Description
Technical field
The present invention relates to a kind of combustion gas leakage monitoring warning device, be specifically related to a kind of centralized domestic gas leakage monitoring warning device.
Background technology
Along with expanding economy, use the domestic consumer of pipe gas more and more, also more and more because of the security incident that gas leakage causes, in case revealing, combustion gas handled timely and effectively again, can cause extremely serious consequence.It is less that the domestic consumer purchases installation fuel gas alarm ratio at present, mainly contains following three reasons: the one, and higher because of the fuel gas alarm price, be difficult to popularize; The 2nd, what many domestic gas alarms adopted is some gas securities, poor-performing, and sensitivity and selectivity are not high, and the situation of failing to report or reporting by mistake in actual the use is very many; The 3rd, fuel gas alarm needs regular detection sensitivity after installing, overwhelming majority product requirement serviceable life is in two years, expiredly need purchase new alarm again, increase customer using cost, and require in the operating period, also to require once examine and determine in every month, guarantee operate as normal, general domestic consumer is difficult to examine and determine on request.Above effects limit the universal use of gas safe monitoring alarm at civilian family.
The user who at present domestic gas detection alarm device has been installed; usually adopt the one or more gas securities in a family; fuel gas shutoff valve or vent fan are reported to the police and are handled interlock in the connection; fuel gas alarm is because of power problems; much all need external power supply to use; for long-term unmanned user; the total lock of home circuit cuts out the back just can't carry out detection alarm; even adopt battery powered; also there is same problem in battery after having consumed electricity; so even now a lot of domestic consumer has installed fuel gas alarm; also can't accomplish daily instant; monitoring and protecting effectively; uninhabited for a long time again after particularly opening for some combustion gas, lack normal safety inspection, the probability that goes wrong is bigger.
What also have at present that a kind of centralized warning device adopts is that alarm signal with each family in the building is transferred to concentrated place by bus mode, carry out interlink warning, this mode still can't solve single household cost height, the defective that breaks down and in time to safeguard, simultaneously the reliability of concentrated alarm still depends on the quality of the alarm that this family resident is selected, and because the cost ability to accept at civilian family has determined the reliability of alarm and accuracy not high.
Summary of the invention
The present invention is directed to above-mentioned weak point, designed a kind of centralized domestic gas leakage monitoring warning device, purpose is: propose reliability and sensitivity greatly when reducing installation of combustion gas leakage monitoring warning device and use cost.
Technical solution of the present invention:
A kind of centralized domestic gas leakage monitoring warning device, comprise and detect pipeline, pipeline extractor fan, home terminal user and always monitor device, it is characterized in that: each home terminal user is connected with total monitoring device by detecting pipeline, by pipeline the gas delivery to be measured of terminal user family is detected processing to total check point, determine to reveal the position by the control and the logic determines of combustion gas detected value concentration change and main control chip; Each home terminal user installation has overhead control signal receiving processing module, detected gas to carry control module, alarm module, always monitors device and comprises extractor fan, combustion gas detecting sensor and the centralized control module that is installed in the monitoring pipe end.
The overhead control signal receiving processing module of described home terminal user installation is connected with master controller by wired mode, receives its instruction;
It is electric machine valve and extractor fan that the detected gas of described home terminal user installation is carried control module;
The alarm module of described home terminal user installation is an audible-visual annunciator;
Described home terminal links to each other with master controller along detecting pipeline by multiple core cord, and the required electric energy of each terminal can be concentrated by total check point by electric wire and provide;
Described pipeline extractor fan can be taked at the monitoring pipe end air extractor to be installed, and perhaps in the position that the terminal user of family is connected with the detection pipeline the common mode that extracts gas to be detected of small-sized air exhauster is installed simultaneously;
The centralized control module of described total monitoring device comprises main control chip and the wireless alarm signal sending module, control module, the display device that are attached thereto.
Beneficial effect of the present invention:
1, reduces single household early investment and the maintenance cost of domestic consumer greatly for combustion gas detection alarm system;
2, effectively promote the reliability and the accuracy of gas leakage monitoring;
3, be beneficial to the specialized maintenance management that realizes monitor and alarm system, can in time pinpoint the problems and effectively processing.
Description of drawings

Embodiment
Specify invention below in conjunction with embodiment.
As shown in Figure 1, by detecting pipeline 3 each home terminal user 2 is connected with total monitoring device 1, each home terminal user 2 is equipped with audible-visual annunciator 2-2, master control signal receiving processing module 2-1 and electric machine valve 2-3, always monitors device 1 and comprises extractor fan 1-1, combustion gas detecting sensor 1-2, main control chip 1-3, wireless alarm signal sending module 1-4 and control and the display 1-5 that is installed in monitoring pipeline 3 ends.Home terminal user 2 also can install small-sized air exhauster (diagram is not provided) with the position that detection pipeline 3 is connected.
As shown in Figures 1 and 2, system is under normal operation, each home terminal user 2 is by going into to be installed in and detect the small-sized air exhauster of pipeline 3 link positions, indoor gas is drawn in the detection pipeline 3, the end of monitoring pipeline 3 is equipped with extractor fan 1-1, keeps detecting the negative pressure in the pipeline 3, and gas to be detected is flowed to detecting pipeline 3 outlets by indoor, highly sensitive combustion gas detecting sensor 1-2 places and detects pipeline 3 outlet air chamber, detected gas in real time.
The pipeline front end of registering one's residence has a gas electric machine valve 2-3, under the normal condition, evacuating valve is all opened, by small-sized air exhauster detected gas is delivered to total monitoring device 1, in having found sampling observation gas, there is combustion gas, then main control chip 1-3 sends instruction by signal wire alerting signal sending module 1-4, moment is closed the evacuating valve of setting amount, if no longer detect combustion gas behind the setting-up time, then judge the leak point in closing the family, as still have combustion gas in taking a sample test air, then judge in the user of valve opening, to exist and reveal, program opens and closes according to this again, reveals the user up to orienting.Send control signals to this family simultaneously, user's master control signal receiving processing module 2-1 guide sound light crossing-signal 2-2 reports to the police.
In addition, native system can also be revealed concentration according to detected single household combustion gas, such as reaching the setting alarm threshold value, and other treatment facility that links, as close burnt gas valve, open vent fan, send alarming short message to user mobile phone and gas company.
