Some Cool Title
The central processor of the control unit in this project is ARM-NXP LPC1788.
The following video shows the performance of the condom test system with this control system.
Design and development of a central control system for the testing sanitary condoms v2.1
This control unit is used in the test device for condoms. In this device there are many mechanical, electromechanical and pneumatic systems that must harmonize with each other. In condom manufacturing factories, it is necessary to test condoms for the absence of holes after initial production. This test is carried out with an electronic testing device or ET. The basis of this device is to create a high-voltage circuit. If the condom has a hole, a short circuit occurs in the circuit and the device rejects the condom.
A header board based on the ARM-NXP LPC1788 microprocessor is used in this control system. The central controller communicates with the high voltage drivers via DB9 terminals.
Below you can see photos of this control unit in the research and development phase.
The following illustrations show the preliminary stages of testing and manufacturing this control unit.
