The Smart Manhole Pipeline Management System using USN is a U-City-based service that directly monitors the availability and availability of pipelines per route section when installing optical cable / telecommunication cable through the management of the status of use of Smart Manhole Management System, It is possible to construct a low-cost, high-efficiency installation.
Description
The present invention relates to a smart manhole management system and method using USN (Ubiquitous Sensor Networks), and more particularly, to a manhole information system and an underground facility management information system We developed a code scheme for NFC tags, designed a mechanism for mounting NFC tags on the manhole cover, developed a Smart Manhole App for NFC communication in mobile terminals with NFC communication functions, Or NFC tags attached to facility equipment of pipelines, SW developed to search and input information related to manholes, pipelines, and communication facilities, and to provide facilities for communication manholes and pipelines, cables, enclosures, and underground facilities Systematically manages information and maintenance histories, and optimally manages communication manholes and communication management DBs to establish new communication lines. It provides an estimate simulator tongsingwan, to a smart manhole management system and method using a USN, for providing the position information of the manhole in GIS map in the mobile terminal.
Currently, hundreds of thousands of communication manholes and communication lines are installed nationwide, and many communication facilities such as national, local governments and telecommunication companies buried various communication facilities and underground joints in an underground space of 3m ~ 5m underground. Various accidents and disasters are increasing rapidly because they can not accurately grasp the location and condition.
Especially, in the case of communication manhole and communication line, since the standard of the connected pipeline and the pipeline usage information are not sufficiently DB, it is dependent on the experience of a specific person such as a field worker or a worker, so that inaccurate and ineffective management is performed.
Therefore, it is necessary to construct a system that can manage the communication manhole and communication line installed in the whole country.
Currently, hundreds of thousands of communication manholes and communication lines are installed nationwide. In the case of old cities, not only are electric power and communication facilities installed on the ground in order to improve the urban environment, but also in the case of ubiquitous cities, new cities and redevelopment districts Is constructed with 100% underground communication lines.
In addition, due to the continuous increase of communication demand, various communication facilities and underground culverts buried in the underground (underground) in numerous institutions such as national, local governments, and telecommunication companies are mostly located in the underground space of 3m ~ .
Because of this, the location of underground telecommunication facilities can not be precisely identified, and various accidents are rapidly increasing.
Underground communication facilities are not only social infrastructures but also infrastructure facilities of information society. Therefore, various accidents and disasters related to underground facilities directly cause material and physical damage, and cause economic damage to the people.
Also, underground facilities often need to be replaced, maintained, and repaired, but there is a difficulty in not being able to grasp the location and status of the facility information.
In case of telecommunication manhole or communication line installed for installation of underground optical cable, the standard of the connected pipeline and the pipeline usage information are not sufficiently databaseed, so that they can depend on the experience of a specific person such as a field worker or a worker, , And when separate personnel work, inaccurate and inefficient management is being made.
The manhole is a hole that allows people to go out for the purpose of inspecting, repairing or cleaning underground facilities such as sewage pipes, water pipes, wiring and so on. Conventionally, the information of underground objects for manholes has been managed as separate documents .
However, due to the urban development, not only the ground facilities but also the facilities buried underground are complicated. Therefore, a lot of manpower is needed for the maintenance of the facilities and information management, and the document management may lose or damage the data.
In addition, it is not only impossible to confirm the site condition when foreign matter such as water enters the inside of the manhole, but also it takes much time to check the position of the connection arm and the line section for repairing optical fiber when an emergency such as a disconnection accident occurs, There are direct and indirect costs incurred due to network disturbances.
The existing management system, which relies solely on the memory of the operator, can not actively cope with various changes in the environment such as communication manhole, communication cable installation, optical cable installation and replacement, I have a problem.
Document manhole management and communication facility management are inefficient and costly to operate, so it is necessary to streamline the construction of information systems using ICT technology.
Ubiquitous technology, which is an information communication environment in which a user can freely access a network regardless of a network or a computer, is required to be improved for maintenance and information management of many facilities.
