Fig. 3 and Fig. 4 is the schematic diagram for describing inspection method according to the ... of the embodiment of the present invention, and wherein Fig. 4 is equipment shown in Fig. 3
Schematic top plan view.As shown in Figures 3 and 4, the equipment of quick-speed image-forming checking includes accelerator nacelle 309, and quick response light curtain is opened
Pass 302,305 and 306, ground induction coil 303 and 308, optoelectronic switch 310, protecting wall 304 and 311, velocity radar 307, detector
Several parts such as arm 312, control software.Quick response light curtain switch 302 is mounted on the installation column of channel both sides, ground induction coil
303 are embedded in first switch for vehicle entrance below the earth's surface of feeder connection, and protecting wall 304,311 is vertical to be mounted in channel both sides
And connected respectively with the accelerator nacelle 309 of channel both sides and detector arm 312, quick response light curtain switch 305,306 is installed
On the wall and detector arm 312 of the accelerator nacelle 309 of channel both sides, optoelectronic switch 310 is mounted on the anti-of channel both sides
On revetment 311, velocity radar 307 is mounted on accelerator nacelle 309 on the exterior wall in channel, and ground induction coil 308 is embedded in logical
It is partial to export direction under the earth's surface in road.The course of work of the present invention is as follows：
System is in standby when vehicle number is 0 in channel, the ground induction coil when a vehicle 301A is sailed to channel to be come
303 first effectively, and quick response light curtain switch 302 is combined to complete the differentiation to vehicle heading, if vehicle drives into channel
Then number of vehicles adds 1 in channel, and velocity radar 307 measures Vehicle Speed, and system enters ready state.Vehicle after
Continuous to move forward, system whole process records state change of the vehicle in the driving process of channel.
When vehicle with normal speed by 301A through 301B to 301C when optoelectronic switch 310 it is effective, switched at this time by light curtain
305 condition discrimination tested vehicle is container truck or closing lorry, and item is triggered using different scanning according to different automobile types
Part.
The equipment of the quick-speed image-forming checking can further include detector, in quick response light curtain switch 302
It detects that vehicle enters after inspection area, if the condition discrimination of above-mentioned light curtain switch 305 is container truck, starts to detect
The driver's cabin of vehicle whether by and generate through signal, then be scanned inspection when container reaches inspection area.Wherein
The control system is generated according to being sent out from the detector through signal for controlling the betatron system
Generate the control signal of electron beam.
When vehicle travels out scan channel, vehicle count subtracts 1 in channel.As long as vehicle fleet size is not 0 in channel, system is protected
It holds in ready state；When vehicle fleet size is 0 in channel, system enters standby mode.
In an embodiment of the present invention, when the sensor of Channel front end, such as ground induction coil 303 and light curtain switch 302 are examined
When having measured vehicle and entering channel, the betatron that control device 105 controls in scanned imagery device powers on, sense electronics
The electron gun of accelerator is answered to generate electron beam, the electron beam of generation is injected among the rotary track of magnet winding composition, to this
It is accelerated.After accelerating to scheduled electron energy, such as after accelerating to several M electron volts, by deflect winding will plus
The electron beam of speed is drawn, and target is bombarded, and generates X-ray.During acceleration, Kang Te pulls around group and gathers to electron beam, prevents
Only electron beam divergence.
In the above-described embodiments, above-mentioned switch 302 can be formed as the first quick response light curtain switch, will be above-mentioned
Switch 305 is formed as the second quick response light curtain switch, and above-mentioned switch 306 is formed as third quick response light curtain switch,
Above-mentioned switch 310 is formed as into optoelectronic switch.In other embodiments, which can also be with another quick response light
Curtain switch is used together.
In some embodiments, second position sensor detects the type feature of the mobile target and distinguishes mobile target
Protected portion and non-protected portion, will mobile target segment, output transducing signal shows being protected for the mobile target
Shield part by or passed through radiation scanning area.Such as, it can be determined that the type of mobile target is container truck, compartment
Formula lorry etc., and according to the scan mode of vehicle progress predefined type.For example, in the case where determination is motor bus, no
It is scanned with to vehicle, if it is closed truck, then carries out out beam scanning.If it is container truck, then delay is certain
Time after go out beam scanning when vehicle head part is driven out to radiation scanning area and container reaches radiation scanning area.Alternatively, for collection
The vehicle head part of vanning truck uses the X-ray beam of the first energy, and the X-ray beam of the second energy is used for con-tainer part,
First energy is that the about one third of the second energy is even lower.
In this way, after vehicle is divided into different sections, control unit detects not same district in second position sensor
When section is by the radiation scanning area, controls the betatron and go out Shu Shidian and go out beam pattern to each of mobile target
A section is checked accordingly, and corrects scan image data according to speed.
For example, in some embodiments, under carrying out driver not for car, motor bus, container truck, cargo
The scanning of full vehicle or sectional scanning that vehicle drives through.For another example, second position sensor is also configured to detect and differentiate non-vehicle
, car, motor bus, trailer-type container truck, cargo.
Since switching time of the betatron between different operating sequential is very short, so control unit can be with
Instruction is sent out according to the transducing signal of second position sensor, to switch the work of the deflection coil of the betatron
Make sequential, generates the X-ray beam of different-energy.For example, by the way that different work schedules is arranged, shielded part can be directed to
Such as cockpit uses the X-ray beam of the first energy, and the X-ray beam of the second energy is used for unprotected part, this
One energy is that the about one third of the second energy is even lower.In this way, can be with different scan patterns to mobile vehicle
Different sections be scanned.For example, in the case where it is 7.5MeV that the first energy, which is the second energy of 2.5MeV, cockpit receives
Exposure dose be about container receive exposure dose 3 percent, therefore in this case driver do not have to get off
It can also be checked.
In other embodiments, control unit is pacified according to the transducing signal of sensor with different working methods
Inspection.Such as be continuously lined up in the continous way work for carrying out safety check in vehicle, betatron can be in standby mode and work
Make state switching.For another example, under service intermittent mode, vehicle is few sparse when passing through safety check, and betatron can
To switch between non-power-up state powering on.
Scheme in accordance with some embodiments checked during vehicle is advanced, and is not needed driver and conductor and is got off and sets
It is standby controlled when the mobile target passes through scanning area accelerator with the response speed being exceedingly fast emit the beam of corresponding energy into
