At present, the Centre has the capacity to carry 28,000 racks and 360,000 servers to meet cross-regional data calculations and information synergies and to contribute to the financial, Internet and cloud services of the capital economy.

For urban residents of the capital city, Beijing has created a two-gug network of “high-speed” telecommunications, with 80 per cent coverage in gigabytes, and a combination of gigabytes, WIFIs and G5G has provided citizens with a network environment that is readily accessible.

Targeted clients, Beijing telecommunications provide an inexpensive gigabytes from outdoor to indoor, from urban to peri-urban areas; and continuously upgrade key capabilities, such as upward mobility and 5G high-precision orientation, around critical demand for industry applications.

The Beijing telemetry, industrial digitization, AI, big data, and cybersecurity focus areas, provide deeper and deeper ecological cooperation with businesses and promote the integration of the 5G applications into the production of energy. In recent years, the Beijing telecommunications industry has worked together in three major industries, namely, China and China, to build a fully equipped manufacturing 5G-compatible plant for the digitization of aided industrial enterprises, and to undertake a comprehensive exploration with Gin-East logistics in the area of 5G+ logistics, promoting the application of the 5G intellectual warehousing.

At the same time, telecommunications in Beijing are used in a robust manner, based on the innovative capabilities of technologies such as 5G and AI, through autonomous research and development of systems such as AVAR glass inspections, four full machine checks, the MaartAI patrol, five G+AVP parking.

After receiving the alarm, Zhangshu fire rescue brigade immediately dispatched 2 vehicles and 12 people from hope road rescue station to deal with it.

When firefighters arrived at the scene, they found that the tank car loaded with 30 tons of hydrochloric acid overturned into the trees next to the national highway.

The tank body has been disconnected from the front of the car, and a small amount of hydrochloric acid has leaked. Fortunately, the driver of the tank car has extricated himself from the difficulty, and there is no serious harm to his health.

The commander immediately ordered to quickly block the scene, set up a cordon and evacuate the onlookers.

A group of firefighters wear protective equipment and carefully check the tank for cracks and hydrochloric acid leakage.

Meanwhile, another group of firefighters sent out a water gun to continuously dilute the hydrochloric acid on the vehicle body surface.

After the crane arrives at the site, lift the disconnected locomotive and straighten it.

In order to ensure no secondary leakage, the commander ordered the tank to be hoisted to the road after emergency discussion by various departments.

During the lifting process, firefighters sent out two water guns to cool and dilute the tank.

After an hour and a half of emergency treatment, the accident vehicle has been successfully lifted. Firefighters immediately diluted the leaked small amount of hydrochloric acid and handed over the scene to the traffic police for further treatment.

According to the driver of the dangerous chemicals transport vehicle, the accident occurred because the road was wet and slippery in rainy days, the rear vehicle suddenly cornered to overtake, and the driver braked hard to avoid, resulting in the vehicle rollover.

The scene of traffic accidents caused by slippery roads in rainy days is often shocking.

On October 19, in Xintian Town section of Yici highway, a small truck skidded on a rainy day and hit a large truck approaching.

On October 18, in Xiaogang section of national highway 105 in Fengcheng City, a tricycle collided with a truck due to slippery road in rainy days. The front part of the tricycle was seriously deformed, and the driver was trapped and the cab could not move.

In rainy accidents, drivers often make a common mistake - not reducing the driving speed.

Yichun fire once again reminds you to keep in mind when driving in rainy days.

Speed reduction, distance control and bright tail<<

Pay attention to these when driving in rainy days.

There are two key points to the impact of rainy days on safe driving: the deterioration of driver’s vision and the decrease of tire adhesion caused by wet and slippery road surface.

For poor vision, drivers should pay attention to:

◆ check the wiper before going out to ensure it can work normally and remove rainwater;

◆ if the window is foggy during driving, the air outlet mode can be adjusted to demist mode, and the cold air or warm air can be turned on to disperse the fog;

◆ use lights correctly. If the visibility is reduced due to rainfall, turn on the headlights, clearance lights and rear position lights in time, not only for lighting, but also for other traffic participants to notice your presence. In addition, it should be noted that when the rear vehicle driving in the same direction drives close to the front vehicle, the high beam lamp shall not be used.

For the decrease of tire adhesion, drivers should pay attention to:

◆ control the speed and do not brake hard. If the road is wet and slippery in rainy days, reduce the speed and enhance predictability. Avoid sudden acceleration, sudden braking and sudden direction during driving, otherwise it is easy to lose control of side slip.

◆ turn slowly and don’t turn sharply. Driving in rainy days is easy to sideslip when turning, so turn slowly and return to normal speed after turning. Turn the steering wheel gently, not slamming the steering wheel and slamming on the brake.

◆ try to reduce overtaking and merging. It is more difficult to control vehicles in rainy days than in normal weather, so try to reduce back and forth merging and overtaking, and try to follow the car without competing for the road.

◆ increase the distance between front and rear vehicles. On rainy days, the road is wet and slippery, and the braking distance is longer than that on dry roads. Please increase the following distance to leave yourself time and space to deal with emergencies and avoid accidents.

In case of skidding, this is the way to deal with it: once the vehicle is out of control and skidding, release the brake immediately, turn the steering wheel slightly in the offset direction, and then step on the brake gently and brake slowly after the body direction is corrected. In case of accidents and faults on the highway, please remember: “pull over and call the police when people evacuate”.

For the above confusion, today’s central video has popularized science.

According to the report, Ms. Zou in Beijing recently installed optical fiber broadband at home. She found that the Internet was not smooth and the Wi Fi signal in some rooms was always bad. After the operator came to the door for detection, she suggested that she install another router.

According to the popular science of CCTV network, after the optical fiber enters the home, there is an optical cat. It mainly provides three functions: tens of thousands, high-definition TV and fixed telephone. Wi Fi is only one of the three functions. Compared with the router that focuses on Wi Fi, the optical cat is different. Therefore, there are many connection devices in the home and the house type is large. It is suggested to add a router outside the optical cat.

Xu Jun, senior communication line technician of China Telecom Shanghai Branch, added that different gateways have different Wi Fi capabilities. Some have 2.4GHz band, and some support 2.4GHz and 5GHz band, which can basically meet the Wi Fi coverage of single scene and small house type. However, in case of complex scenes, large coverage area and many access devices, it is recommended to add Wi Fi routers.

Xu Jun also popularized the skills of choosing a router. First, it depends on the speed of the router, which should be more than twice the incoming broadband. Second, it should choose a router with Wi Fi 6 as the wireless protocol, which can solve the problem of data congestion and delay when the router is connected with multiple devices.

Is it better to have more antennas? Xu Jun said that now many router antennas are built-in, so we should pay attention to its beam presentation, multi-user multiple output and other technologies, such as 2x2 MIMO.
