Control cabinet starting moves back and forth electromagnet 19 and rotating electric machine respectively promotes sample pedestal rotating driver 20, and sample
The rotation of this pedestal rotating driver 20 drives sample pedestal 2 to rotate, and after rotation is turned around, bar code scanning module 18 detects that sample tries
Bar code on agent bottle 1, and DFB semiconductor laser to detection pattern detection microorganism situation, while visual sensor acquire
1 lower part liquid of video situation and sample reagent bottle on 1 top nutrient agar of sample reagent bottle or identification chromogenic culture medium
Body culture medium situation of change, visual sensor acquire realtime video transmission to monitoring client, and staff directly observes video, bar code
Scan module 18 and the information of DFB semiconductor laser detection are transmitted to controller, and controller will test result and be connect by network
Mouth 7 is transmitted to monitoring client.The sample reagent bottle 1 that detection is completed is gone out by 15 band of chain to inlet and outlet 10, by manually by the part sample
One-time detection process is completed in this taking-up.
Embodiment 2: the automatic rapid detection system of food microorganisms, the setting quantity of the detecting box are at least one set, inspection
It surveys cabinet to be connected with monitoring client by network interface 7, is applied in combination by multiple groups detecting box, greatly improves detection sample size
And detection efficiency, user can substantially increase the scope of application of integral device according to self-demand.
Remaining structure and the course of work are same as Example 1.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
