The Study on Standardization Specification Total Supervision System of Urban Transit

초록

The numbers of surveillance cameras and sensors which are used in the Urban Transit lead to more than thousands in each operating agency and the numbers of those are increasing. The cameras and sensors are currently installed or plan to be installed in the EMU as well as facilities within stations. The more safety requirements of Urban Transit increase, the more such safety facilities cannot but increase. However, until now, there is no scheme which efficiently can manage safety facilities such as cameras and sensors. We still do not get off from a passive monitoring system depending on the CCTV, and with all sorts of sensors perform functions independently, there are limits to redundant investment and synthetic judgments for emergencies. It also can bring about problems like compatibility and extensibility between a new safety system and an existing system. In such the central control center we have many difficulties in conducting a comprehensive decision and responding immediately when the situation. There lacks of compatibility with the existing facilities and brings about redundancy in function and redundant investment as new facilities are installed and managed independently. To solve these problems, safety devices like all kinds of sensors and cameras, which are currently being installed, manage comprehensively and it is also required to introduction to the intelligent Supervision system. We also should propose structures and standard norms of standardized monitoring system in the whole Urban Railways sections including rolling stocks for avoiding redundant investment and for securing compatibility and extensibility on facilities.
