Mobile internet near-field identification system

Abstract

The invention discloses a mobile internet near-field identification system, and relates to the technical field of identification devices. The identification system comprises a sound near-field identification device, a smart phone and a server, wherein the sound near-field identification device is used for receiving a signal sent by the smart phone or the server and sending a sound wave signal according to the received signal, the sound near-field identification device is connected with the phone in a wired or wireless mode, and the phone exchanges data with the server via a wireless network. The identification system is high in timeliness, good in confidentiality, easy to use and good in client experience.

Description

technical field [0001] The present invention relates to the technical field of identification devices, in particular to a mobile Internet near-field identification system. Background technique [0002] At present, almost all positioning, patrolling, time attendance, access control and other systems on the market use non-contact radio frequency near-field identification technology, that is, RFID (Radio Frequency Identification) technology. This technology uses the principle of electromagnetic field wireless communication, and generally has a card reader (such as the patrol stick of the patrol system) and a locator (such as the ID button and ID card of the patrol system). The card reader and the locator pass short-range radio frequency radio communication to transmit parameters such as the unique number information of the locator to complete identification, location identification, attendance and task authentication identification, etc. This type of positioning and identifica...

Problems solved by technology

[0009] (1) If the system adopts WIFI or bluetooth technology, the mobile APP still needs to carry out the matching process of several operation steps, which is cumbersome

[0010] (2) When WIFI and Bluetooth are within a short distance, such as within 10 meters, the technical implementation methods for distinguishing two or more docking devices (locators or receivers) are relatively complicated, and the user experience is extremely poor

[0011] (3) If the NFC method is adopted, it is mandatory that all matching mobile phones have NFC functions, and its versatility is very poor, and a large number of low-end mobile phones are not equipped with it.

In the teaching building with extremely high classroom density, this work is extremely cumbersome. If you are not careful, you will be connected to the RF receiver in the next classroom, and the consequences will directly lead to teaching accidents.

Therefore, the multimedia classroom central control system using WIFI or Bluetooth technology to control audio-visual equipment has not been popularized, and it is very difficult to promote
