Description

Technical Field

[0001] This utility model relates to the field of radiopharmaceutical production waste treatment technology, and in particular to a compact radiopharmaceutical production waste measurement device based on RFID. Background Technology

[0002] Solid waste and liquid waste generated after the production of radionuclides need to be collected and classified. In the past, the traditional method was manual processing. For example, after the solid waste was produced, the collector would use special waste collection bags or waste liquid storage containers, and then weigh it manually before it was put into storage. The weight was recorded manually, and then photos were taken and archived manually. The recipient would visually count the number of waste collection bags by checking the receipt record book, register and sign, and then measure the radiation dose rate on the surface. The data was recorded manually on a label and affixed before being stored in a special waste collection box in the warehouse.

[0003] Because the collection bags for the three wastes lack special methods of shielding against radioactivity, the process requires a long time of manual operation. If not handled in a timely manner, it increases the risk of secondary pollution, causing secondary radiation damage to personnel and even contaminating the work area.

[0004] While some existing technologies provide RFID-based material management technologies, such as Chinese patent CN203759746U which discloses an RFID-based radioactive source temporary storage management system, including: a radiation monitor, an RFID reader, an alarm, video surveillance equipment, and personnel access control equipment all connected to a server; RFID tags are placed on the outside of the radioactive source container, which is then placed on a load-bearing photographing device; the RFID tags are anti-metal RFID tags containing UHF FRAM RFID chips; the RFID reader is an RFID reader matched with the RFID tags. The load-bearing photographing device includes a load-bearing platform, a pressure sensor, a weighing controller, and a camera; the personnel access control equipment includes personnel access cards, an access card reader, and an automatic door.

[0005] Although the RFID tag-based radioactive source temporary storage management system can improve the processing efficiency of radioactive materials to some extent, the distance between its radiation meter dosimeter probe and weighing device is relatively far, and intermediate transfer is still required, resulting in low efficiency in the treatment of waste. Utility Model Content

[0006] The purpose of this invention is to provide a compact radiopharmaceutical production waste measurement device based on RFID to overcome the shortcomings of the existing technology.

[0007] The objective of this utility model can be achieved through the following technical solutions: A compact radiopharmaceutical production waste measurement device based on RFID includes an RFID reader, a radiation detector, a measurement host, a human-machine interface component, a weighing component, and a camera component. The RFID reader, radiation detector, weighing component, and camera component are all connected to the measurement host. The human-machine interface component is connected to the measurement host. The device also includes a camera component that corresponds one-to-one with the weighing component, and the radiation detector corresponds one-to-one with the weighing component. The RFID reader and radiation detector are mounted on the weighing assembly, the camera assembly is located on one side of the weighing assembly, and the display panels of the weighing assembly and the radiation detector are both facing the optical input end of the camera assembly.

[0008] The camera assembly includes a camera and a camera mount, with the camera mounted on the camera mount.

[0009] The camera bracket is a lifting bracket.

[0010] The weighing assembly includes a weighing platform, a mounting column, and a first display panel. One end of the mounting column is connected to the side of the outer shell of the weighing platform, and the first display panel is located on the other end of the mounting column. The mounting column is vertically arranged, and the RFID reader and radiation detector are both mounted on the mounting column.

[0011] The projection of the mounting column on the horizontal plane is located on the first central axis of the weighing platform. The projection of the weighing platform on the horizontal plane is a rectangle, and the first central axis is parallel to the long side of the rectangle. The projections of the RFID reader and the radiation detector on the water surface are located on both sides of the first central axis.

[0012] The weighing platform, mounting column, and first display panel together form a platform scale.

[0013] The weighing assembly also includes a container barrel, which is fixed to the weighing platform, and the RFID reader and radiation detector are disposed near the outer surface of the side wall of the container barrel.

[0014] The diameter of the container gradually decreases from top to bottom.

[0015] The measurement host is a PC.

[0016] The human-computer interaction components include a monitor and a keyboard and mouse.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up camera components and radiation detectors that correspond one-to-one with the weighing components, a data acquisition system centered on the weighing components is constructed. On the one hand, the weighing components sense and determine whether there is waste. On the other hand, the RFID reader identifies the waste information, and the radiation detector measures the radiation dose rate of the surface. Weighing, information identification, and radiation dose rate are all completed at the weighing components, which greatly improves processing efficiency and eliminates the need for long-distance turnover and movement.

