Problems solved by technology
Therefore, strengthening school attendance requires not only the strict implementation of the management system, but also the cooperation of technical means. The existing technology uses RFID card swiping attendance, but swiping card attendance due to its short recognition distance and short reading time, it is easy to cause omissions. Swiping a card, or bypassing a card machine, etc., in this case, how to use RFID technology attendance more effectively is very necessary

Embodiment Construction
[0046] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0047] figure 1 It is a flowchart of a school attendance method provided by the first embodiment of the present invention, such as figure 1As shown, the method includes the attendance device 1 worn by the students and the service center 2 installed in the school. The method can communicate with the service center 2 of the school through the attendance device 1 worn by the students in real time to perform attendance.
[0048] Specifically, the method includes the following steps:
[0049] S1. Set the RFID identification information in the attendance device 1, and send the RFID identification information to the service center 2 according to the preset frequency; since there may be multiple RFID identification information...

The invention discloses an attendance checking method and system for a school. The system comprises attendance checking devices worn by students and a service center in the school. The method comprises the following steps: S1. setting RFID (radio frequency identification) information in the attendance checking devices and sending the RFID information to the service center at preset frequency; S2. receiving the RFID information in the service center, setting a first time, and if the RFID information is received within the first time, returning an acknowledgment message to the attendance checking device; and S3. setting a second time in each attendance checking device, and after receiving the acknowledgment message, sending the RFID information to the service center at the preset frequency after the second time. The attendance checking method and system have the beneficial effects of being capable of checking the attendance of the students in the school and acquiring the location of the students outside the school.
Description
technical field [0001] The present invention relates to the technical field of RFID, and more specifically, relates to a method and system for checking attendance in schools. Background technique [0002] Radio Frequency Identification (English: Radio Frequency IDentification, abbreviation: RFID) is a wireless communication technology that can identify specific targets through radio signals and read and write related data without establishing mechanical or optical contact between the identification system and specific targets. Radio information transmits data from a tag attached to an item through an electromagnetic field tuned to a radio frequency to automatically identify and track the item. Some tags can get energy from the electromagnetic field emitted by the identifier during identification, and do not need batteries; there are also tags that have their own power supply and can actively emit radio waves (electromagnetic fields tuned to radio frequencies). Tags contain ...
