Abstract
The invention discloses an electronic nose system used for measuring and discriminating gas, which belongs to the field of electronic noses. To facilitate digitlization of measured signals of an electronic nose, the electronic nose system provided by the invention comprises a solenoid valve, a sensor array, a pressure buffer, a sucking pump, a flowmeter, a connection bayonet and a computer, wherein gas enters the pressure buffer through the solenoid valve, the pressure buffer is connected with the sucking pump, the sucking pump is connected with the flowmeter through a sampling tube, and the solenoid valve, the sensor array and the sucking pump are connected with the computer through the connection bayonet. The electronic nose system employs a combination of the sensor array, the sucking pump and the connection bayonet, so the digitlization degree of the measured signals of the electronic nose is higher.
Description
Technical field
The present invention relates to Electronic Nose field, particularly relate to a kind of electric nasus system measuring and distinguish gas.
Background technology
Electronic Nose is that simulated animal olfactory organ develops a kind of high-tech product, and current scientist does not also all make the sense of smell principle of animal clear.But along with the development of science and technology, comparatively some universities of authority have developed the Electronic Nose with widespread use in the world at present, the foremost Universitaet Hamburg that will count Germany has absolute authority in the sensor field of the world today.Wherein the design of sensor and Electronic Nose hardware and Electronic Nose are the focuses in Electronic Nose research in the application of food and agriculture field.
Summary of the invention
The present invention will solve above technical matters, provides a kind of electric nasus system measuring and distinguish gas, and it is convenient by the measuring-signal digitizing of Electronic Nose to come.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of electric nasus system measuring and distinguish gas, comprise solenoid valve, sensor array, pulsation dampener, aspiration pump, flowmeter, connect bayonet socket, computing machine, gas enters pulsation dampener by solenoid valve, pulsation dampener is connected with aspiration pump, aspiration pump is connected by sampling pipe with flowmeter, and solenoid valve, sensor array, aspiration pump are connected with computing machine by connecing bayonet socket.
Wherein, sensor array is arranged in measuring chamber, and solenoid valve switches gas to be measured and dry air.
Compared with prior art, the invention has the beneficial effects as follows: present invention employs sensor array, aspiration pump and connect the combination of bayonet socket, make the measuring-signal digitized degree of gas higher.
Accompanying drawing explanation
Fig. 1 is theory structure schematic diagram of the present invention.
