Saudi ArabiaDiscussion on Summer Construction Method of Concrete for North-South Railway Project?

1. In order to solve the problem of lack of local stone materials in Saudi Arabia, the project department boldly proposed to change the embankment protection and culvert inlet and outlet paving from slurry stone to reinforced concrete, which not only ensured the construction schedule, but also greatly reduced the cost.

Where is the wireless charging for Line 15

1, door side. Shanghai Metro Line 15 is located in the high-tech area, the design combines high-tech elements, smart wireless charging seat next to the door.Shanghai Metro Line 15, known as the Western Corridor, is an important north-south line under construction in Shanghai's rail transit network.

2, the entrance. Shanghai Metro Line 15, the 17th subway line in Shanghai, China, will be opened on January 23, 2021, with a logo color of champagne gold. The subway has a shared charging bank, located at the entrance of the station, and users can scan the code to access it.

3. The regional train of Line No. 3 is equipped with a charging station that fits people's travel needs. The edge around the charging station is raised, and the middle is a wireless charging areaRate, wireless charging standard. Based on the single green area, it should be a single module configuration. At present, the mainstream iPhone, Android mobile phones and Bluetooth headsets on the market are compatible with the Qi wireless charging standard, and it is speculated that this area will also be compatible with Qi devices.

How does wireless charging work?

1, mobile phone wireless charging technology is completely without the use of wires, the use of magnets for mobile phone charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transmit electricity in the air between the charger and the phoneThe coil and capacitor form a resonance between the charger and the mobile phone to achieve efficient transmission of electrical energy.

2, wireless charging methods are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.

3, radio wave charging is different from the above two charging methods. tongA radio wave transmitting device is configured in the power supply and a radio wave receiving device is configured in the power receiver to transmit power using DC voltage output and input. Its advantage is that the transmission interval is medium, the transmission speed is fast, the disadvantage is that the stability and security are low, and it requires a certain cost to invest in research and development.

BYD, Red flag lead! 2023 Shanghai Auto Show Preview: New energy car inventory

The Shanghai Auto Show will kick off on April 18 as the country's top three carsOne of the exhibitions, the first new car at the Shanghai Auto Show is naturally indispensable.

Although the Hongqi H6, like the new Hongqi H5, is a medium-sized sedan, but the Hongqi H6 design is significantly younger, is a new model for young people. The arrival of Red Flag H6, let us see the positive side of red flag change. As for the market performance of Hongqi H6, it depends on the price of the new car and the acceptance of the Red Flag brand by young people. Wei brand new MPV Great Wall official revealed that Wei brand new MPV will be released in 2023 Shanghai Auto Show.

New energy has become the normal car companies without new energy, it is difficult to set off waves in the market. At this Shanghai Auto Show, new energy models and related technologies have inadvertently stood on the "C position". Whether it is a joint venture brand or an independent brand, the prominent position of the booth is basically occupied by new energy models, and fuel vehicles are often at the edge of the booth. ▲ Honda Accord plug-in models Honda, for example, in the hybrid models become the main force.

At the same time, since entering 2023
