Description
Technical field
The utility model relates to a kind of gas detection alarm technique, particularly relates to a kind of gas pre-service monitor and alarm system.
Background technology
What present homemade main flow gas instrument adopted is gas chromatographic technique, need hydrogen, air, three kinds of gases of sample gas during the gas instrument operate as normal, we need carry out dry decontamination to above three kinds of gases for the operate as normal that guarantees gas instrument, when drying agent lost efficacy the back as untimely replacing, gently then influence the gas instrument job insecurity, heavy then influence chromatogram and go out the peak.And the sample gas pipeline in the mud exit might be flooded by mud, and mud will be pumped into instrument shelter by aspiration pump like this, will damage chromatographic apparatus as untimely discovery.Because having replacing in time or mud to be drawn into the sample device pipeline, drying agent do not cause the phenomenon of instrument cisco unity malfunction of common occurrence at the compound logging scene.
The utility model content
For overcoming the deficiency that prior art exists, the utility model provides a kind of gas pre-service monitor and alarm system.
Technical scheme: a kind of gas pre-service monitor and alarm system, be applied to gas instrument, in air, hydrogen, three kinds of gas pipings of sample gas, increase humidity sensor respectively, each humidity sensor is connected with the signal input part of single-chip microcomputer, and the signal output part of single-chip microcomputer drives corresponding hummer and/or light emitting diode respectively; Simultaneously negative pressure transducer is installed at the sample gas pipeline position, the signal output part of this negative pressure transducer is connected with signal processing module, filtering signal after treatment is delivered to the AD converting unit, this AD converting unit is connected with the single-chip data input end, and the signal output part of single-chip microcomputer drives corresponding hummer and/or light emitting diode respectively.
Described signal processing module for sampling, penetrate with, filtering circuit.
The beneficial effects of the utility model:
1, the utility model gas pre-service monitor and alarm system provides the monitoring, alarming function of air, hydrogen, sample gas three kinds of gas humidities, after drying agent lost efficacy, reminds the user in time to change drying agent with the form of sound and light alarm; This warning system is monitored the negative pressure of sample gas pipeline simultaneously, when suction mud or water, in time closes aspiration pump, avoids the gas instrument operation irregularity and the chromatogram components from being damaged that cause because of mud suction gas instrument.Whether the negative pressure part of reporting to the police can also leak gas to the aspiration pump diaphragm when cutting off front end sample gas pipeline and checks, avoids the chromatogram that causes because of diaphragm gas leakage unusual.This warning system provides communication interface with host computer with the form of serial ports, can check current gas humidity data by the host computer monitoring, and the negative pressure value of sample gas pipeline.
2, this Alarm System Design is used and has been filled up domestic gas instrument in the vacancy aspect this, can avoid the damage of suction mud to the chromatogram core devices, also can avoid drying agent to lose efficacy simultaneously and the chromatogram that causes is unusual.Can improve the work efficiency at compound logging scene, reduce the risk of chromatogram device failure.
