Description
Technical field
Information detection technology of the present invention field, refer to a kind of burglarproof alarming handset for radioactive sources that comprises the functions such as radiation dose detects, the RFID electronic labeling information reads, wireless data is uploaded especially.
Background technology
Radioactive source has important application in science, industrial or agricultural, medical science, generally concentrate on the units such as hospital radiological department, scientific research institution (colleges and universities or scientific research and testing chamber, atomic energy research institute), industrial enterprise's (paper mill, smeltery, metal factory, electric power enterprise), institutes of agricultural sciences (breeding base).But the ray that radioactive source emits has certain energy, and it can destroy cell tissue, and is heavy dead, the human body of gently hurting sb.'s feelings.70～eighties of eighties of last century, 45 radioactive accidents were just arranged in average 1 year.According to the statistics of the Ministry of Public Health, China's Mainland occurred altogether from 1988 to 1998 radioactive accident 332, exposure total number of persons 966 people.Wherein, the radioactive sources lost accident accounts for eighty per cant, loses 584 pieces of radioactive sources, has 256 pieces to fail to give for change.In recent years, environmental administration has strengthened management to radioactive source, but the radioactive source accident is still more.Therefore strengthen the Monitoring and supervision of radioactive source has been become an important topic of environmental administration.
At present, in the radioactive source Managed Solution, representative achievement is as follows:
1, patent of invention " radioactive source remote supervision system and method " (application number: 200710067854.1) propose to utilize the humiture information of radio sensor network monitoring perception radioactive source and environment thereof, and by public communication network, data are delivered to management control center.
2, patent of invention " a kind of to radioactive source automatically the method and system of supervision and Real Time Monitoring " (application number: 200810056795.2) propose the locating terminal that comprises GPS and CDMA is installed on radioactive source, judge that the position of radioactive source is whether in tolerance band.
3, patent of invention " radioactive source alarming, location, tracking system device " (application number: 200910067524.1) propose the tracker that comprises GSM mobile module, GPS module and RFID module etc. is installed on radioactive source, send alarm signal by GSM when tracker leaves certain limit.
4, utility model patent " radioactive source monitoring management platform " (application number: 200920110319.4) propose, by video monitoring and locating and monitoring, radiation dose being monitored the method for combination, radioactive source to be carried out remote real-time monitoring.
5, patent of invention " a kind of radioactive source monitoring system " (application number: 201010200429.7) proposed radioactive source monitoring system when using the external communication electrical network as power supply, also needed to carry out AC dump and detect and power alarm.
Above-mentioned technology path of benefiting our pursuits is correct, but has certain limitation, need to be further improved.At first, these systems, all take remote monitoring as main, lack on-the-spot inspection function.And on-the-spot patrolling and examining is the important ring that enterprise and environmental administration manage radioactive source, and regular visit is the embodiment to the radioactive source ability to supervise.When site administrator or the inspection personnel of Environmental Protection Agency need to confirm this scene radioactive source, these systems were all more unable.Secondly, be subjected to the restriction of working site wiring environment, the detector of most systems all adopts wireless mode to be arranged on radioactive source, but the detector volume is larger, have any problem with the radioactive source close installation, and failing to report, may appear in the warning when the shortage detector separates with radioactive source, has potential safety hazard.The matching used RFID active electronic label of this burglarproof alarming handset for radioactive sources volume is little, and has anti-tear-off function, in case label is torn from radioactive source, hand-held set will be received alarm signal.Finally,, although some systems have the radiation dose measuring ability, all be arranged on fixed position, can't meet the needs that the work on the spot environmental radiation dose moved detection.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, proposed a kind of burglarproof alarming handset for radioactive sources.This hand-held set meets patrols and examines to the radioactive source scene needs that detect with the operational environment radiation dose, has label and is torn the function of warning; Can either work alone, also can carry out data upload by the GPRS function of hand-held set, with radioactive source monitoring management platform, achieve a butt joint.
