Description

MANAGEMENT AND CONTROL SYSTEM OF PIPE}

The present invention relates to a system for managing and controlling pipelines such as water pipes, gas pipes, oil pipelines, etc. More specifically, it manages and controls each branch pipe branched from the main pipe and the main pipe through which fluid or gas is introduced and supplied. It relates to the management and control system of the pipeline to do.

In general, the waterworks business is intensively invested in expansion projects to meet the water supply of customers, replacement of old pipes, regeneration, meter replacement, etc., but leak rates increase due to old water supply and drainage pipes and poor maintenance of facilities, and stagnant water flow rates. It is becoming.

Accordingly, in recent years, waterworks facility management design service has been operating in manual form of waterworks facilities based on document types such as basic and detailed design of wide area waterworks waterworks design and drainage basin design and drawings of waterworks management ledger.

However, it is known as a big problem that it is not possible to quickly respond to the operation plan, maintenance, demand forecasting, and leak recovery of waterworks facilities due to inefficient problems caused by manual work. Moreover, it leads to the main building and connects to each building or house. It is not possible to confirm whether there is an abnormality in water supply facilities, such as water flow and water pressure, in relation to the condition of the branch pipe.

Furthermore, as the water purification plant, which had to filter clear water, as in the last red tap water incident in Incheon, rapidly increased the flow rate through the valve opening, it supplied red tap water containing foreign substances to each household.

Accordingly, even if the supply of water containing foreign substances was performed, if the proper opening and closing operation was performed through the control of the main pipe or branch pipe, there would be no problem that water containing impurities was supplied to each household. Therefore, it is urgent to introduce an appropriate operating system to take more effective and prompt action on the branch.

And the same goes for gas piping as well as for water pipes.

The use of city gas is currently increasing for home heating and cooking, and plumbing facilities are required for its smooth supply. Accordingly, the main pipe is buried, and branch pipes installed in each building and house are connected to and supplied to the main pipe. The gas branch pipe is often a gas pipe corresponding to a user's private property, and is often difficult to manage. There was a problem that it was difficult to grasp the current status of the buried city gas pipeline.

Moreover, it is the most reliable method to check the gas leakage and the condition of the piping directly with the naked eye, but it is impossible to check this for the buried type. Therefore, it is urgent to introduce an operating system that effectively prevents accidents by effectively blocking the pipeline of dangerous elements due to aging gas leakage, earthquake, and pressure changes.
