The course of work of short message sending system of the embodiment of the present invention is as follows:

1. electronic identity card for students was to send broadcast message (work attendance broadcast) cycle with 1 second, broadcast message uses 2.48GHz frequencies Rate;10 byte, content include Packet type, ID number and reserved field to the data of work attendance broadcast altogether.

2.RF base stations receive broadcast message, and by after the ID number collection of electronic identity card for students, are transferred to system server.

3. note data is wrapped check-in system server by parents of student by wechat client, note data bag includes short Believe the account of content and student in system.Student's account and electronic identity card for students ID number are corresponded to and carried out by system server software Replace.

4. system server software searches the RF base stations for reporting specified student's identity card ID recently, note data bag is issued to this RF base stations.

5. in the case of reporting this short message paid-in in no RF base stations, if new RF base stations have reported specified Raw card id information, note data bag is issued to new RF base stations by system server, until there is RF base stations to report this short message The information received.

6. electronic identity card for students with the time interval of 30 seconds, sends the wireless data of short message enquiry.Short message enquiry without line number According to identical with work attendance broadcast data form, length is also 10 bytes, and content includes Packet type, ID number, short message sequence number and request bag Sequence number.Short message sequence number is the condition code of short message, and request bag sequence number is next bag sequence number that electronic identity card for students inquires about a short message. In first bag inquiry data, short message sequence number and request bag sequence number all fill out 0.After sending inquiry signal, into time window is received, connect Time receiving long 1ms.

After 7.RF base stations receive the wireless data of short message enquiry, given back in the reception time window of electronic identity card for students It is multiple;If the short message of the electronic identity card for students, just short message content is replied, otherwise replys empty bag.Short message content data packet length 32 bytes, including Packet type, base station IDs, student's identity card ID, short message sequence number, bag sequence number and short message content.

8. the longer packet of short message content, RF base stations issuing to electronic identity card for students is completed by repeatedly interaction;

The request bag sequence number that 9.RF base stations are reported by electronic identity card for students judges whether short message content is transmitted.Transfer Cheng Hou, RF base station send the confirmation data that this short message has been sent completely, system server software knot to system server software Beam issues process, and notifies wechat client short message successfully to issue.

10. receiving the electronic identity card for students of short message by showing that icon prompts student to have short message arrival, student is adjusted by button Access is taken, in liquid crystal display screen display short message content.

Using the short message sending system of the present embodiment, short message can be issued to specified by parent or school by internet Electronic identity card for students on.Parent can be sent short message content, by under short message by modes such as computer, cell phone application or wechats Hair system is transferred to electronic identity card for students.School can issue the content such as specific short message and broadcast notice.

The effect of above example of the present invention is:

The function that electronic identity card for students receives short message is realized, available for interactions such as parent's message, campus broadcasting notices;

On the hardware foundation of existing classroom interaction answering card, the function of receiving short message is realized, electronic identity card for students increases in itself The cost added is considerably less (only storage or word-base chip);

RF base stations are disposed in use range, receive the work attendance broadcast of electronic identity card for students, the road issued in this, as short message By foundation;Moreover it is possible to the work attendance broadcast data according to suffered by RF base stations, realizes student's zone location.

Using being calculated exemplified by 2.4GHz frequencies, energy consumption of the electronic identity card for students for short message, only to carry out within tens seconds Data interaction, the time of a data interaction, electric current was less than 15mA within 2ms.Average 1 year power consumption deficiency 50mAH, meet the requirement of button cell power supply.
