Abstract
The cigarette detecting and imaging equipment consists of a gamma ray source inside a shielding cover, an array detector collimated to the source, and a signal adoptor to connect the array detector and an image processing system, the gamma ray source is a Na or Cs radiation source, the array detector is a scintillator array comprising strontium iodide array, photoelectronic element array and filter optical filter in between or a multiple wire proportional chamber. The equipment can detect cigarette in running vahicle effectively and in real time.
Description
The present invention relates to cigarette detecting and imaging device in a kind of container.
Cigarette is the higher commodity of a kind of added value, generally by country it is carried out and specially buys monopoly system; But under the ordering about of sudden huge profits, still have a large amount of false smokes and smuggled cigarrete to come into the market through various channels, wherein one of reason is that the fraud smuggler often loads in mixture cigarette in the goods of lorry or in the container and transports, and this has caused great difficulty to looking in time to pay black smoke and it is hit effectively.The problem that goods in the container is detected for the scene of solving, a kind of vehicle-carried gamma ray digital radiation imaging mobile detection station and array detecting device thereof are disclosed in Chinese invention patent ublic specification of application CN 1197209A, this measuring station and device thereof comprise cobalt-60 or caesium-137 high specific activity gamma activity isotope radiographic source and cask flask thereof, before, back collimating apparatus, detector array, signal, image processing system and supervisory control desk, trailer mechanism and generating set etc., these the said equipments all are placed in can be by conventional tractor haul to same on-the-spot trailer.But the resolution of this measuring station and device thereof is not high, particularly can not survey effectively cigarette.
The purpose of this invention is to provide a kind of can be effectively to cigarette, cigarette detecting and imaging device in the container that cigarette in the container is surveyed especially.
For achieving the above object, cigarette detecting and imaging device is made up of the detector array that places gamma ray projector in the protective cover, collimate mutually with gamma ray projector, the signal adapter that connects detector array and image processing system in the container of the present invention, wherein gamma ray projector be sodium (
22Na) radiation source or caesium radiation source, scintillator arrays or the multiwire proportional chamber of detector array for constituting by the optical filter between strontium iodide array and optoelectronic component array and this two array.
As a further improvement on the present invention, optoelectronic component array is photomultiplier tube array or CCD (beam coupling device) element arrays or photodiode arrangement; Be equipped with the image correction processor that the velometer that is provided with gamma ray projector or detector array place matches in the image processing system.
After adopting such structure, because this hydrocarbon of cigarette is bigger to the gamma-ray decay of sodium or the emission of caesium radiation source, and the scintillator arrays that is made of strontium iodide or the multiwire proportional chamber that collimate mutually with sodium or caesium radiation source are responsive to the gamma-rays of sodium or the emission of caesium radiation source, so in the time of between the detected material that contains cigarette is through sodium or caesium radiation source and scintillator arrays or multiwire proportional chamber, then can be because of the difference of sweep object to the radiation source absorptance, and corresponding difference appears in the electric signal output of the luminous output of scintillator arrays or multiwire proportional chamber; Make the light signal of scintillator arrays output be transformed into electric signal with the juxtaposed optoelectronic component array of scintillator, the existence of the optical filter between two arrays, eliminated the interference of parasitic light to photovalve, these all provide indispensable precondition for subsequent image processing and pattern-recognition so that make accurate judgement, make it in numerous and disorderly measured object cigarette to be told effectively.Simultaneously, also the specific aim because of emissive source is stronger, thereby has reduced the manufacturing cost and use cost to whole device.Again because the selecting for use of velometer and image correction processor (can have commercial software accordingly now and realize correcting image), also make transmission, rotation and corresponding control system thereof need not be set, only utilize under the mobile voluntarily condition of lorry, just can directly detect effectively detected material, wherein the translational speed of detected material below 60 meter per seconds all can, and then reduced total cost significantly.
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a kind of basic structure synoptic diagram of the present invention.
Fig. 2 is through the detected cigarette image of the present invention.
As shown in Figure 1, the gamma ray projector 1 in the protective cover 2 is the sodium radiation source, and it collimates mutually with the detector array 5 of the opposite side of the container 3 that measured object 4 is housed.Detector array 5 is strontium iodide array 6, constitutes as the photomultiplier tube array of optoelectronic component array 8 and optical filter 7.Detector array 5 places also are provided with velometer 11, they all are electrically connected through signal adapter 9 and image processing system 10, image processing system 10 be one based on microcomputer, be built-in with the existing mature equipment that corresponding software function module such as Flame Image Process, pattern-recognition, image correction process constitutes.
During detection, the lorry that only needs to be stated from the container 3 on the vehicle in advancing or be loaded with measured object 4 passes between gamma ray projector 1 and detector array 5, at this moment, the gamma-rays that sends from sodium radiation source along continuous straight runs behind the shielding window collimation of protective cover 2 penetrates antetheca, measured object 4, container 3 rear walls of container 3, get on the strontium iodide array 6 through the collimating aperture on the detector array 5 then, make it luminous, this light is received and is converted to electric signal by photomultiplier tube array and exports after optical filter 7 is handled.Along with moving of container 3, when passing different measured objects 4, gamma-rays produces corresponding decay, thereby corresponding strong and weak variation of luminous also appearance of strontium iodide, last photomultiplier tube array is exported the corresponding simulating electric signal synchronously.Be transformed into digital signal after these analog electrical signals amplify it by signal adapter 9 and send into image processing system 10, generate the image and the output in real time synchronously of chimes of doom light signal of measured object 4 through it.If measured object 4 is a cigarette, the image of the treated generation in then detected back as shown in Figure 2, simultaneously, the present invention also sends the sound and light alarm signal immediately.
