The MEC center mainly comprises operator transmission equipment, a user plane server, a firewall and the like, wherein the data storage and forwarding service is deployed on the user plane server, so that data and video information can be prevented from entering a core network and an IP network, the video forwarding is completed locally, the transmission delay is reduced, the data security is ensured, and application services such as local detection data, multi-robot interaction data, cooperative operation control and the like can be deployed on the MEC.
Further, the communication system provided by the application has the following beneficial effects:
(1) Compared with a communication mode of optical fiber + WIFI (WAPI), 5G can provide wireless high-speed communication and data transmission functions for a large number of access devices in the station through the base station without complex optical fiber access, and has the advantages of large connection, edge calculation, slice customization, safety isolation and the like.
(2) By applying the macro base station and the extended small base station, the MEC can be deployed in the base station, a highly distributed computing environment and a storage function are provided in a wireless access network, network delay can be reduced, and user experience quality can be improved. In addition, the MEC draws cloud computing and cloud storage to the edge of the network, and can be used for executing special tasks which cannot be completed in the traditional network architecture, such as application-aware performance optimization, big data analysis, distributed content caching and the like.
(3) By applying the deployment of the base station in the 5G station, 5G 'slicing' can be realized in the transformer substation to provide functional division for different application scenes of the transformer substation, for example, videos and meter photos of a high-definition intelligent monitoring system need to be transmitted back, the monitoring image quality needs to be clear enough, and the use requirement is not influenced after the total delay of tens of seconds; however, when the robot is operated and controlled through the 5G network for remote operation, the delay is required to be low enough and needs to be within tens of milliseconds, otherwise equipment damage or electric shock can be caused, and the operation safety is seriously influenced.
(4) Typical services of the 5G transformer substation, such as high-definition video, augmented reality/virtual reality, remote control, industrial internet and the like, all put higher requirements on in-station overlay network indexes. Many services in the 4G era are carried by the extra-station macro base station, and for 5G, the extra-station macro base station has greater difficulty in covering the inside and the inside of the station due to the adoption of higher frequency band deployment, and the construction cost of the equally covered extra-station base station is far higher than that of 4G; meanwhile, the traditional 4G passive distributed antenna system only supports the frequency band below 2.7GHz, and is difficult to modify and implement, high in cost and difficult to meet the 5G requirement. The adoption of the 5G macro base station and the small base station not only can be matched with the macro base station to deploy and sweep out the coverage blind area, but also can realize the operation requirements of diversification and data safety isolation through 5G slicing and MEC edge calculation.
(5) The mode that the robot carries the wireless base station is adopted, signal enhancement and multi-access point service at any position can be provided for the mobile robot of the transformer substation, the robot can receive and forward control commands of a remote control base station and a controller conveniently, and the 5G slicing function can be applied to realize the ultra-low-delay first vision video monitoring and stable control of the robot, the safe isolation and high-speed transmission of detection images and data, the low-altitude cooperative operation of an unmanned aerial vehicle and the robot and other different functions.
