Abstract
The invention discloses a misinformation-free detection method of a liquid detector and relates to the field of liquid detection. According to the method, the two poles of a detection antenna in the detector are interchanged, and detection is conducted with electrodes at the two ends of the detection antenna serving as emission electrodes; at the moment, other electrodes on the detection antenna all serve as receiving electrodes and receive signals fed back to the corresponding positions, and then the signals are input into a processor through signal input points respectively; comparative analysis is conducted on the two groups of received signal data by the processor, the component information of detected liquid is displayed through a display screen if the two groups of signal data are consistent, and information showing that detected liquid can not be recognized is displayed on the display screen if the two groups of signal data are inconsistent. The method can avoid misinformation under the condition of detection condition insufficiency, and then a safer and more reliable detection effect can be achieved.
Description
[technical field]
The present invention relates to liquid field of detecting, especially relate to a kind of detection method of exempting to report by mistake liquid detection instrument of avoiding the wrong report liquid composition of surveying.
[background technology]
Known, owing to being subject to the impact of terrorist activity, in the time of the large-scale means of transports such as flow of the people intensive region, especially used during taking train, steamer and flight, more and more come into one's own for the safety check of dangerous material; Take liquid safety check as example, the liquid detecting instrument that detects at present liquid composition in airtight container comprises exploring antenna, processor, display screen and plastic casing; This detector is to utilize exploring antenna to obtain the signal of fluid to be measured, and being emitting electrode EO and the multiple fixing receiving electrode fixing by, exploring antenna forms, by fixing emitting electrode EO to electron emission or microwave signal in container, rely on again fixing receiving electrode that the electronics that in the container receiving, fluid to be measured is reflected back or microwave signal are transferred to processor, then by processor, signal is analyzed the composition of fluid to be measured in rear definite container; For example: the signal that the liquid of the low resistance such as water transmits on each receiving electrode of detector is basically identical, if the inflammable and explosive and poisonous liquid of the alcohol of high value, acetone, almost oil, various rosinol, nitroglycerine (explosive) or ether etc., the signal range of decrease on each receiving electrode of detector is direct ratio with the distance between this receiving electrode and emitting electrode so, this receiving electrode range transmission electrode is far away, and signal is just more weak so; According to this characteristic, as long as the liquid of the low resistance such as prior water has edited instrument, then just can carry out Treatment Analysis signal by the built-in algorithms of processor in instrument, thereby judge that whether the interior fluid to be measured of container is the dangerous liquid such as inflammable, explosive; But based on above-mentioned measurement characteristics, existing detector only just can normally be worked under two kinds of conditions: 1,1 can know and draw by reference to the accompanying drawings, the wall that the container of fluid to be measured is housed must be parallel with the electrode group of detector; 2, the fluid to be measured being equipped with in airtight container is wanted complete coated electrode group, and shown in accompanying drawing 4, being fluid to be measured does not have the situation of complete coated electrode group; If do not meet two kinds of above-mentioned measuring conditions, as while there is the situation that does not meet measuring condition as shown in accompanying drawing 2,3 or 4, that will cause and detect wrong measurement result, can accurately not detect the liquid composition in container, therefore, for inflammable and explosive and poisonous liquid, inaccurate due to testing result, virtually just drive green light to danger, when serious, very likely causing great social danger event.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention provides a kind of detection method of exempting to report by mistake liquid detection instrument, described method can be avoided wrong report in the time that testing conditions is not enough, thereby has reached safer reliable detection effect.
