Abstract

The invention belongs to the technical field of a communication technology and a detection technology, and discloses a combustible gas leakage detection device, which comprises an electromagnetic valve (1), a gas sensitive element (2), a GPRS (General Packet Radio Service) transmitting module (3), a control module (4), an alarm module (5) and a switch (6), wherein the control module (4) is connected with the GPRS transmitting module (3); the electromagnetic valve (1) is connected with the control module (4); the alarm module (5) is connected with the control module (4); the gas sensitive element (2) is connected with the control module (4); and the electromagnetic valve (1) is arranged on gas pipeline. The GPRS transmitting module is controlled by the control module to transmit gas leakage information; the control module is timely communicated with a supervision department; a countermeasure is timely taken; and the electromagnetic valve is arranged, so that leakage gas can be automatically plugged to prevent danger from being further expanded.

Description

The inflammable gas leak detection apparatus
Technical field
The invention belongs to the communication technology and field of gas detection, be specifically related to a kind of inflammable gas leak detection apparatus.
Background technology,
In the last few years, rock gas, coal gas utilization rate in every household was very high, for city dweller's daily life provides guarantee; But people bring people simultaneously easily at enjoyment rock gas, coal gas, also have the accident of rock gas, gas leak to take place frequently, and the resident in this house suffers a loss or threat to life; When running into burning things which may cause a fire disaster; Also might set off an explosion, bring disaster to other neighbours, loss is very heavy; So do not eliminate when the potential safety hazard of some coal gas, natural gas leaking, all maybe people's life and property be threatened at any time.
The inspection of existing coal gas, natural gas leaking mainly is through manual mode or uses instrument to detect; There are many shortcomings: coal gas, rock gas user are needed examination one by one; The user stays out and also can't detect; The promptness of finding gas leak simultaneously is also very poor, can't reach timely detection and find dangerous; When detecting, need directly to contact with the inflammable gas of pipeline, during measurement there is crushing in air feed.
In some family the gas leak sensor has been installed at present, after indoor coal gas reached finite concentration, sensor moved; Warning tells the user that coal gas leaks, and this method can improve the level of safe usefulness gas, but still is the prevention method of passive type after all; In case find that warning needs the manual work intervention; If no one in the room can't be sent to air feed department with dangerous information, can't in time carry out shutoff.
As disclosing a kind of gas leak warning horn among the patent CN 101958037A, by the alarm that gas sensor, relay are formed, when gas leak surpassed required standard, the working power of not having the radiating circuit of rationing the power supply was connected in the relay adhesive; Gas sensor can be formed gas leak wireless remote control warning horn, when gas leak surpasses the safety standard concentration that sets is, the gas sensor output detection signal sends alerting signal after amplifying, handling.This mode must be that shutoff is carried out in artificial operation, if family nobody cause leak time long, also can cause major safety risks or accident to take place.
This shows; Major part all can only make warning function in the existing technology; Information is not delivered to special department through means of communication, the very first time that can not when leakage accident takes place, report to the police prevents a large amount of hazardous gas leakages with regard to the means of taking automatic shutoff.
Summary of the invention
1, the object of the invention.
In order to strengthen the promptness that supervision department obtains information, can in time grasp the situation of every family gas leakage, and can in the gas leakage alarm, carry out shutoff automatically, prevent dangerous further expansion, the present invention has been proposed.
2, the technical scheme that the present invention adopted.
The inflammable gas leak detection apparatus; Comprise gas sensor 2, alarm module 5, switch 6, GPRS transmitter module 3, solenoid valve 1, control module 4; Described control module 4 links to each other with GPRS transmitter module 3, said solenoid valve 1 links to each other with control module 4; Described alarm module 5 links to each other with control module 4, and described gas sensor 2 links to each other with control module, and said solenoid valve 1 is installed on the gas pipeline.
In a specific embodiment of the present invention, described alarm module 5 adopts acoustic-optic alarm.
Described alarm module 5 transmits signal to control module 4 when working, by control module 4 control GPRS transmitter modules 3 transmission information.Described gas sensor 2 its sensitive body are with the very little SnO of particle diameter 2Powder is a stock.Described alarm module 5 quits work when receiving after control module sent signal to the GPRS module automatically.After gas sensor 2 detects inflammable gas, this information is sent to control module 4, closes solenoid valve 1 by control module 4 controls, solenoid valve 1 cuts out gas pipeline.
When gas sensor is checked through gas leakage, transmit signal to control circuit, warning is sent in the work of control circuit control warning module, controls the GPRS transmitter module simultaneously, the gas leakage information is passed, and control electromagnetic valve in time closes, and blocks gas pipeline.
3, beneficial effect of the present invention.
Send gas leakage information through control module control GPRS transmitter module; Can realize in time communicating by letter, supervision department is in time taken action, simultaneously the setting through solenoid valve with supervision department; Can in time leak and carry out shutoff automatically, prevent dangerous further expansion gas.

Embodiment
Embodiment
In order clearly to introduce practical implementation process of the present invention, the present invention is made the following specifically describes.
Solenoid valve in the inflammable gas leak detection apparatus is installed on the gas pipeline, and elements such as gas sensor 2, alarm module 5, switch 6, GPRS transmitter module 3, control module 4 are installed in adjacent gas channel through integrated.
Described control module 4 links to each other with GPRS transmitter module 3, said solenoid valve 1 links to each other with control module 4, and described alarm module 5 links to each other with control module 4, and described gas sensor 2 links to each other with control module, and said solenoid valve 1 is installed on the gas pipeline.
Alarm module 5 adopts acoustic-optic alarm.Described alarm module 5 transmits signal to control module 4 when working, by control module 4 control GPRS transmitter modules 3 transmission information.Described gas sensor 2 its sensitive body use the very little SnO2 powder of particle diameter to be stock.Described alarm module 5 quits work when receiving after control module sent signal to the GPRS module automatically.After gas sensor 2 detects inflammable gas, this information is sent to control module 4, closes solenoid valve 1 by control module 4 controls, solenoid valve 1 cuts out gas pipeline.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
