FeverSens Case Study

A Pneumonia of unknown cause detected in Wuhan, China was first reported to the WHO Country Office in China on 31 December 2019. The outbreak was declared a Public Health Emergency of International Concern on 30 January 2020.

The Civil Aviation Ministry has directed seven airports including Delhi, Mumbai, Chennai and Kolkata to make arrangements for screening of passengers arriving from China in the wake of outbreak of an infection caused by a new strain of virus there. Airlines flying in from any airport in China including Hong Kong have been asked to make in-flight announcements requesting passengers with history of fever and cough and travel to Wuhan city in the past 14 days.

The action-plan includes thermal screening of passengers to be undertaken. By Feb 2020, The Accuopt was the first on the Indian market employ thermal imaging camera to measure skin temperature, which may indicate the presence of fever in human body Accuopt introduces high accuracy Thermal Camera Fever Detection System (FeverSENS) to help tackle the spreading of deadly Corona virus. AccuOpt Supplied FeverSENS system to Seoul Korea, Indonesia, Taiwan and in Indian market. FeverSENS can be installed at Airports, Railway stations, Offices and any other places with large public gatherings.

The software can detect people with high fever, can raise an alarm and record the thermal and visual images. It is available in 384 x 288 Pixels resolution. It works at wavelength range from 8 – 14 μm. The modular thermal image processing FeverSENS software is designed to provide a view of thermal image in real time.

FeverSENS Software process the real time Thermal images & video. It detects any person with higher then the normal temperature. It stores the image and alert to authorized person. FeverSENS software is configured at threshold temperature and provides alarm indication when the target temperature rises above the threshold temperature.

Substation Monitoring System


Vedanta Limited is a premier manufacturer of metallurgical grade alumina and other high-quality aluminium products based in India. Vedanta Limited. (VL) is renowned for its superior metallurgical grade aluminam products. At Jharsuguda, Odisha, VL runs an international standard smelter with a current capacity of 0.5 mtpa.Jharsuguda are highly developed and self-sustained manufacturing unit that have finely integrated logistics, power and human resources.

Challenges for Vedanta at Jharsuguda Aluminium Plant

Vedanta faces many challenges in their switchyard areaas described below :

  • PFIC Area has many transformers, isolators, capacitor banks, Lighting Arrestors etc. where many
    connections develop hotspots. Prolonged hot spots at joints lead to breaking of the connection
  • So, Vedanta requires to monitor every joints, connectors of various components daily manually using a handheld Thermal Imager and prepare a report manually.

The above procedure of manually checking each and every potential hot spot locations by going to PFIC area is not only time consuming, error prone, it is also dangerous to the person who is monitoring it with Thermal Camera. Also, like every manual operations, such manual activity is error prone, slow.

Solution Provided by Tempsens

Tempsens Instruments Pvt Ltd has come up with a Solution, DCTMS ( DualCamera Thermal Monitoring System) which does automatic scanning of the designated PFIC area, identify all joints or potential hot spot location, measure temperature and prepare a report of them, highlighting any hot spot detected. HotSpot is decided as per threshold configured in the software.

DCTMS Configuration:

  • Two AST LTE 640 cameras (Visual + Thermal) installed at site on a High mast with canopy along with
    Pan and Tilt system which give 360° To and Fro motion. The Mast housed in such a way that one
    camera covers Half portion of PFIC area as well as equal portion of theswitchyard area being
    covered during rotation.
  • High end Server PC to process 2 Cameras on single Server/Machine

Tempsens DCTMS 640 requires1 Gigabit speed to transfer high resolution images to server class PC. The image have been acquired, displayed through AST InfraViewTM Software. Our PTZ system is suitable where the image has to be transferred centralized Control Room.

DCTMS 640 allows you to continuously monitor the temperature of hotspot locations in its PFIC area remotely at its control room. It scans the PFIC area for any hot spot in every hour and displays in a large TV screen. It also generates a sound alarm when any hot spot is detected.

Result Observed

DCTMS 640 – A Substation Monitoring System, Vedanta has been able to see the below benefits
➢ No more manpower used for manual measuring temperature to detect hotspot.
➢ It has saved manpower and minimized errors
➢ Timely and automatic reports
➢ Dashboard shows last detected hotspot for easy monitoring and maintenance
➢ Trend analysis for individual hotspot has helped identifying and rectifying hot spot prone joints easy and quick.
The ability within software to draw regions of interest is a real time-saver. Thermal imaging cameras, is providing an effective solution for measuring temperature to assess substation component reliability.
