The normative bench is the device which allows to measure the air outlet temperature of thermal equipments (radiator, convector, towel dryer...) with the help of an arm on which are mounted three thermocouples.
The three thermocouples scan the entire surface of the air outlet grille and measurements are taken every second. During the test, we record on an Excel file the measured temperature values for each line and then we calculate the average of the measured values and note the maximum value of each line, which will allow us to conclude whether the device complies with the standard or not. The program is divided into four parts, which are:
- The configuration: which is the step where the operator must fill in the different dimensions of the radiator, ===> (I have already finished this step).
- The joystick or keyboard : which allows to move the arm manually in order to position it on the zero point of the air outlet grid, ===>( I already finished this step).
- The preheating: which allows to feed the radiator during 1 hour before launching the test, ===>( I already finished this stage).
- The monitor: which is the phase of the test; this stage consists in controlling the engines automatically, to recover the data of measurement on an Excel file and to provide a report at the end of test, ===>( has this stage it remains me has order the engines in an automatic way so that it ballait all the grid of exit of air by respecting the number of line which it must carry out as well as the estimated time. the number of line is determined according to the Height, the Width of the grid, the number se passage)
- The whole process is managed by a main program,
the operation during the test:
==>enter the dimensions of the radiator,
==> reset the motors << I can't write this part of the code in LabVIEW >> ==> move the motors manually to the right position
==> move the motors manually to the zero (0) point of the grid.
==> shift the two axes of -25 mm << I can't write this part of the code in LabVIEW >>
==> carry out the preheating for one hour
==> carry out the test
thanks in advance
