Activities in 2019

Summary: developed verification systems for silver ingots, integrating hardware with National Instruments vision and LabVIEW. Established WiFi testers for DSL modem repair, incorporating RF test probes and TestStand. Integrated measurement instruments for cosmetology clinical analysis. Created electronic card testers for coffee machines and supported GPON fiber modem production with TestStand.

The year 2019 was a dynamic period of innovation and technological advancement. Our team focused on developing sophisticated systems and solutions that enhanced quality control, testing, and production efficiency. We integrated state-of-the-art hardware and software to verify the authenticity of silver ingots, and we revolutionized the repair process for DSL modems with advanced WiFi testing capabilities.

Our commitment to precision and excellence led us to integrate measurement instruments for cosmetology, ensuring the highest standards in clinical skin analysis. We also tailored electronic card testers for coffee machines, demonstrating our versatility and customer-centric approach. Additionally, we bolstered the production line of GPON fiber modems with robust testing support, underpinning our dedication to delivering reliable and cutting-edge solutions. Each project in 2019 was a step towards redefining industry benchmarks and reinforcing our leadership in the field:

• Metallurgy - Verification of identification engraving on silver ingots: hardware integration and development of a verification system for identifiers engraved on 30 kg silver ingots in a foundry. This tester is based on National Instruments vision for cameras and LabVIEW communicating with PLCs.
• Consumer Electronics and Telecommunications - WiFi tester for DSL modem repair center: hardware integration and software development for testing modem PCBA cards under repair, with SMA cables, RF test probes, vector generator / analyzer, and TestStand.
• Life Sciences and Healthcare Technology - Integration of measurement instruments for clinical skin analysis for cosmetology based on LabVIEW.
• Consumer Electronics and Telecommunications - Electronic card tester for coffee machine: development of the test sequencer and instruments drivers for integration with a test bench manufactured by the customer. The solution is based on LabVIEW and TestStand.
• Consumer Electronics and Telecommunications - Support GPON fiber modem production line testers based on National Instruments TestStand

Increasing testability

For this project, my client asked me to increase the capacity of their test suites for your after-sales service: going from 500 units daily to 2500 units per day (units here are modems ADSL / VDSL telephone, HPNA, WIFI , WAN, Ethernet and USB.) Using benchmarks aftermarket in this case is to analyse and give a diagnosis to replace defective components and then verify that the repair has solved the problem.

Analysis

To optimize the test suites in the best way, the analysis is essential to decide what to do I found several factors that limited the ability.:

• too many manual actions: the test is unfair, well, whenever operator intervention The can not perform actions on another bank.
• b ank usability testing: the operator loses time to place the unit, connect and disconnect.
• software usability testing: test results are not clearly identifiable, the operator loses time to read the diagnosis, or worse, think again.
• false failures: if false failures, operator definitely test and the test is restarted, we lose time. False failures They can be caused by hardware (measurement instability due to instrumentation wiring, connectors or other components) and software (processing measurement, analysis, tolerance).
• the use of hardware resources: all tests are run one after the other, while some can run in parallel on the same drive or multiple drives.
• process: having a single bank, to execute all actions and testing is not always the best solution. The number and functions of banks depend on the product, the tests to be performed, the environment and why we test.
• optimization of the line: the placement of the test suites may penalize the flow, forcing the operator to waste time in their movement and increase the risk of handling errors that may damage the product.
• traceability: having the product history is important to optimize the repair, fluidize (not try a product that has been tested failed previous tester without any repair), diagnose problems l test Provide maintenance actions, but also to analyze production.

Solution

After presenting an analysis of the identification of problems, I worked with my client on several points:

• Review of the line and testers to improve the flow, ergonomics and movement of operators and products.
• use of the material now available, replacing and adding new, rewiring and connector type for better reliability and speed.
• l migration software testing from test scripts executed from the Linux command line to test sequences of TestStand on Windows by creating a simple screen (test in progress, good or bad result, pending test) to test parallelization to reduce the time.
• test report generation, data centralization in the network and development of data analysis software.
• operator training and actions optimization.

Conference "LabVIEW Embedded Systems for variables monitoring "

Summary: AJOLLY Testing’s recent conference showcased our cutting-edge remote monitoring solutions using National Instruments’ LabVIEW. We demonstrated the power of LabVIEW embedded systems through a live cross-continental interaction, controlling a cooling system in Paris from Mexico. Our session covered the essentials of control, monitoring, and testing, and featured a detailed look at our Paris system’s hardware and software. We also introduced LabVIEW’s capabilities, including shared variables and web server functions, emphasizing our commitment to innovation in industrial and scientific systems. Join us on our blog for insights into our advanced telematics engineering solutions.

It was a pleasure to give a conference about industrial and scientific systems of National Instruments during the international conferences in telematics engineering at the Polytechnic University of Durango, Mexico. During one hour I developed the theme of "LabVIEW Embedded systems for the variables monitoring": definition of what are the control, monitoring, simulation, test and measurement, a demonstration of programming with LabVIEW, a live video with my client at the Raspail Institute of Paris in France, to describe a cooling system using components from National Instruments and an embedded LabVIEW software I developed, to demonstrate the capabilities of remote control of the machine installed in Paris from Mexico.
