Abstract
The invention discloses a novel positioning device for fuel gas leakage in the field of security detection devices. The novel positioning device comprises a fuel gas concentration detection unit, wherein the fuel gas concentration detection unit comprises a plurality of methane sensors; a signal output end of the fuel gas concentration detection unit is connected with a signal input end of a microprocessor; and a signal output end of the microprocessor is connected with a sound-light alarm circuit and a data display unit respectively. According to the novel positioning device for the fuel gas leakage, concentration of methane in the position of each sensor is measured, so that a fuel gas leakage position can be positioned accurately, a leakage point can be found in time, a fault can be eliminated, the safety performance is improved, and the device is applicable to detection of fuel gas leakage.
Description
Technical field
The present invention relates to a kind of safety detection device, particularly a kind of gas leakage positioning device.
Background technique
Along with the adjustment of national energy structure and the raising of living standards of the people, combustion gas has become the important energy source of national product and life, the main consumption terminal of combustion gas is many in the city, gas transmission pipeline net work mainly concentrates on the population yarding district, it is underground that main mainly is laid on highway, prop up net and be distributed in housing-group and indoor, the incident of leakage that causes owing to reasons such as burn into crackles has generation frequently.Gently then cause the wasting of resources, environmental pollution; Heavy then set off an explosion, catch fire, poison, jeopardize the safety of life and property of user and peripheral population, bring immeasurable loss to society.
The great attention that has obtained people with regularly safety check is rushed to repair in leakage to gas ductwork, leaks the detection and localization instrument and bringing into play irreplaceable effect in repairing, safety check and accident treatment.Yet aspect leak point positioning, the many concentrations according to gas leakage of conventional art are judged the leakage point position, think that the concentration biggest place is leakage point.Yet engineering practice finds, because of the impact of the factors such as landform and environment, the distribution of gas concentration often is not that under the perfect condition certain is a bit the highest, distribute but become regional, thereby general technology can't realize that the leakage point highi degree of accuracy locates fast.
Summary of the invention
The purpose of this invention is to provide a kind of novel gas and reveal positioning device, can realize the accurate location to the gas leakage position, can in time find the leak point, thereby fix a breakdown, improved Safety performance.
The object of the present invention is achieved like this: a kind of novel gas is revealed positioning device, comprise the gas concentration detection unit that is formed by a plurality of methane transducers, the signal output part of described gas concentration detection unit links to each other with the signal input part of microprocessor, and the signal output part of described microprocessor is connected with respectively sound light alarming circuit and data display unit.
When the present invention works, methane transducer detects tested point gas concentration data by the gas concentration detection unit with sensor and sends microprocessor to, microprocessor calculating concentration variance ratio and according to concentration and the variance ratio possibility that to calculate current point be leakage point is shown to the user by acousto-optic hint circuit and LCD display circuit with the result at last.Compared with prior art, beneficial effect of the present invention is, this device can be realized the accurate location to the gas leakage position by measuring the methane concentration of each sensing station, can in time find the leak point, thereby fix a breakdown, and has improved Safety performance.This device can be used in the detection to gas leakage.
As a further improvement on the present invention, be provided with USB on the described microprocessor and outreach expanding element.Can be in time with data upload to PC.
