Description
Technical field
The utility model relates to a kind of toxic gas detection device of chemical laboratory.
Background technology
Often contain the harmful gases such as CO, NH3, NO, NO2 in the chemical laboratory, can produce harm to respiratory system during low concentration, can cause people's stupor during high concentration until dead, it is very necessary therefore chemical laboratory being carried out toxic gas detection.The device that some integrated multiple gases sensors are arranged is in the market realized detecting multiple gases by changing the sensitive gas detection probe, also is only limited to the switching of gas circuit on its function, and is confined to manually-operated.These gas detector integrated equipments are more, and detection speed is slower, and volume is relatively large, complicated operation, and detection is wasted time and energy, and the gas that is not suitable in the laboratory detects.
The utility model content
For the problems referred to above, it is a kind of compact to design that the utility model provides, and the detection reaction time is fast, can detect multiple toxic gas, detecting the toxic gas detection device that the chemical laboratory of prompt functions is arranged when toxic gas acquires a certain degree simultaneously.
For achieving the above object, the toxic gas detection device of the utility model chemical laboratory, comprise housing, be arranged on the microprocessor of the gas sensor in the described housing, the analog to digital converter of described gas sensor connection, the connection of described analog to digital converter, key panel and warning output device that described microprocessor connects, wherein also comprise being arranged on the power supply changeover device that described housing is powered for the each several part of described toxic gas detection device outward, described microprocessor also connects printer.
Further, described warning output device comprises LCDs, light crossing-signal and voice guard, described LCDs, light crossing-signal and voice guard are connected with described microprocessor and are connected, and wherein said light crossing-signal comprises the LED lamp of at least two group different colours.
Further, described gas sensor is one or more the combination in CO gas sensor, NH3 gas sensor, NO gas sensor, the NO2 gas sensor.
Especially, also comprise the wireless telecommunication system that is connected with described microprocessor.
The toxic gas detection device of the utility model chemical laboratory, safe and reliable, accuracy of detection is high, and is simple in structure, detects the save trouble and labor.
Description of drawings
Fig. 1 is the theory structure synoptic diagram of the toxic gas detection device of the utility model chemical laboratory.
Embodiment
Below in conjunction with Figure of description the utility model is further described.
As shown in Figure 1, the toxic gas detection device of the utility model chemical laboratory, comprise housing, be arranged on the microprocessor of the gas sensor in the described housing, the analog to digital converter of described gas sensor connection, the connection of described analog to digital converter, key panel and warning output device that described microprocessor connects, wherein also comprise being arranged on the power supply changeover device that described housing is powered for the each several part of described toxic gas detection device outward, described microprocessor also connects printer.
Further, described warning output device comprises LCDs, light crossing-signal and voice guard, described LCDs, light crossing-signal and voice guard are connected with described microprocessor and are connected, and wherein said light crossing-signal comprises the LED lamp of at least two group different colours.
Further, described gas sensor is one or more the combination in CO gas sensor, NH3 gas sensor, NO gas sensor, the NO2 gas sensor.
Especially, also comprise the wireless telecommunication system that is connected with described microprocessor.
After detection gas enters the detector device, gas sensor produces corresponding simulating signal, signal enters little processing processor through the magic converter, this signal of device that is untreated calculates testing result and outputs to the warning output device, and the in real time concentration work of gas shows on the display screen of output alarm equipment in real time in the laboratory.When the harmful gas in the laboratory exceeds standard, described voice guard controlled by described microprocessor and described light crossing-signal is reported to the police respectively simultaneously, the quantity of the LED lamp color of described light crossing-signal and the kind of described gas sensor are corresponding, the LED lamp of respective color is lighted when the harmful gas of the type of correspondence exceeds standard, the convenient type of in time finding out the harmful gas that exceeds standard.The wireless telecommunication system that microprocessor connects has been realized the remote monitoring in laboratory and the long-range output of laboratory toxic gas, in case of emergency makes things convenient in the laboratory in addition and outwards seeks help.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
