It is connected；PC machine is connected with projecting apparatus, and is connected with cloud platform by Internet.
This system completes indoor accurate position using the base stations iBeacon for being equipped with CC2541 chips.IBeacon Bluetooth base. stations
Signal is transmitted by the broadcasting channel of bluetooth, i.e., to the data such as continuous broadcast self ID around.The data of iBeacon broadcast can be with
Resolve to 4 parts:Proximity UUID, Major, Minor and Measured Power.Proximity UUID are standards
32 bit identifiers, the utility model are defined as item types (i.e. attendance scene) and using unit (schools)；Major and Minor
All be 16 can sets itself identifier, the utility model is used for Major to identify specific Teaching-building in the school, Minor
(wherein having contained specific floor information) is numbered for identifying classroom；Measured Power correspond to the Tx in broadcast
The value of Power indicates the signal strength values (Received measured at 1 meter of distance iBeacon equipment (i.e. Bluetooth base. station)
Signal Strength Indication, abbreviation RSSI), with complement code the results show that can complete to be accurate to rice by the value
The range measurement of grade.Floor number, classroom number (i.e. location information) are sent to all mobile terminal (hands by the base stations iBeacon
Machine).
Mobile terminal is by writing App come the bluetooth module in control terminal.The number of iBeacon base station broadcasts is received first
According to then being judged with a distance from the base stations iBeacon (i.e. classroom) according to the RSSI value that mobile terminal receives, by between the two
Distance whether in the threshold value of setting, to judge that student whether in specified classroom, gets diligent information.Finally will
To diligent information, mobile terminal Bluetooth MAC address, receive the base stations iBeacon the information such as data (floor number, classroom number) it is logical
It crosses bluetooth and is sent to control terminal, control terminal judges it is diligent whether student arrives on time in conjunction with local RTC time, automatic to realize
It registers.According to this method before the class, on judge four times within 10 minutes after class and before school end within 10 minutes, to sentence
It is disconnected whether to be late, whether leave early.
Mobile terminal, can also be according to the classroom test question that teacher shows on large screen other than judging attendance information
Mesh (or questionnaire survey), scene responds, and by response message (i.e. answer) together with letters such as the Bluetooth MAC address of mobile terminal
Breath is sent to control terminal by bluetooth.Terminal to diligent information, Bluetooth MAC address, local zone time, receive the base stations iBeacon
Data, response message etc. can synchronize and be saved on local TinyDB databases.Attendance information, the historical record in high in the clouds etc. can lead to
The App softwares of operation on mobile terminals are crossed to inquire at any time.
Control terminal uses the STM32L476RE microcontrollers of STMicw Electronics (ST) company for main control chip, passes through two
Serial ports is connected with microcontroller and low-power consumption bluetooth module USR-BLE100 respectively.Bluetooth module is for receiving mobile terminal transmission
The attendance information, location information and the reply data (topic answer or voting result) that come over, and judge in conjunction with local RTC time
Whether student arrives diligent on time.Control terminal stores these data on local sqlite databases, and turns USB by serial ports simultaneously
Interface is sent to microcontroller.
Micro controller data processing software is connected by USB (virtual serial port) with control terminal.Be mainly used at random call the roll with
The statistical analysis of reply data, and result is illustrated in by projecting apparatus on large screen, while being uploaded to by Internet
Cloud platform.Micro controller data processing software is write using VC++.By generate random function and be mapped on student number realize with
Machine is called the roll, is putd question to, and by the way that the sound card of text-to-speech PC machine to be played to the name of student, the image of student is simultaneously displayed on greatly
On screen；Student is shown in the topic on large screen to teacher and is answered a question with mobile terminal (mobile phone), answer and learner answering questions
The statistical result real-time display of situation is on large screen.
Cloud platform uses new billow cloud.The SAE of new billow cloud provides many services such as database, counter, identifying code, reliability
Height, using with how many pairs of how many Flexible toll policy modes, exploitation is low with use cost, and developer does not need purchase of equipment, also without
It needs oneself to develop again.This system server-side code is deployed in the SAE platforms of Sina.Mainly the MySQL of SAE is used to take
Business, KVDB services.Wherein MySQL services the management mainly as main service data.KVDB is serviced in relevant business
The variable of key-value pair is utilized in code.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, without deviating from the technical principle of the utility model, it can also do
