The nation's first scale to use TD to monitor traffic in real time
The main means of transportation for traveling in Nanning is the bus, so the management of bus passenger transport is also increasingly valued. According to the reporter's field visit, Guangxi Mobile's "bus video monitoring platform" based on the TD network HSUPA new technology application has been widely used in bus travel management to meet the needs of "real-time" and "live" control of vehicles on the road, and truly achieve The management effect of "vehicles run thousands of miles away, supervision is realized by remote control".
The reporter saw at Nanning Dongdong Station that in less than 10 seconds, the picture of a bus No. 6 driving near Jinhu Square appeared on the display screen. The colorful picture not only showed the position of the exit door, but also The situation and the road conditions in front of the vehicle are also clear, especially the picture of the front door position, not only can clearly capture the face picture of the passenger on the bus and the coin insertion situation, even the driver's operation is also clear, turn on the microphone, the sound inside the car Clearly transmitted to the command center through the platform.
The person in charge of the on-site bus said that the situation on the bus can be monitored in the command center in real time. This function is derived from the real-time video transmission monitoring platform based on the mobile TD-SCDMA wireless network HSUPA technology. The average rate of video upstream transmission can be maintained at about 300kbps, which basically realizes the smooth and stable transmission of sound and pictures in real time to the command center.
In addition, the bus video surveillance project has also integrated the Internet of Things M2M application with cloud computing. A bus video cloud platform has been built in the IDC machine room of Guangxi Mobile. The bus video data is transmitted and stored in the bus video cloud computing platform in real time to achieve video surveillance data. With a storage time of more than 1 year, the bus company can use the monitoring client to realize real-time video image retrieval through the point-to-point dedicated line, and can perform related management operations on the data.
So, how does such a monitoring platform help users and bus companies? The person in charge of Guangxi Mobile-related projects told reporters that images such as the interior of the car, front door, rear door, road conditions in front of the car, driver operation, and coin-operated machines can be transmitted to the background management system in real time through the 3G wireless network. The company uses the monitoring client to realize the real-time video image retrieval through the point-to-point dedicated line, so as to realize the management of public transportation, reduce the occurrence of accidents, and improve the sense of security of citizens taking the bus. The bus companies can use real-time remote monitoring to promptly notify and correct drivers' speeding, overloading, and fatigue driving, reducing the incidence of accidents.
According to Zhang Chuang, deputy general manager of the Nanning Group Customer Branch of China Mobile Guangxi Corporation, bus video surveillance has been put into construction as one of the seven political and legal livelihood projects for the private sector in the Nanning Municipal Government in 2011. "Vehicle video monitoring platform" has reached as many as 500 bus vehicles, and Nanning has therefore become the first city in the country to adopt TD-SCDM's HSUPA wireless network technology to carry bus video for real-time monitoring.
At present, the platform's data processing capability can ensure that the 2770 buses in the city still provide normal services after installing the 3G video surveillance system. In the future, the bus video surveillance system will also be extended to the application of taxis, passenger buses, and freight vehicles. After TD-LTE coverage, data transmission will be further improved, and the smoothness and clarity of the picture will be higher.
The 4G MiFi and 5G MiFi are portable Wireless Router devices that convert 4G or 5G network signals into Wi-Fi signals, making it easy for users to connect to the Internet from anywhere. The following is a detailed description of the advantages of 4G MiFi and 5G MiFi.
1. Faster network speed: 4G MiFi and 5G MiFi are faster than traditional 3G networks. 4G networks typically offer speeds several times faster than 3G, and 5G networks are a huge breakthrough in terms of speed. This means users can download and upload files, stream videos, play online games and more faster.
2. More stable connection: 4G MiFi and 5G MiFi provide a more stable connection, reducing the possibility of disconnections and dropped calls. This is important for users who need a stable Internet connection, especially when doing important video conferencing, online education or telecommuting.
3. Greater coverage: 4G MiFi and 5G MiFi have wider coverage than traditional Wi-Fi routers and can cover a larger area. This is useful for users who need to use the Internet outdoors or where there is no fixed Internet connection, such as camping, traveling, or in rural areas.
4. More connected devices: 4G MiFi and 5G MiFi usually support multiple devices to connect at the same time, which can meet the needs of multiple users. This is very useful for families, small offices, or team work where you can easily share an Internet connection.
5. Portability: 4G MiFi and 5G MiFi are very portable and can be carried everywhere. They typically have a compact design and light weight that can fit in a pocket or bag. This makes it easy for users to use the Internet from anywhere, without having to find a Wi-Fi hotspot or rely on a wired network connection.
6. Easy to use: 4G MiFi and 5G MiFi are very simple to set up and use. Users simply insert the SIM card, turn on the device, and automatically connect to the Internet. Some devices also offer user-friendly management interfaces that make it easy for users to view device status, manage connected devices, and set network security.
7. Higher security: 4G MiFi and 5G MiFi usually have built-in security features to protect users' network security. They support WPA2 encryption and firewall features that prevent unauthorized users from accessing devices and networks.
8. Sharing capabilities: Some 4G MiFi and 5G MiFi devices also have sharing capabilities that allow you to share files and media via a USB port or an SD card slot. This is useful for users who need to share files between multiple devices, such as sharing photos and videos while traveling.
In summary, the 4G MiFi and 5G MiFi are portable wireless router devices that can convert 4G or 5G network signals into Wi-Fi signals. They offer advantages such as faster Internet speeds, more stable connections, greater coverage, more connected devices, portability, ease of use, increased security and sharing capabilities. This allows users to easily connect to the Internet anytime, anywhere, and meet various network needs.
