| Modern integrated command center,because of its collection of data mining, decision support, communication and command-in-one, a large number of applications in the public safety, transportation, energy and mines, health, urban management and other industries. Audio and video systems, commanding officers the most direct access to information sources is a key structure in the command center building. The same time, due to the command center of the unique functional requirements, the audio and video system can not simply equal to the design and construction of other audio and video systems, program design and construction according to their own characteristics.By the special requirements of the analysis of the command center audio and video system, targeted to design a set of command center audio and video solutions, and strive to make it have widespread applicability, interface specification, cost control, convenient operation, easy maintenance features. Construction risk control in the design and construction contract changes, device compatibility, function, able to meet the full the command center audio and video system is flexible, fast, stable signal switch, expansion in the latter part of the operation and maintenance solution to avoid duplication of investment.This paper proposes a model of the flow of information in the command center, summarizes the various interface types, and discuss the problems in the construction summarized on the process, the need to consider the risk control and maintenance methods described provide theoretical guidance for the construction of the command center, modular switching unit as the core design concept in the design process, summarized the commonly used ports formula, new construction principles and recommendations, trying to form a common pattern and specification for the actual construction and operation and maintenance to avoid the detours provides a useful reference. |
