Description

Technical Field

[0001] The invention belongs to the technical field of sample detection, and in particular relates to a sample detection method for improving the safety level. Background Art

[0002] When purchasing bulk raw materials, manufacturers usually pre-select multiple suppliers, and choose suppliers and set prices based on the quality of the raw materials provided by the suppliers. However, when measuring the quality of materials, collusion and embezzlement between purchasing personnel and testing personnel often occur, and raw materials are passed off as high-quality ones, which seriously damages the interests of the company.

[0003] In order to avoid this kind of behavior, some manufacturers currently use multiple sets of sampling bottles to sample raw materials provided by different suppliers when purchasing and testing raw materials. Each set of sampling bottles matches the raw materials provided by one supplier, and different numbers AZ are marked on the sampling bottles for testing. However, this still cannot block the communication between purchasing personnel and testing personnel. Purchasing personnel can inform testing personnel of the supplier that matches the number, but it cannot block the communication between purchasing personnel and testing personnel, which makes it easy for testing data to be falsified. Summary of the invention

[0004] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a sample detection method with improved security level, which blocks the communication between the purchasing group and the detection group through the sampling box and the mixing group, thereby improving the security level of the detection result, preventing the interference of human factors on the detection result, and ensuring the objectivity and accuracy of the detection data.

[0005] The specific technical solution adopted by the present invention is:

[0006] A sample detection method for improving the safety level comprises the following steps:

[0007] S1. Prepare several groups of sampling bottles with numbers marked on the bottle caps;

[0008] S2. Place the sampling bottle in a sampling box, with the bottle cap of the sampling bottle exposed outside the sampling box, and the sampling box covering the body of the sampling bottle;

[0009] S3. The purchasing team uses different sampling bottles in the sampling box to sample raw materials from different suppliers;

[0010] S4. The purchasing team transfers the sampling box to the sample mixing team. The sample mixing team takes out the sampling bottles and shuffles their positions. Then, the bottle caps of the sampling bottles are randomly replaced. After the samples are mixed, the sampling bottles are put back into the sampling box and the bodies of the sampling bottles are covered.

[0011] S5. The sample mixing group transfers the mixed sampling box to the testing group. The testing group tests the raw materials in the sampling bottle and then inputs the test results into the system according to the label on the current bottle cap;

[0012] S6. The system restores the input test results based on the video and matches the test results with the supplier;

[0013] S3-S5 are monitored in real time by cameras throughout the whole process and the video is uploaded to the system, which includes a CPU and a storage unit.

[0014] The number of sampling bottles prepared in step S1 is greater than the number of suppliers, and the bottle caps of the sampling bottles are marked with numbers 1-N. In step S2, a corresponding number of sampling bottles are drawn from the sampling bottles 1-N according to the number of suppliers and placed in the sampling box.

[0015] The sampling box includes a groove-shaped box body and a cover plate located at the opening of the box body, one side of the cover plate is hinged to the sampling box, and the other side of the cover plate is locked with the sampling box by means of a lock, a plurality of groups of limit grooves are arranged in the chamber of the box body, and a through hole matching the position of the limit groove is arranged on the cover plate, the diameter of the through hole matches the diameter of the bottle cap, and the bottle cap of the sampling bottle passes through the cover plate along the through hole and is exposed to the outside of the sampling box.

[0016] The mixed sample group has a key that matches the lock.

[0017] The mixed sample group in step S4 includes mixed sample group one and mixed sample group two, and step S4 includes the following steps:

[0018] S411, the purchasing team transfers the sampling box to the mixing team, the mixing team takes out the sampling bottles and repositions them, then puts the sampling bottles into the sampling box and hides the bodies of the sampling bottles;

[0019] S412. Mixing group 1 will hand over the sampling box to mixing group 2. Sampling group 2 will randomly exchange the bottle caps of the sampling bottles and then hand over the sampling box to the testing group.

[0020] The beneficial effects of the present invention are:

[0021] The present invention provides a detection method, which first places the sampling bottle into a closed sampling box to avoid the purchasing group and the detection group from transmitting information with the help of the marks on the bottle body, and then the mixing group scrambles the position of the sampling bottle and the bottle cap number through disordered mixing, and then re-locks the sampling box and transfers it to the detection group for detection. At this time, the detection group cannot observe the bottle body, nor can it determine the supplier of raw materials in each sampling bottle according to the bottle cap number. Due to the existence of the sampling box and the mixing group, the communication between the purchasing group and the detection group is blocked, the safety level of the detection result is improved, the interference of human factors on the detection result is blocked, and the objectivity and accuracy of the detection data are guaranteed. DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. 1. Specific embodiments

[0024] S1. Prepare several groups of sampling bottles with numbers marked on the bottle caps;

[0025] S2. Place the sampling bottle in a sampling box, with the bottle cap of the sampling bottle exposed outside the sampling box, and the sampling box covering the body of the sampling bottle;

[0026] S3. The purchasing team uses different sampling bottles in the sampling box to sample raw materials from different suppliers;

[0027] S4. The purchasing team transfers the sampling box to the sample mixing team. The sample mixing team takes out the sampling bottles and shuffles their positions. Then, the bottle caps of the sampling bottles are randomly replaced. After the samples are mixed, the sampling bottles are put back into the sampling box and the bodies of the sampling bottles are covered.