[0018] 2. Based on the platform scale, a weighing component is constructed. The RFID reader and radiation detector are installed on the platform scale's mounting columns, which simplifies the modification process. Furthermore, by placing the RFID reader and radiation detector on both sides, sufficient space can be maintained to accommodate the waste, allowing the RFID reader and radiation detector to be positioned closer to the waste, thereby improving the success rate of information reading and radiation dose rate measurement.

[0019] 3. Configure containers with a diameter that gradually decreases from top to bottom to facilitate the prevention and removal of waste, thereby improving processing efficiency. Attached Figure Description

This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] A compact RFID-based device for measuring waste from radiopharmaceutical production, such as... Figure 1 As shown, the device includes an RFID reader 7, a radiation detector 6, a measuring host 1, a human-machine interaction component 2, a weighing component, and a camera component. The RFID reader 7, radiation detector 6, weighing component, and camera component are all connected to the measuring host 1. The human-machine interaction component 2 is connected to the measuring host 1. The device also includes a camera component that corresponds to the weighing component, and the radiation detector 6 corresponds to the weighing component. The RFID reader 7 and the radiation detector 6 are mounted on the weighing assembly, and the camera assembly is located on one side of the weighing assembly. The display panels of the weighing assembly and the radiation detector 6 are both positioned facing the optical input end of the camera assembly.

[0028] By setting up camera components and radiation detectors that correspond one-to-one with the weighing components, a data acquisition system centered on the weighing process is constructed. On the one hand, the weighing components sense and determine whether there is waste. On the other hand, the RFID reader identifies waste information, and the radiation detector measures the radiation dose rate of the surface. Weighing, information identification, and radiation dose rate measurement are all completed at the weighing components, which greatly improves processing efficiency and eliminates the need for long-distance turnover and movement.

[0029] In this embodiment, the camera assembly includes a camera 8 and a camera bracket 9. The camera 8 is mounted on the camera bracket 9. The field of view of the camera 8 can be large enough, for example, a wide-angle camera can be used, to ensure that the display panel of the weighing component and the radiation detector 6 can be captured simultaneously. In addition, to improve adaptability, the camera bracket 9 can be a lifting bracket; specifically, some existing tripods can be purchased.

[0030] In this embodiment, the weighing assembly includes a weighing platform 3, a mounting column 4, and a first display panel 5. One end of the mounting column 4 is connected to the side of the outer shell of the weighing platform 3, and the first display panel 5 is located on the other end of the mounting column 4. The weighing platform 3, the mounting column 4, and the first display panel 5 together form a platform scale. The mounting column 4 is vertically arranged, allowing for modification of existing platform scales by mounting both the RFID reader 7 and the radiation detector 6 on the mounting column 4. The projection of the mounting column 4 onto the horizontal plane is located on the first central axis of the weighing platform 3, and the projection of the weighing platform 3 onto the horizontal plane is rectangular, with the first central axis parallel to the long side of the rectangle. The projections of the RFID reader 7 and the radiation detector 6 onto the water surface are located on either side of the first central axis.

[0031] The weighing assembly is built based on the platform scale. The RFID reader 7 and radiation detector 6 are installed on the platform scale's mounting column, which simplifies the modification process. Furthermore, by placing the RFID reader 7 and radiation detector 6 on both sides, the RFID reader 7 and radiation detector 6 can be positioned closer to the waste while maintaining sufficient space to accommodate the waste, thereby improving the success rate of information reading and radiation dose rate measurement.

[0032] In addition, in some other embodiments, the weighing assembly also includes a container 10, which is fixed on the weighing platform 3. An RFID reader 7 and a radiation detector 6 are disposed near the outer surface of the side wall of the container 10, and the diameter of the container 10 gradually decreases from top to bottom, which facilitates the prevention and removal of waste and can improve processing efficiency.

[0033] In addition, in some embodiments, the measurement host 1 is a PC, and the human-computer interaction component 2 includes a monitor and a keyboard and mouse, which can reduce costs. The measurement host 1 can be an existing measurement host without modification. The photos taken by the camera 8 will be directly imported into the measurement host. Specifically, the camera 8 can be connected to the measurement host via USB and send the photos to the measurement host 1. The camera 8 can be an existing camera that supports USB or other connection methods. Since it is prior art, in order to avoid obscuring the purpose of this invention, it will not be described in detail.