It is necessary to improve the problems caused by relying only on the memory of the current worker and manhole management by hand by using ICT technology.
For this reason, it is necessary to develop a manhole and pipeline management system using USN (Ubiquitous Sensor Networks).
Some institutions are managing facilities by dedicated terminals, but they are limited to cost issues.
1. Domestic and Foreign Technology
1.1 Domestic Technology

IHS expects 2014 shipments to grow by more than 50% over last year to 416 million.
Of the 1.5 billion mobile phones shipped in 2013, 18.2% supported NFC technology, and by 2018, this proportion is expected to surge to 64%.
The number of NFC-enabled handsets distributed in Korea is estimated to reach more than 15 million units as of April 2013, accounting for 35% of all smartphones, and including handsets equipped with a USIM (Universal Subscriber Identity Module) , Which accounts for a majority of all smartphones.
With the exception of the Apple iPhone, most smartphones released after the Samsung Galaxy S2 support NFC.
(2) RFID technology status
Currently, RFID is used in domestic and overseas to manage waterworks and sewage manholes or underground facilities.
In particular, the Seoul Metropolitan Government has been using the RFID to manage waterworks in the city since 2009, and many local governments are also using RFID to locate underground facilities, , Facility information inquiry, inspection contents input, and so on.
However, since the management system using the RFID continuously uses the data input to the RFID chip without any modification and targets the facilities with little fluctuation of the management object, the communication manhole, in which the optical cable is newly installed or replaced, There is a problem that it is difficult to apply an existing system using RFID to a communication terminal or a communication terminal.
- In October 2008, the Ministry of Public Administration and Security selected 'U-City Service Standard Model Development and Demonstration Project', which was conducted to strengthen regional competitiveness.
- The facilities integrated management system uses mobile, RFID, etc. for various facilities of 100,000 kinds such as welfare facilities, cultural sports facilities, local facilities, greenery facilities, and road traffic facilities that were individually managed by each department in the meantime. And systematically and comprehensively manages the entire process from generation to disposal.

- In 2009, the Ministry of Food, Agriculture, Forestry and Fisheries has invested 1,638 million won to supply 32.7 million RFID tags and 128 RFID tag issuers to 53 quarantine stations.
(3) QR code
ㅇ QR code recognition technology by mobile terminal
The QR (Quick Response) code is a type of 2D bar code that improves on existing bar codes, and has been widely used in Japan since it was developed by Denso Corporation in the mid-90s.
A one-dimensional barcode stores about 20 characters of information, while a QR code that represents information in a black and white plaid pattern has an advantage of being able to hold 1700 characters of Korean characters or 8000 characters of numbers, thus being highly usable.
The QR code has been adopted as an international standard and can be used free of charge with the opening of the license.
In recent years, all smartphones have been equipped with the function of recognizing QR codes by using cameras, and they are activated in areas such as distribution and publicity. QR codes are installed in civil service such as public bills and are also used for direct use as information service sites.
Fig. 2 is a photograph showing a use case of the QR code.
ㅇ In order to recognize the QR code accurately, the camera lens position and angle must be appropriate and appropriate light must be present.
Since the QR code is an image type code, there is a problem that it is mistaken when it is damaged unlike the RFID tag or the NFC tag. Therefore, the QR code is limited to applications requiring high reliability such as infrastructure management.
Fig. 3 is a photograph showing an example of QR code erroneous operation.
(4) USN utilization technology status (comprehensive)
USN, which is easy to input and output data, is widely used in electronic products such as smart printers and smart rice cookers, electronic wallets, and electronic tickets, but systems and products for facility management are staying at the test service level in some institutions or organizations In particular, there is no system or product for communication manhole and communication line which are targeted in this project.
Therefore, it is expected that the facility management system utilizing the USN, which is easy to input and output data, is in the early stage in the domestic and overseas markets, and that a positive business environment will be created in the future due to changes in environment such as development of related technologies and expansion of smart cities. do.
