【摘要】 放射源产生的核辐射对人体的健康具有危害性,而放射源的丢失与被盗更会造成环境污染,引起社会恐慌。为了解决放射源的异常泄漏和意外丢失、被盗等问题,研制了基于RFID、GPS、GPRS和GSM等技术的放射源监控系统。辐射剂量检测仪和GPS无线定位模块分别实时获取放射源辐射剂量值与位置信息,RFID阅读器读取安装在放射源底部的电子标签状态信息。放射源辐射剂量值、位置与标签状态信息通过GPRS无线传输方式发送到远程监控中心。当辐射剂量超标或者放射源状态异常时,现场进行声光报警,同时监控中心通过GSM Modem向管理人员发送短信报警,从而实现对放射源的监控与报警。该系统投入运行效果良好,数据稳定可靠,报警准确,有效地提高了放射源的监管水平。更多还原

【Abstract】 Nuclear radiation produced by radioactive source is harmful to the health of human body,and the lost and theft of radioactive source will cause environmental pollution and social panic.In order to solve the abnormal leaks,accidental loss,theft and other problems of the radioactive source,a radioactive source monitoring system based on RFID,GPS,GPRS and GSM technology is put forward.Radiation dose detector and GPS wireless location module are used to obtain the information of radiation dose and location respectively,RFID reader reads the status of a tag fixed on the bottom of the radioactive source.All information is transmitted to the remote monitoring center via GPRS wireless transmission.There will be an audible and visual alarm when radiation dose is out of limits or the state of radioactive source is abnormal,and the monitoring center will send alarming text messages to the managers through GSM Modem at the same time.Thus,the functions of monitoring and alarming are achieved.The system has already been put into operation and is being kept in functional order.It can provide stable statistics as well as accurate alarm,improving the supervision of radioactive source effectively.更多还原
