Method for alarming uncapping of manhole cover

Abstract

The invention discloses a method for alarming uncapping of a manhole cover. The method comprises the following steps of: mounting a manhole cover alarm on the manhole cover, and electrifying; detecting abnormal condition of the manhole cover in a detection mode of an optical fiber and methane; if uncapping does not occur, continuously detecting, and if uncapping occurs, awakening a ZigBee controller in the manhole cover alarm, reading basic information of the manhole cover, transmitting data to adjacent nodes in network by virtue of a ZigBee network, and finally transmitting data to an embedded gateway; processing data by the embedded gateway, and displaying an alarm position; sending the processed data information to a Web server provided with fixed IP in a unified way by the embedded gateway by virtue of a GPRS module and sending an alarm short message to a maintenance man, and storing the information by the Web server by virtue of a database; inquiring the manhole cover information stored by the Web server through the Internet by a municipal facility management office and a running water plant organization, recording and sending a short message to the maintenance man. The system utilizes the characteristics of the ZigBee network of wide coverage area, low power consumption and stable transmission, and automation of theft-proofing of the manhole cover is achieved.

Description

technical field [0001] The invention relates to the technical field of well cover protection, in particular to an alarm method for opening a well cover. Background technique [0002] Manhole covers on urban roads are often damaged or lost, which can form traps on the road surface and pose a danger to passing vehicles and pedestrians. The total number of all kinds of manhole covers in super-large cities across the country is more than 1 million, that of large cities is more than 800,000, and that of medium-sized cities is more than 500,000. According to statistics, the annual number of stolen manhole covers in general cities exceeds about 1% of the total amount. Potential safety hazards caused by manhole covers include: theft of manhole covers, the theft of underground electric cables through the entrance of manhole covers, affecting power supply and communication; due to the sewer not being cleared on time, siltation is caused, and the concentration of biogas formed for a l...

AI Technical Summary

Problems solved by technology

Potential safety hazards caused by manhole covers include: theft of manhole covers, the theft of underground cables through the entrance of manhole covers, affecting power supply and communication; due to the sewer not being cleared on time, siltation is caused, and the concentration of biogas formed for a long time is too high to cause poisoning, explosion and other dangerous events

[0003] The loss or damage of the manhole cover will cause large economic losses and personal casualties, so it is necessary to design a safety monitoring system to solve the above problems
