Application scenarios of RFID devices in primary school laboratory management systems

RFID technology, with the development of information technology and manufacturing technology, is becoming increasingly perfect. It has the advantages of low threshold, low cost, high efficiency, and high security, and is one of the key technologies to achieve the Internet of Things. At present, the management methods of some primary and secondary school laboratories still lag behind the pace of scientific and technological development. Therefore, it is necessary to use RFID technology to develop an intelligent laboratory management system, in order to thoroughly improve some outdated laboratory management methods in primary and secondary schools.

 

1. Inventory check

The use of RFID technology for inventory and inventory of instruments and equipment in the instrument room is the most important and successful application of RFID technology. When using a handheld reader for inventory, electronic tags of instruments and equipment within a radius of 6 meters from the handheld reader can achieve batch recognition in seconds, without the need for manual input or scanning, thus quickly, accurately, and automatically identifying the instruments and equipment in the entire room. Compare the identification results with the system inventory and export an inventory report. Compared to manual inventory and barcode (two-dimensional code) scanning recognition, it shortens inventory time, reduces labor intensity, improves inventory efficiency, reduces error rates, realizes intelligence and automation of inventory inventory, and completely solves problems such as discrepancies between accounts, items, and cards in asset management.

 

2. Valuable asset management

(1) When movable valuable assets (such as computers, cameras, etc.) pass through a fixed access control reader, the reader can 100% recognize and read the device label information, and the system automatically records the entry and exit information of valuable assets.

(2) When valuable assets enter or exit abnormally, the access control point will sound and light an alarm, and the electronic tag will sound and light an alarm. The background will record abnormal entry and exit records, and the video monitoring system will activate emergency recording.

(3) The electronic tags for valuable assets also have anti metal and anti dismantling alarm functions, which can further prevent the loss of valuable assets.

3. Experimental management

(1) When students enter the laboratory for group experiments, the school badge with RFID electronic tags is immediately recognized by the access control reader. The experimental management system automatically collects information such as student names, classes, and experimental groups, and generates attendance records.

(2) During the experiment, the teacher uses a handheld reader to quickly identify the instruments and equipment in the laboratory, and can quickly understand the usage of laboratory instruments and equipment.

 

4. Instrument lending

When borrowing instruments and equipment, teachers or students can fill out and upload the instrument borrowing list on mobile devices such as mobile phones and tablets.

After retrieving the instruments and equipment, use a reader to quickly identify the information of all borrowed instruments and equipment, and automatically enter the borrowed data.

When returning, the reader is also used to read the returned device information, without the need for laboratory administrators to manually count, input, and check.

 

5. Management decisions

At present, some primary and secondary school laboratories are in a primitive manual mode of management, manifested as: firstly, disorderly placement of instruments and equipment, unclear classification, and discrepancies between accounts and materials. The second issue is that the experiments were conducted incompletely and incompletely, with low success rates. The usage of group experiments and demonstration experiments was manually recorded and counted, and there were even fraudulent behaviors such as forging experimental reports to cope with superior inspections and not conducting experiments, which could not truly and accurately reflect the usage rate of instruments and equipment. The third issue is inaccurate statistics when purchasing and supplementing instruments and equipment, lack of attention to low usage rates, lack of in-depth analysis, and problems such as repeated purchases of instruments and equipment and inaccurate purchase quantities.

 

In the laboratory, RFID tags have many advantages, including the ability to simultaneously track samples from afar without the need for blind searching. This technology is achieved by using passive RFID electronic tags, which emit radio signals in response to RFID readers and writers, who then process relevant information for all samples. Therefore, these RFID electronic tags can easily save time and improve accuracy, especially for large quantities of samples, especially when they cannot be moved, eliminating unnecessary work and maintaining the integrity of asset equipment.
