Verification and validation testing of aerospace components, notably pumps, valves, engines, is essential to ensure safe flight. Adequate testing requires exact replication of actual geometrical representation of component position within an aircraft. Further, it is quintessential to simulate environmental conditions surrounding aircraft during the flight. If the component is not subjected under real application conditions during testing...
When 4G technology was adopted in 2008, smartphone apps, streaming services and high speed internet access on-the-go became the norm. Regardless, there was little wireless advancement within production line factories and this is where a lot of 'Big Data' is produced. Sensor data and controls engineering is such a critical operation that it is never deemed safe...
PID Control System
PID control is the most common control algorithm in industrial control applications. This article is merely written to share some of the techniques that I developed in Labview Programming to achieve literally zero overshoot. In my case, I wanted to control hydraulics supply and return pressure via control valves. Such control valves take 4-20mA signal to control...
Programming FPGA and CRIO
In this article, I wanted to briefly go through few practices that I use to develop a compact rio application. A full Compact RIO controller combines FPGA with real time processor. Labview developer could utilise all target levels to develop machine app that would offer maximum resources utilization and reliability to mention only few of the...
Data Acquisition Systems Applications of data acquisition system
Data acquisition systems are required to test products prior being used in service or by public. Many products are required to be subjected to extreme conditions to ensure the product would still be operational and not detrimental to environment. For instance, air craft motor drive must be tested under same atmospheric condition that...
Standalone machine development
National Instruments c-DAQ 9181 and C series modules when paired together could be used to achieve complete measurement system. In such architecture, it is possible to transfer data between measurement system (composed of c-Daq chassis carrying c-series module) and labview app using wifi network, bluetooth or ethernet cable. I was once involved with designing weight machines using...
Servo Motion Control
In servo motion, a feedback sensor - usually encoder - is used to continuously measure position and speed of motor to correct motor speed. By using feedback sensor, we can get very accurate results. Most servo motors now have on-board 'Motor Encoder'. However, additional encoders could be placed on the actual mechanical axis to compare against actual line...
Today, vision monitoring is playing a vital role in stopping the spread of Covid-19 disease. Both inside and outside offices, vision inspection is ensuring people are keeping social distances. For decades, visual inspection has been an important aspect for industrial processes. Whether it is used for assisting in sorting bulk materials in pharmaceutical processing, inspecting the quality...
TCP/IP and UDP communication
Benefits of TCP/IP and UDP
Connectivity between devices is become very common and often beneficial essentially in industrial devices communication. Although Modbus, RS485 serial communications have its place still in industrial control and measurement applications, TCP/IP and UDP offers so much diversity that even apps written for I-phone and android could be used to connect with complete...
