Brief description of the drawings
Fig. 1 is the structure diagram of the utility model Portable detection instrument for multiple gases.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1, a kind of Portable detection instrument for multiple gases of the utility model, including gas sensor, warning device,
Display device, memory, singlechip controller, micro air pump and detection gas chamber, the gas sensor are installed on detection gas chamber
It is interior；The singlechip controller connects gas sensor, warning device, display device, memory respectively；The gas sensor
For the gas concentration signal of collection to be switched to voltage signal and enhanced processing；The singlechip controller receives enlarged electricity
Analysis meter calculation is carried out after pressing signal；The display device is used to show the concentration value after singlechip controller computing；It is described to deposit
Reservoir is used to store the exceeded event of concentration of toxic gases and last time detector prover time detected every time.The gas
Sensor is oxygen sensor or flammable gas sensor or optional two kinds of toxic gas sensors or PID sensor.The alarm
Device is two or more in sound, light or vibrations warning device, is two kinds or more of buzzer, LED light or vibrator respectively
Kind.Warning device sets two grades, low value alarm and high level alarm.The display device is liquid crystal display, for showing
The real time monitoring concentration value of five kinds of gases CO, O2, CH4, H2S, VOC.The micro air pump includes standard gas hole, venthole and pipeline
Filter.
By taking carbon monoxide (CO) as an example, the range of gas detecting instrument is 0-1999ppm, and least count is 1ppm, low report value
It is 50ppm, high report value is 100ppm.When the concentration of CO in air reaches 50ppm, alarm activation, at this moment buzzer,
Two or more of LED light or vibrator are started to work, and the corresponding time is 15 seconds.When the concentration of CO in air reaches 100ppm
When, one or more start-up operations of alarm activation, at this moment buzzer, LED light or vibrator, the corresponding time is 30 seconds.
By taking hydrogen sulfide (H2S) as an example, the range of gas detecting instrument is 0-100.0ppm, and least count is 0.1ppm, low report
Value is 10ppm, and high report value is 20ppm.When the concentration of H2S in air reaches 10ppm, alarm activation, at this moment buzzer,
One or more start-up operations of LED light or vibrator, corresponding time are 30 seconds.When the concentration of H2S in air reaches 20ppm
When, one or more start-up operations of alarm activation, at this moment buzzer, LED light or vibrator, the corresponding time is 60 seconds.
Detector after a period of time using needing to be calibrated to ensure the precision of detector measurement result, memory recording
The time of record last time calibration, when each detector is opened, the date of last time calibration all shows in liquid crystal display, work
