Description
Technical field
The utility model relates to the technical field to radioactive matter monitoring, particularly the monitoring device that the vehicle radiomaterial is located.
Background technology
In the prior art, the YANTAR-1/2ZH train monitoring system of Aspect company for example, mainly be when radiomaterial is passed through, the gamma that it is launched monitoring of neutron or/and neutron ray causes that the ANOMALOUS VARIATIONS of system counts rate realizes gamma, thus learn whether the checking matter that passes through contains radiomaterial.This equipment can only provide the checking matter that passes through and whether contain radiomaterial, and can not provide the positional information at radiomaterial place, applicable to checking people and the automobile that passes through at a slow speed.When the vehicle that is applied to pass through fast, owing to there is not positioning system, will carry out one one investigation to vehicle, after determining to be a certain vehicle, carry out the search in the railway carriage again.And the most normal in actual applications monitored container reaches 18 meters, and is then longer for train, especially also will determine upper strata or lower floor for two-layer vehicle, and these all need to expend a large amount of time and manpower.
Summary of the invention
At the shortcoming that exists in the above-mentioned prior art, the purpose of this utility model provides a kind of monitoring device to vehicle radiomaterial location.It in conjunction with speed detection and image monitoring technology, determines the positional information of radiomaterial place vehicle in the on-line monitoring of finishing radiomaterial, thereby conveniently finds the radiomaterial in the vehicle.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of monitoring device to vehicle radiomaterial location, be included in the symmetrically arranged pedestal in road both sides and the ray detector, electronic control cabinet and the audible-visual annunciator that are installed on each pedestal, its design feature is the speed detector that it also comprises the camera that is installed in the image monitoring system on the pedestal and places base bottom two to survey.
In above-mentioned device, described ray detector comprises gamma detector and neutron detector.
In above-mentioned device, described gamma detector and neutron detector adopt many groups, and homeotropic alignment is at the medial surface of each pedestal.
Compare with prior art, the utility model is owing to increased speed detection and image monitoring function, in conjunction with the method for perpendicular positioning and horizontal location, can conveniently determine the vehicle and the particular location at radiomaterial place, be convenient to it is carried out next step isolation and processing.Significantly reduce detection time, saved hand labor.
Below in conjunction with accompanying drawing concrete embodiment is further described.

Embodiment
Referring to Fig. 1 to Fig. 4, device of the present utility model is included in the symmetrically arranged pedestal 1 in road both sides and the neutron detector 2, gamma detector 6, electronic control cabinet 4, audible-visual annunciator 7, camera 3, the speed detector 5 that are installed on the pedestal 1, and the step in concrete the use is:
1. to the energising of the utility model device, ray detector is that neutron detector 2 and gamma detector 6 will enter acquisition state automatically after initialization.Because airborne ray is in the process of continuously bombarding atmosphere and environment, incide ray detector thereby energy loss takes place, this part energy is converted into electric impulse signal output, signal is gathered and handled according to the principle of Fig. 5 by electronic control cabinet 4, the umber of pulse that writes down in unit interval is designated as background counting rate, and camera 3 enters monitored state simultaneously.
2. as shown in Figure 6, to be light transfer characteristics of utilizing infrared receiver device be converted into the electric impulse signal with corresponding temporal information with the velocity information of tested vehicle to speed detector 5.When vehicle through the infrared speed measuring device of speed detector 5 for the moment, infrared speed measuring device one has an impulse response, notes the moment T1 of this impulse response; When vehicle during through the infrared speed measuring device two of speed detector 5, infrared speed measuring device two also has an impulse response, notes the moment T2 of this impulse response.Because the distance of two groups of infrared speed measuring devices is known as L, and, can suppose that vehicle is uniform motion in this segment distance, can obtain the movement velocity V=L/ (T2-T1) of vehicle because L is less.
3. the gamma of the leakage of the radiomaterial in the vehicle is or/and neutron ray, inciding ray detector is that gamma detector 6 is or/and in the neutron detector 2, gather the pulse signal of ray detector output in real time and count according to the principle of Fig. 5, when surpassing the counting rate threshold values, send alerting signal through the gross-count rate after pre-service and the statistics.
4. alerting signal is recorded a video by the camera 3 that control interface sends image monitoring system to, and the image of 30s had also been preserved before camera 3 will begin to record a video, and simultaneously alarm command is sent to audible-visual annunciator 7 and reports to the police.
5. local computer carries out horizontal location in conjunction with the result of above-mentioned radioactivity prospecting, speed detection and Image Acquisition to radiomaterial.
When the tested vehicle that passes through is a dilly, car length more in short-term, can utilize the Ts constantly that passes through of radiomaterial that ray detector detects, from the consecutive image that the camera 3 of image monitoring system is recorded to, extract this and constantly discern by the picture of vehicle.
When the tested vehicle compartment is very long, the vehicle that the vehicle that utilizes speed detector to provide arrives initial moment T1, calculate this moment the radiomaterial that detects of speed V and ray detector by Ts constantly, just can obtain radiomaterial conceal the position horizontal direction from headstock apart from S=V * (Ts-T1).
6. to determine also that for two-layer vehicle radiomaterial conceals on the upper strata or lower floor,, radiomaterial be carried out perpendicular positioning by the result of local computer in conjunction with above-mentioned radioactivity prospecting, speed detection and Image Acquisition.The perpendicular positioning mode adopts in vertical direction and places two or three groups of gamma detectors 6 and neutron detector 2, is divided into two groups of homeotropic alignments.When radiomaterial with differing heights by the time, the counting rate that the gamma detector 6 of vertical direction and neutron detector 2 record in conjunction with the consideration to every group of radioactivity seeker inconsistency, is finished the location of vertical direction than different.
