If be in the wireless data transmission state then revise status word, battery has fired is revised status word once more;
If be in the wireless data accepting state, then whether judgment data is the data of this subnet, is just to receive data and revise status word, is not then to abandon data and revise status word;
If be in the serial data accepting state, then revise status word, receive and revise status word once more;
If be in the serial data transmit status, then revise status word, sending finishes revises status word once more.
9. according to the intelligent wireless medical monitoring method of claim 5, the job step of wherein said monitoring center background information management system comprises:
(1) user's login process:
1) read configuration file, acquiescence shows the user name of last login in user name.
When 2) verifying, the data of this user name in the Query Database if there is no, ejects error box; If exist, the input password is encrypted the back carry out verification, if mistake ejects error box with the field among the data base; If correct, the then parameter of reading system from configuration file, and definite this user's operating right;
(2) serial communication flow process:
When packet is received in the base station, just begin to send to PC by serial ports.PC will become unsigned int mComm from the byte conversion that serial ports receives, then mComm resolved,
If m_bstart=true, then explanation begins to receive from packet header at this moment, resolves the command word among the Str
If √ m is bAck=true, then this is the affirmation bag of packet, the complete reception of packet PC before the representative;
If be data among the √ Str, judge then whether this packet is redundant, if then composing Str, redundant data is NUL, receive and finish; If not redundancy, then data are deposited among the data base;
Show if desired, judge then whether body temperature is normal, if normal, demonstration information in normal frame then; If unusual, demonstration information in unusual frame then;
(3) patient's data management flow process:
Newly-increased/" preservations " revised: judge whether necessary information all fills in earlier during beginning, if do not fill in then jump out the correct fill message of prompting frame prompting user automatically; Finish if all correctly fill in as requested, then the base station sends binding information to serial ports according to institute's fill message, if it is true to reply bag m_bAkc=, then binding successfully also, the preservation data arrives the data base; If reply bag m_bAkc=vacation, then eject the dialog box of Bind Failed;
Deletion: the binding relationship that refers to delete patient and monitoring terminal.Concrete operations are: behind the selected object that needs to delete, and the record of this monitoring terminal of deletion in database table Tag_Info;
Inquiry: the essential information that obtains this patient according to querying condition (name, monitoring terminal ID);
(4) the real-time flow for displaying of patient temperature information;
(5) the inquiry of historical data and analysis process; And
(6) system maintenance flow process.
