Utility model content:
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provides a kind of GPRS DTU data transmission equipment, mainly solve existing GPRS DTU data transmission equipment cost high, easily cause the problem such as Transmission and error of transmission.
The technical solution of the utility model is, a kind of GPRS DTU data transmission equipment, comprise GPRS-DTU main frame, its special character is, GPRS-DTU main frame comprises GPRS-DTU central processing unit, power interface, house dog, FLASH storage, GPRS wireless module, antennal interface, SIM card, serial interface; Described power interface, house dog, FLASH store and are directly connected with GPRS-DTU central processing unit; Described GPRS wireless module, serial interface are connected with GPRS-DTU central processing unit by serial communication circuit; Antennal interface, SIM card are directly connected with GPRS wireless module; GPRS-DTU main frame connects subscriber equipment by serial ports; GPRS network base station connects GPRS-DTU main frame and server respectively by GPRS network; Described server is connected with remote monitoring center by Internet network.
Compared with the prior art a kind of GPRS DTU data transmission equipment described in the utility model has following good effect: (1) software and hardware house dog is designed, and ensures system stability; (2) GPRS-DTU central processing unit is 32 high speed arm processors, can process the conversion of various protocol data more at high speed, solves in the industry the knotty problem such as " false online ", " false crash ", " working as machine "; (3) the built-in reverse-phase protection of power interface and overvoltage protection, the built-in 15KV esd protection of SIM card interface, antennal interface lightning protection, the built-in 15KV esd protection of serial interface: RS232/ 485/422, can ensure that system stability is reliable; (4) support that the wake-up modes such as note, voice, data and time-out disconnect network and connect, support short message backup and alarm; (5) serial ports software upgrading and remote maintenance is supported; (6) intelligence is anti-goes offline, and supports on-line checkingi, maintains online, go offline and automatically redial, guarantee that equipment is always online; (7) equipment cost is low, the transmission demand of large-data operation can be realized, with subscriber equipment plug and play, installing and simple, easy to usely take into account again the stability of technical grade DTU product and the GPRS DTU data transmission equipment of reliability simultaneously, is aly user can be allowed to realize easy-to-use GPRS DTU product handy again.
Accompanying drawing illustrates:
Fig. 1 is general frame schematic diagram of the present utility model.
Embodiment:
Further illustrate the utility model below in conjunction with accompanying drawing and concrete enforcement, illustrated embodiment, only for explaining the utility model, is not for limiting scope of the present utility model.
Embodiment 1, see Fig. 1, suitable GPRS-DTU main frame 1, GPRS-DTU main frame 1 is selected to comprise GPRS-DTU central processing unit 6, power interface 7, house dog 8, FLASH storage 9, GPRS wireless module 10, antennal interface 11, SIM card 12, serial interface RS232/485/422 13 according to design requirement; Power interface 7, house dog 8, FLASH are stored 9 and be directly connected with GPRS-DTU central processing unit 6, be connected with GPRS-DTU central processing unit 6 by serial communication circuit by GPRS wireless module 10, serial interface: RS232/485/422 13, antennal interface 11, SIM card 12 are directly connected with GPRS wireless module 10; GPRS-DTU main frame 1 is connected subscriber equipment 2 by serial ports, is responsible for sample user information, GPRS network base station 3 connects GPRS-DTU main frame 1 and server 4 respectively by GPRS network, is responsible for the two-way communication between GPRS DTU data transmission equipment and server; Again by server 4 by Internet network and remote monitoring center: mobile phone/PC 5 is connected, and is responsible for carrying out to user profile analysiss and shows, records early warning etc.
A kind of GPRS DTU data transmission equipment described in the utility model, during work, first insert one open logical GPRS function and directly access the SIM card of the Internet by NET, antenna is loaded onto to equipment, equipment is passed through serial interface: RS232/485/422 is with the hydrology, electric power, meteorological, the subscriber equipment serial ports such as environmental protection link up the scene of being placed on, by power interface power supply to the device, first read the running parameter preserved in inner FLASH after GPRS DTU powers on and (comprise GPRS dialing parameters, serial port baud rate, data center IP address etc., configure in advance), the internal memory that this FLASH has a super large carrys out buffer memory client and sends data, receive super large packet simultaneously, guarantee that data are not lost, then be registered to GPRS network, carry out GPRS PPP dialing, after dial-up success, the implicit IP address (being generally 10.X.X.X) that acquisition one is distributed by movable random by GPRS DTU, GPRS DTU, by parameters such as the IP address of data center and port numbers, initiates TCP or UDP communication request to teledata monitoring center, after the response obtaining teledata monitoring center, namely GPRS DTU thinks and shakes hands successfully with teledata monitoring center, and then just keep this communication connection to exist, if broken communication connection, GPRS DTU will shake hands with center immediately again always.Because TCP/UDP communication connection is set up, just can carry out data double-way and communicate.The analysis can being carried out data by teledata monitoring center is shown, is recorded early warning etc.This equipment installs stability and the reliability simultaneously taking into account again technical grade DTU product simple, easy to use, can realize the transmission demand of large-data operation, is aly user can be allowed to realize easy-to-use GPRS DTU product handy again.
