Description
Technical field:
The present invention relates to online scanning-detecting system, particularly large-scale mobile object detection system.Belong to the Application of Nuclear Technology field.
Background technology:
In current society, encased conveying has developed into the main mode of modern shipping.The encased conveying amount of China is also very huge.Only port, land route, Shenzhen area container carrier of passing in and out every year is just above 8,000,000.Accompany therewith, utilize that container is smuggled, Traffic in Narcotic Drugs and transport illegal activities such as illegal weapons secretly and also be becoming increasingly rampant, become big public hazards of international community.
From the nineties in 20th century, container examination system is equipped various countries customs successively, and its principle is as follows: a side radioactive source produces ray, and relative one is sidelong and puts top-down detector array, places tested object (container carrier) between the two ends.Ray penetrates container and arrives detector array, because the tested object mass density difference of ray process, the transmitted intensity difference that detector array absorbs, thereby the signal difference on the sensor can constitute the one dimension image of tested object, the perspective two dimensional image that produces tested object along with the checkout equipment and the relative motion between the tested object of radiographic source and detector array one.
Present container examination system has two kinds of detection modes: checkout equipment is fixed, and drags sense channel to finish scanning tested object by the dragging system of special use, and this system is called fixed system, and its equipment takes up an area of big, and the dragging system complexity, the failure rate height; Another kind of tested object is motionless, finishes the scanning detection by the detecting unit motion that radioactive source and detector array form, and this system is less relatively owing to taking up an area of, and cost is lower, has obtained using more widely.All about 20-30/hour, what customs carried out is sampling observation to the detection efficiency of present two types container examination system, and smuggler has been played certain fright effect.
Along with economic development, the encased conveying amount increases day by day, and customs by accelerating the work flow IT application process, improves customs clearance efficiency for improving the speed of being open to the custom greatly, and the lorry of the Jian Ceing speed of being open to the custom has not reached 4.5 seconds/cars.The raising of the speed of being open to the custom has guaranteed that logistics is unimpeded, but also to customs the inspection of goods carrying vehicle has been brought bigger difficulty.
Existing container examination system can only carry out the off-line selective examination because detection efficiency is low excessively, can not satisfy the online detection needs that the lorry passage speeds passage through customs, and the detection system occupation of land is huge, can't arrange in the passage of port at all.So be badly in need of a kind of quick online detection equipment, testing process is simple, take up an area of for a short time, can carry out quick online detection to most of even the vehicle of all being open to the custom, guarantee neither to leak the smuggling lorry, do not influence the speed of being open to the custom of passage simultaneously again.
Summary of the invention:
The purpose of this invention is to provide online speedtainer detection method of a kind of suitable customs and device.To achieve the above object of the invention, technical scheme of the present invention realizes as follows: a kind of online container method for quick, not independent occupied ground, arrange following constituent element on be open to the custom passage at the port successively: IC-card read write line, ground induction coil, speed pickup, detecting unit, the IC-card read write line.Signal acquiring system, data handling system and display mounting are in the pulpit.Said detecting unit is a frame component across passage, on two columns of detecting unit frame component, radiation source and detector array are housed respectively, on two columns photoelectricity is housed also and cuts apart sensor, on a column of detecting unit frame component, video camera is housed.The IC-card read write line is used for reading the driver's of tested object integrated radiation dose, and ground induction coil is used for the arrival of the tested object vehicle of perception, the translational speed when speed pickup is used for recording tested object by detecting unit.Radiation source and detector array are used to provide the ray of the tested object of transmission and the ray that tested object is passed in reception.Photoelectricity is cut apart sensor and is used for the position in the tested object headstock of perception, compartment.
Container device for fast detecting of the present invention is made up of following constituent element: two IC-card read write lines, ground induction coil, speed pickup, detecting unit, pulpit.On above-mentioned constituent element is open to the custom passage according to following arranged in order at the port, an IC-card read write line, ground induction coil, speed pickup, detecting unit, another IC-card read write line.Outside the independent layout in pulpit is online.Detecting unit is a frame component across passage, on two columns on the detecting unit frame component, radiation source and detector array are housed respectively, photoelectricity also is housed respectively on two columns cuts apart sensor, on a column of detecting unit frame component, video camera is housed.Signal acquiring system is arranged in the pulpit, and it is one group of photoelectric sensor that data handling system and display, photoelectricity are cut apart sensor, and ground induction coil is a solenoid.
Testing process is: the driver driving lorry is to feeder connection, be parked in by the IC-card read write line, read in driver's IC-card data by the IC-card read write line, and whether the integrated radiation dose of differentiating the driver exceeds standard, if do not exceed standard, then continuing to drive lorry by the driver moves ahead, being arranged in the underground ground induction coil of detecting unit senses lorry and has arrived the sense channel mouth, the outward appearance video camera can be taken tested lorry outward appearance, speed pickup begins to measure the travel speed of tested lorry, continue in the driving process at tested lorry, headstock, compartment photoelectricity is cut apart sensor and is sensed the compartment automatically and arrived the detection position, can send signal, the order radiation source sends ray, and detector begins to gather ray signal; Local sense is coil-induced leave the detection position to tested lorry after, radiation source stops to send ray, detector and data gather computer stop acquired signal, and handle by the signal that image processing system will collect, signal according to speed pickup is proofreaied and correct image, proofreaies and correct good image and reaches display unit, and display unit shows the appearance images and the fluoroscopy images of production simultaneously, check that for the overlooker judgement is clearance or rechecks.Tested lorry then is parked in by second IC-card read write line by driver driving, reads in driver's IC-card data once more, writes down this time and detects the suffered radiation dose of driver.If finding when first IC-card read write line reads in driver information that this driver's integrated radiation dose has reached limits the quantity of, then do not detect or detect by changing customs's dedicated driver.
Because the present invention only sets up a detecting unit and some attached instrument on the customs declaration passage, it has cancelled the relative motion in present other container examination system testing processes, the substitute is by tested object autokinetic movement finish with the checkout equipment relative motion constitute another the dimension image, reduced system equipment, remove the required a large amount of maintenances of mechanism system simultaneously from, and only needed occupation of land seldom.This system and customs's container carrier declaration work flow combine together, thereby realize quick online detection.For reducing the suffered radiation dose of driver in the testing process, we adopt headstock compartment photoelectricity to cut apart sensor, and the system that makes does not detect the headstock at driver place, only begins to detect from container.We write down driver's the time of passing through and dose accumulation amount by the entrained IC-card of driver individual simultaneously, and for the driver sets up personal dose's archives, make driver's section integrated radiation dose of suffered unit interval be no more than public's personal radiation dose standard.We at first utilize read write line 7a that driver's IC-card is checked before lorry arrives detecting unit, if driver's integrated radiation dose exceeds standard, then do not detect, and directly let pass.IC-card read write line 7b behind detecting unit record driver at every turn by the time suffered radiation dose and accumulating.When the radiation in case the driver proposes and uncomfortable generation dispute, this equipment possessor has the proof condition.
According to technique scheme, can the lorry (as train) of orbital motion be detected equally, also belong to protection domain of the present invention.
