Utility tunnel monitoring and early warning system

Abstract

The invention provides a utility tunnel monitoring and early warning system, which comprises a physical perception layer, an integrated application layer and a network transmission layer, wherein the physical perception layer comprises a plurality of front-end perception devices and a gateway node in communication connection with each front-end perception device; the front-end perception device is set to acquire each piece of perception information in the utility tunnel; the gateway node is set to upload the perception information acquired by the front-end perception device to the network transmission layer; the network transmission layer comprises a backbone network node which is set to upload the perception information uploaded by the gateway node to the integrated application layer; the integrated application layer comprises a plurality of control terminals which are set to carry out operation processing on the perception information uploaded by the network transmission layer and provide corresponding application service according to a processing result. Various conditions in the utility tunnel can be monitored in a real-time and online mode, each relevant department can quickly take effective measures, loss caused by error reporting or missed reporting is avoided, the reliability is high, the capital construction input is little, and the maintenance and the operation are convenient and quick.

Description

technical field [0001] The invention relates to the field of sensing technology, in particular to a monitoring and early warning system for a comprehensive utility gallery. Background technique [0002] The comprehensive pipe gallery refers to the public tunnel where municipal pipelines such as water supply, rainwater, sewage, reclaimed water, natural gas, electricity, and communication are laid in a concentrated manner. Urban infrastructure engineering has become an important part of urban infrastructure. The construction of comprehensive pipe corridors in my country has just started. Since 2013, a series of policies and regulations have been issued, requiring the steady promotion of the construction of urban underground comprehensive pipe corridors. In August 2015, the State Council promulgated the "Promotion of Urban Underground Comprehensive Pipe Gallery Construction "Guiding Opinions", the comprehensive pipe gallery is regarded as a livelihood project supported by the s...

AI Technical Summary

Problems solved by technology

[0003] At present, the general design of underground comprehensive pipe corridors at home and abroad is relatively conservative, and there are many problems: there are pipelines for transporting special media such as water, electricity and heat in the pipe corridor, and there are potential safety hazards of medium leakage; the comprehensive pipe corridor itself is equipped with ventilation, lighting, power supply, There are a large number of equipment maintenance and management problems in fire protection, drainage, identification, monitoring, alarm and other systems; the pipe gallery system has single or insufficient functions, and the monitoring and management are not intelligent enough; drainage, sewage and other functional pipelines cannot be integrated, occupying The underground space resources are large; the construction method is outdated, and the construction cost is high; there is no expansion function reserved for the future development of the city

[0004] At present, the publicly reported integrated pipeline corridor monitoring and early warning system mainly has the following characteristics: First, the monitoring terminal uses public networks such as GPRS / 3G / 4G for communication, and each sensor must be equipped with a SIM card, which requires a large cost investment and high operating traffic costs

Second, the monitoring terminal is implemented using short-distance interconnection technologies such as Zigbee, and the line-of-sight distance is generally short. At the same time, the environment in the pipe gallery is complex, resulting in a closer wireless signal transmission distance, which requires a large number of monitoring nodes, resulting in huge investment in municipal infrastructure.

Third, the technical means are single, and various technical means are not effectively used together. It mainly relies on the monitoring and alarm system of the pipe gallery itself, and the work efficiency is low. Especially when an equipment failure occurs in the pipe gallery, it is necessary to search for analysis drawings and read equipment Parameter information, comprehensive consideration of the connection between upstream and downstream related equipment, and combined with relevant experience can try to solve the equipment failure problem on site. There are also shortcomings such as poor interaction between the work site and the control center, outdated daily maintenance mode, and manual office work.

Fourth, due to the lack of unified technical specification guidance and application, the quality of these established systems is often mixed, the interconnection between systems is poor, data exchange is difficult to carry out, parameters and interface design are often not standardized, equipment is not compatible, and it is difficult for comprehensive The safety management of the pipe gallery brings hidden dangers

With the development and progress of science and technology, people have successively added a series of auxiliary systems to urban comprehensive utility corridors, such as automatic fire extinguishing systems, ventilation systems, video surveillance systems, environmental monitoring systems, etc., but most of these information systems only have monitoring functions, and It cannot be intelligently controlled and managed. Although it can solve the hidden safety hazards of some urban pipe networks, most of them are operated and operated independently, which is not conducive to information linkage and rapid response, and brings problems such as urban safety, environmental protection, and high management costs.