[0028] S5. The sample mixing group transfers the mixed sampling box to the testing group. The testing group tests the raw materials in the sampling bottle and then inputs the test results into the system according to the label on the current bottle cap;

[0029] S6. The system restores the input test results based on the video and matches the test results with the supplier;

[0030] S3-S5 are monitored in real time by cameras throughout the whole process and the video is uploaded to the system, which includes a CPU and a storage unit.

[0031] At present, when some manufacturers purchase and test raw materials, since they are unable to block the communication between purchasing and testing personnel, it is inevitable that they will collude and embezzle, resulting in damage to the interests of the company.

[0032] Therefore, the present invention provides a detection method, which first places the sampling bottle into a closed sampling box to prevent the purchasing staff from marking special marks on the sampling bottle body, and then performs sampling. Each sampling bottle samples the raw materials of a supplier. After sampling, the purchasing group sends the sampling box to the mixing group. The mixing group opens the sampling box and scrambles the positions and bottle cap numbers of the sampling bottles through disordered mixing. The sampling box is then re-locked and transferred to the detection group for detection. Due to the existence of the mixing group, a blockage is formed between the purchasing group and the detection group. Even if the purchasing group informs the detection group of the position of the sampling bottle of supplier A in the sampling box and the bottle cap number, after the mixing by the mixing group, the bottle body position and bottle cap number of the sampling bottle of supplier A have been scrambled. Therefore, the detection group cannot determine which test result matches the raw materials of supplier A, thereby blocking the communication between the purchasing group and the detection group, preventing human factors from interfering with the test results, ensuring the objectivity and accuracy of the test data, improving the safety level of the test results, and avoiding the occurrence of falsification of test data.

[0033] In addition, because the sampling mixing group has repeatedly and disorderly shuffled the positions of the sampling bottles and the labels on the bottle caps, even the sampling mixing group finds it difficult to restore the original positions of each sampling bottle and cannot match the test results of the raw materials with their respective suppliers. Therefore, the entire sampling, mixing, and testing process is recorded. The system can restore the original positions of the sampling bottles based on the recordings to match the test results with the suppliers.

[0034] On the one hand, the camera is used to record the mixing process so that the system can restore the test results after mixing and match them with the real supplier. On the other hand, the entire work of the staff is monitored in real time under the camera, which can also prevent the staff from stealing and improve the security level of the test results.

[0035] The system includes a CPU and a storage unit. The detection group uses a computer, a mobile phone and other data input devices to match and input the detection results with the current bottle cap label. The detection results are entered into the storage unit, and the camera video is transmitted to the storage unit. Then the CPU reads the video and the detection results in the storage unit respectively, and matches the detection results with the actual supplier according to the mixing process of the video. Finally, the matching table of the detection results and the actual supplier is wirelessly transmitted to the administrator's computer or mobile phone via WiFi.

[0036] The number of sampling bottles prepared in step S1 is greater than the number of suppliers. The bottle caps of the sampling bottles are marked with numbers 1-N. In step S2, the corresponding number of sampling bottles are drawn from the sampling bottles 1-N according to the number of suppliers and placed in the sampling box. The sampling bottles are also randomly drawn to prevent the purchasing team from making marks somewhere on the sampling bottles in advance and colluding with the testing team. When the sampling bottles and sampling boxes are handed over to the purchasing team, the entire process is recorded by cameras to prevent the purchasing team from marking on the sampling bottles.

[0037] The sampling box includes a groove-shaped box body and a cover plate located at the opening of the box body, one side of the cover plate is hinged to the sampling box, and the other side of the cover plate is locked with the sampling box by means of a lock, a plurality of groups of limit grooves are arranged in the chamber of the box body, and a through hole matching the position of the limit groove is arranged in the cover plate, and the diameter of the through hole matches the diameter of the bottle cap, and the bottle cap of the sampling bottle passes through the cover plate along the through hole and is exposed to the outside of the sampling box. The sampling bottle in this specific embodiment has a bottle structure that is narrow at the top and wide at the bottom. When the cover plate is locked with the sampling box, the sampling bottle cannot be drawn out from the through hole of the cover plate. After the mixing is completed, only the bottle body of the sampling bottle is necessarily matched with the raw material. Therefore, the bottle body of the sampling bottle is hidden in the sampling box to prevent the purchasing group from contacting and observing the bottle body with the testing group, thereby preventing the purchasing group and the testing group from communicating and colluding with the bottle body of the receiving group.

[0038] The sampling mixing group has a key that matches the lock. During the entire testing process, only the sampling mixing group can open the sampling box. The purchasing group cannot open the sampling box to mark the sampling bottles. Even if the sampling bottles are marked in advance, the testing team cannot open the sampling box to observe whether there are marks on the bottle bodies of the sampling bottles.

[0039] The mixed sample group in step S4 includes mixed sample group one and mixed sample group two, and step S4 includes the following steps:

[0040] S411, the purchasing team transfers the sampling box to the mixing team, the mixing team takes out the sampling bottles and repositions them, then puts the sampling bottles into the sampling box and hides the bodies of the sampling bottles;

[0041] S412. Mixing group 1 will hand over the sampling box to mixing group 2. Sampling group 2 will randomly exchange the bottle caps of the sampling bottles and then hand over the sampling box to the testing group.

[0042] By having two groups of sample mixers shuffle the bottle bodies and bottle cap labels of the sampling bottles respectively, the disorder of the mixed samples can be further improved to increase the safety level of the test results.
