Rapid determination method for intelligent stink determinator and intelligent stink determinator

Abstract

The invention provides a rapid determination method for an intelligent stink determinator and the intelligent stink determinator, and the method comprises the following specific steps: carrying out a forward test, setting an initial dilution multiple, starting the test, independently judging whether a result of each sniffing identification person is correct or not, if an answer is correct, increasing the dilution multiple, continuing sniffing identification until an error occurs, and then calculating a personal threshold value of the sniffing identification person; carrying out negative testing, if the answer is wrong, progressively decreasing the dilution multiple until the sniffing identification person obtains the correct answer, and then calculating the personal threshold value of the sniffing identification person; and carrying out concentration calculation: calculating an average threshold value and the odor concentration after all the sniffing identification persons finish sniffing identification. According to the method disclosed by the invention, the initial concentration test results of the sniffing identification persons under the initial dilution multiple do not need to be all correct, and the positive and negative tests are respectively carried out according to different results, so that the olfactory threshold of each multiple is quickly found, the adjustment and test frequency of the initial dilution multiple are reduced, and the gas concentration determination efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of malodorous gas concentration measurement, in particular to a rapid measurement method for an intelligent odor measuring instrument and an intelligent odor measuring instrument. Background technique [0002] Odor measurement is an important basis for evaluating and controlling odor pollution and environmental law enforcement. In recent years, the emergence of intelligent odor detectors has effectively reduced the statistics and calculation of olfactory identification results, greatly improving the measurement efficiency. At present, my country generally adopts the three-point comparative smelly bag method introduced in the national standard method "Determination of Air Quality Odor by Three-point Comparative Smelly Bag Method GB / T14675-93". The more commonly used method in this method is the six-person test method. Similarly, the existing intelligent odor measuring instrument system generally only integrat...

At present, my country generally adopts the three-point comparative smelly bag method introduced in the national standard method "Determination of Air Quality Odor by Three-point Comparative Smelly Bag Method GB / T14675-93". The more commonly used method in this method is the six-person test method. Similarly, the existing intelligent odor measuring instrument system generally only integrates the method and calculation method. In this method, after selecting the initial dilution factor, the members of the sniffing team start to sniff. If all the identifications are correct, then continue to increase the dilution factor and proceed to the next round of olfactory identification; if the first olfactory identification is wrong, then go back two dilutions for olfactory identification until all members of the olfactory identification group can choose the correct answer. Then increase the dilution factor, the process of the determination method is relatively complicated, and it is necessary to repeatedly find the appropriate dilution factor before the formal measurement, and the determination efficiency of the intelligent odor tester is low

In addition, the structure of the airway in the prior art is more or less made of aluminum alloy, and the output malodorous gas tends to remain on its surface, reducing the accuracy of subsequent measurement results
