Description
Technical field
The utility model relates to a kind of mining gas detecting instrument, particularly relates to a kind of methane transducer automatic zero set (AZS) system.
Background technology
In coal mine, methane reaches certain concentration, easily set off an explosion, cause security incident, so will often detect the content of methane in coal mine, the existing content that detects methane in mine mainly adopts methane transducer, the principle of work of sensor itself is when having gas to exist, and in sensor, sensing element is followed the proportional electric current of gas concentration to one of γ-ray emission chemical reaction output, determines the concentration of current carbon monoxide by the magnitude of voltage that detects electric current.But due to the impact of external environment condition, after sensor works long hours, can cause sensor there is no also to produce a small electric current under the environment of gas, drifted about the zero point of sensor, make detection inaccurate.At present, the zeroing of sensor is all the manual adjustment of regularly carrying out by telepilot, and so not only waste of manpower has brought a lot of inconvenience for the safety management of mine and the maintenance of mining product.
Because the defective that above-mentioned existing methane transducer exists, the design people, actively research and innovation in addition, to founding a kind of portable methane detector of new structure, make it have more practicality.
The utility model content
Fundamental purpose of the present utility model is, overcome the defective that existing methane detector exists, and provide a kind of methane transducer automatic zero set (AZS) system of new structure, technical matters to be solved be can have or without the environment of methane in automatic zeroising, thereby more be suitable for practicality, and have the value on industry.
The purpose of this utility model and solve its technical matters and realize by the following technical solutions.Methane transducer automatic zero set (AZS) system according to the utility model proposes comprises methane transducer, single-chip microcomputer, detection output circuit and electronic switch, and described electronic switch is used for controlling the switching of this system;
Described methane transducer is used for gathering the concentration signal of methane in environment and converting current signal to;
Described detection output circuit, the current signal that gathers that is used for receiving and transmit methane transducer is to single-chip microcomputer, and described single-chip microcomputer analysis sends a signal to methane transducer.
Aforesaid methane transducer automatic zero set (AZS) system, wherein, described single-chip microcomputer is connected with alarm.
By technique scheme, the utility model methane transducer automatic zero set (AZS) system can carry out automatic zero set (AZS) to methane transducer, saves time, and saves manpower, has reduced worker's burden.
In sum, the methane transducer automatic zero set (AZS) system of the utility model special construction, it has above-mentioned many advantages and practical value, thereby more is suitable for practicality.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
