Description
Technical field
It is the present invention relates to a kind of fuel gas pipeline leakage emergency system and method, more particularly to a kind of based on subsidiary conduit
Pipe gallery fuel gas pipeline leakage emergency system and method.
Background technology
City Buried Pipeline is the important component part of urban infrastructure, and current China's underground utilities are intricate, respectively
Department is developed accordingly according to needed for oneself, causes underground utilities heavy clutter, have impact on normal traffic and the city in city
Hold city's looks.Therefore, country puts into effect relevant policies, and all of underground utilities are focused in piping lane to manage.
Due to the particularity of some location landform, failure is susceptible to, when these local gas pipelines go wrong, is led to
Normal management method is that the pipeline that will be associated with the pipeline is all cut off, and suspends and uses, and this will cause in a very long time
Neighbouring resident cannot normally use combustion gas, the life to resident to bring very big inconvenience.Therefore, the spy for easily breaking down
Take adequate measures and method in different location, it appears particularly important.
At present, when the existing pipeline when in piping lane gas pipeline has leakage, general is control exhaust fan by the way of
By the gas outlet pipe road in pipeline, while being keeped in repair in pipeline by maintainer, the method can will leak out in time
Gas outlet pipe road, and notify that maintainer carries out pipeline maintenance, but can not solve the problems, such as pipe leakage in time in time, only
Energy personnel to be repaired can provide a user with day steam after being repaired.
The content of the invention
In the presence of invention is in order to solve the problems, such as prior art, here provide firstly a kind of based on the comprehensive of subsidiary conduit
Piping lane fuel gas pipeline leakage emergency system is closed, the system can change gas pipeline in time when gas pipeline occurs to leak, from
And solve the problems, such as that prior art leads to not persistently provide a user with combustion gas because of fuel gas pipeline leakage.Additionally, the present invention is also
There is provided a kind of pipe gallery fuel gas pipeline leakage emergency method based on subsidiary conduit, the method can be in fuel gas pipeline leakage
When timely control gas pipeline and change its course.
In order to realize the purpose of the present invention, a kind of technical scheme for being adopted is：Pipe gallery based on subsidiary conduit fires
Feed channel leaks emergency system, including main gas pipeline, auxiliary gas pipeline and signal control process system, main gas pipeline and institute
State；Multiple main automatic valves are installed on the main gas pipeline, each
Auxiliary automatic valve is mounted on appendix；The signal control process system includes multiple gas concentration harvesters and data
Processing module, the gas concentration harvester signal output part are connected to the signal input part of the data processing module, institute
The signal output part for stating data processing module is respectively connecting to each main automatic valve and each auxiliary automatic valve.
Main gas pipeline and auxiliary gas pipeline of the above technical scheme by connection, and coordinate major-minor automatic valve,
During fuel gas pipeline leakage, system closes main automatic valve, and opens auxiliary automatic valve, so as to the combustion gas in main gas pipeline is cut
It is disconnected, and auxiliary gas pipeline is opened, combustion gas is conveyed from auxiliary gas pipeline, so as to solve in prior art because gas pipeline is let out
Leak and interrupt the problem to user's gas transmission.
In order to improve the intelligent of the application, in this improvements introduced it is：The signal control process system is also wrapped
Include the data transmission module with the data processing module two-way communication link.Can be by gas pipeline by data transmission module
In gas concentration value and leakage point position be sent to maintainer, be easy to maintainer to keep in repair.
In order to reach intuitively suggesting effect, the application in this improvements introduced is：The signal control process system
System also includes and the data transmission module alarm that signal output part is connected all the way.Gas concentration in gas pipeline reaches
To or more than threshold value when, alarm sounds, to maintainer send information while, by alarm song to relevant staff
Intuitively pointed out so that related personnel can know the disappointing situation of gas pipeline in gas pipeline in time.
Here, present invention also provides a kind of pipe gallery fuel gas pipeline leakage emergency method based on subsidiary conduit, is somebody's turn to do
Method is comprised the following steps：
S1：Setting gas concentration threshold, and each gas concentration harvester is numbered；
S2：Main automatic valve on main gas pipeline is all normally-open；
S3：Gas concentration in piping lane gas pipeline is acquired, gas concentration value is obtained；
S4：After gas concentration value is processed with setting gas concentration threshold carry out it is poor, if difference be equal to or
More than zero, then control main automatic valve and close, auxiliary automatic valve is opened；If difference is less than zero, execution step S3.
Above method controls the open and close of major-minor automatic valve according to the gas concentration in gas pipeline, in combustion gas
When pipeline has leakage, can timely change the conveyance conduit of combustion gas, realize uninterrupted supply.
In order to allow maintainer grasp gas concentration value exactly, it is easy to maintainer to formulate maintenance program, here
Improvements introduced is：If gas concentration value is equal to or more than zero with the difference of the gas concentration threshold of setting, will be the gas dense
Angle value short message sending is to maintainer.
In order to allow maintainer to be quickly found pipe leakage point, so as to shorten maintenance time, in changing that this is made
Entering is：If gas concentration value is equal to or more than zero with the difference of the gas concentration threshold of setting, corresponding gas concentration is adopted
The numbering short message sending of acquisition means is to maintainer.
Further, if gas concentration value is equal to or more than zero with the difference of the gas concentration threshold of setting, alarm
Report to the police.Relevant staff can intuitively be reminded by alarm sound, it is to avoid because do not check short message in time and not
The generation of the problem that gas pipeline can be keeped in repair in time.
The invention has the beneficial effects as follows：Solve in prior art because fuel gas pipeline leakage interrupts asking to user's gas transmission
Topic；Pipe leakage point position can be obtained exactly and avoid can not be to Gas Pipe because not checking short message in time
The generation of the problem keeped in repair in time by road.
