Wherein: 1-GPRS data transmission device, 2-GSM communicator, 3-data monitoring device, 4-controller, 5-synchronous DRAM, 6-Flash storer, 7-jtag test device, 8-power supply, 9-RS232 serial ports, 10-GPRS communicator, 11-data storage server, 12-data-carrier store, 13-Internet access device, 14-GPRS network, 15-Internet grid line.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As shown in Figure 1, the present embodiment provides a kind of GPRS wireless system for transmitting data based on dynamic IP addressing being comprised of GPRS data transmission device 1, GSM communicator 2 and data monitoring device 3, GPRS data transmission device 1 is taken on the effect of data transmission network articulation point in whole system, and each node data information simple process converging is sent to data monitoring device 3; GPRS data transmission device 1 will be stored in Flash storer 6 after each node data information processing of converging, controller 4 is controlled GPRS communicator 10 access of radio network by sending instruction, according to the IP of data center address and the port numbers of storage in GPRS communicator 10, find online data monitoring device 3, by GPRS, be connected with Internet network, communication link can send data to data monitoring device 3 after being communicated with.After GPRS communicator 10 access network successes simultaneously, obtain unique dynamic IP addressing, GPRS communicator 10 sends and is stored in data monitoring device 3 by this IP address with SMS short message way, data monitoring device 3 is found this IP address and is connected, can be to the request that sends access GPRS data transmission device 1.After 10 suspensions of GPRS communicator, access of radio network obtains IP address and changes again, therefore when GPRS communicator 10 each access network, all can again the dynamic IP addressing of obtaining be sent to data monitoring device 3, the connection of assurance data transmission channel.Data monitoring device 3 comprises data-carrier store 12, data storage server 11, Internet access device 13 etc., is connecting GSM communicator 2 on data storage server 11.GPRS data transmission device 1 transfers data to data monitoring device 3 and is stored in data-carrier store 12, when need to checking data message, sends by the PC of access Internet network the request of checking, this request is sent to data storage server 11 by these requests of data-carrier store 12 response, in data-carrier store 12, recall the data message meeting the demands be sent to access Internet network PC confession its check.The PC of access Internet network also can send the request of access GPRS data transmission device 1, after PC access Internet, obtain IP address and open PORT COM, the IP address information that exists the GPRS data transmission device 1 of data monitoring device 3 to send over by Internet and GPRS network searching is connected with it, after network-in-dialing, request of access is sent to GPRS data transmission device 1, respond this request data are recalled and feed back to Surveillance center.When data monitoring device 3 access networks obtain IP address, GSM communicator 2 sends and is kept at GPRS data transmission device 1 in the mode of SMS short message by IP address and PORT COM, for GPRS data transmission device 1 is found, connection data supervising device 3 provides destination address.The IP address of same data monitoring device 3 is also changeable, therefore at data monitoring device 3 access Internet, obtains GSM communicator 2 behind IP address and will automatically send the old address that preserve in replacing GPRS data transmission device 1 new IP address.
