As the person in charge of venue operation and security of Huafa Property of Hengqin International Tennis Center, Zeng Yajun's day began with "waking up" the entire venue. With 8 years of experience in venue operation and maintenance, Zeng Runner-up has walked all the way from the venue of the 2010 Guangzhou Asian Games to the stands of the Hengqin International Tennis Center, which has hosted the Zhuhai WTA Super Classic and the ATP Zhuhai Championships.

"Wake up" the venue in place

During the tennis event of the National Games, at 6 a.m., he appeared in the strong motor room on time, and the moment he pressed the main switch, the pointer on the dashboard beat smoothly, and the whole venue woke up from silence. Immediately afterwards, he had to check the low-voltage power room and weak motor room one by one to confirm the signal strength of the competition private network and the event Internet.

He has completed the first round of global inspection: whether more than 300 emergency indicators are on, whether more than 700 fire safety exit signs are powered normally, and whether the all-in-one machine in the media area and news area can be broadcast smoothly. "These downlights and signs must ensure that they can be lit for 60 to 90 minutes after the power is cut off, which is critical."

Before the start of the game, his special support team composed of 31 people conducted a comprehensive "physical examination" of the venue: the information system support team monitored the operation of the equipment throughout the process to ensure that there were no abnormalities in various data services; The engineering maintenance team replaced 20 parking lot lights, debugged the outdoor arena audio, replaced the microphones in the press conference hall, carefully installed 196 mobile phone holders in the bathroom, added faucets to the garbage room, and replaced several sewer drains...... Clear the "small problems" of the venue one by one in advance.

After the evening game, he had to wait 2 hours before getting off work. Turn off the large screen, turn off non-essential lights, check the operating status of the equipment in the computer room, and confirm that the hot water room is operating at full capacity 24 hours a day. "Athletes and reporters should take a bath and drink water after the game, and the hot water supply cannot be interrupted." At the end of the day, the electricity consumption of the venue soared from the usual four to five thousand degrees to tens of thousands of degrees, and behind each kilowatt-hour of electricity, there was a figure that he repeatedly checked.

Detail makeover

"Welding" safety in the bones

During the preparations for the National Games, Zeng Yajun and his colleagues replaced a large number of hardware facilities. According to the security regulations of the organizing committee, in order to meet the requirements of face recognition for venue cameras, they upgraded more than 400 cameras, all of which were updated to domestic cameras, which not only have clearer image quality, but also can be directly connected to the public security bureau, greatly improving the safety factor. "The venue is crowded and complex, and facial recognition can quickly investigate hidden dangers and ensure the safety of the venue."

The transformation of the emergency sign took him a lot of effort. After testing them one by one, he decided to replace them all with models with stronger battery life, and replanned the installation position to ensure that no matter where he was, he could clearly see the direction of escape. In addition to safety facilities, he also stared at the "invisible" lines. He personally laid and debugged the power connection lines for TV broadcasts, the temporary power supply of tents, and the spare sockets in the press conference hall.

Sudden disposal

Be the "reassurance" of the venue

Eight years of venue operation and maintenance experience have made Zeng Yajun a "veteran" in dealing with emergencies. In order to cope with possible power outages, he formulated an emergency plan in advance, coordinated with China Unicom, China Telecom and China Mobile to make backups, and also prepared emergency power generation equipment in the computer room. "The temperature of the computer room must be controlled below 25 °C, otherwise the equipment is prone to failure." He pointed to the air conditioner in the computer room and said that even in summer, it must be kept cool, and he will record the temperature regularly every day to ensure the stable operation of the equipment.

Zeng Yajun's "reliability" is never just talk. The stable operation of the competition private network, the comprehensive upgrade of emergency facilities, and the rapid handling of emergencies are all obtained by him with 8 years of experience and countless days and nights of perseverance. This is the Huafa people, in ordinary positions, with professionalism and perseverance, to build the most solid backing for the National Games.
