"Is it like a green butterfly?" Zhang Pengfei turned his face to ask while using the joystick to remotely spray the machine 30 meters away.

On April 4, Zhang Pengfei, the second-level sergeant of the decontamination team of the Vulcan Hill Hospital Service Support Team, led his comrades to conduct the second decontamination of the medical personnel passageway.

Vulcan Hill Hospital has tens of thousands of square meters of area to be decontaminated, with one decontamination station, two decontamination posts, three decontamination areas, and 21 decontamination points. As the person in charge of the decontamination team, Zhang Pengfei has been "fighting" on the front line of epidemic prevention for more than 2 months.

"Destroy the virus without leaving a dead end, act!" Zhang Pengfei looked serious, and controlled an intelligent killing robot shaped like a tank, opening the way in front of the passage.

The camouflage green "tank" moves steadily to avoid obstacles moving forward at a constant speed, and sprays disinfectant sprayed with a bow. Sergeant Lu Jin "led" a cleaning robot to follow Zhang Pengfei. The robot's two black brushes cleaned the ground. Sergeant Mu Weijian and Corporal Wu Xiaobo followed suit.

At the end were soldiers Zhang Xu and Corporal Chen Xiaolong. They sprayed more than 30 pounds on their shoulders and disinfected 196 door handles, 90 switches, 17 transfer windows and 57 garbage storage points for medical personnel.

"Xing Luzhen and Hu Yashun, please answer, hear the operation in the contaminated area, and put on and take off protective clothing strictly according to the regional process regulations." Zhang Pengfei used the intercom to arrange the decontamination of the remaining points from time to time.

From February 1 to the present, Zhang Pengfei led the decontamination team to take charge of the disinfection of Vulcan Hill Hospital, cut off the source of virus transmission, and ensure the cleanliness of the environment.

On the day of the heaviest task, they worked continuously for 16 hours and completed the decontamination tasks of 421 admitted patients and more than 100 ambulances. After returning to the dormitory, everyone had a mark on his shoulder.

In fact, Zhang Pengfei and his comrades have groped a little bit today for the "human-computer complementary work flow". Compared with the original pure manual work, the work efficiency is greatly improved.

Not long ago, in the medical staff passage of Vulcan Mountain Hospital, Zhang Pengfei hung the fifth medal of third-class merit in his military career. He is also the only soldier in the army to support the Hubei Medical Team's achievements on the frontline.

"I am an ordinary soldier on the front line against the epidemic." As a soldier for 21 years, Zhang Pengfei worked as an infantry, artillery, reconnaissance, communications, oil and chemical defense, served as a command squad leader, coach squad leader, and platoon leader.

"Love army fine martial arts model", "learning talent model", "parade training model" ... no matter what position, he has done a good job; exercise training, competition competition, earthquake relief ... no matter what task, he has done an excellent job.

"In the special position of anti-epidemic, we also have to write a word of" your "to win no victory and never evacuate." Zhang Pengfei said.
