Abstract
Description
Technical Field
[0001] The invention belongs to detection technology, and in particular relates to a radiation source safety detection device. Background Art
[0002] A radioactive source is a general term for a radiation source made of radioactive materials. The strength of a radioactive source is generally marked by the activity of the radioactive nuclides it is made of, or by the ray emission rate or the injection rate. It is customary to refer to high-activity or high-ray emission rate radioactive sources used in non-destructive testing, radiotherapy, and radiation treatment as radiation sources.
[0003] The existing radioactive source library adopts the "two-person, two-lock" method. The work in the source library is repetitive and cumbersome, and there is no technical means to detect the radioactive sources. The safety detection device for entering and exiting the radioactive source library replaces manpower with detection, realizes the detection record of the radioactive source and human-computer dialogue, minimizes human risks, and improves the reliability and scientificity of radioactive source detection. The safety detection device for entering and exiting the radioactive source library is a transformation and improvement of the existing "two-person, two-lock" method of the radioactive source library. Summary of the invention
[0004] The purpose of the present invention is to provide a safety detection device for entering and exiting a radioactive source library, which can effectively improve the safety and traceability of the entry and exit of radioactive sources and ensure the rational and normal use of radioactive sources.

[0007] The PC is provided with two serial communication interfaces, the single-chip microcomputer controller is provided with three interfaces, and the gate circuit is provided with two input ends and one output end; the output end of the bar code information entry device is connected to a serial communication interface of the PC, and another serial communication interface of the PC is connected to an interface of the single-chip microcomputer controller. The other two interfaces of the single-chip microcomputer controller, one interface is connected to the GM tube detector II, and the other is connected to the output end of the gate circuit; one of the two input ends of the gate circuit is connected to the GM tube detector I, and the other is connected to the metal detector.
[0008] The barcode information input device is a barcode scanner.
[0009] The GM tube detector I is arranged inside the radiation source library, and the GM tube detector II is arranged outside the radiation source library.
[0010] The three interfaces of the single chip microcomputer controller are serial communication 232, interrupt 0 and interrupt 1 respectively.
[0011] The two input terminals and one output terminal of the gate circuit are receiving signal 1, receiving signal 2 and interrupt 0 respectively.
[0012] The two serial communication interfaces of the PC are USB ports respectively.
[0013] The two serial communication interfaces of the PC are USB ports, which are respectively connected to the serial communication 232 interfaces of the barcode scanner and the single-chip controller. The interrupt 1 interface of the single-chip controller is connected to the GM tube detector II, and the interrupt 0 interface of the single-chip controller is connected to the interrupt 0 interface of the gate circuit. Among the two input ends of the gate circuit, the receiving signal 1 interface is connected to the metal detector, and the receiving signal 2 interface is connected to the GM tube detector I.
[0014] The significant effects of the present invention are as follows: the barcode scanner is designed to have one-to-one corresponding codes and identity information for each radioactive source, which improves the ability to identify the entry and exit of the radioactive source; the two GM tube detectors enable the entry and exit of the radioactive source to have direction identification and detection capabilities, and the metal detector is used to detect the radioactive source shielded by metal; the PC is used as the control core, so that the borrowing or returning of the radioactive source has a human-computer dialogue function, which improves the use and recording functions of the radioactive source, improves the intelligence level of the device, and avoids the influence of human factors. The device has a simple structure, is easy and safe to operate, and reduces the influence of human factors. BRIEF DESCRIPTION OF THE DRAWINGS
