Abstract
The utility model relates to a security detector, specifically a multi-sensor instrument for detecting a liquid hazardous article through data fusion. The problems to be solves and existing in the background technology are that a bigger measurement error can happen to an applied method during measurement and the detection accuracy can be affected because the thicknesses and shapes of the bottoms of containers, especially, the centers, which have gaps with certain heights, of the bottoms of some containers. The main points of the technical scheme applied for solving the above problems lie in that the upper surface of the box body of the instrument is provided with a box cover; the box cover is provided with a detected container opening which consists of a chute and a positioning baffle plate sliding along the chute; the interior of the box body is provided with a detection emission source and two sensors receiving to-be-detected signals. The instrument provided by the utility model is used for the detection of the liquid hazardous article, and remarkably improves the accuracy.
Description
Technical field: the utility model relates to a kind of safety detecting instrument is the detector of a kind of multisensor and data fusion tracer liquid dangerous material specifically.
Background technology: dangerous liquid material detector is dangerous liquid material to be detected to the instrument of identification, in the safety check systems such as civil aviaton, railway, urban track traffic, all needs the liquid article that passenger is carried to detect under the state not breaking a seal.In existing multiple inspection method and equipment, microwave detection method is one of main method.What in microwave detection method, Detection accuracy was higher is ultra-wideband pulse microwave reflection, basic structure and the mode of the method instrument are: container is positioned on base, emissive source and single receiving sensor are placed in to base below, emissive source receives reflected signal to container bottom launched microwave pulse signal and by single receiving sensor, according to the amplitude difference that receives signal, differentiates different liquid.Existing problem is: because container bottom thickness is different, different, the container bottom center particularly having exists certain altitude space, and application the method can exist larger measuring error while measuring, and affects Detection accuracy.
Utility model content: the purpose of this utility model is exactly the detector that proposes a kind of multisensor and data fusion tracer liquid dangerous material, to solve background technology, exist: because container bottom thickness is different, different, there is certain altitude space in the container bottom center particularly having, can there is larger measuring error while measuring in application the method, affect the problem of Detection accuracy.Solving this technical problem adopted technical scheme is: the detector of a kind of multisensor and data fusion tracer liquid dangerous material, it is characterized in that, above detector casing, case lid is set, on case lid, offer by sliding tray and the tested container that forms along the positioning baffle that groove slides and export, in casing, arrange and detect emissive source and two reception measured signal sensors.Wherein, detect emissive source and two reception measured signal sensors formation 100-150 degree angles.The inner absorbing material of filling of casing and case lid.Detect emissive source and fluid to be measured container foremost between distance between 1 times of wavelength and 3 times of wavelength.Detection emissive source and two reception measured signal sensors are more than or equal to the antenna of 5dBi for gaining.A plurality of sensors receive signal from different positions, adjust a plurality of sensor phase of received signal consistent by phase shifter, make a plurality of sensors keep same phase place at merging point, and while carrying out data fusion, signal, with superimposed, strengthen and receives signal.
The beneficial effect that the utility model and background technology comparison have is: according to technique scheme, the mode that adopts single emitting source transmitting multisensor to receive detects measured signal, by be distributed in container difference towards a plurality of sensors receive signals and carry out data fusion, reduced due to container outer wall uneven thickness, or the difference of the measured signal that shape difference causes, has significantly improved the Detection accuracy of liquid safe detector.According to statistics, the single-shot list that the single-shot layouts of receiving that the present invention adopts and common microwave reflection adopt more is received layout and from 90%, is increased to 99% at Detection accuracy.In addition, by sticking absorbing material at instrument inwall, make its to external world electromagnetic environment have more intense antijamming capability, the data reliability of signal sensing system is significantly improved, data precision is from 10
-1the order of magnitude is increased to 10
-2the order of magnitude.Also have less demanding to liquid measure, only need the liquid that about 10cm is high just can Measurement accuracy, easily operate, quick and precisely.
Accompanying drawing explanation: Fig. 1 is the utility model external structure schematic diagram.Fig. 2 is the utility model inner structure schematic diagram.
