Abstract

The present invention relates to a piezoelectric film sensor-based manhole cover deformation monitoring system. The piezoelectric film sensor-based manhole cover deformation monitoring system includes a PVDF piezoelectric film sensor, a signal processing module, an A/D converter, a single-chip microcomputer and a communication module; the PVDF piezoelectric film sensor is spirally arranged at the bottom of a manhole cover; the wire of the PVDF piezoelectric film sensor is led out and is connected with the input end of the signal processing module; the output end of the signal processing module is connected with the input end of the A/D converter; the output end of the A/D converter is connected with the input end of the single-chip microcomputer; and the output end of the single-chip microcomputer is connected with the input end of the communication module. The piezoelectric film sensor-based manhole cover deformation monitoring system of the invention has the advantages of convenient installation, flexible operation and high monitoring sensitivity, and can timely feed back the work condition of the manhole cover to a pipeline network operator and can assist in effectively protecting the travel safety of citizens.

Description

technical field [0001] The invention relates to the field of drainage pipe network management, in particular to a monitoring system for manhole cover damage and deformation monitoring. Background technique [0002] With the acceleration of urbanization and the expansion of urban areas, the construction of municipal public facilities has developed rapidly. The pipe network shuttles intricately under the city. And because the pipeline network in most cities in my country is about to enter an aging period, the health problems of the operation of urban underground lifelines will become more and more serious; especially damaged and deformed manhole covers pose a great threat to the safety of people's daily travel. At present, the monitoring technology for manhole cover anti-theft has been relatively perfect in China, but the monitoring of manhole cover damage and deformation is still in a blank stage; therefore, how to effectively monitor the structure of manhole cover is an imp...
