background overview

From September 21 to 24, 2016, the 4th China (Mianyang) Science and Technology City International High‑Tech Expo was held in Mianyang, Sichuan. As a high‑profile international event with dense visitor traffic, it imposed extremely high demands on on‑site security, crowd monitoring, and emergency response capabilities. Traditional ground‑based security measures faced challenges of limited visibility and response delays.action

To ensure the safe and smooth operation of the expo, CHENGDU TIMESTARS CO., LTD., at the request of the public security department, provided aerial technical support for on‑site security, with core deployment of the TIM‑series UAVs and multi‑mission systems.

Intelligent Reconnaissance UAV: Features long endurance, high stability, and intelligent route planning capability, meeting the requirements for full-coverage patrol.

Tri‑Sensor Payload: Integrates a high‑definition visible light camera and an infrared thermal imaging camera, enabling reconnaissance and surveillance in all‑weather and diverse environments.

Loudspeaker Payload: Features high‑altitude loudspeaker capability for remote command.

1. Achieved seamless full‑venue monitoring and enhanced situational awareness

UAVs conducted routine patrols over the outer areas and core zones of the exhibition center, transmitting real‑time panoramic images of overall crowd density, vehicle traffic, and key area conditions to the security command post. This overcame the blind spots of fixed ground cameras and provided a global view and decision‑making basis for command and dispatch.

2. Enabled proactive crowd guidance and precise crowd flow control

When real‑time imagery detected excessive crowd gathering in a certain area, police could immediately use the UAV’s loudspeaker to remotely and efficiently guide and warn the target area, avoiding the risk of congestion and stampedes. At night, infrared thermal imaging was used to patrol closed areas, effectively identifying potential safety hazards.

3. Created strong deterrence and enhanced rapid response capability

The continuous presence of UAVs in the air, along with their audible and visual warning functions, created a powerful aerial deterrent against potential unlawful acts. In the event of an emergency, a UAV could quickly fly over the incident site to conduct preliminary reconnaissance and evidence collection, and guide ground police to the precise location for intervention, greatly improving the efficiency and safety of emergency response.

During the security operation for the 4th China (Mianyang) Science and Technology City International High‑Tech Expo in 2016, CHENGDU TIMESTARS CO., LTD.'s TIM UAV system successfully extended security dimensions from ground to air, establishing an integrated three‑dimensional security system of “monitoring – warning – response.” It not only greatly expanded the security team’s perception range, but also, through its unique interactive capabilities, achieved precise management and efficient crowd guidance over the massive on‑site crowd, providing crucial technological support for the safe and orderly hosting of such international large‑scale events. This was a successful application of the “technology‑empowered police” concept in a major real‑world operation.
