During the Sanfu season, the reporter visited a checkpoint at the Guiyang North Station of the Guiyang Branch of the People's Armed Police. Along the way, amidst the undulating mountains and towering buildings, a city painting of "coexistence of landscape and technology, integration of tradition and modernity" unfolds before our eyes. When it comes to the changes brought about by technology, Jiang Linxiu, a cadre of the same team, introduced: "Guiyang is a national level big data industry development cluster area, known as the 'China Valley'. Riding the fast train of technological development, more and more technological elements are 'settled' in the camp, and the means of duty for officers and soldiers are becoming more and more abundant." "The sky is never clear for three days, and the ground is not three feet flat," Guiyang, which is particularly hot and humid after the rain and the first clear day. Pushing open the car door, a sticky heat wave rushed towards me. Standing in the spacious square in front of the station, the journalist felt like he was in a huge steamer. Entering the guard room, I saw a huge screen occupying the entire wall. On the large screen, the monitoring images of each point are densely arranged to display the real-time situation on site. Guiyang North Station is the largest comprehensive transportation hub in Guizhou, and the sentry officers and soldiers are responsible for all-weather patrol work, with many tasks and heavy responsibilities, "Jiang Linxiu told reporters. Especially during the summer when there are many passengers coming and going, and the flow of people is large, it is difficult for sentries to fully grasp the situation of the station solely through foot patrols. In recent years, the detachment has collaborated with relevant local departments to develop an information system that connects various monitoring screens of Guiyang North Station to the standby room at the checkpoint. By using this system, sentinels can grasp the situation of each point without leaving their homes. Not only that, they have introduced artificial intelligence technology to create an AI duty assistant that integrates online inspection, intelligent analysis, and other functions. The AI duty assistant is like an intelligent 'sentinel', which can not only independently collect real-time data on passenger flow and surrounding traffic within the station, but also automatically identify abnormal situations and issue timely warnings. ”Jiang Linxiu said. In front of the workstation, the on duty sentry Li Qiankun orally spoke the wake-up key and issued instructions to the AI duty assistant: "Retrieve the monitoring screen of the west entrance and surrounding areas." As soon as the words fell, the corresponding monitoring screen appeared on the large screen. Previously, quickly retrieving surveillance footage was not an easy task, "said Li Qiankun. There were numerous surveillance points at Guiyang North Station, and before the AI duty assistant could" go on duty, "a sentry on duty was responsible for retrieving surveillance footage. Sometimes, in emergency situations, additional manpower was needed. Nowadays, with the help of AI duty assistants, the efficiency of duty sentries has been greatly improved, which can free up more time to provide support such as route planning and situation warning for patrol teams. ”Li Qiankun said. During the conversation, it's patrol time. After approval, the reporter joined the patrol team. The officers and soldiers of the patrol team are full of energy, with upright posture and vigilant eyes, patrolling the situation along the way. The scorching sun makes it unbearably hot and humid. Less than 10 minutes after departure, the journalist's clothes were soaked through. On the patrol road, a scene made the reporter very curious: the patrol team was always followed by an unmanned vehicle, which followed us wherever we went, flexibly avoiding pedestrians and obstacles along the way. Like AI duty assistants, it is another intelligent 'sentinel' for us. ”Li Qiankun introduced that this unmanned vehicle is a duty support equipment independently developed by the detachment, which can automatically sense the positioning sensors worn by officers and soldiers and follow the patrol team on duty. Li Qiankun opened the car cover and the reporter saw that various equipment and devices such as riot shields, explosion-proof blankets, and mobile warning posts were neatly arranged inside the car, resembling a "mobile equipment warehouse" that could meet the various duty support needs of officers and soldiers. In the past, some large and medium-sized duty equipment that was inconvenient to carry around was usually stored in the standby room, and in case of emergencies, only personnel could be sent back to the standby room to retrieve it. ”Li Qiankun said, "With this' mobile equipment warehouse ', common equipment and equipment can be taken whenever they are used, and the efficiency of handling special cases has been greatly improved." "The' suspect 'is found at the west entrance, and pay attention to the danger of' explosives'! ”During the patrol, a special situation report came through Li Qiankun's walkie talkie. The patrol team quickly rushed to the west entrance and carried out a practical training as planned. At the training scene, the cunning "suspect" used the building cover to continuously change the direction of escape, and soon disappeared from the sight of officers and soldiers. Seeing this, Li Qiankun immediately opened the AI duty assistant terminal carried by the unmanned vehicle, connected the information system of the standby room, called the corresponding point monitoring, and judged the escape direction of the "suspect". With the assistance of colleagues in the standby room, the patrol team re planned the search route and ran towards the target direction. Just when the officers and soldiers successfully surrounded the "suspect" and were ready to control it, a new secret came from the walkie talkie: "The suspect detonated" explosives "!" The officers and soldiers moved at the command, quickly took out the explosion-proof fence and blanket carried with the vehicle, and neatly completed the explosion-proof disposal. Along the way, the patrol team members were sweating profusely, with beads of sweat as big as beans rolling down their cheeks. Li Qiankun introduced that summer is the peak period for passenger travel, especially since July, the popularity of tourism in Guizhou has continued to rise, and Guiyang North Station has ushered in a peak in passenger flow. The patrol team regularly organizes case-based training to ensure efficient handling of unexpected situations. Training is over, patrol continues. When the patrol team arrived at the West Square of the station, they saw a passenger swaying and about to fall. Patrol team member Shen Pengcheng, with quick eyes and quick hands, rushed forward with an arrow and helped him up. After inquiry, it was learned that due to the scorching sun and the fatigue of the journey, the passenger suffered from some heatstroke. Subsequently, the officers and soldiers took out heatstroke prevention medicine from the unmanned vehicle and gave it to the passenger to take. Soon, his complexion improved. Shen Pengcheng told reporters that during the dog days of summer, it is common for passengers to suffer from heatstroke due to high temperatures and humidity. Therefore, they have placed commonly used medicines in the unmanned vehicle for emergency use. At noon, the scorching sun hangs high. Not far away, high-speed trains shuttle back and forth along the tracks. On the square in front of the station, a bustling crowd flowed endlessly, and the olive green safety shield became a reassuring scenery. (New Society)
