Description

Technical Field

[0001] The utility model belongs to the field of medicine management of medical rescue vehicles, and particularly relates to an NFC medicine inventory system. Background Art

[0002] In the medical industry, medicines need to be counted in many scenarios, such as when performing medical rescue, it is necessary to count the medicines on the medical rescue vehicle to avoid missing or wrong medicines. The inventory counting methods used in the prior art mainly include the following: infrared detection, ultra-high frequency RFID detection and weighing. The disadvantages of these methods are that infrared has an impact on some medicines, and the inventory count is inaccurate; ultra-high frequency RFID is difficult to achieve point-to-point, the inventory count is inaccurate, and the cost is high; the weighing method is used for a long time, which will cause the sensor itself to drift and the inventory count is inaccurate. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide an NFC medicine inventory system, which can improve the efficiency and accuracy of medicine inventory.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] The utility model provides an NFC medicine inventory system, comprising a background controller unit, an NFC signal output unit, an NFC control unit, an antenna unit, and a medicine label unit. The background controller unit interacts with the NFC signal output unit, the NFC signal output unit interacts with the NFC control unit, the NFC control unit interacts with the antenna unit, and the antenna unit interacts with the medicine label unit.

[0006] Furthermore, each NFC control unit is connected to the NFC signal output unit via a signal line, and then interacts with the background controller unit via the CAN bus or 485 communication.

[0007] Furthermore, the antenna unit includes an antenna module and an indicator light module. The antenna module is connected to the indicator light module, and the drug label unit and the NFC control unit both interact with the antenna module.

[0008] Furthermore, the system also includes a human-machine interface unit, and the human-machine interface unit interacts with the background controller unit.

[0009] Furthermore, the system also includes an alarm unit, and the alarm unit and the background controller unit.

[0010] Furthermore, the system also includes a speech unit, and the speech unit interacts with the background controller unit.

[0011] Furthermore, the drug label units are provided in plurality, and the plurality of drug label units interact with one antenna unit.

[0012] In the present application, the label information of the drug label unit is identified by the antenna unit, and the label information is transmitted to the NFC control unit. The NFC control unit performs statistical comparison on the received label information, and transmits the information to the background controller unit through the NFC signal output unit. The background controller unit then performs statistical comparison information and gives it to the human-machine interface unit or the alarm unit and the voice unit. Similarly, when the human-machine interface unit issues an instruction, the background controller unit performs information comparison, and sends the instruction to the corresponding antenna unit through the NFC signal output unit and the NFC control unit, and then sends it to a certain drug label or multiple drug labels or indicator lights.

[0013] In the system, the IO port of an antenna unit is used to control multiple antennas. The drugs on the antenna are counted in a cyclic manner. The drugs are affixed with NFC tags and then transmitted to the background controller unit. The background controller unit and the human-machine interface unit deliver the drugs to the antenna for binding. By counting the tags bound to the antenna, the number of drugs can be counted. When a bound drug port leaves the bound antenna, the background controller unit promptly sends information to the human-machine interface to remind it, and at the same time sends it to the alarm unit to alarm. Similarly, when two bound drugs are swapped, timely reminders and alarms can be given. When rescuing and taking medicine, as long as the drug name is entered (the drug name is bound to the antenna and the tag) or the icon of the human-machine interface is clicked, the corresponding drug position will have an indicator light flashing, and there is no need to search. After taking out the medicine, there will be a voice reminder and the medicine taken away will be recorded, which saves medical staff time in finding medicine and tedious confirmation work.

[0014] Compared with the prior art: the NFC drug inventory system of the present application can find drugs in time during the rescue process, shorten the time consumption, and remind the drug outlet of expiring and expired drugs through signal interaction between the background controller unit, NFC signal output unit, NFC control unit, antenna unit, and drug tag unit, thereby improving the efficiency and accuracy of inventory. In addition, the inventory is performed through NFC single-core multi-antenna technology. One NFC antenna can recognize multiple NFC tags, making the inventory more accurate and the positioning more precise, and the location of the drugs can be known in real time.
