Description

TECHNICAL FIELD

[0001] The present application relates to an access cabinet, in particular to a chemical medicine intelligent access cabinet based on RFID technology applied in the field of cabinet. BACKGROUND

[0002] The chemical medicine intelligent access cabinet based on radio frequency technology (RFID) integrates radio frequency identification, intelligent environment monitoring and automation control technology to build a digital management platform covering the whole process of chemical medicine. The system gives each piece of chemical medicine a unique electronic identity tag, which can record the location, inventory status, expiration date and usage track of the medicine in real time. It also integrates temperature and humidity control, volatile substance monitoring and multi-level permission authentication functions to ensure the safety and controllability of the storage environment of high-risk medicines. However, due to the significant differences in the nature of chemical medicines, which not only include strong corrosiveness, toxicity, high volatility and hygroscopicity, but also a large number of bulk solid granular medicines without pre-packaging treatment, traditional storage solutions rely on multiple sealed containers for physical isolation, resulting in the mechanical arm being able to access only in units of "sealed containers". This mode not only cannot meet the demand for precise and on-demand access to bulk granular medicines, but also may cause cross-contamination or environmental exposure risks due to frequent opening of sealed containers.

[0003] The existing patent with publication number CN210961018U discloses a real-time monitoring chemical medicine access management intelligent cabinet. It sets up a multi-layer object carrier with grooves and pressure sensors inside the cabinet body, equipped with a sliding test tube clamp connected by a sliding rail, and integrates an alarm lamp on the top cover, an air purifier and a condenser in the installation compartment. It also cooperates with the display screen, input keyboard and interface of the control panel to realize human-computer interaction, so that the system can accurately record the storage location and weight change information of the medicine, and facilitate users to quickly query and locate. At the same time, through the sealed environment control and intelligent monitoring device, it achieves the comprehensive management function of safe storage, environmental regulation and abnormal warning of packaged / bulk chemical medicines.

[0004] The existing patent with publication number CN116432673A discloses a chemical medicine intelligent cabinet based on radio frequency identification. It integrates an electronic tag, a main control module, a chemical medicine identification module equipped with an RFID reader and multiple antennas, a user identity authentication module and a touch liquid crystal screen on the cabinet body, and uses an electric control lock to control the cabinet door. This makes the system able to quickly and accurately identify the chemical medicine information in the cabinet through the RFID antenna, and complete user permission verification through the touch screen and identity authentication module, achieving the comprehensive function of improving the access efficiency of chemical medicines, strengthening safety control and realizing intelligent management.

It should be noted that the reducing pipe 36 is a vertical tube that is wide in the middle and narrow at both ends. In addition, the sealing block 37 and the feeding roller 34 work together to achieve a two-stage seal for the chemicals in the inner cylinder 31.

[0039] Please see Figure 8 The outer wall of the inner cylinder 31 is fixedly connected to a protruding ring 3101 that slides against the inner wall of the storage bottle 10. A mass sensor 32 is fixedly connected to the lower end of the protruding ring 3101. An installation ring 1001 that is fixedly connected to the lower end of the mass sensor 32 is fixedly connected to the inner wall of the storage bottle 10.

[0040] Specifically, the mass of the inner cylinder 31 is monitored in real time by the mass sensor 32. When obtaining chemicals, the total mass of the inner cylinder 31 and the raw materials inside, and the mass difference before and after the release of the raw materials, is the amount of raw materials taken. It should be noted that the upper ends of the storage bottle 10 and the inner cylinder 31 are respectively threaded with a top cover, which facilitates the filling of chemicals after the storage bottle 10 is taken out.

[0041] Please seeFigure 12 and Figure 13 The lower part and the upper part of the outer wall of the taking pipe 16 are respectively fixedly connected with a fixed ring one 1603 and a limiting ring 1605, the fixed ring one 1603 is fixedly connected with an electronic tag two 41, and the front end of the second clamping arm 15 is fixedly connected with a read-write device three 42 matched with the electronic tag two 41.

[0042] Specifically, the information of the chemical medicine taken is written on the electronic tag two 41 by the read-write device three 42, so that the personnel can obtain the information of the raw material in the taking pipe 16 when using the taking pipe 16, and the length of the taking pipe 16 inserted into the variable diameter pipe 36 is limited by the limiting ring 1605.

[0043] Please refer to Figure 2 The input end of the control module is further connected with a weighing module, the input end of the weighing module is connected with the mass sensor 32, the output end of the control module is further connected with a writing module, and the output end of the writing module is connected with the read-write device three 42.

[0044] Specifically, the mass of the taken raw material is obtained by the weighing module, and the type and mass of the taken chemical medicine are written into the electronic tag two 41 by the read-write device three 42, so that the personnel can identify the chemical medicine information of the taking pipe 16 subsequently.

[0045] Compared with the traditional storage cabinet, the inner cylinder 31 and the mass sensor 32 are arranged to monitor the mass of the chemical medicine in the inner cylinder 31 in real time, and the leakage of the inner cylinder 31 is judged, and specifically, for the volatile chemical medicine, when the inner cylinder 31 and the storage bottle 10 leak, the mass detected by the mass sensor 32 gradually decreases, for the water-absorbing chemical medicine, when the inner cylinder 31 and the storage bottle 10 leak, the moisture in the external air enters the inner cylinder 31 and contacts the chemical medicine, so that the chemical medicine becomes heavy; meanwhile, when the chemical medicine is taken, the mass of the chemical medicine in the inner cylinder 31 is detected by the mass sensor 32, and the taking amount of the chemical medicine is obtained, so that the inventory of the chemical medicine can be accurately managed, then the taking amount of the chemical medicine is written into the electronic tag two 41 by the read-write device three 42, so that the personnel can identify and obtain the type and mass of the chemical medicine of the taking pipe 16 subsequently, and the chemical medicine can be accurately taken.

[0046] Please refer to Figure 2 The input end of the control module is further connected with an input module, the input end of the input module is connected with a touch display screen fixed on the front side of the controller 5, and the output end of the control module is further connected with an alarm module.

[0047] Specifically, during the storage of the chemical medicine, when the mass sensor 32 detects that the mass of the chemical medicine changes abnormally, the alarm module sends an alarm instruction to remind the operator to handle in time.

[0048] In combination with the actual needs, the above-mentioned embodiments adopted by the present application are not limited thereto, various changes made within the knowledge of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
