Description

Method, medium and system for monitoring the training status of smoke-generating vehicles using AR glasses

technical field

Background technique

In the field, AR glasses are used to monitor the equipment training status, especially for the high quality requirements of the smoke vehicle diagnostic personnel. The smoke vehicle diagnostic personnel often need a variety of knowledge and experience in the inspection and diagnosis of smoke vehicles. The degree of modernization is getting higher and higher, and it is more and more necessary to diagnose the training smoke-generating vehicle through command coordination; at present, the most suitable command coordination method is to realize the coordinated command between the command center and the training position through remote video.

Due to the single communication mode between the smoke vehicle position and the command center and the lack of a reliable data transmission network, the data communication between the smoke vehicle position equipment and the command center is often realized by the smoke vehicle Mesh ad hoc network; the smoke vehicle is a common A kind of outdoor smoking car, equipped with a smoke generator. At present, many smoking cars are also equipped with networking equipment. Mesh is literally translated as a mesh, and a Mesh network is also called a wireless mesh network, that is, all nodes in the network are connected to each other wirelessly to form an overall network. Traditional communication networks have fixed base stations and mobile handsets, while Mesh networks have no fixed infrastructure, and all nodes in them are dynamic. In this network, due to the limited wireless coverage, two nodes that cannot communicate directly can use other nodes to forward packets and connect to any node in the network. The basic structure of Mesh includes star structure, linear structure, ring structure, mesh structure and so on.

During the training, it is necessary to consider the convenience of coordinated command and the security of data transmission in the diagnosis process of the training smoke-generating vehicle. Directly through remote video command, it is often not possible to coordinate the command and diagnosis well, which affects the efficiency of diagnosis; there are the following technologies Problem: Due to the wireless connection between the smoking vehicles, due to the influence of the smoke range and smoke concentration from the smoking vehicles, the wireless signal transmission process will cause attenuation, causing the wireless transmission distance to be too short. As the vehicle distance increases, the power of wireless transmission will also increase, the power consumption and the risk of being intercepted will also increase, and reliable data security transmission cannot be performed.
