Abstract: Audio and video monitoring systems play an important role in the safety production of railway enterprises. The professional departments of railway enterprise build or rent many audio and video monitoring systems to meet their needs. With the repeated construction and independent use of more and more audio and video monitoring systems, many problems, such as low system utilization, complex technical standards, diversified application software, difficulty in information sharing, uncontrollable security, have become increasingly prominent. Therefore, based on an extensive investigation of the construction and application of the existing audio and video monitoring systems, the application requirements of audio and video monitoring resources are thoroughly discussed and the audio and video monitoring integrated platform scheme for railway enterprises is proposed. Aiming at the goal of "a set of standards, a platform, and a special network", the deep integration and effective fusion of the existing audio and video monitoring resources of railway enterprises can be achieved, thus greatly improving the utilization rate of audio and video monitoring resources while fully ensuring the network security of these existing systems. Meanwhile, the unified operation and maintenance management and standardized management of technical records of the audio and video monitoring equipment are realized, which can provide an accurate basis for the decision on future renovation or expansion of audio and video monitoring systems, and help to change the adverse situation of decentralized construction and repeated investment of audio and video monitoring resources in the past.
