Alarm Method of Communication Intelligent Manhole Cover Based on Multiple Event Fusion

Abstract

Communication intelligent manhole cover (CIMC) can effectively, accurately and in real time monitor the status change of communication manhole cover and helps protect the safety of communication pipeline and the comprehensive utilization of pipeline resources. The traditional monitoring method often leads to frequent false alarms due to the complex working environment of manhole cover and the random error of sensor. In terms of the equipment status signals generated by the CIMC terminal, a new alarm method of CIMC with multiple event fusion in this paper via jointing analysis of multi-sensor status signals is proposed on the basis of abnormal alarm events definition. The experimental result shows that the proposed CIMC alarm method by means of multiple sensor signals in this paper can not only make up for the defect that it is difficult to fully reflect the real state of manhole cover by a single sensor, but also reduces the false alarm rate caused by the random error of sensor and CIMC system. It has better practicability for the intelligent management of manhole cover and be conducive to the construction of intelligent transportation and smart city.
