Background Overview

During the COVID-19 pandemic from 2020 to 2022, many regions across the country faced severe pressure from community lockdowns, public area management, and epidemiological tracing. Traditional manual methods were inefficient and posed high risks, creating an urgent need for high-tech solutions to achieve precise prevention and control that is "contactless, wide-coverage, and highly efficient."action

CHENGDU TIMESTARS CO., LTD. actively responded to the calls of local governments and fully applied its mature TIM UAV system and drone technology to the front lines of epidemic prevention and control.

In the anti‑epidemic operations of multiple cities, CHENGDU TIMESTARS CO., LTD.'s UAV system played a key role as an "aerial epidemic prevention officer" and a "mobile command post."

1. Achieved efficient "contactless" patrol and public address

UAVs patrolled over communities, public squares, and rural areas, broadcasting epidemic prevention policies, notifying residents of nucleic acid testing, and advising crowds to disperse via loudspeakers from the air. This greatly reduced the workload of community staff and avoided the risk of cross‑infection from face‑to‑face contact.

2. Performed large‑area, rapid, and precise disinfection

UAVs equipped with spraying payloads carried out aerial disinfection of public areas such as locked‑down communities, centralized isolation sites, farmers' markets, and transportation hubs. Compared with manual disinfection, UAVs offer wider coverage, higher efficiency, more uniform application, and access to areas difficult for personnel to reach, effectively cutting off the environmental transmission chain of the virus.

3. Enabled management and emergency command of locked‑down areas

In key locked‑down areas, UAVs provided real‑time aerial monitoring of personnel movement and control. Once an anomaly was detected, they could immediately issue voice warnings and notify ground police for action, offering an "aerial eye" for efficient management of locked‑down areas and strengthening the epidemic prevention barrier.

During the epidemic prevention period, CHENGDU TIMESTARS CO., LTD. deployed its UAV system on a large scale and in a systematic manner, closely integrating "human prevention" with "technology prevention," and successfully established a new three‑dimensional epidemic prevention and control model featuring "aerial patrol, remote loudspeaker warnings, precise disinfection, and real‑time command." This model not only significantly improved the efficiency and safety of grass‑roots epidemic prevention efforts, but also provided strong technological support to governments at all levels at critical moments, fully demonstrating the irreplaceable strategic value and social benefits of UAV technology in responding to major public health events.
