Abstract:
In the manufacture of aircraft there are systems - systems that are very complex and must be integrated with each other, these systems are integrated with each other with wireharness transmission media. Wireharness is a collection of cables that are tied to form a bundle into a single unit. The continuity testing tool available today uses a multimeter, the disadvantage of using a multimeter is that it takes a long time to carry out because it must be tested one by one point to be tested while there are quite a lot of points to be tested, both operators often have difficulty when looking for cable addresses on the wirelist, the three tools used are not flexible. The purpose of this research is to design and make an aircraft wireharness continuity test tool that can test quickly because it can test many points at the same time, makes it easier for operators when looking for cable addresses on the wirelist, and is flexible when testing because it can measure two points that are quite far apart. far compared to a multimeter probe. This tool has two parts master and slave and each part uses an Atmega328p microcontroller-based controller as a data processor. Then also used 2 CD74HC4067 ICs, namely a 4 to 16 line multiplexer/demultiplexer whose binary output is controlled by a microcontroller. As well as for unidirectional communication between master and slave using NRF24l01+ (wireless). To operate the tool and display the results of the wireharness test, an application program was created using Visual Studio 2010 with the Visual Basic programming language. The system created will be realized into hardware capable of conducting a continuity test of 32 connection pin points in a multipoint to multipoint manner. After all systems are realized, then further testing is carried out on the tool, where this test is carried out to find out whether this tool can operate in accordance with what was planned. In continuity testing with this tool, it is able to produce good tests because it is able to carry out multipoint continuity tests and the communication distance between master and slave is 20 meters, and the testing time using this tool is 46.2% faster than using a multimeter. By using this continuity tester to speed up the work, the result is safer because the cable connections are not confused, can test the connection is disconnected or connected.
