Servovalve Test System for Aerospace Industry

Our client, an Aerospace Test, Service and Repair house, was exploring ways to perform a Frequency Stimulus/Response test on a Brake Servovalve. The manufacturer's test methodology is very old and most of the products are already unobtainable or obsolete.

The Brake Servovalve is driven by controlling the current supplied to the different coils. Hence, the test specifications required the Brake Servovalve to be put through a varying frequency current and derive the valve's response to the stimulus current signal.

Using NI PXI system and modules, we were able to develop a complete turn key solution for their Brake Servovalve Test.

Headless Remote System for High Speed and High Channel count vibration data-logging

Our client, a defence research company, engaged us to develop a headless CompactRIO system to work with their 3rd-party mission computer to record vibration data from 32 channels of accelerometers on to a USB SSD drive.

Using LabVIEW and its ability to handle customized UDP or TCP commands, we were able to meet the customer requirements to communicate with their 3rd-party system. And with CompactRIO's FPGA capabilities for high speed recording, recording all the vibration data at full speed is not a problem.

System Specifications

NI CompactRIO 9082

8 X NI-9234

USB SDD

** Software design is restricted due to confidentiality.**

(System operating at 51.2kS/s x 4bytes x 32ch = 6.5MB/s throughput)

High Channel Count Synchronization of Analog Inputs and Outputs of PXI DAQ System

Our client engaged us to develop a high channel count synchronized analog input and output program using NI DAQ hardware. They had strict synchronization requirements for their analog input acquisition across multiple DAQ card together with their analog output signal.

Using NI DAQmx devices, with great timing and synchronization specifications, we were able to come up with a solution for our client using NI products and design the LabVIEW application to control the hardware timings to meet their specific requirements.

We also provided the client with a playback application to read their acquired data file to ensure that we have met their timing requirements.

Process Monitoring of pH and ORP of Acid Wash Tanks from Manufacturing Plant (Industrial)

Our client is a major manufacturer of cycling components. Their current manufacturing process of acid washing the components faced intermittent quality issues which they had difficulty pin-pointing. Our client engaged us to develop 24/7 Process Monitoring solution* of their pH and ORP Process with the requirements below:

1. Display of Daily Trending of Acid Wash Process

2. Real Time data with Alarm if exceed defined threshold

3. Database feature to look up historical data

* KEC Process Monitoring solution is a proprietary architecture design based on LabVIEW that allows scalable implementation of Industrial Processes (e.g. ONE system to Multiple systems). *

Custom Force Measurement Acquisition from Wafer-Breaker System (Semiconductor)

Our client is a major semiconductor manufacturer of LED wafers. The current 'Wafer-Breaker System' cuts the wafer into its individual LED die; however, there is no way they could acquire the data from each cut from the current machine though there is a load cell connecting to the cutting mechanism.

Our PXI system solution measures directly from the load-cell unit; together with a digital trigger to synchronize each cut from the system, we are able to acquire the waveform of each cut from the load cell (~400 cuts per wafer). Our software application automatically synchronizes with the digital trigger and Timestamp to categorize the wafer data by folders accordingly based on Date/Time. The data is saved as an image for our client's reference; and a custom analysis to find its peak load is built within the software.

Un-interruptible Vibrations Measurements and Data-logging System

Monitor vibrations from 2 three-axis accelerometers to detect high-impact shocks that are abnormalities. The system will automatically detect the shocks, measure the resultant vector acceleration, records date/time and all data into an Excel format; as well as having an interactive Graphical User Interface to display system data and allow user control and configuration.

Features:

- Continuously monitors acceleration from both accelerometers independently

- Detects, Display and Records high-impact shocks that occur

- Built-in storage allows for long period of recording

- Un-interruptible Power Supply prevention system in event of sudden power loss.
