Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 shows the module of the embodiment of dual mode communication data retransmission cell arrangement of the present utility model.See also Fig. 1, the dual mode communication data retransmission cell arrangement of the present embodiment comprises: communication module 1, Big Dipper protocol conversion mainboard 2, Big Dipper communication module 3, GPRS communication module 6, power module 4.Better can also comprise USB expansion module 5.
Communication module 1 is connected with the front end on-Line Monitor Device.Communication module 1 comprises serial data interface 10 and network interface 11.Network interface 11 for example is the RJ-45 network interface.
Big Dipper protocol conversion mainboard 2 connects communication module 1, the message that meets state's net or southern net transmission protocol that the front end on-Line Monitor Device is uploaded by TCP/IP or udp protocol converts Big Dipper protocol massages to, and the response message that the big-dipper satellite passage is returned converts the message that meets state's net or southern net transmission protocol to.Big Dipper protocol conversion mainboard 2 adopts the master control borad of ARM9 chip.
Big Dipper communication module 3 connects Big Dipper protocol conversion mainboard 2, carries out data retransmission by the big-dipper satellite passage.
GPRS communication module 6 connects communication module 1, carries out data retransmission.
Power module 4 connects Big Dipper protocol conversion mainboard 2, is responsible for powering to device.
USB expansion module 5 connects Big Dipper protocol conversion mainboard 2, carries out the embedded program upgrading of device by USB interface.
Device is connected with the front end on-Line Monitor Device by communication module 1, communication mode is TCP/IP or UDP mode, when being weaker than preset value, the GPRS signal switches to Big Dipper communication mode, in Big Dipper protocol conversion mainboard 2, realize the conversion that TCP/IP or UDP communication protocol arrive Big Dipper communication protocol, carry out data retransmission by Big Dipper communication mode; When being better than preset value, the GPRS signal directly carries out data retransmission by the GPRS mode.
Fig. 2 shows the principle of the dual mode communication data retransmission unit based on GPRS Big Dipper short message service of the present utility model.Dual mode communication data retransmission unit (DTU) device based on the service of GPRS Big Dipper short message is divided into based on dual mode communication data retransmission unit (DTU) the on-line equipment end of GPRS Big Dipper short message service and dual mode communication data retransmission unit (DTU) the main website forwarding end of serving based on GPRS Big Dipper short message.
See also Fig. 3 and Fig. 5, dual mode communication data retransmission unit (DTU) the on-line equipment end of serving based on GPRS Big Dipper short message mainly is comprised of ethernet side module, GPRS serial ports end, Big Dipper serial ports end, main control module, power module and USB expansion module.
The ethernet side module is received in the message that line apparatus sends in real time in the UDP mode, and when communicating by letter in the GPRS mode, main control module will not done any processing to message, directly send to the GPRS base station.A little less than the GPRS signal, be not enough to guarantee that data normal transmission timer automatically switches to Big Dipper communication mode.When to the north of square sheet of paper used for painting or calligraphy formula when communication, main control module is resolved the maximum whether length surpass Big Dipper card and is sent text length.If it is unpack, then be packaged into Big Dipper message, send to big-dipper satellite by Big Dipper serial ports end.If otherwise directly were packaged into Big Dipper message, would send to big-dipper satellite.
Big-dipper satellite receives the communication information that big-dipper satellite issues simultaneously in real time except sending main control module the packed Big Dipper message.Then by Ethernet, be handed down to the on-line monitoring client terminal device in the mode of TCP/IP or UDP.
See also Fig. 4 and Fig. 6, when communicating by letter in the GPRS mode, dual mode communication data retransmission unit (DTU) the main website forwarding end of serving based on GPRS Big Dipper short message directly sends to message on the IP and port of main website with TCP/IP or UDP mode by Ethernet.When to the north of square sheet of paper used for painting or calligraphy formula when communication, transmit end based on dual mode communication data retransmission unit (DTU) main website of GPRS Big Dipper short message service and formed by PC and Beidou antenna, it is actual to be the retransmission process that moves at PC.Beidou antenna links to each other with the serial ports of PC by 232 serial ports, receives the data that big-dipper satellite sends by the PC serial ports, then sends on the IP and port of main website by the mode of Ethernet with TCP/IP or UDP.Transmit end based on dual mode communication data retransmission unit (DTU) main website of GPRS Big Dipper short message service and will receive the satellite data message of the coming group bag of unpacking, last mode with TCP/IP or UDP sends to the main website end.Receive in real time simultaneously the order that main website issues, send to big-dipper satellite under the prerequisite that allows to send at Big Dipper card.If Big Dipper card does not allow, then preserve first until obtain the authority that Big Dipper card sends.
To sum up, device of the present utility model is applicable to all on-Line Monitor Device, device based on the dual mode communication data retransmission unit (DTU) of GPRS Big Dipper short message service can receive any message of communicating by letter with TCP/IP or UDP mode in real time by Ethernet, does not exist because installing difference to produce inapplicable situation.In addition, this device can be supported online upgrading, in the situation that do not cut off the power supply, can realize the program upgrade of all DTU equipment with a USB flash disk.Device is supported in line states, insert USB flash disk at the USB interface end, dual mode communication data retransmission unit (DTU) device based on the service of GPRS Big Dipper short message can be identified the executable file that has incomparable current executable file to upgrade in the USB flash disk automatically, executable file in the USB flash disk can be copied in the equipment if having, copy finishes afterwards this equipment of autoboot, finishes the online upgrading of program.If there is not executable file, perhaps this document does not upgrade than the executable file that is now moving, and is not left intact, and can in the situation that do not cut off the power supply, just can finish program upgrade by a USB flash disk like this.This device can also the Configuration Online important parameter, for different DTU devices, because contained Big Dipper card number is different, so need to carry out to different DTU equipment the setting of relevant parameter.Here be by the setting of USB flash disk realize target Big Dipper card, local Big Dipper card, communication frequency, retransmission mechanism, make this equipment have more flexibility and adaptability.This device stability is good, and suitable application area is wide especially, and the master control borad that adopts is ARM9, and has embedded linux operating system, and institute is so that processing speed is faster, and stability is better.Automatically switch to Big Dipper communication mode when having solved a little less than the GPRS signal, when the GPRS signal is strong, automatically switch, guaranteed that like this transfer of data can not interrupt because of signal problem, make its suitable application area more extensive.
Above-described embodiment provides to those of ordinary skills and realizes and use of the present utility model; those of ordinary skills can be in the situation that do not break away from invention thought of the present utility model; above-described embodiment is made various modifications or variation; thereby protection range of the present utility model do not limit by above-described embodiment, and should be the maximum magnitude that meets the inventive features that claims mention.
