I. Overview
Mobile communication services are closely related to people’s lives, and it has become an important task for mobile companies to provide users with high-quality and satisfactory services. Therefore, the comprehensive construction of base stations is very important. At present, mobile company base stations have a very wide coverage, and mobile base stations have been built in high mountains and remote villages. This has made great efforts for the signal coverage of mobile communications.But the mobile base stationmonitorIt has also become a very big problem. With the overall transformation of mobile networks, in order to improve work efficiency, all mobile base stations must be unattended. Establish a monitoring center in the mobile dispatch communication center, which can monitor and monitor the relevant data, environmental parameters, images, etc. of each base station, so as to be able to directly understand and grasp the situation of each base station in real time, and respond to the situation in time , Strengthen the maintenance and management of mobile base stations to ensure the smoothness of mobile signals and meet the needs of industry development.
The management of mobile base stations in various regions mainly has the following prominent problems: The management of mobile base stations in various regions has the following characteristics:
1. Mobile base stations are distributed throughout the city and countryside, high mountains and flat land, and complex terrain. The traditional manual inspection method can no longer meet the needs of the rapid development of mobile communication services;
2. There is a lack of professional maintenance personnel, and the level of maintenance personnel is uneven. Maintenance personnel cannot timely monitor the operating status and environment of the mobile remote base station equipment, and cannot eliminate equipment malfunctions in time;
3. The safety of alpine base stations cannot be guaranteed in time. Due to the wide distribution of base stations, the surrounding environment is complex and unattended, the security problems of the computer room appear to be more prominent, and security issues such as fire prevention, theft prevention, and waterproofing must be solved to ensure the safe operation of the equipment.
4. Theft of base station equipment is serious.
1. Solution
The mobile base station is an effective means to ensure the normal operation of the communication network, but the environment is different in different places, resulting in very low work efficiency, and a lot of time is wasted in the process of climbing and walking. It brings certain difficulties to the timely repair of mobile communications. For this reason, Guangzhou Yantong Technology Co., Ltd. has organized a group of technical personnel with technical experience in the communication industry and cutting-edge electronic technology personnel to develop a wireless video surveillance system specifically for mobile base stations, which effectively solves various disadvantages of base stations. , Directly through the mobile GPRS data network, video data can be transmitted to the streaming media server, so that the mobile base station supervision and maintenance department can timely and truly understand the environment of the base station site, effectively ensuring the normal operation of the communication network.
1) Acquisition terminal: The acquisition terminal adopts high-speed dome camera to acquire, and the acquired image is fast and clear.
2) Network: Due to the inconvenience to provide a wired network, the live video images can be transmitted to the mobile IDC’s intelligent integrated application platform for streaming media (SCCAP) or the integrated intelligent integrated application platform for streaming media installed by this unit through mobile GPRS and EDGE wireless networks in time (SCCAP), and then the mobile base station monitoring center can be directly watched through the network PC or mobile phone.
3) Monitoring terminal: Mobile phone is the most commonly used communication tool, and mobile phone monitoring, as the latest and most convenient monitoring method, is to make full use of the portability and ease of operation of mobile phones, as well as China Mobile’s ubiquitous wireless network to achieve “anytime A brand-new monitoring mode of “anywhere, free control”. The wireless video surveillance system of the mobile base station enables the field staff and leaders to observe the surveillance points immediately and clearly. It can also be viewed on a computer.
2. The structure and design principle of the system
Mobile base station wireless video monitoring system-“Mobile Eye” means that users can monitor monitoring points anytime and anywhere through mobile devices such as mobile phones, PDAs, computers, etc., and check the monitoring points clearly and accurately. During the monitoring process, you can Adjust the pan/tilt to the best monitoring angle. The “Mobile Eye” system consists of four parts: 1. On-site video capture front-end, 2. Video transmission network, 3. Streaming media intelligent integrated application platform (SCCAP) 4. Monitoring terminals such as mobile phones, computers, and TV walls. As shown below:

(1) Collection front end
Front-end monitoring equipment: through the collection of front-end equipment: high-speed dome camera to transmit the image to the streaming media intelligent integrated application platform (SCCAP), the form of access can be wireless, the camera can be a pan-tilt or non-pan-tilt device; outdoors, Taking into account the different weather, temperature, light and other complex environmental conditions, the camera with infrared can be directly connected to the network;
(2) Video transmission network
Both wireless and wired transmission can be implemented. The wired method is an Internet network platform that can support various Internet access technologies, such as ADSL, Ethernet, and dedicated lines. It makes full use of the economic and convenient features of the Internet. The wireless method is implemented through the wireless platform of China Mobile, and the network coverage rate is high.
(3) Streaming Media Intelligent Integrated Application Platform (SCCAP)
The platform has functions such as authentication, management, operation, and storage, and supports overall monitoring of multiple users, multiple scopes, multiple applications, and multiple distributions. Through the software and hardware equipment of this platform, the following main functions can be easily realized:
Add, modify, delete, query and other user file management;
In order to provide a safer monitoring guarantee, users are required to perform identity authentication before entering the system;
Implement different operation authorizations for users with different identities;
Video storage
Video playback;
(4) Monitoring terminal
“Mobile Eye” supports multiple forms of monitoring terminals. Users can monitor anytime and anywhere through mobile devices such as mobile phones, PDAs, and computers, or centrally monitor through PCs, or traditional devices such as TV walls and projections.
3. Main features of the system
Mobility: The application of mobile GPRS and EDGE wireless networks can achieve a smooth high-definition image effect of 5-20 frames per second, without network wiring and antenna erection;.
The system covers a wide range: it can be applied across the country, including remote mountainous areas covered by other operators’ wireless networks;
Image compression algorithm: adopts the latest and high compression H.264 video compression algorithm;
Network image transmission: low network resource occupancy, high-quality and smooth image transmission under low-bandwidth conditions;
Support dynamic IP: adopt dynamic IP resolution technology to automatically resolve IP addresses allocated by the Internet;
Networking: Through mobile GPRS, EDGE wireless network and Internet network, it can truly realize monitoring at any time, from any place, and on any site;
Easy to use, simple to operate and manage: you can install client software on PCs and mobile phones, or you can directly monitor and manage remotely through WEB, with a graphical interface;
Complete monitoring and management functions: The system provides users with flexible monitoring screen selection, preset and lens patrol, as well as functions such as image capture, video and video playback, alarm and alarm linkage;
Information security: make full use of technologies such as network tunnels, firewalls/VPNs, encryption locks, authority management, security authentication, real-time clocks, etc., to ensure that the monitoring system and video data are not used or destroyed by unauthorized use;
Powerful management platform: Distributed and hierarchical management, users can monitor, manage, view, and command real-time management targets in real-time without being restricted by time and space.
