions for each parameter. When the ceramic does not

work, we can see which parameter is the problematic one from these passed/not

passed conditions.

The program takes the screenshot of the resulting page when the test

program finishes to work and save it in the decided folder. The user decides the

folder that the screenshot will be saved before starting the program. Also, the

resulting values are written in an excel file and the user also decides the folder

that the excel file will be saved before starting the program. The resulting pages

for both GECTI condition and KALDI condition are seen in figure 3 and

figure 4, respectively. In addition, the excel files pictures for both GECTI

condition and KALDI condition can be seen in figure 5 and figure 6,

respectively.

Let me give detail information a little bit with pictures. The main screen is

seen in figure 7 with three pictures which are connected together.

Figure 7.1 The Main Page

Figure 7.2 The Main Page

Figure 7.3 The Main Page

When the input datas are written or chosen, the main page calls the

UserObject Hesaplama. It is seen in figure 8. In Hesaplama, the ideal values

of the parameters are set and saved to the system according to the chosen model.

After that, the graph is drawn. Ideal values and practical values which are

obtained from the graph are compared in the UserObject karsilastirma and the

resulting values and passed/not passed conditions can be obtained from the

output of karsilastirma. The others are obvious from the figures. It is very hard

to design the program but I have learned the program a lot during designing. The

UserObject karsilastirma and caphesap where the capacitor value is

calculated are seen in figure 9 and figure 10, respectively.

In figure 8.3, the model type MH-0000-0032 is shown, the other types are

similar to that except the ideal values of parameters.
