Inductive multidimensional sensor and monitoring method for subway interval protection airtight partition door

Abstract

The invention discloses an inductive multidimensional sensor and monitoring method for a subway interval protection airtight partition door. The inductive multidimensional sensor comprises a door leaf opening and closing angle calculation and monitoring module, a door plate flatness monitoring and analysis module, a fitting degree monitoring module, a data receiving and sending analysis module and a networking breakpoint detection module. The door leaf real-time opening and closing angles and time, the door leaf rotating time and rotating acceleration, and the door leaf axial offset angle and radial offset angle of the subway interval protection airtight partition door can be recorded. By presetting the specification (standard) requirements in a data analysis and processing module, performance such as the position and door leaf deformation of the subway interval protection airtight partition door is online quickly and accurately detected, and parameters obtained through monitoring are uploaded to a subway BAS or a detection system special for protection equipment, the system obtains data through the sensor to conduct full operation management and control on the protection equipment, and thus the safety of subway operation and the good protection performance of wartime equipment are guaranteed.

Description

technical field [0001] The invention relates to the field of monitoring and maintenance management of the state of a protective airtight partition door in a subway section, the opening angle of a door leaf, the degree of fit between a door leaf and a door frame, the degree of fit between door leaves, the judgment of the flatness of a door panel, and the detection of equipment health performance. Background technique [0002] As a city's underground transportation artery, the subway project is not only a large-scale urban transportation infrastructure project, but also a major urban civil air defense project. Once the war comes, it will build the civil air defense system of the whole city together with other civil air defense facilities in the city. The subway civil air defense project is generally composed of several protection units, usually one station and one section as a protection unit, and the subway section protection airtight partition door is divided protection An i...

Problems solved by technology

At present, the monitoring device generally uses a contact photoelectric switch. Due to the limitation of the function of the device, it can only collect the switch value, and it is either on or off. In actual use, the vibration of the subway often causes the contact point to loosen and come off. Dust accumulation will affect the correctness of data collection, and there will be false positives, missed negatives, dropped calls, etc. At the same time, after the BAS system receives an abnormal alarm from the equipment, it will trigger the subway outage detection and eliminate false positives.
