US Military & Emergency Services Mobile Communication Systems, test and validation station
THE CHALLENGE
The client, providing solutions for the evolving needs of the modern soldier had a need to design and develop a new automated test stations where US military and emergency services mobile communication systems could be tested, meant to ensure that units have been assembled correctly and function properly. The client specifically requested the automated software test application for the US military and emergency services mobile communication test station was to be designed and developed with the NI (National Instruments) LabVIEW platform and development environment.
THE SOLUTION
We designed and developed an NI LabVIEW based, real-time data acquisition system software application to automate the testing and validation of US military and emergency services communication systems.
Provided with golden units, interface modules, test procedures and a schematic design of the UUT as well as the client’s test station, we used the NI LabVIEW programming environment to interface and communicate with the various devices such as microphones, speakers, switches, DACs and ADCs in the test station.
The mobile communication test station would generate a tone through each of the connected speakers and execute a test with the assigned microphones to determine if the tones detected were within specified decibel levels.
We also created a custom LabVIEW user interface, where through on-screen images, instructions and messages, the test operator was guided through the testing process to make the required connections before each test in order for the automated software to perform the required tasks.
Once all the elements had been tested and the process was complete, the measured data and a pass-fail result were visually displayed on screen. The test operator then had the option save and print a copy of the test report which would accompany the device under test through the various production stages.
Upon the successful completion of this project, we provided the client with the full NI LabVIEW source code for the automated test application as well as an automated test application installer executable and this test station could be replicated as many times as required to reach the desired production output. Additionally, the automated test application runs on the free NI LabVIEW runtime engine, so no additional NI LabVIEW licenses are required for any additional duplicate stations.
