In system.It is intact in the information that dense ionization radiation environment chips are stored using the RFID chip of FRAM memory technologies, and base
It may be lost in the information that dense ionization radiation environment chips are stored in EEPROM common RFID.It is close in radioactive source storehouses
Envelope radioactive source is stored in close radiation source container, and container is mostly the canisters such as pig, iron flask, and minority is held for plastics
Device, therefore the anti-metal performance of the RFID tag of the invention used, having ensured can be read into all vessel surfaces.
2) outbound, storage differentiation technology:
To radioactive source outbound, storage differentiation can use two ways, one, monitor supervision platform statistic logic analysis, refer to figure
5:Each piece of radioactive source goes out when being put in storage, and system access goes out to be put in storage reading times, enters to read in storage from radioactive source first and is counted as
1,2 are counted as during discrepancy, the like, go out to be put in storage number of times odd number system and think storage, even numbers is outbound, and discrepancy is read every time
During the radioactive source label of storehouse, the archives deposited according to system judge to come in and go out or are put in storage that authoring system client can periodically check discrepancy
Storehouse information, if any it is special go out warehouse situation cause outbound storage conversely can system call interception.2nd, two sets of card reader logic analyses, in detail
See Fig. 6 and Fig. 7:Wherein card reader judgment mode refers to Fig. 6;If detecting that card reader is A and card reader B outdoors in door, A reads mark
B reads label and then represents outbound after label;B, which reads A after label and reads this piece of label, then represents storage, and A, B card reader passes through metal
Baffle plate is separated, and keep more than 20cm distances to exclude AB while reading the possibility of label.The class determination methods of the above two can reach
Come in and gone out the effect of reservoir area point, and in-site installation condition, selected producer's label and card reader are selected according to the characteristics of the storehouse of source.
(2) other radioactive source monitor modes:
The alarm of radioresistance anti-metal RFID REIDs and radiation dose monitoring, go out storage take pictures, video monitoring, people
The technologies such as member gate inhibition are combined, and are the total solution that radioactive source goes out to be put in storage automatic management Multi-azimuth monitoring, a variety of monitoring sides
Formula is integrated.
(1) Al Kut that comes in and goes out, which is write, takes pictures:When going out to be put in storage, sealed radioactive source container is placed on load-bearing by the personnel for getting radioactive source
On platform, pressure sensor or pressure switch receive pressure signal and transmit a signal to controller of taking pictures, and controller starts
Camera, camera is placed on tiltedly upper angle and is easy to take out storage radiation source container and label, numbering, label above etc., and
Filename storage photo is done with date, time, is easy to the later stage to check verification.Camera can even be removed with adjustment angle, be taken a picture
System is reserved to take pictures manually, is easy to remove camera when radiation source container is huge/heavy and takes pictures manually, camera system composition is shown in
Fig. 8, workflow is shown in Fig. 9.
(2) dose of radiation is monitored and alarmed in real time:The equipment includes radiation detector and controller.Radiation detector includes
Gamma detector and neutron detector, radiation detector measurement continuous radiation close rate data, controller passes through wired or wireless
Data are transmitted to prison with wired or wireless communication modes after mode and detector UNICOM, the Radiation monitoring data of controller collection
Control platform.Monitor supervision platform stores dose of radiation data, and alarm threshold value can be set on monitor supervision platform.Controller carries sound
Light crossing-signal, dose of radiation exceedes alarm threshold value then sound and light alarm;Radiation dose monitoring equipment framework such as Figure 10.
(3) personnel gate inhibition:The corresponding access card of personnel's ability only ratified by system, the access card ability only authorized
Open out storage gate or allow access into.After access card is swiped the card, system record title, unit company information and when going out to be put in storage
Between etc. information.Access card can use IC-card, fingerprint or password identification, this technology workflow such as Figure 11.
(4) video monitoring:It is made up of infrared camera, memory, processor, multi-display and circuit.Radioactive source storehouses are each
The video information of control point camera acquisition is transmitted separately to Surveillance center, the multiwindow on Surveillance center's video monitoring display
Show simultaneously, and real-time monitor video and history monitor video can be checked in system platform;Video monitoring system framework is as schemed
12。
(5) video interlink:Radioactive source is unauthorized to be gone out to be put in storage, radiates superthreshold startup warning system, starts video during alarm
Linkage, live video is actively ejected on monitoring center software platform, and the condition of video interlink and the number of windows of ejection can
Carry out system setting, this Software Function Design be easy to supervisor to source stock potential danger find, handle, work in time
Make flow such as Figure 13.
