The cloud platform 2, also referred to as a cloud computing platform, refers to a service based on hardware resources and software resources, and is capable of providing computing, networking, and storage capabilities. It is understood that a cloud platform is a collection of resources of various types that exist on a cloud data center server cluster. These resource sets include hardware resources including servers, memories, Central Processing Units (CPUs), and the like, and software resources including application software, integrated development environments, and the like.
The home agent 3 is a terminal device held by a parent. Specifically, the terminal device may have a call function and a display function, such as a mobile phone, a smart watch, and the like.
On the basis of fig. 1, fig. 2 is a schematic structural diagram of an electronic student's certificate in the prior art. As shown in fig. 2, the electronic student certificate includes: a housing 21 and a positioning unit 22 disposed inside the housing 21.

Further, the first radio frequency identification unit is used for sending a wake-up signal to the microcontroller under the condition that the first radio frequency identification unit or the second radio frequency identification unit is located in the card reading range of the first trigger or the second trigger, and the microcontroller wakes up the second communication unit according to the wake-up signal under the condition that the microcontroller receives the wake-up signal sent by the first radio frequency identification unit, so that the second communication unit sends the identification of the electronic student identity card and the identification of the first trigger or the second trigger to the cloud platform.
The positioning unit 43 includes a GPS positioning subunit 431, a beidou positioning subunit 432, a WIFI positioning subunit 433, and a base station positioning subunit 434; each of the GPS positioning subunit 431, the beidou positioning subunit 432, the WIFI positioning subunit 433 and the base station positioning subunit 434 is connected to the first communication unit.

The card reading range of the first trigger 321 and the second trigger 322 is 2-4 m. In order to avoid the first flip-flop 321 and the second flip-flop 322 from interfering with each other, the distance between the first flip-flop 321 and the second flip-flop 322 may be set to be greater than 4 m.
In addition, the number of the first triggers 321 and the second triggers 322 is not limited, and the number of the first triggers 321 is determined by the length of the card reading range of the first triggers 321 which can cover the whole school gate. Likewise, the number of the second triggers 322 is based on the length of the card reading range of the second triggers 322 that can cover the entire school gate.
Optionally, the operating frequency of the first rfid unit is 125KHZ, and both the first trigger and the second trigger emit 125KHZ rf signals.
Optionally, the operating frequency of the second communication unit is 2.4GHZ, and the operating frequencies of the first reader and the second reader are both 2.4 GHZ.

Optionally, the identifier of the electronic student card may be a card number of the electronic student card, the identifier of the first trigger may be a card number of the first trigger, and the identifier of the second trigger may be a card number of the second trigger.
The working principle of the electronic student identity card will be described in detail below, and for the convenience of the reader, the first trigger 321 is disposed inside the school near the school gate, and the second trigger 322 is disposed outside the school near the school gate.
Wherein, GPS location subunit 431, big dipper location subunit 432, WIFI location subunit 433 and base station location subunit 434 are in operating condition always to GPS location subunit 431, big dipper location subunit 432, WIFI location subunit 433 and base station location subunit 434 gather the student location respectively and in real time, and send to cloud platform 35 through first communication unit 44.
In this embodiment, the first trigger 321 and the second trigger 322 continuously emit radio frequency signals outwards, and the first rfid unit 421 in the electronic student identity card is always in a working state, and the second communication unit is in a dormant state.
In some scenarios, when the student wears the electronic student certificate to enter the campus, the student will first pass through the first trigger 321, and then when the electronic student certificate is located within the card reading range of the first trigger 321, the first rfid unit 421 sends a wake-up signal to the microcontroller 422. The microcontroller 422 wakes up the second communication unit according to the wake-up signal when receiving the wake-up signal sent by the first rfid unit. Meanwhile, the first trigger 321 stores its own identification, for example, an Identity Document (ID), in the electronic student card. Then, the second communication unit obtains the identifier of the electronic student identity card, the ID of the first trigger 321 and the current time, and sends the electronic student identity card, the ID of the first trigger 321 and the current time to the cloud platform 35 through the first reader 331 and the communication gateway 34 which are arranged outside the doorway of the school in sequence.
Subsequently, the student passes through the second trigger 322, and when the electronic student certificate is located in the card reading range of the second trigger 322, the second trigger 322 stores the Identity Document (ID) of the student in the electronic student certificate. Then, the second communication unit obtains the identifier of the electronic student identity card, the ID of the second trigger 322 and the current time, and sends the electronic student identity card, the ID of the second trigger 322 and the current time to the cloud platform 35 through the second reader 332 and the communication gateway 34 which are arranged on the outer side of the school doorway in sequence.
The cloud platform 35 receives the data, and since the identifier of the first trigger is received first, it can be determined that the student enters the campus.
Further, the cloud platform 35 may also send information that the student has arrived to the parent. Or the home keeper end can log in the cloud platform to check the arrival condition of the student.
Therefore, the problem that the positioning unit drifts too much (100 + 1000m) and the positioning position does not accord with the actual position, so that the positioning error exists in the position of the student judged according to the positioning data of the positioning unit, for example, the positioning result shows that the student is outside the campus and the actual student is in the campus, and the school arrival management and the use experience of the parent end are influenced can be solved.
In other scenarios, when the student wears the electronic student certificate to leave the campus, the student will first pass through the second trigger 322, and when the electronic student certificate is located in the card reading range of the second trigger 322, the first rfid unit 421 sends a wake-up signal to the microcontroller 422. The microcontroller 422 wakes up the second communication unit according to the wake-up signal when receiving the wake-up signal sent by the first rfid unit. Meanwhile, the second trigger 322 stores its own identification, for example, an identification number (ID), in the electronic student card. Then, the second communication unit obtains the identifier of the electronic student identity card, the ID of the second trigger 322 and the current time, and sends the electronic student identity card, the ID of the second trigger 322 and the current time to the cloud platform 35 through the second reader 332 and the communication gateway 34 which are arranged on the outer side of the school doorway in sequence.
Next, the student passes through the first trigger 321, and when the electronic student certificate is located in the card reading range of the first trigger 321, the first trigger 321 stores the Identity Document (ID) of the student in the electronic student certificate. Then, the second communication unit obtains the identifier of the electronic student identity card, the ID of the first trigger 321 and the current time, and sends the electronic student identity card, the ID of the first trigger 321 and the current time to the cloud platform 35 through the first reader 331 and the communication gateway 34 which are arranged outside the doorway of the school in sequence.
The cloud platform 35 receives the data, and can determine that the student is away from the campus since the identification of the second trigger is received first.
Further, the cloud platform 35 may also send information to the parent that the student has left the school. Or the home keeper can log in the cloud platform to check the positions of the students.
Therefore, the problem that the positioning unit drifts too much (100 + 1000m) and the positioning position does not accord with the actual position, so that the positioning error exists in the position of the student judged according to the positioning data of the positioning unit, for example, the positioning result shows that the student is in the campus and the actual student is out of the campus, and the management of the school to the student and the use experience of the parent end are influenced can be solved.
In this embodiment, in order to save power, the second communication unit is in a sleep state, and when the student is sensed to enter the campus or go out of the campus, the second communication unit is activated to operate.
It should be understood that the communication gateway arrangement of fig. 3 is exemplary and not limiting. In actual use, those skilled in the art can set the location of the communication gateway according to actual requirements. The position of the reader is not required to be arranged in a guard room, and the reader can be used for reading the card of the electronic student card.
