Description
Technical field
The present invention relates to engineering machinery remote monitor supervision area, particularly relate to a kind of data transmission method and system that is applied to engineering machinery remote monitor supervision area.
Background technology
The long distance control system of engineering machinery field comprises three parts: long-distance monitorng device, information transfer server and Surveillance center, wherein, long-distance monitorng device and Surveillance center form two data terminals of engineering machinery remote monitering system.
Long-distance monitorng device is installed on the engineering machinery, collect the running state information of engineering machinery, and the running state information of collecting is transferred to Surveillance center by data transmission channel, simultaneously, long-distance monitorng device obtains the control information that Surveillance center sends, this control information is sent to the control unit of engineering machinery, and control unit Control Engineering machinery is finished relevant action.
Surveillance center is responsible for receiving the health information that is sent by long-distance monitorng device, this health information is discerned, is shown and preserves, and generate control information according to this health information, again this control information is sent to long-distance monitorng device.
The information transfer server provides intermediary service for the transfer of data between Surveillance center and long-distance monitorng device.
At present, long-distance monitorng device and Surveillance center adopt GPRS transmission mode or SMS (short message) transmission mode more.Consult Fig. 1, be the signaling diagram of existing long-distance monitorng device and the employing GPRS of Surveillance center transmission mode.
Step S101, long-distance monitorng device send the GPRS connectivity request message to Surveillance center.
Step S102, Surveillance center receive this connectivity request message, reply GPRS to long-distance monitorng device and connect confirmation.
Step S103, long-distance monitorng device receive this GPRS and connect confirmation.Long-distance monitorng device and Surveillance center adopt the GPRS transmission mode to carry out transfer of data.
The GPRS transmission mode can realize the continuous transmission of bulk information, and data transmission efficiency is higher, and the GPRS transmission mode charges according to data transfer throughput, and cost is lower.But, the GPRS transmission mode is had relatively high expectations to outside signal strength signal intensity and whole long distance control system, before message transmission, must exist stable GPRS to be connected between long-distance monitorng device and Surveillance center two data terminals, the disconnection that this GPRS connects has uncertainty constantly usually, influence the continuity of transfer of data, and the GPRS transmission mode externally lacks the stability and the reliability of transmission under the more weak situation of signal strength signal intensity.
Consult Fig. 2, be the signaling diagram of existing long-distance monitorng device and the employing SMS (short message) of Surveillance center transmission mode.
Step S201, long-distance monitorng device send the connectivity request message that comprises self identification information in the mode of short message to Surveillance center.
Step S202, Surveillance center receive this connectivity request message, reply the GPRS that comprises self identification information to long-distance monitorng device and connect confirmation.
Step S203, long-distance monitorng device receive this GPRS and connect confirmation.Long-distance monitorng device and Surveillance center adopt SMS (short message) transmission mode to carry out transfer of data.
SMS (short message) transmission mode stability is higher, but the amount of information that transmission wall scroll note is comprised is less, and data transmission efficiency is lower and cost is higher.
By above analysis as can be known, no matter long-distance monitorng device and Surveillance center adopt GPRS transmission mode or SMS (short message) transmission mode, all has certain defective, can not well satisfy between long-distance monitorng device and Surveillance center, carry out reliable and stable, efficiency of transmission is higher, and lower-cost transfer of data.
