Abstract
The invention discloses a sampling process monitoring method and a detection system. The sampling process monitoring method sequentially comprises the following steps of: moving a sampling gun to a suction nozzle area, wherein blank suction nozzles are arrayed in the suction nozzle area, and downwards moving the sampling gun to absorb one suction nozzle; moving the sampling gun to a monitoring area, and detecting whether the head of the sampling gun absorbs the suction nozzle or not in the monitoring area; if the suction nozzle is monitored to be absorbed by the head of the sampling gun, moving the sampling gun to a sample area to absorb a sample, and moving to a detection area to release the sample for detection; if the suction nozzle is monitored to be not absorbed by the head of the sampling gun, reassembling the suction nozzle; and after the sample is released, discarding the used suction nozzle, and returning the sampling gun to an initial position. In the invention, whether the sampling gun absorbs the suction nozzle or not is detected before the sampling gun absorbs the sample, the sampling gun automatically returns for reassembly of the suction nozzle if the sampling gun does not absorb the suction nozzle, and the advantages of no manual intervention, no sample omission during detection and convenience for operation are achieved.
Description
Technical field
The present invention relates to a kind of sampling process monitoring method and detection system, relate in particular to a kind of sampling process monitoring method and detection system that is applied to chemistry or biological aspect.
Background technology
Along with the development of chemistry or biological field detection means, and produce, increase that experiment needs test sample, the apparatus and method for of automatic monitoring also arises at the historic moment thereupon.
For instance, usually need in the biochemistry detection sample is carried out film-making dyeing, present automatic staining method and automatic staining machine adopt following steps usually:
Sampling gun is moved to the suction nozzle district, and the suction nozzle district is arranged with blank suction nozzle, and sampling gun moves downwards, picks up suction nozzle;
Sampling gun is moved to sample area, draw sample, move to detection zone release sample and detect;
Abandon used suction nozzle, sampling gun returns initial position, waits for new sampling instruction.
When but sometimes sampling gun picks up suction nozzle, suction nozzle is not picked up, or pick up the back in conjunction with not firm, suction nozzle comes off immediately, and the operation as usual of system's this moment, carry out successively and draw sample, discharge operations such as sample, when losing time, also incur loss through delay the comprehensive of testing result, often after a collection of dozens of and even up to a hundred sample detection are intact, which sample operating personnel need manually search does not have sampled rifle to draw and the release detection, arrange then to detect again, both wasted time and energy, but also easy omission sample.
At the problems referred to above, the someone proposes suction nozzle is detected in the industry, does not inhale when suction nozzle is arranged when detecting sampling gun, sends promptings such as acousto-optic, suspends simultaneously and detects, and reminds operating personnel to operate again.But this method needs the real-time execute-in-place of people, and suspends repeatedly and detect, and resets operation and loaded down with trivial details, inefficiency again.
Summary of the invention
The object of the present invention is to provide a kind of exhaustively automatic sampling process detection method that a kind of detection system of using said method is provided simultaneously.
For solving above-mentioned first technical matters, the invention provides a kind of sampling process monitoring method, may further comprise the steps successively:
Step 1: sampling gun is moved to the suction nozzle district, and the suction nozzle district is arranged with blank suction nozzle, and sampling gun moves downwards, picks up suction nozzle;
Step 2: sampling gun moves to monitoring section, and whether detection sampling gun rifle head is inhaled suction nozzle is arranged in monitoring section,
If monitor the suction of sampling gun rifle head suction nozzle is arranged, carry out step 3,
Do not have suction nozzle if monitor sampling gun rifle head, then execution in step 1;
Step 3: sampling gun is moved to sample area, draw sample, move to detection zone release sample and detect;
Step 4: abandon used suction nozzle, sampling gun returns initial position, waits to receive that new sampling detects instruction, execution in step 1.
Be different from nothing monitoring sampling or the simple warning and the time-out detection of prior art to no suction nozzle sampling gun, whether the present invention's detection sampling gun before drawing sample is inhaled suction nozzle is arranged, if do not inhale suction nozzle arranged, then return automatically and reinstall suction nozzle, need not artificial interference, detect and do not leak sample, easy to operate.
Wherein, whether detect sampling gun rifle head described in the step 2 in monitoring section inhales suction nozzle is arranged, the method that adopts is at monitoring section infrared detector to be set, whether infrared detector monitoring sampling gun lower end is present in the height below of setting, if the sampling gun lower end is present in the height below of setting, being judged as the suction of sampling gun rifle head has suction nozzle, if the sampling gun lower end is not present in the height below of setting, being judged as sampling gun rifle head does not have suction that suction nozzle is arranged.
