In the early morning of January 21st, 2022, led by the Beijing Fire and Rescue Brigade, organized by the Daxing District People's Government, together with relevant departments, an all-element comprehensive practical drill for fire and rescue in subway tunnels was organized and carried out at Daxing Xincheng Metro Station. The entire drill mobilized 10 fire detachments, 52 fire trucks and 248 fire rescue personnel to participate. Two thousand-degree high-temperature resistant fire-fighting robots and one explosion-proof fire-fighting and scouting robot from Lesen Technology appeared as important combat forces.

The drill closely focused on the characteristics of complex building structure, high temperature smoke accumulation, high personnel density, and difficulty in evacuation as well as rescue and communication support in the subway tunnel fire accident. Real simulation of the whole process of firefighting and rescue of "the train stops due to a fire caused by a line failure during the journey in the train tunnel". A train bound for Caoqiao was 2 kilometers away from Daxing Xincheng Station. Due to a line failure, the air conditioning system of the car body caught fire and it stopped at the No. 1 air shaft in an emergency. The high-temperature smoke quickly spread into the carriage and the tunnel, causing a large number of passengers in the train to be comatose and trapped. The subsequent trains stopped at Daxing Xincheng Station in an emergency.

After receiving the alarm, the 119 command center immediately mobilized fire and rescue personnel to the scene. As the fire spread, the temperature of the tunnel rose sharply, and thick smoke filled the air. At the critical moment, the thousand-degree high-temperature fire-fighting robot was dispatched in an emergency, and quickly entered the accident scene under the remote control of the operator. Through thermal imaging technology, it directly attacked the "zero-distance reconnaissance" inside the fire scene, providing reliable data for on-site rescue decision-making. At the same time, the thousand-degree high-temperature fire-fighting robot approaches the fire source under the control of the operator, and sprays a strong water column to quickly suppress and prevent the fire from spreading. Under the leadership of the thousand-degree high-temperature fire-fighting robot, fire rescue personnel quickly opened up rescue channels and began to carry out combat tasks such as evacuation and rescue, internal attack fire extinguishing, smoke exhaust, and lighting. In the end, the fire at the accident site was successfully extinguished, and all the trapped people were trapped. Rescue, the whole exercise ended successfully.

The robot empowers various firefighting and rescue operations. The unique high-temperature performance of the thousand-degree high-temperature fire-fighting robot gives it an unparalleled combat capability. It can not fear the threat of high temperature and flame, and can replace the rescue personnel to enter high-risk environments for operations. The four advantages of distance reconnaissance, zero-distance cooling, zero-distance fire extinguishing, and zero-distance persistence" solve the pain point that traditional fire-fighting robots cannot enter the high-temperature core area of the fire field, especially suitable for various large petrochemical enterprises, tunnels, subways, etc. High temperature, toxic gas leakage, explosion, collapse and other complex fire environment.

In the whole process of participating in the performance, Qiandu high temperature fire-fighting robot took the lead, acted at the moment of danger, cooperated with fire and rescue personnel tacitly, showed great power, and played an important role in reconnaissance, fire fighting and other aspects. In the future, it may become one of the main scientific and technological means of subway tunnel rescue, effectively assisting subway tunnel fire disposal work.
