Description

Multi-channel communication equipment communication situation real-time presentation method Technical Field The invention relates to the fields of multi-channel communication technology and data management, in particular to a real-time sensing, data management and visual presentation method of a communication situation of multi-channel communication equipment, which is applied to operation and maintenance monitoring, situation management and control and decision support scenes of a multi-channel communication system in key fields such as intelligent traffic, emergency command and the like. Background In modern communication networks, multichannel communication devices have become a core infrastructure supporting data transmission in key fields such as intelligent transportation, emergency command and the like. The device generally integrates a plurality of channel modules such as short wave communication, satellite communication, area wide communication, wired communication and the like, can dynamically switch communication links according to scene requirements, and realizes all-weather data interaction in a heterogeneous network environment. However, the channel diversity, link dynamics, and complexity of the application scenario of the multi-channel communication device make it more difficult to present the communication situation, and thus an efficient situation awareness and data processing system needs to be constructed. Currently, the multi-channel communication equipment communication situation presenting method is mainly developed around three core links of link state acquisition, data transmission and visual display. In the aspect of link state acquisition, the prior related technology mostly adopts a periodic sampling mode, and key parameters such as channel bandwidth, signal to noise ratio, connection stability and the like are acquired through modules such as a signal intensity detector, an error rate analyzer and the like which are arranged in equipment, so that basic data support is provided for situation assessment. In the data transmission link, an architecture combining edge node preprocessing and cloud aggregation is adopted, and the edge node performs noise reduction and filtering on the acquired data and then transmits the acquired data to the cloud, so that the data transmission pressure is reduced. In the aspect of visual display, the related art is mostly based on static charts (such as line diagrams and bar charts) or simple topological diagrams, presents equipment connection relations and key parameter change trends, displays equipment connection states through the topological diagrams, and displays channel performance indexes in real time by combining parameter panels. Although the prior related art can realize the basic presentation of the communication situation of the multi-channel communication equipment, the following significant disadvantages still exist in practical application: (1) Insufficient data governance leads to a situation with lower accuracy. The parallel operation of multiple modules of the multi-channel communication device can generate massive heterogeneous data, including channel parameter data, device state data, environment interference data and the like, and the data formats, sampling frequencies and precision of different channels have obvious differences. The prior art lacks a dynamic adaptive data management mechanism, only adopts a fixed cleaning rule and a data fusion algorithm, and cannot cope with the interference caused by data heterogeneity, so that the deviation exists between the acquired data and the actual communication state of the equipment, and the situation evaluation accuracy is further affected. (2) The static diagram presentation mode cannot adapt to dynamic situation requirements. In the prior art, static charts such as line charts, bar charts and the like and simple topological charts are adopted to present situation, and the characteristics of dynamic switching and state real-time fluctuation of a multi-channel communication link are not matched, on one hand, the static charts are difficult to intuitively present the instantaneous change and dynamic association of the channel state, if continuous fluctuation of bandwidth and signal to noise ratio in the link switching process cannot be presented in real time, the change trend can be reflected only through discrete data points, so that situation dynamic expression is insufficient, on the other hand, interactivity and dynamic updating capability are not available, when new equipment access, channel faults and other scenes occur, chart contents cannot be updated rapidly, change nodes are displayed in a highlighting mode, operation and maintenance personnel can acquire the latest situation only by manually refreshing or switching the views, and real-time control of the dynamic scenes is affected. (3) Heterogeneous scenes are poorly adaptable. The hardware configuration of different mobile
