Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example 1
The embodiment provides a method for checking shelf items based on RFID, and a structural schematic diagram of a system for checking shelf items using the method is shown in fig. 1, where the shelf is divided into at least 1 specific area 101, the shelf is provided with a checking trigger device 105, and further includes an RFID antenna 103 arranged in the specific area, a pickup trigger device 102 arranged at an opening of the specific area, a reading device 104 in communication connection with the RFID antenna 103, and a main control device 106 in communication connection with the pickup trigger device 102, the checking trigger device 105, and the reading device 104. In this embodiment, a plurality of RFID antennas 103 are provided in the specific area. The goods taking triggering device (102) arranged at the opening of the specific area is a grating sensor or a camera and covers the opening of the specific area. The inventory trigger device (105) is triggered by a key and/or light.
The flowchart of the inventory method provided in this embodiment is shown in fig. 2, and is performed according to the following steps:
s1, the main control device 106 receives the trigger signal sent by the trigger apparatus 102, and stores the number of the specific area 101 corresponding to the trigger apparatus 102 in the to-be-checked list. Structure diagram of data storage by master control device a structure diagram of data storage by master control device is shown in fig. 3.
S2, the main control device 106 receives the inventory signal sent by the inventory trigger device 105, and if the number of the specific area 101 exists in the to-be-inventory list, sends the number to the reading device 104.
S3, the reading device 104 communicates with the RFID antenna 103 corresponding to the number of the specific area 101, and counts the EPC number of the RFID tag corresponding to the RFID antenna 103. When the number of the RFID antennas 103 is plural, the RFID antennas are sequentially checked.
When the number of the RFID tags is checked, the checking stopping condition is any one of the following conditions:
(1) when preset counting time T is reached, the counting time T is n x T, wherein n is the number of the RFID tags corresponding to each RFID antenna 103, and T is the counting time of each tag;
(2) the number of EPCs corresponding to the RFID antenna 103 of the inventory has reached a preset value corresponding to this RFID antenna 103.
The application scenario of the inventory method of the invention is as follows:
in hospitals, a high-value consumable supply warehouse is provided, a plurality of high-value medical consumable supplies are stored in the warehouse, the consumable supplies are mainly prepared for patients in operations, and the consumable supplies are placed on shelves. There are typically tens of storage levels, and each item is tagged with an ultra-high frequency RFID tag for ease of inventory and settlement.
Before an operation, each nurse can enter a high-value consumable warehouse through an access control system. To ensure accuracy, only one nurse can be admitted at a time. After the nurse takes away the required consumptive material from the storehouse, close the door in consumptive material storehouse, the consumptive material storehouse is automatic to carry out RFID and checks. Due to the large number of RFID tags in the consumable library, the inventory time is usually long, and sometimes it may be more than 1 minute. Only after the inventory is completed is the second nurse admitted.
Due to the low efficiency of total inventory and the high error rate, the preparation time of the operation in the morning is long, a lot of nurses wait in line, and the operation is delayed sometimes.
In addition, temporary high-value consumables need to be taken during the operation, so that more accurate checking and settlement are needed, and the operation can be performed smoothly.
In this embodiment, checking trigger device 105 sets up at entrance guard's mouth, the goods shelves of high value consumptive material divide into a plurality of specific regions 101, set up a plurality of RFID antennas 103 in every specific region, every specific region opening part sets up gets goods trigger device 102, after the nurse got high value consumptive material from the goods shelves, can trigger and get goods trigger device 102, the system can remember the specific region 101 of getting goods, leave the back when the nurse, trigger and set up in entrance guard's mouth's checking trigger device 105, only check this specific region 101 of getting goods, and need not check all goods shelves, checking efficiency can improve greatly like this, the setting can accomplish the settlement of checking within 2 seconds, great saving the time of checking.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
