Two months after the government announced to seal off Wuhan, the epicenter of corona virus outbreak, the city starts emerging from the lockdown. As the transportation within the city is prepared to resume on March 28th, Guide Infrared (SZ.002414), a leading Chinese manufacturer of infrared thermal imaging systems based in Wuhan, has supplied Guide Infrared Fever Screening Systems to the transportation hubs, arming the subways, train stations and airports with a robust solution to prevent the resurgence of the virus following the increased traffic flow.
To ensure the health and safety of passengers, Wuhan Metro has put in place several measures, including daily disinfection and infrared thermometry while the soared the traffic flow will put a strain on the inspectors. A massive influx of people in the public is expected, meaning that a more effective and quick solution is needed to cope better with the situation.
In contrast with the traditional tools such as temperature guns, Guide Infrared automatic fever screening systems take the temperature of passengers while they are standing or moving several meters away, avoiding the close contact required by temperature guns and reducing the risk of infection. Powered by the AI-enabled facial detection technology, the system can automatically focus on a passenger’s face and sound an alarm when a person with a fever is identified, giving the inspectors an effective and efficient tool to deal with densely populated and fast-moving scenarios.
“We have conducted repeated experiments to guarantee that temperatures are being measured accurately from a long distance,” said Wang Peng, CTO of Guide Inferred. “To address the massive traffic volumes in the peak hours, we have developed the system to process the temperatures of hundreds of passers-by per minute.”
“For 20 years, Guide Inferred has set up a database based on mass temperature samples in a myriad of real-life scenarios. To deliver fast and accurate temperature measurement, the company has conducted constant algorithm optimization coupled with software and hardware upgrades, especially in the field of machine learning based on the neural network,” he added.
Apart from transportation hubs, the system is designed for other scenarios where a large volume of population flow is expected after resumption of operation. Many business complexes and schools have seen the installation of the system to prevent a second wave of infection.
From the SARS pandemic in 2003, the H1N1 Influenza pandemic in 2009 and the Ebola epidemic in 2014, to the COVID-19 outbreak in 2020, Guide Infrared has a proven track record of supporting global public health crisis, standing with the world in the prevention of diseases.
