Data Acquisition System is the process used to gather information from the hardware and machine to document or analyze some phenomena related to different industries. It sample signals to measure real-world physical conditions & convert the resulting samples into digital numeric values that can be manipulated by a computer.<\/p>\n
How does it work? <\/strong><\/h3>\nData acquisition process involves the sampling and converting of the electrical or physical phenomenon into data and recording the data into a computer. Examples of such events include measuring of temperature, voltage, current, sound, fluid flow, relative humidity, pH level, and more.<\/p>\n
Regardless of industry requirements and what the system wants to convert, all data acquisition software follow the same necessary procedure:<\/p>\n
\n- Data acquisition sensors must gather the data.<\/li>\n
- After data gathering, the sensors will output it on to signal conditioning circuitry for converting the data into an analog input.<\/li>\n
- The analog-to-digital converters transform the analog signal data into digital form.<\/li>\n
- The system inputs the singular digital form into the software. From here, now it can be accessed, and controlled by data acquisition software programs<\/li>\n<\/ol>\n
The main objective of any DAQ system software is to continuously monitor the data and control the power supply depending upon different industry testing.

<\/em><\/strong><\/p>\nFeatures of any DAQ software irrespective of any industry: <\/strong><\/h2>\n\n- The software has to be flexible enough to customize with the end-number of channels.<\/li>\n
- Must come with control capabilities such as closed-loop PID control, analog outputs, and discrete on\/off<\/li>\n
- Password protected graphical user interface (GUI) for local and remote system configuration, operation & maintenance with a text message and email alerts<\/li>\n
- Real-time data monitoring<\/li>\n
- Reusable data acquisition software library<\/li>\n
- Accurate timing and synchronization between multiple measurements including event triggering<\/li>\n
- Web server interface facilitates remote monitoring<\/li>\n
- An embedded computer for real-time processing, control and data storage<\/li>\n
- Multiple users for categorized working<\/li>\n
- Alarm setting for any technical issues<\/li>\n
- Accessible customized reports gathering from the real-time data storage and monitoring<\/li>\n
- PID toolkit enables flexibility in adjusting the parameters as per the project\u2019s requirements<\/li>\n<\/ul>\n

<\/a><\/p>\nWhat we worked on?<\/strong><\/h2>\nWe developed a thermal data acquisition system (TDAS) for one of the largest aerospace research organizations. <\/strong><\/p>\nWe designed and installed computer-based data acquisition and power control system for conducting a thermal test at 6.5M thermal vacuum chamber. The system consists of four central units-<\/p>\n

TSPU and PACU are VME based system. DPU is based on Pentium processor with hot redundancy using Redundant Array Of Inexpensive Disks (RAID) to handle the situation in case of failure of a server. Also, all the subsystems and peripherals are connected using TCP\/IP on Ethernet.<\/p>\n
The need was to record the data continuously every few seconds for several months.<\/p>\n
\n- We monitor numerous temperature sensors and telemetry & command signals of various types.<\/li>\n<\/ul>\n
