Order；It is then to complete COS and download, storage COS downloads Success Flag, waits host query；
(8) host query respectively writes the COS download success/failure flags of card unit, makees throwing card to the IC-card of failure flags or mends card
Processing.
7. method according to claim 5, it is characterised in that for the individuation data APDU orders of fabrication, main frame from
Database obtain individuation data bag, and be encrypted rear unicast be sent to correspondence write card unit；Card unit is write to receive after data
Decoded, card is then write again；Transmit comprising the following steps that for individuation data APDU orders：
(1) main frame reads individuation data bag from database server；
(2) main frame carries out CRC check to the individuation data bag that reads, successful then perform next step, otherwise re-reads individual
Property packet；
(3) main frame is sent to from the one APDU order of taking-up of individuation data bag and writes card unit；
(4) write card unit the APDU orders received are decrypted and CRC check operation, it is successful then progress APDU orders write card
Operation, otherwise this of request repeat APDU orders；
(5) the last item APDU orders of individuation data bag are judged whether to, it is no, turn to step (3) and read next
APDU orders；It is then to complete individuation data bag and download.
(6) judge whether the download of COS packets completes；It is that then current IC-card fabrication terminates, no, continues waiting for until COS numbers
Terminate according to the download of bag.
8. method according to claim 7, it is characterised in that system obtains data and in main frame by adding from database
Unicast is carried out after close algorithm in LAN, is just decrypted and writes on card after card unit receives the data of encryption when writing；
In system power failure, the data auto-destruct.
9. method according to claim 5, it is characterised in that the operating procedure for writing card unit is specific as follows：
(1) system electrification；
(2) complete after system configuration, start card producing system, card producing system includes 4 threads；Thread 1 be heartbeat thread, regularly to
Main frame sends heartbeat message, tells main frame currently to write card unit fault-free；Thread 2 is network interface watcher thread, and wait connects from network interface
Receive data or order；Thread 3 is command process thread, for handling the information that main frame is sended over；Thread 4 is to write card line
Journey, for realizing the read-write operation with card；
(3) order to be received such as；
(4) COS data APDU orders are write when receiving, then starts and write COS data threads；The thread waits COS data APDU first
Order is transferred to after internal memory by above-mentioned mechanism, then CRC check is carried out to COS data APDU orders, only when data are correct
Just it is inserted into after errorless and writes card queue, writing operation is carried out by writing card line journey；Mistake then return to step (3).
(5) receive when writing individuation data APDU orders, individuation data thread is write in startup；The thread number to be personalized such as first
Individuation data APDU orders are received from network interface according to order, then individuation data APDU orders are decrypted and CRC schools
Operation is tested, is just inserted data into after individuation data APDU order successful decryptions and writes card queue, row write card behaviour is sticked into by writing
Make；Decryption failure return to step (3)；
(6) after receiving reading and writing card location mode order, start transmission and write card location mode thread；Write card location mode thread
Including writing whether card unit is working, whether working condition is correct, CPU running statuses and internal storage state；Data are prepared
Afterwards, the thread will write card location mode group bag and be sent to main frame；
(7) step (3) is continued executing with.
